MDEV-23580: WSREP_SST: [ERROR] rsync daemon port has been taken This commit contains a large set of further bug fixes and improvements to SST scripts for Galera, continuing the work that was started in MDEV-24962 to make SST scripts work smoothly in different network configurations (especially using ipv6) and with different environment settings: 1) The ipv6 addresses were incorrectly handled in the SST script for rsync (incorrect address substitution for establishing a connection, incorrect address substitution for bind, and so on); 2) Checking the locality of the ip-address in SST scripts did not support ipv6 addresses (such as "[::1]"), which were falsely identified as non-local ip, which further did not allow running two SSTs on different local addresses on the same machine. On the other hand, this bug masked some other errors (related to handling ipv6 addresses); 3) The code for checking the locality of the ip address was different in the SST scripts for rsync and for mysqldump, with individual flaws. This code is now made common and moved to wsrep_sst_common; 4) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) in the wait_for_listen() and check_pid_and_port() functions did not process ipv6 addresses correctly in all cases (not for all branches); 5) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) in the wait_for_listen() and check_pid_and_port() functions for some code branches could give a false positive result due to the textual match of prefixes in the port number and/or PID of the process; 6) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) was supported through different utilities in SST scripts for mariabackup and for rsync, and with various minor flaws in the code. Now the code is still different in these scripts, but it supports a common set of utilities (lsof, ss, sockstat) and is synchronized across patterns that used to check the output of these utilities; 7) In SST via mariabackup, the signal about readiness to receive data is sometimes sent too early - immediately after listen(), and not after accept() (which are called by socat or netcat utility). 8) Checking availability of the some options of some utilities was done using the grep pattern, which easily gives false positives; 9) Common name (CN) for local addresses, if not explicitly specified, is now always replaced to "localhost" to avoid the need to generate many separate certificates for local addresses of one machine and not to depend on which the local address is currently used in test (ipv4 or ipv6, etc.); 10) In tests galera_sst_mariabackup_encrypt_with_key_server and galera_sst_rsync_encrypt_with_key_server the correct certificate is selected to avoid commonname (CN) mismatch problems; 11) Further refactoring to protect against spaces in file names. 12) Further general refactoring to eliminate bash-specific constructs or to improve code readability; 13) The code for setting options for the nc (netcat) utility was different in different scripts for SST - now it is made identical. 14) Fixed long-time broken encryption via xbcrypt in combination with mariabackup and added support for key-based encryption via openssl utility, which is now enabled by default for encrypt=1 mode (this default mode can be changed using a new configuration file option "encypt-format=openssl|xbcrypt", which can be placed in the [mysqld], [sst] or in the [xtrabackup] section) - this change will allow us to use and to test the encypt=1 encryption without installing non-standard third-party utilities.

MDEV-25818: RSYNC SST failed due to busy port This commit reduces the likelihood of getting a busy port on quick restarts with rsync SST (problem MDEV-25818) and fixes a number of other flaws in SST scripts, adds new functionality, and also synchronizes the xtrabackup-v2 script with the mariabackup script (the latter applies only to the 10.2 branch): 1) SST via rsync: rsync and stunnel does not always get the right time to complete by correctly handling SIGTERM. These utilities are now given more time to complete normally (via normal SIGTERM processing) before we move on to using "kill -9"; 2) SST via rsync: attempts to terminate an rsync or stunnel process (via "kill" utility) are only made if it did not terminated on its own; 3) SST via rsync: if a combination of stunnel and rsync is used, then we need to wait for both utilities to finish or stop, not just one of them; 4) The config file and pid file for stunnel are now deleted after successful completion of SST on the donor node; 5) The configs and pid files from rsync and stunnel should not be deleted unless these utilities succeed (or are sucessfully terminated) on the joiner node; 6) The configs and pid files now excluded from transfer via rsync; 7) Spaces in paths are now valid for config files as well (when used with SST via rsync or mariabackup / xtrabackup[-v2]); 8) SST via mariabackup: added preliminary verification of keys and certificates that are used when establishing a connection using SSL (to avoid long timeouts and improve diagnostics) - by analogy with how it is done for the xtrabackup-v2 (plus check for CA file), while that check is skipped if the user does not have openssl installed (or does not have diff utility); 9) Added backup-threads=<n> configuration option which adds "--parallel=<n>" for mariabackup / xtrabackup at backup and move-back stages; 10) Added encrypt-threads and encrypt-chunk-size configuration options for xbcrypt management (when xbcrypt is used); 11) Small optimization: checking the socat version and adding a file with parameters for 2048-bit Diffie-Hellman (if necessary) is done only if the user has not specified "dhparam=" in the "sockopt" option value; 12) SST via rsync now supports "backup-threads" configuration option (in server-related sections or in the "[sst]"); 13) Determining the number of available processors is now supported for FreeBSD + mariabackup/xtrabackup: before that we might have problems with "--compact" (rebuild indexes) or qpress on FreeBSD; 14) The check_pid() function should not raise an error state in the rare cases when the pid file was created, but it is empty, or if it is deleted right during the check, or when zero is read from the pid file; 15) Iproved templates that are used to check if a requested socket is "listening" when using the ss utility; 16) Shortened some other templates for socket state utilities; 17) Temporary files created by mariabackup / xtrabackup are moved to a separate subdirectory inside tmpdir (so they don't get mixed with other temporary files, which can make debugging more difficult); 18) 10.2 only: the script for SST via xtrabackup-v2 has been brought in full compliance with all the bugfixes made for mariabackup (as it previously contained many flaws compared to the updated script for mariabackup).

MDEV-27524: Incorrect binlogs after Galera SST using rsync and mariabackup This commit adds correct handling of binlogs for SST using rsync or mariabackup. Before this fix, binlogs were handled incorrectly - - only one (last) binary log file was transferred during SST, which then led to various failures (for example, when trying to list all events from the binary log). These bugs were long masked by flaws in the primitive binlogs handling code in the SST scripts, which causing binary logs files to be erased after transfer or not added to the binlog index on the joiner node. Now the correct transfer of all binary logs (not just the last of the binary log files) has been implemented both for the rsync (at the script level) and for the mariabackup (at the level of the main utility code). This commit also adds a new sst_max_binlogs=<n> parameter, which can be located in the [sst] section or in the [xtrabackup] section (historically, supported for mariabackup only, not for rsync), or in one of the server sections. This parameter specifies the number of binary log files to be sent to the joiner node during SST. This option is added for compatibility with old SST scripting behavior, which can be emulated by setting the sst_max_binlogs=1 (although in general this can cause problems for the reasons described above). In addition, setting the sst_max_binlogs=0 can be used to suppress the transmission of binary logs to the joiner nodes during SST (although sometimes a single file with the current binary log can still be transmitted to the joiner, even with sst_max_binlogs=0, because this sometimes necessary in modes that involve the use of GTIDs with Galera). Also, this commit ensures correct handling of paths to various innodb files and directories in the SST scripts, and fixes some problems with this that existed in mariabackup utility (which were associated with incorrect handling of the innodb_data_dir parameter in some scenarios). In addition, this commit contains the following enhancements: 1) Added tests for mtr, which check the correct work with binlogs after SST (using rsync and mariabackup); 2) Added correct handling of slashes at the end of all paths that the SST script receives as parameters; 3) Improved parsing code for --mysqld-args parameters. Now it correctly processes the sequence "--" after the name of the one-letter option; 4) Checking the secret signature during joiner authentication is made independent of presence of bash (as a unix shell) in the system and diff utility no longer needed to check certificates compliance; 5) All directories that are necessary for the correct placement of various logs are automatically created by SST scripts in advance (before running mariabackup on the joiner node); 6) Removal of old binary logs on joiner is done using the binlog index (if it exists) (not only by fixed pattern that based on the current binlog name, as before); 7) Paths for placing binary logs are correctly processed if they are set as relative paths (to the datadir); 8) SST scripts are made even more resistant to spaces in filenames (now for binlogs); 9) In case of failure, SST scripts now always end with an exit code other than zero; 10) SST script for rsync now correctly create a tar file with the binlogs, even if the paths to them (in the binlog index file) are specified as a mix of absolute and relative paths, and even if they do not match with the datadir path specified in the current configuration settings.

MDEV-24962: Galera SST innobackupex-move ignores Environment settings After switching to the new mariabackup interface (instead of the outdated innobackupex interface, which is supported for compatibility), we need to explicitly pass a path to the datadir directory as a parameter, since in the new interface the value of this option is not automatically set in such a way that it always matches the SST/IST logic. This commit adds passing this option as an explicit parameter to mariabackup. This commit also removed unnecessary options that are not used and not supported by mariabackup. Also, numerous flaws in the common wsrep_sst_common script have been fixed: 1) There are many bash-specific constructs in the script that may not be supported by other interpreters, which can lead to the most unexpected errors during SST, because failures in the interpretation of bash-specific constructs lead to incorrect parsing of arguments; 2) There is parse_cnf() function which is often called by other scripts for the "mysqld" or "--mysqld" group, but it does not take into account the default group suffix, which leads to reading values only from the default group, which then leads to errors due to reading the default values instead of the values for a specific group; 3) Some options such as --user, --innodb-data-home-dir or --datadir are not removed from the --mysqld-args list, although they are processed inside scripts (and passing of these options funther may cause problems for mariabackup); 4) If an argument that the script understands is present in the --mysqld-args list twice, then this causes SST to fail, instead of reading the most recent value; 5) The "--host" parameter is technically still supported among the arguments of the SST scripts, but in reality scripts do not work with it as expected, especially if it has an IPv6 address; 6) If the port number is absent in the --address parameter value, but the port number is explicitly passed through the --port argument, then the scripts for mariabackup and xtrabackup-v2 fail; 7) If a new address interface is used (with the --address parameter), then automatic default port substitution is not performed, although it is supported for the legacy --host/--port interface. 8) If there are spaces in the parameter values after --mysqld_args, then their further transfer does not occur correctly, which causes mariabackup to fail during SST - the space splits the argument in such a way that it breaks the parsing of the following parameters; 9) If most of the parameters that are names or paths to the files or directories contain spaces, then SST scripts fail in an unpredictable way due to incorrect variable substitutions; 10) If the --log-bin option is passed among the arguments of myqlds (--mysqld-args) without a parameter, and the --binlog option is not specified, then the script cannot substitute the default name for binlog and cannot construct binlog name using the --log-basename argument (which is against server specifications); 11) Tail slashes are not removed from the directory names, which, upon further substitution, leads to the appearance of a double slash in the file paths; 12) The explicit --binlog parameter (which is now always transmitted from the server side) and the "hidden" --log-bin parameter in the list of arguments after --mysqld-args are perceived as two different parameters in different parts of the scripts, and if they are do not match for some reason, this will lead to failures during SST; Also, all new changes from the 10.6 branch have been migrated here, including the latest pull requests for authentication (only the part that concerns SST scripts). It also fixes dozens of other bugs in all SST scripts.

MDEV-25818: RSYNC SST failed due to busy port This commit reduces the likelihood of getting a busy port on quick restarts with rsync SST (problem MDEV-25818) and fixes a number of other flaws in SST scripts, adds new functionality, and also synchronizes the xtrabackup-v2 script with the mariabackup script (the latter applies only to the 10.2 branch): 1) SST via rsync: rsync and stunnel does not always get the right time to complete by correctly handling SIGTERM. These utilities are now given more time to complete normally (via normal SIGTERM processing) before we move on to using "kill -9"; 2) SST via rsync: attempts to terminate an rsync or stunnel process (via "kill" utility) are only made if it did not terminated on its own; 3) SST via rsync: if a combination of stunnel and rsync is used, then we need to wait for both utilities to finish or stop, not just one of them; 4) The config file and pid file for stunnel are now deleted after successful completion of SST on the donor node; 5) The configs and pid files from rsync and stunnel should not be deleted unless these utilities succeed (or are sucessfully terminated) on the joiner node; 6) The configs and pid files now excluded from transfer via rsync; 7) Spaces in paths are now valid for config files as well (when used with SST via rsync or mariabackup / xtrabackup[-v2]); 8) SST via mariabackup: added preliminary verification of keys and certificates that are used when establishing a connection using SSL (to avoid long timeouts and improve diagnostics) - by analogy with how it is done for the xtrabackup-v2 (plus check for CA file), while that check is skipped if the user does not have openssl installed (or does not have diff utility); 9) Added backup-threads=<n> configuration option which adds "--parallel=<n>" for mariabackup / xtrabackup at backup and move-back stages; 10) Added encrypt-threads and encrypt-chunk-size configuration options for xbcrypt management (when xbcrypt is used); 11) Small optimization: checking the socat version and adding a file with parameters for 2048-bit Diffie-Hellman (if necessary) is done only if the user has not specified "dhparam=" in the "sockopt" option value; 12) SST via rsync now supports "backup-threads" configuration option (in server-related sections or in the "[sst]"); 13) Determining the number of available processors is now supported for FreeBSD + mariabackup/xtrabackup: before that we might have problems with "--compact" (rebuild indexes) or qpress on FreeBSD; 14) The check_pid() function should not raise an error state in the rare cases when the pid file was created, but it is empty, or if it is deleted right during the check, or when zero is read from the pid file; 15) Iproved templates that are used to check if a requested socket is "listening" when using the ss utility; 16) Shortened some other templates for socket state utilities; 17) Temporary files created by mariabackup / xtrabackup are moved to a separate subdirectory inside tmpdir (so they don't get mixed with other temporary files, which can make debugging more difficult); 18) 10.2 only: the script for SST via xtrabackup-v2 has been brought in full compliance with all the bugfixes made for mariabackup (as it previously contained many flaws compared to the updated script for mariabackup).

MDEV-23580: WSREP_SST: [ERROR] rsync daemon port has been taken This commit contains a large set of further bug fixes and improvements to SST scripts for Galera, continuing the work that was started in MDEV-24962 to make SST scripts work smoothly in different network configurations (especially using ipv6) and with different environment settings: 1) The ipv6 addresses were incorrectly handled in the SST script for rsync (incorrect address substitution for establishing a connection, incorrect address substitution for bind, and so on); 2) Checking the locality of the ip-address in SST scripts did not support ipv6 addresses (such as "[::1]"), which were falsely identified as non-local ip, which further did not allow running two SSTs on different local addresses on the same machine. On the other hand, this bug masked some other errors (related to handling ipv6 addresses); 3) The code for checking the locality of the ip address was different in the SST scripts for rsync and for mysqldump, with individual flaws. This code is now made common and moved to wsrep_sst_common; 4) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) in the wait_for_listen() and check_pid_and_port() functions did not process ipv6 addresses correctly in all cases (not for all branches); 5) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) in the wait_for_listen() and check_pid_and_port() functions for some code branches could give a false positive result due to the textual match of prefixes in the port number and/or PID of the process; 6) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) was supported through different utilities in SST scripts for mariabackup and for rsync, and with various minor flaws in the code. Now the code is still different in these scripts, but it supports a common set of utilities (lsof, ss, sockstat) and is synchronized across patterns that used to check the output of these utilities; 7) In SST via mariabackup, the signal about readiness to receive data is sometimes sent too early - immediately after listen(), and not after accept() (which are called by socat or netcat utility). 8) Checking availability of the some options of some utilities was done using the grep pattern, which easily gives false positives; 9) Common name (CN) for local addresses, if not explicitly specified, is now always replaced to "localhost" to avoid the need to generate many separate certificates for local addresses of one machine and not to depend on which the local address is currently used in test (ipv4 or ipv6, etc.); 10) In tests galera_sst_mariabackup_encrypt_with_key_server and galera_sst_rsync_encrypt_with_key_server the correct certificate is selected to avoid commonname (CN) mismatch problems; 11) Further refactoring to protect against spaces in file names. 12) Further general refactoring to eliminate bash-specific constructs or to improve code readability; 13) The code for setting options for the nc (netcat) utility was different in different scripts for SST - now it is made identical. 14) Fixed long-time broken encryption via xbcrypt in combination with mariabackup and added support for key-based encryption via openssl utility, which is now enabled by default for encrypt=1 mode (this default mode can be changed using a new configuration file option "encypt-format=openssl|xbcrypt", which can be placed in the [mysqld], [sst] or in the [xtrabackup] section) - this change will allow us to use and to test the encypt=1 encryption without installing non-standard third-party utilities.

MDEV-27524: Incorrect binlogs after Galera SST using rsync and mariabackup This commit adds correct handling of binlogs for SST using rsync or mariabackup. Before this fix, binlogs were handled incorrectly - - only one (last) binary log file was transferred during SST, which then led to various failures (for example, when trying to list all events from the binary log). These bugs were long masked by flaws in the primitive binlogs handling code in the SST scripts, which causing binary logs files to be erased after transfer or not added to the binlog index on the joiner node. Now the correct transfer of all binary logs (not just the last of the binary log files) has been implemented both for the rsync (at the script level) and for the mariabackup (at the level of the main utility code). This commit also adds a new sst_max_binlogs=<n> parameter, which can be located in the [sst] section or in the [xtrabackup] section (historically, supported for mariabackup only, not for rsync), or in one of the server sections. This parameter specifies the number of binary log files to be sent to the joiner node during SST. This option is added for compatibility with old SST scripting behavior, which can be emulated by setting the sst_max_binlogs=1 (although in general this can cause problems for the reasons described above). In addition, setting the sst_max_binlogs=0 can be used to suppress the transmission of binary logs to the joiner nodes during SST (although sometimes a single file with the current binary log can still be transmitted to the joiner, even with sst_max_binlogs=0, because this sometimes necessary in modes that involve the use of GTIDs with Galera). Also, this commit ensures correct handling of paths to various innodb files and directories in the SST scripts, and fixes some problems with this that existed in mariabackup utility (which were associated with incorrect handling of the innodb_data_dir parameter in some scenarios). In addition, this commit contains the following enhancements: 1) Added tests for mtr, which check the correct work with binlogs after SST (using rsync and mariabackup); 2) Added correct handling of slashes at the end of all paths that the SST script receives as parameters; 3) Improved parsing code for --mysqld-args parameters. Now it correctly processes the sequence "--" after the name of the one-letter option; 4) Checking the secret signature during joiner authentication is made independent of presence of bash (as a unix shell) in the system and diff utility no longer needed to check certificates compliance; 5) All directories that are necessary for the correct placement of various logs are automatically created by SST scripts in advance (before running mariabackup on the joiner node); 6) Removal of old binary logs on joiner is done using the binlog index (if it exists) (not only by fixed pattern that based on the current binlog name, as before); 7) Paths for placing binary logs are correctly processed if they are set as relative paths (to the datadir); 8) SST scripts are made even more resistant to spaces in filenames (now for binlogs); 9) In case of failure, SST scripts now always end with an exit code other than zero; 10) SST script for rsync now correctly create a tar file with the binlogs, even if the paths to them (in the binlog index file) are specified as a mix of absolute and relative paths, and even if they do not match with the datadir path specified in the current configuration settings.

On the other hand, this bug masked some other errors (related to handling ipv6 addresses); 3) The code for checking the locality of the ip address was different in the SST scripts for rsync and for mysqldump, with individual flaws.

MDEV-24962: Galera SST innobackupex-move ignores Environment settings After switching to the new mariabackup interface (instead of the outdated innobackupex interface, which is supported for compatibility), we need to explicitly pass a path to the datadir directory as a parameter, since in the new interface the value of this option is not automatically set in such a way that it always matches the SST/IST logic. This commit adds passing this option as an explicit parameter to mariabackup. This commit also removed unnecessary options that are not used and not supported by mariabackup. Also, numerous flaws in the common wsrep_sst_common script have been fixed: 1) There are many bash-specific constructs in the script that may not be supported by other interpreters, which can lead to the most unexpected errors during SST, because failures in the interpretation of bash-specific constructs lead to incorrect parsing of arguments; 2) There is parse_cnf() function which is often called by other scripts for the "mysqld" or "--mysqld" group, but it does not take into account the default group suffix, which leads to reading values only from the default group, which then leads to errors due to reading the default values instead of the values for a specific group; 3) Some options such as --user, --innodb-data-home-dir or --datadir are not removed from the --mysqld-args list, although they are processed inside scripts (and passing of these options funther may cause problems for mariabackup); 4) If an argument that the script understands is present in the --mysqld-args list twice, then this causes SST to fail, instead of reading the most recent value; 5) The "--host" parameter is technically still supported among the arguments of the SST scripts, but in reality scripts do not work with it as expected, especially if it has an IPv6 address; 6) If the port number is absent in the --address parameter value, but the port number is explicitly passed through the --port argument, then the scripts for mariabackup and xtrabackup-v2 fail; 7) If a new address interface is used (with the --address parameter), then automatic default port substitution is not performed, although it is supported for the legacy --host/--port interface. 8) If there are spaces in the parameter values after --mysqld_args, then their further transfer does not occur correctly, which causes mariabackup to fail during SST - the space splits the argument in such a way that it breaks the parsing of the following parameters; 9) If most of the parameters that are names or paths to the files or directories contain spaces, then SST scripts fail in an unpredictable way due to incorrect variable substitutions; 10) If the --log-bin option is passed among the arguments of myqlds (--mysqld-args) without a parameter, and the --binlog option is not specified, then the script cannot substitute the default name for binlog and cannot construct binlog name using the --log-basename argument (which is against server specifications); 11) Tail slashes are not removed from the directory names, which, upon further substitution, leads to the appearance of a double slash in the file paths; 12) The explicit --binlog parameter (which is now always transmitted from the server side) and the "hidden" --log-bin parameter in the list of arguments after --mysqld-args are perceived as two different parameters in different parts of the scripts, and if they are do not match for some reason, this will lead to failures during SST; Also, all new changes from the 10.6 branch have been migrated here, including the latest pull requests for authentication (only the part that concerns SST scripts). It also fixes dozens of other bugs in all SST scripts.

This code is now made common and moved to wsrep_sst_common; 4) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) in the wait_for_listen() and check_pid_and_port() functions did not process ipv6 addresses correctly in all cases (not for all branches); 5) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) in the wait_for_listen() and check_pid_and_port() functions for some code branches could give a false positive result due to the textual match of prefixes in the port number and/or PID of the process; 6) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) was supported through different utilities in SST scripts for mariabackup and for rsync, and with various minor flaws in the code. Now the code is still different in these scripts, but it supports a common set of utilities (lsof, ss, sockstat) and is synchronized across patterns that used to check the output of these utilities; 7) In SST via mariabackup, the signal about readiness to receive data is sometimes sent too early - immediately after listen(), and not after accept() (which are called by socat or netcat utility). 8) Checking availability of the some options of some utilities was done using the grep pattern, which easily gives false positives; 9) Common name (CN) for local addresses, if not explicitly specified, is now always replaced to "localhost" to avoid the need to generate many separate certificates for local addresses of one machine and not to depend on which the local address is currently used in test (ipv4 or ipv6, etc.); 10) In tests galera_sst_mariabackup_encrypt_with_key_server and galera_sst_rsync_encrypt_with_key_server the correct certificate is selected to avoid commonname (CN) mismatch problems; 11) Further refactoring to protect against spaces in file names. 12) Further general refactoring to eliminate bash-specific constructs or to improve code readability; 13) The code for setting options for the nc (netcat) utility was different in different scripts for SST - now it is made identical. 14) Fixed long-time broken encryption via xbcrypt in combination with mariabackup and added support for key-based encryption via openssl utility, which is now enabled by default for encrypt=1 mode (this default mode can be changed using a new configuration file option "encypt-format=openssl|xbcrypt", which can be placed in the [mysqld], [sst] or in the [xtrabackup] section) - this change will allow us to use and to test the encypt=1 encryption without installing non-standard third-party utilities.

MDEV-27524: Incorrect binlogs after Galera SST using rsync and mariabackup This commit adds correct handling of binlogs for SST using rsync or mariabackup. Before this fix, binlogs were handled incorrectly - - only one (last) binary log file was transferred during SST, which then led to various failures (for example, when trying to list all events from the binary log). These bugs were long masked by flaws in the primitive binlogs handling code in the SST scripts, which causing binary logs files to be erased after transfer or not added to the binlog index on the joiner node. Now the correct transfer of all binary logs (not just the last of the binary log files) has been implemented both for the rsync (at the script level) and for the mariabackup (at the level of the main utility code). This commit also adds a new sst_max_binlogs=<n> parameter, which can be located in the [sst] section or in the [xtrabackup] section (historically, supported for mariabackup only, not for rsync), or in one of the server sections. This parameter specifies the number of binary log files to be sent to the joiner node during SST. This option is added for compatibility with old SST scripting behavior, which can be emulated by setting the sst_max_binlogs=1 (although in general this can cause problems for the reasons described above). In addition, setting the sst_max_binlogs=0 can be used to suppress the transmission of binary logs to the joiner nodes during SST (although sometimes a single file with the current binary log can still be transmitted to the joiner, even with sst_max_binlogs=0, because this sometimes necessary in modes that involve the use of GTIDs with Galera). Also, this commit ensures correct handling of paths to various innodb files and directories in the SST scripts, and fixes some problems with this that existed in mariabackup utility (which were associated with incorrect handling of the innodb_data_dir parameter in some scenarios). In addition, this commit contains the following enhancements: 1) Added tests for mtr, which check the correct work with binlogs after SST (using rsync and mariabackup); 2) Added correct handling of slashes at the end of all paths that the SST script receives as parameters; 3) Improved parsing code for --mysqld-args parameters. Now it correctly processes the sequence "--" after the name of the one-letter option; 4) Checking the secret signature during joiner authentication is made independent of presence of bash (as a unix shell) in the system and diff utility no longer needed to check certificates compliance; 5) All directories that are necessary for the correct placement of various logs are automatically created by SST scripts in advance (before running mariabackup on the joiner node); 6) Removal of old binary logs on joiner is done using the binlog index (if it exists) (not only by fixed pattern that based on the current binlog name, as before); 7) Paths for placing binary logs are correctly processed if they are set as relative paths (to the datadir); 8) SST scripts are made even more resistant to spaces in filenames (now for binlogs); 9) In case of failure, SST scripts now always end with an exit code other than zero; 10) SST script for rsync now correctly create a tar file with the binlogs, even if the paths to them (in the binlog index file) are specified as a mix of absolute and relative paths, and even if they do not match with the datadir path specified in the current configuration settings.

MDEV-25818: RSYNC SST failed due to busy port This commit reduces the likelihood of getting a busy port on quick restarts with rsync SST (problem MDEV-25818) and fixes a number of other flaws in SST scripts, adds new functionality, and also synchronizes the xtrabackup-v2 script with the mariabackup script (the latter applies only to the 10.2 branch): 1) SST via rsync: rsync and stunnel does not always get the right time to complete by correctly handling SIGTERM. These utilities are now given more time to complete normally (via normal SIGTERM processing) before we move on to using "kill -9"; 2) SST via rsync: attempts to terminate an rsync or stunnel process (via "kill" utility) are only made if it did not terminated on its own; 3) SST via rsync: if a combination of stunnel and rsync is used, then we need to wait for both utilities to finish or stop, not just one of them; 4) The config file and pid file for stunnel are now deleted after successful completion of SST on the donor node; 5) The configs and pid files from rsync and stunnel should not be deleted unless these utilities succeed (or are sucessfully terminated) on the joiner node; 6) The configs and pid files now excluded from transfer via rsync; 7) Spaces in paths are now valid for config files as well (when used with SST via rsync or mariabackup / xtrabackup[-v2]); 8) SST via mariabackup: added preliminary verification of keys and certificates that are used when establishing a connection using SSL (to avoid long timeouts and improve diagnostics) - by analogy with how it is done for the xtrabackup-v2 (plus check for CA file), while that check is skipped if the user does not have openssl installed (or does not have diff utility); 9) Added backup-threads=<n> configuration option which adds "--parallel=<n>" for mariabackup / xtrabackup at backup and move-back stages; 10) Added encrypt-threads and encrypt-chunk-size configuration options for xbcrypt management (when xbcrypt is used); 11) Small optimization: checking the socat version and adding a file with parameters for 2048-bit Diffie-Hellman (if necessary) is done only if the user has not specified "dhparam=" in the "sockopt" option value; 12) SST via rsync now supports "backup-threads" configuration option (in server-related sections or in the "[sst]"); 13) Determining the number of available processors is now supported for FreeBSD + mariabackup/xtrabackup: before that we might have problems with "--compact" (rebuild indexes) or qpress on FreeBSD; 14) The check_pid() function should not raise an error state in the rare cases when the pid file was created, but it is empty, or if it is deleted right during the check, or when zero is read from the pid file; 15) Iproved templates that are used to check if a requested socket is "listening" when using the ss utility; 16) Shortened some other templates for socket state utilities; 17) Temporary files created by mariabackup / xtrabackup are moved to a separate subdirectory inside tmpdir (so they don't get mixed with other temporary files, which can make debugging more difficult); 18) 10.2 only: the script for SST via xtrabackup-v2 has been brought in full compliance with all the bugfixes made for mariabackup (as it previously contained many flaws compared to the updated script for mariabackup).

Now it correctly processes the sequence "--" after the name of the one-letter option; 4) Checking the secret signature during joiner authentication is made independent of presence of bash (as a unix shell) in the system and diff utility no longer needed to check certificates compliance; 5) All directories that are necessary for the correct placement of various logs are automatically created by SST scripts in advance (before running mariabackup on the joiner node); 6) Removal of old binary logs on joiner is done using the binlog index (if it exists) (not only by fixed pattern that based on the current binlog name, as before); 7) Paths for placing binary logs are correctly processed if they are set as relative paths (to the datadir); 8) SST scripts are made even more resistant to spaces in filenames (now for binlogs); 9) In case of failure, SST scripts now always end with an exit code other than zero; 10) SST script for rsync now correctly create a tar file with the binlogs, even if the paths to them (in the binlog index file) are specified as a mix of absolute and relative paths, and even if they do not match with the datadir path specified in the current configuration settings.

MDEV-23580: WSREP_SST: [ERROR] rsync daemon port has been taken This commit contains a large set of further bug fixes and improvements to SST scripts for Galera, continuing the work that was started in MDEV-24962 to make SST scripts work smoothly in different network configurations (especially using ipv6) and with different environment settings: 1) The ipv6 addresses were incorrectly handled in the SST script for rsync (incorrect address substitution for establishing a connection, incorrect address substitution for bind, and so on); 2) Checking the locality of the ip-address in SST scripts did not support ipv6 addresses (such as "[::1]"), which were falsely identified as non-local ip, which further did not allow running two SSTs on different local addresses on the same machine. On the other hand, this bug masked some other errors (related to handling ipv6 addresses); 3) The code for checking the locality of the ip address was different in the SST scripts for rsync and for mysqldump, with individual flaws. This code is now made common and moved to wsrep_sst_common; 4) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) in the wait_for_listen() and check_pid_and_port() functions did not process ipv6 addresses correctly in all cases (not for all branches); 5) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) in the wait_for_listen() and check_pid_and_port() functions for some code branches could give a false positive result due to the textual match of prefixes in the port number and/or PID of the process; 6) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) was supported through different utilities in SST scripts for mariabackup and for rsync, and with various minor flaws in the code. Now the code is still different in these scripts, but it supports a common set of utilities (lsof, ss, sockstat) and is synchronized across patterns that used to check the output of these utilities; 7) In SST via mariabackup, the signal about readiness to receive data is sometimes sent too early - immediately after listen(), and not after accept() (which are called by socat or netcat utility). 8) Checking availability of the some options of some utilities was done using the grep pattern, which easily gives false positives; 9) Common name (CN) for local addresses, if not explicitly specified, is now always replaced to "localhost" to avoid the need to generate many separate certificates for local addresses of one machine and not to depend on which the local address is currently used in test (ipv4 or ipv6, etc.); 10) In tests galera_sst_mariabackup_encrypt_with_key_server and galera_sst_rsync_encrypt_with_key_server the correct certificate is selected to avoid commonname (CN) mismatch problems; 11) Further refactoring to protect against spaces in file names. 12) Further general refactoring to eliminate bash-specific constructs or to improve code readability; 13) The code for setting options for the nc (netcat) utility was different in different scripts for SST - now it is made identical. 14) Fixed long-time broken encryption via xbcrypt in combination with mariabackup and added support for key-based encryption via openssl utility, which is now enabled by default for encrypt=1 mode (this default mode can be changed using a new configuration file option "encypt-format=openssl|xbcrypt", which can be placed in the [mysqld], [sst] or in the [xtrabackup] section) - this change will allow us to use and to test the encypt=1 encryption without installing non-standard third-party utilities.

MDEV-27524: Incorrect binlogs after Galera SST using rsync and mariabackup This commit adds correct handling of binlogs for SST using rsync or mariabackup. Before this fix, binlogs were handled incorrectly - - only one (last) binary log file was transferred during SST, which then led to various failures (for example, when trying to list all events from the binary log). These bugs were long masked by flaws in the primitive binlogs handling code in the SST scripts, which causing binary logs files to be erased after transfer or not added to the binlog index on the joiner node. Now the correct transfer of all binary logs (not just the last of the binary log files) has been implemented both for the rsync (at the script level) and for the mariabackup (at the level of the main utility code). This commit also adds a new sst_max_binlogs=<n> parameter, which can be located in the [sst] section or in the [xtrabackup] section (historically, supported for mariabackup only, not for rsync), or in one of the server sections. This parameter specifies the number of binary log files to be sent to the joiner node during SST. This option is added for compatibility with old SST scripting behavior, which can be emulated by setting the sst_max_binlogs=1 (although in general this can cause problems for the reasons described above). In addition, setting the sst_max_binlogs=0 can be used to suppress the transmission of binary logs to the joiner nodes during SST (although sometimes a single file with the current binary log can still be transmitted to the joiner, even with sst_max_binlogs=0, because this sometimes necessary in modes that involve the use of GTIDs with Galera). Also, this commit ensures correct handling of paths to various innodb files and directories in the SST scripts, and fixes some problems with this that existed in mariabackup utility (which were associated with incorrect handling of the innodb_data_dir parameter in some scenarios). In addition, this commit contains the following enhancements: 1) Added tests for mtr, which check the correct work with binlogs after SST (using rsync and mariabackup); 2) Added correct handling of slashes at the end of all paths that the SST script receives as parameters; 3) Improved parsing code for --mysqld-args parameters.

MDEV-24962: Galera SST innobackupex-move ignores Environment settings After switching to the new mariabackup interface (instead of the outdated innobackupex interface, which is supported for compatibility), we need to explicitly pass a path to the datadir directory as a parameter, since in the new interface the value of this option is not automatically set in such a way that it always matches the SST/IST logic. This commit adds passing this option as an explicit parameter to mariabackup. This commit also removed unnecessary options that are not used and not supported by mariabackup. Also, numerous flaws in the common wsrep_sst_common script have been fixed: 1) There are many bash-specific constructs in the script that may not be supported by other interpreters, which can lead to the most unexpected errors during SST, because failures in the interpretation of bash-specific constructs lead to incorrect parsing of arguments; 2) There is parse_cnf() function which is often called by other scripts for the "mysqld" or "--mysqld" group, but it does not take into account the default group suffix, which leads to reading values only from the default group, which then leads to errors due to reading the default values instead of the values for a specific group; 3) Some options such as --user, --innodb-data-home-dir or --datadir are not removed from the --mysqld-args list, although they are processed inside scripts (and passing of these options funther may cause problems for mariabackup); 4) If an argument that the script understands is present in the --mysqld-args list twice, then this causes SST to fail, instead of reading the most recent value; 5) The "--host" parameter is technically still supported among the arguments of the SST scripts, but in reality scripts do not work with it as expected, especially if it has an IPv6 address; 6) If the port number is absent in the --address parameter value, but the port number is explicitly passed through the --port argument, then the scripts for mariabackup and xtrabackup-v2 fail; 7) If a new address interface is used (with the --address parameter), then automatic default port substitution is not performed, although it is supported for the legacy --host/--port interface. 8) If there are spaces in the parameter values after --mysqld_args, then their further transfer does not occur correctly, which causes mariabackup to fail during SST - the space splits the argument in such a way that it breaks the parsing of the following parameters; 9) If most of the parameters that are names or paths to the files or directories contain spaces, then SST scripts fail in an unpredictable way due to incorrect variable substitutions; 10) If the --log-bin option is passed among the arguments of myqlds (--mysqld-args) without a parameter, and the --binlog option is not specified, then the script cannot substitute the default name for binlog and cannot construct binlog name using the --log-basename argument (which is against server specifications); 11) Tail slashes are not removed from the directory names, which, upon further substitution, leads to the appearance of a double slash in the file paths; 12) The explicit --binlog parameter (which is now always transmitted from the server side) and the "hidden" --log-bin parameter in the list of arguments after --mysqld-args are perceived as two different parameters in different parts of the scripts, and if they are do not match for some reason, this will lead to failures during SST; Also, all new changes from the 10.6 branch have been migrated here, including the latest pull requests for authentication (only the part that concerns SST scripts). It also fixes dozens of other bugs in all SST scripts.

MDEV-21770: `galera_3nodes.galera_ipv6_mariabackup` fails This patch fixes several flaws in the SST scripts that cause failures while running tests that use version 6 IP addresses for cluster nodes. First, if the netcat utility is used for streaming (but not socat), then in accordance with its command line syntax, we need to remove the square brackets around the IPv6 address. However, for socat, the address must contain square brackets, as before. Secondly, if an IPv6 address is used, then from the joiner side for a number of systems (such as Debian) we need to explicitly specify the "-6" option, otherwise a listening socket with an IPv6 address may not be created. This patch also contains code improvements in the wsrep_sst_common. Changed the code that pars the connection address - fixed the shortcomings that sometimes led to incorrect parsing of parameters when using shells other than the latest versions of bash. Also, this patch removes the duplicate code that is intended for parsing the connection address and which was located in the wsrep_sst_mariabackup file, since all the necessary actions have already been done in wsrep_sst_common and there they are done in such a way that any shell is supported, not just bash. The fix does not require separate tests, since all the necessary tests are already present in the galera_3nodes suite. On the contrary, after this fix, tests using IPv6 addresses can be removed from the disabled list (this will be done in a separate commit related to MDEV-23659).

This code is now made common and moved to wsrep_sst_common; 4) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) in the wait_for_listen() and check_pid_and_port() functions did not process ipv6 addresses correctly in all cases (not for all branches); 5) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) in the wait_for_listen() and check_pid_and_port() functions for some code branches could give a false positive result due to the textual match of prefixes in the port number and/or PID of the process; 6) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) was supported through different utilities in SST scripts for mariabackup and for rsync, and with various minor flaws in the code. Now the code is still different in these scripts, but it supports a common set of utilities (lsof, ss, sockstat) and is synchronized across patterns that used to check the output of these utilities; 7) In SST via mariabackup, the signal about readiness to receive data is sometimes sent too early - immediately after listen(), and not after accept() (which are called by socat or netcat utility). 8) Checking availability of the some options of some utilities was done using the grep pattern, which easily gives false positives; 9) Common name (CN) for local addresses, if not explicitly specified, is now always replaced to "localhost" to avoid the need to generate many separate certificates for local addresses of one machine and not to depend on which the local address is currently used in test (ipv4 or ipv6, etc.); 10) In tests galera_sst_mariabackup_encrypt_with_key_server and galera_sst_rsync_encrypt_with_key_server the correct certificate is selected to avoid commonname (CN) mismatch problems; 11) Further refactoring to protect against spaces in file names. 12) Further general refactoring to eliminate bash-specific constructs or to improve code readability; 13) The code for setting options for the nc (netcat) utility was different in different scripts for SST - now it is made identical. 14) Fixed long-time broken encryption via xbcrypt in combination with mariabackup and added support for key-based encryption via openssl utility, which is now enabled by default for encrypt=1 mode (this default mode can be changed using a new configuration file option "encypt-format=openssl|xbcrypt", which can be placed in the [mysqld], [sst] or in the [xtrabackup] section) - this change will allow us to use and to test the encypt=1 encryption without installing non-standard third-party utilities.

MDEV-21770: `galera_3nodes.galera_ipv6_mariabackup` fails This patch fixes several flaws in the SST scripts that cause failures while running tests that use version 6 IP addresses for cluster nodes. First, if the netcat utility is used for streaming (but not socat), then in accordance with its command line syntax, we need to remove the square brackets around the IPv6 address. However, for socat, the address must contain square brackets, as before. Secondly, if an IPv6 address is used, then from the joiner side for a number of systems (such as Debian) we need to explicitly specify the "-6" option, otherwise a listening socket with an IPv6 address may not be created. This patch also contains code improvements in the wsrep_sst_common. Changed the code that pars the connection address - fixed the shortcomings that sometimes led to incorrect parsing of parameters when using shells other than the latest versions of bash. Also, this patch removes the duplicate code that is intended for parsing the connection address and which was located in the wsrep_sst_mariabackup file, since all the necessary actions have already been done in wsrep_sst_common and there they are done in such a way that any shell is supported, not just bash. The fix does not require separate tests, since all the necessary tests are already present in the galera_3nodes suite. On the contrary, after this fix, tests using IPv6 addresses can be removed from the disabled list (this will be done in a separate commit related to MDEV-23659).

MDEV-27524: Incorrect binlogs after Galera SST using rsync and mariabackup This commit adds correct handling of binlogs for SST using rsync or mariabackup. Before this fix, binlogs were handled incorrectly - - only one (last) binary log file was transferred during SST, which then led to various failures (for example, when trying to list all events from the binary log). These bugs were long masked by flaws in the primitive binlogs handling code in the SST scripts, which causing binary logs files to be erased after transfer or not added to the binlog index on the joiner node. Now the correct transfer of all binary logs (not just the last of the binary log files) has been implemented both for the rsync (at the script level) and for the mariabackup (at the level of the main utility code). This commit also adds a new sst_max_binlogs=<n> parameter, which can be located in the [sst] section or in the [xtrabackup] section (historically, supported for mariabackup only, not for rsync), or in one of the server sections. This parameter specifies the number of binary log files to be sent to the joiner node during SST. This option is added for compatibility with old SST scripting behavior, which can be emulated by setting the sst_max_binlogs=1 (although in general this can cause problems for the reasons described above). In addition, setting the sst_max_binlogs=0 can be used to suppress the transmission of binary logs to the joiner nodes during SST (although sometimes a single file with the current binary log can still be transmitted to the joiner, even with sst_max_binlogs=0, because this sometimes necessary in modes that involve the use of GTIDs with Galera). Also, this commit ensures correct handling of paths to various innodb files and directories in the SST scripts, and fixes some problems with this that existed in mariabackup utility (which were associated with incorrect handling of the innodb_data_dir parameter in some scenarios). In addition, this commit contains the following enhancements: 1) Added tests for mtr, which check the correct work with binlogs after SST (using rsync and mariabackup); 2) Added correct handling of slashes at the end of all paths that the SST script receives as parameters; 3) Improved parsing code for --mysqld-args parameters. Now it correctly processes the sequence "--" after the name of the one-letter option; 4) Checking the secret signature during joiner authentication is made independent of presence of bash (as a unix shell) in the system and diff utility no longer needed to check certificates compliance; 5) All directories that are necessary for the correct placement of various logs are automatically created by SST scripts in advance (before running mariabackup on the joiner node); 6) Removal of old binary logs on joiner is done using the binlog index (if it exists) (not only by fixed pattern that based on the current binlog name, as before); 7) Paths for placing binary logs are correctly processed if they are set as relative paths (to the datadir); 8) SST scripts are made even more resistant to spaces in filenames (now for binlogs); 9) In case of failure, SST scripts now always end with an exit code other than zero; 10) SST script for rsync now correctly create a tar file with the binlogs, even if the paths to them (in the binlog index file) are specified as a mix of absolute and relative paths, and even if they do not match with the datadir path specified in the current configuration settings.

MDEV-25818: RSYNC SST failed due to busy port This commit reduces the likelihood of getting a busy port on quick restarts with rsync SST (problem MDEV-25818) and fixes a number of other flaws in SST scripts, adds new functionality, and also synchronizes the xtrabackup-v2 script with the mariabackup script (the latter applies only to the 10.2 branch): 1) SST via rsync: rsync and stunnel does not always get the right time to complete by correctly handling SIGTERM. These utilities are now given more time to complete normally (via normal SIGTERM processing) before we move on to using "kill -9"; 2) SST via rsync: attempts to terminate an rsync or stunnel process (via "kill" utility) are only made if it did not terminated on its own; 3) SST via rsync: if a combination of stunnel and rsync is used, then we need to wait for both utilities to finish or stop, not just one of them; 4) The config file and pid file for stunnel are now deleted after successful completion of SST on the donor node; 5) The configs and pid files from rsync and stunnel should not be deleted unless these utilities succeed (or are sucessfully terminated) on the joiner node; 6) The configs and pid files now excluded from transfer via rsync; 7) Spaces in paths are now valid for config files as well (when used with SST via rsync or mariabackup / xtrabackup[-v2]); 8) SST via mariabackup: added preliminary verification of keys and certificates that are used when establishing a connection using SSL (to avoid long timeouts and improve diagnostics) - by analogy with how it is done for the xtrabackup-v2 (plus check for CA file), while that check is skipped if the user does not have openssl installed (or does not have diff utility); 9) Added backup-threads=<n> configuration option which adds "--parallel=<n>" for mariabackup / xtrabackup at backup and move-back stages; 10) Added encrypt-threads and encrypt-chunk-size configuration options for xbcrypt management (when xbcrypt is used); 11) Small optimization: checking the socat version and adding a file with parameters for 2048-bit Diffie-Hellman (if necessary) is done only if the user has not specified "dhparam=" in the "sockopt" option value; 12) SST via rsync now supports "backup-threads" configuration option (in server-related sections or in the "[sst]"); 13) Determining the number of available processors is now supported for FreeBSD + mariabackup/xtrabackup: before that we might have problems with "--compact" (rebuild indexes) or qpress on FreeBSD; 14) The check_pid() function should not raise an error state in the rare cases when the pid file was created, but it is empty, or if it is deleted right during the check, or when zero is read from the pid file; 15) Iproved templates that are used to check if a requested socket is "listening" when using the ss utility; 16) Shortened some other templates for socket state utilities; 17) Temporary files created by mariabackup / xtrabackup are moved to a separate subdirectory inside tmpdir (so they don't get mixed with other temporary files, which can make debugging more difficult); 18) 10.2 only: the script for SST via xtrabackup-v2 has been brought in full compliance with all the bugfixes made for mariabackup (as it previously contained many flaws compared to the updated script for mariabackup).

MDEV-24962: Galera SST innobackupex-move ignores Environment settings After switching to the new mariabackup interface (instead of the outdated innobackupex interface, which is supported for compatibility), we need to explicitly pass a path to the datadir directory as a parameter, since in the new interface the value of this option is not automatically set in such a way that it always matches the SST/IST logic. This commit adds passing this option as an explicit parameter to mariabackup. This commit also removed unnecessary options that are not used and not supported by mariabackup. Also, numerous flaws in the common wsrep_sst_common script have been fixed: 1) There are many bash-specific constructs in the script that may not be supported by other interpreters, which can lead to the most unexpected errors during SST, because failures in the interpretation of bash-specific constructs lead to incorrect parsing of arguments; 2) There is parse_cnf() function which is often called by other scripts for the "mysqld" or "--mysqld" group, but it does not take into account the default group suffix, which leads to reading values only from the default group, which then leads to errors due to reading the default values instead of the values for a specific group; 3) Some options such as --user, --innodb-data-home-dir or --datadir are not removed from the --mysqld-args list, although they are processed inside scripts (and passing of these options funther may cause problems for mariabackup); 4) If an argument that the script understands is present in the --mysqld-args list twice, then this causes SST to fail, instead of reading the most recent value; 5) The "--host" parameter is technically still supported among the arguments of the SST scripts, but in reality scripts do not work with it as expected, especially if it has an IPv6 address; 6) If the port number is absent in the --address parameter value, but the port number is explicitly passed through the --port argument, then the scripts for mariabackup and xtrabackup-v2 fail; 7) If a new address interface is used (with the --address parameter), then automatic default port substitution is not performed, although it is supported for the legacy --host/--port interface. 8) If there are spaces in the parameter values after --mysqld_args, then their further transfer does not occur correctly, which causes mariabackup to fail during SST - the space splits the argument in such a way that it breaks the parsing of the following parameters; 9) If most of the parameters that are names or paths to the files or directories contain spaces, then SST scripts fail in an unpredictable way due to incorrect variable substitutions; 10) If the --log-bin option is passed among the arguments of myqlds (--mysqld-args) without a parameter, and the --binlog option is not specified, then the script cannot substitute the default name for binlog and cannot construct binlog name using the --log-basename argument (which is against server specifications); 11) Tail slashes are not removed from the directory names, which, upon further substitution, leads to the appearance of a double slash in the file paths; 12) The explicit --binlog parameter (which is now always transmitted from the server side) and the "hidden" --log-bin parameter in the list of arguments after --mysqld-args are perceived as two different parameters in different parts of the scripts, and if they are do not match for some reason, this will lead to failures during SST; Also, all new changes from the 10.6 branch have been migrated here, including the latest pull requests for authentication (only the part that concerns SST scripts). It also fixes dozens of other bugs in all SST scripts.

On the other hand, this bug masked some other errors (related to handling ipv6 addresses); 3) The code for checking the locality of the ip address was different in the SST scripts for rsync and for mysqldump, with individual flaws. This code is now made common and moved to wsrep_sst_common; 4) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) in the wait_for_listen() and check_pid_and_port() functions did not process ipv6 addresses correctly in all cases (not for all branches); 5) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) in the wait_for_listen() and check_pid_and_port() functions for some code branches could give a false positive result due to the textual match of prefixes in the port number and/or PID of the process; 6) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) was supported through different utilities in SST scripts for mariabackup and for rsync, and with various minor flaws in the code. Now the code is still different in these scripts, but it supports a common set of utilities (lsof, ss, sockstat) and is synchronized across patterns that used to check the output of these utilities; 7) In SST via mariabackup, the signal about readiness to receive data is sometimes sent too early - immediately after listen(), and not after accept() (which are called by socat or netcat utility). 8) Checking availability of the some options of some utilities was done using the grep pattern, which easily gives false positives; 9) Common name (CN) for local addresses, if not explicitly specified, is now always replaced to "localhost" to avoid the need to generate many separate certificates for local addresses of one machine and not to depend on which the local address is currently used in test (ipv4 or ipv6, etc.); 10) In tests galera_sst_mariabackup_encrypt_with_key_server and galera_sst_rsync_encrypt_with_key_server the correct certificate is selected to avoid commonname (CN) mismatch problems; 11) Further refactoring to protect against spaces in file names. 12) Further general refactoring to eliminate bash-specific constructs or to improve code readability; 13) The code for setting options for the nc (netcat) utility was different in different scripts for SST - now it is made identical. 14) Fixed long-time broken encryption via xbcrypt in combination with mariabackup and added support for key-based encryption via openssl utility, which is now enabled by default for encrypt=1 mode (this default mode can be changed using a new configuration file option "encypt-format=openssl|xbcrypt", which can be placed in the [mysqld], [sst] or in the [xtrabackup] section) - this change will allow us to use and to test the encypt=1 encryption without installing non-standard third-party utilities.

Also, numerous flaws in the common wsrep_sst_common script have been fixed: 1) There are many bash-specific constructs in the script that may not be supported by other interpreters, which can lead to the most unexpected errors during SST, because failures in the interpretation of bash-specific constructs lead to incorrect parsing of arguments; 2) There is parse_cnf() function which is often called by other scripts for the "mysqld" or "--mysqld" group, but it does not take into account the default group suffix, which leads to reading values only from the default group, which then leads to errors due to reading the default values instead of the values for a specific group; 3) Some options such as --user, --innodb-data-home-dir or --datadir are not removed from the --mysqld-args list, although they are processed inside scripts (and passing of these options funther may cause problems for mariabackup); 4) If an argument that the script understands is present in the --mysqld-args list twice, then this causes SST to fail, instead of reading the most recent value; 5) The "--host" parameter is technically still supported among the arguments of the SST scripts, but in reality scripts do not work with it as expected, especially if it has an IPv6 address; 6) If the port number is absent in the --address parameter value, but the port number is explicitly passed through the --port argument, then the scripts for mariabackup and xtrabackup-v2 fail; 7) If a new address interface is used (with the --address parameter), then automatic default port substitution is not performed, although it is supported for the legacy --host/--port interface. 8) If there are spaces in the parameter values after --mysqld_args, then their further transfer does not occur correctly, which causes mariabackup to fail during SST - the space splits the argument in such a way that it breaks the parsing of the following parameters; 9) If most of the parameters that are names or paths to the files or directories contain spaces, then SST scripts fail in an unpredictable way due to incorrect variable substitutions; 10) If the --log-bin option is passed among the arguments of myqlds (--mysqld-args) without a parameter, and the --binlog option is not specified, then the script cannot substitute the default name for binlog and cannot construct binlog name using the --log-basename argument (which is against server specifications); 11) Tail slashes are not removed from the directory names, which, upon further substitution, leads to the appearance of a double slash in the file paths; 12) The explicit --binlog parameter (which is now always transmitted from the server side) and the "hidden" --log-bin parameter in the list of arguments after --mysqld-args are perceived as two different parameters in different parts of the scripts, and if they are do not match for some reason, this will lead to failures during SST; Also, all new changes from the 10.6 branch have been migrated here, including the latest pull requests for authentication (only the part that concerns SST scripts). It also fixes dozens of other bugs in all SST scripts.

MDEV-25818: RSYNC SST failed due to busy port This commit reduces the likelihood of getting a busy port on quick restarts with rsync SST (problem MDEV-25818) and fixes a number of other flaws in SST scripts, adds new functionality, and also synchronizes the xtrabackup-v2 script with the mariabackup script (the latter applies only to the 10.2 branch): 1) SST via rsync: rsync and stunnel does not always get the right time to complete by correctly handling SIGTERM. These utilities are now given more time to complete normally (via normal SIGTERM processing) before we move on to using "kill -9"; 2) SST via rsync: attempts to terminate an rsync or stunnel process (via "kill" utility) are only made if it did not terminated on its own; 3) SST via rsync: if a combination of stunnel and rsync is used, then we need to wait for both utilities to finish or stop, not just one of them; 4) The config file and pid file for stunnel are now deleted after successful completion of SST on the donor node; 5) The configs and pid files from rsync and stunnel should not be deleted unless these utilities succeed (or are sucessfully terminated) on the joiner node; 6) The configs and pid files now excluded from transfer via rsync; 7) Spaces in paths are now valid for config files as well (when used with SST via rsync or mariabackup / xtrabackup[-v2]); 8) SST via mariabackup: added preliminary verification of keys and certificates that are used when establishing a connection using SSL (to avoid long timeouts and improve diagnostics) - by analogy with how it is done for the xtrabackup-v2 (plus check for CA file), while that check is skipped if the user does not have openssl installed (or does not have diff utility); 9) Added backup-threads=<n> configuration option which adds "--parallel=<n>" for mariabackup / xtrabackup at backup and move-back stages; 10) Added encrypt-threads and encrypt-chunk-size configuration options for xbcrypt management (when xbcrypt is used); 11) Small optimization: checking the socat version and adding a file with parameters for 2048-bit Diffie-Hellman (if necessary) is done only if the user has not specified "dhparam=" in the "sockopt" option value; 12) SST via rsync now supports "backup-threads" configuration option (in server-related sections or in the "[sst]"); 13) Determining the number of available processors is now supported for FreeBSD + mariabackup/xtrabackup: before that we might have problems with "--compact" (rebuild indexes) or qpress on FreeBSD; 14) The check_pid() function should not raise an error state in the rare cases when the pid file was created, but it is empty, or if it is deleted right during the check, or when zero is read from the pid file; 15) Iproved templates that are used to check if a requested socket is "listening" when using the ss utility; 16) Shortened some other templates for socket state utilities; 17) Temporary files created by mariabackup / xtrabackup are moved to a separate subdirectory inside tmpdir (so they don't get mixed with other temporary files, which can make debugging more difficult); 18) 10.2 only: the script for SST via xtrabackup-v2 has been brought in full compliance with all the bugfixes made for mariabackup (as it previously contained many flaws compared to the updated script for mariabackup).

MDEV-23580: WSREP_SST: [ERROR] rsync daemon port has been taken This commit contains a large set of further bug fixes and improvements to SST scripts for Galera, continuing the work that was started in MDEV-24962 to make SST scripts work smoothly in different network configurations (especially using ipv6) and with different environment settings: 1) The ipv6 addresses were incorrectly handled in the SST script for rsync (incorrect address substitution for establishing a connection, incorrect address substitution for bind, and so on); 2) Checking the locality of the ip-address in SST scripts did not support ipv6 addresses (such as "[::1]"), which were falsely identified as non-local ip, which further did not allow running two SSTs on different local addresses on the same machine. On the other hand, this bug masked some other errors (related to handling ipv6 addresses); 3) The code for checking the locality of the ip address was different in the SST scripts for rsync and for mysqldump, with individual flaws. This code is now made common and moved to wsrep_sst_common; 4) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) in the wait_for_listen() and check_pid_and_port() functions did not process ipv6 addresses correctly in all cases (not for all branches); 5) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) in the wait_for_listen() and check_pid_and_port() functions for some code branches could give a false positive result due to the textual match of prefixes in the port number and/or PID of the process; 6) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) was supported through different utilities in SST scripts for mariabackup and for rsync, and with various minor flaws in the code. Now the code is still different in these scripts, but it supports a common set of utilities (lsof, ss, sockstat) and is synchronized across patterns that used to check the output of these utilities; 7) In SST via mariabackup, the signal about readiness to receive data is sometimes sent too early - immediately after listen(), and not after accept() (which are called by socat or netcat utility). 8) Checking availability of the some options of some utilities was done using the grep pattern, which easily gives false positives; 9) Common name (CN) for local addresses, if not explicitly specified, is now always replaced to "localhost" to avoid the need to generate many separate certificates for local addresses of one machine and not to depend on which the local address is currently used in test (ipv4 or ipv6, etc.); 10) In tests galera_sst_mariabackup_encrypt_with_key_server and galera_sst_rsync_encrypt_with_key_server the correct certificate is selected to avoid commonname (CN) mismatch problems; 11) Further refactoring to protect against spaces in file names. 12) Further general refactoring to eliminate bash-specific constructs or to improve code readability; 13) The code for setting options for the nc (netcat) utility was different in different scripts for SST - now it is made identical. 14) Fixed long-time broken encryption via xbcrypt in combination with mariabackup and added support for key-based encryption via openssl utility, which is now enabled by default for encrypt=1 mode (this default mode can be changed using a new configuration file option "encypt-format=openssl|xbcrypt", which can be placed in the [mysqld], [sst] or in the [xtrabackup] section) - this change will allow us to use and to test the encypt=1 encryption without installing non-standard third-party utilities.

Also, numerous flaws in the common wsrep_sst_common script have been fixed: 1) There are many bash-specific constructs in the script that may not be supported by other interpreters, which can lead to the most unexpected errors during SST, because failures in the interpretation of bash-specific constructs lead to incorrect parsing of arguments; 2) There is parse_cnf() function which is often called by other scripts for the "mysqld" or "--mysqld" group, but it does not take into account the default group suffix, which leads to reading values only from the default group, which then leads to errors due to reading the default values instead of the values for a specific group; 3) Some options such as --user, --innodb-data-home-dir or --datadir are not removed from the --mysqld-args list, although they are processed inside scripts (and passing of these options funther may cause problems for mariabackup); 4) If an argument that the script understands is present in the --mysqld-args list twice, then this causes SST to fail, instead of reading the most recent value; 5) The "--host" parameter is technically still supported among the arguments of the SST scripts, but in reality scripts do not work with it as expected, especially if it has an IPv6 address; 6) If the port number is absent in the --address parameter value, but the port number is explicitly passed through the --port argument, then the scripts for mariabackup and xtrabackup-v2 fail; 7) If a new address interface is used (with the --address parameter), then automatic default port substitution is not performed, although it is supported for the legacy --host/--port interface. 8) If there are spaces in the parameter values after --mysqld_args, then their further transfer does not occur correctly, which causes mariabackup to fail during SST - the space splits the argument in such a way that it breaks the parsing of the following parameters; 9) If most of the parameters that are names or paths to the files or directories contain spaces, then SST scripts fail in an unpredictable way due to incorrect variable substitutions; 10) If the --log-bin option is passed among the arguments of myqlds (--mysqld-args) without a parameter, and the --binlog option is not specified, then the script cannot substitute the default name for binlog and cannot construct binlog name using the --log-basename argument (which is against server specifications); 11) Tail slashes are not removed from the directory names, which, upon further substitution, leads to the appearance of a double slash in the file paths; 12) The explicit --binlog parameter (which is now always transmitted from the server side) and the "hidden" --log-bin parameter in the list of arguments after --mysqld-args are perceived as two different parameters in different parts of the scripts, and if they are do not match for some reason, this will lead to failures during SST; Also, all new changes from the 10.6 branch have been migrated here, including the latest pull requests for authentication (only the part that concerns SST scripts). It also fixes dozens of other bugs in all SST scripts.

MDEV-23580: WSREP_SST: [ERROR] rsync daemon port has been taken This commit contains a large set of further bug fixes and improvements to SST scripts for Galera, continuing the work that was started in MDEV-24962 to make SST scripts work smoothly in different network configurations (especially using ipv6) and with different environment settings: 1) The ipv6 addresses were incorrectly handled in the SST script for rsync (incorrect address substitution for establishing a connection, incorrect address substitution for bind, and so on); 2) Checking the locality of the ip-address in SST scripts did not support ipv6 addresses (such as "[::1]"), which were falsely identified as non-local ip, which further did not allow running two SSTs on different local addresses on the same machine. On the other hand, this bug masked some other errors (related to handling ipv6 addresses); 3) The code for checking the locality of the ip address was different in the SST scripts for rsync and for mysqldump, with individual flaws. This code is now made common and moved to wsrep_sst_common; 4) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) in the wait_for_listen() and check_pid_and_port() functions did not process ipv6 addresses correctly in all cases (not for all branches); 5) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) in the wait_for_listen() and check_pid_and_port() functions for some code branches could give a false positive result due to the textual match of prefixes in the port number and/or PID of the process; 6) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) was supported through different utilities in SST scripts for mariabackup and for rsync, and with various minor flaws in the code. Now the code is still different in these scripts, but it supports a common set of utilities (lsof, ss, sockstat) and is synchronized across patterns that used to check the output of these utilities; 7) In SST via mariabackup, the signal about readiness to receive data is sometimes sent too early - immediately after listen(), and not after accept() (which are called by socat or netcat utility). 8) Checking availability of the some options of some utilities was done using the grep pattern, which easily gives false positives; 9) Common name (CN) for local addresses, if not explicitly specified, is now always replaced to "localhost" to avoid the need to generate many separate certificates for local addresses of one machine and not to depend on which the local address is currently used in test (ipv4 or ipv6, etc.); 10) In tests galera_sst_mariabackup_encrypt_with_key_server and galera_sst_rsync_encrypt_with_key_server the correct certificate is selected to avoid commonname (CN) mismatch problems; 11) Further refactoring to protect against spaces in file names. 12) Further general refactoring to eliminate bash-specific constructs or to improve code readability; 13) The code for setting options for the nc (netcat) utility was different in different scripts for SST - now it is made identical. 14) Fixed long-time broken encryption via xbcrypt in combination with mariabackup and added support for key-based encryption via openssl utility, which is now enabled by default for encrypt=1 mode (this default mode can be changed using a new configuration file option "encypt-format=openssl|xbcrypt", which can be placed in the [mysqld], [sst] or in the [xtrabackup] section) - this change will allow us to use and to test the encypt=1 encryption without installing non-standard third-party utilities.

MDEV-25818: RSYNC SST failed due to busy port This commit reduces the likelihood of getting a busy port on quick restarts with rsync SST (problem MDEV-25818) and fixes a number of other flaws in SST scripts, adds new functionality, and also synchronizes the xtrabackup-v2 script with the mariabackup script (the latter applies only to the 10.2 branch): 1) SST via rsync: rsync and stunnel does not always get the right time to complete by correctly handling SIGTERM. These utilities are now given more time to complete normally (via normal SIGTERM processing) before we move on to using "kill -9"; 2) SST via rsync: attempts to terminate an rsync or stunnel process (via "kill" utility) are only made if it did not terminated on its own; 3) SST via rsync: if a combination of stunnel and rsync is used, then we need to wait for both utilities to finish or stop, not just one of them; 4) The config file and pid file for stunnel are now deleted after successful completion of SST on the donor node; 5) The configs and pid files from rsync and stunnel should not be deleted unless these utilities succeed (or are sucessfully terminated) on the joiner node; 6) The configs and pid files now excluded from transfer via rsync; 7) Spaces in paths are now valid for config files as well (when used with SST via rsync or mariabackup / xtrabackup[-v2]); 8) SST via mariabackup: added preliminary verification of keys and certificates that are used when establishing a connection using SSL (to avoid long timeouts and improve diagnostics) - by analogy with how it is done for the xtrabackup-v2 (plus check for CA file), while that check is skipped if the user does not have openssl installed (or does not have diff utility); 9) Added backup-threads=<n> configuration option which adds "--parallel=<n>" for mariabackup / xtrabackup at backup and move-back stages; 10) Added encrypt-threads and encrypt-chunk-size configuration options for xbcrypt management (when xbcrypt is used); 11) Small optimization: checking the socat version and adding a file with parameters for 2048-bit Diffie-Hellman (if necessary) is done only if the user has not specified "dhparam=" in the "sockopt" option value; 12) SST via rsync now supports "backup-threads" configuration option (in server-related sections or in the "[sst]"); 13) Determining the number of available processors is now supported for FreeBSD + mariabackup/xtrabackup: before that we might have problems with "--compact" (rebuild indexes) or qpress on FreeBSD; 14) The check_pid() function should not raise an error state in the rare cases when the pid file was created, but it is empty, or if it is deleted right during the check, or when zero is read from the pid file; 15) Iproved templates that are used to check if a requested socket is "listening" when using the ss utility; 16) Shortened some other templates for socket state utilities; 17) Temporary files created by mariabackup / xtrabackup are moved to a separate subdirectory inside tmpdir (so they don't get mixed with other temporary files, which can make debugging more difficult); 18) 10.2 only: the script for SST via xtrabackup-v2 has been brought in full compliance with all the bugfixes made for mariabackup (as it previously contained many flaws compared to the updated script for mariabackup).

MDEV-24962: Galera SST innobackupex-move ignores Environment settings After switching to the new mariabackup interface (instead of the outdated innobackupex interface, which is supported for compatibility), we need to explicitly pass a path to the datadir directory as a parameter, since in the new interface the value of this option is not automatically set in such a way that it always matches the SST/IST logic. This commit adds passing this option as an explicit parameter to mariabackup. This commit also removed unnecessary options that are not used and not supported by mariabackup. Also, numerous flaws in the common wsrep_sst_common script have been fixed: 1) There are many bash-specific constructs in the script that may not be supported by other interpreters, which can lead to the most unexpected errors during SST, because failures in the interpretation of bash-specific constructs lead to incorrect parsing of arguments; 2) There is parse_cnf() function which is often called by other scripts for the "mysqld" or "--mysqld" group, but it does not take into account the default group suffix, which leads to reading values only from the default group, which then leads to errors due to reading the default values instead of the values for a specific group; 3) Some options such as --user, --innodb-data-home-dir or --datadir are not removed from the --mysqld-args list, although they are processed inside scripts (and passing of these options funther may cause problems for mariabackup); 4) If an argument that the script understands is present in the --mysqld-args list twice, then this causes SST to fail, instead of reading the most recent value; 5) The "--host" parameter is technically still supported among the arguments of the SST scripts, but in reality scripts do not work with it as expected, especially if it has an IPv6 address; 6) If the port number is absent in the --address parameter value, but the port number is explicitly passed through the --port argument, then the scripts for mariabackup and xtrabackup-v2 fail; 7) If a new address interface is used (with the --address parameter), then automatic default port substitution is not performed, although it is supported for the legacy --host/--port interface. 8) If there are spaces in the parameter values after --mysqld_args, then their further transfer does not occur correctly, which causes mariabackup to fail during SST - the space splits the argument in such a way that it breaks the parsing of the following parameters; 9) If most of the parameters that are names or paths to the files or directories contain spaces, then SST scripts fail in an unpredictable way due to incorrect variable substitutions; 10) If the --log-bin option is passed among the arguments of myqlds (--mysqld-args) without a parameter, and the --binlog option is not specified, then the script cannot substitute the default name for binlog and cannot construct binlog name using the --log-basename argument (which is against server specifications); 11) Tail slashes are not removed from the directory names, which, upon further substitution, leads to the appearance of a double slash in the file paths; 12) The explicit --binlog parameter (which is now always transmitted from the server side) and the "hidden" --log-bin parameter in the list of arguments after --mysqld-args are perceived as two different parameters in different parts of the scripts, and if they are do not match for some reason, this will lead to failures during SST; Also, all new changes from the 10.6 branch have been migrated here, including the latest pull requests for authentication (only the part that concerns SST scripts). It also fixes dozens of other bugs in all SST scripts.

MDEV-23580: WSREP_SST: [ERROR] rsync daemon port has been taken This commit contains a large set of further bug fixes and improvements to SST scripts for Galera, continuing the work that was started in MDEV-24962 to make SST scripts work smoothly in different network configurations (especially using ipv6) and with different environment settings: 1) The ipv6 addresses were incorrectly handled in the SST script for rsync (incorrect address substitution for establishing a connection, incorrect address substitution for bind, and so on); 2) Checking the locality of the ip-address in SST scripts did not support ipv6 addresses (such as "[::1]"), which were falsely identified as non-local ip, which further did not allow running two SSTs on different local addresses on the same machine. On the other hand, this bug masked some other errors (related to handling ipv6 addresses); 3) The code for checking the locality of the ip address was different in the SST scripts for rsync and for mysqldump, with individual flaws. This code is now made common and moved to wsrep_sst_common; 4) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) in the wait_for_listen() and check_pid_and_port() functions did not process ipv6 addresses correctly in all cases (not for all branches); 5) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) in the wait_for_listen() and check_pid_and_port() functions for some code branches could give a false positive result due to the textual match of prefixes in the port number and/or PID of the process; 6) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) was supported through different utilities in SST scripts for mariabackup and for rsync, and with various minor flaws in the code. Now the code is still different in these scripts, but it supports a common set of utilities (lsof, ss, sockstat) and is synchronized across patterns that used to check the output of these utilities; 7) In SST via mariabackup, the signal about readiness to receive data is sometimes sent too early - immediately after listen(), and not after accept() (which are called by socat or netcat utility). 8) Checking availability of the some options of some utilities was done using the grep pattern, which easily gives false positives; 9) Common name (CN) for local addresses, if not explicitly specified, is now always replaced to "localhost" to avoid the need to generate many separate certificates for local addresses of one machine and not to depend on which the local address is currently used in test (ipv4 or ipv6, etc.); 10) In tests galera_sst_mariabackup_encrypt_with_key_server and galera_sst_rsync_encrypt_with_key_server the correct certificate is selected to avoid commonname (CN) mismatch problems; 11) Further refactoring to protect against spaces in file names. 12) Further general refactoring to eliminate bash-specific constructs or to improve code readability; 13) The code for setting options for the nc (netcat) utility was different in different scripts for SST - now it is made identical. 14) Fixed long-time broken encryption via xbcrypt in combination with mariabackup and added support for key-based encryption via openssl utility, which is now enabled by default for encrypt=1 mode (this default mode can be changed using a new configuration file option "encypt-format=openssl|xbcrypt", which can be placed in the [mysqld], [sst] or in the [xtrabackup] section) - this change will allow us to use and to test the encypt=1 encryption without installing non-standard third-party utilities.

MDEV-25818: RSYNC SST failed due to busy port This commit reduces the likelihood of getting a busy port on quick restarts with rsync SST (problem MDEV-25818) and fixes a number of other flaws in SST scripts, adds new functionality, and also synchronizes the xtrabackup-v2 script with the mariabackup script (the latter applies only to the 10.2 branch): 1) SST via rsync: rsync and stunnel does not always get the right time to complete by correctly handling SIGTERM. These utilities are now given more time to complete normally (via normal SIGTERM processing) before we move on to using "kill -9"; 2) SST via rsync: attempts to terminate an rsync or stunnel process (via "kill" utility) are only made if it did not terminated on its own; 3) SST via rsync: if a combination of stunnel and rsync is used, then we need to wait for both utilities to finish or stop, not just one of them; 4) The config file and pid file for stunnel are now deleted after successful completion of SST on the donor node; 5) The configs and pid files from rsync and stunnel should not be deleted unless these utilities succeed (or are sucessfully terminated) on the joiner node; 6) The configs and pid files now excluded from transfer via rsync; 7) Spaces in paths are now valid for config files as well (when used with SST via rsync or mariabackup / xtrabackup[-v2]); 8) SST via mariabackup: added preliminary verification of keys and certificates that are used when establishing a connection using SSL (to avoid long timeouts and improve diagnostics) - by analogy with how it is done for the xtrabackup-v2 (plus check for CA file), while that check is skipped if the user does not have openssl installed (or does not have diff utility); 9) Added backup-threads=<n> configuration option which adds "--parallel=<n>" for mariabackup / xtrabackup at backup and move-back stages; 10) Added encrypt-threads and encrypt-chunk-size configuration options for xbcrypt management (when xbcrypt is used); 11) Small optimization: checking the socat version and adding a file with parameters for 2048-bit Diffie-Hellman (if necessary) is done only if the user has not specified "dhparam=" in the "sockopt" option value; 12) SST via rsync now supports "backup-threads" configuration option (in server-related sections or in the "[sst]"); 13) Determining the number of available processors is now supported for FreeBSD + mariabackup/xtrabackup: before that we might have problems with "--compact" (rebuild indexes) or qpress on FreeBSD; 14) The check_pid() function should not raise an error state in the rare cases when the pid file was created, but it is empty, or if it is deleted right during the check, or when zero is read from the pid file; 15) Iproved templates that are used to check if a requested socket is "listening" when using the ss utility; 16) Shortened some other templates for socket state utilities; 17) Temporary files created by mariabackup / xtrabackup are moved to a separate subdirectory inside tmpdir (so they don't get mixed with other temporary files, which can make debugging more difficult); 18) 10.2 only: the script for SST via xtrabackup-v2 has been brought in full compliance with all the bugfixes made for mariabackup (as it previously contained many flaws compared to the updated script for mariabackup).

These utilities are now given more time to complete normally (via normal SIGTERM processing) before we move on to using "kill -9"; 2) SST via rsync: attempts to terminate an rsync or stunnel process (via "kill" utility) are only made if it did not terminated on its own; 3) SST via rsync: if a combination of stunnel and rsync is used, then we need to wait for both utilities to finish or stop, not just one of them; 4) The config file and pid file for stunnel are now deleted after successful completion of SST on the donor node; 5) The configs and pid files from rsync and stunnel should not be deleted unless these utilities succeed (or are sucessfully terminated) on the joiner node; 6) The configs and pid files now excluded from transfer via rsync; 7) Spaces in paths are now valid for config files as well (when used with SST via rsync or mariabackup / xtrabackup[-v2]); 8) SST via mariabackup: added preliminary verification of keys and certificates that are used when establishing a connection using SSL (to avoid long timeouts and improve diagnostics) - by analogy with how it is done for the xtrabackup-v2 (plus check for CA file), while that check is skipped if the user does not have openssl installed (or does not have diff utility); 9) Added backup-threads=<n> configuration option which adds "--parallel=<n>" for mariabackup / xtrabackup at backup and move-back stages; 10) Added encrypt-threads and encrypt-chunk-size configuration options for xbcrypt management (when xbcrypt is used); 11) Small optimization: checking the socat version and adding a file with parameters for 2048-bit Diffie-Hellman (if necessary) is done only if the user has not specified "dhparam=" in the "sockopt" option value; 12) SST via rsync now supports "backup-threads" configuration option (in server-related sections or in the "[sst]"); 13) Determining the number of available processors is now supported for FreeBSD + mariabackup/xtrabackup: before that we might have problems with "--compact" (rebuild indexes) or qpress on FreeBSD; 14) The check_pid() function should not raise an error state in the rare cases when the pid file was created, but it is empty, or if it is deleted right during the check, or when zero is read from the pid file; 15) Iproved templates that are used to check if a requested socket is "listening" when using the ss utility; 16) Shortened some other templates for socket state utilities; 17) Temporary files created by mariabackup / xtrabackup are moved to a separate subdirectory inside tmpdir (so they don't get mixed with other temporary files, which can make debugging more difficult); 18) 10.2 only: the script for SST via xtrabackup-v2 has been brought in full compliance with all the bugfixes made for mariabackup (as it previously contained many flaws compared to the updated script for mariabackup).

MDEV-24962: Galera SST innobackupex-move ignores Environment settings After switching to the new mariabackup interface (instead of the outdated innobackupex interface, which is supported for compatibility), we need to explicitly pass a path to the datadir directory as a parameter, since in the new interface the value of this option is not automatically set in such a way that it always matches the SST/IST logic. This commit adds passing this option as an explicit parameter to mariabackup. This commit also removed unnecessary options that are not used and not supported by mariabackup. Also, numerous flaws in the common wsrep_sst_common script have been fixed: 1) There are many bash-specific constructs in the script that may not be supported by other interpreters, which can lead to the most unexpected errors during SST, because failures in the interpretation of bash-specific constructs lead to incorrect parsing of arguments; 2) There is parse_cnf() function which is often called by other scripts for the "mysqld" or "--mysqld" group, but it does not take into account the default group suffix, which leads to reading values only from the default group, which then leads to errors due to reading the default values instead of the values for a specific group; 3) Some options such as --user, --innodb-data-home-dir or --datadir are not removed from the --mysqld-args list, although they are processed inside scripts (and passing of these options funther may cause problems for mariabackup); 4) If an argument that the script understands is present in the --mysqld-args list twice, then this causes SST to fail, instead of reading the most recent value; 5) The "--host" parameter is technically still supported among the arguments of the SST scripts, but in reality scripts do not work with it as expected, especially if it has an IPv6 address; 6) If the port number is absent in the --address parameter value, but the port number is explicitly passed through the --port argument, then the scripts for mariabackup and xtrabackup-v2 fail; 7) If a new address interface is used (with the --address parameter), then automatic default port substitution is not performed, although it is supported for the legacy --host/--port interface. 8) If there are spaces in the parameter values after --mysqld_args, then their further transfer does not occur correctly, which causes mariabackup to fail during SST - the space splits the argument in such a way that it breaks the parsing of the following parameters; 9) If most of the parameters that are names or paths to the files or directories contain spaces, then SST scripts fail in an unpredictable way due to incorrect variable substitutions; 10) If the --log-bin option is passed among the arguments of myqlds (--mysqld-args) without a parameter, and the --binlog option is not specified, then the script cannot substitute the default name for binlog and cannot construct binlog name using the --log-basename argument (which is against server specifications); 11) Tail slashes are not removed from the directory names, which, upon further substitution, leads to the appearance of a double slash in the file paths; 12) The explicit --binlog parameter (which is now always transmitted from the server side) and the "hidden" --log-bin parameter in the list of arguments after --mysqld-args are perceived as two different parameters in different parts of the scripts, and if they are do not match for some reason, this will lead to failures during SST; Also, all new changes from the 10.6 branch have been migrated here, including the latest pull requests for authentication (only the part that concerns SST scripts). It also fixes dozens of other bugs in all SST scripts.

MDEV-27524: Incorrect binlogs after Galera SST using rsync and mariabackup This commit adds correct handling of binlogs for SST using rsync or mariabackup. Before this fix, binlogs were handled incorrectly - - only one (last) binary log file was transferred during SST, which then led to various failures (for example, when trying to list all events from the binary log). These bugs were long masked by flaws in the primitive binlogs handling code in the SST scripts, which causing binary logs files to be erased after transfer or not added to the binlog index on the joiner node. Now the correct transfer of all binary logs (not just the last of the binary log files) has been implemented both for the rsync (at the script level) and for the mariabackup (at the level of the main utility code). This commit also adds a new sst_max_binlogs=<n> parameter, which can be located in the [sst] section or in the [xtrabackup] section (historically, supported for mariabackup only, not for rsync), or in one of the server sections. This parameter specifies the number of binary log files to be sent to the joiner node during SST. This option is added for compatibility with old SST scripting behavior, which can be emulated by setting the sst_max_binlogs=1 (although in general this can cause problems for the reasons described above). In addition, setting the sst_max_binlogs=0 can be used to suppress the transmission of binary logs to the joiner nodes during SST (although sometimes a single file with the current binary log can still be transmitted to the joiner, even with sst_max_binlogs=0, because this sometimes necessary in modes that involve the use of GTIDs with Galera). Also, this commit ensures correct handling of paths to various innodb files and directories in the SST scripts, and fixes some problems with this that existed in mariabackup utility (which were associated with incorrect handling of the innodb_data_dir parameter in some scenarios). In addition, this commit contains the following enhancements: 1) Added tests for mtr, which check the correct work with binlogs after SST (using rsync and mariabackup); 2) Added correct handling of slashes at the end of all paths that the SST script receives as parameters; 3) Improved parsing code for --mysqld-args parameters. Now it correctly processes the sequence "--" after the name of the one-letter option; 4) Checking the secret signature during joiner authentication is made independent of presence of bash (as a unix shell) in the system and diff utility no longer needed to check certificates compliance; 5) All directories that are necessary for the correct placement of various logs are automatically created by SST scripts in advance (before running mariabackup on the joiner node); 6) Removal of old binary logs on joiner is done using the binlog index (if it exists) (not only by fixed pattern that based on the current binlog name, as before); 7) Paths for placing binary logs are correctly processed if they are set as relative paths (to the datadir); 8) SST scripts are made even more resistant to spaces in filenames (now for binlogs); 9) In case of failure, SST scripts now always end with an exit code other than zero; 10) SST script for rsync now correctly create a tar file with the binlogs, even if the paths to them (in the binlog index file) are specified as a mix of absolute and relative paths, and even if they do not match with the datadir path specified in the current configuration settings.

MDEV-24097: galera[_3nodes] suite tests in MTR sporadically fails This is the first part of the fixes for MDEV-24097. This commit contains the fixes for instability when testing Galera and when restarting nodes quickly: 1) Protection against a "stuck" old SST process during the execution of the new SST (after restarting the node) is now implemented for mariabackup / xtrabackup, which should help to avoid almost all conflicts due to the use of the same ports - both during testing with mtr, so and when restarting nodes quickly in a production environment. 2) Added more protection to scripts against unexpected return of the rc != 0 (in the commands for deleting temporary files, etc). 3) Added protection against unexpected crashes during binlog transfer (in SST scripts for rsync). 4) Spaces and some special characters in binlog filenames shouldn't be a problem now (at the script level). 5) Daemon process termination tracking has been made more robust against crashes due to unexpected termination of the previous SST process while new scripts are running. 6) Reading ssl encryption parameters has been moved from specific SST scripts to a common wsrep_sst_common.sh script, which allows unified error handling, unified diagnostics and simplifies script revisions in the future. 7) Improved diagnostics of errors related to the use of openssl. 8) Corrections have been made for xtrabackup-v2 (both in tests and in the script code) that restore the work of xtrabackup with updated versions of innodb. 9) Fixed some tests for galera_3nodes, although the complete solution for the problem of starting three nodes at the same time on fast machines will be done in a separate commit. No additional tests are required as this commit fixes problems with existing tests.

These utilities are now given more time to complete normally (via normal SIGTERM processing) before we move on to using "kill -9"; 2) SST via rsync: attempts to terminate an rsync or stunnel process (via "kill" utility) are only made if it did not terminated on its own; 3) SST via rsync: if a combination of stunnel and rsync is used, then we need to wait for both utilities to finish or stop, not just one of them; 4) The config file and pid file for stunnel are now deleted after successful completion of SST on the donor node; 5) The configs and pid files from rsync and stunnel should not be deleted unless these utilities succeed (or are sucessfully terminated) on the joiner node; 6) The configs and pid files now excluded from transfer via rsync; 7) Spaces in paths are now valid for config files as well (when used with SST via rsync or mariabackup / xtrabackup[-v2]); 8) SST via mariabackup: added preliminary verification of keys and certificates that are used when establishing a connection using SSL (to avoid long timeouts and improve diagnostics) - by analogy with how it is done for the xtrabackup-v2 (plus check for CA file), while that check is skipped if the user does not have openssl installed (or does not have diff utility); 9) Added backup-threads=<n> configuration option which adds "--parallel=<n>" for mariabackup / xtrabackup at backup and move-back stages; 10) Added encrypt-threads and encrypt-chunk-size configuration options for xbcrypt management (when xbcrypt is used); 11) Small optimization: checking the socat version and adding a file with parameters for 2048-bit Diffie-Hellman (if necessary) is done only if the user has not specified "dhparam=" in the "sockopt" option value; 12) SST via rsync now supports "backup-threads" configuration option (in server-related sections or in the "[sst]"); 13) Determining the number of available processors is now supported for FreeBSD + mariabackup/xtrabackup: before that we might have problems with "--compact" (rebuild indexes) or qpress on FreeBSD; 14) The check_pid() function should not raise an error state in the rare cases when the pid file was created, but it is empty, or if it is deleted right during the check, or when zero is read from the pid file; 15) Iproved templates that are used to check if a requested socket is "listening" when using the ss utility; 16) Shortened some other templates for socket state utilities; 17) Temporary files created by mariabackup / xtrabackup are moved to a separate subdirectory inside tmpdir (so they don't get mixed with other temporary files, which can make debugging more difficult); 18) 10.2 only: the script for SST via xtrabackup-v2 has been brought in full compliance with all the bugfixes made for mariabackup (as it previously contained many flaws compared to the updated script for mariabackup).

MDEV-24097: galera[_3nodes] suite tests in MTR sporadically fails This is the first part of the fixes for MDEV-24097. This commit contains the fixes for instability when testing Galera and when restarting nodes quickly: 1) Protection against a "stuck" old SST process during the execution of the new SST (after restarting the node) is now implemented for mariabackup / xtrabackup, which should help to avoid almost all conflicts due to the use of the same ports - both during testing with mtr, so and when restarting nodes quickly in a production environment. 2) Added more protection to scripts against unexpected return of the rc != 0 (in the commands for deleting temporary files, etc). 3) Added protection against unexpected crashes during binlog transfer (in SST scripts for rsync). 4) Spaces and some special characters in binlog filenames shouldn't be a problem now (at the script level). 5) Daemon process termination tracking has been made more robust against crashes due to unexpected termination of the previous SST process while new scripts are running. 6) Reading ssl encryption parameters has been moved from specific SST scripts to a common wsrep_sst_common.sh script, which allows unified error handling, unified diagnostics and simplifies script revisions in the future. 7) Improved diagnostics of errors related to the use of openssl. 8) Corrections have been made for xtrabackup-v2 (both in tests and in the script code) that restore the work of xtrabackup with updated versions of innodb. 9) Fixed some tests for galera_3nodes, although the complete solution for the problem of starting three nodes at the same time on fast machines will be done in a separate commit. No additional tests are required as this commit fixes problems with existing tests.

MDEV-24962: Galera SST innobackupex-move ignores Environment settings After switching to the new mariabackup interface (instead of the outdated innobackupex interface, which is supported for compatibility), we need to explicitly pass a path to the datadir directory as a parameter, since in the new interface the value of this option is not automatically set in such a way that it always matches the SST/IST logic. This commit adds passing this option as an explicit parameter to mariabackup. This commit also removed unnecessary options that are not used and not supported by mariabackup. Also, numerous flaws in the common wsrep_sst_common script have been fixed: 1) There are many bash-specific constructs in the script that may not be supported by other interpreters, which can lead to the most unexpected errors during SST, because failures in the interpretation of bash-specific constructs lead to incorrect parsing of arguments; 2) There is parse_cnf() function which is often called by other scripts for the "mysqld" or "--mysqld" group, but it does not take into account the default group suffix, which leads to reading values only from the default group, which then leads to errors due to reading the default values instead of the values for a specific group; 3) Some options such as --user, --innodb-data-home-dir or --datadir are not removed from the --mysqld-args list, although they are processed inside scripts (and passing of these options funther may cause problems for mariabackup); 4) If an argument that the script understands is present in the --mysqld-args list twice, then this causes SST to fail, instead of reading the most recent value; 5) The "--host" parameter is technically still supported among the arguments of the SST scripts, but in reality scripts do not work with it as expected, especially if it has an IPv6 address; 6) If the port number is absent in the --address parameter value, but the port number is explicitly passed through the --port argument, then the scripts for mariabackup and xtrabackup-v2 fail; 7) If a new address interface is used (with the --address parameter), then automatic default port substitution is not performed, although it is supported for the legacy --host/--port interface. 8) If there are spaces in the parameter values after --mysqld_args, then their further transfer does not occur correctly, which causes mariabackup to fail during SST - the space splits the argument in such a way that it breaks the parsing of the following parameters; 9) If most of the parameters that are names or paths to the files or directories contain spaces, then SST scripts fail in an unpredictable way due to incorrect variable substitutions; 10) If the --log-bin option is passed among the arguments of myqlds (--mysqld-args) without a parameter, and the --binlog option is not specified, then the script cannot substitute the default name for binlog and cannot construct binlog name using the --log-basename argument (which is against server specifications); 11) Tail slashes are not removed from the directory names, which, upon further substitution, leads to the appearance of a double slash in the file paths; 12) The explicit --binlog parameter (which is now always transmitted from the server side) and the "hidden" --log-bin parameter in the list of arguments after --mysqld-args are perceived as two different parameters in different parts of the scripts, and if they are do not match for some reason, this will lead to failures during SST; Also, all new changes from the 10.6 branch have been migrated here, including the latest pull requests for authentication (only the part that concerns SST scripts). It also fixes dozens of other bugs in all SST scripts.

MDEV-23580: WSREP_SST: [ERROR] rsync daemon port has been taken This commit contains a large set of further bug fixes and improvements to SST scripts for Galera, continuing the work that was started in MDEV-24962 to make SST scripts work smoothly in different network configurations (especially using ipv6) and with different environment settings: 1) The ipv6 addresses were incorrectly handled in the SST script for rsync (incorrect address substitution for establishing a connection, incorrect address substitution for bind, and so on); 2) Checking the locality of the ip-address in SST scripts did not support ipv6 addresses (such as "[::1]"), which were falsely identified as non-local ip, which further did not allow running two SSTs on different local addresses on the same machine. On the other hand, this bug masked some other errors (related to handling ipv6 addresses); 3) The code for checking the locality of the ip address was different in the SST scripts for rsync and for mysqldump, with individual flaws. This code is now made common and moved to wsrep_sst_common; 4) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) in the wait_for_listen() and check_pid_and_port() functions did not process ipv6 addresses correctly in all cases (not for all branches); 5) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) in the wait_for_listen() and check_pid_and_port() functions for some code branches could give a false positive result due to the textual match of prefixes in the port number and/or PID of the process; 6) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) was supported through different utilities in SST scripts for mariabackup and for rsync, and with various minor flaws in the code. Now the code is still different in these scripts, but it supports a common set of utilities (lsof, ss, sockstat) and is synchronized across patterns that used to check the output of these utilities; 7) In SST via mariabackup, the signal about readiness to receive data is sometimes sent too early - immediately after listen(), and not after accept() (which are called by socat or netcat utility). 8) Checking availability of the some options of some utilities was done using the grep pattern, which easily gives false positives; 9) Common name (CN) for local addresses, if not explicitly specified, is now always replaced to "localhost" to avoid the need to generate many separate certificates for local addresses of one machine and not to depend on which the local address is currently used in test (ipv4 or ipv6, etc.); 10) In tests galera_sst_mariabackup_encrypt_with_key_server and galera_sst_rsync_encrypt_with_key_server the correct certificate is selected to avoid commonname (CN) mismatch problems; 11) Further refactoring to protect against spaces in file names. 12) Further general refactoring to eliminate bash-specific constructs or to improve code readability; 13) The code for setting options for the nc (netcat) utility was different in different scripts for SST - now it is made identical. 14) Fixed long-time broken encryption via xbcrypt in combination with mariabackup and added support for key-based encryption via openssl utility, which is now enabled by default for encrypt=1 mode (this default mode can be changed using a new configuration file option "encypt-format=openssl|xbcrypt", which can be placed in the [mysqld], [sst] or in the [xtrabackup] section) - this change will allow us to use and to test the encypt=1 encryption without installing non-standard third-party utilities.

MDEV-25818: RSYNC SST failed due to busy port This commit reduces the likelihood of getting a busy port on quick restarts with rsync SST (problem MDEV-25818) and fixes a number of other flaws in SST scripts, adds new functionality, and also synchronizes the xtrabackup-v2 script with the mariabackup script (the latter applies only to the 10.2 branch): 1) SST via rsync: rsync and stunnel does not always get the right time to complete by correctly handling SIGTERM. These utilities are now given more time to complete normally (via normal SIGTERM processing) before we move on to using "kill -9"; 2) SST via rsync: attempts to terminate an rsync or stunnel process (via "kill" utility) are only made if it did not terminated on its own; 3) SST via rsync: if a combination of stunnel and rsync is used, then we need to wait for both utilities to finish or stop, not just one of them; 4) The config file and pid file for stunnel are now deleted after successful completion of SST on the donor node; 5) The configs and pid files from rsync and stunnel should not be deleted unless these utilities succeed (or are sucessfully terminated) on the joiner node; 6) The configs and pid files now excluded from transfer via rsync; 7) Spaces in paths are now valid for config files as well (when used with SST via rsync or mariabackup / xtrabackup[-v2]); 8) SST via mariabackup: added preliminary verification of keys and certificates that are used when establishing a connection using SSL (to avoid long timeouts and improve diagnostics) - by analogy with how it is done for the xtrabackup-v2 (plus check for CA file), while that check is skipped if the user does not have openssl installed (or does not have diff utility); 9) Added backup-threads=<n> configuration option which adds "--parallel=<n>" for mariabackup / xtrabackup at backup and move-back stages; 10) Added encrypt-threads and encrypt-chunk-size configuration options for xbcrypt management (when xbcrypt is used); 11) Small optimization: checking the socat version and adding a file with parameters for 2048-bit Diffie-Hellman (if necessary) is done only if the user has not specified "dhparam=" in the "sockopt" option value; 12) SST via rsync now supports "backup-threads" configuration option (in server-related sections or in the "[sst]"); 13) Determining the number of available processors is now supported for FreeBSD + mariabackup/xtrabackup: before that we might have problems with "--compact" (rebuild indexes) or qpress on FreeBSD; 14) The check_pid() function should not raise an error state in the rare cases when the pid file was created, but it is empty, or if it is deleted right during the check, or when zero is read from the pid file; 15) Iproved templates that are used to check if a requested socket is "listening" when using the ss utility; 16) Shortened some other templates for socket state utilities; 17) Temporary files created by mariabackup / xtrabackup are moved to a separate subdirectory inside tmpdir (so they don't get mixed with other temporary files, which can make debugging more difficult); 18) 10.2 only: the script for SST via xtrabackup-v2 has been brought in full compliance with all the bugfixes made for mariabackup (as it previously contained many flaws compared to the updated script for mariabackup).

MDEV-23580: WSREP_SST: [ERROR] rsync daemon port has been taken This commit contains a large set of further bug fixes and improvements to SST scripts for Galera, continuing the work that was started in MDEV-24962 to make SST scripts work smoothly in different network configurations (especially using ipv6) and with different environment settings: 1) The ipv6 addresses were incorrectly handled in the SST script for rsync (incorrect address substitution for establishing a connection, incorrect address substitution for bind, and so on); 2) Checking the locality of the ip-address in SST scripts did not support ipv6 addresses (such as "[::1]"), which were falsely identified as non-local ip, which further did not allow running two SSTs on different local addresses on the same machine. On the other hand, this bug masked some other errors (related to handling ipv6 addresses); 3) The code for checking the locality of the ip address was different in the SST scripts for rsync and for mysqldump, with individual flaws. This code is now made common and moved to wsrep_sst_common; 4) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) in the wait_for_listen() and check_pid_and_port() functions did not process ipv6 addresses correctly in all cases (not for all branches); 5) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) in the wait_for_listen() and check_pid_and_port() functions for some code branches could give a false positive result due to the textual match of prefixes in the port number and/or PID of the process; 6) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) was supported through different utilities in SST scripts for mariabackup and for rsync, and with various minor flaws in the code. Now the code is still different in these scripts, but it supports a common set of utilities (lsof, ss, sockstat) and is synchronized across patterns that used to check the output of these utilities; 7) In SST via mariabackup, the signal about readiness to receive data is sometimes sent too early - immediately after listen(), and not after accept() (which are called by socat or netcat utility). 8) Checking availability of the some options of some utilities was done using the grep pattern, which easily gives false positives; 9) Common name (CN) for local addresses, if not explicitly specified, is now always replaced to "localhost" to avoid the need to generate many separate certificates for local addresses of one machine and not to depend on which the local address is currently used in test (ipv4 or ipv6, etc.); 10) In tests galera_sst_mariabackup_encrypt_with_key_server and galera_sst_rsync_encrypt_with_key_server the correct certificate is selected to avoid commonname (CN) mismatch problems; 11) Further refactoring to protect against spaces in file names. 12) Further general refactoring to eliminate bash-specific constructs or to improve code readability; 13) The code for setting options for the nc (netcat) utility was different in different scripts for SST - now it is made identical. 14) Fixed long-time broken encryption via xbcrypt in combination with mariabackup and added support for key-based encryption via openssl utility, which is now enabled by default for encrypt=1 mode (this default mode can be changed using a new configuration file option "encypt-format=openssl|xbcrypt", which can be placed in the [mysqld], [sst] or in the [xtrabackup] section) - this change will allow us to use and to test the encypt=1 encryption without installing non-standard third-party utilities.

MDEV-24962: Galera SST innobackupex-move ignores Environment settings After switching to the new mariabackup interface (instead of the outdated innobackupex interface, which is supported for compatibility), we need to explicitly pass a path to the datadir directory as a parameter, since in the new interface the value of this option is not automatically set in such a way that it always matches the SST/IST logic. This commit adds passing this option as an explicit parameter to mariabackup. This commit also removed unnecessary options that are not used and not supported by mariabackup. Also, numerous flaws in the common wsrep_sst_common script have been fixed: 1) There are many bash-specific constructs in the script that may not be supported by other interpreters, which can lead to the most unexpected errors during SST, because failures in the interpretation of bash-specific constructs lead to incorrect parsing of arguments; 2) There is parse_cnf() function which is often called by other scripts for the "mysqld" or "--mysqld" group, but it does not take into account the default group suffix, which leads to reading values only from the default group, which then leads to errors due to reading the default values instead of the values for a specific group; 3) Some options such as --user, --innodb-data-home-dir or --datadir are not removed from the --mysqld-args list, although they are processed inside scripts (and passing of these options funther may cause problems for mariabackup); 4) If an argument that the script understands is present in the --mysqld-args list twice, then this causes SST to fail, instead of reading the most recent value; 5) The "--host" parameter is technically still supported among the arguments of the SST scripts, but in reality scripts do not work with it as expected, especially if it has an IPv6 address; 6) If the port number is absent in the --address parameter value, but the port number is explicitly passed through the --port argument, then the scripts for mariabackup and xtrabackup-v2 fail; 7) If a new address interface is used (with the --address parameter), then automatic default port substitution is not performed, although it is supported for the legacy --host/--port interface. 8) If there are spaces in the parameter values after --mysqld_args, then their further transfer does not occur correctly, which causes mariabackup to fail during SST - the space splits the argument in such a way that it breaks the parsing of the following parameters; 9) If most of the parameters that are names or paths to the files or directories contain spaces, then SST scripts fail in an unpredictable way due to incorrect variable substitutions; 10) If the --log-bin option is passed among the arguments of myqlds (--mysqld-args) without a parameter, and the --binlog option is not specified, then the script cannot substitute the default name for binlog and cannot construct binlog name using the --log-basename argument (which is against server specifications); 11) Tail slashes are not removed from the directory names, which, upon further substitution, leads to the appearance of a double slash in the file paths; 12) The explicit --binlog parameter (which is now always transmitted from the server side) and the "hidden" --log-bin parameter in the list of arguments after --mysqld-args are perceived as two different parameters in different parts of the scripts, and if they are do not match for some reason, this will lead to failures during SST; Also, all new changes from the 10.6 branch have been migrated here, including the latest pull requests for authentication (only the part that concerns SST scripts). It also fixes dozens of other bugs in all SST scripts.

MDEV-23580: WSREP_SST: [ERROR] rsync daemon port has been taken This commit contains a large set of further bug fixes and improvements to SST scripts for Galera, continuing the work that was started in MDEV-24962 to make SST scripts work smoothly in different network configurations (especially using ipv6) and with different environment settings: 1) The ipv6 addresses were incorrectly handled in the SST script for rsync (incorrect address substitution for establishing a connection, incorrect address substitution for bind, and so on); 2) Checking the locality of the ip-address in SST scripts did not support ipv6 addresses (such as "[::1]"), which were falsely identified as non-local ip, which further did not allow running two SSTs on different local addresses on the same machine. On the other hand, this bug masked some other errors (related to handling ipv6 addresses); 3) The code for checking the locality of the ip address was different in the SST scripts for rsync and for mysqldump, with individual flaws. This code is now made common and moved to wsrep_sst_common; 4) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) in the wait_for_listen() and check_pid_and_port() functions did not process ipv6 addresses correctly in all cases (not for all branches); 5) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) in the wait_for_listen() and check_pid_and_port() functions for some code branches could give a false positive result due to the textual match of prefixes in the port number and/or PID of the process; 6) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) was supported through different utilities in SST scripts for mariabackup and for rsync, and with various minor flaws in the code.

MDEV-24962: Galera SST innobackupex-move ignores Environment settings After switching to the new mariabackup interface (instead of the outdated innobackupex interface, which is supported for compatibility), we need to explicitly pass a path to the datadir directory as a parameter, since in the new interface the value of this option is not automatically set in such a way that it always matches the SST/IST logic. This commit adds passing this option as an explicit parameter to mariabackup. This commit also removed unnecessary options that are not used and not supported by mariabackup. Also, numerous flaws in the common wsrep_sst_common script have been fixed: 1) There are many bash-specific constructs in the script that may not be supported by other interpreters, which can lead to the most unexpected errors during SST, because failures in the interpretation of bash-specific constructs lead to incorrect parsing of arguments; 2) There is parse_cnf() function which is often called by other scripts for the "mysqld" or "--mysqld" group, but it does not take into account the default group suffix, which leads to reading values only from the default group, which then leads to errors due to reading the default values instead of the values for a specific group; 3) Some options such as --user, --innodb-data-home-dir or --datadir are not removed from the --mysqld-args list, although they are processed inside scripts (and passing of these options funther may cause problems for mariabackup); 4) If an argument that the script understands is present in the --mysqld-args list twice, then this causes SST to fail, instead of reading the most recent value; 5) The "--host" parameter is technically still supported among the arguments of the SST scripts, but in reality scripts do not work with it as expected, especially if it has an IPv6 address; 6) If the port number is absent in the --address parameter value, but the port number is explicitly passed through the --port argument, then the scripts for mariabackup and xtrabackup-v2 fail; 7) If a new address interface is used (with the --address parameter), then automatic default port substitution is not performed, although it is supported for the legacy --host/--port interface. 8) If there are spaces in the parameter values after --mysqld_args, then their further transfer does not occur correctly, which causes mariabackup to fail during SST - the space splits the argument in such a way that it breaks the parsing of the following parameters; 9) If most of the parameters that are names or paths to the files or directories contain spaces, then SST scripts fail in an unpredictable way due to incorrect variable substitutions; 10) If the --log-bin option is passed among the arguments of myqlds (--mysqld-args) without a parameter, and the --binlog option is not specified, then the script cannot substitute the default name for binlog and cannot construct binlog name using the --log-basename argument (which is against server specifications); 11) Tail slashes are not removed from the directory names, which, upon further substitution, leads to the appearance of a double slash in the file paths; 12) The explicit --binlog parameter (which is now always transmitted from the server side) and the "hidden" --log-bin parameter in the list of arguments after --mysqld-args are perceived as two different parameters in different parts of the scripts, and if they are do not match for some reason, this will lead to failures during SST; Also, all new changes from the 10.6 branch have been migrated here, including the latest pull requests for authentication (only the part that concerns SST scripts). It also fixes dozens of other bugs in all SST scripts.

Also, numerous flaws in the common wsrep_sst_common script have been fixed: 1) There are many bash-specific constructs in the script that may not be supported by other interpreters, which can lead to the most unexpected errors during SST, because failures in the interpretation of bash-specific constructs lead to incorrect parsing of arguments; 2) There is parse_cnf() function which is often called by other scripts for the "mysqld" or "--mysqld" group, but it does not take into account the default group suffix, which leads to reading values only from the default group, which then leads to errors due to reading the default values instead of the values for a specific group; 3) Some options such as --user, --innodb-data-home-dir or --datadir are not removed from the --mysqld-args list, although they are processed inside scripts (and passing of these options funther may cause problems for mariabackup); 4) If an argument that the script understands is present in the --mysqld-args list twice, then this causes SST to fail, instead of reading the most recent value; 5) The "--host" parameter is technically still supported among the arguments of the SST scripts, but in reality scripts do not work with it as expected, especially if it has an IPv6 address; 6) If the port number is absent in the --address parameter value, but the port number is explicitly passed through the --port argument, then the scripts for mariabackup and xtrabackup-v2 fail; 7) If a new address interface is used (with the --address parameter), then automatic default port substitution is not performed, although it is supported for the legacy --host/--port interface. 8) If there are spaces in the parameter values after --mysqld_args, then their further transfer does not occur correctly, which causes mariabackup to fail during SST - the space splits the argument in such a way that it breaks the parsing of the following parameters; 9) If most of the parameters that are names or paths to the files or directories contain spaces, then SST scripts fail in an unpredictable way due to incorrect variable substitutions; 10) If the --log-bin option is passed among the arguments of myqlds (--mysqld-args) without a parameter, and the --binlog option is not specified, then the script cannot substitute the default name for binlog and cannot construct binlog name using the --log-basename argument (which is against server specifications); 11) Tail slashes are not removed from the directory names, which, upon further substitution, leads to the appearance of a double slash in the file paths; 12) The explicit --binlog parameter (which is now always transmitted from the server side) and the "hidden" --log-bin parameter in the list of arguments after --mysqld-args are perceived as two different parameters in different parts of the scripts, and if they are do not match for some reason, this will lead to failures during SST; Also, all new changes from the 10.6 branch have been migrated here, including the latest pull requests for authentication (only the part that concerns SST scripts). It also fixes dozens of other bugs in all SST scripts.

MDEV-23580: WSREP_SST: [ERROR] rsync daemon port has been taken This commit contains a large set of further bug fixes and improvements to SST scripts for Galera, continuing the work that was started in MDEV-24962 to make SST scripts work smoothly in different network configurations (especially using ipv6) and with different environment settings: 1) The ipv6 addresses were incorrectly handled in the SST script for rsync (incorrect address substitution for establishing a connection, incorrect address substitution for bind, and so on); 2) Checking the locality of the ip-address in SST scripts did not support ipv6 addresses (such as "[::1]"), which were falsely identified as non-local ip, which further did not allow running two SSTs on different local addresses on the same machine. On the other hand, this bug masked some other errors (related to handling ipv6 addresses); 3) The code for checking the locality of the ip address was different in the SST scripts for rsync and for mysqldump, with individual flaws. This code is now made common and moved to wsrep_sst_common; 4) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) in the wait_for_listen() and check_pid_and_port() functions did not process ipv6 addresses correctly in all cases (not for all branches); 5) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) in the wait_for_listen() and check_pid_and_port() functions for some code branches could give a false positive result due to the textual match of prefixes in the port number and/or PID of the process; 6) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) was supported through different utilities in SST scripts for mariabackup and for rsync, and with various minor flaws in the code. Now the code is still different in these scripts, but it supports a common set of utilities (lsof, ss, sockstat) and is synchronized across patterns that used to check the output of these utilities; 7) In SST via mariabackup, the signal about readiness to receive data is sometimes sent too early - immediately after listen(), and not after accept() (which are called by socat or netcat utility). 8) Checking availability of the some options of some utilities was done using the grep pattern, which easily gives false positives; 9) Common name (CN) for local addresses, if not explicitly specified, is now always replaced to "localhost" to avoid the need to generate many separate certificates for local addresses of one machine and not to depend on which the local address is currently used in test (ipv4 or ipv6, etc.); 10) In tests galera_sst_mariabackup_encrypt_with_key_server and galera_sst_rsync_encrypt_with_key_server the correct certificate is selected to avoid commonname (CN) mismatch problems; 11) Further refactoring to protect against spaces in file names. 12) Further general refactoring to eliminate bash-specific constructs or to improve code readability; 13) The code for setting options for the nc (netcat) utility was different in different scripts for SST - now it is made identical. 14) Fixed long-time broken encryption via xbcrypt in combination with mariabackup and added support for key-based encryption via openssl utility, which is now enabled by default for encrypt=1 mode (this default mode can be changed using a new configuration file option "encypt-format=openssl|xbcrypt", which can be placed in the [mysqld], [sst] or in the [xtrabackup] section) - this change will allow us to use and to test the encypt=1 encryption without installing non-standard third-party utilities.

MDEV-27524: Incorrect binlogs after Galera SST using rsync and mariabackup This commit adds correct handling of binlogs for SST using rsync or mariabackup. Before this fix, binlogs were handled incorrectly - - only one (last) binary log file was transferred during SST, which then led to various failures (for example, when trying to list all events from the binary log). These bugs were long masked by flaws in the primitive binlogs handling code in the SST scripts, which causing binary logs files to be erased after transfer or not added to the binlog index on the joiner node. Now the correct transfer of all binary logs (not just the last of the binary log files) has been implemented both for the rsync (at the script level) and for the mariabackup (at the level of the main utility code). This commit also adds a new sst_max_binlogs=<n> parameter, which can be located in the [sst] section or in the [xtrabackup] section (historically, supported for mariabackup only, not for rsync), or in one of the server sections. This parameter specifies the number of binary log files to be sent to the joiner node during SST. This option is added for compatibility with old SST scripting behavior, which can be emulated by setting the sst_max_binlogs=1 (although in general this can cause problems for the reasons described above). In addition, setting the sst_max_binlogs=0 can be used to suppress the transmission of binary logs to the joiner nodes during SST (although sometimes a single file with the current binary log can still be transmitted to the joiner, even with sst_max_binlogs=0, because this sometimes necessary in modes that involve the use of GTIDs with Galera). Also, this commit ensures correct handling of paths to various innodb files and directories in the SST scripts, and fixes some problems with this that existed in mariabackup utility (which were associated with incorrect handling of the innodb_data_dir parameter in some scenarios). In addition, this commit contains the following enhancements: 1) Added tests for mtr, which check the correct work with binlogs after SST (using rsync and mariabackup); 2) Added correct handling of slashes at the end of all paths that the SST script receives as parameters; 3) Improved parsing code for --mysqld-args parameters. Now it correctly processes the sequence "--" after the name of the one-letter option; 4) Checking the secret signature during joiner authentication is made independent of presence of bash (as a unix shell) in the system and diff utility no longer needed to check certificates compliance; 5) All directories that are necessary for the correct placement of various logs are automatically created by SST scripts in advance (before running mariabackup on the joiner node); 6) Removal of old binary logs on joiner is done using the binlog index (if it exists) (not only by fixed pattern that based on the current binlog name, as before); 7) Paths for placing binary logs are correctly processed if they are set as relative paths (to the datadir); 8) SST scripts are made even more resistant to spaces in filenames (now for binlogs); 9) In case of failure, SST scripts now always end with an exit code other than zero; 10) SST script for rsync now correctly create a tar file with the binlogs, even if the paths to them (in the binlog index file) are specified as a mix of absolute and relative paths, and even if they do not match with the datadir path specified in the current configuration settings.

Before this fix, binlogs were handled incorrectly - - only one (last) binary log file was transferred during SST, which then led to various failures (for example, when trying to list all events from the binary log). These bugs were long masked by flaws in the primitive binlogs handling code in the SST scripts, which causing binary logs files to be erased after transfer or not added to the binlog index on the joiner node. Now the correct transfer of all binary logs (not just the last of the binary log files) has been implemented both for the rsync (at the script level) and for the mariabackup (at the level of the main utility code). This commit also adds a new sst_max_binlogs=<n> parameter, which can be located in the [sst] section or in the [xtrabackup] section (historically, supported for mariabackup only, not for rsync), or in one of the server sections. This parameter specifies the number of binary log files to be sent to the joiner node during SST. This option is added for compatibility with old SST scripting behavior, which can be emulated by setting the sst_max_binlogs=1 (although in general this can cause problems for the reasons described above). In addition, setting the sst_max_binlogs=0 can be used to suppress the transmission of binary logs to the joiner nodes during SST (although sometimes a single file with the current binary log can still be transmitted to the joiner, even with sst_max_binlogs=0, because this sometimes necessary in modes that involve the use of GTIDs with Galera). Also, this commit ensures correct handling of paths to various innodb files and directories in the SST scripts, and fixes some problems with this that existed in mariabackup utility (which were associated with incorrect handling of the innodb_data_dir parameter in some scenarios). In addition, this commit contains the following enhancements: 1) Added tests for mtr, which check the correct work with binlogs after SST (using rsync and mariabackup); 2) Added correct handling of slashes at the end of all paths that the SST script receives as parameters; 3) Improved parsing code for --mysqld-args parameters. Now it correctly processes the sequence "--" after the name of the one-letter option; 4) Checking the secret signature during joiner authentication is made independent of presence of bash (as a unix shell) in the system and diff utility no longer needed to check certificates compliance; 5) All directories that are necessary for the correct placement of various logs are automatically created by SST scripts in advance (before running mariabackup on the joiner node); 6) Removal of old binary logs on joiner is done using the binlog index (if it exists) (not only by fixed pattern that based on the current binlog name, as before); 7) Paths for placing binary logs are correctly processed if they are set as relative paths (to the datadir); 8) SST scripts are made even more resistant to spaces in filenames (now for binlogs); 9) In case of failure, SST scripts now always end with an exit code other than zero; 10) SST script for rsync now correctly create a tar file with the binlogs, even if the paths to them (in the binlog index file) are specified as a mix of absolute and relative paths, and even if they do not match with the datadir path specified in the current configuration settings.

MDEV-25818: RSYNC SST failed due to busy port This commit reduces the likelihood of getting a busy port on quick restarts with rsync SST (problem MDEV-25818) and fixes a number of other flaws in SST scripts, adds new functionality, and also synchronizes the xtrabackup-v2 script with the mariabackup script (the latter applies only to the 10.2 branch): 1) SST via rsync: rsync and stunnel does not always get the right time to complete by correctly handling SIGTERM. These utilities are now given more time to complete normally (via normal SIGTERM processing) before we move on to using "kill -9"; 2) SST via rsync: attempts to terminate an rsync or stunnel process (via "kill" utility) are only made if it did not terminated on its own; 3) SST via rsync: if a combination of stunnel and rsync is used, then we need to wait for both utilities to finish or stop, not just one of them; 4) The config file and pid file for stunnel are now deleted after successful completion of SST on the donor node; 5) The configs and pid files from rsync and stunnel should not be deleted unless these utilities succeed (or are sucessfully terminated) on the joiner node; 6) The configs and pid files now excluded from transfer via rsync; 7) Spaces in paths are now valid for config files as well (when used with SST via rsync or mariabackup / xtrabackup[-v2]); 8) SST via mariabackup: added preliminary verification of keys and certificates that are used when establishing a connection using SSL (to avoid long timeouts and improve diagnostics) - by analogy with how it is done for the xtrabackup-v2 (plus check for CA file), while that check is skipped if the user does not have openssl installed (or does not have diff utility); 9) Added backup-threads=<n> configuration option which adds "--parallel=<n>" for mariabackup / xtrabackup at backup and move-back stages; 10) Added encrypt-threads and encrypt-chunk-size configuration options for xbcrypt management (when xbcrypt is used); 11) Small optimization: checking the socat version and adding a file with parameters for 2048-bit Diffie-Hellman (if necessary) is done only if the user has not specified "dhparam=" in the "sockopt" option value; 12) SST via rsync now supports "backup-threads" configuration option (in server-related sections or in the "[sst]"); 13) Determining the number of available processors is now supported for FreeBSD + mariabackup/xtrabackup: before that we might have problems with "--compact" (rebuild indexes) or qpress on FreeBSD; 14) The check_pid() function should not raise an error state in the rare cases when the pid file was created, but it is empty, or if it is deleted right during the check, or when zero is read from the pid file; 15) Iproved templates that are used to check if a requested socket is "listening" when using the ss utility; 16) Shortened some other templates for socket state utilities; 17) Temporary files created by mariabackup / xtrabackup are moved to a separate subdirectory inside tmpdir (so they don't get mixed with other temporary files, which can make debugging more difficult); 18) 10.2 only: the script for SST via xtrabackup-v2 has been brought in full compliance with all the bugfixes made for mariabackup (as it previously contained many flaws compared to the updated script for mariabackup).

MDEV-24962: Galera SST innobackupex-move ignores Environment settings After switching to the new mariabackup interface (instead of the outdated innobackupex interface, which is supported for compatibility), we need to explicitly pass a path to the datadir directory as a parameter, since in the new interface the value of this option is not automatically set in such a way that it always matches the SST/IST logic. This commit adds passing this option as an explicit parameter to mariabackup. This commit also removed unnecessary options that are not used and not supported by mariabackup. Also, numerous flaws in the common wsrep_sst_common script have been fixed: 1) There are many bash-specific constructs in the script that may not be supported by other interpreters, which can lead to the most unexpected errors during SST, because failures in the interpretation of bash-specific constructs lead to incorrect parsing of arguments; 2) There is parse_cnf() function which is often called by other scripts for the "mysqld" or "--mysqld" group, but it does not take into account the default group suffix, which leads to reading values only from the default group, which then leads to errors due to reading the default values instead of the values for a specific group; 3) Some options such as --user, --innodb-data-home-dir or --datadir are not removed from the --mysqld-args list, although they are processed inside scripts (and passing of these options funther may cause problems for mariabackup); 4) If an argument that the script understands is present in the --mysqld-args list twice, then this causes SST to fail, instead of reading the most recent value; 5) The "--host" parameter is technically still supported among the arguments of the SST scripts, but in reality scripts do not work with it as expected, especially if it has an IPv6 address; 6) If the port number is absent in the --address parameter value, but the port number is explicitly passed through the --port argument, then the scripts for mariabackup and xtrabackup-v2 fail; 7) If a new address interface is used (with the --address parameter), then automatic default port substitution is not performed, although it is supported for the legacy --host/--port interface. 8) If there are spaces in the parameter values after --mysqld_args, then their further transfer does not occur correctly, which causes mariabackup to fail during SST - the space splits the argument in such a way that it breaks the parsing of the following parameters; 9) If most of the parameters that are names or paths to the files or directories contain spaces, then SST scripts fail in an unpredictable way due to incorrect variable substitutions; 10) If the --log-bin option is passed among the arguments of myqlds (--mysqld-args) without a parameter, and the --binlog option is not specified, then the script cannot substitute the default name for binlog and cannot construct binlog name using the --log-basename argument (which is against server specifications); 11) Tail slashes are not removed from the directory names, which, upon further substitution, leads to the appearance of a double slash in the file paths; 12) The explicit --binlog parameter (which is now always transmitted from the server side) and the "hidden" --log-bin parameter in the list of arguments after --mysqld-args are perceived as two different parameters in different parts of the scripts, and if they are do not match for some reason, this will lead to failures during SST; Also, all new changes from the 10.6 branch have been migrated here, including the latest pull requests for authentication (only the part that concerns SST scripts). It also fixes dozens of other bugs in all SST scripts.

MDEV-24097: galera[_3nodes] suite tests in MTR sporadically fails This is the first part of the fixes for MDEV-24097. This commit contains the fixes for instability when testing Galera and when restarting nodes quickly: 1) Protection against a "stuck" old SST process during the execution of the new SST (after restarting the node) is now implemented for mariabackup / xtrabackup, which should help to avoid almost all conflicts due to the use of the same ports - both during testing with mtr, so and when restarting nodes quickly in a production environment. 2) Added more protection to scripts against unexpected return of the rc != 0 (in the commands for deleting temporary files, etc). 3) Added protection against unexpected crashes during binlog transfer (in SST scripts for rsync). 4) Spaces and some special characters in binlog filenames shouldn't be a problem now (at the script level). 5) Daemon process termination tracking has been made more robust against crashes due to unexpected termination of the previous SST process while new scripts are running. 6) Reading ssl encryption parameters has been moved from specific SST scripts to a common wsrep_sst_common.sh script, which allows unified error handling, unified diagnostics and simplifies script revisions in the future. 7) Improved diagnostics of errors related to the use of openssl. 8) Corrections have been made for xtrabackup-v2 (both in tests and in the script code) that restore the work of xtrabackup with updated versions of innodb. 9) Fixed some tests for galera_3nodes, although the complete solution for the problem of starting three nodes at the same time on fast machines will be done in a separate commit. No additional tests are required as this commit fixes problems with existing tests.

MDEV-23580: WSREP_SST: [ERROR] rsync daemon port has been taken This commit contains a large set of further bug fixes and improvements to SST scripts for Galera, continuing the work that was started in MDEV-24962 to make SST scripts work smoothly in different network configurations (especially using ipv6) and with different environment settings: 1) The ipv6 addresses were incorrectly handled in the SST script for rsync (incorrect address substitution for establishing a connection, incorrect address substitution for bind, and so on); 2) Checking the locality of the ip-address in SST scripts did not support ipv6 addresses (such as "[::1]"), which were falsely identified as non-local ip, which further did not allow running two SSTs on different local addresses on the same machine. On the other hand, this bug masked some other errors (related to handling ipv6 addresses); 3) The code for checking the locality of the ip address was different in the SST scripts for rsync and for mysqldump, with individual flaws. This code is now made common and moved to wsrep_sst_common; 4) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) in the wait_for_listen() and check_pid_and_port() functions did not process ipv6 addresses correctly in all cases (not for all branches); 5) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) in the wait_for_listen() and check_pid_and_port() functions for some code branches could give a false positive result due to the textual match of prefixes in the port number and/or PID of the process; 6) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) was supported through different utilities in SST scripts for mariabackup and for rsync, and with various minor flaws in the code. Now the code is still different in these scripts, but it supports a common set of utilities (lsof, ss, sockstat) and is synchronized across patterns that used to check the output of these utilities; 7) In SST via mariabackup, the signal about readiness to receive data is sometimes sent too early - immediately after listen(), and not after accept() (which are called by socat or netcat utility). 8) Checking availability of the some options of some utilities was done using the grep pattern, which easily gives false positives; 9) Common name (CN) for local addresses, if not explicitly specified, is now always replaced to "localhost" to avoid the need to generate many separate certificates for local addresses of one machine and not to depend on which the local address is currently used in test (ipv4 or ipv6, etc.); 10) In tests galera_sst_mariabackup_encrypt_with_key_server and galera_sst_rsync_encrypt_with_key_server the correct certificate is selected to avoid commonname (CN) mismatch problems; 11) Further refactoring to protect against spaces in file names. 12) Further general refactoring to eliminate bash-specific constructs or to improve code readability; 13) The code for setting options for the nc (netcat) utility was different in different scripts for SST - now it is made identical. 14) Fixed long-time broken encryption via xbcrypt in combination with mariabackup and added support for key-based encryption via openssl utility, which is now enabled by default for encrypt=1 mode (this default mode can be changed using a new configuration file option "encypt-format=openssl|xbcrypt", which can be placed in the [mysqld], [sst] or in the [xtrabackup] section) - this change will allow us to use and to test the encypt=1 encryption without installing non-standard third-party utilities.

MDEV-24097: galera[_3nodes] suite tests in MTR sporadically fails This is the first part of the fixes for MDEV-24097. This commit contains the fixes for instability when testing Galera and when restarting nodes quickly: 1) Protection against a "stuck" old SST process during the execution of the new SST (after restarting the node) is now implemented for mariabackup / xtrabackup, which should help to avoid almost all conflicts due to the use of the same ports - both during testing with mtr, so and when restarting nodes quickly in a production environment. 2) Added more protection to scripts against unexpected return of the rc != 0 (in the commands for deleting temporary files, etc). 3) Added protection against unexpected crashes during binlog transfer (in SST scripts for rsync). 4) Spaces and some special characters in binlog filenames shouldn't be a problem now (at the script level). 5) Daemon process termination tracking has been made more robust against crashes due to unexpected termination of the previous SST process while new scripts are running. 6) Reading ssl encryption parameters has been moved from specific SST scripts to a common wsrep_sst_common.sh script, which allows unified error handling, unified diagnostics and simplifies script revisions in the future. 7) Improved diagnostics of errors related to the use of openssl. 8) Corrections have been made for xtrabackup-v2 (both in tests and in the script code) that restore the work of xtrabackup with updated versions of innodb. 9) Fixed some tests for galera_3nodes, although the complete solution for the problem of starting three nodes at the same time on fast machines will be done in a separate commit. No additional tests are required as this commit fixes problems with existing tests.

MDEV-25818: RSYNC SST failed due to busy port This commit reduces the likelihood of getting a busy port on quick restarts with rsync SST (problem MDEV-25818) and fixes a number of other flaws in SST scripts, adds new functionality, and also synchronizes the xtrabackup-v2 script with the mariabackup script (the latter applies only to the 10.2 branch): 1) SST via rsync: rsync and stunnel does not always get the right time to complete by correctly handling SIGTERM. These utilities are now given more time to complete normally (via normal SIGTERM processing) before we move on to using "kill -9"; 2) SST via rsync: attempts to terminate an rsync or stunnel process (via "kill" utility) are only made if it did not terminated on its own; 3) SST via rsync: if a combination of stunnel and rsync is used, then we need to wait for both utilities to finish or stop, not just one of them; 4) The config file and pid file for stunnel are now deleted after successful completion of SST on the donor node; 5) The configs and pid files from rsync and stunnel should not be deleted unless these utilities succeed (or are sucessfully terminated) on the joiner node; 6) The configs and pid files now excluded from transfer via rsync; 7) Spaces in paths are now valid for config files as well (when used with SST via rsync or mariabackup / xtrabackup[-v2]); 8) SST via mariabackup: added preliminary verification of keys and certificates that are used when establishing a connection using SSL (to avoid long timeouts and improve diagnostics) - by analogy with how it is done for the xtrabackup-v2 (plus check for CA file), while that check is skipped if the user does not have openssl installed (or does not have diff utility); 9) Added backup-threads=<n> configuration option which adds "--parallel=<n>" for mariabackup / xtrabackup at backup and move-back stages; 10) Added encrypt-threads and encrypt-chunk-size configuration options for xbcrypt management (when xbcrypt is used); 11) Small optimization: checking the socat version and adding a file with parameters for 2048-bit Diffie-Hellman (if necessary) is done only if the user has not specified "dhparam=" in the "sockopt" option value; 12) SST via rsync now supports "backup-threads" configuration option (in server-related sections or in the "[sst]"); 13) Determining the number of available processors is now supported for FreeBSD + mariabackup/xtrabackup: before that we might have problems with "--compact" (rebuild indexes) or qpress on FreeBSD; 14) The check_pid() function should not raise an error state in the rare cases when the pid file was created, but it is empty, or if it is deleted right during the check, or when zero is read from the pid file; 15) Iproved templates that are used to check if a requested socket is "listening" when using the ss utility; 16) Shortened some other templates for socket state utilities; 17) Temporary files created by mariabackup / xtrabackup are moved to a separate subdirectory inside tmpdir (so they don't get mixed with other temporary files, which can make debugging more difficult); 18) 10.2 only: the script for SST via xtrabackup-v2 has been brought in full compliance with all the bugfixes made for mariabackup (as it previously contained many flaws compared to the updated script for mariabackup).

MDEV-24962: Galera SST innobackupex-move ignores Environment settings After switching to the new mariabackup interface (instead of the outdated innobackupex interface, which is supported for compatibility), we need to explicitly pass a path to the datadir directory as a parameter, since in the new interface the value of this option is not automatically set in such a way that it always matches the SST/IST logic. This commit adds passing this option as an explicit parameter to mariabackup. This commit also removed unnecessary options that are not used and not supported by mariabackup. Also, numerous flaws in the common wsrep_sst_common script have been fixed: 1) There are many bash-specific constructs in the script that may not be supported by other interpreters, which can lead to the most unexpected errors during SST, because failures in the interpretation of bash-specific constructs lead to incorrect parsing of arguments; 2) There is parse_cnf() function which is often called by other scripts for the "mysqld" or "--mysqld" group, but it does not take into account the default group suffix, which leads to reading values only from the default group, which then leads to errors due to reading the default values instead of the values for a specific group; 3) Some options such as --user, --innodb-data-home-dir or --datadir are not removed from the --mysqld-args list, although they are processed inside scripts (and passing of these options funther may cause problems for mariabackup); 4) If an argument that the script understands is present in the --mysqld-args list twice, then this causes SST to fail, instead of reading the most recent value; 5) The "--host" parameter is technically still supported among the arguments of the SST scripts, but in reality scripts do not work with it as expected, especially if it has an IPv6 address; 6) If the port number is absent in the --address parameter value, but the port number is explicitly passed through the --port argument, then the scripts for mariabackup and xtrabackup-v2 fail; 7) If a new address interface is used (with the --address parameter), then automatic default port substitution is not performed, although it is supported for the legacy --host/--port interface. 8) If there are spaces in the parameter values after --mysqld_args, then their further transfer does not occur correctly, which causes mariabackup to fail during SST - the space splits the argument in such a way that it breaks the parsing of the following parameters; 9) If most of the parameters that are names or paths to the files or directories contain spaces, then SST scripts fail in an unpredictable way due to incorrect variable substitutions; 10) If the --log-bin option is passed among the arguments of myqlds (--mysqld-args) without a parameter, and the --binlog option is not specified, then the script cannot substitute the default name for binlog and cannot construct binlog name using the --log-basename argument (which is against server specifications); 11) Tail slashes are not removed from the directory names, which, upon further substitution, leads to the appearance of a double slash in the file paths; 12) The explicit --binlog parameter (which is now always transmitted from the server side) and the "hidden" --log-bin parameter in the list of arguments after --mysqld-args are perceived as two different parameters in different parts of the scripts, and if they are do not match for some reason, this will lead to failures during SST; Also, all new changes from the 10.6 branch have been migrated here, including the latest pull requests for authentication (only the part that concerns SST scripts). It also fixes dozens of other bugs in all SST scripts.

This code is now made common and moved to wsrep_sst_common; 4) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) in the wait_for_listen() and check_pid_and_port() functions did not process ipv6 addresses correctly in all cases (not for all branches); 5) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) in the wait_for_listen() and check_pid_and_port() functions for some code branches could give a false positive result due to the textual match of prefixes in the port number and/or PID of the process; 6) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) was supported through different utilities in SST scripts for mariabackup and for rsync, and with various minor flaws in the code. Now the code is still different in these scripts, but it supports a common set of utilities (lsof, ss, sockstat) and is synchronized across patterns that used to check the output of these utilities; 7) In SST via mariabackup, the signal about readiness to receive data is sometimes sent too early - immediately after listen(), and not after accept() (which are called by socat or netcat utility). 8) Checking availability of the some options of some utilities was done using the grep pattern, which easily gives false positives; 9) Common name (CN) for local addresses, if not explicitly specified, is now always replaced to "localhost" to avoid the need to generate many separate certificates for local addresses of one machine and not to depend on which the local address is currently used in test (ipv4 or ipv6, etc.); 10) In tests galera_sst_mariabackup_encrypt_with_key_server and galera_sst_rsync_encrypt_with_key_server the correct certificate is selected to avoid commonname (CN) mismatch problems; 11) Further refactoring to protect against spaces in file names. 12) Further general refactoring to eliminate bash-specific constructs or to improve code readability; 13) The code for setting options for the nc (netcat) utility was different in different scripts for SST - now it is made identical. 14) Fixed long-time broken encryption via xbcrypt in combination with mariabackup and added support for key-based encryption via openssl utility, which is now enabled by default for encrypt=1 mode (this default mode can be changed using a new configuration file option "encypt-format=openssl|xbcrypt", which can be placed in the [mysqld], [sst] or in the [xtrabackup] section) - this change will allow us to use and to test the encypt=1 encryption without installing non-standard third-party utilities.

MDEV-24962: Galera SST innobackupex-move ignores Environment settings After switching to the new mariabackup interface (instead of the outdated innobackupex interface, which is supported for compatibility), we need to explicitly pass a path to the datadir directory as a parameter, since in the new interface the value of this option is not automatically set in such a way that it always matches the SST/IST logic. This commit adds passing this option as an explicit parameter to mariabackup. This commit also removed unnecessary options that are not used and not supported by mariabackup. Also, numerous flaws in the common wsrep_sst_common script have been fixed: 1) There are many bash-specific constructs in the script that may not be supported by other interpreters, which can lead to the most unexpected errors during SST, because failures in the interpretation of bash-specific constructs lead to incorrect parsing of arguments; 2) There is parse_cnf() function which is often called by other scripts for the "mysqld" or "--mysqld" group, but it does not take into account the default group suffix, which leads to reading values only from the default group, which then leads to errors due to reading the default values instead of the values for a specific group; 3) Some options such as --user, --innodb-data-home-dir or --datadir are not removed from the --mysqld-args list, although they are processed inside scripts (and passing of these options funther may cause problems for mariabackup); 4) If an argument that the script understands is present in the --mysqld-args list twice, then this causes SST to fail, instead of reading the most recent value; 5) The "--host" parameter is technically still supported among the arguments of the SST scripts, but in reality scripts do not work with it as expected, especially if it has an IPv6 address; 6) If the port number is absent in the --address parameter value, but the port number is explicitly passed through the --port argument, then the scripts for mariabackup and xtrabackup-v2 fail; 7) If a new address interface is used (with the --address parameter), then automatic default port substitution is not performed, although it is supported for the legacy --host/--port interface. 8) If there are spaces in the parameter values after --mysqld_args, then their further transfer does not occur correctly, which causes mariabackup to fail during SST - the space splits the argument in such a way that it breaks the parsing of the following parameters; 9) If most of the parameters that are names or paths to the files or directories contain spaces, then SST scripts fail in an unpredictable way due to incorrect variable substitutions; 10) If the --log-bin option is passed among the arguments of myqlds (--mysqld-args) without a parameter, and the --binlog option is not specified, then the script cannot substitute the default name for binlog and cannot construct binlog name using the --log-basename argument (which is against server specifications); 11) Tail slashes are not removed from the directory names, which, upon further substitution, leads to the appearance of a double slash in the file paths; 12) The explicit --binlog parameter (which is now always transmitted from the server side) and the "hidden" --log-bin parameter in the list of arguments after --mysqld-args are perceived as two different parameters in different parts of the scripts, and if they are do not match for some reason, this will lead to failures during SST; Also, all new changes from the 10.6 branch have been migrated here, including the latest pull requests for authentication (only the part that concerns SST scripts). It also fixes dozens of other bugs in all SST scripts.

MDEV-25818: RSYNC SST failed due to busy port This commit reduces the likelihood of getting a busy port on quick restarts with rsync SST (problem MDEV-25818) and fixes a number of other flaws in SST scripts, adds new functionality, and also synchronizes the xtrabackup-v2 script with the mariabackup script (the latter applies only to the 10.2 branch): 1) SST via rsync: rsync and stunnel does not always get the right time to complete by correctly handling SIGTERM. These utilities are now given more time to complete normally (via normal SIGTERM processing) before we move on to using "kill -9"; 2) SST via rsync: attempts to terminate an rsync or stunnel process (via "kill" utility) are only made if it did not terminated on its own; 3) SST via rsync: if a combination of stunnel and rsync is used, then we need to wait for both utilities to finish or stop, not just one of them; 4) The config file and pid file for stunnel are now deleted after successful completion of SST on the donor node; 5) The configs and pid files from rsync and stunnel should not be deleted unless these utilities succeed (or are sucessfully terminated) on the joiner node; 6) The configs and pid files now excluded from transfer via rsync; 7) Spaces in paths are now valid for config files as well (when used with SST via rsync or mariabackup / xtrabackup[-v2]); 8) SST via mariabackup: added preliminary verification of keys and certificates that are used when establishing a connection using SSL (to avoid long timeouts and improve diagnostics) - by analogy with how it is done for the xtrabackup-v2 (plus check for CA file), while that check is skipped if the user does not have openssl installed (or does not have diff utility); 9) Added backup-threads=<n> configuration option which adds "--parallel=<n>" for mariabackup / xtrabackup at backup and move-back stages; 10) Added encrypt-threads and encrypt-chunk-size configuration options for xbcrypt management (when xbcrypt is used); 11) Small optimization: checking the socat version and adding a file with parameters for 2048-bit Diffie-Hellman (if necessary) is done only if the user has not specified "dhparam=" in the "sockopt" option value; 12) SST via rsync now supports "backup-threads" configuration option (in server-related sections or in the "[sst]"); 13) Determining the number of available processors is now supported for FreeBSD + mariabackup/xtrabackup: before that we might have problems with "--compact" (rebuild indexes) or qpress on FreeBSD; 14) The check_pid() function should not raise an error state in the rare cases when the pid file was created, but it is empty, or if it is deleted right during the check, or when zero is read from the pid file; 15) Iproved templates that are used to check if a requested socket is "listening" when using the ss utility; 16) Shortened some other templates for socket state utilities; 17) Temporary files created by mariabackup / xtrabackup are moved to a separate subdirectory inside tmpdir (so they don't get mixed with other temporary files, which can make debugging more difficult); 18) 10.2 only: the script for SST via xtrabackup-v2 has been brought in full compliance with all the bugfixes made for mariabackup (as it previously contained many flaws compared to the updated script for mariabackup).

MDEV-24962: Galera SST innobackupex-move ignores Environment settings After switching to the new mariabackup interface (instead of the outdated innobackupex interface, which is supported for compatibility), we need to explicitly pass a path to the datadir directory as a parameter, since in the new interface the value of this option is not automatically set in such a way that it always matches the SST/IST logic. This commit adds passing this option as an explicit parameter to mariabackup. This commit also removed unnecessary options that are not used and not supported by mariabackup. Also, numerous flaws in the common wsrep_sst_common script have been fixed: 1) There are many bash-specific constructs in the script that may not be supported by other interpreters, which can lead to the most unexpected errors during SST, because failures in the interpretation of bash-specific constructs lead to incorrect parsing of arguments; 2) There is parse_cnf() function which is often called by other scripts for the "mysqld" or "--mysqld" group, but it does not take into account the default group suffix, which leads to reading values only from the default group, which then leads to errors due to reading the default values instead of the values for a specific group; 3) Some options such as --user, --innodb-data-home-dir or --datadir are not removed from the --mysqld-args list, although they are processed inside scripts (and passing of these options funther may cause problems for mariabackup); 4) If an argument that the script understands is present in the --mysqld-args list twice, then this causes SST to fail, instead of reading the most recent value; 5) The "--host" parameter is technically still supported among the arguments of the SST scripts, but in reality scripts do not work with it as expected, especially if it has an IPv6 address; 6) If the port number is absent in the --address parameter value, but the port number is explicitly passed through the --port argument, then the scripts for mariabackup and xtrabackup-v2 fail; 7) If a new address interface is used (with the --address parameter), then automatic default port substitution is not performed, although it is supported for the legacy --host/--port interface. 8) If there are spaces in the parameter values after --mysqld_args, then their further transfer does not occur correctly, which causes mariabackup to fail during SST - the space splits the argument in such a way that it breaks the parsing of the following parameters; 9) If most of the parameters that are names or paths to the files or directories contain spaces, then SST scripts fail in an unpredictable way due to incorrect variable substitutions; 10) If the --log-bin option is passed among the arguments of myqlds (--mysqld-args) without a parameter, and the --binlog option is not specified, then the script cannot substitute the default name for binlog and cannot construct binlog name using the --log-basename argument (which is against server specifications); 11) Tail slashes are not removed from the directory names, which, upon further substitution, leads to the appearance of a double slash in the file paths; 12) The explicit --binlog parameter (which is now always transmitted from the server side) and the "hidden" --log-bin parameter in the list of arguments after --mysqld-args are perceived as two different parameters in different parts of the scripts, and if they are do not match for some reason, this will lead to failures during SST; Also, all new changes from the 10.6 branch have been migrated here, including the latest pull requests for authentication (only the part that concerns SST scripts). It also fixes dozens of other bugs in all SST scripts.

MDEV-23580: WSREP_SST: [ERROR] rsync daemon port has been taken This commit contains a large set of further bug fixes and improvements to SST scripts for Galera, continuing the work that was started in MDEV-24962 to make SST scripts work smoothly in different network configurations (especially using ipv6) and with different environment settings: 1) The ipv6 addresses were incorrectly handled in the SST script for rsync (incorrect address substitution for establishing a connection, incorrect address substitution for bind, and so on); 2) Checking the locality of the ip-address in SST scripts did not support ipv6 addresses (such as "[::1]"), which were falsely identified as non-local ip, which further did not allow running two SSTs on different local addresses on the same machine. On the other hand, this bug masked some other errors (related to handling ipv6 addresses); 3) The code for checking the locality of the ip address was different in the SST scripts for rsync and for mysqldump, with individual flaws. This code is now made common and moved to wsrep_sst_common; 4) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) in the wait_for_listen() and check_pid_and_port() functions did not process ipv6 addresses correctly in all cases (not for all branches); 5) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) in the wait_for_listen() and check_pid_and_port() functions for some code branches could give a false positive result due to the textual match of prefixes in the port number and/or PID of the process; 6) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) was supported through different utilities in SST scripts for mariabackup and for rsync, and with various minor flaws in the code. Now the code is still different in these scripts, but it supports a common set of utilities (lsof, ss, sockstat) and is synchronized across patterns that used to check the output of these utilities; 7) In SST via mariabackup, the signal about readiness to receive data is sometimes sent too early - immediately after listen(), and not after accept() (which are called by socat or netcat utility). 8) Checking availability of the some options of some utilities was done using the grep pattern, which easily gives false positives; 9) Common name (CN) for local addresses, if not explicitly specified, is now always replaced to "localhost" to avoid the need to generate many separate certificates for local addresses of one machine and not to depend on which the local address is currently used in test (ipv4 or ipv6, etc.); 10) In tests galera_sst_mariabackup_encrypt_with_key_server and galera_sst_rsync_encrypt_with_key_server the correct certificate is selected to avoid commonname (CN) mismatch problems; 11) Further refactoring to protect against spaces in file names. 12) Further general refactoring to eliminate bash-specific constructs or to improve code readability; 13) The code for setting options for the nc (netcat) utility was different in different scripts for SST - now it is made identical. 14) Fixed long-time broken encryption via xbcrypt in combination with mariabackup and added support for key-based encryption via openssl utility, which is now enabled by default for encrypt=1 mode (this default mode can be changed using a new configuration file option "encypt-format=openssl|xbcrypt", which can be placed in the [mysqld], [sst] or in the [xtrabackup] section) - this change will allow us to use and to test the encypt=1 encryption without installing non-standard third-party utilities.

MDEV-25818: RSYNC SST failed due to busy port This commit reduces the likelihood of getting a busy port on quick restarts with rsync SST (problem MDEV-25818) and fixes a number of other flaws in SST scripts, adds new functionality, and also synchronizes the xtrabackup-v2 script with the mariabackup script (the latter applies only to the 10.2 branch): 1) SST via rsync: rsync and stunnel does not always get the right time to complete by correctly handling SIGTERM. These utilities are now given more time to complete normally (via normal SIGTERM processing) before we move on to using "kill -9"; 2) SST via rsync: attempts to terminate an rsync or stunnel process (via "kill" utility) are only made if it did not terminated on its own; 3) SST via rsync: if a combination of stunnel and rsync is used, then we need to wait for both utilities to finish or stop, not just one of them; 4) The config file and pid file for stunnel are now deleted after successful completion of SST on the donor node; 5) The configs and pid files from rsync and stunnel should not be deleted unless these utilities succeed (or are sucessfully terminated) on the joiner node; 6) The configs and pid files now excluded from transfer via rsync; 7) Spaces in paths are now valid for config files as well (when used with SST via rsync or mariabackup / xtrabackup[-v2]); 8) SST via mariabackup: added preliminary verification of keys and certificates that are used when establishing a connection using SSL (to avoid long timeouts and improve diagnostics) - by analogy with how it is done for the xtrabackup-v2 (plus check for CA file), while that check is skipped if the user does not have openssl installed (or does not have diff utility); 9) Added backup-threads=<n> configuration option which adds "--parallel=<n>" for mariabackup / xtrabackup at backup and move-back stages; 10) Added encrypt-threads and encrypt-chunk-size configuration options for xbcrypt management (when xbcrypt is used); 11) Small optimization: checking the socat version and adding a file with parameters for 2048-bit Diffie-Hellman (if necessary) is done only if the user has not specified "dhparam=" in the "sockopt" option value; 12) SST via rsync now supports "backup-threads" configuration option (in server-related sections or in the "[sst]"); 13) Determining the number of available processors is now supported for FreeBSD + mariabackup/xtrabackup: before that we might have problems with "--compact" (rebuild indexes) or qpress on FreeBSD; 14) The check_pid() function should not raise an error state in the rare cases when the pid file was created, but it is empty, or if it is deleted right during the check, or when zero is read from the pid file; 15) Iproved templates that are used to check if a requested socket is "listening" when using the ss utility; 16) Shortened some other templates for socket state utilities; 17) Temporary files created by mariabackup / xtrabackup are moved to a separate subdirectory inside tmpdir (so they don't get mixed with other temporary files, which can make debugging more difficult); 18) 10.2 only: the script for SST via xtrabackup-v2 has been brought in full compliance with all the bugfixes made for mariabackup (as it previously contained many flaws compared to the updated script for mariabackup).

These utilities are now given more time to complete normally (via normal SIGTERM processing) before we move on to using "kill -9"; 2) SST via rsync: attempts to terminate an rsync or stunnel process (via "kill" utility) are only made if it did not terminated on its own; 3) SST via rsync: if a combination of stunnel and rsync is used, then we need to wait for both utilities to finish or stop, not just one of them; 4) The config file and pid file for stunnel are now deleted after successful completion of SST on the donor node; 5) The configs and pid files from rsync and stunnel should not be deleted unless these utilities succeed (or are sucessfully terminated) on the joiner node; 6) The configs and pid files now excluded from transfer via rsync; 7) Spaces in paths are now valid for config files as well (when used with SST via rsync or mariabackup / xtrabackup[-v2]); 8) SST via mariabackup: added preliminary verification of keys and certificates that are used when establishing a connection using SSL (to avoid long timeouts and improve diagnostics) - by analogy with how it is done for the xtrabackup-v2 (plus check for CA file), while that check is skipped if the user does not have openssl installed (or does not have diff utility); 9) Added backup-threads=<n> configuration option which adds "--parallel=<n>" for mariabackup / xtrabackup at backup and move-back stages; 10) Added encrypt-threads and encrypt-chunk-size configuration options for xbcrypt management (when xbcrypt is used); 11) Small optimization: checking the socat version and adding a file with parameters for 2048-bit Diffie-Hellman (if necessary) is done only if the user has not specified "dhparam=" in the "sockopt" option value; 12) SST via rsync now supports "backup-threads" configuration option (in server-related sections or in the "[sst]"); 13) Determining the number of available processors is now supported for FreeBSD + mariabackup/xtrabackup: before that we might have problems with "--compact" (rebuild indexes) or qpress on FreeBSD; 14) The check_pid() function should not raise an error state in the rare cases when the pid file was created, but it is empty, or if it is deleted right during the check, or when zero is read from the pid file; 15) Iproved templates that are used to check if a requested socket is "listening" when using the ss utility; 16) Shortened some other templates for socket state utilities; 17) Temporary files created by mariabackup / xtrabackup are moved to a separate subdirectory inside tmpdir (so they don't get mixed with other temporary files, which can make debugging more difficult); 18) 10.2 only: the script for SST via xtrabackup-v2 has been brought in full compliance with all the bugfixes made for mariabackup (as it previously contained many flaws compared to the updated script for mariabackup).

MDEV-24097: galera[_3nodes] suite tests in MTR sporadically fails This is the first part of the fixes for MDEV-24097. This commit contains the fixes for instability when testing Galera and when restarting nodes quickly: 1) Protection against a "stuck" old SST process during the execution of the new SST (after restarting the node) is now implemented for mariabackup / xtrabackup, which should help to avoid almost all conflicts due to the use of the same ports - both during testing with mtr, so and when restarting nodes quickly in a production environment. 2) Added more protection to scripts against unexpected return of the rc != 0 (in the commands for deleting temporary files, etc). 3) Added protection against unexpected crashes during binlog transfer (in SST scripts for rsync). 4) Spaces and some special characters in binlog filenames shouldn't be a problem now (at the script level). 5) Daemon process termination tracking has been made more robust against crashes due to unexpected termination of the previous SST process while new scripts are running. 6) Reading ssl encryption parameters has been moved from specific SST scripts to a common wsrep_sst_common.sh script, which allows unified error handling, unified diagnostics and simplifies script revisions in the future. 7) Improved diagnostics of errors related to the use of openssl. 8) Corrections have been made for xtrabackup-v2 (both in tests and in the script code) that restore the work of xtrabackup with updated versions of innodb. 9) Fixed some tests for galera_3nodes, although the complete solution for the problem of starting three nodes at the same time on fast machines will be done in a separate commit. No additional tests are required as this commit fixes problems with existing tests.

MDEV-24962: Galera SST innobackupex-move ignores Environment settings After switching to the new mariabackup interface (instead of the outdated innobackupex interface, which is supported for compatibility), we need to explicitly pass a path to the datadir directory as a parameter, since in the new interface the value of this option is not automatically set in such a way that it always matches the SST/IST logic. This commit adds passing this option as an explicit parameter to mariabackup. This commit also removed unnecessary options that are not used and not supported by mariabackup. Also, numerous flaws in the common wsrep_sst_common script have been fixed: 1) There are many bash-specific constructs in the script that may not be supported by other interpreters, which can lead to the most unexpected errors during SST, because failures in the interpretation of bash-specific constructs lead to incorrect parsing of arguments; 2) There is parse_cnf() function which is often called by other scripts for the "mysqld" or "--mysqld" group, but it does not take into account the default group suffix, which leads to reading values only from the default group, which then leads to errors due to reading the default values instead of the values for a specific group; 3) Some options such as --user, --innodb-data-home-dir or --datadir are not removed from the --mysqld-args list, although they are processed inside scripts (and passing of these options funther may cause problems for mariabackup); 4) If an argument that the script understands is present in the --mysqld-args list twice, then this causes SST to fail, instead of reading the most recent value; 5) The "--host" parameter is technically still supported among the arguments of the SST scripts, but in reality scripts do not work with it as expected, especially if it has an IPv6 address; 6) If the port number is absent in the --address parameter value, but the port number is explicitly passed through the --port argument, then the scripts for mariabackup and xtrabackup-v2 fail; 7) If a new address interface is used (with the --address parameter), then automatic default port substitution is not performed, although it is supported for the legacy --host/--port interface. 8) If there are spaces in the parameter values after --mysqld_args, then their further transfer does not occur correctly, which causes mariabackup to fail during SST - the space splits the argument in such a way that it breaks the parsing of the following parameters; 9) If most of the parameters that are names or paths to the files or directories contain spaces, then SST scripts fail in an unpredictable way due to incorrect variable substitutions; 10) If the --log-bin option is passed among the arguments of myqlds (--mysqld-args) without a parameter, and the --binlog option is not specified, then the script cannot substitute the default name for binlog and cannot construct binlog name using the --log-basename argument (which is against server specifications); 11) Tail slashes are not removed from the directory names, which, upon further substitution, leads to the appearance of a double slash in the file paths; 12) The explicit --binlog parameter (which is now always transmitted from the server side) and the "hidden" --log-bin parameter in the list of arguments after --mysqld-args are perceived as two different parameters in different parts of the scripts, and if they are do not match for some reason, this will lead to failures during SST; Also, all new changes from the 10.6 branch have been migrated here, including the latest pull requests for authentication (only the part that concerns SST scripts). It also fixes dozens of other bugs in all SST scripts.

MDEV-23580: WSREP_SST: [ERROR] rsync daemon port has been taken This commit contains a large set of further bug fixes and improvements to SST scripts for Galera, continuing the work that was started in MDEV-24962 to make SST scripts work smoothly in different network configurations (especially using ipv6) and with different environment settings: 1) The ipv6 addresses were incorrectly handled in the SST script for rsync (incorrect address substitution for establishing a connection, incorrect address substitution for bind, and so on); 2) Checking the locality of the ip-address in SST scripts did not support ipv6 addresses (such as "[::1]"), which were falsely identified as non-local ip, which further did not allow running two SSTs on different local addresses on the same machine. On the other hand, this bug masked some other errors (related to handling ipv6 addresses); 3) The code for checking the locality of the ip address was different in the SST scripts for rsync and for mysqldump, with individual flaws. This code is now made common and moved to wsrep_sst_common; 4) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) in the wait_for_listen() and check_pid_and_port() functions did not process ipv6 addresses correctly in all cases (not for all branches); 5) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) in the wait_for_listen() and check_pid_and_port() functions for some code branches could give a false positive result due to the textual match of prefixes in the port number and/or PID of the process; 6) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) was supported through different utilities in SST scripts for mariabackup and for rsync, and with various minor flaws in the code. Now the code is still different in these scripts, but it supports a common set of utilities (lsof, ss, sockstat) and is synchronized across patterns that used to check the output of these utilities; 7) In SST via mariabackup, the signal about readiness to receive data is sometimes sent too early - immediately after listen(), and not after accept() (which are called by socat or netcat utility). 8) Checking availability of the some options of some utilities was done using the grep pattern, which easily gives false positives; 9) Common name (CN) for local addresses, if not explicitly specified, is now always replaced to "localhost" to avoid the need to generate many separate certificates for local addresses of one machine and not to depend on which the local address is currently used in test (ipv4 or ipv6, etc.); 10) In tests galera_sst_mariabackup_encrypt_with_key_server and galera_sst_rsync_encrypt_with_key_server the correct certificate is selected to avoid commonname (CN) mismatch problems; 11) Further refactoring to protect against spaces in file names. 12) Further general refactoring to eliminate bash-specific constructs or to improve code readability; 13) The code for setting options for the nc (netcat) utility was different in different scripts for SST - now it is made identical. 14) Fixed long-time broken encryption via xbcrypt in combination with mariabackup and added support for key-based encryption via openssl utility, which is now enabled by default for encrypt=1 mode (this default mode can be changed using a new configuration file option "encypt-format=openssl|xbcrypt", which can be placed in the [mysqld], [sst] or in the [xtrabackup] section) - this change will allow us to use and to test the encypt=1 encryption without installing non-standard third-party utilities.

MDEV-23580: WSREP_SST: [ERROR] rsync daemon port has been taken This commit contains a large set of further bug fixes and improvements to SST scripts for Galera, continuing the work that was started in MDEV-24962 to make SST scripts work smoothly in different network configurations (especially using ipv6) and with different environment settings: 1) The ipv6 addresses were incorrectly handled in the SST script for rsync (incorrect address substitution for establishing a connection, incorrect address substitution for bind, and so on); 2) Checking the locality of the ip-address in SST scripts did not support ipv6 addresses (such as "[::1]"), which were falsely identified as non-local ip, which further did not allow running two SSTs on different local addresses on the same machine. On the other hand, this bug masked some other errors (related to handling ipv6 addresses); 3) The code for checking the locality of the ip address was different in the SST scripts for rsync and for mysqldump, with individual flaws. This code is now made common and moved to wsrep_sst_common; 4) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) in the wait_for_listen() and check_pid_and_port() functions did not process ipv6 addresses correctly in all cases (not for all branches); 5) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) in the wait_for_listen() and check_pid_and_port() functions for some code branches could give a false positive result due to the textual match of prefixes in the port number and/or PID of the process; 6) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) was supported through different utilities in SST scripts for mariabackup and for rsync, and with various minor flaws in the code. Now the code is still different in these scripts, but it supports a common set of utilities (lsof, ss, sockstat) and is synchronized across patterns that used to check the output of these utilities; 7) In SST via mariabackup, the signal about readiness to receive data is sometimes sent too early - immediately after listen(), and not after accept() (which are called by socat or netcat utility). 8) Checking availability of the some options of some utilities was done using the grep pattern, which easily gives false positives; 9) Common name (CN) for local addresses, if not explicitly specified, is now always replaced to "localhost" to avoid the need to generate many separate certificates for local addresses of one machine and not to depend on which the local address is currently used in test (ipv4 or ipv6, etc.); 10) In tests galera_sst_mariabackup_encrypt_with_key_server and galera_sst_rsync_encrypt_with_key_server the correct certificate is selected to avoid commonname (CN) mismatch problems; 11) Further refactoring to protect against spaces in file names. 12) Further general refactoring to eliminate bash-specific constructs or to improve code readability; 13) The code for setting options for the nc (netcat) utility was different in different scripts for SST - now it is made identical. 14) Fixed long-time broken encryption via xbcrypt in combination with mariabackup and added support for key-based encryption via openssl utility, which is now enabled by default for encrypt=1 mode (this default mode can be changed using a new configuration file option "encypt-format=openssl|xbcrypt", which can be placed in the [mysqld], [sst] or in the [xtrabackup] section) - this change will allow us to use and to test the encypt=1 encryption without installing non-standard third-party utilities.

MDEV-27524: Incorrect binlogs after Galera SST using rsync and mariabackup This commit adds correct handling of binlogs for SST using rsync or mariabackup. Before this fix, binlogs were handled incorrectly - - only one (last) binary log file was transferred during SST, which then led to various failures (for example, when trying to list all events from the binary log). These bugs were long masked by flaws in the primitive binlogs handling code in the SST scripts, which causing binary logs files to be erased after transfer or not added to the binlog index on the joiner node. Now the correct transfer of all binary logs (not just the last of the binary log files) has been implemented both for the rsync (at the script level) and for the mariabackup (at the level of the main utility code). This commit also adds a new sst_max_binlogs=<n> parameter, which can be located in the [sst] section or in the [xtrabackup] section (historically, supported for mariabackup only, not for rsync), or in one of the server sections. This parameter specifies the number of binary log files to be sent to the joiner node during SST. This option is added for compatibility with old SST scripting behavior, which can be emulated by setting the sst_max_binlogs=1 (although in general this can cause problems for the reasons described above). In addition, setting the sst_max_binlogs=0 can be used to suppress the transmission of binary logs to the joiner nodes during SST (although sometimes a single file with the current binary log can still be transmitted to the joiner, even with sst_max_binlogs=0, because this sometimes necessary in modes that involve the use of GTIDs with Galera). Also, this commit ensures correct handling of paths to various innodb files and directories in the SST scripts, and fixes some problems with this that existed in mariabackup utility (which were associated with incorrect handling of the innodb_data_dir parameter in some scenarios). In addition, this commit contains the following enhancements: 1) Added tests for mtr, which check the correct work with binlogs after SST (using rsync and mariabackup); 2) Added correct handling of slashes at the end of all paths that the SST script receives as parameters; 3) Improved parsing code for --mysqld-args parameters. Now it correctly processes the sequence "--" after the name of the one-letter option; 4) Checking the secret signature during joiner authentication is made independent of presence of bash (as a unix shell) in the system and diff utility no longer needed to check certificates compliance; 5) All directories that are necessary for the correct placement of various logs are automatically created by SST scripts in advance (before running mariabackup on the joiner node); 6) Removal of old binary logs on joiner is done using the binlog index (if it exists) (not only by fixed pattern that based on the current binlog name, as before); 7) Paths for placing binary logs are correctly processed if they are set as relative paths (to the datadir); 8) SST scripts are made even more resistant to spaces in filenames (now for binlogs); 9) In case of failure, SST scripts now always end with an exit code other than zero; 10) SST script for rsync now correctly create a tar file with the binlogs, even if the paths to them (in the binlog index file) are specified as a mix of absolute and relative paths, and even if they do not match with the datadir path specified in the current configuration settings.

MDEV-27524: Incorrect binlogs after Galera SST using rsync and mariabackup This commit adds correct handling of binlogs for SST using rsync or mariabackup. Before this fix, binlogs were handled incorrectly - - only one (last) binary log file was transferred during SST, which then led to various failures (for example, when trying to list all events from the binary log). These bugs were long masked by flaws in the primitive binlogs handling code in the SST scripts, which causing binary logs files to be erased after transfer or not added to the binlog index on the joiner node. Now the correct transfer of all binary logs (not just the last of the binary log files) has been implemented both for the rsync (at the script level) and for the mariabackup (at the level of the main utility code). This commit also adds a new sst_max_binlogs=<n> parameter, which can be located in the [sst] section or in the [xtrabackup] section (historically, supported for mariabackup only, not for rsync), or in one of the server sections. This parameter specifies the number of binary log files to be sent to the joiner node during SST. This option is added for compatibility with old SST scripting behavior, which can be emulated by setting the sst_max_binlogs=1 (although in general this can cause problems for the reasons described above). In addition, setting the sst_max_binlogs=0 can be used to suppress the transmission of binary logs to the joiner nodes during SST (although sometimes a single file with the current binary log can still be transmitted to the joiner, even with sst_max_binlogs=0, because this sometimes necessary in modes that involve the use of GTIDs with Galera). Also, this commit ensures correct handling of paths to various innodb files and directories in the SST scripts, and fixes some problems with this that existed in mariabackup utility (which were associated with incorrect handling of the innodb_data_dir parameter in some scenarios). In addition, this commit contains the following enhancements: 1) Added tests for mtr, which check the correct work with binlogs after SST (using rsync and mariabackup); 2) Added correct handling of slashes at the end of all paths that the SST script receives as parameters; 3) Improved parsing code for --mysqld-args parameters. Now it correctly processes the sequence "--" after the name of the one-letter option; 4) Checking the secret signature during joiner authentication is made independent of presence of bash (as a unix shell) in the system and diff utility no longer needed to check certificates compliance; 5) All directories that are necessary for the correct placement of various logs are automatically created by SST scripts in advance (before running mariabackup on the joiner node); 6) Removal of old binary logs on joiner is done using the binlog index (if it exists) (not only by fixed pattern that based on the current binlog name, as before); 7) Paths for placing binary logs are correctly processed if they are set as relative paths (to the datadir); 8) SST scripts are made even more resistant to spaces in filenames (now for binlogs); 9) In case of failure, SST scripts now always end with an exit code other than zero; 10) SST script for rsync now correctly create a tar file with the binlogs, even if the paths to them (in the binlog index file) are specified as a mix of absolute and relative paths, and even if they do not match with the datadir path specified in the current configuration settings.

MDEV-24962: Galera SST innobackupex-move ignores Environment settings After switching to the new mariabackup interface (instead of the outdated innobackupex interface, which is supported for compatibility), we need to explicitly pass a path to the datadir directory as a parameter, since in the new interface the value of this option is not automatically set in such a way that it always matches the SST/IST logic. This commit adds passing this option as an explicit parameter to mariabackup. This commit also removed unnecessary options that are not used and not supported by mariabackup. Also, numerous flaws in the common wsrep_sst_common script have been fixed: 1) There are many bash-specific constructs in the script that may not be supported by other interpreters, which can lead to the most unexpected errors during SST, because failures in the interpretation of bash-specific constructs lead to incorrect parsing of arguments; 2) There is parse_cnf() function which is often called by other scripts for the "mysqld" or "--mysqld" group, but it does not take into account the default group suffix, which leads to reading values only from the default group, which then leads to errors due to reading the default values instead of the values for a specific group; 3) Some options such as --user, --innodb-data-home-dir or --datadir are not removed from the --mysqld-args list, although they are processed inside scripts (and passing of these options funther may cause problems for mariabackup); 4) If an argument that the script understands is present in the --mysqld-args list twice, then this causes SST to fail, instead of reading the most recent value; 5) The "--host" parameter is technically still supported among the arguments of the SST scripts, but in reality scripts do not work with it as expected, especially if it has an IPv6 address; 6) If the port number is absent in the --address parameter value, but the port number is explicitly passed through the --port argument, then the scripts for mariabackup and xtrabackup-v2 fail; 7) If a new address interface is used (with the --address parameter), then automatic default port substitution is not performed, although it is supported for the legacy --host/--port interface. 8) If there are spaces in the parameter values after --mysqld_args, then their further transfer does not occur correctly, which causes mariabackup to fail during SST - the space splits the argument in such a way that it breaks the parsing of the following parameters; 9) If most of the parameters that are names or paths to the files or directories contain spaces, then SST scripts fail in an unpredictable way due to incorrect variable substitutions; 10) If the --log-bin option is passed among the arguments of myqlds (--mysqld-args) without a parameter, and the --binlog option is not specified, then the script cannot substitute the default name for binlog and cannot construct binlog name using the --log-basename argument (which is against server specifications); 11) Tail slashes are not removed from the directory names, which, upon further substitution, leads to the appearance of a double slash in the file paths; 12) The explicit --binlog parameter (which is now always transmitted from the server side) and the "hidden" --log-bin parameter in the list of arguments after --mysqld-args are perceived as two different parameters in different parts of the scripts, and if they are do not match for some reason, this will lead to failures during SST; Also, all new changes from the 10.6 branch have been migrated here, including the latest pull requests for authentication (only the part that concerns SST scripts). It also fixes dozens of other bugs in all SST scripts.

MDEV-23580: WSREP_SST: [ERROR] rsync daemon port has been taken This commit contains a large set of further bug fixes and improvements to SST scripts for Galera, continuing the work that was started in MDEV-24962 to make SST scripts work smoothly in different network configurations (especially using ipv6) and with different environment settings: 1) The ipv6 addresses were incorrectly handled in the SST script for rsync (incorrect address substitution for establishing a connection, incorrect address substitution for bind, and so on); 2) Checking the locality of the ip-address in SST scripts did not support ipv6 addresses (such as "[::1]"), which were falsely identified as non-local ip, which further did not allow running two SSTs on different local addresses on the same machine. On the other hand, this bug masked some other errors (related to handling ipv6 addresses); 3) The code for checking the locality of the ip address was different in the SST scripts for rsync and for mysqldump, with individual flaws. This code is now made common and moved to wsrep_sst_common; 4) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) in the wait_for_listen() and check_pid_and_port() functions did not process ipv6 addresses correctly in all cases (not for all branches); 5) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) in the wait_for_listen() and check_pid_and_port() functions for some code branches could give a false positive result due to the textual match of prefixes in the port number and/or PID of the process; 6) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) was supported through different utilities in SST scripts for mariabackup and for rsync, and with various minor flaws in the code. Now the code is still different in these scripts, but it supports a common set of utilities (lsof, ss, sockstat) and is synchronized across patterns that used to check the output of these utilities; 7) In SST via mariabackup, the signal about readiness to receive data is sometimes sent too early - immediately after listen(), and not after accept() (which are called by socat or netcat utility). 8) Checking availability of the some options of some utilities was done using the grep pattern, which easily gives false positives; 9) Common name (CN) for local addresses, if not explicitly specified, is now always replaced to "localhost" to avoid the need to generate many separate certificates for local addresses of one machine and not to depend on which the local address is currently used in test (ipv4 or ipv6, etc.); 10) In tests galera_sst_mariabackup_encrypt_with_key_server and galera_sst_rsync_encrypt_with_key_server the correct certificate is selected to avoid commonname (CN) mismatch problems; 11) Further refactoring to protect against spaces in file names. 12) Further general refactoring to eliminate bash-specific constructs or to improve code readability; 13) The code for setting options for the nc (netcat) utility was different in different scripts for SST - now it is made identical. 14) Fixed long-time broken encryption via xbcrypt in combination with mariabackup and added support for key-based encryption via openssl utility, which is now enabled by default for encrypt=1 mode (this default mode can be changed using a new configuration file option "encypt-format=openssl|xbcrypt", which can be placed in the [mysqld], [sst] or in the [xtrabackup] section) - this change will allow us to use and to test the encypt=1 encryption without installing non-standard third-party utilities.

# Compact backups are not supported by mariadb-backup
MDEV-24097: galera[_3nodes] suite tests in MTR sporadically fails This is the first part of the fixes for MDEV-24097. This commit contains the fixes for instability when testing Galera and when restarting nodes quickly: 1) Protection against a "stuck" old SST process during the execution of the new SST (after restarting the node) is now implemented for mariabackup / xtrabackup, which should help to avoid almost all conflicts due to the use of the same ports - both during testing with mtr, so and when restarting nodes quickly in a production environment. 2) Added more protection to scripts against unexpected return of the rc != 0 (in the commands for deleting temporary files, etc). 3) Added protection against unexpected crashes during binlog transfer (in SST scripts for rsync). 4) Spaces and some special characters in binlog filenames shouldn't be a problem now (at the script level). 5) Daemon process termination tracking has been made more robust against crashes due to unexpected termination of the previous SST process while new scripts are running. 6) Reading ssl encryption parameters has been moved from specific SST scripts to a common wsrep_sst_common.sh script, which allows unified error handling, unified diagnostics and simplifies script revisions in the future. 7) Improved diagnostics of errors related to the use of openssl. 8) Corrections have been made for xtrabackup-v2 (both in tests and in the script code) that restore the work of xtrabackup with updated versions of innodb. 9) Fixed some tests for galera_3nodes, although the complete solution for the problem of starting three nodes at the same time on fast machines will be done in a separate commit. No additional tests are required as this commit fixes problems with existing tests.

MDEV-27524: Incorrect binlogs after Galera SST using rsync and mariabackup This commit adds correct handling of binlogs for SST using rsync or mariabackup. Before this fix, binlogs were handled incorrectly - - only one (last) binary log file was transferred during SST, which then led to various failures (for example, when trying to list all events from the binary log). These bugs were long masked by flaws in the primitive binlogs handling code in the SST scripts, which causing binary logs files to be erased after transfer or not added to the binlog index on the joiner node. Now the correct transfer of all binary logs (not just the last of the binary log files) has been implemented both for the rsync (at the script level) and for the mariabackup (at the level of the main utility code). This commit also adds a new sst_max_binlogs=<n> parameter, which can be located in the [sst] section or in the [xtrabackup] section (historically, supported for mariabackup only, not for rsync), or in one of the server sections. This parameter specifies the number of binary log files to be sent to the joiner node during SST. This option is added for compatibility with old SST scripting behavior, which can be emulated by setting the sst_max_binlogs=1 (although in general this can cause problems for the reasons described above). In addition, setting the sst_max_binlogs=0 can be used to suppress the transmission of binary logs to the joiner nodes during SST (although sometimes a single file with the current binary log can still be transmitted to the joiner, even with sst_max_binlogs=0, because this sometimes necessary in modes that involve the use of GTIDs with Galera). Also, this commit ensures correct handling of paths to various innodb files and directories in the SST scripts, and fixes some problems with this that existed in mariabackup utility (which were associated with incorrect handling of the innodb_data_dir parameter in some scenarios). In addition, this commit contains the following enhancements: 1) Added tests for mtr, which check the correct work with binlogs after SST (using rsync and mariabackup); 2) Added correct handling of slashes at the end of all paths that the SST script receives as parameters; 3) Improved parsing code for --mysqld-args parameters. Now it correctly processes the sequence "--" after the name of the one-letter option; 4) Checking the secret signature during joiner authentication is made independent of presence of bash (as a unix shell) in the system and diff utility no longer needed to check certificates compliance; 5) All directories that are necessary for the correct placement of various logs are automatically created by SST scripts in advance (before running mariabackup on the joiner node); 6) Removal of old binary logs on joiner is done using the binlog index (if it exists) (not only by fixed pattern that based on the current binlog name, as before); 7) Paths for placing binary logs are correctly processed if they are set as relative paths (to the datadir); 8) SST scripts are made even more resistant to spaces in filenames (now for binlogs); 9) In case of failure, SST scripts now always end with an exit code other than zero; 10) SST script for rsync now correctly create a tar file with the binlogs, even if the paths to them (in the binlog index file) are specified as a mix of absolute and relative paths, and even if they do not match with the datadir path specified in the current configuration settings.

MDEV-23580: WSREP_SST: [ERROR] rsync daemon port has been taken This commit contains a large set of further bug fixes and improvements to SST scripts for Galera, continuing the work that was started in MDEV-24962 to make SST scripts work smoothly in different network configurations (especially using ipv6) and with different environment settings: 1) The ipv6 addresses were incorrectly handled in the SST script for rsync (incorrect address substitution for establishing a connection, incorrect address substitution for bind, and so on); 2) Checking the locality of the ip-address in SST scripts did not support ipv6 addresses (such as "[::1]"), which were falsely identified as non-local ip, which further did not allow running two SSTs on different local addresses on the same machine. On the other hand, this bug masked some other errors (related to handling ipv6 addresses); 3) The code for checking the locality of the ip address was different in the SST scripts for rsync and for mysqldump, with individual flaws. This code is now made common and moved to wsrep_sst_common; 4) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) in the wait_for_listen() and check_pid_and_port() functions did not process ipv6 addresses correctly in all cases (not for all branches); 5) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) in the wait_for_listen() and check_pid_and_port() functions for some code branches could give a false positive result due to the textual match of prefixes in the port number and/or PID of the process; 6) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) was supported through different utilities in SST scripts for mariabackup and for rsync, and with various minor flaws in the code. Now the code is still different in these scripts, but it supports a common set of utilities (lsof, ss, sockstat) and is synchronized across patterns that used to check the output of these utilities; 7) In SST via mariabackup, the signal about readiness to receive data is sometimes sent too early - immediately after listen(), and not after accept() (which are called by socat or netcat utility). 8) Checking availability of the some options of some utilities was done using the grep pattern, which easily gives false positives; 9) Common name (CN) for local addresses, if not explicitly specified, is now always replaced to "localhost" to avoid the need to generate many separate certificates for local addresses of one machine and not to depend on which the local address is currently used in test (ipv4 or ipv6, etc.); 10) In tests galera_sst_mariabackup_encrypt_with_key_server and galera_sst_rsync_encrypt_with_key_server the correct certificate is selected to avoid commonname (CN) mismatch problems; 11) Further refactoring to protect against spaces in file names. 12) Further general refactoring to eliminate bash-specific constructs or to improve code readability; 13) The code for setting options for the nc (netcat) utility was different in different scripts for SST - now it is made identical. 14) Fixed long-time broken encryption via xbcrypt in combination with mariabackup and added support for key-based encryption via openssl utility, which is now enabled by default for encrypt=1 mode (this default mode can be changed using a new configuration file option "encypt-format=openssl|xbcrypt", which can be placed in the [mysqld], [sst] or in the [xtrabackup] section) - this change will allow us to use and to test the encypt=1 encryption without installing non-standard third-party utilities.

MDEV-25818: RSYNC SST failed due to busy port This commit reduces the likelihood of getting a busy port on quick restarts with rsync SST (problem MDEV-25818) and fixes a number of other flaws in SST scripts, adds new functionality, and also synchronizes the xtrabackup-v2 script with the mariabackup script (the latter applies only to the 10.2 branch): 1) SST via rsync: rsync and stunnel does not always get the right time to complete by correctly handling SIGTERM. These utilities are now given more time to complete normally (via normal SIGTERM processing) before we move on to using "kill -9"; 2) SST via rsync: attempts to terminate an rsync or stunnel process (via "kill" utility) are only made if it did not terminated on its own; 3) SST via rsync: if a combination of stunnel and rsync is used, then we need to wait for both utilities to finish or stop, not just one of them; 4) The config file and pid file for stunnel are now deleted after successful completion of SST on the donor node; 5) The configs and pid files from rsync and stunnel should not be deleted unless these utilities succeed (or are sucessfully terminated) on the joiner node; 6) The configs and pid files now excluded from transfer via rsync; 7) Spaces in paths are now valid for config files as well (when used with SST via rsync or mariabackup / xtrabackup[-v2]); 8) SST via mariabackup: added preliminary verification of keys and certificates that are used when establishing a connection using SSL (to avoid long timeouts and improve diagnostics) - by analogy with how it is done for the xtrabackup-v2 (plus check for CA file), while that check is skipped if the user does not have openssl installed (or does not have diff utility); 9) Added backup-threads=<n> configuration option which adds "--parallel=<n>" for mariabackup / xtrabackup at backup and move-back stages; 10) Added encrypt-threads and encrypt-chunk-size configuration options for xbcrypt management (when xbcrypt is used); 11) Small optimization: checking the socat version and adding a file with parameters for 2048-bit Diffie-Hellman (if necessary) is done only if the user has not specified "dhparam=" in the "sockopt" option value; 12) SST via rsync now supports "backup-threads" configuration option (in server-related sections or in the "[sst]"); 13) Determining the number of available processors is now supported for FreeBSD + mariabackup/xtrabackup: before that we might have problems with "--compact" (rebuild indexes) or qpress on FreeBSD; 14) The check_pid() function should not raise an error state in the rare cases when the pid file was created, but it is empty, or if it is deleted right during the check, or when zero is read from the pid file; 15) Iproved templates that are used to check if a requested socket is "listening" when using the ss utility; 16) Shortened some other templates for socket state utilities; 17) Temporary files created by mariabackup / xtrabackup are moved to a separate subdirectory inside tmpdir (so they don't get mixed with other temporary files, which can make debugging more difficult); 18) 10.2 only: the script for SST via xtrabackup-v2 has been brought in full compliance with all the bugfixes made for mariabackup (as it previously contained many flaws compared to the updated script for mariabackup).

MDEV-24962: Galera SST innobackupex-move ignores Environment settings After switching to the new mariabackup interface (instead of the outdated innobackupex interface, which is supported for compatibility), we need to explicitly pass a path to the datadir directory as a parameter, since in the new interface the value of this option is not automatically set in such a way that it always matches the SST/IST logic. This commit adds passing this option as an explicit parameter to mariabackup. This commit also removed unnecessary options that are not used and not supported by mariabackup. Also, numerous flaws in the common wsrep_sst_common script have been fixed: 1) There are many bash-specific constructs in the script that may not be supported by other interpreters, which can lead to the most unexpected errors during SST, because failures in the interpretation of bash-specific constructs lead to incorrect parsing of arguments; 2) There is parse_cnf() function which is often called by other scripts for the "mysqld" or "--mysqld" group, but it does not take into account the default group suffix, which leads to reading values only from the default group, which then leads to errors due to reading the default values instead of the values for a specific group; 3) Some options such as --user, --innodb-data-home-dir or --datadir are not removed from the --mysqld-args list, although they are processed inside scripts (and passing of these options funther may cause problems for mariabackup); 4) If an argument that the script understands is present in the --mysqld-args list twice, then this causes SST to fail, instead of reading the most recent value; 5) The "--host" parameter is technically still supported among the arguments of the SST scripts, but in reality scripts do not work with it as expected, especially if it has an IPv6 address; 6) If the port number is absent in the --address parameter value, but the port number is explicitly passed through the --port argument, then the scripts for mariabackup and xtrabackup-v2 fail; 7) If a new address interface is used (with the --address parameter), then automatic default port substitution is not performed, although it is supported for the legacy --host/--port interface. 8) If there are spaces in the parameter values after --mysqld_args, then their further transfer does not occur correctly, which causes mariabackup to fail during SST - the space splits the argument in such a way that it breaks the parsing of the following parameters; 9) If most of the parameters that are names or paths to the files or directories contain spaces, then SST scripts fail in an unpredictable way due to incorrect variable substitutions; 10) If the --log-bin option is passed among the arguments of myqlds (--mysqld-args) without a parameter, and the --binlog option is not specified, then the script cannot substitute the default name for binlog and cannot construct binlog name using the --log-basename argument (which is against server specifications); 11) Tail slashes are not removed from the directory names, which, upon further substitution, leads to the appearance of a double slash in the file paths; 12) The explicit --binlog parameter (which is now always transmitted from the server side) and the "hidden" --log-bin parameter in the list of arguments after --mysqld-args are perceived as two different parameters in different parts of the scripts, and if they are do not match for some reason, this will lead to failures during SST; Also, all new changes from the 10.6 branch have been migrated here, including the latest pull requests for authentication (only the part that concerns SST scripts). It also fixes dozens of other bugs in all SST scripts.

MDEV-24962: Galera SST innobackupex-move ignores Environment settings After switching to the new mariabackup interface (instead of the outdated innobackupex interface, which is supported for compatibility), we need to explicitly pass a path to the datadir directory as a parameter, since in the new interface the value of this option is not automatically set in such a way that it always matches the SST/IST logic. This commit adds passing this option as an explicit parameter to mariabackup. This commit also removed unnecessary options that are not used and not supported by mariabackup. Also, numerous flaws in the common wsrep_sst_common script have been fixed: 1) There are many bash-specific constructs in the script that may not be supported by other interpreters, which can lead to the most unexpected errors during SST, because failures in the interpretation of bash-specific constructs lead to incorrect parsing of arguments; 2) There is parse_cnf() function which is often called by other scripts for the "mysqld" or "--mysqld" group, but it does not take into account the default group suffix, which leads to reading values only from the default group, which then leads to errors due to reading the default values instead of the values for a specific group; 3) Some options such as --user, --innodb-data-home-dir or --datadir are not removed from the --mysqld-args list, although they are processed inside scripts (and passing of these options funther may cause problems for mariabackup); 4) If an argument that the script understands is present in the --mysqld-args list twice, then this causes SST to fail, instead of reading the most recent value; 5) The "--host" parameter is technically still supported among the arguments of the SST scripts, but in reality scripts do not work with it as expected, especially if it has an IPv6 address; 6) If the port number is absent in the --address parameter value, but the port number is explicitly passed through the --port argument, then the scripts for mariabackup and xtrabackup-v2 fail; 7) If a new address interface is used (with the --address parameter), then automatic default port substitution is not performed, although it is supported for the legacy --host/--port interface. 8) If there are spaces in the parameter values after --mysqld_args, then their further transfer does not occur correctly, which causes mariabackup to fail during SST - the space splits the argument in such a way that it breaks the parsing of the following parameters; 9) If most of the parameters that are names or paths to the files or directories contain spaces, then SST scripts fail in an unpredictable way due to incorrect variable substitutions; 10) If the --log-bin option is passed among the arguments of myqlds (--mysqld-args) without a parameter, and the --binlog option is not specified, then the script cannot substitute the default name for binlog and cannot construct binlog name using the --log-basename argument (which is against server specifications); 11) Tail slashes are not removed from the directory names, which, upon further substitution, leads to the appearance of a double slash in the file paths; 12) The explicit --binlog parameter (which is now always transmitted from the server side) and the "hidden" --log-bin parameter in the list of arguments after --mysqld-args are perceived as two different parameters in different parts of the scripts, and if they are do not match for some reason, this will lead to failures during SST; Also, all new changes from the 10.6 branch have been migrated here, including the latest pull requests for authentication (only the part that concerns SST scripts). It also fixes dozens of other bugs in all SST scripts.

MDEV-25818: RSYNC SST failed due to busy port This commit reduces the likelihood of getting a busy port on quick restarts with rsync SST (problem MDEV-25818) and fixes a number of other flaws in SST scripts, adds new functionality, and also synchronizes the xtrabackup-v2 script with the mariabackup script (the latter applies only to the 10.2 branch): 1) SST via rsync: rsync and stunnel does not always get the right time to complete by correctly handling SIGTERM. These utilities are now given more time to complete normally (via normal SIGTERM processing) before we move on to using "kill -9"; 2) SST via rsync: attempts to terminate an rsync or stunnel process (via "kill" utility) are only made if it did not terminated on its own; 3) SST via rsync: if a combination of stunnel and rsync is used, then we need to wait for both utilities to finish or stop, not just one of them; 4) The config file and pid file for stunnel are now deleted after successful completion of SST on the donor node; 5) The configs and pid files from rsync and stunnel should not be deleted unless these utilities succeed (or are sucessfully terminated) on the joiner node; 6) The configs and pid files now excluded from transfer via rsync; 7) Spaces in paths are now valid for config files as well (when used with SST via rsync or mariabackup / xtrabackup[-v2]); 8) SST via mariabackup: added preliminary verification of keys and certificates that are used when establishing a connection using SSL (to avoid long timeouts and improve diagnostics) - by analogy with how it is done for the xtrabackup-v2 (plus check for CA file), while that check is skipped if the user does not have openssl installed (or does not have diff utility); 9) Added backup-threads=<n> configuration option which adds "--parallel=<n>" for mariabackup / xtrabackup at backup and move-back stages; 10) Added encrypt-threads and encrypt-chunk-size configuration options for xbcrypt management (when xbcrypt is used); 11) Small optimization: checking the socat version and adding a file with parameters for 2048-bit Diffie-Hellman (if necessary) is done only if the user has not specified "dhparam=" in the "sockopt" option value; 12) SST via rsync now supports "backup-threads" configuration option (in server-related sections or in the "[sst]"); 13) Determining the number of available processors is now supported for FreeBSD + mariabackup/xtrabackup: before that we might have problems with "--compact" (rebuild indexes) or qpress on FreeBSD; 14) The check_pid() function should not raise an error state in the rare cases when the pid file was created, but it is empty, or if it is deleted right during the check, or when zero is read from the pid file; 15) Iproved templates that are used to check if a requested socket is "listening" when using the ss utility; 16) Shortened some other templates for socket state utilities; 17) Temporary files created by mariabackup / xtrabackup are moved to a separate subdirectory inside tmpdir (so they don't get mixed with other temporary files, which can make debugging more difficult); 18) 10.2 only: the script for SST via xtrabackup-v2 has been brought in full compliance with all the bugfixes made for mariabackup (as it previously contained many flaws compared to the updated script for mariabackup).

MDEV-23580: WSREP_SST: [ERROR] rsync daemon port has been taken This commit contains a large set of further bug fixes and improvements to SST scripts for Galera, continuing the work that was started in MDEV-24962 to make SST scripts work smoothly in different network configurations (especially using ipv6) and with different environment settings: 1) The ipv6 addresses were incorrectly handled in the SST script for rsync (incorrect address substitution for establishing a connection, incorrect address substitution for bind, and so on); 2) Checking the locality of the ip-address in SST scripts did not support ipv6 addresses (such as "[::1]"), which were falsely identified as non-local ip, which further did not allow running two SSTs on different local addresses on the same machine. On the other hand, this bug masked some other errors (related to handling ipv6 addresses); 3) The code for checking the locality of the ip address was different in the SST scripts for rsync and for mysqldump, with individual flaws. This code is now made common and moved to wsrep_sst_common; 4) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) in the wait_for_listen() and check_pid_and_port() functions did not process ipv6 addresses correctly in all cases (not for all branches); 5) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) in the wait_for_listen() and check_pid_and_port() functions for some code branches could give a false positive result due to the textual match of prefixes in the port number and/or PID of the process; 6) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) was supported through different utilities in SST scripts for mariabackup and for rsync, and with various minor flaws in the code. Now the code is still different in these scripts, but it supports a common set of utilities (lsof, ss, sockstat) and is synchronized across patterns that used to check the output of these utilities; 7) In SST via mariabackup, the signal about readiness to receive data is sometimes sent too early - immediately after listen(), and not after accept() (which are called by socat or netcat utility). 8) Checking availability of the some options of some utilities was done using the grep pattern, which easily gives false positives; 9) Common name (CN) for local addresses, if not explicitly specified, is now always replaced to "localhost" to avoid the need to generate many separate certificates for local addresses of one machine and not to depend on which the local address is currently used in test (ipv4 or ipv6, etc.); 10) In tests galera_sst_mariabackup_encrypt_with_key_server and galera_sst_rsync_encrypt_with_key_server the correct certificate is selected to avoid commonname (CN) mismatch problems; 11) Further refactoring to protect against spaces in file names. 12) Further general refactoring to eliminate bash-specific constructs or to improve code readability; 13) The code for setting options for the nc (netcat) utility was different in different scripts for SST - now it is made identical. 14) Fixed long-time broken encryption via xbcrypt in combination with mariabackup and added support for key-based encryption via openssl utility, which is now enabled by default for encrypt=1 mode (this default mode can be changed using a new configuration file option "encypt-format=openssl|xbcrypt", which can be placed in the [mysqld], [sst] or in the [xtrabackup] section) - this change will allow us to use and to test the encypt=1 encryption without installing non-standard third-party utilities.

On the other hand, this bug masked some other errors (related to handling ipv6 addresses); 3) The code for checking the locality of the ip address was different in the SST scripts for rsync and for mysqldump, with individual flaws. This code is now made common and moved to wsrep_sst_common; 4) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) in the wait_for_listen() and check_pid_and_port() functions did not process ipv6 addresses correctly in all cases (not for all branches); 5) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) in the wait_for_listen() and check_pid_and_port() functions for some code branches could give a false positive result due to the textual match of prefixes in the port number and/or PID of the process; 6) Waiting for the start of the transport channel (socat, nc, rsync, stunnel) was supported through different utilities in SST scripts for mariabackup and for rsync, and with various minor flaws in the code. Now the code is still different in these scripts, but it supports a common set of utilities (lsof, ss, sockstat) and is synchronized across patterns that used to check the output of these utilities; 7) In SST via mariabackup, the signal about readiness to receive data is sometimes sent too early - immediately after listen(), and not after accept() (which are called by socat or netcat utility). 8) Checking availability of the some options of some utilities was done using the grep pattern, which easily gives false positives; 9) Common name (CN) for local addresses, if not explicitly specified, is now always replaced to "localhost" to avoid the need to generate many separate certificates for local addresses of one machine and not to depend on which the local address is currently used in test (ipv4 or ipv6, etc.); 10) In tests galera_sst_mariabackup_encrypt_with_key_server and galera_sst_rsync_encrypt_with_key_server the correct certificate is selected to avoid commonname (CN) mismatch problems; 11) Further refactoring to protect against spaces in file names. 12) Further general refactoring to eliminate bash-specific constructs or to improve code readability; 13) The code for setting options for the nc (netcat) utility was different in different scripts for SST - now it is made identical. 14) Fixed long-time broken encryption via xbcrypt in combination with mariabackup and added support for key-based encryption via openssl utility, which is now enabled by default for encrypt=1 mode (this default mode can be changed using a new configuration file option "encypt-format=openssl|xbcrypt", which can be placed in the [mysqld], [sst] or in the [xtrabackup] section) - this change will allow us to use and to test the encypt=1 encryption without installing non-standard third-party utilities.
