Write only one encryption key to the checkpoint page. Use 4 bytes of nonce. Encrypt more of each redo log block, only skipping the 4-byte field LOG_BLOCK_HDR_NO which the initialization vector is derived from. Issue notes, not warning messages for rewriting the redo log files. recv_recovery_from_checkpoint_finish(): Do not generate any redo log, because we must avoid that before rewriting the redo log files, or otherwise a crash during a redo log rewrite (removing or adding encryption) may end up making the database unrecoverable. Instead, do these tasks in innobase_start_or_create_for_mysql(). Issue a firm "Missing MLOG_CHECKPOINT" error message. Remove some unreachable code and duplicated error messages for log corruption. LOG_HEADER_FORMAT_ENCRYPTED: A flag for identifying an encrypted redo log format. log_group_t::is_encrypted(), log_t::is_encrypted(): Determine if the redo log is in encrypted format. recv_find_max_checkpoint(): Interpret LOG_HEADER_FORMAT_ENCRYPTED. srv_prepare_to_delete_redo_log_files(): Display NOTE messages about adding or removing encryption. Do not issue warnings for redo log resizing any more. innobase_start_or_create_for_mysql(): Rebuild the redo logs also when the encryption changes. innodb_log_checksums_func_update(): Always use the CRC-32C checksum if innodb_encrypt_log. If needed, issue a warning that innodb_encrypt_log implies innodb_log_checksums. log_group_write_buf(): Compute the checksum on the encrypted block contents, so that transmission errors or incomplete blocks can be detected without decrypting. Rewrite most of the redo log encryption code. Only remember one encryption key at a time (but remember up to 5 when upgrading from the MariaDB 10.1 format.) |

MariaDB: drop-in replacement for MySQL
MariaDB is designed as a drop-in replacement of MySQL(R) with more features, new storage engines, fewer bugs, and better performance.
MariaDB is brought to you by the MariaDB Foundation. Please read the CREDITS file for details about the MariaDB Foundation, and who is developing MariaDB.
MariaDB is developed by many of the original developers of MySQL who now work for the MariadB Foundation and the MariaDB Corporation, and by many people in the community.
MySQL, which is the base of MariaDB, is a product and trademark of Oracle Corporation, Inc. For a list of developers and other contributors, see the Credits appendix. You can also run 'SHOW authors' to get a list of active contributors.
A description of the MariaDB project and a manual can be found at: http://mariadb.org/ https://mariadb.com/kb/en/ https://mariadb.com/kb/en/mariadb-vs-mysql-features/ https://mariadb.com/kb/en/mariadb-versus-mysql-features/ https://mariadb.com/kb/en/mariadb-versus-mysql-compatibility/
As MariaDB is a full replacement of MySQL, the MySQL manual at http://dev.mysql.com/doc is generally applicable.
Help:
More help is available from the Maria Discuss mailing list https://launchpad.net/~maria-discuss and the #maria IRC channel on Freenode.
