Abort startup, if SSL setup fails.
Also, for the server always check that certificate matches private key
(even if ssl_cert is not set, OpenSSL will try to use default one)
1) Removed symlinks that are not very well supported in tar under Windows.
2) Added comment + changed code formatting in viosslfactories.c
3) Fixed a small bug in the yassl code.
4) Fixed a typo in the script code.
1. Galera SST scripts should use ssl_capath (not ssl_ca) for CA
directory. The current implementation tries to automatically
detect the path using the trailing slash in the ssl_ca variable
value, but this approach is not compatible with the server
configuration. Now, by analogy with the server, SST scripts
also use a separate ssl_capath variable. In addition, a similar
tcapath variable has been added for the old-style configuration
(in the "sst" section).
2. Openssl utility detection made more reliable.
3. Removed extra spaces in automatically generated command lines -
to simplify debugging of the SST scripts.
4. In general, the code for detecting the presence or absence of
auxiliary utilities has been improved - it is made more reliable
in some configurations (and for shells other than bash).

Due to restricted size of the threadpool, execution of client queries can
be delayed (queued) for a while. This delay was interpreted as client
inactivity, and connection is closed, if client idle time + queue time
exceeds wait_timeout.
But users did not expect queue time to be included into wait_timeout.
This patch changes the behavior. We don't close connection anymore,
if there is some unread data present on connection,
even if wait_timeout is exceeded. Unread data means that client
was not idle, it sent a query, which we did not have time to process yet.
Fix is not to use blocking socket IO during SSL handshake.
With non-blocking socket IO, threadpool is able to utilize the wait
notification callbacks, that vio_io_wait() is calling whenever
socket would block.
Handle string length as size_t, consistently (almost always:))
Change function prototypes to accept size_t, where in the past
ulong or uint were used. change local/member variables to size_t
when appropriate.
This fix excludes rocksdb, spider,spider, sphinx and connect for now.
first, and we do not not care whether client has received all data.
This is a TCP optimization to avoid TIME_WAIT in TCP connection teardown.
This patch would abort connection on timeout, which usually happens when
client reads a large result set, at slower pace then the server can
write.
The patch also cleans up socket timeout handling, so that Windows
is consistent with another platforms (using nonblocking socket IO
+ waiting in poll/select on single socket, rather than setsockopt).
This makes identifying timeouts easier.
Also removed the superficial shutdown() before closesocket() in a few
places where it was used, because it was never needed , and
reportedly breaks SO_LINGER on Windows.
- Fix win64 pointer truncation warnings
(usually coming from misusing 0x%lx and long cast in DBUG)
- Also fix printf-format warnings
Make the above mentioned warnings fatal.
- fix pthread_join on Windows to set return value.
- the probably ultimate fix for dependencies on VS
- remove some GET_TARGET_PROPERTY(LOCATION ...), they are deprecated in
cmake 3.9
- simplify signing targets on Windows.
- remove INSTALL_DEBUG_TARGET, we do not mix binaries from different builds
in the same package
accept proxy protocol header from client connections.
The new server variable 'proxy_protocol_networks' contains list
of networks from which proxy header is accepted.
post-review fixes:
* move all ssl implementation related ifdefs/defines to one file
(ssl_compat.h)
* work around OpenSSL-1.1 desire to malloc every EVP context by
run-time checking that context allocated on the stack is big enough
(openssl.c)
* use newer version of the AWS SDK for OpenSSL 1.1
* use get_dh2048() function as generated by openssl 1.1
(viosslfactories.c)
Initial support
tested against OpenSSL 1.0.1, 1.0.2, 1.1.0, Yassl and LibreSSL
not working on Windows with native SChannel support, due to wrong cipher
mapping: Latter one requires push of CONC-241 fixes.
Please note that OpenSSL 0.9.8 and OpenSSL 1.1.0 will not work: Even if
the build succeeds, test cases will fail with various errors, especially
when using different tls libraries or versions for client and server.
- Fixed typos
- Added --core-on-failure to mysql-test-run
- More DBUG_PRINT in viosocket.c
- Don't forget CLIENT_REMEMBER_OPTIONS for compressed slave protocol
- Removed not used stage variables
FOUND
Description:- Failure during the validation of CA
certificate path which is provided as an option for 'ssl-ca'
returns two different errors for YaSSL and OPENSSL.
Analysis:- 'ssl-ca', option used for specifying the ssl ca
certificate path. Failing to validate this certificate with
OPENSSL returns an error, "ERROR 2026 (HY000): SSL
connection error: SSL_CTX_set_default_verify_paths failed".
While YASSL returns "ERROR 2026 (HY000): SSL connection
error: ASN: bad other signature confirmation". Error
returned by the OPENSSL is correct since
"SSL_CTX_load_verify_locations()" returns 0 (in case of
OPENSSL) for the failure and sets error as
"SSL_INITERR_BAD_PATHS". In case of YASSL,
"SSL_CTX_load_verify_locations()" returns an error number
which is less than or equal to 0 in case of error. Error
numbers for YASSL is mentioned in the file,
'extra/yassl/include/openssl/ssl.h'(line no : 292). Also
'ssl-ca' does not accept tilde home directory path
substitution.
Fix:- The condition which checks for the error in the
"SSL_CTX_load_verify_locations()" is changed in order to
accommodate YASSL as well. A logic is written in
"mysql_ssl_set()" in order accept the tilde home directory
path substitution for all ssl options.
