- 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.
Description: The newest RHEL/CentOS/SL 6.6 openssl package
(1.0.1e-30.el6_6.9; published around 6/4/2015) contains a fix for
LogJam. RedHat's fix for this was to limit the use
of any SSL DH key sizes to a minimum of 768 bits. This breaks any
DHE SSL ciphers for MySQL clients as soon as you install the
openssl update, since in vio/viosslfactories.c, the default
DHPARAM is a 512 bit one. This cannot be changed in
configuration/runtime; and needs a recompile. Because of this the
client connection with --ssl-cipher=DHE-RSA-AES256-SHA is not
able to connect the server.
Analysis: Openssl has changed Diffie-Hellman key from the 512 to
1024 due to some reasons(please see the details at
http://openssl.org/news/secadv_20150611.txt) Because of this the client
with DHE cipher is failing to connect the server. This change took
place from the openssl-1.0.1n onwards.
Fix: Similar bug fix is already pushed to mysql-5.7 under bug#18367167.
Hence we backported the same fix to mysql-5.5 and mysql-5.6.
in when using vio->read_timeout (and write_timeout) to set
timeouts of a new vio, as in:
vio_timeout(vio, 0, old_vio.read_timeout)
vio_timeout(vio, 0, old_vio.write_timeout)
remember that timeouts are stored in ms, but vio_timeout()'s
argument is in seconds.
On EOF vio_read returns 0, it's not an error so the errno
is not reset. If the previous error was EINTR the client
will loop forever. See also man recv.
Description:
Can't build mysql-5.5 latest source with openssl 0.9.8e.
Analysis:
Older OpenSSL versions(prior to openssl 1.0) doesn't have 'SSL_OP_NO_COMPRESSION' defined.
Hence the build is failing with SSL_OP_NO_COMPRESSION undeclared.
Fix:
Added a conditonal compilation for 'SSL_OP_NO_COMPRESSION'.
i.e if 'SSL_OP_NO_COMPRESSION' is defined then have the SSL_set_options call for OpenSSL 1.0 versions.
Have sk_SSL_COMP_zero() call for OpenSSL 0.9.8 version
* adjust viossl.c to take account the new code
(SSL_get_error is used now, cannot simply remap it)
* remove unnecessary version check
* update the test to 10.0
followup:
* explicitly disable SSLv2 and SSLv3, keep other protocols enabled
* fix a compiler warning
* rename the test and combinations to avoid confusion
vio/viossl.c:
fix a compiler warning
change SSL methods to be SSLv23 (according to openssl manpage:
"A TLS/SSL connection established with these methods may understand
the SSLv2, SSLv3, TLSv1, TLSv1.1 and TLSv1.2 protocols") from
TLSv1 methods, that go back to the initial SSL implementation
in MySQL in 2001.
OpenSSL default ciphers are different if TLSv1.2 is enabled,
so tests need to take this into account.

Bug#18187290 ISSUE WITH BUILDING MYSQL USING CMAKE 2.8.12
We want to upgrade to VS2013 on Windows.
In order to do this, we need to upgrade to cmake 2.8.12
This has introduced some incompatibilities for .pdb files,
and "make install" no longer works.
To reproduce:
cmake --build . --target package --config debug
The fix:
Rather than installing .pdb files for static libraries, we use the /Z7 flag
to store symbolic debugging information in the .obj files.
