WITH SSL ENABLED
Problem:
It was reported that MySQL community utilities cannot connect to a MySQL
Enterprise 5.6.x server with SSL configured. We can reproduce the issue
when we try to connect an MySQL Enterprise Server with a MySQL Client with
--ssl-ca parameter enabled.
We get an ERROR 2026 (HY000): SSL connection error: unknown error number.
Solution:
The root cause of the problem was determined to be the difference in handling
of the certificates by OpenSSL(Enterprise) and yaSSL(Community). OpenSSL expects
a blank certificate to be sent when a parameter (ssl-ca, or ssl-cert or ssl-key)
has not been specified.On the other hand yaSSL doesn't send any certificate and
since OpenSSL does not expect this behaviour it returns an Unknown SSL error.
The issue was resolved by yaSSL adding capability to send blank certificate when
any of the parameter is missing.
$SUBJ$
1. Took a diff between the previous base version and the
mysql sources.
2. Added the new 2.1.4 base version.
3. Reviewed and re-applied the diff from step #1.
