Description:
  I built MySQL server from the source with enabled HAVE_OPENSSL. I've tried to test this build and fall into situation when MySQL server closes the connection because of timeout after short period of time(5 sec). I checked all the related server variables and they setup by default with reasonable timeout. I debug the server code and found out that connection timeout(5sec) fires after connection phase, when server waits for incomming command. I looked into viossl.c and found following code: 
void vio_ssl_timeout(Vio *vio __attribute__((unused)), 
uint timeout __attribute__((unused))) 
{ 
/* Not yet implemented (non critical) */ 
} 

   

regards, 
Oleg

How to repeat:
  Run MySQLd which supports SSL. Create a client application that connects to the server thru SSL and makes 10sec timeout after connect. After timeout next request to the server will fail because of socket is closed.

Suggested fix:
I copied implementation of this method from viosocket.c and seems like it fixes the issue.

Yes I already experienced this issue. The work-around I found was
to start the server with

--connect-timeout=5000 # or any suitable value
