[stunnel-users] Stunnel 5.17 on AIX

Wed May 13 17:04:38 CEST 2015

Thanks!

I applied the patch to tls.c and I'm able to create sessions with no
problem.

The version of OpenSSL provided by IBM is built off the 1.0.1e codebase,
with backported security fixes via "iFixes" for announced CVEs. They
apparently don't backport new functionality or maybe even non-CVE bugfixes.
I'm guessing an un-patched stunnel 5.17 would work once/if they release
OpenSSL built off 1.0.1j or later.
