From 25b9d11c002e5c71840c2a6733c5009d78f2c9db Mon Sep 17 00:00:00 2001 From: Matt Caswell Date: Wed, 1 Jun 2016 23:15:12 +0100 Subject: Handle inability to create AFALG socket Some Linux platforms have a suitably recent kernel to support AFALG, but apparently you still can't actually create an afalg socket. This extends the afalg_chk_platform() function to additionally check whether we can create an AFALG socket. We also amend the afalgtest to not report a failure to load the engine as a test failure. A failure to load is almost certainly due to platform environmental issues, and not an OpenSSL problem.
