Subject: [PATCH] daemon: ignore ENOTSOCK from setsockopt
Date: Mon, 18 Jul 2016 04:59:11 +0000	[thread overview]
Message-ID: <20160718045911.GA7227@starla> (raw)

In inetd mode, we are not guaranteed stdin or stdout is a
socket; callers could filter the data through a pipe
or be testing with regular files.

This prevents t5802 from polluting syslog.
