Subject: Core: silenced getsockopt(TCP_FASTOPEN) messages on FreeBSD.
X-Git-Url: http://www.kaiwu.me/postgresql/commit/?a=commitdiff_plain;h=4f9d83d6d7f9651246109aae837a99ea8608f3a7;p=nginx.git

Core: silenced getsockopt(TCP_FASTOPEN) messages on FreeBSD.

FreeBSD returns EINVAL when getsockopt(TCP_FASTOPEN) is called on a unix
domain socket, resulting in "getsockopt(TCP_FASTOPEN) ... failed" messages
during binary upgrade when unix domain listen sockets are present in
the configuration.  Added EINVAL to the list of ignored error codes.
