+Subject: [PATCH] unix.7: SO_PEERCRED: Mention listen(2)
+
+In case of connected AF_UNIX stream sockets, server-side credentials are
+set at the time of a call to listen(2), not when client-side calls
+connect(2).
+
+This is important if server side process changes UID/GID after listen(2)
+and before connect(2).
+
+Reproducer is available in [1].
+Behavior was confirmed in the email thread [2].
