Revert "af_unix: dont send SCM_CREDENTIAL when dest socket is NULL" This reverts commit 14134f6584212d585b310ce95428014b653dfaf6. The problem that the above patch was meant to address is that af_unix messages are not being coallesced because we are sending unnecesarry credentials. Not sending credentials in maybe_add_creds totally breaks unconnected unix domain sockets that wish to send credentails to other sockets. In practice this break some versions of udev because they receive a message and the sending uid is bogus so they drop the message. Reported-by: Sven Joachim <svenjoac@gmx.de> Signed-off-by: "Eric W.
