Subject: [PATCH] umask in POSIX message queues
Date: Mon, 26 Sep 2005 12:44:24 +0200 (CEST) [thread overview]
Message-ID: <Pine.GSO.4.58.0509261218080.5216@Juliusz> (raw)
Hi
All kernels (form 2.6.6) ignore umask when creating new queues via
mq_open (when creating with open() on mqueue fs it is ok of course).
According to specification this a bug. The following trivial patch fixes
this. It should apply cleanly to any current kernel. Please apply.
