Date: Tue, 24 Mar 2015 16:45:23 +0100 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-kernel@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, stable@...r.kernel.org, Al Viro <viro@...iv.linux.org.uk>, "David S. Miller" <davem@...emloft.net> Subject: [PATCH 3.19 014/123] caif: fix MSG_OOB test in caif_seqpkt_recvmsg() 3.19-stable review patch. If anyone has any objections, please let me know. ------------------ From: Al Viro <viro@...IV.linux.org.uk> [ Upstream commit 3eeff778e00c956875c70b145c52638c313dfb23 ] It should be checking flags, not msg->msg_flags. It's ->sendmsg() instances that need to look for that in ->msg_flags, ->recvmsg() ones (including the other ->recvmsg() instance in that file, as well as unix_dgram_recvmsg() this one claims to be imitating) check in flags. Braino had been introduced in commit dcda13 ("caif: Bugfix - use MSG_TRUNC in receive") back in 2010, so it goes quite a while back.
