From 30330ee00ce077de9d459c17125573ff618bd7a9 Mon Sep 17 00:00:00 2001 From: Al Viro Date: Mon, 20 Nov 2006 17:03:18 -0800 Subject: [PATCH] [SCTP] bug: endianness problem in sctp_getsockopt_sctp_status() Again, invalid sockaddr passed to userland - host-endiand sin_port. Potential leak, again, but less dramatic than in previous case. Signed-off-by: Al Viro Signed-off-by: David S.
