From 8116ffad4180b39d7a755345c1fde09da83930c0 Mon Sep 17 00:00:00 2001 From: Vlad Yasevich Date: Tue, 17 Jan 2006 11:55:17 -0800 Subject: [SCTP]: Fix bad sysctl formatting of SCTP timeout values on 64-bit m/cs. Change all the structure members that hold jiffies to be of type unsigned long. This also corrects bad sysctl formating on 64 bit architectures.

Validate and update the sk in sctp_rcv() to avoid the race where an assoc/ep could move to a different socket after we get the sk, but before the skb is added to the backlog. Also migrate the skb's in backlog queue to new sk when doing a peeloff.
