From 9494c7c5774d64a84a269aad38c153c4dbff97e6 Mon Sep 17 00:00:00 2001 From: Wei Yongjun <yjwei@cn.fujitsu.com> Date: Tue, 12 Apr 2011 15:22:22 +0000 Subject: [PATCH] sctp: fix oops while removed transport still using as retran path Since we can not update retran path to unconfirmed transports, when we remove a peer, the retran path may not be update if the other transports are all unconfirmed, and we will still using the removed transport as the retran path. This may cause panic if retrasnmit happen. Signed-off-by: Wei Yongjun <yjwei@cn.fujitsu.com> Signed-off-by: David S.
