From dd7445ad6be3809565272b0e724f2f00c2de1989 Mon Sep 17 00:00:00 2001 From: Xin Long Date: Sat, 16 Jan 2016 20:17:17 +0800 Subject: sctp: the temp asoc's transports should not be hashed/unhashed Re-establish the previous behavior and avoid hashing temporary asocs by checking t->asoc->temp in sctp_(un)hash_transport. Also, remove the check of t->asoc->temp in __sctp_lookup_association, since they are never hashed now.
