From 3dbcc105d5561e18ccd0842c7baab1c835562a37 Mon Sep 17 00:00:00 2001 From: Xin Long Date: Thu, 30 Mar 2017 01:00:53 +0800 Subject: sctp: alloc stream info when initializing asoc When sending a msg without asoc established, sctp will send INIT packet first and then enqueue chunks. Before receiving INIT_ACK, stream info is not yet alloced. But enqueuing chunks needs to access stream info, like out stream state and out stream cnt. This patch is to fix it by allocing out stream info when initializing an asoc, allocing in stream and re-allocing out stream when processing init. Signed-off-by: Xin Long Signed-off-by: David S.
