From 68913a018f6082f8f90abb8ff9114435ef45dff7 Mon Sep 17 00:00:00 2001 From: Xin Long Date: Sun, 20 Aug 2017 13:38:08 +0800 Subject: [PATCH] netfilter: ipvs: do not create conn for ABORT packet in sctp_conn_schedule There's no reason for ipvs to create a conn for an ABORT packet even if sysctl_sloppy_sctp is set. This patch is to accept it without creating a conn, just as ipvs does for tcp's RST packet.
