From 087d975353d0cc9b7536d6ef46cd9303fceb2e17 Mon Sep 17 00:00:00 2001 From: Sowmini Varadhan Date: Fri, 31 Mar 2017 15:56:31 -0700 Subject: rds: tcp: canonical connection order for all paths with index > 0 The rds_connect_worker() has a bug in the check that enforces the canonical connection order described in the comments of rds_tcp_state_change(). The intention is to make sure that all the multipath connections are always initiated by the smaller IP address via rds_start_mprds. To achieve this, rds_connection_worker should check that cp_index > 0. Signed-off-by: Sowmini Varadhan Acked-by: Santosh Shilimkar Signed-off-by: David S.
