Revision a16a1647fa6b6783c2e91623e72e86f0c2adac5e authored by Pablo Neira Ayuso on 16 March 2012, 02:00:34 UTC, committed by David S. Miller on 17 March 2012, 08:47:08 UTC
Kerin Millar reported hardlockups while running `conntrackd -c' in a busy firewall. That system (with several processors) was acting as backup in a primary-backup setup. After several tries, I found a race condition between the deletion operation of ctnetlink and timeout expiration. This patch fixes this problem.
