From be94db9ddac0d6ea76f479b04fb3a43314654c9f Mon Sep 17 00:00:00 2001 From: Jozsef Kadlecsik Date: Sat, 14 Jan 2012 16:42:13 +0100 Subject: netfilter: ipset: dumping error triggered removing references twice If there was a dumping error in the middle, the set-specific variable was not zeroed out and thus the 'done' function of the dumping wrongly tried to release the already released reference of the set. The already released reference was caught by __ip_set_put and triggered a kernel BUG message. Reported by Jean-Philippe Menil.
