From 83731671d9e6878c0a05d309c68fb71c16d3235a Mon Sep 17 00:00:00 2001 From: Pablo Neira Ayuso Date: Mon, 6 Apr 2009 17:47:20 +0200 Subject: netfilter: ctnetlink: fix regression in expectation handling This patch fixes a regression (introduced by myself in commit 19abb7b: netfilter: ctnetlink: deliver events for conntracks changed from userspace) that results in an expectation re-insertion since __nf_ct_expect_check() may return 0 for expectation timer refreshing. This patch also removes a unnecessary refcount bump that pretended to avoid a possible race condition with event delivery and expectation timers (as said, not needed since we hold a reference to the object since until we finish the expectation setup). This also merges nf_ct_expect_related_report() and nf_ct_expect_related() which look basically the same.
