From 797a7d66d2048fe8a4ac1ba58c5d4752d64b1ac4 Mon Sep 17 00:00:00 2001 From: Florian Westphal <fw@strlen.de> Date: Fri, 21 Jun 2013 16:51:30 +0200 Subject: [PATCH] netfilter: ctnetlink: send event when conntrack label was modified commit 0ceabd83875b72a29f33db4ab703d6ba40ea4c58 (netfilter: ctnetlink: deliver labels to userspace) sets the event bit when we raced with another packet, instead of raising the event bit when the label bit is set for the first time. commit 9b21f6a90924dfe8e5e686c314ddb441fb06501e (netfilter: ctnetlink: allow userspace to modify labels) forgot to update the event mask in the "conntrack already exists" case. Both issues result in CTA_LABELS attribute not getting included in the conntrack event.
