Description Stefan Huber 2013-07-22 02:41:30 UTC

gentoo-sources-3.9.11 fails to compile while 3.9.10 still worked well. The compiler error is:

  CC      net/bridge/br_multicast.o
net/bridge/br_multicast.c: In function ‘br_multicast_del_pg’:
net/bridge/br_multicast.c:272:38: error: ‘struct net_bridge_mdb_entry’ has no member named ‘timer_armed’

The variable timer_armed is never defined:
grep -r -e "\<timer_armed\>" /usr/src/linux
/usr/src/linux/net/bridge/br_multicast.c:               if (!mp->ports && !mp->mglist && mp->timer_armed &&
/usr/src/linux/net/bridge/br_mdb.c:             if (!mp->ports && !mp->mglist && mp->timer_armed &&

This issue is introduced by 3.9/1600_CVE-2013-4129-bridge-fix-kernel-multicast-timer-BUG.patch in genpatches-3.9-16.base.tar.xz of gentoo-sources.

Reproducible: Always
