Subject: [PATCH 4/6] libxtables: set clone's initial data to NULL
Date: Sun, 10 Jul 2011 20:22:16 +0200 [thread overview]
Message-ID: <1310322139-28505-5-git-send-email-jengelh@medozas.de> (raw)
In-Reply-To: <1310322139-28505-1-git-send-email-jengelh@medozas.de>
Avoid a crash in xs_init_match when a clone's m->udata points at the
parent.
