Subject: [PATCH 11/13] netfilter: nf_tables: prohibit deletion of a table with existing sets
Date: Thu, 9 Jan 2014 18:42:41 +0000 [thread overview]
Message-ID: <1389292963-4089-12-git-send-email-kaber@trash.net> (raw)
In-Reply-To: <1389292963-4089-1-git-send-email-kaber@trash.net>
We currently leak the set memory when deleting a table that still has
sets in it. Return EBUSY when attempting to delete a table with sets.
