Subject: [PATCH 4.19 15/42] net/sched: act_pedit: fix memory leak when IDR allocation fails
Date: Wed, 21 Nov 2018 20:05:51 +0100 [thread overview]
Message-ID: <20181121183148.653311264@linuxfoundation.org> (raw)
In-Reply-To: <20181121183147.869199006@linuxfoundation.org>
4.19-stable review patch. If anyone has any objections, please let me know.
------------------
From: Davide Caratti <dcaratti@redhat.com>
[ Upstream commit 19ab69107d3ecfb7cd3e38ad262a881be40c01a3 ]
tcf_idr_check_alloc() can return a negative value, on allocation failures
(-ENOMEM) or IDR exhaustion (-ENOSPC): don't leak keys_ex in these cases.
Fixes: 0190c1d452a9 ("net: sched: atomically check-allocate action")
