Subject: [PATCH AUTOSEL 4.14 06/21] ixgbe: Fix memleak in ixgbe_configure_clsu32
Date: Tue, 16 Mar 2021 20:59:05 -0400 [thread overview]
Message-ID: <20210317005920.726931-6-sashal@kernel.org> (raw)
In-Reply-To: <20210317005920.726931-1-sashal@kernel.org>
From: Dinghao Liu <dinghao.liu@zju.edu.cn>
[ Upstream commit 7a766381634da19fc837619b0a34590498d9d29a ]
When ixgbe_fdir_write_perfect_filter_82599() fails,
input allocated by kzalloc() has not been freed,
which leads to memleak.
