Subject: [PATCH net 6/6] ice: switch: fix potential memleak in ice_add_adv_recipe()
Date: Tue, 31 Jan 2023 13:37:03 -0800 [thread overview]
Message-ID: <20230131213703.1347761-7-anthony.l.nguyen@intel.com> (raw)
In-Reply-To: <20230131213703.1347761-1-anthony.l.nguyen@intel.com>
From: Zhang Changzhong <zhangchangzhong@huawei.com>
When ice_add_special_words() fails, the 'rm' is not released, which will
lead to a memory leak. Fix this up by going to 'err_unroll' label.
Compile tested only.
Fixes: 8b032a55c1bd ("ice: low level support for tunnels")
