Subject: [PATCH v2] fs: affs: fix a memory leak in affs_remount
Date: Mon, 30 Sep 2019 16:01:10 -0500 [thread overview]
Message-ID: <20190930210114.6557-1-navid.emamdoost@gmail.com> (raw)
In-Reply-To: <ec7d3fdb-445b-7f4e-d6e6-77c6ae9a5732@web.de>
In affs_remount if data is provided it is duplicated into new_opts.
The allocated memory for new_opts is only released if pare_options fail.
The release for new_opts is added.
Fixes: c8f33d0bec99 ("affs: kstrdup() memory handling")
Signed-off-by: Navid Emamdoost <navid.emamdoost@gmail.com>
