Subject: [Ocfs2-devel] [PATCH 1/1] ocfs2: Fix panic on kfree(xattr->name)
Date: Fri, 28 Mar 2014 14:44:57 -0700 [thread overview]
Message-ID: <1396043097-7192-2-git-send-email-srinivas.eeda@oracle.com> (raw)
In-Reply-To: <1396043097-7192-1-git-send-email-srinivas.eeda@oracle.com>
From: Tetsuo Handa <penguin-kernel@I-love.SAKURA.ne.jp>
Commit 9548906b 'xattr: Constify ->name member of "struct xattr".' missed that
ocfs2 is calling kfree(xattr->name). As a result, kernel panic occurs upon
calling kfree(xattr->name) because xattr->name refers static constant names.
This patch removes kfree(xattr->name) from ocfs2_mknod() and ocfs2_symlink().
