From: Oleg Drokin <[email protected]> This patch has been added to the 3.12 stable tree. If you have any objections, please let us know.
=============== commit d22e6338db7f613dd4f6095c190682fcc519e4b7 upstream. Recent changes to retry on ESTALE in linkat (commit 442e31ca5a49e398351b2954b51f578353fdf210) introduced a mountpoint reference leak and a small memory leak in case a filesystem link operation returns ESTALE which is pretty normal for distributed filesystems like lustre, nfs and so on. Free old_path in such a case. [AV: there was another missing path_put() nearby - on the previous goto retry] [js: the second path_put is not in 3.12 yet, hunk removed] Signed-off-by: Oleg Drokin: <[email protected]> Signed-off-by: Al Viro <[email protected]> Signed-off-by: Jiri Slaby <[email protected]> --- fs/namei.c | 1 + 1 file changed, 1 insertion(+) diff --git a/fs/namei.c b/fs/namei.c index 23ac50f4ee40..187cacf1c83c 100644 --- a/fs/namei.c +++ b/fs/namei.c @@ -3924,6 +3924,7 @@ retry: out_dput: done_path_create(&new_path, new_dentry); if (retry_estale(error, how)) { + path_put(&old_path); how |= LOOKUP_REVAL; goto retry; } -- 1.9.0 -- To unsubscribe from this list: send the line "unsubscribe stable" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
