From 12b2f117f3bf738c1a00a6f64393f1953a740bd4 Mon Sep 17 00:00:00 2001 From: Chen Gang Date: Mon, 29 Apr 2013 15:05:19 -0700 Subject: [PATCH] kernel/audit_tree.c: tree will leak memory when failure occurs in audit_trim_trees() audit_trim_trees() calls get_tree(). If a failure occurs we must call put_tree(). [akpm@linux-foundation.org: run put_tree() before mutex_lock() for small scalability improvement] Signed-off-by: Chen Gang Cc: Al Viro Cc: Eric Paris Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- kernel/audit_tree.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/kernel/audit_tree.c b/kernel/audit_tree.c index 642a89c..a291aa2 100644 --- a/kernel/audit_tree.c +++ b/kernel/audit_tree.c @@ -617,9 +617,9 @@ void audit_trim_trees(void) } spin_unlock(&hash_lock); trim_marked(tree); - put_tree(tree); drop_collected_mounts(root_mnt); skip_it: + put_tree(tree); mutex_lock(&audit_filter_mutex); } list_del(&cursor); -- 2.7.4
