From 6fc09f10f12477bdaa54e94f9cb428bef6d81315 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Wed, 29 Aug 2012 06:49:17 +0000 Subject: [PATCH] netfilter: nfnetlink_log: fix error return code in init path Initialize return variable before exiting on an error path. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // ( if@p1 (\(ret < 0\|ret != 0\)) { ... return ret; } | ret@p1 = 0 ) ... when != ret = e1 when != &ret *if(...) { ... when != ret = e2 when forall return ret; } // Signed-off-by: Julia Lawall Signed-off-by: Pablo Neira Ayuso --- net/netfilter/nfnetlink_log.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/net/netfilter/nfnetlink_log.c b/net/netfilter/nfnetlink_log.c index 592091c1260b..14e2f3903142 100644 --- a/net/netfilter/nfnetlink_log.c +++ b/net/netfilter/nfnetlink_log.c @@ -996,8 +996,10 @@ static int __init nfnetlink_log_init(void) #ifdef CONFIG_PROC_FS if (!proc_create("nfnetlink_log", 0440, - proc_net_netfilter, &nful_file_ops)) + proc_net_netfilter, &nful_file_ops)) { + status = -ENOMEM; goto cleanup_logger; + } #endif return status; -- 2.20.1
