From 12ce5f09acfece76aeb5021de583d156567249d5 Mon Sep 17 00:00:00 2001 From: Jozsef Kadlecsik Date: Mon, 5 Nov 2012 16:56:42 +0100 Subject: Fix range bug in hash:ip,port,net Due to the missing ininitalization at adding/deleting entries, when a plain_ip,port,net element was to be added, multiple elements were added/deleted instead. The bug came from the missing dangling default initialization. The error-prone default initialization is corrected in all hash:* types. --- kernel/net/netfilter/ipset/ip_set_hash_ip.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'kernel/net/netfilter/ipset/ip_set_hash_ip.c') diff --git a/kernel/net/netfilter/ipset/ip_set_hash_ip.c b/kernel/net/netfilter/ipset/ip_set_hash_ip.c index ec3dba5..5c0b785 100644 --- a/kernel/net/netfilter/ipset/ip_set_hash_ip.c +++ b/kernel/net/netfilter/ipset/ip_set_hash_ip.c @@ -173,6 +173,7 @@ hash_ip4_uadt(struct ip_set *set, struct nlattr *tb[], return adtfn(set, &nip, timeout, flags); } + ip_to = ip; if (tb[IPSET_ATTR_IP_TO]) { ret = ip_set_get_hostipaddr4(tb[IPSET_ATTR_IP_TO], &ip_to); if (ret) @@ -185,8 +186,7 @@ hash_ip4_uadt(struct ip_set *set, struct nlattr *tb[], if (!cidr || cidr > 32) return -IPSET_ERR_INVALID_CIDR; ip_set_mask_from_to(ip, ip_to, cidr); - } else - ip_to = ip; + } hosts = h->netmask == 32 ? 1 : 2 << (32 - h->netmask - 1); -- cgit v1.2.3
