From 3a3794573386d0cb2930a9daad5615036c06f4e2 Mon Sep 17 00:00:00 2001 From: Jozsef Kadlecsik Date: Fri, 21 Sep 2012 21:03:24 +0200 Subject: Support to match elements marked with "nomatch" in hash:*net* sets Exceptions can now be matched and we can branch according to the possible cases: a. match in the set if the element is not flagged as "nomatch" b. match in the set if the element is flagged with "nomatch" c. no match i.e. iptables ... -m set --match-set ... -j ... iptables ... -m set --match-set ... --nomatch-entries -j ... ... --- kernel/net/netfilter/ipset/ip_set_hash_ipportnet.c | 11 ++++++----- 1 file changed, 6 insertions(+), 5 deletions(-) (limited to 'kernel/net/netfilter/ipset/ip_set_hash_ipportnet.c') diff --git a/kernel/net/netfilter/ipset/ip_set_hash_ipportnet.c b/kernel/net/netfilter/ipset/ip_set_hash_ipportnet.c index 8ee9168..cb71f9a 100644 --- a/kernel/net/netfilter/ipset/ip_set_hash_ipportnet.c +++ b/kernel/net/netfilter/ipset/ip_set_hash_ipportnet.c @@ -104,10 +104,10 @@ hash_ipportnet4_data_flags(struct hash_ipportnet4_elem *dst, u32 flags) dst->nomatch = !!(flags & IPSET_FLAG_NOMATCH); } -static inline bool +static inline int hash_ipportnet4_data_match(const struct hash_ipportnet4_elem *elem) { - return !elem->nomatch; + return elem->nomatch ? -ENOTEMPTY : 1; } static inline void @@ -411,10 +411,10 @@ hash_ipportnet6_data_flags(struct hash_ipportnet6_elem *dst, u32 flags) dst->nomatch = !!(flags & IPSET_FLAG_NOMATCH); } -static inline bool +static inline int hash_ipportnet6_data_match(const struct hash_ipportnet6_elem *elem) { - return !elem->nomatch; + return elem->nomatch ? -ENOTEMPTY : 1; } static inline void @@ -697,7 +697,8 @@ hash_ipportnet_create(struct ip_set *set, struct nlattr *tb[], u32 flags) static struct ip_set_type hash_ipportnet_type __read_mostly = { .name = "hash:ip,port,net", .protocol = IPSET_PROTOCOL, - .features = IPSET_TYPE_IP | IPSET_TYPE_PORT | IPSET_TYPE_IP2, + .features = IPSET_TYPE_IP | IPSET_TYPE_PORT | IPSET_TYPE_IP2 | + IPSET_TYPE_NOMATCH, .dimension = IPSET_DIM_THREE, .family = NFPROTO_UNSPEC, .revision_min = REVISION_MIN, -- cgit v1.2.3
