From 24b35d0b8950407ce85eefef18576d54f1e2c20e Mon Sep 17 00:00:00 2001 From: Jozsef Kadlecsik Date: Fri, 13 Jan 2012 22:52:44 +0100 Subject: Exceptions support added to hash:*net* types The "nomatch" keyword and option is added to the hash:*net* types, by which one can add exception entries to sets. Example: ipset create test hash:net ipset add test 192.168.0/24 ipset add test 192.168.0/30 nomatch In this case the IP addresses from 192.168.0/24 except 192.168.0/30 match the elements of the set. --- lib/ipset_hash_net.c | 67 ++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 67 insertions(+) (limited to 'lib/ipset_hash_net.c') diff --git a/lib/ipset_hash_net.c b/lib/ipset_hash_net.c index 76269f0..0fd2608 100644 --- a/lib/ipset_hash_net.c +++ b/lib/ipset_hash_net.c @@ -162,3 +162,70 @@ struct ipset_type ipset_hash_net1 = { .usage = hash_net1_usage, }; +static const struct ipset_arg hash_net2_add_args[] = { + { .name = { "timeout", NULL }, + .has_arg = IPSET_MANDATORY_ARG, .opt = IPSET_OPT_TIMEOUT, + .parse = ipset_parse_uint32, .print = ipset_print_number, + }, + { .name = { "nomatch", NULL }, + .has_arg = IPSET_NO_ARG, .opt = IPSET_OPT_NOMATCH, + .parse = ipset_parse_flag, .print = ipset_print_flag, + }, + { }, +}; + +static const char hash_net2_usage[] = +"create SETNAME hash:net\n" +" [family inet|inet6]\n" +" [hashsize VALUE] [maxelem VALUE]\n" +" [timeout VALUE]\n" +"add SETNAME IP[/CIDR]|FROM-TO [timeout VALUE] [nomatch]\n" +"del SETNAME IP[/CIDR]|FROM-TO\n" +"test SETNAME IP[/CIDR]\n\n" +"where depending on the INET family\n" +" IP is an IPv4 or IPv6 address (or hostname),\n" +" CIDR is a valid IPv4 or IPv6 CIDR prefix.\n" +" IP range is not supported with IPv6.\n"; + +struct ipset_type ipset_hash_net2 = { + .name = "hash:net", + .alias = { "nethash", NULL }, + .revision = 2, + .family = NFPROTO_IPSET_IPV46, + .dimension = IPSET_DIM_ONE, + .elem = { + [IPSET_DIM_ONE - 1] = { + .parse = ipset_parse_ip4_net6, + .print = ipset_print_ip, + .opt = IPSET_OPT_IP + }, + }, + .args = { + [IPSET_CREATE] = hash_net_create_args, + [IPSET_ADD] = hash_net2_add_args, + }, + .mandatory = { + [IPSET_CREATE] = 0, + [IPSET_ADD] = IPSET_FLAG(IPSET_OPT_IP), + [IPSET_DEL] = IPSET_FLAG(IPSET_OPT_IP), + [IPSET_TEST] = IPSET_FLAG(IPSET_OPT_IP), + }, + .full = { + [IPSET_CREATE] = IPSET_FLAG(IPSET_OPT_HASHSIZE) + | IPSET_FLAG(IPSET_OPT_MAXELEM) + | IPSET_FLAG(IPSET_OPT_TIMEOUT), + [IPSET_ADD] = IPSET_FLAG(IPSET_OPT_IP) + | IPSET_FLAG(IPSET_OPT_CIDR) + | IPSET_FLAG(IPSET_OPT_IP_TO) + | IPSET_FLAG(IPSET_OPT_TIMEOUT) + | IPSET_FLAG(IPSET_OPT_NOMATCH), + [IPSET_DEL] = IPSET_FLAG(IPSET_OPT_IP) + | IPSET_FLAG(IPSET_OPT_CIDR) + | IPSET_FLAG(IPSET_OPT_IP_TO), + [IPSET_TEST] = IPSET_FLAG(IPSET_OPT_IP) + | IPSET_FLAG(IPSET_OPT_CIDR), + }, + + .usage = hash_net2_usage, +}; + -- cgit v1.2.3
