* Fix libipset library release versioningJozsef Kadlecsik2014-03-071-1/+1
| | | | | | Patch "add hash:ip,mark data type to ipset" broke the API and library release versioning with not incrementing "current", just "age", which is fixed here. Reported by Mathieu Bridon.

* ipset: add forceadd kernel support for hash set typesJosh Hunt2014-03-0414-12/+40
| | | | | | | | | | | | | | | | | | Adds a new property for hash set types, where if a set is created with the 'forceadd' option and the set becomes full the next addition to the set may succeed and evict a random entry from the set. To keep overhead low eviction is done very simply. It checks to see which bucket the new entry would be added. If the bucket's pos value is non-zero (meaning there's at least one entry in the bucket) it replaces the first entry in the bucket. If pos is zero, then it continues down the normal add process. This property is useful if you have a set for 'ban' lists where it may not matter if you release some entries from the set early.

* kernel: uapi: fix MARKMASK attr ABI breakageFlorian Westphal2014-02-142-4/+4
| | | | | | | | | | | | | | commit 2dfb973c0dcc6d2211 (add markmask for hash:ip,mark data type) inserted IPSET_ATTR_MARKMASK in-between other enum values, i.e. changing values of all further attributes. This causes 'ipset list' segfault on existing kernels since ipset no longer finds IPSET_ATTR_MEMSIZE (it has a different value on kernel side). Jozsef points out it should be moved below IPSET_ATTR_MARK which works since there is some extra reserved space after that value.

* add hash:ip,mark data type to ipsetVytas Dauksa2014-01-0831-7/+1125
| | | | | | | | | | | | | | | | Introduce packet mark support with new ip,mark hash set. This includes userspace and kernelspace code, hash:ip,mark set tests and man page updates. The intended use of ip,mark set is similar to the ip:port type, but for protocols which don't use a predictable port number. Instead of port number it matches a firewall mark determined by a layer 7 filtering program like opendpi. As well as allowing or blocking traffic it will also be used for accounting packets and bytes sent for each protocol. Signed-off-by: Jozsef Kadlecsik <kadlec@blackhole.kfki.hu>

* ipset: Follow manual page behavior for SET target on list:setSergey Popovich2013-11-111-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ipset(8) for list:set says: The match will try to find a matching entry in the sets and the target will try to add an entry to the first set to which it can be added. However real behavior is bit differ from described. Consider example: # ipset create test-1-v4 hash:ip family inet # ipset create test-1-v6 hash:ip family inet6 # ipset create test-1 list:set # ipset add test-1 test-1-v4 # ipset add test-1 test-1-v6 # iptables -A INPUT -p tcp --destination-port 25 -j SET --add-set test-1 src # ip6tables -A INPUT -p tcp --destination-port 25 -j SET --add-set test-1 src And then when iptables/ip6tables rule matches packet IPSET target tries to add src from packet to the list:set test-1 where first entry is test-1-v4 and the second one is test-1-v6. For IPv4, as it first entry in test-1 src added to test-1-v4 correctly, but for IPv6 src not added! Placing test-1-v6 to the first element of list:set makes behavior correct for IPv6, but brokes for IPv4. This is due to result, returned from ip_set_add() and ip_set_del() from net/netfilter/ipset/ip_set_core.c when set in list:set equires more parameters than given or address families do not match (which is this case). It seems wrong returning 0 from ip_set_add() and ip_set_del() in this case, as 0 should be returned only when an element successfuly added/deleted to/from the set, contrary to ip_set_test() which returns 0 when no entry exists and >0 when entry found in set.
