2013-04-09netfilter: ipset: hash:*net*: nomatch flag not excluded on set resizeJozsef Kadlecsik
If a resize is triggered the nomatch flag is not excluded at hashing, which leads to the element missed at lookup in the resized set. Signed-off-by: Jozsef Kadlecsik <kadlec@blackhole.kfki.hu> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

2012-09-22netfilter: ipset: Support to match elements marked with "nomatch"Jozsef Kadlecsik
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 ... ...

2012-05-16netfilter: ipset: fix hash size checking in kernelJozsef Kadlecsik
The hash size must fit both into u32 (jhash) and the max value of size_t. The missing checking could lead to kernel crash, bug reported by Seblu.

2012-04-02ipset: Stop using NLA_PUT*().David S. Miller
These macros contain a hidden goto, and are thus extremely error prone and make code hard to audit. Signed-off-by: David S. Miller <davem@davemloft.net>
2012-03-07netfilter: ipset: Exceptions support added to hash:*net* typesJozsef Kadlecsik
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.

2012-03-07netfilter: ipset: use NFPROTO_ constantsJan Engelhardt
ipset is actually using NFPROTO values rather than AF (xt_set passes that along). Signed-off-by: Jan Engelhardt <jengelh@medozas.de> Signed-off-by: Jozsef Kadlecsik <kadlec@blackhole.kfki.hu> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
2011-07-21netfilter: ipset: hash:net,iface fixed to handle overlapping nets behind ↵Jozsef Kadlecsik
different interfaces If overlapping networks with different interfaces was added to the set, the type did not handle it properly. Example ipset create test hash:net,iface ipset add test 192.168.0.0/16,eth0 ipset add test 192.168.0.0/24,eth1 Now, if a packet was sent from 192.168.0.0/24,eth0, the type returned a match. In the patch the algorithm is fixed in order to correctly handle overlapping networks. Limitation: the same network cannot be stored with more than 64 different interfaces in a single set.

ipset API change With the change the sets can use any parameter available for the match and target extensions, like input/output interface. It's required for the hash:net,iface set type. Signed-off-by: Jozsef Kadlecsik <kadlec@blackhole.kfki.hu> Signed-off-by: Patrick McHardy <kaber@trash.net>

2011-06-16netfilter: ipset: support range for IPv4 at adding/deleting elements for ↵Jozsef Kadlecsik
hash:*net* types The range internally is converted to the network(s) equal to the range. Example: # ipset new test hash:net # ipset add test 10.2.0.0-10.2.1.12 # ipset list test Name: test Type: hash:net Header: family inet hashsize 1024 maxelem 65536 Size in memory: 16888 References: 0 Members: 10.2.1.12 10.2.1.0/29 10.2.0.0/24 10.2.1.8/30 Signed-off-by: Jozsef Kadlecsik <kadlec@blackhole.kfki.hu> Signed-off-by: Patrick McHardy <kaber@trash.net>
2011-06-16netfilter: ipset: set type support with multiple revisions addedJozsef Kadlecsik
A set type may have multiple revisions, for example when syntax is extended. Support continuous revision ranges in set types. Signed-off-by: Jozsef Kadlecsik <kadlec@blackhole.kfki.hu> Signed-off-by: Patrick McHardy <kaber@trash.net>
2011-06-16netfilter: ipset: fix adding ranges to hash typesJozsef Kadlecsik
When ranges are added to hash types, the elements may trigger rehashing the set. However, the last successfully added element was not kept track so the adding started again with the first element after the rehashing. Bug reported by Mr Dash Four.

2011-06-16netfilter: ipset: options and flags support added to the kernel APIJozsef Kadlecsik
The support makes possible to specify the timeout value for the SET target and a flag to reset the timeout for already existing entries. Signed-off-by: Jozsef Kadlecsik <kadlec@blackhole.kfki.hu> Signed-off-by: Patrick McHardy <kaber@trash.net>
2011-06-16netfilter: ipset: timeout can be modified for already added elementsJozsef Kadlecsik
When an element to a set with timeout added, one can change the timeout by "readding" the element with the "-exist" flag. That means the timeout value is reset to the specified one (or to the default from the set specification if the "timeout n" option is not used). Example ipset add foo 1.2.3.4 timeout 10 ipset add foo 1.2.3.4 timeout 600 -exist Signed-off-by: Jozsef Kadlecsik <kadlec@blackhole.kfki.hu> Signed-off-by: Patrick McHardy <kaber@trash.net>

2011-03-20netfilter: ipset: fix address ranges at hash:*port* typesJozsef Kadlecsik
The hash:*port* types with IPv4 silently ignored when address ranges with non TCP/UDP were added/deleted from the set and used the first address from the range only. Signed-off-by: Jozsef Kadlecsik <kadlec@blackhole.kfki.hu> Signed-off-by: Patrick McHardy <kaber@trash.net>
2011-02-01netfilter: ipset: remove unnecessary includesPatrick McHardy
None of the set types need uaccess.h since this is handled centrally in ip_set_core. Most set types additionally don't need bitops.h and spinlock.h since they use neither. tcp.h is only needed by those using before(), udp.h is not needed at all. Signed-off-by: Patrick McHardy <kaber@trash.net>
2011-02-01netfilter: ipset: hash:net,port set type supportJozsef Kadlecsik
The module implements the hash:net,port type support in four flavours: for IPv4 and IPv6, both without and with timeout support. The elements are two dimensional: IPv4/IPv6 network address/prefix and protocol/port pairs. Signed-off-by: Jozsef Kadlecsik <kadlec@blackhole.kfki.hu> Signed-off-by: Patrick McHardy <kaber@trash.net>
