2012-04-02ipset: Stop using NLA_PUT*().David S. Miller1-17/+20
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: use NFPROTO_ constantsJan Engelhardt1-5/+5
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>
2011-11-21netfilter: ipset: suppress compile-time warnings in ip_set_hash_ipport*.cJozsef Kadlecsik1-1/+1
warning: 'ip_to' may be used uninitialized in this function 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 Kadlecsik1-2/+4
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.

2011-06-16netfilter: ipset: add xt_action_param to the variant level kadt functions, ↵Jozsef Kadlecsik1-0/+2
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: use unified from/to address masking and check the usageJozsef Kadlecsik1-2/+1
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 Kadlecsik1-1/+2
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 Kadlecsik1-5/+26
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 Kadlecsik1-8/+8
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 Kadlecsik1-6/+6
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>
2011-04-13netfilter: ipset: SCTP, UDPLITE support addedJozsef Kadlecsik1-1/+1
SCTP and UDPLITE port support added to the hash:*port* set types. 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 Kadlecsik1-24/+10
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 McHardy1-3/+0
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:ip,port set type supportJozsef Kadlecsik1-0/+547
The module implements the hash:ip,port type support in four flavours: for IPv4 and IPv6, both without and with timeout support. The elements are two dimensional: IPv4/IPv6 address and protocol/port pairs. The port is interpeted for TCP, UPD, ICMP and ICMPv6 (at the latters as type/code of course).
