2012-05-09netfilter: Convert compare_ether_addr to ether_addr_equalJoe Perches1-2/+2
Use the new bool function ether_addr_equal to add some clarity and reduce the likelihood for misuse of compare_ether_addr for sorting.

2012-04-02ipset: Stop using NLA_PUT*().David S. Miller1-19/+24
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 Engelhardt1-2/+2
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>

2011-06-16netfilter: ipset: add xt_action_param to the variant level kadt functions, ipset API changeJozsef Kadlecsik1-0/+1
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: 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 Kadlecsik1-1/+1
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 Kadlecsik1-4/+4
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 Kadlecsik1-10/+11
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: bitmap:ip,mac type requires "src" for MACJozsef Kadlecsik1-0/+4
Enforce that the second "src/dst" parameter of the set match and SET target must be "src", because we have access to the source MAC only in the packet. The previous behaviour, that the type required the second parameter but actually ignored the value was counter-intuitive and confusing.

2011-03-29netfilter: ipset: References are protected by rwlock instead of mutexJozsef Kadlecsik1-2/+1
The timeout variant of the list:set type must reference the member sets. However, its garbage collector runs at timer interrupt so the mutex protection of the references is a no go. Therefore the reference protection is converted to rwlock. 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: bitmap:ip,mac type supportJozsef Kadlecsik1-0/+655
The module implements the bitmap:ip,mac set type in two flavours, without and with timeout support. In this kind of set one can store IPv4 address and (source) MAC address pairs. The type supports elements added without the MAC part filled out: when the first matching from kernel happens, the MAC part is automatically filled out. The timing out of the elements stars when an element is complete in the IP,MAC pair. Signed-off-by: Jozsef Kadlecsik <kadlec@blackhole.kfki.hu> Signed-off-by: Patrick McHardy <kaber@trash.net>
