2013-09-30netfiler: ipset: Add net namespace for ipsetVitaly Lavrov1-1/+2
This patch adds netns support for ipset. Major changes were made in ip_set_core.c and ip_set.h. Global variables are moved to per net namespace. Added initialization code and the destruction of the network namespace ipset subsystem. In the prototypes of public functions ip_set_* added parameter "struct net*". The remaining corrections related to the change prototypes of public functions ip_set_*.

2013-09-30netfilter: ipset: Support comments in bitmap-type ipsets.Oliver Smith1-1/+3
This provides kernel support for creating bitmap ipsets with comment support. As is the case for hashes, this incurs a penalty when flushing or destroying the entire ipset as the entries must first be walked in order to free the comment strings. This penalty is of course far less than the cost of listing an ipset to userspace. Any set created without support for comments will be flushed/destroyed as before.

2013-09-30netfilter: ipset: Generalize extensions supportJozsef Kadlecsik1-73/+8
Get rid of the structure based extensions and introduce a blob for the extensions. Thus we can support more extension types easily. Signed-off-by: Jozsef Kadlecsik <kadlec@blackhole.kfki.hu>
2013-09-30netfilter: ipset: Move extension data to set structureJozsef Kadlecsik1-23/+22
Default timeout and extension offsets are moved to struct set, because all set types supports all extensions and it makes possible to generalize extension support. Signed-off-by: Jozsef Kadlecsik <kadlec@blackhole.kfki.hu>

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 Kadlecsik1-3/+3

2011-06-16netfilter: ipset: timeout can be modified for already added elementsJozsef Kadlecsik1-10/+10
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>

2011-04-04netfilter: 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 McHardy1-1/+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 set type supportJozsef Kadlecsik1-0/+588
The module implements the bitmap:ip set type in two flavours, without and with timeout support. In this kind of set one can store IPv4 addresses (or network addresses) from a given range. In order not to waste memory, the timeout version does not rely on the kernel timer for every element to be timed out but on garbage collection. All set types use this mechanism.
