* hash:*net*: nomatch flag not excluded on set resizeJozsef Kadlecsik2013-04-091-7/+23
| | | | | | | 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>
* netfilter: ipset: timeout values corrupted on set resizeJosh Hunt2013-02-211-1/+3
| | | | | | | | | | | If a resize is triggered on a set with timeouts enabled, the timeout values will get corrupted when copying them to the new set. This occured b/c the wrong timeout value is supplied to type_pf_elem_tadd(). This also adds simple debug statement similar to the one in type_pf_resize().

* Support to match elements marked with "nomatch" in hash:*net* setsJozsef Kadlecsik2012-09-211-0/+4
| | | | | | | | | | | | | | | 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 ... ...

* Fix cidr book keeping for hash:*net* typesJozsef Kadlecsik2012-09-101-49/+55
| | | | | | | The book-keeping of the different sized networks were bogus, fix it. The broken code could lead invalid matching in such sets when the number of different sized networks were greater than the smallest CIDR value of the networks.
* net: cleanup unsigned to unsigned intEric Dumazet2012-09-081-4/+4
| | | | | | | Use of "unsigned int" is preferred to bare "unsigned" in net tree. Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* Use MSEC_PER_SEC instead of harcoded valueJozsef Kadlecsik2012-05-151-2/+2
| | | | | David Laight and Eric Dumazet noticed that we were using hardcoded 1000 instead of MSEC_PER_SEC to calculate the timeout.
* Backport nla_put_net* functions as NLA_PUT* were removedJozsef Kadlecsik2012-05-101-0/+22
|
* ipset: Stop using NLA_PUT*().David S. Miller2012-05-102-29/+38
| | | | | | | 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>
* Fix hash size checking in kernelJozsef Kadlecsik2012-05-061-0/+16
| | | | | | 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.
* Fix timeout value overflow bug at large timeout parametersJozsef Kadlecsik2012-05-041-0/+4
| | | | | Large timeout parameters could result wrong timeout values due to an overflow at msec to jiffies conversion (reported by Andreas Herz)
* hash:net,iface timeout bug fixedJozsef Kadlecsik2012-01-131-0/+8
| | | | | Timed out entries were still matched till the garbage collector purged them out. The fix is verified in the testsuite.
* Exceptions support added to hash:*net* typesJozsef Kadlecsik2012-01-132-23/+70
| | | | | | | | | | | | 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.
* Log warning when a hash type of set gets fullJozsef Kadlecsik2012-01-101-4/+18
| | | | | If the set is full, the SET target cannot add more elements. Log warning so that the admin got notified about it.
* ipset: use NFPROTO_ constantsJan Engelhardt2011-08-311-1/+4
| | | | | ipset is actually using NFPROTO values rather than AF (xt_set passes that along).
* netfilter: ipset: expose userspace-relevant parts in ip_set.hJan Engelhardt2011-08-311-12/+14
| | | | | | | iptables's libxt_SET.c depends on these. Signed-off-by: Jan Engelhardt <jengelh@medozas.de> Signed-off-by: Jozsef Kadlecsik <kadlec@blackhole.kfki.hu>
* netfilter: ipset: avoid use of kernel-only typesJan Engelhardt2011-08-311-2/+2
| | | | | | | | | | | | | When using the xt_set.h header in userspace, one will get these gcc reports: ipset/ip_set.h:184:1: error: unknown type name "u16" In file included from libxt_SET.c:21:0: netfilter/xt_set.h:61:2: error: unknown type name "u32" netfilter/xt_set.h:62:2: error: unknown type name "u32" Signed-off-by: Jan Engelhardt <jengelh@medozas.de> Signed-off-by: Jozsef Kadlecsik <kadlec@blackhole.kfki.hu>
* Fix compiler warnings "'hash_ip4_data_next' declared inline after being called"Chris Friesen2011-07-091-1/+1
| | | | | | | | Some gcc versions warn about prototypes without "inline" when the declaration includes the "inline" keyword. The fix generates a false error message "marked inline, but without a definition" with sparse below 0.4.2. Signed-off-by: Chris Friesen <chris.friesen@genband.com>
* hash:net,iface fixed to handle overlapping nets behind different interfacesJozsef Kadlecsik2011-07-081-31/+61
| | | | | | | | | | | | | | | | | | 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.
* Make possible to hash some part of the data element only.Jozsef Kadlecsik2011-06-141-4/+10
|
* Whitespace and coding fixes detected by checkpatch.plJozsef Kadlecsik2011-05-314-6/+6
|
* hash:net,iface type introducedJozsef Kadlecsik2011-05-302-0/+11
| | | | | | | | | | The hash:net,iface type makes possible to store network address and interface name pairs in a set. It's mostly suitable for egress and ingress filtering. Examples: # ipset create test hash:net,iface # ipset add test 192.168.0.0/16,eth0 # ipset add test 192.168.0.0/24,eth1
* Add xt_action_param to the variant level kadt functions, ipset API changeJozsef Kadlecsik2011-05-272-0/+6
| | | | | | 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.
* Use unified from/to address masking and check the usageJozsef Kadlecsik2011-05-231-0/+6
|
* Adding ranges to hash types with timeout could still fail, fixedJozsef Kadlecsik2011-05-211-1/+1
| | | | | | The patch "Fix adding ranges to hash types" had got a mistypeing in the timeout variant of the hash types, which actually made the patch ineffective. Fixed!
* Removed old, not used hashing method ip_set_chashJozsef Kadlecsik2011-05-202-1253/+0
|
* Remove variable 'ret' in type_pf_tdel(), which is set but not usedJozsef Kadlecsik2011-05-201-2/+2
|
* Use proper timeout parameter to jiffies conversionJozsef Kadlecsik2011-05-201-8/+10
|
* Support range for IPv4 at adding/deleting elements for hash:*net* typesJozsef Kadlecsik2011-05-154-1/+9
| | | | | | | | | | | | | | | | | | | 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
* Set type support with multiple revisions addedJozsef Kadlecsik2011-05-111-2/+4
| | | | | A set type may have multiple revisions, for example when syntax is extended. Support continuous revision ranges in set types.
* Fix adding ranges to hash typesJozsef Kadlecsik2011-05-062-4/+20
| | | | | | 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.
* Support listing setnames and headers tooJozsef Kadlecsik2011-04-181-0/+4
| | | | | | Current listing makes possible to list sets with full content only. The patch adds support partial listings, i.e. listing just the existing setnames or listing set headers, without set members.
* Options and flags support added to the kernel APIJozsef Kadlecsik2011-04-184-8/+30
| | | | | | The support makes possible to specify the timeout value for the SET target and a flag to reset the timeout for already existing entries.
* Timeout can be modified for already added elementsJozsef Kadlecsik2011-03-272-8/+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
* References are protected by rwlock instead of mutexJozsef Kadlecsik2011-03-252-3/+2
| | | | | | | 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.
* SCTP, UDPLITE support addedJozsef Kadlecsik2011-03-181-0/+2
| | | | SCTP and UDPLITE port support added to the hash:*port* types.
* hash:ip,port* types with IPv4Jozsef Kadlecsik2011-03-181-0/+10
| | | | | | The hash:ip,port* types with IPv4 silently ignored when address ranges with non TCP/UDP were added/deleted from the set and the first address from the range was only used.
* netfilter: ipset: fix linking with CONFIG_IPV6=nPatrick McHardy2011-02-031-0/+10
| | | | | | | | | Add some #ifdefs to unconditionally return false in ip_set_get_ip6_port() when CONFIG_IPV6=n and convert to ipv6_skip_exthdr() to avoid pulling in the ip6_tables module when loading ipset. Signed-off-by: Patrick McHardy <kaber@trash.net>
* netfilter: ipset: add missing include to xt_set.hPatrick McHardy2011-02-011-0/+1
| | | | Signed-off-by: Patrick McHardy <kaber@trash.net>
* Separate ipset errnos completely from system ones and bump protocol version.Jozsef Kadlecsik2011-01-311-3/+3
|
* Move the type specifici attribute validation to the coreJozsef Kadlecsik2011-01-272-4/+7
| | | | | | The type specific attribute validation can be moved to the ipset core. That way it's done centrally and thus can be eliminated from the individual set types (suggested by Patrick McHardy).
* Use vzalloc() instead of __vmalloc()Jozsef Kadlecsik2011-01-262-5/+3
| | | | Use vzalloc() if kernel version supports it. (Eric Dumazet, Patrick McHardy)
* Correct the error codes: use ENOENT and EMSGSIZEJozsef Kadlecsik2011-01-261-5/+7
| | | | Use correct error codes (Patrick McHardy's review)
* Fix trailing whitespaces and pr_* messagesJozsef Kadlecsik2011-01-212-15/+13
| | | | | | Some trailing whitespace slipped in, those are removed. With the deleted ip_set_kernel.h, the pr_* messages lost the trailing "\n" character. The messages were completed with it.
* Un-inline functions which are not small enoughJozsef Kadlecsik2011-01-201-7/+7
