* ipset: update my email addressJozsef Kadlecsik2019-06-051-1/+1
| | | | | | | | | It's better to use my kadlec@netfilter.org email address in the source code. I might not be able to use kadlec@blackhole.kfki.hu in the future. Signed-off-by: Jozsef Kadlecsik <kadlec@netfilter.org> Signed-off-by: Jozsef Kadlecsik <kadlec@blackhole.kfki.hu>
* Library reworked to support embedding ipset completelyJozsef Kadlecsik2018-10-181-1/+1
| | | | | | | | | | | The ipset library is rewritten/extended to support embedding ipset, so that sets can fully be managed without calling the ipset binary. The ipset binary relies completely on the new library. The libipset.3 manpage was written about the library functions and usage. Signed-off-by: Jozsef Kadlecsik <kadlec@blackhole.kfki.hu>
* Fix possible truncated output in ipset output buffer handlingJozsef Kadlecsik2017-03-121-1/+1
| | | | | | | | | | Omri Bahumi and Yoni Lavi discovered that due to the inproper handling of the ipset output buffer, the output may be truncated. So for example in an "ipset save" output, instead of 192.168.0.0/24, just 192.168.0.0 printed. If one use "ipset save" and then "ipset restore" to restore the sets, this may lead to wrong firewall rules at the end. The patch fixes the bug in the ipset code.

* print mark & mark mask in hex rather then decimalVytas Dauksa2014-01-231-3/+3
| | | | | | | modified ipset_print_mark to print in hex rather then decimal and altered accordingly test cases. Signed-off-by: Jozsef Kadlecsik <kadlec@blackhole.kfki.hu>
* add markmask for hash:ip,mark data typeVytas Dauksa2014-01-231-0/+1
| | | | | | | | | Introduce packet mark mask for hash:ip,mark data type. This allows to set mark bit filter for the ip set. Change-Id: Id8dd9ca7e64477c4f7b022a1d9c1a5b187f1c96e Signed-off-by: Jozsef Kadlecsik <kadlec@blackhole.kfki.hu>
* add hash:ip,mark data type to ipsetVytas Dauksa2014-01-081-0/+35
| | | | | | | | | | | | | | | | Introduce packet mark support with new ip,mark hash set. This includes userspace and kernelspace code, hash:ip,mark set tests and man page updates. The intended use of ip,mark set is similar to the ip:port type, but for protocols which don't use a predictable port number. Instead of port number it matches a firewall mark determined by a layer 7 filtering program like opendpi. As well as allowing or blocking traffic it will also be used for accounting packets and bytes sent for each protocol. Signed-off-by: Jozsef Kadlecsik <kadlec@blackhole.kfki.hu>
* ipset: Fix malformed output from list/save for ICMP types in port field.Sergey Popovich2013-11-111-3/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Found with ipset 6.12.1, but upstream version is still affected. Creating set of dimension three, adding elements to it and then displaying gives following results: ----------------------------------- # ipset create test-1 hash:ip,port,ip # ipset add test-1 192.0.2.1,icmp:echo-request,192.0.2.1 # ipset add test-1 192.0.2.1,icmp:ttl-zero-during-reassembly,192.0.2.1 # ipset list test-1 Name: test-1 Type: hash:ip,port,ip Header: family inet hashsize 1024 maxelem 65536 Size in memory: 16608 References: 0 Members: 192.0.2.1,icmp:ttl-zero-during-reass,192.0.2.1 192.0.2.1,icmp:echo-re,192.0.2.1 Same results with -output save|xml. ipset_print_proto_port() from lib/print.c returns incorrect length of printed string when ICMP/ICMPv6 specified in port field.

* ipset: Support comments in the userspace library.Oliver Smith2013-09-231-0/+31
| | | | | | | | | This adds support to the userspace portion of ipset for handling ipsets with the comment extension enabled. The library revision has been raised accordingly.

* Support hostnames and service names with dashJozsef Kadlecsik2012-01-141-4/+24
| | | | | | | | The square brackets are introduced as an escape mechanism to enter hostnames or service names with dash in order to avoid mixing up the dash in the name with the range notation. Problem reported by Stephen Hemminger and Marc Guardiola.
* Exceptions support added to hash:*net* typesJozsef Kadlecsik2012-01-131-1/+1
| | | | | | | | | | | | 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.
* ipset: use NFPROTO_ constantsJan Engelhardt2011-08-311-10/+10
| | | | | ipset is actually using NFPROTO values rather than AF (xt_set passes that along).
* Propagate "expose userspace-relevant parts in ip_set.h" to ipset sourceJozsef Kadlecsik2011-08-311-9/+9
| | | | | | With the header file restructuring, the ipset userspace enums IPSET_DIM_* clash with the kernel ones. In this patch the userspace is converted to use the kernel part enums and thus we got rid of userspace enums IPSET_DIM_*.

* hash:net,iface type introducedJozsef Kadlecsik2011-05-301-0/+43
| | | | | | | | | | 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
* SCTP, UDPLITE support addedJozsef Kadlecsik2011-03-181-0/+2
| | | | SCTP and UDPLITE port support added to the hash:*port* types.
* Resolving IP addresses did not work at listing/saving sets, fixed.Jozsef Kadlecsik2011-01-261-2/+2

* Avoid possible syntax clashing at saving hostnamesJozsef Kadlecsik2011-01-241-1/+2
| | | | | | If resolving is requested and the resolved hostname contains a dash character, print the unresolved IP address instead in order not to clash with the IP/hostname range syntax.
* Fix build with NDEBUG definedJozsef Kadlecsik2011-01-181-6/+12
| | | | | | | | | | | | | | | | The usage of the gcc option -Wunused-parameter interferes badly with the assert() macros. In case -DNDEBUG is specified build fails with: cc1: warnings being treated as errors print.c: In function 'ipset_print_family': print.c:92: error: unused parameter 'opt' print.c: In function 'ipset_print_port': print.c:413: error: unused parameter 'opt' print.c: In function 'ipset_print_proto': Fix it by taking into accout NDEBUG in the function arguments. Bug reported by Holger Eitzenberger.
* Listing/saving of large sets could produce broken listing, fixed.Jozsef Kadlecsik2010-12-231-1/+4
| | | | | The wrapper around getnameinfo was not snprintf-compatible and that could cause broken listing/saving for large sets.

* ipset 5: Sparc related and compatibility fixesv5.0-pre5Jozsef Kadlecsik2010-06-291-8/+8
| | | | | | | | ipset 5 is tested on Sparc, which revealed some compatibility issues and those are fixed. Kernels from 2.6.31 onward are supported. The testsuite checkings are completed to run match/target checks. The README file is updated to reflect the requirements to install and run ipset 5.
* ipset 5: last new feature addedv5.0-pre3Jozsef Kadlecsik2010-06-221-0/+73
| | | | | | | | | | | - the hash types can now store protocol together port, not only port - lots of fixes everywhere: parser, error reporting, manpage The last bits on the todo list before announcing ipset 5: - recheck all the error messages - add possibly more tests - polish manpage
* ipset 5 in an almost ready state - milestonev5.0-pre1Jozsef Kadlecsik2010-06-151-11/+16
| | | | | | | | | | | | Reworked protocol and internal interfaces, missing set types added, backward compatibility verified, lots of tests added (and thanks to the tests, bugs fixed), even the manpage is rewritten ;-). Countless changes everywhere... The missing bits before announcing ipset 5: - net namespace support - new iptables/ip6tables extension library - iptables/ip6tables match and target tests (backward/forward compatibility) - tests on catching syntax errors
