* netfilter: ipset: Add support for new bitmask parameterVishwanath Pai8 days4-2/+9
| | | | | | | | | | | | | | | Add a new parameter to complement the existing 'netmask' option. The main difference between netmask and bitmask is that bitmask takes any arbitrary ip address as input, it does not have to be a valid netmask. The name of the new parameter is 'bitmask'. This lets us mask out arbitrary bits in the ip address, for example: ipset create set1 hash:ip bitmask 255.128.255.0 ipset create set2 hash:ip,port family inet6 bitmask ffff::ff80 Signed-off-by: Vishwanath Pai <vpai@akamai.com> Signed-off-by: Joshua Hunt <johunt@akamai.com> Signed-off-by: Jozsef Kadlecsik <kadlec@netfilter.org>
* add ipset to nftables translation infrastructurePablo Neira Ayuso2021-06-262-1/+8
| | | | | | | | | | | | | | | | | | | | | This patch provides the ipset-translate utility which allows you to translate your existing ipset file to nftables. The ipset-translate utility is actually a symlink to ipset, which checks for 'argv[0] == ipset-translate' to exercise the translation path. You can translate your ipset file through: ipset-translate restore < sets.ipt This patch reuses the existing parser and API to represent the sets and the elements. There is a new ipset_xlate_set dummy object that allows to store a created set to fetch the type without interactions with the kernel.

* Silence unused-but-set-variable warningsJozsef Kadlecsik2021-02-191-0/+2
| | | | | | | | | | | | | | | | | | | | When ipset is compiled in non-debug mode, in some environments warnings treated as errors emitted: session.c: In function 'build_msg': session.c:1985:28: warning: variable 'type' set but not used [-Wunused-but-set-variable] const struct ipset_type *type; ^ session.c:2030:28: warning: variable 'type' set but not used [-Wunused-but-set-variable] const struct ipset_type *type; ^ Fix it by hiding the unused variable definitions/settings in non-debug mode.

* Add bucketsize parameter to all hash typesJozsef Kadlecsik2020-09-213-1/+5
| | | | | | | | | The parameter defines the upper limit in any hash bucket at adding new entries from userspace - if the limit would be exceeded, ipset doubles the hash size and rehashes. It means the set may consume more memory but gives faster evaluation at matching in the set. Signed-off-by: Jozsef Kadlecsik <kadlec@netfilter.org>

* ipset: Add wildcard support to net,ifaceKristian Evensen2019-10-313-1/+6
| | | | | | | | | | | | | | | | | | | | | The net,iface equal functions currently compares the full interface names. In several cases, wildcard (or prefix) matching is useful. For example, when converting a large iptables rule-set to make use of ipset, I was able to significantly reduce the number of set elements by making use of wildcard matching. Wildcard matching is enabled by adding "wildcard" when adding an element to a set. Internally, this causes the IPSET_FLAG_IFACE_WILDCARD-flag to be set. When this flag is set, only the initial part of the interface name is used for comparison. Wildcard matching is done per element and not per set, as there are many cases where mixing wildcard and non-wildcard elements are useful. This means that is up to the user to handle (avoid) overlapping interface names. Signed-off-by: Kristian Evensen <kristian.evensen@gmail.com> Signed-off-by: Jozsef Kadlecsik <kadlec@netfilter.org>

* Add missing functions to libipset.mapJozsef Kadlecsik2018-11-281-4/+3
| | | | | Some new functions was not added to libipset.map at the previous release, fix it.
* Implement sorting for hash types in the ipset toolJozsef Kadlecsik2018-11-261-0/+104
| | | | | Support listing/saving with sorted entries for the hash types. (bitmap and list types are automatically sorted.)
* Introduction of new commands and protocol version 7Jozsef Kadlecsik2018-10-276-8/+16
| | | | | | | | | | | Two new commands (IPSET_CMD_GET_BYNAME, IPSET_CMD_GET_BYINDEX) are introduced. The new commands makes possible to eliminate the getsockopt operation (in iptables set/SET match/target) and thus use only netlink communication between userspace and kernel for ipset. With the new protocol version, userspace can exactly know which functionality is supported by the running kernel. Both the kernel and userspace is fully backward compatible.
* Prepare the ipset tool to handle multiple protocol versionsJozsef Kadlecsik2018-10-221-2/+3
| | | | | From now on the "version" command asks the kernel protocol version too and reports if the userspace - kernel protocols do not match.
* Fix warning message handlingJozsef Kadlecsik2018-10-223-10/+16
| | | | | Warning messages were not printed and handled properly, the patch fixes the issue.
* Library reworked to support embedding ipset completelyJozsef Kadlecsik2018-10-185-67/+119
| | | | | | | | | | | 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>

* Userspace revision handling is reworkedJozsef Kadlecsik2018-01-022-3/+84
| | | | | | | | | | | In order to make it simpler and more straightforward to express the revisions of the set type, all keywords and their parsing are separated from the individual set types. All backward compatibility arguments are recognized and ignored arguments are supported. Recognized but ignored arguments will be removed in a later release.
* Fix the include guards on the include/libipset/linux_ip_set*.hJozsef Kadlecsik2017-09-144-12/+19
| | | | | | | The include guards did not prevent including the "same" userspace and kernel header files. Fixes bugzilla id #1139, reported and solution suggested by Quentin Armitage.

* Add element count to all set types headerJozsef Kadlecsik2015-06-251-3/+0
| | | | | | It is better to list the set elements for all set types, thus the header information is uniform. Element counts are therefore added to the bitmap and list types.
* Add element count to hash headersEric B Munson2015-06-191-0/+3
| | | | | | | | | | | | | | | | | | | | | | It would be useful for userspace to query the size of an ipset hash, however, this data is not exposed to userspace outside of counting the number of member entries. This patch uses the attribute IPSET_ATTR_ELEMENTS to indicate the size in the the header that is exported to userspace. This field is then printed by the userspace tool for hashes. Because it is only meaningful for hashes to report their size, the output is conditional on the set type. To do this checking the MATCH_TYPENAME macro was moved to utils.h. The bulk of this patch changes the expected test suite to account for the change in output.

* kernel: uapi: fix MARKMASK attr ABI breakageFlorian Westphal2014-02-141-2/+2
| | | | | | | | | | | | | | commit 2dfb973c0dcc6d2211 (add markmask for hash:ip,mark data type) inserted IPSET_ATTR_MARKMASK in-between other enum values, i.e. changing values of all further attributes. This causes 'ipset list' segfault on existing kernels since ipset no longer finds IPSET_ATTR_MEMSIZE (it has a different value on kernel side). Jozsef points out it should be moved below IPSET_ATTR_MARK which works since there is some extra reserved space after that value.

* add hash:ip,mark data type to ipsetVytas Dauksa2014-01-084-0/+8
| | | | | | | | | | | | | | | | 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>
