* ct: Add support for the 'id' keyBrett Mastbergen2020-05-011-0/+2
| | | | | | | | | The 'id' key allows for matching on the id of the conntrack entry. v2: Remove ct_id_type Signed-off-by: Brett Mastbergen <brett.mastbergen@gmail.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* tests: py: add bit-shift tests.Jeremy Sowden2020-02-071-0/+1
| | | | | | | | Add a couple of Python test-cases for setting the CT mark to a bitwise expression derived from the packet mark and vice versa. Signed-off-by: Jeremy Sowden <jeremy@azazel.net> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* netlink_delinearize: fix wrong conversion to "list" in ct markFernando Fernandez Mancera2019-09-101-0/+1
| | | | | | | | | | | We only prefer "list" representation in "ct event". For any other type of "ct" use the "or" representation so nft prints "ct mark set ct mark | 0x00000001" instead of "ct mark set ct mark,0x00000001".

* ct: support for NFT_CT_{SRC,DST}_{IP,IP6}Pablo Neira Ayuso2019-06-211-2/+2
| | | | | | | | | | | | | | | | | These keys are available since kernel >= 4.17. You can still use NFT_CT_{SRC,DST}, however, you need to specify 'meta protocol' in first place to provide layer 3 context. Note that NFT_CT_{SRC,DST} are broken with set, maps and concatenations. This patch is implicitly fixing these cases. If your kernel is < 4.17, you can still use address matching via explicit meta nfproto: meta nfproto ipv4 ct original saddr 1.2.3.4 Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

* tests: py: remove single-value-anon-set test casesFlorian Westphal2019-05-191-2/+0
| | | | | | | | future change will rewrite all single-element anon sets to a cmp op. Retain a few test cases to later check that the rewrite is correct, but remove all others. Signed-off-by: Florian Westphal <fw@strlen.de>
* src: meta: always prefix 'meta' for almost all tokensFlorian Westphal2018-07-211-3/+3
| | | | | | | | | | | | | | | | | | got following bug report: nft add ... ct mark set mark and 0x10 ... always sets 0. What reporter meant to write instead was 'ct mark', not 'mark'. We can't just remove support for 'mark' and force 'meta mark', but we can start to discourage it by printing meta prefix too. Later on, we could start to print deprecation warning if needed. Followup patch can also change "iifname" etc. to "meta iifname". Signed-off-by: Florian Westphal <fw@strlen.de>

* tests/py: Use libnftables instead of calling nft binaryPhil Sutter2018-04-111-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds a simple nftables Python class in py/nftables.py which gives access to libnftables API via ctypes module. nft-test.py is extended to make use of the above class instead of calling nft binary. Since command line formatting had to be touched anyway, this patch also streamlines things a bit by introducing __str__ methods to classes Table and Chain and making extensive use of format strings instead of onerously adding all string parts together. Since the called commands don't see a shell anymore, all shell meta character escaping done in testcases is removed. The visible effects of this change are: * Four new warnings in ip/flowtable.t due to changing objref IDs (will be addressed later in a patch to libnftnl). * Reported command line in warning and error messages changed slightly for obvious reasons. * Reduction of a full test run's runtime by a factor of four.

Actually, this failure is "ok; we can't find upper layer protocol in this case, but even if we'd "fix" this it is still non-sensical, meta nfproto ipv4, but family is ipv6 --> rule would never match. First move this to an inet-specific test. A followup patch will reject meta nfproto for all families except inet.

* tests: py: Add test for ambiguity while setting the valueShyam Saini2017-06-181-0/+5
| | | | | | | | | | | | | | | | | | | | | This test checks bug identified and fixed in the commit mentioned below In a statement if there are multiple src data then it would be totally ambiguous to decide which value to set. Before the commit was made it returned 134(BUG), but now it returns 1 i.e, an error message. Following rules tests ambiguity while setting the value: $ sudo nft add rule ip test-ip4 output ct mark set {0x11333, 0x11} <cmdline>:1:41-55: Error: you cannot use a set here, unknown value to use add rule ip test-ip4 output ct mark set {0x11333, 0x11} ~~~~~~~~~~~~^^^^^^^^^^^^^^^ Test: 986dea8 ("evaluate: avoid reference to multiple src data in statements which set values") Signed-off-by: Shyam Saini <mayhs11saini@gmail.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

* ct: fix inet/bridge/netdev family handling for saddr/daddrFlorian Westphal2017-06-061-0/+4
| | | | | | | | | | | | | "ct orignal saddr" has an invalid data type, as the address can be either ipv4 or ipv6. For some cases we could infer it from the rhs, but there are cases where we don't have any information, e.g. when passing ct original saddr to jhash expression. So do the same thing that we do for "rt nexthop" -- error out and hint to user they need to specifiy the desired address type with "meta nfproto".

* ct: add average bytes per packet counter supportLiping Zhang2017-01-161-0/+3
| | | | | | | | | | | | | | | | | Similar to connbytes extension in iptables, now you can use it to match average bytes per packet a connection has transferred so far. For example, match avgpkt in "BOTH" diretion: # nft add rule x y ct avgpkt \> 100 Match avgpkt in reply direction: # nft add rule x y ct reply avgpkt \< 900 Or match avgpkt in original direction: # nft add rule x y ct original avgpkt \> 200 Signed-off-by: Liping Zhang <zlpnobody@gmail.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
