* src: promote 'reject with icmp CODE' syntaxPablo Neira Ayuso2021-07-261-25/+25
| | | | | | | | | | | | | | | | | | | | | | | The kernel already assumes that that ICMP type to reject a packet is destination-unreachable, hence the user specifies the *ICMP code*. Simplify the syntax to: ... reject with icmp port-unreachable this removes the 'type' keyword before the ICMP code to reject the packet with. IIRC, the original intention is to leave room for future extensions that allow to specify both the ICMP type and the ICMP code, this is however not possible with the current inconsistent syntax. Update manpages which also refer to ICMP type. Adjust tests/py to the new syntax. Fixes: 5fdd0b6a0600 ("nft: complete reject support") Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* proto: replace vlan ether type with 8021qFlorian Westphal2021-04-031-3/+3
| | | | | | | | | | | | | Previous patches added "8021ad" mnemonic for IEEE 802.1AD frame type. This adds the 8021q shorthand for the existing 'vlan' frame type. nft will continue to recognize 'ether type vlan', but listing will now print 8021q. Adjust all test cases accordingly.

* tests: json: add missing test case outputFlorian Westphal2020-11-051-1/+1
| | | | | | | | | | | | Fix warnings and errors when running nf-test.py -j due to missing json test case updates. This also makes bridge/reject.t pass in json mode. No code changes. Fixes: 8615ed93f6e4c4 ("evaluate: enable reject with 802.1q") Fixes: fae0a0972d7a71 ("tests: py: Enable anonymous set rule with concatenated ranges in inet/sets.t") Fixes: 2a20b5bdbde8a1 ("datatype: add frag-needed (ipv4) to reject options") Signed-off-by: Florian Westphal <fw@strlen.de>
* evaluate: enable reject with 802.1qMichael Braun2020-05-281-5/+3
| | | | | | | | | | | | This enables the use nft bridge reject with bridge vlan filtering. It depends on a kernel patch to make the kernel preserve the vlan id in nft bridge reject generation.

* netlink_delinerize: remove network header dep for reject statement also in ↵Florian Westphal2019-06-191-14/+14
| | | | | | | | | | | | | | | | | | | | | bridge family add rule bridge test-bridge input reject with icmp type ... is shown as ether type ip reject type ... i.e., the dependency is not removed. Allow dependency removal -- this adds a problem where some icmp types will be shortened to 'reject', losing the icmp ipv4 dependency. Next patch resolves this problem by disabling short-hand abbreviations for bridge reject statements. Signed-off-by: Florian Westphal <fw@strlen.de> Acked-by: Pablo Neira Ayuso <pablo@netfilter.org>
* evaluate: reject: Allow icmpx in inet/bridge familiesPhil Sutter2018-08-141-0/+5
| | | | | | | | | | | | | | | | | | | Commit 3e6ab2b335142 added restraints on reject types for bridge and inet families but aparently those were too strict: If a rule in e.g. inet family contained a match which introduced a protocol dependency, icmpx type rejects were disallowed for no obvious reason. Allow icmpx type rejects in inet family regardless of protocol dependency since we either have IPv4 or IPv6 traffic in there and for both icmpx is fine. Merge restraints in bridge family with those for TCP reset since it already does what is needed, namely checking that ether proto is either IPv4 or IPv6.

* src: meta: always prefix 'meta' for almost all tokensFlorian Westphal2018-07-211-1/+1
| | | | | | | | | | | | | | | | | | 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/: rearrange tests directoryArturo Borrero2015-12-151-0/+38
Rearrange the directory to obtain a better organization of files and tests-suites. We end with a tree like this: tests | .--- py .--- shell .--- files This was suggested by Pablo.
