* ebtables: Default to extrapositioned negationsPhil Sutter2024-01-101-6/+6
| | | | | | | | | | | | | | | ebtables-nft has always supported both intra- and extrapositioned negations but defaulted to intrapositioned when printing/saving rules. With commit 58d364c7120b5 ("ebtables: Use do_parse() from xshared") though, it started to warn about intrapositioned negations. So change the default to avoid mandatory warnings when e.g. loading previously dumped rulesets. Also adjust test cases, help texts and ebtables-nft.8 accordingly.

* ebtables: among: Support mixed MAC and MAC/IP entriesPhil Sutter2020-02-181-1/+1
| | | | | | | | | | | | | | Powered by Stefano's support for concatenated ranges, a full among match replacement can be implemented. The trick is to add MAC-only elements as a concatenation of MAC and zero-length prefix, i.e. a range from 0.0.0.0 till 255.255.255.255. Although not quite needed, detection of pure MAC-only matches is left in place. For those, no implicit 'meta protocol' match is added (which is required otherwise at least to keep nft output correct) and no concat type is used for the set.

* nft: bridge: Rudimental among extension supportPhil Sutter2019-11-251-0/+16
Support among match as far as possible given the limitations of nftables sets, namely limited to homogeneous MAC address only or MAC and IP address only matches. Signed-off-by: Phil Sutter <phil@nwl.cc> Acked-by: Pablo Neira Ayuso <pablo@netfilter.org>
