* Revert "ebtables: use extrapositioned negation consistently"Phil Sutter2019-02-051-7/+7
| | | | | | | | | | | | | | | | | | | | | | | This reverts commit 5f508b76a0cebaf91965ffa678089222e2d47964. While attempts at unifying syntax between arp-, eb- and iptables-nft increase the opportunity for more code-sharing, they are problematic when it comes to compatibility. Accepting the old syntax on input helps, but due to the fact that neither arptables nor ebtables support --check command we must expect for users to test existence of a rule by comparing input with output. If that happens in a script, deviating from the old syntax in output has a high chance of breaking it. Therefore revert Florian's patch changing inversion character position in output and review the old code for consistency - the only thing changed on top of the actual revert is ebtables' own copy of print_iface() to make it adhere to the intrapositioned negation scheme used throughout ebtables. Added extension tests by the reverted commit have been kept. Signed-off-by: Phil Sutter <phil@nwl.cc> Signed-off-by: Florian Westphal <fw@strlen.de>
* ebtables: use extrapositioned negation consistentlyFlorian Westphal2018-11-121-7/+7
| | | | | | | | | | | | | | in the iptables universe, we enforce extrapositioned negation: ! -i foo "-i ! foo" is not even supported anymore. At least make sure that ebtables prints the former syntax everywhere as well so we don't have a mix of both ways. Parsing of --option ! 42 will still work for backwards compat reasons.

* extensions: libebt_ip{, 6}: Drop pointless error checkingPhil Sutter2018-09-241-4/+0
| | | | | | | | | Since info->protocol is of type __u8, its value will never become -1. Apart from that, xtables_parse_protocol() calls xt_params->exit_err() in case of error, so this code is dead anyway. Signed-off-by: Phil Sutter <phil@nwl.cc> Signed-off-by: Florian Westphal <fw@strlen.de>
* ebtables-translate: suppress redundant protocolsFlorian Westphal2018-05-101-1/+1
| | | | | | | | | | | kernel would reject ip, ip6 etc. without -p ip, -p ip6. So add it. On reverse, search the match list to decide if -p has to be translated or not. Also, icmp and icmpv6 also imply l3 protocol, so no need to translate that either. Signed-off-by: Florian Westphal <fw@strlen.de>
