Subject: [PATCH] etc: Drop xtables.conf
The file is not used since the commit this one fixes. Also it wasn't
installed until recently, when commit 3822a992bc277 ("Makefile: Fix for
'make distcheck'") added it in the wrong spot in an attempt to reduce
differences between tarballs generated by 'make tarball' and 'make
dist'.
While being at it, drop stale xtables_config_main() prototype from
xtables-multi.h.

Subject: [PATCH] Proper fix for "unknown argument" error message
While commit 1b8210f848631 kind of fixed the corner-case of invalid
short-options packed with others, it broke error reporting for
long-options. Revert it and deploy a proper solution:
When passing an invalid short-option, e.g. 'iptables -vaL', getopt_long
sets the variable 'optopt' to the invalid character's value. Use it for
reporting instead of optind if set.
To distinguish between invalid options and missing option arguments,
ebtables-translate optstring needs adjustment.
Fixes: 1b8210f848631 ("ebtables: Fix error message for invalid parameters")

Subject: [PATCH] ebtables: Refuse unselected targets' options
Unlike legacy, ebtables-nft would allow e.g.:
| -t nat -A PREROUTING --to-dst fe:ed:00:00:ba:be
While the result is correct, it may mislead users into believing
multiple targets are possible per rule. Better follow legacy's behaviour
and reject target options unless they have been "enabled" by a previous
'-j' option.
To achieve this, one needs to distinguish targets from watchers also
attached to 'xtables_targets' and otherwise behaving like regular
matches. Introduce XTABLES_EXT_WATCHER to mark the two.
The above works already, but error messages are misleading when using
the now unsupported syntax since target options have been merged
already. Solve this by not pre-loading the targets at all, code will
just fall back to loading ad '-j' parsing time as iptables does.
Note how this also fixes for 'counter' statement being in wrong position
of ebtables-translate output.
Fixes: fe97f60e5d2a9 ("ebtables-compat: add watchers support")

Subject: [PATCH] extensions: libebt_ip: Translation has to match on ether type
On one hand, nft refuses th expression in bridge family if layer3
protocol has not been assured by a previous match. On the other, ebt_ip
kernel module will only match on IPv4 packets, so there might be a
functional change in the translation versus the original.
Instead of just always emitting an 'ether type' match, decide whether
it's actually needed - explicit "ip <something>" payload matches (or
icmp ones) cause implicit creation of a match on IPv4 by nft.

Subject: [PATCH] nft-restore: Fix for deletion of new, referenced rule
Combining multiple corner-cases here:
* Insert a rule before another new one which is not the first. Triggers
NFTNL_RULE_ID assignment of the latter.
* Delete the referenced new rule in the same batch again. Causes
overwriting of the previously assigned RULE_ID.
Consequently, iptables-nft-restore fails during *insert*, because the
reference is dangling.

Subject: [PATCH] ip6tables: Fix checking existence of rule
Pass the proper entry size when creating a match mask for checking the
existence of a rule. Failing to do so causes wrong results.

Subject: [PATCH] xshared: Fix parsing of option arguments in same word
When merging commandline parsers, a decision between 'argv[optind - 1]'
and 'optarg' had to be made in some spots. While the implementation of
check_inverse() required the former, use of the latter allows for the
common syntax of '--opt=arg' or even '-oarg' as 'optarg' will point at
the suffix while 'argv[optind - 1]' will just point at the following
option.
Fix the mess by making check_inverse() update optarg pointer if needed
so calling code may refer to and always correct 'optarg'.
Fixes: 0af80a91b0a98 ("nft: Merge xtables-arp-standalone.c into xtables-standalone.c")
Closes: https://bugzilla.netfilter.org/show_bug.cgi?id=1677
