Combine parse_target() and command_jump() implementations
Merge these two functions from xtables, iptables, ip6tables and arptables. Both functions were basically identical in the first three, only the last one required a bit more attention. To eliminate access to 'invflags' in variant-specific location, move the call to set_option() into callers. This is actually consistent with parsing of other options in them. As with command_match(), use xt_params instead of the different *_globals objects to refer to 'opts' and 'orig_opts'. It was necessary to rename parse_target() as it otherwise clashes with a static function of same name in libxt_SET. In arptables, the maximum allowed target name is a bit larger, so introduce xtables_globals.target_maxnamelen defining the value. It is used in the shared xt_parse_target() implementation. Implementation of command_jump() in arptables diverted from the others for no obvious reason. The call to parse_target() was done outside of it and a pointer to cs->arp was passed but not used inside. Signed-off-by: Phil Sutter <> Signed-off-by: Florian Westphal <>
