The commit bc543af ("ebtables-compat: fix segfault in rules w/o target") doesn't handle all possible cases of target printing, and ACCEPT is left behind. BTW, the logic of target (-j XXX) printing is a bit weird. This patch simplifies it. I assume: * cs->jumpto is only filled by nft_immediate. * cs->target is only filled by nft_target. So we end with these cases: * nft_immediate contains a 'standard' target (ACCEPT, DROP, CONTINUE, RETURN, chain) Then cs->jumpto contains the target already. We have the rule. * No standard target. If nft_target contains a target, try to load it. * Neither nft_target nor nft_immediate exist. Then, assume CONTINUE. The printing path is then straight forward: either cs.jumpto or cs.target contains the target. As there isn't support for target extensions yet, there is no way to test the nft_target (cs.target) path.
