One of the many pain points of xtables design is the assumption of 'used only by sysadmin'. This has not been true for a very long time, so by now iptables has this userspace lock (yes, its fugly workaround) to serialize concurrent iptables invocations in userspace. AFAIU the translate-in-userspace design now brings back the old problem of different tools overwriting each others iptables rules. Another question -- am i correct in that each rule manipulation would incur a 'recompilation'? Or are there different mini programs chained together? One of the nftables advantages is that (since rule representation in kernel is black-box from userspace point of view) is that the kernel can announce add/delete of rules or elements from nftables sets. Any particular reason why translating iptables rather than nftables (it should be possible to monitor the nftables changes that are announced by kernel and act on those)? -- To unsubscribe from this list: send the line "unsubscribe netfilter-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
