Changes since v3: - Rebase onto current master. - Whitespace fixup in patch 7. Changes since v2: - Rebased onto current master branch. With cache levels being upstream, no dependencies on unfinished work remains. - Integrate sets caching into cache level infrastructure. - Fixed temporary build breakage within series. - Larger review of last patch containing the actual among match extension. Changes since v1: - Rebased onto my performance improvements patch series. - Aligned set caching routines with changes in above series. - Fixed patch ordering so builds are not broken intermittently. - Replaced magic numbers by defines or offsetof() statements. Note that I did not move any defines into libnftnl; the remaining ones are for values in sets' key_type attribute which neither libnftnl nor kernel care about. Setting that is merely for compatibility with nft tool. This series ultimately adds among match support to ebtables-nft. The implementation merely shares the user interface with legacy one, internally the code is distinct: libebt_among.c does not make use of the wormhash data structure but a much simpler one for "temporary" storage of data until being converted into an anonymous set and associated lookup expression. Patches 1 to 5 implement required changes and are rather boring by themselves: When converting an nftnl rule to iptables command state, cache access is required (to lookup set references). Patch 6 simplifies things a bit with the above in place. Patches 7 to 11 implement anonymous set support. Patch 12 then adds the actual among match implementation for ebtables-nft.
