nft-cache: Support partial rule cache per chain
Accept an additional chain name pointer in __nft_build_cache() and pass it along to fetch only that specific chain and its rules. Enhance nft_build_cache() to take an optional nftnl_chain pointer to fetch rules for. Enhance nft_chain_list_get() to take an optional chain name. If cache level doesn't include chains already, it will fetch only the specified chain from kernel (if existing) and add that to table's chain list which is returned. This keeps operations for all chains of a table or a specific one within the same code path in nft.c. Signed-off-by: Phil Sutter <> Acked-by: Pablo Neira Ayuso <>
