cache: add hashtable cache for sets
This patch adds a hashtable for set lookups. This patch also splits table->sets in two: - Sets that reside in the cache are stored in the new tables->cache_set and tables->cache_set_ht. - Set that defined via command line / ruleset file reside in tables->set. Sets in the cache (already in the kernel) are not placed in the table->sets list. By keeping separated lists, sets defined via command line / ruleset file can be added to cache. Adding 10000 sets, before: # time nft -f x real 0m6,415s user 0m3,126s sys 0m3,284s After: # time nft -f x real 0m3,949s user 0m0,743s sys 0m3,205s Signed-off-by: Pablo Neira Ayuso <>
