xtables-restore: Minimize caching when flushing
Unless --noflush was given, xtables-restore merely needs the list of tables to decide whether to delete it or not. Introduce nft_fake_cache() function which populates table list, initializes chain lists (so nft_chain_list_get() returns an empty list instead of NULL) and sets 'have_cache' to turn any later calls to nft_build_cache() into nops. If --noflush was given, call nft_build_cache() just once instead of for each table line in input. Signed-off-by: Phil Sutter <> Acked-by: Florian Westphal <>
