* src: restore interface to index cachePablo Neira Ayuso2015-04-111-0/+147
nftables used to have a cache to speed up interface name <-> index lookup, restore it using libmnl. This reduces netlink traffic since if_nametoindex() and if_indextoname() open, send a request, receive the list of interface and close a netlink socket for each call. I think this is also good for consistency since nft -f will operate with the same index number when reloading the ruleset. The cache is populated by when nft_if_nametoindex() and nft_if_indextoname() are used for first time. Then, it it released in the output path. In the interactive mode, it is invalidated after each command. Signed-off-by: Pablo Neira Ayuso <>
