From 6d085b22a8b5165406b5727ccf21a91ac5b97136 Mon Sep 17 00:00:00 2001 From: Pablo Neira Ayuso Date: Sat, 20 Feb 2021 16:18:03 +0100 Subject: table: support for the table owner flag Add new flag to allow userspace process to own tables: Tables that have an owner can only be updated/destroyed by the owner. The table is destroyed either if the owner process calls nft_ctx_free() or owner process is terminated (implicit table release). The ruleset listing includes the program name that owns the table: nft> list ruleset table ip x { # progname nft flags owner chain y { type filter hook input priority filter; policy accept; counter packets 1 bytes 309 } } Original code to pretty print the netlink portID to program name has been extracted from the conntrack userspace utility.
