This patch adds a new command to nft: % nft list ruleset [family] Which list the entire ruleset. If no family is specified, all tables of all families are listed. Users can now make several operations at ruleset level: % nft list ruleset > ruleset.nft % nft -f ruleset.nft % nft flush ruleset Signed-off-by: Arturo Borrero Gonzalez <arturo.borrero.glez@gmail.com> --- v2: rename function to do_list_ruleset() and use list_splice_tail_init(). v3: fixed clash with static list "table_list", and double free() of a handle. src/parser.y | 4 ++++ src/rule.c | 28 ++++++++++++++++++++++++++++ 2 files changed, 32 insertions(+)
