This update allows listing default firewalld ruleset on Fedora 40 via tools/net/ynl/cli.py --spec \ Documentation/netlink/specs/nftables.yaml --dump getrule Default ruleset uses fib, reject and objref expressions which were missing. Other missing expressions can be added later. Improve decoding while at it: - add bitwise, ct and lookup attributes - wire up the quota expression - translate raw verdict codes to a human reable name, e.g. 'code': 4294967293 becomes 'code': 'jump'. v2: forgot fib addrtype in enum list (Donald Hunter) Reviewed-by: Donald Hunter <donald.hunter@gmail.com> Signed-off-by: Florian Westphal <fw@strlen.de> --- Documentation/netlink/specs/nftables.yaml | 254 +++++++++++++++++++++- 1 file changed, 250 insertions(+), 4 deletions(-)
