Re: [PATCH net-next 1/3] netlink: specs: fou: add af to the shared attribute list

Le 04/09/2026 à 21:14, Jakub Kicinski a écrit :

parse_nl_config() is the only place the address family is chosen: it
defaults cfg->udp_config.family to AF_INET and only switches to
AF_INET6 when FOU_ATTR_AF is present. The &all_attrs anchor - the add
request, and the get do and dump reply - does not list af, so a ynl
generated client has no fou_add_req_set_af() and can never create an
IPv6 FOU port; the local-v6 / peer-v6 attributes it does list are read
by nothing. On the reply side fou_fill_info() puts FOU_ATTR_AF
unconditionally, and struct fou_get_rsp has no member for it.

kernel-policy is global, so fou_nl_ops[] carries no per-op attribute
list and af is already in fou_nl_policy through &select_attrs - only
the user space codegen and the rendered docs change, ynl-regen.sh
produces no diff.
