fou: Don't allow 0 for FOU_ATTR_IPPROTO.

2026-01-30T09:27:33+00:00

[ Upstream commit 7a9bc9e3f42391e4c187e099263cf7a1c4b69ff5 ] fou_udp_recv() has the same problem mentioned in the previous patch. If FOU_ATTR_IPPROTO is set to 0, skb is not freed by fou_udp_recv() nor "resubmit"-ted in ip_protocol_deliver_rcu(). Let's forbid 0 for FOU_ATTR_IPPROTO.

netlink: specs: ethtool: fix module EEPROM input/output arguments

2025-08-15T10:09:02+00:00

[ Upstream commit 01051012887329ea78eaca19b1d2eac4c9f601b5 ] Module (SFP) eeprom GET has a lot of input params, they are all mistakenly listed as output in the spec. Looks like kernel doesn't output them at all. Correct what are the inputs and what the outputs.

netlink: specs: rt-link: adjust mctp attribute naming

2025-04-25T08:45:43+00:00

[ Upstream commit beb3c5ad8829b52057f48a776a9d9558b98c157f ] MCTP attribute naming is inconsistent. In C we have: IFLA_MCTP_NET, IFLA_MCTP_PHYS_BINDING, ^^^^ but in YAML: - mctp-net - phys-binding ^ no "mctp" It's unclear whether the "mctp" part of the name is supposed to be a prefix or part of attribute name. Make it a prefix, seems cleaner, even tho technically phys-binding was added later.

netlink: specs: rt-link: add an attr layer around alt-ifname

[ Upstream commit acf4da17deada7f8b120e051aa6c9cac40dbd83b ] alt-ifname attr is directly placed in requests (as an alternative to ifname) but in responses its wrapped up in IFLA_PROP_LIST and only there is may be multi-attr.
