Subject: [PATCH net 0/8] ynl: avoid leaks in attr override and spec fixes for C

The C rt-link work revealed more problems in existing codegen
and classic netlink specs.

Patches 1 - 4 fix issues with the codegen. Patches 1 and 2 are
pre-requisites for patch 3. Patch 3 fixes leaking memory if user
tries to override already set attr. Patch 4 validates attrs in case
kernel sends something we don't expect.

Remaining patches fix and align the specs. Patch 5 changes nesting,
the rest are naming adjustments.

Jakub Kicinski (8):
  tools: ynl-gen: don't declare loop iterator in place
  tools: ynl-gen: move local vars after the opening bracket
  tools: ynl-gen: individually free previous values on double set
  tools: ynl-gen: make sure we validate subtype of array-nest
  netlink: specs: rt-link: add an attr layer around alt-ifname
  netlink: specs: rtnetlink: attribute naming corrections
  netlink: specs: rt-link: adjust mctp attribute naming
  netlink: specs: rt-neigh: prefix struct nfmsg members with ndm
