[PATCH net-next v3 0/2] bridge: report an oversized IFLA_AF_SPEC nest instead of truncating

[Artem Lytkin <iprintercanon@gmail.com>]

Patch 1 adds extack to ndo_bridge_getlink(), patch 2 returns -E2BIG
when the AF_SPEC nest, or the MST/CFM nest inside it, overflows nla_len.

v3: handle the MST and CFM nests too, use nla_nest_end_safe() (Nikolay)
v2: https://lore.kernel.org/netdev/20260912135022.1701-1-iprintercanon@gmail.com/
v1: https://lore.kernel.org/netdev/20260906224246.21719-1-iprintercanon@gmail.com/

  rtnetlink: pass extack to ndo_bridge_getlink()
  net: bridge: fail link info that does not fit in a netlink attribute
