[PATCH net-next v2 0/2] bridge: report an oversized IFLA_AF_SPEC nest instead of truncating

[Artem Lytkin <iprintercanon@gmail.com>]

v1 clamped the VLAN lists to keep the nest under the u16 nla_len.
Nikolay asked for an explicit error for both RTM_GETLINK and
notifications, with the extack set by the bridge itself. So patch 1
plumbs extack through ndo_bridge_getlink() and patch 2 returns -E2BIG
and points userspace at RTM_GETVLAN.

v1: https://lore.kernel.org/netdev/20260906224246.21719-1-iprintercanon@gmail.com/


Artem Lytkin (2):
  rtnetlink: pass extack to ndo_bridge_getlink()
  net: bridge: fail link info that does not fit the IFLA_AF_SPEC nest
