Merge branch 'ipv4-handle-nexthop-group-shrink-races'
Daehyeon Ko says:
====================
ipv4: handle nexthop group shrink races
fib_info_num_path() and fib_info_nhc() can observe different RCU
generations of a replaceable nexthop group. An indexed consumer can
therefore accept an index from a larger group and receive NULL after a
concurrent shrink.
Patch 1 is unchanged from v1. Patch 2 addresses the analogous
fib_dump_info_fnhe() race Ido identified. Auditing the remaining
accessor pairs found the same issue in the RCU-only hardware-flag
notification path, fixed by patch 3. Separate patches retain the
correct Fixes tag for each concurrency boundary.
