[PATCH v4 net 0/2] ipv6: Fix two GC issues with permanent routes.

[Kuniyuki Iwashima <kuniyu@google.com>]

Patch 1 fixes the unbounded growth of tb6_gc_hlist due to
permanent routes whose exception routes have all expired.

Patch 2 fixes an issue where exception routes tied to
permanent routes are not properly aged.


Changes:
  v4:
    Patch 2: s/,/;/ for fib6_gc_args initialisation

  v3: https://lore.kernel.org/netdev/20260309180804.3471287-1-kuniyu@google.com/
    Patch 2: Use IS_ENABLED()

  v2: https://lore.kernel.org/netdev/20260308032304.1841198-1-kuniyu@google.com/
    Patch 2: Fix build failure when CONFIG_IPV6=n (no net->ipv6 definition)

  v1: https://lore.kernel.org/netdev/20260307024709.718395-1-kuniyu@google.com/


Kuniyuki Iwashima (2):
  ipv6: Remove permanent routes from tb6_gc_hlist when all exceptions
    expire.
  ipv6: Don't remove permanent routes with exceptions from tb6_gc_hlist.
