[PATCH v3 net-next 00/12] ipv4: fib: Convert RTM_NEWROUTE and RTM_DELROUTE to per-netns RTNL.

[Kuniyuki Iwashima <kuniyu@amazon.com>]

Patch 1 is misc cleanup.
Patch 2 ~ 8 converts two fib_info hash tables to per-netns.
Patch 9 ~ 12 converts rtnl_lock() to rtnl_net_lcok().


Changes:
  v3:
    * Add Eric's and David's tags
    * Patch 2
      * Use kvcalloc() instead of kvmalloc_array(, __GFP_ZERO)

  v2: https://lore.kernel.org/netdev/20250226192556.21633-1-kuniyu@amazon.com/
    * Add Eric's tag except for patch 3 (due to a minor change for exit_batch())
    * Patch 3
      * Fix memleak by calling fib4_semantics_exit() properly
      * Move fib4_semantics_exit() to fib_net_exit_batch()

  v1: https://lore.kernel.org/netdev/20250225182250.74650-1-kuniyu@amazon.com/


Kuniyuki Iwashima (12):
  ipv4: fib: Use cached net in fib_inetaddr_event().
  ipv4: fib: Allocate fib_info_hash[] and fib_info_laddrhash[] by
    kvcalloc().
  ipv4: fib: Allocate fib_info_hash[] during netns initialisation.
  ipv4: fib: Make fib_info_hashfn() return struct hlist_head.
  ipv4: fib: Remove fib_info_laddrhash pointer.
  ipv4: fib: Remove fib_info_hash_size.
  ipv4: fib: Add fib_info_hash_grow().
  ipv4: fib: Namespacify fib_info hash tables.
  ipv4: fib: Hold rtnl_net_lock() for ip_fib_net_exit().
  ipv4: fib: Hold rtnl_net_lock() in ip_rt_ioctl().
  ipv4: fib: Move fib_valid_key_len() to rtm_to_fib_config().
  ipv4: fib: Convert RTM_NEWROUTE and RTM_DELROUTE to per-netns RTNL.
