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: v2: * Add Eric's tags 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 kvmalloc_array(). 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. include/net/ip_fib.h | 2 + include/net/netns/ipv4.h | 3 + net/ipv4/fib_frontend.c | 74 ++++++++++---- net/ipv4/fib_semantics.c | 207 +++++++++++++++++++-------------------- net/ipv4/fib_trie.c | 22 ----- 5 files changed, 160 insertions(+), 148 deletions(-)
