This series refactors code around bhash2 and remove some bhash2-specific fields; sock.sk_bind2_node, and inet_timewait_sock.tw_bind2_node. patch 1 : optimise bind() for non-wildcard v4-mapped-v6 address patch 2 - 4 : optimise bind() conflict tests patch 5 - 12 : Link bhash2 to bhash and unlink sk from bhash2 to remove sk_bind2_node The patch 8 will trigger a false-positive error by checkpatch. v2: resend of https://lore.kernel.org/netdev/20231213082029.35149-1-kuniyu@amazon.com/ * Rebase on latest net-next * Patch 11 * Add change in inet_diag_dump_icsk() for recent bhash dump patch v1: https://lore.kernel.org/netdev/20231023190255.39190-1-kuniyu@amazon.com/ Kuniyuki Iwashima (12): tcp: Use bhash2 for v4-mapped-v6 non-wildcard address. tcp: Rearrange tests in inet_bind2_bucket_(addr_match|match_addr_any)(). tcp: Save v4 address as v4-mapped-v6 in inet_bind2_bucket.v6_rcv_saddr. tcp: Save address type in inet_bind2_bucket. tcp: Rename tb in inet_bind2_bucket_(init|create)(). tcp: Link bhash2 to bhash. tcp: Rearrange tests in inet_csk_bind_conflict(). tcp: Iterate tb->bhash2 in inet_csk_bind_conflict(). tcp: Check hlist_empty(&tb->bhash2) instead of hlist_empty(&tb->owners). tcp: Unlink sk from bhash. tcp: Link sk and twsk to tb2->owners using skc_bind_node. tcp: Remove dead code and fields for bhash2. include/net/inet_hashtables.h | 21 +++---- include/net/inet_timewait_sock.h | 4 -- include/net/ipv6.h | 5 -- include/net/sock.h | 14 ----- net/ipv4/inet_connection_sock.c | 73 +++++++++++------------- net/ipv4/inet_diag.c | 2 +- net/ipv4/inet_hashtables.c | 98 +++++++++++++++----------------- net/ipv4/inet_timewait_sock.c | 21 +------ 8 files changed, 92 insertions(+), 146 deletions(-) -- 2.30.2
