From 68aeb21ef0e183ff3675fb82e22573e959505f95 Mon Sep 17 00:00:00 2001 From: Kuniyuki Iwashima Date: Wed, 11 Mar 2026 05:20:01 +0000 Subject: udp: Don't pass udptable to IPv4 socket lookup functions. Since UDP and UDP-Lite had dedicated socket hash tables for each, we have had to pass the pointer down to many socket lookup functions. UDP-Lite gone, and we do not need to do that. Let's fetch net->ipv4.udp_table only where needed in IPv4 stack: __udp4_lib_lookup(), __udp4_lib_mcast_deliver(), and udp_diag_dump(). Some functions are renamed as the wrapper functions are no longer needed. __udp4_lib_err() -> udp_err() __udp_diag_destroy() -> udp_diag_destroy() udp_dump_one() -> udp_diag_dump_one() udp_dump() -> udp_diag_dump() Signed-off-by: Kuniyuki Iwashima Reviewed-by: Willem de Bruijn Link: https://patch.msgid.link/20260311052020.1213705-15-kuniyu@google.com Signed-off-by: Jakub Kicinski --- include/net/udp.h | 5 ++--- 1 file changed, 2 insertions(+), 3 deletions(-) (limited to 'include') diff --git a/include/net/udp.h b/include/net/udp.h index adec74531ee1..8262e2b215b4 100644 --- a/include/net/udp.h +++ b/include/net/udp.h @@ -437,9 +437,8 @@ int udp_lib_setsockopt(struct sock *sk, int level, int optname, struct sock *udp4_lib_lookup(const struct net *net, __be32 saddr, __be16 sport, __be32 daddr, __be16 dport, int dif); struct sock *__udp4_lib_lookup(const struct net *net, __be32 saddr, - __be16 sport, - __be32 daddr, __be16 dport, int dif, int sdif, - struct udp_table *tbl, struct sk_buff *skb); + __be16 sport, __be32 daddr, __be16 dport, + int dif, int sdif, struct sk_buff *skb); struct sock *udp4_lib_lookup_skb(const struct sk_buff *skb, __be16 sport, __be16 dport); struct sock *udp6_lib_lookup(const struct net *net, -- cgit v1.2.3
