net: Convert proto_ops connect() callbacks to use sockaddr_unsized

2025-11-05T03:10:32Z

Update all struct proto_ops connect() callback function prototypes from "struct sockaddr *" to "struct sockaddr_unsized *" to avoid lying to the compiler about object sizes. Calls into struct proto handlers gain casts that will be removed in the struct proto conversion patch. No binary changes expected.

net: remove obsolete WARN_ON(refcount_read(&sk->sk_refcnt) == 1)

2025-10-16T00:18:38Z

sk->sk_refcnt has been converted to refcount_t in 2017. __sock_put(sk) being refcount_dec(&sk->sk_refcnt), it will complain loudly if the current refcnt is 1 (or less) in a non racy way. We can remove four WARN_ON() in favor of the generic refcount_dec() check.

net: add sk_drops_read(), sk_drops_inc() and sk_drops_reset() helpers

2025-08-28T11:14:50Z

We want to split sk->sk_drops in the future to reduce potential contention on this field. Signed-off-by: Eric Dumazet Reviewed-by: Kuniyuki Iwashima Link: https://patch.msgid.link/20250826125031.1578842-2-edumazet@google.com Signed-off-by: Paolo Abeni

net: remove sock_i_uid()

2025-06-24T00:04:03Z

Difference between sock_i_uid() and sk_uid() is that after sock_orphan(), sock_i_uid() returns GLOBAL_ROOT_UID while sk_uid() returns the last cached sk->sk_uid value. None of sock_i_uid() callers care about this. Use sk_uid() which is much faster and inlined. Note that diag/dump users are calling sock_i_ino() and can not see the full benefit yet.

net/tipc: make use of the helper macro LIST_HEAD()

list_head can be initialized automatically with LIST_HEAD() instead of calling INIT_LIST_HEAD(). Here we can simplify the code. Signed-off-by: Hongbo Li Link: https://patch.msgid.link/20240904093243.3345012-3-lihongbo22@huawei.com Signed-off-by: Jakub Kicinski

kernel-wide: fix spelling mistakes like "assocative" -> "associative"

2024-06-29T02:36:28Z

There were several instances of the string "assocat" in the kernel, which should have been spelled "associat", with the various endings of -ive, -ed, -ion, and sometimes beginnging with dis-. Add to the spelling dictionary the corrections so that future instances will be caught by checkpatch, and fix the instances found. Originally noticed by accident with a 'git grep socat'.

net: change proto and proto_ops accept type

2024-05-14T00:19:09Z

Rather than pass in flags, error pointer, and whether this is a kernel invocation or not, add a struct proto_accept_arg struct as the argument. This then holds all of these arguments, and prepares accept for being able to pass back more information. No functional changes in this patch. Acked-by: Jakub Kicinski Signed-off-by: Jens Axboe

tipc: remove redundant assignment to ret, simplify code

2024-04-13T02:07:31Z

Variable err is being assigned a zero value and it is never read afterwards in either the break path or continue path, the assignment is redundant and can be removed. With it removed, the if statement can also be simplified.
