net: annotate data-races around sk->sk_{data_ready,write_space}

2026-03-12T11:09:49+00:00

[ Upstream commit 2ef2b20cf4e04ac8a6ba68493f8780776ff84300 ] skmsg (and probably other layers) are changing these pointers while other cpus might read them concurrently.

net: do not write to msg_get_inq in callee

2026-01-17T15:35:11+00:00

commit 7d11e047eda5f98514ae62507065ac961981c025 upstream. NULL pointer dereference fix. msg_get_inq is an input field from caller to callee. Don't set it in the callee, as the caller may not clear it on struct reuse. This is a kernel-internal variant of msghdr only, and the only user does reinitialize the field. So this is not critical for that reason. But it is more robust to avoid the write, and slightly simpler code. And it fixes a bug, see below. Callers set msg_get_inq to request the input queue length to be returned in msg_inq. This is equivalent to but independent from the SO_INQ request to return that same info as a cmsg (tp->recvmsg_inq). To reduce branching in the hot path the second also sets the msg_inq. That is WAI. This is a fix to commit 4d1442979e4a ("af_unix: don't post cmsg for SO_INQ unless explicitly asked for"), which fixed the inverse. Also avoid NULL pointer dereference in unix_stream_read_generic if state->msg is NULL and msg->msg_get_inq is written. A NULL state->msg can happen when splicing as of commit 2b514574f7e8 ("net: af_unix: implement splice for stream af_unix sockets"). Also collapse two branches using a bitwise or.

af_unix: don't post cmsg for SO_INQ unless explicitly asked for

2026-01-08T09:17:09+00:00

commit 4d1442979e4a53b9457ce1e373e187e1511ff688 upstream. A previous commit added SO_INQ support for AF_UNIX (SOCK_STREAM), but it posts a SCM_INQ cmsg even if just msg->msg_get_inq is set. This is incorrect, as ->msg_get_inq is just the caller asking for the remainder to be passed back in msg->msg_inq, it has nothing to do with cmsg. The original commit states that this is done to make sockets io_uring-friendly", but it's actually incorrect as io_uring doesn't use cmsg headers internally at all, and it's actively wrong as this means that cmsg's are always posted if someone does recvmsg via io_uring. Fix that up by only posting a cmsg if u->recvmsg_inq is set. Additionally, mirror how TCP handles inquiry handling in that it should only be done for a successful return. This makes the logic for the two identical. Cc: stable@vger.kernel.org Fixes: df30285b3670 ("af_unix: Introduce SO_INQ.")

af_unix: Read sk_peek_offset() again after sleeping in unix_stream_read_generic().

2025-11-19T03:19:09+00:00

Miao Wang reported a bug of SO_PEEK_OFF on AF_UNIX SOCK_STREAM socket. The unexpected behaviour is triggered when the peek offset is larger than the recv queue and the thread is unblocked by new data. Let's assume a socket which has "aaaa" in the recv queue and the peek offset is 4. First, unix_stream_read_generic() reads the offset 4 and skips the skb(s) of "aaaa" with the code below: skip = max(sk_peek_offset(sk, flags), 0); /* @skip is 4. */ do { ... while (skip >= unix_skb_len(skb)) { skip -= unix_skb_len(skb); ... skb = skb_peek_next(skb, &sk->sk_receive_queue); if (!skb) goto again; /* @skip is 0. */ } The thread jumps to the 'again' label and goes to sleep since new data has not arrived yet. Later, new data "bbbb" unblocks the thread, and the thread jumps to the 'redo:' label to restart the entire process from the first skb in the recv queue. do { ... redo: ... last = skb = skb_peek(&sk->sk_receive_queue); ... again: if (skb == NULL) { ... timeo = unix_stream_data_wait(sk, timeo, last, last_len, freezable); ... goto redo; /* @skip is 0 !! */ However, the peek offset is not reset in the path. If the buffer size is 8, recv() will return "aaaabbbb" without skipping any data, and the final offset will be 12 (the original offset 4 + peeked skbs' length 8). After sleeping in unix_stream_read_generic(), we have to fetch the peek offset again. Let's move the redo label before mutex_lock(&u->iolock).

af_unix: Initialise scc_index in unix_add_edge().

2025-11-11T12:42:33+00:00

Quang Le reported that the AF_UNIX GC could garbage-collect a receive queue of an alive in-flight socket, with a nice repro. The repro consists of three stages. 1) 1-a. Create a single cyclic reference with many sockets 1-b. close() all sockets 1-c. Trigger GC 2) 2-a. Pass sk-A to an embryo sk-B 2-b. Pass sk-X to sk-X 2-c. Trigger GC 3) 3-a. accept() the embryo sk-B 3-b. Pass sk-B to sk-C 3-c. close() the in-flight sk-A 3-d. Trigger GC As of 2-c, sk-A and sk-X are linked to unix_unvisited_vertices, and unix_walk_scc() groups them into two different SCCs: unix_sk(sk-A)->vertex->scc_index = 2 (UNIX_VERTEX_INDEX_START) unix_sk(sk-X)->vertex->scc_index = 3 Once GC completes, unix_graph_grouped is set to true. Also, unix_graph_maybe_cyclic is set to true due to sk-X's cyclic self-reference, which makes close() trigger GC. At 3-b, unix_add_edge() allocates unix_sk(sk-B)->vertex and links it to unix_unvisited_vertices. unix_update_graph() is called at 3-a. and 3-b., but neither unix_graph_grouped nor unix_graph_maybe_cyclic is changed because both sk-B's listener and sk-C are not in-flight. 3-c decrements sk-A's file refcnt to 1. Since unix_graph_grouped is true at 3-d, unix_walk_scc_fast() is finally called and iterates 3 sockets sk-A, sk-B, and sk-X: sk-A -> sk-B (-> sk-C) sk-X -> sk-X This is totally fine. All of them are not yet close()d and should be grouped into different SCCs. However, unix_vertex_dead() misjudges that sk-A and sk-B are in the same SCC and sk-A is dead. unix_sk(sk-A)->scc_index == unix_sk(sk-B)->scc_index <-- Wrong! && sk-A's file refcnt == unix_sk(sk-A)->vertex->out_degree ^-- 1 in-flight count for sk-B -> sk-A is dead !? The problem is that unix_add_edge() does not initialise scc_index. Stage 1) is used for heap spraying, making a newly allocated vertex have vertex->scc_index == 2 (UNIX_VERTEX_INDEX_START) set by unix_walk_scc() at 1-c. Let's track the max SCC index from the previous unix_walk_scc() call and assign the max + 1 to a new vertex's scc_index. This way, we can continue to avoid Tarjan's algorithm while preventing misjudgments. Fixes: ad081928a8b0 ("af_unix: Avoid Tarjan's algorithm if unnecessary.")

VFS: rename kern_path_locked() and related functions.

2025-09-23T10:37:36+00:00

kern_path_locked() is now only used to prepare for removing an object from the filesystem (and that is the only credible reason for wanting a positive locked dentry). Thus it corresponds to kern_path_create() and so should have a corresponding name. Unfortunately the name "kern_path_create" is somewhat misleading as it doesn't actually create anything. The recently added simple_start_creating() provides a better pattern I believe. The "start" can be matched with "end" to bracket the creating or removing. So this patch changes names: kern_path_locked -> start_removing_path kern_path_create -> start_creating_path user_path_create -> start_creating_user_path user_path_locked_at -> start_removing_user_path_at done_path_create -> end_creating_path and also introduces end_removing_path() which is identical to end_creating_path(). __start_removing_path (which was __kern_path_locked) is enhanced to call mnt_want_write() for consistency with the start_creating_path().

net: replace use of system_unbound_wq with system_dfl_wq

2025-09-23T00:40:30+00:00

Currently if a user enqueue a work item using schedule_delayed_work() the used wq is "system_wq" (per-cpu wq) while queue_delayed_work() use WORK_CPU_UNBOUND (used when a cpu is not specified). The same applies to schedule_work() that is using system_wq and queue_work(), that makes use again of WORK_CPU_UNBOUND. This lack of consistentcy cannot be addressed without refactoring the API. system_unbound_wq should be the default workqueue so as not to enforce locality constraints for random work whenever it's not required. Adding system_dfl_wq to encourage its use when unbound work should be used. The old system_unbound_wq will be kept for a few release cycles.
