From 3f1fe48a36b0b6722dc3fd421d93512bac138e9a Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Fri, 2 Oct 2026 12:17:24 -0700 Subject: Merge tag 'io_uring-7.3-20261002' of git://git.kernel.org/pub/scm/linux/kernel/git/axboe/linux Pull io_uring fixes from Jens Axboe: - Fix a task_work add use-after-free with SQPOLL. The sqpoll thread could pop and complete the last request while io_req_normal_work_add() was still looking at them after the mpscq push. Use the same approach as DEFER_TASKRUN to protect from that, holding an RCU read lock across the add, and have exit wait for an RCU grace period for SQPOLL rings as well. - CQE32 ring fixes: correct the free entry check for 32b CQEs, zero the big_cqe for aux CQEs, and only post the dummy skip CQE on CQE_MIXED rings - Mark the source filter table as COW when cloning bpf filters, so registering another filter on the source doesn't modify the shared table in place - Initialize the task context before running the BPF loop - Requeue zcrx multishot receives stopped by a local resource - End a TX_TIMESTAMP multishot cmd when the CQ is full (lollipopkit) * tag 'io_uring-7.3-20261002' of git://git.kernel.org/pub/scm/linux/kernel/git/axboe/linux: io_uring: fix task_work add use-after-free with SQPOLL io_uring/cmd_net: end TX_TIMESTAMP multishot when the CQ is full io_uring/zcrx: requeue multishot receives stopped by a local resource io_uring: initialize task context before running the BPF loop io_uring: zero big_cqe for aux CQEs on CQE32 rings io_uring: fix free entry check for 32b CQEs on CQE32 rings io_uring: only post the dummy skip CQE on CQE_MIXED rings io_uring/bpf_filter: mark source as COW when cloning filters --- LICENSES/exceptions/Linux-syscall-note | 25 +++++++++++++++++++++++++ 1 file changed, 25 insertions(+) create mode 100644 LICENSES/exceptions/Linux-syscall-note (limited to 'LICENSES/exceptions/Linux-syscall-note') diff --git a/LICENSES/exceptions/Linux-syscall-note b/LICENSES/exceptions/Linux-syscall-note new file mode 100644 index 000000000..9abdad71f --- /dev/null +++ b/LICENSES/exceptions/Linux-syscall-note @@ -0,0 +1,25 @@ +SPDX-Exception-Identifier: Linux-syscall-note +SPDX-URL: https://spdx.org/licenses/Linux-syscall-note.html +SPDX-Licenses: GPL-2.0, GPL-2.0+, GPL-1.0+, LGPL-2.0, LGPL-2.0+, LGPL-2.1, LGPL-2.1+, GPL-2.0-only, GPL-2.0-or-later +Usage-Guide: + This exception is used together with one of the above SPDX-Licenses + to mark user space API (uapi) header files so they can be included + into non GPL compliant user space application code. + To use this exception add it with the keyword WITH to one of the + identifiers in the SPDX-Licenses tag: + SPDX-License-Identifier: WITH Linux-syscall-note +License-Text: + + NOTE!
