Tue, 24 Feb 2026 19:36:09 +0100

io_uring/cmd_net: use READ_ONCE() for ->addr3 readAny SQE read should use READ_ONCE(), to ensure the result is read onceand only once. Doesn't really matter for this case, but it's better tokeep these 100% consistent and always use READ_ONCE() for the prep sideof SQE handling.Fixes: 5d24321e4c15 ("io_uring: Introduce getsockname io_uring cmd")Signed-off-by: Jens Axboe List of files: /linux/io_uring/cmd_net.c

Mon, 16 Feb 2026 11:27:18 +0100

io_uring/cmd_net: fix too strict requirement on ioctlAttempting SOCKET_URING_OP_SETSOCKOPT on an AF_NETLINK socket resultedin an -EOPNOTSUPP, as AF_NETLINK doesn't have an ioctl in its structproto, but only in struct proto_ops.Prior to the blamed commit, io_uring_cmd_sock() only had two cmd_opoperations, both requiring ioctl, thus the check was warranted.Since then, 4 new cmd_op operations have been added, none of whichdepend on ioctl. This patch moves the ioctl check, so it only appliesto the original operations.AFAICT, the ioctl requirement was unintentional, and it wasn'tvisible in the blamed patch within 3 lines of context.Cc: stable@vger.kernel.orgFixes: a5d2f99aff6b ("io_uring/cmd: Introduce SOCKET_URING_OP_GETSOCKOPT")Signed-off-by: Asbjørn Sloth Tønnesen Reviewed-by: Gabriel Krisman Bertazi Signed-off-by: Jens Axboe List of files: /linux/io_uring/cmd_net.c

Merge tag 'for-7.0/io_uring-20260206' of git://git.kernel.org/pub/scm/linux/kernel/git/axboe/linuxPull io_uring updates from Jens Axboe: - Clean up the IORING_SETUP_R_DISABLED and submitter task checking, mostly just in preparation for relaxing the locking for SINGLE_ISSUER in the future. - Improve IOPOLL by using a doubly linked list to manage completions. Previously it was singly listed, which meant that to complete request N in the chain 0..N-1 had to have completed first. With a doubly linked list we can complete whatever request completes in that order, rather than need to wait for a consecutive range to be available. This reduces latencies. - Improve the restriction setup and checking. Mostly in preparation for adding further features on top of that. Coming in a separate pull request. - Split out task_work and wait handling into separate files. These are mostly nicely abstracted already, but still remained in the io_uring.c file which is on the larger side. - Use GFP_KERNEL_ACCOUNT in a few more spots, where appropriate. - Ensure even the idle io-wq worker exits if a task no longer has any rings open. - Add support for a non-circular submission queue. By default, the SQ ring keeps moving around, even if only a few entries are used for each submission. This can be wasteful in terms of cachelines. If IORING_SETUP_SQ_REWIND is set for the ring when created, each submission will start at offset 0 instead of where we last left off doing submissions. - Various little cleanups* tag 'for-7.0/io_uring-20260206' of git://git.kernel.org/pub/scm/linux/kernel/git/axboe/linux: (30 commits) io_uring/kbuf: fix memory leak if io_buffer_add_list fails io_uring: Add SPDX id lines to remaining source files io_uring: allow io-wq workers to exit when unused io_uring/io-wq: add exit-on-idle state io_uring/net: don't continue send bundle if poll was required for retry io_uring/rsrc: use GFP_KERNEL_ACCOUNT consistently io_uring/futex: use GFP_KERNEL_ACCOUNT for futex data allocation io_uring/io-wq: handle !sysctl_hung_task_timeout_secs io_uring: fix bad indentation for setup flags if statement io_uring/rsrc: take unsigned index in io_rsrc_node_lookup() io_uring: introduce non-circular SQ io_uring: split out CQ waiting code into wait.c io_uring: split out task work code into tw.c io_uring/io-wq: don't trigger hung task for syzbot craziness io_uring: add IO_URING_EXIT_WAIT_MAX definition io_uring/sync: validate passed in offset io_uring/eventfd: remove unused ctx->evfd_last_cq_tail member io_uring/timeout: annotate data race in io_flush_timeouts() io_uring/uring_cmd: explicitly disallow cancelations for IOPOLL io_uring: fix IOPOLL with passthrough I/O ...

Merge tag 'for-6.19/io_uring-20251201' of git://git.kernel.org/pub/scm/linux/kernel/git/axboe/linuxPull io_uring updates from Jens Axboe: - Unify how task_work cancelations are detected, placing it in the task_work running state rather than needing to check the task state - Series cleaning up and moving the cancelation code to where it belongs, in cancel.c - Cleanup of waitid and futex argument handling - Add support for mixed sized SQEs. 6.18 added support for mixed sized CQEs, improving flexibility and efficiency of workloads that need big CQEs. This adds similar support for SQEs, where the occasional need for a 128b SQE doesn't necessitate having all SQEs be 128b in size - Introduce zcrx and SQ/CQ layout queries. The former returns what zcrx features are available. And both return the ring size information to help with allocation size calculation for user provided rings like IORING_SETUP_NO_MMAP and IORING_MEM_REGION_TYPE_USER - Zcrx updates for 6.19. It includes a bunch of small patches, IORING_REGISTER_ZCRX_CTRL and RQ flushing and David's work on sharing zcrx b/w multiple io_uring instances - Series cleaning up ring initializations, notable deduplicating ring size and offset calculations. It also moves most of the checking before doing any allocations, making the code simpler - Add support for getsockname and getpeername, which is mostly a trivial hookup after a bit of refactoring on the networking side - Various fixes and cleanups* tag 'for-6.19/io_uring-20251201' of git://git.kernel.org/pub/scm/linux/kernel/git/axboe/linux: (68 commits) io_uring: Introduce getsockname io_uring cmd socket: Split out a getsockname helper for io_uring socket: Unify getsockname and getpeername implementation io_uring/query: drop unused io_handle_query_entry() ctx arg io_uring/kbuf: remove obsolete buf_nr_pages and update comments io_uring/register: use correct location for io_rings_layout io_uring/zcrx: share an ifq between rings io_uring/zcrx: add io_fill_zcrx_offsets() io_uring/zcrx: export zcrx via a file io_uring/zcrx: move io_zcrx_scrub() and dependencies up io_uring/zcrx: count zcrx users io_uring/zcrx: add sync refill queue flushing io_uring/zcrx: introduce IORING_REGISTER_ZCRX_CTRL io_uring/zcrx: elide passing msg flags io_uring/zcrx: use folio_nr_pages() instead of shift operation io_uring/zcrx: convert to use netmem_desc io_uring/query: introduce rings info query io_uring/query: introduce zcrx query io_uring: move cq/sq user offset init around io_uring: pre-calculate scq layout ...

There's also a batch of new drivers added for bothSoCs and CODECs. - Added a SoundWire SCDA generic class driver, pulling in a little regmap work to support it. - A *lot* of cleaup and API improvement work from Morimoto-san. - Lots of work on the existing Cirrus, Intel, Maxim and Qualcomm drivers. - Support for Allwinner A523, Mediatek MT8189, Qualcomm QCM2290, QRB2210 and SM6115, SpacemiT K1, and TI TAS2568, TAS5802, TAS5806, TAS5815, TAS5828 and TAS5830.This also pulls in some gpiolib changes supporting shared GPIOs in thecore there so we can convert some of the ASoC drivers open codinghandling of that to the core functionality.
