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 --- include/crypto/cryptd.h | 39 +++++++++++++++++++++++++++++++++++++++ 1 file changed, 39 insertions(+) create mode 100644 include/crypto/cryptd.h (limited to 'include/crypto/cryptd.h') diff --git a/include/crypto/cryptd.h b/include/crypto/cryptd.h new file mode 100644 index 000000000..29c5878a3 --- /dev/null +++ b/include/crypto/cryptd.h @@ -0,0 +1,39 @@ +/* SPDX-License-Identifier: GPL-2.0 */ +/* + * Software async crypto daemon + * + * Added AEAD support to cryptd. + * Authors: Tadeusz Struk (tadeusz.struk@intel.com) + * Adrian Hoban + * Gabriele Paoloni + * Aidan O'Mahony (aidan.o.mahony@intel.com) + * Copyright (c) 2010, Intel Corporation. + */ + +#ifndef _CRYPTO_CRYPT_H +#define _CRYPTO_CRYPT_H + +#include + +#include + +struct cryptd_aead { + struct crypto_aead base; +}; + +static inline struct cryptd_aead *__cryptd_aead_cast( + struct crypto_aead *tfm) +{ + return (struct cryptd_aead *)tfm; +} + +struct cryptd_aead *cryptd_alloc_aead(const char *alg_name, + u32 type, u32 mask); + +struct crypto_aead *cryptd_aead_child(struct cryptd_aead *tfm); +/* Must be called without moving CPUs. */ +bool cryptd_aead_queued(struct cryptd_aead *tfm); + +void cryptd_free_aead(struct cryptd_aead *tfm); + +#endif -- cgit v1.3.1
