From 9f0346dcbea363787186c94ef94dd01aaa215afa Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Sat, 5 Sep 2026 11:59:05 -0700 Subject: Merge tag 'driver-core-7.3-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/driver-core/driver-core Pull driver core fixes from Danilo Krummrich: - Fix kernfs listxattr() not returning security xattr names (e.g. SELinux labels) when the kernfs node has no allocated kernfs_iattrs - Fix silent truncation of IRQ vector indices in the Rust PCI abstractions - Don't select OF from DRIVER_PE_KUNIT_TEST; skip the test when OF is disabled instead of silently enabling extra kernel functionality - Russ Weight is retiring from kernel development; update the Firmware Loader sysfs contact to the driver-core mailing list, add a CREDITS entry for Firmware Upload, and update MAINTAINERS accordingly * tag 'driver-core-7.3-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/driver-core/driver-core: MAINTAINERS: Remove Russ Weight from Firmware Loader CREDITS: Add CREDITS entry for Firmware Upload firmware_loader: Change contact for sysfs nodes rust: pci: reject IRQ vector indices that do not fit in u32 kernfs: preserve security xattrs without allocating iattrs drivers: base: test: DRIVER_PE_KUNIT_TEST should not select OF --- include/crypto/internal/engine.h | 58 ++++++++++++++++++++++++++++++++++++++++ 1 file changed, 58 insertions(+) create mode 100644 include/crypto/internal/engine.h (limited to 'include/crypto/internal/engine.h') diff --git a/include/crypto/internal/engine.h b/include/crypto/internal/engine.h new file mode 100644 index 000000000..6a1d27880 --- /dev/null +++ b/include/crypto/internal/engine.h @@ -0,0 +1,58 @@ +/* SPDX-License-Identifier: GPL-2.0-or-later */ +/* + * Crypto engine API + * + * Copyright (c) 2016 Baolin Wang + * Copyright (c) 2023 Herbert Xu + */ +#ifndef _CRYPTO_INTERNAL_ENGINE_H +#define _CRYPTO_INTERNAL_ENGINE_H + +#include +#include +#include +#include +#include + +#define ENGINE_NAME_LEN 30 + +struct device; + +/* + * struct crypto_engine - crypto hardware engine + * @name: the engine name + * @busy: request pump is busy + * @running: the engine is on working + * @retry_support: indication that the hardware allows re-execution + * of a failed backlog request + * crypto-engine, in head position to keep order + * @rt: whether this queue is set to run as a realtime task + * @list: link with the global crypto engine list + * @queue_lock: spinlock to synchronise access to request queue + * @queue: the crypto queue of the engine + * @kworker: kthread worker struct for request pump + * @pump_requests: work struct for scheduling work to the request pump + * @priv_data: the engine private data + * @cur_req: the current request which is on processing + */ +struct crypto_engine { + char name[ENGINE_NAME_LEN]; + bool busy; + bool running; + + bool retry_support; + bool rt; + + struct list_head list; + spinlock_t queue_lock; + struct crypto_queue queue __guarded_by(&queue_lock); + struct device *dev; + + struct kthread_worker *kworker; + struct kthread_work pump_requests; + + void *priv_data; + struct crypto_async_request *cur_req; +}; + +#endif -- cgit v1.3.1
