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/uapi/regulator/regulator.h | 86 ++++++++++++++++++++++++++++++++++++++ 1 file changed, 86 insertions(+) create mode 100644 include/uapi/regulator/regulator.h (limited to 'include/uapi/regulator') diff --git a/include/uapi/regulator/regulator.h b/include/uapi/regulator/regulator.h new file mode 100644 index 000000000..c4f2d1c19 --- /dev/null +++ b/include/uapi/regulator/regulator.h @@ -0,0 +1,86 @@ +/* SPDX-License-Identifier: GPL-2.0 WITH Linux-syscall-note */ +/* + * Regulator uapi header + * + * Author: Naresh Solanki + */ + +#ifndef _UAPI_REGULATOR_H +#define _UAPI_REGULATOR_H + +#include + +/* + * Regulator notifier events. + * + * UNDER_VOLTAGE Regulator output is under voltage. + * OVER_CURRENT Regulator output current is too high. + * REGULATION_OUT Regulator output is out of regulation. + * FAIL Regulator output has failed. + * OVER_TEMP Regulator over temp. + * FORCE_DISABLE Regulator forcibly shut down by software. + * VOLTAGE_CHANGE Regulator voltage changed. + * Data passed is old voltage cast to (void *). + * DISABLE Regulator was disabled. + * PRE_VOLTAGE_CHANGE Regulator is about to have voltage changed. + * Data passed is "struct pre_voltage_change_data" + * ABORT_VOLTAGE_CHANGE Regulator voltage change failed for some reason. + * Data passed is old voltage cast to (void *). + * PRE_DISABLE Regulator is about to be disabled + * ABORT_DISABLE Regulator disable failed for some reason + * + * NOTE: These events can be OR'ed together when passed into handler. + */ + +#define REGULATOR_EVENT_UNDER_VOLTAGE 0x01 +#define REGULATOR_EVENT_OVER_CURRENT 0x02 +#define REGULATOR_EVENT_REGULATION_OUT 0x04 +#define REGULATOR_EVENT_FAIL 0x08 +#define REGULATOR_EVENT_OVER_TEMP 0x10 +#define REGULATOR_EVENT_FORCE_DISABLE 0x20 +#define REGULATOR_EVENT_VOLTAGE_CHANGE 0x40 +#define REGULATOR_EVENT_DISABLE 0x80 +#define REGULATOR_EVENT_PRE_VOLTAGE_CHANGE 0x100 +#define REGULATOR_EVENT_ABORT_VOLTAGE_CHANGE 0x200 +#define REGULATOR_EVENT_PRE_DISABLE 0x400 +#define REGULATOR_EVENT_ABORT_DISABLE 0x800 +#define REGULATOR_EVENT_ENABLE 0x1000 +/* + * Following notifications should be emitted only if detected condition + * is such that the HW is likely to still be working but consumers should + * take a recovery action to prevent problems escalating into errors. + */ +#define REGULATOR_EVENT_UNDER_VOLTAGE_WARN 0x2000 +#define REGULATOR_EVENT_OVER_CURRENT_WARN 0x4000 +#define REGULATOR_EVENT_OVER_VOLTAGE_WARN 0x8000 +#define REGULATOR_EVENT_OVER_TEMP_WARN 0x10000 +#define REGULATOR_EVENT_WARN_MASK 0x1E000 + +struct reg_genl_event { + char reg_name[32]; + __u64 event; +}; + +/* attributes of reg_genl_family */ +enum { + REG_GENL_ATTR_UNSPEC, + REG_GENL_ATTR_EVENT, /* reg event info needed by user space */ + __REG_GENL_ATTR_MAX, +}; + +#define REG_GENL_ATTR_MAX (__REG_GENL_ATTR_MAX - 1) + +/* commands supported by the reg_genl_family */ +enum { + REG_GENL_CMD_UNSPEC, + REG_GENL_CMD_EVENT, /* kernel->user notifications for reg events */ + __REG_GENL_CMD_MAX, +}; + +#define REG_GENL_CMD_MAX (__REG_GENL_CMD_MAX - 1) + +#define REG_GENL_FAMILY_NAME "reg_event" +#define REG_GENL_VERSION 0x01 +#define REG_GENL_MCAST_GROUP_NAME "reg_mc_group" + +#endif /* _UAPI_REGULATOR_H */ -- cgit v1.3.1
