2023-12-08drm/crtc: Fix uninit-value bug in drm_mode_setcrtcZiqi Zhao
The connector_set contains uninitialized values when allocated with kmalloc_array. However, in the "out" branch, the logic assumes that any element in connector_set would be equal to NULL if failed to initialize, which causes the bug reported by Syzbot. The fix is to use an extra variable to keep track of how many connectors are initialized indeed, and use that variable to decrease any refcounts in the "out" branch.

2023-12-07ACPI: utils: Fix error path in acpi_evaluate_reference()Rafael J. Wysocki
If a pointer to an uninitialized struct acpi_handle_list is passed to acpi_evaluate_reference() and it decides to bail out early, either because acpi_evaluate_object() fails, or because it produces invalid data, the handles pointer from the struct acpi_handle_list will be passed to kfree() and if it is not NULL, the kernel will crash on an attempt to free unallocated memory. Address this by moving the "end" label in acpi_evaluate_reference() to the end of the function, which is sufficient, because no cleanup is needed in that case.

2023-12-07md: split MD_RECOVERY_NEEDED out of mddev_resumeYu Kuai
New mddev_resume() calls are added to synchronize IO with array reconfiguration, however, this introduces a performance regression while adding it in md_start_sync(): 1) someone sets MD_RECOVERY_NEEDED first; 2) daemon thread grabs reconfig_mutex, then clears MD_RECOVERY_NEEDED and queues a new sync work; 3) daemon thread releases reconfig_mutex; 4) in md_start_sync a) check that there are spares that can be added/removed, then suspend the array; b) remove_and_add_spares may not be called, or called without really add/remove spares; c) resume the array, then set MD_RECOVERY_NEEDED again! Loop between 2 - 4, then mddev_suspend() will be called quite often, for consequence, normal IO will be quite slow. Fix this problem by don't set MD_RECOVERY_NEEDED again in md_start_sync(), hence the loop will be broken.

2023-12-07drm: Fix FD ownership check in drm_master_check_perm()Lingkai Dong
The DRM subsystem keeps a record of the owner of a DRM device file descriptor using thread group ID (TGID) instead of process ID (PID), to ensures all threads within the same userspace process are considered the owner. However, the DRM master ownership check compares the current thread's PID against the record, so the thread is incorrectly considered to be not the FD owner if the PID is not equal to the TGID. This causes DRM ioctls to be denied master privileges, even if the same thread that opened the FD performs an ioctl. Fix this by checking TGID.

The commit 89ff3dfac604 ("usb: gadget: f_hid: fix f_hidg lifetime vs cdev") has introduced a bug that leads to hid device corruption after the replug operation. Reverse device managed memory allocation for the report descriptor to fix the issue. Tested: This change was tested on the AMD EthanolX CRB server with the BMC based on the OpenBMC distribution. The BMC provides KVM functionality via the USB gadget device: - before: KVM page refresh results in a broken USB device, - after: KVM page refresh works without any issues.

2023-12-06mm/memory_hotplug: add missing mem_hotplug_lockSumanth Korikkar
From Documentation/core-api/memory-hotplug.rst: When adding/removing/onlining/offlining memory or adding/removing heterogeneous/device memory, we should always hold the mem_hotplug_lock in write mode to serialise memory hotplug (e.g. access to global/zone variables). mhp_(de)init_memmap_on_memory() functions can change zone stats and struct page content, but they are currently called w/o the mem_hotplug_lock. When memory block is being offlined and when kmemleak goes through each populated zone, the following theoretical race conditions could occur: CPU 0: | CPU 1: memory_offline() | -> offline_pages() | -> mem_hotplug_begin() | ... | -> mem_hotplug_done() | | kmemleak_scan() | -> get_online_mems() | ... -> mhp_deinit_memmap_on_memory() | [not protected by mem_hotplug_begin/done()]| Marks memory section as offline, | Retrieves zone_start_pfn poisons vmemmap struct pages and updates | and struct page members. the zone related data | | ... | -> put_online_mems() Fix this by ensuring mem_hotplug_lock is taken before performing mhp_init_memmap_on_memory(). Also ensure that mhp_deinit_memmap_on_memory() holds the lock. online/offline_pages() are currently only called from memory_block_online/offline(), so it is safe to move the locking there.

2023-12-06md: fix stopping sync threadYu Kuai
Currently sync thread is stopped from multiple contex: - idle_sync_thread - frozen_sync_thread - __md_stop_writes - md_set_readonly - do_md_stop And there are some problems: 1) sync_work is flushed while reconfig_mutex is grabbed, this can deadlock because the work function will grab reconfig_mutex as well. 2) md_reap_sync_thread() can't be called directly while md_do_sync() is not finished yet, for example, commit 130443d60b1b ("md: refactor idle/frozen_sync_thread() to fix deadlock"). 3) If MD_RECOVERY_RUNNING is not set, there is no need to stop sync_thread at all because sync_thread must not be registered. Factor out a helper stop_sync_thread(), so that above contex will behave the same. Fix 1) by flushing sync_work after reconfig_mutex is released, before waiting for sync_thread to be done; Fix 2) bt letting daemon thread to unregister sync_thread; Fix 3) by always checking MD_RECOVERY_RUNNING first.

git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into arm/fixes Arm FF-A fixes for v6.7 A bunch of fixes addressing issues around the notification support that was added this cycle. They address issue in partition IDs handling in ffa_notification_info_get(), notifications cleanup path and the size of the allocation in ffa_partitions_cleanup(). It also adds check for the notification enabled state so that the drivers registering the callbacks can be rejected if not enabled/supported. It also moves the partitions setup operation after the notification initialisation so that the driver has the correct state for notification enabled/supported before the partitions are initialised/setup. It also now allows FF-A initialisation to complete successfully even when the notification initialisation fails as it is an optional support in the specification. Initial support just allowed it only if the firmware didn't support notifications. Finally, it also adds a fix for smatch warning by declaring ffa_bus_type structure in the header. * tag 'ffa-fixes-6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux: firmware: arm_ffa: Fix ffa_notification_info_get() IDs handling firmware: arm_ffa: Fix the size of the allocation in ffa_partitions_cleanup() firmware: arm_ffa: Fix FFA notifications cleanup path firmware: arm_ffa: Add checks for the notification enabled state firmware: arm_ffa: Setup the partitions after the notification initialisation firmware: arm_ffa: Allow FF-A initialisation even when notification fails firmware: arm_ffa: Declare ffa_bus_type structure in the header Link: https://lore.kernel.org/r/20231116191603.929767-1-sudeep.holla@arm.com Signed-off-by: Arnd Bergmann <arnd@arndb.de>
