8 daysdrm/xe: Extend WA 14018094691 to BMGDaniele Ceraolo Spurio
This WA is applicable to BMG as well. Note that this is a GSC WA and we don't load the GSC on BMG, so extending the WA to BMG won't do anything right now. However, it helps future-proof the driver so that if we ever turn the GSC on we won't have to remember to extend this WA. v2: don't use VERSION_RANGE from 2001 to 2004 (Matt) Signed-off-by: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Cc: Matt Roper <matthew.d.roper@intel.com> Reviewed-by: Matt Roper <matthew.d.roper@intel.com> Link: https://lore.kernel.org/r/20250613231128.1261815-2-daniele.ceraolospurio@intel.com (cherry picked from commit 1a5ce0c5b95b0624ebd44f574b98003a466973be) Signed-off-by: Lucas De Marchi <lucas.demarchi@intel.com>

https://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into arm/fixes Arm FF-A fixes for v6.16 Couple of fixes to address: 1. The safety and memory issues in the FF-A notification callback handler: The fixes replaces a mutex with an rwlock to prevent sleeping in atomic context, resolving kernel warnings. Memory allocation is moved outside the lock to support this transition safely. Additionally, a memory leak in the notifier unregistration path is fixed by properly freeing the callback node. 2. The missing entry in struct ffa_indirect_msg_hdr: The fix adds the missing 32 bit reserved entry in the structure as required by the FF-A specification. * tag 'ffa-fixes-6.16' of https://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux: firmware: arm_ffa: Fix the missing entry in struct ffa_indirect_msg_hdr firmware: arm_ffa: Replace mutex with rwlock to avoid sleep in atomic context firmware: arm_ffa: Move memory allocation outside the mutex locking firmware: arm_ffa: Fix memory leak by freeing notifier callback node Link: https://lore.kernel.org/r/20250609105207.1185570-1-sudeep.holla@arm.com Signed-off-by: Arnd Bergmann <arnd@arndb.de>
8 daysregulator: gpio: Fix the out-of-bounds access to drvdata::gpiodsManivannan Sadhasivam
drvdata::gpiods is supposed to hold an array of 'gpio_desc' pointers. But the memory is allocated for only one pointer. This will lead to out-of-bounds access later in the code if 'config::ngpios' is > 1. So fix the code to allocate enough memory to hold 'config::ngpios' of GPIO descriptors. While at it, also move the check for memory allocation failure to be below the allocation to make it more readable.

8 daysnet: ngbe: specify IRQ vector when the number of VFs is 7Jiawen Wu
For NGBE devices, the queue number is limited to be 1 when SRIOV is enabled. In this case, IRQ vector[0] is used for MISC and vector[1] is used for queue, based on the previous patches. But for the hardware design, the IRQ vector[1] must be allocated for use by the VF[6] when the number of VFs is 7. So the IRQ vector[0] should be shared for PF MISC and QUEUE interrupts. +-----------+----------------------+ | Vector | Assigned To | +-----------+----------------------+ | Vector 0 | PF MISC and QUEUE | | Vector 1 | VF 6 | | Vector 2 | VF 5 | | Vector 3 | VF 4 | | Vector 4 | VF 3 | | Vector 5 | VF 2 | | Vector 6 | VF 1 | | Vector 7 | VF 0 | +-----------+----------------------+ Minimize code modifications, only adjust the IRQ vector number for this case.

8 daysnet: wangxun: revert the adjustment of the IRQ vector sequenceJiawen Wu
Due to hardware limitations of NGBE, queue IRQs can only be requested on vector 0 to 7. When the number of queues is set to the maximum 8, the PCI IRQ vectors are allocated from 0 to 8. The vector 0 is used by MISC interrupt, and althrough the vector 8 is used by queue interrupt, it is unable to receive packets. This will cause some packets to be dropped when RSS is enabled and they are assigned to queue 8. So revert the adjustment of the MISC IRQ location, to make it be the last one in IRQ vectors.

8 daysvirtio_net: Enforce minimum TX ring size for reliabilityLaurent Vivier
The `tx_may_stop()` logic stops TX queues if free descriptors (`sq->vq->num_free`) fall below the threshold of (`MAX_SKB_FRAGS` + 2). If the total ring size (`ring_num`) is not strictly greater than this value, queues can become persistently stopped or stop after minimal use, severely degrading performance. A single sk_buff transmission typically requires descriptors for: - The virtio_net_hdr (1 descriptor) - The sk_buff's linear data (head) (1 descriptor) - Paged fragments (up to MAX_SKB_FRAGS descriptors) This patch enforces that the TX ring size ('ring_num') must be strictly greater than (MAX_SKB_FRAGS + 2). This ensures that the ring is always large enough to hold at least one maximally-fragmented packet plus at least one additional slot.

8 daysvirtio_ring: Fix error reporting in virtqueue_resizeLaurent Vivier
The virtqueue_resize() function was not correctly propagating error codes from its internal resize helper functions, specifically virtqueue_resize_packet() and virtqueue_resize_split(). If these helpers returned an error, but the subsequent call to virtqueue_enable_after_reset() succeeded, the original error from the resize operation would be masked. Consequently, virtqueue_resize() could incorrectly report success to its caller despite an underlying resize failure. This change restores the original code behavior: if (vdev->config->enable_vq_after_reset(_vq)) return -EBUSY; return err; Fix: commit ad48d53b5b3f ("virtio_ring: separate the logic of reset/enable from virtqueue_resize") Cc: xuanzhuo@linux.alibaba.com Signed-off-by: Laurent Vivier <lvivier@redhat.com> Acked-by: Jason Wang <jasowang@redhat.com> Link: https://patch.msgid.link/20250521092236.661410-2-lvivier@redhat.com Tested-by: Lei Yang <leiyang@redhat.com> Acked-by: Michael S.

8 daysHID: appletb-kbd: fix slab use-after-free bug in appletb_kbd_probeQasim Ijaz
In probe appletb_kbd_probe() a "struct appletb_kbd *kbd" is allocated via devm_kzalloc() to store touch bar keyboard related data. Later on if backlight_device_get_by_name() finds a backlight device with name "appletb_backlight" a timer (kbd->inactivity_timer) is setup with appletb_inactivity_timer() and the timer is armed to run after appletb_tb_dim_timeout (60) seconds. A use-after-free is triggered when failure occurs after the timer is armed. This ultimately means probe failure occurs and as a result the "struct appletb_kbd *kbd" which is device managed memory is freed. After 60 seconds the timer will have expired and __run_timers will attempt to access the timer (kbd->inactivity_timer) however the kdb structure has been freed causing a use-after free.

8 daysvirtio-net: xsk: rx: fix the frame's length checkBui Quang Minh
When calling buf_to_xdp, the len argument is the frame data's length without virtio header's length (vi->hdr_len). We check that len with xsk_pool_get_rx_frame_size() + vi->hdr_len to ensure the provided len does not larger than the allocated chunk size. The additional vi->hdr_len is because in virtnet_add_recvbuf_xsk, we use part of XDP_PACKET_HEADROOM for virtio header and ask the vhost to start placing data from hard_start + XDP_PACKET_HEADROOM - vi->hdr_len not hard_start + XDP_PACKET_HEADROOM But the first buffer has virtio_header, so the maximum frame's length in the first buffer can only be xsk_pool_get_rx_frame_size() not xsk_pool_get_rx_frame_size() + vi->hdr_len like in the current check. This commit adds an additional argument to buf_to_xdp differentiate between the first buffer and other ones to correctly calculate the maximum frame's length.

8 daysHID: appletb-kbd: fix memory corruption of input_handler_listQasim Ijaz
In appletb_kbd_probe an input handler is initialised and then registered with input core through input_register_handler(). When this happens input core will add the input handler (specifically its node) to the global input_handler_list. The input_handler_list is central to the functionality of input core and is traversed in various places in input core. An example of this is when a new input device is plugged in and gets registered with input core. The input_handler in probe is allocated as device managed memory. If a probe failure occurs after input_register_handler() the input_handler memory is freed, yet it will remain in the input_handler_list. This effectively means the input_handler_list contains a dangling pointer to data belonging to a freed input handler. This causes an issue when any other input device is plugged in - in my case I had an old PixArt HP USB optical mouse and I decided to plug it in after a failure occurred after input_register_handler(). This lead to the registration of this input device via input_register_device which involves traversing over every handler in the corrupted input_handler_list and calling input_attach_handler(), giving each handler a chance to bind to newly registered device. The core of this bug is a UAF which causes memory corruption of input_handler_list and to fix it we must ensure the input handler is unregistered from input core, this is done through input_unregister_handler().

9 daysdrm/gem: Acquire references on GEM handles for framebuffersThomas Zimmermann
A GEM handle can be released while the GEM buffer object is attached to a DRM framebuffer. This leads to the release of the dma-buf backing the buffer object, if any.

I226 devices advertise support for the PCI-E link L1.2 substate. However, due to a hardware limitation, the exit latency from this low-power state is longer than the packet buffer can tolerate under high traffic conditions. This can lead to packet loss and degraded performance. To mitigate this, disable the L1.2 substate. The increased power draw between L1.1 and L1.2 is insignificant.

10 daysbrd: fix sleeping function called from invalid context in brd_insert_page()Yu Kuai
__xa_cmpxchg() is called with rcu_read_lock(), and it will allocate memory if necessary. Fix the problem by moving rcu_read_lock() after __xa_cmpxchg(), meanwhile, it still should be held before xa_unlock(), prevent returned page to be freed by concurrent discard.

10 daysublk: don't queue request if the associated uring_cmd is canceledMing Lei
Commit 524346e9d79f ("ublk: build batch from IOs in same io_ring_ctx and io task") need to dereference `io->cmd` for checking if the IO can be added to current batch, see ublk_belong_to_same_batch() and io_uring_cmd_ctx_handle(). However, `io->cmd` may become invalid after the uring_cmd is canceled. Fixes it by only allowing to queue this IO in case that ublk_prep_req() returns `BLK_STS_OK`, when 'io->cmd' is guaranteed to be valid.
