2026-07-13drm/virtio: fix deadlock in display_info_cb by removing hotplug from dequeue ↵Ryosuke Yasuoka
worker A probe-time deadlock can occur between the dequeue worker and drm_client_register(). During probe, drm_client_register() holds clientlist_mutex and calls the fbdev hotplug callback, which triggers an atomic commit that ends up sleeping in virtio_gpu_queue_ctrl_sgs() waiting for virtqueue space. The dequeue worker that would free that space calls virtio_gpu_cmd_get_display_info_cb(), which invokes drm_kms_helper_hotplug_event() -> drm_client_dev_hotplug(), attempting to acquire the same clientlist_mutex. Since wake_up() is only called after the resp_cb loop, the probe thread is never woken and both threads deadlock. Fix this by removing the hotplug notification from virtio_gpu_cmd_get_display_info_cb(). The display data (outputs[i].info) is still updated synchronously in the callback. For the init path, drm_client_register() already fires an initial hotplug when the client is registered, which picks up the connector state updated by display_info_cb. For the runtime config_changed path, add a wait_event_timeout() in config_changed_work_func() so that display_info_cb updates the connector data before the hotplug notification is sent. Also replace drm_helper_hpd_irq_event() with drm_kms_helper_hotplug_event() since virtio-gpu never calls drm_kms_helper_poll_init() and thus drm_helper_hpd_irq_event() always returns false without doing anything.

2026-07-13x86/alternative: Drop smp_locks glueBorislav Petkov (AMD)
This was there to be able to patch out locking instructions when running a SMP kernel build on a UP CPU. The times are long gone when single-CPU x86 machines were relevant so drop that machinery and simplify the code considerably. LOCK_PREFIX needs to stay for when one wants to do a UP build for whatever reason. That'll go away when CONFIG_SMP becomes unconditional. Kill a bunch of leftover, unused prototypes while at it.

Commit 53b7c271f06b ("smb: client: restrict implied bcc[0] exemption to responses without data area") restricted the implied bcc[0] length exception to responses without a data area. However, the overlap handling in __smb2_calc_size() clears data_length, which can make an invalid response appear to have no data area and so qualify for the exception. Track data area overlap separately and reject such responses before applying the length compatibility exceptions.

2026-07-13smb/client: refresh allocation after EOF-extending fallocateHuiwen He
Before this change, xfstests generic/496 was not supported on ksmbd: generic/496 ... [not run] fallocated swap not supported here ksmbd handles SetEOF as truncate, so EOF extension alone does not allocate backing blocks. A fallocated swapfile can therefore still look sparse to swapon. Request allocation for EOF-extending fallocate ranges that can be represented by FILE_ALLOCATION_INFORMATION, and refresh the allocation state afterwards. With this change, xfstests generic/496 and generic/701 pass on ksmbd. However, Samba "strict allocate = no" now exposes the real generic/701 failure: the old pass came from inflated local i_blocks, not from server allocation. generic/213 also fails in that case because an oversized allocation request may not return ENOSPC.

2026-07-13smb/client: emulate small EOF-extending mode 0 fallocate rangesHuiwen He
When a mode 0 fallocate extends EOF from 1G to 2G + 1M, the client currently sends SetEOF for 2G + 1M. This can make fallocate return success without allocating the requested range, or allocate extra space before that range. For example, on a fresh file: xfs_io -f \ -c "falloc 0 1G" \ -c "falloc 2G 1M" \ -c "truncate 3G" test The second fallocate should allocate [2G, 2G + 1M), leaving [1G, 2G) as a hole. Before this change, the result depended on the server allocation policy. With Samba "strict allocate = no", SetEOF could return success without allocating [2G, 2G + 1M). With "strict allocate = yes": # filefrag -v test [0, 1G) allocated [1G, 2G) allocated unexpectedly [2G, 2G + 1M) allocated SMB cannot allocate that arbitrary range, so write zeroes to small EOF-extending ranges instead. Limit this to 1 MiB to bound the client-side I/O cost. With "strict allocate = no", the requested range [2G, 2G + 1M) is allocated by the writes. With "strict allocate = yes": # filefrag -v test [0, 1G) allocated [1G, 2G) hole [2G, 2G + 1M) allocated This fixes the small EOF-extending range case exercised by generic/213.

2026-07-13smb/client: reduce fallocate zero buffer allocationHuiwen He
The fallocate emulation allocates a 1 MiB zero-filled buffer even though each SMB2_write request is limited to SMB2_MAX_BUFFER_SIZE, which is 64 KiB. A high-order 1 MiB allocation is more likely to fail on a fragmented system. Allocate only the smaller of the requested range and SMB2_MAX_BUFFER_SIZE, and reuse that zero-filled buffer for every write request. Also reject a successful write that makes no progress to avoid looping indefinitely. This reduces the contiguous allocation required by fallocate emulation without changing the written data or range semantics.

2026-07-13smb/client: handle overlapping allocated ranges in fallocateHuiwen He
smb3_simple_fallocate_range() can skip holes when an allocated range returned by the server starts before the current fallocate offset. The skipped hole is not zero-filled, but fallocate still returns success. A later write to that hole may therefore fail with ENOSPC. The function queries allocated ranges so that it can preserve existing contents and write zeroes only into holes. However, the server may return a range that starts before the current fallocate offset. For example, assume the fallocate request is [100, 400) and the only allocated range returned by the server is [0, 200): Request: [100, 400) Server range: [ 0, 200) allocated Correct: [100, 200) allocated data, skip [200, 400) hole, zero-fill Current: [100, 300) skipped [300, 400) zero-filled afterwards The current code adds the full server range length, 200, to the current offset 100 and moves to 300. As a result, the hole in [200, 300) is skipped without being zero-filled. Fix this by advancing only over the part of the allocated range that overlaps the current fallocate offset. Ignore ranges that end before the current offset and reject ranges whose end offset overflows. This also prevents a malformed range length from causing an out-of-bounds zero-buffer read.

2026-07-13smb/client: refresh allocation size after duplicate extentsHuiwen He
FSCTL_DUPLICATE_EXTENTS_TO_FILE changes the target file extents on the server, but the client does not refresh the target AllocationSize/i_blocks. Callers can observe or use the wrong st_blocks value immediately after the clone, before a later attribute revalidation corrects it. For example, create a reflinked file with a leading hole: xfs_io -f -c "pwrite -S 0x61 0 64k" src touch dst chmod 600 dst xfs_io -c "reflink src 0 1m 64k" dst mkswap dst swapon dst The file still has a hole after mkswap: /mnt/scratch/dst: [0..7]: allocated [8..2047]: hole [2048..2175]: allocated The server also reports only the allocated ranges: server dst size=1114112 blocks=144 but the client reported EOF-derived blocks: client dst size=1114112 blocks=2176 and swapon succeeded: swapon_result=success /mnt/scratch/dst 1.1M 0B -1 So EOF-derived i_blocks can let a sparse reflinked file pass the CIFS swapfile hole check. Fix this by querying FILE_ALL_INFORMATION on the target handle after a successful duplicate extents request. Update i_blocks from AllocationSize and keep the refreshed target inode attributes valid so a following stat does not immediately revalidate again. If the query fails, mark the cached inode attributes stale so a later getattr can refresh them. This also fixes the xfstests generic/370 regression introduced by the i_blocks accounting change, as tested on a Samba "vfs objects = btrfs" share.

After consulting with the vendor's engineers, it was confirmed that this setting is board-specific and should be handled by BIOS/firmware rather than the generic codec driver, especially since inline remote support is not currently implemented.

2026-07-13arm64: dts: freescale: imx9-var-dart-sonata: fix Ethernet PHY configurationStefano Radaelli
Fix the Ethernet PHY description on the DART-MX9 Sonata boards. The GPIO previously described as the PHY reset line is actually a board-level enable signal required by the PHY. Model it accordingly and remove the incorrect reset GPIO description from the PHY nodes. On i.MX91 and i.MX93 the signal is described as a fixed regulator, whereas the existing regulator description on i.MX95 is reused. Keeping the PHY enable asserted during boot ensures that Ethernet initialization completes successfully.

2026-07-13firmware: qcom: scm: Add minidump SRAM supportMukesh Ojha
On most Qualcomm SoCs where minidump is supported, a word in always-on SRAM is shared between the operating system (OS) and boot firmware. Before DDR is initialized on the warm reset following a crash, firmware reads this word to decide if minidump is enabled and collect a minidump, and where to deliver it (USB upload to a host, or save to local storage). The OS is expected to select one of the destinations. The SRAM region is described by a 'sram' phandle on the SCM DT node. If the property is absent the feature is silently disabled, keeping existing SoCs unaffected. Expose a 'minidump_dest' module parameter (default: usb) so the user can select the destination. Only the string names "usb" or "storage" are accepted.

2026-07-13Bluetooth: mgmt: Translate HCI reason in Device Disconnected eventMikhail Gavrilov
MGMT_EV_DEVICE_DISCONNECTED carries a reason field which is defined to be one of MGMT_DEV_DISCONN_* (0x00..0x05). hci_disconn_complete_evt() converts the HCI error with hci_to_mgmt_reason(), but two other paths pass the raw HCI error straight through: hci_cs_disconnect() -> cp->reason mgmt_connect_failed() -> status The latter is reached whenever the adapter is powered off or suspended: hci_disconnect_all_sync() aborts every link with HCI_ERROR_REMOTE_POWER_OFF, hci_disconnect_sync() deliberately does not wait for HCI_EV_DISCONN_COMPLETE for that reason, so that hci_abort_conn_sync() finishes the connection off through hci_conn_failed() instead. As a result userspace sees an out of range reason: @ MGMT Event: Device Disconnected (0x000c) plen 8 BR/EDR Address: 8C:A9:6F:2C:51:46 Reason: Reserved (0x15) bluetoothd: btd_bearer_disconnected() Unknown disconnection value: 21 bluetoothd: device_disconnected() Unknown disconnection value: 21 Export hci_to_mgmt_reason() and use it in both places, so that a power off is reported as MGMT_DEV_DISCONN_REMOTE rather than as the raw HCI_ERROR_REMOTE_POWER_OFF (0x15).

2026-07-13Bluetooth: hci_qca: Clear memdump state on invalid dump sizeRuoyu Wang
qca_controller_memdump() allocates qca->qca_memdump before processing the first dump packet. For a sequence-zero packet it then disables IBS, marks memdump collection active, and reads the advertised dump size. If the controller reports a zero dump size, the error path frees the local qca_memdump object and returns without clearing qca->qca_memdump or undoing the collection state. A later memdump work item initializes its local pointer from qca->qca_memdump and skips allocation when that pointer is non-NULL, so it can operate on freed memory. The stale collection and IBS-disabled flags can also leave waiters or later transmit handling blocked behind an aborted dump. Clear the saved pointer and memdump state before returning from the invalid-size path, matching the cleanup used when hci_devcd_init() fails. A static analysis checker reported the stale memdump state, and manual source review confirmed the invalid-size failure path.
