2024-09-12net/mlx5: Skip HotPlug check on sync reset using hot resetMoshe Shemesh
Sync reset request is nacked by the driver when PCIe bridge connected to mlx5 device has HotPlug interrupt enabled. However, when using reset method of hot reset this check can be skipped as Hotplug is supported on this reset method.

2024-09-12net/mlx5: Add support for sync reset using hot resetMoshe Shemesh
On device that supports sync reset for firmware activate using hot reset, the driver queries the required reset method while handling the sync reset request. If the required reset method is hot reset, the driver will use pci_reset_bus() to reset the PCI link instead of the link toggle.

2024-09-12net/mlx5: fs, add support for no append at software levelMark Bloch
Native capability for some steering engines lacks support for adding an additional match with the same value to the same flow group. To accommodate the NO APPEND flag in these scenarios, we include the new rule in the existing flow table entry (fte) without immediate hardware commitment. When a request is made to delete the corresponding hardware rule, we then commit the pending rule to hardware. Only one pending rule is supported because NO_APPEND is primarily used during replacement operations. In this scenario, a rule is initially added. When it needs replacement, the new rule is added with NO_APPEND set. Only after the insertion of the new rule is the original rule deleted.

2024-09-12mm: avoid leaving partial pfn mappings around in error caseLinus Torvalds
As Jann points out, PFN mappings are special, because unlike normal memory mappings, there is no lifetime information associated with the mapping - it is just a raw mapping of PFNs with no reference counting of a 'struct page'. That's all very much intentional, but it does mean that it's easy to mess up the cleanup in case of errors. Yes, a failed mmap() will always eventually clean up any partial mappings, but without any explicit lifetime in the page table mapping itself, it's very easy to do the error handling in the wrong order. In particular, it's easy to mistakenly free the physical backing store before the page tables are actually cleaned up and (temporarily) have stale dangling PTE entries. To make this situation less error-prone, just make sure that any partial pfn mapping is torn down early, before any other error handling.

2024-09-12Bluetooth: btusb: Fix not handling ZPL/short-transferLuiz Augusto von Dentz
Requesting transfers of the exact same size of wMaxPacketSize may result in ZPL/short-transfer since the USB stack cannot handle it as we are limiting the buffer size to be the same as wMaxPacketSize. Also, in terms of throughput this change has the same effect to interrupt endpoint as 290ba200815f "Bluetooth: Improve USB driver throughput by increasing the frame size" had for the bulk endpoint, so users of the advertisement bearer (e.g. BT Mesh) may benefit from this change.

2024-09-12drm/xe/client: add missing bo locking in show_meminfo()Matthew Auld
bo_meminfo() wants to inspect bo state like tt and the ttm resource, however this state can change at any point leading to stuff like NPD and UAF, if the bo lock is not held. Grab the bo lock when calling bo_meminfo(), ensuring we drop any spinlocks first. In the case of object_idr we now also need to hold a ref. v2 (MattB) - Also add xe_bo_assert_held() Fixes: 0845233388f8 ("drm/xe: Implement fdinfo memory stats printing") Signed-off-by: Matthew Auld <matthew.auld@intel.com> Cc: Himal Prasad Ghimiray <himal.prasad.ghimiray@intel.com> Cc: Tejas Upadhyay <tejas.upadhyay@intel.com> Cc: "Thomas Hellström" <thomas.hellstrom@linux.intel.com> Cc: <stable@vger.kernel.org> # v6.8+ Reviewed-by: Matthew Brost <matthew.brost@intel.com> Reviewed-by: Tejas Upadhyay <tejas.upadhyay@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240911155527.178910-6-matthew.auld@intel.com (cherry picked from commit 4f63d712fa104c3ebefcb289d1e733e86d8698c7) Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com>
2024-09-12drm/xe/client: fix deadlock in show_meminfo()Matthew Auld
There is a real deadlock as well as sleeping in atomic() bug in here, if the bo put happens to be the last ref, since bo destruction wants to grab the same spinlock and sleeping locks. Fix that by dropping the ref using xe_bo_put_deferred(), and moving the final commit outside of the lock. Dropping the lock around the put is tricky since the bo can go out of scope and delete itself from the list, making it difficult to navigate to the next list entry.
