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.

2024-09-12drm/xe: Don't keep stale pointer to bo->ggtt_nodeMichal Wajdeczko
When we fail to map a BO in the GGTT, we release our GGTT node placeholder, but leave stale bo->ggtt_node pointer to it, which triggers an assert immediately followed by a crash, due to UAF: [ ] xe 0000:00:02.0: [drm] Assertion `bo->ggtt_node->base.size == bo->size` failed!

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.

The xe->pm_callback_task won't be equal 'current' because this call is coming from a work queue. So, pm_runtime_get_if_active() will be called and return 0 because rpm status != ACTIVE (but equal SUSPENDING or RESUMING). v2: Still get the reference even on non suspending/resuming path (Jonathan, Brost).
