This metadata is temporary and is used by the next kernel during early boot to find preserved memory. A problem arises when KFENCE is enabled. kzalloc() calls can be randomly intercepted by kfence_alloc(), which services the allocation from a dedicated KFENCE memory pool. This pool is allocated early in boot via memblock. When booting via KHO, the memblock allocator is restricted to a "scratch area", forcing the KFENCE pool to be allocated within it. This creates a conflict, as the scratch area is expected to be ephemeral and overwriteable by a subsequent kexec. If KHO metadata is placed in this KFENCE pool, it leads to memory corruption when the next kernel is loaded. To fix this, modify KHO to allocate its metadata directly from the buddy allocator instead of slab.

Slabs are not safe to be used with KHO because of kfence, and because partial slabs may lead leaks to the next kernel. Change the size to be PAGE_SIZE. The kfence specifically may cause memory corruption, where it randomly provides slab objects that can be within the scratch area. The reason for that is that kfence allocates its objects prior to KHO scratch is marked as CMA region. While this change could potentially increase metadata overhead on systems with sparsely preserved memory, this is being mitigated by ongoing work to reduce sparseness during preservation via 1G guest pages. Furthermore, this change aligns with future work on a stateless KHO, which will also use page-sized bitmaps for its radix tree metadata.

This series fixes a memory corruption bug in KHO that occurs when KFENCE is enabled. The root cause is that KHO metadata, allocated via kzalloc(), can be randomly serviced by kfence_alloc(). When a kernel boots via KHO, the early memblock allocator is restricted to a "scratch area". This forces the KFENCE pool to be allocated within this scratch area, creating a conflict. If KHO metadata is subsequently placed in this pool, it gets corrupted during the next kexec operation. Google is using KHO and have had obscure crashes due to this memory corruption, with stacks all over the place. I would prefer this fix to be properly backported to stable so we can also automatically consume it once we switch to the upstream KHO. Patch 1/3 introduces a debug-only feature (CONFIG_KEXEC_HANDOVER_DEBUG) that adds checks to detect and fail any operation that attempts to place KHO metadata or preserved memory within the scratch area. This serves as a validation and diagnostic tool to confirm the problem without affecting production builds. Patch 2/3 Increases bitmap to PAGE_SIZE, so buddy allocator can be used. Patch 3/3 Provides the fix by modifying KHO to allocate its metadata directly from the buddy allocator instead of slab. This bypasses the KFENCE interception entirely. This patch (of 3): It is invalid for KHO metadata or preserved memory regions to be located within the KHO scratch area, as this area is overwritten when the next kernel is loaded, and used early in boot by the next kernel. This can lead to memory corruption. Add checks to kho_preserve_* and KHO's internal metadata allocators (xa_load_or_alloc, new_chunk) to verify that the physical address of the memory does not overlap with any defined scratch region. If an overlap is detected, the operation will fail and a WARN_ON is triggered. To avoid performance overhead in production kernels, these checks are enabled only when CONFIG_KEXEC_HANDOVER_DEBUG is selected.

On AMD SMCA systems, this essentially disables polling on that particular bank on that CPU. Consequently, any subsequent correctable errors or storms will not be logged. Since AMD SMCA systems allow banks to be managed by both polling and interrupts, the polling banks bitmap for a CPU, i.e., mce_poll_banks, should not be modified when a storm subsides.

[PATCH 0/2] drm/xe: Fix and refactor CONFIG_DRM_XE_DEBUG_GUC

by Lucas De Marchi

There was a missing call to stack_depot_init() that is needed if CONFIG_DRM_XE_DEBUG_GUC is defined. That is fixed in the simplest possible way in the first patch. Second patch refactors it to try to isolate the ifdefs in specific functions related to CONFIG_DRM_XE_DEBUG and CONFIG_DRM_XE_DEBUG_GUC.

[PATCH] lib/crypto: tests: Fix KMSAN warning in test_sha256_finup_2x()

by Eric Biggers

Fully initialize *ctx, including the buf field which sha256_init() doesn't initialize, to avoid a KMSAN warning when comparing *ctx to orig_ctx. This KMSAN warning slipped in while KMSAN was not working reliably due to a stackdepot bug, which has now been fixed.

[PATCH v2] usb: phy: Initialize struct usb_phy list_head

by Diogo Ivo

As part of the registration of a new 'struct usb_phy' with the USB PHY core via either usb_add_phy(struct usb_phy *x, ...) or usb_add_phy_dev(struct usb_phy *x) these functions call list_add_tail(&x->head, phy_list) in order for the new instance x to be stored in phy_list, a static list kept internally by the core. After 7d21114dc6a2 ("usb: phy: Introduce one extcon device into usb phy") when executing either of the registration functions above it is possible that usb_add_extcon() fails, leading to either function returning before the call to list_add_tail(), leaving x->head uninitialized. Then, when a driver tries to undo the failed registration by calling usb_remove_phy(struct usb_phy *x) there will be an unconditional call to list_del(&x->head) acting on an uninitialized variable, and thus a possible NULL pointer dereference. Fix this by initializing x->head before usb_add_extcon() has a chance to fail. Note that this was not needed before 7d21114dc6a2 since list_add_phy() was executed unconditionally and it guaranteed that x->head was initialized.

The second condition was then always true then, and the 'else' branch was never taken. The idea is that when there are more ACK + MP_CAPABLE than expected, the test either fails if there was no out of order packets, or a notice is printed.

[PATCH] usb: phy: Initialize struct usb_phy list_head

by Diogo Ivo

When executing usb_add_phy() and usb_add_phy_dev() it is possible that usb_add_extcon() fails (for example with -EPROBE_DEFER), in which case the usb_phy does not get added to phy_list via list_add_tail(&x->head, phy_list). Then, when the driver that tried to add the phy receives the error propagated from usb_add_extcon() and calls into usb_remove_phy() to undo the partial registration there will be an unconditional call to list_del(&x->head) which is notinitialized and leads to a NULL pointer dereference. Fix this by initializing x->head before usb_add_extcon() has a chance to fail.

[PATCH] mm/mmap_lock: Reset maple state on lock_vma_under_rcu() retry

by Liam R. Howlett

The retry in lock_vma_under_rcu() drops the rcu read lock before reacquiring the lock and trying again. This may cause a use-after-free if the maple node the maple state was using was freed. The maple state is protected by the rcu read lock. When the lock is dropped, the state cannot be reused as it tracks pointers to objects that may be freed during the time where the lock was not held. Any time the rcu read lock is dropped, the maple state must be invalidated. Resetting the address and state to MA_START is the safest course of action, which will result in the next operation starting from the top of the tree. Prior to commit 0b16f8bed19c ("mm: change vma_start_read() to drop RCU lock on failure"), the rcu read lock was dropped and NULL was returned, so the retry would not have happened. However, now that the read lock is dropped regardless of the return, we may use a freed maple tree node cached in the maple state on retry.
