smbios: Fix wrong sysinfo ID for Type 3 enclosure asset tag

2026-06-08T19:29:03Z

smbios_write_type3() uses SYSID_SM_BASEBOARD_ASSET_TAG (Type 2) instead of SYSID_SM_ENCLOSURE_ASSET_TAG (Type 3) for the enclosure asset tag. This causes the enclosure's asset tag to be read from the baseboard sysinfo field rather than the enclosure-specific one.

lmb: Rename LMB_LIMIT_DMA_BELOW_4G to LMB_LIMIT_DMA_BELOW_RAM_TOP

Rename LMB_LIMIT_DMA_BELOW_4G to LMB_LIMIT_DMA_BELOW_RAM_TOP to make the Kconfig option more descriptive. No functional change. Suggested-by: Ilias Apalodimas Signed-off-by: Marek Vasut Reviewed-by: Ilias Apalodimas

efi_loader: validate PE-COFF relocation data

2026-06-07T14:43:06Z

When applying base relocations from a PE-COFF binary all data must be treated as untrusted. Add the following checks to efi_loader_relocate(): * Reject relocation blocks that don't start on a 32-bit aligned address. * Reject relocation blocks whose SizeOfBlock is smaller than the block header, which would cause an unsigned underflow when computing the entry count. * A block with SizeOfBlock == 0 is invalid and does not mark the end of the relocation table. * Reject relocation blocks that extend beyond the end of the relocation section. * Reject individual relocation entries whose target offset, together with the access width, exceeds the mapped image size, preventing out-of-bounds writes. Pass virt_size to efi_loader_relocate() from efi_load_pe() to enable the per-entry bounds check.

efi_selftest: test hii keyboard layouts more

2026-05-18T06:38:16Z

The HII database test for keyboard layouts register two package lists with two keyboard layouts each, but the test verifies only the GUID of the first keyboard layout. This does not catch the bugs happening with the keyboard layouts after the first one in a package. Verify all the keyboard layout GUIDs in the unit test to prevent this.

efi_loader: fix hii keyboard layout pointer computation

2026-05-18T06:38:16Z

The EFI_HII_KEYBOARD_LAYOUT field `layout_length' is expressed in bytes, but we add it to the `layout' pointer with (scaled) pointer arithmetic. When adding an HII keyboard package with multiple keyboard layouts, this results in only the first layout being added correctly; fix it.

efi_loader: fix AllocatePages overlap status

2026-05-18T06:32:58Z

Return EFI_NOT_FOUND for EFI_ALLOCATE_ADDRESS overlap When efi_allocate_pages() is called with EFI_ALLOCATE_ADDRESS, UEFI expects EFI_NOT_FOUND if the requested address range is already allocated or unavailable. U-Boot currently returns EFI_OUT_OF_RESOURCES when efi_update_memory_map() detects an overlap after a successful lmb_alloc_mem(), which does not match EFI_ALLOCATE_ADDRESS semantics. Return EFI_NOT_FOUND for EFI_ALLOCATE_ADDRESS requests that fail due to an overlapping EFI memory descriptor, while keeping EFI_OUT_OF_RESOURCES for other allocation types. The UEFI specification [1] specifies that EFI_BOOT_SERVICES.AllocatePages must return EFI_NOT_FOUND when the requested address range is unavailable or already allocated; EFI_OUT_OF_RESOURCES applies to non‑address‑specific allocation failures. [1] https://uefi.org/specs/UEFI/2.10_A/07_Services_Boot_Services.html Signed-off-by: Harsimran Singh Tungal The UEFI specification does not clearly specify the behavior. But let's follow the EDK II precedent here. Reviewed-by: Heinrich Schuchardt

smbios: Do not fall back on devicetree without valid mapping

2026-05-15T14:18:11Z

The smbios_get_val_si() function may get called for a sysinfo property for which there is no mapping to a devicetree property. Avoid a NULL pointer dereference in this case by skipping the read of the mapped property from the device tree.

fwu: add helper to get image GUID by type and bank index

2026-05-12T13:52:01Z

Introduce fwu_mdata_get_image_guid() to retrieve a specific image GUID from the FWU metadata based on the bank index and image type GUID. This allows identifying the correct partition in multi-bank (A/B) scenarios, ensuring the correct image is targeted depending on the current bank.
