2023-07-09efi_loader: Increase default variable store size to 64KiBAlper Nebi Yasak
Debian's arm64 UEFI Secure Boot shim makes the EFI variable store run out of space while mirroring its MOK database to variables. This can be observed in QEMU like so: $ tools/buildman/buildman -o build/qemu_arm64 --boards=qemu_arm64 -w $ cd build/qemu_arm64 $ curl -L -o debian.iso \ https://cdimage.debian.org/debian-cd/current/arm64/iso-cd/debian-12.0.0-arm64-netinst.iso $ qemu-system-aarch64 \ -nographic -bios u-boot.bin \ -machine virt -cpu cortex-a53 -m 1G -smp 2 \ -drive if=virtio,file=debian.iso,index=0,format=raw,readonly=on,media=cdrom [...] => # interrupt autoboot => env set -e -bs -nv -rt -guid 605dab50-e046-4300-abb6-3dd810dd8b23 SHIM_VERBOSE 1 => boot [...] mok.c:296:mirror_one_esl() SetVariable("MokListXRT43", ... varsz=0x4C) = Out of Resources mok.c:452:mirror_mok_db() esd:0x7DB92D20 adj:0x30 Failed to set MokListXRT: Out of Resources mok.c:767:mirror_one_mok_variable() mirror_mok_db("MokListXRT", datasz=17328) returned Out of Resources mok.c:812:mirror_one_mok_variable() returning Out of Resources Could not create MokListXRT: Out of Resources [...] Welcome to GRUB! This would normally be fine as shim would continue to run grubaa64.efi, but shim's error handling code for this case has a bug [1] that causes a synchronous abort on at least chromebook_kevin (but apparently not on QEMU arm64). Double the default variable store size so the variables fit. There is a note about this value matching PcdFlashNvStorageVariableSize when EFI_MM_COMM_TEE is enabled, so keep the old default in that case.

2023-07-09efi_loader: Avoid underflow when calculating remaining var store sizeAlper Nebi Yasak
The efi_var_mem_free() function calculates the available size for a new EFI variable by subtracting the occupied buffer size and the overhead for a new variable from the maximum buffer size set in Kconfig. This is then returned as QueryVariableInfo()'s RemainingVariableStorageSize output. This can underflow as the calculation is done in and processed as unsigned integer types. Check for underflow before doing the subtraction and return zero if there's no space.

2023-06-08efi_loader: store firmware version into FmpState variableMasahisa Kojima
Firmware version management is not implemented in the current FMP protocol. EDK II reference implementation capsule generation script inserts the FMP Payload Header right before the payload, FMP Payload Header contains the firmware version and lowest supported version. This commit utilizes the FMP Payload Header, reads the header and stores the firmware version into "FmpStateXXXX" EFI non-volatile variable. XXXX indicates the image index, since FMP protocol handles multiple image indexes. Note that lowest supported version included in the FMP Payload Header is not used. If the platform uses file-based EFI variable storage, it can be tampered. The file-based EFI variable storage is not the right place to store the lowest supported version for anti-rollback protection. This change is compatible with the existing FMP implementation. This change does not mandate the FMP Payload Header. If no FMP Payload Header is found in the capsule file, fw_version, lowest supported version, last attempt version and last attempt status is 0 and this is the same behavior as existing FMP implementation.

In lack of some supported board with NAND flash I couldn't really test this part, but apparently this was tested by the reviewer. I briefly ran the branch on some boards with USB-OTG, and this still worked.

Remove test on CONFIG_LMB_MEMORY_REGIONS introduced by commit 7c1860fce4e3 ("lmb: Fix lmb property's defination under struct lmb"). This code in lmb_init() is strange, because if CONFIG_LMB_USE_MAX_REGIONS and CONFIG_LMB_MEMORY_REGIONS are not defined, the implicit #else is empty and the required initialization is not done: lmb->memory.max = ? lmb->reserved.max = ? But this setting is not possible: - CONFIG_LMB_USE_MAX_REGIONS not defined - CONFIG_LMB_MEMORY_REGIONS not defined because CONFIG_LMB_MEMORY_REGIONS and CONFIG_LMB_RESERVED_REGIONS are defined as soon as the CONFIG_LMB_USE_MAX_REGIONS is not defined. This patch removes this impossible case #elif and I add some explanation in lmb.h to explain why in the struct lmb {} the lmb property is defined if CONFIG_LMB_MEMORY_REGIONS is NOT defined.
