Date: Mon, 1 Aug 2022 15:41:15 +0200 From: Ard Biesheuvel To: torvalds@linux-foundation.org Cc: linux-efi@vger.kernel.org, keescook@chromium.org, Ard Biesheuvel Subject: [GIT PULL 0/2] EFI pull requests for v5.20 Hello Linus, I am sending this cycle's EFI changes as two separate pull requests: - the first one covers the normal updates accumulated this cycle, including some cleanup of the 'efivars' layer; - the second one removes the obsolete 'efivars' sysfs driver, and consolidates the remaining code related to manipulating arbitrary EFI variables from user space into the efivarfs pseudo-filesystem driver. The 'efivars' sysfs interface and the 'efivarfs' (note the 'f') pseudo-filesystem are both based on an abstraction which is also called 'efivars' that caches EFI variables, and permits the backend to be swapped out, for backing the EFI variable store by, e.g., SMI calls or other secure firmware calls. (only used by Google SMI at the moment, but new uses are being proposed). Using two cached views of the same variable store leads to the problems you might expect, and other users also exist that (ab)use the efivars layer for non-obvious reasons. Most of the quirks are being cleaned up in 1/2 of this PR series. However, to really address this thoroughly, we should get rid of the obsolete sysfs based EFI variable interface for user space, and only keep the efivarfs pseudo-filesystem. This is what is implemented by 2/2 of this PR series, which also moves the remaining efivars logic that efivarfs relies on into the efivarfs driver, and no longer exports it to other parts of the kernel. Obviously, removing the sysfs interface could potentially break someone's workflow somewhere, and so it is not without risk. However, as far as I can infer from things like Debian code search etc, all support libraries that are in use to access EFI variables will prefer the efivarfs pseudo-filesystem, and fall back to the sysfs interface otherwise. The efivarfs pseudo-FS is 'default m' when CONFIG_EFI=y, and all the distros have switched to it a very long time ago. But individual cases might exist where a script accesses /sys/firmware/efi/vars/... directly, and this will no longer work after merging PR 2/2 of this series. In summary, I am leaving it up to you to pull the trigger on PR 2/2 - if you prefer to deal with this in a different way, please feel free to disregard the second PR, and make a suggestion how to address this instead. Note that the 2/2 changes were put at the end so reverting this should be quite straight-forward, in case we do decide to merge them and they turn out to be causing problems. Thanks, Ard. .

The main driver for this has been the introduction of the LoonArch architecture last cycle, which inspired some cleanup and refactoring of the EFI code. Another driver for EFI changes this cycle and in the future is confidential compute. The LoongArch architecture does not use either struct bootparams or DT natively [yet], and so passing information between the EFI stub and the core kernel using either of those is undesirable. And in general, overloading DT has been a source of issues on arm64, so using DT for this on new architectures is a to avoid for the time being (even if we might converge on something DT based for non-x86 architectures in the future). For this reason, in addition to the patch that enables EFI boot for LoongArch, there are a number of refactoring patches applied on top of which separate the DT bits from the generic EFI stub bits. These changes are on a separate topich branch that has been shared with the LoongArch maintainers, who will include it in their pull request as well. This is not ideal, but the best way to manage the conflicts without stalling LoongArch for another cycle. Another development inspired by LoongArch is the newly added support for EFI based decompressors. Instead of adding yet another arch-specific incarnation of this pattern for LoongArch, we are introducing a EFI app based on the existing EFI libstub infrastructure that encapulates the decompression code we use on other architectures, but in a way that is fully generic. This has been developed and tested in collaboration with distro and systemd folks, who are eager to start using this for systemd-boot and also for arm64 secure boot on Fedora. Note that the EFI zimage files this introduces can also be decompressed by non-EFI bootloaders if needed, as the image header describes the location of the payload inside the image, and the type of compression that was used. (Note that Fedora's arm64 GRUB is buggy [0] so you'll need a recent version or switch to systemd-boot in order to use this.) Finally, we are adding TPM measurement of the kernel command line provided by EFI. There is an oversight in the TCG spec which results in a blind spot for command line arguments passed to loaded images, which means that either the loader or the stub needs to take the measurement. Given the combinatorial explosion I am anticipating when it comes to firmware/bootloader stacks and firmware based attestation protocols (SEV-SNP, TDX, DICE, DRTM), it is good to set a baseline now when it comes to EFI measured boot, which is that the kernel measures the initrd and command line. Intermediate loaders can measure additional assets if needed, but with the baseline in place, we can deploy measured boot in a meaningful way even if you boot into Linux straight from the EFI firmware. Please pull the changes below. -- Ard.

The other patch adds an SMBIOS based quirk for Ampere Altra machines. This is the first time we've added such a quirk on arm64, but fortunately, we can just call a EFI protocol to grab the type #1 SMBIOS record when running in the stub, so we don't need all the machinery we have in the kernel proper to parse SMBIOS data.

Most of the work was done by me, some of it in collaboration with the distro and bootloader folks (GRUB, systemd-boot), where the main focus has been on removing pointless per-arch differences in the way EFI boots a Linux kernel. There were a few conflicts reported, with the arm64 and tip trees, but nothing too hairy. Some of the conflicts were with some of my own work landing via a different tree, but in those cases, the changes in question were mostly unrelated, had been on the list for a while and simply happened to land now so I don't think there is much I could have done about that.

There is one minor conflict [0] in arch/arm64/include/asm/efi.h against a fix that went into -rc8, but not worth the hassle of merging back the EFI fixes branch, so you'll have to fix that up (if you don't mind). Thanks, Ard. The following changes since commit 1b929c02afd37871d5afb9d498426f83432e71c2: Linux 6.2-rc1 (2022-12-25 13:41:39 -0800) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/efi/efi.git tags/efi-next-for-v6.3 for you to fetch changes up to e1d447157f232c650e6f32c9fb89ff3d0207c69a: firmware/efi sysfb_efi: Add quirk for Lenovo IdeaPad Duet 3 (2023-02-19 14:41:33 +0100) [0] https://lore.kernel.org/all/20230220135844.73e9dcae@canb.auug.org.au/ ---------------------------------------------------------------- A healthy mix of EFI contributions this time: - Performance tweaks for efifb earlycon by Andy - Preparatory refactoring and cleanup work in the efivar layer by Johan, which is needed to accommodate the Snapdragon arm64 laptops that expose their EFI variable store via a TEE secure world API. - Enhancements to the EFI memory map handling so that Xen dom0 can safely access EFI configuration tables (Demi Marie) - Wire up the newly introduced IBT/BTI flag in the EFI memory attributes table, so that firmware that is generated with ENDBR/BTI landing pads will be mapped with enforcement enabled. - Clean up how we check and print the EFI revision exposed by the firmware. - Incorporate EFI memory attributes protocol definition contributed by Evgeniy and wire it up in the EFI zboot code. This ensures that these images can execute under new and stricter rules regarding the default memory permissions for EFI page allocations. (More work is in progress here) - CPER header cleanup by Dan Williams - Use a raw spinlock to protect the EFI runtime services stack on arm64 to ensure the correct semantics under -rt.

This PR primarily covers some cleanup work on the EFI runtime wrappers, which are shared between all EFI architectures except Itanium, and which provide some level of isolation to prevent faults occurring in the firmware code (which runs at the same privilege level as the kernel) from bringing down the system. Beyond that, there is a fix that did not make it into v6.5, and some doc fixes and dead code cleanup. Please pull.

The unaccepted memory table needs to be accessible very early, even in cases (such as crashkernels) where the direct map does not cover all of DRAM, and so it is added to memblock explicitly, and subsequently memblock_reserve()'d as before.

Only notable change here is the patch that changes the way we deal with spurious errors from the EFI memory attribute protocol. This will be backported to v6.6, and is intended to ensure that we will not paint ourselves into a corner when we tighten this further in order to comply with MS requirements on signed EFI code. Note that this protocol does not currently exist in x86 production systems in the field, only in Microsoft's fork of OVMF, but it will be mandatory for Windows logo certification for x86 PCs in the future.

This is going be backported to v6.1 and later to address the regression described in the commit. Whether or not physical KASLR for the cases in question will be brought back later (presumably by sharing the physical placement logic with the traditional decompressor) is as yet undecided.

Details are in the tag. Note the removal of the EFI fake memory map support - this is believed to be unused and no longer worth supporting. However, we could easily bring it back if needed. (With recent developments regarding confidential VMs and unaccepted memory, combined with kexec, creating a known inaccurate view of the firmware's memory map and handing it to the OS is a feature we can live without, hence the removal. Alternatively, I could imagine making this feature mutually exclusive with those confidential VM related features, but let's try simply removing it first) The following changes since commit f2661062f16b2de5d7b6a5c42a9a5c96326b8454: Linux 6.10-rc5 (2024-06-23 17:08:54 -0400) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/efi/efi.git tags/efi-next-for-v6.11 for you to fetch changes up to 4a2ebb082297f41803742729642961532e54079e: efi: Replace efi_memory_attributes_table_t 0-sized array with flexible array (2024-07-12 10:06:01 +0200) ---------------------------------------------------------------- EFI updates for v6.11 - Drop support for the 'fake' EFI memory map on x86 - Add an SMBIOS based tweak to the EFI stub instructing the firmware on x86 Macbook Pros to keep both GPUs enabled - Replace 0-sized array with flexible array in EFI memory attributes table handling - Drop redundant BSS clearing when booting via the native PE entrypoint on x86 - Avoid returning EFI_SUCCESS when aborting on an out-of-memory condition - Cosmetic tweak for arm64 KASLR loading logic ---------------------------------------------------------------- Aditya Garg (1): x86/efistub: Call Apple set_os protocol on dual GPU Intel Macs Ard Biesheuvel (6): x86/efi: Drop support for fake EFI memory maps efistub/smbios: Simplify SMBIOS enumeration API x86/efistub: Enable SMBIOS protocol handling for x86 x86/efistub: Avoid returning EFI_SUCCESS on error x86/efistub: Drop redundant clearing of BSS arm64/efistub: Clean up KASLR logic Kees Cook (2): efi: Rename efi_early_memdesc_ptr() to efi_memdesc_ptr() efi: Replace efi_memory_attributes_table_t 0-sized array with flexible array Documentation/admin-guide/kernel-parameters.txt | 21 --- arch/x86/Kconfig | 20 --- arch/x86/boot/compressed/kaslr.c | 43 ++--- arch/x86/include/asm/efi.h | 22 +-- arch/x86/kernel/setup.c | 1 - arch/x86/platform/efi/Makefile | 1 - arch/x86/platform/efi/efi.c | 2 - arch/x86/platform/efi/fake_mem.c | 197 ----------------------- arch/x86/platform/efi/memmap.c | 1 + drivers/firmware/efi/libstub/Makefile | 2 +- drivers/firmware/efi/libstub/arm64-stub.c | 13 +- drivers/firmware/efi/libstub/arm64.c | 3 +- drivers/firmware/efi/libstub/efistub.h | 9 +- drivers/firmware/efi/libstub/kaslr.c | 20 +-- drivers/firmware/efi/libstub/relocate.c | 2 +- drivers/firmware/efi/libstub/smbios.c | 43 +++-- drivers/firmware/efi/libstub/unaccepted_memory.c | 2 +- drivers/firmware/efi/libstub/x86-stub.c | 83 ++++++++-- drivers/firmware/efi/memattr.c | 2 +- include/linux/efi.h | 15 +- 20 files changed, 146 insertions(+), 356 deletions(-) delete mode 100644 arch/x86/platform/efi/fake_mem.c .
