We use a macro efi_bs_call() to call boot services, which is more concise, and on x86, it encapsulates the mixed mode handling. This code does not run in mixed mode, but let's switch to the macro for general tidiness. Signed-off-by: Ard Biesheuvel <ardb@kernel.org>

The EFI TCG spec, in §10.2.6 "Measuring UEFI Variables and UEFI GPT Data", only reasons about the load options passed to a loaded image in the context of boot options booted directly from the BDS, which are measured into PCR #5 along with the rest of the Boot#### EFI variable. However, the UEFI spec mentions the following in the documentation of the LoadImage() boot service and the EFI_LOADED_IMAGE protocol: The caller may fill in the image’s "load options" data, or add additional protocol support to the handle before passing control to the newly loaded image by calling EFI_BOOT_SERVICES.StartImage(). The typical boot sequence for Linux EFI systems is to load GRUB via a boot option from the BDS, which [hopefully] calls LoadImage to load the kernel image, passing the kernel command line via the mechanism described above. This means that we cannot rely on the firmware implementing TCG measured boot to ensure that the kernel command line gets measured before the image is started, so the EFI stub will have to take care of this itself. Given that PCR #5 has an official use in the TCG measured boot spec, let's avoid it in this case. Instead, add a measurement in PCR #9 (which we already use for our initrd) and extend it with the LoadOptions measurements Co-developed-by: Ilias Apalodimas <ilias.apalodimas@linaro.org> Signed-off-by: Ilias Apalodimas <ilias.apalodimas@linaro.org> Signed-off-by: Ard Biesheuvel <ardb@kernel.org>

Currently, from the efi-stub, we are only measuring the loaded initrd, using the TCG2 measured boot protocols. A following patch is introducing measurements of additional components, such as the kernel command line. On top of that, we will shortly have to support other types of measured boot that don't expose the TCG2 protocols. So let's prepare for that, by rejigging the efi_measure_initrd() routine into something that we should be able to reuse for measuring other assets, and which can be extended later to support other measured boot protocols.

Second shared stable tag between EFI and LoongArch trees This is necessary because the EFI libstub refactoring patches are mostly directed at enabling LoongArch to wire up generic EFI boot support without being forced to consume DT properties that conflict with information that EFI also provides, e.g., memory map and reservations, etc.
-
Ard Biesheuvel authored
LoongArch does not use FDT or DT natively [yet], and the only reason it currently uses it is so that it can reuse the existing EFI stub code. Overloading the DT with data passed between the EFI stub and the core kernel has been a source of problems: there is the overlap between information provided by EFI which DT can also provide (initrd base/size, command line, memory descriptions), requiring us to reason about which is which and what to prioritize. It has also resulted in ABI leaks, i.e., internal ABI being promoted to external ABI inadvertently because the bootloader can set the EFI stub's DT properties as well (e.g., "kaslr-seed"). This has become especially problematic with boot environments that want to pretend that EFI boot is being done (to access ACPI and SMBIOS tables, for instance) but have no ability to execute the EFI stub, and so the environment that the EFI stub creates is emulated [poorly, in some cases]. Another downside of treating DT like this is that the DT binary that the kernel receives is different from the one created by the firmware, which is undesirable in the context of secure and measured boot. Given that LoongArch support in Linux is brand new, we can avoid these pitfalls, and treat the DT strictly as a hardware description, and use a separate handover method between the EFI stub and the kernel. Now that initrd loading and passing the EFI memory map have been refactored into pure EFI routines that use EFI configuration tables, the only thing we need to pass directly is the kernel command line (even if we could pass this via a config table as well, it is used extremely early, so passing it directly is preferred in this case.)

Refactor the generic EFI stub entry code so that all the dependencies on device tree are abstracted and hidden behind a generic efi_boot_kernel() routine that can also be implemented in other ways. This allows users of the generic stub to avoid using FDT for passing information to the core kernel. Signed-off-by: Ard Biesheuvel <ardb@kernel.org>

Use a EFI configuration table to pass the initrd to the core kernel, instead of per-arch methods. This cleans up the code considerably, and should make it easier for architectures to get rid of their reliance on DT for doing EFI boot in the future. Signed-off-by: Ard Biesheuvel <ardb@kernel.org>

Ard Biesheuvel authored
Currently, struct efi_boot_memmap is a struct that is passed around between callers of efi_get_memory_map() and the users of the resulting data, and which carries pointers to various variables whose values are provided by the EFI GetMemoryMap() boot service. This is overly complex, and it is much easier to carry these values in the struct itself. So turn the struct into one that carries these data items directly, including a flex array for the variable number of EFI memory descriptors that the boot service may return.

The virt map is a set of efi_memory_desc_t descriptors that are passed to SetVirtualAddressMap() to inform the firmware about the desired virtual mapping of the regions marked as EFI_MEMORY_RUNTIME. The only reason we currently call the efi_get_memory_map() helper is that it gives us an allocation that is guaranteed to be of sufficient size. However, efi_get_memory_map() has grown some additional complexity over the years, and today, we're actually better off calling the EFI boot service directly with a zero size, which tells us how much memory should be enough for the virt map. While at it, avoid creating the VA map allocation if we will not be using it anyway, i.e., if efi_novamap is true. Signed-off-by: Ard Biesheuvel <ardb@kernel.org>

Implement a minimal EFI app that decompresses the real kernel image and launches it using the firmware's LoadImage and StartImage boot services. This removes the need for any arch-specific hacks. Note that on systems that have UEFI secure boot policies enabled, LoadImage/StartImage require images to be signed, or their hashes known a priori, in order to be permitted to boot. There are various possible strategies to work around this requirement, but they all rely either on overriding internal PI/DXE protocols (which are not part of the EFI spec) or omitting the firmware provided LoadImage() and StartImage() boot services, which is also undesirable, given that they encapsulate platform specific policies related to secure boot and measured boot, but also related to memory permissions (whether or not and which types of heap allocations have both write and execute permissions.) The only generic and truly portable way around this is to simply sign both the inner and the outer image with the same key/cert pair, so this is what is implemented here.

The stub is used in different execution environments, but on arm64, RISC-V and LoongArch, we still use the core kernel's implementation of memcpy and memset, as they are just a branch instruction away, and can generally be reused even from code such as the EFI stub that runs in a completely different address space. KAsan complicates this slightly, resulting in the need for some hacks to expose the uninstrumented, __ prefixed versions as the normal ones, as the latter are instrumented to include the KAsan checks, which only work in the core kernel. Unfortunately, #define'ing memcpy to __memcpy when building C code does not guarantee that no explicit memcpy() calls will be emitted. And with the upcoming zboot support, which consists of a separate binary which therefore needs its own implementation of memcpy/memset anyway, it's better to provide one explicitly instead of linking to the existing one. Given that EFI exposes implementations of memmove() and memset() via the boot services table, let's wire those up in the appropriate way, and drop the references to the core kernel ones.

EFI boot support for loongarch
-
Huacai Chen authored
This patch adds efistub booting support, which is the standard UEFI boot protocol for LoongArch to use. We use generic efistub, which means we can pass boot information (i.e., system table, memory map, kernel command line, initrd) via a light FDT and drop a lot of non-standard code. We use a flat mapping to map the efi runtime in the kernel's address space. In efi, VA = PA; in kernel, VA = PA + PAGE_OFFSET. As a result, flat mapping is not identity mapping, SetVirtualAddressMap() is still needed for the efi runtime.

Move the EFI mixed mode return trampoline RET into .rodata, so it is normally mapped without executable permissions. And given that this snippet of code is really the only kernel code that we ever execute via this 1:1 mapping, let's unmap the 1:1 mapping of the kernel .text, and only map the page that covers the return trampoline with executable permissions. Note that the remainder of .rodata needs to remain mapped into the 1:1 mapping with RO/NX permissions, as literal GUIDs and strings may be passed to the variable routines.

Enable multipage folio support for the afs filesystem. Support has already been implemented in netfslib, fscache and cachefiles and in most of afs, but I've waited for Matthew Wilcox's latest folio changes. Note that it does require a change to afs_write_begin() to return the correct subpage. This is a "temporary" change as we're working on getting rid of the need for ->write_begin() and ->write_end() completely, at least as far as network filesystems are concerned - but it doesn't prevent afs from making use of the capability.
