2020-12-14efi: ia64: disable the capsule loaderArd Biesheuvel
EFI capsule loading is a feature that was introduced into EFI long after its initial introduction on Itanium, and it is highly unlikely that IA64 systems are receiving firmware updates in the first place, let alone using EFI capsules. So let's disable capsule support altogether on IA64. This fixes a build error on IA64 due to a recent change that added an unconditional include of asm/efi.h, which IA64 does not provide. While at it, tweak the make rules a bit so that the EFI capsule component that is always builtin (even if the EFI capsule loader itself is built as a module) is omitted for all architectures if the module is not enabled in the build.

2020-12-09efi/efi_test: read RuntimeServicesSupportedHeinrich Schuchardt
Since the UEFI 2.8A specification the UEFI enabled firmware provides a configuration table EFI_RT_PROPERTIES_TABLE which indicates which runtime services are enabled. The EFI stub reads this table and saves the value of the field RuntimeServicesSupported internally. The Firmware Test Suite requires the value to determine if UEFI runtime services are correctly implemented. With this patch an IOCTL call is provided to read the value of the field RuntimeServicesSupported, e.g. #define EFI_RUNTIME_GET_SUPPORTED_MASK \ _IOR('p', 0x0C, unsigned int) unsigned int mask; fd = open("/dev/efi_test", O_RDWR); ret = ioctl(fd, EFI_RUNTIME_GET_SUPPORTED_MASK, &mask); Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Link: https://lore.kernel.org/r/20201127192051.1430-1-xypron.glpk@gmx.de Acked-by: Colin Ian King <colin.king@canonical.com> Acked-by: Ivan Hu <ivan.hu@canonical.com> Signed-off-by: Ard Biesheuvel <ardb@kernel.org>
2020-12-09efi: capsule: clean scatter-gather entries from the D-cacheArd Biesheuvel
Scatter-gather lists passed to UpdateCapsule() should be cleaned from the D-cache to ensure that they are visible to the CPU after a warm reboot before the MMU is enabled. On ARM and arm64 systems, this implies a D-cache clean by virtual address to the point of coherency. However, due to the fact that the firmware itself is not able to map physical addresses back to virtual addresses when running under the OS, this must be done by the caller.

2020-12-02arm64: sdei: move uaccess logic to arch/arm64/Mark Rutland
The SDEI support code is split across arch/arm64/ and drivers/firmware/, largley this is split so that the arch-specific portions are under arch/arm64, and the management logic is under drivers/firmware/. However, exception entry fixups are currently under drivers/firmware. Let's move the exception entry fixups under arch/arm64/. This de-clutters the management logic, and puts all the arch-specific portions in one place. Doing this also allows the fixups to be applied earlier, so things like PAN and UAO will be in a known good state before we run other logic. This will also make subsequent refactoring easier.

2020-11-25efi: EFI_EARLYCON should depend on EFIGeert Uytterhoeven
CONFIG_EFI_EARLYCON defaults to yes, and thus is enabled on systems that do not support EFI, or do not have EFI support enabled, but do satisfy the symbol's other dependencies. While drivers/firmware/efi/ won't be entered during the build phase if CONFIG_EFI=n, and drivers/firmware/efi/earlycon.c itself thus won't be built, enabling EFI_EARLYCON does force-enable CONFIG_FONT_SUPPORT and CONFIG_ARCH_USE_MEMREMAP_PROT, and CONFIG_FONT_8x16, which is undesirable. Fix this by making CONFIG_EFI_EARLYCON depend on CONFIG_EFI. This reduces kernel size on headless systems by more than 4 KiB.

2020-11-25efi/efivars: Set generic ops before loading SSDTAmadeusz Sławiński
Efivars allows for overriding of SSDT tables, however starting with commit bf67fad19e493b ("efi: Use more granular check for availability for variable services") this use case is broken. When loading SSDT generic ops should be set first, however mentioned commit reversed order of operations. Fix this by restoring original order of operations.

Currently array of fix length PM_API_MAX is used to cache the pm_api version (valid or invalid). However ATF based PM APIs values are much higher then PM_API_MAX. So to include ATF based PM APIs also, use hash-table to store the pm_api version status.

For sake of consistency, remove any residual naming based on _le suffixes in SCMI sensors protocol, since little endianness is already assumed across all of SCMI implementation and, as such, all currently existent names do not explicitly state their endianness.

2020-11-21x86/mce, cper: Pass x86 CPER through the MCA handling chainSmita Koralahalli
The kernel uses ACPI Boot Error Record Table (BERT) to report fatal errors that occurred in a previous boot. The MCA errors in the BERT are reported using the x86 Processor Error Common Platform Error Record (CPER) format. Currently, the record prints out the raw MSR values and AMD relies on the raw record to provide MCA information. Extract the raw MSR values of MCA registers from the BERT and feed them into mce_log() to decode them properly. The implementation is SMCA-specific as the raw MCA register values are given in the register offset order of the SMCA address space.

2020-11-20crypto: sha - split sha.h into sha1.h and sha2.hEric Biggers
Currently <crypto/sha.h> contains declarations for both SHA-1 and SHA-2, and <crypto/sha3.h> contains declarations for SHA-3. This organization is inconsistent, but more importantly SHA-1 is no longer considered to be cryptographically secure. So to the extent possible, SHA-1 shouldn't be grouped together with any of the other SHA versions, and usage of it should be phased out. Therefore, split <crypto/sha.h> into two headers <crypto/sha1.h> and <crypto/sha2.h>, and make everyone explicitly specify whether they want the declarations for SHA-1, SHA-2, or both. This avoids making the SHA-1 declarations visible to files that don't want anything to do with SHA-1. It also prepares for potentially moving sha1.h into a new insecure/ or dangerous/ directory.
