git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull EFI fix from Borislav Petkov: "Ensure that the EFI bootloader control module only probes successfully on systems that support the EFI SetVariable runtime service" [ Tag and commit from Ard Biesheuvel, forwarded by Borislav ] * tag 'efi-urgent-for-v5.9-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: efi: efibc: check for efivars write capability
2020-09-15efi: efibc: check for efivars write capabilityArd Biesheuvel1-1/+1
Branden reports that commit f88814cc2578c1 ("efi/efivars: Expose RT service availability via efivars abstraction") regresses UEFI platforms that implement GetVariable but not SetVariable when booting kernels that have EFIBC (bootloader control) enabled. The reason is that EFIBC is a user of the efivars abstraction, which was updated to permit users that rely only on the read capability, but not on the write capability. EFIBC is in the latter category, so it has to check explicitly whether efivars supports writes.

2020-09-10test_firmware: Test platform fw loading on non-EFI systemsKees Cook1-5/+5
On non-EFI systems, it wasn't possible to test the platform firmware loader because it will have never set "checked_fw" during __init. Instead, allow the test code to override this check. Additionally split the declarations into a private symbol namespace so there is greater enforcement of the symbol visibility.

There is no real functional benefit, but this documents the intent of these calls better, and will allow stubbing the functions out easily for kernels builds that do not allow address space overrides in the future.

Add support for the Inline Crypto Engine (ICE) key programming interface that's needed for the ufs-qcom driver to use inline encryption on Snapdragon SoCs. This interface consists of two SCM calls: one to program a key into a keyslot, and one to invalidate a keyslot. Although the UFS specification defines a standard way to do this, on these SoCs the Linux kernel isn't permitted to access the needed crypto configuration registers directly; these SCM calls must be used instead.

2020-07-18firmware: turris-mox-rwtm: support ECDSA signatures via debugfsMarek Behún1-0/+166
The firmware on Turris MOX secure processor offers signing messages with ECDSA private key stored in protected OTP memory. The optimal solution would be to register an akcipher provider via kernel's crypto API, but crypto API does not yet support accessing akcipher API from userspace (and probably won't for some time, see https://www.spinics.net/lists/linux-crypto/msg38388.html). At first I tried to put this via standard sysfs API, but the way I designed it is not compatible with sysfs's standard "one file per attribute". This patch therefore adds support for accessing this signature generation mechanism via debugfs. Since CZ.NIC's Turris MOX is the only user of this module, the potential future change to akcipher API should not cause problems, since we can just change our userspace software then.

This breaks these helpers on hardware that uses the old legacy convention (access fails with a -95 return code). Switch back to using the atomic calls.

2020-07-13efi/libstub/arm64: Retain 2MB kernel Image alignment if !KASLRWill Deacon2-12/+15
Since commit 82046702e288 ("efi/libstub/arm64: Replace 'preferred' offset with alignment check"), loading a relocatable arm64 kernel at a physical address which is not 2MB aligned and subsequently booting with EFI will leave the Image in-place, relying on the kernel to relocate itself early during boot. In conjunction with commit dd4bc6076587 ("arm64: warn on incorrect placement of the kernel by the bootloader"), which enables CONFIG_RELOCATABLE by default, this effectively means that entering an arm64 kernel loaded at an alignment smaller than 2MB with EFI (e.g. using QEMU) will result in silent relocation at runtime. Unfortunately, this has a subtle but confusing affect for developers trying to inspect the PC value during a crash and comparing it to the symbol addresses in vmlinux using tools such as 'nm' or 'addr2line'; all text addresses will be displaced by a sub-2MB offset, resulting in the wrong symbol being identified in many cases. Passing "nokaslr" on the command line or disabling "CONFIG_RANDOMIZE_BASE" does not help, since the EFI stub only copies the kernel Image to a 2MB boundary if it is not relocatable. Adjust the EFI stub for arm64 so that the minimum Image alignment is 2MB unless KASLR is in use.

Substitute scmi_event_header fixed size fields with generic types too and shuffle around fields definitions to minimize implicit padding while adapting involved functions.
