efi/libstub: move TPM related prototypes into efistub.h

2021-01-19T16:57:15Z

Move TPM related definitions that are only used in the EFI stub into efistub.h, which is a local header. Signed-off-by: Ard Biesheuvel

efi: ia64: disable the capsule loader

2020-12-14T15:24:19Z

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.

efi: generalize efi_get_secureboot

2020-11-04T22:05:40Z

Generalize the efi_get_secureboot() function so not only efistub but also other subsystems can use it. Note that the MokSbState handling is not factored out: the variable is boot time only, and so it cannot be parameterized as easily. Also, the IMA code will switch to this version in a future patch, and it does not incorporate the MokSbState exception in the first place. Note that the new efi_get_secureboot_mode() helper treats any failures to read SetupMode as setup mode being disabled.

efi: efivars: un-export efivars_sysfs_init()

2020-09-29T17:40:57Z

efivars_sysfs_init() is only used locally in the source file that defines it, so make it static and unexport it. Signed-off-by: Ard Biesheuvel

efi: pstore: move workqueue handling out of efivars

2020-09-29T17:40:57Z

The worker thread that gets kicked off to sync the state of the EFI variable list is only used by the EFI pstore implementation, and is defined in its source file. So let's move its scheduling there as well. Since our efivar_init() scan will bail on duplicate entries, there is no need to disable the workqueue like we did before, so we can run it unconditionally. Signed-off-by: Ard Biesheuvel

efi: pstore: disentangle from deprecated efivars module

2020-09-29T17:40:57Z

The EFI pstore implementation relies on the 'efivars' abstraction, which encapsulates the EFI variable store in a way that can be overridden by other backing stores, like the Google SMI one. On top of that, the EFI pstore implementation also relies on the efivars.ko module, which is a separate layer built on top of the 'efivars' abstraction that exposes the [deprecated] sysfs entries for each variable that exists in the backing store. Since the efivars.ko module is deprecated, and all users appear to have moved to the efivarfs file system instead, let's prepare for its removal, by removing EFI pstore's dependency on it.

efi: Add definition of EFI_MEMORY_CPU_CRYPTO and ability to report it

2020-09-25T21:29:04Z

Incorporate the definition of EFI_MEMORY_CPU_CRYPTO from the UEFI specification v2.8, and wire it into our memory map dumping routine as well. To make a bit of space in the output buffer, which is provided by the various callers, shorten the descriptive names of the memory types. Reviewed-by: Laszlo Ersek Signed-off-by: Ard Biesheuvel
