virt: efi_secret: Convert to platform remove callback returning void (2024-03-09 11:37:18 +0100)
----------------------------------------------------------------
EFI updates for v6.9:
- Measure initrd and command line using the CC protocol if the ordinary
TCG2 protocol is not implemented, typically on TDX confidential VMs
- Avoid creating mappings that are both writable and executable while
running in the EFI boot services. This is a prerequisite for getting
the x86 shim loader signed by MicroSoft again, which allows the
distros to install on x86 PCs that ship with EFI secure boot enabled.
- API update for struct platform_driver::remove()
----------------------------------------------------------------
Ard Biesheuvel (4):
efi/libstub: Use TPM event typedefs from the TCG PC Client spec
efi/tpm: Use symbolic GUID name from spec for final events table
efi/libstub: Measure into CC protocol if TCG2 protocol is absent
x86/efistub: Remap kernel text read-only before dropping NX attribute
Kuppuswamy Sathyanarayanan (2):
efi/libstub: Add Confidential Computing (CC) measurement typedefs
efi/libstub: Add get_event_log() support for CC platforms
Uwe Kleine-König (1):
