- avoid the error message during linux system boot (bsc#1184454) - prevent the build id being added to the binary. That can cause issues with the signature OBS-URL: https://build.opensuse.org/request/show/883796 OBS-URL: https://build.opensuse.org/package/show/devel:openSUSE:Factory/shim?expand=0&rev=177

Subject: [PATCH] mok: allocate MOK config table as BootServicesData
|
|
|
|
Linux kernel is picky when reserving the memory for x86 and it only
|
|
expects BootServicesData:
|
|
|
|
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/arch/x86/platform/efi/quirks.c?h=v5.11#n254
|
|
|
|
Otherwise, the following error would show during system boot:
|
|
|
|
Apr 07 12:31:56.743925 localhost kernel: efi: Failed to lookup EFI memory descriptor for 0x000000003dcf8000
|
|
|
|
Although BootServicesData would be reclaimed after ExitBootService(),
|
|
linux kernel reserves MOK config table when it detects the existence of
|
|
the table, so it's fine to allocate the table as BootServicesData.
