[PATCH] grub-install: force journal draining to ensure data integrity

In XFS, the system would end up in unbootable state if an abrupt power off after grub-install is occuring. It can be easily reproduced with. grub-install /dev/vda; reboot -f The grub error would show many different kinds of corruption in filesystem and the problem boils down to incompleted jour

[PATCH v2] tests: Don't run f2fs test on systems with PAGE_SIZE more than 4096 bytes

Don't run f2fs test on systems with PAGE_SIZE > 4096 bytes, since f2fs is not supported on these systems and trying to mount a f2fs filesystem would fail. v2 changes: - fix compare - quotes around variable expansion Signed-off-by: Anatoly Pugachev Reviewed-by: Mike Gilbert --- tests/f2fs_tes

[PATCH 2/2] core: commands: efi: add commands to get/set EFI vars

Sometimes, using a GRUB boot script (i.e. grub.cfg), it is very important to get/set an EFI variable, especially in embedded systems, to detect some custom BIOS features. For example, based on the content of some EFI variables, a script can decide to boot a special kernel instead of the usual kerne

[PATCH 1/2] efi: add non-volatile parameter to grub_efi_set_variable

The current version of the function: grub_efi_set_variable always set an EFI variable as "non-volatile", since the variable attribute: GRUB_EFI_VARIABLE_NON_VOLATILE is fixed in the EFI SetVariable() call. With this change it is possible to decide if the written EFI variable is volatile or not

ASN.1 parsing for verifying appended signatures

Hi, I'd like to teach grub how to verify appended signatures. Appended signatures are a format used by the Linux kernel to cryptographically sign binaries. They're used to verify kernel modules on all platforms [1], and they're also used on some platforms (such as PowerPC) for signing the kernel i
