Let's split out the logic that actually generates the word to measure to
PCRs into a new helper file pcrextend-util.[ch].
This we can later reuse to calculate PCR measurement predictions ahead
of time.
We'll soon have a function for determining the name of an NV index,
hence let's rename the existing function for the same of a public key to
make clear it's about public keys only.
modprobe treats "-" and "_" interchangeably, thereby avoiding frequent
errors because some module names contain dashes and others underscores.
Because modprobe@.service unescapes the instance name, an attempt to
start "modprobe@dm-crypt.service" will run "modprobe -abq dm/crypt",
which is doomed to fail. "modprobe@dm_crypt.service" will work as
expected. Thus unescaping the instance name has surprising side effects.
Use "%i" instead.
After 7470b80763, we refuse
to hibernate if we fail to write HibernateLocation EFI
variable and resume= is not set. Let's teach sleep_supported
to follow the practice too.
* "HibernateLocation" struct is renamed to HibernationDevice
to avoid ambiguity with the EFI variable. Also, it no longer
takes the reference to a SwapEntry object, since it's really
unnecessary (only SwapEntry.path is used), but increases complexity.
* SwapEntry is no longer used externally.
* find_hibernate_location is split into read_swap_entries and
find_suitable_hibernation_device. The former reads all swap entries
into SwapEntries object for later use.
* Make use of btrfs_get_file_physical_offset_fd
Closes#25130
If `foo+3-0.efi` is booted when there are some files in `foo.efi.extra.d`,
those files are ignored. But after the boot is blessed and the system rebooted,
those file are taken into account, and the boot is different from first
boot. This behavior is a bit puzzling.
Instead we now ignore the counter and always look for the extra files in
`foo.efi.extra.d` and always boot the same way.
mcopy will set the modification time of created directories to the mtime
of the source directories but converts it to the timezone of the host.
This behavior is identical to Windows / DOS:
> The FAT file system stores time values based on the local time of the computer.

To achieve reproducible builds, mcopy should be invoked with TZ=UTC.

Ultimately we want to be able to recognize these in userspace, hence
make them available in both UEFI mode and userspace.
While we are at it, let's rename the fields a bit, reflecting more what
they measure, not what the metadata is that we store about them.
