If the measurements are missing but it's a UEFI system, it's a good indication
that the user has secure boot turned off.
Notify the user on the UEFI device through a non-fatal `UpdateMessage`
To accomplish this, move fu-uefi-vars into the plugin library for other plugins to use
This makes everything simpler, at the expense of not being able to create a
`BootFFFF` entry -- but if we get that far something has already gone very
wrong with the firmware...
If we add or remove a quirk from a machine using the uefi plugin then the new
setting is not used until the BootXXXX EFI key is manually removed. Rather than
just writing the contents of the found key back to the key (doh) just write the
new DP buffer contents if it is different from the previous buffer.
I'm getting a bit fed up with failed reports from arch users where they just
have a broken system. I don't think it's useful to upload to the LVFS or notify
the vendor about failures like this.
Some system firmware helpfully 'deduplicate' the boot loader entries based on
the filepath, without taking into account either the label or optional data.
This means we have to use a custom copy of shim for firmware updates.
Some hardware from Lenovo deduplicates UEFI Boot entries, and uses the old
string 'Linux-Firmware-Updater' to avoid removing the firmware update entry.
Although this is forbidden in the UEFI specification we shouldn't break
firmware updates from old firmware versions.
Provide a quirk for this, and automatically whitelist anything with the LENOVO
SMBIOS Manufacturer.
Unfortunately the previous fix (6131f5d) introduced this bug.
The code previously was actually looking for the non-zero case
which was correct, but non-obvious since `efi_guid_cmp` works like
`g_strcmp0` where a match returns zero.
So rather than revert 6131f5d make this completly explicit.
1) Drop the path at the end of the title (\fwupdx64.efi)
2) Linux-Firmware-Updater to Linux Firmware Updater
The behavior that required the hacky name has been fixed since shim 10
which is in all the relevant distros now.
