#1014840 — Bug#963475: libefivar1: "efibootmgr -v" fails with "Could not parse device path: Invalid argument"

Package: libefivar1
Version: 37-2.1
Severity: important

Hello!

One week ago I had no issues in running:

  $ efibootmgr -v

but today, I get:

  $ efibootmgr -v
  BootCurrent: 0001
  Timeout: 1 seconds
  BootOrder: 0001,0000
  Boot0000* debianCould not parse device path: Invalid argument

Please note that (luckily!) the system is able to boot and reboot,
and that the non-verbose output is:

  $ efibootmgr
  BootCurrent: 0001
  Timeout: 1 seconds
  BootOrder: 0001,0000
  Boot0000* debian
  Boot0001* debian2

I searched the web and found a github [issue], that claims the
problem is in efivar, mentioning a [commit] that is supposed
to fix it.
But it seems to me that the [code] currently in Debian unstable
does not include this fix.

[issue]: <https://github.com/rhboot/efibootmgr/issues/133>
[commit]: <https://github.com/rhboot/efivar/commit/4e04afc2df9bbc26e5ab524b53a6f4f1e61d7c9e>
[code]: <https://sources.debian.org/src/efivar/37-2.1/src/ucs2.h/>

I hope I am not completely off-track...   :-p

Could you please investigate the issue and cherrypick the patch,
if appropriate?

Thanks for your time.

I tried to downgrade from libefiboot1/37-2.1 to libefiboot1/37-2 and I
can confirm that the problem vanishes after the downgrade.

Is there any news on your side?
Please let me know, thanks for your time!

Hello,

What's preventing the upstream fix from being applied to this package?

Hello,

I applied the fix and built the package. It didn't help. I also built
latest master and I still have this issue.

BTW, the computer is an OptiPlex 7040. Full hwinfo --bios:

FWIW, I'm also experiencing the issue that efibootmgr -v produces the
error "Could not parse device path: Invalid argument" with libefiboot1
37-2.1, but not 37-2.  Building libefiboot1 with fdb8034 and 4e04afc
added to debian/patches does solve the issue for me.

Best,
Kevin

P.S. I had to build using GCC 9 due to

It was efibootmgr and efivar master.

#1019541 — Bug#963475: Could not parse device path: Invalid argument

Hello,

I was filing a new bug against efibootmgr, but my issue might belong
here as well.

When I invoke `efibootmgr -v`, it gives the error `Could not parse
device path: Invalid argument`

```
omer@omer:~$ efibootmgr
BootCurrent: 0003
Timeout: 1 seconds
BootOrder: 0000,0003,0001,0002
Boot0000* Windows Boot Manager
Boot0001  Hard Drive
Boot0002  USB HDD
Boot0003* debian
omer@omer:~$ efibootmgr -v
BootCurrent: 0003
Timeout: 1 seconds
BootOrder: 0000,0003,0001,0002
Boot0000* Windows Boot ManagerCould not parse device path: Invalid argument
```

A similar error was also reported against Ubuntu [1] and Fedora [2].

[1]: https://bugs.launchpad.net/ubuntu/+source/efivar/+bug/1844320
[2]: https://bugzilla.redhat.com/show_bug.cgi?id=1773175

I have dual boot with Windows 10 and Bullseye. I came across this
error while I was trying to figure out a way to edit Windows' GPT
entry (so that my PC boots to grub even after Windows 10 tampers GPT
entries to put its own boot manager in the first place).

Package versions:

ii  efibootmgr        17-1         amd64        Interact with the EFI
Boot Manager
ii  libc6:amd64       2.31-1       amd64        GNU C Library: Shared libraries
ii  libefiboot1:amd64 37-2.1       amd64        Library to manage UEFI variables
ii  libefivar1:amd64  37-2.1       amd64        Library to manage UEFI variables
ii  libpopt0:amd64    1.18-1       amd64        lib for parsing
cmdline parameter

In my case, when I compiled the latest efivar [3], `efibootmgr -v` ran
without any issues with the compiled shared objects libefivar.so.1 and
libefiboot.so.1 in its LD_LIBRARY_PATH.

#1019731 — Bug#963475: Could not parse device path: Invalid argument

Hello,

I tested `efibootmgr -v` from Debian testing in QEMU and had the `Could
not parse device path: Invalid argument` error. Then I downloaded
Fedora 32 live, run `efibootmgr -v` and got a nice output:
```
[liveuser@localhost-live ~]$ sudo efibootmgr -v
BootCurrent: 0001
Timeout: 0 seconds
BootOrder: 0001,0000,0005

Boot0001* UEFI QEMU DVD-ROM QM00001 	PciRoot(0x0)/Pci(0x1f,0x2)/Sata

3ee4af6516a1)/FvFile(7c04a583-9e3e-4f1c-ad65-e05268d0b4d1)
```

I think that the Debian package should have this patch applied.
