[Bug 2043084] Please test proposed package

[Łukasz Zemczak]

Hello Chengen, or anyone else affected,

Accepted grub2-unsigned into focal-proposed. The package will build now
and be available at
https://launchpad.net/ubuntu/+source/grub2-unsigned/2.06-2ubuntu14.5 in
a few hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, what testing has been
performed on the package and change the tag from verification-needed-
focal to verification-done-focal. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-focal. In either case, without details of your testing we will
not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance for helping!

N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.

Bug description:
  [Impact]
  The GRUB menu fails to load via HTTP boot but functions properly with PXE boot, displaying the error message:
  error: Fail to send a request! status=0x8000000000000002.

  The error code 0x8000000000000002 corresponds to GRUB_EFI_INVALID_PARAMETER.
  Notably, this issue is unreproducible in QEMU but surfaces on BlueField.

  [Fix]
  Bisecting Oracle's patches, we confirmed with the customer that the issue was resolved with the following commit:
   https://github.com/rhboot/grub2/commit/205b7b44bb2a7911f1e8c1ce22d66c111a4b429e

  [Test Plan]
  We've requested the customer to test the patch on BlueField.
  Our test plan will focus on checking for any regressions after applying this patch and will include testing on machines in the Canonical hyperscale lab.

  1. Run a DHCP server on the host and configure /etc/dhcp/dhcpd.conf with the provided content.
  ...
  host http_boot {
    option host-name "http_boot";
    hardware ethernet XX:XX:XX:XX:XX:XX;
    fixed-address 192.168.122.10;
    class "HTTPClient" {
      match if substring (option vendor-class-identifier, 0, 10) = "HTTPClient";
      option vendor-class-identifier "HTTPClient";
      filename <-efi's path->;
    }
  }
  ...
  2. Start a UEFI VM and use "virsh console" for access.
  3. Execute "systemctl reboot --firmware-setup" in the console to enter the UEFI interface.
  4. Test the successful loading of the GRUB menu by selecting "Boot Manager" -> "UEFI HTTPv4."

  [Where problems could occur]
  The patch only updates a member variable type to comply with UEFI 2.9, preserving the original behavior.
  In QEMU, using EFI v2.70 from EDK II, we can still access the GRUB menu.
