Package: release.debian.org
Severity: normal
Tags: trixie
X-Debbugs-Cc: [email protected]
Control: affects -1 + src:gnu-efi
User: [email protected]
Usertags: pu
[ Reason ]
gnu-efi does not produce working UEFI binaries for armhf.
The details are in #1086705. This affects efibootguard but probably
other gnu-efi compiled binaries.
This stable update backports an upstream patch.
[ Impact ]
armhf-built EFI binaries, such as efibootguard's
/usr/lib/arm-linux-gnueabihf/efibootguard/efibootguardarm.efi
/usr/lib/arm-linux-gnueabihf/efibootguard/kernel-stubarm.efi
do not run, i.e. the armhf machine does not boot.
[ Tests ]
Two users have tested the backported patch with their armhf machines and
report it to work.
[ Risks ]
The patch only touches ARM 32 bit code, which is broken. The other archs
are not affected.
[ Checklist ]
[x] *all* changes are documented in the d/changelog
[x] I reviewed all changes and I approve them
[x] attach debdiff against the package in stable
[x] the issue is verified as fixed in unstable
[ Changes ]
The patch changes the handling of the _start symbol in 32 bit ARM assembly.
[ Other info ]
After this, a stable binNMU should run for the reverse build
dependencies if we have such a process. Otherwise I am going to file a
stable update for efibootguard after this is accepted.
