Although this patch is correct and at some point it will be re-introduced, currently shim does not support the loader protocol so drop it in the meanwhile. Signed-off-by: Leo Sandoval <lsandova@redhat.com>

Subject: [PATCH] Set non-executable stack sections on EFI assembly files
|
|
|
|
For those manual assembly files created where no '.note.GNU-stack'
|
|
section is explicitly added, linker defaults it as executable and this
|
|
is the reason that RHEL CI rpminspect & annocheck tests are
|
|
failing. The proposed change sets the corresponding GNU-stack
|
|
sections otherwise CI detects the following security vulnerability
|
|
|
|
$ annocheck annocheck --ignore-unknown --verbose --profile=el9 *.rpm 2>&1 | grep FAIL | grep stack
|
|
(standard input):(standard input):Hardened: ./usr/lib/grub/x86_64-efi/kernel.exec: FAIL: gnu-stack test because .note.GNU-stack section has execute permission
