The upstream patch has an additional fix but it?s not critical for GA. It can
get included as part of bug fixes. It also affects only power. The
patch("powerpc/ima: fix secure boot rules in ima arch policy") is posted to

Tested the updated ppa kernel.
Everything looks good and here are the test results:
secure boot is enabled as seen by device-tree entry "os-secure-enforcing"

We did some testing with that patch (previous comment) on top of the
5.4.0-21.25+lp1866909v202004020814 source/config file. We signed the
kernel/modules and securely booted it. That fixed the module loading issue we
were

We've been working with Mimi and I think that what we need now aren't config
option changes, but this patch:
diff --git a/arch/powerpc/kernel/ima_arch.c b/arch/powerpc/kernel/ima_arch.c

Sorry, we don't know if we want CONFIG_MODULE_SIG_FORCE set. The modules
aren't loading, and we weren't sure what needed to change. We're happy to try
a kernel with IMA_ARCH_POLICY if that fixed it on x86.

We did check the modules - at least the package
5.4.0-21.25+lp1866909v202004020814 and from modinfo:
signer: Build time autogenerated kernel key

With Michael's help, I could get the right key for the kernel.
I updated the new key and then tried booting to signed kernel in secure boot
enabled state.
It seems kernel is being verified.
# kexec -l

The kernel seems to be having the secure boot functions after enabling those
CONFIGs. Now, I was trying to boot to this kernel when secure boot is enabled.
I have taken the key from here -

Thank you, I grabbed that.
Is there any chance of a PPA respin with those options? We did test on
our rebuild, but we can't completely test without those options on plus
the signing.

Thank you for spinning that so quickly. We neglected to request these config
options get turned on:
CONFIG_PPC_SECURE_BOOT=y
CONFIG_PPC_SECVAR_SYSFS=y
CONFIG_LOAD_PPC_KEYS=y
CONFIG_IMA_READ_POLICY=y
CONFIG_IMA_ARCH_POLICY=y

Hi Frank,
That's what I see, too, and all of those are in focal already, along
with the other three whose titles matched. The config options in
500c7ab1a9db are already on in focal, too.
The ones we're not sure of are these
15 matches
