Thanks for maintaining this!

Hopefully this is a gentle nudge, but no kernel-devel packages are provided.

bieszczaders · February 25, 2023, 5:40pm

We provide.

grantson · February 25, 2023, 6:02pm

You do! My apologies, the amdgpu installer was looking for a hardcoded package name. I’ll sort that out.

Hiya. Could we please get the *.srpm for the 6.2.1 LTO build? I’m enabling SELINUX and I need the *.spec file . Also, I really appreciate you maintaining this.

Currently not available @ https://download.copr.fedorainfracloud.org/results/bieszczaders/kernel-cachyos/fedora-37-x86_64/05566183-kernel-cachyos-bore-lto/

EDIT: Please disregard. I found the .spec files. That’s very handy, thanks again.

Hey! Thanks for this. Working just fine!

Have you managed to make SELinux work? I’ve tried the autolabel method but didnt work, i’ve checked out the config for compiling at:

github.com

and the kernel supports it, so by the autolabel method should work, right?
If someone manages to make SELinux work, please tell me!

I do have SELINUX working on my build. I did it by adding:

scripts/config --set-str CONFIG_LSM “lockdown,yama,integrity,selinux,bpf,landlock”

to the .spec file and building.

you basically need your .config file to be changed from:

CONFIG_LSM=“landlock,lockdown,yama,integrity,bpf” >> CONFIG_LSM=“landlock,lockdown,yama,integrity,bpf,selinux”

Summary: It has to be defined in CONFIG_LSM to function as expected.

Disclaimer: I’m not sure if the order in CONFIG_LSM is important. I took my string from the stock Fedora kernel config.

piekha · March 4, 2023, 3:58pm

Oh, thank you very much, didnt see that.

But I guess it would be great to have the next builds from copr have selinux support implemented right, will do a request on github.

bieszczaders · March 4, 2023, 6:08pm

In release 6.2.3 we will enable proper selinux support.

sirlucjan · March 4, 2023, 6:41pm

Here’s a test repository as well, when it builds I would very much appreciate feedback on whether everything meets expectations:

razthecat · March 5, 2023, 4:27pm

No problem, I’m just glad I could help. I thought about suggesting it, but some people disable SELINUX for its possible performance implications. It’s neat that it’s getting merged upstream. I look forward to testing it.

razthecat · March 5, 2023, 4:54pm

I can confirm that the test repository build is successfully running on my hardware with SELINUX enabled. Thank you.

testing

sirlucjan · March 5, 2023, 7:57pm

We’ll see how it works out. At the most, I will leave the SELinux entry commented and then everyone can compile it for themselves. I’m glad I could help and thanks also for testing.

razthecat · March 5, 2023, 8:49pm

You’re very welcome. Thanks for maintaining this!

lejeczek · March 30, 2023, 2:04pm

I wonder if would put Centos Stream on your radar as well - that would be great if you did.

sirlucjan · March 31, 2023, 9:26pm

Could you test?

lejeczek · April 16, 2023, 6:15am

Thanks. Would be great if you guys could also fix repo so ‘dnf copr’ would work.

→ $ dnf copr enable bieszczaders/kernel-cachyos

We don’t have "epel-9-x86_64 " support here. If you want, we could add. Did you test kernel on Centos-Steam (from -dev repo)?

lejeczek · April 17, 2023, 12:10pm

Yes. Can hardly call a test what I’ve done - a few tools brake/fail - but kernel-cachyos-bore-lto-6.2.9-cbl1.0.el9.x86_64 seems to run a ok.
