Kernel mnodule not found on RHEL/Rocky 9.4 using kABI

[tuxmaster5000]

On RHEL 9.4 the kernel module will not be found using the kABI version.

modinfo zfs
modinfo: ERROR: Module zfs not found.

OS Kernel: 5.14.0-427.16.1.el9_4.x86_64 package: kmod-zfs-2.1.15-2.el9.x86_64

Thanks for reporting this. It looks like RHEL updated their patch version minor number:	RHEL	ZFS kmod
5.14.0-427.16.1	5.14.0-427.13.1

I will rebuild the kmods. In the meantime you can use the DKMS packages if you want.

@tuxmaster5000 I uploaded the new kmods - please give it another try.

Hi, I have tried the new packages. And after signing the modules it will work. Do you have an idea, when the problem with the lost module signatures will be resolved? Because until now I must sign the kernel modules after every update with my own key, because the modules from the rpm package are not signed and then an secure boot system will refuse loading the modules.

[tonyhutter]

The modules don't really need to be signed since we sign the RPMs and the repository:

$ rpm -qpi http://download.zfsonlinux.org/epel/9.4/kmod/x86_64/kmod-zfs-2.1.15-3.el9.x86_64.rpm | grep -i signature
warning: http://download.zfsonlinux.org/epel/9.4/kmod/x86_64/kmod-zfs-2.1.15-3.el9.x86_64.rpm: Header V4 RSA/SHA256 Signature, key ID 9db84141: NOKEY

@tonyhutter Unfortunately, you are wrong. Because secureboot requires signed modules.

@tonyhutter kmod is outdated again, current state:	RHEL	ZFS kmod
5.14.0-427.22.1	5.14.0-427.16.1

[tonyhutter]

@0x444D thanks. The old 2.1.15 kmods work fine under 5.14.0-427.22.1 (due to weak-modules), but the 2.2.4 kmods in the zfs-testing-kmod repo do not work. I'll rebuild those.

[tonyhutter]

@0x444D the new zfs-testing-kmod repo has been updated with the new kmods
