CentOS-Stream-9

[rajesh0110]

Hi,

My setup is on VirtualBox 7.0 environment.

I had been using the 09/12 Stream9 build (Kernel:5.14.0-364.el9.x86_64) and I had no problem in compiling our KO modules and running them.
Just 2 weeks later, I was doing the same with the 09/25 Stream9 (Kernel: 5.14.0-368.el9.x86_64). I was using the latest available Stream9.

After compiling our KO modules, the modprobe and the insmod fails with the following errors:

Error reported on the UI:
-----------------------------
modprobe: ERROR: could not insert <MODULE_NAME>: Exec format error

The dmesg output is:
-------------------------
[ 1744.494543] module: x86/modules: Skipping invalid relocation target, existing value is nonzero for type 1, loc 00000000e5bf8a0c, val ffffffffc0b162a6

The packages were installed were:
kernel-headers-`uname -r`
kernel-devel

I saw the same problem with my RHEL 9 setup also. Based on the information I gathered, I tried reinstalling the kernel-headers. I just could not find any other suggestions. From the source code I looked at in the Kernel, looks like the value should be "0" for type 1 (x86_64).

Any pointers is appreciated to resolve this.
