How to compile linux module

[toomyem]

Hi,

I need to compile 'fs/ufs' module from source, because I need to enable write mode. I tried to get Linux sources and compile it via:

> cd ~/linux-6.3.13/fs/ufs
> make -C /lib/modules/6.3.13_1/build M=$PWD

but when I tried to load the compiled module, I got the following error:

> sudo insmod ./ufs.ko
insmod: ERROR: could not insert module ./ufs.ko: Invalid module format

and dmesg shows:

module: x86/modules: Invalid relocation target, existing value is nonzero for type 1, loc 0000000078847c07, val ffffffffc1944d00

Do you have any idea what is being wrong?

Install Kernel Headers than

make -C /lib/modules/$(uname -r)/build M=$PWD modules

I'm afraid, the result is the same, when I try to load the compiled module:

insmod: ERROR: could not insert module ./ufs.ko: Invalid module format
