Hey there, I'm trying to compile a single module following this guide:
https://wiki.centos.org/HowTos/BuildingKernelModules#head-d2e4c05886f94c701e...
and
https://wiki.centos.org/HowTos/I_need_the_Kernel_Source
I tried to compile a module for novuton led controller supplied by thirdparty and I got several error.
To check if this is the wrong procedure I tried to compile cifs module as listed in howto but when loading with modprobe I get "Exec format error", and from dmesg "cifs: no symbol version for module_layout ", the same errors when compiling novuton module and I don't know why I get this error.
When following the instructions in BuildingKernelModules, which kernel version did you use? Also, after the "depmod -a" step, what is the output from:
$ modinfo cifs | grep filename
I noticed that modules in centos are compressed in .xz but after running make M=fs/cifs I got only a .ko kernel module and then I run xz to compress the new module.
Compressing modules is optional. Uncompressed form is functionally the same (of course it saves some disk space).
Can someone help me please?
Thanks in advance.

Hi Akemi, thank you for your answer.
Kernel version used is 3.10.0-957.27.2.el7.x86_64
[root@c7-test SPECS]# modinfo cifs | grep filename filename: /lib/modules/3.10.0-957.27.2.el7.x86_64/extra/cifs.ko
Looking good. I assume your running kernel is 3.10.0-957.27.2.el7 ?

Reading from dmesg seems that the module is not accepted by kernel due to invalid signature. I need to sign the module with a key?
Thanks in advance
