Hey there,
I'm trying to compile a single module following this guide:
https://wiki.centos.org/HowTos/BuildingKernelModules#head-d2e4c05886f94c701e4ae74387d41d8c40c25d01
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 ?
Akemi
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?
Do you have secureboot enabled? Then yes, that requires a proper key.
Akemi

Yes I have secureboot enabled. If usefull to others in list this could
helps:
https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/Kernel_Administration_Guide/sect-signing-kernel-modules-for-secure-boot.html
I think also that centos's wiki must be updated because steps are valid
for centos 5 and because key-signing is required for secure boot I think
that a proper section must be inserted.
