Hello Experts,
I'm trying to enable some infiniband related kernel modules (ib_ipoib,
iser, isert, etc) on my RHEL 7.6 instance running on IBM linuxONE
machine. (I have found the code in the kernel source tree.)
After installing the kernel source rpm in a normal user and make module
selection using the "make menuconfig" command, i can successfully
re-built all the selected modules (include the new selection) with the
"make modules" command.
I copied the desired module files to the
"/lib/modules/3.10.0-957.el7.s390x/kernel/drivers/infiniband/ulp" dir
and the depmod -a command also was executed with no errors.
[root@bz094f ulp]# pwd
/lib/modules/3.10.0-957.el7.s390x/kernel/drivers/infiniband/ulp
[root@bz094f ulp]#
[root@bz094f ulp]# ls -l ipoib
total 5704
-rw-r--r--. 1 root root 5837016 Dec 9 15:50 ib_ipoib.ko
[root@bz094f ulp]# ls -l iser
total 2880
-rw-r--r--. 1 root root 2946496 Dec 9 15:50 ib_iser.ko

total 1384
-rw-r--r--. 1 root root 1414304 Dec 9 15:50 ib_isert.ko
[root@bz094f ulp]#
But after reboot the OS, i found the new copied modules can't be loaded
by the kernel.
errors reported in the /var/log/message:

Alexander,
Thanks for the reminder!
I realized that the new build module is with version "3.10.0" and so not
match with my running kernel version "3.10.0-957.el7.s390x".
I do confirm that i was using the right kernel source rpm.
So, the question turns to why the "make modules" command changed the
kernel version of built modules to "3.10.0" instead of
"3.10.0-957.el7.s390x".
Is there any special steps i need to follow to keep the original kernel
naming convention?
btw: I'm following below article to compile the kernel modules.

Thanks!

When I try to install the new built kernel and modules, i found the
install script will assign the kernel version as "3.10.0".
Where is this defined?
Can we keep it as the current kernel version or change it as we want?

In your setup, CONFIG_LOCALVERSION is probably set to 3.10.0.
If that is the case, try setting CONFIG_LOCALVERSION="" via 'make
menuconfig', and ensure that CONFIG_LOCALVERSION_AUTO is set to 'y'.
Where is this defined?
Can we keep it as the current kernel version or change it as we want?

Alexander,
Thanks for the reminder!
I realized that the new build module is with version "3.10.0" and so not
match with my running kernel version "3.10.0-957.el7.s390x".
I do confirm that i was using the right kernel source rpm.
So, the question turns to why the "make modules" command changed the
kernel version of built modules to "3.10.0" instead of
"3.10.0-957.el7.s390x".
Is there any special steps i need to follow to keep the original kernel
naming convention?
btw: I'm following below article to compile the kernel modules.

You mentioned that you were following the instructions to build your
modules using this article,
https://wiki.centos.org/HowTos/BuildingKernelModules.
Which method did you use?
Some of the methods describe setting the kernel version in their
respective config files. E.g. cifs-kmod.spec.
Perhaps your build environment relies on those config files to set the
version of the kernel module?

When I try to install the new built kernel and modules, i found the
install script will assign the kernel version as "3.10.0".
The kernel version is set via these config options via scripts/setlocalversion:
CONFIG_LOCALVERSION
CONFIG_LOCALVERSION_AUTO
In your setup, CONFIG_LOCALVERSION is probably set to 3.10.0.
If that is the case, try setting CONFIG_LOCALVERSION="" via 'make
menuconfig', and ensure that CONFIG_LOCALVERSION_AUTO is set to 'y'.

Where is this defined?
Can we keep it as the current kernel version or change it as we want?

Alexander,
Thanks for the reminder!
I realized that the new build module is with version "3.10.0" and so not
match with my running kernel version "3.10.0-957.el7.s390x".
I do confirm that i was using the right kernel source rpm.
So, the question turns to why the "make modules" command changed the
kernel version of built modules to "3.10.0" instead of
"3.10.0-957.el7.s390x".
Is there any special steps i need to follow to keep the original kernel
naming convention?
btw: I'm following below article to compile the kernel modules.
https://wiki.centos.org/HowTos/BuildingKernelModules
Thanks!

You mentioned that you were following the instructions to build your
modules using this article,
https://wiki.centos.org/HowTos/BuildingKernelModules.
Which method did you use?
Some of the methods describe setting the kernel version in their
respective config files. E.g. cifs-kmod.spec.
Perhaps your build environment relies on those config files to set the
version of the kernel module?
