Hi All:<br>
<br>
I have downloaded and installed 4.4.32-1.el7.elrepo.x86_64 from elrepo-lt,<br>
I'm not patching kernel modules against 4.4.32 source code from<br>
<a href="http://www.kernel.org" rel="noreferrer" target="_blank">www.kernel.org</a><br>

I don't fully understand what you are trying to do, but...<br>
<br>
<br>
<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><span class="">
1. I downloaded and extracted the source <a href="https://www.kernel.org/" rel="noreferrer" target="_blank">https://www.kernel.org/</a><br>
pub/linux/kernel/v4.x/linux-4.<wbr>4.32.tar.gz<br>
<br>
2. I ported the patches from to the latest source<br>
<br>
3. Built via the following commands<br>
<br></span>
1. make clean && make oldconfig && make prepare && make modules_prepare<br>
2. make modules -j8<br>

you don't need to rebuild the whole kernel, you can just compile the module in question against the currently running kernel. You will need the kernel-lt-devel and kernel-lt-headers packages installed.<span class=""><br>

I then copied the <module>.ko to /usr/lib/modules/4.4.32-1.e<br>
l7.elrepo.x86_64/kernel<br>
<br>
However, when attemp to load the module, I see<br>
<br>
[242683.114843] ip_gre: no symbol version for module_layout<br>
<br>
Is it because version 4.4.32-1.el7.elrepo.x86_64 is failing the check?<br>
Since elrepo has no SRPM's, how would one go about patching changes without<br>
building and installing the entire kernel from <a href="http://kernel.org" rel="noreferrer" target="_blank">kernel.org</a>?<br>

SRPMs are available here:<br>
<br>
<a href="http://elrepo.org/linux/kernel/el7/SRPMS/" rel="noreferrer" target="_blank">http://elrepo.org/linux/kernel<wbr>/el7/SRPMS/</a><br>
<br>
they are actually nosrc.rpm's (to save mirror space and bandwidth) so you'll also need to download the corresponding kernel source tarball from <a href="http://kernel.org" rel="noreferrer" target="_blank">kernel.org</a>, but otherwise contain everything you need to rebuild elrepo's kernel packages.<div class="HOEnZb"><div class="h5"><br>
