Re: [Samba] Can I update our CIFS kernel module to support SMB 2.1/3 in RHEL/CentOS 6.x?

Thanks for the feedback. It does seem to be problematic to recompile the newer code against the older kernel code. I assumed most or all of the kernel APIs used by Samba would have been the same, but hadn't thought about changes to debugging calls. Also, upgrading only the kernel to a new major version without recompiling the myriad packages sitting on top could have similar results.

After sending my original post, I discovered my company had already deployed some CentOS 7 servers in a cloud farm. This makes it much easier to request additional hosts for this project, so it looks like we'll be taking the full upgrade route.

At my company we run server farms based on RHEL/CentOS 6.x and are nowhere near our EOL on those servers yet.  So upgrading them to run RHEL/CentOS 7 in order to gain SMB 2/3 support (since SMB 1 has recently been disabled) is a difficult path for us to take at the present time.

Is it possible to acquire an updated cifs.ko kernel driver that supports SMB 2.1+ or 3 and install and use that module with our existing RHEL/CentOS 6.x server installations?
