Summary 0000662: forcedeth driver no longer compiles against RHEL/CentOS/SL 7.2
Description You can see that others have discovered that the forcedeth driver no longer compiles against RHEL 7 variants:

http://comments.gmane.org/gmane.linux.rpm.elrepo.user/1706 [^]

I looked into it, and created a possible patch for this. I am not an expert, but the macros I replaced seem logical - apologies if it was daft. I attach the patch to this report.

I successfully built the driver against Scientific Linux 7.2, and was able to add this kmod driver to a modified anaconda kernel driver tree, and kickstart-ed an old Sun node with this network interface.

Many thanks for the patch.

For info, the two fixes are from upstream:

https://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/commit/drivers/net/ethernet/nvidia/forcedeth.c?h=v4.6.2&id=57a7744e09867ebcfa0ccf1d6d529caa7728d552 [^]


https://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/commit/drivers/net/ethernet/nvidia/forcedeth.c?h=v4.6.2&id=df8a39defad46b83694ea6dd868d332976d62cc0 [^]

but please don't bump the driver version unless upstream bump it.

Can you confirm if the current elrepo package works on el7.2? I am able to install the package and it weak links against RHEL7.2 kernels. I am also able to load the module with modprobe (no errors in dmesg, module loaded), but do not have the hardware to test.

IOW, is there a case for the driver to be rebuilt against RHEL7.2 or is it working as expected at present?

I brought up a lights-out interface on the test node, brought down the network, rmmod-ed the driver, yum-erased my kmod driver and yum-installed locally the elrepo driver. On a reboot the node came up on the network.

So yes, the elrepo driver works on SL 7.2 nodes. The only reason I tried to compile my own was to create a custom 7.2 anaconda kickstart environment, and of course to verify that I could build it with the anaconda kernel without any broken symbols, and no depmod issues. We have 21 Sun thumpers with NVIDIA MCP55 Ethernet interfaces that I may need to update to SL7 in the near future.

So this is just a data point - no need to change the existing elrepo driver.

cheers, etc.
