RPM for the kernel samples?

RPM for the kernel samples?

[Jesse Brandeburg]

Hi there, does anyone here know if the samples/bpf directory from the 
kernel is built as a part of an RPM from fedora or RHEL/Centos?

In my searching I've not found anything.

I do know:
1) other directories/tooling in the kernel is already packaged as 
standalone RPMs
	a) see kernel-tools package which packages cpupower/turbostat
	b) the spec file would be substantially the same as the above
2) The tools/bpf directory already seems built as an RPM.
3) This seems very possible.

Does anyone know why I couldn't / shouldn't submit a request to Fedora 
to do this? I might even get the .spec file working myself just to prove 
the idea and give a sample?

Thanks!

It's certainly possible to build it from the existing kernel .spec file:

https://src.fedoraproject.org/rpms/kernel/blob/rawhide/f/kernel.spec#_1046

I know we have this available as an internal package for RHEL, but I
don't think we ship it anywhere. And it seems like the flag is turned
off for Fedora as well.

What do you need it for? Opening an issue asking for it to be built for
Fedora might be a good start; feel free to Cc me on that as well :)

Hi Toke! thanks!

I'm tired of fighting tooth and nail to get the samples compiled on my 
own system whenever I need them. I'd much rather there just be an 
already made set of executables.

We use them for testing our driver's functionality for XDP, among other 
things.

I'll file a bugzilla.

Right, makes sense. FYI we were discussing moving (some of?) the XDP
samples to xdp-tools[0].

I don't suppose you have anyone interested in working on an actual XDP
test suite of some kind, would you? Like a set of "compliance tests"
that lives in-tree and that any driver author can run to test their
driver's XDP implementation?

Great!

Not a bad idea, as long as compilation and use gets easier.

Good idea! I'll ask around ;-)
