Support for UDP_GRO was added in the past but the implementation for
getsockopt was missed which did lead to an error when we tried to
retrieve the setting for UDP_GRO. This patch adds the missing switch
case for UDP_GRO
Fixes: e20cf8d3f1f7 ("udp: implement GRO for plain UDP sockets.")

The patch LGTM, but please cc the blamed commit author in when you add
a 'Fixes' tag (me in this case ;)
Also please specify a target tree, either 'net' or 'net-next', in the
patch subj. Being declared as a fix, this should target 'net'.
One thing you can do to simplifies the maintainer's life, would be post
a v2 with the correct tag (and ev. obsolete this patch in patchwork).
Side note: I personally think this is more a new feature (is adds
getsockopt support for UDP_GRO) than a fix, so I would not have added
the 'Fixes' tag and I would have targeted net-next, but it's just my
opinion.
Cheers,
Paolo

I am quite new to contribute patches to the kernel so I am not sure how I would “obsolete” this patch and make a v2. If you can give me some pointers I am happy to do so.

I see… For me it seemed more like a bug as I can’t think of a reason why only setsockopt should be supported for an option but not getsockopt. But it may be just my opinion :)

Well, I actually gave you a bad advice about fiddling with patchwork.
The autoritative documentation:
Documentation/networking/netdev-FAQ.rst
(inside the kernel tree) suggests to avoid it.
Just posting a v2 will suffice.
Thanks!

Friendly ping…
As this missing change was most likely an oversight in the original commit I do think it should go into 5.12 and subsequently stable as well. That’s also the reason why I didn’t send a v2 and changed the commit message / subject for the patch. For me it clearly is a bug and not a new feature.
Thanks

I have no strong opinion against that (sorry, I hoped that was clear in
my reply).
Please go ahead.

I agree that it should be added to net
If you do not see it here:
https://patchwork.kernel.org/project/netdevbpf/list/
you need to re-send and clearly mark it as [PATCH net]. Make sure it has
a Fixes tag.
