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.")
Signed-off-by: Norman Maurer <redacted>

The patch LGTM, but please cc the blamed commit author in when you add
a 'Fixes' tag (me in this case ;)

Noted for the next time… 

Also please specify a target tree, either 'net' or 'net-next', in the
patch subj. Being declared as a fix, this should target 'net'.

Ok noted

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).

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.

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.

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 :)

Cheers,

Paolo
