Thanks for the testing, sorry again for the breakage.
Will send the patch shortly (with sizeof(unsigned long long)

instead of

hard-coded 64). Hopefully, not too late.

'groups' is "long unsigned int" not "unsigned long long"

        long unsigned int groups = nladdr->nl_groups;

And nladdr->nl_groups is specified as "__u32"

So the size of the relevant bits is actually strictly 32-bit.

This makes also the "ULL" in your constant specification incorrect as
well.

I think, ULL is right - I did it to make shift for 32 well-defined.
(which in result has 32 bits set)

Oh right, my bad.
