On r352027 and later (tested up to r352054) running ping6 without parameters gives this error:
ping6: unable to limit access to system.dns service: Invalid argument
Same ping6 on r351925 works.
The problem is that r340363 (to libcasper) never got MFCed. oshogbo, is there a good reason not to MFC that change? If so, then I can fix ping6 to use the older casper strings.
ping6 also fails with the same message when called with parameters, tested on r352139
Alan I just merged all relevant things to stable/12.
I can confirm ping6 works for me now with userland from r352194. Unfortunately kernel from r352194 hangs at boot, see PR#240487

Thanks for the quick fix, oshogbo.
