Description Raúl 2019-09-09 08:25:04 UTC 
On r352027 and later (tested up to r352054) running ping6 without parameters gives this error:

[....]
# ping6
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.
Comment 4 wolfgang 2019-09-11 06:56:44 UTC 
I can confirm ping6 works for me now with userland from r352194. Unfortunately kernel from r352194 hangs at boot, see PR#240487
