Description Florian Weimer 2019-01-28 13:06:27 UTC 
The Linux kernel does not forward certain ICMP errors to userspace unless IP_RECVERR/IPV6_RECVERR is specified.  We should use this socket option in the DNS stub resolver, as suggested in the upstream bug.
Comment 1 Florian Weimer 2019-05-02 16:25:54 UTC 
We are not going to backport this further.
