[Bug 1812744] [NEW] resolved uses only per-link dns servers

[Julian Andres Klode]

Public bug reported:

I configured multiple DNS servers in the DNS= option. The manual page
says:

"DNS requests are sent to one of the listed DNS servers in parallel to
suitable per-link DNS servers"

What I see however, is that each DNS request is sent twice to the same
server, e.g.:


connect(15, {sa_family=AF_INET, sin_port=htons(53), sin_addr=inet_addr("192.168.0.1")}, 16) = 0
connect(16, {sa_family=AF_INET, sin_port=htons(53), sin_addr=inet_addr("192.168.0.1")}, 16) = 0

If a per-link server is pushed by network-manager, it's always that one.
Since my per-link server can lag a lot, that is annoying.
