Bug ID: 255316
Summary: Use of a Link-local address in resolv.conf does not
work
Product: Base System
Version: 13.0-RELEASE
Hardware: Any
OS: Any
Status: New
Severity: Affects Some People
Priority: ---
Component: bin
Assignee: b...@freebsd.org
Reporter: bc...@lafn.org

Suggested Patch
If /etc/resolv.conf has a link-local IPv6 address for the DNS server, then host
does not function even though ping works properly. I have traced the problem
to /usr/src/contrib/unbound/libunbound/libunbound.c where the test for valid
characters does not accept the % or some of the following characters.
I have attached a patch which I believe resolves the problem, but am unable to
test it in the system as I was not able to figure out how to build host with
the updated file. I am also not confident that there are other places that use
that lib that cannot handle the link-local addresses.
