Description Petr Menšík 2017-07-07 14:07:21 UTC
Description of problem:
IDN2 library will strip any underscores from give names

Version-Release number of selected component (if applicable):
libidn2-2.0.2-1.fc25.x86_64

How reproducible:
always

Steps to Reproduce:
1. idn2 _xmpp-server._tcp.domain.com
2.
3.

Actual results:
xmpp-server.tcp.domain.com

Expected results:
_xmpp-server._tcp.domain.com

Additional info:
Switched dnsmasq to libidn2 as bug #1449150. However regression was reported at https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=220521

Are SRV record supposed to be displayed in punnycode all the time?
Transitional mode does not help. idn command does not strip underscores.

Is there any known workaround or solution with libidn2?

Comment 1 Nikos Mavrogiannopoulos 2017-07-31 08:57:46 UTC
This was reported independently by the systemd maintainers as well upstream. The solution is to upgrade to 2.0.3 (thus added dependency on resolving this bug).

Comment 2 Robert Scheck 2017-07-31 10:07:15 UTC
Depends on https://gitlab.com/libidn/libidn2/issues/37 which was fixed
during the weekend AFAIK.

Comment 3 Nikos Mavrogiannopoulos 2017-07-31 10:47:44 UTC
I didn't realize that. However, ronn is available in fedora under rubygem-ronn (for some unknown reason).
