Description Jiří Dostál 2018-04-12 09:19:05 UTC 
Description of problem:
When using newest version on libdn-1.34-1, failure when trying to stringprer occurs for certain domain names. Reproduced when using jabberd from Spacewalk on Fedora 28 - jabberd is unable to start due to this regression. From libidn-1.33 and older it works as expected. 

Version-Release number of selected component (if applicable):
libidn-1.34-1.fc28.x86_64

How reproducible:
100%

Steps to Reproduce:
1. Install Spacewalk on Fedora 28
2. Check jabberd status
Alternatively:
1. It should be enough to stringprep hostname as all tested environment had this hostname format
   xxx-xx1.xxxx.xxx.xxx.xxx.com

Actual results:
Cannot stringprep hostname, which blocks whole Spacewalk to start

Expected results:
Same behavior as in 1.33 and lower - stringprep should pass.

Additional info:
I'll provide more information if you give me some pointers.
Comment 1 Miroslav Lichvar 2018-04-12 16:05:19 UTC 
Can you please provide a specific example of the stringprep() call that fails?
Comment 2 Jiří Dostál 2018-04-17 12:01:23 UTC

Comment 4 Miroslav Lichvar 2018-04-18 08:43:08 UTC 
I cannot reproduce it. stringprep_nameprep() from libidn-1.34 returns 0 for the given input here.
Comment 5 Miroslav Lichvar 2018-05-02 16:00:15 UTC 
This might be caused by an ABI break of libidn. Can you please try the test package from bug #1573961?
Comment 6 Miroslav Lichvar 2018-05-02 16:02:03 UTC 
An F28 build of the test package is here:

Comment 7 Jiří Dostál 2018-05-03 12:40:05 UTC 
I will test it and provide more information. Thank you!
Comment 8 Jiří Dostál 2018-05-03 12:49:06 UTC 
I've done some investigation and I can confirm that provided package works like a charm. Do you think it would be possible to come up with package that has this fixed? Unfortunately, Fedora 27 is affected the same way.
