Description Scott Baker 2018-05-02 15:21:13 UTC 
Description of problem:
Rebooted my Fedora 27 server and jabberd wouldn't start after. After some digging in the log files I found the following errors:

May  2 02:45:11 perturb c2s[5522]: /usr/bin/c2s: Symbol `stringprep_xmpp_nodeprep' has different size in shared object, consider re-linking
May  2 02:45:11 perturb c2s[5522]: /usr/bin/c2s: Symbol `stringprep_xmpp_resourceprep' has different size in shared object, consider re-linking
May  2 02:45:11 perturb c2s[5522]: /usr/bin/c2s: Symbol `stringprep_nameprep' has different size in shared object, consider re-linking
May  2 02:45:11 perturb s2s[5523]: /usr/bin/s2s: Symbol `stringprep_nameprep' has different size in shared object, consider re-linking
May  2 02:45:11 perturb sm[5524]: /usr/bin/sm: Symbol `stringprep_nameprep' has different size in shared object, consider re-linking

Some Googling told me that function is part of libidn. I did a "yum downgrade libidn" and it reverted to 1.33 and I was able to start jabberd again. I assume this is a libidn bug and not a jabberd bug? I might be wrong though.

Version-Release number of selected component (if applicable):
Works : libidn-1.33-4.fc27.x86_64
Broken: libidn-1.34-1.fc27.x86_64

How reproducible:
Easily

Steps to Reproduce:
1. Attempt to start jabberd with libidn-1.34
2. Note the failure
3. Profit
Comment 1 Miroslav Lichvar 2018-05-02 15:25:36 UTC 
An issue related to stringprep_nameprep and jabberd was reported in bug #1566414. Maybe one can explain the other.
Comment 2 Miroslav Lichvar 2018-05-02 15:59:20 UTC 
It looks like there was an ABI break in libidn-1.34 due to:
http://git.savannah.gnu.org/cgit/libidn.git/commit/?id=518b72c7273278d24cb79ac1485972e42cf98ed4

Could you please try the following test package, which reverts that change, and see if the problem disappears?

However, I'm not sure what should we do here. If some packages were already rebuilt with the new libidn, they will break if we revert that change back. I suspect we have the same problem in Fedora 28. libidn was updated to 1.34 after the F28 mass rebuild.

Comment 5 Scott Baker 2018-05-04 14:10:14 UTC 
I just installed libidn-1.34-2.fc28 and now jabberd *will* start. I'd live to give it a full day worth of testing before I saw for sure, but initially this looks like a good fix.
