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
An issue related to stringprep_nameprep and jabberd was reported in bug #1566414. Maybe one can explain the other.
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? https://koji.fedoraproject.org/koji/taskinfo?taskID=26729407 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.
libidn-1.34-2.fc27 has been submitted as an update to Fedora 27. https://bodhi.fedoraproject.org/updates/FEDORA-2018-25d5c86330
libidn-1.34-2.fc28 has been submitted as an update to Fedora 28. https://bodhi.fedoraproject.org/updates/FEDORA-2018-aae2d44488
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.
