Description of problem: When the jabberd service starts and authentication fails, s2s appears to segfault. Version-Release number of selected component (if applicable): jabberd-2.2.4-1.fc10.x86_64 How reproducible: Seems to be 100% Steps to Reproduce: 1. Install stock jabberd, service jabberd start. (everything is fine) 2. Modify the <secret> in /etc/jabberd/router-users.xml to anything you like. (it appears as a hash originally) 3. service jabberd restart Actual results: Service appears to start but quickly dies generating this in /var/log/messages: Mar 10 22:05:31 kramer jabberd/sm[17036]: attempting connection to router at 127.0.0.1, port=5347 Mar 10 22:05:31 kramer jabberd/router[17005]: [127.0.0.1, port=51704] connect Mar 10 22:05:31 kramer jabberd/sm[17036]: error from router: Authentication failed ((null)) Mar 10 22:05:31 kramer jabberd/sm[17036]: connection to router closed Mar 10 22:05:31 kramer jabberd/sm[17036]: shutting down Mar 10 22:05:31 kramer jabberd/router[17005]: [127.0.0.1, port=51704] disconnect Mar 10 22:05:31 kramer jabberd/c2s[17069]: attempting connection to router at 127.0.0.1, port=5347 Mar 10 22:05:31 kramer jabberd/router[17005]: [127.0.0.1, port=51705] connect Mar 10 22:05:31 kramer jabberd/c2s[17069]: error from router: Authentication failed ((null)) Mar 10 22:05:31 kramer jabberd/c2s[17069]: connection to router closed Mar 10 22:05:31 kramer jabberd/router[17005]: [127.0.0.1, port=51705] disconnect Mar 10 22:05:31 kramer jabberd/c2s[17069]: shutting down Mar 10 22:05:31 kramer jabberd/s2s[17100]: attempting connection to router at 127.0.0.1, port=5347 Mar 10 22:05:31 kramer jabberd/router[17005]: [127.0.0.1, port=51706] connect Mar 10 22:05:31 kramer jabberd/s2s[17100]: error from router: Authentication failed ((null)) Mar 10 22:05:31 kramer jabberd/s2s[17100]: connection to router closed Mar 10 22:05:31 kramer jabberd/router[17005]: [127.0.0.1, port=51706] disconnect Mar 10 22:05:31 kramer jabberd/s2s[17100]: shutting down Mar 10 22:05:31 kramer kernel: s2s[17100]: segfault at 243c9c0 ip 000000000243c9c0 sp 00007fff2ee493e8 error 15 Expected results: No segfault if authentication fails. Additional info: Originally discovered this in a Spacewalk bug which generated a more useful stack trace than this does, see bug #487618.
Can you please retest with 2.2.7.1 from rawhide? I could provide binaries build for F10 if needed.
I think I can test just have to find some time to spin up an F11 guest. Will try to do this sometime soon. Binaries for F10 if not much trouble would save me some time.
Confirmed with jabberd-2.2.7.1-1.fc10.i386.rpm. Edit the password in /etc/jabberd/router-users.xml, change it to anything.

The backtrace is not very helpful without the debug info. Please, install jabberd-debuginfo and run "gdb -p <pid>" on the s2s process. Also note: http://fedoraproject.org/wiki/StackTraces Anyway, it smells like an upstream bug, so I'd recommend filing it in Jabberd's trac too: http://jabberd2.xiaoka.com/
This message is a reminder that Fedora 10 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 10. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '10'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 10's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 10 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Fedora 10 changed to end-of-life (EOL) status on 2009-12-17. Fedora 10 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
