(ITS#5527) slapd segfaults when using dynlist

[Pierre Paysant-Le Roux]

Adding those tree lines to the default slapd.conf causes a segfault when starting slapd :

moduleload dynlist
overlay dynlist
dynlist-attrset groupOfNames labeledURI member

slapd 2.4.7-6ubuntu3 on Ubuntu hardy

[Chuck Short (zulcss)]

I was able to confirm this and have a patch to fix.

Thanks

2.4.7-6ubuntu4.1 crashes with dynlists also...

[Chuck Short (zulcss)]

I have submitted a bug report upstream.

Thanks
chuck

[Howard Chu (hyc)]

I don't see a crash with stock 2.4.7 or 2.4.9. Please provide the actual slapd.conf used to reproduce this bug, and the stack trace for the crash.

[Anderson (amg1127)]

I think it's better to send my entire test base...

In order to reproduce the bug:

# Download my attachment and extract the BZIP archive on an existing folder '/home/amg1127'.
# "cd" to '/home/amg1127/ldap
# Create the database from the included LDIF by running './create-master-base.sh'
# Got a SIGSEGV
# Remove /home/amg1127/ldap folder and entire content within
# Extract the BZIP archive on that folder again
# Edit the file /home/amg1127/ldap/maindb-commonparams.conf and comment lines 44-45
# Create the database from the included LDIF by running './create-master-base.sh'
# Edit the file /home/amg1127/ldap/maindb-commonparams.conf and uncomment lines 44-45 (that is, undo the previous edition).
# Run the server: './run-master-slapd.sh'
# Got another SIGSEGV

Thanks for this. I see it crashing in 2.4.7 but not in 2.4.9.

I just compiled openldap-2.4.9-1ubuntu1 and saw the bug fixed. It is now in production environment.

Are there plans to backport this package from Intrepid to Hardy?

[Adam Sommer (asommer)]

Justed tested openldap2.3 - 2.4.9-1ubuntu1~ppa1 from Chuck's PPA, and adding the dynlist configuration didn't cause slapd to segfault. Everything worked fine.

[Chuck Short (zulcss)]

This is in hardy-proposed now, please enable and test on a test machine since you are in a production environment already.

Thanks
chuck

[Anderson (amg1127)]

Sorry, I didn't saw your packages before, because of version numbering. I had installed packages from Chuck's PPA, with version 2.4.9-1ubuntu1~ppa1 and packages from hardy-proposed has version 2.4.9-0ubuntu0.8.04.

In order to allow automatic installation of hardy-proposed packages with a standard dist-upgrade, can version numbering be changed?

[Anderson (amg1127)]

I just installed them now... No crashes while starting services...

[Anderson (amg1127)]

I ran slapd with dynlist enabled since 20/06/2008 and stopped it yesterday (because of USN-625-1).

I think this bug can be closed now, but I didn't know if things were fixed in "pplr" setup...

[Chuck Short (zulcss)]

Closing thanks for the bug report.

[Pierre Paysant-Le Roux (pplr)]

Anderson, I tested the 2.4.9-0ubuntu0.8.04 and the bug is gone.
