RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Fixed In Version: 389-ds-base-1.3.1.5-1.el7
Doc Type: Bug Fix
Doc Text:
Cause: The sorted array of values in each attribute was not being stored and cleaned up correctly during add/modify operations. This introduced a memory corruption. Consequence: The server would crash during certain add or modify operations. Fix: Ensure the sorted list of attributes is properly freed when being updated. Result: The server does not crash during certain add or modify operations.

Description Scott Poore 2013-07-23 23:40:42 UTC 
Description of problem:

During ipa-replica-install, I'm seeing a segfault of slapd:

Jul 23 17:16:03 ipaqa64vmh kernel: [ 1909.707658] ns-slapd[18877]: segfault at 7f62cc003a10 ip 00007f5fd92c3693 sp 00007f5fa8ff45c0 error 4 in libslapd.so.0.0.0[7f5fd9203000+101000]

From Rich:

this looks like a crash in the new valueset code:

#0  0x00007f5fd92c3693 in valueset_find_sorted (a=0x7f5f6c0022a0,
     vs=vs@entry=0x7f5f6c0022d0, v=0x7f5f6c17f210,
     index=index@entry=0x7f5fa8ff461c) at ldap/servers/slapd/valueset.c:970
970            if ( (cmp = valueset_value_cmp(a, v,
vs->va[vs->sorted[mid]])) > 0)
(gdb) p vs->va
$1 = (struct slapi_value **) 0x7f5f6c003550
(gdb) p vs->va[0]
$2 = (struct slapi_value *) 0x7f5f6c17f050
(gdb) p vs->sorted
$3 = (int *) 0x7f5f6c17f360
(gdb) p mid
$4 = 0
(gdb) p vs->sorted[0]
$5 = 1811939480
(gdb) p *vs
$6 = {num = 1, max = 2, sorted = 0x7f5f6c17f360, va = 0x7f5f6c003550}

How reproducible:
always

Steps to Reproduce:
1.  Install IPA Master server
2.  Install IPA Replica


Actual results:
fails at end of ipa-replica-install with:

Global DNS configuration in LDAP server is empty
You can use 'dnsconfig-mod' command to set global DNS options that
would override settings in local named.conf files

Restarting the web server

Your system may be partly configured.
Run /usr/sbin/ipa-server-install --uninstall to clean up.

/usr/sbin/ipa-replica-install -U --setup-ca --setup-dns --forwarder=<DNSFORWARDER> -w <PASSWD> -p <PASSWD> /opt/rhqa_ipa/replica-info-<servername>.testrelm.com.gpg' (Expected 0, got 1)

In /var/log/messages you'll see a segfault like above.

Expected results:

Installs with no segfaults or crashdumps.

Comment 2 Rich Megginson 2013-07-23 23:44:56 UTC 
This isn't from a customer - what private data could this contain that we can't share?
Comment 3 Scott Poore 2013-07-24 01:36:37 UTC 
Created attachment 777540 [details]
abrt crash dump dir from slapd segfault public version

Attaching version of the abrt crash with some info scrubbed.  Unfortunately, this includes removed coredump file until I can confirm I am allowed to include it.  Hopefully, this helps make more of the problem public though.

Comment 6 Ján Rusnačko 2013-08-13 15:09:02 UTC 
Is it possible to automate outside of FreeIPA ? If so, please add steps to reproduce.

Comment 9 Rich Megginson 2013-10-01 23:23:58 UTC 
moving all ON_QA bugs to MODIFIED in order to add them to the errata (can't add bugs in the ON_QA state to an errata).  When the errata is created, the bugs should be automatically moved back to ON_QA.
