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.

Description Kaushik Banerjee 2014-01-17 07:37:56 UTC 
Description of problem:
Internal error in domain log for large id numbers

Version-Release number of selected component (if applicable):
1.11.2-24.el7

How reproducible:
Occasionally

Steps to Reproduce:
1. Join sssd to the AD Server via realmd tool.
2. I see the message in domain logs with starting up sssd. Don't have the exact reproducer right now.

Jakub, since you were able to access my system and submit patches, do you also have a reproducer?

Actual results:
(Thu Jan 16 14:52:06 2014) [sssd[be[sssdad.com]]] [be_get_account_info] (0x0100): Got request for [4097][1][idnumber=4294967295]
(Thu Jan 16 14:52:06 2014) [sssd[be[sssdad.com]]] [be_req_set_domain] (0x0400): Changing request domain from [sssdad.com] to [sssdad.com]

(Thu Jan 16 14:52:06 2014) [sssd[be[sssdad.com]]] [acctinfo_callback] (0x0100): Request processed. Returned 3,5,Internal Error (Memory buffer error)

Expected results:


Additional info:
Comment 2 Jakub Hrozek 2014-01-17 10:19:16 UTC 
To reproduce, it should be enough to do:
getent passwd 4294967295

On an AD client. The bug shouldn't abort the request completely, the function that errored out was an optimization.

Comment 6 Kaushik Banerjee 2014-01-22 06:11:33 UTC 
I still see internal error in the logs. Shouldn't the internal error go away with the fix?

# getent passwd 4294967295
# echo $?
2

Comment 7 Jakub Hrozek 2014-01-23 21:22:18 UTC 
You're right, the internal error should go away. I reproduced the bug now and I see the error message is coming from a different location now -- so the request goes through (previously it just aborted) but returns with an unexpected combination of error codes. I'll look further.
Comment 8 Jakub Hrozek 2014-01-23 21:49:38 UTC 
OK, I have a patch now, we fail further calling the same function. Feel free to mark this bug as ASSIGNED.
Comment 9 Kaushik Banerjee 2014-01-24 07:27:15 UTC 
Re-opening this bug to have another fix for the internal error. Tested with version 1.11.2-29.el7
