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.

GSSAPITest.java

In the attempt to boost jre performance (bug#831734), kerberos JAAS is broken.

It causes SIGSEGV when trying to authenticate.

Attached a sample program to reproduce, logs.

Comment 5 Alon Bar-Lev 2013-01-28 16:36:55 UTC 
Workaround: Revert to the default java security provider.
Comment 7 Alon Bar-Lev 2013-01-28 16:46:54 UTC 
Unrelated note:

Settings of jvm should be the defaults of openjdk settings.

Applications/administrators that wish to boost their performance can actively load security provider of their choice.

Changing the system width configuration of jvm and effecting all applications should have been avoided.
Comment 8 Andrew John Hughes 2013-01-29 18:21:55 UTC 
It seems the TCK doesn't really test non-block ciphers throughly.  The fix is fairly trivial; just a state that wasn't fully accounted for.

Comment 10 Deepak Bhole 2013-01-29 18:25:13 UTC 
We have reverted the errata which should make RHEV work again (with the version in 6.3.z/older 6.4 composes).

Revised patch that checks blockBuffer rather than blockBufferLen

It turns out some TCK tests started failing because there are valid cases with an empty block buffer.  So we test for the actual failure case (no blockBuffer at all) rather than trying to be clever.

Comment 24 Barak 2013-05-30 13:08:53 UTC 
Replacing the openJdk rpm on a 6.4 host with a 6.5 build might create a lot of none relevant noise.

However if we get a 6.4 (somwhat stable build) we can give it a quick test.

BTW the right way to test it is:

1. install vanilla rhel-XXX
   - make sure the new openJdk is installed
2. install ovirt-engine
3. join a domain
4. login
