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: tang-6-2.el7
Doc Type: Bug Fix
Doc Text:
.Tang reliably updates its cache When the Tang application generates its keys, for example, at first installation, Tang updates its cache. Previously, this process was unreliable, and the application cache did not update correctly to reflect Tang keys. This caused problems with using a Tang pin in Clevis, with the client displaying the error message `Key derivation key not available`. With this update, key generation and cache update logic was moved to Tang, removing the file watching dependency. As a result, the application cache remains in a correct state after cache update.

Description Martin Zelený 2019-04-26 12:45:40 UTC 
Cloning bug also for RHEL-7.7. Found by TR#357809 (BaseOS / Tier 1 / Security / RHEL7.7 on RHEL-7.7-20190424.0 / Alpha-1.0). Observed only on s390x.

The clevis part is not fixed on RHEL-7.7 (no error message output).

+++ This bug was initially created as a clone of Bug #1679186 +++

This is the tang part of bug 1650246. The clevis part is already fixed, but the problem stays on tang side. It's connected with upstream issue "Using file watching to update /var/cache/tang is unreliable #23" [1]
