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]
