From d83c6b3357d2230a4a8a315018e0b40560684392 Mon Sep 17 00:00:00 2001 From: Andreas Schneider Date: Thu, 17 Nov 2016 16:15:54 +0100 Subject: s4:torture: Fix cleanup of the secrets object in session_key test BUG: https://bugzilla.samba.org/show_bug.cgi?id=12433 The test is known to be failing if sealing is turned on in some circumstances. In this case a secret is created and then the function dcerpc_fetch_session_key() fails. The secret is not removed! We use torturesecret-%08x with random() to fill in the number. Sometimes it happens that random() returns a number we already used. So we end up trying to create a secret for an entry which already exists and run into a collision This change makes sure we always cleanup behind us and do not leave secret objects we created.
