Title: mssql_backup: Fixed missing default levels
Component: Checks & agents
Level: 2
Class: Bug fix
Version: 1.6.0i1
Werk 6143 removed the empty default levels. The consequence was that
all passive checks were gone because the default levels variable name
was unknown to Check_MK und therefore the autochecks could not be read.
This was introduced in Check_MK version in 1.5.0b8.

Title: Fix possible activation warning message about /etc/ssl/certs/localhost.crt certificate
Component: WATO
Level: 1
Class: Bug fix
Version: 1.5.0b9
During configuration activation the "trusted certificates file" var/ssl/ca-certificates.crt is
computed based on the configured global settings. In case the system certificates are trusted
all certificates in /etc/ssl/certs are read.
We found several RH/CentOS distros to have a /etc/ssl/certs/localhost.crt which seems to be some
kind of default certificate for local servers. The files may have a permission of 600 which makes
it not readable for the site user.
This results in an activation warning like this: ca-certificates: Failed to add certificate
'/etc/ssl/certs/localhost.crt' to trusted CA certificates. See web.log for details and these
entries in the var/log/web.log:
2018-06-21 03:55:52,120 [40] [cmk.web 19066] /master/check_mk/wato.py Internal error: Traceback (most recent call last):
File "/omd/sites/master/share/check_mk/web/htdocs/watolib.py", line 501, in _get_system_wide_trusted_ca_certificates
trusted_cas.update(self._get_certificates_from_file(os.path.join(cert_path, entry)))
File "/omd/sites/master/share/check_mk/web/htdocs/watolib.py", line 514, in _get_certificates_from_file
return [ match.group(0) for match in self._PEM_RE.finditer(open(path).read()) ]
IOError: [Errno 13] Permission denied: '/etc/ssl/certs/localhost.crt'
Because this may be a standard configuration and affect a lot of users we decided to remove this
warning for the /etc/ssl/certs/localhost.crt.
In case you need this /etc/ssl/certs/localhost.crt to be added to the trusted CA certificates
simply chown it to 644. It is a public certificate and not a secret.

Title: Fixed stale services on cluster nodes
Component: Core & setup
Level: 2
Class: Bug fix
Version: 1.6.0i1
When using Check_MK clusters it could happen that some of the services
on a node went stale and remained in this state. In this situation you
can find multiple messages in the cmc.log when using the CEE:
2018-07-21 12:47:52 [5] [Check_MK helper 4644] started, commandline: /omd/sites/beta/bin/cmk --keepalive
2018-07-21 12:48:42 [2] [Check_MK helper 4644] ignoring check result for lxclu1 / Filesystem /boot: no such service
2018-07-21 12:48:43 [4] [Check_MK helper 4644] restarting dead helper
2018-07-21 12:48:43 [5] [Check_MK helper 4644] exited normally
The issue was triggered because the cluster nodes reported service check
results for services which are assigned to the cluster using the "Clustered
services" rule set.
The problem could only happen when services of one check type were assigned to
the cluster and the cluster node. For example in case you have at least one
Filesystem service assigned to the node and at least one Filesystem service
assigned to the cluster.
This regression was introduced with 1.5.0b7 (Werk #5814).

Title: Fixed broken checking of unrelated hosts when using manual checks
Component: Core & setup
Level: 1
Class: Bug fix
Version: 1.6.0i1
When using the Check_MK Raw Edition it could happen that configuring manual
checks for a host broke the check execution of unrelated hosts.
The configuration of the manual check of all hosts was loaded into the context
of such an unrelated host. Because a host only loads the check definitions of
the checks it needs during checking, those manual check configurations were
trying to access unavailable data. This lead to a crash and a "(null)" output
shown for the "Check_MK" service.

Title: Fixed not working "manual checks" in Check_MK Raw Edition
Component: Core & setup
Level: 1
Class: Bug fix
Version: 1.6.0i1
Manual checks, often used for "process checks" were not executed
when using the Check_MK Raw Edition. All configured manual checks
became stale after some time and were never checked.
