Checkmk Werk 13091: Fixed event console time filters

by Sven Panne

ID: 13091 Title: Fixed event console time filters Component: Event Console Level: 2 Class: Bug fix Version: 2.1.0i1 The event console contains logic to quickly skip history files which are not relevant for a given query. This logic was broken from day one, often resulting in superfluous processing of irrelevant history files, which in turn could lead to e.g. timeouts in the GUI. This has been fixed now.

Checkmk Werk 13480: Veeam backup status: Ignore warning

by External contributor

ID: 13480 Title: Veeam backup status: Ignore warning Component: Checks & agents Level: 1 Class: Bug fix Version: 2.1.0i1 Since Veeam 10 <tt>Get-VBRJob</tt> returns a warning which ends up in the agent output and confuses the <tt>veeam_tapejobs</tt> check. This werk silently discards this warning and makes the check compatible with Veeam 10. Thanks to Marius Rieder.

Checkmk Werk 13509: Fix impossible host renaming if uninvolved sites have changes

by Ronny Bruska

ID: 13509 Title: Fix impossible host renaming if uninvolved sites have changes Component: Setup Level: 1 Class: Bug fix Version: 2.1.0i1 If a host was renamed on page "Properties of MYHOST" via "Hosts" - "Rename", the renaming operation was not possible if any site in distributed environment had pending changes. This leaded to situations where no more renaming was possible, e.g. if remote sites where continuous disabled. >From now on, only the central site and the site the renamed host is monitored on must have no pending changes.

Checkmk Werk 13479: Commandlets of active checks and special agents may be passed None as IP address

by Moritz Kiemer

ID: 13479 Title: Commandlets of active checks and special agents may be passed None as IP address Component: Checks & agents Level: 1 Class: New feature Version: 2.1.0i1 This werk only affects users who have implemented their own plugins for active checks or special agents (the ones commonly named <tt>checks/check_*</tt> and <tt>checks/agent_*</tt>). The functions implemented in those plugins have to a accept the IP address of the host as an argument. For hosts without an IP address they used to get passed <tt>"0.0.0.0"</tt> or <tt>"::0"</tt>. This has been changed to `None`. Since most of these functions simply pass it on in a list, this should not make any difference.

Checkmk Werk 13195: Add validation to Documentation URL

by Maximilian Wirtz

ID: 13195 Title: Add validation to Documentation URL Component: Setup Level: 1 Class: Security fix Version: 2.1.0i1 Previous to this Werk the URLs to Documentation were not validated (e.g. in the rule creation dialog). This could have lead to malicious links, e.g. links containing javascript. These links now will be validated. The URL schemes are now restricted to "http" and "https".

Checkmk Werk 13131: custom_files: Fix permissions of custom deployed agent plugins

by Andreas Umbreit

ID: 13131 Title: custom_files: Fix permissions of custom deployed agent plugins Component: agents Level: 1 Class: Bug fix Version: 2.1.0i1 This Werk fixes a regression that was introduced with Checkmk 2.0.0. Only agent installations that need to call agent plugins with a non-root user are affected. When deploying custom files with the "Deploy custom files with agent" agent rule, one would expect files placed under <tt>pkgname/lib/plugins/</tt> to be deployed as plugin files. This only partially held true before, because files placed under the <tt>plugins</tt> subfolder weren't recognized as actual plugins. While <tt>lib</tt> files are deployed with a permissions of <tt>0640</tt>, plugin files are to be deployed with permissions of <tt>0755</tt>, which was not done for custom deployed files. However, as the executable flag of all custom files is maintained during deployment, the plugins are (if placed as executable on the Checkmk site) still executable on the hosts, but without being accessible to non-root users. Hence, it was not possible to use the agent rule "Plugins, local checks and MRPE for non-root users" or other techniques that need to call plugins with a non-root user in combination with custom deployed plugin files. Files under <tt>pkgname/lib/plugins</tt> now are deployed permissions of <tt>0755</tt>, regardless of the initial permissions when placed at the custom files directory on the site.

Checkmk Werk 13132: mk_filestats: Deploy agent plugin without config

by Andreas Umbreit

ID: 13132 Title: mk_filestats: Deploy agent plugin without config Component: agents Level: 1 Class: Bug fix Version: 2.1.0i1 It's now possible to bake agents with agent rule "Count, size and age of files - mk_filestat (Linux)" while selecting "Deploy the filestats plugin without configuration. This fixes a regression introduced with Checkmk 2.0.0 that lead to a crash when baking agents.
