Checkmk Werk 11116: job: Failed jobs are not OK just because a new one is running

by Moritz Kiemer

ID: 11116 Title: job: Failed jobs are not OK just because a new one is running Component: Checks & agents Level: 1 Class: Bug fix Version: 2.0.0i1 The job plugin determines its state from the age of the last job and its exit code. Previously, a job was considered {OK} regardless of its exit code whenever a job was running at the time of checking. This way a long running job could appear to be {OK} most of the time, even if it was constantly failing.

Checkmk Werk 11327: fileinfo.groups, filestats: enable additional rules for specific files in a file group

by Lisa Pichler

ID: 11327 Title: fileinfo.groups, filestats: enable additional rules for specific files in a file group Component: Checks & agents Level: 1 Class: New feature Version: 1.7.0i1 The plugins fileinfo.groups and filestats allow the user to monitor the size, age and count of a group of files on the Linux filesystem. With this extension, the rules for file size and age can be overwritten for specific files within a particular group. This can be done by defining a filename or a regular expression, and additional rules for those files. This functionality is optional and can be activated by checking the 'Additional rules for files' option in the "Size, age and count of file groups" and "Size, age and count of file groups (mk_filestats)" rulesets respectively.

Checkmk Werk 11499: Improve login session security

by Lars Michelsen

ID: 11499 Title: Improve login session security Component: Multisite Level: 1 Class: Security fix Version: 2.0.0i1 In previous Checkmk versions the login sessions were not tracked on the Checkmk server side. This means that a logout in the GUI was a pure client action destroying the authentication cookie. When the cookie was stored and reused later, the user was able to access the GUI again with that old login session which was logged out. This change extends the authentication cookie with a session ID which has to be known on the Checkmk server to result in a successful login. Once a login session is logging out from the GUI, the session is invalidated on the Checkmk server. If a client tries to access the GUI with an invalidated authentication cookie, the login will be rejected from now. Please note that we have added some limitations with this change: <ul> <li>Per user we can now have up to 20 parallel login sessions. Once a user account reaches the 21st sessions, the session with the longest inactivity will be invalidated.</li> <li>Existing sessions with an inactivity of more than 7 days will be invalidated.</li> </ul> The change of the authentication cookie requires all users to login again to the GUI after updating to Checkmk 2.0, because the cookie format is now incompatible with the authentication cookies issued by previous Checkmk versions. We use the incompatibility to switch the authentication cookie hashing algorithm from to sha256. The previous md5 at this point was not a security problem, but it can be considered bad practice.
