Checkmk Werk 14925: Tighten permissions for Event Console pipe and sockets

ID: 14925 Title: Tighten permissions for Event Console pipe and sockets Component: Event Console Level: 1 Class: Bug fix Version: 2.2.0i1 For some internal communication of the <i>Event Console</i> Unix sockets are used. These reside in <tt>tmp/run/mkeventd/</tt> and used to be world readable. Since these sockets are not meant to be used from site external scripts and we cannot foresee the side-effects the permissions were changed so that only Checkmk can read and write to them. To make it easier to write custom events to the <i>Event Console</i> there is a Unix pipe also in <tt>tmp/run/mkeventd/</tt>. This pipe used to be world readable and writeable. With this Werk the permission is changed so that the Pipe is only world writeable. So custom scripts can still write events to this pipe but can no longer read from this pipe. If you used these sockets or pipe with custom scripts and rely on the previous permissions, you still can change them (eg. with <tt>chmod</tt>). Please be aware that we do not support this customization.
