Commit 5907b6cbb5c724f9729da59a644271b4258d122e started to handle Lock/Unlock events from Session at VDAgent. Although that works just fine, it does not cover all the situations as pointed by Andrei at [0] and I quote: > It fails for next test-case: > > * Connect with RV to VM > * Lock VM (ctrl-alt-del) > * Close RV > * Connect with RV to the VM again > * Do not unlock session. DnD files from client to locked VM. > > Result : Files are copied to VM. [0] https://bugzilla.redhat.com/show_bug.cgi?id=1323628#c6 To solve this situation, we need VDService to inform VDAgent if Session is Locked or not upon its initialization.
