Piotr, In order for applications to support copy/paste across labels, the destination (paste) client must wait long enough for the selection manager to complete its mediation. We have modified various X11 toolkit libraries (Xview, Motif, GTK, StarOffice) to wait up to 120 seconds when TX is enabled. However, Firefox/Thunderbird is ignoring this setting. We haven't yet found out where/how to fix this.
Similarly, VirtualBox needs to be modified to wait 120 seconds when it is mediating operations between clients at different labels. Besides the double copy that you are using as a workaround, you can also get this to work if you can complete the confirmation in two seconds. That takes some practice, but it you have your pointer in the right place when the confirmation dialog pops up, you can verify that this is the problem. The selection manager can be configured to allow such operations without confirmation, in which case it should work automatically. However, that doesn't meet our security goals. --Glenn Piotr Jasiukajtis wrote: > Hi, > > It seems that copying and pasting (CTRL+C, CTRL+V) between zones in tjds > doesn't > work as expected when I try to paste something in Firefox. > > The workaround is to paste the selection in gnome-terminal or gedit and next > copy that into Firefox. > > It's 2008.11 101b. > I can't find related bug id. > >
