By "UML host" you mean the UML kernel itself, aka the "guest" kernel, right? Upgrading the host isn't needed (there are security problems which would suggest this, but that's another problem even because most are about local security - don't take my word on this).

Is Fedora applying exec-shield to all of their kernels now? Yes, for what I know (some recent Fedora removed one of their patches, maybe).

Although I hate > to have to disable it. Disabling it for UML only should be possible. Also: 1) Uml 2.6.11 should hopefully work even without disabling 2) if you can help a bit, maybe we can fix the issue. 3) I'm not even sure that it's exec-shield the exact problem - however, 2.6.8 is too old and bad (for UML) to do any debugging on it. -- Paolo Giarrusso, aka Blaisorblade Linux registered user n. 292729 http://www.user-mode-linux.org/~blaisorblade ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
