OK thanks.
Two more security questions:
1. Has the lcall vulnerability been fixed? By a change in the mainline kernel?
2. I read on some mailing list (not this one) that in tt mode, processes within
a UML instance can read and write to each other's memory! Ah, here we are,
from last year:
http://www.paul.sladen.org/vserver/archives/200305/0074.html
Is this true, or just a rumour?
I have a security proposal to post next, but first I want to understand the
current state of play of UML security.
