Dear all,

I would like to perform some cleanup operations after l4linux shuts down..such 
as zero out all the memory it used and re-encrypt the original vmlinux image. I 
would like to know how I could do this from sigma0 preferably or even in the 
fiasco kernel. Could anyone point me to where the clean up procedure (release 
of resources) occurs once l4linux shuts down?


I fear that Sigma0 does not care about any entry or exit of l4linux. What about doing this in the Moe config script instead? Have a 
look into the x86-fb.cfg example where the exit of a task is caught like this:


e = l:start({ caps = {
... );
print(ex_fb_spectrum exited with:  .. e:wait());

In addition you could do the housekeeping stuff there.
