[User-mode-linux-devel] CVS checkins

[Jeff D. <jd...@ka...>]

I've made another batch of checkins.  They include:

the beginnings of the IA-64 port
the userspace access macros now do access checking properly
fixed a race early in the boot process caused by a SIGVTALRM hitting before 
the signal handler had been set up
put some checks in sys_ptrace to make sure that kernel memory can't be 
accessed through ptrace

And, as a bonus, I found a way to crash it that I don't know how to fix yet.  
So, if you've always wanted to panic a virtual machine but didn't know how, 
here's what you do:

boot it up with an extra virtual console or two
log in and run 'strace -f -p <pid>' with the pid of a getty running on a 
virtual console
log in on that console
you will probably get a nice kernel-mode fault

This seems to be somewhat dependent on what strace finds in some random memory 
that it's looking at, but this is reliable for me...
