[User-mode-linux-devel] debugging proxy

[lars b. <la...@no...>]

I have hacked up a debugging proxy called ptproxy.  This program spawns
two processes.  Both are debugged by the proxy, and the debugging calls
made by one of the processes are redirected through the proxy to the other
process.

This is useful for the user-mode kernel, because it's debugging itself
to catch system calls.  This makes it impossible to directly attach a
debugger, because a process can only be debugged by one debugger at a
time.  With (an adaption of) ptproxy, the kernel can spawn a debugger
to debug itself.
