Last week:
* Committed a lot of documentation: cd to froggy/docs, make, and
point your browser at froggy/docs/html/book1.html. The docs are,
of course, a little back-level, but I'll try to keep them more or
less current.
* Added syscall entry filtering.
* Added userspace callbacks that correspond to all the utrace
reoprt_* callbacks.
* Added tests for all that in froggy/tests and demos/stracef.
* Started experimenting with attach_tree().
Next week(s):
* More work on attach_tree().
* Add stuff to limit user control of processes--right now, anyone
can attach, e.g., PID 1, init, and, like, stop it. Not good. I
think the thing to do might be to make it possible for non-root
users to attach to processes they don't have permissions for, but
only to monitor them, not to do anything that would change
anything about them. And it would probably be a good idea if even
root couldn't screw with init.
* Maybe start looking into incorporating breakpoints into froggy.
