truss on FreeBSD (was: procfs patches (fwd))

[Marc Slemko <ma...@znep.com>]

Cool.  truss for FreeBSD.  Very cool.  Nicer than ktrace.  Sometimes. 

(related in that ktrace is often a useful tool to figure out what broken
web things like Apache are doing...)

NT have anything similar?  Debuggers are fine, but they really are useful
in a different way.

Subject: procfs patches

These are the kernel side of the truss work I've been doing for the past
few years.  I'm running a 2.2 system with these patches.

The truss and procctl programs are at http://www.freebsd.org/~sef/truss --
it works, and even works for linux binaries.  (I'm working on even better
version, that will be able to print out the arguments in an intelligent
fashion, but that's nowhere near ready.)

Enjoy.  I expect to check this stuff in "soon" (hopefully within a couple of
weekends).  Note that you need to rebuild libkvm, ps, gdb, and all LKM's -- I
kinda paniced one of my systems when I forgot about that, and went multiuser
;).  Also note the new file -- sys/pioctl.h.
