Hello :) this patch series adds introspection and tracing facilities to the Hurd servers using libports. This isn't ready yet, but I'd like to give everyone a chance to complain early on. Some notes:
* I use Machs `Inherited Ports' mechanism to install a receive right at a well-known location to serve introspection requests. This is by choice orthogonal to the usual mechanism used in the Hurd, as I want it to be as universal as possible (e.g. I want to be able to use it on the proc server). * Servers can label port buckets and classes, and install a function that creates a human-readable description of an object. This information is then presented to the user doing portinfo --query-process, a feature that is hinted to by a #if 0ed option in portinfo.c. * rpctrace can now attach to cooperating servers that just relay messages to the tracing process. To that end, a footer is attached to the message to preserve original remote and local port, all rights are turned into mere names, and the msgt_deallocate flag is cleared so that out-of-band data isn't deallocated when we resend the message. * A new library, libintrospection, handles the introspection port registration and lookup, and the message wrapping/unwrapping. Flame on :) Justus
