Enforce good santity checks with Mach messages sizes: 1) make sure Mach servers will not work on data beyond the end of the request message buffer. 2) make sure that on copying out the reply message buffer, we will not leak kernel data located after the buffer. 3) make sure that the server will not overwrite memory beyond the end of the reply message buffer. That check is the responsability of the server, there is just a DIAGNOSTIC test to check everything is in good shape. All currently implemented servers in NetBSD have been modified to check for this condition While we are here, build the mach services table (formerly in mach_namemap.c) and the services prototypes automatically from mach_services.master, just as this is done for system calls. The next step would be to fold the message formats in the mach_services.master file, but this tends to be difficult, as some messages are quite long and complex.

iTry to gather as much Mach services names as possible, this way we will have unimplemented services showing their names in ktrace Add a new generated file with only service id and name, which will be included by kdump to display services names. This removes the need for using the user ktrace facility for services names.

First work on Mach exceptions. Things that can turn into signals on UNIX may turn into exceptions on Mach: a small message sent by the kernel to the task that requested the exception. On Darwin, when an exception is sent, no signal can be delivered. TODO: more exceptions: arithmetic, bad instructions, emulation, s software, and syscalls (plain and Mach). There is also RPC alert, but I have no idea about what it is. While we are there, remove some user ktrace in notification code, and add a NODEF qualifier in mach_services.master: it will be used for notifications and exceptions, where the kernel is always client and never server: we don't want the message to be displayed as "unimplemented xxx" in kdump (thus UNIMPL is not good), but we don't want to generate the server prototype (therefore, STD is not good either). NODEF will declare it normally in the name tables without creating the prototype.
