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.
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.
