get rid of bogosities of the form "vm_maxsaddr + MAXSSIZ", and replace

them with USRSTACK. the former was a hack by wfj to accomodate his screwy
execve() implementation. the latter is a (minor) reversion to net/2.

fixs long broken 'dequeue' macro which would expand to 'dequeue_head' which

#define dequeue_head(queue) remqueue(queue, queue_first(queue))

according to andrew, the bit with the comment:

*is* necessary, so put it back in... it's in an #ifdef i386 part anyway.

vm_protect() of the user area is no longer required for i386 machines; the

protection is implemented by adjusting the bounds of the user segment
descriptors.

do the "right thing" with mmap protections, once and for all.
...
in particular, if an object is mapped private, DO NOT grant
VM_PROT_ALL protections to it; it could be sensitive data.

get rid of any support for vm_fault_wire() returning a result.

if it's going to be ifdef'd out until it's tested, it shouldn't
be put in to begin with.
also, minor ansifications and cleanups (mostly so tags would be happier).

Disallow access to the user pages, where the kernel stack is stored. This
...
is effected in useracc(), and also by a vm_protect() in vm_fork() for i386
CPUs. Without the latter a write to the user area, say USRSTACK+1000,
would hang a 386-based system.
1993-06-29 07:16:31 +00:00

ANSIfications. Added support for vm_fault_wire() returning a result; code
...
to actually fail is currently disabled, as this would enable some new code
in vm_map_pageable() (disabled in this commit) that hasn't been used to
date. I'm fairly confident it is all OK, but shall test it some more once
the rest of the kernel is more stable, before enabling it.
