chs ac3bc537bd eliminate the KERN_* error codes in favor of the traditional E* codes.
the mapping is:

KERN_SUCCESS			0
KERN_INVALID_ADDRESS		EFAULT
KERN_PROTECTION_FAILURE		EACCES
KERN_NO_SPACE			ENOMEM
KERN_INVALID_ARGUMENT		EINVAL
KERN_FAILURE			various, mostly turn into KASSERTs
KERN_RESOURCE_SHORTAGE		ENOMEM
KERN_NOT_RECEIVER		<unused>
KERN_NO_ACCESS			<unused>
KERN_PAGES_LOCKED		<unused>

thorpej e39f7bbe1c NBPG -> PAGE_SIZE 2000-11-14 22:16:38 +00:00
thorpej 72a24b4eae Add an align argument to uvm_map() and some callers of that
routine.  Works similarly fto pmap_prefer(), but allows callers
to specify a minimum power-of-two alignment of the region.
How we ever got along without this for so long is beyond me.

simonb da251cb08f Delete a couple of <uvm/uvm_extern.h> includes that were for
<sys/sysctl.h> only.

mrg 32aa199ccf remove include of <vm/vm.h> 2000-06-27 17:41:07 +00:00
simonb 38cc1b3975 Add new sysctl node "KERN_SYSVIPC_INFO" with "KERN_SYSVIPC_MSG_INFO",
"KERN_SYSVIPC_SEM_INFO" and "KERN_SYSVIPC_SHM_INFO" to return the
info and data structures for the relevent SysV IPC types.  The return
structures use fixed-size types and should be compat32 safe.  All
user-visible changes are protected with
	#if !defined(_POSIX_C_SOURCE) && !defined(_XOPEN_SOURCE)

Make all variable declarations extern in msg.h, sem.h and shm.h and
add relevent variable declarations to sysv_*.c and remove unneeded
header files from those .c files.

Make compat14 SysV IPC conversion functions and sysctl_file() static.

Change the data pointer to "void *" in sysctl_clockrate(),
sysctl_ntptime(), sysctl_file() and sysctl_doeproc().

simonb dd06794f0b Remove shmsegs declaration from conf/param.c - it doesn't belong here.
Instead, put it in kern/sysv_shm.c.

kleink 230876cf26 Merge parts of chs-ubc2 into the trunk:
* Remove the casts to vaddr_t from the round_page() and trunc_page() macros to
  make them type-generic, which is necessary i.e. to operate on file offsets
  without truncating them.
* In due course, cast pointer arguments to these macros to an appropriate
  integral type (paddr_t, vaddr_t).

Originally done by Chuck Silvers, updated by myself.

thorpej dc8ecaa15b Overhaul of the SVID IPC facilities, primarily to use the types specified
by the Single UNIX Specification version 2, rather than the SVR2-derived
types.  While I was here, I did a namespace sweep to expose the constants
and strucutures, and structure members described by SUSv2; documentation
updates coming shortly.

Fixes kern/8158.

mrg d2397ac5f7 completely remove Mach VM support. all that is left is the all the
header files as UVM still uses (most of) these.

mrg 1a8c7604f4 initial import of the new virtual memory system, UVM, into -current.
UVM was written by chuck cranor <chuck@maria.wustl.edu>, with some
minor portions derived from the old Mach code.  i provided some help
getting swap and paging working, and other bug fixes/ideas.  chuck
silvers <chuq@chuq.com> also provided some other fixes.

this is the rest of the MI portion changes.

this will be KNF'd shortly.  :-)

christos da17295d91 Calling shmdt(2) before calling shmat(2) would crash the system because
p->p_vmspace->vm_shm would be NULL. Protected the rest of the cases where
that might happen too. This was the reason why sunxdoom would panic the
system in SVR4 emulation.

cgd 3748c1aef7 try to insure that the 'default' address for shm segments is the same
from process to process.  It apparently is on SysV systems, and some
programs depend on this.  Suggested by  John Birrell <jb@werple.mira.net.au>.

for them. There are a few #ifdef COMPAT_XX remaining, but they are not easy
or worth eliminating (yet).

christos fb371ccef0 tty_tb.c: need to include ioctl_compat.h in order to compile.
sysv_shm.c: make shm_find_segment_by_shmid global so it can be used by

rest: Add #ifdef COMPAT_HPUX where needed
