16e3fbd2c1 Suser() simplification:
1:
  s/suser/suser_xxx/

2:
  Add new function: suser(struct proc *), prototyped in <sys/proc.h>.

3:
  s/suser_xxx(\([a-zA-Z0-9_]*\)->p_ucred, \&\1->p_acflag)/suser(\1)/

The remaining suser_xxx() calls will be scrutinized and dealt with
later.

There may be some unneeded #include <sys/cred.h>, but they are left
as an exercise for Bruce.

More changes to the suser() API will come along with the "jail" code.

833655c307 1) Fix our view of how ibcs2_semid_ds looks. There is no padding int there
(SVR4 does have it so that;s probably the cause of this bug)
2) Add a wrapper function for translation between ibcs2_ipc_perm and
ipc_perm as I think we screwed up when defining the ipc_perm struct and
mixed up 'normal' and creator [ug]id's
3) Fix IBCS2_IPC_STAT semctl. The FreeBSD version needs a union semun
whereas the IBCS2 version gives a struct ibcs2_semid_ds.

Apparently this is all fixed in the SVR4 compatibility code.

cea2b66bfe Can't use elf_brand_inuse() here because iBCS2 doesn't use ELF. D'oh!

7b9dc76b76 Removed the cast to a pointer in the definition of PS_STRINGS and
adjusted related casts to match (only in the kernel in this commit).
The pointer was only wanted in one place in kern_exec.c.  Applications
should use the kern.ps_strings sysctl instead of PS_STRINGS, so they
shouldn't notice this change.

982e80577d Examine all occurrences of sprintf(), strcat(), and str[n]cpy()
for possible buffer overflow problems. Replaced most sprintf()'s
with snprintf(); for others cases, added terminating NUL bytes where
appropriate, replaced constants like "16" with sizeof(), etc.

These changes include several bug fixes, but most changes are for
maintainability's sake. Any instance where it wasn't "immediately
obvious" that a buffer overflow could not occur was made safer.

464de37ce6 *gulp*. Jordan specifically OK'ed this..
This is the bulk of the support for doing kld modules.  Two linker_sets
were replaced by SYSINIT()'s.  VFS's and exec handlers are self registered.
kld is now a superset of lkm.  I have converted most of them, they will
follow as a seperate commit as samples.
This all still works as a static a.out kernel using LKM's.

3defb6d13f Fixed two potentially serious classes of bugs:
1) The vnode pager wasn't properly tracking the file size due to
   "size" being page rounded in some cases and not in others.
   This sometimes resulted in corrupted files. First noticed by
   Terry Lambert.
   Fixed by changing the "size" pager_alloc parameter to be a 64bit
   byte value (as opposed to a 32bit page index) and changing the
   pagers and their callers to deal with this properly.
2) Fixed a bogus type cast in round_page() and trunc_page() that
   caused some 64bit offsets and sizes to be scrambled. Removing
   the cast required adding casts at a few dozen callers.
   There may be problems with other bogus casts in close-by
   macros. A quick check seemed to indicate that those were okay,
   however.

70bb8503aa Add provisions for variant core dump file formats, depending on the
object format of the executable being dumped.  This is the first
step toward producing ELF core dumps in the proper format.  I will
commit the code to generate the ELF core dumps Real Soon Now.  In
the meantime, ELF executables won't dump core at all.  That is
probably no less useful than dumping a.out-style core dumps as they
have done until now.

a8d8e4f36a Backed out previous commit. The seconds part of microtime() is
not the necessarily the same as the seconds part of getmicrotime()
yet, and anyway, we should have used `time_second' if we only wanted
a sloppy value for the seconds part.  There is no point in making
ibcs2's time(2) more efficient than FreeBSD's time(3).

1d5f38ac22 This commit fixes various 64bit portability problems required for
FreeBSD/alpha.  The most significant item is to change the command
argument to ioctl functions from int to u_long.  This change brings us
inline with various other BSD versions.  Driver writers may like to
use (__FreeBSD_version == 300003) to detect this change.

The prototype FreeBSD/alpha machdep will follow in a couple of days
time.

4c8218a5c7 Move the "retval" (3rd) parameter from all syscall functions and put
it in struct proc instead.

This fixes a boatload of compiler warning, and removes a lot of cruft
from the sources.

I have not removed the /*ARGSUSED*/, they will require some looking at.

libkvm, ps and other userland struct proc frobbing programs will need
recompiled.

e64b1984f9 Change the M_NAMEI allocations to use the zone allocator. This change
plus the previous changes to use the zone allocator decrease the useage
of malloc by half.  The Zone allocator will be upgradeable to be able
to use per CPU-pools, and has more intelligent usage of SPLs.  Additionally,
it has reasonable stats gathering capabilities, while making most calls
inline.

c978fb3652 Fixed type mismatches for functions with args of type vm_prot_t and/or
vm_inherit_t.  These types are smaller than ints, so the prototypes
should have used the promoted type (int) to match the old-style function
definitions.  They use just vm_prot_t and/or vm_inherit_t.  This depends
on gcc features to work.  I fixed the definitions since this is easiest.
The correct fix may be to change the small types to u_int, to optimize
for time instead of space.

c756cf9cdf Do The Right Thing when an iBCS2 program does getgroups(0, whatever) -- we
were returning EFAULT, when it is a completely acceptable thing to do.
Also, at the same time, be a *bit* optimizing and don't allocate any
"stackgrap" memory if we're not going to use it.

This is another Oracle-discovered problem.

5bb5b9c674 For the xenix_ftime() routine, don't use the native version of the struct --
the XENIX version is packed, and two bytes smaller than ours.  So, define
the structure, and have it packed.  I used the __attribte__((packed))
modifier for this; I could also have surrounded the struct definition with
#pragma pack(2) -- but that would have meant making ibcs2_timeb's definition
outside the function.  This may need to be revisited if we ever want to
compile with a compiler other than gcc.  (I also used 'unsigned long'
instead of 'time_t' because I am writing to match an external specification
-- and the definition of time_t could change.)

61955ab830 Fully implement vfork. Vfork is now much much faster than even our
fork. (On my machine, fork is about 240usecs, vfork is 78usecs.)

Implement rfork(!RFPROC !RFMEM), which allows a thread to divorce its memory
	from the other threads of a group.

Implement rfork(!RFPROC RFCFDG), which closes all file descriptors, eliminating
	possible existing shares with other threads/processes.

Implement rfork(!RFPROC RFFDG), which divorces the file descriptors for a

Fix the case where a thread does an exec.  It is almost nonsense for a thread
	to modify the other threads address space by an exec, so we
	now automatically divorce the address space before modifying it.
