812e4da7a8 New simple_lock code in asm: 
- s_lock_init()
 - s_lock()
 - s_lock_try()
 - s_unlock()

Created lock for IO APIC and apic_imen  (SMP version of imen)
 - imen_lock

Code to use imen_lock for access from apic_ipl.s and apic_vector.s.
Moved this code *outside* of mp_lock.

It seems to work!!!

360d4ad5ab Use setuid/seteuid around dangerous operations. Also a few buffer 
overflow patches that were "near" to where these operations are taking
place.  The buffer overflows are from OpenBSD.  The setuid/seteuid patches
are from NetBSD by way of OpenBSD (they changed them a little), at least from
my read of the tree.

This is the first of a series of OpenBSD lpr/et al merges.  It (and them)
should be merged back into 2.2 and/or 2.1 (if requested) branches when they
have been shaken out in -current.

b1ba015c25 Added a missing semicolon, compile failed when I turned on simple_lock(). 
Evidently this has never been compiled before, NOT a good sign...

c1f94e717b Well, consensus seems very split on this so I talked it over with DG 
and he says he's happy to see forward movement in aligning our defaults
with a 16 bit world, the 8 bit folk already being veterans by this
point who know how to use userconfig.

In any case, perhaps Warner will soon come to save us all with his Dynamic
Probing(tm) feature and this will all become totally moot in any case,
so it's probably not worth arguing about either way.

8b0597671f Quick and dirty (?) fix for noatime option. The WebNFS changes 
broke it by using the same value for MNT_EXPUBLIC as for MNT_NOATIME.
Just use a different value for MNT_EXPUBLIC.

9ecc3726d9 Fix a very stupid heap corruption bug: in ypproc_match_2_svc(), when 
we decide to do a DNS lookup, we NUL terminate the key string provided
by the client before passing it into the DNS lookup module. This is
actually wrong. Assume the key is 'foo.com'. In this case, key.keydat_val
will be "foo.com" and key.keydat_len will be 7 (seven characters; the
string is not NUL-terminated so it is not 8 as you might expect).
The string "foo.com" is actually allocated by the XDR routines when the
RPC request is decoded; exactly 7 bytes are allocated. By adding a NUL,
the string becomes "foo.com\0", but the '\0' goes into an 8th byte which
was never allocated for this string and which could be anywhere. The result
is that while the initial request may succeed, we could trash other
dynamically allocated structures (like, oh, I dunno, the circular map
cache queue?) and SEGV later. This is in fact what happens.

The fix is to copy the string into a larger local buffer and NUL-terminate
that buffer instead.
