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.

explorer a9ef8aef84 This fixes a nasty little bug where traceroute (and other raw-ip sending
programs which attach their own header) can crash the machine.  The problem
in this case was:
	a variable "space" was set to the total data to copy,
	len was used to remember how much to copy in this chunk (mbuf),
	in one case, len = min(MCLBYTES - max_hdr, resid) but
		size -= MCLBYTES;
	 instead of
		size -= len;

Note that userland programs can still crash the machine by providing
bogus data in the ip->ip_len field I suspect.  I haven't verified this,
but will soon be doing so and applying a fix of some sort.  Probably
clamping the ip->ip_len value to the true packet size will be ok.

cgd 1abc77f86d if kmem_malloc() fails while trying to allocate an mbuf cluster, try
and free some space by calling m_reclaim().  Also, log the "mb_map full"
error message (at most) every 60-seconds.  The old code would log it
once over the lifetime of the system, but that's not a useful diagnostic.
(More useful is the new behaviour, which roughly indicates how often
periods of heavy load occur, without spamming the console and system
logs with messages.)

jonathan e7ef034c05 Add NTP kernel precision timekeeping from Dave Mill's xntp distribution
and the "kernel.tar.Z" distribution on louie.udel.edu, which is older than
xntp 3.4y or 3.5a, but contains newer kernel source fragments.

This commit adds support for a new kernel configuration option, NTP.
If NTP is selected, then the system clock should be run at "HZ", which
must be defined at compile time to be one value from:
  60, 64, 100, 128, 256, 512, 1024.

Powers of 2 are ideal; 60 and 100 are supported but are marginally less
accurate.

If NTP is not configured, there should be no change in behavior relative
to pre-NTP kernels.

These changes have been tested extensively with xntpd 3.4y on a decstation;
almost identical kernel mods work on an i386.  No pulse-per-second (PPS)
line discipline support is included, due to unavailability of hardware
to test it.

With this in-kernel PLL support for NetBSD, both xntp 3.4y and xntp
3.5a user-level code need minor changes. xntp's prototype for
syscall() is  correct for FreeBSD, but not for NetBSD.

cgd c0cdc0cf04 when printing data modified on the free list:
(1) do not cast it to (void *), and
	(2) print it as 0x%x, rather than %p.
This is not perfect (because the data being printed is "int32_t"-sized), but
is more correct than printing it as a pointer because the data is _not_ a
pointer, it is data to be printed in hex, and on some systems, pointers are
wider than the data items being printed, which leads to excess and misleading
output.  The only 'right' solution to this is to have a printf specifier
that prints the fixed-sized types the right way, and that's not really
practical.

thorpej 5b39541e48 New generic disk framework. Highlights:
- New metrics handling.  Metrics are now kept in the new
	  `struct disk'.  Busy time is now stored as a timeval, and
	  transfer count in bytes.

	- Storage for disklabels is now dynamically allocated, so that
	  the size of the disk structure is not machine-dependent.

	- Several new functions for attaching and detaching disks, and
	  handling metrics calculation.

Old-style instrumentation is still supported in drivers that did it before.
However, old-style instrumentation is being deprecated, and will go away
once the userland utilities are updated for the new framework.

For usage and architectural details, see the forthcoming disk(9) manual
page.

int profil(char *, int, int, int), and new one is int profile(char *,
size_t, u_long, u_int).  the size_t is the size of the buffer,
and the u_long is the 'starting offset'.  (I changed the last int
to u_int, because it's treated as a u_int everywhere, and isn't

because it's async; bdwrite is also async), it still writes things
in-order, it makes sure the proper accountins is done (see the
wasdelayed cases in bwrite()), and it allows writes to vnodes on volumes
mountd with the MNT_ASYNC to be converted into delayed writes the way
God, err, Kirk intended.  Convert synchronous bwrite()s on MNT_ASYNC
file systems to delayed writes.
