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.

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.

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.

cleanup.
* Require the file system to decide whether or not linking and unlinking of
directories is allowed, and disable it for all current file systems.

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.
