e25e0c30e2 Warner gave a nice followup in email, and I thought it would be nice to
get it in the CVS logs.  This pertains to rev 1.30 (and the MFC of it):

  Space optimization forces the kernel to always use fragments to store
  parts of file, rather than using an entire block when less than an
  entire block has been written.  This forces files to be as small as
  they can be at the minor cost of time to do all the fussy stuff.  The
  cpio image that we put on the disk was so close to filling the disk
  exactly that this minor minor difference made a big difference.  The
  system changed things to time optmization on the first write.  When
  the end of file was hit, it tried to allocate a full block (4k), but
  there was only 3k left on the disk (since you get only 1407 blocks on
  a 1.44 floppy) so it failed.  So this change nails the space
  optmiziation in place for the whole operation.

8ce3f3dd28 Make it possible to use IP_TTL and IP_TOS setsockopt(2) options
on certain types of SOCK_RAW sockets.  Also, use the ip.ttl MIB
variable instead of MAXTTL constant as the default time-to-live
value for outgoing IP packets all over the place, as we already
do this for TCP and UDP.

5db078a9be Fix mtx_legal2block. The only time that it is bad to block on a mutex is
if we hold a spin mutex, since we can trivially get into deadlocks if we
start switching out of processes that hold spinlocks.  Checking to see if
interrupts were disabled was a sort of cheap way of doing this since most
of the time interrupts were only disabled when holding a spin lock.  At
least on the i386.  To fix this properly, use a per-process counter
p_spinlocks that counts the number of spin locks currently held, and
instead of checking to see if interrupts are disabled in the witness code,
check to see if we hold any spin locks.  Since child processes always
start up with the sched lock magically held in fork_exit(), we initialize
p_spinlocks to 1 for child processes.  Note that proc0 doesn't go through
fork_exit(), so it starts with no spin locks held.

ca5bd0c65a newfs with `-m 1'
This is needed even with `-o space' as the kernel decides to be "helpful"
and not really do space optimization.  Looking at src/sys/ufs/ffs/ffs_alloc.c
we see why:		if (fs->fs_minfree <= 5 ||
		            fs->fs_cstotal.cs_nffree >
		            (off_t)fs->fs_dsize * fs->fs_minfree / (2 * 100))
			            break;
	            log(LOG_NOTICE, "%s: optimization changed from SPACE to TIME\n"

I have picked `1' vs. `0' just incase some code somewhere has the assumption
the %free can never be `0'.

4bde2ac539 Fix is a similar race condition as existed in the mbuf code. When we go
into an interruptable sleep and we increment a sleep count, we make sure
that we are the thread that will decrement the count when we wakeup.
Otherwise, what happens is that if we get interrupted (signal) and we
have to wake up, but before we get our mutex, some thread that wants
to wake us up detects that the count is non-zero and so enters wakeup_one(),
but there's nothing on the sleep queue and so we don't get woken up. The
thread will still decrement the sleep count, which is bad because we will
also decrement it again later (as we got interrupted) and are already off
the sleep queue.

bfef7ed45c It was possible for ip_forward() to supply to icmp_error()
an IP header with ip_len in network byte order. For certain
values of ip_len, this could cause icmp_error() to write
beyond the end of an mbuf, causing mbuf free-list corruption.
This problem was observed during generation of ICMP redirects.

We now make quite sure that the copy of the IP header kept
for icmp_error() is stored in a non-shared mbuf header so
that it will not be modified by ip_output().

Also:
- Calculate the correct number of bytes that need to be
  retained for icmp_error(), instead of assuming that 64
  is enough (it's not).
- In icmp_error(), use m_copydata instead of bcopy() to
  copy from the supplied mbuf chain, in case the first 8
  bytes of IP payload are not stored directly after the IP
  header.
- Sanity-check ip_len in icmp_error(), and panic if it is
  less than sizeof(struct ip). Incoming packets with bad
  ip_len values are discarded in ip_input(), so this should
  only be triggered by bugs in the code, not by bad packets.

This patch results from code and suggestions from Ruslan, Bosko,
Jonathan Lemon and Matt Dillon, with important testing by Mike
Tancsa, who could reproduce this problem at will.

5af5ae6e18 Take the KINFO_PROC_SIZE back down to 912 on alpha.
Since the compiler lays out the stuct so that pointers are naturally
(8-byte) aligned aligned, adding the int ki_layout didn't change the size of
the stuct; it just converted the alignment padding to a usable struct
field.

We have been running this patch on a production NIS server for 2.5 weeks now.
Normally we would have ypserv die at least once a week, and often many times
a day.

This patch treats and error from select as zeroing out the FD_SET to indicate
that no fds are ready for reading.  This is safe because the rpc code
always re-inits the FDSET before calling select.

read its station address from the EEPROM automatically when reset,
so you don't need to program the filter if you want to keep using the
factory default address, but if you want to change it with "ifconfig vr0
ether xx:xx:xx:xx:xx:xx" then we need to manually set it in the init
routine.
