97d8d152c2 Introduce tcp_hostcache and remove the tcp specific metrics from
the routing table.  Move all usage and references in the tcp stack
from the routing table metrics to the tcp hostcache.

It caches measured parameters of past tcp sessions to provide better
initial start values for following connections from or to the same
source or destination.  Depending on the network parameters to/from
the remote host this can lead to significant speedups for new tcp
connections after the first one because they inherit and shortcut
the learning curve.

tcp_hostcache is designed for multiple concurrent access in SMP
environments with high contention and is hash indexed by remote
ip address.

It removes significant locking requirements from the tcp stack with
regard to the routing table.

26d02ca7ba Remove RTF_PRCLONING from routing table and adjust users of it
accordingly.  The define is left intact for ABI compatibility
with userland.

This is a pre-step for the introduction of tcp_hostcache.  The
network stack remains fully useable with this change.

1fc7ca0fb1 Set the ACPI processor Id in the PCPU structure so that CPU idling
on SMP systems has a chance of working. This was a loose end of the
implementation of the ACPI Cx idle states. Since our logical CPU Id
is the ACPI processor Id, we do not need to jump through hoops to
obtain it.

4e3a7a14d9 Fix a major faux pas of mine. I was causing 2 very bad things to
happen in interrupt context; 1) sleep locks, and 2) malloc/free
calls.

1) is fixed by using spin locks instead.

2) is fixed by preallocating a FIFO (implemented with a STAILQ)
   and using elements from this FIFO instead. This turns out
   to be rather fast.

a5ca5c1a75 A variety of content cleanups:
(1) Document the notion of using jail(8) to run "virtual servers" or
    just to constrain specific applications.  If only running specific
    applications, some configuration steps are unnecessary (such as
    editing rc.conf).

(2) Add some more subsection headers to break up the bigger chunks of
    text.

(3) Clarify the problems associated with applications binding all IP
    addresses in the host, and attempt to be more specific about
    potential application problems.  Document how to force sshd to
    bind the the right socket.

(4) Suggest that in a jailed application scenario, you might want to
    have the host syslogd listen on the socket in the jail, rather
    than running syslogd in the jail.

(5) Catch another reference to /stand/sysinstall.

c25a3f8a7a Improve the section on Cx states, documenting the removal of -1 as a

56a70eadf5 * Add a DEVMETHOD for acpi so that child detach methods get called. Add
an acpi_cpu method for shutdown that disables entry to acpi_cpu_idle
  and then IPIs/waits for threads to exit.  This fixes a panic late in
  reboot in the SMP case.

* In the !SMP case, don't use the processor id filled out by the MADT
  since there can only be one processor.  This was causing a panic in
  acpi_cpu_idle if the id was 1 since the data was being dereferenced from
  cpu_softc[1] even though the actual data was in cpu_softc[0] (which is
  correct).

* Rework the initialization functions so that cpu_idle_hook is written
  late in the boot process.

* Make the P_BLK, P_BLK_LEN, and cpu_cx_count all softc-local variables.
  This will help SMP boxes that have _CST or multiple P_BLKs.  No such
  boxes are known at this time.

* Always allocate the C1 state, even if the P_BLK is invalid.  This means
  we will always take over idling if enabled.  Remove the value -1 as
  valid for cx_lowest since this is redundant with machdep.cpu_idle_hlt.

* Reduce locking for the throttle initialization case to around the write
  to the smi_cmd port.  Add disabled code to write the CST_CNT.  It will
  be enabled once _CST re-evaluation is tested (post 5.2R).

- add 'device atpic' - this is unconditional on i386, but certain nvidia
  based systems need to disable acpi because the reference bios seems to be

bd8477d623 Force a staticly linked /bin and /sbin for ia64. The necessary changes
to gcc have not been made for ia64, which means that executables still
have /usr/libexec/ld-elf.so.1 as the dynamic linker. This simply does
not work if /usr is a seperate filesystem not mounted when the kernel
tries to execute init(8).

Note that this is a temporary fix until a new gcc has been imported
that does have the required changes.

f6a1906569 Lower the maximum ACK timeout for GRE packets from 10 to 1 second.
In practice it seems that in situations of high packet loss the ACK
timeout seems to hit this maximum (perhaps inappropriately, but the
estimation algorithm is not perfect, so apparently it happens). In
any case, 10 seconds is way too high a value so lower to 1 second.

a557af222b Introduce a MAC label reference in 'struct inpcb', which caches
the   MAC label referenced from 'struct socket' in the IPv4 and
IPv6-based protocols.  This permits MAC labels to be checked during
network delivery operations without dereferencing inp->inp_socket
to get to so->so_label, which will eventually avoid our having to
grab the socket lock during delivery at the network layer.

This change introduces 'struct inpcb' as a labeled object to the
MAC Framework, along with the normal circus of entry points:
initialization, creation from socket, destruction, as well as a
delivery access control check.

For most policies, the inpcb label will simply be a cache of the
socket label, so a new protocol switch method is introduced,
pr_sosetlabel() to notify protocols that the socket layer label
has been updated so that the cache can be updated while holding
appropriate locks.  Most protocols implement this using
pru_sosetlabel_null(), but IPv4/IPv6 protocols using inpcbs use
the the worker function in_pcbsosetlabel(), which calls into the
MAC Framework to perform a cache update.

Biba, LOMAC, and MLS implement these entry points, as do the stub
policy, and test policy.

0887c8c110 Overhaul the entropy device:
o Each source gets its own queue, which is a FIFO, not a ring buffer.
  The FIFOs are implemented with the sys/queue.h macros. The separation
  is so that a low entropy/high rate source can't swamp the harvester
  with low-grade entropy and destroy the reseeds.

o Each FIFO is limited to 256 (set as a macro, so adjustable) events
  queueable. Full FIFOs are ignored by the harvester. This is to
  prevent memory wastage, and helps to keep the kernel thread CPU
  usage within reasonable limits.

o There is no need to break up the event harvesting into ${burst}
  sized chunks, so retire that feature.

o Break the device away from its roots with the memory device, and
  allow it to get its major number automagically.
