35e3987f15 In printfile(), exit the process instead of only printing the warning.
This fixes verbose mode when either -i specified non-existent kldfile
id, or the file was unloaded between two kldnext(2) calls.

While there, fix printfile() definition to be style(9)-compliant.

initialize ni_txrate on none_node_init() calls.

e61ffaea2a Fix bug in jn(3) and jnf(3) that led to -inf results
Explanation by Steve:
jn[f](n,x) for certain ranges of x uses downward recursion to compute
the value of the function.  The recursion sequence that is generated is
proportional to the actual desired value, so a normalization step is
taken.  This normalization is j0[f](x) divided by the zeroth sequence
member.  As Bruce notes, near the zeros of j0[f](x) the computed value
can have giga-ULP inaccuracy. I found for the 1st zero of j0f(x) only
the leading decimal digit is correct.  The solution to the issue is
fairly straight forward.  The zeros of j0(x) and j1(x) never coincide,
so as j0(x) approaches a zero, the normalization constant switches to
j1[f](x) divided by the 2nd sequence member.  The expectation is that
j1[f](x) is a more accurately computed value.

169733f46d Break out the rules which generate crunchgen'ed binaries into a separate
.mk file so they can be reused.

Introduce a new option, CRUNCH_BUILDTOOLS, which lists the binaries that
require tools built in the local architecture. sh and csh both require this.
It was previously hardcoded in rescue/rescue/Makefile .

Introduce a new option, CRUNCH_SHLIBS, which lists the shared libraries
to link against. These override the static libraries listed in CRUNCH_LIBS.
Some build environments may wish to use a handful of shared libraries
(eg libc.so) so other small, dynamic binaries can be run in the environment.

Remove the now-shared code from rescue/rescue/Makefile and introduce the
CRUNCH_BUILDTOOLS option for the above shells.

e162ea60d4 Add a queue to hold packets while we await an ARP reply.
When a fast machine first brings up some non TCP networking program
it is quite possible that we will drop packets due to the fact that
only one packet can be held per ARP entry.  This leads to packets
being missed when a program starts or restarts if the ARP data is
not currently in the ARP cache.

This code adds a new sysctl, net.link.ether.inet.maxhold, which defines
a system wide maximum number of packets to be held in each ARP entry.
Up to maxhold packets are queued until an ARP reply is received or
the ARP times out.  The default setting is the old value of 1
which has been part of the BSD networking code since time
immemorial.

Expose the time we hold an incomplete ARP entry by adding
the sysctl net.link.ether.inet.wait, which defaults to 20
seconds, the value used when the new ARP code was added..

5c9d0a9ad3 This commit implements the SO_USER_COOKIE socket option, which lets
you tag a socket with an uint32_t value. The cookie can then be
used by the kernel for various purposes, e.g. setting the skipto
rule or pipe number in ipfw (this is the reason SO_USER_COOKIE has
been implemented; however there is nothing ipfw-specific in its
implementation).

The ipfw-related code that uses the optopn will be committed separately.

This change adds a field to 'struct socket', but the struct is not
part of any driver or userland-visible ABI so the change should be
harmless.

dbc4240942 This commit marks the first formal contribution of the "Five New TCP Congestion
Control Algorithms for FreeBSD" FreeBSD Foundation funded project. More details
about the project are available at: http://caia.swin.edu.au/freebsd/5cc/

- Add a KPI and supporting infrastructure to allow modular congestion control
  algorithms to be used in the net stack. Algorithms can maintain per-connection
  state if required, and connections maintain their own algorithm pointer, which
  allows different connections to concurrently use different algorithms. The
  TCP_CONGESTION socket option can be used with getsockopt()/setsockopt() to
  programmatically query or change the congestion control algorithm respectively
  from within an application at runtime.

- Integrate the framework with the TCP stack in as least intrusive a manner as
  possible. Care was also taken to develop the framework in a way that should
  allow integration with other congestion aware transport protocols (e.g. SCTP)
  in the future. The hope is that we will one day be able to share a single set
  of congestion control algorithm modules between all congestion aware transport
  protocols.

- Introduce a new congestion recovery (TF_CONGRECOVERY) state into the TCP stack
  and use it to decouple the meaning of recovery from a congestion event and
  recovery from packet loss (TF_FASTRECOVERY) a la RFC2581. ECN and delay based
  congestion control protocols don't generally need to recover from packet loss
  and need a different way to note a congestion recovery episode within the
  stack.

- Remove the net.inet.tcp.newreno sysctl, which simplifies some portions of code
  and ensures the stack always uses the appropriate mechanisms for recovering
  from packet loss during a congestion recovery episode.

- Extract the NewReno congestion control algorithm from the TCP stack and
  massage it into module form. NewReno is always built into the kernel and will
  remain the default algorithm for the forseeable future. Implementations of
  additional different algorithms will become available in the near future.

- Bump __FreeBSD_version to 900025 and note in UPDATING that rebuilding code
  that relies on the size of "struct tcpcb" is required.

fe3b4685c7 Remove use of a separate ofw_pmap on 32-bit CPUs. Many Open Firmware
mappings need to end up in the kernel anyway since the kernel begins
executing in OF context. Separating them adds needless complexity,
especially since the powerpc64 and mmu_oea64 code gave up on it a long
time ago.

As a side effect, the PPC ofw_machdep code is no longer AIM-specific,
so move it to powerpc/ofw.
