cc084f7587 Axe TCP_RESTRICT_RST. It was never a particularly good idea except for a few
very specific scenarios, and now that we have had net.inet.tcp.blackhole for
quite some time there is really no reason to use it any more.

8360efbd6c Bring in a hybrid of SunSoft's transport-independent RPC (TI-RPC) and
associated changes that had to happen to make this possible as well as
bugs fixed along the way.

  Bring in required TLI library routines to support this.

  Since we don't support TLI we've essentially copied what NetBSD
  has done, adding a thin layer to emulate direct the TLI calls
  into BSD socket calls.

  This is mostly from Sun's tirpc release that was made in 1994,
  however some fixes were backported from the 1999 release (supposedly
  only made available after this porting effort was underway).

  The submitter has agreed to continue on and bring us up to the
  1999 release.

  Several key features are introduced with this update:
    Client calls are thread safe. (1999 code has server side thread
    safe)
    Updated, a more modern interface.

  Many userland updates were done to bring the code up to par with
  the recent RPC API.

  There is an update to the pthreads library, a function
  pthread_main_np() was added to emulate a function of Sun's threads
  library.

  While we're at it, bring in NetBSD's lockd, it's been far too
  long of a wait.

  New rpcbind(8) replaces portmap(8) (supporting communication over
  an authenticated Unix-domain socket, and by default only allowing
  set and unset requests over that channel). It's much more secure
  than the old portmapper.

  Umount(8), mountd(8), mount_nfs(8), nfsd(8) have also been upgraded
  to support TI-RPC and to support IPV6.

  Umount(8) is also fixed to unmount pathnames longer than 80 chars,
  which are currently truncated by the Kernel statfs structure.

248aee623c Add nsswitch support. By creating an /etc/nsswitch.conf file, you can
configure FreeBSD so that various databases such as passwd and group can be
looked up using flat files, NIS, or Hesiod.

= Hesiod has been added to libc (see hesiod(3)).

= A library routine for parsing nsswitch.conf and invoking callback
  functions as specified has been added to libc (see nsdispatch(3)).

= The following C library functions have been modified to use nsdispatch:
    . getgrent, getgrnam, getgrgid
    . getpwent, getpwnam, getpwuid
    . getusershell
    . getaddrinfo
    . gethostbyname, gethostbyname2, gethostbyaddr
    . getnetbyname, getnetbyaddr
    . getipnodebyname, getipnodebyaddr, getnodebyname, getnodebyaddr

= host.conf has been removed from src/etc.  rc.network has been modified
  to warn that host.conf is no longer used at boot time.  In addition, if
  there is a host.conf but no nsswitch.conf, the latter is created at boot
  time from the former.

8d1b3828fa Add a sysctl to specify the amount of UDP receive space NFS should
reserve, in maximal NFS packets.  Originally only 2 packets worth of
    space was reserved.  The default is now 4, which appears to greatly
    improve performance for slow to mid-speed machines on gigabit networks.

    Add documentation and correct some prior documentation.

The isdnd is able to listen on a socket for isdnmonitor to connect to
it to remotely control it (similar to ppp and pppctl). When this is
enabled in the isdnd config file, it will fail currently because isdnd
is started before the network interfaces are configured.
It is necessary to move the isdnd start after the ifconfig of the network
interfaces, then this problem will not occur.

ab80d6fabc This is another in Martin Blapp's N-series of mount-related cleanups :)
Changes are:
 - rpc.umntall is called at the right places now in /etc/rc*
 - rpc.umntall timeout has been lowered from two days (too high) to one
 - verbose messages in rpc.umntall have been clarified
 - kill double entries in /var/db/mounttab when rpc.umntall is invoked
 - ${early_nfs_mounts} has been removed from /etc/rc
 - patched mount(8) -p to print different pass/dump values for ufs filesystems.

9c65a84aea Do away with ${network_interfaces} in rc.conf. Just use ifconfig -l to
get a list of interfaces, and then automatically configure them if
${ifconfig_${ifn}} or /etc/start_if.${ifn} exists.

This makes it a lot easier to deal with machines that constantly change
their network configuration as you can leave ifconfig settings for all
the possible cards - just the ones that are present will be configured.

7389b9fd55 Don't discard error output from sysctl(8).
Do discard standard output from the sysctl for approxy_all, and echo
what this sysctl is doing in the usual way.  This fix is probably
backwards.  We should probably just use the standard sysctl output
in all cases (it needs to have a newline filtered out).

Echo what the sysctls for nfs_reserved_port_only and nfs_access_cache
are doing.

2c7b227278 Add handle to control global TCP keepalives and turn them on as
default.

Despite their name it doesn't keep TCP sessions alive, it kills
them if the other end has gone AWOL.  This happens a lot with
clients which use NAT, dynamic IP assignment or which has a 2^32
* 10^-3 seconds upper bound on their uptime.

There is no detectable increase in network trafic because of this:
two minimal TCP packets every two hours for a live TCP connection.

Many servers already enable keepalives themselves.

The host requirements RFC is 10 years old, and doesn't know about
the loosing clients of todays InterNet.
