13190d8754 Allow users to use the 'nolockd' or -L options with mount_nfs in order
to avoid the need for rpc.lockd to perform client locks.  Using
this option a user can revert back to using local locks for NFS mounts
like we did before we had rpc.lockd.

2bc53e1178 Change the foreground mount behaviour so that we keep retrying
forever by default. This matches what mount_nfs did before revision
1.40, and it is the generally expected behaviour for NFS mounts.

Document the current defaults near the start of the man page and
mention the options that can be used to change them.

e16873dad6 Since revision 1.40/1.41, the default behaviour for mount_nfs is
to give up after one attempt unless a background mount is requested.
Background mounts would retry 10000 times (at least 7 days) before
giving up.

For some situations such as diskless terminals, an NFS filesystem
may be critical to the boot process, so neither the "try once" nor
background mounts are appropiate. To cater for this situation,
unbreak the -R (retry count) parameter so that it also works in
the non-background case. Interpret a zero retry count as "retry
forever".

The defaults are now "try once" for non-background mounts and "retry
forever" for background mounts; both can be overridden via -R.
Add a description of this behaviour to the manpage.

eca1c24e5a Use the new CLSET_CONNECT clnt_control() request on UDP clients to
ensure that we never proceed with the mount() syscall if the server
is replying from the wrong source address. Previously the userland
RPC call to the remote nfsd would succeed, but the kernel uses
connect() so it would not see the replies, resulting in a hung
mount.

a3d8f94bd4 - Split out the {family,socktype}->netid conversion into a separate
function; we now handle unknown protocols more gracefully.

- Cache the return from getnetconfigent() so that we don't have to
  remember to call freenetconfigent() each time. This fixes a memory
  leak that would cause retrying background mount_nfs processes to
  slowly increase their memory usage.

317d5933d4 Split out all the RPC code into a separate function and address a
number of issues:

- Fix background mounts; these were broken in revision 1.40.
- Don't give up before trying all addresses returned by getaddrinfo().
- Use protocol-independent routines where possible.
- Improve error reporting for RPC errors.
- In non-background mode, give up after trying all protocols once.
- Use daemon(3) instead of rolling our own version.
- Never go ahead with the mount() syscall until we have received
  a reply from the remote nfsd; this is especially important with
  non-interruptible mounts, as otherwise a mistyped command might
  require a reboot to correct.

of pingnfsserver(). The pingnfsport() function is now called everytime.
  If we don't get RPC_SUCCESS or RPC_PROGVERSMISMATCH back, there's
  something wrong with the NFS server and we just exit.

- Fixed the looping when we did not run background mode.

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.

a69497d73f Finish up umntall support. init now passed an argument to the
rundown script 'reboot' or 'single'.  ISO support (which never
    worked) has been removed from mount_nfs.  mount_nfs and umount
    now use mounttab, which allows umntall to work properly.  The
    rc scripts now call umntall as appropriate.

73dd316734 mount* fixes from Martin Blapp <mb@imp.ch>:
Made mount more userfriendly (bad slashes are now filtered out)
        and we remove in mount_nfs trailing slashes if there are any.

        Fixed mount_xxx binarys to resolve with realpath(3)
        the mountpoint.

        Translate the deprecated nfs-syntax with '@' to ':' .
        The ':' syntax has now precedence, but '@' still works.
        Notify the user that the '@' syntax should not be used.

d5e1fb3173 Make mount_nfs use reserved ports by default.. Mounts already use
a reserved port, so why not the nfs rpc's themselves?
With user allowed mounts, this perhaps needs a closer look, but
on the other hand, a user could already specify the flag.
If normal users should not be able to use resserved ports, the kernel
should check for the flag at mount time.

a62dc40654 Changes to support version 3 of the NFS protocol.
The version 2 support has been tested (client+server) against FreeBSD-2.0,
IRIX 5.3 and FreeBSD-current (using a loopback mount).  The version 2 support
is stable AFAIK.
The version 3 support has been tested with a loopback mount and minimally
against an IRIX 5.3 server.  It needs more testing and may have problems.
I have patched amd to support the new variable length filehandles although
it will still only use version 2 of the protocol.

Before booting a kernel with these changes, nfs clients will need to at least
build and install /usr/sbin/mount_nfs.  Servers will need to build and
install /usr/sbin/mountd.

NFS diskless support is untested.

3fa88dec7f Add support for filesystem-specific `-o' options, and re-implement the
most common cd9660 and nfs options like God intended them.  (It is now
possible to say

	mount -o ro,soft,bg,intr there:/foo/bar /foo/bar

again.)  This whole getmntopt() business is an incredible botch;
it never should have been anything more than a wrapper around
getsubopt(3).  Because if the way the current hackaround is implemented,
options which take arguments (like the old `rsize' and `wsize') are still
unavailable, and must be accessed the new, broken way.

(It's unimaginable how Berkeley managed to screw up one of the few things
about NFS that Sun actually got right to begin with!)
