machine credentials for accesses by uid 0 (the default behavior, as

Restore use of un-connected socket for UDP mount requests.

When connecting to an NFSv4 server we need to find out IP address
as it would be seen by the server, to register an address for
callbacks.
This is most easily done by connecting the socket to the
servers address and then getting the address of our endpoint.

However with a connected UDP socket, replies that come from a
different IP address - as can happen with non-Linux multi-homed
servers - will be rejected.

So if we connected our UDP socket, we need to be sure to
disconnect it before using it.

This patch adds an option to get_socket to say if we want it
connected or not and, in the case where we do, we disconnect
a UDP socket after the connection information has been used.

The previous patch seems to expose a use after free bug in dirscancb. At
least, I could reliably reproduce a segfault by doing a bunch of mounts
and then unmounting them all. The code uses the following list macro:

      TAILQ_FOREACH(ic, icq, ic_next) {

...to iterate over all of the ic entries and clean up any that no longer
have a corresponding directory in rpc_pipefs. This macro unrolls into:

      for(ic=icq->tqh_first; ic != NULL; ic=ic->ic_next.tqe_next) {

...but within this loop, we can free ic, and then the for loop can trip
over that when it tries to do the iteration. The attached patch works
around this by not using the TAILQ_FOREACH macro and saving off the
tqe_next pointer prior to the free.

Again, this was tested on a patched 1.0.6, but the 1.0.10 code is very

Various minor manpage fixes.

         This mostly takes care of the difference between
         - and \-; in man pages, the former is hyphen
         (which indicates, among others, that a line might
         be split at that point), while the latter is a
         dash. For options, the latter is correct.

         There's also one minor grammatical fix.

problems on some distgributions.

Allow default options in /etc/exports

  Implement default options in /etc/exports, to fix a long-standing wishlist
  bug in Debian. (The user claims the syntax matches that of OpenBSD.) This
  makes it possible to write "/srv/www -sync,no_subtree_check host1 host2 host3"
  instead of having to write (sync,no_subtree_check) over and over and over
  again, driving the administrator slowly mad. Such option lines can be
  placed anywhere on the line, and affects anything after them (I do not
  know if OpenBSD allows this). The patch is slightly convoluted in order to
  avoid triggering spurious warnings; for instance, we want
  "/srv/www -sync host1" to trigger a warning, but not "/srv/www
  -sync,no_subtree_check host1" or "/srv/www -sync host1(no_subtree_check)".

  There was also a suggestion for a truly global (ie. per-file) option list,
  but this seemed like the safest bet, given that it matches that of other
  implementations.

  Also, the man page is updated with information on the new possibilities,
  and an example.

Make mountd complain on unsupported uid mapping schemes

  The NFS kernel server does not support uid mappings, activated with flags
  such as "map_daemon" in exports. There is already code that parses these
  flags, and gives an error at mount time if an unsupported flag (ie. any
  but the default) is given. However, at some point the kernel changed the
  export interface, and the new code forgot to include the relevant check.
  Thus, simply copy the check from the old to the new code, which makes
  sure mountd behaves the same in this aspect regardless of kernel version,
  and makes sure the admin does not inadvertently use map_daemon and expect
  it to work.
