To support FedFS and NFS junctions without introducing additional
build-time or run-time dependencies on nfs-utils, the community has
chosen to use a dynamically loadable library to handle junction
resolution.
There is one plug-in library for mountd that will handle any NFS-
related junction type. Currently there are two types:
o nfs-basic locally stored file set location data, and
o nfs-fedfs file set location data stored on an LDAP server
mountd's support for this library is enabled at build time by the
presence of the junction API definition header:
/usr/include/nfs-plugin.h
If this header is not found on the build system, mountd will build
without junction support, and will operate as before.
Note that mountd does not cache junction resolution results. NFSD
already caches these results in its exports cache. Thus each time
NFSD calls up to mountd, it is, in essence, requesting a fresh
junction resolution operation, not a cached response.

Neither m4 nor the vim colorizer like unbalanced single quotes.
Similar change as commit 34ee5730.
Also, the default value of the command line option is conventionally
listed in the right-hand side argument of AC_HELP_STRING.

To allow greater flexibility to where statd's state is kept,
statd's state path can now be decoupled from the normal
NFS state directory.
In configure.ac, the NSM_DEFAULT_STATEDIR definition will now define
the path to where the state information is kept. The default
value, /var/lib/nfs, can be redefined with the --with-statdpath
flag.

This patch allows to link mount.nfs with libmount from util-linux >=
v2.19. The new libmount based code is enabled by CONFIG_LIBMOUNT and
is stored in mount_libmount.c. The old code is not affected by this
change.
The libmount does not have officially stable API yet, so the
--enable-libmount-mount is marked as experimental in the configure
help output.
The ./configure option is the same as we use in util-linux to enable
support for libmount in mount(8).
The addr= (and some other options necessary for remount/umount) are
stored to /etc/mtab or to /dev/.mount/utab. The utab file is *private*
libmount file. It's possible that some mount options (for example
user=) will be moved to kernel, so the utab will not be necessary.
About libmount:
* supports systems without and with regular /etc/mtab
* does not store VFS and FS mount options in userspace
* manages user= option and evaluate permissions
* parses VFS mount options and generate MS_* flags
* parses /etc/{fstab,mtab}, /proc/mounts or /proc/self/mountinfo
* long-term goal is to use the same code in all mount.<type> helpers
Note, use
LIBMOUNT_DEBUG=0xffff mount.nfs foo:/path /path
to debug the library.
On systems with util-linux v2.19 the findmnt(8) command uses libmount
to list all/selected mount points:
$ findmnt /path
$ findmnt --mtab /path
the --mtab appends userspace mount options (e.g. user=) to the output.

We need $enable_tirpc to be a tristate. 'yes' means that someone
explicitly requested building with tirpc. 'no' means that it was
explicitly disabled. Anything else means that no one specified a value.
Fix it by setting the value to a blank string so that the default is
properly undefined.

After glibc 2.3.3, getifaddrs(3) can return AF_INET6 addresses for
local network interfaces. Using the library call is easier than
trying to update the open code in from_local(), and means we have
less to maintain in nfs-utils going forward.
And, since from_local() can now support IPv6, change its synopsis to
take a "struct sockaddr *" .
Note that the original code discovers local addresses once. These
days, with wifi, DHCP, and NetworkManager, the local network
configuration can change dynamically over time. So, call getifaddrs()
more often to ensure from_local() has up-to-date network configuration
information.
This implementation refreshes the list if from_local() has not been
called in the last second. This is actually not terribly honerous.
check_default() invokes from_local() only when the remote host is not
in its access cache, or the access/deny files have changed.
So new hosts will cause a refresh, but previously seen hosts
(including localhost) should not.
On the other hand, it still may not be often enough. After the first
call, if only previously seen hosts attempt to access our daemons,
from_local() would never be called, and the local list would never be
updated. This might be possible during steady-state operation with
a small number of servers and clients.
It would also be nice if we could free the local interface address
list at shutdown time, but that would be a lot of trouble for little
gain.

I'm about to switch the order of listener creation and dropping root
privileges. rpc.statd will drop privileges first, then create its
listeners. The reason for the new ordering is explained in a
subsequent patch.
However, for non-TI-RPC builds, rpc_init() needs to use a privileged
port to do pmap registrations. For both TI-RPC and non-TI-RPC builds,
CAP_NET_BIND is required in case the admin requests a privileged
listener port on the statd command line.
So that these requirements are met, nsm_drop_privileges() will now
retain CAP_NET_BIND while dropping root.

rpc.statd is often prone to subtle, difficult to detect breakage. When
it has problems, they're often invisible and only manifest themselves
as failed lock recovery.
This program is intended to function as part of a test harness for
statd. It's a multicall binary that serves as a synthetic NSM client
program, and a daemon that can simulate lockd for purposes of testing
the NSM to NLM downcall.
A new top level "tests/" directory is also added to nfs-utils to start
as a repository for automated tests of nfs-utils components.

Clean up: Move the .x file and the generated C source for NSM to
libnsm.a, echoing the architecture of mountd and exportfs. This makes
the NSM protocol definitions, data types, and XDR routines available
to be shared across nfs-utils.
This simplifies the addition of other NSM-related code (for example
for testing or providing clustering support), and also provides
public data type definitions that can be used to make sense of the
contents of statd's on-disk database.
Because sim_sm_inter.x still resides in utils/statd, I've left some
rpcgen build magic in utils/statd/Makefile.am.
This is an internal organization change only. This patch should not
affect code behavior in any way.

Systems that are so old that they don't have getnameinfo() in glibc are
probably also running kernels that are so old that they don't support
gssapi upcalls anyway.
Make --enable-gss dependent on the presence of the getnameinfo()
function. This allows us to reduce some conditional compilation.
