076e3c1072 Update nfsd.8 for support of IPv6 addresses for hosts in the "-p" option.

35f38de3c9 Add support for IPv6 addresses to the pNFS "-p" option.
This patch adds code to handle IPv6 addresses returned by getaddrinfo()
for the host entries in the "-p" command line argument.
If the IPv6 address is a link local address, only use it if it is the
only address for the host. This is done since there is no way to know
if the NFSv4.1 pNFS client is in the same scope zone as the MDS.
inet_ntop() is used for the IPv6 address translation, since the client
will have no use for the scope zone suffix and inet_ntop() does not
put this in the address string.

0479387e0a Document the "#mds_path" suffix for the "-p" command line option.
r335871 added support for an optional suffix of "#mds_path" that can be
applied to each entry in the "-p" option argument. This specifies that
the DS should be used to store files for the file system on the MDS
at "mds_path".
This patch documents this optional suffix.

ed46427268 Add an optional feature to the pNFS server.
Without this patch, the pNFS server distributes the data storage files across
all of the specified DSs.
A tester noted that it would be nice if a system administrator could control
which DSs are used to store the file data for a given exported MDS file system.
This patch adds an optional suffix for each entry in the "-p" option argument
that specifies "store file data for this MDS file system" in this DS.
The patch should only affect sites using the pNFS server (specified via the
"-p" command line option for nfsd.
The interface between the nfsd and the kernel has changed with this patch,
so anyone using the "-p" option needs to rebuild their nfsd from sources
with this patch applied to them.

2f800e5593 Add a safety belt assignment to the nfsd for when "-p" isn't specified.
The kernel code assumes that nfsdargs.addr == NULL and nfsdargs.addrlen == 0
when there is no "-p" argument used for starting the nfsd.
This small patch ensures this is the case. In practice, I believe this always
happened, since "nfsdargs" was the last element on the stack for "main()",
but this little patch ensures it will be the case.
Spotted by inspection while adding a new optional field for "-p".

61a835e403 Add the "-p" and "-m" options to nfsd.c for the pNFS service.
The "-p" option specifies that the nfsd should run a pNFS service instead
of a regular NFS service. The "-m" option is only meaningful when used with
"-p" to specify that mirroring on the DSs should be done and on how many of
them.
This change requires the kernel changes committed as r334930.
The man page update will be committed as a separate commit soon.

8a16b7a18f General further adoption of SPDX licensing ID tags.
Mainly focus on files that use BSD 3-Clause license.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.

6242e8c886 Update the nfsv4 man page to reflect recent changes to support
the newer RFCs (5661 and 7530). The main man changes are for the
case of "numbers in strings" for user/groups that RFC7530 allows
and avoids use of nfsuserd(8).

Renumber cluase 4 to 3, per what everybody else did when BSD granted
them permission to remove clause 3. My insistance on keeping the same
numbering for legal reasons is too pedantic, so give up on that point.

df3e1050ff Patch the nfsd so that it doesn't register with rpcbind for an NFSv4 only
server.

This patch uses the sysctl vfs.nfsd.server_min_nfsvers to determine
if/what versions of NFS service should be registered with rpcbind.
For NFSv4 only, it does not register at all, since NFSv4 always uses 2049
and does not require rpcbind.
For NFSv3 minimum, it registers NFSv3 but not NFSv2.

535875c734 Simplify r243637 and make sure that nfsdargs.{min,max}threads are always set
to meaningful value:

 - When nfsdcnt is set, it dictates all values;
 - Otherwise, nfsdargs.minthreads is set to user specified value, or the
   automatically detected value if there is no one specified;
   nfsdargs.maxthreads is set to the user specified value, or the value
   of nfsdargs.minthreads if there is no one specified; when it is smaller
   than nfsdargs.minthreads, the latter's value is always used.
