umount.nfs: Distinguish between nfs4 and nfs mounts
Neil Brown reports that umount.nfs is still confused by "-t nfs -o
vers=4" mounts.
/etc/mtab can be confused. /proc/mounts is authoritative on the
fstype of a mount. Have umount.nfs consult it to determine which
mechanism to use for unmounting. The code to read /proc/mounts was
lifted from the nfsstat command.
The code introduced by this patch may look like belt-n-suspenders, but
we have two use cases to consider:
1. Old kernels don't support the "vers=4" mount option, so
umount.nfs must look for the "nfs4" fstype
2. Upcoming kernels may eliminate support the "nfs4" fstype, so
umount.nfs must look for the "vers=4" mount option
Thus this logic checks for "nfs4" first then looks for the NFS version
setting.
Note that we could handle unmounting entirely in the kernel, but that
won't help older kernels that have this issue.

libnfs.a: Allow multiple RPC listeners to share listener port number
Normally, when "-p" is not specified on the mountd command line, the
TI-RPC library chooses random port numbers for each listener. If a
port number _is_ specified on the command line, all the listeners
will get the same port number, so SO_REUSEADDR needs to be set on
each socket.
Thus we can't let TI-RPC create the listener sockets for us in this
case; we must create them ourselves and then set SO_REUSEADDR (and
other socket options) by hand.
Different versions of the same RPC program have to share the same
listener and SVCXPRT, so we have to cache xprts we create, and re-use
them when additional requests for registration come from the
application.
Though it doesn't look like it, this fix was "copied" from the legacy
rpc_init() function. It's more complicated for TI-RPC, of course,
since a TI-RPC application can set up listeners with a nearly
arbitrary number of address families and socket types, not just the
two listeners that legacy RPC applications can set up (one for AF_INET
UDP and one for AF_INET TCP).

rpc.nfsd: mount up nfsdfs is it doesn't appear to be mounted yet
There's a bit of a chicken and egg problem when nfsd is run the first
time. On Fedora/RHEL at least, /proc/fs/nfsd is mounted up whenever nfsd
is plugged in via a modprobe.conf "install" directive.
If someone runs rpc.nfsd without plugging in nfsd.ko first,
/proc/fs/nfsd won't be mounted and rpc.nfsd will end up using the legacy
nfsctl interface. After that, nfsd will be plugged in and subsequent
rpc.nfsd invocations will use that instead.
This is a problem as some nfsd command-line options are ignored when the
legacy interface is used. It'll also be a problem for people who want
IPv6 enabled servers. The upshot is that we really don't want to use the
legacy interface unless there is no other option.
To avoid this situation, have rpc.nfsd check to see if the "threads"
file is already present. If it's not, then make an attempt to mount
/proc/fs/nfsd. This is a "best-effort" sort of thing, however so we
just ignore the return code from the mount attempt and fall back to

libnfs.a: Fix API for getfh() & friends
This is more of a clean-up than a behavioral change.
POSIX requires that a "struct sockaddr" is the same size as a "struct
sockaddr_in". Therefore, a variable or field of type "struct sockaddr"
cannot contain an AF_INET6 address. However, "struct sockaddr *" is
often used to reference a generic (ie non-address family specific)
socket address, generating some confusion about this.
The nfsctl_arg struct uses a struct sockaddr (not a pointer) to pass
the client's IP address to the kernel. This means the legacy nfsctl()
kernel API can never support IPv6. Fortunately for us, this legacy
interface was replaced by a text-based cache interface a few years
back. We don't need to support non-AF_INET addresses here.
The getfh() functions in nfs-utils provide a handy C API for the
kernel's nfsctl interface. The getfh() functions still take a struct
sockaddr *, though, and that can imply that a non-IPv4 address can be
passed via this API. To make it abundantly clear that only IPv4
addresses can be used with this interface, change the synopses of
getfh() and friends to take a struct sockaddr_in * instead of a struct
sockaddr * .
This makes these functions conform with other places in mountd and
exportfs that already grok the difference between a struct sockaddr
and a struct sockaddr_in.
While we're here...
Introduce some nice documenting comments for the get_fh() functions,
and...
Since mountd will support IPv6 in the near future, assert that the
family of client addresses passed to this API is indeed AF_INET, in
order to prevent non-AF_INET addresses from ever being passed to the
legacy nfsctl() interface.

mount.nfs: Refactor mount version and protocol autonegotiation
Clean up.
I'm beginning to agree with Bruce and Steve's assessment that the
fallthrough switch case in nfs_try_mount() is more difficult to read
and understand than it needs to be. The logic that manages
negotiating NFS version and protocol settings is getting more complex
over time anyway.
So let's split the autonegotiation piece out of nfs_try_mount().
We can reduce indenting, and use cleaner switch-based logic. Also,
adding more comments can only help.
Neil also suggested replacing the pre-call "errno = 0" trick. The
lower-level functions may try to mount several times (given a list of
addresses to try). errno could be set by any of those. The mount
request will succeed at some point, and "success" is returned, but
errno is still set to some non-zero value.
The kernel version check in nfs_try_mount() is more or less loop
invariant: it's impossible for the result of that test to change
between retries. So we should be able to safely move it to the logic
that sets the initial value of mi->version.
