    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
    using nfsctl() if it fails.

    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.
    
    This patch is not supposed to cause a behavioral change.

    mount.nfs: Prepare way for "vers=4,rdma" mounts
    
    At some point, when the kernel starts to support "vers=4,rdma" mounts,
    we will want the mount.nfs command to pass "vers=4,rdma" mounts

    Assuming that the kernel will reject these today with EPROTONOSUPPORT,
    that would cause the version fallback logic to go to "vers=3,rdma"
    automatically.  So the extra check we have now is not needed anyway.

    mount.nfs: Support an "rdma" mount option
    
    The kernel NFS client's mount option parser recognizes a stand-alone
    "rdma" mount option, similar to the legacy "udp" and "tcp" options.
    
    The mount.nfs command text-based mount option parser used to pass
    "rdma" straight to the kernel, but since we've started handling MNT in
    the kernel instead of in user space, "rdma" on the command line has
    not worked.
    
    Until now, no-one has noticed, especially since an "rdma" mount option

    getport: Recognize "rdma" and "rdma6" netid
    
    The mount.nfs command must recognize the values of "rdma" and "rdma6"
    with the "proto=" mount option.  Typically the mount.nfs command
    relies on libtirpc or getprotobyname(3) to recognize netids and
    translate them to protocol numbers.
    
    RFCs 5665 and 5666 define the "rdma" and "rdma6" netids.  IANA defines
    a specific port number for NFS over RDMA (20049), but has not provided
    a protocol name and number for RDMA transports, and is not expected
    to.  The best we can do is translate these by hand, as needed, to get
    RDMA mount requests to the kernel without erroring out.
    
    Only the forward translation is needed until such time that "rdma" and
    "rdma6" start to appear in rpcbind registries.  For now, the version
    and transport negotiation logic is skipped, avoiding rpcbind queries
    for RDMA mounts.
    
    Note: As of kernel 2.6.36, the kernel's NFS over RDMA transport
    capability does not support IPv6.

    libexport.a: Refactor init_netmask()
    
    Instead of a single function that can handle both AF_INET and AF_INET6
    addresses, two separate functions might be cleaner.
    
    The original plan was to keep code redundancy at a minimum, but the
    resulting code was cumbersome at best.  I think I've traded a little
    extra code for something that will be much easier to read, understand,
    and maintain.
    
    I've also eliminated the "#if / #endif" instances inside the functions.

    libexport.a: IPv6 support for client_init_subnet()
    
    To parse and store an IPv6 host or subnet address, init_netmask()
    needs to handle 128 bit subnet masks.
    
    Unfortunately what once was a pretty simple little function has grown
    much larger.  This logic must now not only parse IPv6 addresses
    correctly, but must also distinguish between IPv4 and IPv6.
    
    To avoid code duplication, I'm "bending" the cardinal rule of not
    using "#ifdef" inside functions.

    libexport.a: Prepare init_subnetwork() for IPv6 support
    
    Retire the slash32 logic in inet_netmask() in favor of a more generic
    netmask parser that can support IPv6 addresses.
    
    If an invalid IP address string is given to inet_addr(3), it returns
    INADDR_NONE, which is actually a "valid" address (255.255.255.255).
    We're none the wiser to the substitution until something breaks later.
    
    This patch provides better sanity checking of the parsed address, now
    that such an error can be reported to client_init()'s callers.
    We can also check the prefixlen value a little more carefully as well.

    exportfs: Use xlog() for error reporting
    
    exportfs already invokes xlog_open() because libexport.a uses xlog()
    exclusively for error reporting and debugging messages.  If we can
    use xlog() throughout exportfs itself, that enables xlog debugging
    messages everywhere in the code path.
    
    In addition, use xlog() instead of fprintf(stderr) for reporting
    errors in exportfs.c, to be consistent with libexport.a and other

    statd: statd fails to monitor if no reverse mapping of mon_name exists
    
    Commit 8ce130c4 switched in the new statd_canonical_name() function
    that constructs a "unique" name statd can use to uniquely identify a
    monitor record.
    
    The legacy statd would monitor a client that sent an IP address with
    no reverse map as its caller_name.  To remain bug-for-bug compatible,
    allow this case in the new statd.
    
    This shouldn't be a problem: statd_canonical_name() needs to create
    a unique name for the monitored host so it can keep track of monitor
    requests from the same remote.  The IP address itself should work as
    well as the host's canonical name, in case there is no reverse
    mapping.
    
    We still enforce the requirement that a mon_name that is a DNS name
    must have a forward map to an IP address.

    libexport: Fix IP address check in check_netgroup()
    
    Neil Brown reports that recent changes to replace
    gethostby{addr,name}(3) with get{addr,info}name(3) may have
    inadvertently broken netgroup support.
    
    There used to be a gethostbyaddr(3) call in the third paragraph in
    check_netgroup().  The reason for that gethostbyaddr(3) call was that
    the first innetgr(3) call has already confirmed that hname is not a
    member of the netgroup.  We also need to confirm that, if hname
    happens to be an IP address, the hostname bound to that IP address is
    not a member of the netgroup, either.
    
    Fix this by restoring appropriate address to hostname mapping of hname
    before retrying the innetgr(3) call.
    
    See http://marc.info/?l=linux-nfs&m=128084830214653&w=2 .

    libexport.a: Replace matchhostname()
    
    So that exportfs can eventually support IPv6 addresses, copy statd's
    getaddrinfo(3)-based matchhostname to exportfs, with adjustments for
    dealing with export wildcards and netgroups.  Until exportfs has full
    IPv6 support, however, we want to ensure that IPv6 addresses continue
    to remain blocked in the address comparison code used by exportfs.  At
    a later point we'll replace much of this with the generic functions
    in sockaddr.h.
    
    Since it contains special logic for handling wildcard and netgroups,
    this function is specialized for exportfs, and does not belong in
    one of the shared libraries.

    mountd: Replace "struct hostent" with "struct addrinfo"
    
    struct hostent can store either IPv4 or IPv6 addresses, but it can't
    store both address families concurrently for the same host.  Neither
    can hostent deal with parts of socket addresses that are outside of
    the sin{,6}_addr field.
    
    Replace the use of "struct hostent" everywhere in libexport.a, mountd,
    and exportfs with "struct addrinfo".  This is a large change, but
    there are so many strong dependencies on struct hostent that this
    can't easily be broken into smaller pieces.
    
    One benefit of this change is that hostent_dup() is no longer
    required, since the results of getaddrinfo(3) are already dynamically
    allocated.

    Improve support for exporting btrfs subvolumes
    
    If you export two subvolumes of a btrfs filesystem, they will both be
    given the same uuid so lookups will be confused.
    blkid cannot differentiate the two, so we must use the fsid from
    statfs64 to identify the filesystem.
    
    We cannot tell if blkid or statfs is best without knowing internal
    details of the filesystem in question, so we need to encode specific
    knowledge of btrfs in mountd.  This is unfortunate.
    
    To ensure smooth handling of this and possible future changes in uuid
    generation, we add infrastructure for multiple different uuids to be
    recognised on old filehandles, but only the preferred on is used on
    new filehandles.

    Mountd listens on 2 different versions for NFSv2 (MOUNTv1 and MOUNTv2)
    and one for NFSv3 (MOUNTv3)
    
    When --no-nfs-version requests an NFS version to be disabled, the
    code actually disabled the MOUNT version. This works is several cases,
    but requires --no-nfs-version 1 to completely disable NFSv2, which
    is wrong.
    
    So if we do disable 1, 2, and 3. mountd complain and won't run, it
    is not possible to run just v4 - i.e. not listening for MOUNT requests
    at all (as v4 doesn't need them).
    
    So change the handling of "--no-nfs-version 2" it disable MOUNTv1 as
    well as
    MOUNTv2, and allow mountd to continue running as long as one of
    NFSv2 NFSv3 NFSv4 is enabled.

    mountd/exportfs: Make m_addrlist field a nfs_sockaddr
    
    To store non-AF_INET addresses in the nfs_client structure, we need to
    use more than in_addr for the m_addrlist field.  Make m_addrlist
    larger, then add a few helper functions to handle type casting and
    array indexing cleanly.
    
    We could treat the nfs_client address list as if all the addresses
    in the list were the same family.  This might work for MCL_SUBNETWORK
    type nfs_clients.  However, during the transition to IPv6, most hosts
    will have at least one IPv4 and one IPv6 address.  For MCL_FQDN, I
    think we need to have the ability to store addresses from both
    families in one nfs_client.
    
    Additionally, IPv6 scope IDs are not part of struct sin6_addr.  To
    support link-local IPv6 addresses and the like, a scope ID must be
    stored.
    
    Thus, each slot in the address list needs to be capable of storing an
    entire socket address, and not simply the network address part.

    libexport.a: Allow malloc(3) failures in client_lookup() and friends
    
    Clean up: Use malloc(3) instead of xmalloc() in client_lookup() and
    client_dup(), ensuring that a failed memory allocation here doesn't
    cause our process to exit suddenly.
    
    Allocation of nfs_client records and the m_hostname string are now
    consistently handled with malloc(3), calloc(3), strdup(3), and
    free(3).

    libexport.a: export_find() should handle address parsing errors
    
    An address mask parsing error can cause client_init(), and therefore
    client_dup(), to make our process exit suddenly.  Soon we want to add
    more complex address parsing in client_init(), so we need this
    interface to be a little more robust.
    
    Since export_find() can return NULL in some cases, it can handle NULL
    returns from its subroutines if an address parsing error occurs, or if
    memory is exhausted.  Allow for client_dup() to return NULL instead of
    exiting sideways.

    mount: Mount should retry unreachable hosts
    
    Currently if a server is up but not responding (ie, it answers ARP
    requests, but not NFS or RPC requests), mount retries or backgrounds
    itself waiting for the server.
    
    If the server is not responding on the network at all, mount fails
    the mount request immediately.
    
    Users might find it more useful if mount retried in both cases.
    
    Note that this change means attempting to mount using a misspelled
    server name will "hang" for the retry amount.  I suppose the error
    message isn't very helpful whether it fails immediately or waits
    a couple of minutes, though I imagine that an unreachable server is a
    much more common occurrence than a misspelling.

    sm-notify: Send fully-qualified and unqualified mon_names
    
    During any file locking interaction between an NFS client and server,
    the client tells the server what hostname it will use as the mon_name
    argument of the SM_NOTIFY request sent by the client when it reboots.
    This is the "caller_name" argument of an NLMPROC_LOCK request.
    
    The server, however, never tells the client what mon_name argument
    it will use when sending an SM_NOTIFY request.  In order to recognize
    the server, clients usually guess what mon_name the server might
    send, by using the server hostname provided by the user on the mount
    command line.
    
    Frequently, the user provides an unqualified server name on the mount
    command.  The server might then call the client back with a fully
    qualified domain name, which might not match in some cases.
    
    Solaris, and perhaps other implementations, attempt to mitigate this
    problem by sending two SM_NOTIFY requests to each peer: one with an
    unqualified mon_name argument, and one with a fully qualified mon_name.
    
    Implement such a scheme for sm-notify.
    
    Since my_name is almost always the fully-qualified hostname associated
    with the local system, just wiping the left-most '.' in the my_name
    argument and sending another SM_NOTIFY is nearly always sufficient.

    sm-notify: Use my_name when sending SM_NOTIFY requests
    
    The mon_name argument of an SM_NOTIFY request is a string that
    identifies the rebooting host.
    
    sm-notify should send the my_name provided by the local lockd at the
    time the remote was monitored, rather than cocking up a mon_name
    argument based on the present return value of gethostname(3).  If the
    local system's hostname happened to change after the last reboot, then
    the string returned by gethostname(3) will not be recognized by the
    remote.  Thus the remote will never initiate lock recovery for the
    original named host, possibly leaving stale locks.
    
    The existing behavior of using the -v command line option as the
    mon_name argument is preserved, but we now prevent sending an IP
    presentation address, as some non-Linux implementations don't
    recognize addresses as valid mon_names.

    The conversion to signed here could cause a hang on access by an unknown

    libtirpc however currently does an abort() in this case, which causes
    the program to crash and dump core.
    
    nfs-utils just uses these auth handles for the MNT protocol, so the
    group list doesn't make a lot of difference here. Add a new function
    that creates an auth handle with a supplemental gids list that consists
    only of the primary gid. Have nfs-utils use that function anywhere that
    it currently uses authunix_create_default. Also, have the caller
    properly check for a NULL return from that function.

    Fix a typo in commit 6d5ac3fa (nfsd: Disble NFS 4.1 functionality by
    default).
    
    We did not really intend to make NFSv4.0 support conditional on NFSv4.1
    being enabled.
