    rgw: fix usage trim call encoding
    
    Fixes: #2841.
    Usage trim operation was encoding the wrong op structure (usage read).
    Since the structures somewhat overlapped it somewhat worked, but user

    osd: peering: detect when log source osd goes down
    
    The Peering state has a generic check based on the prior set osds that
    will restart peering if one of them goes down (or one of the interesting
    down ones comes up).  The GetLog state, however, can pull the log from
    a peer that is not in the prior set if it got a notify from them (e.g., an
    osd in an old interval that was down when the prior set was calculated).
    If that osd goes down, we don't detect it and will block forward.
    
    Fix by adding a simple check in GetLog for the newest_update_osd going
    down.
    
    (BTW GetMissing does not suffer from this problem because
    peer_missing_requested is a subset of the prior set, so the Peering check
    is sufficient.)

    osd: set STRAY on pg load when non-primary
    
    The STRAY bit indicates that we should annouce ourselves to the primary,
    but it is only set in start_peering_interval().  We also need to set it
    initially, so that a PG that is loaded but whose role does not change
    (e.g., the stray replica stays a stray) will notify the primary.
    
    Observed:
     - osd starts up
     - mapping does not change, STRAY not set
     - does not announce to primary
     - primary does not re-check must_have_unfound, objects appear unfound
    
    Fix this by initializing STRAY when pg is loaded or created whenever we
    are not the primary.

    osd: peering: make Incomplete a Peering substate
    
    This allows us to still catch changes in the prior set that would affect
    our conclusions (that we are incomplete) and, when they happen, restart
    peering.
    
    Consider:
     - calc prior set, osd A is down
     - query everyone else, no good info
     - set down, go to Incomplete (previously WaitActingChange) state.
     - osd A comes back up (we do nothing)
     - osd A sends notify message with good info (we ignore)
    
    By making this a Peering substate, we catch the Peering AdvMap reaction,
    which will notice a prior set down osd is now up and move to Reset.

    PG::choose_acting() may return false and *not* request an acting set change
    if it can't find any suitable peers with enough info to recover.  In that
    case, we should move to Incomplete, not WaitActingChange, just like we do
    a bit lower in GetLog() if we have non-contiguous logs.  The state name is
    more accurate, and this is also needed to fix bug #2860.

    osd: fixing sharing of past_intervals on backfill restart
    
    We need to share past_intervals whenever we instantiate the PG on a peer.
    In the PG activation case, this is based on whether our peer_info[] value
    for that peer is dne().  However, the backfill code was updating the
    peer info (history) in the block preceeding the dne() check, which meant
    we never shared past_intervals in this case and the peer would have to
    chew through a potentially large number of maps if the PG has not been
    clean recently.
    
    Fix by checking dne() prior to the backfill block.  We still need to fill
    in the message later because it isn't yet instantiated.

    objecter: always resend linger registrations
    
    If a linger op (watch) is sent to the OSD and updates the object, and then
    the client loses the reply, it will resend the request.  The OSD will see
    that it is a dup, however, and not set up the in-memory session state for
    the watch.  This in turn will break the watch (i.e., notifies won't
    get delivered).
    
    Instead, always resend linger registration ops, so that we always have a
    unique reqid and do the correct session registeration for each session.
    
     * track the tid of the registation op for each LingerOp
     * mark registrations ops as should_resend=false; cancel as needed
     * when we send a new registration op, cancel the old one to ensure we
       ignore the reply.  This is needed becuase we resend linger ops on any
       pg change, not just a primary change.
     * drop the first_send arg to send_linger(), as we can now infer that
       from register_tid == 0.
    
    The bug was easily reproduced with ms inject socket failures = 500 and the
    test_stress_watch utility.

    osd: generate past intervals in parallel on boot
    
    Even though we aggressively share past_intervals with notifies etc, it is
    still possible for an osd to get buried behind a pile of old maps and need
    to generate these if it has been out of the cluster for a while.  This has
    happened to us in the past but, sadly, we did not merge the work then.
    On the bright side, this implementation is much much much cleaner than the
    old one because of the pg_interval_t helper we've since switched to.
    
    On bootup, we look at the intervals each pg needs and calclate the union,
    and then iterate over that map range.  The inner bit of the loop is
    functionally identical to PG::build_past_intervals(), keeping the per-pg
    state in the pistate struct.

    librbd: replace assign_bid with client id and random number
    
    The assign_bid method has issues with replay because it is a write
    that also returns data. This means that the replayed operation would
    return success, but no data, and cause a create to fail. Instead, let
    the client set the bid based on its global id and a random number.
    
    This only affects the creation of new images, since the bid is put
    into an opaque string as part of the object prefix.
    
    Keep the server side assign_bid around in case there are old clients
    still using it.

    Robustify ceph-rbdnamer and adapt udev rules
    
    Below is a patch which makes the ceph-rbdnamer script more robust and
    fixes a problem with the rbd udev rules.
    
    On our setup we encountered a symlink which was linked to the wrong rbd:
    
      /dev/rbd/mypool/myrbd -> /dev/rbd1
    
    While that link should have gone to /dev/rbd3 (on which a
    partition /dev/rbd3p1 was present).
    
    Now the old udev rule passes %n to the ceph-rbdnamer script, the problem
    with %n is that %n results in a value of 3 (for rbd3), but in a value of
    1 (for rbd3p1), so it seems it can't be depended upon for rbdnaming.
    
    In the patch below the ceph-rbdnamer script is made more robust and it
    now it can be called in various ways:
    
      /usr/bin/ceph-rbdnamer /dev/rbd3
      /usr/bin/ceph-rbdnamer /dev/rbd3p1
      /usr/bin/ceph-rbdnamer rbd3
      /usr/bin/ceph-rbdnamer rbd3p1
      /usr/bin/ceph-rbdnamer 3
    
    Even with all these different styles of calling the modified script, it
    should now return the same rbdname. This change "has" to be combined
    with calling it from udev with %k though.
    
    With that fixed, we hit the second problem. We ended up with:
    
      /dev/rbd/mypool/myrbd -> /dev/rbd3p1
    
    So the rbdname was symlinked to the partition on the rbd instead of the
    rbd itself. So what probably went wrong is udev discovering the disk and
    running ceph-rbdnamer which resolved it to myrbd so the following
    symlink was created:
    
      /dev/rbd/mypool/myrbd -> /dev/rbd3
    
    However partitions would be discovered next and ceph-rbdnamer would be
    run with rbd3p1 (%k) as parameter, resulting in the name myrbd too, with
    the previous correct symlink being overwritten with a faulty one:
    
      /dev/rbd/mypool/myrbd -> /dev/rbd3p1
    
    The solution to the problem is in differentiating between disks and
    partitions in udev and handling them slightly differently. So with the
    patch below partitions now get their own symlinks in the following style
    (which is fairly consistent with other udev rules):
    
      /dev/rbd/mypool/myrbd-part1 -> /dev/rbd3p1
    
    Please let me know any feedback you have on this patch or the approach
    used.

    mon/MonitorStore: always O_TRUNC when writing states
    
    It is possible for a .new file to already exist, potentially with a
    larger size.  This would happen if:
    
     - we were proposing a different value
     - we crashed (or were stopped) before it got renamed into place
     - after restarting, a different value was proposed and accepted.
    
    This isn't so unlikely for the log state machine, where we're
    aggregating random messages.  O_TRUNC ensure we avoid getting the tail
    end of some previous junk.
    
    I observed #2593 and found that a logm state value had a larger size on
    one mon (after slurping) than the others, pointing to put_bl_sn_map().
    
    While we are at it, O_TRUNC put_int() too; the same type of bug is
    possible there, too.

    If a new pipe/socket is taking over an existing session, it should also
    take over the Connection* associated with the existing session.  Because

    Clean up the comments a bit while we're here.
    
    This affects MDS<->client sessions when reconnecting after a socket fault.

    info indexed by bucket name, which is bad.

    msgr: choose incoming connection if ours is STANDBY
    
    If the connect_seq matches, but our existing connection is in STANDBY, take
    the incoming one.  Otherwise, the other end will wait indefinitely for us
    to connect but we won't.
    
    Alternatively, we could "win" the race and trigger a connection by sending
    a keepalive (or similar), but that is more work; we may as well accept the
    incoming connection we have now.
    
    This removes STANDBY from the acceptable WAIT case states.  It also keeps
    responsibility squarely on the shoulders of the peer with something to
    deliver.
    
    Without this patch, a 3-osd vstart cluster with
    'ms inject socket failures = 100' and rados bench write -b 4096 would start
    generating slow request warnings after a few minutes due to the osds
    failing to connect to each other.  With the patch, I complete a 10 minute
    run without problems.

    msgr: preserve incoming message queue when replacing pipes
    
    If we replace an existing pipe with a new one, move the incoming queue
    of messages that have not yet been dispatched over to the new Pipe so that
    they are not lost.  This prevents messages from being lost.
    
    Alternatively, we could set in_seq = existing->in_seq - existing->in_qlen,
    but that would make the other end resend those messages, which is a waste
    of bandwidth.
    
    Very easy to reproduce the original bug with 'ms inject socket failures'.

    msgr: move incoming queue to separate class
    
    This extricates the incoming queue and its funky relationship with
    DispatchQueue from Pipe and moves it into IncomingQueue.  There is now a
    single IncomingQueue attached to each Pipe.  DispatchQueue is now no
    longer tied to Pipe.
    
    This modularizes the code a bit better (tho that is still a work in
    progress) and (more importantly) will make it possible to move the
    incoming messages from one pipe to another in accept().

    msgr: make D_CONNECT constant non-zero, fix ms_handle_connect() callback
    
    A while ago we inadvertantly broke ms_handle_connect() callbacks because
    of a check for m being non-zero in the dispatch_entry() thread.  Adjust the
    enums so that they get delivered again.
    
    This fixes hangs when, for example, the ceph tool sends a command, gets a
    connection reset, and doesn't get the connect callback to resend after
    reconnecting to a new monitor.

    Otherwise, we will throw out that information and falsely trigger a
