    qa/workunits/cephtool/test.sh: fix thrash (ultimate)

    Keep the osd trash test to ensure it is a valid command but make it a
    noop by giving it a zero argument (meaning thrash 0 OSD maps).

    Remove the loops that were added after the command in an attempt to wait
    for the cluster to recover and not pollute the rest of the tests. Actual
    testing of osd thrash would require a dedicated cluster because it the
    side effects are random and it is unnecessarily difficult to ensure they
    are finished.

    ReplicatedPG:start_flush send a second delete

    Suppose we start with the following in the cache pool:

    30:[29,21,20,15,10,4]:[22(21), 15(15,10), 4(4)]+head

    The object doesn't exist at 29 or 20.

    First, we flush 4 leaving the backing pool with:

    3:[]+head

    Then, we begin to flush 15 with a delete with snapc 4:[4] leaving the
    backing pool with:

    4:[4]:[4(4)]

    Then, we finish flushing 15 with snapc 9:[4] with leaving the backing
    pool with:

    9:[4]:[4(4)]+head

    Next, snaps 10 and 15 are removed causing clone 10 to be removed leaving
    the cache with:

    30:[29,21,20,4]:[22(21),4(4)]+head

    We next begin to flush 22 by sending a delete with snapc 4(4) since
    prev_snapc is 4 <---------- here is the bug

    The backing pool ignores this request since 4 < 9 (ORDERSNAP) leaving it
    with:

    9:[4]:[4(4)]

    Then, we complete flushing 22 with snapc 19:[4] leaving the backing pool
    with:

    19:[4]:[4(4)]+head

    Then, we begin to flush head by deleting with snapc 22:[21,20,4] leaving
    the backing pool with:

    22[21,20,4]:[22(21,20), 4(4)]

    Finally, we flush head leaving the backing pool with:

    30:[29,21,20,4]:[22(21*,20*),4(4)]+head

    When we go to flush clone 22, all we know is that 22 is dirty, has snaps
    [21], and 4 is clean. As part of flushing 22, we need to do two things:
    1) Ensure that the current head is cloned as cloneid 4 with snaps [4] by
    sending a delete at snapc 4:[4].
    2) Flush the data at snap sequence < 21 by sending a copyfrom with snapc
    20:[20,4].

    Unfortunately, it is possible that 1, 1&2, or 1 and part of the flush
    process for some other now non-existent clone have already been
    performed.  Because of that, between 1) and 2), we need to send
    a second delete ensuring that the object does not exist at 20.

    librbd: fix crash using clone of flattened image

    The crash occurs due to ImageCtx->parent->parent being uninitialized,
    since the inital open_parent() -> open_image(parent) ->
    ictx_refresh(parent) occurs before ImageCtx->parent->snap_id is set,
    so refresh_parent() is not called to open an ImageCtx for the parent
    of the parent. This leaves the ImageCtx->parent->parent NULL, but the
    rest of ImageCtx->parent updated to point at the correct parent snapshot.

    Setting the parent->snap_id earlier has some unintended side effects
    currently, so for now just call refresh_parent() during
    open_parent(). This is the easily backportable version of the
    fix. Further patches can clean up this whole initialization process.

    osd/PG: fix crash from second backfill reservation rejection

    If we get more than one reservation rejection we should ignore them; when
    we got the first we already sent out cancellations.  More importantly, we

    When we use an unordered_map the encoding order is non-deterministic,
    which is problematic for OSDMap.  Construct an ordered map<> on encode
    and use that.  This lets us keep the hash table for lookups in the general
    case.

     - the client session resets
     - we go back to process the message later and discard
       - _ms_dispatch returns false, but nobody drops the msg ref

    Since we call _ms_dispatch() a lot internally, we need to always return
    true when we are an internal caller.

    erasure-code: preload the jerasure plugin variant (sse4,sse3,generic)

    The preloading of the jerasure plugin ldopen the plugin that is in
    charge of selecting the variant optimized for the
    CPU (sse4,sse3,generic). The variant plugin itself is not loaded because
    it does not happen at load() but when the factory() method is called.

    The JerasurePlugin::preload method is modified to call the factory()
    method to load jerasure_sse4 or jerasure_sse3 or jerasure_generic as a
    side effect.

    Indirectly loading another plugin in the factory() method is error prone
    and should be moved to the load() method instead. This change should be

    Fix set_alloc_hint op cause KeyValueStore crash problem

    Now KeyValueStore doesn't support set_alloc_hit op, the implementation of
    _do_transaction need to consider decoding the arguments. Otherwise, the
    arguments will be regarded as the next op.

    Fix the same problem for MemStore.

    erasure-code: preload the jerasure plugin (firefly)

    erasure-code: preload the jerasure plugin

    Load the jerasure plugin when ceph-osd starts to avoid the following
    scenario:

    * ceph-osd-v1 is running but did not load jerasure

    * ceph-osd-v2 is installed being installed but takes time : the files
      are installed before ceph-osd is restarted

    * ceph-osd-v1 is required to handle an erasure coded placement group and
      loads jerasure (the v2 version which is not API compatible)

    * ceph-osd-v1 calls the v2 jerasure plugin and does not reference the
      expected part of the code and crashes

    Although this problem shows in the context of teuthology, it is unlikely
    to happen on a real cluster because it involves upgrading immediately
    after installing and running an OSD. Once it is backported to firefly,
    it will not even happen in teuthology tests because the upgrade from
    firefly to master will use the firefly version including this fix.

    While it would be possible to walk the plugin directory and preload
    whatever it contains, that would not work for plugins such as jerasure
    that load other plugins depending on the CPU features, or even plugins
    such as isa which only work on specific CPU.

    Work around an apparent binding bug (GCC 4.8).

    A reference to h->seq passed to std::pair ostensibly could not bind
    because the header structure is packed.  At first this looked like
    a more general unaligned access problem, but the only location the
    compiler rejects is a false positive.

    common/config.cc: allow integer values to be parsed as SI units

    We are allowing this for all and any integer values; that is, OPT_INT,
    OPT_LONGLONG, OPT_U32 and OPT_U64.

    It's on the user to use appropriate units.  For instance, the user should
    not use 'E(xabyte)' when setting a signed int, and use his best judgment
    when setting options that, for instance, ought to receive seconds.

    osd: introduce simple sleep during scrub

    This option is similar to osd_snap_trim_sleep: simply inject an optional
    sleep in the thread that is doing scrub work.  This is a very kludgey and
    coarse knob for limiting the impact of scrub on the cluster, but can help
    until we have a more robust and elegant solution.

    Only sleep if we are in the NEW_CHUNK state to avoid delaying processing of
    an in-progress chunk.  In this state nothing is blocked on anything.
    Conveniently, chunky_scrub() requeues itself for each new chunk.

    osd: prevent pgs from getting too far ahead of the min pg epoch

    Bound the range of PG epochs between the slowest and fastest pg
    (epoch-wise) with 'osd map max advance'.  This value should be set to
    something less than 'osd map cache size' so that the maps we are
    processing will be in memory as many PGs advance forward in time in
    loose synchrony.

    This is part of the solution to #7576.

    The main 'operation' know not to send any body for HEAD requests.

    However for errors, this was not the case, the formatter would be

    For the FastCGI case it doesn't seem to be an issue, it's possible
    that the webserver (apache/lighttpd/...) cleans up the response
    into shape.

    Add rbdcache max dirty object option

    Librbd will calculate max dirty object according to rbd_cache_max_size, it
    doesn't suitable for every case. If user set image order 24, the calculating
    result is too small for reality. It will increase the overhead of trim call
    which is called each read/write op.

    Now we make it as option for tunning, by default this value is calculated.

    Fix potential null ponter deref, move check for 'order != NULL'

    and b) to leave function as early as possible if check fails.

    [src/librbd/internal.cc:843] -> [src/librbd/internal.cc:865]: (warning)
     Possible null pointer dereference: order - otherwise it is redundant

    os/LFNIndex: only consider alt xattr if nlink > 1

    If we are doing a lookup, the main xattr fails, we'll check if there is an
    alt xattr.  If it exists, but the nlink on the inode is only 1, we will
    kill the xattr.  This cleans up the mess left over by an incomplete
    lfn_unlink operation.

    This resolves the problem with an lfn_link to a second long name that
    hashes to the same short_name: we will ignore the old name the moment the
    old link goes away.

    os/LFNIndex: remove alt xattr after unlink

    After we unlink, if the nlink on the inode is still non-zero, remove the
    alt xattr.  We can *only* do this after the rename or unlink operation
    because we don't want to leave a file system link in place without the
    matching xattr; hence the fsync_dir() call.

    Note that this might leak an alt xattr if we happen to fail after the
    rename/unlink but before the removexattr is committed.  We'll fix that
    next.

    os/LFNIndex: handle long object names with multiple links (i.e., rename)

    When we rename an object (collection_move_rename) to a different name, and
    the name is long, we run into problems because the lfn xattr can only track
    a single long name linking to the inode.  For example, suppose we have

    foobar -> foo_123_0 (attr: foobar) where foobar hashes to 123.

    At first, collection_add could only link a file to another file in a
    different collection with the same name. Allowing collection_move_rename
    to rename the file, however, means that we have to convert:

    col1/foobar -> foo_123_0 (attr: foobar)

    to

    col1/foobaz -> foo_234_0 (attr: foobaz)

    This is a problem because if we link, reset xattr, unlink we end up with

    col1/foobar -> foo_123_0 (attr: foobaz)

    if we restart after we reset the attr.  This will cause the initial foobar
    lookup to since the attr doesn't match, and the file won't be able to be
    looked up.

    Fix this by allow *two* (long) names to link to the same inode.  If we
    lfn_link a second (different) name, move the previous name to the "alt"
    xattr and set the new name.  (This works because link is always followed
    by unlink.)  On lookup, check either xattr.

    Don't even bother to remove the alt xattr on unlink.  This works as long
    as the old name and new name don't hash to the same shortname and end up
    in the same LFN chain.  (Don't worry, we'll fix that next.)

    test/cli-integration/rbd: fix trailing space

    Newer versions of json.tool remove the trailing ' ' after the comma.  Add
    it back in with sed so that the .t works on both old and new versions, and
    so that we don't have to remove the trailing spaces from all of the test
    cases.

    mon: include 'max avail' in df output

    Include an estimate of the maximum writeable space for each pool.  Note
    that this value is a conservative estimate for that pool based on the
    most-full OSD.  It is also potentially misleading as it is the available
    space if *all* new data were written to this pool; one cannot (generally)
    add up the available space for all pools.

    osd/ReplicatedPG: requeue cache full waiters if no longer writeback

    If the cache is full, we block some requests, and then we change the
    cache_mode to something else (say, forward), the full waiters don't get
    requeued until the cache becomes un-full.  In the meantime, however, later
    requests will get processed and redirected, breaking the op ordering.

    Fix this by requeueing any full waiters if we see that the cache_mode is
    not writeback.

    qa/workunits: cephtool: split into properly indented functions

    The test was a big sequence of commands being run and it has been growing
    organically for a while, even though it has maintained a sense of
    locality with regard to the portions being tested.

    This patch intends to split the commands into functions, allowing for a
    better semantic context and easier expansion.  On the other hand, this
    will also allow us to implement mechanisms to run specific portions of
    the test instead of always having to run the whole thing just to test a
    couple of lines down at the bottom (or have to creatively edit the test).

    osd/ReplicatedPG: greedily take write_lock for copyfrom finish, snapdir

    In the cases where we are taking a write lock and are careful
    enough that we know we should succeed (i.e, we assert(got)),
    use the get_write_greedy() variant that skips the checks for
    waiters (be they ops or backfill) that are normally necessary
    to avoid starvation.  We don't care about staration here
    because our op is already in-progress and can't easily be
    aborted, and new ops won't start because they do make those
    checks.

    osd: allow greedy get_write() for ObjectContext locks

    There are several lockers that need to take a write lock
    because there is an operation that is already in progress and
    know it is safe to do so.  In particular, they need to skip
    the starvation checks (op waiters, backfill waiting).

    erasure-code: create default profile if necessary

    After an upgrade to firefly, the existing Ceph clusters do not have the
    default erasure code profile. Although it may be created with

       ceph osd erasure-code-profile set default

    it was not included in the release notes and is confusing for the
    administrator.

    The *osd pool create* and *osd crush rule create-erasure* commands are
    modified to implicitly create the default erasure code profile if it is
    not found.

    In order to avoid code duplication, the default erasure code profile
    code creation that happens when a new firefly ceph cluster is created is
    encapsulated in the OSDMap::get_erasure_code_profile_default method.

    Conversely, handling the pending change in OSDMonitor is not
    encapsulated in a function but duplicated instead. If it was a function
    the caller would need a switch to distinguish between the case when goto
    wait is needed, or goto reply or proceed because nothing needs to be
    done. It is unclear if having a function would lead to smaller or more
    maintainable code.
