LU-12394 llite: Fix extents_stats

Patch 32517 from LU-8066 changed:
        (1 << LL_HIST_START << i)

To:

        BIT(LL_HIST_START << i)

But these are not equivalent because this changes the order
of operations.  The earlier one does the operations in this
order:
        (1 << LL_HIST_START) << i

The new one is this order:
        1 << (LL_HIST_START << i)

Which is quite different, as it's left shifting
LL_HIST_START directly, and LL_HIST_START is a number of
bits.

The goal is really just to start with BIT(LL_HIST_START)
and left shift by one (going from 4K, to 8K, etc) each
time, so just use:
        BIT(LL_HIST_START + i)

The result of this was that all i/os over 8K were placed in
the 4K-8K stat bucket, because the loop exited early.

Also add mmap'ed reads & writes to extents_stats.

Add test for extents_stats.

                     to debugfs")

LU-12336 build: Update ZFS version to 0.8.1

New Features 0.8.0

* Native encryption #5769 - The encryption property enables the
creation of encrypted filesystems and volumes. The aes-256-ccm
algorithm is used by default. Per-dataset keys are managed with zfs
load-key and associated subcommands.

* Raw encrypted 'zfs send/receive' #5769 - The zfs send -w option
allows an encrypted dataset to be sent and received to another pool
without decryption. The received dataset is protected by the original
user key from the sending side. This allows datasets to be efficiently
backed up to an untrusted system without fear of the data being
compromised.

* Device removal #6900 - This feature allows single and mirrored
top-level devices to be removed from the storage pool with zpool
remove. All data is copied in the background to the remaining
top-level devices and the pool capacity is reduced accordingly.

* Pool checkpoints #7570 - The zpool checkpoint subcommand allows
you to preserve the entire state of a pool and optionally revert back
to that exact state. It can be thought of as a pool wide snapshot.
This is useful when performing complex administrative actions which
are otherwise irreversible (e.g. enabling a new feature flag,
destroying a dataset, etc).

* Pool TRIM #8419 - The zpool trim subcommand provides a way to
notify the underlying devices which sectors are no longer allocated.
This allows an SSD to more efficiently manage itself and helps prevent
performance from degrading. Continuous background trimming can be
enabled via the new autotrim pool property.

* Pool initialization #8230 - The zpool initialize subcommand writes
a pattern to all the unallocated space. This eliminates the first
access performance penalty, which may exist on some virtualized
storage (e.g. VMware VMDKs).

* Project accounting and quota #6290 - This features adds project
based usage accounting and quota enforcement to the existing space
accounting and quota functionality. Project quotas add an additional
dimension to traditional user/group quotas. The zfs project and zfs
projectspace subcommands have been added to manage projects, set quota
limits and report on usage.

* Channel programs #6558 - The zpool program subcommand can be used
to perform compound ZFS administrative actions via Lua scripts in a
sandboxed environment (with time and memory limits).

* Pyzfs #7230 - The new pyzfs library is intended to provide a
stable interface for the programmatic administration of ZFS. This
wrapper provides a one-to-one mapping for the libzfs_core API
functions, but the signatures and types are more natural to Python.

* Python 3 compatibility #8096 - The arcstat, arcsummary, and
dbufstat utilities have been updated to be compatible with Python 3.

* Direct IO #7823 - Adds support for Linux's direct IO interface.

Performance

* Sequential scrub and resilver #6256 - When scrubbing or
resilvering a pool the process has been split into two phases. The
first phase scans the pool metadata in order to determine where the
data blocks are stored on disk. This allows the second phase to issue
scrub I/O as sequentially as possible, greatly improving performance.

* Allocation classes #5182 - Allows a pool to include a small number
of high-performance SSD devices that are dedicated to storing specific
types of frequently accessed blocks (e.g. metadata, DDT data, or small
file blocks). A pool can opt-in to this feature by adding a special or
dedup top-level device.

* Administrative commands #7668 - Improved performance due to
targeted caching of the metadata required for administrative commands
like zfs list and zfs get.

* Parallel allocation #7682 - The allocation process has been
parallelized by creating multiple "allocators" per-metaslab group.
This results in improved allocation performance on high-end systems.

* Deferred resilvers #7732 - This feature allows new resilvers to be
postponed if an existing one is already in progress. By waiting for
the running resilver to complete redundancy is restored as quickly as
possible.

* ZFS Intent Log (ZIL) #6566 - New log blocks are created and issued
while there are still outstanding blocks being serviced by the
storage, effectively reducing the overall latency observed by the
application.

* Volumes #8615 - When a pool contains a large number of volumes
they are more promptly registered with the system and made available
for use after a zpool import.

* QAT #7295 #7282 #6767 - Support for accelerated SHA256 checksums,
AES-GCM encryption, and the new QAT Intel(R) C62x Chipset / Atom(R)
C3000 Processor Product Family SoC.

Changes in Behavior

* Relaxed (ref)reservation constraints on volumes, they may now be
set larger than the volume size.

* The arcstat.py, arc_summary.py, and dbufstat.py commands have been
renamed arcstat, arc_summary, and dbufstat respectively.

* The SPL source is now included in the ZFS repository removing the
need for separate packages.

* The dedupditto pool property and zfs send -D option have been
deprecated and will be removed in a future release.

LU-12402 lnet: handle recursion in resend

When we're resending a message we have to decommit it first. This
could potentially result in another message being picked up from the
queue and sent, which could fail immediately and be finalized, causing
recursion. This problem was observed when a router was being shutdown.

This patch uses the same mechanism used in lnet_finalize() to limit
recursion. If a thread is already finalizing a message and it gets
into path where it starts finalizing a second, then that message
is queued and handled later.

LU-10931 lnet: handle unlink before send completes

If LNetMDUnlink() is called on an md with md->md_refcount > 0 then
the eq callback isn't called.
There is a scenario where the response times out before the send
completes. So we have a refcount on the MD. The Unlink callback gets
dropped on the floor. Send completes, but because we've already timed
out, the REPLY for the GET is dropped. Now we're left with a peer
that is in the following state:
LNET_PEER_MULTI_RAIL
LNET_PEER_DISCOVERING
LNET_PEER_PING_SENT
But no more events are coming to it, and the discovery never
completes.

This scenario can get RPCs stuck as well if the response times out
before the send completes.

The solution is to set the event status to -ETIMEDOUT to inform
the send event handler that it should not expect a reply

LU-12542 handles: discard h_owner in favour of h_ops

lustre_handles assigned a 64bit unique identifier (a 'cookie') to
objects of various types and stored them in a hash table, allowing
them to be accessed by the cookie.

There is a facility for type checking by recording an 'owner' for each
object, and checking the owner on lookup. Unfortunately this is not
used - owner is always zero for the client.

Each object also contains an h_ops pointer which can be used to
reliably identify an owner.

So discard h_owner, pass and 'ops' pointer to class_handle2object(),
and only return objects for which the h_ops matches.

Note: this h_owner is now quiet different from the similar h_owner
in the server code.  When the server code is merged the "med" pointer
should be stored in the "mfd" and validated separately.

This reduces the size of the portals_handle by one pointer, which
benefits various other structures including struct ldlm_lock which can
be very populous and so is best keep small.

LU-12565 obdecho: use bit-locking in echo_client.

The ep_lock used by echo client causes lockdep to complain.
Multiple locks of the same class are taken concurrently which
appear to lockdep to be prone to deadlocking, and can fill up
lockdep's fixed size stack for locks.

As ep_lock is taken on multiple pages always in ascending page order,
deadlocks don't happen, so this is a false-positive.

The function of the ep_lock is the same as thats for page_lock(),
which is implemented as a bit-lock using wait_on_bit().  lockdep
cannot see these locks, and doesn't really need to.

So convert ep_lock to a simple bit-lock using wait_on_bit for
waiting. This provides similar functionality, matches how page_lock()
works, and avoids lockdep problems.

have allocated another object for the same file and unlinked

To reproduce the race, introduced cfs_race_wait() and
cfs_race_wakeup(): cfs_race_wait() will cause the thread that
calls it wait on the race; while cfs_race_wakeup() will wake

LU-12586 lov: Correct write_intent end for trunc

When instantiating a layout, the server interprets the
write intent from the client as the range [start, end), not
including the last byte.

This is correct for writes because the last byte given for
a write is actually 'endpos', the resulting file pointer
position, and so is not included.

However, truncate is specifiying a size, not an endpos, so
truncate is [start, size].  To make this work with the
[start, end) processing for write_intents, we have to add
1 to the size when sending a write intent.

Without this, a truncate operation to the first byte of a
new layout component fails silently because the component
is not instantiated.

LU-12568 lnet: Defer rspt cleanup when MD queued for unlink

When an MD is queued for unlink its lnet_libhandle is invalidated so
that future lookups of the MD fail. As a result, the monitor thread
cannot detach the response tracker from such an MD, and instead must
wait for the remaining operations on the MD to complete before it can
safely free the response tracker and remove it from the list. Freeing
the memory while there are pending operations on the MD can result
in a use after free situation when the final operation on the MD
completes and we attempt to remove the response tracker from the MD
via the lnet_msg_detach_md()->lnet_detach_rsp_tracker() call chain.

Here we introduce zombie lists for such response trackers. This will
allow us to also handle the case where there are response trackers
on the monitor queue during LNet shutdown. In this instance the
zombie response trackers will be freed when either all the operations
on the MD have completed (this free'ing is performed by
lnet_detach_rsp_tracker()) or after the LND Nets have shutdown since
we are ensured there will not be any more operations on the
associated MDs (this free'ing is performed by
lnet_clean_zombie_rstqs()).

Three other small changes are included in this patch:
 - When deleting the response tracker from the monitor's list we
   should use list_del() rather than list_del_init() since we'll
   be freeing the response tracker after removing it from the list.
 - Perform a single ktime_get() call for each local queue.
 - Move the check of whether the local queue is empty outside of
   the net lock.

LU-11617 mdc: fix possible deadlock in chlg_open()

Lockdep reports a possible deadlock between chlg_open() and
mdc_changelog_cdev_init()

mdc_changelog_cdev_init() takes chlg_registered_dev_lock and then
calls misc_register() which takes misc_mtx.
chlg_open() is called while misc_mtx is held, and tries to take
chlg_registered_dev_lock.
If these two functions race, a deadlock can occur as each thread will
hold one of the locks while trying to take the other.

chlg_open() does not need to take a lock.  It only uses the
lock to stablize a list while looking for the matching
chlg_registered_dev, and this can be found directly by examining
file->private_data.

So remove chlg_obd_get(), and use file->private_data to find the
obd_device.
Also ensure the device is fully initialized before calling
misc_register().  This means setting up some list linkage before the
call, and tearing it down if there is an error.

LU-11023 quota: remove quota pool ID

Remove pool ID support in quotas as it is
totally unused. It is also needed to start
implementation of quota pools that may
include 2 type of slaves - OST's or MDT's.
At the first stage quota pools will be the
mirror of LOD pools. Further when/if MDT pools
will appear, these could be aslo used as quota
pools.
The main part of quota pool's is not
changed because it will be used for new quota
pools. Remove qmt's pool hash as pool's look up
mainly will be performed by OST/MDT index and
all code connected with quota pool ID.

LU-12595 lnet: Return EHOSTUNREACH for unreachable gateway

Commit 43b35351e9ca258773e89c2d68047e939fb822fb contains a flaw in
that it shouldn't be a fatal error to encounter an unreachable
gateway when parsing routes. Parsing should continue in case there
are any valid, reachable routes that are being added. Returning EINAL

We could not use vmpage refcount to check whether page could be
released because it break invalidate_complete_page2():

See comments:
/*
 * This is like invalidate_complete_page(), except it ignores the page's
 * refcount.  We do this because invalidate_inode_pages2() needs stronger
 * invalidation guarantees, and cannot afford to leave pages behind because
 * shrink_page_list() has a temp ref on them, or because they're transiently
 * sitting in the lru_cache_add() pagevecs.
 */

So checking refcount > 3 might be wrong here, one common
case is page might be transiently in lru_cache_add().

Since we have checked whether vmpage is used by cl_page later in the
function, and vmpage will be locked before called, it should be safe
to remove vmpage refcount check.

One of problem currently is following DIO will mostly
fall back to Buffer IO:

 $ dd if=/dev/zero of=data bs=1M count=1
 $ dd if=/dev/zero of=data bs=1M count=1 oflag=direct conv=notrunc

Which is because DIO will firstly try to writeback and invalidate
clean page which fail because vmpage refcount could be 4 here.

Function calls come from linux-3.10.0-957.1.3.el7.x86_64:

|->generic_file_direct_write()
  |->filemap_write_and_wait_range()
    |->invalidate_inode_pages2_range()
          |->invalidate_complete_page2() If a page can not be invalidated,
 return 0 to fall back to buffered write.
                |->try_to_release_page()
  |->ll_releasepage()
return 0 becuase of vmpage count is 4 > 3

LU-12472 tests: update sanity-krb5.sh

With current Lustre version, some behaviors have changed.

When a user tries to access Lustre without valid Kerberos credentials,
access is denied, and the key generated in the user's session keyring
is marked as revoked. This key must be unlinked so that further
access with valid Kerberos credentials regenerates a new, valid key in
the user's session keyring.

When Kerberos credentials presented by the user cannot be validated
on server side because the lsvcgssd daemon is down, client's request
immediately fails instead of being blocked until lsvcgssd daemon
is up and runnning again.

*gssd daemon is automatically started in the background, no need for a
'&' on the command line.
