Tom Caputi 9b8407638d Send / Recv Fixes following b52563
This patch fixes several issues discovered after
the encryption patch was merged:

* Fixed a bug where encrypted datasets could attempt
  to receive embedded data records.

* Fixed a bug where dirty records created by the recv
  code wasn't properly setting the dr_raw flag.

* Fixed a typo where a dmu_tx_commit() was changed to
  dmu_tx_abort()

* Fixed a few error handling bugs unrelated to the
  encryption patch in dmu_recv_stream()

Brian Behlendorf 133a5c6598 zimport.sh: Allow custom pool create options
Allow custom options to be passed to 'zpool create` when creating
a new pool.

Normally zimport.sh is intented to prevent accidentally introduced
incompatibilities so we want the default behavior.  However, when
introducing a known incompatibility with a feature flag we need a
way to disable the feature.  By adding a line like the following
to the commit message the feature can be disabled allowing the
pool to be compatibile with older versions.

TEST_ZIMPORT_CREATE_OPTIONS="-o feature@encryption=disabled"

* Additionally fix /dev/nul -> /dev/null typo and minor white space
  formating issues.

* Updated fail function to print a message and exit with 1 for use
  by the buildbot.

* Silence warnings when zlib_inflate / zlib_default modules don't
  exist.  This can happen when they're build in to the kernel.

LOLi 9000a9fac9 Disable mount(8) canonical paths in do_mount()
By default the mount(8) command, as invoked by 'zfs mount', will try
to resolve any path parameter in its canonical form: this could lead
to mount failures when the cwd contains a symlink having the same name
of the dataset being mounted.

LOLi f763c3d1df Fix range locking in ZIL commit codepath
Since OpenZFS 7578 (1b7c1e5) if we have a ZVOL with logbias=throughput
we will force WR_INDIRECT itxs in zvol_log_write() setting itx->itx_lr
offset and length to the offset and length of the BIO from
zvol_write()->zvol_log_write(): these offset and length are later used
to take a range lock in zillog->zl_get_data function: zvol_get_data().

Now suppose we have a ZVOL with blocksize=8K and push 4K writes to
offset 0: we will only be range-locking 0-4096. This means the
ASSERTion we make in dbuf_unoverride() is no longer valid because now
dmu_sync() is called from zilog's get_data functions holding a partial
lock on the dbuf.

Fix this by taking a range lock on the whole block in zvol_get_data().

sckobras d49d9c2bdc vdev_id: implement slot numbering by port id
With HPE hardware and hpsa-driven SAS adapters, only a single phy is
reported, but no individual per-port phys (ie. no phy* entry below
port_dir), which breaks topology detection in the current sas_handler
code. Instead, slot information can be derived directly from the port
number. This change implements a new slot keyword "port" similar to
"id" and "lun", and assumes a default phy/port of 0 if no individual
phy entry can be found. It allows to use the "sas_direct" topology with
current HPE Dxxxx and Apollo 45xx JBODs.

Tom Caputi b525630342 Native Encryption for ZFS on Linux
This change incorporates three major pieces:

The first change is a keystore that manages wrapping
and encryption keys for encrypted datasets. These
commands mostly involve manipulating the new
DSL Crypto Key ZAP Objects that live in the MOS. Each
encrypted dataset has its own DSL Crypto Key that is
protected with a user's key. This level of indirection
allows users to change their keys without re-encrypting
their entire datasets. The change implements the new
subcommands "zfs load-key", "zfs unload-key" and
"zfs change-key" which allow the user to manage their
encryption keys and settings. In addition, several new
flags and properties have been added to allow dataset
creation and to make mounting and unmounting more
convenient.

The second piece of this patch provides the ability to
encrypt, decyrpt, and authenticate protected datasets.
Each object set maintains a Merkel tree of Message
Authentication Codes that protect the lower layers,
similarly to how checksums are maintained. This part
impacts the zio layer, which handles the actual
encryption and generation of MACs, as well as the ARC
and DMU, which need to be able to handle encrypted
buffers and protected data.

The last addition is the ability to do raw, encrypted
sends and receives. The idea here is to send raw
encrypted and compressed data and receive it exactly
as is on a backup system. This means that the dataset
on the receiving system is protected using the same
user key that is in use on the sending side. By doing
so, datasets can be efficiently backed up to an
untrusted system without fear of data being
compromised.

Brian Behlendorf c25b8f99f8 Simplify threads, mutexs, cvs and rwlocks
* Simplify threads, mutexs, cvs and rwlocks

* Update the zk_thread_create() function to use the same trick
  as Illumos.  Specifically, cast the new pthread_t to a void
  pointer and return that as the kthread_t *.  This avoids the
  issues associated with managing a wrapper structure and is
  safe as long as the callers never attempt to dereference it.

* Update all function prototypes passed to pthread_create() to
  match the expected prototype.  We were getting away this with
  before since the function were explicitly cast.

* Replaced direct zk_thread_create() calls with thread_create()
  for code consistency.  All consumers of libzpool now use the
  proper wrappers.

* The mutex_held() calls were converted to MUTEX_HELD().

* Removed all mutex_owner() calls and retired the interface.
  Instead use MUTEX_HELD() which provides the same information
  and allows the implementation details to be hidden.  In this
  case the use of the pthread_equals() function.

* The kthread_t, kmutex_t, krwlock_t, and krwlock_t types had
  any non essential fields removed.  In the case of kthread_t
  and kcondvar_t they could be directly typedef'd to pthread_t
  and pthread_cond_t respectively.

* Removed all extra ASSERTS from the thread, mutex, rwlock, and
  cv wrapper functions.  In practice, pthreads already provides
  the vast majority of checks as long as we check the return
  code.  Removing this code from our wrappers help readability.

* Added TS_JOINABLE state flag to pass to request a joinable rather
  than detached thread.  This isn't a standard thread_create() state
  but it's the least invasive way to pass this information and is
  only used by ztest.

sanjeevbagewadi 21df134f4c zio_dva_throttle_done() should allow zinjected ZIO
If fault injection is enabled, the ZIO_FLAG_IO_RETRY could be set by
zio_handle_device_injection() to generate the FMA events and update
stats. Hence, ignore the flag and process such zios.

A better fix would be to add another flag in the zio_t to indicate that
the zio is failed because of a zinject rule. However, considering the
fact that we do this in debug bits, we could do with the crude check
using the global flag zio_injection_enabled which is set to 1 when
zinject records are added.

Brian Behlendorf 46364cb2f3 Add libtpool (thread pools)
OpenZFS provides a library called tpool which implements thread
pools for user space applications.  Porting this library means
the zpool utility no longer needs to borrow the kernel mutex and
taskq interfaces from libzpool.  This code was updated to use
the tpool library which behaves in a very similar fashion.

Porting libtpool was relatively straight forward and minimal
modifications were needed.  The core changes were:

* Fully convert the library to use pthreads.
* Updated signal handling.
* lmalloc/lfree converted to calloc/free
* Implemented portable pthread_attr_clone() function.

Finally, update the build system such that libzpool.so is no
longer linked in to zfs(8), zpool(8), etc.  All that is required
is libzfs to which the zcommon soures were added (which is the way
it always should have been).  Removing the libzpool dependency
resulted in several build issues which needed to be resolved.

* Moved zfeature support to module/zcommon/zfeature_common.c
* Moved ratelimiting to to module/zfs/zfs_ratelimit.c
* Moved get_system_hostid() to lib/libspl/gethostid.c
* Removed use of cmn_err() in zcommon source
* Removed dprintf_setup() call from zpool_main.c and zfs_main.c
* Removed highbit() and lowbit()
* Removed unnecessary library dependencies from Makefiles
* Removed fletcher-4 kstat in user space
* Added sha2 support explicitly to libzfs
* Added highbit64() and lowbit64() to zpool_util.c

Brian Behlendorf 9631681b75 Fix dnode allocation race
When performing concurrent object allocations using the new
multi-threaded allocator and large dnodes it's possible to
allocate overlapping large dnodes.

This case should have been handled by detecting an error
returned by dnode_hold_impl().  But that logic only checked
the returned dnp was not-NULL, and the dnp variable was not
reset to NULL when retrying.  Resolve this issue by properly
checking the return value of dnode_hold_impl().

Additionally, it was possible that dnode_hold_impl() would
misreport a dnode as free when it was in fact in use.  This
could occurs for two reasons:

* The per-slot zrl_lock must be held over the entire critical
  section which includes the alloc/free until the new dnode
  is assigned to children_dnodes.  Additionally, all of the
  zrl_lock's in the range must be held to protect moving
  dnodes.

* The dn->dn_ot_type cannot be solely relied upon to check
  the type.  When allocating a new dnode its type will be
  DMU_OT_NONE after dnode_create().  Only latter when
  dnode_allocate() is called will it transition to the new
  type.  This means there's a window when allocating where
  it can mistaken for a free dnode.

Update many return and assignment statements to follow the convention
of using the SET_ERROR macro when returning a hard-coded non-zero
value from a function. This aids debugging by recording the error
codes in the debug log.

Tony Hutter 6710381680 Only record zio->io_delay on reads and writes
While investigating https://github.com/zfsonlinux/zfs/issues/6425 I
noticed that ioctl ZIOs were not setting zio->io_delay correctly.  They
would set the start time in zio_vdev_io_start(), but never set the end
time in zio_vdev_io_done(), since ioctls skip it and go straight to
zio_done().  This was causing spurious "delayed IO" events to appear,
which would eventually get rate-limited and displayed as
"Missed events" messages in zed.

To get around the problem, this patch only sets zio->io_delay for read
and write ZIOs, since that's all we care about anyway.

At import time spa_import() calls zvol_create_minors() directly: with
the current implementation we have no way to avoid device node
creation when volmode=none.

Fix this by enforcing volmode=none directly in zvol_alloc().

Ned Bass 8740cf4a2f Add line info and SET_ERROR() to ZFS debug log
Redefine the SET_ERROR macro in terms of __dprintf() so the error
return codes get logged as both tracepoint events (if tracepoints are
enabled) and as ZFS debug log entries.  This also allows us to use
the same definition of SET_ERROR() in kernel and user space.

Define a new debug flag ZFS_DEBUG_SET_ERROR=512 that may be bitwise
or'd into zfs_flags. Setting this flag enables both dprintf() and
SET_ERROR() messages in the debug log. That is, setting
ZFS_DEBUG_SET_ERROR and ZFS_DEBUG_DPRINTF|ZFS_DEBUG_SET_ERROR are
equivalent (this was done for sake of simplicity). Leaving
ZFS_DEBUG_SET_ERROR unset suppresses the SET_ERROR() messages which
helps avoid cluttering up the logs.

To enable SET_ERROR() logging, run:

  echo 1 >   /sys/module/zfs/parameters/zfs_dbgmsg_enable
  echo 512 > /sys/module/zfs/parameters/zfs_flags

Remove the zfs_set_error_class tracepoints event class since
SET_ERROR() now uses __dprintf(). This sacrifices a bit of
granularity when selecting individual tracepoint events to enable but
it makes the code simpler.

Include file, function, and line number information in debug log
entries.  The information is now added to the message buffer in
__dprintf() and as a result the zfs_dprintf_class tracepoints event
class was changed from a 4 parameter interface to a single parameter.

Ned Bass 73aac4aa41 Some additional send stream validity checking
Check in the DMU whether an object record in a send stream being
received contains an unsupported dnode slot count, and return an
error if it does. Failure to catch an unsupported dnode slot count
would result in a panic when the SPA attempts to increment the
reference count for the large_dnode feature and the pool has the
feature disabled. This is not normally an issue for a well-formed
send stream which would have the DMU_BACKUP_FEATURE_LARGE_DNODE flag
set if it contains large dnodes, so it will be rejected as
unsupported if the required feature is disabled. This change adds a
missing object record field validation.

Add missing stream feature flag checks in
dmu_recv_resume_begin_check().

Consolidate repetitive comment blocks in dmu_recv_begin_check().

Update zstreamdump to print the dnode slot count (dn_slots) for an
object record when running in verbose mode.

Brian Behlendorf 3f759c0c73 Fix 'zpool clear' on suspended pools
'zpool clear' should be able to resume I/O on suspended, but otherwise
healthy, pools.

4a283c7 accidentally introduced a new code path where we call
txg_wait_synced() on the suspended pool before we had the chance to
resume I/O via zio_resume(): this results in the 'zpool clear'
command hanging indefinitely, waiting for a TXG that cannot be synced.

Fix this by avoiding the call to txg_wait_synced().

Justin Bedő f269060a24 Fix autoconf detection of super_setup_bdi_name
The previous autoconf test for the presence of super_setup_bdi_name()
uses an invocation with an incorrect type signature, producing a
warning by the compiler when the test is run. This gets elevated to an
error when compiling with -Werror=format-security, causing autoconf to
falsely infer super_setup_bdi_name() is not present. This updates the
testing code to match the invocation used in
include/linux/vfs_compat.h.
