ZTS: zfs_program_json
As of Python 3.5 the default behavior of json.tool was changed to
preserve the input order rather than lexical order.  The test case
expects the output to be sorted so apply the --sort-keys option
to the json.tool command when using Python 3.5 and the option is
supported.

ZTS: devices_001_pos and devices_002_neg
Update the devices_001_pos and devices_002_neg test cases such that the
special block device file created is backed by a ZFS volume.  Specifying
a specific device allows the major and minor numbers to be easily
determined.  Furthermore, this avoids the potentially dangerous behavior
of opening the first block device we happen to find under /dev/.

Steve Mokris d5c97f3de7 Avoid some crashes when importing a pool with corrupt metadata
- Skip invalid DVAs when importing pools in readonly mode
  (in addition to when the config is untrusted).

- Upon encountering a DVA with a null VDEV, fail gracefully
  instead of panicking with a NULL pointer dereference.

If the encryption key is stored in a file, the initramfs should not

Since TTY is the fallback method, this has no effect on systemd

then resuming with the original "printk" state, the user can 
see the password prompt.

Tom Caputi c317c8c811 Allow empty ds_props_obj to be destroyed
Currently, 'zfs list' and 'zfs get' commands can be slow when
working with snapshots that have a ds_props_obj. This is
because the code that discovers all of the properties for these
snapshots needs to read this object for each snapshot, which
almost always ends up causing an extra random synchronous read
for each snapshot. This performance penalty exists even if the
properties on that snapshot have been unset because the object
is normally only freed when the snapshot is freed, even though
it is only created when it is needed.

This patch allows the user to regain 'zfs list' performance on
these snapshots by destroying the ds_props_obj when it no longer
has any entries left. In practice on a production machine, this
optimization seems to make 'zfs list' about 55% faster.

After spa_vdev_remove_aux() is called, the config nvlist is no longer
valid, as it's been replaced by the new one (with the specified device
removed).  Therefore any pointers into the nvlist are no longer valid.
So we can't save the result of
`fnvlist_lookup_string(nv, ZPOOL_CONFIG_PATH)` (in vd_path) across the
call to spa_vdev_remove_aux().

Instead, use spa_strdup() to save a copy of the string before calling
spa_vdev_remove_aux.

Paul Zuchowski f0bf435176 zio_decompress_data always ASSERTs successful decompression
This interferes with zdb_read_block trying all the decompression
algorithms when the 'd' flag is specified, as some are
expected to fail.  Also control the output when guessing
algorithms, try the more common compression types first, allow
specifying lsize/psize, and fix an uninitialized variable.

Fabian-Gruenbichler b119e2c6f1 SIMD: Use alloc_pages_node to force alignment
fxsave and xsave require the target address to be 16-/64-byte aligned.

kmalloc(_node) does not (yet) offer such fine-grained control over
alignment[0,1], even though it does "the right thing" most of the time
for power-of-2 sizes. unfortunately, alignment is completely off when
using certain debugging or hardening features/configs, such as KASAN,
slub_debug=Z or the not-yet-upstream SLAB_CANARY.

Use alloc_pages_node() instead which allows us to allocate page-aligned
memory. Since fpregs_state is padded to a full page anyway, and this
code is only relevant for x86 which has 4k pages, this approach should
not allocate any unnecessary memory but still guarantee the needed
alignment.

John Poduska 7bda69a1a9 ZTS: Fixes for spurious failures of resilver_restart_001 test
The resilver restart test was reported as failing about 2% of the
time. Two issues were found:

- The event log wasn't large enough, so resilver events were missing
- One 'zpool sync' wasn't enough for resilver to start after zinject

both the time waited and requested timeout to the internal log.

Attila Fülöp 3ac34ca375 ICP: Fix out of bounds write
If gcm_mode_encrypt_contiguous_blocks() is called more than once
in succession, with the accumulated lengths being less than
blocksize, ctx->copy_to will be incorrectly advanced. Later, if
out is NULL, the bcopy at line 114 will overflow
ctx->gcm_copy_to since ctx->gcm_remainder_len is larger than the
ctx->gcm_copy_to buffer can hold.

The fix is to set ctx->copy_to only if it's not already set.

For ZoL the issue may be academic, since in all my testing I wasn't
able to hit neither of both conditions needed to trigger it, but
other consumers can easily do so.
