Richard Laager 4fc411f7a3 initramfs: Set elevator=noop on the rpool's disks
ZFS already sets elevator=noop for wholedisk vdevs (for all pools), but
typical root-on-ZFS installations use partitions.  This sets
elevator=noop on the disks in the root pool.

Ubuntu 16.04 and 16.10 had this.  It was lost in 17.04 due to Debian
switching to this upstream initramfs script.

Jason King f3c8c9e6f0 OpenZFS 640 - number_to_scaled_string is duplicated in several commands
Porting Notes:
- The OpenZFS patch added nicenum_scale() and nicenum() to a
  library not used by ZFS.  Rather than pull in a new dependency
  the version of nicenum in lib/libzpool/util.c was simply
  replaced with the new one.

usr/src/cmd/zdb/zdb_il.c

	Fix numerous warnings, including:

	* shadowing global definitions
	* signed vs unsigned comparisons
	* missing prototypes, or missing static declarations
	* unused variables and functions
	* Unreadable array initializations

Porting Notes:

  consistency the OpenZFS version of a change was applied if the
  warning was addressed in an equivalent but different fashion.

* `zpool reopen` without arguments,
* `zpool reopen` with pool name as argument,
* `zpool reopen` while scrubbing,
* `zpool reopen -n` while scrubbing,
* `zpool reopen -n` while resilvering,

Brian Behlendorf bbf1ad67cd Remove vn_rename and vn_remove dependency
The only place vn_rename and vn_remove are used is when writing
out an updated pool configuration file.  By truncating the file
instead of renaming and removing it we can avoid having to implement
these interfaces entirely.  Functionally an empty cache file is
treated the same as a missing cache file.  This is particularly
advantageous because the Linux kernel has never provided a way
to reliably implement vn_rename and vn_remove.

The cachefile_004_pos.ksh test case was updated to understand
that an empty cache file is the same as a missing one.

The zfs-import-* systemd service files were not updated to use
ConditionFileNotEmpty in place of ConditionPathExists.  This
means that after exporting all pools and rebooting new pools
will not the scanned for on the next boot.  This small change
should not impact normal usage since pools are not exported
as part of a normal shutdown.

Documentation was updated accordingly.

* Allow a 1% variance in coverage between test runs.  This is

Brian Behlendorf e0922b0421 Fixes for SPARC support
The current code base almost compiles on SPARC, but a few fixes are
required for the code to compile (and work efficiently). Code in this 
PR comes from OpenZFS project which was initially dropped when porting
the crypto framework.

Tom Caputi 2637dda8f8 Fix for #6706
This patch resolves an issue where raw sends would fail to send
encryption parameters if the wrapping key was unloaded and reloaded
before the data was sent and the dataset wass not an encryption root.
The code attempted to lookup the values from the wrapping key which
was not being initialized upon reload. This change forces the code to
lookup the correct value from the encryption root's DSL Crypto Key.
Unfortunately, this issue led to the on-disk DSL Crypto Key for some
non-encryption root datasets being left with zeroed out encryption
parameters. However, this should not present a problem since these
values are never looked at and are overrwritten upon changing keys.

This patch also fixes an issue where raw, resumable sends were not
being cleaned up appropriately if an invalid DSL Crypto Key was
received.

Tom Caputi b135b9f11a Fix for #6703
This patch resolves an issue where spa_keystore_change_key_sync_impl()
incorrectly recursed into clone DSL Directories while recursively
rewrapping encryption keys. Clones share keys with their origins, so
this logic was incorrect.

Tom Caputi 440a3eb939 Fixes for #6639
Several issues were uncovered by running stress tests with zfs
encryption and raw sends in particular. The issues and their
associated fixes are as follows:

* arc_read_done() has the ability to chain several requests for
  the same block of data via the arc_callback_t struct. In these
  cases, the ARC would only use the first request's dsobj from
  the bookmark to decrypt the data. This is problematic because
  the first request might be a prefetch zio which is able to
  handle the key not being loaded, while the second might use a
  different key that it is sure will work. The fix here is to
  pass the dsobj with each individual arc_callback_t so that each
  request can attempt to decrypt the data separately.

* DRR_FREE and DRR_FREEOBJECT records in a send file were not
  having their transactions properly tagged as raw during raw
  sends, which caused a panic when the dbuf code attempted to
  decrypt these blocks.

* traverse_prefetch_metadata() did not properly set
  ZIO_FLAG_SPECULATIVE when issuing prefetch IOs.

* Added a few asserts and code cleanups to ensure these issues
  are more detectable in the future.

Tom Caputi 4807c0badb Encryption patch follow-up
* PBKDF2 implementation changed to OpenSSL implementation.

* HKDF implementation moved to its own file and tests
  added to ensure correctness.

* Removed libzfs's now unnecessary dependency on libzpool
  and libicp.

* Ztest can now create and test encrypted datasets. This is
  currently disabled until issue #6526 is resolved, but
  otherwise functions as advertised.

* Several small bug fixes discovered after enabling ztest
  to run on encrypted datasets.

* Fixed coverity defects added by the encryption patch.

* Updated man pages for encrypted send / receive behavior.

* Fixed a bug where encrypted datasets could receive
  DRR_WRITE_EMBEDDED records.

* Minor code cleanups / consolidation.

SPARC optimizations for SHA1Transform()
Passing arguments explicitly into SHA1Transform() increases the number of
registers abailable to the compiler, hence leaving more local and out registers
available. The missing symbol of sha1_consts[], which prevents compiling on
SPARC, is added back, which speeds up the process of utilizing the relative
constants.
This should fix #6738.
