MFOpenZFS: ZVOLs should not be allowed to have children
zfs create, receive and rename can bypass this hierarchy rule. Update both userland and kernel module to prevent this issue and use pyzfs unit tests to exercise the ioctls directly.
Note: this commit slightly changes zfs_ioc_create() ABI. This allow to differentiate a generic error (EINVAL) from the specific case where we tried to create a dataset below a ZVOL (ZFS_ERR_WRONG_PARENT).

MFC r337567 (by mmacy): Performance optimization of AVL tree comparator functions
MFV: commit ee36c709c3d5f7040e1bd11f5c75318aa03e789f Author: Gvozden Neskovic <neskovic@gmail.com> Date: Sat Aug 27 20:12:53 2016 +0200
perf: 2.75x faster ddt_entry_compare() First 256bits of ddt_key_t is a block checksum, which are expected to be close to random data. Hence, on average, comparison only needs to look at first few bytes of the keys. To reduce number of conditional jump instructions, the result is computed as: sign(memcmp(k1, k2)).
Sign of an integer 'a' can be obtained as: `(0 < a) - (a < 0)` := {-1, 0, 1} , which is computed efficiently. Synthetic performance evaluation of original and new algorithm over 1G random keys on 2.6GHz Intel(R) Xeon(R) CPU E5-2660 v3:

https://www.illumos.org/issues/8056 The send size estimate for a zvol can be too low, if the size of the record headers (dmu_replay_record_t's) is a significant portion of the size. This is typically the case when the data is highly compressible, especially with embedded blocks. The problem is that dmu_adjust_send_estimate_for_indirects() assumes that blocks are the size of the "recordsize" property (128KB). However, for zvols, the blocks are the size of the "volblocksize" property (8KB). Therefore, we estimate that there will be 16x less record headers than there really will be.

illumos/illumos-gate@770499e185d15678ccb0be57ebc626ad18d93383 https://github.com/illumos/illumos-gate/commit/770499e185d15678ccb0be57ebc626ad1 8d93383
https://www.illumos.org/issues/8021 The ARC buf data project (known simply as "ABD" since its genesis in the ZoL community) changes the way the ARC allocates `b_pdata` memory from using linea r `void *` buffers to using scatter/gather lists of fixed-size 1KB chunks. This improves ZFS's performance by helping to defragment the address space occupied by the ARC, in particular for cases where compressed ARC is enabled. It could also ease future work to allocate pages directly from `segkpm` for minimal- overhead memory allocations, bypassing the `kmem` subsystem. This is essentially the same change as the one which recently landed in ZFS on Linux, although they made some platform-specific changes while adapting this work to their codebase: 1. Implemented the equivalent of the `segkpm` suggestion for future work mentioned above to bypass issues that they've had with the Linux kernel memory allocator. 2. Changed the internal representation of the ABD's scatter/gather list so it could be used to pass I/O directly into Linux block device drivers. (This feature is not available in the illumos block device interface yet.)
FreeBSD notes: - the actual (default) chunk size is 4KB (despite the text above saying 1KB) - we can try to reimplement ABDs, so that they are not permanently mapped into the KVA unless explicitly requested, especially on platforms with scarce KVA - we can try to use unmapped I/O and avoid intermediate allocation of a linear, virtual memory mapped buffer - we can try to avoid extra data copying by referring to chunks / pages in the original ABD

This resolves two 'zfs recv' issues. First, when receiving into an existing filesystem, a snapshot created during the receive process is not added to the guid->dataset map for the stream, resulting in failed lookups for deduped streams when a WRITE_BYREF record refers to a snapshot received earlier in the stream. Second, the newly created snapshot was also not set properly, referencing the snapshot before the new receiving dataset rather than the existing filesystem.

The uncompressed data should be short-lived allowing the ARC to cache a much larger amount of data.

This allows to do a full (non-incremental send) and receive it as a clone of an existing dataset. It can leverage nopwrite to share blocks with the origin. This can be used to change the relationship of datasets on the target. For example, maybe on the source you have:
A ---- B ---- C
And you have sent to the target a full of B, and the incremental B->C:
B ---- C
You later realize that you want to have A on the target. You will have to do a full send of A, but nopwrite can save you space on the target if you receive it as a clone of B, assuming that A and B have some blocks inxi common:
B ---- C \ A

In r286705 (Illumos 5960/a2cdcdd), a separate thread is created with curproc as parent. In the case of a send or receive, the curproc would be the userland application that issues the ioctl. This would trigger an assertion failure introduced in Solaris compatibility shims in r196458 when kernel is compiled with INVARIANTS.
Fix this by using p0 (proc0 or kernel) as the parent thread when creating the kernel threads.

MFV r275783:
Convert ARC flags to use enum. Previously, public flags are defined in arc.h and private flags are defined in arc.c which can lead to confusion and programming errors.
Consistently use 'hdr' (when referencing arc_buf_hdr_t) instead of 'buf' or 'ab' because arc_buf_t are often named 'buf' as well.
Illumos issue: 5369 arc flags should be an enum 5370 consistent arc_buf_hdr_t naming scheme

Remove "dbuf phys" db->db_data pointer aliases.
Use function accessors that cast db->db_data to the appropriate "phys" type, removing the need for clients of the dmu buf user API to keep properly typed pointer aliases to db->db_data in order to conveniently access their data.

MFV r268455:
Use reserved space for ZFS administrative commands.
We reserve 1/2^spa_slop_shift = 1/32 or 3.125% of pool space (or 32MB at least) for system use. Most ZPL operations, e.g. write(2), creat(2), will fail with ENOSPC if we fall below this.
Certain operations, e.g. file removal and most administrative actions, still permitted until half of the slop space is used. This would allow users to use these operations to free up space in the pool when pool is close to full but half of slop space is still free.
A very restricted set of operations that frees up space or change quota are always permitted, regardless of the amount of free space.

To quote Illumos issue #3888:
When 'zfs recv -F' is used with an incremental recv it rolls back any changes made since the last snapshot in case new changes were made to the file system while the recv is in progress (without -F the recv would fail when it does it's final check to commit the recv-ed data as the recv-ed data conflicts with the newly written data).
However, if there is a snapshot taken after the recv began rolling back to the 'latest' snapshot will not help and the recv will still fail. 'zfs recv -F' should be extended to destroy any snapshots created since the source snapshot when finishing the recv (effectively rolling back through all snapshots, instead of just to the latest snapshot).

Because z_os is NULL, any thread that had already picked up the zfsvfs_t and was sitting in ZFS_ENTER() when we dropped our locks in zfs_resume_fs() will now acquire the lock, attempt to use z_os, and panic.

Merge libzfs_core branch: includes MFV 238590, 238592, 247580
MFV 238590, 238592: In the first zfs ioctl restructuring phase, the libzfs_core library was introduced. It is a new thin library that wraps around kernel ioctl's. The idea is to provide a forward-compatible way of dealing with new features. Arguments are passed in nvlists and not random zfs_cmd fields, new-style ioctls are logged to pool history using a new method of history logging.
http://blog.delphix.com/matt/2012/01/17/the-future-of-libzfs/
MFV 247580 [1]: To address issues of several deadlocks and race conditions the locking code around dsl_dataset was rewritten and the interface to synctasks was changed.
User-Visible Changes: "zfs snapshot" can create more arbitrary snapshots at once (atomically) "zfs destroy" destroys multiple snapshots at once "zfs recv" has improved performance
Backward Compatibility: I have extended the compatibility layer to support full backward compatibility by remapping or rewriting the responsible ioctl arguments. Old utilities are fully supported by the new kernel module.
Forward Compatibility: New utilities work with old kernels with the following restrictions: - creating, destroying, holding and releasing of multiple snapshots at once is not supported, this includes recursive (-r) commands
Illumos ZFS issues: 2882 implement libzfs_core 2900 "zfs snapshot" should be able to create multiple, arbitrary snapshots at once 3464 zfs synctask code needs restructuring

Re-apply onnv-gate revisions 7994 and 8986 (corresponds to FreeBSD revision 200726 and 200727). It looks like that the two revisions were not applied in the right sequence, I found this when comparing with the OpenSolaris code.

Update ZFS from version 6 to 13 and bring some FreeBSD-specific changes.
This bring huge amount of changes, I'll enumerate only user-visible changes:
- Delegated Administration
Allows regular users to perform ZFS operations, like file system creation, snapshot creation, etc.
- L2ARC
Level 2 cache for ZFS - allows to use additional disks for cache. Huge performance improvements mostly for random read of mostly static content.
- slog
Allow to use additional disks for ZFS Intent Log to speed up operations like fsync(2).
- vfs.zfs.super_owner
Allows regular users to perform privileged operations on files stored on ZFS file systems owned by him. Very careful with this one.
- chflags(2)
Not all the flags are supported. This still needs work.
- ZFSBoot
Support to boot off of ZFS pool. Not finished, AFAIK.
Submitted by: dfr
- Snapshot properties
- New failure modes
Before if write requested failed, system paniced. Now one can select from one of three failure modes: - panic - panic on write error - wait - wait for disk to reappear - continue - serve read requests if possible, block write requests
- Refquota, refreservation properties
Just quota and reservation properties, but don't count space consumed by children file systems, clones and snapshots.
- Sparse volumes
ZVOLs that don't reserve space in the pool.
- External attributes
Compatible with extattr(2).
- NFSv4-ACLs
Not sure about the status, might not be complete yet.
Submitted by: trasz
- Creation-time properties
- Regression tests for zpool(8) command.
