AJ Jordan 5a04b17717 Fix up arcstat(1) to match our version
Turns out the illumos manpage, which is what this originates from, was
written for the original Perl version of the utility which is not the
version in the OpenZFS tree. *That* version originates from a Python
rewrite that was done for FreeNAS. So fix up the manpage to match what
we actually ship (and fix a few typos in the process).

Change zfsunlock for better busybox compatibility
It turns out that there are two versions of Busybox, at least on Ubuntu
18.04.  If you have the busybox-static package installed, you get a
busybox that supports `ps a` and `head`.  If you only have
busybox-initramfs, you don't.  Either way, you have `awk`.

This change should also make this compatible with GNU ps, if you somehow
end up with that in the initramfs environment.

Improvements on persistent L2ARC
Functional changes:

We implement refcounts of log blocks and their aligned size on the
cache device along with two corresponding arcstats. The refcounts are
reflected in the header of the device and provide valuable information
as to whether log blocks are accounted for correctly. These are
dynamically adjusted as log blocks are committed/evicted. zdb also uses
this information in the device header and compares it to the
corresponding values as reported by dump_l2arc_log_blocks() which
emulates l2arc_rebuild(). If the refcounts saved in the device header
report higher values, zdb exits with an error. For this feature to work
correctly there should be no active writes on the device. This is also
employed in the tests of persistent L2ARC. We extend the structure of
the cache device header by adding the two new variables mirroring the
refcounts after the existing variables to preserve backward
compatibility in terms of persistent L2ARC.

1) a new arcstat "l2_log_blk_asize" and refcount "l2ad_lb_asize" which
   reflect the total aligned size of log blocks on the device. This is
   also reflected in the header of the cache device as "dh_lb_asize".
2) a new arcstat "l2arc_log_blk_count" and refcount "l2ad_lb_count"
   which reflect the total number of L2ARC log blocks present on cache
   devices.  It is also reflected in the header of the cache device as
   "dh_lb_count".

In l2arc_rebuild_vdev() if the amount of committed log entries in a log
block is 0 and the device header is valid we update the device header.
This will facilitate trimming of the whole device in this case when
TRIM for L2ARC is implemented.

Improve loop protection in l2arc_rebuild() by using the starting offset
of the payload of each log block instead of the starting offset of the
log block.

If the zio in l2arc_write_buffers() fails, restore the lbps array in the
header of the device to its previous state in l2arc_write_done().

If l2arc_rebuild() ends the rebuild process without restoring any L2ARC
log blocks in ARC and without any other error, this means that the lbps
array in the header is pointing to non-existent or invalid log blocks.
Reset the device header in this case.

In l2arc_rebuild() change the zfs_dbgmsg messages to
spa_history_log_internal() making them user visible with zpool history
command.

Non-functional changes:

Make the first test in persistent L2ARC use `zdb -lll` to increase
coverage in `zdb.c`.

Rename psize with asize when referring to log blocks, since
L2ARC_SET_PSIZE stores the vdev aligned size for log blocks. Also
rename dh_log_blk_entries to dh_log_entries to make it clear that
it is a mirror of l2ad_log_entries. Added comments for both changes.

Fix inaccurate comments for example in l2arc_log_blk_restore().

Add asserts at the end in l2arc_evict() and l2arc_write_buffers().

Add support for boot environment data to be stored in the label
Modern bootloaders leverage data stored in the root filesystem to 
enable some of their powerful features. GRUB specifically has a grubenv 
file which can store large amounts of configuration data that can be 
read and written at boot time and during normal operation. This allows 
sysadmins to configure useful features like automated failover after 
failed boot attempts. Unfortunately, due to the Copy-on-Write nature 
of ZFS, the standard behavior of these tools cannot handle writing to
ZFS files safely at boot time. We need an alternative way to store 
data that allows the bootloader to make changes to the data.

This work is very similar to work that was done on Illumos to enable 
similar functionality in the FreeBSD bootloader. This patch is different 
in that the data being stored is a raw grubenv file; this file can store 
arbitrary variables and values, and the scripting provided by grub is 
powerful enough that special structures are not required to implement 
advanced behavior.

We repurpose the second padding area in each label to store the grubenv 
file, protected by an embedded checksum. We add two ioctls to get and 
set this data, and libzfs_core and libzfs functions to access them more 
easily. There are no direct command line interfaces to these functions; 
these will be added directly to the bootloader utilities.

Update FreeBSD SPL atomics
Sync up with the following changes from FreeBSD:

ZFS: add emulation of atomic_swap_64 and atomic_load_64

Some 32-bit platforms do not provide 64-bit atomic operations that ZFS
requires, either in userland or at all.  We emulate those operations
for those platforms using a mutex.  That is not entirely correct and
it's very efficient.  Besides, the loads are plain loads, so torn
values are possible.

Nevertheless, the emulation seems to work for some definition of work.

This change adds atomic_swap_64, which is already used in ZFS code,
and atomic_load_64 that can be used to prevent torn reads.

FreeBSD-commit: freebsd/freebsd@3458e5d1e6

cleanup of illumos compatibility atomics

atomic_cas_32 is implemented using atomic_fcmpset_32 on all platforms.
Ditto for atomic_cas_64 and atomic_fcmpset_64 on platforms that have
it.  The only exception is sparc64 that provides MD atomic_cas_32 and
atomic_cas_64.
This is slightly inefficient as fcmpset reports whether the operation
updated the target and that information is not needed for cas.
Nevertheless, there is less code to maintain and to add for new
platforms.  Also, the operations are done inline now as opposed to
function calls before.

atomic_add_64_nv is implemented using atomic_fetchadd_64 on platforms
that provide it.

casptr, cas32, atomic_or_8, atomic_or_8_nv are completely removed as
they have no users.

atomic_mtx that is used to emulate 64-bit atomics on platforms that
lack them is defined only on those platforms.

As a result, platform specific opensolaris_atomic.S files have lost
most of their code.  The only exception is i386 where the
compat+contrib code provides 64-bit atomics for userland use.  That
code assumes availability of cmpxchg8b instruction.  FreeBSD does not
have that assumption for i386 userland and does not provide 64-bit
atomics.  Hopefully, this can and will be fixed.

FreeBSD-commit: freebsd/freebsd@e9642c209b

emulate illumos membar_producer with atomic_thread_fence_rel

membar_producer is supposed to be a store-store barrier.
Also, in the code that FreeBSD has ported from illumos membar_producer
is used only with regular stores to regular memory (with respect to
caching).

We do not have an MI primitive for the store-store barrier, so
atomic_thread_fence_rel is the closest we have as it provides
(load | store) -> store barrier.

Previously, membar_producer was an empty function call on all 32-bit
arm-s, 32-bit powerpc, riscv and all mips variants.  I think that it
was inadequate.
On other platforms, such as amd64, arm64, i386, powerpc64, sparc64,
membar_producer was implemented using stronger primitives than required
for a store-store barrier with respect to regular memory access.
For example, it used sfence on amd64 and lock-ed nop in i386 (despite
TSO).
On powerpc64 we now use recommended lwsync instead of eieio.
On sparc64 FreeBSD uses TSO mode.
On arm64/aarch64 we now use dmb sy instead of dmb ish.  Not sure if
this is an improvement, actually.

After this change we can drop opensolaris_atomic.S for aarch64, amd64,
powerpc64 and sparc64 as all required atomic operations have either
direct or light-weight mapping to FreeBSD native atomic operations.

fix up r353340, don't assume that fcmpset has strong semantics

fcmpset can have two kinds of semantics, weak and strong.
For practical purposes, strong semantics means that if fcmpset fails
then the reported current value is always different from the expected
value.  Weak semantics means that the reported current value may be the
same as the expected value even though fcmpset failed.  That's a so
called "sporadic" failure.

I originally implemented atomic_cas expecting strong semantics, but
many platforms actually have weak one.

[PowerPC] [MIPS] Implement 32-bit kernel emulation of atomic64 operations

This is a lock-based emulation of 64-bit atomics for kernel use, split off
from an earlier patch by jhibbits.

This is needed to unblock future improvements that reduce the need for
locking on 64-bit platforms by using atomic updates.

The implementation allows for future integration with userland atomic64,
but as that implies going through sysarch for every use, the current
status quo of userland doing its own locking may be for the best.

Support custom URI schemes for the keylocation property
Every platform has their own preferred methods for implementing URI 
schemes beyond the currently supported file scheme (e.g. 'https' on 
FreeBSD would likely use libfetch, while Linux distros and illumos
would probably use libcurl, etc). It would be helpful if libzfs can 
be extended to support additional schemes in a simple manner.

A table of (scheme, handler_function) pairs is added to libzfs_crypto.c, 
and the existing functions in libzfs_crypto.c so that when the key 
format is ZFS_KEYFORMAT_URI, the scheme from the URI string is 
extracted, and a matching handler it located in the aforementioned 
table (returning an error if no matching handler is found). The handler 
function is then invoked to retrieve the key material (in the format 
specified by the keyformat property) and the key is loaded or the 
handler can return an error to abort the key loading process.

Fix missing ivset guid with resumed raw base recv
This patch corrects a bug introduced in 61152d1069. When
resuming a raw base receive, the dmu_recv code always sets
drc->drc_fromsnapobj to the object ID of the previous
snapshot. For incrementals, this is correct, but for base
sends, this should be left at 0. The presence of this ID
eventually allows a check to run which determines whether
or not the incoming stream and the previous snapshot have
matching IVset guids. This check fails becuase it is not
meant to run when there is no previous snapshot. When it
does fail, the user receives an error stating that the
incoming stream has the problem outlined in errata 4.

This patch corrects this issue by simply ensuring
drc->drc_fromsnapobj is left as 0 for base receives.

Remove deduplicated send/receive code
Deduplicated send streams (i.e. `zfs send -D` and `zfs receive` of such
streams) are deprecated.  Deduplicated send streams can be received by
first converting them to non-deduplicated with the `zstream redup`
command.

This commit removes the code for sending and receiving deduplicated send
streams.  `zfs send -D` will now print a warning, ignore the `-D` flag,
and generate a regular (non-deduplicated) send stream.  `zfs receive` of
a deduplicated send stream will print an error message and fail.

The resulting code simplification (especially in the kernel's support
for receiving dedup streams) should help enable future performance
enhancements.

Several new tests are added which leverage `zstream redup`.

Use a struct to organize metaslab-group-allocator fields
Each metaslab group (of which there is one per top-level vdev) has
several (4, by default) "metaslab group allocators".  Each "allocator"
has its own metaslab that it prefers to allocate from (the "primary"
allocator), and each can perform allocations concurrently with the other
allocators.  In addition to the primary metaslab, there are several
other fields that need to be tracked separately for each allocator.
These are currently stored as several arrays in the metaslab_group_t,
each array indexed by allocator number.

This change organizes all the metaslab-group-allocator-specific fields
into a new struct, metaslab_group_allocator_t.  The metaslab_group_t now
needs only one array indexed by the allocator number - which contains
the metaslab_group_allocator_t's.

Fix zfs send progress reporting
The progress of a send is supposed to be reported by `zfs send -v`, but
it is not.  This works by creating a new user thread (with
pthread_create()) which does ZFS_IOC_SEND_PROGRESS ioctls to check how
much progress has been made.  This IOCTL finds the specified send (since
there may be multiple concurrent sends in the system).  The IOCTL also
checks that the specified send was started by the current process.

On Linux, different threads of the same process are represented as
different `struct task_struct`s (and, confusingly, have different
PID's).  To check if if two threads are in the same process, we need to
check if they have the same `struct task_struct:group_leader`.

We used to to this correctly, but it was inadvertently changed by
30af21b025 (Redacted Send) to simply check if the current
`struct task_struct` is the one that started the send.

This commit changes the code back to checking if the send was started by
a `struct task_struct` with the same `group_leader` as the calling
thread.
