наб 3a909fe33e libzfs, libzfs_core: send: always write to pipe
By introducing lzc_send_wrapper() and routing all ZFS_IOC_SEND*
users through it, we fix a Linux 5.10-introduced bug (see comment)

This is all /transparent/ to the users API, ABI, and usage-wise,
and disabled on FreeBSD and if the output is already a pipe,
and transparently nestable (i.e. zfs_send_one() is wrapped,
but so is lzc_send_redacted() it calls to ‒ this wouldn't be strictly
necessary if ZFS_IOC_SEND_PROGRESS wasn't strictly denominational w.r.t.
the descriptor the send is happening on)

Fix ENOSPC when unlinking multiple files from full pool
When unlinking multiple files from a pool at 100% capacity, it was
possible for ENOSPC to be returned after the first unlink.  e.g.

    rm -f /mnt/fs/test1.0.0 /mnt/fs/test1.1.0 /mnt/fs/test1.2.0
    rm: cannot remove '/mnt/fs/test1.1.0': No space left on device
    rm: cannot remove '/mnt/fs/test1.2.0': No space left on device

After waiting for the pending deferred frees from the first unlink to
be processed the remaining files can then be unlinked.  This is caused
by the quota limit in dsl_dir_tempreserve_impl() being temporarily
decreased to the allocatable pool capacity less any deferred free
space.

This is resolved using the existing mechanism of returning ERESTART
when over quota as long as we know enough space will shortly be
available after processing the pending deferred frees.

Umer Saleem 39a4daf742
Expose additional file level attributes
ZFS allows to update and retrieve additional file level attributes for
FreeBSD. This commit allows additional file level attributes to be
updated and retrieved for Linux. These include the flags stored in the
upper half of z_pflags only.

Two new IOCTLs have been added for this purpose. ZFS_IOC_GETDOSFLAGS
can be used to retrieve the attributes, while ZFS_IOC_SETDOSFLAGS can
be used to update the attributes.

Attributes that are allowed to be updated include ZFS_IMMUTABLE,
ZFS_APPENDONLY, ZFS_NOUNLINK, ZFS_ARCHIVE, ZFS_NODUMP, ZFS_SYSTEM,
ZFS_HIDDEN, ZFS_READONLY, ZFS_REPARSE, ZFS_OFFLINE and ZFS_SPARSE.
Flags can be or'd together while calling ZFS_IOC_SETDOSFLAGS.

Handle aarch64 defines seperate from arm
aarch64 is a different architecture than arm. Some
compilers might choke when both __arm__ and __aarch64__
are defined.

This change separates the checks for arm and for
aarch64 in the isa_defs.h header files.

Use _Noreturn (C11; GNU89) properly
A function that returns with no value is a different thing from a
function that doesn't return at all.  Those are two orthogonal
concepts, commonly confused.

pthread_create(3) expects a pointer to a start routine that has a
very precise prototype:

    void *(*start_routine)(void *);

However, other thread functions, such as kernel ones, expect:

    void (*start_routine)(void *);

Providing a different one is incorrect, and has only been working
because the ABIs happen to produce a compatible function.

We should use '_Noreturn void', since it's the natural type, and
then provide a '_Noreturn void *' wrapper for pthread functions.

For consistency, replace most cases of __NORETURN or
__attribute__((noreturn)) by _Noreturn.  _Noreturn is understood
by -std=gnu89, so it should be safe to use everywhere.

log xattr=sa create/remove/update to ZIL
As such, there are no specific synchronous semantics defined for
the xattrs. But for xattr=on, it does log to ZIL and zil_commit() is
done, if sync=always is set on dataset. This provides sync semantics
for xattr=on with sync=always set on dataset.

For the xattr=sa implementation, it doesn't log to ZIL, so, even with
sync=always, xattrs are not guaranteed to be synced before xattr call
returns to caller. So, xattr can be lost if system crash happens, before
txg carrying xattr transaction is synced.

This change adds xattr=sa logging to ZIL on xattr create/remove/update
and xattrs are synced to ZIL (zil_commit() done) for sync=always.
This makes xattr=sa behavior similar to xattr=on.

Implementation notes:
The actual logging is fairly straight-forward and does not warrant
additional explanation.
However, it has been 14 years since we last added new TX types
to the ZIL [1], hence this is the first time we do it after the
introduction of zpool features. Therefore, here is an overview of the
feature activation and deactivation workflow:

1. The feature must be enabled. Otherwise, we don't log the new
    record type. This ensures compatibility with older software.
2. The feature is activated per-dataset, since the ZIL is per-dataset.
3. If the feature is enabled and dataset is not for zvol, any append to
    the ZIL chain will activate the feature for the dataset. Likewise
    for starting a new ZIL chain.
4. A dataset that doesn't have a ZIL chain has the feature deactivated.

We ensure (3) by activating on the first zil_commit() after the feature
was enabled. Since activating the features requires waiting for txg
sync, the first zil_commit() after enabling the feature will be slower
than usual. The downside is that this is really a conservative
approximation: even if we never append a 'TX_SETSAXATTR' to the ZIL
chain, we pay the penalty for feature activation. The upside is that the
user is in control of when we pay the penalty, i.e., upon enabling the
feature.

We ensure (4) by hooking into zil_sync(), where ZIL destroy actually
happens.

One more piece on feature activation, since it's spread across
multiple functions:

zil_commit()
  zil_process_commit_list()
    if lwb == NULL // first zil_commit since zil_open
      zil_create()
        if no log block pointer in ZIL header:
          if feature enabled and not active:
	    // CASE 1
            enable, COALESCE txg wait with dmu_tx that allocated the
	    log block
         else // log block was allocated earlier than this zil_open
          if feature enabled and not active:
	    // CASE 2
            enable, EXPLICIT txg wait
    else // already have an in-DRAM LWB
      if feature enabled and not active:
        // this happens when we enable the feature after zil_create
	// CASE 3
        enable, EXPLICIT txg wait

Cross-platform xattr user namespace compatibility
ZFS on Linux originally implemented xattr namespaces in a way that is
incompatible with other operating systems.  On illumos, xattrs do not
have namespaces.  Every xattr name is visible.  FreeBSD has two
universally defined namespaces: EXTATTR_NAMESPACE_USER and
EXTATTR_NAMESPACE_SYSTEM.  The system namespace is used for protected
FreeBSD-specific attributes such as MAC labels and pnfs state.  These
attributes have the namespace string "freebsd:system:" prefixed to the
name in the encoding scheme used by ZFS.  The user namespace is used
for general purpose user attributes and obeys normal access control
mechanisms.  These attributes have no namespace string prefixed, so
xattrs written on illumos are accessible in the user namespace on
FreeBSD, and xattrs written to the user namespace on FreeBSD are
accessible by the same name on illumos.

Linux has several xattr namespaces.  On Linux, ZFS encodes the
namespace in the xattr name for every namespace, including the user
namespace.  As a consequence, an xattr in the user namespace with the
name "foo" is stored by ZFS with the name "user.foo" and therefore
appears on FreeBSD and illumos to have the name "user.foo" rather than
"foo".  Conversely, none of the xattrs written on FreeBSD or illumos
are accessible on Linux unless the name happens to be prefixed with one
of the Linux xattr namespaces, in which case the namespace is stripped
from the name.  This makes xattrs entirely incompatible between Linux
and other platforms.

We want to make the encoding of user namespace xattrs compatible across
platforms.  A critical requirement of this compatibility is for xattrs
from existing pools from FreeBSD and illumos to be accessible by the
same names in the user namespace on Linux.  It is also necessary that
existing pools with xattrs written by Linux retain access to those
xattrs by the same names on Linux.  Making user namespace xattrs from
Linux accessible by the correct names on other platforms is important.
The handling of other namespaces is not required to be consistent.

Add a fallback mechanism for listing and getting xattrs to treat xattrs
as being in the user namespace if they do not match a known prefix.

Do not allow setting or getting xattrs with a name that is prefixed
with one of the namespace names used by ZFS on supported platforms.

Allow choosing between legacy illumos and FreeBSD compatibility and
legacy Linux compatibility with a new tunable.  This facilitates
replication and migration of pools between hosts with different
compatibility needs.

The tunable controls whether or not to prefix the namespace to the
name.  If the xattr is already present with the alternate prefix,
remove it so only the new version persists.  By default the platform's
existing convention is used.

Linux 5.16 compat: don't use XSTATE_XSAVE to save FPU state
Linux 5.16 moved XSTATE_XSAVE and XSTATE_XRESTORE out of our reach,
so add our own XSAVE{,OPT,S} code and use it for Linux 5.16.

Please note that this differs from previous behavior in that it
won't handle exceptions created by XSAVE an XRSTOR. This is sensible
for three reasons.

 - Exceptions during XSAVE and XRSTOR can only occur if the feature
   is not supported or enabled or the memory operand isn't aligned
   on a 64 byte boundary. If this happens something else went
   terribly wrong, and it may be better to stop execution.

 - Previously we just printed a warning and didn't handle the fault,
   this is arguable for the above reason.

 - All other *SAVE instruction also don't handle exceptions, so this
   at least aligns behavior.

Finally add a test to catch such a regression in the future.

zvol: make calls to platform ops static
There's no need to make the platform ops dynamic dispatch.

This change replaces the dynamic dispatch with static calls to the
platform-specific functions.
To avoid name collisions, prefix all platform-specific functions
with `zvol_os_`.
I actually find `zvol_..._os` slightly nicer to read in the calling
code, but having it as a prefix is useful.

Advantage:
- easier jump-to-definition / grepping
- potential benefits to static analysis
- better legibility

spl: Don't check FreeBSD rwlocks for double initialization (#13019)
This checking breaks KMSAN since it effectively loads from uninitialized
memory to see if the lock is already initialized.  This happens in
dnode_cons() for example.  This checking is not very useful, partly due
to UMA's memory trashing, and is already disabled for mutexes.  Make
mutexes and rwlocks consistent: remove double-initialization checking
for rwlocks, and pass SX_NEW to disable the same checking in
lock_init().

No functional change intended, this affects only debug builds.

As a side note, kmem cache constructors/destructors are implemented
suboptimally on FreeBSD.  FreeBSD's slab allocator, UMA, supports two
pairs of constructors/destructors: ctor/dtor and init/fini.  The former
are called upon every allocation and free of an item, while the latter
are called when an item is imported or released from a zone,
respectively.  That is, when a slab is allocated to a particular cache,
it is subdivided into items, and init is called on each.  fini is called
when the slab is being prepared to be freed back to the system.  The
intent is for them to initialize static fields such as locks, which
do not need to be initialized upon each allocation of an item.

In illumos, kmem_cache constructors/destructors correspond to UMA's
init/fini callbacks.  However, in the SPL they are implemented as UMA
ctor/dtors, meaning that they get called far more often than necessary.
This may be difficult to fix, since new code may assume the kmem cache
ctor/dtors are in fact called upon each allocation/free, and there
doesn't seem to be a clear way to implement the intended semantics on
Linux.

Avoid memory allocations in the ARC eviction thread
When the eviction thread goes to shrink an ARC state, it allocates a set
of marker buffers used to hold its place in the state's sublists.

This can be problematic in low memory conditions, since
1) the allocation can be substantial, as we allocate NCPU markers;
2) on at least FreeBSD, page reclamation can block in
   arc_wait_for_eviction()

In particular, in stress tests it's possible to hit a deadlock on
FreeBSD when the number of free pages is very low, wherein the system is
waiting for the page daemon to reclaim memory, the page daemon is
waiting for the ARC eviction thread to finish, and the ARC eviction
thread is blocked waiting for more memory.

Try to reduce the likelihood of such deadlocks by pre-allocating markers
for the eviction thread at ARC initialization time.  When evicting
buffers from an ARC state, check to see if the current thread is the ARC
eviction thread, and use the pre-allocated markers for that purpose
rather than dynamically allocating them.

Verify dRAID empty sectors
Verify that all empty sectors are zero filled before using them to
calculate parity.  Failure to do so can result in incorrect parity
columns being generated and written to disk if the contents of an
empty sector are non-zero.  This was possible because the checksum
only protects the data portions of the buffer, not the empty sector
padding.

This issue has been addressed by updating raidz_parity_verify() to
check that all dRAID empty sectors are zero filled.  Any sectors
which are non-zero will be fixed, repair IO issued, and a checksum
error logged.  They can then be safely used to verify the parity.

This specific type of damage is unlikely to occur since it requires
a disk to have silently returned bad data, for an empty sector, while
performing a scrub.  However, if a pool were to have been damaged
in this way, scrubbing the pool with this change applied will repair
both the empty sector and parity columns as long as the data checksum
is valid.  Checksum errors will be reported in the `zpool status`
output for any repairs which are made.

zcommon: pre-iterate over sysfs instead of statting every feature
If sufficient memory (<2K, realistically) is available, libzfs_init()
can be significantly shorted by iterating over the correct sysfs
directory before registrations, we can turn 168 stats into 15/18
syscalls (3 opens (6 if built in), 3 fstats, 6 getdentses, and 3
closes), a tenfoldish reduction; this is probably a bit faster, too.

The list is always optional, and registration functions (and one-off
users) can simply pass NULL, which will fall back to the previous
mechanism

Also, don't allocate in zfs_mod_supported_impl, and use use access()
instead of stat(), since existence is really what we care about

Also, fix pre-prop-checking compat in fallback for built-in ZFS

If the fields to be listed and sorted by are constrained
to those populated by dsl_dataset_fast_stat(), then
zfs list is much faster, as it does not need to open each

A previous optimization by Pawel Dawidek

of this to make listing snapshot names sorted only by name
much faster.

However, it was limited to `-o name -s name`, this work
extends this optimization to work with:
  - name
  - guid
  - createtxg
  - numclones
  - inconsistent
  - redacted
  - origin
and could be further extended to any other properties
supported by dsl_dataset_fast_stat() or similar, that do
not require extra locking or reading from disk.

To handle this zfs_holey_common() was updated to asynchronously

Additionally, while not strictly required, the dn_struct_rwlock is
now held over the dirty check to prevent the dnode structure from
changing.  This ensures that a clean dnode can't be dirtied before
the data/hole is located.  The range lock is now also taken to
ensure the call cannot race with zfs_write().

Furthermore, the code was refactored to provide a dnode_is_dirty()
helper function which checks the dnode for any dirty records to
determine its dirtiness.

Simplify and document OpenZFS library dependencies
For those not already familiar with the code base it can be a
challenge to understand how the libraries are laid out.  This
has sometimes resulted in functionality being added in the
wrong place.  To help avoid that in the future this commit
documents the high-level dependencies for easy reference in
lib/Makefile.am.  It also simplifies a few things.

- Switched libzpool dependency on libzfs_core to libzutil.
  This change makes it clear libzpool should never depend
  on the ioctl() functionality provided by libzfs_core.

- Moved zfs_ioctl_fd() from libzutil to libzfs_core and
  renamed it lzc_ioctl_fd().  Normal access to the kmods
  should all be funneled through the libzfs_core library.
  The sole exception is the pool_active() which was updated
  to not use lzc_ioctl_fd() to remove the libzfs_core
  dependency.

- Removed libzfs_core dependency on libzutil.

- Removed the lib/libzfs/os/freebsd/libzfs_ioctl_compat.c
  source file which was all dead code.

- Removed libzfs_core dependency from mkbusy and ctime
  test utilities.  It was only needed for some trivial
  wrapper functions and that code is easy to replicate
  to shed the unneeded dependency.

Use fallthrough macro
As of the Linux 5.9 kernel a fallthrough macro has been added which
should be used to anotate all intentional fallthrough paths.  Once
all of the kernel code paths have been updated to use fallthrough
the -Wimplicit-fallthrough option will because the default.  To
avoid warnings in the OpenZFS code base when this happens apply
the fallthrough macro.

Linux 5.15 compat: block device readahead
The 5.15 kernel moved the backing_dev_info structure out of
the request queue structure which causes a build failure.

Rather than look in the new location for the BDI we instead
detect this upstream refactoring by the existance of either
the blk_queue_update_readahead() or disk_update_readahead()
functions.  In either case, there's no longer any reason to
manually set the ra_pages value since it will be overridden
with a reasonable default (2x the block size) when
blk_queue_io_opt() is called.

Therefore, we update the compatibility wrapper to do nothing
for 5.9 and newer kernels.  While it's tempting to do the
same for older kernels we want to keep the compatibility
code to preserve the existing behavior.  Removing it would
effectively increase the default readahead to 128k.

Richard Yao abbf0bd4eb Linux 4.11 compat: statx support
Linux 4.11 added a new statx system call that allows us to expose crtime
as btime. We do this by caching crtime in the znode to match how atime,
ctime and mtime are cached in the inode.

statx also introduced a new way of reporting whether the immutable,
append and nodump bits have been set. It adds support for reporting
compression and encryption, but the semantics on other filesystems is
not just to report compression/encryption, but to allow it to be turned
on/off at the file level. We do not support that.

We could implement semantics where we refuse to allow user modification
of the bit, but we would need to do a dnode_hold() in zfs_znode_alloc()
to find out encryption/compression information. That would introduce
locking that will have a minor (although unmeasured) performance cost.
It also would be inferior to zdb, which reports far more detailed
information. We therefore omit reporting of encryption/compression
through statx in favor of recommending that users interested in such
information use zdb.

Remove b_pabd/b_rabd allocation from arc_hdr_alloc()
When a header is allocated for full overwrite it is a waste of time
to allocate b_pabd/b_rabd for it, since arc_write() will free them
without ever being touched.  If it is a read or a partial overwrite
then arc_read() and arc_hdr_decrypt() allocate them explicitly.

Reduced memory allocation in user threads also reduces ARC eviction
throttling there, proportionally increasing it in ZIO threads, that
is not good.  To minimize or even avoid it introduce ARC allocation
reserve, allowing certain arc_get_data_abd() callers to allocate a
bit longer in situations where user threads will already throttle.

Nowadays 8KB does not allow adequate compression or even decent space

especially on RAIDZ and DRAID.  It effectively limits write throughput
to only 2-3GB/s (250-350K blocks/s) due to sync thread, allocation,
vdev queue and other block rate bottlenecks.  It keeps L2ARC expensive
despite many optimizations and dedup just unrealistic.

Optimize allocation throttling
Remove mc_lock use from metaslab_class_throttle_*().  The math there
is based on refcounts and so atomic, so the only race possible there
is between zfs_refcount_count() and zfs_refcount_add().  But in most
cases metaslab_class_throttle_reserve() is called with the allocator
lock held, which covers the race.  In cases where the lock is not
held, GANG_ALLOCATION() or METASLAB_MUST_RESERVE are set, and so we
do not use zfs_refcount_count().  And even if we assume some other
non-existing scenario, the worst that may happen from this race is
few more I/Os get to allocation earlier, that is not a problem.

Move locks and data of different allocators into different cache
lines to avoid false sharing.  Group spa_alloc_* arrays together
into single array of aligned struct spa_alloc spa_allocs.  Align
struct metaslab_class_allocator.
