Once per pass through the MMP thread's loop, the vdev tree is walked to
find a suitable leaf to write the next MMP block to. If no such leaf is
found, the thread sleeps for a while and resumes at the top of the loop.
Add an entry to multihost_history when no leaf can be found, and record
the reason in the error column. The error code for such entries is a
bitfield, displayed in hex:
0x1 At least one vdev (interior or leaf) was not writeable.
0x2 At least one writeable leaf vdev was found, but it had a pending
MMP write.
timestamp = the time in seconds since the epoch when no leaf could be
found originally.
duration = the time (in ns) during which no MMP block was written for
this reason. This does not include the preceeding inter-write period
nor the following inter-write period.
vdev_guid = the number of sequential cycles of the MMP thread looop when
this occurred.

b1d21733 made it possible for empty metadnode blocks to be
compressed to a hole, fixing a bug that would cause invalid
metadnode MACs when a send stream attempted to free objects
and allowing the blocks to be reclaimed when they were no
longer needed. However, this patch also introduced a race
condition; if a txg sync occurred after a DRR_OBJECT_RANGE
record was received but before any objects were added, the
metadnode block would be compressed to a hole and lose all
of its encryption parameters. This would cause subsequent
DRR_OBJECT records to fail when they attempted to write
their data into an unencrypted block. This patch defers the
DRR_OBJECT_RANGE handling to receive_object() so that the
encryption parameters are set with each object that is
written into that block.

Provide infrastructure to auto-configure to enum and API changes in the

arc_free_memory has been broken since an API change in Linux v3.14:

2016-07-28 v4.8 75ef7184 mm, vmstat: add infrastructure for per-node

These commits moved some of global_page_state() into
global_node_page_state(). The API change was particularly egregious as,
instead of breaking the old code, it silently did the wrong thing and we
continued using global_page_state() where we should have been using
global_node_page_state(), thus indexing into the wrong array via
NR_SLAB_RECLAIMABLE et al.

2017-09-06 v4.14 c41f012a mm: rename global_page_state to

...and various (incomplete, as it turns out) attempts to accomodate
these changes in ZoL:

Currently, raw zfs sends transfer the encrypted master keys and
objset_phys_t encryption parameters in the DRR_BEGIN payload of
each send file. Both of these are processed as soon as they are
read in dmu_recv_stream(), meaning that the new keys are set
before the new snapshot is received. In addition to the fact that
this changes the user's keys for the dataset earlier than they
might expect, the keys were never reset to what they originally
were in the event that the receive failed. This patch splits the
processing into objset handling and key handling, the later of
which is moved to dmu_recv_end() so that they key change can be

The current design of ZFS encryption only allows a dataset to
have one DSL Crypto Key at a time. As a result, it is important
that the zfs receive code ensures that only one key can be in use
at a time for a given DSL Directory. zfs receive -F complicates
this, since the new dataset is received as a clone of the existing
one so that an atomic switch can be done at the end. To prevent
confusion about which dataset is actually encrypted a check was
added to ensure that encrypted datasets cannot use zfs recv -F to
completely replace existing datasets. Unfortunately, the check did
not take into account unencrypted datasets being overriden by
encrypted ones as a case.
Along the same lines, the code also failed to ensure that raw
recieves could not be done on top of existing unencrypted
datasets, which causes amny problems since the new stream cannot
be decrypted.

Currently, the DMU relies on ZIO layer compression to free LO
dnode blocks that no longer have objects in them. However,
raw receives disable all compression, meaning that these blocks
can never be freed. In addition to the obvious space concerns,
this could also cause incremental raw receives to fail to mount
since the MAC of a hole is different from that of a completely
zeroed block.
This patch corrects this issue by adding a special case in
zio_write_compress() which will attempt to compress these blocks
to a hole even if ZIO_FLAG_RAW_ENCRYPT is set. This patch also
removes the zfs_mdcomp_disable tunable, since tuning it could

This one line patch adds adds a set to os->os_next_write_raw
that was omitted when the code was updated in 1b66810. Without
it, the code (in some instances) could attempt to write raw
encrypted data as regular unencrypted data without the keys
being loaded, triggering an ASSERT in zio_encrypt().

A log_must call was causing count_uberblocks to return more
than just the uberblock count. Remove the log_must since it
was only logging a sleep.

Currently, ZIL claiming dirties objsets which causes
dsl_pool_sync() to attempt to perform user accounting on
them. This causes problems for encrypted datasets that were
raw received before the system went offline since they
cannot perform user accounting until they have their keys
loaded. This triggers an ASSERT in zio_encrypt(). Since
encryption was added, the code now depends on the fact that
data should only be written when objsets are owned. This
patch adds a check in dmu_objset_do_userquota_updates()
to ensure that useraccounting is only done when the objsets
are actually owned for write. As part of this work, the
zfsvfs and zvol code was updated so that it no longer lies
about owning objsets readonly.

This patch corrects a small security issue with 9c5167d1. When the
project dnode was added to the objset_phys_t, it was not included
in the local MAC for cryptographic protection, allowing an attacker
to modify this data without the consent of the key holder. This
patch does represent an on-disk format change for anyone using
project dnodes on an encrypted dataset.
