When a member of a RAIDZ has been replaced with a device smaller than
the original, then the top level vdev can report its expand size as
16.0E.
The reduced child asize causes the RAIDZ to have a vdev_asize lower than
its vdev_max_asize which then results in an underflow during the
calculation of the parents expand size.
Fix this by updating the vdev_asize if it shrinks, which is already
protected by a check against vdev_min_asize so should always be safe.
Also for RAIDZ vdevs, ensure that the sum of their child vdev_min_asize
is always greater than the parents vdev_min_size.

glibc 2.5 compat: use correct header for makedev() et al.
In glibc 2.5, makedev(), major(), and minor() are defined in
sys/sysmacros.h. They are also defined in types.h for backward
compatability, but using these definitions triggers a compile warning.
This breaks the ZFS build, as it builds with -Werror.
autoconf email threads indicate these macros may be defined in
sys/mkdev.h in some cases.
This commit adds configure checks to detect where makedev() is defined:
sys/sysmacros.h
sys/mkdev.h
It assumes major() and minor() are defined in the same place.
The libspl types.h then includes
sys/sysmacros.h (preferred) or
sys/mkdev.h (2nd choice)
if one of those defines makedev().
This is done before including the system types.h.
An alternative would be to remove uses of major, minor, and makedev,
instead comparing the st_dev returned from stat64. These configure
checks would then be unnecessary.
This change revealed that __NORETURN was being defined unnecessarily in
libspl/include/sys/sysmacros.h. That definition is removed.

Linux 4.11 compat: iops.getattr and friends
In torvalds/linux@a528d35, there are changes to the getattr family of functions,
struct kstat, and the interface of inode_operations .getattr.
The inode_operations .getattr and simple_getattr() interface changed to:
int (*getattr) (const struct path *, struct dentry *, struct kstat *,
u32 request_mask, unsigned int query_flags)
The request_mask argument indicates which field(s) the caller intends to use.
Fields the caller has not specified via request_mask may be set in the returned
struct anyway, but their values may be approximate.
The query_flags argument indicates whether the filesystem must update
the attributes from the backing store.
Currently both fields are ignored. It is possible that getattr-related
functions within zfs could be optimized based on the request_mask.
struct kstat includes new fields:
u32 result_mask; /* What fields the user got */
u64 attributes; /* See STATX_ATTR_* flags */
struct timespec btime; /* File creation time */
Fields attribute and btime are cleared; the result_mask reflects this. These
appear to be optional based on simple_getattr() and vfs_getattr() within the
kernel, which take the same approach.

The BLKFLSBUF ioctl is expected to do two things:
- flush dirty pages to stable storage, and
- invalidate clean pages
Unfortunately, the existing implementation of BLKFLSBUF in
zvol_ioctl() only flushes pages which are part of the current
TXG to disk. There may be additional dirty pages in the
page cache which haven't yet been submitted to the DMU and
therefore aren't part of any TXG.
Furthermore because zvol_ioctl() returns 0 the generic
blkdev_flushbuf() does not invalidate the page cache.
Resolve the issue by moving bdev_flush() in to zvol_ioctl()
and explicitly waiting for a full TXG sync. Then invalidate

Fix nfs snapdir automount
The current implementation for allowing nfs to access snapdir is very buggy.
It uses a special fh for snapdirs, such that the next time nfsd does
fh_to_dentry, it actually returns the root inode inside the snapshot. So nfsd
never knows it cross a mountpoint.
The problem is that nfsd will not hold a reference on the vfsmount of the
snapshot. This cause auto unmounter to unmount the snapshot even though nfs is
still holding dentries in it.
To fix this, we return the inode for the snapdirs themselves. However, we also
trigger automount upon fh_to_dentry, and return ESTALE so nfsd will revalidate
and see the mountpoint and do crossmnt.
Because nfsd will now be aware that these are different filesystems users
must add crossmnt to their export options to access snapshot directories.

OpenZFS 7793 - ztest fails assertion in dmu_tx_willuse_space

Background information: This assertion about tx_space_* verifies that we
are not dirtying more stuff than we thought we would. We “need” to know
how much we will dirty so that we can check if we should fail this
transaction with ENOSPC/EDQUOT, in dmu_tx_assign(). While the
transaction is open (i.e. between dmu_tx_assign() and dmu_tx_commit() —
typically less than a millisecond), we call dbuf_dirty() on the exact
blocks that will be modified. Once this happens, the temporary
accounting in tx_space_* is unnecessary, because we know exactly what
blocks are newly dirtied; we call dnode_willuse_space() to track this
more exact accounting.
The fundamental problem causing this bug is that dmu_tx_hold_*() relies
on the current state in the DMU (e.g. dn_nlevels) to predict how much
will be dirtied by this transaction, but this state can change before we
actually perform the transaction (i.e. call dbuf_dirty()).
This bug will be fixed by removing the assertion that the tx_space_*
accounting is perfectly accurate (i.e. we never dirty more than was
predicted by dmu_tx_hold_*()). By removing the requirement that this
accounting be perfectly accurate, we can also vastly simplify it, e.g.
removing most of the logic in dmu_tx_count_*().
The new tx space accounting will be very approximate, and may be more or
less than what is actually dirtied. It will still be used to determine
if this transaction will put us over quota. Transactions that are marked
by dmu_tx_mark_netfree() will be excepted from this check. We won’t make
an attempt to determine how much space will be freed by the transaction
— this was rarely accurate enough to determine if a transaction should
be permitted when we are over quota, which is why dmu_tx_mark_netfree()
was introduced in 2014.
We also won’t attempt to give “credit” when overwriting existing blocks,
if those blocks may be freed. This allows us to remove the
do_free_accounting logic in dbuf_dirty(), and associated routines. This
logic attempted to predict what will be on disk when this txg syncs, to
know if the overwritten block will be freed (i.e. exists, and has no
snapshots).
Porting notes:
- DNODE_SIZE replaced with DNODE_MIN_SIZE in dmu_tx_count_dnode(),
Using the default dnode size would be slightly better.
- DEBUG_DMU_TX wrappers and configure option removed.
- Resolved _by_dnode() conflicts these changes have not yet been
applied to OpenZFS.

Dump unique configurations and Uberblocks in zdb -lu
For zdb -l, detect when the configuration nvlist in some label l (l>0)
is the same as a configuration already dumped. If so, do not dump it.
Make a similar check when dumping Uberblocks for zdb -lu. Check whether
a label already dumped contains an identical Uberblock. If so, do not
dump the Uberblock.
When dumping a configuration or Uberblock, state which labels it is
found in (0-3), for example: labels = 1 2 3
Detecting redundant uberblocks or configurations is accomplished by
calculating checksums of the uberblocks and the packed nvlists
containing the configuration.
If there is nothing unique to be dumped for a label (ie the
configuration and uberblocks have checksums matching those already
dumped) print nothing for that label.
With additional l's or u's, increase verbosity as follows:
-l Dump each unique configuration only once.
Indicate which labels it appears in.
-ll In addition, dump label space usage stats.
-lll Dump every configuration, unique or not.
-u Dump each unique, valid, uberblock only once.
Indicate which labels it appears in.
-uu In addition, state which slots are invalid.
-uuu Dump every uberblock, unique or not.
-uuuu Dump the uberblock blockpointer (used to be -uuu)

Fix off by one in zpl_lookup
Doing the following command would return success with zfs creating an orphan
object.
touch $(for i in $(seq 256); do printf "n"; done)
The funny thing is that this will only work once for each directory, because
after upgraded to fzap, zfs_lookup would fail properly since it has additional
length check.

Clear enclosure sysfs path from VDEV label when sysfs path isn't present
This clears vdev_enc_sysfs_path from the label if the VDEV's
/sys/class/block/<dev>/device/enclosure_device path isn't present.
This is important in the case where a disk that is labeled with
vdev_enc_sysfs_path is pulled out and put into another enclosure.
In that case, it's possible that the old sysfs path would be used to
turn on the fault LED for the disk's old slot postion, assuming the
new slot didn't have a LED sysfs entry.

panic in bpobj_space(): null pointer dereference
This is a race condition in the deadlist code.
A thread executing an administrative command that uses
dsl_deadlist_space_range() holds the lock of the whole deadlist_t to
protect the access of all its entries that the deadlist contains in an
avl tree.
Sync threads trying to insert a new entry in the deadlist (through
dsl_deadlist_insert() -> dle_enqueue()) do not hold the deadlist lock at
that moment. If the dle_bpobj is the empty bpobj (our sentinel value),
we close and reopen it. Between these two operations, it is possible
for the dsl_deadlist_space_range() thread to dereference that bpobj
which is NULL during that window.
Threads should hold the a deadlist's dl_lock when they manipulate its
internal data so scenarios like the one above are avoided.

The ziltest.sh script is a test case designed to verify the correct
functioning of the ZIL. For historical reasons it was never added
to the test suite and was always run independantly.
This change rectifies that. The existing ziltest.sh has been
translated in to `slog_015_pos.ksh` and added to the existing
slog test cases.
