These programs and everything using libzpool rely on the embedded asserts to
verify the correctness of operations. Given that, the core dumps would be
useless without debug symbols.

minimum allocation size for devices. Use this information to
automatically increase ZFS's minimum allocation size for new top-level
vdevs to a value that more closely matches the optimum device
allocation size.
Use GEOM's stripesize attribute, if set, as the physical sector
size of the GEOM.
Calculate the minimum blocksize of each metaslab class. Use the
calculated value instead of SPA_MINBLOCKSIZE (512b) when determining
the likelyhood of compression yeilding a reduction in physical space
usage.
Report devices with sub-optimal block size configuration in "zpool
status". Also properly fail attempts to attach devices with a
logical block size greater than 8kB, since this will cause corruption
to ZFS's label area.

MFC after: 2 weeks
Background
==========
Many modern devices use physical allocation units that are much
larger than the minimum logical allocation size accessible by
external commands. Two prevalent examples of this are 512e disk
drives (512b logical sector, 4K physical sector) and flash devices
(512b logical sector, 4K or larger allocation block size, and 128k
or larger erase block size). Operations that modify less than the
physical sector size result in a costly read-modify-write or garbage
collection sequence on these devices.
Simply exporting the true physical sector of the device to ZFS would
yield optimal performance, but has two serious drawbacks:
1) Existing pools created with devices that have different logical
and physical block sizes, but were configured to use the logical
block size (e.g. because the OS version used for pool construction
reported the logical block size instead of the physical block
size) will suddenly find that the vdev allocation size has
increased. This can be easily tolerated for active members of
the array, but ZFS would prevent replacement of a vdev with
another identical device because it now appears that the smaller
allocation size required by the pool is not supported by the new
device.
2) The device's physical block size may be too large to be supported
by ZFS. The optimal allocation size for the vdev may be quite
large. For example, a RAID controller may export a vdev that
requires read-modify-write cycles unless accessed using 64k
aligned/sized requests. ZFS currently has an 8k minimum block
size limit.
Reporting both the logical and physical allocation sizes for vdevs
solves these problems. A device may be used so long as the logical
block size is compatible with the configuration. By comparing the
logical and physical block sizes, new configurations can be optimized
and administrators can be notified of any existing pools that are
sub-optimal.
sys/cddl/contrib/opensolaris/uts/common/fs/zfs/sys/spa.h:
Add the SPA_ASHIFT constant. ZFS currently has a hard upper
limit of 13 (8k) for ashift and this constant is used to
both document and enforce this limit.
sys/cddl/contrib/opensolaris/uts/common/sys/fs/zfs.h:
Add the VDEV_AUX_ASHIFT_TOO_BIG error code.
Add fields for exporting the configured, logical, and
physical ashift to the vdev_stat_t structure.
Add VDEV_STAT_VALID() macro which can be used to verify the
presence of required vdev_stat_t fields in nvlist data.
sys/cddl/contrib/opensolaris/uts/common/fs/zfs/vdev.c:
Provide a SYSCTL_PROC handler for "max_auto_ashift". Since
the limit is only referenced long after boot when a create
operation occurs, there's no compelling need for it to be
a boot time configurable tunable. This also allows the
validation code for the max_auto_ashift value to be contained
within the sysctl handler.
Populate the new fields in the vdev_stat_t structure.
Fail vdev opens if the vdev reports an ashift larger than
SPA_MAXASHIFT.
Propogate vdev_logical_ashift and vdev_physical_ashift between
child and parent vdevs as is done for vdev_ashift.
In vdev_open(), restore code that fails opens for devices
where vdev_ashift grows. This can only happen now if the
device's logical ashift grows, which means it really isn't
safe to use the device.

This status is reported on healthy pools containing vdevs

physical block size.
cddl/contrib/opensolaris/lib/libzfs/common/libzfs_status.c:
Update find_vdev_problem() and supporting functions to

In zio_compress_data(), take the minimum blocksize as an
input parameter instead of assuming SPA_MINBLOCKSIZE.
sys/cddl/contrib/opensolaris/uts/common/fs/zfs/arc.c:
In l2arc_compress_buf(), pass SPA_MINBLOCKSIZE as the minimum
blocksize of the device. The l2arc code performs has it's own
code for deciding if compression is worth while, so this
effectively disables zio_compress_data() from second guessing
the original decision.
sys/cddl/contrib/opensolaris/uts/common/fs/zfs/zio.c:
In zio_write_bp_init(), use the minimum blocksize of the
normal metaslab class when compressing data.

Fix a regression introduced by fix for Illumos bug #3834. Quote from
Matthew Ahrens on the Illumos issue:
ztest fails this assertion because ztest_dmu_read_write() does
dmu_tx_hold_free(tx, bigobj, bigoff, bigsize);
and then
dmu_object_set_checksum(os, bigobj,
(enum zio_checksum)ztest_random_dsl_prop(ZFS_PROP_CHECKSUM), tx);
If the region to free is past the end of the file, the DMU assumes that there
will be nothing to do for this object. However, ztest does set_checksum(),
which must modify the dnode. The fix is for ztest to also call
dmu_tx_hold_bonus(tx, bigobj);
so we can account for the dirty data associated with setting the checksum

USDT probes are advertised to kernel by initialization code with
atrribute((constructor))). It seems that on Solaris the .init-ish code
of the main object is executed before RD_PREINIT point is hit. On
FreeBSD that is not the case. And because on FreeBSD there is no other
well-defined point between RD_PREINIT and main() we have to parse a
DTrace script when main is hit, for time being.
A footnote: currently we actually post RD_POSTINIT event, but that's a
bug because the event is triggered by hitting r_debug_state which
happens before any init code is executed.

The following change from illumos brought caused DTrace to
pause in an interactive environment:
3026 libdtrace should set LD_NOLAZYLOAD=1 to help the pid provider
This was not detected during testing because it doesn't
affect scripts.
We shouldn't be changing the environment, especially since the
LD_NOLAZYLOAD option doesn't apply to our (GNU) ld.
Unfortunately the change from upstream was made in such a way
that it is very difficult to separate this change from the
others so, at least for now, it's better to just revert
everything.

Merge changes from illumos:
3021 option for time-ordered output from dtrace(1M)
3022 DTrace: keys should not affect the sort order when sorting by value
3023 it should be possible to dereference dynamic variables
3024 D integer narrowing needs some work
3025 register leak in D code generation
3026 libdtrace should set LD_NOLAZYLOAD=1 to help the pid provider
This brings yet another feature implemented in upstream DTrace.
A complete description is available here:
http://dtrace.org/blogs/ahl/2012/07/28/my-new-dtrace-favorite/
This change bumps the DT_VERS_* number to 1.9.1 in
accordance to what is done in illumos.
This change was somewhat complicated because upstream is mixed many
changes in an individual commit and some of the tests don't really
apply to us.
There are also appear to be differences in timestamping with Solaris
so we had to workaround some assertions making sure no regression
happened.
Special thanks to Fabian Keil for changes and testing.

release a non-existing snapshot of a existing dataset. In recursive case
error is reported if no snapshots with the requested name have been found.
Problem and proposed solution reported to illumos:
3699 zfs hold or release of a non-existent snapshot does not output error

doesn't copyout in this case.
To solve this issue a new struct zfs_iocparm_t is introduced consisting of:
- zfs_ioctl_version (future backwards compatibility purposes)
- user space pointer to zfs_cmd_t (copyin and copyout)
- size of zfs_cmd_t (verification purposes)
The copyin and copyout of zfs_cmd_t is now done the illumos (vendor) way
what makes porting of new changes easier and ensures correct behavior if
returning an error.
