2bdf7f79bc MFV r266766:
Add a new zfs property, "redundant_metadata" which can have values "all" or
"most".  The default will be "all", which is the current behavior.  When set
to all, ZFS stores an extra copy of all metadata.  If a single on-disk block
is corrupt, at worst a single block of user data (which is recordsize bytes
long) can be lost.

Setting to "most" will cause us to only store 1 copy of level-1 indirect
blocks of user data files.  This can improve performance of random writes,
because less metadata has to be written.  In practice,  at worst about
100 blocks (of recordsize bytes each) of user data can be lost if a single
on-disk block is corrupt.

The exact behavior of which metadata blocks are stored redundantly may change
in future releases.

Illumos issue: 3835 zfs need not store 2 copies of all metadata

f3ce69748f Explicitly link libzfs against libavl as it is done in OpenSolaris
(4543:12bb2876a62e).  Without this, some third party applications
may break because the lack of AVL related symbols.

FreeBSD base system are not affected because the FreeBSD ZFS command
line tools were all linked against libavl and thus hide the underlying
issue.

2f28ceeb34 Bind ip/tcp/udp provider translators and symbols to the same versions as in
illumos, rather than using "1.0" everywhere.

Some of the translators use D functions that are not present in version
1.0 (e.g. inet_ntoa()) which can result in libdtrace crashing when running
scripts that restrict themselves to version 1.0
(e.g. with "-x version=1.0").

7585c68486 Comment out some pointless device open/close around reading device IDs.
FreeBSD ZFS port unlike OpenSolaris does not use device IDs, and does not
implement respective devid_*() fuctions.  It is pointless to open devices
just to close them back immediately.

afb8674c79 Import adapted OpenSolaris' thread pool API implementation.
The thread pool is used by libzfs to implement parallel disk scanning.
Without this change our dummy wrapper made `zpool import ZZZ` command to
scan all disks sequentially from the single thread when searching for pools.
This change makes it use two threads per CPU, same as in OpenSolaris.

On system with 200 HDDs this change reduces ZFS pool import time from 35
to 22 seconds.

f0736f4cec Re-apply r248644. This fixes an annoying problem which caused dtrace -c to
fail to attach to stripped binaries. With the _r_debug_postinit symbol,
dtrace(1) can now set a breakpoint in the victim process after it has
registered its DOF table(s) with the kernel. r_debug_state cannot be used
for this purpose since it is called before DOF is made available, in which
case dtrace(1) cannot create USDT probes before the program begins
execution.

38f0b757fd Add placeholder Kyuafiles for various top-level hierarchies.
This change adds tests/ directories in the source tree to create various
subdirectories in /usr/tests/ and to install placeholder Kyuafiles for
them.

the relevant hierarchies are: cddl, etc, games, gnu and secure.

The reason for this is to simplify the addition of new test programs for
utilities or libraries under any of these directories.  Doing so on a
case by case basis is unnecessary and is quite an obscure process.

537650f54d Add property and sysctl to control how ZVOLs are exposed to OS.
New ZFS property volmode and sysctl vfs.zfs.vol.mode allow switching ZVOL
between three modes:
 geom -- existing fully functional behavior (default);
 dev -- exposing volumes only as raw disk device file in devfs;
 none -- not exposing volumes outside ZFS.

The "dev" mode is less functional (can't be partitioned, mounted, etc),
but it is faster, and in some scenarios with untrusted consumers safer.
It can be useful for NAS, VM block storages, etc.
The "none" mode may be convenient for backup servers, etc. that don't
need direct data access.

Due to the way ZVOL is integrated with main ZFS code, those property
and sysctl are checked only during pool import and volume creation.

44c25a3d82 When our linker merges .SUNW_dof sections from multiple files, it simply
concatenates the DOF tables into one section. Previously, the USDT init
code in drti.o would only look at the first table in the DOF section; with
this change, it iterates over all the tables, passing each DOF table to
the kernel.

d32f014939 Clang 3.4 will sometimes emit DIE for struct/union member before
emitting the DIE for the type of that member. ctfconvert can not
handle this properly and will calculate a wrong member bit offset.
Same struct/union type from different .o file will be treated as
different types when their member bit offsets are different, and
gets added/merged multiple times. This will in turn cause many other
structs/pointers/typedefs that refer to the duplicated struct/union
gets added/merged multiple times and eventually causes numerous
duplicated CTF types in the kernel.debug file.

The simple workaround here is to make use of DW_AT_byte_size attribute
of the member DIE to calculate the bits occupied by the member's type,
without actually resolving the type.

34140e78ab 734 taskq_dispatch_prealloc() desired
943 zio_interrupt ends up calling taskq_dispatch with TQ_SLEEP
illumos/illumos-gate@5aeb94743e

Essentially FreeBSD taskqueues already operate in a mode that
was added to Illumos with taskq_dispatch_ent change.
We even exposed the superior FreeBSD interface as taskq_dispatch_safe.
Now we just rename taskq_dispatch_safe to taskq_dispatch_ent and
struct struct ostask to taskq_ent_t, so that code differences will be
minimal.

After this change sys/cddl/compat/opensolaris/sys/taskq.h header is no
longer needed.

e572bc11ec Add a function, memstr, which can be used to convert a buffer of
null-separated strings to a single string. This can be used to print the
full arguments of a process using execsnoop (from the DTrace toolkit) or
with the following one-liner:

dtrace -n 'syscall::execve:return {trace(curpsinfo->pr_psargs);}'

Note that this relies on the process arguments being cached via the struct
proc, which means that it will not work for argvs longer than
kern.ps_arg_cache_limit. However, the following rather non-portable
script can be used to extract any argv at exec time:

fbt::kern_execve:entry
{
    printf("%s", memstr(args[1]->begin_argv, ' ',
        args[1]->begin_envv - args[1]->begin_argv));
}

The debug.dtrace.memstr_max sysctl limits the maximum argument size to
memstr(). Thanks to Brendan Gregg for helpful comments on freebsd-dtrace.

439d30d121 Enhance the ZFS vdev layer to maintain both a logical and a physical
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.

Sponsored by:	Spectra Logic Corporaion
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.

	just ashift before) and physical ashift are reported.

	Add two new fields, vdev_physical_ashift and vdev_logical_ashift,

	Add text for the VDEV_AUX_ASHIFT_TOO_BIG error.

	This status is reported on healthy pools containing vdevs
	configured to use a block size smaller than their reported
	physical block size.

cddl/contrib/opensolaris/lib/libzfs/common/libzfs_status.c:
	Update find_vdev_problem() and supporting functions to
	provide the full vdev_stat_t structure to problem checking
	routines, and to allow decent into replacing vdevs.

	Add a vdev_non_native_ashift() validator which is used on
	the full vdev tree to check for ZPOOL_STATUS_NON_NATIVE_ASHIFT.

cddl/contrib/opensolaris/lib/libzpool/common/kernel.c:
cddl/contrib/opensolaris/lib/libzpool/common/sys/zfs_context.h:

sys/cddl/contrib/opensolaris/uts/common/fs/zfs/sys/metaslab_impl.h:
	When the group membership of a metaslab class changes (i.e.
	when a vdev is added or removed from a pool), walk the group
	list to determine the smallest block size currently available
	and record this in the metaslab class.

sys/cddl/contrib/opensolaris/uts/common/fs/zfs/sys/metaslab.h:
sys/cddl/contrib/opensolaris/uts/common/fs/zfs/metaslab.c:
	Add the metaslab_class_get_minblocksize() accessor.

sys/cddl/contrib/opensolaris/uts/common/fs/zfs/zio_compress.c:
sys/cddl/contrib/opensolaris/uts/common/fs/zfs/arc.c:
	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.

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

18161786c6 Port the SDT test now that it's possible to create SDT probes that take
seven arguments.

The original test uses Solaris' uadmin system call to trigger the test
probe; this change adds a sysctl to the dtrace_test module and gets the test
program to trigger the test probe via the sysctl handler.

The test is currently failing on amd64 because of some bugs in the way that
probe arguments beyond the first five are obtained - these bugs will be
fixed in a separate change.

09e6105ff4 Bring back part of r249367 by adding DTrace's temporal option, which allows
users to guarantee that the output of DTrace scripts will be time-ordered.
This option is enabled by adding the line

  #pragma D option temporal

to the beginning of a script, or by adding '-x temporal' to the arguments of
dtrace(1).

This change fixes a bug in the original port of the temporal option. This
bug was causing some assertions to fail, so they had been disabled; in this
revision the assertions are working properly and are enabled.

The DTrace version number has been bumped from 1.9.0 to 1.9.1 to reflect
the language change that's being introduced.

5d33cbbf9d revert r248644 because of the regression for usdt probes
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.

This change bumps the DT_VERS_* number to 1.9.1 in

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.

83b4af1142 ZFS expects a copyout of zfs_cmd_t on an ioctl error. Our sys_ioctl()
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.

Merge change from illumos:

1368 enablings on defunct providers prevent providers from unregistering

We try to address some underlying differences between the Solaris
and FreeBSD implementations: dtrace_attach() / dtrace_detach() are
currently unimplemented in FreeBSD but the new code from illumos
makes use of taskq so some adaptations were made to dtrace_open()
and dtrace_close() to handle them appropriately.
