a98ff31738 DTrace: re-merge remainder of r249367 (original from Illumos).
Bring back some important fixes from Illumos:

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

We particularly avoid the LD_NOLAZYLOAD changes that Illumos made
as those don't apply to FreeBSD and were causing problems in
interactive mode.

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.

This change corresponds to part of illumos-gate commit e5803b76927480:

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.

03836978be DTrace: Revert r249367
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.

3024 D integer narrowing needs some work

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.

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.

bb508e7732 Fix the zfs_ioctl compat layer to support zfs_cmd size change introduced
in r247265 (ZFS deadman thread). Both new utilities now support the old

For future backwards compatibility, the vfs.zfs.version.ioctl read-only
sysctl has been introduced. With this sysctl zfs utilities will be able
to detect the ioctl interface version of the currently loaded zfs module.

As a side effect, the zfs utilities between r247265 and this revision don't
support the old kernel module. If you are using HEAD newer or equal than
r247265, install the new kernel module (or whole kernel) first.

c622f88dd2 It is possible to recursively destroy snapshots even if the snapshot
doesn't exist on a dataset we are starting from. For example if we
have the following configuration:

	tank
	tank/foo
	tank/foo@snap
	tank/bar
	tank/bar@snap

We can execute:

	# zfs destroy -t tank@snap

eventhough tank@snap doesn't exit.

Unfortunately it is not possible to do the same with recursive rename:

	# zfs rename -r tank@snap tank@pans
	cannot open 'tank@snap': dataset does not exist

...until now. This change allows to recursively rename snapshots even if
snapshot doesn't exist on the starting dataset.

to follow the example of OpenSolaris and its descendants, which implemented
cpu as an inline that took a value out of curthread.  At certain points in
the FreeBSD scheduler curthread->td_oncpu will no longer be valid (in
particukar, just before the thread gets descheduled) so instead I have
implemented this as its own built-in variable.

Because only name is needed we don't have to read all snapshot properties.

Below you can find how long does it take to list 34509 snapshots from a single
disk pool before and after this change with cold and warm cache:

before:

	# time zfs list -t snapshot -o name -s name > /dev/null

3ebce5e218 Extend r226676 to allow rename without unmount even for file systems with
non-legacy mountpoints. It is better to be able to rename such file systems and
let them be mounted in old places until next reboot than using live CD, etc. to
rename with remount.

This is implemented by adding -u option to 'zfs rename'. If file system's
mountpoint property is set to 'legacy' or 'none', there is no need to specify -u.

Update zfs(8) manual page to reflect this addition.

497b7ef946 Allow to rename file systems without remounting if it is possible.
It is possible for file systems with 'mountpoint' preperty set to 'legacy'
or 'none' - we don't have to change mount directory for them.
Currently such file systems are unmounted on rename and not even mounted back.

This introduces layering violation, as we need to update 'f_mntfromname'
field in statfs structure related to mountpoint (for the dataset we are
renaming and all its children).

In my opinion it is worth it, as it allow to update FreeBSD in even cleaner
way - in ZFS-only configuration root file system is ZFS file system with
'mountpoint' property set to 'legacy'. If root dataset is named system/rootfs,
we can snapshot it (system/rootfs@upgrade), clone it (system/oldrootfs),
update FreeBSD and if it doesn't boot we can boot back from system/oldrootfs
and rename it back to system/rootfs while it is mounted as /. Before it was
not possible, because unmounting / was not possible.

For snapshots, this is the same as COMPRESSRATIO, but for

This is needed to figure out how much space a filesystem would use if it

4f1f4356f3 Fix 'zfs allow' (maybe not only) returning:
cannot access dataset system/usr/home: Operation not supported

by including libzfs_impl.h. What libzfs_impl.h does is to redefine ioctl() to
be compatible with OpenSolaris. More specifically OpenSolaris returns ENOMEM
when buffer is too small and sets field zc_nvlist_dst_size to the size that
will be big enough for the data. In FreeBSD case ioctl() doesn't copy data
structure back in case of a failure. We work-around it in kernel and libzfs by
returning 0 from ioctl() and always checking if zc_nvlist_dst_size hasn't
changed. For this work-around to work in pyzfs we need this compatible ioctl()
which is implemented in libzfs_impl.h.

0f2bd1e89d Add libdtrace support for tracing userland programs.
Summary of changes:
* Implement a compatibility shim between Solaris libproc and our
libproc and remove several ifdefs because of this.
* Port the drti to FreeBSD.
* Implement the missing DOODAD sections
* Link with libproc and librtld_db
* Support for ustack, jstack and uregs (by sson@)
* Misc bugfixing

When writing the SUWN_dof section, we had to resort to building the ELF
file layout by "hand". This is the job of libelf, but our libelf doesn't
support this yet. When libelf is fixed, we can remove the code under
#ifdef BROKEN_LIBELF.

1e634b7b65 proc_wait() was replaced by proc_wstatus(). Right now this call is
useless because userland support is not working on HEAD, but this makes
libdtrace compile again.

556cb98d95 dtrace: correctly map sections to addresses in elf object modules (amd64)
Unlike for modules with dso type, in elf object modules all the sections
have virtual address of zero.  So, it is insufficient to add module base
address to section virtual address (as recorded in section header) to
get section address in kernel memory.
Instead, we should apply the same calculations that are performed by
kernel loaders (in boot code and in kernel) when they lay out sections
in memory.
Also, unlike OpenSolaris, the sections are not collapsed into just .text,
.data and .bss by module loaders, so we need to take additional care
about other sections.

Note that in-kernel symbol-to-address mapping worked just fine, e.g. fbt
provider could correctly find the functions, etc.  It's only in userland
that the mapping in both direction worked incorrectly, e.g. in stack()
output addresses of functions in kernel modules were not translated to
their names.

33ae3dfefd Unbreak platforms with char unsigned by default. Oddly enough, GCC isn't
satisfied with a simple cast to int in the check against EOF, so the fix
is a bit involved by actually having to go through a temporary variable.

e9bc68ba9c In dtrace lexer, do not unput token if it is EOF.
This is harmless with OpenSolaris fex and yacc, but with FreeBSD
causes '\xff' symbol to be physically put into input buffer, causing

1ba4a712dd Update ZFS from version 6 to 13 and bring some FreeBSD-specific changes.
This bring huge amount of changes, I'll enumerate only user-visible changes:

- Delegated Administration

	Allows regular users to perform ZFS operations, like file system
	creation, snapshot creation, etc.

- L2ARC

	Level 2 cache for ZFS - allows to use additional disks for cache.
	Huge performance improvements mostly for random read of mostly
	static content.

- slog

	Allow to use additional disks for ZFS Intent Log to speed up
	operations like fsync(2).

- vfs.zfs.super_owner

	Allows regular users to perform privileged operations on files stored
	on ZFS file systems owned by him. Very careful with this one.

- chflags(2)

	Not all the flags are supported. This still needs work.

- ZFSBoot

	Support to boot off of ZFS pool. Not finished, AFAIK.

	Submitted by:	dfr

- Snapshot properties

- New failure modes

	Before if write requested failed, system paniced. Now one
	can select from one of three failure modes:
	- panic - panic on write error
	- wait - wait for disk to reappear
	- continue - serve read requests if possible, block write requests

- Refquota, refreservation properties

	Just quota and reservation properties, but don't count space consumed
	by children file systems, clones and snapshots.

- Sparse volumes

	ZVOLs that don't reserve space in the pool.

- External attributes

	Compatible with extattr(2).

- NFSv4-ACLs

	Not sure about the status, might not be complete yet.

	Submitted by:	trasz

- Creation-time properties

- Regression tests for zpool(8) command.

* Use functions in FreeBSD's process library rather than the CDDL

  Sun wouldn't release the libproc.h header under a BSD license.

  the other but not both. For us to keep using FreeBSD header files,
  we need to use endian definitions the same way we do in pure BSD

@118491	Show backtrace on unexpected code paths.

@118494	Integrate changes from vendor.

@118504	Fix sendfile(2). I had two ways of fixing it:
	1. Fixing sendfile(2) itself to use VOP_GETPAGES() instead of
	   hacking around with vn_rdwr(UIO_NOCOPY), which was suggested
	   by ups.
	2. Modify ZFS behaviour to handle this special case.

	Although 1 is more correct, I've choosen 2, because hack from 1
	have a side-effect of beeing faster - it reads ahead MAXBSIZE
	bytes instead of reading page by page. This is not easy to implement
	with VOP_GETPAGES(), at least not for me in this very moment.
