-# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
-# $ac_aux_dir to '$srcdir/foo'. In other projects, it is set to
-# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
-#
-# Of course, Automake must honor this variable whenever it calls a
-# tool from the auxiliary directory. The problem is that $srcdir (and
-# therefore $ac_aux_dir as well) can be either absolute or relative,
-# depending on how configure is run. This is pretty annoying, since
-# it makes $ac_aux_dir quite unusable in subdirectories: in the top
-# source directory, any form will work fine, but in subdirectories a
-# relative path needs to be adjusted first.
-#
-# $ac_aux_dir/missing
-# fails when called from a subdirectory if $ac_aux_dir is relative
-# $top_srcdir/$ac_aux_dir/missing
-# fails if $ac_aux_dir is absolute,
-# fails when called from a subdirectory in a VPATH build with
-# a relative $ac_aux_dir
-#
-# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
-# are both prefixed by $srcdir. In an in-source build this is usually
-# harmless because $srcdir is '.', but things will broke when you
-# start a VPATH build or use an absolute $srcdir.
-#
-# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
-# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
-# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
-# and then we would define $MISSING as
-# MISSING="\${SHELL} $am_aux_dir/missing"
-# This will work as long as MISSING is not called from configure, because
-# unfortunately $(top_srcdir) has no meaning in configure.
-# However there are other variables, like CC, which are often used in
-# configure, and could therefore not use this "fixed" $ac_aux_dir.
-#
-# Another solution, used here, is to always expand $ac_aux_dir to an
-# absolute PATH. The drawback is that using absolute paths prevent a
-# configured tree to be moved without reconfiguration.

+#
+# vdev_id: udev helper to generate user-friendly names for JBOD disks
+#
+# This script parses the file /etc/zfs/vdev_id.conf to map a
+# physical path in a storage topology to a channel name. The
+# channel name is combined with a disk enclosure slot number to
+# create an alias that reflects the physical location of the drive.
+# This is particularly helpful when it comes to tasks like replacing
+# failed drives. Slot numbers may also be re-mapped in case the
+# default numbering is unsatisfactory. The drive aliases will be
+# created as symbolic links in /dev/disk/by-vdev.
+#
+# The currently supported topologies are sas_direct and sas_switch.
+# A multipath mode is supported in which dm-mpath devices are
+# handled by examining the first-listed running component disk. In
+# multipath mode the configuration file should contain a channel
+# definition with the same name for each path to a given enclosure.
+#
+# The alias keyword provides a simple way to map already-existing
+# device symlinks to more convenient names. It is suitable for
+# small, static configurations or for sites that have some automated
+# way to generate the mapping file.
+#
+#
+# Some example configuration files are given below.

+ * 4. Attempt to online the device with a flag to indicate that it should

+ * same device was inserted and we should continue normally.
+ *
+ * 5. If the pool does not have the 'autoreplace' property set, attempt to
+ * online the device again without the unspare flag, which will
+ * generate a FMA fault.
+ *
+ * 6. If the pool has the 'autoreplace' property set, and the matching vdev
+ * is a whole disk, then label the new disk and attempt a 'zpool
+ * replace'.
+ *
+ * The module responds to EC_DEV_ADD events. The special ESC_ZFS_VDEV_CHECK
+ * event indicates that a device failed to open during pool load, but the
+ * autoreplace property was set. In this case, we deferred the associated
+ * FMA fault until our module had a chance to process the autoreplace logic.
+ * If the device could not be replaced, then the second online attempt will
+ * trigger the FMA fault that we skipped earlier.
+ *
+ * ZFS on Linux porting notes:
+ * In lieu of a thread pool, just spawn a thread on demmand.
+ * Linux udev provides a disk insert for both the disk and the partition

+/*
+ * ZFS Fault Injector
+ *
+ * This userland component takes a set of options and uses libzpool to translate
+ * from a user-visible object type and name to an internal representation.
+ * There are two basic types of faults: device faults and data faults.
+ *
+ *
+ * DEVICE FAULTS
+ *
+ * Errors can be injected into a particular vdev using the '-d' option. This
+ * option takes a path or vdev GUID to uniquely identify the device within a
+ * pool. There are two types of errors that can be injected, EIO and ENXIO,
+ * that can be controlled through the '-e' option. The default is ENXIO. For
+ * EIO failures, any attempt to read data from the device will return EIO, but
+ * subsequent attempt to reopen the device will succeed. For ENXIO failures,
+ * any attempt to read from the device will return EIO, but any attempt to
+ * reopen the device will also return ENXIO.
+ * For label faults, the -L option must be specified. This allows faults
+ * to be injected into either the nvlist, uberblock, pad1, or pad2 region
+ * of all the labels for the specified device.
+ *
+ * This form of the command looks like:
+ *
+ * zinject -d device [-e errno] [-L <uber | nvlist | pad1 | pad2>] pool
+ *
+ *
+ * DATA FAULTS
+ *
+ * We begin with a tuple of the form:
+ *
+ * <type,level,range,object>
+ *
+ * type A string describing the type of data to target. Each type
+ * implicitly describes how to interpret 'object'. Currently,
+ * the following values are supported:
+ *
+ * data User data for a file
+ * dnode Dnode for a file or directory
+ *
+ * The following MOS objects are special. Instead of injecting
+ * errors on a particular object or blkid, we inject errors across
+ * all objects of the given type.
+ *
+ * mos Any data in the MOS
+ * mosdir object directory
+ * config pool configuration
+ * bpobj blkptr list
+ * spacemap spacemap
+ * metaslab metaslab
+ * errlog persistent error log
+ *
+ * level Object level. Defaults to '0', not applicable to all types. If
+ * a range is given, this corresponds to the indirect block
+ * corresponding to the specific range.
+ *
+ * range A numerical range [start,end) within the object. Defaults to
+ * the full size of the file.
+ *
+ * object A string describing the logical location of the object. For
+ * files and directories (currently the only supported types),
+ * this is the path of the object on disk.
+ *
+ * This is translated, via libzpool, into the following internal representation:
+ *
+ * <type,objset,object,level,range>
+ *
+ * These types should be self-explanatory. This tuple is then passed to the
+ * kernel via a special ioctl() to initiate fault injection for the given
+ * object. Note that 'type' is not strictly necessary for fault injection, but
+ * is used when translating existing faults into a human-readable string.
+ *
+ *
+ * The command itself takes one of the forms:
+ *
+ * zinject
+ * zinject <-a | -u pool>
+ * zinject -c <id|all>
+ * zinject [-q] <-t type> [-f freq] [-u] [-a] [-m] [-e errno] [-l level]
+ * [-r range] <object>
+ * zinject [-f freq] [-a] [-m] [-u] -b objset:object:level:start:end pool
+ *
+ * With no arguments, the command prints all currently registered injection
+ * handlers, with their numeric identifiers.
+ *
+ * The '-c' option will clear the given handler, or all handlers if 'all' is
+ * specified.
+ *
+ * The '-e' option takes a string describing the errno to simulate. This must
+ * be either 'io' or 'checksum'. In most cases this will result in the same
+ * behavior, but RAID-Z will produce a different set of ereports for this
+ * situation.
+ *
+ * The '-a', '-u', and '-m' flags toggle internal flush behavior. If '-a' is
+ * specified, then the ARC cache is flushed appropriately. If '-u' is
+ * specified, then the underlying SPA is unloaded. Either of these flags can be
+ * specified independently of any other handlers. The '-m' flag automatically
+ * does an unmount and remount of the underlying dataset to aid in flushing the
+ * cache.
+ *
+ * The '-f' flag controls the frequency of errors injected, expressed as a
+ * integer percentage between 1 and 100. The default is 100.
+ *
+ * The this form is responsible for actually injecting the handler into the
+ * framework. It takes the arguments described above, translates them to the
+ * internal tuple using libzpool, and then issues an ioctl() to register the
+ * handler.
+ *
+ * The final form can target a specific bookmark, regardless of whether a
+ * human-readable interface has been designed. It allows developers to specify
+ * a particular block by number.

+/*
+ * The objective of this program is to provide a DMU/ZAP/SPA stress test
+ * that runs entirely in userland, is easy to use, and easy to extend.
+ *
+ * The overall design of the ztest program is as follows:
+ *
+ * (1) For each major functional area (e.g. adding vdevs to a pool,
+ * creating and destroying datasets, reading and writing objects, etc)
+ * we have a simple routine to test that functionality. These
+ * individual routines do not have to do anything "stressful".
+ *
+ * (2) We turn these simple functionality tests into a stress test by
+ * running them all in parallel, with as many threads as desired,
+ * and spread across as many datasets, objects, and vdevs as desired.
+ *
+ * (3) While all this is happening, we inject faults into the pool to
+ * verify that self-healing data really works.
+ *
+ * (4) Every time we open a dataset, we change its checksum and compression
+ * functions. Thus even individual objects vary from block to block
+ * in which checksum they use and whether they're compressed.
+ *
+ * (5) To verify that we never lose on-disk consistency after a crash,
+ * we run the entire test in a child of the main process.
+ * At random times, the child self-immolates with a SIGKILL.
+ * This is the software equivalent of pulling the power cord.
+ * The parent then runs the test again, using the existing
+ * storage pool, as many times as desired. If backwards compatibility
+ * testing is enabled ztest will sometimes run the "older" version
+ * of ztest after a SIGKILL.
+ *
+ * (6) To verify that we don't have future leaks or temporal incursions,
+ * many of the functional tests record the transaction group number
+ * as part of their data. When reading old data, they verify that
+ * the transaction group number is less than the current, open txg.
+ * If you add a new test, please do this if applicable.
+ *
+ * (7) Threads are created with a reduced stack size, for sanity checking.
+ * Therefore, it's important not to allocate huge buffers on the stack.
+ *
+ * When run with no arguments, ztest runs for about five minutes and
+ * produces no output if successful. To get a little bit of information,
+ * specify -V. To get more information, specify -VV, and so on.
+ *
+ * To turn this into an overnight stress test, use -T to specify run time.
+ *
+ * You can ask more more vdevs [-v], datasets [-d], or threads [-t]
+ * to increase the pool capacity, fanout, and overall stress level.
+ *
+ * Use the -k option to set the desired frequency of kills.
+ *
+ * When ztest invokes itself it passes all relevant information through a
+ * temporary file which is mmap-ed in the child process. This allows shared
+ * memory to survive the exec syscall. The ztest_shared_hdr_t struct is always
+ * stored at offset 0 of this file and contains information on the size and
+ * number of shared structures in the file. The information stored in this file
+ * must remain backwards compatible with older versions of ztest so that
+ * ztest can invoke them during backwards compatibility testing (-B).

-## ------ ##
-## Usage. ##
-## ------ ##
-
-# This file is a library for parsing options in your shell scripts along
-# with assorted other useful supporting features that you can make use
-# of too.
-#
-# For the simplest scripts you might need only:
-#
-# #!/bin/sh
-# . relative/path/to/funclib.sh
-# . relative/path/to/options-parser
-# scriptversion=1.0
-# func_options ${1+"$@"}
-# eval set dummy "$func_options_result"; shift
-# ...rest of your script...
-#
-# In order for the '--version' option to work, you will need to have a
-# suitably formatted comment like the one at the top of this file
-# starting with '# Written by ' and ending with '# warranty; '.
-#
-# For '-h' and '--help' to work, you will also need a one line
-# description of your script's purpose in a comment directly above the
-# '# Written by ' line, like the one at the top of this file.
-#
-# The default options also support '--debug', which will turn on shell
-# execution tracing (see the comment above debug_cmd below for another
-# use), and '--verbose' and the func_verbose function to allow your script
-# to display verbose messages only when your user has specified
-# '--verbose'.
-#
-# After sourcing this file, you can plug processing for additional
-# options by amending the variables from the 'Configuration' section
-# below, and following the instructions in the 'Option parsing'
-# section further down.
-
-## -------------- ##
-## Configuration. ##
-## -------------- ##
-
-# You should override these variables in your script after sourcing this
-# file so that they reflect the customisations you have added to the
-# option parser.
-
-# The usage line for option parsing errors and the start of '-h' and
-# '--help' output messages. You can embed shell variables for delayed
-# expansion at the time the message is displayed, but you will need to
-# quote other shell meta-characters carefully to prevent them being
-# expanded when the contents are evaled.
-usage='$progpath [OPTION]...'
-
-# Short help message in response to '-h' and '--help'. Add to this or
-# override it after sourcing this library to reflect the full set of
-# options your script accepts.
-usage_message="\
- --debug enable verbose shell tracing
- -W, --warnings=CATEGORY
- report the warnings falling in CATEGORY [all]
- -v, --verbose verbosely report processing
- --version print version information and exit
- -h, --help print short or long help message and exit
-"
-
-# Additional text appended to 'usage_message' in response to '--help'.

-# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN),

-# exported API, or moved to Autoconf or Automake where they belong.
-#
-# The trouble is, aclocal is a bit thick. It'll see the old AC_DEFUN

-# using a macro with the same name in our local m4/libtool.m4 it'll
-# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
-# and doesn't know about Autoconf macros at all.)

-# included after everything else. This provides aclocal with the
-# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
-# because those macros already exist, or will be overwritten later.
-# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.

-# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.

-Some influential environment variables:
- CC C compiler command
- CFLAGS C compiler flags
- LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
- nonstandard directory <lib dir>
- LIBS libraries to pass to the linker, e.g. -l<library>
- CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
- you have headers in a nonstandard directory <include dir>
- LT_SYS_LIBRARY_PATH
- User-defined run-time library search path.
- CPP C preprocessor
- CCAS assembler compiler command (defaults to CC)
- CCASFLAGS assembler compiler flags (defaults to CFLAGS)
-
-Use these variables to override the choices made by `configure' or to help
-it to find libraries and programs with nonstandard names/locations.
-
-Report bugs to the package provider.

+DESCRIPTION
+ These script were written with the primary intention of being portable and
+ usable on as many systems as possible.
+
+ This is, in practice, usually not possible. But the intention is there.
+ And it is a good one.
+
+ They have been tested successfully on:
+
+ * Debian GNU/Linux Wheezy
+ * Debian GNU/Linux Jessie
+ * Ubuntu Trusty
+ * CentOS 6.0
+ * CentOS 6.6
+ * Gentoo
+
+SUPPORT
+ If you find that they don't work for your platform, please report this
+ at the ZFS On Linux issue tracker at https://github.com/zfsonlinux/zfs/issues.
+
+ Please include:
+
+ * Distribution name
+ * Distribution version
+ * Where to find an install CD image
+ * Architecture
+
+ If you have code to share that fixes the problem, that is much better.
+ But please remember to try your best keep portability in mind. If you
+ suspect that what you're writing/modifying won't work on anything else
+ than your distribution, please make sure to put that code in appropriate
+ if/else/fi code.
+
+ It currently MUST be bash (or fully compatible) for this to work.
+
+ If you're making your own distribution and you want the scripts to
+ work on that, the biggest problem you'll (probably) have is the part
+ at the beginning of the "zfs-functions.in" file which sets up the
+ logging output.
+
+INSTALLING INIT SCRIPT LINKS
+ To setup the init script links in /etc/rc?.d manually on a Debian GNU/Linux
+ (or derived) system, run the following commands (the order is important!):
+
+ update-rc.d zfs-import start 07 S . stop 07 0 1 6 .
+ update-rc.d zfs-mount start 02 2 3 4 5 . stop 06 0 1 6 .
+ update-rc.d zfs-zed start 07 2 3 4 5 . stop 08 0 1 6 .
+ update-rc.d zfs-share start 27 2 3 4 5 . stop 05 0 1 6 .
+
+ To do the same on RedHat, Fedora and/or CentOS:
+
+ chkconfig zfs-import
+ chkconfig zfs-mount
+ chkconfig zfs-zed
+ chkconfig zfs-share
+
+ On Gentoo:
+
+ rc-update add zfs-import boot
+ rc-update add zfs-mount boot
+ rc-update add zfs-zed default
+ rc-update add zfs-share default
+
+ The idea here is to make sure all of the ZFS filesystems, including possibly
+ separate datasets like /var, are mounted before anything else is started.
+
+ Then, ZED, which depends on /var, can be started. It will consume and act
+ on events that occurred before it started. ZED may also play a role in
+ sharing filesystems in the future, so it is important to start before the
+ 'share' service.
+
+ Finally, we share filesystems configured with the share\* property.

+ * This is an addition to the zfs device driver to add, modify and remove SMB
+ * shares using the 'net share' command that comes with Samba.
+ *
+ * TESTING
+ * Make sure that samba listens to 'localhost' (127.0.0.1) and that the options
+ * 'usershare max shares' and 'usershare owner only' have been rewied/set
+ * accordingly (see zfs(8) for information).
+ *
+ * Once configuration in samba have been done, test that this
+ * works with the following three commands (in this case, my ZFS
+ * filesystem is called 'share/Test1'):
+ *
+ * (root)# net -U root -S 127.0.0.1 usershare add Test1 /share/Test1 \
+ * "Comment: /share/Test1" "Everyone:F"
+ * (root)# net usershare list | grep -i test
+ * (root)# net -U root -S 127.0.0.1 usershare delete Test1
+ *
+ * The first command will create a user share that gives everyone full access.
+ * To limit the access below that, use normal UNIX commands (chmod, chown etc).

+ * For persistent kstats, indicates that the kstat is in the

+ * Dynamic update support
+ *
+ * The kstat mechanism allows for an optional ks_update function to update
+ * kstat data. This is useful for drivers where the underlying device
+ * keeps cheap hardware stats, but extraction is expensive. Instead of
+ * constantly keeping the kstat data section up to date, you can supply a
+ * ks_update function which updates the kstat's data section on demand.
+ * To take advantage of this feature, simply set the ks_update field before
+ * calling kstat_install().
+ *
+ * The ks_update function, if supplied, must have the following structure:
+ *
+ * int
+ * foo_kstat_update(kstat_t *ksp, int rw)
+ * {
+ * if (rw == KSTAT_WRITE) {
+ * ... update the native stats from ksp->ks_data;
+ * return EACCES if you don't support this
+ * } else {
+ * ... update ksp->ks_data from the native stats
+ * }
+ * }
+ *
+ * The ks_update return codes are: 0 for success, EACCES if you don't allow
+ * KSTAT_WRITE, and EIO for any other type of error.
+ *
+ * In general, the ks_update function may need to refer to provider-private
+ * data; for example, it may need a pointer to the provider's raw statistics.
+ * The ks_private field is available for this purpose. Its use is entirely
+ * at the provider's discretion.
+ *
+ * All variable-size kstats MUST supply a ks_update routine, which computes
+ * and sets ks_data_size (and ks_ndata if that is meaningful), since these
+ * are needed to perform kstat snapshots (see below).
+ *
+ * No kstat locking should be done inside the ks_update routine. The caller
+ * will already be holding the kstat's ks_lock (to ensure consistent data).
+ */
+

+
+/*
+ * Kstat snapshot
+ *
+ * In order to get a consistent view of a kstat's data, clients must obey
+ * the kstat's locking strategy. However, these clients may need to perform
+ * operations on the data which could cause a fault (e.g. copyout()), or
+ * operations which are simply expensive. Doing so could cause deadlock
+ * (e.g. if you're holding a disk's kstat lock which is ultimately required
+ * to resolve a copyout() fault), performance degradation (since the providers'
+ * activity is serialized at the kstat lock), device timing problems, etc.
+ *
+ * To avoid these problems, kstat data is provided via snapshots. Taking
+ * a snapshot is a simple process: allocate a wired-down kernel buffer,
+ * acquire the kstat's data lock, copy the data into the buffer ("take the
+ * snapshot"), and release the lock. This ensures that the kstat's data lock
+ * will be held as briefly as possible, and that no faults will occur while
+ * the lock is held.
+ *
+ * Normally, the snapshot is taken by default_kstat_snapshot(), which
+ * timestamps the data (sets ks_snaptime), copies it, and does a little
+ * massaging to deal with incomplete transactions on i/o kstats. However,
+ * this routine only works for kstats with contiguous data (the typical case).
+ * If you create a kstat whose data is, say, a linked list, you must provide
+ * your own ks_snapshot routine. The routine you supply must have the
+ * following prototype (replace "foo" with something appropriate):
+ *
+ * int foo_kstat_snapshot(kstat_t *ksp, void *buf, int rw);
+ *
+ * The minimal snapshot routine -- one which copies contiguous data that
+ * doesn't need any massaging -- would be this:
+ *
+ * ksp->ks_snaptime = gethrtime();
+ * if (rw == KSTAT_WRITE)
+ * bcopy(buf, ksp->ks_data, ksp->ks_data_size);
+ * else
+ * bcopy(ksp->ks_data, buf, ksp->ks_data_size);
+ * return (0);
+ *
+ * A more illuminating example is taking a snapshot of a linked list:
+ *
+ * ksp->ks_snaptime = gethrtime();
+ * if (rw == KSTAT_WRITE)
+ * return (EACCES); ... See below ...
+ * for (foo = first_foo; foo; foo = foo->next) {
+ * bcopy((char *) foo, (char *) buf, sizeof (struct foo));
+ * buf = ((struct foo *) buf) + 1;
+ * }
+ * return (0);
+ *
+ * In the example above, we have decided that we don't want to allow
+ * KSTAT_WRITE access, so we return EACCES if this is attempted.
+ *
+ * The key points are:
+ *
+ * (1) ks_snaptime must be set (via gethrtime()) to timestamp the data.
+ * (2) Data gets copied from the kstat to the buffer on KSTAT_READ,
+ * and from the buffer to the kstat on KSTAT_WRITE.
+ * (3) ks_snapshot return values are: 0 for success, EACCES if you
+ * don't allow KSTAT_WRITE, and EIO for any other type of error.
+ *
+ * Named kstats (see section on "Named statistics" below) containing long
+ * strings (KSTAT_DATA_STRING) need special handling. The kstat driver
+ * assumes that all strings are copied into the buffer after the array of
+ * named kstats, and the pointers (KSTAT_NAMED_STR_PTR()) are updated to point
+ * into the copy within the buffer. The default snapshot routine does this,
+ * but overriding routines should contain at least the following:
+ *
+ * if (rw == KSTAT_READ) {
+ * kstat_named_t *knp = buf;
+ * char *end = knp + ksp->ks_ndata;
+ * uint_t i;
+ *
+ * ... Do the regular copy ...
+ * bcopy(ksp->ks_data, buf, sizeof (kstat_named_t) * ksp->ks_ndata);
+ *
+ * for (i = 0; i < ksp->ks_ndata; i++, knp++) {
+ * if (knp[i].data_type == KSTAT_DATA_STRING &&
+ * KSTAT_NAMED_STR_PTR(knp) != NULL) {
+ * bcopy(KSTAT_NAMED_STR_PTR(knp), end,
+ * KSTAT_NAMED_STR_BUFLEN(knp));
+ * KSTAT_NAMED_STR_PTR(knp) = end;

+ *
+ * At each change of state (entry or exit from the queue),

+ * to the active time if the queue length was non-zero during
+ * that interval; and we add the product of the elapsed time
+ * times the queue length to the running length*time sum.
+ *
+ * This method is generalizable to measuring residency
+ * in any defined system: instead of queue lengths, think
+ * of "outstanding RPC calls to server X".
+ *
+ * A large number of I/O subsystems have at least two basic
+ * "lists" of transactions they manage: one for transactions
+ * that have been accepted for processing but for which processing
+ * has yet to begin, and one for transactions which are actively
+ * being processed (but not done). For this reason, two cumulative
+ * time statistics are defined here: wait (pre-service) time,
+ * and run (service) time.
+ *
+ * All times are 64-bit nanoseconds (hrtime_t), as returned by
+ * gethrtime().
+ *
+ * The units of cumulative busy time are accumulated nanoseconds.
+ * The units of cumulative length*time products are elapsed time

+ *
+ * kstat_waitq_to_runq() (see below)
+ * kstat_runq_back_to_waitq() (see below)
+ *
+ * Since kstat_waitq_exit() is typically followed immediately
+ * by kstat_runq_enter(), there is a single kstat_waitq_to_runq()
+ * function which performs both operations. This is a performance
+ * win since only one timestamp is required.
+ *
+ * In some instances, it may be necessary to move a request from
+ * the run queue back to the wait queue, e.g. for write throttling.

+ * Adding and deleting kstats.
+ *
+ * The typical sequence to add a kstat is:
+ *
+ * ksp = kstat_create(module, instance, name, class, type, ndata, flags);
+ * if (ksp) {
+ * ... provider initialization, if necessary
+ * kstat_install(ksp);
+ * }
+ *
+ * There are three logically distinct steps here:
+ *
+ * Step 1: System Initialization (kstat_create)
+ *
+ * kstat_create() performs system initialization. kstat_create()
+ * allocates memory for the entire kstat (header plus data), initializes
+ * all header fields, initializes the data section to all zeroes, assigns
+ * a unique KID, and puts the kstat onto the system's kstat chain.
+ * The returned kstat is marked invalid (KSTAT_FLAG_INVALID is set),
+ * because the provider (caller) has not yet had a chance to initialize
+ * the data section.
+ *
+ * By default, kstats are exported to all zones on the system. A kstat may be
+ * created via kstat_create_zone() to specify a zone to which the statistics
+ * should be exported. kstat_zone_add() may be used to specify additional
+ * zones to which the statistics are to be exported.
+ *
+ * Step 2: Provider Initialization
+ *
+ * The provider performs any necessary initialization of the data section,
+ * e.g. setting the name fields in a KSTAT_TYPE_NAMED. Virtual kstats set
+ * the ks_data field at this time. The provider may also set the ks_update,
+ * ks_snapshot, ks_private, and ks_lock fields if necessary.
+ *
+ * Step 3: Installation (kstat_install)
+ *
+ * Once the kstat is completely initialized, kstat_install() clears the
+ * INVALID flag, thus making the kstat accessible to the outside world.
+ * kstat_install() also clears the DORMANT flag for persistent kstats.
+ *
+ * Removing a kstat from the system
+ *
+ * kstat_delete(ksp) removes ksp from the kstat chain and frees all
+ * associated system resources. NOTE: When you call kstat_delete(),
+ * you must NOT be holding that kstat's ks_lock. Otherwise, you may
+ * deadlock with a kstat reader.
+ *
+ * Persistent kstats
+ *
+ * From the provider's point of view, persistence is transparent. The only
+ * difference between ephemeral (normal) kstats and persistent kstats
+ * is that you pass KSTAT_FLAG_PERSISTENT to kstat_create(). Magically,
+ * this has the effect of making your data visible even when you're
+ * not home. Persistence is important to tools like iostat, which want
+ * to get a meaningful picture of disk activity. Without persistence,
+ * raw disk i/o statistics could never accumulate: they would come and
+ * go with each open/close of the raw device.
+ *
+ * The magic of persistence works by slightly altering the behavior of
+ * kstat_create() and kstat_delete(). The first call to kstat_create()
+ * creates a new kstat, as usual. However, kstat_delete() does not
+ * actually delete the kstat: it performs one final update of the data
+ * (i.e., calls the ks_update routine), marks the kstat as dormant, and
+ * sets the ks_lock, ks_update, ks_private, and ks_snapshot fields back
+ * to their default values (since they might otherwise point to garbage,
+ * e.g. if the provider is going away). kstat clients can still access
+ * the dormant kstat just like a live kstat; they just continue to see
+ * the final data values as long as the kstat remains dormant.
+ * All subsequent kstat_create() calls simply find the already-existing,
+ * dormant kstat and return a pointer to it, without altering any fields.
+ * The provider then performs its usual initialization sequence, and
+ * calls kstat_install(). kstat_install() uses the old data values to
+ * initialize the native data (i.e., ks_update is called with KSTAT_WRITE),
+ * thus making it seem like you were never gone.

+/*
+ * LibZFS_Core (lzc) is intended to replace most functionality in libzfs.
+ * It has the following characteristics:
+ *
+ * - Thread Safe. libzfs_core is accessible concurrently from multiple
+ * threads. This is accomplished primarily by avoiding global data
+ * (e.g. caching). Since it's thread-safe, there is no reason for a
+ * process to have multiple libzfs "instances". Therefore, we store
+ * our few pieces of data (e.g. the file descriptor) in global
+ * variables. The fd is reference-counted so that the libzfs_core
+ * library can be "initialized" multiple times (e.g. by different
+ * consumers within the same process).
+ *
+ * - Committed Interface. The libzfs_core interface will be committed,
+ * therefore consumers can compile against it and be confident that
+ * their code will continue to work on future releases of this code.
+ * Currently, the interface is Evolving (not Committed), but we intend
+ * to commit to it once it is more complete and we determine that it
+ * meets the needs of all consumers.
+ *
+ * - Programmatic Error Handling. libzfs_core communicates errors with
+ * defined error numbers, and doesn't print anything to stdout/stderr.
+ *
+ * - Thin Layer. libzfs_core is a thin layer, marshaling arguments
+ * to/from the kernel ioctls. There is generally a 1:1 correspondence
+ * between libzfs_core functions and ioctls to /dev/zfs.
+ *
+ * - Clear Atomicity. Because libzfs_core functions are generally 1:1
+ * with kernel ioctls, and kernel ioctls are general atomic, each
+ * libzfs_core function is atomic. For example, creating multiple
+ * snapshots with a single call to lzc_snapshot() is atomic -- it
+ * can't fail with only some of the requested snapshots created, even
+ * in the event of power loss or system crash.
+ *
+ * - Continued libzfs Support. Some higher-level operations (e.g.
+ * support for "zfs send -R") are too complicated to fit the scope of
+ * libzfs_core. This functionality will continue to live in libzfs.
+ * Where appropriate, libzfs will use the underlying atomic operations
+ * of libzfs_core. For example, libzfs may implement "zfs send -R |
+ * zfs receive" by using individual "send one snapshot", rename,
+ * destroy, and "receive one snapshot" operations in libzfs_core.
+ * /sbin/zfs and /zbin/zpool will link with both libzfs and
+ * libzfs_core. Other consumers should aim to use only libzfs_core,
+ * since that will be the supported, stable interface going forwards.

+.SH NAME
+.I cstyle
+\- check for some common stylistic errors in C source files
+.SH SYNOPSIS
+\fBcstyle [-chpvCP] [-o constructs] [file...]\fP
+.LP
+.SH DESCRIPTION
+.IX "OS-Net build tools" "cstyle" "" "\fBcstyle\fP"
+.LP
+.I cstyle
+inspects C source files (*.c and *.h) for common sylistic errors. It
+attempts to check for the cstyle documented in
+\fIhttp://www.cis.upenn.edu/~lee/06cse480/data/cstyle.ms.pdf\fP.
+Note that there is much in that document that
+.I cannot
+be checked for; just because your code is \fBcstyle(1)\fP clean does not
+mean that you've followed Sun's C style. \fICaveat emptor\fP.
+.LP
+.SH OPTIONS
+.LP
+The following options are supported:
+.TP 4
+.B \-c
+Check continuation line indentation inside of functions. Sun's C style
+states that all statements must be indented to an appropriate tab stop,
+and any continuation lines after them must be indented \fIexactly\fP four
+spaces from the start line. This option enables a series of checks
+designed to find continuation line problems within functions only. The
+checks have some limitations; see CONTINUATION CHECKING, below.
+.LP
+.TP 4
+.B \-h
+Performs heuristic checks that are sometimes wrong. Not generally used.
+.LP
+.TP 4
+.B \-p
+Performs some of the more picky checks. Includes ANSI #else and #endif
+rules, and tries to detect spaces after casts. Used as part of the
+putback checks.
+.LP
+.TP 4
+.B \-v
+Verbose output; includes the text of the line of error, and, for
+\fB-c\fP, the first statement in the current continuation block.
+.LP
+.TP 4
+.B \-C
+Ignore errors in header comments (i.e. block comments starting in the
+first column). Not generally used.
+.LP
+.TP 4
+.B \-P
+Check for use of non-POSIX types. Historically, types like "u_int" and
+"u_long" were used, but they are now deprecated in favor of the POSIX
+types uint_t, ulong_t, etc. This detects any use of the deprecated
+types. Used as part of the putback checks.
+.LP
+.TP 4
+.B \-o \fIconstructs\fP
+Allow a comma-separated list of additional constructs. Available
+constructs include:
+.LP
+.TP 10
+.B doxygen
+Allow doxygen-style block comments (\fB/**\fP and \fB/*!\fP)
+.LP
+.TP 10
+.B splint
+Allow splint-style lint comments (\fB/*@...@*/\fP)
+.LP
+.SH NOTES
+.LP
+The cstyle rule for the OS/Net consolidation is that all new files must
+be \fB-pP\fP clean. For existing files, the following invocations are
+run against both the old and new files:
+.LP
+.TP 4
+\fBcstyle file\fB
+.LP
+.TP 4
+\fBcstyle -p file\fB
+.LP
+.TP 4
+\fBcstyle -pP file\fB
+.LP
+If the old file gave no errors for one of the invocations, the new file
+must also give no errors. This way, files can only become more clean.
+.LP
+.SH CONTINUATION CHECKING
+.LP
+The continuation checker is a reasonably simple state machine that knows
+something about how C is laid out, and can match parenthesis, etc. over
+multiple lines. It does have some limitations:
+.LP
+.TP 4
+.B 1.
+Preprocessor macros which cause unmatched parenthesis will confuse the
+checker for that line. To fix this, you'll need to make sure that each
+branch of the #if statement has balanced parenthesis.
+.LP
+.TP 4
+.B 2.
+Some \fBcpp\fP macros do not require ;s after them. Any such macros
+*must* be ALL_CAPS; any lower case letters will cause bad output.
+.LP
+The bad output will generally be corrected after the next \fB;\fP,
+\fB{\fP, or \fB}\fP.
+.LP
+Some continuation error messages deserve some additional explanation
+.LP
+.TP 4
+.B
+multiple statements continued over multiple lines
+A multi-line statement which is not broken at statement
+boundaries. For example:
+.RS 4
+.HP 4
+if (this_is_a_long_variable == another_variable) a =
+.br
+b + c;
+.LP
+Will trigger this error. Instead, do:
+.HP 8
+if (this_is_a_long_variable == another_variable)
+.br
+a = b + c;
+.RE
+.LP
+.TP 4
+.B
+empty if/for/while body not on its own line
+For visibility, empty bodies for if, for, and while statements should be
+on their own line. For example:
+.RS 4
+.HP 4
+while (do_something(&x) == 0);
+.LP
+Will trigger this error. Instead, do:
+.HP 8
+while (do_something(&x) == 0)
+.br
+;

+
+.SH NAME
+\fBztest\fR \- was written by the ZFS Developers as a ZFS unit test.
+.SH SYNOPSIS
+.LP
+.BI "ztest <options>"
+.SH DESCRIPTION
+.LP
+This manual page documents briefly the \fBztest\fR command.
+.LP
+\fBztest\fR was written by the ZFS Developers as a ZFS unit test. The
+tool was developed in tandem with the ZFS functionality and was
+executed nightly as one of the many regression test against the daily
+build. As features were added to ZFS, unit tests were also added to
+\fBztest\fR. In addition, a separate test development team wrote and
+executed more functional and stress tests.
+.LP
+By default \fBztest\fR runs for ten minutes and uses block files
+(stored in /tmp) to create pools rather than using physical disks.
+Block files afford \fBztest\fR its flexibility to play around with
+zpool components without requiring large hardware configurations.
+However, storing the block files in /tmp may not work for you if you
+have a small tmp directory.
+.LP
+By default is non-verbose. This is why entering the command above will
+result in \fBztest\fR quietly executing for 5 minutes. The -V option
+can be used to increase the verbosity of the tool. Adding multiple -V
+option is allowed and the more you add the more chatty \fBztest\fR
+becomes.
+.LP
+After the \fBztest\fR run completes, you should notice many ztest.*
+files lying around. Once the run completes you can safely remove these
+files. Note that you shouldn't remove these files during a run. You
+can re-use these files in your next \fBztest\fR run by using the -E
+option.

+.LP
+Maybe you'd like to run ztest for longer? To do so simply use the -T
+option and specify the runlength in seconds like so:
+.IP
+ztest -f / -V -T 120
+
+.SH "ENVIRONMENT VARIABLES"
+.TP
+.B "ZFS_STACK_SIZE=stacksize"
+Limit the default stack size to \fBstacksize\fR bytes for the purpose of
+detecting and debugging kernel stack overflows. This value defaults to
+\fB32K\fR which is double the default \fB16K\fR Linux kernel stack size.
+
+In practice, setting the stack size slightly higher is needed because
+differences in stack usage between kernel and user space can lead to spurious
+stack overflows (especially when debugging is enabled). The specified value
+will be rounded up to a floor of PTHREAD_STACK_MIN which is the minimum stack
+required for a NULL procedure in user space.
+
+By default the stack size is limited to 256K.

+.TH vdev_id.conf 5
+.SH NAME
+vdev_id.conf \- Configuration file for vdev_id
+.SH DESCRIPTION
+.I vdev_id.conf
+is the configuration file for
+.BR vdev_id (8).
+It controls the default behavior of
+.BR vdev_id (8)
+while it is mapping a disk device name to an alias.
+.PP
+The
+.I vdev_id.conf
+file uses a simple format consisting of a keyword followed by one or
+more values on a single line. Any line not beginning with a recognized
+keyword is ignored. Comments may optionally begin with a hash
+character.
+
+The following keywords and values are used.
+.TP
+\fIalias\fR <name> <devlink>
+Maps a device link in the /dev directory hierarchy to a new device
+name. The udev rule defining the device link must have run prior to
+.BR vdev_id (8).
+A defined alias takes precedence over a topology-derived name, but the
+two naming methods can otherwise coexist. For example, one might name
+drives in a JBOD with the sas_direct topology while naming an internal
+L2ARC device with an alias.
+
+\fIname\fR - the name of the link to the device that will by created in
+/dev/disk/by-vdev.
+
+\fIdevlink\fR - the name of the device link that has already been
+defined by udev. This may be an absolute path or the base filename.
+
+.TP
+\fIchannel\fR [pci_slot] <port> <name>
+Maps a physical path to a channel name (typically representing a single
+disk enclosure).
+
+\fIpci_slot\fR - specifies the PCI SLOT of the HBA
+hosting the disk enclosure being mapped, as found in the output of
+.BR lspci (8).
+This argument is not used in sas_switch mode.
+
+\fIport\fR - specifies the numeric identifier of the HBA or SAS switch port
+connected to the disk enclosure being mapped.
+
+\fIname\fR - specifies the name of the channel.
+
+.TP
+\fIslot\fR <old> <new> [channel]
+Maps a disk slot number as reported by the operating system to an
+alternative slot number. If the \fIchannel\fR parameter is specified
+then the mapping is only applied to slots in the named channel,
+otherwise the mapping is applied to all channels. The first-specified
+\fIslot\fR rule that can match a slot takes precedence. Therefore a
+channel-specific mapping for a given slot should generally appear before
+a generic mapping for the same slot. In this way a custom mapping may
+be applied to a particular channel and a default mapping applied to the
+others.
+
+.TP
+\fImultipath\fR <yes|no>
+Specifies whether
+.BR vdev_id (8)
+will handle only dm-multipath devices. If set to "yes" then
+.BR vdev_id (8)
+will examine the first running component disk of a dm-multipath
+device as listed by the
+.BR multipath (8)
+command to determine the physical path.
+.TP
+\fItopology\fR <sas_direct|sas_switch>
+Identifies a physical topology that governs how physical paths are
+mapped to channels.
+
+\fIsas_direct\fR - in this mode a channel is uniquely identified by
+a PCI slot and a HBA port number
+
+\fIsas_switch\fR - in this mode a channel is uniquely identified by
+a SAS switch port number
+
+.TP
+\fIphys_per_port\fR <num>
+Specifies the number of PHY devices associated with a SAS HBA port or SAS
+switch port.
+.BR vdev_id (8)
+internally uses this value to determine which HBA or switch port a
+device is connected to. The default is 4.
+
+.TP
+\fIslot\fR <bay|phy|id|lun>
+Specifies from which element of a SAS identifier the slot number is
+taken. The default is bay.
+
+\fIbay\fR - read the slot number from the bay identifier.
+
+\fIphy\fR - read the slot number from the phy identifier.
+
+\fIid\fR - use the scsi id as the slot number.
+
+\fIlun\fR - use the scsi lun as the slot number.

+\fBzfs_free_leak_on_eio\fR (int)
+.ad
+.RS 12n
+If destroy encounters an EIO while reading metadata (e.g. indirect
+blocks), space referenced by the missing metadata can not be freed.
+Normally this causes the background destroy to become "stalled", as
+it is unable to make forward progress. While in this stalled state,
+all remaining space to free from the error-encountering filesystem is
+"temporarily leaked". Set this flag to cause it to ignore the EIO,
+permanently leak the space from indirect blocks that can not be read,
+and continue to free everything else that it can.
+
+The default, "stalling" behavior is useful if the storage partially
+fails (i.e. some but not all i/os fail), and then later recovers. In
+this case, we will be able to continue pool operations while it is
+partially failed, and when it recovers, we can continue to free the
+space, with no leaks. However, note that this case is actually
+fairly rare.
+
+Typically pools either (a) fail completely (but perhaps temporarily,
+e.g. a top-level vdev going offline), or (b) have localized,
+permanent errors (e.g. disk returns the wrong data due to bit flip or
+firmware bug). In case (a), this setting does not matter because the
+pool will be suspended and the sync thread will not be able to make
+forward progress regardless. In case (b), because the error is
+permanent, the best we can do is leak the minimum amount of space,
+which is what setting this flag will do. Therefore, it is reasonable
+for this flag to normally be set, but we chose the more conservative
+approach of not setting it, so that there is no possibility of
+leaking space in the "partial temporary" failure case.

+.SH ZFS I/O SCHEDULER
+ZFS issues I/O operations to leaf vdevs to satisfy and complete I/Os.
+The I/O scheduler determines when and in what order those operations are
+issued. The I/O scheduler divides operations into five I/O classes
+prioritized in the following order: sync read, sync write, async read,
+async write, and scrub/resilver. Each queue defines the minimum and
+maximum number of concurrent operations that may be issued to the
+device. In addition, the device has an aggregate maximum,
+\fBzfs_vdev_max_active\fR. Note that the sum of the per-queue minimums
+must not exceed the aggregate maximum. If the sum of the per-queue
+maximums exceeds the aggregate maximum, then the number of active I/Os
+may reach \fBzfs_vdev_max_active\fR, in which case no further I/Os will
+be issued regardless of whether all per-queue minimums have been met.
+.sp
+For many physical devices, throughput increases with the number of
+concurrent operations, but latency typically suffers. Further, physical
+devices typically have a limit at which more concurrent operations have no
+effect on throughput or can actually cause it to decrease.
+.sp
+The scheduler selects the next operation to issue by first looking for an
+I/O class whose minimum has not been satisfied. Once all are satisfied and
+the aggregate maximum has not been hit, the scheduler looks for classes
+whose maximum has not been satisfied. Iteration through the I/O classes is
+done in the order specified above. No further operations are issued if the
+aggregate maximum number of concurrent operations has been hit or if there
+are no operations queued for an I/O class that has not hit its maximum.
+Every time an I/O is queued or an operation completes, the I/O scheduler
+looks for new operations to issue.
+.sp
+In general, smaller max_active's will lead to lower latency of synchronous
+operations. Larger max_active's may lead to higher overall throughput,
+depending on underlying storage.
+.sp
+The ratio of the queues' max_actives determines the balance of performance
+between reads, writes, and scrubs. E.g., increasing
+\fBzfs_vdev_scrub_max_active\fR will cause the scrub or resilver to complete
+more quickly, but reads and writes to have higher latency and lower throughput.
+.sp
+All I/O classes have a fixed maximum number of outstanding operations
+except for the async write class. Asynchronous writes represent the data
+that is committed to stable storage during the syncing stage for
+transaction groups. Transaction groups enter the syncing state
+periodically so the number of queued async writes will quickly burst up
+and then bleed down to zero. Rather than servicing them as quickly as
+possible, the I/O scheduler changes the maximum number of active async
+write I/Os according to the amount of dirty data in the pool. Since
+both throughput and latency typically increase with the number of
+concurrent operations issued to physical devices, reducing the
+burstiness in the number of concurrent operations also stabilizes the
+response time of operations from other -- and in particular synchronous
+-- queues. In broad strokes, the I/O scheduler will issue more
+concurrent operations from the async write queue as there's more dirty
+data in the pool.
+.sp
+Async Writes
+.sp
+The number of concurrent operations issued for the async write I/O class
+follows a piece-wise linear function defined by a few adjustable points.
+.nf
+
+ | o---------| <-- zfs_vdev_async_write_max_active
+ ^ | /^ |
+ | | / | |
+active | / | |
+ I/O | / | |
+count | / | |

+ | |
+ | `-- zfs_vdev_async_write_active_max_dirty_percent
+ `--------- zfs_vdev_async_write_active_min_dirty_percent
+
+.fi
+Until the amount of dirty data exceeds a minimum percentage of the dirty
+data allowed in the pool, the I/O scheduler will limit the number of
+concurrent operations to the minimum. As that threshold is crossed, the
+number of concurrent operations issued increases linearly to the maximum at
+the specified maximum percentage of the dirty data allowed in the pool.
+.sp
+Ideally, the amount of dirty data on a busy pool will stay in the sloped
+part of the function between \fBzfs_vdev_async_write_active_min_dirty_percent\fR
+and \fBzfs_vdev_async_write_active_max_dirty_percent\fR. If it exceeds the
+maximum percentage, this indicates that the rate of incoming data is
+greater than the rate that the backend storage can handle. In this case, we
+must further throttle incoming writes, as described in the next section.
+
+.SH ZFS TRANSACTION DELAY
+We delay transactions when we've determined that the backend storage
+isn't able to accommodate the rate of incoming writes.
+.sp
+If there is already a transaction waiting, we delay relative to when
+that transaction will finish waiting. This way the calculated delay time
+is independent of the number of threads concurrently executing
+transactions.
+.sp
+If we are the only waiter, wait relative to when the transaction
+started, rather than the current time. This credits the transaction for
+"time already served", e.g. reading indirect blocks.
+.sp
+The minimum time for a transaction to take is calculated as:
+.nf
+ min_time = zfs_delay_scale * (dirty - min) / (max - dirty)
+ min_time is then capped at 100 milliseconds.
+.fi
+.sp
+The delay has two degrees of freedom that can be adjusted via tunables. The
+percentage of dirty data at which we start to delay is defined by
+\fBzfs_delay_min_dirty_percent\fR. This should typically be at or above
+\fBzfs_vdev_async_write_active_max_dirty_percent\fR so that we only start to
+delay after writing at full speed has failed to keep up with the incoming write
+rate. The scale of the curve is defined by \fBzfs_delay_scale\fR. Roughly speaking,
+this variable determines the amount of delay at the midpoint of the curve.
+.sp

+.fi
+.sp
+Note that since the delay is added to the outstanding time remaining on the
+most recent transaction, the delay is effectively the inverse of IOPS.
+Here the midpoint of 500us translates to 2000 IOPS. The shape of the curve
+was chosen such that small changes in the amount of accumulated dirty data
+in the first 3/4 of the curve yield relatively small differences in the
+amount of delay.
+.sp
+The effects can be easier to understand when the amount of delay is
+represented on a log scale:
+.sp
+.nf

+ + +
+ +--------------------------------------------------------------+
+ 0% <- zfs_dirty_data_max -> 100%
+.fi
+.sp
+Note here that only as the amount of dirty data approaches its limit does
+the delay start to increase rapidly. The goal of a properly tuned system
+should be to keep the amount of dirty data out of that range by first
+ensuring that the appropriate limits are set for the I/O scheduler to reach
+optimal throughput on the backend storage, and then by changing the value
+of \fBzfs_delay_scale\fR to increase the steepness of the curve.

+.TH ZPOOL-FEATURES 5 "Aug 27, 2013"
+.SH NAME
+zpool\-features \- ZFS pool feature descriptions
+.SH DESCRIPTION
+.sp
+.LP
+ZFS pool on\-disk format versions are specified via "features" which replace
+the old on\-disk format numbers (the last supported on\-disk format number is
+28). To enable a feature on a pool use the \fBupgrade\fR subcommand of the
+\fBzpool\fR(8) command, or set the \fBfeature@\fR\fIfeature_name\fR property
+to \fBenabled\fR.
+.sp
+.LP
+The pool format does not affect file system version compatibility or the ability
+to send file systems between pools.
+.sp
+.LP
+Since most features can be enabled independently of each other the on\-disk
+format of the pool is specified by the set of all features marked as
+\fBactive\fR on the pool. If the pool was created by another software version
+this set may include unsupported features.
+.SS "Identifying features"
+.sp
+.LP
+Every feature has a guid of the form \fIcom.example:feature_name\fR. The reverse
+DNS name ensures that the feature's guid is unique across all ZFS
+implementations. When unsupported features are encountered on a pool they will
+be identified by their guids. Refer to the documentation for the ZFS
+implementation that created the pool for information about those features.
+.sp
+.LP
+Each supported feature also has a short name. By convention a feature's short
+name is the portion of its guid which follows the ':' (e.g.
+\fIcom.example:feature_name\fR would have the short name \fIfeature_name\fR),
+however a feature's short name may differ across ZFS implementations if
+following the convention would result in name conflicts.
+.SS "Feature states"
+.sp
+.LP
+Features can be in one of three states:
+.sp
+.ne 2
+.na
+\fB\fBactive\fR\fR
+.ad
+.RS 12n
+This feature's on\-disk format changes are in effect on the pool. Support for
+this feature is required to import the pool in read\-write mode. If this
+feature is not read-only compatible, support is also required to import the pool
+in read\-only mode (see "Read\-only compatibility").
+.RE
+
+.sp
+.ne 2
+.na
+\fB\fBenabled\fR\fR
+.ad
+.RS 12n
+An administrator has marked this feature as enabled on the pool, but the
+feature's on\-disk format changes have not been made yet. The pool can still be
+imported by software that does not support this feature, but changes may be made
+to the on\-disk format at any time which will move the feature to the
+\fBactive\fR state. Some features may support returning to the \fBenabled\fR
+state after becoming \fBactive\fR. See feature\-specific documentation for
+details.
+.RE
+
+.sp
+.ne 2
+.na
+\fBdisabled\fR
+.ad
+.RS 12n
+This feature's on\-disk format changes have not been made and will not be made
+unless an administrator moves the feature to the \fBenabled\fR state. Features
+cannot be disabled once they have been enabled.
+.RE
+
+.sp
+.LP
+The state of supported features is exposed through pool properties of the form
+\fIfeature@short_name\fR.
+.SS "Read\-only compatibility"
+.sp
+.LP
+Some features may make on\-disk format changes that do not interfere with other
+software's ability to read from the pool. These features are referred to as
+"read\-only compatible". If all unsupported features on a pool are read\-only
+compatible, the pool can be imported in read\-only mode by setting the
+\fBreadonly\fR property during import (see \fBzpool\fR(8) for details on
+importing pools).
+.SS "Unsupported features"
+.sp
+.LP
+For each unsupported feature enabled on an imported pool a pool property
+named \fIunsupported@feature_guid\fR will indicate why the import was allowed
+despite the unsupported feature. Possible values for this property are:
+
+.sp
+.ne 2
+.na
+\fB\fBinactive\fR\fR
+.ad
+.RS 12n
+The feature is in the \fBenabled\fR state and therefore the pool's on\-disk
+format is still compatible with software that does not support this feature.
+.RE
+
+.sp
+.ne 2
+.na
+\fB\fBreadonly\fR\fR
+.ad
+.RS 12n
+The feature is read\-only compatible and the pool has been imported in
+read\-only mode.
+.RE
+
+.SS "Feature dependencies"
+.sp
+.LP
+Some features depend on other features being enabled in order to function
+properly. Enabling a feature will automatically enable any features it
+depends on.
+.SH FEATURES
+.sp
+.LP
+The following features are supported on this system:
+.sp
+.ne 2
+.na
+\fB\fBasync_destroy\fR\fR
+.ad
+.RS 4n
+.TS
+l l .
+GUID com.delphix:async_destroy
+READ\-ONLY COMPATIBLE yes
+DEPENDENCIES none
+.TE
+
+Destroying a file system requires traversing all of its data in order to
+return its used space to the pool. Without \fBasync_destroy\fR the file system
+is not fully removed until all space has been reclaimed. If the destroy
+operation is interrupted by a reboot or power outage the next attempt to open
+the pool will need to complete the destroy operation synchronously.
+
+When \fBasync_destroy\fR is enabled the file system's data will be reclaimed
+by a background process, allowing the destroy operation to complete without
+traversing the entire file system. The background process is able to resume
+interrupted destroys after the pool has been opened, eliminating the need
+to finish interrupted destroys as part of the open operation. The amount
+of space remaining to be reclaimed by the background process is available
+through the \fBfreeing\fR property.
+
+This feature is only \fBactive\fR while \fBfreeing\fR is non\-zero.

+DEPENDENCIES none
+.TE
+
+This feature increases the performance of creating and using a large
+number of snapshots of a single filesystem or volume, and also reduces
+the disk space required.
+
+When there are many snapshots, each snapshot uses many Block Pointer
+Objects (bpobj's) to track blocks associated with that snapshot.
+However, in common use cases, most of these bpobj's are empty. This
+feature allows us to create each bpobj on-demand, thus eliminating the
+empty bpobjs.
+
+This feature is \fBactive\fR while there are any filesystems, volumes,
+or snapshots which were created after enabling this feature.

+
+This feature enables filesystem and snapshot limits. These limits can be used
+to control how many filesystems and/or snapshots can be created at the point in
+the tree on which the limits are set.

+set on a dataset. Once activated the feature is never deactivated.

+DEPENDENCIES none
+.TE
+
+\fBlz4\fR is a high-performance real-time compression algorithm that
+features significantly faster compression and decompression as well as a
+higher compression ratio than the older \fBlzjb\fR compression.
+Typically, \fBlz4\fR compression is approximately 50% faster on
+compressible data and 200% faster on incompressible data than
+\fBlzjb\fR. It is also approximately 80% faster on decompression, while
+giving approximately 10% better compression ratio.
+
+When the \fBlz4_compress\fR feature is set to \fBenabled\fR, the
+administrator can turn on \fBlz4\fR compression on any dataset on the
+pool using the \fBzfs\fR(8) command. Please note that doing so will
+immediately activate the \fBlz4_compress\fR feature on the underlying
+pool using the \fBzfs\fR(1M) command. Also, all newly written metadata
+will be compressed with \fBlz4\fR algorithm. Since this feature is not
+read-only compatible, this operation will render the pool unimportable
+on systems without support for the \fBlz4_compress\fR feature. Booting
+off of \fBlz4\fR-compressed root pools is supported.
+
+This feature becomes \fBactive\fR as soon as it is enabled and will
+never return to being \fBenabled\fB.

+is organized within the pool. If this feature is \fBenabled\fR, ZFS will
+set this feature to \fBactive\fR when a new space map object is created or

+DEPENDENCIES enabled_txg
+.TE
+
+This feature improves performance of incremental sends ("zfs send -i")
+and receives for objects with many holes. The most common case of
+hole-filled objects is zvols.
+
+An incremental send stream from snapshot \fBA\fR to snapshot \fBB\fR
+contains information about every block that changed between \fBA\fR and
+\fBB\fR. Blocks which did not change between those snapshots can be
+identified and omitted from the stream using a piece of metadata called
+the 'block birth time', but birth times are not recorded for holes (blocks
+filled only with zeroes). Since holes created after \fBA\fR cannot be
+distinguished from holes created before \fBA\fR, information about every
+hole in the entire filesystem or zvol is included in the send stream.
+
+For workloads where holes are rare this is not a problem. However, when
+incrementally replicating filesystems or zvols with many holes (for
+example a zvol formatted with another filesystem) a lot of time will
+be spent sending and receiving unnecessary information about holes that
+already exist on the receiving side.
+
+Once the \fBhole_birth\fR feature has been enabled the block birth times
+of all new holes will be recorded. Incremental sends between snapshots
+created after this feature is enabled will use this new metadata to avoid
+sending information about holes that already exist on the receiving side.

+finalist in the NIST SHA-3 competition. It provides a very high security
+margin and high performance on 64-bit hardware (80% faster than

+
+.SH SYNOPSIS
+.LP
+.BI "fsck.zfs [" "options" "] <" "dataset" ">"
+
+.SH DESCRIPTION
+.LP
+\fBfsck.zfs\fR is a shell stub that does nothing and always returns
+true. It is installed by ZoL because some Linux distributions expect
+a fsck helper for all filesystems.
+
+.SH OPTIONS
+.HP
+All \fIoptions\fR and the \fIdataset\fR are ignored.
+
+.SH "NOTES"
+.LP
+ZFS datasets are checked by running \fBzpool scrub\fR on the
+containing pool. An individual ZFS dataset is never checked
+independently of its pool, which is unlike a regular filesystem.
+
+.SH "BUGS"
+.LP
+On some systems, if the \fIdataset\fR is in a degraded pool, then it
+might be appropriate for \fBfsck.zfs\fR to return exit code 4 to
+indicate an uncorrected filesystem error.
+.LP
+Similarly, if the \fIdataset\fR is in a faulted pool and has a legacy
+/etc/fstab record, then \fBfsck.zfs\fR should return exit code 8 to
+indicate a fatal operational error.

+
+.SH NAME
+mount.zfs \- mount a ZFS filesystem
+.SH SYNOPSIS
+.LP
+.BI "mount.zfs [\-sfnvh] [\-o " options "]" " dataset mountpoint
+
+.SH DESCRIPTION
+.BR mount.zfs
+is part of the zfsutils package for Linux. It is a helper program that
+is usually invoked by the
+.BR mount (8)
+or
+.BR zfs (8)
+commands to mount a ZFS dataset.
+
+All
+.I options
+are handled according to the FILESYSTEM INDEPENDENT MOUNT OPTIONS
+section in the
+.BR mount (8)
+manual, except for those described below.
+
+The
+.I dataset
+parameter is a ZFS filesystem name, as output by the
+.B "zfs list -H -o name
+command. This parameter never has a leading slash character and is
+not a device name.
+
+The
+.I mountpoint
+parameter is the path name of a directory.
+
+
+.SH OPTIONS
+.TP
+.BI "\-s"
+Ignore bad or sloppy mount options.
+.TP
+.BI "\-f"
+Do a fake mount; do not perform the mount operation.
+.TP
+.BI "\-n"
+Do not update the /etc/mtab file.
+.TP
+.BI "\-v"
+Increase verbosity.
+.TP
+.BI "\-h"
+Print the usage message.
+.TP
+.BI "\-o context"
+This flag sets the SELinux context for all files in the filesystem
+under that mountpoint.
+.TP
+.BI "\-o fscontext"
+This flag sets the SELinux context for the filesystem being mounted.
+.TP
+.BI "\-o defcontext"
+This flag sets the SELinux context for unlabeled files.
+.TP
+.BI "\-o rootcontext"
+This flag sets the SELinux context for the root inode of the filesystem.
+.TP
+.BI "\-o legacy"
+This private flag indicates that the
+.I dataset
+has an entry in the /etc/fstab file.
+.TP
+.BI "\-o noxattr"
+This private flag disables extended attributes.
+.TP
+.BI "\-o xattr
+This private flag enables directory-based extended attributes and, if
+appropriate, adds a ZFS context to the selinux system policy.
+.TP
+.BI "\-o saxattr
+This private flag enables system attributed-based extended attributes and, if
+appropriate, adds a ZFS context to the selinux system policy.
+.TP
+.BI "\-o dirxattr
+Equivalent to
+.BR xattr .
+.TP
+.BI "\-o zfsutil"
+This private flag indicates that
+.BR mount (8)
+is being called by the
+.BR zfs (8)
+command.
+
+.SH NOTES
+ZFS conventionally requires that the
+.I mountpoint
+be an empty directory, but the Linux implementation inconsistently
+enforces the requirement.
+
+The
+.BR mount.zfs
+helper does not mount the contents of zvols.
+
+.SH FILES
+.TP 18n
+.I /etc/fstab
+The static filesystem table.
+.TP
+.I /etc/mtab
+The mounted filesystem table.
+.SH "AUTHORS"

+.SH NAME
+vdev_id \- generate user-friendly names for JBOD disks
+.SH SYNOPSIS
+.LP
+.nf
+\fBvdev_id\fR <-d dev> [-c config_file] [-g sas_direct|sas_switch]
+ [-m] [-p phys_per_port]
+\fBvdev_id\fR -h
+.fi
+.SH DESCRIPTION
+The \fBvdev_id\fR command is a udev helper which parses the file
+.BR /etc/zfs/vdev_id.conf (5)
+to map a physical path in a storage topology to a channel name. The
+channel name is combined with a disk enclosure slot number to create an
+alias that reflects the physical location of the drive. This is
+particularly helpful when it comes to tasks like replacing failed
+drives. Slot numbers may also be re-mapped in case the default
+numbering is unsatisfactory. The drive aliases will be created as
+symbolic links in /dev/disk/by-vdev.
+
+The currently supported topologies are sas_direct and sas_switch. A
+multipath mode is supported in which dm-mpath devices are handled by
+examining the first-listed running component disk as reported by the
+.BR multipath (8)
+command. In multipath mode the configuration file should contain a
+channel definition with the same name for each path to a given
+enclosure.
+
+.BR vdev_id
+also supports creating aliases based on existing udev links in the /dev
+hierarchy using the \fIalias\fR configuration file keyword. See the
+.BR vdev_id.conf (5)
+man page for details.
+
+.SH OPTIONS
+.TP
+\fB\-c\fR <config_file>
+Specifies the path to an alternate configuration file. The default is
+/etc/zfs/vdev_id.conf.
+.TP
+\fB\-d\fR <device>
+This is the only mandatory argument. Specifies the name of a device
+in /dev, i.e. "sda".
+.TP
+\fB\-g\fR <sas_direct|sas_switch>
+Identifies a physical topology that governs how physical paths are
+mapped to channels.
+
+\fIsas_direct\fR - in this mode a channel is uniquely identified by
+a PCI slot and a HBA port number
+
+\fIsas_switch\fR - in this mode a channel is uniquely identified by
+a SAS switch port number
+.TP
+\fB\-m\fR
+Specifies that
+.BR vdev_id (8)
+will handle only dm-multipath devices. If set to "yes" then
+.BR vdev_id (8)
+will examine the first running component disk of a dm-multipath
+device as listed by the
+.BR multipath (8)
+command to determine the physical path.
+.TP
+\fB\-p\fR <phys_per_port>
+Specifies the number of PHY devices associated with a SAS HBA port or SAS
+switch port.
+.BR vdev_id (8)
+internally uses this value to determine which HBA or switch port a
+device is connected to. The default is 4.
+.TP

+Print a usage summary.

+
+.SH "DESCRIPTION"
+The \fBzdb\fR utility displays information about a ZFS pool useful for
+debugging and performs some amount of consistency checking. It is a not a
+general purpose tool and options (and facilities) may change. This is neither
+a fsck(8) nor an fsdb(8) utility.
+
+.P
+The output of this command in general reflects the on-disk structure of a ZFS
+pool, and is inherently unstable. The precise output of most invocations is
+not documented, a knowledge of ZFS internals is assumed.
+
+.P
+If the \fIdataset\fR argument does not contain any \fB/\fR or \fB@\fR
+characters, it is interpreted as a pool name. The root dataset can be
+specified as \fIpool\fB/\fR (pool name followed by a slash).
+
+.P
+When operating on an imported and active pool it is possible, though unlikely,
+that zdb may interpret inconsistent pool data and behave erratically.

+.SH ZEVENTS
+.PP
+A zevent is comprised of a list of nvpairs (name/value pairs). Each zevent
+contains an EID (Event IDentifier) that uniquely identifies it throughout
+the lifetime of the loaded ZFS kernel module; this EID is a monotonically
+increasing integer that resets to 1 each time the kernel module is loaded.
+Each zevent also contains a class string that identifies the type of event.
+For brevity, a subclass string is defined that omits the leading components
+of the class string. Additional nvpairs exist to provide event details.
+.PP
+The kernel maintains a list of recent zevents that can be viewed (along with
+their associated lists of nvpairs) using the "\fBzpool events \-v\fR" command.
+
+.SH CONFIGURATION
+.PP
+ZEDLETs to be invoked in response to zevents are located in the
+\fIenabled-zedlets\fR directory. These can be symlinked or copied from the
+\fIinstalled-zedlets\fR directory; symlinks allow for automatic updates
+from the installed ZEDLETs, whereas copies preserve local modifications.
+As a security measure, ZEDLETs must be owned by root. They must have
+execute permissions for the user, but they must not have write permissions
+for group or other. Dotfiles are ignored.
+.PP
+ZEDLETs are named after the zevent class for which they should be invoked.
+In particular, a ZEDLET will be invoked for a given zevent if either its
+class or subclass string is a prefix of its filename (and is followed by
+a non-alphabetic character). As a special case, the prefix "all" matches
+all zevents. Multiple ZEDLETs may be invoked for a given zevent.
+
+.SH ZEDLETS
+.PP
+ZEDLETs are executables invoked by the ZED in response to a given zevent.
+They should be written under the presumption they can be invoked concurrently,
+and they should use appropriate locking to access any shared resources.
+Common variables used by ZEDLETs can be stored in the default rc file which
+is sourced by scripts; these variables should be prefixed with "ZED_".
+.PP
+The zevent nvpairs are passed to ZEDLETs as environment variables.
+Each nvpair name is converted to an environment variable in the following
+manner: 1) it is prefixed with "ZEVENT_", 2) it is converted to uppercase,
+and 3) each non-alphanumeric character is converted to an underscore.
+Some additional environment variables have been defined to present certain
+nvpair values in a more convenient form. An incomplete list of zevent
+environment variables is as follows:
+.TP
+.B
+ZEVENT_EID
+The Event IDentifier.
+.TP
+.B
+ZEVENT_CLASS
+The zevent class string.
+.TP
+.B
+ZEVENT_SUBCLASS
+The zevent subclass string.
+.TP
+.B
+ZEVENT_TIME
+The time at which the zevent was posted as
+"\fIseconds\fR\ \fInanoseconds\fR" since the Epoch.
+.TP
+.B
+ZEVENT_TIME_SECS
+The \fIseconds\fR component of ZEVENT_TIME.
+.TP
+.B
+ZEVENT_TIME_NSECS
+The \fInanoseconds\fR component of ZEVENT_TIME.
+.TP
+.B
+ZEVENT_TIME_STRING
+An almost-RFC3339-compliant string for ZEVENT_TIME.
+.PP
+Additionally, the following ZED & ZFS variables are defined:
+.TP
+.B
+ZED_PID
+The daemon's process ID.
+.TP
+.B
+ZED_ZEDLET_DIR
+The daemon's current \fIenabled-zedlets\fR directory.
+.TP
+.B
+ZFS_ALIAS
+The ZFS alias (\fIname-version-release\fR) string used to build the daemon.
+.TP
+.B
+ZFS_VERSION
+The ZFS version used to build the daemon.
+.TP
+.B
+ZFS_RELEASE
+The ZFS release used to build the daemon.
+.PP
+ZEDLETs may need to call other ZFS commands. The installation paths of
+the following executables are defined: \fBZDB\fR, \fBZED\fR, \fBZFS\fR,
+\fBZINJECT\fR, and \fBZPOOL\fR. These variables can be overridden in the
+rc file if needed.

+
+.SH BUGS
+.PP
+Events are processed synchronously by a single thread. This can delay the
+processing of simultaneous zevents.
+.PP
+There is no maximum timeout for ZEDLET execution. Consequently, a misbehaving
+ZEDLET can delay the processing of subsequent zevents.
+.PP
+The ownership and permissions of the \fIenabled-zedlets\fR directory (along
+with all parent directories) are not checked. If any of these directories
+are improperly owned or permissioned, an unprivileged user could insert a
+ZEDLET to be executed as root. The requirement that ZEDLETs be owned by
+root mitigates this to some extent.
+.PP
+ZEDLETs are unable to return state/status information to the kernel.
+.PP
+Some zevent nvpair types are not handled. These are denoted by zevent
+environment variables having a "_NOT_IMPLEMENTED_" value.

+.SH DESCRIPTION
+.LP
+The \fBzfs\fR command configures \fBZFS\fR datasets within a \fBZFS\fR storage pool, as described in \fBzpool\fR(8). A dataset is identified by a unique path within the \fBZFS\fR namespace. For example:
+.sp
+.in +2
+.nf
+pool/{filesystem,volume,snapshot}
+.fi
+.in -2
+.sp
+

+.LP
+where the maximum length of a dataset name is \fBMAXNAMELEN\fR (256 bytes).
+.sp
+.LP
+A dataset can be one of the following:

+
+.SS "ZFS File System Hierarchy"
+.LP
+A \fBZFS\fR storage pool is a logical collection of devices that provide space for datasets. A storage pool is also the root of the \fBZFS\fR file system hierarchy.
+.sp
+.LP
+The root of the pool can be accessed as a file system, such as mounting and unmounting, taking snapshots, and setting properties. The physical storage characteristics, however, are managed by the \fBzpool\fR(8) command.
+.sp
+.LP
+See \fBzpool\fR(8) for more information on creating and administering pools.
+.SS "Snapshots"
+.LP
+A snapshot is a read-only copy of a file system or volume. Snapshots can be created extremely quickly, and initially consume no additional space within the pool. As data within the active dataset changes, the snapshot consumes more data than would otherwise be shared with the active dataset.
+.sp
+.LP
+Snapshots can have arbitrary names. Snapshots of volumes can be cloned or rolled back. Visibility is determined by the \fBsnapdev\fR property of the parent volume.
+.sp
+.LP
+File system snapshots can be accessed under the \fB\&.zfs/snapshot\fR directory in the root of the file system. Snapshots are automatically mounted on demand and may be unmounted at regular intervals. The visibility of the \fB\&.zfs\fR directory can be controlled by the \fBsnapdir\fR property.
+.SS "Bookmarks"
+.LP
+A bookmark is like a snapshot, a read-only copy of a file system or volume. Bookmarks can be created extremely quickly, compared to snapshots, and they consume no additional space within the pool. Bookmarks can also have arbitrary names, much like snapshots.
+.sp
+.LP
+Unlike snapshots, bookmarks can not be accessed through the filesystem in any way. From a storage standpoint a bookmark just provides a way to reference when a snapshot was created as a distinct object. Bookmarks are initially tied to a snapshot, not the filesystem/volume, and they will survive if the snapshot itself is destroyed. Since they are very light weight there's little incentive to destroy them.
+.SS "Clones"
+.LP
+A clone is a writable volume or file system whose initial contents are the same as another dataset. As with snapshots, creating a clone is nearly instantaneous, and initially consumes no additional space.
+.sp
+.LP
+Clones can only be created from a snapshot. When a snapshot is cloned, it creates an implicit dependency between the parent and child. Even though the clone is created somewhere else in the dataset hierarchy, the original snapshot cannot be destroyed as long as a clone exists. The \fBorigin\fR property exposes this dependency, and the \fBdestroy\fR command lists any such dependencies, if they exist.
+.sp
+.LP
+The clone parent-child dependency relationship can be reversed by using the \fBpromote\fR subcommand. This causes the "origin" file system to become a clone of the specified file system, which makes it possible to destroy the file system that the clone was created from.
+.SS "Mount Points"
+.LP
+Creating a \fBZFS\fR file system is a simple operation, so the number of file systems per system is likely to be numerous. To cope with this, \fBZFS\fR automatically manages mounting and unmounting file systems without the need to edit the \fB/etc/fstab\fR file. All automatically managed file systems are mounted by \fBZFS\fR at boot time.
+.sp
+.LP
+By default, file systems are mounted under \fB/\fIpath\fR\fR, where \fIpath\fR is the name of the file system in the \fBZFS\fR namespace. Directories are created and destroyed as needed.
+.sp
+.LP
+A file system can also have a mount point set in the \fBmountpoint\fR property. This directory is created as needed, and \fBZFS\fR automatically mounts the file system when the \fBzfs mount -a\fR command is invoked (without editing \fB/etc/fstab\fR). The \fBmountpoint\fR property can be inherited, so if \fBpool/home\fR has a mount point of \fB/export/stuff\fR, then \fBpool/home/user\fR automatically inherits a mount point of \fB/export/stuff/user\fR.
+.sp
+.LP
+A file system \fBmountpoint\fR property of \fBnone\fR prevents the file system from being mounted.
+.sp
+.LP
+If needed, \fBZFS\fR file systems can also be managed with traditional tools (\fBmount\fR, \fBumount\fR, \fB/etc/fstab\fR). If a file system's mount point is set to \fBlegacy\fR, \fBZFS\fR makes no attempt to manage the file system, and the administrator is responsible for mounting and unmounting the file system.
+.SS "Deduplication"
+.LP
+Deduplication is the process for removing redundant data at the block-level, reducing the total amount of data stored. If a file system has the \fBdedup\fR property enabled, duplicate data blocks are removed synchronously. The result is that only unique data is stored and common components are shared among files.
+.sp
+\fBWARNING: DO NOT ENABLE DEDUPLICATION UNLESS YOU NEED IT AND KNOW EXACTLY WHAT YOU ARE DOING!\fR
+.sp
+Deduplicating data is a very resource-intensive operation. It is generally recommended that you have \fIat least\fR 1.25 GiB of RAM per 1 TiB of storage when you enable deduplication. But calculating the exact requirements is a somewhat complicated affair.
+.sp
+Enabling deduplication on an improperly-designed system will result in extreme performance issues (extremely slow filesystem and snapshot deletions etc.) and can potentially lead to data loss (i.e. unimportable pool due to memory exhaustion) if your system is not built for this purpose. Deduplication affects the processing power (CPU), disks (and the controller) as well as primary (real) memory.
+.sp
+Before creating a pool with deduplication enabled, ensure that you have planned your hardware requirements appropriately and implemented appropriate recovery practices, such as regular backups.
+.sp
+Unless necessary, deduplication should NOT be enabled on a system. Instead, consider using \fIcompression=lz4\fR, as a less resource-intensive alternative.
+.SS "Properties"
+.sp
+.LP
+Properties are divided into two types: native properties and user-defined (or "user") properties. Native properties either export internal statistics or control \fBZFS\fR behavior. User properties have no effect on \fBZFS\fR behavior, but you can use them to annotate datasets and snapshots in a way that is meaningful in your environment.
+.sp
+.LP
+Properties are generally inherited from the parent unless overridden by the child. See the documentation below for exceptions.
+.sp
+.LP
+.SS "Native Properties"
+Native properties apply to all dataset types unless otherwise noted. However, native properties cannot be edited on snapshots.
+.sp
+.LP
+The values of numeric native properties can be specified using human-readable abbreviations (\fBK\fR, \fBM\fR, \fBG\fR, \fBT\fR, \fBP\fR, \fBE\fR, and \fBZ\fR). These abbreviations can optionally use the IEC binary prefixes (e.g. GiB) or SI decimal prefixes (e.g. GB), though the SI prefixes are treated as binary prefixes. Abbreviations are case-insensitive. The following are all valid (and equal) specifications:
+.sp
+.in +2
+.nf
+1536M, 1.5g, 1.50GB, 1.5GiB
+.fi
+.in -2
+.sp
+
+.sp
+.LP
+The values of non-numeric native properties are case-sensitive and must be lowercase, except for \fBmountpoint\fR, \fBsharenfs\fR, and \fBsharesmb\fR.
+.sp
+.LP
+The following native properties consist of read-only statistics about the dataset. These properties can be neither set, nor inherited.

+.SS "Temporary Mount Point Properties"
+.LP
+When a file system is mounted, either through \fBmount\fR(8) for legacy mounts or the \fBzfs mount\fR command for normal file systems, its mount options are set according to its properties. The correlation between properties and mount options is as follows:
+.sp
+.in +2
+.nf
+ PROPERTY MOUNT OPTION
+ atime atime/noatime
+ canmount auto/noauto
+ devices devices/nodevices
+ exec exec/noexec
+ readonly ro/rw
+ relatime relatime/norelatime
+ setuid suid/nosuid
+ xattr xattr/noxattr
+ nbmand nbmand/nonbmand (Solaris)
+.fi
+.in -2
+.sp
+
+.sp
+.LP
+In addition, these options can be set on a per-mount basis using the \fB-o\fR option, without affecting the property that is stored on disk. The values specified on the command line override the values stored in the dataset. The \fB-nosuid\fR option is an alias for \fBnodevices,nosetuid\fR. These properties are reported as "temporary" by the \fBzfs get\fR command. If the properties are changed while the dataset is mounted, the new setting overrides any temporary settings.
+.SS "User Properties"
+.LP
+In addition to the standard native properties, \fBZFS\fR supports arbitrary user properties. User properties have no effect on \fBZFS\fR behavior, but applications or administrators can use them to annotate datasets (file systems, volumes, and snapshots). Unlike native properties, user properties are editable on snapshots.
+.sp
+.LP
+User property names must contain a colon (\fB:\fR) character to distinguish them from native properties. They may contain lowercase letters, numbers, and the following punctuation characters: colon (\fB:\fR), dash (\fB-\fR), period (\fB\&.\fR), and underscore (\fB_\fR). The expected convention is that the property name is divided into two portions such as \fImodule\fR\fB:\fR\fIproperty\fR, but this namespace is not enforced by \fBZFS\fR. User property names can be at most 256 characters, and cannot begin with a dash (\fB-\fR).
+.sp
+.LP
+When making programmatic use of user properties, it is strongly suggested to use a reversed \fBDNS\fR domain name for the \fImodule\fR component of property names to reduce the chance that two independently-developed packages use the same property name for different purposes. For example, property names beginning with \fBcom.sun\fR. are reserved for definition by Oracle Corporation (which acquired Sun Microsystems).
+.sp
+.LP
+The values of user properties are arbitrary strings, are always inherited, and are never validated. All of the commands that operate on properties (\fBzfs list\fR, \fBzfs get\fR, \fBzfs set\fR, and so forth) can be used to manipulate both native properties and user properties. Use the \fBzfs inherit\fR command to clear a user property. If the property is not defined in any parent dataset, it is removed entirely. Property values are limited to 1024 characters.
+.SS "ZFS Volumes as Swap"
+.LP
+\fBZFS\fR volumes may be used as Linux swap devices. After creating the volume
+with the \fBzfs create\fR command set up and enable the swap area using the

+.SH NAME
+zinject \- ZFS Fault Injector
+.SH DESCRIPTION
+.BR zinject
+creates artificial problems in a ZFS pool by simulating data corruption or device failures. This program is dangerous.
+.SH SYNOPSIS
+.TP
+.B "zinject"
+List injection records.
+.TP
+.B "zinject \-b \fIobjset:object:level:blkd\fB [\-f \fIfrequency\fB] [\-amu] \fIpool\fB"
+Force an error into the pool at a bookmark.
+.TP
+.B "zinject \-c <\fIid\fB | all>
+Cancel injection records.
+.TP
+.B "zinject \-d \fIvdev\fB \-A <degrade|fault> \fIpool\fB
+Force a vdev into the DEGRADED or FAULTED state.
+.TP
+.B "zinject -d \fIvdev\fB -D latency:lanes \fIpool\fB
+
+Add an artificial delay to IO requests on a particular
+device, such that the requests take a minimum of 'latency'
+milliseconds to complete. Each delay has an associated
+number of 'lanes' which defines the number of concurrent
+IO requests that can be processed.
+
+For example, with a single lane delay of 10 ms (-D 10:1),
+the device will only be able to service a single IO request
+at a time with each request taking 10 ms to complete. So,
+if only a single request is submitted every 10 ms, the
+average latency will be 10 ms; but if more than one request
+is submitted every 10 ms, the average latency will be more
+than 10 ms.
+
+Similarly, if a delay of 10 ms is specified to have two
+lanes (-D 10:2), then the device will be able to service
+two requests at a time, each with a minimum latency of
+10 ms. So, if two requests are submitted every 10 ms, then
+the average latency will be 10 ms; but if more than two
+requests are submitted every 10 ms, the average latency
+will be more than 10 ms.
+
+Also note, these delays are additive. So two invocations
+of '-D 10:1', is roughly equivalent to a single invocation
+of '-D 10:2'. This also means, one can specify multiple
+lanes with differing target latencies. For example, an
+invocation of '-D 10:1' followed by '-D 25:2' will
+create 3 lanes on the device; one lane with a latency
+of 10 ms and two lanes with a 25 ms latency.
+
+.TP

+.SH DESCRIPTION
+.sp
+.LP
+The \fBzpool\fR command configures \fBZFS\fR storage pools. A storage pool is a collection of devices that provides physical storage and data replication for \fBZFS\fR datasets.
+.sp
+.LP
+All datasets within a storage pool share the same space. See \fBzfs\fR(8) for information on managing datasets.
+.SS "Virtual Devices (\fBvdev\fRs)"
+.sp
+.LP
+A "virtual device" describes a single device or a collection of devices organized according to certain performance and fault characteristics. The following virtual devices are supported:
+.sp
+.ne 2
+.na
+\fB\fBdisk\fR\fR
+.ad
+.RS 10n
+A block device, typically located under \fB/dev\fR. \fBZFS\fR can use individual partitions, though the recommended mode of operation is to use whole disks. A disk can be specified by a full path, or it can be a shorthand name (the relative portion of the path under "/dev"). For example, "sda" is equivalent to "/dev/sda". A whole disk can be specified by omitting the partition designation. When given a whole disk, \fBZFS\fR automatically labels the disk, if necessary.
+.RE
+
+.sp
+.ne 2
+.na
+\fB\fBfile\fR\fR
+.ad
+.RS 10n
+A regular file. The use of files as a backing store is strongly discouraged. It is designed primarily for experimental purposes, as the fault tolerance of a file is only as good as the file system of which it is a part. A file must be specified by a full path.
+.RE
+
+.sp
+.ne 2
+.na
+\fB\fBmirror\fR\fR
+.ad
+.RS 10n
+A mirror of two or more devices. Data is replicated in an identical fashion across all components of a mirror. A mirror with \fIN\fR disks of size \fIX\fR can hold \fIX\fR bytes and can withstand (\fIN-1\fR) devices failing before data integrity is compromised.
+.RE
+
+.sp
+.ne 2
+.na
+\fB\fBraidz\fR\fR
+.ad
+.br
+.na
+\fB\fBraidz1\fR\fR
+.ad
+.br
+.na
+\fB\fBraidz2\fR\fR
+.ad
+.br
+.na
+\fB\fBraidz3\fR\fR
+.ad
+.RS 10n
+A variation on \fBRAID-5\fR that allows for better distribution of parity and eliminates the "\fBRAID-5\fR write hole" (in which data and parity become inconsistent after a power loss). Data and parity is striped across all disks within a \fBraidz\fR group.
+.sp
+A \fBraidz\fR group can have single-, double- , or triple parity, meaning that the \fBraidz\fR group can sustain one, two, or three failures, respectively, without losing any data. The \fBraidz1\fR \fBvdev\fR type specifies a single-parity \fBraidz\fR group; the \fBraidz2\fR \fBvdev\fR type specifies a double-parity \fBraidz\fR group; and the \fBraidz3\fR \fBvdev\fR type specifies a triple-parity \fBraidz\fR group. The \fBraidz\fR \fBvdev\fR type is an alias for \fBraidz1\fR.
+.sp
+A \fBraidz\fR group with \fIN\fR disks of size \fIX\fR with \fIP\fR parity disks can hold approximately (\fIN-P\fR)*\fIX\fR bytes and can withstand \fIP\fR device(s) failing before data integrity is compromised. The minimum number of devices in a \fBraidz\fR group is one more than the number of parity disks. The recommended number is between 3 and 9 to help increase performance.
+.RE
+
+.sp
+.ne 2
+.na
+\fB\fBspare\fR\fR
+.ad
+.RS 10n
+A special pseudo-\fBvdev\fR which keeps track of available hot spares for a pool. For more information, see the "Hot Spares" section.
+.RE
+
+.sp
+.ne 2
+.na
+\fB\fBlog\fR\fR
+.ad
+.RS 10n
+A separate-intent log device. If more than one log device is specified, then writes are load-balanced between devices. Log devices can be mirrored. However, \fBraidz\fR \fBvdev\fR types are not supported for the intent log. For more information, see the "Intent Log" section.
+.RE
+
+.sp
+.ne 2
+.na
+\fB\fBcache\fR\fR
+.ad
+.RS 10n
+A device used to cache storage pool data. A cache device cannot be configured as a mirror or \fBraidz\fR group. For more information, see the "Cache Devices" section.
+.RE
+
+.sp
+.LP
+Virtual devices cannot be nested, so a mirror or \fBraidz\fR virtual device can only contain files or disks. Mirrors of mirrors (or other combinations) are not allowed.
+.sp
+.LP
+A pool can have any number of virtual devices at the top of the configuration (known as "root vdevs"). Data is dynamically distributed across all top-level devices to balance data among devices. As new virtual devices are added, \fBZFS\fR automatically places data on the newly available devices.
+.sp
+.LP
+Virtual devices are specified one at a time on the command line, separated by whitespace. The keywords "mirror" and "raidz" are used to distinguish where a group ends and another begins. For example, the following creates two root vdevs, each a mirror of two disks:
+.sp
+.in +2
+.nf
+# \fBzpool create mypool mirror sda sdb mirror sdc sdd\fR
+.fi
+.in -2
+.sp
+
+.SS "Device Failure and Recovery"
+.sp
+.LP
+\fBZFS\fR supports a rich set of mechanisms for handling device failure and data corruption. All metadata and data is checksummed, and \fBZFS\fR automatically repairs bad data from a good copy when corruption is detected.
+.sp
+.LP
+In order to take advantage of these features, a pool must make use of some form of redundancy, using either mirrored or \fBraidz\fR groups. While \fBZFS\fR supports running in a non-redundant configuration, where each root vdev is simply a disk or file, this is strongly discouraged. A single case of bit corruption can render some or all of your data unavailable.
+.sp
+.LP
+A pool's health status is described by one of three states: online, degraded, or faulted. An online pool has all devices operating normally. A degraded pool is one in which one or more devices have failed, but the data is still available due to a redundant configuration. A faulted pool has corrupted metadata, or one or more faulted devices, and insufficient replicas to continue functioning.

+.SS "Hot Spares"
+.sp
+.LP
+\fBZFS\fR allows devices to be associated with pools as "hot spares". These devices are not actively used in the pool, but when an active device fails, it is automatically replaced by a hot spare. To create a pool with hot spares, specify a "spare" \fBvdev\fR with any number of devices. For example,
+.sp
+.in +2
+.nf
+# zpool create pool mirror sda sdb spare sdc sdd
+.fi
+.in -2
+.sp
+
+.sp
+.LP
+Spares can be shared across multiple pools, and can be added with the "\fBzpool add\fR" command and removed with the "\fBzpool remove\fR" command. Once a spare replacement is initiated, a new "spare" \fBvdev\fR is created within the configuration that will remain there until the original device is replaced. At this point, the hot spare becomes available again.
+.sp
+.LP
+If a pool has a shared spare that is currently being used, the pool can not be exported since other pools may use this shared spare, which may lead to potential data corruption.
+.sp
+.LP
+An in-progress spare replacement can be cancelled by detaching the hot spare. If the original faulted device is detached, then the hot spare assumes its place in the configuration, and is removed from the spare list of all active pools.
+.sp
+.LP
+Spares cannot replace log devices.
+.SS "Intent Log"
+.sp
+.LP
+The \fBZFS\fR Intent Log (\fBZIL\fR) satisfies \fBPOSIX\fR requirements for synchronous transactions. For instance, databases often require their transactions to be on stable storage devices when returning from a system call. \fBNFS\fR and other applications can also use \fBfsync\fR() to ensure data stability. By default, the intent log is allocated from blocks within the main pool. However, it might be possible to get better performance using separate intent log devices such as \fBNVRAM\fR or a dedicated disk. For example:
+.sp
+.in +2
+.nf
+\fB# zpool create pool sda sdb log sdc\fR
+.fi
+.in -2
+.sp
+
+.sp
+.LP
+Multiple log devices can also be specified, and they can be mirrored. See the EXAMPLES section for an example of mirroring multiple log devices.
+.sp
+.LP
+Log devices can be added, replaced, attached, detached, and imported and exported as part of the larger pool. Mirrored log devices can be removed by specifying the top-level mirror for the log.
+.SS "Cache Devices"
+.sp
+.LP
+Devices can be added to a storage pool as "cache devices." These devices provide an additional layer of caching between main memory and disk. For read-heavy workloads, where the working set size is much larger than what can be cached in main memory, using cache devices allow much more of this working set to be served from low latency media. Using cache devices provides the greatest performance improvement for random read-workloads of mostly static content.
+.sp
+.LP
+To create a pool with cache devices, specify a "cache" \fBvdev\fR with any number of devices. For example:
+.sp
+.in +2
+.nf
+\fB# zpool create pool sda sdb cache sdc sdd\fR
+.fi
+.in -2
+.sp
+
+.sp
+.LP
+Cache devices cannot be mirrored or part of a \fBraidz\fR configuration. If a read error is encountered on a cache device, that read \fBI/O\fR is reissued to the original storage pool device, which might be part of a mirrored or \fBraidz\fR configuration.
+.sp
+.LP
+The content of the cache devices is considered volatile, as is the case with other system caches.

+.sp
+.LP
+The space usage properties report actual physical space available to the storage pool. The physical space can be different from the total amount of space that any contained datasets can actually use. The amount of space used in a \fBraidz\fR configuration depends on the characteristics of the data being written. In addition, \fBZFS\fR reserves some space for internal accounting that the \fBzfs\fR(8) command takes into account, but the \fBzpool\fR command does not. For non-full pools of a reasonable size, these effects should be invisible. For small pools, or pools that are close to being completely full, these discrepancies may become more noticeable.

+The following property can be set at creation time:
+.sp
+.ne 2
+.na
+\fB\fBashift\fR=\fIashift\fR\fR
+.ad
+.sp .6
+.RS 4n
+Pool sector size exponent, to the power of 2 (internally referred to as "ashift"). Values from 9 to 13, inclusive, are valid; also, the special value 0 (the default) means to auto-detect using the kernel's block layer and a ZFS internal exception list. I/O operations will be aligned to the specified size boundaries. Additionally, the minimum (disk) write size will be set to the specified size, so this represents a space vs. performance trade-off. The typical case for setting this property is when performance is important and the underlying disks use 4KiB sectors but report 512B sectors to the OS (for compatibility reasons); in that case, set \fBashift=12\fR (which is 1<<12 = 4096).
+.LP
+For optimal performance, the pool sector size should be greater than or equal to the sector size of the underlying disks. Since the property cannot be changed after pool creation, if in a given pool, you \fIever\fR want to use drives that \fIreport\fR 4KiB sectors, you must set \fBashift=12\fR at pool creation time.
+.LP

+config VDEV names if a "devid" NVP value is present in the pool's config.
+
+For example, a pool that originated on illumos platform would have a devid
+value in the config and \fBzpool status\fR would fail when listing the config.
+This would also be true for future Linux based pools.
+
+A pool can be stripped of any "devid" values on import or prevented from adding
+them on \fBzpool create\fR or \fBzpool add\fR by setting ZFS_VDEV_DEVID_OPT_OUT.

+ * general optimization:
+ *
+ * even though this approach is described in the standard as
+ * being slower algorithmically, it is 30-40% faster than the
+ * "faster" version under SPARC, because this version has more
+ * of the constraints specified at compile-time and uses fewer
+ * variables (and therefore has better register utilization)
+ * than its "speedier" brother. (i've tried both, trust me)
+ *
+ * for either method given in the spec, there is an "assignment"
+ * phase where the following takes place:
+ *
+ * tmp = (main_computation);
+ * e = d; d = c; c = rotate_left(b, 30); b = a; a = tmp;
+ *
+ * we can make the algorithm go faster by not doing this work,
+ * but just pretending that `d' is now `e', etc. this works
+ * really well and obviates the need for a temporary variable.
+ * however, we still explicitly perform the rotate action,
+ * since it is cheaper on SPARC to do it once than to have to
+ * do it over and over again.

+ * Issue 20/12/2007
+ *
+ * I am grateful to Dag Arne Osvik for many discussions of the techniques that
+ * can be used to optimise AES assembler code on AMD64/EM64T architectures.
+ * Some of the techniques used in this implementation are the result of
+ * suggestions made by him for which I am most grateful.
+ *
+ * An AES implementation for AMD64 processors using the YASM assembler. This
+ * implementation provides only encryption, decryption and hence requires key
+ * scheduling support in C. It uses 8k bytes of tables but its encryption and
+ * decryption performance is very close to that obtained using large tables.
+ * It can use either MS Windows or Gnu/Linux/OpenSolaris OS calling conventions,
+ * which are as follows:
+ * ms windows gnu/linux/opensolaris os
+ *
+ * in_blk rcx rdi
+ * out_blk rdx rsi
+ * context (cx) r8 rdx
+ *
+ * preserved rsi - + rbx, rbp, rsp, r12, r13, r14 & r15
+ * registers rdi - on both
+ *
+ * destroyed - rsi + rax, rcx, rdx, r8, r9, r10 & r11
+ * registers - rdi on both
+ *
+ * The convention used here is that for gnu/linux/opensolaris os.
+ *
+ * This code provides the standard AES block size (128 bits, 16 bytes) and the
+ * three standard AES key sizes (128, 192 and 256 bits). It has the same call
+ * interface as my C implementation. It uses the Microsoft C AMD64 calling
+ * conventions in which the three parameters are placed in rcx, rdx and r8
+ * respectively. The rbx, rsi, rdi, rbp and r12..r15 registers are preserved.
+ *
+ * OpenSolaris Note:
+ * Modified to use GNU/Linux/Solaris calling conventions.
+ * That is parameters are placed in rdi, rsi, rdx, and rcx, respectively.
+ *
+ * AES_RETURN aes_encrypt(const unsigned char in_blk[],
+ * unsigned char out_blk[], const aes_encrypt_ctx cx[1])/
+ *
+ * AES_RETURN aes_decrypt(const unsigned char in_blk[],
+ * unsigned char out_blk[], const aes_decrypt_ctx cx[1])/
+ *
+ * AES_RETURN aes_encrypt_key<NNN>(const unsigned char key[],
+ * const aes_encrypt_ctx cx[1])/
+ *
+ * AES_RETURN aes_decrypt_key<NNN>(const unsigned char key[],
+ * const aes_decrypt_ctx cx[1])/
+ *
+ * AES_RETURN aes_encrypt_key(const unsigned char key[],
+ * unsigned int len, const aes_decrypt_ctx cx[1])/
+ *
+ * AES_RETURN aes_decrypt_key(const unsigned char key[],
+ * unsigned int len, const aes_decrypt_ctx cx[1])/
+ *
+ * where <NNN> is 128, 102 or 256. In the last two calls the length can be in
+ * either bits or bytes.
+ *
+ * Comment in/out the following lines to obtain the desired subroutines. These
+ * selections MUST match those in the C header file aesopt.h
+ */
+#define AES_REV_DKS /* define if key decryption schedule is reversed */
+
+#define LAST_ROUND_TABLES /* define for the faster version using extra tables */
+
+/*
+ * The encryption key schedule has the following in memory layout where N is the
+ * number of rounds (10, 12 or 14):
+ *
+ * lo: | input key (round 0) | / each round is four 32-bit words
+ * | encryption round 1 |
+ * | encryption round 2 |
+ * ....
+ * | encryption round N-1 |
+ * hi: | encryption round N |
+ *
+ * The decryption key schedule is normally set up so that it has the same

+ *
+ * lo: | decryption round 0 | = | encryption round N |
+ * | decryption round 1 | = INV_MIX_COL[ | encryption round N-1 | ]
+ * | decryption round 2 | = INV_MIX_COL[ | encryption round N-2 | ]
+ * .... ....
+ * | decryption round N-1 | = INV_MIX_COL[ | encryption round 1 | ]
+ * hi: | decryption round N | = | input key (round 0) |
+ *
+ * with rounds except the first and last modified using inv_mix_column()
+ * But if AES_REV_DKS is NOT set the order of keys is left as it is for
+ * encryption so that it has to be accessed in reverse when used for
+ * decryption (although the inverse mix column modifications are done)
+ *
+ * lo: | decryption round 0 | = | input key (round 0) |
+ * | decryption round 1 | = INV_MIX_COL[ | encryption round 1 | ]
+ * | decryption round 2 | = INV_MIX_COL[ | encryption round 2 | ]

+ * ---------------------------------------------------------------------------
+ * OpenSolaris OS modifications
+ *
+ * This source originates from Brian Gladman file aes_amd64.asm
+ * in http://fp.gladman.plus.com/AES/aes-src-04-03-08.zip
+ * with these changes:
+ *
+ * 1. Removed MS Windows-specific code within DLL_EXPORT, _SEH_, and
+ * !__GNUC__ ifdefs. Also removed ENCRYPTION, DECRYPTION,
+ * AES_128, AES_192, AES_256, AES_VAR ifdefs.
+ *
+ * 2. Translate yasm/nasm %define and .macro definitions to cpp(1) #define
+ *
+ * 3. Translate yasm/nasm %ifdef/%ifndef to cpp(1) #ifdef
+ *
+ * 4. Translate Intel/yasm/nasm syntax to ATT/OpenSolaris as(1) syntax
+ * (operands reversed, literals prefixed with "$", registers prefixed with "%",
+ * and "[register+offset]", addressing changed to "offset(register)",
+ * parenthesis in constant expressions "()" changed to square brackets "[]",
+ * "." removed from local (numeric) labels, and other changes.
+ * Examples:
+ * Intel/yasm/nasm Syntax ATT/OpenSolaris Syntax
+ * mov rax,(4*20h) mov $[4*0x20],%rax
+ * mov rax,[ebx+20h] mov 0x20(%ebx),%rax
+ * lea rax,[ebx+ecx] lea (%ebx,%ecx),%rax
+ * sub rax,[ebx+ecx*4-20h] sub -0x20(%ebx,%ecx,4),%rax
+ *
+ * 5. Added OpenSolaris ENTRY_NP/SET_SIZE macros from
+ * /usr/include/sys/asm_linkage.h, lint(1B) guards, and dummy C function
+ * definitions for lint.
+ *
+ * 6. Renamed functions and reordered parameters to match OpenSolaris:
+ * Original Gladman interface:
+ * int aes_encrypt(const unsigned char *in,
+ * unsigned char *out, const aes_encrypt_ctx cx[1])/
+ * int aes_decrypt(const unsigned char *in,
+ * unsigned char *out, const aes_encrypt_ctx cx[1])/
+ * Note: aes_encrypt_ctx contains ks, a 60 element array of uint32_t,
+ * and a union type, inf., containing inf.l, a uint32_t and
+ * inf.b, a 4-element array of uint32_t. Only b[0] in the array (aka "l") is
+ * used and contains the key schedule length * 16 where key schedule length is
+ * 10, 12, or 14 bytes.
+ *
+ * OpenSolaris OS interface:
+ * void aes_encrypt_amd64(const aes_ks_t *ks, int Nr,
+ * const uint32_t pt[4], uint32_t ct[4])/
+ * void aes_decrypt_amd64(const aes_ks_t *ks, int Nr,
+ * const uint32_t pt[4], uint32_t ct[4])/
+ * typedef union {uint64_t ks64[(MAX_AES_NR + 1) * 4]/
+ * uint32_t ks32[(MAX_AES_NR + 1) * 4]/ } aes_ks_t/
+ * Note: ks is the AES key schedule, Nr is number of rounds, pt is plain text,
+ * ct is crypto text, and MAX_AES_NR is 14.
+ * For the x86 64-bit architecture, OpenSolaris OS uses ks32 instead of ks64.

+ * Intel AES-NI is a new set of Single Instruction Multiple Data (SIMD)
+ * instructions that are going to be introduced in the next generation
+ * of Intel processor, as of 2009. These instructions enable fast and
+ * secure data encryption and decryption, using the Advanced Encryption
+ * Standard (AES), defined by FIPS Publication number 197. The
+ * architecture introduces six instructions that offer full hardware
+ * support for AES. Four of them support high performance data
+ * encryption and decryption, and the other two instructions support
+ * the AES key expansion procedure.

+ * OpenSolaris OS modifications
+ *
+ * This source originates as files aes-intel.S and eng_aesni_asm.pl, in
+ * patches sent sent Dec. 9, 2008 and Dec. 24, 2008, respectively, by
+ * Huang Ying of Intel to the openssl-dev mailing list under the subject
+ * of "Add support to Intel AES-NI instruction set for x86_64 platform".
+ *
+ * This OpenSolaris version has these major changes from the original source:
+ *
+ * 1. Added OpenSolaris ENTRY_NP/SET_SIZE macros from
+ * /usr/include/sys/asm_linkage.h, lint(1B) guards, and dummy C function
+ * definitions for lint.
+ *
+ * 2. Formatted code, added comments, and added #includes and #defines.
+ *
+ * 3. If bit CR0.TS is set, clear and set the TS bit, after and before
+ * calling kpreempt_disable() and kpreempt_enable().
+ * If the TS bit is not set, Save and restore %xmm registers at the beginning
+ * and end of function calls (%xmm* registers are not saved and restored by
+ * during kernel thread preemption).
+ *
+ * 4. Renamed functions, reordered parameters, and changed return value
+ * to match OpenSolaris:
+ *
+ * OpenSSL interface:
+ * int intel_AES_set_encrypt_key(const unsigned char *userKey,
+ * const int bits, AES_KEY *key);
+ * int intel_AES_set_decrypt_key(const unsigned char *userKey,
+ * const int bits, AES_KEY *key);
+ * Return values for above are non-zero on error, 0 on success.
+ *
+ * void intel_AES_encrypt(const unsigned char *in, unsigned char *out,
+ * const AES_KEY *key);
+ * void intel_AES_decrypt(const unsigned char *in, unsigned char *out,
+ * const AES_KEY *key);
+ * typedef struct aes_key_st {
+ * unsigned int rd_key[4 *(AES_MAXNR + 1)];
+ * int rounds;
+ * unsigned int pad[3];
+ * } AES_KEY;
+ * Note: AES_LONG is undefined (that is, Intel uses 32-bit key schedules
+ * (ks32) instead of 64-bit (ks64).
+ * Number of rounds (aka round count) is at offset 240 of AES_KEY.
+ *
+ * OpenSolaris OS interface (#ifdefs removed for readability):
+ * int rijndael_key_setup_dec_intel(uint32_t rk[],
+ * const uint32_t cipherKey[], uint64_t keyBits);
+ * int rijndael_key_setup_enc_intel(uint32_t rk[],
+ * const uint32_t cipherKey[], uint64_t keyBits);
+ * Return values for above are 0 on error, number of rounds on success.
+ *
+ * void aes_encrypt_intel(const aes_ks_t *ks, int Nr,
+ * const uint32_t pt[4], uint32_t ct[4]);
+ * void aes_decrypt_intel(const aes_ks_t *ks, int Nr,
+ * const uint32_t pt[4], uint32_t ct[4]);
+ * typedef union {uint64_t ks64[(MAX_AES_NR + 1) * 4];
+ * uint32_t ks32[(MAX_AES_NR + 1) * 4]; } aes_ks_t;
+ *
+ * typedef union {
+ * uint32_t ks32[((MAX_AES_NR) + 1) * (MAX_AES_NB)];
+ * } aes_ks_t;
+ * typedef struct aes_key {
+ * aes_ks_t encr_ks, decr_ks;
+ * long double align128;
+ * int flags, nr, type;
+ * } aes_key_t;
+ *
+ * Note: ks is the AES key schedule, Nr is number of rounds, pt is plain text,
+ * ct is crypto text, and MAX_AES_NR is 14.
+ * For the x86 64-bit architecture, OpenSolaris OS uses ks32 instead of ks64.
+ *
+ * Note2: aes_ks_t must be aligned on a 0 mod 128 byte boundary.

+ * This file contains the compilation options for AES (Rijndael) and code
+ * that is common across encryption, key scheduling and table generation.
+ *
+ * OPERATION
+ *
+ * These source code files implement the AES algorithm Rijndael designed by
+ * Joan Daemen and Vincent Rijmen. This version is designed for the standard
+ * block size of 16 bytes and for key sizes of 128, 192 and 256 bits (16, 24
+ * and 32 bytes).
+ *
+ * This version is designed for flexibility and speed using operations on
+ * 32-bit words rather than operations on bytes. It can be compiled with
+ * either big or little endian internal byte order but is faster when the
+ * native byte order for the processor is used.
+ *
+ * THE CIPHER INTERFACE
+ *
+ * The cipher interface is implemented as an array of bytes in which lower
+ * AES bit sequence indexes map to higher numeric significance within bytes.
+ */
+
+/*
+ * OpenSolaris changes

+ * 1. BYTE ORDER WITHIN 32 BIT WORDS
+ *
+ * The fundamental data processing units in Rijndael are 8-bit bytes. The
+ * input, output and key input are all enumerated arrays of bytes in which
+ * bytes are numbered starting at zero and increasing to one less than the
+ * number of bytes in the array in question. This enumeration is only used
+ * for naming bytes and does not imply any adjacency or order relationship
+ * from one byte to another. When these inputs and outputs are considered
+ * as bit sequences, bits 8*n to 8*n+7 of the bit sequence are mapped to
+ * byte[n] with bit 8n+i in the sequence mapped to bit 7-i within the byte.
+ * In this implementation bits are numbered from 0 to 7 starting at the
+ * numerically least significant end of each byte. Bit n represents 2^n.
+ *
+ * However, Rijndael can be implemented more efficiently using 32-bit
+ * words by packing bytes into words so that bytes 4*n to 4*n+3 are placed
+ * into word[n]. While in principle these bytes can be assembled into words
+ * in any positions, this implementation only supports the two formats in
+ * which bytes in adjacent positions within words also have adjacent byte
+ * numbers. This order is called big-endian if the lowest numbered bytes
+ * in words have the highest numeric significance and little-endian if the
+ * opposite applies.
+ *
+ * This code can work in either order irrespective of the order used by the
+ * machine on which it runs. Normally the internal byte order will be set
+ * to the order of the processor on which the code is to be run but this
+ * define can be used to reverse this in special situations
+ *
+ * WARNING: Assembler code versions rely on PLATFORM_BYTE_ORDER being set.
+ * This define will hence be redefined later (in section 4) if necessary

+ *
+ * This file contains the code for declaring the tables needed to implement
+ * AES. The file aesopt.h is assumed to be included before this header file.
+ * If there are no global variables, the definitions here can be used to put
+ * the AES tables in a structure so that a pointer can then be added to the
+ * AES context to pass them to the AES routines that need them. If this
+ * facility is used, the calling program has to ensure that this pointer is
+ * managed appropriately. In particular, the value of the t_dec(in, it) item
+ * in the table structure must be set to zero in order to ensure that the
+ * tables are initialised. In practice the three code sequences in aeskey.c
+ * that control the calls to aes_init() and the aes_init() routine itself will
+ * have to be changed for a specific implementation. If global variables are
+ * available it will generally be preferable to use them with the precomputed
+ * FIXED_TABLES option that uses static global tables.
+ *
+ * The following defines can be used to control the way the tables
+ * are defined, initialised and used in embedded environments that
+ * require special features for these purposes
+ *
+ * the 't_dec' construction is used to declare fixed table arrays
+ * the 't_set' construction is used to set fixed table values
+ * the 't_use' construction is used to access fixed table values
+ *
+ * 256 byte tables:
+ *
+ * t_xxx(s, box) => forward S box
+ * t_xxx(i, box) => inverse S box
+ *
+ * 256 32-bit word OR 4 x 256 32-bit word tables:
+ *
+ * t_xxx(f, n) => forward normal round
+ * t_xxx(f, l) => forward last round
+ * t_xxx(i, n) => inverse normal round
+ * t_xxx(i, l) => inverse last round
+ * t_xxx(l, s) => key schedule table
+ * t_xxx(i, m) => key schedule table
+ *
+ * Other variables and tables:
+ *
+ * t_xxx(r, c) => the rcon table
+ */

+ * ====================================================================
+ * OpenSolaris OS modifications
+ *
+ * This source originates as file galois_hash_asm.c from
+ * Intel Corporation dated September 21, 2009.
+ *
+ * This OpenSolaris version has these major changes from the original source:
+ *
+ * 1. Added OpenSolaris ENTRY_NP/SET_SIZE macros from
+ * /usr/include/sys/asm_linkage.h, lint(1B) guards, and a dummy C function
+ * definition for lint.
+ *
+ * 2. Formatted code, added comments, and added #includes and #defines.
+ *
+ * 3. If bit CR0.TS is set, clear and set the TS bit, after and before
+ * calling kpreempt_disable() and kpreempt_enable().
+ * If the TS bit is not set, Save and restore %xmm registers at the beginning
+ * and end of function calls (%xmm* registers are not saved and restored by
+ * during kernel thread preemption).
+ *
+ * 4. Removed code to perform hashing. This is already done with C macro
+ * GHASH in gcm.c. For better performance, this removed code should be
+ * reintegrated in the future to replace the C GHASH macro.
+ *
+ * 5. Added code to byte swap 16-byte input and output.
+ *
+ * 6. Folded in comments from the original C source with embedded assembly
+ * (SB_w_shift_xor.c)
+ *
+ * 7. Renamed function and reordered parameters to match OpenSolaris:
+ * Intel interface:
+ * void galois_hash_asm(unsigned char *hk, unsigned char *s,
+ * unsigned char *d, int length)
+ * OpenSolaris OS interface:
+ * void gcm_mul_pclmulqdq(uint64_t *x_in, uint64_t *y, uint64_t *res);

+ * sha1_block procedure for x86_64.
+ *
+ * It was brought to my attention that on EM64T compiler-generated code
+ * was far behind 32-bit assembler implementation. This is unlike on
+ * Opteron where compiler-generated code was only 15% behind 32-bit
+ * assembler, which originally made it hard to motivate the effort.
+ * There was suggestion to mechanically translate 32-bit code, but I
+ * dismissed it, reasoning that x86_64 offers enough register bank
+ * capacity to fully utilize SHA-1 parallelism. Therefore this fresh
+ * implementation:-) However! While 64-bit code does performs better
+ * on Opteron, I failed to beat 32-bit assembler on EM64T core. Well,
+ * x86_64 does offer larger *addressable* bank, but out-of-order core
+ * reaches for even more registers through dynamic aliasing, and EM64T
+ * core must have managed to run-time optimize even 32-bit code just as
+ * good as 64-bit one. Performance improvement is summarized in the
+ * following table:
+ *
+ * gcc 3.4 32-bit asm cycles/byte
+ * Opteron +45% +20% 6.8
+ * Xeon P4 +65% +0% 9.9

+ *
+ * sha256/512_block procedure for x86_64.
+ *
+ * 40% improvement over compiler-generated code on Opteron. On EM64T
+ * sha256 was observed to run >80% faster and sha512 - >40%. No magical
+ * tricks, just straight implementation... I really wonder why gcc
+ * [being armed with inline assembler] fails to generate as fast code.
+ * The only thing which is cool about this module is that it's very
+ * same instruction sequence used for both SHA-256 and SHA-512. In
+ * former case the instructions operate on 32-bit operands, while in
+ * latter - on 64-bit ones. All I had to do is to get one flavor right,
+ * the other one passed the test right away:-)
+ *
+ * sha256_block runs in ~1005 cycles on Opteron, which gives you
+ * asymptotic performance of 64*1000/1005=63.7MBps times CPU clock
+ * frequency in GHz. sha512_block runs in ~1275 cycles, which results
+ * in 128*1000/1275=100MBps per GHz. Is there room for improvement?
+ * Well, if you compare it to IA-64 implementation, which maintains
+ * X[16] in register bank[!], tends to 4 instructions per CPU clock
+ * cycle and runs in 1003 cycles, 1275 is very good result for 3-way
+ * issue Opteron pipeline and X[16] maintained in memory. So that *if*
+ * there is a way to improve it, *then* the only way would be to try to
+ * offload X[16] updates to SSE unit, but that would require "deeper"
+ * loop unroll, which in turn would naturally cause size blow-up, not
+ * to mention increased complexity! And once again, only *if* it's
+ * actually possible to noticeably improve overall ILP, instruction
+ * level parallelism, on a given CPU implementation in this case.
+ *
+ * Special note on Intel EM64T. While Opteron CPU exhibits perfect
+ * perfromance ratio of 1.5 between 64- and 32-bit flavors [see above],
+ * [currently available] EM64T CPUs apparently are far from it. On the
+ * contrary, 64-bit version, sha512_block, is ~30% *slower* than 32-bit
+ * sha256_block:-( This is presumably because 64-bit shifts/rotates
+ * apparently are not atomic instructions, but implemented in microcode.

+ * 3. Removed x86_64-xlate.pl script (not needed for as(1) or gas(1)
+ * assemblers). Replaced the .picmeup macro with assembler code.
+ *
+ * 4. Added 8 to $ctx, as OpenSolaris OS has an extra 4-byte field, "algotype",
+ * at the beginning of SHA2_CTX (the next field is 8-byte aligned).

+ *
+ * sha256/512_block procedure for x86_64.
+ *
+ * 40% improvement over compiler-generated code on Opteron. On EM64T
+ * sha256 was observed to run >80% faster and sha512 - >40%. No magical
+ * tricks, just straight implementation... I really wonder why gcc
+ * [being armed with inline assembler] fails to generate as fast code.
+ * The only thing which is cool about this module is that it's very
+ * same instruction sequence used for both SHA-256 and SHA-512. In
+ * former case the instructions operate on 32-bit operands, while in
+ * latter - on 64-bit ones. All I had to do is to get one flavor right,
+ * the other one passed the test right away:-)
+ *
+ * sha256_block runs in ~1005 cycles on Opteron, which gives you
+ * asymptotic performance of 64*1000/1005=63.7MBps times CPU clock
+ * frequency in GHz. sha512_block runs in ~1275 cycles, which results
+ * in 128*1000/1275=100MBps per GHz. Is there room for improvement?
+ * Well, if you compare it to IA-64 implementation, which maintains
+ * X[16] in register bank[!], tends to 4 instructions per CPU clock
+ * cycle and runs in 1003 cycles, 1275 is very good result for 3-way
+ * issue Opteron pipeline and X[16] maintained in memory. So that *if*
+ * there is a way to improve it, *then* the only way would be to try to
+ * offload X[16] updates to SSE unit, but that would require "deeper"
+ * loop unroll, which in turn would naturally cause size blow-up, not
+ * to mention increased complexity! And once again, only *if* it's
+ * actually possible to noticeably improve overall ILP, instruction
+ * level parallelism, on a given CPU implementation in this case.
+ *
+ * Special note on Intel EM64T. While Opteron CPU exhibits perfect
+ * perfromance ratio of 1.5 between 64- and 32-bit flavors [see above],
+ * [currently available] EM64T CPUs apparently are far from it. On the
+ * contrary, 64-bit version, sha512_block, is ~30% *slower* than 32-bit
+ * sha256_block:-( This is presumably because 64-bit shifts/rotates
+ * apparently are not atomic instructions, but implemented in microcode.

+/*
+ * Changes made to the original Illumos Crypto Layer for the ICP:
+ *
+ * Several changes were needed to allow the Illumos Crypto Layer
+ * to work in the Linux kernel. Almost all of the changes fall into
+ * one of the following categories:
+ *
+ * 1) Moving the syntax to the C90: This was mostly a matter of
+ * changing func() definitions to func(void). In a few cases,
+ * initializations of structs with unions needed to have brackets
+ * added.
+ *
+ * 2) Changes to allow userspace compilation: The ICP is meant to be
+ * compiled and used in both userspace and kernel space (for ztest and
+ * libzfs), so the _KERNEL macros did not make sense anymore. For the
+ * same reason, many header includes were also changed to use
+ * sys/zfs_context.h
+ *
+ * 3) Moving to a statically compiled architecture: At some point in
+ * the future it may make sense to have encryption algorithms that are
+ * loadable into the ICP at runtime via separate kernel modules.
+ * However, considering that this code will probably not see much use
+ * outside of zfs and zfs encryption only requires aes and sha256
+ * algorithms it seemed like more trouble than it was worth to port over
+ * Illumos's kernel module structure to a Linux kernel module. In
+ * addition, The Illumos code related to keeping track of kernel modules
+ * is very much tied to the Illumos OS and proved difficult to port to
+ * Linux. Therefore, the structure of the ICP was simplified to work
+ * statically and several pieces of code responsible for keeping track
+ * of Illumos kernel modules were removed and simplified. All module
+ * initialization and destruction is now called in this file during
+ * Linux kernel module loading and unloading.
+ *
+ * 4) Adding destructors: The Illumos Crypto Layer is built into
+ * the Illumos kernel and is not meant to be unloaded. Some destructors
+ * were added to allow the ICP to be unloaded without leaking
+ * structures.
+ *
+ * 5) Removing CRYPTO_DATA_MBLK related structures and code:
+ * crypto_data_t can have 3 formats, CRYPTO_DATA_RAW, CRYPTO_DATA_UIO,
+ * and CRYPTO_DATA_MBLK. ZFS only requires the first 2 formats, as the
+ * last one is related to streamed data. To simplify the port, code
+ * related to this format was removed.
+ *
+ * 6) Changes for architecture specific code: Some changes were needed
+ * to make architecture specific assembly compile. The biggest change
+ * here was to functions related to detecting CPU capabilities for amd64.
+ * The Illumos Crypto Layer used called into the Illumos kernel's API
+ * to discover these. They have been converted to instead use the
+ * 'cpuid' instruction as per the Intel spec. In addition, references to
+ * the sun4u' and sparc architectures have been removed so that these
+ * will use the generic implementation.
+ *
+ * 7) Removing sha384 and sha512 code: The sha code was actually very
+ * wasy to port. However, the generic sha384 and sha512 code actually
+ * exceeds the stack size on arm and powerpc architectures. In an effort
+ * to remove warnings, this code was removed.
+ *
+ * 8) Change large allocations from kmem_alloc() to vmem_alloc(): In
+ * testing the ICP with the ZFS encryption code, a few allocations were
+ * found that could potentially be very large. These caused the SPL to
+ * throw warnings and so they were changed to use vmem_alloc().
+ *
+ * 9) Makefiles: Makefiles were added that would work with the existing
+ * ZFS Makefiles.

+ * mod_hash: flexible hash table implementation.
+ *
+ * This is a reasonably fast, reasonably flexible hash table implementation
+ * which features pluggable hash algorithms to support storing arbitrary keys
+ * and values. It is designed to handle small (< 100,000 items) amounts of
+ * data. The hash uses chaining to resolve collisions, and does not feature a
+ * mechanism to grow the hash. Care must be taken to pick nchains to be large
+ * enough for the application at hand, or lots of time will be wasted searching
+ * hash chains.
+ *
+ * The client of the hash is required to supply a number of items to support
+ * the various hash functions:
+ *
+ * - Destructor functions for the key and value being hashed.
+ * A destructor is responsible for freeing an object when the hash
+ * table is no longer storing it. Since keys and values can be of
+ * arbitrary type, separate destructors for keys & values are used.
+ * These may be mod_hash_null_keydtor and mod_hash_null_valdtor if no
+ * destructor is needed for either a key or value.
+ *
+ * - A hashing algorithm which returns a uint_t representing a hash index
+ * The number returned need _not_ be between 0 and nchains. The mod_hash
+ * code will take care of doing that. The second argument (after the
+ * key) to the hashing function is a void * that represents
+ * hash_alg_data-- this is provided so that the hashing algrorithm can
+ * maintain some state across calls, or keep algorithm-specific
+ * constants associated with the hash table.
+ *
+ * A pointer-hashing and a string-hashing algorithm are supplied in
+ * this file.
+ *
+ * - A key comparator (a la qsort).
+ * This is used when searching the hash chain. The key comparator
+ * determines if two keys match. It should follow the return value
+ * semantics of strcmp.
+ *
+ * string and pointer comparators are supplied in this file.
+ *
+ * mod_hash_create_strhash() and mod_hash_create_ptrhash() provide good
+ * examples of how to create a customized hash table.
+ *
+ * Basic hash operations:
+ *
+ * mod_hash_create_strhash(name, nchains, dtor),
+ * create a hash using strings as keys.
+ * NOTE: This create a hash which automatically cleans up the string
+ * values it is given for keys.
+ *
+ * mod_hash_create_ptrhash(name, nchains, dtor, key_elem_size):
+ * create a hash using pointers as keys.
+ *
+ * mod_hash_create_extended(name, nchains, kdtor, vdtor,
+ * hash_alg, hash_alg_data,
+ * keycmp, sleep)
+ * create a customized hash table.
+ *

+/*
+ * ARC operation:
+ *
+ * Every block that is in the ARC is tracked by an arc_buf_hdr_t structure.
+ * This structure can point either to a block that is still in the cache or to
+ * one that is only accessible in an L2 ARC device, or it can provide
+ * information about a block that was recently evicted. If a block is
+ * only accessible in the L2ARC, then the arc_buf_hdr_t only has enough
+ * information to retrieve it from the L2ARC device. This information is
+ * stored in the l2arc_buf_hdr_t sub-structure of the arc_buf_hdr_t. A block
+ * that is in this state cannot access the data directly.
+ *
+ * Blocks that are actively being referenced or have not been evicted
+ * are cached in the L1ARC. The L1ARC (l1arc_buf_hdr_t) is a structure within
+ * the arc_buf_hdr_t that will point to the data block in memory. A block can
+ * only be read by a consumer if it has an l1arc_buf_hdr_t. The L1ARC
+ * caches data in two ways -- in a list of ARC buffers (arc_buf_t) and
+ * also in the arc_buf_hdr_t's private physical data block pointer (b_pdata).
+ *
+ * The L1ARC's data pointer may or may not be uncompressed. The ARC has the
+ * ability to store the physical data (b_pdata) associated with the DVA of the
+ * arc_buf_hdr_t. Since the b_pdata is a copy of the on-disk physical block,
+ * it will match its on-disk compression characteristics. This behavior can be
+ * disabled by setting 'zfs_compressed_arc_enabled' to B_FALSE. When the
+ * compressed ARC functionality is disabled, the b_pdata will point to an
+ * uncompressed version of the on-disk data.
+ *
+ * Data in the L1ARC is not accessed by consumers of the ARC directly. Each
+ * arc_buf_hdr_t can have multiple ARC buffers (arc_buf_t) which reference it.
+ * Each ARC buffer (arc_buf_t) is being actively accessed by a specific ARC
+ * consumer. The ARC will provide references to this data and will keep it
+ * cached until it is no longer in use. The ARC caches only the L1ARC's physical
+ * data block and will evict any arc_buf_t that is no longer referenced. The
+ * amount of memory consumed by the arc_buf_ts' data buffers can be seen via the
+ * "overhead_size" kstat.
+ *
+ * Depending on the consumer, an arc_buf_t can be requested in uncompressed or
+ * compressed form. The typical case is that consumers will want uncompressed
+ * data, and when that happens a new data buffer is allocated where the data is
+ * decompressed for them to use. Currently the only consumer who wants
+ * compressed arc_buf_t's is "zfs send", when it streams data exactly as it
+ * exists on disk. When this happens, the arc_buf_t's data buffer is shared
+ * with the arc_buf_hdr_t.
+ *
+ * Here is a diagram showing an arc_buf_hdr_t referenced by two arc_buf_t's. The
+ * first one is owned by a compressed send consumer (and therefore references
+ * the same compressed data buffer as the arc_buf_hdr_t) and the second could be
+ * used by any other consumer (and has its own uncompressed copy of the data
+ * buffer).

+ *
+ * When a consumer reads a block, the ARC must first look to see if the
+ * arc_buf_hdr_t is cached. If the hdr is cached then the ARC allocates a new
+ * arc_buf_t and either copies uncompressed data into a new data buffer from an
+ * existing uncompressed arc_buf_t, decompresses the hdr's b_pdata buffer into a
+ * new data buffer, or shares the hdr's b_pdata buffer, depending on whether the
+ * hdr is compressed and the desired compression characteristics of the
+ * arc_buf_t consumer. If the arc_buf_t ends up sharing data with the
+ * arc_buf_hdr_t and both of them are uncompressed then the arc_buf_t must be
+ * the last buffer in the hdr's b_buf list, however a shared compressed buf can
+ * be anywhere in the hdr's list.
+ *
+ * The diagram below shows an example of an uncompressed ARC hdr that is

+ *
+ * Writing to the ARC requires that the ARC first discard the hdr's b_pdata
+ * since the physical block is about to be rewritten. The new data contents
+ * will be contained in the arc_buf_t. As the I/O pipeline performs the write,
+ * it may compress the data before writing it to disk. The ARC will be called
+ * with the transformed data and will bcopy the transformed on-disk block into
+ * a newly allocated b_pdata. Writes are always done into buffers which have
+ * either been loaned (and hence are new and don't have other readers) or
+ * buffers which have been released (and hence have their own hdr, if there
+ * were originally other readers of the buf's original hdr). This ensures that
+ * the ARC only needs to update a single buf and its hdr after a write occurs.
+ *
+ * When the L2ARC is in use, it will also take advantage of the b_pdata. The
+ * L2ARC will always write the contents of b_pdata to the L2ARC. This means
+ * that when compressed ARC is enabled that the L2ARC blocks are identical
+ * to the on-disk block in the main data pool. This provides a significant
+ * advantage since the ARC can leverage the bp's checksum when reading from the
+ * L2ARC to determine if the contents are valid. However, if the compressed
+ * ARC is disabled, then the L2ARC's block must be transformed to look
+ * like the physical block in the main data pool before comparing the
+ * checksum and determining its validity.

+ * DATA RECONSTRUCTION
+ *
+ * Data reconstruction process consists of two phases:
+ * - Syndrome calculation
+ * - Data reconstruction
+ *
+ * Syndrome is calculated by generating parity using available data columns
+ * and zeros in places of erasure. Existing parity is added to corresponding
+ * syndrome value to obtain the [P|Q|R]syn values from equation:
+ * P = Psyn + Dx + Dy + Dz
+ * Q = Qsyn + 2^x * Dx + 2^y * Dy + 2^z * Dz
+ * R = Rsyn + 4^x * Dx + 4^y * Dy + 4^z * Dz
+ *
+ * For data reconstruction phase, the corresponding equations are solved
+ * for missing data (Dx, Dy, Dz). This generally involves multiplying known
+ * symbols by an coefficient and adding them together. The multiplication
+ * constant coefficients are calculated ahead of the operation in
+ * raidz_rec_[q|r|pq|pq|qr|pqr]_coeff() functions.
+ *
+ * IMPLEMENTATION NOTE: RAID-Z block can have complex geometry, with "big"
+ * and "short" columns.
+ * For this reason, reconstruction is performed in minimum of
+ * two steps. First, from offset 0 to short_size, then from short_size to
+ * short_size. Calculation functions REC_[*]_BLOCK() are implemented to work
+ * over both ranges. The split also enables removal of conditional expressions
+ * from loop bodies, improving throughput of SIMD implementations.
+ * For the best performance, all functions marked with raidz_inline attribute
+ * must be inlined by compiler.

* checksum function of the appropriate strength. When reading a block,

+ *
+ * SALTED CHECKSUMS
+ *
+ * To enable the use of less secure hash algorithms with dedup, we
+ * introduce the notion of salted checksums (MACs, really). A salted
+ * checksum is fed both a random 256-bit value (the salt) and the data
+ * to be checksummed. This salt is kept secret (stored on the pool, but
+ * never shown to the user). Thus even if an attacker knew of collision
+ * weaknesses in the hash algorithm, they won't be able to mount a known
+ * plaintext attack on the DDT, since the actual hash value cannot be
+ * known ahead of time. How the salt is used is algorithm-specific
+ * (some might simply prefix it to the data block, others might need to
+ * utilize a full-blown HMAC). On disk the salt is stored in a ZAP
+ * object in the MOS (DMU_POOL_CHECKSUM_SALT).
+ *
+ * CONTEXT TEMPLATES
+ *
+ * Some hashing algorithms need to perform a substantial amount of
+ * initialization work (e.g. salted checksums above may need to pre-hash
+ * the salt) before being able to process data. Performing this
+ * redundant work for each block would be wasteful, so we instead allow
+ * a checksum algorithm to do the work once (the first time it's used)
+ * and then keep this pre-initialized context as a template inside the
+ * spa_t (spa_cksum_tmpls). If the zio_checksum_info_t contains
+ * non-NULL ci_tmpl_init and ci_tmpl_free callbacks, they are used to
+ * construct and destruct the pre-initialized checksum context. The
+ * pre-initialized context is then reused during each checksum
+ * invocation and passed to the checksum function.

+# Here's how it all works:
+#
+# The general idea is to build up
+# an intent log from a bunch of diverse user commands
+# without actually committing them to the file system.
+# Then copy the file system, replay the intent
+# log and compare the file system and the copy.
+#
+# To enable this automated testing of the intent log
+# requires some but minimal support from the file system.
+# In particular, a "freeze" command is required to flush
+# the in-flight transactions; to stop the actual
+# committing of transactions; and to ensure no deltas are
+# discarded. All deltas past a freeze point are kept for
+# replay and comparison later. Here is the flow:
+#
+# create an empty file system (FS)
+# freeze FS
+# run various user commands that create files, directories and ACLs
+# copy FS to temporary location (COPY)
+# unmount filesystem
+# <at this stage FS is empty again and unfrozen, and the
+# intent log contains a complete set of deltas to replay it>
+# remount FS <which replays the intent log>
+# compare FS against the COPY
+#

+# Verify that an assortment of known good reference pools can be imported
+# using different versions of the ZoL code.
+#
+# By default references pools for the major ZFS implementation will be
+# checked against the most recent ZoL tags and the master development branch.
+# Alternate tags or branches may be verified with the '-s <src-tag> option.
+# Passing the keyword "installed" will instruct the script to test whatever
+# version is installed.
+#
+# Preferentially a reference pool is used for all tests. However, if one
+# does not exist and the pool-tag matches one of the src-tags then a new
+# reference pool will be created using binaries from that source build.
+# This is particularly useful when you need to test your changes before
+# opening a pull request. The keyword 'all' can be used as short hand
+# refer to all available reference pools.
+#
+# New reference pools may be added by placing a bzip2 compressed tarball
+# of the pool in the scripts/zfs-images directory and then passing
+# the -p <pool-tag> option. To increase the test coverage reference pools
+# should be collected for all the major ZFS implementations. Having these
+# pools easily available is also helpful to the developers.
+#
+# Care should be taken to run these tests with a kernel supported by all
+# the listed tags. Otherwise build failure will cause false positives.
+#
+#
+# EXAMPLES:
+#
+# The following example will verify the zfs-0.6.2 tag, the master branch,
+# and the installed zfs version can correctly import the listed pools.
+# Note there is no reference pool available for master and installed but
+# because binaries are available one is automatically constructed. The
+# working directory is also preserved between runs (-k) preventing the
+# need to rebuild from source for multiple runs.

+# ZFS Test Suite README
+
+1) Building and installing the ZFS Test Suite
+
+The ZFS Test Suite runs under the test-runner framework. This framework
+is built along side the standard ZFS utilities and is included as part of
+zfs-test package. The zfs-test package can be built from source as follows:
+
+ $ ./configure
+ $ make pkg-utils
+
+The resulting packages can be installed using the rpm or dpkg command as
+appropriate for your distributions. Alternately, if you have installed
+ZFS from a distributions repository (not from source) the zfs-test package
+may be provided for your distribution.
+
+ - Installed from source
+ $ rpm -ivh ./zfs-test*.rpm, or
+ $ dpkg -i ./zfs-test*.deb,
+
+ - Installed from package repository
+ $ yum install zfs-test
+ $ apt-get install zfs-test
+
+2) Running the ZFS Test Suite
+
+The pre-requisites for running the ZFS Test Suite are:
+
+ * Three scratch disks
+ * Specify the disks you wish to use in the $DISKS variable, as a
+ space delimited list like this: DISKS='vdb vdc vdd'. By default
+ the zfs-tests.sh sciprt will construct three loopback devices to
+ be used for testing: DISKS='loop0 loop1 loop2'.
+ * A non-root user with a full set of basic privileges and the ability
+ to sudo(8) to root without a password to run the test.
+ * Specify any pools you wish to preserve as a space delimited list in
+ the $KEEP variable. All pools detected at the start of testing are
+ added automatically.
+ * The ZFS Test Suite will add users and groups to test machine to
+ verify functionality. Therefore it is strongly advised that a
+ dedicated test machine, which can be a VM, be used for testing.
+
+Once the pre-requisites are satisfied simply run the zfs-tests.sh script:
+
+ $ /usr/share/zfs/zfs-tests.sh
+
+Alternately, the zfs-tests.sh script can be run from the source tree to allow
+developers to rapidly validate their work. In this mode the ZFS utilities and
+modules from the source tree will be used (rather than those installed on the
+system). In order to avoid certain types of failures you will need to ensure
+the ZFS udev rules are installed. This can be done manually or by ensuring
+some version of ZFS is installed on the system.
+
+ $ ./scripts/zfs-tests.sh
+
+The following zfs-tests.sh options are supported:
+
+ -v Verbose zfs-tests.sh output When specified additional
+ information describing the test environment will be logged
+ prior to invoking test-runner. This includes the runfile
+ being used, the DISKS targeted, pools to keep, etc.
+
+ -q Quiet test-runner output. When specified it is passed to
+ test-runner(1) which causes output to be written to the
+ console only for tests that do not pass and the results
+ summary.
+
+ -x Remove all testpools, dm, lo, and files (unsafe). When
+ specified the script will attempt to remove any leftover
+ configuration from a previous test run. This includes
+ destroying any pools named testpool, unused DM devices,
+ and loopback devices backed by file-vdevs. This operation
+ can be DANGEROUS because it is possible that the script
+ will mistakenly remove a resource not related to the testing.
+
+ -k Disable cleanup after test failure. When specified the
+ zfs-tests.sh script will not perform any additional cleanup
+ when test-runner exists. This is useful when the results of
+ a specific test need to be preserved for further analysis.
+
+ -f Use sparse files directly instread of loopback devices for
+ the testing. When running in this mode certain tests will
+ be skipped which depend on real block devices.
+
+ -d DIR Create sparse files for vdevs in the DIR directory. By
+ default these files are created under /var/tmp/.
+
+ -s SIZE Use vdevs of SIZE (default: 2G)
+
+ -r RUNFILE Run tests in RUNFILE (default: linux.run)
+
+
+The ZFS Test Suite allows the user to specify a subset of the tests via a
+runfile. The format of the runfile is explained in test-runner(1), and
+the files that zfs-tests.sh uses are available for reference under
+/usr/share/zfs/runfiles. To specify a custom runfile, use the -r option:
+
+ $ /usr/share/zfs/zfs-tests.sh -r my_tests.run
+
+3) Test results
+
+While the ZFS Test Suite is running, one informational line is printed at the
+end of each test, and a results summary is printed at the end of the run. The
+results summary includes the location of the complete logs, which is logged in
+the form /var/tmp/test_results/[ISO 8601 date]. A normal test run launched
+with the `zfs-tests.sh` wrapper script will look something like this:
+
+$ /usr/share/zfs/zfs-tests.sh -v -d /mnt

+.fi
+
+.SH DESCRIPTION
+.sp
+.LP
+The \fBrun\fR command has three basic modes of operation. With neither the
+\fB-c\fR nor the \fB-w\fR option, \fBrun\fR processes the arguments provided on
+the command line, adding them to the list for this run. If a specified
+\fIpathname\fR is an executable file, it is added as a test. If a specified
+\fIpathname\fR is a directory, the behavior depends upon the \fB-g\fR option.
+If \fB-g\fR is specified, the directory is treated as a test group. See the
+section on "Test Groups" below. Without the \fB-g\fR option, \fBrun\fR simply
+descends into the directory looking for executable files. The tests are then
+executed, and the results are logged.
+
+With the \fB-w\fR option, \fBrun\fR finds tests in the manner described above.
+Rather than executing the tests and logging the results, the test configuration
+is stored in a \fIrunfile\fR which can be used in future invocations, or edited
+to modify which tests are executed and which options are applied. Options
+included on the command line with \fB-w\fR become defaults in the
+\fIrunfile\fR.
+
+With the \fB-c\fR option, \fBrun\fR parses a \fIrunfile\fR, which can specify a
+series of tests and test groups to be executed. The tests are then executed,
+and the results are logged.
+.sp
+.SS "Test Groups"
+.sp
+.LP
+A test group is comprised of a set of executable files, all of which exist in
+one directory. The options specified on the command line or in a \fIrunfile\fR
+apply to individual tests in the group. The exception is options pertaining to
+pre and post scripts, which act on all tests as a group. Rather than running
+before and after each test, these scripts are run only once each at the start
+and end of the test group.
+.SS "Test Execution"
+.sp
+.LP
+The specified tests run serially, and are typically assigned results according
+to exit values. Tests that exit zero and non-zero are marked "PASS" and "FAIL"
+respectively. When a pre script fails for a test group, only the post script is
+executed, and the remaining tests are marked "SKIPPED." Any test that exceeds
+its \fItimeout\fR is terminated, and marked "KILLED."
+
+By default, tests are executed with the credentials of the \fBrun\fR script.
+Executing tests with other credentials is done via \fBsudo\fR(1m), which must
+be configured to allow execution without prompting for a password. Environment
+variables from the calling shell are available to individual tests. During test
+execution, the working directory is changed to \fIoutputdir\fR.
+.SS "Output Logging"
+.sp
+.LP
+By default, \fBrun\fR will print one line on standard output at the conclusion
+of each test indicating the test name, result and elapsed time. Additionally,
+for each invocation of \fBrun\fR, a directory is created using the ISO 8601
+date format. Within this directory is a file named \fIlog\fR containing all the
+test output with timestamps, and a directory for each test. Within the test
+directories, there is one file each for standard output, standard error and
+merged output. The default location for the \fIoutputdir\fR is
+\fI/var/tmp/test_results\fR.
+.SS "Runfiles"
+.sp
+.LP
+The \fIrunfile\fR is an ini style configuration file that describes a test run.
+The file has one section named "DEFAULT," which contains configuration option
+names and their values in "name = value" format. The values in this section
+apply to all the subsequent sections, unless they are also specified there, in
+which case the default is overridden. The remaining section names are the
+absolute pathnames of files and direcotries, describing tests and test groups
+respectively. The legal option names are:

+# DESCRIPTION:
+# Sanity test to make sure checksum algorithms work.
+# For each checksum, create a file in the pool using that checksum. Verify
+# that there are no checksum errors. Next, for each checksum, create a single
+# file in the pool using that checksum, scramble the underlying vdev, and
+# verify that we correctly catch the checksum errors.
+#
+# STRATEGY:
+# Test 1
+# 1. Create a mirrored pool
+# 2. Create a file using each checksum
+# 3. Export/import/scrub the pool
+# 4. Verify there's no checksum errors.
+# 5. Clear the pool
+#
+# Test 2
+# 6. For each checksum:
+# 7. Create a file using the checksum
+# 8. Export the pool
+# 9. Scramble the data on one of the underlying VDEVs
+# 10. Import the pool
+# 11. Scrub the pool
+# 12. Verify that there are checksum errors

+# DESCRIPTION
+# Verify zfs destroy test for range of snapshots by giving a list
+# of valid and invalid arguments.
+
+# STRATEGY
+# 1. Create a list of valid and invalid arguments for range snapshot
+# destroy.
+# 2. Set up a filesystem and a volume with multiple snapshots
+# 3. Run zfs destroy for all the arguments and verify existence of snapshots
+# 4. Verify the destroy for snapshots with clones and hold

+# DESCRIPTION:
+# Once a pool has been exported, and one or more devices are
+# damaged or missing (d/m), import should handle this kind of situation
+# as described:
+# - Regular, report error while any number of devices failing.
+# - Mirror could withstand (N-1) devices failing
+# before data integrity is compromised
+# - Raidz could withstand one devices failing
+# before data integrity is compromised
+# Verify those are true.
+#
+# STRATEGY:
+# 1. Create test pool upon device files using the various combinations.
+# - Regular pool
+# - Mirror
+# - Raidz
+# 2. Create necessary filesystem and test files.
+# 3. Export the test pool.
+# 4. Remove one or more devices
+# 5. Verify 'zpool import' will handle d/m device successfully.
+# Using the various combinations.
+# - Regular import
+# - Alternate Root Specified
+# It should be succeed with single d/m device upon 'raidz' & 'mirror',
+# but failed against 'regular' or more d/m devices.
+# 6. If import succeed, verify following is true:
+# - The pool shows up under 'zpool list'.
+# - The pool's health should be DEGRADED.
+# - It contains the correct test file

+# The configX.cfg files describe both the dataset hierarchy to

+# properties, i.e. whether they should be left with their default values
+# or set locally.
+#
+# Format for this file is as follows:
+# <dataset name> <dataset type> <inital property setting>
+#
+# <dataset name> - must be the full dataset name
+#
+# <dataset type> - recognised types are POOL, CTR and FS
+#
+#
+# <initial property setting> - can have one of the following
+# values:
+#
+# default property values are left unchanged
+#
+# local property values are set locally
+#
+# - property values are left unchanged (has the
+# same effect as 'default' but is used to indicate
+# that the property 'source' field may be 'inherited
+# from..' depending on the actions further up the
+# dataset hierarchy.
+#
+#
+# The configuration below creates a three tier dataset layout, consisting
+# of a pool, container and filesystem.
+#
+# The top tier pool's properties being set locally, and the two
+# lower tier properties each inheriting their values from the next tier

+# For every configX.cfg file there must be a corresponding stateX.cfg
+# file. The state file both drives the operations to be performed on the
+# dataset hierarchy which has been specified by the corresponding
+# configX.cfg file, and also specifies the expected state of the
+# properties after the operation has been completed.
+#
+# The format of the file is:
+# <target dataset>:<command>
+# <property source before command> <property src after command>
+# <property source before command> <property src after command>
+# .... ....
+# .... ....
+#
+# <target dataset> - dataset upon which the <command> is to be executed. Can
+# be any of the datasets specified in the corresponding
+# configX.cfg file. If no command is to be executed
+# then must be set to '-'
+#
+#
+# <command> - command to be executed upon the specified dataset.
+# Currently the only supported commands are 'inherit'
+# or 'inherit -r'. If no command is to be executed,
+# then must be set to '-'.
+#
+# <property src before command>
+# - the 'source' (as reported in 'zfs get') for the
+# the properties before <command> is executed. This
+# can be 'default', 'local' or the name of a dataset
+# from which the property is inherited. (The code
+# automatically adds in the 'inherited from..' part
+# of the string when doing the check.
+#
+# This field is for informational purposes only, to
+# aid the user in seeing how the changes trickle down
+# the data hierarchy.
+#
+# <property src after command>
+# - the expected value of the 'source' field after the
+# <command> has been executed on the <target dataset>.
+# As above can be 'default', 'local', or the dataset
+# from which the property is inherited.
+#
+# Two important things to note:
+# 1) there must be a <property src..> line corresponding to each dataset
+# line specified in the configX.cfg file.
+#
+#
+# 2) There can be as many <command>/<property src> blocks as desired, but
+# there must be at least one, and the effect of each block is cumulative
+# (i.e. the properties are not reset back to their default values between
+# each block. If that is desired then each block must be placed in its
+# own state file with its own corresponding configX.cfg file).
+#
+#
+# Below are two sample <command>/<property src> blocks.
+#
+# The first simply verifies that the properties on the top level dataset
+# were set locally, and that the middle and bottom datasets properties
+# were inherited from the top level pool (called TESTPOOL). Note the '-:-'
+# which means that no command is to be executed, but simply that the
+# properties settings are to be verified.

+# down the hierarchy, the value at each level is determined by a combination
+# of the top-level value and the current level in the hierarchy.

+# mountpoint of the pool to '/mnt2' then the mountpoints for the dataset and
+# filesystem are '/mnt2/ctr' and /mnt2/ctr/fs' respectively, with the 'source'
+# field being set to 'inherited from pool1'.
+#
+# So at the filesystem level to calculate what our mountpoint property should
+# be set to we walk back up the hierarchy sampling the mountpoint property at
+# each level and forming up the expected mountpoint value piece by piece until
+# we reach the level specified in the 'source' field, which in this example is

+# Make a best approximation by calling umountall with the -n option, and verify
+# that the list of things it would try to unmout makes sense.
+#
+# STRATEGY:
+# 1. Make a list of file systems umountall is known to ignore.
+# 2. Append all ZFS file systems on this system.
+# 3. Run umountall -n and verify the file systems it reports are in the list.
