Ned Bass 36ccb9db43 vdev_id: fix failure due to multipath -l bug
Udev may fail to create the expected symbolic links in
/dev/disk/by-vdev on systems with the
device-mapper-multipath-0.4.9-100.el6 package installed. This affects
RHEL 6.9 and possibly other downstream distributions.

That version of the multipath command may incorrectly list a drive
state as "unkown" instead of "running". The issue was introduced
in the patch for https://bugzilla.redhat.com/show_bug.cgi?id=1401769

The vdev_id udev helper uses the state reported by "multipath -l" to
detect an online component disk of a multipath device in order to
resolve its physical slot and enclosure. Changing the command
invocation to "multipath -ll" works around the above issue by causing
multipath to consult additional sources of information to determine
the drive state.

Brian Behlendorf 2cb77346cb Use udev for partition detection
When ZFS partitions a block device it must wait for udev to create
both a device node and all the device symlinks.  This process takes
a variable length of time and depends on factors such how many links
must be created, the complexity of the rules, etc.  Complicating
the situation further it is not uncommon for udev to create and
then remove a link multiple times while processing the udev rules.

Given the above, the existing scheme of waiting for an expected
partition to appear by name isn't 100% reliable.  At this point
udev may still remove and recreate think link resulting in the
kernel modules being unable to open the device.

In order to address this the zpool_label_disk_wait() function
has been updated to use libudev.  Until the registered system
device acknowledges that it in fully initialized the function
will wait.  Once fully initialized all device links are checked
and allowed to settle for 50ms.  This makes it far more likely
that all the device nodes will exist when the kernel modules
need to open them.

For systems without libudev an alternate zpool_label_disk_wait()
was updated to include a settle time.  In addition, the kernel
modules were updated to include retry logic for this ENOENT case.
Due to the improved checks in the utilities it is unlikely this
logic will be invoked.  However, if the rare event it is needed
it will prevent a failure.

Brian Behlendorf fbffa53a5c Create unique partition labels
When partitioning a device a name may be specified for each partition.
Internally zfs doesn't use this partition name for anything so it
has always just been set to "zfs".

However this isn't optimal because udev will create symlinks using
this name in /dev/disk/by-partlabel/.  If the name isn't unique
then all the links cannot be created.

Therefore a random 64-bit value has been added to the partition
label, i.e "zfs-1234567890abcdef".  Additional information could
be encoded here but since partitions may be reused that might
result in confusion and it was decided against.

Richard Yao eb02072279 Add -gLp to zpool subcommands for alt vdev names
The following options have been added to the zpool add, iostat,
list, status, and split subcommands.  The default behavior was
not modified, from zfs(8).

  -g    Display vdev GUIDs  instead  of  the  normal  short
        device  names.  These GUIDs can be used in-place of
        device   names   for    the    zpool    detach/off‐
        line/remove/replace commands.

  -L    Display real paths for vdevs resolving all symbolic
        links. This can be used to lookup the current block
        device  name regardless of the /dev/disk/ path used
        to open it.

  -p    Display  full  paths  for vdevs instead of only the
        last component of the path.  This can  be  used  in
        conjunction with the -L flag.

This behavior may also be enabled using the following environment
variables.

  ZPOOL_VDEV_NAME_GUID
  ZPOOL_VDEV_NAME_FOLLOW_LINKS
  ZPOOL_VDEV_NAME_PATH

This change is based on worked originally started by Richard Yao
to add a -g option.  Then extended by @ilovezfs to add a -L option
for openzfsonosx.  Those changes have been merged, re-factored,
a -p option added and extended to all relevant zpool subcommands.

mount.zfs is called by convention (and util-linux) with arguments
last, i.e.

  % mount.zfs <dataset> <mountpoint> -o <options>

This is not a problem on glibc since GNU getopt(3) will reorder the
arguments.  However, alternative libc such as musl libc (or glibc with
$POSIXLY_CORRECT set) will not permute argv and fail to parse the -o
<options>.  Use getopt_long so musl will permute arguments.

Ned Bass 4f07f6086e Honor xattr=sa dataset property
ZFS incorrectly uses directory-based extended attributes even when
xattr=sa is specified as a dataset property or mount option. Support to
honor temporary mount options including "xattr" was added in commit
0282c4137e. There are two issues with the
mount option handling:

* Libzfs has historically included "xattr" in its list of default mount
  options. This overrides the dataset property, so the dataset is always
  configured to use directory-based xattrs even when the xattr dataset
  property is set to off or sa. Address this by removing "xattr" from
  the set of default mount options in libzfs.

* There was no way to enable system attribute-based extended attributes
  using temporary mount options. Add the mount options "saxattr" and
  "dirxattr" which enable the xattr behavior their names suggest.  This
  approach has the advantages of mirroring the valid xattr dataset
  property values and following existing conventions for mount option
  names.

the log is disabled, to enable it set zfs_dbgmsg_enable=1.  The contents
of the log can be accessed by reading the /proc/spl/kstat/zfs/dbgmsg file.
Writing 0 to this proc file clears the log.

$ echo 1 >/sys/module/zfs/parameters/zfs_dbgmsg_enable
$ echo 0 >/proc/spl/kstat/zfs/dbgmsg
$ zpool import tank

Turbo Fredriksson 47a4a6fd5f Support parallel build trees (VPATH builds)
Build products from an out of tree build should be written
relative to the build directory.  Sources should be referred
to by their locations in the source directory.

This is accomplished by adding the 'src' and 'obj' variables
for the module Makefile.am, using relative paths to reference
source files, and by setting VPATH when source files are not
co-located with the Makefile.  This enables the following:

  $ mkdir build
  $ cd build
  $ ../configure \
    --with-spl=$HOME/src/git/spl/ \
    --with-spl-obj=$HOME/src/git/spl/build
  $ make -s

This change also has the advantage of resolving the following

Porting notes and other significant code changes:

The illumos 5368 patch (ARC should cache more metadata), which
was never picked up by ZoL, is mostly reverted by this patch.

Since ZoL relies on the kernel asynchronously calling the shrinker to
actually reap memory, the shrinker wakes up arc_reclaim_waiters_cv every
time it runs.

The arc_adapt_thread() function no longer calls arc_do_user_evicts()
since the newly-added arc_user_evicts_thread() calls it periodically.

Notable conflicting ZoL commits which conflicted with this patch or
whose effects are either duplicated or un-done by this patch:

    302f753 - Integrate ARC more tightly with Linux
    39e055c - Adjust arc_p based on "bytes" in arc_shrink
    f521ce1 - Allow "arc_p" to drop to zero or grow to "arc_c"
    77765b5 - Remove "arc_meta_used" from arc_adjust calculation
    94520ca - Prune metadata from ghost lists in arc_adjust_meta

Trace support for multilist_insert() and multilist_remove() has been
added and produces the following output:

    fio-12498 [077] .... 112936.448324: zfs_multilist__insert: ml { offset 240 numsublists 80 sublistidx 63 }
    fio-12498 [077] .... 112936.448347: zfs_multilist__remove: ml { offset 240 numsublists 80 sublistidx 29 }

The following arcstats have been removed:

    recycle_miss - Used by arcstat.py and arc_summary.py, both of which
    have been updated appropriately.

    l2_writes_hdr_miss

The following arcstats have been added:

    evict_not_enough - Number of times arc_evict_state() was unable to
    evict enough buffers to reach its target amount.

    evict_l2_skip - Number of times arc_evict_hdr() skipped eviction
    because it was being written to the l2arc.

    l2_writes_lock_retry - Replaces l2_writes_hdr_miss.  Number of times
    l2arc_write_done() failed to acquire hash_lock (and re-tries).

    arc_meta_min - Shows the value of the zfs_arc_meta_min module
    parameter (see below).

The "index" column of the "dbuf" kstat has been removed since it doesn't
have a direct analog in the new multilist scheme.  Additional multilist-
related stats could be added in the future but would likely require
extensions to the mulilist API.

The following module parameters have been added:

    zfs_arc_evict_batch_limit - Number of ARC headers to free per sub-list
    before moving on to the next sub-list.

    zfs_arc_meta_min - Enforce a floor on the amount of metadata in
    the ARC.

    zfs_arc_num_sublists_per_state - Number of multilist sub-lists per
    ARC state.

Porting notes:

Due to the restructuring of the ARC-related structures, this
patch conflicts with at least the following existing ZoL commits:

    6e1d7276c9
    Fix inaccurate arcstat_l2_hdr_size calculations

        The ARC_SPACE_HDRS constant no longer exists and has been
        somewhat equivalently replaced by HDR_L2ONLY_SIZE.

    e0b0ca983d
    Add visibility in to cached dbufs

        The new layering of l{1,2}arc_buf_hdr_t within the arc_buf_hdr
        struct requires additional structure member names to be used
        when referencing the inner items.  Also, the presence of L1 or L2
        inner member is indicated by flags using the new HDR_HAS_L{1,2}HDR
        macros.

Chris Dunlap 492b1d2ef0 Update ZED copyright boilerplate
This commit updates the copyright boilerplate within the ZED subtree.

The instructions for appending a contributor copyright line have
been removed.  Manually maintaining copyright notices in this
manner is error-prone, imprecise at a file-scope granularity, and
oftentimes inaccurate.  These lines can become a pernicious source of
merge conflicts.  A commit log is better suited to maintaining this
information.  Consequently, a line has been added to the boilerplate
to refer to the git commit log for authoritative copyright attribution.

To account for the scenario where a file may become separated from
the codebase and commit history (i.e., it is copied somewhere else),
a line has been added to identify the file's origin.

Porting Notes:

* Included in this patch is a tiny ISP2() cleanup in zio_init() from
Illumos 5255.

* Unlike the upstream Illumos commit this patch does not impose an
arbitrary 128K block size limit on volumes.  Volumes, like filesystems,
are limited by the zfs_max_recordsize=1M module option.

* By default the maximum record size is limited to 1M by the module
option zfs_max_recordsize.  This value may be safely increased up to
16M which is the largest block size supported by the on-disk format.
At the moment, 1M blocks clearly offer a significant performance
improvement but the benefits of going beyond this for the majority
of workloads are less clear.

* The illumos version of this patch increased DMU_MAX_ACCESS to 32M.
This was determined not to be large enough when using 16M blocks
because the zfs_make_xattrdir() function will fail (EFBIG) when
assigning a TX.  This was immediately observed under Linux because
all newly created files must have a security xattr created and
that was failing.  Therefore, we've set DMU_MAX_ACCESS to 64M.

* On 32-bit platforms a hard limit of 1M is set for blocks due
to the limited virtual address space.  We should be able to relax
this one the ABD patches are merged.

Chris Dunlap ce119da33d Combine data-notify.sh with io-notify.sh
The data-notify.sh ZEDLET serves a very similar purpose to
io-notify.sh, namely, to generate a notification in response to a
particular error event.  Initially, data-notify.sh was separated from
io-notify.sh since the "data" zevent does not (as I understand it)
pertain to a specific vdev device.  This stands in contrast to the
"checksum" and "io" zevents (both handled by io-notify.sh) that can
be attributed to a specific vdev.  At the time, it seemed simpler to
handle these two cases in separate scripts.

This commit adds support for the "data" zevent to io-notify.sh, and
symlinks io-notify.sh to data-notify.sh.  It also adds the counts
for vdev_read_errors, vdev_write_errors, and vdev_cksum_errors to
the notification message.

Chris Dunlap a0d065fa92 Add support for Pushbullet notifications
This commit adds the zed_notify_pushbullet() function and hooks
it into zed_notify(), thereby integrating it with the existing
"notify" ZEDLETs.  This enables ZED to push notifications to your
desktop computer and/or mobile device(s).  It is configured with the
ZED_PUSHBULLET_ACCESS_TOKEN and ZED_PUSHBULLET_CHANNEL_TAG variables
in zed.rc.

  https://www.pushbullet.com/

The Makefile install-data-local target has been replaced with
install-data-hook.  With the "-local" target, there is no particular
guarantee of execution order.  But with the zed.rc now potentially
containing sensitive information (i.e., the Pushbullet access token),
the recommended permissions have changed to 0600.  The "-hook" target
is always executed after the main rule's work is done; thus, the
chmod will always take place after the zed.rc file has been installed.
