Ryan Moeller 2f65c7a608 FreeBSD: Define crgetzoneid appropriately
The previous ZFS implementation on FreeBSD had ifdefs to use jailed()
instead of crgetzoneid() in dsl_dir.c, however we can simply provide an
appropriate definition of crgetzoneid for the same effect.

Linux 5.9 compat: NR_SLAB_RECLAIMABLE
Commit dcdc12e added compatibility code to treat NR_SLAB_RECLAIMABLE_B
as if it were the same as NR_SLAB_RECLAIMABLE.  However, the new value
is in bytes while the old value was in pages which means they are not
interchangeable.

The only place the reclaimable slab size is used is as a component of
the calculation done by arc_free_memory().  This function returns the
amount of memory the ARC considers to be free or reclaimable at little
cost.  Rather than switch to a new interface to get this value it has
been removed it from the calculation.  It is normally a minor component
compared to the number of inactive or free pages, and removing it
aligns the behavior with the FreeBSD version of arc_free_memory().

Richard Laager 62663fb7ec Fix another dependency loop
zfs-load-key-DATASET.service was gaining an
After=systemd-journald.socket due to its stdout/stderr going to the
journal (which is the default).  systemd-journald.socket has an After
(via RequiresMountsFor=/run/systemd/journal) on -.mount.  If the root
filesystem is encrypted, -.mount gets an After
zfs-load-key-DATASET.service.

By setting stdout and stderr to null on the key load services, we avoid
this loop.

config/zfs-build.m4: add --with-vendor flag
This will allow an override of auto-detection of distribution, which
is based on checking presence of /etc/*-release files.

Build systems makes a lot of file location assumptions based on
detected distribution.

Some distributions (like gentoo) may prefer explicitly
setting --with-vendor=gentoo to avoid auto-detection.

Since auto-detection checks all files in order, current script may
misdetect even on gentoo system if /etc/redhat-release file is present

Default behavior is unchanged and default is --with-vendor=check

If kernel is compiled with -march=znver1 or -march=znver2 zstd module 
compilation will fail due to SSE register return with SSE disabled.
What's interesting, is that -march=skylake also implies -mbmi which 
defines __BMI__ but compilation succeeds.  It is probably due to 
different BMI implementations on AMD and INTEL processors and the 
way compiler uses instructions.

Because dnode_sync_free_range() must drop dn_mtx during its processing,
using it as a callback to range_tree_vacate() is not safe.  No other
operations (besides destroy) are allowed once range_tree_vacate() has

Paul Dagnelie 4aa3b3bd47
Always track temporary fses and snapshots for accounting
The root cause of the issue is that we only occasionally do as the 
comments in the code suggest and actually ignore the %recv dataset when 
it comes to filesystem limit tracking. Specifically, the only time we 
ignore it is when initializing the filesystem and snapshot limit values; 
when creating a new %recv dataset or deleting one, we always update 
the bookkeeping. This causes a problem if you init the fs count on a 
filesystem that already has a %recv dataset, since the bookmarking 
will be decremented but not incremented. This is resolved in this 
patch by simply always tracking the %recv dataset as a child.

Introduce limit on size of L2ARC headers
Since L2ARC buffers are not evicted on memory pressure, too large
amount of headers on system with irrationally large L2ARC can render
it slow or even unusable.  This change limits L2ARC writes and
rebuild if unevictable L2ARC-only headers reach dangerous level.

While there, call arc_adapt() on L2ARC rebuild, so that it could
properly grow arc_c, reflecting potentially significant ARC size
increase and avoiding slow growth with hopeless eviction attempts
later when "overflow" is detected.

Don't assert on nvlists larger than SPA_MAXBLOCKSIZE

However, nvlists are not ZFS records, and are not limited to

Add a new environment variable, ZFS_SENDRECV_MAX_NVLIST, to allow the
user to specify the maximum size of the nvlist that can be sent or
received.
Default value: 4 * SPA_MAXBLOCKSIZE (64 MB)

Modify libzfs send routines to return a useful error if the send stream
will generate an nvlist that is beyond the maximum size.

Modify libzfs recv routines to add an explicit error message if the
nvlist is too large, rather than abort()ing.

Prevent zfs_acl_chmod() if aclmode restricted and ACL inherited
In absence of inheriting entry for owner@, group@, or everyone@,
zfs_acl_chmod() is called to set these. This can cause confusion for Samba
admins who do not expect these entries to appear on newly created files and
directories once they have been stripped from from the parent directory.

When aclmode is set to "restricted", chmod is prevented on non-trivial ACLs.
It is not a stretch to assume that in this case the administrator does not want
ZFS to add the missing special entries. Add check for this aclmode, and if an
inherited entry is present skip zfs_acl_chmod().

Make formatting of dedup values string consistent

dedup values do not, they are separated by `, `. This change

Import vdev ashift optimization from FreeBSD
Many modern devices use physical allocation units that are much
larger than the minimum logical allocation size accessible by
external commands. Two prevalent examples of this are 512e disk
drives (512b logical sector, 4K physical sector) and flash devices
(512b logical sector, 4K or larger allocation block size, and 128k
or larger erase block size). Operations that modify less than the
physical sector size result in a costly read-modify-write or garbage
collection sequence on these devices.

Simply exporting the true physical sector of the device to ZFS would
yield optimal performance, but has two serious drawbacks:

 1. Existing pools created with devices that have different logical
    and physical block sizes, but were configured to use the logical
    block size (e.g. because the OS version used for pool construction
    reported the logical block size instead of the physical block
    size) will suddenly find that the vdev allocation size has
    increased. This can be easily tolerated for active members of
    the array, but ZFS would prevent replacement of a vdev with
    another identical device because it now appears that the smaller
    allocation size required by the pool is not supported by the new
    device.

 2. The device's physical block size may be too large to be supported
    by ZFS. The optimal allocation size for the vdev may be quite
    large. For example, a RAID controller may export a vdev that
    requires read-modify-write cycles unless accessed using 64k
    aligned/sized requests. ZFS currently has an 8k minimum block
    size limit.

Reporting both the logical and physical allocation sizes for vdevs
solves these problems. A device may be used so long as the logical
block size is compatible with the configuration. By comparing the
logical and physical block sizes, new configurations can be optimized
and administrators can be notified of any existing pools that are
sub-optimal.

Remove hard coded "Linux" OS from manpages
The recommended practice for `.Os` on FreeBSD is to not specify any
arguments.  The correct OS name is used automatically.

Oddly enough, on the Linux distro I tested this on (CentOS 7), the man
pager defaulted to displaying "BSD" as the OS rather than "Linux".  To
accommodate this, tack " Linux" back on in an install hook on Linux.
This is much simpler than removing it for FreeBSD when vendored in the
base system.

Silence 'make checkbashisms'
Commit d2bce6d03 added the 'make checkbashisms' target but did not
resolve all of the bashisms in the scripts.  This commit doesn't
resolve them all either but it does fix up a few, and it excludes
the others so 'make checkstyle' no longer prints warnings.  It's
a small step in the right direction.

* Dracut is Linux specific and itself depends on bash.  Therefore
  all dracut support scripts can be bash specific, update their
  shebang accordingly.

* zed-functions.sh, zfs-import, zfs-mount, zfs-zed, smart
  paxcheck.sh, make_gitrev.sh - these scripts were excuded from
  the check until they can be updated and properly tested.

* zfsunlock - only whole values for sleep are allowed.

* vdev_id - removed unneeded locals; use && instead of -a.

* dkms.mkconf, dkms.postbuil - use || instead of -o.

'zfs share -a' should clean noauto exports
This is a follow on to PR #10688 where `zfs share -a` allows the 
sharing of canmount=noauto datasets if they are mounted.  However, 
when a dataset with canmount=noauto is not mounted, the command 
should also purge any existing entries from the exports file. 
Otherwise, after a reboot, the nfs server attempts to export the 
underlying mountpath, not the dataset. This can lead to a hard hang 
for existing client mounts.

Instead of just skipping the adding of an export if not mounted 
and canmount=noauto, have it also remove an existing export of the 
dataset so that, after a reboot, we don't export an unmounted dataset.
