libzutil is currently statically linked into libzfs, libzfs_core and
libzpool. Avoid the unnecessary duplication by removing it from libzfs
and libzpool, and adding libzfs_core to libzpool.
Remove a few unnecessary dependencies:
- libuutil from libzfs_core
- libtirpc from libspl
- keep only libcrypto in libzfs, as we don't use any functions from
libssl
- librt is only used for clock_gettime, however on modern systems that's
in libc rather than librt. Add a configure check to see if we actually
need librt
- libdl from raidz_test
Add a few missing dependencies:
- zlib to libefi and libzfs
- libuuid to zpool, and libuuid and libudev to zed
- libnvpair uses assertions, so add assert.c to provide aok and
libspl_assertf
Sort the LDADD for programs so that libraries that satisfy dependencies
come at the end rather than the beginning of the linker command line.
Revamp the configure tests for libaries to use FIND_SYSTEM_LIBRARY
instead. This can take advantage of pkg-config, and it also avoids
polluting LIBS.
List all the required dependencies in the pkgconfig files, and move the
one for libzfs_core into the latter's directory. Install pkgconfig files
in $(libdir)/pkgconfig on linux and $(prefix)/libdata/pkgconfig on
FreeBSD, instead of /usr/share/pkgconfig, as the more correct location
for library .pc files.

FreeBSD recently replaced the GNU bc and dc in the base system with
BSD licensed versions. They are supposed to be compatible with all
the features present in the GNU versions, but it turns out they are
picky about `if` statements having a corresponding `else`. ZTS uses
`echo "if ($x > $y) 1" | bc` in a few places, which causes tests to
fail unexpectedly with the new bc.
Change the two expressions in ZTS to `if ($x > $y) 1 else 0` for
compatibility with the new BSD bc.

The device_rebuild feature enables sequential reconstruction when
resilvering. Mirror vdevs can be rebuilt in LBA order which may
more quickly restore redundancy depending on the pools average block
size, overall fragmentation and the performance characteristics
of the devices. However, block checksums cannot be verified
as part of the rebuild thus a scrub is automatically started after
the sequential resilver completes.
The new '-s' option has been added to the `zpool attach` and
`zpool replace` command to request sequential reconstruction
instead of healing reconstruction when resilvering.
zpool attach -s <pool> <existing vdev> <new vdev>
zpool replace -s <pool> <old vdev> <new vdev>
The `zpool status` output has been updated to report the progress
of sequential resilvering in the same way as healing resilvering.
The one notable difference is that multiple sequential resilvers
may be in progress as long as they're operating on different
top-level vdevs.
The `zpool wait -t resilver` command was extended to wait on
sequential resilvers. From this perspective they are no different
than healing resilvers.
Sequential resilvers cannot be supported for RAIDZ, but are
compatible with the dRAID feature being developed.
As part of this change the resilver_restart_* tests were moved
in to the functional/replacement directory. Additionally, the
replacement tests were renamed and extended to verify both
resilvering and rebuilding.

OS-specific code (e.g. under `module/os/linux`) does not need to share
its code structure with any other operating systems. In particular, the
ARC and kmem code need not be similar to the code in illumos, because we
won't be syncing this OS-specific code between operating systems. For
example, if/when illumos support is added to the common repo, we would
add a file `module/os/illumos/zfs/arc_os.c` for the illumos versions of
this code.
Therefore, we can simplify the code in the OS-specific ARC and kmem
routines.
These changes do not impact system behavior, they are purely code
cleanup. The changes are:
Arenas are not used on Linux or FreeBSD (they are always `NULL`), so
`heap_arena`, `zio_arena`, and `zio_alloc_arena` can be removed, along
with code that uses them.
In `arc_available_memory()`:
* `desfree` is unused, remove it
* rename `freemem` to avoid conflict with pre-existing `#define`
* remove checks related to arenas
* use units of bytes, rather than converting from bytes to pages and
then back to bytes

`skc_reap` is unused, remove it.

The SPL provides a wrapper for the kernel's shrinker callbacks, which
enables the ZFS code to interface with multiple versions of the shrinker
API's from different kernel versions. Specifically, Linux kernels 3.0 -
3.11 has a single "combined" callback, and Linux kernels 3.12 and later
have two "split" callbacks. The SPL provides a wrapper function so that
the ZFS code only needs to implement one version of the callbacks.
Currently the SPL's wrappers are designed such that the ZFS code
implements the older, "combined" callback. There are a few downsides to
this approach:
* The general design within ZFS is for the latest Linux kernel to be
considered the "first class" API.
* The newer, "split" callback API is easier to understand, because each
callback has one purpose.
* The current wrappers do not completely abstract out the differing
API's, so ZFS code needs `#ifdef` code to handle the differing return
values required for different kernel versions.
This commit addresses these drawbacks by having the ZFS code provide the
latest, "split" callbacks, and the SPL provides a wrapping function for
the older, "combined" API.

ZFS registers a memory hook, `__arc_shrinker_func`, which is supposed to
allow the ARC to shrink when the kernel experiences memory pressure.
The ARC shrinker changes `arc_c` via a call to
`arc_reduce_target_size()`. Before commit 3ec34e5527, the ARC
shrinker would also evict data from the ARC to bring `arc_size` down to
the new `arc_c`. However, that commit (seemingly inadvertently) made it
so that the ARC shrinker no longer evicts any data or waits for eviction
to complete.
Repeated calls to the ARC shrinker can reduce `arc_c` drastically, often
all the way to `arc_c_min`. Since it doesn't wait for the actual
eviction of data from the ARC, this creates a situation where `arc_size`
is more than `arc_c` for the several seconds/minutes it takes for
`arc_adjust_zthr` to evict data from the ARC. During this time,
arc_get_data_impl() will block, so ZFS can't process read/write requests
(e.g. from iSCSI, NFS, or read/write syscalls).
To ensure that `arc_c` doesn't shrink faster than the adjust thread can
keep up, this commit makes the ARC shrinker wait for the eviction to
complete, resulting in similar behavior to what we had before commit
3ec34e5527.
Note: commit 3ec34e5527 is `OpenZFS 9284 - arc_reclaim_thread
has 2 jobs` and was integrated in December 2018, and is part of ZoL
0.8.x but not 0.7.x.
Additionally, when the ARC size is reduced drastically, the
`arc_adjust_zthr` can be on-CPU for many seconds without blocking. Any
threads that are bound to the same CPU that arc_adjust_zthr is running
on will not able to run for a long time.
To ensure that CPU-bound threads can make progress, this commit changes
`arc_evict_state_impl()` make a voluntary preemption call,
`cond_resched()`.

target is pointless anyway, and gtags is not a recursive target.
Fix cscopelist by moving it to the top-level Makefile as well, in line
with ctags and etags.
Also, add -a to ctags command as well, otherwise it won't work if more
than one xargs invocation takes place.
Add assembler files to ctags/etags, prune all dotted-dirs, and restrict
the find to files only.
Cleanup: add .PHONY to module/Makefile.in, and fix one recipe with a
missing continuation character.

Currently, asm-generic/atomic.c is compiled into a .S file, with a
comment saying this is to simplify the upper-level Makefile.
However, this doesn't work properly with a VPATH build, which would
require better logic to deal with generated sources correctly.
It also doesn't seem more complex to just specify the .c/.S source file,
depending on the cpu, instead of only the source directory in
lib/libspl/Makefile.am, which eliminates the need to do the intermediate
compilation.

Currently an out-of-tree build does not work with read-only source
directory because zfs_gitrev.h can't be created. Move this file to the
build directory, which is more appropriate for a generated file, and
drop the dist-hook for zfs_gitrev.h. There is no need to distribute this
file since it will be regenerated as part of the compilation in any
case.
scripts/make_gitrev.sh tries to avoid updating zfs_gitrev.h if there has
been no change, however this doesn't cover the case when the source
directory is not in git: in that case zfs_gitrev.h gets overwritten even
though it's always "unknown". Simplify the logic to always write out a
new version of zfs_gitrev.h, compare against the old and overwrite only
if different. This is now simple enough to just include in the
Makefile, so drop the script.

If srcdir != builddir, pass down MAKEOBJDIR to the FreeBSD make to

Also allow passing all the gmake options that FreeBSD make understands
to support useful flags like -k, -n, -q etc, and detect the number of

Allow users to configure notifications when TRIM operations are

the trim_finish event is generated for each vdev in the pool
which was trimmed, so the script will generate a notification

This commit adds two features to zed, that macOS desires. The first
is that when you unload the kernel module, zed would enter into a
cpubusy loop calling zfs_events_next() repeatedly. We now look for
ENODEV, returned by kernel, so zed can exit gracefully.
Second feature is -I (idle) (alas -P persist was taken) is for the
deamon to;
1; if started without ZFS kernel module, stick around waiting for it.
2; if kernel module is unloaded, go back to 1.
This is due to daemons in macOS is started by launchctl, and is
expected to stick around.
Currently, the busy loop only exists when errno is ENODEV. This is
to ensure that functionality that upstream expects is not changed.
It did not care about errors before, and it still does not. (with the
exception of ENODEV).
However, it is probably better that all errors
(ERESTART notwithstanding) exits the loop, and the issues complaining
about zed taking all CPU will go away.

These 6 tests consistently fail only on Fedora 31+, the failures
are related to the kernel rescanning the partition table on loopback
devices which is no longer reliable unless partprobe is used. In
order to enable the Fedora bot by default they are also being added
to the list until the tests can be updated. Any significant regression
in functionality covered by these tests will still be detected by the
FreeBSD builders.
