needed for CPU vulnerability mitigations and a lot more

Just remove the `OBJECT_FILES_NON_STANDARD` definitions. A follow-up

Currently, the zfs initramfs-tools boot script under local-top calls
`vgchange -ay`, which unconditionally activates all logical volumes
(LVs) in all discovered volume groups (VGs). This causes all LVs to be
active after boot. However, users may prefer to not activate certain
VGs/LVs on boot. They might normally use the `--setautoactivation n`
VG/LV flag or the `auto_activation_volume_list` LVM config option to
achieve this, but since the script unconditionally activates all LVs,
neither has an effect.
To fix this, call `vgchange -aay` instead. This triggers LVM
autoactivation, which honors autoactivation settings such as the
`--setautoactivation` flag. It is also more in line with the LVM
documentation, which says autoactivation is "meant to be used by
activation commands that are run automatically by the system" [1].
Note that this change might break misconfigured setups that have ZFS
on top of an LV for which autoactivation is disabled.

Build RPMs - Build release RPMs and tarballs and put them into an

the ZIP file mirrors the ZFS yum repo.
Test repo - Test install the ZFS RPMs from the ZFS repo. On
Almalinux, this will do a DKMS and KMOD test install
from both the regular and testing repos. On Fedora,
it will do a DKMS install from the regular repo. All

d634d20d1b had been intended to fix a
potential information leak issue where the compiler's optimization
passes appeared to remove `memset()` operations that sanitize sensitive
data before memory is freed for use by the rest of the kernel.
When I wrote it, I had assumed that the compiler would not remove the
other `memset()` operations, but upon reflection, I have realized that
this was a bad assumption to make. I would rather have a very slight
amount of additional overhead when calling `gcm_clear_ctx()` than risk a
future compiler remove `memset()` calls. This is likely to happen if
someone decides to try doing link time optimization and the person will
not think to audit the assembly output for issues like this, so it is
best to preempt the possibility before it happens.

Bisecting identified the redacted send/receive as the source of the bug
for issue #12014. Specifically the call to
dsl_dataset_hold_obj(&fromds) has been replaced by
dsl_dataset_hold_obj_flags() which passes a DECRYPT flag and creates
a key mapping. A subsequent dsl_dataset_rele_flag(&fromds) is missing
and the key mapping is not cleared. This may be inadvertedly used, which
results in arc_untransform failing with ECKSUM in:
arc_untransform+0x96/0xb0 [zfs]
dbuf_read_verify_dnode_crypt+0x196/0x350 [zfs]

Fix this by restoring the call to dsl_dataset_hold_obj().
The same applies for to_ds: here replace dsl_dataset_rele(&to_ds) with
dsl_dataset_rele_flags().
Both leaked key mappings will cause a panic when exporting the
sending pool or unloading the zfs module after a non-raw send from

I've found that QEMU/KVM guest memory accounted as shared also
included into NR_FILE_PAGES. But it is actually a non-evictable

parameter makes ARC to ignore shrinker requests while page cache
does not really have anything to evict, ending up in OOM killer
killing the QEMU process.
Instead use of NR_ACTIVE_FILE + NR_INACTIVE_FILE should represent
the part of a page cache that is actually evictable, which should
be safer to use as a reference for ARC scaling.

It turns out that approach taken in the original version of the patch

actually does it - when sb is being torn down, access to it
is serialized via sb->s_umount rwsem, only when that lock is taken
is it okay to work with s_flags - and the other mistake I was doing
was trying to make SB_ACTIVE work, but apparently the kernel checks
the negative variant - not SB_DYING and not SB_BORN.
Kernels pre-6.6 don't have SB_DYING, but check if sb is hashed

since 4.10, bio->bi_opf needs to be checked to determine all kinds of
flush requests. this was the case prior to the commit referenced below,
but the order of ifdefs was not the usual one (newest up top), which
might have caused this to slip through.
this fixes a regression when using zvols as Qemu block devices, but
might have broken other use cases as well. the symptoms are that all
sync writes from within a VM configured to use such a virtual block
devices are ignored and treated as async writes by the host ZFS layer.
this can be verified using fio in sync mode inside the VM, for example
with
fio \
--filename=/dev/sda --ioengine=libaio --loops=1 --size=10G \
--time_based --runtime=60 --group_reporting --stonewall --name=cc1 \
--description="CC1" --rw=write --bs=4k --direct=1 --iodepth=1 \
--numjobs=1 --sync=1
which shows an IOPS number way above what the physical device underneath
supports, with "zpool iostat -r 1" on the hypervisor side showing no
sync IO occuring during the benchmark.
with the regression fixed, both fio inside the VM and the IO stats on
the host show the expected numbers.

Before 4.20, kernel_siginfo_t was just called siginfo_t. This was
causing the kthread_dequeue_signal_3arg_task check, which uses
kernel_siginfo_t, to fail on older kernels.
In d6b8c17f1, we started checking for the "new" three-arg
dequeue_signal() by testing for the "old" version. Because that test is
explicitly using kernel_siginfo_t, it would fail, leading to the build
trying to use the new three-arg version, which would then not comile.
This commit fixes that by avoiding checking for the old 3-arg
dequeue_signal entirely. Instead, we check for the new one, as well as
the 4-arg form, and we use the old form as a fallback. This way, we
never have to test for it explicitly, and once we're building
HAVE_SIGINFO will make sure we get the right kernel_siginfo_t for it, so
everything works out nice.

directories, as the new get_name code is much more efficient than the
default zfs_readdir. This is actually part of
20232ecfaa in 2.3. But I've taken only
the minimum code to implement get_name, and not the rest of the long
name changes.

When replacing a disk, a child process is forked to run a script called
zfs_prepare_disk (which can be useful for disk firmware update or health
check). The parent than calls waitpid and checks the child error/status
code.
However, the _reap_children thread (created from zed_exec_process to
manage zedlets) also waits for all children with the same PGID and can
stole the signal, causing the replace operation to be aborted.
As waitpid returns -1, the parent incorrectly assume that the child
process had an error or was killed. This, in turn, leaves the newly
added disk in REMOVED or UNAVAIL status rather than completing the
replace process.
This patch changes the PGID of the child process execuing the
prepare script, shielding it from the _reap_children thread.
