bhyve: add basic basl implementation
Basl is the bhyve ASL compiler. At the moment, it's just a small wrapper
to call iasl, the Intel ASL compiler. As bhyve will gain support for
qemu's ACPI table loader in the future, it has to create ACPI tables on

This first implementation of basl supports creating an ACPI table by
appending raw bytes to it. It's also capable of loading all tables into

zfs tests: stop writing to arbitrary devices
TL;DR: Three ZFS tests created ZFS pools on all unmounted devices listed
in /etc/fstab, corrupting their contents. Stop that.
Imagine my surprise when the ESP on my main dev/test VM would "randomly"
become corrupted, making it unbootable. Three tests collect various devices
from the system and try to add them to a test pool. The test expects this
to fail because it _assumes_ these devices are in use and ZFS will correctly
reject the request.
My /etc/fstab has two entries for devices in /dev:
Note the `noauto` on the ESP. In a remarkable example of irony, I chose
this because it should keep the ESP more protected from corruption;
in fact, mounting it would have protected it from this case.
The tests added all of these devices to a test pool in a _single command_,
expecting the command to fail. The swap device was in use, so the command
correctly failed, but the ESP was added and therefore corrupted. However,
since the command correctly failed, the test didn't notice the ESP problem.
If each device had been added with its own command, the test _might_ have
noticed that one of them incorrectly succeeded. However, two of these
tests would not have noticed:
hotspare_create_001_neg was incorrectly specified as needing the Solaris
dumpadm command, so it was skipped. _Some_ of the test needs that command,
but it checks for its presence and runs fine without it.
Due to bug 241070, zpool_add_005_pos was marked as an expected failure.
Due to the coarse level of integration with ATF, this test would still
"pass" even if it failed for the wrong reason. I wrote bug 267554 to
reconsider the use of atf_expect_fail in these tests.
Let's further consider the use of various devices found around the system.
In addition to devices in /etc/fstab, the tests also used mounted devices
listed by the `mount` command. If ZFS behaves correctly, it will refuse
to added mounted devices and swap devices to a pool. However, these are
unit tests used by developers to ensure that ZFS still works after they
modify it, so it's reasonable to expect ZFS to do the _wrong_ thing
sometimes. Using random host devices is unsafe.
Fix the root problem by using only the disks provided via the "disks"
variable in kyua.conf. Use one to create a UFS file system and mount it.
Use another as a swap device. Use a third as a dump device, but expect
it to fail due to bug 241070.
While I'm here:
Due to commit 6b6e2954dd65, we can simply add a second dump device and
remove it in cleanup. We no longer need to save, replace, and restore the
pre-existing dump device.
The cleanup_devices function used `camcontrol inquiry` to distinguish disks
from other devices, such as partitions. That works fine for SCSI, but not
for ATA or VirtIO block. Use `geom disk list` instead.

Add support for managing UFS/FFS snapshots to fsck_ffs(8).
The kernel handles the managment of UFS/FFS snapshots. Since UFS/FFS
updates filesystem data (rather than always writing changes to new
locations like ZFS), the kernel must check every filesystem write
to see if the block being written is part of a snapshot. If it is
part of a snapshot, then the kernel must make a copy of the old
block value into a newly allocated block for the snapshot before
allowing the write to be done. Similarly, if a block is being freed,
the kernel must check to see if it is part of a snapshot and let
the snapshot claim the block rather than freeing it for future use.
When a snapshot is freed, its blocks need to be offered to older
snapshots and freed only if no older snapshots wish to claim them.
When snapshots were added to UFS/FFS they were integrated into soft
updates and just a small part of the management of snapshots needed
to be added to fsck_ffs(8) as soft updates minimized the set of
snapshot changes that might need correction. When journaling was
added to soft updates a much more complete knowledge of snapshots
needed to be added to fsck_ffs(8) for it to be able to properly
handle the filesystem changes that a journal rollback needs to do
(specifically the freeing and allocation of blocks). Since this
functionality was unavailable, the use of snapshots was disabled
when running with journaled soft updates.
This set of changes imports the kernel code for the management of
snapshots to fsck_ffs(8). With this code in place it will become
possible to enable snapshots when running with journalled soft
updates. The most immediate benefit will be the ability to use
snapshots to take consistent filesystem dumps on live filesystems.
Future work will be done to update fsck_ffs(8) to be able to use
snapshots to run in background on live filesystems running with
