9102 zfs should be able to initialize storage devices
The first access to a disk block can incur a performance penalty on some
platforms (e.g. AWS's EBS, VMware VMDKs). Therefore it is recommended that
volumes be "thick provisioned", where supported by the platform (VMware).
Thick provisioning is time consuming and often is ignored. If the thick
provision step is omitted, customers will see suboptimal performance until
we have written to all parts of the LUN. ZFS should be able to initialize
any unused storage to remove any first-write penalty that exists.

Code analysis and runtime analysis using truss(8) indicate that the only
privileged operations performed by ntpd are adjusting system time, and
(re-)binding to privileged UDP port 123. These changes add a new mac(4)
policy module, mac_ntpd(4), which grants just those privileges to any
process running with uid 123.
This also adds a new user and group, ntpd:ntpd, (uid:gid 123:123), and makes
them the owner of the /var/db/ntp directory, so that it can be used as a
location where the non-privileged daemon can write files such as the
driftfile, and any optional logfile or stats files.
Because there are so many ways to configure ntpd, the question of how to
configure it to run without root privs can be a bit complex, so that will be
addressed in a separate commit. These changes are just what's required to
grant the limited subset of privs to ntpd, and the small change to ntpd to
prevent it from exiting with an error if running as non-root.

boot_parse_args to parse all the args in a vector
boot_howto_to_env Convert howto bits to env vars
boot_env_to_howto Return howto mask mased on what's set in the environment.
All these routines return an int that's the bitmask of the args
translated to RB_* flags. As a special case, the 'S' flag sets the
comconsole_speed env var. Any arg that looks like a=b will set the env
key 'a' to value 'b'. If =b is omitted, 'a' is set to '1'. This
should help us reduce the number of redundant copies of these routines
in the tree. It should also give a more uniform experience between
platforms.
Also, invent a new flag RB_PROBE that's set when 'P' is parsed. On
x86 + BIOS, this means 'probe for the keyboard, and if it's not there
set both RB_MULTIPLE and RB_SERIAL (which means show the output on
both video and serial consoles, but make serial primary). Others it
may be some similar concept of probing, but it's loader dependent
what, exactly, it means.
These routines are suitable for /boot/loader and/or the kernel,
though they may not be suitable for the tightly hand-rolled-for-space

The code is organized into a few distinct pieces:
* The meta-data store (in veriexec_metadata.c) which maps a file system
identifier, file identifier, and generation key tuple to veriexec
meta-data record.
* Fingerprint management (in veriexec_fingerprint.c) which deals with
calculating the cryptographic hash for a file and verifying it. It also
manages the loadable fingerprint modules.
* MAC policy implementation (in mac_veriexec.c) which implements the
following MAC methods:
mpo_init
Initializes the veriexec state, meta-data store, fingerprint modules,
and registers mount and unmount EVENTHANDLERs
mpo_syscall
Implements the following per-policy system calls:
MAC_VERIEXEC_CHECK_FD_SYSCALL
Check a file descriptor to see if the referenced file has a valid
fingerprint.
MAC_VERIEXEC_CHECK_PATH_SYSCALL
Check a path to see if the referenced file has a valid fingerprint.
mpo_kld_check_load
Check if loading a kld is allowed. This checks if the referenced vnode
has a valid fingerprint.
mpo_mount_destroy_label
Clears the veriexec slot data in a mount point label.
mpo_mount_init_label
Initializes the veriexec slot data in a mount point label.
The file system identifier is saved in the veriexec slot data.
mpo_priv_check
Check if a process is allowed to write to /dev/kmem and /dev/mem
devices.
If a process is flagged as trusted, it is allowed to write.
mpo_proc_check_debug
Check if a process is allowed to be debugged. If a process is not
flagged with VERIEXEC_NOTRACE, then debugging is allowed.
mpo_vnode_check_exec
Check is an exectuable is allowed to run. If veriexec is not enforcing
or the executable has a valid fingerprint, then it is allowed to run.
NOTE: veriexec will complain about mismatched fingerprints if it is
active, regardless of the state of the enforcement.
mpo_vnode_check_open
Check is a file is allowed to be opened. If verification was not
requested, veriexec is not enforcing, or the file has a valid
fingerprint, then veriexec will allow the file to be opened.
mpo_vnode_copy_label
Copies the veriexec slot data from one label to another.
mpo_vnode_destroy_label
Clears the veriexec slot data in a vnode label.
mpo_vnode_init_label
Initializes the veriexec slot data in a vnode label.
The fingerprint status for the file is stored in the veriexec slot data.
* Some sysctls, under security.mac.veriexec, for setting debug level,
fetching the current state in a human-readable form, and dumping the
fingerprint database are implemented.
* The MAC policy implementation source file also contains some utility
functions.
* A set of fingerprint modules for the following cryptographic hash
algorithms:
RIPEMD-160, SHA1, SHA2-256, SHA2-384, SHA2-512
* Loadable module builds for MAC/veriexec and fingerprint modules.
WARNING: Using veriexec with NFS (or other network-based) file systems is

- Large refactoring of the control API towards an extensible solution;
the goal is to allow the addition of more commands and extension of

The idea of Storage Pool Checkpoint (aka zpool checkpoint) deals with
exactly that. It can be thought of as a “pool-wide snapshot” (or a
variation of extreme rewind that doesn’t corrupt your data). It remembers
the entire state of the pool at the point that it was taken and the user
can revert back to it later or discard it. Its generic use case is an
administrator that is about to perform a set of destructive actions to ZFS
as part of a critical procedure. She takes a checkpoint of the pool before
performing the actions, then rewinds back to it if one of them fails or puts
the pool into an unexpected state. Otherwise, she discards it. With the
assumption that no one else is making modifications to ZFS, she basically
wraps all these actions into a “high-level transaction”.

Since the FW can be shared between PCI functions it is common that

The solution is to use a FW locking mechanism using semaphore space to
provide a way to synchronize between functions. The FW semaphore is
acquired via config cycle access. First the VSEC gateway must be
acquired, then the semaphore can be locked by writing a value to it
and confirmed it's locked by reading the same value back. The process
in the same to free the semaphore, except the value written should be

The TCP Blackbox Recorder allows you to capture events on a TCP connection
in a ring buffer. It stores metadata with the event. It optionally stores
the TCP header associated with an event (if the event is associated with a
packet) and also optionally stores information on the sockets.
It supports setting a log ID on a TCP connection and using this to correlate
multiple connections that share a common log ID.
You can log connections in different modes. If you are doing a coordinated
test with a particular connection, you may tell the system to put it in
mode 4 (continuous dump). Or, if you just want to monitor for errors, you
can put it in mode 1 (ring buffer) and dump all the ring buffers associated
with the connection ID when we receive an error signal for that connection
ID. You can set a default mode that will be applied to a particular ratio

The upstream repository is on github BLAKE2/libb2. Files landed in
sys/contrib/libb2 are the unmodified upstream files, except for one
difference: secure_zero_memory's contents have been replaced with
explicit_bzero() only because the previous implementation broke powerpc
link. Preferential use of explicit_bzero() is in progress upstream, so
it is anticipated we will be able to drop this diff in the future.
sys/crypto/blake2 contains the source files needed to port libb2 to our
build system, a wrapped (limited) variant of the algorithm to match the API
of our auth_transform softcrypto abstraction, incorporation into the Open
Crypto Framework (OCF) cryptosoft(4) driver, as well as an x86 SSE/AVX
accelerated OCF driver, blake2(4).
Optimized variants of blake2 are compiled for a number of x86 machines
(anything from SSE2 to AVX + XOP). On those machines, FPU context will need
to be explicitly saved before using blake2(4)-provided algorithms directly.
Use via cryptodev / OCF saves FPU state automatically, and use via the
auth_transform softcrypto abstraction does not use FPU.
The intent of the OCF driver is mostly to enable testing in userspace via
/dev/crypto. ATF tests are added with published KAT test vectors to
validate correctness.

The general idea here is to provide userspace programs with well-defined
sources of entropy, in a fashion that doesn't require opening a new file
descriptor (ulimits) or accessing paths (/dev/urandom may be restricted
by chroot or capsicum).
getrandom(2) is the more general API, and comes from the Linux world.
Since our urandom and random devices are identical, the GRND_RANDOM flag
is ignored.
getentropy(3) is added as a compatibility shim for the OpenBSD API.
truss(1) support is included.
Tests for both system calls are provided. Coverage is believed to be at
least as comprehensive as LTP getrandom(2) test coverage. Additionally,
instructions for running the LTP tests directly against FreeBSD are provided
in the "Test Plan" section of the Differential revision linked below. (They

I'm not making any judgement on which implementation is better. If I pulled

ConnectX-4/5 devices in mlx5core.
The dump is obtained by reading a predefined register map from the
non-destructive crspace, accessible by the vendor-specific PCIe
capability (VSC). The dump is stored in preallocated kernel memory and
managed by the mlx5tool(8), which communicates with the driver using a
character device node.
The utility allows to store the dump in format
<address> <value>
into a file, to reset the dump content, and to manually initiate the
dump.
A call to mlx5_fwdump() should be added at the places where a dump
must be fetched automatically. The most likely place is right before a

9079 race condition in starting and ending condesing thread for indirect vdevs
illumos/illumos-gate@667ec66f1b
The timeline of the race condition is the following:
[1] Thread A is about to finish condesing the first vdev in spa_condense_indirect_thread(),
so it calls the spa_condense_indirect_complete_sync() sync task which sets the
spa_condensing_indirect field to NULL. Waiting for the sync task to finish, thread A
sleeps until the txg is done. When this happens, thread A will acquire spa_async_lock
and set spa_condense_thread to NULL.
[2] While thread A waits for the txg to finish, thread B which is running spa_sync() checks
whether it should condense the second vdev in vdev_indirect_should_condense() by checking
the spa_condensing_indirect field which was set to NULL by spa_condense_indirect_thread()
from thread A. So it goes on and tries to spawn a new condensing thread in
spa_condense_indirect_start_sync() and the aforementioned assertions fails because thread A
has not set spa_condense_thread to NULL (which is basically the last thing it does before
returning).
The main issue here is that we rely on both spa_condensing_indirect and spa_condense_thread to
signify whether a condensing thread is running. Ideally we would only use one throughout the
codebase. In addition, for managing spa_condense_thread we currently use spa_async_lock which
basically tights condensing to scrubing when it comes to pausing and resuming those actions
during spa export.

illumos/illumos-gate@5cabbc6b49https://www.illumos.org/issues/7614:
This project allows top-level vdevs to be removed from the storage pool with
“zpool remove”, reducing the total amount of storage in the pool. This
operation copies all allocated regions of the device to be removed onto other
devices, recording the mapping from old to new location. After the removal is
complete, read and free operations to the removed (now “indirect”) vdev must
be remapped and performed at the new location on disk. The indirect mapping
table is kept in memory whenever the pool is loaded, so there is minimal
performance overhead when doing operations on the indirect vdev.
The size of the in-memory mapping table will be reduced when its entries
become “obsolete” because they are no longer used by any block pointers in
the pool. An entry becomes obsolete when all the blocks that use it are
freed. An entry can also become obsolete when all the snapshots that
reference it are deleted, and the block pointers that reference it have been
“remapped” in all filesystems/zvols (and clones). Whenever an indirect block
is written, all the block pointers in it will be “remapped” to their new
(concrete) locations if possible. This process can be accelerated by using
the “zfs remap” command to proactively rewrite all indirect blocks that
reference indirect (removed) vdevs.
Note that when a device is removed, we do not verify the checksum of the data
that is copied. This makes the process much faster, but if it were used on
redundant vdevs (i.e. mirror or raidz vdevs), it would be possible to copy
the wrong data, when we have the correct data on e.g. the other side of the
mirror. Therefore, mirror and raidz devices can not be removed.

support for other compression algorithms (zstd) in this role without

used to select an algorithm.
Also change the (non-default) GZIO kernel option to not enable

Currently, bwn(4) relies on the siba_bwn(4) bus driver to provide support
for the on-chip SSB interconnect found in Broadcom's older PCI(e) Wi-Fi
adapters. Non-PCI Wi-Fi adapters, as well as the newer BCMA interconnect
found in post-2009 Broadcom Wi-Fi hardware, are not supported by
siba_bwn(4).
The bhnd(4) bus driver (also used by the FreeBSD/MIPS Broadcom port)
provides a unified kernel interface to a superset of the hardware supported
by siba_bwn; by attaching bwn(4) via bhnd(4), we can support both modern
PCI(e) Wi-Fi devices based on the BCMA backplane interconnect, as well as
Broadcom MIPS WiSoCs that include a D11 MAC core directly attached to their
SSB or BCMA backplane.
This diff introduces opt-in bwn(4) support for bhnd(4) by providing:
- A small bwn(4) driver subclass, if_bwn_bhnd, that attaches via
bhnd(4) instead of siba_bwn(4).
- A bhndb(4)-based PCI host bridge driver, if_bwn_pci, that optionally
probes at a higher priority than the siba_bwn(4) PCI driver.
- A set of compatibility shims that perform translation of bwn(4)'s
siba_bwn function calls into their bhnd(9) API equivalents when bwn(4)
is attached via a bhnd(4) bus parent. When bwn(4) is attached via
siba_bwn(4), all siba_bwn function calls are simply passed through to
their original implementations.
To test bwn(4) with bhnd(4), place the following lines in loader.conf(5):
hw.bwn_pci.preferred="1"
if_bwn_pci_load="YES
bwn_v4_ucode_load="YES"
bwn_v4_lp_ucode_load="YES"
To verify that bwn(4) is using bhnd(4), you can check dmesg:
bwn0: <Broadcom 802.11 MAC/PHY/Radio, rev 15> ... on bhnd0
... or devinfo(8):

bwn(4)/bhnd(4) has been tested for regressions with most chipsets currently

- BCM4318
- BCM4321

- Querying clock frequency and latency.
Additionally, rather than updating legacy PWRCTL support to conform to the

- Since PWRCTL is only found in older SSB-based chipsets, translation from

7431 ZFS Channel Programs
illumos/illumos-gate@dfc115332cdfc115332chttps://www.illumos.org/issues/7431
ZFS channel programs (ZCP) adds support for performing compound ZFS
administrative actions via Lua scripts in a sandboxed environment (with time
and memory limits).
This initial commit includes both base support for running ZCP scripts, and a
small initial library of API calls which support getting properties and
listing, destroying, and promoting datasets.
Testing: in addition to the included unit tests, channel programs have been in
use at Delphix for several months for batch destroying filesystems. The
dsl_destroy_snaps_nvl() call has also been replaced with

8552 ZFS LUA code uses floating point math
illumos/illumos-gate@916c8d8811916c8d8811https://www.illumos.org/issues/8552
In the LUA interpreter used by "zfs program", the lua format() function
accidentally includes support for '%f' and friends, which can cause compilation
problems when building on platforms that don't support floating-point math in
the kernel (e.g. sparc). Support for '%f' friends (%f %e %E %g %G) should be
removed, since there's no way to supply a floating-point value anyway (all
numbers in ZFS LUA are int64_t's).

FreeBSD notes:
- zfs-program.8 manual page is taken almost as is from the vendor repository,
no FreeBSD-ification done
- fixed multiple instances of NULL being used where an integer is expected
- replaced ETIME and ECHRNG with ETIMEDOUT and EDOM respectively
This commit adds a modified version of Lua 5.2.4 under
sys/cddl/contrib/opensolaris/uts/common/fs/zfs/lua, mirroring the
upstream. See README.zfs in that directory for the description of Lua
customizations.
See zfs-program.8 on how to use the new feature.
