Add an undocumented -r option preceding the bectl subcommand to specify a BE
root to operate out of. This will remain undocumented for now, as some
caveats apply:
- BEs cannot be activated in the pool that doesn't contain the rootfs
- bectl create cannot work out of the box without the -e option right now,
since it defaults to the rootfs and cross-pool cloning doesn't work like
that (IIRC)
Plumb the BE root through to libbe(3) so that some things -can- be done to
it, e.g.
bectl -r tank/ROOT create -e default upgrade
bectl -r tank/ROOT mount upgrade /mnt
this aides in some upgrade setups where rootfs is not necessarily ZFS, and
also makes it easier/possible to regression-test bectl when combined with a
file-backed zpool.

The extensions to the pf(4) ioctl interface have been made in a

will cause existing code that consumes that interface to use version 0
without source modifications. If version 0 consumers of the interface
are used against a new kernel that has had bandwidth parameters of

This approach does not work as-is for big endian architectures and was

Unfortunately, this changed the NVMe API and forces #ifdef's based on
the OS revision level in user space code.

it uses bytes instead of bit-fields inside the packed command structure.

The main dhclient process is Capsicumized but also chroots to
restrict filesystem access. With r322369, pidfile(3) maintains a
directory descriptor for the pidfile, which can cause the chroot
to fail in certain cases. To minimize the problem, only chroot
if we fail to enter capability mode, and store dhclient pidfiles
in a subdirectory of /var/run, thus restricting access via
pidfile(3)'s directory descriptor.

be_get_dataset_snapshots has been added to libbe(3), effectively returning
the same information as be_get_bootenv_props but for snapshots of the given
dataset. The assumption is that one will have the BE dataset name before
wanting to grab snapshots.
This also accomplishes the following:
- Proxy through zfs_nicenum as be_nicenum, because it looks better than
humanize_number and would presumably be useful to other libbe consumers.
- Rename be_get_snapshot_props to be_get_dataset_props, make it more useful

While it could be preferred to do this at insert in libbe(3), there's no
convenient way to insert at the head of an nvlist. Instead, we'll make two
passes over- once to print anything active either now or at nextboot, and
another to print everything else.
This doesn't actually impact performance in a significant way here, so we'll
worry about further optimizations if the need actually arises.
bectl list -a should show the boot environment, its relevant dataset, and
the snapshot it was created from. The header also changes to indicate the
rough order in which these things will show.
While here, start doing a little bit of spring cleaning and splitting
different bits out.
The timespecadd(3) family of macros were imported from NetBSD back in
r35029. However, they were initially guarded by #ifdef _KERNEL. In the
meantime, we have grown at least 28 syscalls that use timespecs in some
way, leading many programs both inside and outside of the base system to
redefine those macros. It's better just to make the definitions public.
Our kernel currently defines two-argument versions of timespecadd and
timespecsub. NetBSD, OpenBSD, and FreeDesktop.org's libbsd, however, define
three-argument versions. Solaris also defines a three-argument version, but
only in its kernel. This revision changes our definition to match the
common three-argument version.

Currently ifconfig(8) only prints the hex representation of ssid names
with non-ASCII characters. Many modern terminals are able to properly render
non-ASCII characters. This change checks if the terminal charmap is UTF-8,
and if so, will render the characters, rather than the hex value.
This behavior is circumvented by running ifconfig(8) in a non-UTF8 locale;
e.g. C or POSIX.
It was pointed out by kp@ during the review that APs have the option to
broadcast whether their SSIDs may be interpreted as UTF-8. Ideally, we would
honor this and only attempt this behavior if it's so-broadcasted by the AP.
However, a sample survey showed that hostapd will advertise this if
indicated in config but it doesn't seem to be so common in the AP market, so
this would be effectively useless as we'll rarely know if the SSID should be
renderable as UTF-8.
Despite this, it was decided to be OK with this anyways- there's a
straightforward path to doing it the right way based on advertisement by AP
if we need to go that route, and one can revert to old behavior easily
enough at runtime if we get it wrong.

While useful as an example, veriexecctl, as it is, has very little practical
use, since there is nothing ensuring the integrity of the manifest of hashes.
A more appropriate set of utilities will replace it.
Rather then combining hardlink creation for the geom(8) binary with
shared library build, move libraries to src/lib/geom so they are
built and installed normally. Create a common Makefile.classes

so the symlink and libraries stay in sync.
The relocation of libraries allows libraries to be build for 32-bit
compat. This also reduces the number of non-standard builds in
the system.
This commit is not sufficent to run a 32-bit /sbin/geom on a 64-bit

Normally pf rules are expected to do one of two things: pass the traffic or
block it. Blocking can be silent - "drop", or loud - "return", "return-rst",
"return-icmp". Yet there is a 3rd category of traffic passing through pf:
Packets matching a "pass" rule but when applying the rule fails. This happens
when redirection table is empty or when src node or state creation fails. Such
rules always fail silently without notifying the sender.
Allow users to configure this behaviour too, so that pf returns an error packet
in these cases.

The type of fingerprint supported depends on what MAC/veriexec fingerprint
modules have been loaded into the system. The veriexecctl application is

The following options are currently supported in MAC/veriexec and by the

can only be used as an interpreter in shell scripts.
file
Indicates that the fingerprint is associated with a file, not an
executable. Files have their fingerprints verified during open(2) and are
automatically made read only. This option may be used to verify shared
libraries have not been tampered with.
no_ptrace
If this option is set then the executable cannot be traced with the
ptrace(2) process tracing and debugging call.
trusted
If this option is set then the executable is allowed to write to the
mem(4) devices. By default, when verified execution is enforced, no
process is allowed to write to the mem(4) devices.

We shouldn't count the bytes set in c_addr for TS_CLRI and TS_BITS

follow, not now many c_addr spaces are used. Dump would dump core

the end to make a count.
