The switch to lualoader creates a problem with userboot: the host is
inclined to build userboot with Lua, but the host userboot's interpreter
must match what's available on the guest. For almost all FreeBSD guests in
the wild, Lua is not yet available and a Lua-based userboot will fail.
This revision updates userboot protocol to version 5, which adds a
swap_interpreter callback to request a different interpreter, and tries to
determine the proper interpreter to be used based on how the guest
/boot/loader is compiled. This is still a bit of a guess, but it's likely
the best possible guess we can make in order to get it right. The
interpreter is now embedded in the resulting executable, so we can open
/boot/loader on the guest and hunt that down to derive the interpreter it
was built with.
Using -l with bhyveload will not allow an intepreter swap, even if the
loader specified happens to be a userboot with the wrong interpreter. We'll
simply complain about the mismatch and bail out.
For legacy guests without the interpreter marker, we assume they're 4th.
For new guests with the interpreter marker, we'll read it and swap over
to the proper interpreter if it doesn't match what the userboot we're using
was compiled with.
Both flavors of userboot are installed by default, userboot_4th.so and
userboot_lua.so. This fixes the build WITHOUT_FORTH as a coincidence, which
was broken by userboot being forced to 4th.

would simply wrap at the 2^32 boundary. The computations in the HFSC
scheduler and token bucket regulator have been modified to operate
correctly up to at least 100 Gbps. No other algorithms have been
examined or modified for correct operation above 2^32 bps (some may
have existing computation resolution or overflow issues at rates below
that threshold). pfctl(8) will now limit non-HFSC bandwidth
parameters to 2^32 - 1 before passing them to the kernel.
The extensions to the pf(4) ioctl interface have been made in a
backwards-compatible way by versioning affected data structures,
supporting all versions in the kernel, and implementing macros that
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
2^32 or greater configured by updated tools, such bandwidth parameters
will be reported as 2^32 - 1 bps by those old consumers.
All in-tree consumers of the pf(4) interface have been updated. To
update out-of-tree consumers to the latest version of the interface,
define PFIOC_USE_LATEST ahead of any includes and use the code of
pfctl(8) as a guide for the ioctls of interest.

PR#230752 shows a panic where an nfsd thread tries to do soconnect() on
the AF_LOCAL socket used by the nfsuserd while already holding an
exclusive lock on it. I am not 100% sure how this happens, but since an
AF_LOCAL socket is in the file system namespace it is conceivable that it
could lock it and then attempt an upcall to the nfsuserd.
However, reverting r320757 stops the nfsuserd from using an AF_LOCAL
socket, so it should avoid any such panic().
r320757 did fix a problem with running the nfsuserd when jails were
enabled, but that can be dealt with less elegantly by allowing the
use of an alternate address instead of 127.0.0.1.
The gssd daemon also uses an AF_LOCAL socket, but it will do upcalls
before the nfsd thread processes the RPC, so I think it should not
be suseptible to this problem.

The original NVMe API used bit-fields to represent fields in data
structures defined by the specification (e.g. the op-code in the command
data structure). The implementation targeted x86_64 processors and
defined the bit fields for little endian dwords (i.e. 32 bits).
This approach does not work as-is for big endian architectures and was
changed to use a combination of bit shifts and masks to support PowerPC.
Unfortunately, this changed the NVMe API and forces #ifdef's based on
the OS revision level in user space code.
This change reverts to something that looks like the original API, but
it uses bytes instead of bit-fields inside the packed command structure.
As a bonus, this works as-is for both big and little endian CPU
architectures.

Now for a non-root user it opens <path>/passwd, and populates the fields in
the returned struct passwd which aren't present in that file with well-known
canonical values, which duplicates the behavior of getpwnam(3). The net
effect is that the showuser output is identical whether using -R or not.

At the moment, hintmode and envmode are used to indicate whether static

static versions are mutually exclusive with loader(8)-provided environment.
hintmode *can* be reconfigured later to pull from the dynamic environment,
thus taking advantage of the loader(8) or post-kmem environment setting.
This changeset fixes both problems at once to move us from a semi-confusing
state to a consistent state: if an environment file, hints file, or
loader(8) environment are provided, we use them in a well-known order of
precedence:
- loader(8) environment
- static environment
- static hints file
Once the dynamic environment is setup this becomes a moot point. The
loader(8) and static environments are merged (respecting the above order of
precedence), and the static hints are merged in on an as-needed basis after
the dynamic environment has been setup.
Hints lookup are changed to respect all of the above. Before the dynamic
environment is setup, lookups use the above-mentioned order and fallback to
the next environment if a matching hint is not found. Once the dynamic
environment is setup, that is used on its own since it captures all of the
above information plus any dynamic kenv settings that came up later in boot.
The following tangentially related changes were made to res_find:
- A hintp cookie is now passed in so that related searches continue using
the chain of environments (or dynamic environment) without relying on
global state
- All three environments will be searched if they actually have valid hints
to use, rather than just choosing the first environment that actually had
a hint and rolling with that only

loader(8) and static environments are merged (respecting the above order of
precedence), and the static hints are merged in on an as-needed basis after
the dynamic environment has been setup.
Hints lookup are changed to respect all of the above. Before the dynamic
environment is setup, lookups use the above-mentioned order and fallback to
the next environment if a matching hint is not found. Once the dynamic
environment is setup, that is used on its own since it captures all of the
above information plus any dynamic kenv settings that came up later in boot.
The following tangentially related changes were made to res_find:
- A hintp cookie is now passed in so that related searches continue using
the chain of environments (or dynamic environment) without relying on
global state
- All three environments will be searched if they actually have valid hints
to use, rather than just choosing the first environment that actually had
a hint and rolling with that only
The hintmode sysctl has been ripped out. static_{env,hints}.disabled are
still honored and will disable their respective environments from being used
for hint lookups and from being merged into the dynamic environment, as
expected.

For developers gensnmptree can now generate functions for enums to convert
between enums and strings and to check the validity of a value.
The sources in FreeBSD are now in sync with the upstream which allows to
bring in IPv6 modifications.
r335871 added support for an optional suffix of "#mds_path" that can be
applied to each entry in the "-p" option argument. This specifies that
the DS should be used to store files for the file system on the MDS
at "mds_path".
This patch documents this optional suffix.
This is a content change.
Without this patch, the pNFS server distributes the data storage files across
all of the specified DSs.
A tester noted that it would be nice if a system administrator could control
which DSs are used to store the file data for a given exported MDS file system.
This patch adds an optional suffix for each entry in the "-p" option argument
that specifies "store file data for this MDS file system" in this DS.
The patch should only affect sites using the pNFS server (specified via the
"-p" command line option for nfsd.
The interface between the nfsd and the kernel has changed with this patch,
so anyone using the "-p" option needs to rebuild their nfsd from sources
with this patch applied to them.
Discussed with: james.rose@framestore.com
The refactoring of the syslogd code to format messages using iovecs
slightly altered the output of syslogd by placing the facility/priority
after the hostname, as opposed to printing it right before. This change
reverts the behaviour to be consistent with how it was before.

When pnfsdscopymr(8) is used to create a mirror of a file on a mirrored
pNFS service, it expects to find an entry in the extended attribute for
IP address 0.0.0.0.
This patch adds a "-m" option which can be used to create these entrie(s).
It also tightens up the checks for use of incompatible command line options.
The kernel code assumes that nfsdargs.addr == NULL and nfsdargs.addrlen == 0
when there is no "-p" argument used for starting the nfsd.
This small patch ensures this is the case. In practice, I believe this always
happened, since "nfsdargs" was the last element on the stack for "main()",
but this little patch ensures it will be the case.
Spotted by inspection while adding a new optional field for "-p".

As previously noted, kernel's processing of these means that the first
appearance of a hint/variable wins. Flipping the order of concatenation
means that later variables override earlier variables, as expected when one
does:
hints x
hints y
Where perhaps x is:
hint.aw_sid.0.disable=1
and y is:
hint.aw_sid.0.disable=0
The expectation would be that a later appearing variable would override an
earlier appearing variable, such as with `device`/`nodevice`, device.hints,
and other similarly structured data files.
Previously, only one 'env' file could be specified. Later 'env' directives
would overwrite earlier 'env' directives. This is inconsistent with every
other file-accepting directives which process files in order, including
hints.
A caveat applies to both hints and env that isn't mentioned: they're
concatenated in the order of appearance, so they're not actually applied in
the way one might think by supplying:
hints x
hints y
Hints in x will take precedence over same-name hints in y due to how
the kernel processes them, stopping at the first line that matches the hint
we're searching for. Future work will flip the order of concatenation so
that later files may still properly override earlier files.
In practice, this likely doesn't matter at all due to the nature of the
beast.
envvar allows adding individual environment variables to the kernel's static
environment without the overhead of pulling in a full file. envvar in a
config looks like:
envvar some_var=5
All envvar-provided variables will be added after the env file is processed,
so envvar keys that exist in the previous env will be overwritten by
whatever value is set here in the kernel configuration directly.
As an aside, envvar lines are intentionally tokenized differently from
basically every other line. We used a named state when ENVVAR is encountered
to gobble up the rest of the line, which will later be cleaned and validated
in post-processing by sanitize_envline. This turns out to be the simplest
and cleanest way to allow the flexibility that kenv does while not
compromising on silly hacks.

The changes made in r326573 required that messages always start with an
RFC 3164 timestamp. It looks like certain devices, but also certain
logging libraries (Python 3's "logging" package) simply don't generate
RFC 3164 formatted messages containing a timestamp.
Make timestamps optional again. When the timestamp is missing, also
assume that the message contains no hostname. The first word of the

given interval, which is counted in seconds since exit of the previous
invocation of the job. Example user crontab entry:
@25 sleep 10
The example will launch 'sleep 10' every 35 seconds. This is a rather
useless example above, but clearly explains the functionality.
The practical goal here is to avoid overlap of previous job invocation
to a new one, or to avoid too short interval(s) for jobs that last long
and doesn't have any point of immediate launch soon after previous run.
Another useful effect of interval jobs can be noticed when a cluster of
machines periodically communicates with a single node. Running the task
time based creates too much load on the node. Running interval based
spreads invocations across machines in cluster. Note that -j/-J won't

This will manage pmc functionality with a more
manageable structure of subcommands rather than the
gradually accreted spaghetti logic of overlapping flags
that exists in pmcstat.
This is intended to ultimately have all the same functionality
as pmcannotate+pmccontrol+pmcstat. Currently it just has
"stat" and "system-stat" - counters for the process itself and counters
for the system as a whole respectively (i.e. system-stat includes kernel
threads). Note that the rusage results (page faults/context switches/
user/sys) for stat-system will not account for the system as a whole -
only for the child process specified on the command line.
Implementing stat was suggested by mjg@ and the output is based on that
from Linux's "perf stat".
