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".
By using INSTALL_LINK instead of calling ln during install the files
end up in the METALOG file as well if we use -DNO_ROOT and will be
included in a disk image when using makefs with METALOG as the input.
The other file that was not included in METALOG was /var/db/services.db
which is now also included for -DNO_ROOT.

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
message likely already belongs to the message payload.

To conform to RFC 5426, this function is intended to truncate messages
if they exceed the message size limits. Unfortunately, the amount of

The usermgmt API was stomping on a global ($user_gid to be specific)

pass into the API with the now-tainted variable contents.
Fixed by localizing menu-specific contents as to not leak outside API.

This command can be used by a sysadmin to either copy or migrate a data
file on one DS to another DS.
Its main use is to recover data files onto a mirrored DS after the DS has
been repaired and brought back online.
This command allows a sysadmin to display or modify the pnfsd.dsfile extended
attribute used by the pNFS MDS server in various ways.
Its main use is to set a DS's IP address to 0.0.0.0 when that DS has failed,
so that it will not be used for the file when brought back online after
being repaired.
kgdb now handles kernel module state internally, so the asf tool serves
no purpose.

This command can be used by a sysadmin to disable a malfunctioning pNFS server
mirrored DS. It is safe to use when a mirrored DS has already been disabled
via an I/O or network partitioning error.
The "-p" option specifies that the nfsd should run a pNFS service instead
of a regular NFS service. The "-m" option is only meaningful when used with
"-p" to specify that mirroring on the DSs should be done and on how many of
them.
This change requires the kernel changes committed as r334930.
The man page update will be committed as a separate commit soon.

also sort headers.
