FreeBSD's dhclient-script already has a special case for when the router

it's a different address that doesn't fall in the interface's subnet.

The fsck_ffs(8) utility has two subsystems for reading and writing
inodes. The getnextinode() interface is used in Pass 1 (and Pass
1b if needed) to sequentially walk through all the inodes in the
filesystem. The ginode() interface is used to read and write
individual inodes. Pass 1 uses a mix of both interfaces. This
change ensures that ginode() returns a pointer to the inode in the

requested inode so that all modifications to the inode are made in
a single place and are all written to the disk together.

The UFS filesystem expects to find '.' and '..' as the first two entries
in a directory. The kernel's UFS name cache can become quite confused
when these two entries are not present as the first two entries.
Prior to this change, when the fsck_ffs(8) utility detected that
'.' and/or '..' were missing, it would report them, but only offered
to replace them if the space at the beginning of the directory was
available. Otherwise it was left to the system administrator to
move the offending file(s) out of the way and then rerun fsck_ffs(8)
to create the '.' and '..' entries.
With this change, fsck_ffs(8) will always be able to create the '.'

directory block. If there is no room in the directory block to which
to move them, they are placed in the lost+found directory.

into ffs_sbsearch() to allow use by other parts of the system.
Historically only fsck_ffs(8), the UFS filesystem checker, had code
to track down and use alternate UFS superblocks. Since fsdb(8) used
much of the fsck_ffs(8) implementation it had some ability to track
down alternate superblocks.
This change extracts the code to track down alternate superblocks
from fsck_ffs(8) and puts it into a new function ffs_sbsearch() in
sys/ufs/ffs/ffs_subr.c. Like ffs_sbget() and ffs_sbput() also found
in ffs_subr.c, these functions can be used directly by the kernel
subsystems. Additionally they are exported to the UFS library,
libufs(8) so that they can be used by user-level programs. The new
functions added to libufs(8) are sbfind(3) that is an alternative
to sbread(3) and sbsearch(3) that is an alternative to sbget(3).
See their manual pages for further details.
The utilities that have been changed to search for superblocks are
dumpfs(8), fsdb(8), ffsinfo(8), and fsck_ffs(8). Also, the prtblknos(8)
tool found in tools/diag/prtblknos searches for superblocks.
The UFS specific mount code uses the superblock search interface
when mounting the root filesystem and when the administrator doing
a mount(8) command specifies the force flag (-f). The standalone UFS
boot code (found in stand/libsa/ufs.c) uses the superblock search
code in the hope of being able to get the system up and running so
that fsck_ffs(8) can be used to get the filesystem cleaned up.
The following utilities have not been changed to search for
superblocks: clri(8), tunefs(8), snapinfo(8), fstyp(8), quot(8),
dump(8), fsirand(8), growfs(8), quotacheck(8), gjournal(8), and
glabel(8). When these utilities fail, they do report the cause of
the failure. The one exception is the tasting code used to try and
figure what a given disk contains. The tasting code will remain
silent so as not to put out a slew of messages as it trying to taste
every new mass storage device that shows up.

The fsck_ffs(8) utility made sanity checks of critical superblock
fields by comparing the values of those fields in the standard
superblock againt the values of those fields in the last alternate
superblock. The code for validating a superblock now cover all the
checked fields as well as many more. Further the checks done are
far more comprehensive. So we now drop the alternate superblock
checks as they no longer provide value. Dropping these checks also
eliminates the need to read the alternate superblock.
Rather than trying to shoehorn flags into the requested superblock
address, create a separate flags parameter to the ffs_sbget()
function in sys/ufs/ffs/ffs_subr.c. The ffs_sbget() function is
used both in the kernel and in user-level utilities through export
to the sbget() function in the libufs(3) library (see sbget(3)
for details). The kernel uses ffs_sbget() when mounting UFS
filesystems, in the glabel(8) and gjournal(8) GEOM utilities,
and in the standalone library used when booting the system
from a UFS root filesystem.
The ffs_sbget() function reads the superblock located at the byte
offset specified by its sblockloc parameter. The value UFS_STDSB
may be specified for sblockloc to request that the standard
location for the superblock be read.
The two existing options are now flags:
UFS_NOHASHFAIL will note if the check hash is wrong but will still
return the superblock. This is used by the bootstrap code to
give the system a chance to come up so that fsck can be run to
correct the problem.
UFS_NOMSG indicates that superblock inconsistency error messages
should not be printed. It is used by programs like fsck that
want to print their own error message and programs like glabel(8)
that just want to know if a UFS filesystem exists on a partition.
One additional flag is added:
UFS_NOCSUM causes only the superblock itself to be returned, but does
not read in any auxiliary data structures like the cylinder group
summary information. It is used by clients like glabel(8) that
just want to check for possible filesystem types. Using UFS_NOCSUM
skips the superblock checks for csum data which allows superblocks
that have corrupted csum data to be read and used.
The validate_sblock() function checks that the superblock has not
been corrupted in a way that can crash or hang the system. Unless
the UFS_NOMSG flag is specified, it will print out any errors that
it finds. Prior to this commit, validate_sblock() returned as soon
as it found an inconsistency so would print at most one message.
It now does all its checks so when UFS_NOMSG has not been specified
will print out everything that it finds inconsistent.

The reported problem is that some geli commands exit with a
success status when they should exit with a failed status.
The gctl_error() function is defined differently in the kernel
(in sys/geom/geom_ctl.c) versus in the geom user facilities (in
sbin/geom/misc/subr.c). In the kernel, calling gctl_error() causes
an error return to be set while in the user version it does not.
It was only by a quirk that had been added to the user geom return

to set the error return showed up.
This patch adds the missing setting of the error code when calling

Since there is no warning that -c will be ignored when the -q option

The setvlantag() and setvlanproto() functions are used in two scenarios:
when we create a new vlan interface and when we update an existing
interface.
These are distinguished by the getvlan() at the end of the functions. If
this fails we assume that is because the interface doesn't exist (so
we're creating a new one). We only update the 'params' struct, and
expect the settings to be applied when we vlan_create().
However, if we're updating an existing interface we do not retrieve the
current settings, and can end up invalidating settings.
Fix this by using the settings we retrieved while checking which
scenario we're in.
Note that we do not address this for setvlandev(), because if_vlan does
not allow the vlan parent device to be changed without disassociating it
first (with ifconfig vlanX -vlandev).

Generally, access to the kernel debugger is considered to be unsafe from
a security perspective since it presents an unrestricted interface to
inspect or modify the system state, including sensitive data such as
signing keys.
However, having some access to debugger functionality on production
systems may be useful in determining the cause of a panic or hang.
Therefore, it is desirable to have an optional policy which allows
limited use of ddb(4) while disabling the functionality which could
reveal system secrets.
This loadable MAC module allows for the use of some ddb(4) commands
while preventing the execution of others. The commands have been broadly
grouped into three categories:
- Those which are 'safe' and will not emit sensitive data (e.g. trace).
Generally, these commands are deterministic and don't accept
arguments.
- Those which are definitively unsafe (e.g. examine <addr>, search
<addr> <value>)
- Commands which may be safe to execute depending on the arguments
provided (e.g. show thread <addr>).
Safe commands have been flagged as such with the DB_CMD_MEMSAFE flag.
Commands requiring extra validation can provide a function to do so.
For example, 'show thread <addr>' can be used as long as addr can be
checked against the system's list of process structures.
The policy also prevents debugger backends other than ddb(4) from
executing, for example gdb(4).

Historically, GEOM utilities (gpart(8), gstripe(8), gmirror(8),

gctl_error() they would exit with EXIT_FAILURE, otherwise they would
return with EXIT_SUCCESS. If they used gctl_error() to output an
informational message, for example when run with the -v (verbose)
option, they would mistakenly exit with EXIT_FAILURE. A further
limitation of the gctl_error() function was that it could only be
called once. Messages from any additional calls to gctl_error()
would be silently discarded.
To resolve these problems a new function, gctl_msg() has been added.
It can be called multiple times to output multiple messages. It
also has an additional errno argument which should be zero if it is
an informational message or an errno value (EINVAL, EBUSY, etc) if
it is an error. When done the gctl_post_messages() function should
be called to indicate that all messages have been posted. If any
of the messages had a non-zero errno, the utility will EXIT_FAILURE.
If only informational messages (with zero errno) were posted, the
