6d1014a32b Add syslog(3) support to devd(8).
sbin/devd/devd.cc
        All output will now go to syslog(3) if devd is daemonized, or stderr
        if it's running in the foreground.

sbin/devd/devd.8
        Remove the "-D" flag.  Filtering messages by priority now
	happens in the usual syslog way.  For performance reasons, a few
	extra-verbose debugging statements are now conditional on the "-d" (do
	not daemonize) flag.

etc/syslog.conf
etc/newsyslog.conf
        Direct messages from devd(8) to /var/log/devd.log, but leave it
        disabled by default

8f8de1e127 - Modify swapon(8) so that it uses most of geli(8) defaults for swap,
which is presently: AES-XTS, no authentication.  Create provider
   with pagesize as sectorsize by default.
 - Rewrite parsing code for geli(8)-backed swap options, now options
   are required to be exact match, and unrecognized options will trigger
   a warning.
 - Don't initialize GELI device if it's already initialized.  This
   restores previous behavior.
 - Don't duplicate file descriptor when working with geli(8) and
   gbde(8) as there is no need to communicate with the utility other
   than exit status.
 - When calling swap_on_off_* routines, which_prog can only be SWAP_ON
   or SWAP_OFF.  Eliminate unneeded case branches by replacing switch
   with if's.
 - Plug a few memory leaks.

268a55bc98 - Add vnode-backed swap space specification support. This is enabled when
device names "md" or "md[0-9]*" and a "file" option are specified in
  /etc/fstab like this:

  md    none    swap    sw,file=/swap.bin       0       0

- Add GBDE/GELI encrypted swap space specification support, which
  rc.d/encswap supported.  The /etc/fstab lines are like the following:

  /dev/ada1p1.bde       none    swap    sw      0       0
  /dev/ada1p2.eli       none    swap    sw      0       0

  .eli devices accepts aalgo, ealgo, keylen, and sectorsize as options.

  swapctl(8) can understand an encrypted device in the command line
  like this:

  # swapctl -a /dev/ada2p1.bde

- "-L" flag is added to support "late" option to defer swapon until
  rc.d/mountlate runs.

- rc.d script change:

    rc.d/encswap -> removed
    rc.d/addswap -> just display a warning message if $swapfile is defined
    rc.d/swap1 -> renamed to rc.d/swap
    rc.d/swaplate -> newly added to support "late" option

These changes alleviate a race condition between device creation/removal
and swapon/swapoff.

49fac6101d Add firmware replacement and activation support to nvmecontrol(8) through
a new firmware command.

NVMe controllers may support up to 7 firmware slots for storing of
different firmware revisions.  This new firmware command supports
firmware replacement (i.e. firmware download) with or without immediate
activation, or activation of a previously stored firmware image.  It
also supports selection of the firmware slot during replacement
operations, using IDENTIFY information from the controller to
check that the specified slot is valid.

Newly activated firmware does not take effect until the new controller
reset, either via a reboot or separate 'nvmecontrol reset' command to the
same controller.

e1de133c2e Move the check whether the clear flag is set. This has 2 advantages
- When operating on a core file (-M) and -c is specified we don't clear
  the message buffer of the running system.
- If we don't have permission to clear the buffer print the error message
  only. That's what Linux does in this case, where this feature was ported
  from, and it ensures that the error message doesn't get lost in the noise.

3bd22a9cc8 Change the set and unset ctlreqs by making the index argument optional.
This allows setting attributes on tables. One simply does not provide
an index in that case. Otherwise the entry corresponding the index has
the attribute set or unset.

Use this change to fix a relatively longstanding bug in our GPT scheme
that's the result of rev 198097 (relatively harmless) followed by rev
237057 (damaging). The damaging part being that our GPT scheme always
has the active flag set on the PMBR slice. This is in violation with
EFI. Existing EFI implementions for both x86 and ia64 reject the GPT.
As such, GPT disks created by us aren't usable under EFI because of
that.

After this change, GPT disks never have the active flag set on the PMBR
slice. In order to make the GPT disk bootable under some x86 BIOSes,
the reason of rev 198097, one must now set the active attribute on the
gpt table. The kernel will apply this to the PMBR slice For (S)ATA:
	gpart set -a active ada0

To fix an existing GPT disk that has the active flag set in the PMBR,
and that does not need the flag, use (again for (S)ATA):
	gpart unset -a active ada0

The EBR, MBR & PC98 schemes, which also impement at least 1 attribute,
now check to make sure the entry passed is valid. They do not have
attributes that apply to the table.

Also document that newfs(8) options -n and -r are neither checked

a321935999 Convert over the etherswitch framework to use VLAN IDs per port, rather
than VLAN groups.

Some chips (eg this rtl8366rb) has a VLAN group per port - you first
define a set of VLANs in a vlan group, then you assign a VLAN group
to a port.

Other chips (eg the AR8xxx switch chips) have a VLAN ID array per
port - there's no group per se, just a list of vlans that can be
configured.

So for now, the switch API will use the latter and rely on drivers
doing the heavy lifting if one wishes to use the VLAN group method.
Maybe later on both can be supported.

7e659f9491 Add the Clang specific -Wmissing-variable-declarations to WARNS=6.
This compiler flag enforces that that people either mark variables
static or use an external declarations for the variable, similar to how
-Wmissing-prototypes works for functions.

Due to the fact that Yacc/Lex generate code that cannot trivially be
changed to not warn because of this (lots of yy* variables), add a
NO_WMISSING_VARIABLE_DECLARATIONS that can be used to turn off this
specific compiler warning.

b846efd7ec Add controller reset capability to nvme(4) and ability to explicitly
invoke it from nvmecontrol(8).

Controller reset will be performed in cases where I/O are repeatedly
timing out, the controller reports an unrecoverable condition, or
when explicitly requested via IOCTL or an nvme consumer.  Since the
controller may be in such a state where it cannot even process queue
deletion requests, we will perform a controller reset without trying
to clean up anything on the controller first.

Clang errors around printf could be trivially fixed, but the breakage in
sbin/fsdb were to significant for this type of change.

Submitter of this changeset has been notified and hopefully this can be
restored soon.

776816d32b Speed up fsck by caching the cylinder group maps in pass1 so
that they do not need to be read again in pass5. As this nearly
doubles the memory requirement for fsck, the cache is thrown away
if other memory needs in fsck would otherwise fail. Thus, the
memory footprint of fsck remains unchanged in memory constrained
environments.

This work was inspired by a paper presented at Usenix's FAST '13:
www.usenix.org/conference/fast13/ffsck-fast-file-system-checker

Details of this implementation appears in the April 2013 of ;login:
www.usenix.org/publications/login/april-2013-volume-38-number-2.
