b7eb47e290 Add a new flag '-k' to ifconfig(8), indicating that it is alright to
print potentially sensitive keying material to stdout.  With the new
802.11 support, ifconfig(8) is now capable of printing 802.11 keys,
and did by default for the root user, which is undesirable in some
environments.  Now it will not print keying material unless requested
(and available to the user).

1b3a4f4e7b Check the vendor and device, not subvendor and subdevice, when looking for
channel devices.  This should fix Dell 2450/2550/2650 systems that have RAID
enabled.  This will likely not fix 2400 systems though as I don't have the
appropriate PCI Id info for them.

0cddce4989 Add libmemstat(3), a library for use by debugging and monitoring
applications in tracking kernel memory statistics.  It provides an
abstracted interface to uma(9) and malloc(9) statistics, wrapped
around the recently added binary stream sysctls for the allocators.

Using this interface, it is easy to build monitoring tools, query
specific memory types for usage information, etc.  Facilities are
provided for binding caller-provided data to memory types,
incremental updates of memory types, and queries that span multiple
allocators.

Support for additional allocators is (relatively) easy to add.

The API for libmemstat(3) will probably change some over time as
consumers are written, and requirements evolve.  It is written to
avoid encoding ABIs for data structure layout into consuming
applications for this reason.

7a52a97eb3 Introduce a new sysctl, vm.zone_stats, which exports UMA(9) allocator
statistics via a binary structure stream:

- Add structure 'uma_stream_header', which defines a stream version,
  definition of MAXCPUs used in the stream, and the number of zone
  records in the stream.

- Add structure 'uma_type_header', which defines the name, alignment,
  size, resource allocation limits, current pages allocated, preferred
  bucket size, and central zone + keg statistics.

- Add structure 'uma_percpu_stat', which, for each per-CPU cache,
  includes the number of allocations and frees, as well as the number
  of free items in the cache.

- When the sysctl is queried, return a stream header, followed by a
  series of type descriptions, each consisting of a type header
  followed by a series of MAXCPUs uma_percpu_stat structures holding
  per-CPU allocation information.  Typical values of MAXCPU will be
  1 (UP compiled kernel) and 16 (SMP compiled kernel).

This query mechanism allows user space monitoring tools to extract
memory allocation statistics in a machine-readable form, and to do so
at a per-CPU granularity, allowing monitoring of allocation patterns
across CPUs in order to better understand the distribution of work and
memory flow over multiple CPUs.

While here, also export the number of UMA zones as a sysctl
vm.uma_count, in order to assist in sizing user swpace buffers to
receive the stream.

A follow-up commit of libmemstat(3), a library to monitor kernel memory
allocation, will occur in the next few days.  This change directly
supports converting netstat(1)'s "-mb" mode to using UMA-sourced stats
rather than separately maintained mbuf allocator statistics.

2c743d361a In an earlier world order, UMA would flush per-CPU statistics to the
zone whenever it was moving buckets between the zone and the cache,
or when coalescing statistics across the CPU.  Remove flushing of
statistics to the zone when coalescing statistics as part of sysctl,
as we won't be running on the right CPU to write to the cache
statistics.

Add a missed gathering of statistics: when uma_zalloc_internal()
does a special case allocation of a single item, make sure to update
the zone statistics to represent this.  Previously this case wasn't
accounted for in user-visible statistics.

cd814b2692 Introduce a new sysctl, kern.malloc_stats, which exports kernel malloc
statistics via a binary structure stream:

- Add structure 'malloc_type_stream_header', which defines a stream
  version, definition of MAXCPUS used in the stream, and a number of
  malloc_type records in the stream.

- Add structure 'malloc_type_header', which defines the name of the
  malloc type being reported on.

- When the sysctl is queried, return a stream header, followed by a
  series of type descriptions, each consisting of a type header
  followed by a series of MAXCPUS malloc_type_stats structures holding
  per-CPU allocation information.  Typical values of MAXCPUS will be 1
  (UP compiled kernel) and 16 (SMP compiled kernel).

This query mechanism allows user space monitoring tools to extract
memory allocation statistics in a machine-readable form, and to do so
at a per-CPU granularity, allowing monitoring of allocation patterns
across CPUs in order to better understand the distribution of work and
memory flow over multiple CPUs.

While here:

- Bump statistics width to uint64_t, and hard code using fixed-width
  type in order to be more sure about structure layout in the stream.
  We allocate and free a lot of memory.

- Add kmemcount, a counter of the number of registered malloc types,
  in order to avoid excessive manual counting of types.  Export via a
  new sysctl to allow user-space code to better size buffers.

- De-XXX comment on no longer maintaining the high watermark in old
  sysctl monitoring code.

A follow-up commit of libmemstat(3), a library to monitor kernel memory
allocation, will occur in the next few days.  Likewise, similar changes
to UMA.

d26dd2d99e When devfs cloning takes place, provide access to the credential of the
process that caused the clone event to take place for the device driver
creating the device.  This allows cloned device drivers to adapt the
device node based on security aspects of the process, such as the uid,
gid, and MAC label.

- Add a cred reference to struct cdev, so that when a device node is
  instantiated as a vnode, the cloning credential can be exposed to
  MAC.

- Add make_dev_cred(), a version of make_dev() that additionally
  accepts the credential to stick in the struct cdev.  Implement it and
  make_dev() in terms of a back-end make_dev_credv().

- Add a new event handler, dev_clone_cred, which can be registered to
  receive the credential instead of dev_clone, if desired.

- Modify the MAC entry point mac_create_devfs_device() to accept an
  optional credential pointer (may be NULL), so that MAC policies can
  inspect and act on the label or other elements of the credential
  when initializing the skeleton device protections.

- Modify tty_pty.c to register clone_dev_cred and invoke make_dev_cred(),
  so that the pty clone credential is exposed to the MAC Framework.

While currently primarily focussed on MAC policies, this change is also
a prerequisite for changes to allow ptys to be instantiated with the UID
of the process looking up the pty.  This requires further changes to the
pty driver -- in particular, to immediately recycle pty nodes on last
close so that the credential-related state can be recreated on next
lookup.

o Add two new ioctl's KBADDKBD and KBRELKBD. These are used to add and remove
  keyboard to (and from) kbdmux(4) keyboard multiplexer;

o Introduce new kbd_find_keyboard2() function. It does exactly the same job
  as kbd_find_keyboard() function except it allows to specify starting index.
  This function can be used to iterate over keyboards array;

o Re-implement kbd_find_keyboard() as call to kbd_find_keyboard2() with starting
  index of zero;

o Make sure syscons(4) passed KBADDKBD and KBRELKBD ioctl's onto currently
  active keyboard.

- Make sure timer0_max_count is set to a correct value in the lapic case.
- Revert i8254_restore() to explicitly reprogram timer 0 rather than

  the counter if the max count changes which it never does on resume.  This
