We have three sets of DTYPE_ constants in the kernel:
	altq		Drop 		Type
	disklabel	Disk 		Type
	file		Descriptor	Type
(not to mention constants that contain the string DTYPE).
Let's make them two, by changing the disklabel one to be DisK TYPE since the
other disklabel constants seem to do that. Not many userland programs use
these constants (and the ones that they do are mostly in ifdefs). They will
be fixed shortly.

make more drivers use disk_ioctl, and add a dev parameter to it so that
we can merge the "easy" disklabel ioctls to it. Ultimately all this will
go do dk_ioctl once all the drivers have been converted.

Centralize wedge ioctls in disk_ioctl.

Rebase to HEAD as of a few days ago.

Merge tls-earlyentropy branch into HEAD.

Rebase.

Add d_discard to all struct cdevsw instances I could find.

All have been set to "nodiscard"; some should get a real implementation.

Add d_discard to all struct bdevsw instances I could find.

I've set them all to nodiscard. Some of them (wd, dk, vnd, ld,
raidframe, maybe cgd) should be implemented for real.

Be a little more clear and consistent about harvesting entropy from devices:

1) deprecate RND_FLAG_NO_ESTIMATE

2) define RND_FLAG_COLLECT_TIME, RND_FLAG_COLLECT_VALUE

3) define RND_FLAG_ESTIMATE_TIME, RND_FLAG_ESTIMATE_VALUE

4) define RND_FLAG_DEFAULT: RND_FLAG_COLLECT_TIME|
   RND_FLAG_COLLECT_VALUE|RND_FLAG_ESTIMATE_TIME

5) Make entropy harvesting from environmental sensors a little more generic
   and remove it from individual sensor drivers.

6) Remove individual open-coded delta-estimators for values from a few
   places in the tree (uvm, environmental drivers).

7) 0 -> RND_FLAG_DEFAULT, actually gather entropy from various drivers
   that had stubbed out code, other minor cleanups.

Change (mostly mechanically) every cdevsw/bdevsw I can find to use
designated initializers.

I have not built every extant kernel so I have probably broken at
least one build; however I've also found and fixed some wrong
cdevsw/bdevsw entries so even if so I think we come out ahead.

Entropy-pool implementation move and cleanup.

1) Move core entropy-pool code and source/sink/sample management code
   to sys/kern from sys/dev.

2) Remove use of NRND as test for presence of entropy-pool code throughout
   source tree.

3) Remove use of RND_ENABLED in device drivers as microoptimization to
   avoid expensive operations on disabled entropy sources; make the
   rnd_add calls do this directly so all callers benefit.

4) Fix bug in recent rnd_add_data()/rnd_add_uint32() changes that might
   have lead to slight entropy overestimation for some sources.

5) Add new source types for environmental sensors, power sensors, VM
   system events, and skew between clocks, with a sample implementation
   for each.

ok releng to go in before the branch due to the difficulty of later
pullup (widespread #ifdef removal and moved files).  Tested with release
builds on amd64 and evbarm and live testing on amd64.

First step of random number subsystem rework described in
<20111022023242.BA26F14A158@mail.netbsd.org>.  This change includes
the following:

	An initial cleanup and minor reorganization of the entropy pool
	code in sys/dev/rnd.c and sys/dev/rndpool.c.  Several bugs are
	fixed.  Some effort is made to accumulate entropy more quickly at
	boot time.

	A generic interface, "rndsink", is added, for stream generators to
	request that they be re-keyed with good quality entropy from the pool
	as soon as it is available.

	The arc4random()/arc4randbytes() implementation in libkern is
	adjusted to use the rndsink interface for rekeying, which helps
	address the problem of low-quality keys at boot time.

	An implementation of the FIPS 140-2 statistical tests for random
	number generator quality is provided (libkern/rngtest.c).  This
	is based on Greg Rose's implementation from Qualcomm.

	A new random stream generator, nist_ctr_drbg, is provided.  It is
	based on an implementation of the NIST SP800-90 CTR_DRBG by
	Henric Jungheim.  This generator users AES in a modified counter
	mode to generate a backtracking-resistant random stream.

	An abstraction layer, "cprng", is provided for in-kernel consumers
	of randomness.  The arc4random/arc4randbytes API is deprecated for
	in-kernel use.  It is replaced by "cprng_strong".  The current
	cprng_fast implementation wraps the existing arc4random
	implementation.  The current cprng_strong implementation wraps the
	new CTR_DRBG implementation.  Both interfaces are rekeyed from
	the entropy pool automatically at intervals justifiable from best
	current cryptographic practice.

	In some quick tests, cprng_fast() is about the same speed as
	the old arc4randbytes(), and cprng_strong() is about 20% faster
	than rnd_extract_data().  Performance is expected to improve.

	The AES code in src/crypto/rijndael is no longer an optional
	kernel component, as it is required by cprng_strong, which is
	not an optional kernel component.

	The entropy pool output is subjected to the rngtest tests at
	startup time; if it fails, the system will reboot.  There is
	approximately a 3/10000 chance of a false positive from these
	tests.  Entropy pool _input_ from hardware random numbers is
	subjected to the rngtest tests at attach time, as well as the
	FIPS continuous-output test, to detect bad or stuck hardware
	RNGs; if any are detected, they are detached, but the system
	continues to run.

	A problem with rndctl(8) is fixed -- datastructures with
	pointers in arrays are no longer passed to userspace (this
	was not a security problem, but rather a major issue for
	compat32).  A new kernel will require a new rndctl.

	The sysctl kern.arandom() and kern.urandom() nodes are hooked
	up to the new generators, but the /dev/*random pseudodevices
	are not, yet.

	Manual pages for the new kernel interfaces are forthcoming.

Catchup with rmind-uvmplock merge.

Add support for the Extensible MIPS ("eMIPS") platform.  The
NetBSD/emips port runs on Xilinx and Beecube FPGA systems and the
Giano system simulator.

eMIPS is a platform developed at Microsoft Research for researching
reconfigurable computing.  eMIPS allows dynamic loading and scheduling
of application-specific circuits for the purpose of accelerating
computations based on the current workload.

NetBSD eMIPS support for NetBSD 4.x was written at Microsoft Research
by Alessandro Forin and Neil Pittman.  Microsoft Corporation has
donated full copyright to The NetBSD Foundation.

Platform support for eMIPS is the first part of Microsoft's
contribution.  The second part includes the hardware accelerator
framework and will be proposed on tech-kern soon.
