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.

Add a driver for the RDC Semiconductor RDC R6040 10/100 Ethernet controller, as found in the vortex86 SoCs (http://www.vortex86dx.com). Ported from freebsd. Not added to amd64's GENERIC because this CPU is 32bit only. thanks to DM&P Electronics, Inc for providing documentation and sample devices for this work.
