riastradh | MD rnd.h cleanups. Please let me know if I broke anything!

tls | branches: 1.14.6; 1.14.24; 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.

tls | branches: 1.13.2; 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.

tsutsui | branches: 1.12.4; KNF and misc cosmetics.
|
1.11 |
| 25-Jan-2011 |
tsutsui | Split device_t/softc. Tested on Indy.

| 11-Dec-2005 |
christos | branches: 1.9.100; 1.9.106; 1.9.108; merge ktrace-lwp.
|
1.8 |
| 30-Dec-2004 |
rumble | Prepend HPC3 macros universally with "HPC3_" to distinctly recognise the corresponding revision and maintain consistency with HPC1.
No functional change intended.
|
1.7 |
| 29-Dec-2004 |
rumble | HPC1 seems to benefit from larger rings. This should be especially true on the transmit side, which appears to be significantly slower at interrupting than HPC3.
XXX I used to be able to occasionally wedge the chip with SQ_NTXDESC == 32, but have not yet been able to reproduce that behaviour this evening with a larger value.
|
1.6 |
| 29-Dec-2004 |
rumble | Remove the static sq_trace array and make it per-device as multiple seeq interfaces may exist. While here, add a few trace actions, move the related macros into sqvar.h, and enhance the sq_trace_dump output a bit.
|
1.5 |
| 30-Dec-2003 |
sekiya | branches: 1.5.2; 1.5.6; Adapt if_sq to HPC abstraction layer. It took both Steve Rumble and myself to untangle the unhappiness that arises from the design differences between HPC1 and HPC3.
|
1.4 |
| 02-May-2002 |
rafal | branches: 1.4.10; Add interrupt counter for Seeq interrupts; also, make sure to reset back to "recieve only my frames & broadcasts" and clear the ALLMULTI flag if we have no multicast addresses in our list.
|
1.3 |
| 13-Mar-2002 |
simonb | Replace lots of 8x<space> with <tabs> and other miscellaneous indentation fixes. Wrap a couple of long lines. Use <return-type>\n<function name> as per KNF in a few places.
|
1.2 |
| 07-Jun-2001 |
thorpej | branches: 1.2.2; 1.2.8; - Differentiate beteen the 8003 and 80c03 (the 80c03 has some additional features). - Implement crude multicast support -- enable reception of all multicast frames if we have any addresses on the multicast list. TODO: use the 64-bit hash table on the 80c03. - Implement promiscuous mode.
IPv6 doesn't quite work yet -- DAD finds a duplicate for the link-local. The 8003 hears its own transmissions, but IFF_SIMPLEX is not set, so I'm a little confused.

thorpej | Support for the Seeq 8003 Ethernet attached to the HPC ASIC, found on Indigo2 and Indy.
From Rafal K. Boni.
