 1.18  07-Jul-2020  msaitoh No functional change:

- u_int32_t -> uint32_t
- KNF.
 1.17  13-Apr-2015  riastradh Convert sys/dev to use <sys/rndsource.h>.
 1.16  02-Feb-2012  tls branches: 1.16.6; 1.16.24;
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.
 1.15  19-Nov-2011  tls branches: 1.15.2;
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.
 1.14  19-Oct-2009  bouyer branches: 1.14.12;
Remove closes 3 & 4 from my licence. Lots of thanks to Soren Jacobsen
for the booring work !
 1.13  01-Jun-2008  tsutsui Split device_t/softc, with misc cosmetic changes.
 1.12  11-Dec-2005  christos branches: 1.12.70; 1.12.72; 1.12.74; 1.12.76;
merge ktrace-lwp.
 1.11  23-Jan-2005  dan attach tl(4) as an event source to rnd(4)
patches from Sean Davis in PR/28556
(slightly modified to actually catch our own interrupts)
 1.10  10-Nov-2003  wiz branches: 1.10.6; 1.10.8;
Spell address with two d's. Inspired by similar changes in OpenBSD,
originating from Jonathon Gray and forwarded by jmc@openbsd.
 1.9  02-Nov-2003  wiz deferred, not deffered. Inspired by Tom Cosgrove.
 1.8  30-Sep-2003  thorpej New generic I2C framework. Supports bit-bang and "intelligent" I2C
interface controllers (of varying intelligence levels).

Contributed by Wasabi Systems, Inc. Primarily written by Steve Woodford,
with some modification by me.
 1.7  20-Sep-2001  bouyer branches: 1.7.18;
- Allocate control structures at attach time rather than at init time.
Avoids using bus_dmamem_alloc/bus_dmamem_map at interrupt time.
Should fix PRs kern/13924 and kern/13979 from dive@endersgame.net
- while I'm there convert to use ether_ioctl.
 1.6  06-Aug-2001  bouyer branches: 1.6.2;
Improvement: allocate one page of dmamem for Rx, Tx and nullbuff instead of
3 different ones.
Also pass the rigth seg/nseg to bus_dmamem_free().
Correct types in debug printf's
 1.5  03-Aug-2001  bouyer - kill the carrier detect code. It's not usefull any more and can give
false informations on a loaded ethernet segement.
- convert to bus_dma(9) (better late than never :)
- add proper le32toh/htole32 so that it works on big-endian system (tested
on macppc).
Close PR kern/10327.
 1.4  23-Mar-2000  thorpej branches: 1.4.6; 1.4.8;
New callout mechanism with two major improvements over the old
timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
resource allocation.
- Insertion and removal of callouts is constant time, important as
this facility is used quite a lot in the kernel.

The old timeout()/untimeout() API has been removed from the kernel.
 1.3  11-Jan-1999  tron branches: 1.3.8;
Because memory mapped access doesn't fail only with the docking station
for the TI TravelMate 5000 but also with at least one Compaq NIC we
prefer I/O mapped access again. Fixes PR kern/6690.
 1.2  15-Aug-1998  bouyer branches: 1.2.4;
correct indent.
 1.1  11-Aug-1998  thorpej Adapt to the new MII code. This required splitting some structures into
if_tlvar.h, since the ThunderLAN PHY driver needs to know some things
about it's parent (and since it can only attach to a ThunderLAN chip,
this is the easiest way).
 1.2.4.1  11-Dec-1998  kenh The beginnings of interface detach support. Still some bugs, but mostly
works for me.

This work was originally by Bill Studenmund, and cleaned up by me.
 1.3.8.1  20-Nov-2000  bouyer Update thorpej_scsipi to -current as of a month ago
A i386 GENERIC kernel compiles without the siop, ahc and bha drivers
(will be updated later). i386 IDE/ATAPI and ncr work, as well as
sparc/esp_sbus. alpha should work as well (untested yet).
siop, ahc and bha will be updated once I've updated the branch to current
-current, as well as machine-dependant code.
 1.4.8.2  10-Jan-2002  thorpej Sync kqueue branch with -current.
 1.4.8.1  25-Aug-2001  thorpej Merge Aug 24 -current into the kqueue branch.
