Rewrite entropy subsystem.
Primary goals:
1. Use cryptography primitives designed and vetted by cryptographers.
2. Be honest about entropy estimation.
3. Propagate full entropy as soon as possible.
4. Simplify the APIs.
5. Reduce overhead of rnd_add_data and cprng_strong.
6. Reduce side channels of HWRNG data and human input sources.
7. Improve visibility of operation with sysctl and event counters.
Caveat: rngtest is no longer used generically for RND_TYPE_RNG
rndsources. Hardware RNG devices should have hardware-specific
health tests. For example, checking for two repeated 256-bit outputs
works to detect AMD's 2019 RDRAND bug. Not all hardware RNGs are
necessarily designed to produce exactly uniform output.
ENTROPY POOL
- A Keccak sponge, with test vectors, replaces the old LFSR/SHA-1
kludge as the cryptographic primitive.
- `Entropy depletion' is available for testing purposes with a sysctl
knob kern.entropy.depletion; otherwise it is disabled, and once the
system reaches full entropy it is assumed to stay there as far as
modern cryptography is concerned.
- No `entropy estimation' based on sample values. Such `entropy
estimation' is a contradiction in terms, dishonest to users, and a
potential source of side channels. It is the responsibility of the
driver author to study the entropy of the process that generates
the samples.
- Per-CPU gathering pools avoid contention on a global queue.
- Entropy is occasionally consolidated into global pool -- as soon as
it's ready, if we've never reached full entropy, and with a rate
limit afterward. Operators can force consolidation now by running
sysctl -w kern.entropy.consolidate=1.
- rndsink(9) API has been replaced by an epoch counter which changes
whenever entropy is consolidated into the global pool.
. Usage: Cache entropy_epoch() when you seed. If entropy_epoch()
has changed when you're about to use whatever you seeded, reseed.
. Epoch is never zero, so initialize cache to 0 if you want to reseed
on first use.
. Epoch is -1 iff we have never reached full entropy -- in other
words, the old rnd_initial_entropy is (entropy_epoch() != -1) --
but it is better if you check for changes rather than for -1, so
that if the system estimated its own entropy incorrectly, entropy
consolidation has the opportunity to prevent future compromise.
- Sysctls and event counters provide operator visibility into what's
happening:
. kern.entropy.needed - bits of entropy short of full entropy
. kern.entropy.pending - bits known to be pending in per-CPU pools,
can be consolidated with sysctl -w kern.entropy.consolidate=1
. kern.entropy.epoch - number of times consolidation has happened,
never 0, and -1 iff we have never reached full entropy
CPRNG_STRONG
- A cprng_strong instance is now a collection of per-CPU NIST
Hash_DRBGs. There are only two in the system: user_cprng for
/dev/urandom and sysctl kern.?random, and kern_cprng for kernel
users which may need to operate in interrupt context up to IPL_VM.
(Calling cprng_strong in interrupt context does not strike me as a
particularly good idea, so I added an event counter to see whether
anything actually does.)
- Event counters provide operator visibility into when reseeding
happens.

- Unwired for now; will be rewired in a subsequent commit.

thorpej | - Eliminate the global "boottime" variable, which was being accessed
without any synchronization against changes by e.g. clock_settime().
- Replace with new getbinboottime() / getnanoboottime() / getmicroboottime()
functions (naming mirrors that of other time access functions in kern_tc.c).
It returns the (maybe-converted) value of timebasebin, which also tracks
our estimate of when the system was booted (i.e. the legacy "boottime" was
redundant).
XXX There needs to be a lockless synchronization mechanism for reading
timebasebin, but this is a problem in kern_tc.c that pre-existed these
"boottime" changes. At least now the problem is centralized in one location.

a 48 CPU machine w/DIAGNOSTIC.

errno values through p_emuldata. Notably, we cannot alter the syscall
method like most ports do with syscall_intern, since they do it via
p_mdproc, so MI code is not possible there.

pooka | Add initial work on a rump virtual cpu scheduler. This is necessary
for kernel code which has been written to avoid MP contention by
using cpu-local storage (most prominently, select and pool_cache).
Instead of always assuming rump_cpu, the scheduler must now be run
(and unrun) on all entry points into rump. Likewise, rumpuser
unruns and re-runs the scheduler around each potentially blocking
operation. As an optimization, I modified some locking primitives
to try to get the lock without blocking before releasing the cpu.
Also, ltsleep was modified to assume that it is never called without
the biglock held and made to use the biglock as the sleep interlock.
Otherwise there is just too much drama with deadlocks. If some
kernel code wants to call ltsleep without the biglock, then, *snif*,
it's no longer supported and rump and should be modified to support
newstyle locks anyway.

pooka | Add proof-of-concept code for enabling system calls to rump virtual
kernels running in other processes on the same machine or on an
entirely different host. I wrote this a while ago and am now
committing it mainly to avoid losing it. It works, but could do
with a little tuning here and there.
What this will hopefully eventually buy us is the ability to use
standard userland tools to configure rump kernels, e.g. ifconfig(8)
and route(8) could be used to configure the networking stack provided
by a rump kernel. Also some distributed OS implications may apply.
fun fact: a system call which just does copyin/copyout takes >1000x
longer when made over the LAN as compared to when made on the same
machine.

Make the clock interrupt tick based on absolute time instead of

breakdown of commit:
* install relevant headers into /usr/include/rump
* build sys/rump/librump/rumpuser and sys/rump/librump/rumpkern
from src/lib and install as librumpuser and librump, respectively
+ this retains the ability to test a librump build with just the
kernel sources at hand
* move sys/rump/fs/lib/libukfs and sys/rump/fs/lib/libp2k to src/lib
for general consumption, they are not kernel-space dwellers anyway
* build and install sys/rump/fs/lib/lib$fs as librumpfs_$fs
* add chapter 3 manual pages for rump, rumpuser, ukfs and p2k
* build and install userspace kernel file system daemons if MKPUFFS=yes
is spexified
* retire fsconsole for now, it will make a comeback with an actually
implemented version shortly

with the regular mount_psshfs command line as an argument:
golem> ./syspuffs /usr/sbin/mount_psshfs ftp.netbsd.org:/pub /puffs
This will make the mount appear as usual, with the exception that the
requests will be passed through puffs both in the kernel and userspace:
ftp.netbsd.org:/pub on /puffs type puffs|p2k|puffs|psshfs

Hide NetBSD kernel headers completely from ukfs. This includes creating
accessors for:

* struct uio
* struct vnode
* struct vattr
and some namespace games for:
* namei flags
* VOPs
* enum vtype
Also, split rump services into two categories: library private and public
(rump_private.h and rump.h, respectively).
As a result, it is now possible to compile and use the NetBSD kernel
file systems on Linux (and probably other systems too with very
little work), although the makefiles need a bit of work to make it
a pleasureable experience.

Implement debugging feature for pserialize(9)
The debugging feature detects violations of pserialize constraints.
It causes a panic:
- if a context switch happens in a read section, or
- if a sleepable function is called in a read section.
The feature is enabled only if LOCKDEBUG is on.
Discussed on tech-kern@

state "VS_ACTIVE" to assert a loaded vnode with usecount > 0.
- Redo FSTRANS in vnode_if.c and use it for VOP_LOCK and VOP_UNLOCK.
- Cleanup the genfs lock operations.
- Make "struct vnode_impl" member "vi_lock" a krwlock_t again.
- Remove the lock type argument from fstrans_start and
fstrans_start_nowait,
remove now unused FSTRANS state "FSTRANS_SUSPENDING".

(all via patch)
Get &rsc->sc_dksc only when we know 'rsc' is not NULL. This was actually
harmless because we didn't use the pointer then.
Gcc -Os on landisk is not smart enough to follow the conditional
initialization and warns, unconditionaly initialize dksc at declaration
with a XXX gcc comment.
Improve wording in comments in raid_dumpblock().
in many device attach paths, allocate memory with M_WAITOK instead of M_NOWAIT
and remove code to handle failures that can no longer happen.
Nix trailing whitespace.
if raidframe sets booted_device, log a debug message about it.
merge two debug lines in auto-root selection.
convert non-config-handled "DEBUG_ROOT" to aprint_debug().
now it's possible to get boot-time info about raidframe root
device selection with simple "boot -x".
Align the behavior of different boot methods in RAIDframe
We enforce the documented and paritally implemented behavior when
looking for the kernel in RAID 1 sets without a partition name given.
We search for:
- A GPT partition with bootme attribute set
- A FFS or LFS patititon
- The first partition
Fix root search in RAID 1 sets
We use the wedge information given by bootstrap, where the kernel was
found. This requires src/sys/arch/i386/stand/i386/lib/biosdisk.c 1.59
to work in all cases.
