844d9543dc Add ccp(4): experimental driver for AMD Crypto Co-Processor
* Registers TRNG source for random(4)
* Finds available queues, LSBs; allocates static objects
* Allocates a shared MSI-X for all queues.  The hardware does not have
  separate interrupts per queue.  Working interrupt mode driver.
* Computes SHA hashes, HMAC.  Passes cryptotest.py, cryptocheck tests.
* Does AES-CBC, CTR mode, and XTS.  cryptotest.py and cryptocheck pass.
* Support for "authenc" (AES + HMAC).  (SHA1 seems to result in
  "unaligned" cleartext inputs from cryptocheck -- which the engine
  cannot handle.  SHA2 seems to work fine.)
* GCM passes for block-multiple AAD, input lengths

Largely based on ccr(4), part of cxgbe(4).

Rough performance averages on AMD Ryzen 1950X (4kB buffer):
aesni:      SHA1: ~8300 Mb/s    SHA256: ~8000 Mb/s
ccp:               ~630 Mb/s    SHA256:  ~660 Mb/s  SHA512:  ~700 Mb/s
cryptosoft:       ~1800 Mb/s    SHA256: ~1800 Mb/s  SHA512: ~2700 Mb/s

As you can see, performance is poor in comparison to aesni(4) and even
cryptosoft (due to high setup cost).  At a larger buffer size (128kB),
throughput is a little better (but still worse than aesni(4)):

aesni:      SHA1:~10400 Mb/s    SHA256: ~9950 Mb/s
ccp:              ~2200 Mb/s    SHA256: ~2600 Mb/s  SHA512: ~3800 Mb/s
cryptosoft:       ~1750 Mb/s    SHA256: ~1800 Mb/s  SHA512: ~2700 Mb/s

AES performance has a similar story:

aesni:      4kB: ~11250 Mb/s    128kB: ~11250 Mb/s
ccp:               ~350 Mb/s    128kB:  ~4600 Mb/s
cryptosoft:       ~1750 Mb/s    128kB:  ~1700 Mb/s

This driver is EXPERIMENTAL.  You should verify cryptographic results on
typical and corner case inputs from your application against a known- good
implementation.

fe182ba1d0 aesni(4): Add support for x86 SHA intrinsics
Some x86 class CPUs have accelerated intrinsics for SHA1 and SHA256.
Provide this functionality on CPUs that support it.

This implements CRYPTO_SHA1, CRYPTO_SHA1_HMAC, and CRYPTO_SHA2_256_HMAC.

Correctness: The cryptotest.py suite in tests/sys/opencrypto has been
enhanced to verify SHA1 and SHA256 HMAC using standard NIST test vectors.
The test passes on this driver.  Additionally, jhb's cryptocheck tool has
been used to compare various random inputs against OpenSSL.  This test also
passes.

Rough performance averages on AMD Ryzen 1950X (4kB buffer):
aesni:      SHA1: ~8300 Mb/s    SHA256: ~8000 Mb/s
cryptosoft:       ~1800 Mb/s    SHA256: ~1800 Mb/s

So ~4.4-4.6x speedup depending on algorithm choice.  This is consistent with
the results the Linux folks saw for 4kB buffers.

The driver borrows SHA update code from sys/crypto sha1 and sha256.  The
intrinsic step function comes from Intel under a 3-clause BSDL.[0]  The
intel_sha_extensions_sha<foo>_intrinsic.c files were renamed and lightly
modified (added const, resolved a warning or two; included the sha_sse
header to declare the functions).

a317fb03c2 crypto(9): Use a more specific error code when a capable driver is not found
When crypto_newsession() is given a request for an unsupported capability,
raise a more specific error than EINVAL.

This allows cryptotest.py to skip some HMAC tests that a driver does not
support.

d86680b073 Convert some idioms over to py3k-compatible idioms
- Import print_function from __future__ and use print(..) instead of `print ..`.
- Use repr instead of backticks when the object needs to be dumped, unless
  print(..) can do it lazily. Use str instead of backticks as appropriate
  for simplification reasons.

This doesn't fully convert these modules over py3k. It just gets over some of
the trivial compatibility hurdles.

005fdbbc69 cryptotest.py: Actually use NIST-KAT HMAC test vectors and test the right hashes
Previously, this test was entirely a no-op as no vector in the NIST-KAT file
has a precisely 20-byte key.

Additionally, not every vector in the file is SHA1.  The length field
determines the hash under test, and is now decoded correctly.

Finally, due to a limitation I didn't feel like fixing in cryptodev.py, MACs
are truncated to 16 bytes in this test.

With this change and the uncommitted D12437 (to allow key sizes other than
those used in IPSec), the SHA tests in cryptotest.py actually test something
and e.g. at least cryptosoft passes the test.

b3eaa68045 cryptotest.py: Do not run AES-CBC or AES-GCM tests on non-AES crypto(4) drivers
For some reason, we only skipped AES-XTS tests if a driver was not in the
aesmodules list.  Skip other AES modes as well to prevent spurious failures
in non-AES drivers.

7abea82d17 cryptotest.py: Add a seatbelt that we're actually testing anything
Without nist-kat installed, cryptotest.py is a no-op.  Showing 'success' in
that case is unhelpful.

a0fc6fa93f tests/sys/opencrypto/runtests: apply minor polish to test script
- Refactor kld loading/unloading logic:
-- Use a loop instead of an unrolled one.
-- Check for the module being loaded before trying to load it, to reduce
   noise when loading modules that are already loaded.
-- Don't mute stderr from kldload -- it could be potentially useful to
   the tester.
-- In the event that the test script was terminated early, it would leave
   the modules still attached to the system (which is undesirable).
   Always unload the modules at test end with EXIT/SIGINT/SIGTERM so the
   system is returned to its former operating state as best possible.
   Unload the modules in reverse order, in part for consistency and/or
   dependency reasons.

1de3fb0425 Fix up TEST_METADATA
- `TEST_METADATA.foo` should be `TEST_METADATA.run_tests`: this will unbreak
  trying to run the tests on a system without python installed in $PATH.
- The tests require root because they load aesni(4) and/or cryptodev(4) if
  not already loaded.

430f7286a5 Merge ^/user/ngie/release-pkg-fix-tests to unbreak how test files are installed
after r298107

Summary of changes:

- Replace all instances of FILES/TESTS with ${PACKAGE}FILES. This ensures that
  namespacing is kept with FILES appropriately, and that this shouldn't need
  to be repeated if the namespace changes -- only the definition of PACKAGE
  needs to be changed
- Allow PACKAGE to be overridden by callers instead of forcing it to always be
  `tests`. In the event we get to the point where things can be split up
  enough in the base system, it would make more sense to group the tests
  with the blocks they're a part of, e.g. byacc with byacc-tests, etc
- Remove PACKAGE definitions where possible, i.e. where FILES wasn't used
  previously.
- Remove unnecessary TESTSPACKAGE definitions; this has been elided into
  bsd.tests.mk
- Remove unnecessary BINDIRs used previously with ${PACKAGE}FILES;
  ${PACKAGE}FILESDIR is now automatically defined in bsd.test.mk.
- Fix installation of files under data/ subdirectories in lib/libc/tests/hash
  and lib/libc/tests/net/getaddrinfo
- Remove unnecessary .include <bsd.own.mk>s (some opportunistic cleanup)

Document the proposed changes in share/examples/tests/tests/... via examples
so it's clear that ${PACKAGES}FILES is the suggested way forward in terms of
replacing FILES. share/mk/bsd.README didn't seem like the appropriate method
of communicating that info.

08fca7a56b Add some new modes to OpenCrypto. These modes are AES-ICM (can be used
for counter mode), and AES-GCM.  Both of these modes have been added to
the aesni module.

Included is a set of tests to validate that the software and aesni
module calculate the correct values.  These use the NIST KAT test
vectors.  To run the test, you will need to install a soon to be
committed port, nist-kat that will install the vectors.  Using a port
is necessary as the test vectors are around 25MB.

All the man pages were updated.  I have added a new man page, crypto.7,
which includes a description of how to use each mode.  All the new modes
and some other AES modes are present.  It would be good for someone
else to go through and document the other modes.

A new ioctl was added to support AEAD modes which AES-GCM is one of them.
Without this ioctl, it is not possible to test AEAD modes from userland.

Add a timing safe bcmp for use to compare MACs.  Previously we were using
bcmp which could leak timing info and result in the ability to forge
messages.

Add a minor optimization to the aesni module so that single segment
mbufs don't get copied and instead are updated in place.  The aesni
module needs to be updated to support blocked IO so segmented mbufs
don't have to be copied.

We require that the IV be specified for all calls for both GCM and ICM.
This is to ensure proper use of these functions.
