After allocation, output and decomp_output both point to memory chunks of
size COMP_BUF_SIZE. Then, only the first bytes are zeroed out using
sizeof(COMP_BUF_SIZE) as parameter to memset(), because
sizeof(COMP_BUF_SIZE) provides the size of the constant and not the size of
allocated memory.
Instead, the whole allocated memory is meant to be zeroed out. Use
COMP_BUF_SIZE as parameter to memset() directly in order to accomplish
this.

Remove the original version of the VMAC template that had the nonce
hardcoded to 0 and produced a digest with the wrong endianness. I'm
unsure whether this had users or not (there are no explicit in-kernel
references to it), but given that the hardcoded nonce made it wildly
insecure unless a unique key was used for each message, let's try
removing it and see if anyone complains.
Leave the new "vmac64" template that requires the nonce to be explicitly
specified as the first 16 bytes of data and uses the correct endianness
for the digest.

Currently the VMAC template uses a "nonce" hardcoded to 0, which makes
it insecure unless a unique key is set for every message. Also, the
endianness of the final digest is wrong: the implementation uses little
endian, but the VMAC specification has it as big endian, as do other
VMAC implementations such as the one in Crypto++.
Add a new VMAC template where the nonce is passed as the first 16 bytes
of data (similar to what is done for Poly1305's nonce), and the digest
is big endian. Call it "vmac64", since the old name of simply "vmac"
didn't clarify whether the implementation is of VMAC-64 or of VMAC-128
(which produce 64-bit and 128-bit digests respectively); so we fix the
naming ambiguity too.

Currently testmgr has separate encryption and decryption test vectors
for symmetric ciphers. That's massively redundant, since with few
exceptions (mostly mistakes, apparently), all decryption tests are
identical to the encryption tests, just with the input/result flipped.
Therefore, eliminate the redundancy by removing the decryption test
vectors and updating testmgr to test both encryption and decryption
using what used to be the encryption test vectors. Naming is adjusted
accordingly: each cipher_testvec now has a 'ptext' (plaintext), 'ctext'
(ciphertext), and 'len' instead of an 'input', 'result', 'ilen', and
'rlen'. Note that it was always the case that 'ilen == rlen'.
AES keywrap ("kw(aes)") is special because its IV is generated by the
encryption. Previously this was handled by specifying 'iv_out' for
encryption and 'iv' for decryption. To make it work cleanly with only
one set of test vectors, put the IV in 'iv', remove 'iv_out', and add a
boolean that indicates that the IV is generated by the encryption.
In total, this removes over 10000 lines from testmgr.h, with no
reduction in test coverage since prior patches already copied the few
unique decryption test vectors into the encryption test vectors.
This covers all algorithms that used 'struct cipher_testvec', e.g. any
block cipher in the ECB, CBC, CTR, XTS, LRW, CTS-CBC, PCBC, OFB, or
keywrap modes, and Salsa20 and ChaCha20. No change is made to AEAD
tests, though we probably can eliminate a similar redundancy there too.
The testmgr.h portion of this patch was automatically generated using
the following awk script, with some slight manual fixups on top (updated
'struct cipher_testvec' definition, updated a few comments, and fixed up
the AES keywrap test vectors):
BEGIN { OTHER = 0; ENCVEC = 1; DECVEC = 2; DECVEC_TAIL = 3; mode = OTHER }
/^static const struct cipher_testvec.*_enc_/ { sub("_enc", ""); mode = ENCVEC }
/^static const struct cipher_testvec.*_dec_/ { mode = DECVEC }
mode == ENCVEC && !/\.ilen[[:space:]]*=/ {
sub(/\.input[[:space:]]*=$/, ".ptext =")
sub(/\.input[[:space:]]*=/, ".ptext\t=")
sub(/\.result[[:space:]]*=$/, ".ctext =")
sub(/\.result[[:space:]]*=/, ".ctext\t=")
sub(/\.rlen[[:space:]]*=/, ".len\t=")
print
}
mode == DECVEC_TAIL && /[^[:space:]]/ { mode = OTHER }
mode == OTHER { print }
mode == ENCVEC && /^};/ { mode = OTHER }
mode == DECVEC && /^};/ { mode = DECVEC_TAIL }
Note that git's default diff algorithm gets confused by the testmgr.h
portion of this patch, and reports too many lines added and removed.
It's better viewed with 'git diff --minimal' (or 'git show --minimal'),
which reports "2 files changed, 919 insertions(+), 11723 deletions(-)".

Since testmgr uses a single tfm for all tests of each hash algorithm,
once a key is set the tfm won't be unkeyed anymore. But with crc32 and
crc32c, the key is really the "default initial state" and is optional;
those algorithms should have both keyed and unkeyed test vectors, to
verify that implementations use the correct default key.
Simply listing the unkeyed test vectors first isn't guaranteed to work
yet because testmgr makes multiple passes through the test vectors.
crc32c does have an unkeyed test vector listed first currently, but it
only works by chance because the last crc32c test vector happens to use
a key that is the same as the default key.
Therefore, teach testmgr to split hash test vectors into unkeyed and
keyed sections, and do all the unkeyed ones before the keyed ones.

Enable CryptoCell support for hardware keys.
Hardware keys are regular AES keys loaded into CryptoCell internal memory
via firmware, often from secure boot ROM or hardware fuses at boot time.
As such, they can be used for enc/dec purposes like any other key but
cannot (read: extremely hard to) be extracted since since they are not
available anywhere in RAM during runtime.
The mechanism has some similarities to s390 secure keys although the keys
are not wrapped or sealed, but simply loaded offline. The interface was
therefore modeled based on the s390 secure keys support.

Different compression engines like the ThunderX ZIP coprocessor
might yield different compression results by tuning the

Add a generic implementation of Speck, including the Speck128 and
Speck64 variants. Speck is a lightweight block cipher that can be much
faster than AES on processors that don't have AES instructions.
We are planning to offer Speck-XTS (probably Speck128/256-XTS) as an
option for dm-crypt and fscrypt on Android, for low-end mobile devices
with older CPUs such as ARMv7 which don't have the Cryptography
Extensions. Currently, such devices are unencrypted because AES is not
fast enough, even when the NEON bit-sliced implementation of AES is
used. Other AES alternatives such as Twofish, Threefish, Camellia,
CAST6, and Serpent aren't fast enough either; it seems that only a
modern ARX cipher can provide sufficient performance on these devices.
This is a replacement for our original proposal
(https://patchwork.kernel.org/patch/10101451/) which was to offer
ChaCha20 for these devices. However, the use of a stream cipher for
disk/file encryption with no space to store nonces would have been much
more insecure than we thought initially, given that it would be used on
top of flash storage as well as potentially on top of F2FS, neither of
which is guaranteed to overwrite data in-place.
Speck has been somewhat controversial due to its origin. Nevertheless,
it has a straightforward design (it's an ARX cipher), and it appears to
be the leading software-optimized lightweight block cipher currently,
with the most cryptanalysis. It's also easy to implement without side
channels, unlike AES. Moreover, we only intend Speck to be used when
the status quo is no encryption, due to AES not being fast enough.
We've also considered a novel length-preserving encryption mode based on
ChaCha20 and Poly1305. While theoretically attractive, such a mode
would be a brand new crypto construction and would be more complicated
and difficult to implement efficiently in comparison to Speck-XTS.
There is confusion about the byte and word orders of Speck, since the
original paper doesn't specify them. But we have implemented it using
the orders the authors recommended in a correspondence with them. The
test vectors are taken from the original paper but were mapped to byte
arrays using the recommended byte and word orders.

The CPU Jitter RNG provides a source of good entropy by
collecting CPU executing time jitter. The entropy in the CPU
execution time jitter is magnified by the CPU Jitter Random
Number Generator. The CPU Jitter Random Number Generator uses
the CPU execution timing jitter to generate a bit stream
which complies with different statistical measurements that
determine the bit stream is random.
The CPU Jitter Random Number Generator delivers entropy which
follows information theoretical requirements. Based on these
studies and the implementation, the caller can assume that
one bit of data extracted from the CPU Jitter Random Number
Generator holds one bit of entropy.
The CPU Jitter Random Number Generator provides a decentralized
source of entropy, i.e. every caller can operate on a private
state of the entropy pool.
The RNG does not have any dependencies on any other service
in the kernel. The RNG only needs a high-resolution time
stamp.
Further design details, the cryptographic assessment and
large array of test results are documented at
http://www.chronox.de/jent.html.

Patch adds AVX2/x86-64 implementation of Twofish cipher, requiring 16 parallel
blocks for input (256 bytes). Table look-ups are performed using vpgatherdd
instruction directly from vector registers and thus should be faster than
earlier implementations. Implementation also uses 256-bit wide YMM registers,
which should give additional speed up compared to the AVX implementation.

fcrypt is used only as pcbc(fcrypt), but testmgr does not know this.
Use the zero key, zero plaintext pcbc(fcrypt) test vector for
testing plain 'fcrypt' to hide "no test for fcrypt" warnings.

When in fips mode, compression algoritms fails to initialize,
e.g. modprobe ubifs returns
UBIFS error: compr_init: cannot initialize compressor lzo, error -2
FIPS mode should not care about compression algoritms at all.
Patch just set fips_enabled flag to 1 to all compression algorithms
managed by testmgr.

Most DES3_EDE testvectors are short and do not test parallelised codepaths
well. Add larger testvectors to test large crypto operations and to test
multi-page crypto with DES3_EDE.

Currrently test_aead uses same buffer for destination and source. However
in any places, 'dst != src' take different path than 'dst == src' case.
Therefore make test_aead also run tests with destination buffer being
different than source buffer.

Patch 863b557a88 added NULL entries
for intel accelerated drivers but did not marked these fips allowed.
This cause panic if running tests with fips=1.
For ghash, fips_allowed flag was added in patch
18c0ebd2d8.
Without patch, "modprobe tcrypt" fails with
alg: skcipher: Failed to load transform for cbc-aes-aesni: -2
cbc-aes-aesni: cbc(aes) alg self test failed in fips mode!
(panic)
Also add missing cryptd(__driver-cbc-aes-aesni) and
cryptd(__driver-gcm-aes-aesni) test to complement
null tests above, otherwise system complains with
alg: No test for __cbc-aes-aesni (cryptd(__driver-cbc-aes-aesni))
alg: No test for __gcm-aes-aesni (cryptd(__driver-gcm-aes-aesni))
