keccakf() is the only function in kernel that uses __optimize() macro.
__optimize() breaks frame pointer unwinder as optimized code uses RBP,
and amusingly this always lead to degraded performance as gcc does not
inline across different optimizations levels, so keccakf() wasn't inlined
into its callers and keccakf_round() wasn't inlined into keccakf().
Drop __optimize() to resolve both problems.

This reverts commit eb772f37ae, as now the
x86 Salsa20 implementation has been removed and the generic helpers are
no longer needed outside of salsa20_generic.c.
We could keep this just in case someone else wants to add a new
optimized Salsa20 implementation. But given that we have ChaCha20 now
too, I think it's unlikely. And this can always be reverted back.

The x86 assembly implementations of Salsa20 use the frame base pointer
register (%ebp or %rbp), which breaks frame pointer convention and
breaks stack traces when unwinding from an interrupt in the crypto code.
Recent (v4.10+) kernels will warn about this, e.g.
WARNING: kernel stack regs at 00000000a8291e69 in syzkaller047086:4677 has bad 'bp' value 000000001077994c
[...]
But after looking into it, I believe there's very little reason to still
retain the x86 Salsa20 code. First, these are *not* vectorized
(SSE2/SSSE3/AVX2) implementations, which would be needed to get anywhere
close to the best Salsa20 performance on any remotely modern x86
processor; they're just regular x86 assembly. Second, it's still
unclear that anyone is actually using the kernel's Salsa20 at all,
especially given that now ChaCha20 is supported too, and with much more
efficient SSSE3 and AVX2 implementations. Finally, in benchmarks I did
on both Intel and AMD processors with both gcc 8.1.0 and gcc 4.9.4, the
x86_64 salsa20-asm is actually slightly *slower* than salsa20-generic
(~3% slower on Skylake, ~10% slower on Zen), while the i686 salsa20-asm
is only slightly faster than salsa20-generic (~15% faster on Skylake,
~20% faster on Zen). The gcc version made little difference.
So, the x86_64 salsa20-asm is pretty clearly useless. That leaves just
the i686 salsa20-asm, which based on my tests provides a 15-20% speed
boost. But that's without updating the code to not use %ebp. And given
the maintenance cost, the small speed difference vs. salsa20-generic,
the fact that few people still use i686 kernels, the doubt that anyone
is even using the kernel's Salsa20 at all, and the fact that a SSE2
implementation would almost certainly be much faster on any remotely
modern x86 processor yet no one has cared enough to add one yet, I don't
think it's worthwhile to keep.
Thus, just remove both the x86_64 and i686 salsa20-asm implementations.

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 }

portion of this patch, and reports too many lines added and removed.

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.

In do_chtls_setsockopt(), the tls crypto info is first copied from the
poiner 'optval' in userspace and saved to 'tmp_crypto_info'. Then the
'version' of the crypto info is checked. If the version is not as expected,
i.e., TLS_1_2_VERSION, error code -ENOTSUPP is returned to indicate that
the provided crypto info is not supported yet. Then, the 'cipher_type'
field of the 'tmp_crypto_info' is also checked to see if it is
TLS_CIPHER_AES_GCM_128. If it is, the whole struct of
tls12_crypto_info_aes_gcm_128 is copied from the pointer 'optval' and then
the function chtls_setkey() is invoked to set the key.
Given that the 'optval' pointer resides in userspace, a malicious userspace
process can race to change the data pointed by 'optval' between the two
copies. For example, a user can provide a crypto info with TLS_1_2_VERSION
and TLS_CIPHER_AES_GCM_128. After the first copy, the user can modify the
'version' and the 'cipher_type' fields to any versions and/or cipher types
that are not allowed. This way, the user can bypass the checks, inject
bad data to the kernel, cause chtls_setkey() to set a wrong key or other
issues.
This patch reuses the data copied in the first try so as to ensure these
checks will not be bypassed.
