The DSA code is deprecated and will, hopefully, be removed in the future.
Nonetheless, this is easy enough to fix. It's the analog of the work we'd
already done for ECDSA.
- Document more clearly that we don't care about the DSA code.
- Use the existing constant-time modular addition function rather than
the ad-hoc code.
- Reduce the digest to satisfy modular operations' invariants. (The
underlying algorithms could accept looser bounds, but we reduce for
simplicity.) There's no particular reason to do this in constant time,
but we have the code for it, so we may as well.
- This additionally adds a missing check that num_bits(q) is a multiple
of 8. We otherwise don't compute the right answer. Verification
already rejected all 160-, 224-, and 256-bit keys, and we only
generate DSA parameters where the length of q matches some hash
function's length, so this is unlikely to cause anyone trouble.
- Use Montgomery reduction to perform the modular multiplication. This
could be optimized to save a couple Montgomery reductions as in ECDSA,
but DSA is deprecated, so I haven't bothered optimizing this.
- The reduction from g^k (mod p) to r = g^k (mod p) (mod q) is left
in variable time, but reversing it would require a discrete log
anyway. (The corresponding ECDSA operation is much easier to make
constant-time due to Hasse's theorem, though that's actually still a
TODO. I need to finish lifting EC_FELEM up the stack.)
Thanks to Keegan Ryan from NCC Group for reporting the modular addition issue
(CVE-2018-0495). The remainder is stuff I noticed along the way.
Update-Note: See the num_bits(q) change.

Although the original value of tmp does not matter, the selects
ultimately do bit operations on the uninitialized values and thus depend
on them behaving like *some* consistent concrete value. The C spec
appears to allow uninitialized values to resolve to trap
representations, which means this isn't quite valid..
(If I'm reading it wrong and the compiler must behave as if there were a
consistent value in there, it's probably fine, but there's no sense in
risking compiler bugs on a subtle corner of things.)

Update-Note: This tweaks the SSL_shutdown behavior. OpenSSL's original
SSL_shutdown behavior was an incoherent mix of discarding the record and
rejecting it (it would return SSL_ERROR_SYSCALL but retrying the
operation would discard it). SSLeay appears to have intended to discard
it, so we previously "fixed" it actually discard.
However, this behavior is somewhat bizarre and means we skip over
unbounded data, which we typically try to avoid. If you are trying to
cleanly shutdown the TLS portion of your protocol, surely it is at a
point where additional data is a syntax error. I suspect I originally
did not realize that, because the discarded record did not properly
continue the loop, SSL_shutdown would appear as if it rejected the data,
and so it's unlikely anyone was relying on that behavior.
Discussion in https://github.com/openssl/openssl/pull/6340 suggests
(some of) upstream also prefers rejecting.

|alloca| is dangerous and poorly specified, according to any
description of |alloca|. It's also hard for some analysis tools to
reason about.
The code here assumed |alloca| is a macro, which isn't a valid
assumption. Depending on what which headers are included and what
toolchain is being used, |alloca| may or may not be defined as a macro,
and this might change over time if/when toolchains are updated. Or, we
might be doing static analysis and/or dynamic analysis with a different
configuration w.r.t. the availability of |alloca| than production
builds use.
Regardless, the |alloca| code path only kicked in when the inputs are
840 bits or smaller. Since the multi-prime RSA support was removed, for
interesting RSA key sizes the input will be at least 1024 bits and this
code path won't be triggered since powerbufLen will be larger than 3072
bytes in those cases. ECC inversion via Fermat's Little Theorem has its
own constant-time exponentiation so there are no cases where smaller
inputs need to be fast.
The RSAZ code avoids the |OPENSSL_malloc| for 2048-bit RSA keys.
Increasingly the RSAZ code won't be used though, since it will be
skipped over on Broadwell+ CPUs. Generalize the RSAZ stack allocation
to work for non-RSAZ code paths. In order to ensure this doesn't cause
too much stack usage on platforms where RSAZ wasn't already being used,
only do so on x86-64, which already has this large stack size
requirement due to RSAZ.
This change will make it easier to refactor |BN_mod_exp_mont_consttime|
to do that more safely and in a way that's more compatible with various
analysis tools.
This is also a step towards eliminating the |uintptr_t|-based alignment
hack.
Since this change increases the number of times |OPENSSL_free| is
skipped, I've added an explicit |OPENSSL_cleanse| to ensure the
zeroization is done. This should be done regardless of the other changes
here.

cryptography.io wants RSA_R_BLOCK_TYPE_IS_NOT_02, only used by the
ancient RSA_padding_check_SSLv23 function. Define it but never emit it.
Additionally, it's rather finicky about RSA_R_TOO_LARGE* errors. We
merged them in BoringSSL because having RSA_R_TOO_LARGE,
RSA_R_TOO_LARGE_FOR_MODULUS, and RSA_R_TOO_LARGE_FOR_KEY_SIZE is a
little silly. But since we don't expect well-behaved code to condition
on error codes anyway, perhaps that wasn't worth it. Split them back
up.
Looking through OpenSSL, there is a vague semantic difference:
RSA_R_DIGEST_TOO_BIG_FOR_RSA_KEY - Specifically emitted if a digest is
too big for PKCS#1 signing with this key.
RSA_R_DATA_TOO_LARGE_FOR_KEY_SIZE - You asked me to sign or encrypt a
digest/plaintext, but it's too big for this key.
RSA_R_DATA_TOO_LARGE_FOR_MODULUS - You gave me an RSA ciphertext or
signature and it is not fully reduced modulo N.
-OR-
The padding functions produced something that isn't reduced, but I
believe this is unreachable outside of RSA_NO_PADDING.
RSA_R_DATA_TOO_LARGE - Some low-level padding function was told to copy
a digest/plaintext into some buffer, but the buffer was too small. I
think this is basically unreachable.
-OR-
You asked me to verify a PSS signature, but I didn't need to bother
because the digest/salt parameters you picked were too big.
Update-Note: This depends on cl/196566462.

If the callback returns an empty ALPN, we forget we negotiated ALPN at
all (bssl::Array does not distinguish null and empty). Empty ALPN
protocols are forbidden anyway, so reject these ahead of time.

It's conditioned in OpenSSL on client offer, not server accept.
