Chrome uses the platform certificate verifier and thus cannot reliably
expect PSS signatures to work in all configurations. Add an API for the
consumer to inform BoringSSL of this ability. We will then adjust our
advertisements accordingly.
Note that, because TLS 1.2 does not have the signature_algorithms_cert
extension, turning off TLS 1.3 and using this API will stop advertising
RSA-PSS. I believe this is the correct behavior given the semantics of
that code point.
The tests check the various combinations here, as well as checking that
the peer never sends signature_algorithms_cert identical to
signature_algorithms.

The leaks not addressed by this CL are:

- The distribution of whether step 4.4 runs leaks information about w.
- We leak |a| (the largest power of two which divides w) everywhere.

On reflection, I think we'll need to note whether dummy PQ padding was

mixed with cases where people have MITM proxies that ignored the

Therefore this change will be used to filter latency measurements in
Chrome to only include those where the extension was echoed and we'll
measure at levels of 1 byte (for control), 400 bytes, and 1100 bytes.
This also makes it an error if the server didn't echo an extension of
the same length as was sent.

OpenSSL's RSA API is poorly designed and does not have a single place to
properly initialize the key. See
https://github.com/openssl/openssl/issues/5158.
To workaround this flaw, we must lazily instantiate pre-computed
Montgomery bits with locking. This is a ton of complexity. More
importantly, it makes it very difficult to implement RSA without side
channels. The correct in-memory representation of d, dmp1, and dmq1
depend on n, p, and q, respectively. (Those values have private
magnitudes and must be sized relative to the respective moduli.)
08805fe279 attempted to fix up the various
widths under lock, when we set up BN_MONT_CTX. However, this introduces
threading issues because other threads may access those exposed
components (RSA_get0_* also count as exposed for these purposes because
they are get0 functions), while a private key operation is in progress.
Instead, we do the following:
- There is no actual need to minimize n, p, and q, but we have minimized
copies in the BN_MONT_CTXs, so use those.
- Store additional copies of d, dmp1, and dmq1, at the cost of more
memory used. These copies have the correct width and are private,
unlike d, dmp1, and dmq1 which are sadly exposed. Fix private key
operations to use them.
- Move the frozen bit out of rsa->flags, as that too was historically
accessible without locking.
(Serialization still uses the original BIGNUMs, but the RSAPrivateKey
serialization format already inherently leaks the magnitude, so this
doesn't matter.)

Alas, the existence of RSA keys with q > p is obnoxious, but we can
canonicalize it away. To my knowledge, the remaining leaks in RSA are:
- Key generation. This is kind of hopelessly non-constant-time but
perhaps deserves a more careful ponder. Though hopefully it does not
come in at a measurable point for practical purposes.
- Private key serialization. RSAPrivateKey inherently leaks the
magnitudes of d, dmp1, dmq1, and iqmp. This is unavoidable but
hopefully does not come in at a measurable point for practical
purposes.
- If p and q have different word widths, we currently fall back to the
variable-time BN_mod rather than Montgomery reduction at the start of
CRT. I can think of ways to apply Montgomery reduction, but it's
probably better to deny CRT to such keys, if not reject them outright.
- bn_mul_fixed and bn_sqr_fixed which affect the Montgomery
multiplication bn_mul_mont-less configurations, as well as the final
CRT multiplication. We should fix this.

d, dmp1, dmq1, and iqmp have private magnitudes. This is awkward because
the RSAPrivateKey serialization leaks the magnitudes. Do the best we can
and fix them up before any RSA operations.
This moves the piecemeal BN_MONT_CTX_set_locked into a common function
where we can do more complex canonicalization on the keys. Ideally this
would be done on key import, but the exposed struct (and OpenSSL 1.1.0's
bad API design) mean there is no single point in time when key import is
finished.
Also document the constraints on RSA_set0_* functions. (These
constraints aren't new. They just were never documented before.)
Update-Note: If someone tried to use an invalid RSA key where d >= n,
dmp1 >= p, dmq1 >= q, or iqmp >= p, this may break. Such keys would not
have passed RSA_check_key, but it's possible to manually assemble
keys that bypass it.

Give a non-minimal modulus, there are two possible values of R we might
pick: 2^(BN_BITS2 * width) or 2^(BN_BITS2 * bn_minimal_width).
Potentially secret moduli would make the former attractive and things
might even work, but our only secret moduli (RSA) have public bit
widths. It's more cases to test and the usual BIGNUM invariant is that
widths do not affect numerical output.
Thus, settle on minimizing mont->N for now. With the top explicitly made
minimal, computing |lgBigR| is also a little simpler.
This CL also abstracts out the < R check in the RSA code, and implements

The private key callback may not push one of its own (it's possible to

completely wrong, as "syscall" really means "I don't know, something you

error, so this probably should as well.
Update-Note: Custom private key callbacks which push an error code on
failure will report both that error followed by
SSL_R_PRIVATE_KEY_OPERATION_FAILED. Callbacks which did not push any
error will switch from SSL_ERROR_SYSCALL to SSL_ERROR_SSL with

Mono's legacy TLS 1.0 stack, as a server, does not implement any form of
resumption, but blindly echos the ClientHello session ID in the
ServerHello for no particularly good reason.
This is invalid, but due to quirks of how our client checked session ID
equality, we only noticed on the second connection, rather than the
first. Flaky failures do no one any good, so break deterministically on
the first connection, when we realize something strange is going on.
