Add test that changes ciphers on CCS

The TLS (pre-1.3) ChangeCipherState message is usually used to indicate
the switch from the unencrypted to encrypted part of the handshake.
However, it can also be used in cases where there is an existing
session (such as during resumption handshakes) or when changing from
one cipher to a different one (such as during renegotiation when the
cipher list offered by the client has changed).  This test serves
to exercise such situations, allowing us to detect whether session
objects are being modified in cases when they must remain immutable
for thread-safety purposes.

Code to thread-safety in ChangeCipherState

The server-side ChangeCipherState processing stores the new cipher
in the SSL_SESSION object, so that the new state can be used if
this session gets resumed.  However, writing to the session is only
thread-safe for initial handshakes, as at other times the session
object may be in a shared cache and in use by another thread at the
same time.  Reflect this invariant in the code by only writing to
s->session->cipher when it is currently NULL (we do not cache sessions
with no cipher).  The code prior to this change would never actually
change the (non-NULL) cipher value in a session object, since our
server enforces that (pre-TLS-1.3) resumptions use the exact same
cipher as the initial connection, and non-abbreviated renegotiations
have produced a new session object before we get to this point.
Regardless, include logic to detect such a condition and abort the
handshake if it occurs, to avoid any risk of inadvertently using
the wrong cipher on a connection.

6 months agoDon't write to the session when computing TLS 1.3 keys
Benjamin Kaduk [Fri, 24 Jan 2020 21:25:53 +0000 (13:25 -0800)]
Don't write to the session when computing TLS 1.3 keys

TLS 1.3 maintains a separate keys chedule in the SSL object, but
was writing to the 'master_key_length' field in the SSL_SESSION
when generating the per-SSL master_secret.  (The generate_master_secret
SSL3_ENC_METHOD function needs an output variable for the master secret
length, but the TLS 1.3 implementation just uses the output size of
the handshake hash function to get the lengths, so the only natural-looking
thing to use as the output length was the field in the session.
This would potentially involve writing to a SSL_SESSION object that was
in the cache (i.e., resumed) and shared with other threads, though.

The thread-safety impact should be minimal, since TLS 1.3 requires the
hash from the original handshake to be associated with the resumption
PSK and used for the subsequent connection.  This means that (in the
resumption case) the value being written would be the same value that was
previously there, so the only risk would be on architectures that can
produce torn writes/reads for aligned size_t values.

Since the value is essentially ignored anyway, just provide the
address of a local dummy variable to generate_master_secret() instead.

AES CTR-DRGB: performance improvement

Optimize the the AES-based implementation of the CTR_DRBG
construction, see 10.2.1 in [1].
Due to the optimizations, the code may deviate (more) from the
pseudocode in [1], but it is functional equivalence being decisive
for compliance:

"All DRBG mechanisms and algorithms are described in this document
in pseudocode, which is intended to explain functionality.
The pseudocode is not intended to constrain real-world
implementations." [9 in [1]].

The following optimizations are done:

- Replace multiple plain AES encryptions by a single AES-ECB
  encryption of a corresponding pre-initialized buffer, where
  This allows platform-specific AES-ECB support to
  be used and reduces the overhead of multiple EVP calls.

- Replace the generate operation loop (which is a counter
  increment followed by a plain AES encryption) by a
  loop which does a plain AES encryption followed by
  a counter increment. The latter loop is just a description
  of AES-CTR, so we replace it by a single AES-CTR
  This allows for platform-specific AES-CTR support to be used
  and reduces the overhead of multiple EVP calls.
  This change, that is, going from a pre- to a post- counter
  increment, requires the counter in the internal state
  to be kept at "+1" (compared to the pseudocode in [1])
  such that it is in the correct state, when a generate
  operation is called.
  That in turn also requires all other operations to be
  changed from pre- to post-increment to keep functional
