We broke this to varying degrees ages ago.
This is the logic to implement the variations of rules in TLS to discard
sessions after a failed connection, where a failed connection could be
one of:
- A connection that was not cleanly shut down.
- A connection that received a fatal alert.
The first one is nonsense since close_notify does not actually work in
the real world. The second is a vaguely more plausible but...
- A stateless ticket-based server can't drop sessions anyway.
- In TLS 1.3, a client may receive many tickets over the lifetime of a
single connection. With an external session cache like ours which may,
in theory, but multithreaded, this will be a huge hassle to track.
- A client may well attempt to establish a connection and reuse the
session before we receive the fatal alert, so any application state we
hope to manage won't really work.
- An attacker can always close the connection before the fatal alert, so
whatever security policy clearing the session gave is easily
bypassable.
Implementation-wise, this has basically never worked. The
ssl_clear_bad_session logic called into SSL_CTX_remove_session which
relied on the internal session cache. (Sessions not in the internal
session cache don't get removed.) The internal session cache was only
useful for a server, where tickets prevent this mechanism from doing
anything. For a client, we since removed the internal session cache, so
nothing got removed. The API for a client also did not work as it gave
the SSL_SESSION, not the SSL, so a consumer would not know the key to
invalidate anyway.
The recent session state splitting change further broke this.
Moreover, calling into SSL_CTX_remove_session logic like that is
extremely dubious because it mutates the not_resumable flag on the
SSL_SESSION which isn't thread-safe.
Spec-wise, TLS 1.3 has downgraded the MUST to a SHOULD.
Given all that mess, just remove this code. It is no longer necessary to
call SSL_shutdown just to make session caching work.

SSL_set_bio is a nightmare.
In f715c42322, we noticed that, among
other problems, SSL_set_bio's actual behavior did not match how
SSL_set_rfd was calling it due to an asymmetry in the rbio/wbio
handling. This resulted in SSL_set_fd/SSL_set_rfd calls to crash. We
decided that SSL_set_rfd's believed semantics were definitive and
changed SSL_set_bio.
Upstream, in 65e2d672548e7c4bcb28f1c5c835362830b1745b, decided that
SSL_set_bio's behavior, asymmetry and all, was definitive and that the
SSL_set_rfd crash was a bug in SSL_set_rfd. Accordingly, they switched
the fd callers to use the side-specific setters, new in 1.1.0.
Align with upstream's behavior and add tests for all of SSL_set_bio's
insanity. Also export the new side-specific setters in anticipation of
wanting to be mostly compatible with OpenSSL 1.1.0.

To prevent configuration/established session confusion, the handshake
session state is separated into the configured session (ssl->session)
and the newly created session (ssl->s3->new_session). Upon conclusion of
the handshake, the finalized session is stored
in (ssl->s3->established_session). During the handshake, any requests
for the session (SSL_get_session) return a non-resumable session, to
prevent resumption of a partially filled session. Sessions should only
be cached upon the completion of the full handshake, using the resulting
established_session. The semantics of accessors on the session are
maintained mid-renego.

This finishes getting rid of ssl_read_bytes! Now we have separate
entry-points for the various cases. For now, I've kept TLS handshake
consuming records partially. When we do the BIO-less API, I expect that
will need to change, since we won't have the record buffer available.
(Instead, the ssl3_read_handshake_bytes and extend_handshake_buffer pair
will look more like the DTLS side or Go and pull the entire record into
init_buf.)
This change opts to make read_app_data drive the message to completion
in anticipation of DTLS 1.3. That hasn't been specified, but
NewSessionTicket certainly will exist. Knowing that DTLS necessarily has
interleave seems something better suited for the SSL_PROTOCOL_METHOD
internals to drive.
It needs refining, but SSL_PROTOCOL_METHOD is now actually a half-decent
abstraction boundary between the higher-level protocol logic and
DTLS/TLS-specific record-layer and message dispatchy bits.

This is the equivalent of FragmentAcrossChangeCipherSuite for DTLS. It
is possible for us to, while receiving pre-CCS handshake messages, to
buffer up a message with sequence number meant for a post-CCS Finished.
When we then get to the new epoch and attempt to read the Finished, we
will process the buffered Finished although it was sent with the wrong
encryption.
Move ssl_set_{read,write}_state to SSL_PROTOCOL_METHOD hooks as this is
a property of the transport. Notably, read_state may fail. In DTLS
check the handshake buffer size. We could place this check in
read_change_cipher_spec, but TLS 1.3 has no ChangeCipherSpec message, so
we will need to implement this at the cipher change point anyway. (For
now, there is only an assert on the TLS side. This will be replaced with
a proper check in TLS 1.3.)

This isn't filled in on the client and Chromium no longer uses it for
plain RSA. It's redundant with existing APIs. This is part of removing
the need for callers to call SSL_get_session where possible.
SSL_get_session is ambiguous when it comes to renego. Some code wants
the current connection state which should not include the pending
handshake and some code wants the handshake scratch space which should.
Renego doesn't exist in TLS 1.3, but TLS 1.3 makes NewSessionTicket a
post-handshake message, so SSL_get_session is somewhat silly of an API
there too.
SSL_SESSION_get_key_exchange_info is a BoringSSL-only API, so we can
freely change it and replace it with APIs keyed on SSL. In doing so, I
think it is better to provide APIs like "SSL_get_dhe_group_size" and
"SSL_get_curve_id" rather than make the caller do the multi-step
SSL_get_current_cipher / SSL_CIPHER_is_ECDHE dance. To that end, RSA
key_exchange_info is pointless as it can already be determined from the

OpenSSL's SSL_OP_NO_* flags allow discontinuous version ranges. This is a
nuisance for two reasons. First it makes it unnecessarily difficult to answer
"are any versions below TLS 1.3 enabled?". Second the protocol does not allow
discontinuous version ranges on the client anyway. OpenSSL instead picks the
first continous range of enabled versions on the client, but not the server.
This is bizarrely inconsistent. It also doesn't quite do this as the
ClientHello sending logic does this, but not the ServerHello processing logic.
So we actually break some invariants slightly. The logic is also cumbersome in
DTLS which kindly inverts the comparison logic.
First, switch min_version/max_version's storage to normalized versions. Next
replace all the ad-hoc version-related functions with a single
ssl_get_version_range function. Client and server now consistently pick a
contiguous range of versions. Note this is a slight behavior change for
servers. Version-range-sensitive logic is rewritten to use this new function.
