09b90e0ed7 Introducing option SSL_OP_IGNORE_UNEXPECTED_EOF
Partially fixes #11209.

Before OpenSSL 3.0 in case when peer does not send close_notify,
the behaviour was to set SSL_ERROR_SYSCALL error with errno 0.
This behaviour has changed. The SSL_OP_IGNORE_UNEXPECTED_EOF restores
the old behaviour for compatibility's sake.

d30ef63964 Correct alignment calculation in ssl3_setup_write
The alignment calculation in ssl3_setup_write incorrectly results in an
alignment allowance of
(-SSL3_RT_HEADER_LENGTH) & (SSL3_ALIGN_PAYLOAD - 1) bytes. This equals 3
in almost all cases. The maximum alignment actually used in do_ssl3_write
is (SSL3_ALIGN_PAYLOAD - 1). This equals 7 bytes in almost all cases. So
there is a potential to overrun the buffer by up to 4 bytes.

Fortunately, the encryption overhead allowed for is 80 bytes which
consists of 16 bytes for the cipher block size and 64 bytes for the MAC
output. However the biggest MAC that we ever produce is HMAC-384 which is
48 bytes - so we have a headroom of 16 bytes (i.e. more than the 4 bytes
of potential overrun).

Thanks to Nagesh Hegde for reporting this.

Fixes #11766

We were not correctly detecting whether TLSv1.3 ciphersuites could
actually be supported by the available provider implementations. For
example a FIPS client would still offer CHACHA20-POLY1305 based
ciphersuites even though it couldn't actually use them. Similarly on
the server would try to use CHACHA20-POLY1305 and then fail the

a87f3fe01a Fix NULL dereference in SSL_check_chain() for TLS 1.3
In the tls1_check_sig_alg() helper function, we loop through the list of
"signature_algorithms_cert" values received from the client and attempt
to look up each one in turn in our internal table that maps wire
codepoint to string-form name, digest and/or signature NID, etc., in
order to compare the signature scheme from the peer's list against what
is used to sign the certificates in the certificate chain we're
checking.  Unfortunately, when the peer sends a value that we don't
support, the lookup returns NULL, but we unconditionally dereference the
lookup result for the comparison, leading to an application crash
triggerable by an unauthenticated client.

Since we will not be able to say anything about algorithms we don't
recognize, treat NULL return from lookup as "does not match".

We currently only apply the "signature_algorithm_cert" checks on TLS 1.3
connections, so previous TLS versions are unaffected.  SSL_check_chain()
is not called directly from libssl, but may be used by the application
inside a callback (e.g., client_hello or cert callback) to verify that a
candidate certificate chain will be acceptable to the client.

074a6e86e6 Use a flag in SSL3_BUFFER to track when an application buffer is reused.
With KTLS, writes to an SSL connection store the application buffer
pointer directly in the 'buf' member instead of allocating a separate
buffer to hold the encrypted data.  As a result,
ssl3_release_write_buffer() has to avoid freeing these 'buf' pointers.

Previously, ssl3_release_write_buffer() checked for KTLS being enabled
on the write BIO to determine if a buffer should be freed.  However, a
buffer can outlive a BIO.  For example, 'openssl s_time' creates new
write BIOs when reusing sessions.  Since the new BIO did not have KTLS
enabled at the start of a connection, ssl3_release_write_buffer()
would incorrectly try to free the 'buf' pointer from the previous KTLS
connection.  To fix, track the state of 'buf' explicitly in
SSL3_BUFFER to determine if the 'buf' should be freed or simply
cleared.

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.

d74014c4b8 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.

7955c1f16e Fix SSL_get_servername() and SNI behaviour
The SNI behaviour for TLSv1.3 and the behaviour of SSL_get_servername()
was not quite right, and not entirely consistent with the RFC.

The TLSv1.3 RFC explicitly says that SNI is negotiated on each handshake
and the server is not required to associate it with the session. This was
not quite reflected in the code so we fix that.

Additionally there were some additional checks around early_data checking
that the SNI between the original session and this session were
consistent. In fact the RFC does not require any such checks, so they are
removed.

Finally the behaviour of SSL_get_servername() was not quite right. The
behaviour was not consistent between resumption and normal handshakes,
and also not quite consistent with historical behaviour. We clarify the
behaviour in various scenarios and also attempt to make it match historical
behaviour as closely as possible.

2a53855110 Fix a race condition in SNI handling
As was done for ciphers, supported groups, and EC point formats in
https://github.com/openssl/openssl/pull/9162, only write the negotiated
SNI hostname value to the session object when not resuming, even for
TLS 1.3 resumptions.  Otherwise, when using a stateful session cache
(as is done by default when 0-RTT data is enabled), we can have multiple
SSLs active using the same in-memory session object, which leads to
double-frees and similar race conditions in the SNI handler prior
to this commit.

Fortunately, since draft-ietf-tls-tls13-22, there is no requirement
that the SNI hostname be preserved across TLS 1.3 resumption, and thus
not a need to continually update the session object with the "current"
value (to be used when producing session tickets, so that the subsequent
resumption can be checked against the current value).  So we can just
relax the logic and only write to the session object for initial handshakes.
This still leaves us in a somewhat inconsistent state, since if the SNI value
does change across handshakes, the session object will continue to record
the initial handshake's value, even if that bears no relation to the
current handshake.  The current SSL_get_servername() implementation
prefers the value from the session if s->hit, but a more complete fix
for that and related issues is underway in
https://github.com/openssl/openssl/pull/10018; there is no need to wait
for the complete fix for SNI name handling in order to close the
race condition and avoid runtime crashes.
