Allow certificates with Basic Constraints CA:false, pathlen:0

Do not mark such certificates with EXFLAG_INVALID although they
violate the RFC 5280, they are syntactically correct and
openssl itself can produce such certificates without any errors
with command such as:

openssl x509 -req -signkey private.pem -in csr.pem -out cert.pem \
  -extfile <(echo "basicConstraints=CA:FALSE,pathlen:0")

With the commit ba4356ae4002a04e28642da60c551877eea804f7 the
EXFLAG_INVALID causes openssl to not consider such certificate
even as leaf self-signed certificate which is breaking existing
installations.

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.

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.

Detect EOF while reading in libssl

If we hit an EOF while reading in libssl then we will report an error
back to the application (SSL_ERROR_SYSCALL) but errno will be 0. We add
an error to the stack (which means we instead return SSL_ERROR_SSL) and
therefore give a hint as to what went wrong.

Do not silently truncate files on perlasm errors

If one of the perlasm xlate drivers crashes, OpenSSL's build will
currently swallow the error and silently truncate the output to however
far the driver got. This will hopefully fail to build, but better to
check such things.

Handle this by checking for errors when closing STDOUT (which is a pipe

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.

OpenSSL::Test: bring back the relative paths

Because there was a bug in File::Spec::Unix' abs2rel when it was given
relative paths as both PATH and BASE arguments, the directories we
deal with were made to be all absolute.  Unfortunately, this meant
getting paths in our verbose test output which are difficult to use
anywhere else (such as a separate test build made for comparison), due
to the constant need to edit all the paths all the time.

We're therefore getting back the relative paths, by doing an extra
abs2rel() in __srctop_file, __srctop_dir, __bldtop_file and
__bldtop_dir, with a 'Cwd::getcwd' call as BASE argument.

Replace apps/server.pem with certificate with a sha256 signature.

It replaces apps/server.pem that used a sha1 signature with a copy of
test/certs/servercert.pem that is uses sha256.

This caused the dtlstest to start failing. It's testing connection
sbetween a dtls client and server. In particular it was checking that if
we drop a record that the handshake recovers and still completes
successfully. The test iterates a number of times. The first time
through it drops the first record. The second time it drops the second
one, and so on. In order to do this it has a hard-coded value for the
expected number of records it should see in a handshake. That's ok
because we completely control both sides of the handshake and know what
records we expect to see. Small changes in message size would be
tolerated because that is unlikely to have an impact on the number of
records. Larger changes in message size however could increase or
decrease the number of records and hence cause the test to fail.

This particular test uses a mem bio which doesn't have all the CTRLs
that the dgram BIO has. When we are using a dgram BIO we query that BIO
to determine the MTU size. The smaller the MTU the more fragmented
handshakes become. Since the mem BIO doesn't report an MTU we use a
rather small default value and get quite a lot of records in our
handshake. This has the tendency to increase the likelihood of the
number of records changing in the test if the message size changes.

It so happens that the new server certificate is smaller than the old
one. AFAICT this is probably because the DNs for the Subject and Issuer
are significantly shorter than previously. The result is that the number
of records used to transmit the Certificate message is one less than it
was before. This actually has a knock on impact for subsequent messages
and how we fragment them resulting in one less ServerKeyExchange record
too (the actual size of the ServerKeyExchange message hasn't changed,
but where in that message it gets fragmented has). In total the number
of records used in the handshake has decreased by 2 with the new
server.pem file.

called with a NULL key and an explicit md is provided which is the same as
the md that was provided previously. But in that case we can actually reuse
the pre-digested key that we calculated last time, so we can refactor the
code not to use the stored key at all.

With that refactor done it is no longer necessary to store the key in the
ctx at all. This means that long running ctx's will not keep the key in
memory for any longer than required. Note though that the digested key
*is* still kept in memory for the duration of the life of the ctx.

Fix incorrect return code on ECDSA key verification

ECDSA_do_verify() is a function that verifies a ECDSA signature given a hash and a public EC key. The function is supposed to return 1 on valid signature, 0 on invalid signature and -1 on error. Previously, we returned 0 if the key did not have a verify_sig method. This is actually an error case and not an invalid signature. Consequently, this patch updates the return code to -1.

Fixes #8766

This commit addresses a potential side-channel vulnerability in the

The side-channel leakage appears to be tiny, so the severity of this
