See the comments in the code for how an attack would go, and the ChangeLog
entry for an impact assessment. (For ECDSA, leaking a few bits of the scalar
over several signatures translates to full private key recovery using a

Manuel Pégourié-Gonnard b08a3344a5 Improve debug logging of client hard reconnect
The current logging was sub-standard, in particular there was no trace
whatsoever of the HelloVerifyRequest being sent. Now it's being logged with
the usual levels: 4 for full content, 2 return of f_send, 1 decision about
sending it (or taking other branches in the same function) because that's the
same level as state changes in the handshake, and also same as the "possible
client reconnect" message" to which it's the logical continuation (what are we
doing about it?).

Gilles Peskine e8caf2634b Since unmet_dependencies stores integers, represent them as int
Since unmet_dependencies only ever contains strings that are integers
written out in decimal, store the integer instead. Do this
unconditionally since it doesn't cost any extra memory.

This commit saves a little memory and more importantly avoids a gotcha
with uninitialized pointers which caused a bug on development (the
array was only initialized in verbose mode).

Manuel Pégourié-Gonnard 34cbf106f3 Adjust timeout of tests with "no resend" assertions
There are currently 4 tests in ssl-opt.sh with either -C "resend" or -S
"resend", that is, asserting that no retransmission will occur. They sometimes
fail on loaded CI machines as one side doesn't send a message fast enough,
causing the other side to retransmit, causing the test to fail.

(For the "reconnect" test there was an other issue causing random failures,
fixed in a previous commit, but even after that fix the test would still
sometimes randomly fail, even if much more rarely.)

While it's a hard problem to fix in a general and perfect way, in practice the
probability of failures can be drastically reduced by making the timeout
values much larger.

For some tests, where retransmissions are actually expected, this would have
the negative effect of increasing the average running time of the test, as
each side would wait for longer before it starts retransmission, so we have a
trade-off between average running time and probability of spurious failures.

But for tests where retransmission is not expected, there is no such trade-off
as the expected running time of the test (assuming the code is correct most of
the time) is not impacted by the timeout value. So the only negative effect of
increasing the timeout value is on the worst-case running time on the test,
which is much less important, as test should only fail quite rarely.

This commit addresses the easy case of tests that don't expect retransmission
by increasing the value of their timeout range to 10s-20s. This value
corresponds to the value used for tests that assert `-S "autoreduction"` which
are in the same case and where the current value seems acceptable so far.

It also represents an increase, compared to the values before this commit, of
a factor 20 for the "reconnect" tests which were frequently observed to fail
in the CI, and of a factor 10 for the first two "DTLS proxy" tests, which were
observed to fail much less frequently, so hopefully the new values are enough
to reduce the probability of spurious failures to an acceptable level.

Manuel Pégourié-Gonnard b85ce9eaeb Add negative test for hard reconnect cookie check
The server must check client reachability (we chose to do that by checking a
cookie) before destroying the existing association (RFC 6347 section 4.2.8).
Let's make sure we do, by having a proxy-in-the-middle inject a ClientHello -
the server should notice, but not destroy the connection.

Simon Butcher 5cc087945a Correct comment on the configuration option in x509.c
In x509.c, the self-test code is dependent on MBEDTLS_CERTS_C and
MBEDTLS_SHA256_C being enabled. At some point in the recent past that dependency
was on MBEDTLS_SHA1_C but changed to SHA256, but the comment wasn't updated.

This commit updates the comment.

Simon Butcher 14ba0ce43b Add additional sanity checks to check_config.h
Additional sanity checks in check_config.h to ensure:
    * if test certificates are included (MBEDTLS_CERTS_C) there must be also be
      support for the core X509 feature (MBEDTLS_X509_USE_C). This has a
      secondary dependency on the public key abstraction layer (MBEDTLS_PK_C),
      necessary as the certificates will either be signed by RSA or ECDSA, and
      therefore need to be part of the library.
    * if any of the TLS protocols are defined (MBEDTLS_SSL_PROTO_xxx) then a
      key exchange method must also be defined (MBEDTLS_KEY_EXCHANGE_xxx).

Anyone who knows the library will probably not make these mistakes or will
quickly diagnose and fix them, but it is possible to compile and link both
configurations if you build only the library and not the example programs, and
therefore users may not realise immediately that there's a mistake, only
discovering it at runtime.

These checks may therefore save someone some time.

Simon Butcher 47f728718f Change the use of pylint to optionally use pylint3
Pylint when installed as a distro package can be installed as pylint3, whilst as
a PEP egg, it can be installed as pylint.

This commit changes the scripts to first use pylint if installed, and optionally
look for pylint3 if not installed. This is to allow a preference for the PEP
version over the distro version, assuming the PEP one is more likely to be
the correct one.

strip out the config line, and then to select only the pylint line.
