Gilles Peskine b9d0fd60e4 Travis: split the build into three parallel jobs
Split the build between:
* Basic checks
* A build in the default configuration with extensive tests
* Builds in other configurations with less testing

The intent is to have one shorter job with basic tests, and two longer
jobs that take roughly the same amount of time (split as evenly as
possible while keeping an easy-to-understand separation).

Gilles Peskine e021233cbc Travis: don't test with both gcc and clang
In practice, we hardly ever get different outcomes, so there is no
gain in running tests with different compilers.

Experimentally, with the builds and tests we currently do and with the
compiler versions on a Travis Ubuntu 16.04, gcc jobs are significantly
faster than clang jobs (13 min vs 24 min). So use gcc.

Backport 2.7: Guard from undefined behaviour in case of an INT_MAX max_pathlen
2020-04-17 14:24:45 +01:00
Andrzej Kurek 3fd9297658 Guard from undefined behaviour in case of an INT_MAX max_pathlen
When parsing a certificate with the basic constraints extension
the max_pathlen that was read from it was incremented regardless
of its value. However, if the max_pathlen is equal to INT_MAX (which
is highly unlikely), an undefined behaviour would occur.
This commit adds a check to ensure that such value is not accepted
as valid. Relevant tests for INT_MAX and INT_MAX-1 are also introduced.
Certificates added in this commit were generated using the
test_suite_x509write, function test_x509_crt_check. Input data taken
from the "Certificate write check Server1 SHA1" test case, so the generated
files are like the "server1.crt", but with the "is_ca" field set to 1 and
max_pathlen as described by the file name.

Manuel Pégourié-Gonnard 5408f72027 Fix integer overflow in benchmark program
When building with MBEDTLS_MEMORY_DEBUG enabled, and running the ecdh part,
the benchmark program would start writing a very large number of space
characters on stdout, and would have to be killed because it never seemed to
terminate.

This was due to an integer overflow in computing how many space to leave after
the title in order to get memory measurements aligned, which resulted in up
to SIZE_MAX spaces being printed.

This commit just fixes the overflow, the next commit is going to fix the magic
number (12).

Manuel Pégourié-Gonnard 6062b49d29 Fix bug in handling of DTLS client hard reconnect
We keep track of the current epoch and record sequence number in out_ctr,
which was overwritten when writing the record containing the
HelloVerifyRequest starting from out_buf. We can avoid that by only using the
rest of the buffer.

Using MBEDTLS_SSL_MAX_CONTENT_LEN as the buffer size is still correct, as it
was a pretty conservative value when starting from out_buf.

Note: this bug was also fixed unknowingly in 2.13 by introducing a new buffer
that holds the current value of the sequence number (including epoch), while
working on datagram packing: 198594709b

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?).

Manuel Pégourié-Gonnard b1ee30bfe9 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.
