This commit adds four tests to tests/ssl-opt.sh:
(1) & (2): Check behaviour of optional/required verification when the
trusted CA chain is empty.
(3) & (4): Check behaviour of optional/required verification when the
client receives a server certificate with an unsupported curve.
The modular inversion function hangs when provided with the modulus
1. This commit refuses this modulus with a BAD_INPUT error code. It
also adds a test for this case.
The test case was generated by modifying our signature code so that it
produces a 7-byte long padding (which also means garbage at the end, so it is
essential to check that the error that is detected first is indeed the
padding rather than the final length check).
Fix a buffer overflow when writting a string representation of an MPI
number to a buffer in hexadecimal. The problem occurs because hex
digits are written in pairs and this is not accounted for in the
calculation of the required buffer size when the number of digits is
odd.
The first three test cases from test_suites_pkparse.data failed because
the key file they read requires DES to be read. However, POLARSSL_DES_C
was missing from the dependency list.
This curve has special arithmetic on 64 bit platforms and an untested
path lead to trying to free a buffer on the stack.
For the sake of completeness, a test case for a point with non-affine
coordinates has been added as well.
Fixes a regression introduced by an earlier commit that modified
x509_crt_verify_top() to ensure that valid certificates that are after past or
future valid in the chain are processed. However the change introduced a change
in behaviour that caused the verification flags MBEDTLS_X509_BADCERT_EXPIRED and
MBEDTLS_BADCERT_FUTURE to always be set whenever there is a failure in the
verification regardless of the cause.
The fix maintains both behaviours:
* Ensure that valid certificates after future and past are verified
* Ensure that the correct verification flags are set.
Modifies the function mbedtls_x509_crl_parse() to ensure that a CRL in PEM
format with trailing characters after the footer does not result in the
execution of an infinite loop.
The script, `tests/scripts/curves.pl` was broken, and did not build due to the
make command not having been updated with the change from polarssl to mbed TLS.
The tests load certificate chains from files. The CA chains contain a
past or future certificate and an invalid certificate. The test then
checks that the flags set are BADCERT_EXPIRED or BADCERT_FUTURE.
Various fixes to the all.sh script.
* support for two different versions of OpenSSL and GNUTLS, to allow testing of
legacy features, deprecated but not yet removed in the library.
* additional test builds for server only and client only builds
* removed error redirection on armcc to allow build errors to be output
* added tools checking, to ensure the absence of a tool will cause a failure, rather
than silently failing to execute a test
* added test for out of tree cmake builds
In a USENIX WOOT '16 paper the authors exploit implementation
mistakes that cause Initialisation Vectors (IV) to repeat. This
did not happen in mbed TLS, and this test makes sure that this
won't happen in the future either.
A new test option is introduced to ssl-opt.sh that checks the server
and client logs for a pattern and fails in case there are any
duplicates in the lines following the matching ones. (This is
necessary because of the structure of the logging)
Added a test case as well to utilise the new option. This test forces
the TLS-ECDHE-ECDSA-WITH-AES-256-GCM-SHA384 ciphersuite to make the
client and the server use an AEAD cipher.

The PKCS#1 standard says nothing about the relation between P and Q
but many libraries guarantee P>Q and mbed TLS did so too in earlier
versions.
This commit restores this behaviour.

This commit restores this behaviour.
The test suite was not properly backported and it remained unnoticed,
because it was not compile due to the change in the naming of the
compile time requirements.
The main goal with these tests is to test the bug in question and
they are not meant to test the entire PKCS#1 v1.5 behaviour. To
achieve full test coverage, further test cases are needed.
