Now function mbedtls_ssl_set_hostname is compile-time configurable
in config.h with define MBEDTLS_X509_REMOVE_HOSTNAME_VERIFICATION.
This affects to many x509 API's. See config.h for details.
ssl_client2 and ssl_server2 either allow loading specific CRTs
and CAs from files, or to leave them unspecified, in which case
they're automatically picked from the test certificates.
The test certificates should be chosen in a way that when
not specifying any CRT or CA parameters, the automatically
chosen ones match - but if one of them is specified but not
the other, one should not expect tests to succeed.
With the recent switch to Secp256r1-based test certificates,
the default test certificates have changed, which breaks some
ssl-opt.sh tests which specify the server CRT explicitly but
not the client trusted CAs.
This commit fixes this by specifying the client's trusted CA
explicitly in accordance with the explicitly specified server CRT.
One test for running with MBEDTLS_ECDH_C on and one
for running MBEDTLS_ECDH_C off. Run ssl-opt.sh with Default, DTLS
and compatibility tests with TLS-ECDHE-ECDSA-WITH-AES-256-CBC-SHA.
tinyCrypt is still tested in the baremetal tests since it
is enabled in baremetal.h. Tests for minimal modifictions
of the default / full config enabling tinyCrypt will be
added elsewhere.
* mbedtls-2.16:
Fix parsing issue when int parameter is in base 16
Refactor receive_uint32()
Refactor get_byte function
Make the script portable to both pythons
Update the test encoding to support python3
update the test script
tests: Limit each log to 10 GiB
It happens regularly in test runs that the server example application
shuts down a connection, goes into waiting mode for a new connection,
and then receives the encrypted ClosureAlert from the client. The only
reason why this does currently not trigger the 'record from another epoch'
message is that we handle ClientHello parsing outside of the main record
stack because we want to be able to detect SSLv2 ClientHellos. However,
this is likely to go away, and once it happens, we'll see the log message.
Further, when record checking is used, every record, including the mentioned
closure alert, is passed to the record checking API before being passed to
the rest of the stack, which leads to the log message being printed.
In summary, grepping for 'record from another epoch' is a fragile way
of checking whether a reordered message has arrived. A more reliable
way is to grep for 'Buffer record from epoch' which is printed when
a record from a future epoch is actually buffered, and 'ssl_buffer_message'
which is the function buffering a future handshake message.
mbedtls_ssL_set_calc_verify_md() is used to select valid hashes when
writing the server's CertificateRequest message, as well as to verify
and act on the client's choice when reading its CertificateVerify
message.
If enabled at compile-time and configured via mbedtls_ssl_conf_sig_hashes()
the current code also offers SHA-1 in TLS 1.2. However, the SHA-1-based
handshake transcript in TLS 1.2 is different from the SHA-1 handshake
transcript used in TLS < 1.2, and we only maintain the latter
(through ssl_update_checksum_md5sha1()), but not the former.
Concretely, this will lead to CertificateVerify verification failure
if the client picks SHA-1 for the CertificateVerify message in a TLS 1.2
handshake.
This commit removes SHA-1 from the list of supported hashes in
the CertificateRequest message, and adapts two tests in ssl-opt.sh
which expect SHA-1 to be listed in the CertificateRequest message.
Fix error `ValueError: invalid literal for int() with base 10:` that
is caused when a parameter is given in base 16. Use relevant base
when calling `int()` function.
Call `greentea_getc()` 8 times, and then `unhexify` once, instead of
calling `receive_byte()`, which inside calls `greentea_getc()` twice,
for every hex digit.
Since Python3 handles encoding differently than Python2,
a change in the way the data is encoded and sent to the target is needed.
1. Change the test data to be sent as hex string
2. Convert the characters to binary bytes.
This is done because the mbed tools translate the encoding differently
(mbed-greentea, and mbed-htrunner)
Limit log output in compat.sh and ssl-opt.sh, in case of failures with
these scripts where they may output seemingly unlimited length error
logs.
Note that ulimit -f uses units of 512 bytes, so we use 10 * 1024 * 1024
* 2 to get 10 GiB.
