The uint32 is given as a bigendian stream, in the tests, however,
the char buffer that collected the stream read it as is,
without converting it. Add a temporary buffer, to call `greentea_getc()`
8 times, and then put it in the correct endianity for input to `unhexify()`.
Reduce the stack usage of the `test_suite_pkcs1_v21` by reducing the
size of the buffers used in the tests, to a reasonable big enough size,
and change the size sent to the API to sizeof output.
Reduce the stack usage of the `test_suite_rsa` by reducing the
size of the buffers used in the tests, to a reasonable big enough size,
and change the data size to decrypt in the data file.

In TLS, the master secret is always a key. But EAP-TLS uses the TLS
PRF to derive an IV with an empty string for the "secret" input. The
code always stored the secret into a key slot before calling the TLS
PRF, but this doesn't work when the secret is empty, since PSA Crypto
no longer supports empty keys. Add a special case for an empty secret.
Add a very basic test of calloc to the selftest program. The selftest
program acts in its capacity as a platform compatibility checker rather
than in its capacity as a test of the library.
The main objective is to report whether calloc returns NULL for a size
of 0. Also observe whether a free/alloc sequence returns the address
that was just freed and whether a size overflow is properly detected.
The current test generator code accepts multiple colons as a
separator, but this is just happenstance due to how the code, it isn't
robust. Replace "::" by ":", which is more future-proof and allows
simple separator-based navigation.
Make check-test-cases.py pass.
Prior to this commit, there were many repeated test descriptions, but
none with the same test data and dependencies and comments, as checked
with the following command:
for x in tests/suites/*.data; do perl -00 -ne 'warn "$ARGV: $. = $seen{$_}\n" if $seen{$_}; $seen{$_}=$.' $x; done
Wherever a test suite contains multiple test cases with the exact same
description, add " [#1]", " [#2]", etc. to make the descriptions
unique. We don't currently use this particular arrangement of
punctuation, so all occurrences of " [#" were added by this script.
I used the following ad hoc code:
import sys
def fix_test_suite(data_file_name):
in_paragraph = False
total = {}
index = {}
lines = None
with open(data_file_name) as data_file:
lines = list(data_file.readlines())
for line in lines:
if line == '\n':
in_paragraph = False
continue
if line.startswith('#'):
continue
if not in_paragraph:
# This is a test case description line.
total[line] = total.get(line, 0) + 1
index[line] = 0
in_paragraph = True
with open(data_file_name, 'w') as data_file:
for line in lines:
if line in total and total[line] > 1:
index[line] += 1
line = '%s [#%d]\n' % (line[:-1], index[line])
data_file.write(line)
for data_file_name in sys.argv[1:]:
fix_test_suite(data_file_name)
A test case for 32+0 was present three times, evidently overeager
copy-paste. Replace the duplicates by test cases that read more than
32 bytes, which exercises HKDF a little more (32 bytes is significant
because HKDF-SHA-256 produces output in blocks of 32 bytes).
I obtained the test data by running our implementation, because we're
confident in our implementation now thanks to other test cases: this
data is useful as a non-regression test.
There should have been a good-saltlen test case and a bad-saltlen test
case for both sizes 522 and 528, but the 522-bad-saltlen test case was
missing and the 528-good-saltlen test case was repeated. Fix this.
Don't use semicolons in test case descriptions. The test outcome file
is a semicolon-separated CSV file without quotes to keep things
simple, so fields in that file may not contain semicolons.
The tests were not covering get for a symbol with a value. No symbol
has an uncommented value in the default config.h. (Actually there's
_CRT_SECURE_NO_DEPRECATE, but that's a bit of a hack that this script
is not expected to handle, so don't use it).
Add tests of "get FOO" after "set FOO" and "set FOO value", so that we
have coverage for "get FOO" when "FOO" has a value.
We currently test setting a symbol with a value even if it didn't
originally had one and vice versa. So there's no need to have separate
lists of symbols to test with. Just test everything we want to test
with each symbol.
Set MBEDTLS_TEST_PLATFORM and MBEDTLS_TEST_CONFIGURATION to meaningful
values in all.sh. These environment variables are used when
writing an outcome file, which happens if MBEDTLS_TEST_OUTCOME_FILE is
also set.
When running one of the try-multiple-configuration scripts, set
MBEDTLS_TEST_CONFIGURATION to a value that uniquely describes the
configuration.
Don't use semicolons in test case descriptions. The test outcome file
is a semicolon-separated CSV file without quotes to keep things
simple, so fields in that file may not contain semicolons.
If the environment variable MBEDTLS_TEST_OUTCOME_FILE is set, then for
each test case, write a line to the file with the given name, of the
form
PLATFORM;CONFIGURATION;ssl-opt;TEST CASE DESCRIPTION;PASS/FAIL/SKIP;CAUSE
PLATFORM and CONFIGURATION come from the environment variables
MBEDTLS_TEST_PLATFORM and MBEDTLS_TEST_CONFIGURATION. If these
variables are unset, the script uses some easily-calculated values.
If the environment variable MBEDTLS_TEST_OUTCOME_FILE is set, then for
each test case, write a line to the file with the given name, of the
form
PLATFORM;CONFIGURATION;TEST SUITE;TEST CASE DESCRIPTION;PASS/FAIL/SKIP;CAUSE
PLATFORM and CONFIGURATION come from the environment variables
MBEDTLS_TEST_PLATFORM and MBEDTLS_TEST_CONFIGURATION.
Errors while writing the test outcome file are not considered fatal,
and are not reported except for an error initially opening the file.
This is in line with other write errors that are not checked.
This commit adds multiple test cases to the X.509 CRT parsing test suite
exercising the stack's behaviour when facing CertificatePolicy extensions
that are malformed for a variety of reasons. It follows the same scheme
as in other negative parsing tests: For each ASN.1 component, have test
cases for (a) unexpected tag, (b) missing length, (c) invalid length
encoding, (d) length out of bounds.
This commit modifies the test
X509 CRT ASN1 (TBSCertificate v3, inv CertificatePolicies, data missing)
which exercises the behaviour of the X.509 CRT parser when facing a
CertificatePolicy extension with empty data field.
The following adaptations are made:
- The subject ID and issuer ID are modified to have length 0.
The previous values `aa` and `bb` are OK, but a generic ASN.1
parser will try to interpret them as ASN.1 tags and fail. For
maintainability, it's therefore better to use something that
can be parsed as ASN.1, and an empty ID is the easiest solution
here.
- The TBS part of the certificate wasn't followed by signature
algorithm and signature fields, which makes the test incompatible
with future changes swapping to breadth-first parsing of
certificates.
This commit moves the X.509 negative parsing tests for the
CertificatePolicy extension to the place where negative
testing of other extensions happens.
Judging from its name, the purpose of the test
TBSCertificate v3, ext CertificatePolicies tag, bool len missing
in test_suite_x509parse.data is to exercise the X.509 parsing stack's
behaviour when parsing a CertificatePolicy extension which lacks the
length field of the boolean 'Criticality' value.
However, the test fails at an earlier stage due to a mismatch of inner
and outer length of the explicit ASN.1 extensions structure.
Since we already have tests exercising
- mismatch of inner and outer length in the extensions structure, namely
'X509 CRT ASN1 (TBS, inv v3Ext, inner tag invalid)'
- missing length of the 'Criticality' field in an extension, namely
'X509 CRT ASN1 (TBS, inv v3Ext, critical length missing)'
and since for both tests there's no relevance to the use of the
policy extension OID, the test
'TBSCertificate v3, ext CertificatePolicies tag, bool len missing'
can be dropped.
