This test case was only executed if the SHA-512 module was enabled and
MBEDTLS_ENTROPY_FORCE_SHA256 was not enabled, so "config.pl full"
didn't have a chance to reach it even if that enabled
MBEDTLS_PLATFORM_NV_SEED_ALT.
Now all it takes to enable this test is MBEDTLS_PLATFORM_NV_SEED_ALT
and its requirements, and the near-ubiquitous MD module.
Call mbedtls_entropy_free on test failure.
Restore the previous NV seed functions which the call to
mbedtls_platform_set_nv_seed() changed. This didn't break anything,
but only because the NV seed functions used for these tests happened
to work for the tests that got executed later in the .data file.
memset has undefined behavior when either pointer can be NULL, which
is the case when it's the result of malloc/calloc with a size of 0.
The memset calls here are useless anyway since they come immediately
after calloc.
* origin/pr/2744:
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
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.
* origin/pr/2739:
Split _abi_compliance_command into smaller functions
Record the commits that were compared
Document how to build the typical argument for -s
Allow running /somewhere/else/path/to/abi_check.py
Record the commit ID in addition to the symbolic name of the version
being tested. This makes it easier to figure out what has been
compared when reading logs that don't always indicate explicitly what
things like HEAD are.
This makes the title of HTML reports somewhat verbose, but I think
that's a small price to pay.

If `make TEST_CPP:=1` is run, and then `make clean` (as opposed to `make
TEST_CPP:=1 clean`), the cpp_dummy_build will be left behind after the
clean. Make `make clean more convenient to use by removing programs that
could be generated from any configuration, not just the active one.
Fixes#1862
Inherit PlatformToolset from the project configuration. This allow the
project to configure PlatformToolset, and aligns the Release x64 build
with other build types.
Fixes#1430
With the change to the full config, there were no longer any tests
that exercise invalid-parameter behavior. The test suite exercises
invalid-parameter behavior by calling TEST_INVALID_PARAM and friends,
relying on the test suite's mbedtls_check_param function. This
function is only enabled if MBEDTLS_CHECK_PARAMS is defined but not
MBEDTLS_CHECK_PARAMS_ASSERT.
Add a component to all.sh that enables MBEDTLS_CHECK_PARAMS but
disables MBEDTLS_CHECK_PARAMS_ASSERT and doesn't define
MBEDTLS_PARAM_FAILED. This way, the xxx_invalid_param() tests do run.
Since sample programs don't provide a mbedtls_check_param function,
this component doesn't build the sample programs.
All sample and test programs had a definition of mbedtls_param_failed.
This was necessary because we wanted to be able to build them in a
configuration with MBEDTLS_CHECK_PARAMS set but without a definition
of MBEDTLS_PARAM_FAILED. Now that we activate the sample definition of
MBEDTLS_PARAM_FAILED in config.h when testing with
MBEDTLS_CHECK_PARAMS set, this boilerplate code is no longer needed.
Introduce a new configuration option MBEDTLS_CHECK_PARAMS_ASSERT,
which is disabled by default. When this option is enabled,
MBEDTLS_PARAM_FAILED defaults to assert rather than to a call to
mbedtls_param_failed, and <assert.h> is included.
This fixes#2671 (no easy way to make MBEDTLS_PARAM_FAILED assert)
without breaking backward compatibility. With this change,
`config.pl full` runs tests with MBEDTLS_PARAM_FAILED set to assert,
so the tests will fail if a validation check fails, and programs don't
need to provide their own definition of mbedtls_param_failed().
Don't use the macro name assert. It's technically permitted as long as
<assert.h> is not included, but it's fragile, because it means the
code and any header that it includes must not include <assert.h>.
For unit tests and sample programs, CFLAGS=-m32 is enough to get a
32-bit build, because these programs are all compiled directly
from *.c to the executable in one shot. But with makefile rules that
first build object files and then link them, LDFLAGS=-m32 is also
needed.
If int is not capable of storing as many values as unsigned, the code
may generate a trap value. If signed int and unsigned int aren't
32-bit types, the code may calculate meaningless values.
The elements of the HAVEGE state are manipulated with bitwise
operations, with the expectations that the elements are 32-bit
unsigned integers (or larger). But they are declared as int, and so
the code has undefined behavior. Clang with Asan correctly points out
some shifts that reach the sign bit.
Use unsigned int internally. This is technically an aliasing violation
since we're accessing an array of `int` via a pointer to `unsigned
int`, but since we don't access the array directly inside the same
function, it's very unlikely to be compiled in an unintended manner.

To prevent dropping the same message over and over again, the UDP proxy
test application programs/test/udp_proxy _logically_ maintains a mapping
from records to the number of times the record has already been dropped,
and stops dropping once a configurable threshold (currently 2) is passed.
However, the actual implementation deviates from this logical view
in two crucial respects:
- To keep the implementation simple and independent of
implementations of suitable map interfaces, it only counts how
many times a record of a given _size_ has been dropped, and
stops dropping further records of that size once the configurable
threshold is passed. Of course, this is not fail-proof, but a
good enough approximation for the proxy, and it allows to use
an inefficient but simple array for the required map.
- The implementation mixes datagram lengths and record lengths:
When deciding whether it is allowed to drop a datagram, it
uses the total datagram size as a lookup index into the map
counting the number of times a package has been dropped. However,
when updating this map, the UDP proxy traverses the datagram
record by record, and updates the mapping at the level of record
lengths.
Apart from this inconsistency, the current implementation suffers
from a lack of bounds checking for the parsed length of incoming
DTLS records that can lead to a buffer overflow when facing
malformed records.
This commit removes the inconsistency in datagram vs. record length
and resolves the buffer overflow issue by not attempting any dissection
of datagrams into records, and instead only counting how often _datagrams_
of a particular size have been dropped.
There is only one practical situation where this makes a difference:
If datagram packing is used by default but disabled on retransmission
(which OpenSSL has been seen to do), it can happen that we drop a
datagram in its initial transmission, then also drop some of its records
when they retransmitted one-by-one afterwards, yet still keeping the
drop-counter at 1 instead of 2. However, even in this situation, we'll
correctly count the number of droppings from that point on and eventually
stop dropping, because the peer will not fall back to using packing
and hence use stable record lengths.
