1093d9f9af all.sh: reorganize testing around deprecated features
build_deprecated combined the testing of deprecated features, and
testing of the build without deprecated features. Also, it violated the
component naming convention by being called build_xxx but running tests.

Replace it by:
* test_default_no_deprecated: check that you can remove deprecated
  features from the default build.
* test_full_no_deprecated: check that the library builds when deprecated
  features are disabled (and incidentally that the tests run).
* test_no_deprecated_warning: check that there are no warnings when
  deprecated features are disabled and MBEDTLS_DEPRECATED_WARNING
  is enabled.
* test_deprecated: test the deprecated features.

32e889dfc3 Document and fix the MBEDTLS_xxx_ALT logic for the full config
The intended logic around MBEDTLS_xxx_ALT is to exclude them from full
because they require the alternative implementation of one or more
library functions, except that MBEDTLS_PLATFORM_xxx_ALT are different:
they're alternative implementations of a platform function and they
have a built-in default, so they should be included in full. Document
this.

Fix a bug whereby MBEDTLS_PLATFORM_xxx_ALT didn't catch symbols where
xxx contains an underscore. As a consequence,
MBEDTLS_PLATFORM_GMTIME_R_ALT and MBEDTLS_PLATFORM_NV_SEED_ALT are now
enabled in the full config. Explicitly exclude
MBEDTLS_PLATFORM_SETUP_TEARDOWN_ALT because it behaves like the
non-platform ones, requiring an extra build-time dependency.
Explicitly exclude MBEDTLS_PLATFORM_NV_SEED_ALT from baremetal
because it requires MBEDTLS_ENTROPY_NV_SEED, and likewise explicitly
unset it from builds that unset MBEDTLS_ENTROPY_NV_SEED.

bfcb6e16ab Create a large enough seedfile
The seedfile needs to have the size of the entropy accumulator, which
is 64 bytes (512 bits) since the entropy accumulator uses SHA-512 and
the seed size needs to be the same as the hash output (or larger).

We used to enable MBEDTLS_ENTROPY_FORCE_SHA256 in the full config, so
the entropy accumulator was 256 bits (32 bytes), and therefore a
32-byte seedfile worked. But we no longer turn on this option in the
full config, so the 32-byte seedfile no longer works.

56e99d623d Make sure to use a Python 3 pylint
On some systems, such as Ubuntu up to 19.04, `pylint` is for Python 2
and `pylint3` is for Python 3, so we should not use `pylint` even if
it's available.

Use the Python module instead of the trivial shell wrapper. This way
we can make sure to use the correct Python version.

Look for any other invocation of test scripts that was removed: look for a change that removes a line (`^-.*…`) containing one of the names of a test script (without its path because it may be used with a relative path).

636c26ad75 Restore full tls coverage to all.sh
The merge of mbed-crypto removed some tls coverage. Restore it. Also
remove references to the `crypto` subdirectory brought by the mbedtls
side of the merge. In more detail:

* `tests/scripts/all.sh`:
    * `fuzz` in comments (×2): restore it.
    * `CTEST_OUTPUT_ON_FAILURE=1`: don't remove it.
    * `cd crypto` for `make clean`: don't restore it.
    * `cleanup`: do restore `programs/fuzz/Makefile`. Don't go into `crypto`. Keep only one copy of the calls to `rm` in `cmake_subproject`.
    * Comment legacy options: don't remove it.
    * `crypto/Makefile` and `pre_check_seedfile`: don't restore either. See below regarding the lack of need for `pre_check_seedfile`.
    * blank line in `pre_print_configuration`: restore it.
    * blank line before `#### Build and test`: restore it.
    * SSL tests in `component_test_full_cmake_gcc_asan` and zlib components: restore it.
    * `component_test_no_pem_no_fs` (×2): the merge placed two copies in different locations. Reconcile them: unset PSA storage like in crypto, and call `ssl-opt.sh` like in tls. Put the merged version at the tls location.
    * `component_test_everest`: do add it at the tls location.
    * `component_test_small_mbedtls_ssl_dtls_max_buffering`: restore the tls value.
    * `component_test_new_ecdh_context`…: move `component_test_new_ecdh_context` before `component_test_everest` and add a calls to `compat.sh` and `ssl-opt.sh` like in `component_test_everest`. Remove the redundant crypto-only `component_test_everest`. Don't remove `component_test_psa_collect_statuses`.
    * `component_test_full_cmake_clang`: don't remove `clang` in the `msg` call. Don't remove the call to `test_psa_constant_names.py`.
    * `component_test_full_make_gcc_o0`: remove it. It's subsumed by `component_test_gcc_opt`.
    * `component_build_deprecated`: don't remove anything.
    * `component_test_memory_buffer_allocator`: restore `ssl-opt.sh`.
    * `component_test_when_no_ciphersuites_have_mac`: restore it.
    * `component_test_platform_calloc_macro`: don't restore `unset MBEDTLS_MEMORY_BUFFER_ALLOC_C` which is now redundant. Don't restore explicit flags instead of `$ASAN_CFLAGS`.
    * `component_test_aes_fewer_tables`…: don't remove it.
    * `component_test_m32_o1`: restore SSL testing.
    * `component_test_m32_everest`: restore SSL testing.
    * `component_test_min_mpi_window_size`…: don't remove it.
    * `component_test_valgrind`: do restore the tls version of the comment.
    * `run_component`: don't remove the seedfile creation. This is better than `pre_check_seedfile` (see below).
    * `pre_check_seedfile`: don't restore it. `pre_check_seedfile` (from tls) creates a seedfile once and for all. This is not good enough if a component fails in such a way as to leave a broken seedfile, or if a component leaves a seedfile with a size that's wrong for the next component to run. Instead (from crypto), `run_component` creates a sufficiently large seedfile before each component.

b99bd39b4e Merge mbed-crypto into mbedtls: the merge commit
Merge `unremove-non-crypto` into `mbedtls/development`. The branch
`unremove-non-crypto` was obtained by starting from `mbed-crypto/development`,
then reverting many commits that removed X.509 and TLS functionality when Mbed
Crypto forked from Mbed TLS (the “unremoval”), then make a few tweaks to
facilitate the merge.

The unremoval step restored old versions of some tls files. If a file doesn't
exist in mbed-crypto, check out the mbedtls version, regardless of what
happened during the unremoval of tls files in the crypto tree. Also
unconditionally take the mbedtls version of a few files where the
modifications are completely project-specific and are not relevant in
mbed-crypto:

* `.github/issue_template.md`: completely different. We may want to reconcile
  them independently as a follow-up.
* `.travis.yml`: would only be reverted to an earlier tls version.
* `README.md`: completely different. We may want to reconcile them
  independently as a follow-up.
* `doxygen/input/doc_mainpage.h`: the changes in crypto were minimal and not
  relevant except as a stopgap as mbed-crypto did not have its own product
  versioning in the Doxygen documentation.
* `tests/.jenkins/Jenkinsfile`: completely different.
* `tests/data_files/Makefile`: there were no changes in mbed-crypto,
  but the unremoval step restored an old version.

Shell script for everything to do after the merge apart from the conflict
resolution:
```
tls_files=($(comm -23 <(git ls-tree -r --name-only HEAD) <(git ls-tree -r --name-only $(git merge-base upstream-crypto/development MERGE_HEAD))))
tls_files+=($tls_files .github/issue_template.md .travis.yml README.md doxygen/input/doc_mainpage.h tests/.jenkins/Jenkinsfile tests/data_files/Makefile)
git checkout --theirs HEAD -- $tls_files
git add -- $tls_files
```

Resolve the remaining conflicts:

* `library/CMakeLists.txt`:
    * Keep the TLS definition of `src_crypto`
    * `USE_SHARED_MBEDTLS_LIBRARY`: keep all three libraries, with both
      `include` and `crypto/include` in `target_include_directories`, all with
      version `2.21.0`.
* `programs/Makefile`:
    * Reconcile the APPS lists (add/add from a differently-formatted common
      ancestor): insert the `psa/*` from crypto into the tls list.
    * Keep the `fuzz` target defined only in tls version.
    * Keep the recipe (only in tls version) cleaning `ssl_pthread_server`
      stuff for the `clean` target.
* `scripts/config.py`:
    * `include_in_full`: add/add conflict. Keep both.
* `tests/scripts/all.sh`:
    * `component_test_no_use_psa_crypto_full_cmake_asan`: partially old
      version in crypto. Take the tls version.
    * `component_test_malloc_0_null` and more: take
      `component_test_malloc_0_null` from crypto (with `config.py` rather than
      `config.pl`, and with `$ASAN_FLAGS` rather than an explicit list), but
      add the call to `ssl-opt.sh` from tls. Take the other components from
      crypto.

With this commit, building and running the unit tests with both `make ` and
`cmake` work in the default configuration on Linux. Other platforms, build
systems and configurations are likely not to work, and there is some
regression in test coverage.

There is some loss of functionality because the unremoval step restored older
versions of tls content. This commit contains the latest tls version of
tls-only files, but some changes from the tls side in files that existed on
both sides have regressed. Most problematic changes are hunks that remove some
tls-specific feature and contain either a C preprocessor symbol identifying a
tls-specific module or option, or the name of a tls-specific file. Hunks
that remove a tls-specific preprocessor symbol can be identified with the
regular expression `^-.*MBEDTLS_(ERR_)?(PKCS11|X509|NET|SSL)_`.

Subsequent commits will revert a few parts of the patch from this merge commit
in order to restore the tls functionality that it removes, ensure that the
test coverage includes what was covered in either branch, and fix test
failures.

e30d03e4f4 Change the use of pylint to optionally use pylint3
Pylint when installed as a distro package can be installed as pylint3, whilst as
a PEP egg, it can be installed as pylint.

This commit changes the scripts to first use pylint if installed, and optionally
look for pylint3 if not installed. This is to allow a preference for the PEP
version over the distro version, assuming the PEP one is more likely to be
the correct one.

765d240ca6 Test component with malloc(0) returning NULL: run some ssl tests 2020-02-11 19:26:28 +01:00
Gilles Peskine
c4ef7a9de3 Add a test component with malloc(0) returning NULL
Exercise the library functions with calloc returning NULL for a size
of 0. Make this a separate job with UBSan (and ASan) to detect
places where we try to dereference the result of calloc(0) or to do
things like

    buf = calloc(size, 1);
    if (buf == NULL && size != 0) return INSUFFICIENT_MEMORY;
    memcpy(buf, source, size);

which has undefined behavior when buf is NULL at the memcpy call even
if size is 0.

This is needed because other test components jobs either use the system
malloc which returns non-NULL on Linux and FreeBSD, or the
memory_buffer_alloc malloc which returns NULL but does not give as
useful feedback with ASan (because the whole heap is a single C
object).

7cb47de12a query_config: Move to programs/test
As the SSL programs, like ssl_client2 and ssl_server2, are dependent on

* A previous commit removed -O0 test jobs, leaving only the one with

f65ed6f254 Change key types to a 16-bit encoding
All key types now have an encoding on 32 bits where the bottom 16 bits
are zero. Change to using 16 bits only.

Keep 32 bits for key types in storage, but move the significant
half-word from the top to the bottom.

Likewise, change EC curve and DH group families from 32 bits out of
which the top 8 and bottom 16 bits are zero, to 8 bits only.

tests.

Switch the slot management and secure element driver HAL tests to the
new curve encodings. This requires SE driver code to become slightly
more clever when figuring out the bit-size of an imported EC key since
it now needs to take the data size into account.

Switch some documentation to the new encodings.

7a894f2142 Move backward compatibility aliases to their own header
Move backward compatibility aliases to a separate header. Reserve
crypto_extra.h for implementation-specific extensions that we intend

This is better documentation for users. New users should simply ignore
backward compatibility aliases, and old users can look at
crypto_compat.h to see what is deprecated without bothering about new
features appearing in crypto_extra.h.

This facilitates maintenance because scripts such as
generate_psa_constants that want to ignore backward compability
aliases can simply exclude crypto_compat.h from their parsing.

2ef377d56d all.sh: support variable seedfile size
The size of the seedfile used by the entropy module when
MBEDTLS_ENTROPY_NV_SEED is enabled is 32 byte when
MBEDTLS_ENTROPY_FORCE_SHA256 is enabled or MBEDTLS_SHA512_C is
disabled, and 64 bytes otherwise. A larger seedfile is ok on
entry (the code just grabs the first N bytes), but a smaller seedfile
is not ok. Therefore, if you run a component with a 32-byte seedfile
and then a component with a 64-byte seedfile, the second component
fails in the unit tests (up to test_suite_entropy which erases the
seedfile and creates a fresh one).

This is ok up to now because we only enable MBEDTLS_ENTROPY_NV_SEED
together with MBEDTLS_ENTROPY_FORCE_SHA256. But it prevents enabling
MBEDTLS_ENTROPY_NV_SEED without MBEDTLS_ENTROPY_FORCE_SHA256.

To fix this, unconditionally create a seedfile before each component.

24600e8290 Disable memory_buffer_alloc in the full config
Enabling MBEDTLS_MEMORY_BUFFER_ALLOC_C module together with
MBEDTLS_PLATFORM_MEMORY causes the library to use its own malloc
replacement. This makes memory management analyzers such as ASan
largely ineffective. We now test MBEDTLS_MEMORY_BUFFER_ALLOC_C
separately. Disable it in the "full" config.

This mirrors a change that was made in Mbed TLS on config.pl and had
not been ported to Mbed Crypto yet.

With this commit, config.py is aligned in Mbed Crypto and Mbed TLS.

adc82f3535 Add set+get tests
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).

261742bd59 Fix config.py output when a symbol has acquired or lost a value
Normally a valueless symbol remains valueless and a symbol with a
value keeps having one. But just in case a symbol does get changed
from valueless to having a value, make sure there's a space between
the symbol and the value. And if a symbol gets changed from having a
value to valueless, strip trailing whitespace.

Add corresponding tests.

Also fix the case of a valueless symbol added with the set method,
which would have resulted in attempting to use None as a string. This
only happened with the Python API, not with the command line API.

aebf0027c0 Test script for config.py
Run config.py with various options and store the results in files.

This script also supports the now-removed config.pl.

This is a framework to run non-regression tests on config.py: run it
with the old version, run it with the new version, and compare the
output.

This is deliberately not a functional test suite so that we don't need
to maintain a set of known outputs. When something changes in
config.py (or config.h), run the script before, run it after, and
check manually whether any differences in the output are acceptable.

Mbed TLS is also tested via the X.509 tests. The case of

was added as a regression test, is covered by config-suite-b.h which

ce35cb3cc7 'make test' must fail if Asan fails
When running 'make test' with GNU make, if a test suite program
displays "PASSED", this was automatically counted as a pass. This
would in particular count as passing:
* A test suite with the substring "PASSED" in a test description.
* A test suite where all the test cases succeeded, but the final
  cleanup failed, in particular if a sanitizer reported a memory leak.

Use the test executable's return status instead to determine whether
the test suite passed. It's always 0 on PASSED unless the executable's
cleanup code fails, and it's never 0 on any failure.

31b0a3c351 Add a test component with malloc(0) returning NULL
Exercise the library functions with calloc returning NULL for a size
of 0. Make this a separate job with UBSan (and ASan) to detect
places where we try to dereference the result of calloc(0) or to do
things like

    buf = calloc(size, 1);
    if (buf == NULL && size != 0) return INSUFFICIENT_MEMORY;
    memcpy(buf, source, size);

which has undefined behavior when buf is NULL at the memcpy call even
if size is 0.

This is needed because other test components jobs either use the system
malloc which returns non-NULL on Linux and FreeBSD, or the
memory_buffer_alloc malloc which returns NULL but does not give as
useful feedback with ASan (because the whole heap is a single C
object).

eef4c753f1 Adapt buffering test to new ticket size
The size of the ticket used in this test dropped from 192 to 143 bytes, so
move all sizes used in this test down 50 bytes. Also, we now need to adapt the
server response size as the default size would otherwise collide with the new
mtu value.

72c8c5b352 Merge remote-tracking branch 'upstream-crypto/development' into psa-api-1.0-beta-merge_development_20190801
Conflict resolution:
* `scripts/config.pl`:
  Take the exclusion of `MBEDTLS_PSA_CRYPTO_SE_C` from the API branch.
  Take the removal of `MBEDTLS_PSA_CRYPTO_STORAGE_ITS_C` (obsolete) from
  the development branch.
* `tests/scripts/all.sh`:
  Multiple instances of factoring a sequence of `config.pl` calls into
  a mere `config.pl baremetal` in the development branch, and a change in
  the composition of `baremetal` in the API branch. In each case, take the
  version from development.
* `tests/suites/test_suite_psa_crypto_slot_management.function`:
  A function became non-static in development and disappeared in the API
  branch. Keep the version from the API branch. Functions need to be
  non-static if they're defined but unused in some configurations,
  which is not the case for any function in this file at the moment.
* `tests/suites/test_suite_psa_crypto.function`:
  Consecutive changes in the two branches, reconciled.

8dd1690993 Merge remote-tracking branch 'tls/development' into development
Resolve conflicts by performing the following operations:
- Reject changes related to building a crypto submodule, since Mbed
  Crypto is the crypto submodule.
- Reject X.509, NET, and SSL changes.
- Reject changes to README, as Mbed Crypto is a different project from
  Mbed TLS, with a different README.
- Avoid adding mention of ssl-opt.sh in a comment near some modified
  code in include/CMakeLists.txt (around where ENABLE_TESTING as added).
- Align config.pl in Mbed TLS with config.pl in Mbed Crypto where PSA
  options are concerned, to make future merging easier. There is no
  reason for the two to be different in this regard, now that Mbed TLS
  always depends on Mbed Crypto. Remaining differences are only the
  PSA_CRYPTO_KEY_FILE_ID_ENCODES_OWNER option and the absence of X.509,
  NET, and SSL related options in Mbed Crypto's config.pl.
- Align config.h in Mbed Crypto with Mbed TLS's copy, with a few notable
  exceptions:
  - Leave CMAC on by default.
  - Leave storage on by default (including ITS emulation).
  - Avoid documenting the PSA Crypto API as is in beta stage in
    documentation for MBEDTLS_PSA_CRYPTO_C.
  The only remaining differences are a lack of X.509, NET, and SSL
  options in Mbed Crypto's config.h, as well as an additional
  Mbed-Crypto-specific PSA_CRYPTO_KEY_FILE_ID_ENCODES_OWNER option.
  Documentation for the check params feature and related macros is also
  updated to match Mbed TLS's description.
- Reject tests/data_files/Makefile changes to generate DER versions of
  CRTs and keys, as none of those are used by Mbed Crypto tests.
- Add the "no PEM and no filesystem" test to all.sh, without ssl-opt.sh
  run, as Mbed Crypto doesn't have ssl-opt.sh. Also remove use of PSA
  Crypto storage and ITS emulation, since those depend on filesystem
  support.
- Reject addition of test when no ciphersuites have MAC to all.sh, as
  the option being tested, MBEDTLS_SSL_SOME_MODES_USE_MAC, is not
  present in Mbed Crypto.
- Use baremetal config in all.sh, as Mbed Crypto's baremetal
  configuration does exclude the net module (as it doesn't exist in Mbed
  Crypto)
- Reject cmake_subproject_build changes, continuing to link only
  libmbedcrypto.
- Reject changes to visualc and associated templates. Mbed Crypto
  doesn't need additional logic to handle submodule-sourced headers.
- Avoid adding fuzzers from Mbed TLS. The only relevant fuzzers are the
  privkey and pubkey fuzzers, but non-trivial work would be required to
  integrate those into Mbed Crypto (more than is comfortable in a merge
  commit).
- Reject addition of Docker wrappers for compat.sh and ssl-opt.sh, as
  those are not present in Mbed Crypto.
- Remove calls to SSL-related scripts from basic-in-docker.sh

Fix test errors by performing the following:
- Avoid using a link that Doxygen can't seem to resolve in Mbed Crypto,
  but can resolve in Mbed TLS. In documentation for
  MBEDTLS_CHECK_PARAMS, don't attempt to link to MBEDTLS_PARAM_FAILED.

5075f4df18 Update the test encoding to support python3
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

adcde5e997 Add all.sh component that exercises invalid_param checks
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.

c1955559ad Add a test for signing content with a long ECDSA key
Due to the way the current PK API works, it may have not been clear
for the library clients, how big output buffers they should pass
to the signing functions. Depending on the key type they depend on
MPI or EC specific compile-time constants.

Inside the library, there were places, where it was assumed that
the MPI size will always be enough, even for ECDSA signatures.
However, for very small sizes of the MBEDTLS_MPI_MAX_SIZE and
sufficiently large key, the EC signature could exceed the MPI size
and cause a stack overflow.

This test establishes both conditions -- small MPI size and the use
of a long ECDSA key -- and attempts to sign an arbitrary file.
This can cause a stack overvlow if the signature buffers are not
big enough, therefore the test is performed for an ASan build.

5d26e7cbfe Pass -m32 to the linker as well
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.

6b1683dd5d all.sh: Perform targeted EtM tests for MAC-less configs
When testing a configuration where no ciphersuites have MAC, via
component_test_when_no_ciphersuites_have_mac(), perform a targeted test
of only encrypt-then-MAC tests within ssl-opt.sh.

2de07f1dd1 ssl: Don't access non-existent encrypt_then_mac field
When MBEDTLS_SSL_ENCRYPT_THEN_MAC is enabled, but not
MBEDTLS_SSL_SOME_MODES_USE_MAC, mbedtls_ssl_derive_keys() and
build_transforms() will attempt to use a non-existent `encrypt_then_mac`
field in the ssl_transform.

    Compile [ 93.7%]: ssl_tls.c
    [Error] ssl_tls.c@865,14: 'mbedtls_ssl_transform {aka struct mbedtls_ssl_transform}' ha
s no member named 'encrypt_then_mac'
    [ERROR] ./mbed-os/features/mbedtls/src/ssl_tls.c: In function 'mbedtls_ssl_derive_keys'
:
    ./mbed-os/features/mbedtls/src/ssl_tls.c:865:14: error: 'mbedtls_ssl_transform {aka str
uct mbedtls_ssl_transform}' has no member named 'encrypt_then_mac'
         transform->encrypt_then_mac = session->encrypt_then_mac;
                  ^~

Change mbedtls_ssl_derive_keys() and build_transforms() to only access
`encrypt_then_mac` if `encrypt_then_mac` is actually present.

Add a regression test to detect when we have regressions with
configurations that do not include any MAC ciphersuites.

Fixes d56ed2491b ("Reduce size of `ssl_transform` if no MAC ciphersuite is enabled")

3b025ac52b test: Always use make clean by itself
When running make with parallelization, running both "clean" and "lib"
with a single make invocation can lead to each target building in
parallel. It's bad if lib is partially done building something, and then
clean deletes what was built. This can lead to errors later on in the
lib target.

    $ make -j9 clean lib

To avoid this sort of trouble, always invoke clean by itself without
other targets throughout the library. Don't run clean in parallel with
other rules. The only place where clean was run in parallel with other
targets was in list-symbols.sh.
