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.
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.
This reverts commit 9b90f2e294.
Conflicts:
* tests/scripts/all.sh: do the same changes, dancing around the new
outcome file feature and components added in the same places.
Make sure that the components that are getting added back are at the
same locations as where they are now in mbedtls.
This reverts commit 1c66e48670.
Conflicts:
* include/mbedtls/check_config.h:
* MBEDTLS_SSL_PROTO_SSL3: there has been an addition (of
MBEDTLS_SHA512_NO_SHA384) at the place where it was removed. Re-add it
after (alphabetical order).
* MBEDTLS_ENABLE_WEAK_CIPHERSUITES: there has been an addition (of
MBEDTLS_CTR_DRBG_USE_128_BIT_KEY) at the place where it was removed.
Re-add it after (alphabetical order).

scripts/generate_features.pl.
* programs/test/query_config.c: re-generate by running

the reversed changes to config.py:
* Revert removing three symbols from the list of symbols to
exclude from full.
* Revert removing one symbol (MBEDTLS_NET_C) from the list of symbols
to exclude from baremetal.
* scripts/footprint.sh:
* Re-add the line to unset MBEDTLS_NET_C, but with config.py instead of
config.pl.
* tests/scripts/all.sh:
* component_test_no_platform: re-add the line to unset MBEDTLS_NET_C, but
with config.py instead of config.pl.
* component_build_arm_none_eabi_gcc,
component_build_arm_none_eabi_gcc_no_udbl_division,
component_build_arm_none_eabi_gcc_no_64bit_multiplication,
component_build_armcc: these components now use the baremetal
configuration, so they do not need to turn off MBEDTLS_NET_C explicitly.
The .pl version is now a compat wrapper around the .py script. Better call the
.py script directly.

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).
Goals:
* Build with common compilers with common options, so that we don't
miss a (potentially useful) warning only triggered with certain
build options.
* A previous commit removed -O0 test jobs, leaving only the one with
-m32. We have inline assembly that is disabled with -O0, falling
back to generic C code. This commit restores a test that runs the
generic C code on a 64-bit platform.
For each of the crypto-only presets, run the build and check that the
resulting libmbedx509 and libmbedtls are empty.
Don't bother testing, because for each crypto-only preset, another
component builds that plus the x509 and tls parts and tests
everything.
We already have a specific component in all.sh for testing SSLv3, we don't
need to also test it in components that aren't specifically about it.
Previously config.py full enabled SSLv3, but it no longer does since it is
deprecated.
When MBEDTLS_TEST_DEPRECATED is defined, run some additional tests to
validate deprecated PSA macros. We don't need to test deprecated
features extensively, but we should at least ensure that they don't
break the build.
Add some code to component_build_deprecated in all.sh to run these
tests with MBEDTLS_DEPRECATED_WARNING enabled. The tests are also
executed when MBEDTLS_DEPRECATED_WARNING and
MBEDTLS_DEPRECATED_REMOVED are both disabled.
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.
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.
First deal with deleted files.
* Files deleted by us: keep them deleted.
* Files deleted by them, whether modified by us or not: keep our version.

* `README.md`: conflict due to their change in a paragraph that doesn't exist in our version. Keep our version of this paragraph.
* `docs/architecture/Makefile`: near-identical additions. Adapt the definition of `all_markdown` and include the clean target.
* `doxygen/input/docs_mainpage.h`: conflict in the version number. Keep our version number.
* `include/mbedtls/config.h`: two delete/modify conflicts. Keep the removed chunks out.

* `library/error.c`: to be regenerated.
* `library/version_features.c`: to be regenerated.

Keep the following changes after examination:
* `.travis.yml`: all of their changes are relevant.
* `include/mbedtls/error.h`: do keep their changes. Even though Crypto doesn't use TLS errors, it must not encroach on TLS's allocated numbers.
* `tests/scripts/check-test-cases.py`: keep the code dealing with `ssl-opt.sh`. It works correctly when the file is not present.

Also:
* Change one comment in include/mbedtls/check_config.h.
* Change PERL to PYTHON in CMakeLists.txt.
MBEDTLS_PK_SIGNATURE_MAX_SIZE is tested in Mbed Crypto. Its effect on
Mbed TLS is also tested via the X.509 tests. The case of
MBEDTLS_MPI_MAX_SIZE < MBEDTLS_ECDSA_MAX_LEN, for which this component
was added as a regression test, is covered by config-suite-b.h which
is tested via test-ref-configs.pl.
Enabling memory_buffer_alloc is slow and makes ASan ineffective. We
have a patch pending to remove it from the full config. In the
meantime, disable it explicitly.
Some sanitizers default to displaying an error message and recovering.
This could result in a test being recorded as passing despite a
complaint from the sanitizer. Turn off sanitizer recovery to avoid
this risk.
