3e2ee3cedc Check only files checked into Git
We're only interested in files that are committed and pushed to be
included in Mbed TLS, not in any other files that may be lying around.
So ask git for the list of file names.

This script is primarily intended to run on the CI, and there it runs
on a fresh Git checkout plus potentially some other checkouts or
leftovers from a previous part of the CI job. It should also run
reasonably well on developer machines, where there may be various
additional files. In both cases, git is available.

Ad hoc directory exclusions are no longer needed.

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

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). Look for `ssl-opt.sh` and `compat.sh`, as well any file in `tests/scripts` that only exists in tls.

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.
