6240defd17 Add MBEDTLS_TEST_CONSTANT_FLOW_MEMSAN
This option allows to test the constant-flow nature of selected code, using
MemSan and the fundamental observation behind ctgrind that the set of
operations allowed on undefined memory by dynamic analysers is the same as the
set of operations allowed on secret data to avoid leaking it to a local
attacker via side channels, namely, any operation except branching and
dereferencing.

(This isn't the full story, as on some CPUs some instructions have variable
execution depending on the inputs, most notably division and on some cores
multiplication. However, testing that no branch or memory access depends on
secret data is already a good start.)

66c3dc44f2 Include the library directory for the sake of 3rdparty
When compiling library files under `3rdparty/`, the directory containing
the `.c` file that is being compiled is not the current directory, so
headers from the `library/` directory are not found. Fix this by
adding `.` to the include path.

This was not detected until now because as of this commit, no 3rdparty
source file requires a header under `library/`.

Enable MBEDTLS_X509_ALLOW_EXTENSIONS_NON_V3 in the full config. There's

Add a missing dependency on !MBEDTLS_X509_ALLOW_EXTENSIONS_NON_V3 to

MBEDTLS_X509_ALLOW_EXTENSIONS_NON_V3 enabled.

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.

a9f64006ea Add support for const error description strings
Problem
-------
mbedtls_strerror is a utility function which converts an mbedTLS error code
into a human readable string. It requires the caller to allocate a buffer every
time an error code needs to be converted to a string. It is an overkill and a
waste of RAM for resource constrained microcontrollers - where the most common
use case is to use these strings for logging.

Solution
--------
The proposed commit adds two functions:

* const char * mbedtls_high_level_strerr( int error_code );
* const char * mbedtls_low_level_strerr( int error_code );

The above two functions convert the high level and low level parts of an mbedTLS
error code to human readable strings. They return a const pointer to an
unmodifiable string which is not supposed to be modified by the caller and only
to be used for logging purposes. The caller no longer needs to allocate a
buffer.

Backward Compatibility
----------------------
The proposed change is completely backward compatible as it does not change
the existing mbedtls_strerror function and ensures that it continues to behave
the same way.

6e97c43959 Switch to the classic Mbed TLS ChangeLog format
Instead of working with Markdown format, keep the classic Mbed TLS
ChangeLog format, with the classic category names. Keep the classic
file name as well. This way there's no risk of breaking third-party
scripts that may copy or even parse the changelog file.

Accordingly, expect ChangeLog/*.txt files instead of ChangeLog/*.md.

This commit completely rewrites the parsing and output code.

Don't use a function argument as a for loop variable. It worked (mostly) but

eccd888717 Rename identifiers containing double-underscore
Rename identifiers containing double-underscore (`__`) to avoid `__`.
The reason to avoid double-underscore is that all identifiers
containing double-underscore are reserved in C++. Rename all such
identifiers that appear in any public header, including ssl_internal.h
which is in principle private but in practice is installed with the
public headers.

This commit makes check-names.sh pass.

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.

9693ea2490 Fix output_env.sh for varying pylint3 output
`pylint3 --version` will output to stderr the status of the config file it's
using. This can be "No config file found" or "Using config file" or nothing.
This means the pylint version may or may not be on the first line.

Therefore this commit changes the filters on the pylint3 version output to first
strip out the config line, and then to select only the pylint line.

7156d8cda9 Don't hard-code include paths in templates
generate_visualc_files.pl has a list of directories that it pulls
headers from, so it knows what directories to put on the include path.
Make it inject the include path into the output files, rather than
hard-coding the include paths in template files.

A similar change (but with different code) was made in Mbed TLS in

Minor rework of how files are removed. Actually do remove the

commented out).

df587ee6d6 Remove duplicate include statement
Now that the Error module has error codes as well and is processed by
the generate_errors script like any other module, we don't need to
include the header manually.

2d20567122 Add two error codes to the Error module
One of the error codes was already reserved, this commit just makes it
explicit. The other one is a new error code for initializing return
values in the library: `MBEDTLS_ERR_ERROR_CORRUPTION_DETECTED` should
not be returned by the library. If it is returned, then it is surely a
bug in the library or somebody is tampering with the device.

49af2d3a4f Support non-ASCII characters in headers
Filter out non-ASCII characters in automatically processed headers.

Do this in a way that minimizes the code change: keep manipulating
strings, but strip off non-ASCII characters when reading lines, which
should only remove characters in comments that we don't parse anyway.

80a607171a config.pl full: exclude MBEDTLS_ENTROPY_FORCE_SHA256
This is a variant toggle, not an extra feature, so it should be tested
separately.

We test most of the effect of MBEDTLS_ENTROPY_FORCE_SHA256 (namely,
using SHA-256 in the entropy module) when we test the library with the
SHA512 module disabled (which we do at least via depends-hashes.pl).
This commit removes testing of the MBEDTLS_ENTROPY_FORCE_SHA256 option
itself, which should be added separately.

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.

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.

812f185bc8 Also search config.h near the script
By default, this script looks for include/mbedtls/config.h relative to
the current directory. This allows running config.py from outside the
build tree.

To support out-of-tree builds where config.h and config.py are in the
source tree and the current directory is in the build tree, also try
DIRECTORY_CONTAINING_SCRIPT/../include/mbedtls/config.h, and the
equivalent with symbolic links traversed.

40b3f411ec Changelog merging script
assemble_changelog.py reads changelog entries from ChangeLog.d/*.md
and merges them into ChangeLog.md.

The changelog entries are merged into the first version in
ChangeLog.md. The script does not yet support creating a new version
in ChangeLog.md.

The changelog entries are merged in alphabetical order of the file
names. Future versions of this script are likely to adopt a different
order that reflects the git history of the entries.
