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.
git grep -Fl /config.pl | xargs sed -i -e 's!/config\.pl!/config.py!g'
Also:
* Change one comment in include/mbedtls/check_config.h.
* Change PERL to PYTHON in CMakeLists.txt.
They're easier to maintain that way. The old lists were partly
alphabetized, partly based on config.h order, and partly in the order
in which symbols had been added to config.pl.
Also fix 'realfull' to only affect the appropriate sections.
Tested to produce the same results as config.pl on the default
configuration. This commit deliberately contains a direct copy the
lists of symbol names from config.pl.
This is meant to be a drop-in replacement for config.pl which can
additionally be used as a library in a Python script.
So far this script supports the commands 'get', 'set' and 'realfull'
but not the other built-in configurations.
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.
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.

Conflicts and changes:
* Files that do not exist in Mbed Crypto and have changed in Mbed TLS:
These files should not exist in Mbed Crypto. Keep them deleted.
* tests/data_files/test-ca.server1.db: new file in Mbed TLS, don't create
it in Mbed Crypto.
* tests/data_files/rsa_pkcs1_1024_clear.pem: do create this file in
Mbed Crypto. I don't see why it would be kept out.
* tests/data_files/Makefile: don't take any of the changes in sections
that have been removed in Crypto. Do take in the certificate
expiration date updates and the extra .crt.der rules (even if Crypto
doesn't actually use those certificates: removing them would be out
of scope of the present merge).
* tests/suites/helpers.function: consecutive additions, take
both (order indifferent).
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.
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.

Due to how the checking script is run in docker, worktree_rev is
ambiguous when running rev-parse. We're running it in the checked
out worktree, so we can use HEAD instead, which is unambiguous.
Secure element support is not yet usable in the real world. Only part
of the feature is implemented and the part that's implemented is not
sufficient for real-world uses. A lot of error handling is missing,
and there are no tests.
This commit should be reverted once the feature has stabilized.
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.
Secure element support has its own source file, and in addition
requires many hooks in other files. This is a nontrivial amount of
code, so make it optional (but default on).

Previously it was disabled as too experimental, which no longer holds. Also,
this option introduces new APIs, so it's not only about an internal
alternative (as the comment in config.pl used to state) - people who request a
full config should get all of the available APIs.
Adapt all.sh: now all builds with full config will also test this option, and
builds with the default config will test without it. Just to be sure, let's
have a build with full config minus this option.
Update documentation of MBEDTLS_USE_PSA_CRYPTO to reflect the status of the
new APIs it enables in Mbed TLS and why they're still opt-in.
Also enable it in scripts/config.pl full, as well as two storage options that
were only blacklisted from full config because they depended on
MBEDTLS_PSA_CRYPTO_C.

Enabling the USE_CRYPTO_SUBMODULE option causes problems if the
crypto submodule isn't present. For example, when building
mbed-crypto as a submodule, it should use error.c from the parent
project if USE_CRYPTO_SUBMODULE is set. However if the parent
project isn't present, then the build will fail. Only enable it
if the submodule actually exists.

- Reject changes to deleted files.

Running the generation script with "include_crypto" input parameter set to 1
makes the mbedtls sources being overshadowed by crypto sources.
In case of any duplicate sources, crypto ones take precedence.
There are a number of arguments being passed around, nearly all of
which are duplicated between the old and new versions. Moving these
into a separate class should hopefully make it simpler to follow
what is being done.
As before with wanting to compare revisions across different
repositories, the ability to select the crypto submodule from a
different repository is useful.
We may wish to compare ABI/API between Mbed TLS and Mbed Crypto,
which will cause issues as not all .so files are shared. Only
compare .so files which both libraries have.
As going forward we will have Crypto in a submodule, we will need to
be able to check ABI compatibility between versions using different
submodule versions. For TLS versions that support the submodule, we
will always build using the submodule.
If the Crypto submodule is used, libmbedcrypto.so is not in the main
library folder, but in crypto/library instead. Given this, the script
searches for *.so files and notes their path, in order to create the
dumps correctly.
By default abi-compliance-checker will check the entire ABI/API.
There are internal identifiers that we do not promise compatibility
for, so we want the ability to skip them when checking the ABI/API.

Update the crypto submodule to the top of the Mbed Crypto development
branch. This brings in a version of Mbed Crypto that enables building
Mbed Crypto tests that depend on private headers, like
'psa_crypto_invasive.h'.
This also requires updating our config.h to include new configuration
options added to Mbed Crypto. MBEDTLS_PSA_ITS_FILE_C replaces
MBEDTLS_PSA_CRYPTO_STORAGE_FILE_C and MBEDTLS_PSA_CRYPTO_STORAGE_ITS_C.
MBEDTLS_PSA_INJECT_ENTROPY replaces MBEDTLS_PSA_HAS_ITS_IO.
MBEDTLS_PSA_HAS_ITS_IO is not really useful since it doesn't actually
enable anything except the entropy seed file support, which only
requires the ITS interface and not a native implemetation. Remove it.
Now that we have ITS over files, we no longer need a direct backend
for key storage over files. Remove psa_crypto_storage_file and its
tests.
Switch MBEDTLS_PSA_CRYPTO_STORAGE_ITS_C and MBEDTLS_PSA_ITS_FILE_C on
by default. This preserves functionality and test coverage in the
default configuration, but forgets any key previously stored using the
file backend.
As the SSL programs, like ssl_client2 and ssl_server2, are dependent on
SSL and therefore about to be removed, the only consumer of query_config
is the query_compile_time_config test. As such, it makes sense to move
query_config to be next to what uses it.

Resolve conflicts by performing the following.
- Take the upstream Mbed TLS ChangeLog verbatim.
- Reject changes to Makefiles and CMake that are related to using Mbed
Crypto as a submodule. It doesn't make sense to use Mbed Crypto as a
submodule of itself.
- Reject README changes, as Mbed Crypto has its own, different README.
- Reject PSA-related changes to config.h. We don't want to disable the
availability of the PSA Crypto API by default in the Mbed Crypto
config.h.
- Don't inadvertently revert dead code removal in
mbedtls_cipher_write_tag() which was added in f2a7529403 ("Fix
double return statement in cipher.c")
- Where Mbed Crypto already had some MBEDTLS_USE_PSA_CRYPTO code (from
past companion PRs) take the latest version from Mbed TLS which
includes integration with MBEDTLS_CHECK_PARAMS.
- Update the version of the shared library files to match what's
currently present in Mbed TLS.
- Reject removal of testing with PSA from config full tests.
- Resolve conflicts in test tests/suites/helpers.function, where both
Mbed Crypto and Mbed TLS both added documentation for TEST_ASSERT.
Combine text from both documentation efforts.
- Reject adding a submodule of ourselves.
- Reject addition of submodule tests in all.sh.
- Reject addition of submodule to library path in

- Avoid using USE_CRYPTO_SUBMODULE=1 in

test_psa_constant_names.py was originally written before the split of
crypto.h into crypto_values.h and more, so it now needs to read
crypto_values.h as well.
In both generate_psa_constants.py and test_psa_constant_names.py, read
crypto_extra.h as well. We don't currently define any value there, but
it's plausible that we will one day.
Some parts of the library, and crypto drivers, need to see key types,
algorithms, policies, etc. but not API functions. Move portable
integral types and macros to build and analyze values of these types
to a separate headers crypto_types.h and crypto_values.h.
No functional changes, code was only moved from crypto.h to the new headers.
Without a "--detach" option, git worktree will refuse to checkout a branch
that's already checked out. This makes the abi_check.py script not very
useful for checking the currently checked out branch, as git will error
that the branch is already checked out. Add the "--detach" option to check
out the new temporary worktree in detached head mode. This is acceptable
because we aren't planning on working on the branch and just want a
checkout to do ABI checking from.
Allow use of persistent keys, including configuring them, importing and
exporting them, and destroying them.
When getting a slot using psa_get_key_slot, there are 3 scenarios that
can occur if the keys lifetime is persistent:
1. Key type is PSA_KEY_TYPE_NONE, no persistent storage entry:
- The key slot is treated as a standard empty key slot
2. Key type is PSA_KEY_TYPE_NONE, persistent storage entry exists:
- Attempt to load the key from persistent storage
3. Key type is not PSA_KEY_TYPE_NONE:
- As checking persistent storage on every use of the key could
be expensive, the persistent key is assumed to be saved in
persistent storage, the in-memory key is continued to be used.
Add new functions, psa_load_persistent_key(),
psa_free_persistent_key_data(), and psa_save_persistent_key(), for
managing persistent keys. These functions load to or save from our
internal representation of key slots. Serialization is a concern of the
storage backend implementation and doesn't abstraction-leak into the
lifetime management code.
An initial implementation for files is provided. Additional storage
backends can implement this interface for other storage types.
The persistent key implementation will be split across multiple
files as it will eventually be implementing multiple storage
backends. As these internal functions will need to be callable by
other files, we will add the headers in the library folder. This
commit adds this include location to the necessary scripts.
For tests, the library is added as an include location as testing
on-target with Mbed OS is not possible with paths including ".."

Even with a shallow clone of the repo where there are no tags available
to version with, don't error and instead show a unique abbreviated
commit hash as fallback.
OFB and CFB are streaming modes. XTS is a not a cipher mode but it
doesn't use a separate padding step. This leaves only CBC as a block
cipher mode that needs a padding step.
Since CBC is the only mode that uses a separate padding step, and is
likely to remain the only mode in the future, encode the padding mode
directly in the algorithm constant, rather than building up an
algorithm value from a chaining mode and a padding mode. This greatly
simplifies the interface as well as some parts of the implementation.
Create a tarball-based ditribution of the Mbed Crypto source code using the
code from Mbed TLS. Only export the files needed by Mbed Crypto to
implement the PSA Crypto API. Rename "mbedtls_*" and "MBEDTLS_*" symbols to
"mbedcrypto_*" and "MBEDCRYPTO_*".
The exported distribution can stand alone, without any Mbed TLS repository
needing to be present. "make test" will continue to work as before and will
run only the PSA Crypto test suite.
Print the symbolic name corresponding to a numerical value.
Supported types: status values, algorithms, elliptic curves,
key types, key usage masks.
The program is partly generated from parsing psa/crypto.h with a few
hard-coded assumptions. This isn't ideal but it works and requires
little machinery.
We failed check-names.sh due to using a define which wasn't described or
defined anywhere. Even though we won't realistically enable
MBEDTLS_PSA_CRYPTO_SPM via the configuration system (and will do it from
PSA Crypto SPM tooling instead), add a description of the configuration to
config.h as good practice. Exclude MBEDTLS_PSA_CRYPTO_SPM from the "full"
configuration as well.

Motivation is similar to NO_UDBL_DIVISION.
The alternative implementation of 64-bit mult is straightforward and aims at
obvious correctness. Also, visual examination of the generate assembly show
that it's quite efficient with clang, armcc5 and arm-clang. However current
GCC generates fairly inefficient code for it.
I tried to rework the code in order to make GCC generate more efficient code.
Unfortunately the only way to do that is to get rid of 64-bit add and handle
the carry manually, but this causes other compilers to generate less efficient
code with branches, which is not acceptable from a side-channel point of view.
So let's keep the obvious code that works for most compilers and hope future
versions of GCC learn to manage registers in a sensible way in that context.

While the old name is explicit and aligned with the RFC, it's also very long,
so with the mbedtls_ prefix prepended we get a 31-char prefix to each
identifier, which quickly conflicts with our 80-column policy.
The new name is shorter, it's what a lot of people use when speaking about
that construction anyway, and hopefully should not introduce confusion at
it seems unlikely that variants other than 20/1305 be standardised in the
foreseeable future.
This implementation is based off the description in RFC 7539.
The ChaCha20 code is also updated to provide a means of generating
keystream blocks with arbitrary counter values. This is used to
generated the one-time Poly1305 key in the AEAD construction.
