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.
```
git rm $(git status -s | sed -n 's/^DU //p')
git reset -- $(git status -s | sed -n 's/^D //p')
git checkout -- $(git status -s | sed -n 's/^ D //p')
git add -- $(git status -s | sed -n 's/^UD //p')
```
Individual files with conflicts:
* `3rdparty/everest/library/Hacl_Curve25519_joined.c`: spurious conflict because git mistakenly identified this file as a rename. Keep our version.
* `README.md`: conflict due to their change in a paragraph that doesn't exist in our version. Keep our version of this paragraph.
* `docs/architecture/Makefile`: near-identical additions. Adapt the definition of `all_markdown` and include the clean target.
* `doxygen/input/docs_mainpage.h`: conflict in the version number. Keep our version number.
* `include/mbedtls/config.h`: two delete/modify conflicts. Keep the removed chunks out.
* `library/CMakeLists.txt`: discard all their changes as they are not relevant.
* `library/Makefile`:
* Discard the added chunk about the crypto submodule starting with `INCLUDING_FROM_MBEDTLS:=1`.
* delete/modify: keep the removed chunk out.
* library build: This is almost delete/modify. Their changes are mostly not applicable. Do keep the `libmbedcrypto.$(DLEXT): | libmbedcrypto.a` order dependency.
* `.c.o`: `-o` was added on both sides but in a different place. Change to their place.
* `library/error.c`: to be regenerated.
* `library/version_features.c`: to be regenerated.
* `programs/Makefile`: Most of the changes are not relevant. The one relevant change is in the `clean` target for Windows; adapt it by removing `/S` from our version.
* `programs/test/query_config.c`: to be regenerated.
* `scripts/config.py`: added in parallel on both sides. Keep our version.
* `scripts/footprint.sh`: parallel changes. Keep our version.
* `scripts/generate_visualc_files.pl`: one delete/modify conflict. Keep the removed chunks out.
* `tests/Makefile`: discard all of their changes.
* `tests/scripts/all.sh`:
* `pre_initialize_variables` add `append_outcome`: add it.
* `pre_initialize_variables` add `ASAN_CFLAGS`: already there, keep our version.
* `pre_parse_command_line` add `--no-append-outcome`: add it.
* `pre_parse_command_line` add `--outcome-file`: add it.
* `pre_print_configuration`: add `MBEDTLS_TEST_OUTCOME_FILE`.
* Several changes in SSL-specific components: keep our version without them.
* Several changes where `config.pl` was changed to `config.py` and there was an adjacent difference: keep our version.
* Changes regarding the inclusion of `MBEDTLS_MEMORY_xxx`: ignore them here, they will be normalized in a subsequent commit.
* `component_test_full_cmake_gcc_asan`: add it without the TLS tests.
* `component_test_no_use_psa_crypto_full_cmake_asan`: keep the fixed `msg`, discard other changes.
* `component_test_memory_buffer_allocator_backtrace`, `component_test_memory_buffer_allocator`: add them without the TLS tests.
* `component_test_m32_everest`: added in parallel on both sides. Keep our version.
* `tests/scripts/check-names.sh`, `tests/scripts/list-enum-consts.pl`, `tests/scripts/list-identifiers.sh`, ``tests/scripts/list-macros.sh`: discard all of their changes.
* `tests/scripts/test-ref-configs.pl`: the change in the conflict is not relevant, so keep our version there.
* `visualc/VS2010/*.vcxproj`: to be regenerated.
Regenerate files:
```
scripts/generate_visualc_files.pl
git add visualc/VS2010/*.vcxproj

git add library/version_features.c
scripts/generate_query_config.pl
git add programs/test/query_config.c
```
Rejected changes in non-conflicting files:
* `CMakeLists.txt`: discard their addition which has already been side-ported.
* `doxygen/mbedtls.doxyfile`: keep the version number change. Discard the changes related to `../crypto` paths.
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.
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.

All sample and test programs had a definition of mbedtls_param_failed.
This was necessary because we wanted to be able to build them in a
configuration with MBEDTLS_CHECK_PARAMS set but without a definition
of MBEDTLS_PARAM_FAILED. Now that we activate the sample definition of
MBEDTLS_PARAM_FAILED in config.h when testing with
MBEDTLS_CHECK_PARAMS set, this boilerplate code is no longer needed.
There is some commented out X.509 certificate writing code present in
rsa_genkey. It looks like it has been commented out since the beginning
of time. Let's remove it, since commented out code is not in good style.
These examples rely on the NET module, which we want to remove. In
theory we could remove just the dependency, but we decided to remove the
whole example because:
- They showcase some bad crypto: custom, undocumented protocol (not
obviously broken though, apart from authenticating only one side);
hard-coded limit of 512-bit size for the DH modulus (2048 is the
recommended minimum these days); direct use of the shared secret as a
key (instead of applying a KDF); encryption with ECB, custom
parameters and the client not having the ability to verify them.
- The programs use the DH API in the same way that TLS does, so they
have limited demonstration value.
- The programs only show finite-field DH, which is not used all that
much these days. What people want to see is mostly ECDH.
Additional changes to temporarily enable running tests:
ssl_srv.c and test_suite_ecdh use mbedtls_ecp_group_load instead of
mbedtls_ecdh_setup
test_suite_ctr_drbg uses mbedtls_ctr_drbg_update instead of
mbedtls_ctr_drbg_update_ret
The previous prototype gave warnings are the strings produced by #cond and
__FILE__ are const, so we shouldn't implicitly cast them to non-const.
While at it modifying most example programs:
- include the header that has the function declaration, so that the definition
can be checked to match by the compiler
- fix whitespace
- make it work even if PLATFORM_C is not defined:
- CHECK_PARAMS is not documented as depending on PLATFORM_C and there is
no reason why it should
- so, remove the corresponding #if defined in each program...
- and add missing #defines for mbedtls_exit when needed
The result has been tested (make all test with -Werror) with the following
configurations:
- full with CHECK_PARAMS with PLATFORM_C
- full with CHECK_PARAMS without PLATFORM_C
- full without CHECK_PARAMS without PLATFORM_C
- full without CHECK_PARAMS with PLATFORM_C
Additionally, it has been manually tested that adding
mbedtls_aes_init( NULL );
near the normal call to mbedtls_aes_init() in programs/aes/aescrypt2.c has the
expected effect when running the program.
The sample programs require an additional handler function of
mbedtls_param_failed() to handle any failed parameter validation checks enabled
by the MBEDTLS_CHECK_PARAMS config.h option.
Some sample programs access structure fields directly. Making these work is
desirable in the long term, but these are not essential for the core
functionality in non-legacy mode.
When using a primality testing function the tolerable error rate depends
on the scheme in question, the required security strength and wether it
is used for key generation or parameter validation. To support all use
cases we need more flexibility than what the old API provides.
