It was failing to set the key in the ENCRYPT direction before encrypting.
This just happened to work for GCM and CCM.
After re-encrypting, compare the length to the expected ciphertext
length not the plaintext length. Again this just happens to work for
GCM and CCM since they do not perform any kind of padding.
The CA callback changes introduce mbedtls_calloc() and
mbedtls_free() to ssl_client2 and ssl_server2, which
wasn't defined unless MBEDTLS_PLATFORM_C was set.
So far, there were the following CRT verification functions:
- `mbedtls_x509_crt_verify()` -- no profile, no restartable ECC
- `mbedtls_x509_crt_verify_with_profile()` -- profile, no restartable ECC
- `mbedtls_x509_crt_verify_restartable()` -- profile, restartable ECC
all publicly declared and offering increasing functionality.
On the implementation-side,
- `mbedtls_x509_crt_verify()` resolves to
a call to `mbedtls_x509_crt_verify_with_profile()` setting
the profile to `NULL`, and
- `mbedtls_x509_crt_verify_with_profile()`
resolves to a call to ``mbedtls_x509_crt_verify_restartable()`
setting the ECC restart context to NULL.
This commit adds two more functions to this zoo:
- `mbedtls_x509_crt_verify_with_cb()`
- `x509_crt_verify_restartable_cb()`
Here, `mbedtls_x509_crt_verify_with_cb()` is similar to
`mbedtls_x509_crt_verify_with_profile()` but uses a CA callback
instead of a static CA list, and no restart context.
`x509_crt_verify_restartable_cb()` is similar to
`mbedtls_x509_crt_verify_restartable()` but allows to either use
a static list of trusted CAs _or_ a trusted CA callback.
On the implementation-side,
- the body of `mbedtls_x509_crt_verify_restartable()` is moved to
`x509_crt_verify_restartable_cb()`, and the new version of
`mbedtls_x509_crt_verify_restartable()` just resolves to
`x509_crt_verify_restartable_cb()` with the trusted CA callback
set to NULL.
- The new function `mbedtls_x509_crt_verify_with_cb()`
forward to `x509_crt_verify_restartable_cb()` with the restart
context set to `NULL`.
There's no change to the implementation yet, and in particular,
`mbedtls_x509_crt_verify_with_cb()` isn't yet usable.
Resolve conflicts actions:
- Reject path changes to config.h
- Reject submodule-related changes in build scripts (Makefile,
CMakeLists.txt)
- Add oid test suite to list of tests in tests/CMakeLists.txt,
rejecting any test filtering related changes (which TLS uses to avoid
duplicating crypto tests)
- Add legacy ECDH test to all.sh without including
all.sh tests that depend on SSL

all.sh: Generate seedfile for crypto submodule tests
Update crypto submodule to test with private headers
tests: Use globbing in test suite exclusion list
Update crypto submodule to Mbed Crypto development
tests: Test crypto via the crypto submodule
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.
Some tests use internal-only header files, which are stored in the
'library' folder, and therefore need the library folder passed in on the
include path. For non-submoudle builds, this is set globally in the
top-level CMakeLists.txt file. For submodule builds, this is set through
target includes to a path only meaningful when Mbed Crypto is built as a
submodule.
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.
Since there is now a single storage backend, we don't need a backend
interface. Make the functions that were declared in
psa_crypto_storage_backend.h and are now both defined and used in
psa_crypto_storage.c static, except for psa_is_key_present_in_storage
which is used by the gray-box tests and is now declared in
psa_crypto_storage.h.
Since the ITS API has stabilized and we don't plan to make use of more
than ITS, we don't need an abstraction layer between key storage and
key storage over ITS. Merge the ITS code into the generic storage
module.
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.
