Before moving to the new release of Mbed TLS, this moves the default imported
version of Mbed TLS to the development branch, and will import the HEAD of the
branch, not just a specific release.
This commit makes the storage configurations - setting
MBEDTLS_PSA_CRYPTO_STORAGE_C, MBEDTLS_PSA_CRYPTO_STORAGE_ITS_C and unsetting
MBEDTLS_PSA_CRYPTO_STORAGE_FILE_C - dependent on the PSA label being defined for
the target.
Previously these symbols were always defined for all platforms which could
cause problems for targets that don't yet support PSA.
This commit makes the repo used to import new Mbed TLS versions into Mbed OS
a parameter, to allow CI scripts (and any other script or users) to specify
specific repos to use for testing.
Reduce the default size of `MBEDTLS_MPI_MAX_SIZE` to 512 bytes,
as the default 1024 consumes much stack, and supporting RSA 4096 bit
may suffice at the moment.
The new PSA-aware Mbed TLS importer script calls `config.pl` on the
Mbed TLS config.h to set the PSA configuration option
MBEDTLS_PSA_CRYPTO_STORAGE_C which isn't documented in config.h.
config.pl therefore fails, and so does the importer.
This commit fixes this by calling `config.pl` with the `--force`
option which amends the given `config.h` by a `#define` for the
requested option if the option isn't present in the file.
Although "nv_seed" is one of "entropy", it doesn't included to the "!defined" lineup in the following config file.
Therefore, when MBEDTLS_ENTROPY_NV_SEED is defined, it is accidently invoked "mbedtls/config-no-entropy.h".
mbed-os\features\mbedtls\inc\mbedtls\config.h
I think that correct processing should go to line 47, not line 40.
Enable the compile-time option MBEDTLS_AES_ROM_TABLES in the mbed TLS
main config.h file in mbed OS. This option has the effect of labelling
the AES tables as 'const' so they are placed in ROM, which saves some
RAM space.
The crypto hardware acceleration might require defining a lot of mbed
TLS specific macros. Enumerating all of them in `targets.json` creates
too much noise, therefore we move it into a target specific mbed TLS
header.
The target with crypto hardware acceleration has to
- indicate its capability in `targets.json` by adding "CRYPTO"
to the "device_has" section
- has to define his crypto hardware acceleration related macros
in an `mbedtls_device.h` header
- place the `mbedtls_device.h` file in the
`features/mbedtls/targets/TARGET_XXXX`
directory specific to the target
Update the current version of mbed TLS with the development HEAD of the
mbed TLS project repository. This mostly includes the latest CMAC
feature. Also, update the version in the importer Makefile and
VERSION.txt with the hash of the mbed TLS commit that was sync'ed.
