Always pass a context object to entropy_dummy_source. This lets us
write tests that register more than one source and keep track of how
many times each one is called.
This caused problems when running multiple jobs at once, since
there was no target matching libmbedcrypto.so with the path
prefix. It only worked if it was built first, since such file was found.
Additionally, building of libmbedcrypto.so now waits for the static .a version.
Previously, recipes for both libmbedcrypto.a and libmbedcrypto.so could run
independently when running parallel jobs, which resulted in the .o files
being built twice. It could sometimes be a problem, since linking would start
when building one of the object files was still in progress (the previous one
existed). This in turn resulted in reading (and trying to link) a malformed file.
The "|" character is followed by "order-only-prerequisites", and in this case,
makes linking of the shared version of the library wait for the .a file.
Since it's guaranteed to be always built in the "all" target, it's fine to do that.
All of the .o files are only built once thanks to this change.
Get started on writing a change log file for Mbed Crypto. I went
through pull requests merged since the tag mbedcrypto-2.0.0 and up
to #75, i.e. commit 9ab7c07f1f.
* #277: Improve speed of PBKDF2 by caching the digest state of the passphrase
* #269: Add PSA API versioning
* #278: Fix on target test issues
* #286: Fix defgroup syntax for API version section
* #75: ASN.1 tests without x509
The documentation of HMAC_DRBG erroneously claimed that
mbedtls_hmac_drbg_set_entropy_len() had an impact on the initial
seeding. This is in fact not the case: mbedtls_hmac_drbg_seed() forces
the entropy length to its chosen value. Fix the documentation.
The documentation of CTR_DRBG erroneously claimed that
mbedtls_ctr_drbg_set_entropy_len() had an impact on the initial
seeding. This is in fact not the case: mbedtls_ctr_drbg_seed() forces
the initial seeding to grab MBEDTLS_CTR_DRBG_ENTROPY_LEN bytes of
entropy. Fix the documentation and rewrite the discussion of the
entropy length and the security strength accordingly.
Explain how MBEDTLS_CTR_DRBG_ENTROPY_LEN is set next to the security
strength statement, rather than giving a partial explanation (current
setting only) in the documentation of MBEDTLS_CTR_DRBG_ENTROPY_LEN.
NIST and many other sources call it a "personalization string", and
certainly not "device-specific identifiers" which is actually somewhat
misleading since this is just one of many things that might go into a
personalization string.
Improve the formatting and writing of the documentation based on what
had been done for CTR_DRBG.
Document the maximum size and nullability of some buffer parameters.
Document that a derivation function is used.
Document the security strength of the DRBG depending on the
compile-time configuration and how it is set up. In particular,
document how the nonce specified in SP 800-90A is set.
Mention how to link the ctr_drbg module with the entropy module.
* State explicit whether several numbers are in bits or bytes.
* Clarify whether buffer pointer parameters can be NULL.
* Explain the value of constants that are dependent on the configuration.
* origin/pr/2843: (26 commits)

Add invasive checks that peek at the stored persistent data after some
successful import, generation or destruction operations and after
reinitialization to ensure that the persistent data in storage has the
expected content.
Add a parameter to the p_validate_slot_number method to allow the
driver to modify the persistent data.
With the current structure of the core, the persistent data is already
updated. All it took was adding a way to modify it.
When registering a key in a secure element, go through the transaction
mechanism. This makes the code simpler, at the expense of a few extra
storage operations. Given that registering a key is typically very
rare over the lifetime of a device, this is an acceptable loss.
Drivers must now have a p_validate_slot_number method, otherwise
registering a key is not possible. This reduces the risk that due to a
mistake during the integration of a device, an application might claim
a slot in a way that is not supported by the driver.
