Executed ./scripts/bump_version.sh --version 2.25.0 --so-crypto 6
Increasing the SO version of the crypto library, because the openless
API improvement came with API/ABI incompatibilities. For example
- the size of psa_key_handle_t changed
- the type of a parameter in 18 public functions has changed from
psa_key_handle_t to mbedtls_svc_key_id_t

This algorithm replaces the pre-existing stream cipher algorithms.
The underlying stream cipher is determined by the key type.

In order to remove large buffers from the stack, the der data is written
into the same buffer that the pem is eventually written into, however
although the pem data is zero terminated, there is now data left in the
buffer after the zero termination, which can cause
mbedtls_x509_crt_parse to fail to parse the same buffer if passed back
in. Patches also applied to mbedtls_pk_write_pubkey_pem, and
mbedtls_pk_write_key_pem, which use similar methods of writing der data
to the same buffer, and tests modified to hopefully catch any future
regression on this.

The internal functions mbedtls_cipher_aead_{encrypt,decrypt} reject
unsupported algorithms, so there's no need for an additional check in
the legacy wrappers.

Make sure that if a buffer is allowed to be empty, a null pointer is
accepted if the buffer length is 0. This was already the case for most
but not all arguments to mbedtls_cipher_auth_{en,de}crypt{,_ext}.
Make sure to pass NULL for an empty buffer in the tests.

fix_negative allocates memory for its result. The calling site didn't
check the return value, so an out-of-memory error could lead to an
incorrect calculation. Fix this.

Work in progress: next step is to test it!
Extract the part that is common with non-ext version to a new internal
function. (We can't just use the non-ext version for that, as it's going to be
deprecated.)
Currently the NIST_KW part is somewhat duplicated between the ext
and non-ext versions, but that's OK because it will soon be removed from the
non-ext version.

Check that the exponent and modulus is below `MBEDTLS_MPI_MAX_BITS` before
performing a time expensive operation (modular exponentiation). This prevents
a potential DoS from Diffie-Hellman computations with extremely
large key sizes.

Removed unecessary checks on the ALG_SHA_224 and ALG_SHA_384 since
those are handled in config_psa.h by ensuring the correct _C is
included. Reformatted config_psa.h to be alphabetical and made the
assignments line up correctly for consistency. Fixed the guards
for ALG_SHA_224 and ALG_SHA_384 to be correct in the crypto library
source.

Add missing tag check for algorithm parameters when comparing the
signature in the description part of the cert against the actual
signature whilst loading a certificate. This was found by a
certificate (created by fuzzing) that openssl would not verify, but
mbedtls would.

mbedtls_ctr_drbg_set_reseed_interval() and
mbedtls_hmac_drbg_set_reseed_interval() can now be called before
their seed functions and the reseed_interval value will persist.
Previously it would be overwritten with the default value.
*_drbg_reseed_interval is now set in init() and free().
mbedtls_ctr_drbg_free() and mbedtls_hmac_drbg_free() now
reset the drbg context to the state immediately after init().
Tests:
- Added test to check that DRBG reseeds when reseed_counter
reaches reseed_interval, if reseed_interval set before seed
and reseed_interval is less than MBEDTLS_CTR_DRBG_RESEED_INTERVAL.

`finish_sha384_t` was made more generic by using `unsigned char*`
instead of `unsigned char[48]` as the second parameter.
This change tries to make the function casting more robust against
future improvements of gcc analysis.

This commit fixes the same warning fixed by baeedbf9, but without
wasting RAM. By casting `mbedtls_sha512_finish_ret()`, `padbuf`
could be kept 48 bytes long without triggering any warnings.
Signed-off-by: Rodrigo Dias Correa <rodrigo@correas.us>
GCC 11 generated a warning because `padbuf` was too small to be
used as an argument for `mbedtls_sha512_finish_ret`. The `output`
parameter of `mbedtls_sha512_finish_ret` has the type
`unsigned char[64]`, but `padbuf` was only 48 bytes long.
Even though `ssl_calc_finished_tls_sha384` uses only 48 bytes for
the hash output, the size of `padbuf` was increased to 64 bytes.

In GCC 11, parameters declared as arrays in function prototypes
cannot be declared as pointers in the function definition. The
same is true for the other way around.
The definition of `mbedtls_aes_cmac_prf_128` was changed to match
its public prototype in `cmac.h`. The type `output` was
`unsigned char *`, now is `unsigned char [16]`.
In `ssl_tls.c`, all the `ssl_calc_verify_*` variants now use pointers
for the output `hash` parameter. The array parameters were removed
because those functions must be compatible with the function pointer
`calc_verify` (defined in `ssl_internal.h`).
