e02e02f203 Change sha512 output type from an array to a pointer
The output parameter of mbedtls_sha512_finish_ret and mbedtls_sha512_ret
now has a pointer type rather than array type. This removes spurious
warnings in some compilers when outputting a SHA-384 hash into a
48-byte buffer.

3352a53475 Modify config option for SHA384.
Although SHA512 is currently required to enable SHA384, this
is expected to change in the future. This commit is an
intermediate step towards fully separating SHA384 and SHA512.

check_config is the only module which enforces that SHA512 is
enabled together with SHA384.

Zeroize internal buffers and variables in PKCS and SHA
Zeroising of local buffers and variables which are used for calculations in
mbedtls_pkcs5_pbkdf2_hmac() and mbedtls_internal_sha*_process() functions
to erase sensitive data from memory.
Checked all function for possible missing zeroisation in PKCS and SHA.

1eeca41472 Improve macro hygiene
This commit improves hygiene and formatting of macro definitions
throughout the library. Specifically:
- It adds brackets around parameters to avoid unintended
  interpretation of arguments, e.g. due to operator precedence.
- It adds uses of the `do { ... } while( 0 )` idiom for macros that
  can be used as commands.

c756049dc3 Move SHA512_VALIDATE[_RET] outside of MBEDTLS_SHA512_ALT guard
Somehow, mbedtls_sha512_ret() is defined even if MBEDTLS_SHA512_ALT
is set, and it is using SHA512_VALIDATE_RET. The documentation should
be enhanced to indicate that MBEDTLS_SHA512_ALT does _not_ replace
the entire module, but only the core SHA-512 functions.

1cc1fb0599 Fix Lucky 13 cache attack on MD/SHA padding
The basis for the Lucky 13 family of attacks is for an attacker to be able to
distinguish between (long) valid TLS-CBC padding and invalid TLS-CBC padding.
Since our code sets padlen = 0 for invalid padding, the length of the input to
the HMAC function gives information about that.

Information about this length (modulo the MD/SHA block size) can be deduced
from how much MD/SHA padding (this is distinct from TLS-CBC padding) is used.
If MD/SHA padding is read from a (static) buffer, a local attacker could get
information about how much is used via a cache attack targeting that buffer.

Let's get rid of this buffer. Now the only buffer used is the internal MD/SHA
one, which is always read fully by the process() function.

041039f81e MD: Make deprecated functions not inline
In 2.7.0, we replaced a number of MD functions with deprecated inline
versions. This causes ABI compatibility issues, as the functions are no
longer guaranteed to be callable when built into a shared library.
Instead, deprecate the functions without also inlining them, to help
maintain ABI backwards compatibility.

9e4f77c606 New MD API: rename functions from _ext to _ret
The _ext suffix suggests "new arguments", but the new functions have
the same arguments. Use _ret instead, to convey that the difference is
that the new functions return a value.

614c689e05 Add int return values to SHA-512 function calls
The following function calls are being deprecated to introduce int
return values.
    * mbedtls_sha512()
    * mbedtls_sha512_starts()
    * mbedtls_sha512_update()
    * mbedtls_sha512_finish()
    * mbedtls_sha512_process()
The return codes can be used to return error values. This is important
when using hardware accelerators.
