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.
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.
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.
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.
It is used only by `mbedtls_sha512_process()`, and in case `MBEDTLS_SHA512_PROCESS_ALT` is defined, it still cannot be reused because of `static` declaration.
* mbedtls-1.3:
Use link-time garbage collection in memory.sh
scripts/memory.sh only work on Linux
Add missing 'const' on selftest data
Use only headers for doxygen (no doc in C files)
Add missing extern "C" guard in aesni.h
Fix compile error with renego disabled
Remove slow PKCS5 test
Stop checking key-cert match systematically
Make tests/*.sh runnable from anywhere
Update visual C files
