Teppo Järvelin 91d7938761 Changed every memcpy to SCA equivalent mbedtls_platform_memcpy 
This makes physical attacks more difficult.
 2019-10-30 14:07:04 +02:00
Manuel Pégourié-Gonnard 7a346b866c Replace memset() with mbedtls_platform_memset() 
Steps:

1. sed -i 's/\bmemset(\([^)]\)/mbedtls_platform_memset(\1/g' library/*.c tinycrypt/*.c include/mbedtls/*.h scripts/data_files/*.fmt

2. Manually edit library/platform_util.c to revert to memset() in the
implementations of mbedtls_platform_memset() and mbedtls_platform_memcpy()

3. egrep -n '\<memset\>' library/*.c include/mbedtls/*.h tinycrypt/*.c
The remaining occurrences are in three categories:
    a. From point 2 above.
    b. In comments.
    c. In the initialisation of memset_func, to be changed in a future commit.

Hanno Becker d6028a1894 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.

Janos Follath 7dadc2f259 ECP: Prevent freeing a buffer on stack 
The function ecp_mod_koblitz computed the space for the result of a
multiplication optimally for that specific case, but unfortunately
the function mbedtls_mpi_mul_mpi performs a generic, suboptimal
calculation and needs one more limb for the result. Since the result's
buffer is on the stack, the best case scenario is that the program
stops.

This only happened on 64 bit platforms.

Fixes #569

Manuel Pégourié-Gonnard 0223ab9d38 Fix macroization of inline in C++ 
When compiling as C++, MSVC complains about our macroization of a keyword.
Stop doing that as we know inline is always available in C++

Manuel Pégourié-Gonnard 20af64dc2c Still need to #define inline for MSVC 
I only tested with VS2015 earlier, but previous versions apparently still
don't know that standard C99 keyword though it's documented on MSDN...

Manuel Pégourié-Gonnard 2505528be4 Rm obsolete defines for inline wiht MSVC 
The "inline" keyword is supported since Visual Studio 2005 according to MSDN,
and we require Visual Studio 2010 or higher.
