Choosing SP and SP math was resulting in only integer.c being used.
Fixed now.
Reorder realloc calls for memory logging to ensure scripts can match
allocate and free calls.
Add a define WOLFSSL_CHECK_MEM_ZERO to turn on code that checks that
memory that must be zeroized before going out of use is zero.
Everytime sensitive data is put into a allocated buffer or stack buffer;
the address, its length and a name is stored to be checked later.
Where the stack buffer is about to go out of use, a call is added to
check that the required parts are zero.
wc_MemZero_Add() adds an address with length and name to a table of
addressed to be checked later.
wc_MemZero_Check() checks that the memory associated with the address is
zeroized where required.
mp_memzero_add() adds mp_int's data pointer with length and name to
table.
mp_memzero_check() checks that the data pointer is zeroized where
required.
Freeing memory will check the address. The length was prepended on
allocation.
Realloction was changed for WOLFSSL_CHECK_MEM_ZERO to perform an
allocate, check, copy, free.
Adds support for embOS memory and mutex functions. Also adds support for
emNET's error codes, it uses a BSD compatible TCP/IP stack for network
functions.
There is no easy native way to detect that you are compiling with emNET
or embOS so these require the user to define WOLFSSL_EMBOS /
WOLFSSL_EMNET.
