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.
This commit removes all the static occurrencies of the function
mbedtls_zeroize() in each of the individual .c modules. Instead the
function has been moved to utils.h that is included in each of the
modules.
This commit returns to using constant macros instead of global variables for the DHM group constants. Further, macros
providing the binary encoding of the primes from RFC 3526 and RFC 7919 are added. The hex-string macros are deprecated.
Although the variable ret was initialised to an error, the
MBEDTLS_MPI_CHK macro was overwriting it. Therefore it ended up being
0 whenewer the bignum computation was successfull and stayed 0
independently of the actual check.

Update Changelog for DH params
Add test case for dh params with privateValueLength
accept PKCS#3 DH parameters with privateValueLength included
Conflicts:
library/dhm.c
library/dhm.c: accept (and ignore) optional privateValueLength for
PKCS#3 DH parameters.
PKCS#3 defines the ASN.1 encoding of a DH parameter set like this:
----------------
DHParameter ::= SEQUENCE {
prime INTEGER, -- p
base INTEGER, -- g
privateValueLength INTEGER OPTIONAL }
The fields of type DHParameter have the following meanings:
o prime is the prime p.
o base is the base g.
o privateValueLength is the optional private-value
length l.
----------------
See: ftp://ftp.rsasecurity.com/pub/pkcs/ascii/pkcs-3.asc
This optional parameter was added in PKCS#3 version 1.4, released
November 1, 1993.
dhm.c currently doesn't cope well with PKCS#3 files that have this
optional final parameter included. i see errors like:
------------
dhm_parse_dhmfile returned -0x33E6
Last error was: -0x33E6 - DHM - The ASN.1 data is not formatted correctly : ASN1 - Actual length differs from expected lengt
------------
You can generate PKCS#3 files with this final parameter with recent
versions of certtool from GnuTLS:
certtool --generate-dh-params > dh.pem
