DESCRIPTION
Mbed TLS is a crypto library built by ARM that's been released
under a more permissive license than alternatives like OpenSSL
and is useful for interoperating with systems that require TLS

LOCAL CHANGES
- Strengthened server against DOS by removing expensive protections
for old Internet Explorer against Lucky Thirteen timing attacks.
- Reduce build+test latency from 15 seconds to 5 seconds.
- Features have been added that enable this library to produce SSL
certificates that can be used by Google Chrome. This required we
add featurces for editing Subject Alternative Names and Extended
Key Usage X.509 extension fields since upstream mbedtls can only
do that currently for Netscape Navigator.
- Local changes needed to be made to test_suite_ssl.datax due to it
not taking into consideration disabled features like DTLS.
- Local changes needed to be made to test_suite_x509parse.datax due
to the features we added for subject alternative name parsing.
- We've slimmed things down to meet our own specific local needs.
For example, we don't need the PSA code since we don't target ARM
hardware. We also don't need algorithms like camellia, blowfish,
ripemd, arc4, ecjpake, etc. We want security code that's simple,
readable, and easy to maintain. For example, the formally verified
eliptic curve diffie-helman code was 38 files and most of it was
dead code which could be consolidated into one < 1 kLOC file.
- The only breaking API change that's been made is to redefine int
arrays of things like long lists of ciphersuites to be uint8_t or
uint16_t instead when appropriate.
- Exported test code so it (a) doesn't have python as a build time
dependency, (b) doesn't print to stdout on success, (c) bundles
its dependencies inside a zip container so the tests are able to
run hermetically if the binary is scp'd to some machine, and (d)
doesn't have large amounts of duplicated generated code.
- Fix mbedtls_mpi_sub_abs() to not call malloc/free/memcpy since
it's called 11,124 times during as SSL handshake.
- Make P-256 and P-384 modulus goes 5x faster.
- Make chacha20 26% faster.
- Make base64 100x faster.
- Make gcm faster.
