- Use nullness checks when calling weakly linked functions. - Avoid typedef for reasons described in Linux Kernel style guide. - Avoid enum in in Windows headers. Earlier in Cosmo's history all one hundred files in libc/nt/enum/ used to be enums and it resulted in gigabytes of DWARF data almost as large as everything else in the codebase combined. - Bitfields aren't our friends. They have frequent ABI breakages, inconsistent arithmetic across compilers, and different endianness between cpus. Compiler authors also haven't invested much roi into making bit fields go fast so they produce poor assembly. - Use memccpy() instead of strncpy() or snprintf() for length-bounded copying of C strings. strncpy() is a misunderstood function and snprintf() is awesome but memccpy() deserves more love. |

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
- 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.
