Hanno Becker f5106d54eb Don't declare and define gmtime()-mutex on Windows platforms 2018-09-06 12:09:56 +01:00
Hanno Becker 323d8019bf Correct preprocessor guards determining use of gmtime()
The previous code erroneously used gmtime_r() to implement
mbedtls_platform_gmtime() in case of a non-windows, non-unix system.

Hanno Becker cfeb70c6b9 gmtime: Remove special treatment for IAR
Previous commits attempted to use `gmtime_s()` for IAR systems; however,
this attempt depends on the use of C11 extensions which lead to incompatibility
with other pieces of the library, such as the use of `memset()` which is
being deprecated in favor of `memset_s()` in C11.

Hanno Becker 1841b0a11c Rename ssl_conf_datagram_packing() to ssl_set_datagram_packing()

apply to the SSL configuration.

Hanno Becker f4b010efc4 Limit MTU by maximum fragment length setting
By the standard (RFC 6066, Sect. 4), the Maximum Fragment Length (MFL)
extension limits the maximum record payload size, but not the maximum
datagram size. However, not inferring any limitations on the MTU when
setting the MFL means that a party has no means to dynamically inform
the peer about MTU limitations.

This commit changes the function ssl_get_remaining_payload_in_datagram()
to never return more than

MFL - { Total size of all records within the current datagram }

thereby limiting the MTU to MFL + { Maximum Record Expansion }.

Hanno Becker 283f5efe7d Buffering: Free future record epoch after each flight
The function ssl_free_buffered_record() frees a future epoch record, if
such is present. Previously, it was called in mbedtls_handshake_free(),
i.e. an unused buffered record would be cleared at the end of the handshake.
This commit moves the call to the function ssl_buffering_free() responsible
for freeing all buffering-related data, and which is called not only at
the end of the handshake, but at the end of every flight. In particular,
future record epochs won't be buffered across flight boundaries anymore,
and they shouldn't.
