Paul Bakker 66fdf34e81 Add MBEDTLS_FS_IO guard on default NV seed defines in platform.h
The default implementation won't work without MBEDTLS_FS_IO, so
leave undefined otherwise.

Paul Bakker d5c9f6d226 Automatically update NV seed on initial entropy run
Update the NV entropy seed before generating any entropy for outside
use. The reason this is triggered here and not in mbedtls_entropy_init(),
is that not all entropy sources mights have been added at that time.
2016-06-10 19:42:14 +01:00
Paul Bakker 9988d6bbd9 Introduce mbedtls_nv_seed_poll() entropy polling function 2016-06-10 19:42:14 +01:00
Paul Bakker cf0a9f96c5 Introduce platform-layer functions for reading/writing seed from NV
Introduces mbedtls_nv_seed_read() and mbedtls_nv_seed_write().

The platform-layer functions are only available when
MBEDTLS_ENTROPY_NV_SEED is enabled.

Janos Follath f93b8bc2e0 Add requirements for the entropy safety switch in documentation. 2016-06-09 13:54:15 +01:00
Janos Follath 53de78444c Add entropy safety switch.
Add a switch that turns entropy collecting off entirely, but enables
mbed TLS to run in an entirely unsafe mode. Enables to test mbed TLS
on platforms that don't have their entropy sources integrated yet.

James Cowgill c788b4cb5a Fix segfault on x32 by using better register constraints in bn_mul.h
On x32, pointers are only 4-bytes wide and need to be loaded using the "movl"
instruction instead of "movq" to avoid loading garbage into the register.

The MULADDC routines for x86-64 are adjusted to work on x32 as well by getting
gcc to load all the registers for us in advance (and storing them later) by
using better register constraints. The b, c, D and S constraints correspond to
the rbx, rcx, rdi and rsi registers respectively.

  the selected type in handshake->cert_type, but that field was never accessed
afterwards. Since handshake_params is now an internal type, we can remove that
field without breaking the ABI.

Manuel Pégourié-Gonnard 325ce093f9 Give better error messages for semi-portable parts
Previously it was failing with errors about headers not found, which is
suboptimal in terms of clarity. Now give a clean error with pointer to the
documentation.

Do the checks in the .c files rather than check_config.h as it keeps them
closer to the platform-specific implementations.

Manuel Pégourié-Gonnard d13b9507b3 Improve documentation of some SSL callbacks

what was specific to our implementation.

Manuel Pégourié-Gonnard 76da60c56e Fix doxygen warnings for generic names in config.h
When we use the same documentation for a list of #defines, we used to use a
generic name in the \def command. Use the first name of the list instead so
that doxygen stops complaining, and mention the generic name in the longer
description.

This is not entirely satisfactory as the full list of macros will not be
included in the generated doc, but it's still an improvement as at least the
first macro is documented now, with a hint that there are others.

Manuel Pégourié-Gonnard e2e25e7427 DTLS: avoid dropping too many records
When the peer retransmits a flight with many record in the same datagram, and
we already saw one of the records in that datagram, we used to drop the whole
datagram, resulting in interoperability failure (spurious handshake timeouts,
due to ignoring record retransmitted by the peer) with some implementations
(issues with Chrome were reported).

So in those cases, we want to only drop the current record, and look at the
following records (if any) in the same datagram. OTOH, this is not something
we always want to do, as sometime the header of the current record is not
reliable enough.

This commit introduces a new return code for ssl_parse_header() that allows to
distinguish if we should drop only the current record or the whole datagram,
and uses it in mbedtls_ssl_read_record()

Manuel Pégourié-Gonnard eef142d753 Depend on ECJPAKE key exchange, not module
This is more consistent, as it doesn't make any sense for a user to be able to
set up an EC J-PAKE password with TLS if the corresponding key exchange is
disabled.

Arguably this is what we should de for other key exchanges as well instead of
depending on ECDH_C etc, but this is an independent issue, so let's just do
the right thing with the new key exchange and fix the other ones later. (This
is a marginal issue anyway, since people who disable all ECDH key exchange are
likely to also disable ECDH_C in order to minimize footprint.)
