Manuel Pégourié-Gonnard ab9c5fd9b3 cmac: avoid useless wrapping of function
probably a leftover from an earlier stage

Manuel Pégourié-Gonnard 2c06306364 cmac: some more padding-related tune-ups
- use one less temporary buffer
- pedantic: in_len + 15 was a potential overflow
- use a more explicit name instead of 'flag'
- Mn was a bit misleading

Manuel Pégourié-Gonnard d2c3d3eddb cmac: clean up padding function and comments 2016-10-05 14:19:14 +01:00
Manuel Pégourié-Gonnard 475f06f609 cmac: make subkey gen more constant-time
The previous version had secret-dependent memory accesses. While it was
probably not an issue in practice cause the two bytes of the array are
probably on the same cache line anyway, as a matter of principle this should
be avoided.

Manuel Pégourié-Gonnard 690083c21d cmac: improve argument order and naming
- always use the pattern "buffer, length"
- avoid using unqualified "length" as a name when there are more than one

Andres AG 788aa4a812 Rename net.{c,h} to net_sockets.{c,h}
The library/net.c and its corresponding include/mbedtls/net.h file are
renamed to library/net_sockets.c and include/mbedtls/net_sockets.h
respectively. This is to avoid naming collisions in projects which also
have files with the common name 'net'.

Andres AG f9113194af Allow the entry_name size to be set in config.h
Allow the size of the entry_name character array in x509_crt.c to be
configurable through a macro in config.h. entry_name holds a
path/filename string. The macro introduced in
MBEDTLS_X509_MAX_FILE_PATH_LEN.

Andres Amaya Garcia a928e67278 Documentation and entropy self test changes (#610)
Ensure that the entropy self test always fails whenever
MBEDTLS_TEST_NULL_ENTROPY is defined. This is because the option is
meant to be for testing and development purposes rather than production
quality software. Also, this patch enhances the documentation for
mbedtls_entropy_source_self_test() and mbedtls_entropy_self_test().

Andres AG e7723ec284 Make entropy bias self test poll multiple times
Instead of polling the hardware entropy source a single time and
comparing the output with itself, the source is polled at least twice
and make sure that the separate outputs are different.

Andres AG b34e42e69e Add a new self test to entropy module
The self test is a quick way to check at startup whether the entropy
sources are functioning correctly. The self test only polls 8 bytes
from the default entropy source and performs the following checks:

- The bytes are not all 0x00 or 0xFF.
- The hardware does not return an error when polled.
- The entropy does not provide data in a patter. Only check pattern
  at byte, word and long word sizes.

Paul Bakker c7d6bd4b5f Add mbedtls_asn1_write_len() support for 3 and 4 byte lengths

(which were not covered before)

Simon Butcher 23e9778684 Adds missing conditions for platform time
In platform.c, made the time functions dependent on the configuration
MBEDTLS_HAVE_TIME to fix a build break where the functions could be
built but the mbedtls_time_t was not defined.

Simon Butcher b5b6af2663 Puts platform time abstraction into its own header
Separates platform time abstraction into it's own header from the
general platform abstraction as both depend on different build options.
(MBEDTLS_PLATFORM_C vs MBEDTLS_HAVE_TIME)

Simon Butcher 1ceab6e43a Adds a check and warning for the null entropy option
If the option MBEDTLS_TEST_NULL_ENTROPY is enabled, the cmake generated
makefile will generate an error unless a UNSAFE_BUILD switch is also enabled.

Equally, a similar warning will always be generated if the Makefile is built,
and another warning is generated on every compilation of entropy.c.

This is to ensure the user is aware of what they're doing when they enable the
null entropy option.

Simon Butcher ab5df40054 Rename the 'no entropy' feature to MBEDTLS_TEST_NULL_ENTROPY
Following review and for clarity, changed the name of the feature to 'null

Paul Bakker fc9c7c8bf4 Initial entropy run should be context specific
Otherwise test influence each other.
Is a change to the context but only if the NV seed feature is enabled
2016-06-10 19:42:15 +01:00
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.
