Gilles Peskine d919993b76 CTR_DRBG: deprecate mbedtls_ctr_drbg_update because it ignores errors
Deprecate mbedtls_ctr_drbg_update (which returns void) in favor of a
new function mbedtls_ctr_drbg_update_ret which reports error.

Nir Sonnenschein 85fcb58997 Refactor test code for CTR DRBG to clarify test functions
previously a single function was used for most test cases (ctr_drbg_validate) making it harder to understand what the exact scenario is as a result it was split into easier to understand functions.

Nir Sonnenschein 6275be3483 Re-factor test functions and add support for data_t parameters
the testing functions were re-factored so that the common code was extracted to a single static function (removing the need for unclear goto statements).
As part of the re-factor the test functions now use data_t for parameters (support for this was introduced in previous rebase),

Gilles Peskine 5ef5a9aeb4 ctr_drbg tests: unify validate functions
Unify the three existing validation functions (with prediction
resistance, with manual reseeding between generations, and with no
reseeding) into a single function that supports these three scenarios
plus a fourth one (reseed before the first generation).

The four supported scenarios cover the three scenarios from the
current CAVP test vectors (no reseed, reseed before generating,
prediction resistance) plus a fourth scenario used by the existing
test vectors (reseed after generating).

(cherry picked from commit cee9bedee6bc1a8e2b22fa8a31647b62ebb8a0a4)

Gilles Peskine 4c78665ccd ctr_drbg tests: new validation function that doesn't reseed
This is one of the test scenarios from the CAVP test vectors.

Gilles Peskine ef0624f791 ctr_drbg tests: make input sizes flexible
The ctr_drbg_validate_xxx test functions had hard-coded sizes for the
entropy and the output size. Generalize the sizes.

Keep track of the current entropy size.

Unhexify the expected output and compare with the actual output,
rather than hexifying the actual output and comparing the hex.

Reut Caspi e278b36461 Change mbedtls_entropy_func in tests to mbedtls_test_entropy_func
Change function in tests named mbedtls_entropy_func to
mbedtls_test_entropy_func to avoid getting error from the linker when
calling the mbedtls_entropy_func elsewhere.

Andres Amaya Garcia 6a54336897 Fix integer overflows in buffer bound checks
Fix potential integer overflows in the following functions:
  * mbedtls_md2_update() to be bypassed and cause
  * mbedtls_cipher_update()
  * mbedtls_ctr_drbg_reseed()
This overflows would mainly be exploitable in 32-bit systems and could
cause buffer bound checks to be bypassed.

Paul Bakker 534f82c77a Made ctr_drbg_init_entropy_len() non-static and defined 2013-06-25 16:47:55 +02:00
Paul Bakker 69e095cc15 - Changed the behaviour of x509parse_parse_crt for permissive parsing. Now returns the number of 'failed certificates' instead of having a switch to enable it.
- As a consequence all error code that were positive were changed. A lot of MALLOC_FAILED and FILE_IO_ERROR error codes added for different modules.
 - Programs and tests were adapted accordingly
