* Adjust all accesses to EVP_MD_CTX to use accessor functions.Richard Levitte2015-12-0730-283/+380

* Adapt HMAC to the EVP_MD_CTX changesRichard Levitte2015-12-075-39/+64
| | | | | | | | | | | | | This change required some special treatment, as HMAC is intertwined with EVP_MD. For now, all local HMAC_CTX variables MUST be initialised with HMAC_CTX_EMPTY, or whatever happens to be on the stack will be mistaken for actual pointers to EVP_MD_CTX. This will change as soon as HMAC_CTX becomes opaque. Also, since HMAC_CTX_init() can fail now, its return type changes from void to int, and it will return 0 on failure, 1 on success.

* Tighten up BN_with_flags usage and avoid a reachable assertMatt Caswell2015-11-267-129/+194
| | | | | | | | | | | | | | | | | | The function rsa_ossl_mod_exp uses the function BN_with_flags to create a temporary copy (local_r1) of a BIGNUM (r1) with modified flags. This temporary copy shares some state with the original r1. If the state of r1 gets updated then local_r1's state will be stale. This was occurring in the function so that when local_r1 was freed a call to bn_check_top was made which failed an assert due to the stale state. To resolve this we must free local_r1 immediately after we have finished using it and not wait until the end of the function. This problem prompted a review of all BN_with_flag usage within the codebase. All other usage appears to be correct, although often not obviously so. This commit refactors things to make it much clearer for these other uses. Reviewed-by: Emilia Käsper <emilia@openssl.org>

* Async error handling and MacOS/X fixesViktor Dukhovni2015-11-227-50/+50
| | | | | | | | | | | | | | | | | | | In the async code for MacOS/X define _XOPEN_SOURCE (if not already defined) as early as possible. We must do this before including any header files, because on MacOS/X <stlib.h> includes <signal.h> which includes <ucontext.h>. If we delay defining _XOPEN_SOURCE and include <ucontext.h> after various system headers are included, we are very likely to end up with the wrong (truncated) definition of ucontext_t. Also, better error handling and some code cleanup in POSIX fibre construction and destruction. We make sure that async_fibre_makecontext() always initializes the fibre to a state that can be freed. For all implementations, check for error returns from async_fibre_makecontext(). Reviewed-by: Matt Caswell <matt@openssl.org>

| | | | | | | | | | We were using _pipe to create a pipe on windows. This uses the "int" type for its file descriptor for compatibility. However most windows functions expect to use a "HANDLE".

* Fix async deadlock problemMatt Caswell2015-11-211-0/+17
| | | | | | | | | The rand code can aquire locks and then attempt crypto operations.
