* Remove #error from include files.Rich Salz2016-03-201-3/+1
| | | | | | | | Don't have #error statements in header files, but instead wrap the contents of that file in #ifndef OPENSSL_NO_xxx This means it is now always safe to include the header file. Reviewed-by: Richard Levitte <levitte@openssl.org>
* Fix a potential double free in EVP_DigestInit_exMatt Caswell2016-03-181-1/+3
| | | | | | | | | | There is a potential double free in EVP_DigestInit_ex. This is believed to be reached only as a result of programmer error - but we should fix it anyway. Issue reported by Guido Vranken. Reviewed-by: Richard Levitte <levitte@openssl.org>
* GH715: ENGINE_finish can take NULLRich Salz2016-02-251-13/+8
| | | | | | | Simplifies calling code. Also fixed up any !ptr tests that were nearby, turning them into NULL tests. Reviewed-by: Richard Levitte <levitte@openssl.org>

| | | | | | | Valgrind complains about using unitialized memory. So call OPENSSL_zalloc, not malloc. Reviewed-by: Richard Levitte <levitte@openssl.org>

* Fix a possible memleakRichard Levitte2016-01-021-0/+7
| | | | | | | | If there's a failure allocating md_data, the destination pctx will have a shared pointer with the source EVP_MD_CTX, which will lead to problems when either the source or the destination is freed. Reviewed-by: Stephen Henson <steve@openssl.org>

* Cleanup: rename EVP_MD_CTX_(create|init|destroy) to EVP_MD_CTX_(new|reset|free)Richard Levitte2015-12-071-9/+9
| | | | | | | | | Looking over names, it seems like we usually use names ending with _new and _free as object constructors and destructors. Also, since EVP_MD_CTX_init is now used to reset a EVP_MD_CTX, it might as well be named accordingly. Reviewed-by: Rich Salz <rsalz@openssl.org>
* Remove EVP_MD_CTX_cleanup and put its functionality into EVP_MD_CTX_initRichard Levitte2015-12-071-52/+44
| | | | | | | | | | | The idea is that with EVP_MD_CTX_create() and EVP_MD_CTX_destroy(), EVP_MD_CTX_cleanup and EVP_MD_CTX_init is not used the same as before. Instead, we need a single function that can be used to reinitialise an existing EVP_MD_CTX that's been created with EVP_MD_CTX_create() previously. Combining EVP_MD_CTX_cleanup and EVP_MD_CTX_init into that one function is the answer. Reviewed-by: Rich Salz <rsalz@openssl.org>

| | | | | | | | | | | | | There are header files in crypto/ that are used by a number of crypto/ submodules. Move those to crypto/include/internal and adapt the affected source code and Makefiles.

* memset, memcpy, sizeof consistency fixesRich Salz2015-05-051-2/+2
| | | | | | | | Just as with the OPENSSL_malloc calls, consistently use sizeof(*ptr) for memset and memcpy. Remove needless casts for those functions. For memset, replace alternative forms of zero with 0. Reviewed-by: Richard Levitte <levitte@openssl.org>
* Use safer sizeof variant in mallocRich Salz2015-05-041-4/+4
| | | | | | | | | | | | | For a local variable: TYPE *p; Allocations like this are "risky": p = OPENSSL_malloc(sizeof(TYPE)); if the type of p changes, and the malloc call isn't updated, you could get memory corruption. Instead do this: p = OPENSSL_malloc(sizeof(*p)); Also fixed a few memset() calls that I noticed while doing this. Reviewed-by: Richard Levitte <levitte@openssl.org>

| | | | | | | | | | | | | distinction (which does not work well because if CRYPTO_MDEBUG is defined at library compile time, it is not necessarily defined at application compile time; and memory debugging now can be reconfigured at run-time anyway). To get the intended semantics, we could just use the EVP_DigestInit_dbg unconditionally (which uses the caller's __FILE__ and __LINE__ for memory leak debugging), but this would make memory debugging inconsistent. Instead, callers can use CRYPTO_push_info() to track down memory leaks. Also fix indentation, and add OpenSSL copyright.
