* Fix BIO_pop for SSL BIOsMatt Caswell2016-07-291-10/+2
| | | | | | | | | | | | | | | The BIO_pop implementation assumes that the rbio still equals the next BIO in the chain. While this would normally be the case, it is possible that it could have been changed directly by the application. It also does not properly cater for the scenario where the buffering BIO is still in place for the write BIO. Most of the existing BIO_pop code for SSL BIOs can be replaced by a single call to SSL_set_bio(). This is equivalent to the existing code but additionally handles the scenario where the rbio has been changed or the buffering BIO is still in place. Reviewed-by: Rich Salz <rsalz@openssl.org>
* Fix BIO_push ref counting for SSL BIOMatt Caswell2016-07-291-1/+5
| | | | | | | | | When pushing a BIO onto an SSL BIO we set the rbio and wbio for the SSL object to be the BIO that has been pushed. Therefore we need to up the ref count for that BIO. The existing code was uping the ref count on the wrong BIO. Reviewed-by: Rich Salz <rsalz@openssl.org>

* Add and use OPENSSL_zallocRich Salz2015-09-021-2/+1
| | | | | | | | | There are many places (nearly 50) where we malloc and then memset. Add an OPENSSL_zalloc routine to encapsulate that. (Missed one conversion; thanks Richard) Also fixes GH328 Reviewed-by: Richard Levitte <levitte@openssl.org>
* memset, memcpy, sizeof consistency fixesRich Salz2015-05-051-1/+1
| | | | | | | | 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 Salz2015-05-041-2/+1
| | | | | | | | | | | | | 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>

* Resolve swallowed returns codesMatt Caswell2015-03-251-1/+2
| | | | | | | | | | The recent updates to libssl to enforce stricter return code checking, left a small number of instances behind where return codes were being swallowed (typically because the function they were being called from was declared as void).

* Fixes for Win32 build.Dr. Stephen Henson2000-06-211-2/+2
| | | | | | | | | | | | | | | | | This is mostly a work around for the old VC++ problem that it treats func() as func(void). Various prototypes had been added to 'compare' function pointers that triggered this. This could be fixed by removing the prototype, adding function pointer casts to every call or changing the passed function to use the expected arguments. I mostly did the latter. The mkdef.pl script was modified to remove the typesafe functions which no longer exist. Oh and some functions called OPENSSL_freeLibrary() were changed back to FreeLibrary(), wonder how that happened :-)
* There have been a number of complaints from a number of sources that namesRichard Levitte2000-06-011-2/+2
| | | | | | | | | like Malloc, Realloc and especially Free conflict with already existing names on some operating systems or other packages. That is reason enough to change the names of the OpenSSL memory allocation macros to something that has a better chance of being unique, like prepending them with OPENSSL_. This change includes all the name changes needed throughout all C files.

Please note that I'm a little unsure how incorrect calls to the old ctrl functions should be handled, in som cases. I currently return 0 and that's it, but it may be more correct to generate a genuine error in those cases.
* Compaq C 6.2 for VMS will complain when we want to convertRichard Levitte2000-01-181-1/+12
| | | | | | | | | | non-function pointers to function pointers and vice versa. The current solution is to have unions that describe the conversion we want to do, and gives us the ability to extract the type of data we want. The current solution is a quick fix, and can probably be made in a more general or elegant way.
