2017-06-28crypto/mem.c: on Windows, use rand() instead of random()Richard Levitte
Windows doesn't provide random(). In this particular case, our requirements on the quality of randomness isn't high, so we don't need to care how good randomness rand() does or doesn't provide.

Reviewed-by: Emilia Käsper <emilia@openssl.org> (Merged from https://github.com/openssl/openssl/pull/2228)
2017-01-12Add "random malloc failure" toolingRich Salz
Still needs to be documented, somehow/somewhere. The env var OPENSSL_MALLOC_FAILURES controls how often malloc/realloc should fail. It's a set of fields separated by semicolons. Each field is a count and optional percentage (separated by @) which defaults to 100. If count is zero then it lasts "forever." For example: 100;@25 means the first 100 allocations pass, then the rest have a 25% chance of failing until the program exits or crashes. If env var OPENSSL_MALLOC_FD parses as a positive integer, a record of all malloc "shouldfail" tests is written to that file descriptor. If a malloc will fail, and OPENSSL_NO_CRYPTO_MDEBUG_BACKTRACE is not set (platform specific), then a backtrace will be written to the descriptor when a malloc fails. This can be useful because a malloc may fail but not be checked, and problems will only occur later.

2016-02-17Implement the use of heap manipulator implementionsRichard Levitte
- Make use of the functions given through CRYPTO_set_mem_functions(). - CRYPTO_free(), CRYPTO_clear_free() and CRYPTO_secure_free() now receive __FILE__ and __LINE__. - The API for CRYPTO_set_mem_functions() and CRYPTO_get_mem_functions() is slightly changed, the implementation for free() now takes a couple of extra arguments, taking __FILE__ and __LINE__. - The CRYPTO_ memory functions will *always* receive __FILE__ and __LINE__ from the corresponding OPENSSL_ macros, regardless of if crypto-mdebug has been enabled or not. The reason is that if someone swaps out the malloc(), realloc() and free() implementations, we can't know if they will use them or not. Reviewed-by: Rich Salz <rsalz@openssl.org>

2016-01-07mem functions cleanupRich Salz
Only two macros CRYPTO_MDEBUG and CRYPTO_MDEBUG_ABORT to control this. If CRYPTO_MDEBUG is not set, #ifdef out the whole debug machinery. (Thanks to Jakob Bohm for the suggestion!) Make the "change wrapper functions" be the only paradigm. Wrote documentation! Format the 'set func' functions so their paramlists are legible. Format some multi-line comments. Remove ability to get/set the "memory debug" functions at runtme. Remove MemCheck_* and CRYPTO_malloc_debug_init macros. Add CRYPTO_mem_debug(int flag) function. Add test/memleaktest. Rename CRYPTO_malloc_init to OPENSSL_malloc_init; remove needless calls. Reviewed-by: Richard Levitte <levitte@openssl.org>
