* Ensure all locks are properly cleaned upMatt Caswell2016-04-141-3/+7
| | | | | | Some locks were not being properly cleaned up during close down. Reviewed-by: Richard Levitte <levitte@openssl.org>
* Remove check_defer()Dr. Stephen Henson2016-04-131-1/+3
| | | | | | | | | | | The check_defer() function was used to ensure that EVP_cleanup() was always called before OBJ_cleanup(). The new cleanup code ensures this so it is no longer needed. Remove obj_cleanup() call in OID config module: it is not needed any more either. Reviewed-by: Matt Caswell <matt@openssl.org>

* Rename int_*() functions to *_int()Matt Caswell2016-04-131-48/+48
| | | | | | | | | | There is a preference for suffixes to indicate that a function is internal rather than prefixes. Note: the suffix is only required to disambiguate internal functions and public symbols with the same name (but different case) Reviewed-by: Tim Hudson <tjh@openssl.org> Reviewed-by: Richard Levitte <levitte@openssl.org>

* Remove some OPENSSL_NO_ASYNC guards in initMatt Caswell2016-04-061-8/+1
| | | | | | | | When config'd with "no-async" the ASYNC_NULL implementation is used, so async symbols still exist. We should still init the NULL implementation so that when we get the async ctx it is NULL rather than undefined. Reviewed-by: Rich Salz <rsalz@openssl.org>

* Add some missing cleanup calls to de-initMatt Caswell2016-03-141-0/+2
| | | | | | | | OBJ_cleanup() doesn't always get called from EVP_cleanup() so needs to be explicitly called in de-init. Also BIO_sock_cleanup() also needs to be called. Reviewed-by: Richard Levitte <levitte@openssl.org>
* Fix memory leak in library deinitEmilia Kasper2016-03-121-5/+8
| | | | | | | | | | | | | | ENGINE_cleanup calls CRYPTO_free_ex_data and therefore, CRYPTO_cleanup_all_ex_data - which cleans up the method pointers - must run after ENGINE_cleanup. Additionally, don't needlessly initialize the EX_CALLBACKS stack during e.g. CRYPTO_free_ex_data. The only time this is actually needed is when reserving the first ex data index. Specifically, since sk_num returns -1 on NULL input, the rest of the code already handles a NULL method stack correctly. Reviewed-by: Rich Salz <rsalz@openssl.org>

* Call CONF_modules_free() before ENGINE_cleanup() in auto-deinitMatt Caswell2016-03-111-3/+3
| | | | | | | | | | During auto de-init we were calling ENGINE_cleanup(), and then later CONF_modules_free(). However the latter function can end up calling engine code, which can lead to a use of the global_engine_lock after it has already been freed. Therefore we should swap the calling order of these two functions. Reviewed-by: Rich Salz <rsalz@openssl.org>

| | | | | | | | | | | | | | | | | | | | | When OPENSSL_NO_ASYNC is set, make ASYNC_{un,}block_pause() do nothing. This prevents md_rand.c from failing to build.

| | | | | | | | | If init failed we'd like to set an error code to indicate that. But if init failed then when the error system tries to load its strings its going to fail again.
