Provide framework for auto initialise/deinitialise of the library This commit provides the basis and core code for an auto initialisation and deinitialisation framework for libcrypto and libssl. The intention is to remove the need (in many circumstances) to call explicit initialise and deinitialise functions. Explicit initialisation will still be an option, and if non-default initialisation is needed then it will be required. Similarly for de-initialisation (although this will be a lot easier since it will bring all de-initialisation into a single function). Reviewed-by: Richard Levitte <levitte@openssl.org>

crypto/init.c: use destructor_key even as guard in OPENSSL_thread_stop. Problem was that Windows threads that were terminating before libcrypto was initialized were referencing uninitialized or possibly even unrelated thread local storage index.

/*
* Since per-thread-specific-data destructors are not universally
* available, i.e. not on Windows, only below CRYPTO_THREAD_LOCAL key
* is assumed to have destructor associated. And then an effort is made
* to call this single destructor on non-pthread platform[s].
*
* Initial value is "impossible". It is used as guard value to shortcut
* destructor for threads terminating before libcrypto is initialized or
* after it's de-initialized. Access to the key doesn't have to be
* serialized for the said threads, because they didn't use libcrypto
* and it doesn't matter if they pick "impossible" or derefernce real
* key value and pull NULL past initialization in the first thread that
* intends to use libcrypto.

fprintf(stderr, "OPENSSL_INIT: ossl_init_base: Setting up stop handlers\n");
Add "random malloc failure" tooling 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.

Ensure that libcrypto and libssl do not unload until the process exits Because we use atexit() to cleanup after ourselves, this will cause a problem if we have been dynamically loaded and then unloaded again: the atexit() handler may no longer be there. Most modern atexit() implementations can handle this, however there are still difficulties if libssl gets unloaded before libcrypto, because of the atexit() callback that libcrypto makes to libssl. The most robust solution seems to be to ensure that libcrypto and libssl never unload. This is done by simply deliberately leaking a dlopen() reference to them.

Add dladdr() for AIX Although it deviates from the actual prototype of DSO_dsobyaddr(), this is now ISO C compliant and gcc -Wpedantic accepts the code. Added DATA segment checking to catch ptrgl virtual addresses. Avoid memleaks with every AIX/dladdr() call. Removed debug-fprintf()s. Added test case for DSO_dsobyaddr(), which will eventually call dladdr(). Removed unecessary AIX ifdefs again. The implementation can only lookup function symbols, no data symbols. Added PIC-flag to aix*-cc build targets. As AIX is missing a dladdr() implementation it is currently uncertain our exit()-handlers can still be called when the application exits.

CRYPTO_THREAD_lock_free(init_lock);
Restore clearing of init_lock after free The behavior of resetting the init_lock value to NULL after freeing it during OPENSSL_cleanup() was added as part of the global lock commits that were just reverted, but there is desire to retain this behavior for clarity. It is unclear that the library would actually remain usable in any form after OPENSSL_cleanup(), since the required re-initialization occurs under a CRYPTO_ONCE check that cannot be reset at cleanup time. That said, a NULL dereference is probably more friendly behavior in these treacherous waters than using freed memory would be.

rand_cleanup_int();
Fix reseeding issues of the public RAND_DRBG Reseeding is handled very differently by the classic RAND_METHOD API and the new RAND_DRBG api. These differences led to some problems when the new RAND_DRBG was made the default OpenSSL RNG. In particular, RAND_add() did not work as expected anymore. These issues are discussed on the thread '[openssl-dev] Plea for a new public OpenSSL RNG API' and in Pull Request #4328. This commit fixes the mentioned issues, introducing the following changes: - Replace the fixed size RAND_BYTES_BUFFER by a new RAND_POOL API which facilitates collecting entropy by the get_entropy() callback. - Don't use RAND_poll()/RAND_add() for collecting entropy from the get_entropy() callback anymore. Instead, replace RAND_poll() by RAND_POOL_acquire_entropy(). - Add a new function rand_drbg_restart() which tries to get the DRBG in an instantiated state by all means, regardless of the current state (uninstantiated, error, ...) the DRBG is in. If the caller provides entropy or additional input, it will be used for reseeding. - Restore the original documented behaviour of RAND_add() and RAND_poll() (namely to reseed the DRBG immediately) by a new implementation based on rand_drbg_restart(). - Add automatic error recovery from temporary failures of the entropy source to RAND_DRBG_generate() using the rand_drbg_restart() function.

Add the STORE module This STORE module adds the following functionality: - A function OSSL_STORE_open(), OSSL_STORE_load() and OSSL_STORE_close() that accesses a URI and helps loading the supported objects (PKEYs, CERTs and CRLs for the moment) from it. - An opaque type OSSL_STORE_INFO that holds information on each loaded object. - A few functions to retrieve desired data from a OSSL_STORE_INFO reference. - Functions to register and unregister loaders for different URI schemes. This enables dynamic addition of loaders from applications or from engines. Reviewed-by: Matt Caswell <matt@openssl.org> (Merged from https://github.com/openssl/openssl/pull/3542)

OPENSSL_cleanup: cleanup secure memory If the global DRBGs are allocated on the secure heap, then calling CRYPTO_secure_malloc_done() inside main() will have no effect, unless OPENSSL_cleanup() has been called explicitely before that, because otherwise the DRBGs will still be allocated. So it is better to cleanup the secure heap automatically at the end of OPENSSL_cleanup(). Reviewed-by: Rich Salz <rsalz@openssl.org> (Merged from https://github.com/openssl/openssl/pull/5294)

The intention is to remove the need (in many circumstances) to call explicit initialise and deinitialise functions.

Revert the crypto "global lock" implementation Conceptually, this is a squashed version of: Revert "Address feedback" This reverts commit 75551e07bd2339dfea06ef1d31d69929e13a4495. and Revert "Add CRYPTO_thread_glock_new" This reverts commit ed6b2c7938ec6f07b15745d4183afc276e74c6dd. But there were some intervening commits that made neither revert apply cleanly, so instead do it all as one shot. The crypto global locks were an attempt to cope with the awkward POSIX semantics for pthread_atfork(); its documentation (the "RATIONALE" section) indicates that the expected usage is to have the prefork handler lock all "global" locks, and the parent and child handlers release those locks, to ensure that forking happens with a consistent (lock) state. However, the set of functions available in the child process is limited to async-signal-safe functions, and pthread_mutex_unlock() is not on the list of async-signal-safe functions! The only synchronization primitives that are async-signal-safe are the semaphore primitives, which are not really appropriate for general-purpose usage. However, the state consistency problem that the global locks were attempting to solve is not actually a serious problem, particularly for OpenSSL. That is, we can consider four cases of forking application that might use OpenSSL: (1) Single-threaded, does not call into OpenSSL in the child (e.g., the child calls exec() immediately) For this class of process, no locking is needed at all, since there is only ever a single thread of execution and the only reentrancy is due to signal handlers (which are themselves limited to async-signal-safe operation and should not be doing much work at all). (2) Single-threaded, calls into OpenSSL after fork() The application must ensure that it does not fork() with an unexpected lock held (that is, one that would get unlocked in the parent but accidentally remain locked in the child and cause deadlock). Since OpenSSL does not expose any of its internal locks to the application and the application is single-threaded, the OpenSSL internal locks will be unlocked for the fork(), and the state will be consistent. (OpenSSL will need to reseed its PRNG in the child, but that is an orthogonal issue.) If the application makes use of locks from libcrypto, proper handling for those locks is the responsibility of the application, as for any other locking primitive that is available for application programming. (3) Multi-threaded, does not call into OpenSSL after fork() As for (1), the OpenSSL state is only relevant in the parent, so no particular fork()-related handling is needed. The internal locks are relevant, but there is no interaction with the child to consider. (4) Multi-threaded, calls into OpenSSL after fork() This is the case where the pthread_atfork() hooks to ensure that all global locks are in a known state across fork() would come into play, per the above discussion. However, these "calls into OpenSSL after fork()" are still subject to the restriction to async-signal-safe functions. Since OpenSSL uses all sorts of locking and libc functions that are not on the list of safe functions (e.g., malloc()), this case is not currently usable and is unlikely to ever be usable, independently of the locking situation. So, there is no need to go through contortions to attempt to support this case in the one small area of locking interaction with fork(). In light of the above analysis (thanks @davidben and @achernya), go back to the simpler implementation that does not need to distinguish "library-global" locks or to have complicated atfork handling for locks.
