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>

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.

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>

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.

Stop init loops Under certain circumstances, the libcrypto init code would loop, causing a deadlock. This would typically happen if something in ossl_init_base() caused an OpenSSL error, and the error stack routines would recurse into the init code before the flag that ossl_init_base() had been run was checked. This change makes sure ossl_init_base isn't run once more of the base is initiated. Thanks to Dmitry Kostjuchenko for the idea.

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.

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.

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>
