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>

RT4310: Fix varous no-XXX builds When OPENSSL_NO_ASYNC is set, make ASYNC_{un,}block_pause() do nothing. This prevents md_rand.c from failing to build. Probably better to do it this way than to wrap every instance in an explicit #ifdef. A bunch of new socket code got added to a new file crypto/bio/b_addr.c. Make it all go away if OPENSSL_NO_SOCK is defined. Allow configuration with no-ripemd, no-ts, no-ui We use these for the UEFI build. Also remove the 'Really???' comment from no-err and no-locking. We use those too. We need to drop the crypto/engine directory from the build too, and also set OPENSSL_NO_ENGINE Signed-off-by: Rich Salz <rsalz@openssl.org> Reviewed-by: Tim Hudson <tjh@openssl.org>

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>

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>

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>

Rework based on feedback: 1. Cleaned up eventfd handling 2. Reworked socket setup code to allow other algorithms to be added in future 3. Fixed compile errors for static build 4. Added error to error stack in all cases of ALG_PERR/ALG_ERR 5. Called afalg_aes_128_cbc() from bind() to avoid race conditions 6. Used MAX_INFLIGHT define in io_getevents system call 7.

Swap the init code to use CRYPTO_ONCE The init code was using its own "once" implementation. Now that we have the new thread API we should use that instead. Reviewed-by: Richard Levitte <levitte@openssl.org>

The new init functions can now fail so shouldn't be void The new init functions can fail if the library has already been stopped. We should be able to indicate failure with a 0 return value. Reviewed-by: Rich Salz <rsalz@openssl.org>
