#include "internal/cryptlib.h"
Reorganize private crypto header files Currently, there are two different directories which contain internal header files of libcrypto which are meant to be shared internally: While header files in 'include/internal' are intended to be shared between libcrypto and libssl, the files in 'crypto/include/internal' are intended to be shared inside libcrypto only. To make things complicated, the include search path is set up in such a way that the directive #include "internal/file.h" could refer to a file in either of these two directoroes. This makes it necessary in some cases to add a '_int.h' suffix to some files to resolve this ambiguity: #include "internal/file.h" # located in 'include/internal' #include "internal/file_int.h" # located in 'crypto/include/internal' This commit moves the private crypto headers from 'crypto/include/internal' to 'include/crypto' As a result, the include directives become unambiguous #include "internal/file.h" # located in 'include/internal' #include "crypto/file.h" # located in 'include/crypto' hence the superfluous '_int.h' suffixes can be stripped. The files 'store_int.h' and 'store.h' need to be treated specially; they are joined into a single file.

s390x: Hide internal cpuid symbol and function The symbol OPENSSL_s390xcap_P and the OPENSSL_cpuid_setup function are not exported by the version script of OpenSSL. However, if someone uses the static library without the version script, these symbols all of a sudden become global symbols and their usage in assembler code does not correctly reflect that for PIC. Since these symbols should never be used outside of OpenSSL, hide them inside the binary.

S390x: Support ME and CRT offloading S390x has to ability to offload modular exponentiation and CRT operations to Crypto Express Adapters. This possible performance optimization was not yet used by OpenSSL. Add support for offloading and implement an optimized version of RSA and DH with it. The environment variable OPENSSL_s390xcap now recognizes the token "nocex" to prevent offloading.
