Because symbols are known to disappear, and signatures sometimes change, between releases, we need to be careful about how this is done. To ensure we don't end up dereferencing null function pointers, and continue running even if certain functions are missing, we define helper functions for each of the symbols we load from OpenSSL, all prefixed with "q_" (declared in qsslsocket_openssl_symbols_p.h). So instead of calling SSL_connect directly, we call q_SSL_connect, which is a function that checks if the actual SSL_connect fptr is null, and returns a failure if it is, or calls SSL_connect if it isn't. This requires a somewhat tedious process of declaring each function we want to call in OpenSSL thrice: once with the q_, in _p.h, once using the DEFINEFUNC macros below, and once in the function that actually resolves the symbols, below the DEFINEFUNC declarations below. There's one DEFINEFUNC macro declared for every number of arguments exposed by OpenSSL (feel free to extend when needed). The easiest thing to do is to find an existing entry that matches the arg count of the function you want to import, and do the same. The first macro arg is the function return type. The second is the verbatim name of the function/symbol. Then follows a list of N pairs of argument types with a variable name, and just the variable name (char *a, a, char *b, b, etc). Finally there's two arguments - a suitable return statement for the error case (for an int function, return 0 or return -1 is usually right). Then either just "return" or DUMMYARG, the latter being for void functions. Note: Take into account that these macros and declarations are processed at compile-time, and the result depends on the OpenSSL headers the compiling host has installed, but the symbols are resolved at run-time, possibly with a different version of OpenSSL. */ #ifdef SSLEAY_MACROS DEFINEFUNC3(void *, ASN1_dup, i2d_of_void *a, a, d2i_of_void *b, b, char *c, c, return 0, return) #endif DEFINEFUNC(long, ASN1_INTEGER_get, ASN1_INTEGER *a, a, return 0, return) DEFINEFUNC(unsigned char *, ASN1_STRING_data, ASN1_STRING *a, a, return 0, return) DEFINEFUNC(int, ASN1_STRING_length, ASN1_STRING *a, a, return 0, return) DEFINEFUNC2(int, ASN1_STRING_to_UTF8, unsigned char **a, a, ASN1_STRING *b, b, return 0, return); DEFINEFUNC4(long, BIO_ctrl, BIO *a, a, int b, b, long c, c, void *d, d, return -1, return) DEFINEFUNC(int, BIO_free, BIO *a, a, return 0, return) DEFINEFUNC(BIO *, BIO_new, BIO_METHOD *a, a, return 0, return) DEFINEFUNC2(BIO *, BIO_new_mem_buf, void *a, a, int b, b, return 0, return) DEFINEFUNC3(int, BIO_read, BIO *a, a, void *b, b, int c, c, return -1, return) DEFINEFUNC(BIO_METHOD *, BIO_s_mem, void, DUMMYARG, return 0, return) DEFINEFUNC3(int, BIO_write, BIO *a, a, const void *b, b, int c, c, return -1, return) DEFINEFUNC(int, BN_num_bits, const BIGNUM *a, a, return 0, return) DEFINEFUNC(int, CRYPTO_num_locks, DUMMYARG, DUMMYARG, return 0, return) DEFINEFUNC(void, CRYPTO_set_locking_callback, void (*a)(int, int, const char *, int), a, return, DUMMYARG) DEFINEFUNC(void, CRYPTO_set_id_callback, unsigned long (*a)(), a, return, DUMMYARG) DEFINEFUNC(void, CRYPTO_free, void *a, a, return, DUMMYARG) DEFINEFUNC(void, DSA_free, DSA *a, a, return, DUMMYARG) #if OPENSSL_VERSION_NUMBER < 0x00908000L DEFINEFUNC3(X509 *, d2i_X509, X509 **a, a, unsigned char **b, b, long c, c, return 0, return) #else // 0.9.8 broke SC and BC by changing this signature.
