Hello,
I am developing an client application using OpenSSL C API. I have an
error in the this code:
/* connection struct consists of SSL_CTX, SSL and BIO pointers */
...
connection->ctx = SSL_CTX_new(SSLv23_client_method());
if (connection->ctx == NULL)
{
DEBUG_MESSAGE("SSL_CTX_new failed\n");
DEBUG(ERR_print_errors_fp(stdout));
return NULL;
}
if (!SSL_CTX_load_verify_locations(connection->ctx, NULL,
"../share/xclient/certificates/"))
{
DEBUG_MESSAGE("SSL_CTX_load_verify_locations failed\n");
DEBUG(ERR_print_errors_fp(stdout));
return NULL;
}
connection->bio = BIO_new_ssl_connect(connection->ctx);
if (connection->bio == NULL)
{
DEBUG_MESSAGE("BIO_new_ssl_connect failed\n");
DEBUG(ERR_print_errors_fp(stdout));
return NULL;
}
BIO_get_ssl(connection->bio, &connection->ssl);
if (connection->ssl == NULL);
{
DEBUG_MESSAGE("BIO_get_ssl failed\n");
DEBUG(ERR_print_errors_fp(stdout));
return NULL;
}
SSL_set_mode(connection->ssl, SSL_MODE_AUTO_RETRY);
BIO_set_conn_hostname(connection->bio,
xapi_get_dsnp_server_name(xapi_get_http_server_name(uri)));
if (BIO_do_connect(connection->bio) < 1)
{
DEBUG_MESSAGE("BIO_do_connect failed\n");
DEBUG(ERR_print_errors_fp(stdout));
return NULL;
}
if (SSL_get_verify_result(connection->ssl) != X509_V_OK)
{
DEBUG_MESSAGE("SSL_get_verify_result failed\n");
DEBUG(ERR_print_errors_fp(stdout));
return NULL;
}
...
After BIO_get_ssl function call SSL pointer is NULL. If I comment out the
return from the function after this error, BIO_do_connect fails with message:
3078686456:error:0200206F:system library:connect:Connection
refused:bss_conn.c:269:host=localhost:33500
3078686456:error:20073067:BIO routines:CONN_STATE:connect error:bss_conn.c:273:
This is my makefile:
CC = gcc
TARGET = ../../bin/xtool
CFLAGS = -Wall -std=ansi -D_REENTERANT -DXCOMMON_DEBUG -I../
-I/usr/include/glib-1.2 -I/usr/lib/glib/include
LIBS = -lcurl -lglib -lcrypto -lssl
SOURCES = main.c\
../xapi/api.c
all:
$(CC) -o $(TARGET) $(CFLAGS) $(LIBS) $(SOURCES)
What I am doing wrong?
Sincerely, Kyrylo.
