Hello,
I have a code cross compiled to 2 devices. On 1 device the code works
flawlessly, on the other SSL_connect does nothing. Info about both devices:
Device 1: (working)
CPU: PowerPC @ 220MHz
RAM: 128MB SD-RAM
Device 2: (not working)
CPU: PowerPC @ 133MHz
RAM:32MB SD-RAM
here's the code I'm using after sending EHLO and STARTTLS:
*
static SSL_CTX *ctx = NULL;
static SSL *ssl = NULL;
void CreateTLSSession(int sockfd)
{
int RetValue=0;
printf("CREATING TLS SESSION...\n");
SSL_library_init();
SSL_load_error_strings();
OpenSSL_add_all_algorithms();
//ctx = SSL_CTX_new(TLSv1_client_method());
ctx = SSL_CTX_new(TLSv1_client_method());
//(SSL_CTX_set_options(ctx, SSL_OP_NO_COMPRESSION);
//SSL_CTX_set_mode(ctx, SSL_MODE_RELEASE_BUFFERS);
if (ctx == NULL)
{
printf("failed to initialize context\n");
return;
}
printf("CTX created...\n");
ssl = SSL_new(ctx);
if (ssl == NULL)
{
printf("failed to create SSL structure...\n");
return;
}
if (!SSL_set_fd(ssl, sockfd))
{
printf("failed to bind to socket fd\n");
return;
}
printf("SSL bound to sockfd=%d...\n",sockfd);
while (RetValue != 1)
{
perror("SSL_connect");
sleep(1);
RetValue = SSL_connect(ssl);
}
printf("OK\n");
}*
The socket is non-blocking. I'm using a while loop for test purposes. The
loop will be substituted by "switch" later on.
The code output the following:
*CREATING TLS SESSION...
CTX created...
SSL bound to sockfd=9...
SSL_connect: No such file or directory
SSL_connect: Success
SSL_connect: Success
SSL_connect: Success
SSL_connect: Success
SSL_connect: Success
SSL_connect: Success
SSL_connect: Success
SSL_connect: Success
SSL_connect: Success*
but never gets out of the loop.
I managed to connect device 2 to a managed switch and observe the network
traffic through wireshark. To my surprise, SSL_connect() has no effect. The
last thing shown by wireshark is "220 2.0.0 Ready to start TLS".
I've attached a the .pcap file to this post.
Any help will be greatly appreciated.
