Hi All,
Can anyone suggest me for the following error urgently.
I am using the stunnel source using threads for servicing the clients.
Some time for more than one client it does the correct data transfer.
But at some times when first thread closes, and the second thread is on the
verge of handshaking with SSL_accept, the second thread also closes off.
Why is this so. Is there anything else to be done apart from below.
I am getting following error:
LOG7[4266:12]: SSL closed on read (DMZ Server)
LOG5[4266:12]: Connection closed: 42 bytes recieved from Client, 6 bytes
sent to Client
LOG7[4266:12]: client thread finished (1 left)
LOG7[4266:13]: before/accept initialization
LOG7[4266:13]: before/accept initialization
LOG7[4266:11]: SSL closed on read (DMZ Server)
LOG5[4266:11]: Connection closed: 42 bytes recieved from Client, 6 bytes
sent to Client
LOG7[4266:13]: SSLv3 read client hello B
LOG7[4266:13]: SSLv3 read client hello B
LOG3[4266:13]: SSL_accept dmz: error:00000000::lib(0) :func(0) :reason(0)
LOG7[4266:13]: client thread finished (1 left)
LOG7[4266:11]: client thread finished (0 left)
when it was accepting for thread 13, the thread 12 has closed and it closes
off the thread 13.
I have done the locking as below:
static void locking_callback(int mode, int type,
#ifdef HAVE_OPENSSL
const /* Callback definition has been changed in openssl 0.9.3 */
#endif
char *file, int line)
{
if(mode&CRYPTO_LOCK){
pthread_mutex_lock(lock_cs+type);
printf("Locking thread\n");
} else {
pthread_mutex_unlock(lock_cs+type);
printf("UNLocking thread\n");
}
}
void sthreads_init()
{
int i;
for(i=0; i<CRYPTO_NUM_LOCKS; i++)
pthread_mutex_init(lock_cs+i, NULL);
CRYPTO_set_id_callback(thread_id);
CRYPTO_set_locking_callback(locking_callback);
pthread_attr_init(&pth_attr);
pthread_attr_setdetachstate(&pth_attr, PTHREAD_CREATE_DETACHED);
}
unsigned long process_id()
{
return (unsigned long)getpid();
}
unsigned long thread_id()
{
return (unsigned long)pthread_self();
}
Thanks in advance.
