Need some help about SSL_shutdown()

[Priyaranjan Nayak]

Hi All,


 I am using openssl-1.0.1c in our project.when SSL_shutdown(ssl) get
executed it returns 0.If I get return value zero then calling  the same
SSL_shutdown(ssl) again.In 2nd time it return -1/SSL_ERROR_WANT_READ. Now I
am doing SSL_read(), but it returns -1.Again I am calling SSL_shutdown(ssl)
and it returns -1/SSL_ERROR_WANT_READ.How can I execute SSL_shutdown(ssl),
so that it will return 1. Code snippet given below

while(1)
{
status = SSL_shutdown(ssl);
if(status == 1)
{
   printf(ssl_shutdown() successfull);
}
else if(status == 0)
{
  printf(ssl_shutdown() client  successfull);
}
else
{
  err = SSL_get_error(ssl, status);
switch (err)
{
case SSL_ERROR_WANT_READ:
length = SSL_read(ssl,buf,size);//returns -1
printf(ERROR: ssl SSL_ERROR_WANT_READ : %d,length);
break;
}
  if(status == 1)
 break;

}

O/p:
ssl_shutdown() client  successfull
ERROR: ssl SSL_ERROR_WANT_READ : -1
ERROR: ssl SSL_ERROR_WANT_READ : -1
ERROR: ssl SSL_ERROR_WANT_READ : -1
.
.
.

Please suggest me how to do ssl_shutdown().
Thanks

Crashing at BIO_free_all() in openssl

[Priyaranjan Nayak]

Hi All,

 I am using openssl-1.0.1c in our project as DTLS . I am trying to
delete all memory of SSL, SSL_CTX and BIO. But  it is crashing at
BIO_free_all() in openssl's lib.
1. Is there any procedure to followup to free these memories  ?
2. If I free SSL and SSL_CTX, will it free the BIO implicitly or I need to
free BIO explicitly ?


Thanks

 Did you run ms\do_ms.bat in between the configure and the nmake command?**
