Hi,
I have an SSL server that runs fine on Windows and on Linux. However
on Solaris and IBM platforms, if the client is a windows one, my
server crashes when the client exits.
I was able to track the crash to the second call of SSL_shutdown below
in my server code:
r=SSL_shutdown(ssl);
if(!r){
shutdown(s,1);
r=SSL_shutdown(ssl);
}
Anyone knows why would SSL_shutdown crash?
The OpenSSL documentation says this about the return value of SSL_shutdown:
*0*
The shutdown is not yet finished. Call SSL_shutdown() for a second time, if
a bidirectional shutdown shall be performed. The output of
SSL_get_error(3)<http://www.openssl.org/docs/ssl/SSL_get_error.html#>may
be misleading, as an erroneous SSL_ERROR_SYSCALL may be flagged even
though no error occurred.
I did verify that at the crash time, the returned value is 0. Once the
second SSL_shutdown is called then the server is dead.
If the client is anything other than a windows client, then this
problem does not occur!!...
I am using :
openssl-0.9.8e
Thanks for any help.
