SSL_CTX_SET_QUIET_SHUTDOWN(3)OpenSSLSSL_CTX_SET_QUIET_SHUTDOWN(3)
SSL_CTX_set_quiet_shutdown, SSL_CTX_get_quiet_shutdown,
SSL_set_quiet_shutdown, SSL_get_quiet_shutdown - manipulate
shutdown behaviour
#include <openssl/ssl.h>
void SSL_CTX_set_quiet_shutdown(SSL_CTX *ctx, int mode);
int SSL_CTX_get_quiet_shutdown(const SSL_CTX *ctx);
void SSL_set_quiet_shutdown(SSL *ssl, int mode);
int SSL_get_quiet_shutdown(const SSL *ssl);
SSL_CTX_set_quiet_shutdown() sets the "quiet shutdown" flag
for ctx to be mode. SSL objects created from ctx inherit the
mode valid at the time SSL_new(3) is called. mode may be 0
or 1.
SSL_CTX_get_quiet_shutdown() returns the "quiet shutdown"
setting of ctx.
SSL_set_quiet_shutdown() sets the "quiet shutdown" flag for
ssl to be mode. The setting stays valid until ssl is removed
with SSL_free(3) or SSL_set_quiet_shutdown() is called
again. It is not changed when SSL_clear(3) is called. mode
may be 0 or 1.
SSL_get_quiet_shutdown() returns the "quiet shutdown" set-
ting of ssl.
Normally when a SSL connection is finished, the parties must
send out "close notify" alert messages using SSL_shutdown(3)
for a clean shutdown.
When setting the "quiet shutdown" flag to 1, SSL_shutdown(3)
will set the internal flags to
SSL_SENT_SHUTDOWN|SSL_RECEIVED_SHUTDOWN. (SSL_shutdown(3)
then behaves like SSL_set_shutdown(3) called with
SSL_SENT_SHUTDOWN|SSL_RECEIVED_SHUTDOWN.) The session is
thus considered to be shutdown, but no "close notify" alert
is sent to the peer. This behaviour violates the TLS stan-
dard.
The default is normal shutdown behaviour as described by the
TLS standard.
SSL_CTX_set_quiet_shutdown() and SSL_set_quiet_shutdown() do
not return diagnostic information.
