SYNOPSIS
Header "SYNOPSIS" .Vb 1
#include <openssl/ssl.h>
\&
#define SSL_INCOMING_STREAM_POLICY_AUTO
#define SSL_INCOMING_STREAM_POLICY_ACCEPT
#define SSL_INCOMING_STREAM_POLICY_REJECT
\&
int SSL_set_incoming_stream_policy(SSL *conn, int policy,
uint64_t app_error_code);

DESCRIPTION
Header "DESCRIPTION" \fBSSL_set_incoming_stream_policy() policy changes the incoming stream policy for a
QUIC connection. Depending on the policy configured, OpenSSL QUIC may
automatically reject incoming streams initiated by the peer. This is intended to
ensure that legacy applications using single-stream operation with a default
stream on a QUIC connection SSL object are not passed remotely-initiated streams
by a peer which those applications are not prepared to handle.
\fIapp_error_code is an application error code which will be used in any QUIC \fBSTOP_SENDING or RESET_STREAM frames generated to implement the policy. The default application error code is 0.
The valid values for policy are:
SSL_INCOMING_STREAM_POLICY_AUTO 4
Item "SSL_INCOMING_STREAM_POLICY_AUTO" This is the default setting. Incoming streams are accepted according to the
following rules:
\(bu 4
If the default stream mode (configured using SSL_set_default_stream_mode\|(3))
is set to SSL_DEFAULT_STREAM_MODE_AUTO_BIDI (the default) or
\fBSSL_DEFAULT_STREAM_MODE_AUTO_UNI, the incoming stream is rejected.
\(bu 4
Otherwise (where the default stream mode is SSL_DEFAULT_STREAM_MODE_NONE),
the application is assumed to be stream aware, and the incoming stream is
accepted.
SSL_INCOMING_STREAM_POLICY_ACCEPT 4
Item "SSL_INCOMING_STREAM_POLICY_ACCEPT" Always accept incoming streams, allowing them to be dequeued using
\fBSSL_accept_stream\|(3).
SSL_INCOMING_STREAM_POLICY_REJECT 4
Item "SSL_INCOMING_STREAM_POLICY_REJECT" Always reject incoming streams.
Where an incoming stream is rejected, it is rejected immediately and it is not possible to gain access to the stream using SSL_accept_stream\|(3). The stream is rejected using QUIC STOP_SENDING and RESET_STREAM frames as appropriate.
"RETURN VALUES"
Header "RETURN VALUES" Returns 1 on success and 0 on failure.
This function fails if called on a QUIC stream SSL object, or on a non-QUIC SSL object.
"SEE ALSO"
Header "SEE ALSO" \fBSSL_set_default_stream_mode\|(3), SSL_accept_stream\|(3)
HISTORY
Header "HISTORY" \fBSSL_set_incoming_stream_policy() was added in OpenSSL 3.2.
