=head1 NAME
|
|
|
|
SSL_inject_net_dgram - inject a datagram as though received from the network
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
#include <openssl/ssl.h>
|
|
|
|
int SSL_inject_net_dgram(SSL *s, const unsigned char *buf,
|
|
size_t buf_len,
|
|
const BIO_ADDR *peer,
|
|
const BIO_ADDR *local);
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
This function can be used to inject a datagram payload to a QUIC connection SSL
|
|
object. The payload is processed as though it was received from the network.
|
|
This function can be used for debugging purposes or to allow datagrams to be fed
|
|
to QUIC from alternative sources.
|
|
|
|
I<buf> is required and must point to a datagram payload to inject. I<buf_len> is
|
|
the length of the buffer in bytes. The buffer is copied and need not remain
|
|
valid after this function returns.
|
|
|
|
I<peer> and I<local> are optional values pointing to B<BIO_ADDR> structures
|
|
describing the remote and local UDP endpoint addresses for the packet. Though
|
|
the injected packet was not actually received from the network directly by
|
|
OpenSSL, the packet will be processed as though the received datagram had the
|
|
given addresses.
|
|
|
|
=head1 RETURN VALUES
|
|
|
|
Returns 1 on success or 0 on failure. This function always fails if called
|
|
on a SSL object which is not a QUIC connection SSL object.
