Unlike retrieving TCP statistics with the GetPerTcpConnectionEStats function, retrieving TCP statistics with this control code does not require the user code to load, store, and filter the TCP connection table, and does not require elevated privileges to use. Receive-side scaling (RSS) resolves this issue by allowing the network load from a network adapter to be balanced across multiple CPUs. Reserved for future use with sockets. To query whether TCP keep-alive is enabled on a socket, the getsockopt function can be called with the SO_KEEPALIVE option. These include the Winsock2.h, Mswsock.h, and Mstcpip.h header file. The Internet Security and Acceleration (ISA) server is an example of such an edge device. The WSAENOPROTOOPT error code is indicated for service providers that do not support this IOCTL. Once the socket is bound and the IOCTL set, calls to the WSARecv or recv functions return multicast IP datagrams passing through the given interface. On a LAN segment with a network hub, a NIC that supports promiscuous mode will capture all IPv4 or IPv6 traffic on the LAN, including traffic between other computers on the same LAN segment. No output buffer is required, the QOS structure will be obtained from the input buffer. Sr. 3 The IOCTL applies only to a specific vendor's provider, as with IOC_VENDOR. First, this doesn't help the project at all, you've placed a bandaid over a … The WSAAsyncSelect or WSAEventSelect routine automatically sets a socket to non-blocking mode. The list of addresses varies based on address family and some addresses are excluded from the list. The input buffer is a processor index (0-based) of type USHORT. To receive notification of a routing interface change that should be used to reach the remote address in the input buffer (specified as a sockaddr structure). The pointer to the desired function is returned in the output buffer. The input buffer contains a globally unique identifier (GUID) whose value identifies the extension function in question. SIO_LOOPBACK_FAST_PATH is supported on Windows 8, Windows Server 2012, and later. lpcbBytesReturned A pointer to actual number of bytes of output. make[3]: *** [dovlc] Error 1 For more detailed information, see the SIO_TCP_INITIAL_RTO reference. The dwIoControlCode parameter has the following form. I'm unable to find a solution for this problem, and would very much appreciate any help anyone might be willing to offer. The WSAENOPROTOOPT error code is indicated for service providers that do not support quality of service. lpOverlapped A pointer to aWSAOVERLAPPEDstructure (ignored for non-overlapped sockets). It contains both Universal Windows Driver and desktop-only driver samples. The runtime reservation to be released must have been obtained from the issuing process using the SIO_ACQUIRE_PORT_RESERVATION IOCTL. No input and output buffers are required. For more detailed information, see the SIO_RELEASE_PORT_RESERVATION reference. So the left-most bit is bit 31, the next bit is bit 30, and the right-most bit is bit 0. Determine whether or not all OOB data has been read. After all those steps, I finally got an executable binary file. Updating the pca10056 target to use the block device for VFS/FATFS. The ISB value per connection is available from the TCP protocol implementation in Windows Server 2008 and later. If the socket passed in the s parameter is stream oriented (for example, type SOCK_STREAM), FIONREAD returns the total amount of data that can be read in a single receive operation; this is normally the same as the total amount of data queued on the socket (since a data stream is byte-oriented, this is not guaranteed). The QOS structure will be copied into the output buffer. If the output buffer is not large enough for a socket handle (the cbOutBuffer is less than the size of a SOCKET) or the lpvOutBuffer parameter is a NULL pointer, SOCKET_ERROR is returned as the result of this IOCTL and WSAGetLastError returns WSAEFAULT. Therefore, applications cannot rely on the information returned by SIO_ROUTING_INTERFACE_QUERY to be persistent. The WSAENOPROTOOPT error code is indicated for service providers that do not support quality of service. This Ioctl is used by a layered service provider to ensure the provider intercept the WSAPoll function. For more detailed information, see the SIO_KEEPALIVE_VALS reference. The cbOutBuffer parameter specifies the length of the output buffer. By default, SIO_MULTIPOINT_LOOPBACK is enabled. additional flags are The input buffer is optional. SIO_GET_INTERFACE_LIST is supported on Windows Me/98 and Windows NT 4.0 with SP4 and later. The following sequence of actions can be used to guarantee that the application always has current routing interface information for a given destination: If the output buffer is not large enough to contain the interface address, SOCKET_ERROR is returned as the result of this IOCTL and WSAGetLastError returns WSAEFAULT. Queries the redirect record for the accepted TCP/IP connection for use by a Windows Filtering Platform (WFP) redirect service. Queries the redirect context for a redirect record used by a Windows Filtering Platform (WFP) redirect service. The console output The ISB value is a function of the bandwidth-delay product of the TCP connection and the receiver's advertised receive window (and partly the amount of congestion in the network). The socket handle passed to the WSAIoctl function must be one of the following: The socket also must be bound to an explicit local IPv4 or IPv6 interface, which means that you cannot bind to INADDR_ANY or in6addr_any. This IOCTL is not supported for IPv6 sockets and returns the WSAENOPROTOOPT error code. The WSAENOPROTOOPT error code is indicated for service providers that do not support quality of service. A value of FALSE prevents multicast data sent by an application on the local computer from being delivered to a listening socket on the loopback interface. Request a runtime reservation for a block of TCP or UDP ports. ... [lots of successful steps, then ...] ... This IOCTL must be used on both sides of the loopback session. cbInBuffer The size, in bytes, of the input buffer. SIOCSVIPA Defines or deletes an IPv4 dynamic VIPA. To enable or disable TCP keep-alive, the setsockopt function can be called with the SO_KEEPALIVE option. SIO_BSP_HANDLE_POLL is defined in the Mswsock.h header file and supported on Windows Vista and later. SIO_BASE_HANDLE is defined in the Mswsock.h header file and supported on Windows Vista and later. The possible values for the SIO_RCVALL IOCTL option are specified in the RCVALL_VALUE enumeration defined in the Mstcpip.h header file. For more detailed information, see the SIO_QUERY_WFP_CONNECTION_REDIRECT_CONTEXT reference. Associate this socket with the specified handle of a companion interface. For more detailed information, see the SIO_ASSOCIATE_PORT_RESERVATION reference. The required size of the output buffer will be returned in lpcbBytesReturned in this case. Discards current contents of the sending queue associated with this socket. This situation can be avoided by extending the meaning of the input parameters and relaxing the service provider requirements as follows: To obtain the address of the local interface (represented as sockaddr structure) which should be used to send to the remote address specified in the input buffer (as sockaddr). For more detailed information, see the SIO_LOOPBACK_FAST_PATH reference. (The sa_family subfield should be consulted to determine the format of the address structure.) Requests how the networking stack should handle certain behaviors for which the default way of handling the behavior may differ across Windows versions. Use the WSAIoctl or WSPIoctl function to issue a Winsock IOCTL to control the mode of a socket, the transport protocol, or the communications subsystem. SIO_RCVALL_MCAST is supported on Windows 2000 and later. The following Windows Sockets 2 commands are supported. This applies only to a socket of stream-style (for example, type SOCK_STREAM) that has been configured for inline reception of any OOB data (SO_OOBINLINE). Retrieves information about QoS traffic characteristics. on linux my patch increases the sizes of dynamic libraries by less than 1%: lib-linux.so: 138882 --> 139965 lib-rawsock.so: 265699 --> 266758. Retrieve a pointer to the specified extension function supported by the associated service provider. Enable or disable non-blocking mode on socket s. The lpvInBuffer parameter points at an unsigned long (QoS), which is nonzero if non-blocking mode is to be enabled and zero if it is to be disabled. Macros and defines specifying V4L2 ioctl requests are located in the videodev.h header file. SIO_KEEPALIVE_VALS is supported on Windows 2000 and later. The lpOverlapped parameter must be a NULL pointer. The handle associated by this IOCTL can be retrieved using SIO_TRANSLATE_HANDLE. Retrieves the base service provider handle for a socket used by the WSASendMsg function.
