Hi,
I’m currently an novice in TDI.
After successful creation a transport-address at \Device\Udp, I got
two troubles:
-
IoCallDriver(TDI_SET_EVENT_HANDLER) for EventType =
TDI_EVENT_CHAINED_RECEIVE_DATAGRAM and TDI_EVENT_RECEIVE_DATAGRAM
returns STATUS_INVALID_ADDRESS (C0000141); -
IoCallDriver(TDI_SEND_DATAGRAM) return STATUS_CANCELLED;
What can be wrong? Incorrect parameters where transport-address
creation, or may be other mistake?
Transport-address creation code is like following:
EaLength = sizeof(FILE_FULL_EA_INFORMATION) +
TDI_TRANSPORT_ADDRESS_LENGTH + sizeof(TA_IP_ADDRESS);
RtlZeroMemory(pEaBuffer, EaLength);
pEaBuffer->EaNameLength = TDI_TRANSPORT_ADDRESS_LENGTH;
RtlCopyMemory(pEaBuffer->EaName, TdiTransportAddress, TDI_TRANSPORT_ADDRESS_LENGTH);
TA_IP_ADDRESS *Ip4 = (TA_IP_ADDRESS *) (pEaBuffer->EaName + TDI_TRANSPORT_ADDRESS_LENGTH + 1);
Ip4->TAAddressCount = 1;
pEaBuffer->EaValueLength = sizeof(TA_IP_ADDRESS);
Ip4->Address[0].AddressLength = TDI_ADDRESS_LENGTH_IP;
Ip4->Address[0].AddressType = TDI_ADDRESS_TYPE_IP;
Ip4->Address[0].Address[0].sin_port = UDP_PORT_NETWORK_ORDER;
Ip4->Address[0].Address[0].in_addr = IPv4_ADDRESS_NETWORK_ORDER;
RtlInitUnicodeString(&TransportDeviceObjectName, L"\Device\Udp");
InitializeObjectAttributes(&ObjectAttributes, &TransportDeviceObjectName,
OBJ_CASE_INSENSITIVE | OBJ_KERNEL_HANDLE, 0, 0);
Status = ZwCreateFile(&AddressHandle, 0, &ObjectAttributes,
&IoStatusBlock, 0, FILE_ATTRIBUTE_NORMAL, ShareMode, FILE_OPEN, 0,
pEaBuffer, EaLength);
if(NT_SUCCESS(Status))
{
Status = ObReferenceObjectByHandle(AddressHandle, 0, 0,
KernelMode, (void**) &AddressFileObject, 0);
ZwClose(AddressHandle);
}
