TDI and IPv6
in [Device Drivers]

From: Anatoly Greenblatt on 1 Aug 2007 08:49 Hi, I want to open a udp ipv6 connection in XP kernel. I am using the following code but it fails in zwcreatefile with status 0xc0000207. Apparently the tcpip!GetAddress routine return error if AddressType != TDI_ADDRESS_TYPE_IP. Any ideas ? How should I open ipv6 transport address ? A sample code would be highly appreciated. Thanks, Anatoly. NTSTATUS CreateIPv6Address(PHANDLE pTdiHandle, PFILE_OBJECT *pFileObject) { NTSTATUS NtStatus = STATUS_INSUFFICIENT_RESOURCES; UNICODE_STRING usTdiDriverNameString; OBJECT_ATTRIBUTES oaTdiDriverNameAttributes; IO_STATUS_BLOCK IoStatusBlock; char DataBlob[sizeof(FILE_FULL_EA_INFORMATION) + TDI_TRANSPORT_ADDRESS_LENGTH + 300] = {0}; PFILE_FULL_EA_INFORMATION pExtendedAttributesInformation = (PFILE_FULL_EA_INFORMATION)&DataBlob; UINT dwEASize = 0; PTRANSPORT_ADDRESS pTransportAddress = NULL; PTDI_ADDRESS_IP6 pTdiAddressIp6 = NULL; RtlInitUnicodeString(&usTdiDriverNameString, L"\\Device\\Tcp"); InitializeObjectAttributes(&oaTdiDriverNameAttributes, &usTdiDriverNameString, OBJ_CASE_INSENSITIVE | OBJ_KERNEL_HANDLE, NULL, NULL); RtlCopyMemory(&pExtendedAttributesInformation->EaName, TdiTransportAddress, TDI_TRANSPORT_ADDRESS_LENGTH); pExtendedAttributesInformation->EaNameLength = TDI_TRANSPORT_ADDRESS_LENGTH; pExtendedAttributesInformation->EaValueLength = TDI_TRANSPORT_ADDRESS_LENGTH + sizeof(TRANSPORT_ADDRESS) + sizeof(TDI_ADDRESS_IP6); pTransportAddress = (PTRANSPORT_ADDRESS)(&pExtendedAttributesInformation->EaName + TDI_TRANSPORT_ADDRESS_LENGTH + 1); pTransportAddress->TAAddressCount = 1; pTransportAddress->Address[0].AddressType = TDI_ADDRESS_TYPE_IP6; pTransportAddress->Address[0].AddressLength = sizeof(TDI_ADDRESS_IP6); pTdiAddressIp6 = (TDI_ADDRESS_IP6 *)&pTransportAddress->Address[0].Address; RtlZeroMemory(pTdiAddressIp6, sizeof(TDI_ADDRESS_IP6)); dwEASize = sizeof(DataBlob); NtStatus = ZwCreateFile(pTdiHandle, FILE_READ_EA | FILE_WRITE_EA, &oaTdiDriverNameAttributes, &IoStatusBlock, NULL, FILE_ATTRIBUTE_NORMAL, 0, FILE_OPEN_IF, 0, pExtendedAttributesInformation, dwEASize); if(NT_SUCCESS(NtStatus)) { NtStatus = ObReferenceObjectByHandle(*pTdiHandle, GENERIC_READ | GENERIC_WRITE, NULL, KernelMode, (PVOID *)pFileObject, NULL); if(!NT_SUCCESS(NtStatus)) { ZwClose(*pTdiHandle); } } return NtStatus; }
From: TarasCo on 1 Aug 2007 11:02 Have you installed "Advanced Networking Pack for Windows XP"? And You probably should note \Device\Tcp6 instead of \Device\Tcp.
From: Anatoly Greenblatt on 1 Aug 2007 12:41 Thanks Taras, But if I want to make a UDP6 connection, should I open \device\tcp6 ? Do you have any example that uses \device\udp? Thanks again, Anatoly.

No. For UDP, he needs \Device\Udp and \Device\Udp6 -- Maxim Shatskih, Windows DDK MVP StorageCraft Corporation maxim(a)storagecraft.com http://www.storagecraft.com "TarasCo" <tarasc0inbox(a)gmail.com> wrote in message news:1185980520.157063.138810(a)g4g2000hsf.googlegroups.com... > Have you installed "Advanced Networking Pack for Windows XP"?
