Trying to make TCP connection in kernel using sample got from this group.
But I always get error as STATUS_EA_LIST_INCONSISTENT.
Here is code snippet:
TdiNameLength = TDI_CONNECTION_CONTEXT_LENGTH;
TdiName = TdiConnectionContext;
RtlInitUnicodeString(&uName, L"\Device\Tcp");
dEaLength = sizeof (FILE_FULL_EA_INFORMATION) + TdiNameLength;
pEaInfo = (PFILE_FULL_EA_INFORMATION)ExAllocatePool(NonPagedPool,
dEaLength);
pEaInfo->NextEntryOffset = 0;
pEaInfo->Flags = 0;
pEaInfo->EaNameLength = TdiNameLength;
pEaInfo->EaValueLength = 0;
RtlCopyMemory(pEaInfo->EaName, TdiName, pEaInfo->EaNameLength + 1);

InitializeObjectAttributes( &ObjectAttrib, // return

dStatus = ZwCreateFile (
phTransport, // return file handle

dEaLength ); // ealength
if ( NT_SUCCESS ( dStatus ) ) // check
for valid return
{
dStatus = ObReferenceObjectByHandle ( //

*phTransport, // handle to open file
GENERIC_READ | GENERIC_WRITE, // access mode
NULL, // object type

NULL ); // handle information
if ( !NT_SUCCESS ( dStatus ) )
{
ZwClose ( *phTransport ); // close

}
}
ExFreePool ( pEaInfo ); // free
