Hi,
I did not go through this code in complete. But looks like
you are missing something. ConnectionContext is the one which you
passed when you created your connectionObject. But looks like
you are allocating a connectionContext, instead of using a
connectioncontext which you passed while creating a connection
object. Remember this connection object needs to be associated
with the address object on which you received this ClientEventConnect.
Hope this Helps,
Srin.

Subject: [ntdev] Re: Build Connection in ClientEventConnect in TDI
Client
Hi,
my problem really is in call to TdiCall.
I write my source as you show.
I make connection only when TdiMon is sarted.
If remove TDI_BUILD_THREADCONTEXT i can’t build connection
betwen server and client.
NTSTATUS
ClientEventConnect (
IN PVOID TdiEventContext,
IN LONG RemoteAddressLength,
IN PVOID RemoteAddress,
IN LONG UserDataLength,
IN PVOID UserData,
IN LONG OptionsLength,
IN PVOID Options,
OUT CONNECTION_CONTEXT *ConnectionContext,
OUT PIRP *AcceptIrp
)
{
// NTSTATUS ntStatus = STATUS_SUCCESS;
WORK_QUEUE_ITEM WorkItem;
PDEVICE_OBJECT deviceObject;
IO_STACK_LOCATION
CONNECTION_CONTEXT connectContext;
BUILD_THREAD_CONTEXT BuildThreadContext;
PCLIENT_OBJECT_INFO pClientObjectInfo;
PIRP pIrp;
TDI_CONNECTION_INFORMATION connectInfo;
KdPrint(( “Server: ClientEventConnect: Start! \n” ));
DbgPrintTimeStamp( “BEGIN” );
pClientObjectInfo = ( PCLIENT_OBJECT_INFO )TdiEventContext;
pClientObjectInfo->pClientInfo->Address =
((PTA_IP_ADDRESS)RemoteAddress)->Address[0].Address[0].in_addr;
pClientObjectInfo->pClientInfo->Port =
((PTA_IP_ADDRESS)RemoteAddress)->Address[0].Address[0].sin_port;
connectContext = ExAllocatePool( NonPagedPool,
sizeof( TdiConnectionContext ) );
RtlCopyMemory ( connectContext, // copy connect name
TdiConnectionContext,
sizeof ( TdiConnectionContext ) );
*ConnectionContext = connectContext;
connectInfo.RemoteAddressLength = RemoteAddressLength;
connectInfo.RemoteAddress = RemoteAddress;
//
// Allocate a Irp to accept connection
//
pClientObjectInfo->ppIrp = &pIrp;
KeInitializeEvent( &( pClientObjectInfo->intEvent ), SynchronizationEvent,
FALSE );
ExInitializeWorkItem( &WorkItem, TdiBuildIrpThread, pClientObjectInfo );
ExQueueWorkItem( &WorkItem, DelayedWorkQueue );
( void )KeWaitForSingleObject( &( pClientObjectInfo->intEvent ),
Executive,
KernelMode,
TRUE,
NULL
);
if ( pIrp == NULL ) {
KdPrint(( “ClientEventConnect: ERROR allocate AcceptIrp! \n” ));
return STATUS_INSUFFICIENT_RESOURCES;
}
deviceObject = IoGetRelatedDeviceObject( pTdiTransportObject );
TdiBuildAccept(
pIrp,
deviceObject,
( PFILE_OBJECT )pClientObjectInfo->ConnectObject,
NULL,
NULL,
&connectInfo,
NULL
);
IoSetNextIrpStackLocation( pIrp );
*AcceptIrp = pIrp;
return ( STATUS_MORE_PROCESSING_REQUIRED );
}
