BugCheckCode=0xD2 while NAT with wan adapter

OSR_Community_User · October 5, 2001, 5:15am

Happy time always short:(((
Another problem:(((
I am using Passthru to implement NAT. The driver runs
well with two ethernet NICs. If I dont start NAT packet
tranlsation, The driver still runs well with one LAN adapter
and one wan adapter.
But when I start NAT packet translation,After some packets
(always 2 to 4 packets) which comes from LAN adapter are
translated and sended by wan adapter, there is a kernel
bug check occurred.
Softice tell me:
kebugcheckex: bugcheckcode=0xD2 p1=…p2=…,p3=…,p4=…
I could not find what 0xD2 means because it is not list in the
windbg references.
Here is the code I used to redirect the packet:
***********************************************
//translate packet from LAN and send via WAN.
if(pAdapt->IsLocal)
{
if(!TranslateLocalICMPPacket(
pAdapt,
pEthHeader,
iphdr,
icmphdr)) break;
//send packet via global adapter
if (pAdaptList->IsLocal)
{
pAdaptSend = pAdaptList->Next;
} else
{ pAdaptSend = pAdaptList; }
NdisSend(&Status, pAdaptSend->BindingHandle, Packet);
}
//translate packet from WAN and send via LAN
if(!TranslateGlobalICMPPacket(
pAdapt,
pEthHeader,
iphdr,
icmphdr)) break;
//send packet via local adapter
if (pAdaptList->IsLocal)
{
pAdaptSend = pAdaptList;
}
else
{
pAdaptSend = pAdaptList->Next;
}
NdisSend(&Status,
pAdaptSend->BindingHandle,
Packet);
*************************************************
I read DDK document about NDISWAN. Should I queue the packet
and then send it?
Please give me suggestion:)))
Thanks

It’s very difficult to say something definite, because you provide vey few
information. Did not you forget that LAN Ethernet and NDISWANIP has
different MTU?

I just test to translate icmp echo request/reply packet.
ICMP packet’s length always equals to 74 bytes. I think
it doesnt exceed the MTU of NDISWANIP.
I debug the code of PtStatus when NDIS_STATUS_WAN_LINE_UP

_LINE_UP. The value always equals to 0x5DC.

Yes , it is my own packet. When run with two LAN adapters
, it is right.

what is the SendWindow in NDIS_WAN_LINE_UP mean?
Need I queued the translated packet
and send the packet via NDISWAN later?

Yes , it is my own packet. When run with two LAN adapters

You must also insure that the NDIS packet that you allocate for sending is allocated from the packet pool for the adapter taht you are sending on. If you are translating received packets, then understand that the NDIS_PACKET reserved areas are used differently for sending and receieving. See the discussion about NDIS_PACKET reserved areas at:

Thanks Thomas. I read the KB article you suggest.
There are two packets pools in my driver, one for receive and another for send.
And I use NdisMIndicateReceivePacket in my code.
So I guest the problem is not caused by NdisReInitilizePacket??

OSR_Community_User · October 5, 2001, 12:51pm

I examined my code again and read DDK document about ProtocolReceivePacket.
Here is my PtReceivePakcet:

**************************************
INT
PtReceivePacket(
IN NDIS_HANDLE ProtocolBindingContext,
IN PNDIS_PACKET Packet
)
{
PADAPT pAdapt = (PADAPT)ProtocolBindingContext;
NDIS_STATUS Status;
PNDIS_PACKET pOurPacket;
INT ReturnedRefCount;
NDIS_STATUS MPPacketStatus;
BOOLEAN bDuplicatePacketData = FALSE;
PRSVD PktContext;
// Repackage The Original Packet In New NDIS_PACKET
bDuplicatePacketData = FALSE;
pOurPacket = IMRepackagePacket( pAdapt, Packet);
if( !pOurPacket )
{
return 0;
}
//translate packet and send via another adapt
if (pAdapt->NatState == 1)
{
if (RePackageEtherFrame(pAdapt, pOurPacket))
{
return 0;
}
}
NdisMIndicateReceivePacket( pAdapt->MiniportHandle, &pOurPacket, 1 );
Status = NDIS_GET_PACKET_STATUS( pOurPacket );
if( Status != NDIS_STATUS_PENDING )
{
IMFreePacketAndBuffers( pOurPacket, pAdapt );
ReturnedRefCount = 0;
}
else
{
ReturnedRefCount = 1; // up the ref count on the packet
}
return ReturnedRefCount;
}
**************************************
The error may be occurred at
pOurPacket = IMRepackagePacket( pAdapt, Packet);
if( !pOurPacket )
{
return 0;
}
//translate packet and send via another adapt
if (pAdapt->NatState == 1)
{
if (RePackageEtherFrame(pAdapt, pOurPacket))
{
return 0;
}
}
After IMRepackagePacket, pOurPacket–>protocolreserved.OriginalPkt = Packet;
Here ProtocolReserved of packet is defined as:
typedef struct _ProtRsvd
{
LIST_ENTRY qLink; // Not Used During Indications…
PNDIS_PACKET OriginalPkt;
} RSVD, *PRSVD;
#define PROTOLRSVD_FROM_PACKET( _pkt ) \
((PRSVD)((_pkt)->ProtocolReserved ))
In RepackageEtherFrame, I dont not change the OriginalPkt and if the packet
need to be redirected , PtReceivePacket return zero.
Because I called NdisSend in RepackageEtherFrame, and when send complete,
MpSendComplete will be called.
In MpSendComplete, I called
NdisReturnPakcet(OriginalPkt, 1);

Here maybe the error. DDK saids
“When ProtocolReceivePacket returns zero,
NDIS either calls another bound protocol
with the receive indication or returns
the given packet descriptor at Packet to
the miniport that made the indication.”
It means that if PtReceivePacket returns zero, the Packet descriptor
will be returned by NDIS. But at the same time or later
MpSendComplete is called and then NdisReturnPacket. But
now the ownership of the originalpkt is not retain by my driver.
Is it right?

I just test to translate icmp echo request/reply packet.
ICMP packet’s length always equals to 74 bytes. I think
it doesnt exceed the MTU of NDISWANIP.
I debug the code of PtStatus when NDIS_STATUS_WAN_LINE_UP
to see the value of MaximumTotalSize in structure of NDIS_WAN
_LINE_UP. The value always equals to 0x5DC.
