ok i did…but now i have another problem:
i set as packethandler my function newfunction
VOID newfunction(IN NDIS_HANDLE MiniportAdapterContext,IN PPNDIS_PACKET
PacketArray,IN UINT NumberOfPackets
){
PADAPT pAdapt = (PADAPT)MiniportAdapterContext;
NDIS_STATUS Status;
UINT i;
for (i = 0; i < NumberOfPackets; i++){
PNDIS_TIMER timer = (PNDIS_TIMER)ExAllocatePool(NonPagedPool,
sizeof(NDIS_TIMER));
PNDIS_PACKET Packet = PacketArray[i];
UINT delay = 80;
struct struttura *strut = ExAllocatePool(NonPagedPool, sizeof(struct
struttura));
strut->hand=MiniportAdapterContext;
strut->pack=Packet;
strut->pad=pAdapt;
NdisInitializeTimer(timer,pippo,strut);
DbgPrint(“inizioritardo”);
NdisSetTimer(timer,delay);
DbgPrint(“Doporitardo”);
NdisMSendComplete(ADAPT_MINIPORT_HANDLE(pAdapt),Packet,NDIS_STATUS_SUCCESS);
// Lying Send…
}
}
and pippo function is
VOID pippo(
IN PVOID SystemSpecific1,
IN PVOID FunctionContext,
IN PVOID SystemSpecific2,
IN PVOID SystemSpecific3
){
struct struttura *punt= FunctionContext;
MPSendPacketsEx(punt->hand,punt->pack,punt->pad); —>the third parameter
is different from the original numberofpackets
DbgPrint(“ritardo avvenuto”);
}
in the MPSendPacketsEx i deleted every call to NdisMSendComplete and the
for cycle that i added in newfunction…when i install the driver there is
an error IRQL NOT LESS OR EQUAL…with stop 00000A
maybe there is a memory reference wrong or i can t call MPSendPackets in
that way?? You told me to add to my queue all packets and then delivery
them…but where i must create that queue structure?
thanks!!!

hi!
i must create a function that works before MPSendPackets…so i set as
packethandler a new function, called newfunct…in this i create a NDIS
timer…so when the timer expires it calls the function
VOID pippo(
IN PVOID SystemSpecific1,
IN PVOID FunctionContext,
IN PVOID SystemSpecific2,
IN PVOID SystemSpecific3
)
in this function i want to call the original MPSendPackets, but this needs
as parameters :
MPSendPackets(
IN NDIS_HANDLE MiniportAdapterContext,
IN PPNDIS_PACKET PacketArray,
IN UINT NumberOfPackets
)
How can i pass to pippo these parameters? they are in newfunct…
thanks!

Francesco,
Try using an ndis timer, copy incoming packets to your own queue, and
dequeue when timer expires.

Hi to all! i have a problem: i must create a driver (starting from
passthruex part 2 sample from ndis.com
)
that adds a delay to some packets (in function of their src and dst port).
i know only these two functions to add delay:
KeWaitForSingleObject
KeDelayExecutionThread
that run only at irq level = passive_level…
So functions in passthruex run at dispatch_level so i can use them because s
ystem crash.
My idea is to buffer packets that i must delay in a some kind of structur an
d give anyway the succes response, like the packet was sent…then i deliver
packets in the buffer after the delay wanted…
can it works? the problem is that i don t know how to call a passive_level f
unction from a driver function…
thanks!
p.s. if i add these function in working sample passthruex part 2 there is an
error like: attempt from a DPC routine to a waiting operation
… stop 0…B8
the error with dpc is connected to irq level or is an other problem?
thanks
francesco
