Why doesn't my MiniportSendPackets get called?

NTDEV
1

Hello All,

I just finished writing a very basic NDIS miniport. It installs okay and
I respond to a bunch of OIDs that come down my QueryHandler, but my
MiniportSendPackets handler doesn’t get called? What else do I need to
do to make this happen. I want to start debugging my sendpackets
routine.

Thanks,
Ravi

I would suggest you run ndistest against you driver, pay attention to the
“mandatory OID” test.
NDIS won’t call MPSendPackets unless ALL mandatory OIDs are handled
properly.

Good luck,
Calvin

Calvin,

Thanks, I installed it and ran it and I see a load of messages when I
run the tests on the right panel (WHQL probably). It runs this one test
called OidsNdisRequest.

  1. Is this the right test 'cause it says “Total 3”, “Passed 2”, “Failed
    1”…

2.How do I interpret the results. I think I am implementing all required
OIDs. Do I need to support additional OIDs if I declare myself a
NdisWirelessLAN device for PHYSICAL_MEDIUM type?

Thanks for your help,

Ravi,

You may have already checked this but check if there are any
'#ifdef’s around where you setup the SendPackets routine and
if these variables are being set when you build the driver.

I had the same problem and it took me some time to realise that
I was setting up the function inside an ‘#ifdef DESERIALIZED’ but
I was not defining the variable when building the driver.

Something really basic and simple but it is something to check for…

Calvin,

Yep I checked and I am returning the right link speed - 11Mbps. I
selected only the OID test this time around and I’ve copied the log. The
one thing I did notice on my debugger was that my SetInformation Handler
is being invoked a few times. Also Ndistest uses IOcontrol and I see
something that says PENDING. Do I have to do anything in the
MiniportSetInformation handler right away for this to work?

Here’s the log:
Variation #1 Loading scripts…
This script performs a series of NdisRequest calls to the driver, to
verify
that it supports the querying of all required information OIDS. This
will query
OID_GEN_SUPPORTED_OIDS, verify that all required oids are present and
query them.

The Ndis Tester is not able to verify the values returned by most
of these OIDs. The user should check this log carefully for problems.

Ravi,

You don’t want to pend and SetInfo forever… Ndis won’t send further
SetInfo if there’s a pending one. Perhaps it is the problem.

Calvin, few more questions:

  1. Do I need to do anything in the INF files to make sure that a

protocol is bound?

  1. I changed my driver to be a simple 802_3 device and I see one

MiniportSetInformation call with OID_GEN_MACHINE_NAME, and that’s it.

  1. Do I need a traffic generator application of sorts to see any

packets? I assumed I will see something like ARP packets right off the

bat in the Miniport and I wouldn’t need a traffic generator app.

I am using a bogus MAC address in the OID that asks for CURRENT_ADDRESS

and PERMANENT_ADDRESS. I hope that’s okay.

thanks Ravi

Ravi,

You don’t want to pend and SetInfo forever… Ndis won’t send further
SetInfo if there’s a pending one. Perhaps it is the problem.

  1. No.
  2. Did you complete it or pend it?
  3. You don’t need a traffic generator. Just do a “ping”.
    Bogus MAC address is fine. Make sure it’s not a multicast/broadcast address.

I complete it with BytesRead set to the right value. Interestingly enough, I see only one OID come to SetInformation - OID_GEN_MACHINE_NAME and it seems like an optional OID.

But I still don’t see my SendPackets called. Is there anyway to find out if the protocol and other higher layers drivers got loaded and bound?

Thanks
Ravi

Ravi,

One thing in the log caught my eyes.

MAC_OPTIONS = 0xCD
Copy Lookahead Data
Receives are not Serialized
Transfers never Pend
NDIS handles Loopback
Transmit’s must be serialized with other requests
802.1p Priority is supported
Mac Address can be Overwritten
802.1q VLAN is not supported

The bit_7 (0x80) is not defined in my DDK. The explanation for that bit
seems to say (Transmit’s must be serialized with other requests)

Did you set the bit in response to an OID_GEN_MAC_OPTIONS query? I
definitely didn’t set this bit in my lan driver.

I would guess NDIS is waiting for something to finish before sending???

Please install a checked build ndis.sys and use ndiskd debugger extension.
Post the output of commands “!ndiskd!miniport xxxxxxxx” and “!ndiskd!mopen
xxxxxxxx”.

Keep me posted, PLEASE…

Ravi,

You can pick up individual test (instead of the full WHQL) to perform.
You
definitely want to fix the failure. The NDIStest log should have
explained
why it’s failing, e.g. which OID. Did you return the correct link speed?
Can
you post the full log for oidtest?

You could compare your code with any of your WHQL’ed drivers. I’ve never
written an 802.11 driver myself. I don’t know what special OIDs need to
be
handled. You may contact Mitesh Desai (MSFT) who had helped me on
ndistest
issues before.

HTH,
Calvin

Calvin,

Hmmmm… This is a dump from nddndis.h in the ddk directory. Which option
are you referring to? I can’t find any option with the description you
mentioned. Could this be a NDIS 5.0/5.1 issue?

//
// Ndis MAC option bits (OID_GEN_MAC_OPTIONS).
//
#define NDIS_MAC_OPTION_COPY_LOOKAHEAD_DATA 0x00000001
#define NDIS_MAC_OPTION_RECEIVE_SERIALIZED 0x00000002
#define NDIS_MAC_OPTION_TRANSFERS_NOT_PEND 0x00000004
#define NDIS_MAC_OPTION_NO_LOOPBACK 0x00000008
#define NDIS_MAC_OPTION_FULL_DUPLEX 0x00000010
#define NDIS_MAC_OPTION_EOTX_INDICATION 0x00000020
#define NDIS_MAC_OPTION_8021P_PRIORITY 0x00000040
#define NDIS_MAC_OPTION_SUPPORTS_MAC_ADDRESS_OVERWRITE 0x00000080
#define NDIS_MAC_OPTION_RECEIVE_AT_DPC 0x00000100
#define NDIS_MAC_OPTION_8021Q_VLAN 0x00000200
#define NDIS_MAC_OPTION_RESERVED 0x80000000

According to this, 0x00000080 is
NDIS_MAC_OPTION_SUPPORTS_MAC_ADDRESS_OVERWRITE even though I am not
setting it. That’s weird. Here’s what I return for this query

ulSourceBuffer = (NDIS_MAC_OPTION_COPY_LOOKAHEAD_DATA |
NDIS_MAC_OPTION_TRANSFERS_NOT_PEND |
NDIS_MAC_OPTION_NO_LOOPBACK |
NDIS_MAC_OPTION_8021P_PRIORITY);

Ravi,

You can pick up individual test (instead of the full WHQL) to perform.
You
definitely want to fix the failure. The NDIStest log should have
explained
why it’s failing, e.g. which OID. Did you return the correct link
speed?
Can
you post the full log for oidtest?

You could compare your code with any of your WHQL’ed drivers. I’ve
never
written an 802.11 driver myself. I don’t know what special OIDs need
to
be
handled. You may contact Mitesh Desai (MSFT) who had helped me on
ndistest
issues before.

HTH,
Calvin

Calvin,

I just realized the following. In my queryInfo handler, I’ve sometimes
returned success when I don’t really support the OID. For instance, I
don’t really care about Custom OIDs for now, and should be returning
NDIS_STATUS_NOT_SUPPORTED when I receive the OID_GEN_SUPPORTED_GUID, but
I don’t. I’ve fixed, this let’s see if this buys me anything.

Ravi

I guess, here’s what I did. I fixed my QueryInformation routine to
return NDIS_SUCCESS if I was supporting the OID, and
NDIS_STATUS_NOT_SUPPORTED if I wasn’t. After I see the network icon in
the tray, I added Microsoft TCP/IP to the list of procotols and voila, I
see my SendPackets handler invoked!!

Now, why does this sequence of OIDs happen endlessly?

OID_GEN_CONNECT_STATUS
OID_GEN_LINK_SPEED
and some kind of statistic query?

thanks
ravi

Good work, dude!

Yes, the network tray applet polls these OIDs periodically. If you hide the
connection icon from the tray, it should stop polling. IIRC, w2k behaves
differently though.

My driver loads and I see my SendPackets routine called but this chain
of OIDs never ends! I return 10Mbps for link speed and
NdisMediaStateConnected for CONNECT_STATUS, it comes right back and asks
me for the same info.

Is there a timeout or something that controls this?

This time around I didn’t even open the network connections tray.

Do you have the network icon in the tray? You will get endless query OID
even you didn’t open the tray as long as the icon was there. You need to
un-check the “Show icon in notification area when connected” box to hide the
icon.

Okay, if that’s true, how does a real network driver work. I have an
icon open on the bottom right of my screen but that doesn’t seem to
freeze up my system. In my case I see so many debug messages that my
system practially freezes. Is it that I have to pend the query and
return it only when the link speed really changes or something?

>Bogus MAC address is fine. Make sure it’s not a multicast/broadcast address.

Also the OP must make sure that this MAC address is never changed for the
lifetime of the adapter. It is queried and cached by NDIS very early, just
after MiniportInitialize and before any protocols are bound.
