Hi~,
I want to get IP address including IPv6 address in Filter Driver, and I try to use OID_GEN_NETWORK_LAYER_ADDRESSES OID to get the network layer addresses, but this OID is not supported in Win7 System (Ndis6.20). I am wondering are there any ways to get the current IP addresses of the Wireless NIC? Thanks~

The NDIS_FILTER_ATTACH_PARAMETERS provides some information, with possible
updates in NDIS_FILTER_RESTART_PARAMETERS. You can use that information to
call the kernel-mode IP Helper API to fetch the details you are looking for.
OID_GEN_NETWORK_LAYER_ADDRESSES is not a queryable OID. Your
FilterOidRequest routine can expect to see higher-level protocols make this
request to set addresses.
There may be other ways.

Take a look at Windows Filtering Platform, if your target OS is Vista+. WFP
can provide that information via a callout. You also do not need a kernel
driver to use WFP.

The IP Helper Function ‘GetUnicastIpAddressTable()’ gives you a table of both IPv4 and IPv6 for all adapters. The IP Helper Functions have the IP management APIs for all kinds of IP information.

Ok, Thanks everyone~ But I want to get the address in Kernel level, any Kernel-mode IP helper APIs could be used to fetch the address I want?
On NT6, the IPHelper API is available in Kernel Mode.
On NT5, you can register for TDI client callbacks and TCPIP will notify you
via the callbacks of address changes. The name of the ‘transport’ (device
object) can be correlated to the Adapter by knowing the NetCfgId (adapter
GUID). This will get the address but not the netmask.
Good Luck,
Dave Cattley

If you would have checked the WDK you would have found that the IP Helper Function ‘GetUnicastIpAddressTable()’ IS a kernel function.
OK, thanks Larry and David~
Now, there is a problem about how to use this function.
My codes:
#include Netioapi.h
…
ADDRESS_FAMILY Family;
PMIB_UNICASTIPADDRESS_TABLE Table = NULL;
NETIOAPI_API NetIoApi = STATUS_NOT_FOUND;
Family = AF_INET;
NetIoApi = GetUnicastIpAddressTable(Family, (PMIB_UNICASTIPADDRESS_TABLE *)&(Table));…
But I get the LNK error 2019:unresolved external symbol _GetUnicastIpAddressTable@8
How could this happen?
Should I include Iphlpapi.lib ?
>From the WDK:
"Driver code that uses the kernel-mode IP Helper functions, MIB structures,
and enumerations that are declared in Netioapi.h must have #include
statements in the following sequence.
#include <ntddk.h>
#include <netioapi.h>
…"
Make sure you are using a Vista or later Build environment.
Good luck,

#include <ntddk.h>

Yes, I declare these header files in this order. and Build Environment is Win7</netioapi.h></ntddk.h>
No. Include netio.lib.
$(DDK_LIB_PATH)\netio.lib
( don’t know why it isn’t mentioned in the current WDK documentation…)

OK, It works~ Thanks very much, Thomas!
It could happen if you do not specify the library to the linker to resolve
the import.
I think you need to add netio.lib to the TARGETLIBS in your SOURCES file.
Good Luck,

Ok, now, All the unicast ip address entries on the local computer will be stored in a table, and I want to read the address for this struct:
typedef struct in_addr {
union {
struct {
u_char s_b1,s_b2,s_b3,s_b4;
} S_un_b;
struct {
u_short s_w1,s_w2;
} S_un_w;
u_long S_addr;
} S_un;
} IN_ADDR, *PIN_ADDR, FAR *LPIN_ADDR;
Of course, inet_ntoa() could convert a network address in a struct in_addr to a dots-and-numbers format string, and it is delcared in the header file Winsock2.h. And I have a test, there would be lots of compile erros if this header file included in the project. I am looking for a function with the same function of inet_ntoa(). [Win7-FilterDriver]
Thanks~

Just fetch the bytes yourself and format them. Something along these lines:
DebugPrint( INFO, DBG_ROUTING,
“XYZ_ChangeRoutesCallback: IP: %d.%d.%d.%d\n”,
pByte[0], pByte[1], pByte[2], pByte[3]
);
Or just print the ULONG as hex. Doesn’t take a rocket scientist to convert
it to something meaningful.
Don’t try to be to fancy with strings and prints in the kernel.

Hi Thomas, Thanks for your great and helpful suggestions.
Hell all ,
A related question , do we have any equivalent function for GetUnicastIpAddressTable() in Xp ? Because i am also trying something similar . I need to get the lP addresses of Wifi devices connected in Xp.
TIA,
Venkatesh.D.N
