openwrt: Issue finding interfaces

[kimocoder]

Hi!

We seem to have an issue with listing adapters on OpenWRT at the momen. I attached the strace log from "hcxdumptool -i wlan0 -w capture.pcapng" cmd output/trace :+1:

airmon-ng and everything else works fine, but hcxdumptool has issues calling "/sys/class/ieee80211/phy1/device/driver" it seems. finding adapters.

1. Comment (the above)
2. Comment field (below) is in standard operation mode, managed.
3. Comment field is host information (the basics)
4. Comment field is strace/trace output from a adapter managed by "airmon-ng" in monitor mode

[ZerBea]

strace is not helpful in this case, because hcxdumptool use NETLINK to retrieve the interface list instead of requesting it directly from "/sys/class/ieee80211/phy1/device/driver":

static bool get_interfacelist(void)
{
static size_t i;

nl_get_familyid();
if(nlfamily == 0)
    {
    errorcount++;
    return false;
    }
nl_get_regulatorydomain();
if(nl_get_interfacecapabilities() == false) return false;
if(nl_get_interfacelist() == false) return false;
for(i = 0; i < INTERFACELIST_MAX -1; i++)
    {
    if((ifpresentlist +i)->index == 0) break;
    ifpresentlistcounter++;
    }
if(rt_get_interfacelist() == false) return false;
if(ifpresentlistcounter == 0) return false;
qsort(ifpresentlist, ifpresentlistcounter, INTERFACELIST_SIZE, sort_interfacelist_by_index);
return true;
}

First of all we need to find the exact error: RTNETLINK or NL80211. Please add some debug printf to the function mentioned above to latest git head of hcxdumptool:

static bool get_interfacelist(void)
{
static size_t i;

nl_get_familyid();
if(nlfamily == 0)
    {
    errorcount++;
       fprintf(stderr, "NETLINK general failed to get family ID\n");
    return false;
    }
nl_get_regulatorydomain();
if(nl_get_interfacecapabilities() == false)
    {
       fprintf(stderr, "NETLINK NL80211 failed to get interface capabilites\n");
       return false;
       }
if(nl_get_interfacelist() == false)
    {
       fprintf(stderr, "NETLINK NL80211 failed to get interface list\n");
       return false;
       }

for(i = 0; i < INTERFACELIST_MAX -1; i++)
    {
    if((ifpresentlist +i)->index == 0) break;
    ifpresentlistcounter++;
    }
if(rt_get_interfacelist() == false)
    {
       fprintf(stderr, "RTNETLINK failed to get interface capabilites\n");
       return false;
       }
if(ifpresentlistcounter == 0) return false;
qsort(ifpresentlist, ifpresentlistcounter, INTERFACELIST_SIZE, sort_interfacelist_by_index);
return true;
}

Than run: call function to get Iinterface (L)ist $ hcxdumptool -L and to: call function to get interface (I)nformation $ hcxdumptool -I INTERFACE

If we need to debug NETLINK we have to add a NETLINK MONITOR INTERFACE:

$ sudo ip link add  nlmon0 type nlmon
$ sudo ip link set dev nlmon0 up

Now the communication between hcxdumptool and the kernel can be monitored via tshark or Wireshark or tcpdump.

Next step is to debug NETLINK:

[ZerBea]

My candidates:

either RTNETLINK is broken socket(AF_NETLINK, SOCK_RAW | SOCK_CLOEXEC, NETLINK_ROUTE)

or GENERIC NETLINK (NL80211) is broken socket(AF_NETLINK, SOCK_RAW | SOCK_CLOEXEC, NETLINK_GENERIC)

BTW: It is mandatory that you use latest git head of hcxdumptool which received a lot of openwrt NETLINK fixes!

This version has been confirmed as working: https://github.com/ZerBea/hcxdumptool/discussions/382#discussioncomment-7859354

Since v6.3.0 hcxdumptool has the option to add a Berkeley Packet Filter. This is flexible, really fast and thousand times better than doing this by soft coded filter lists https://github.com/ZerBea/hcxdumptool/discussions/420

Yup, "Failed to get interface list"

[ZerBea]

That's interesting. I've added tons of debug messages. Every single call got one.

[ZerBea]

But I have an idea.

[ZerBea]

Same procedure: hcxdumptool.c.zip

Output should look like this:

$ ./hcxdumptool -l

NETLINK ifname  wlp22s0f0u9u4

[ZerBea]

airmon-ng is not affected, because it read the interface information directly from "/sys/class/ieee80211/phy1/device/driver" and not via NETLINK.

[kimocoder]

Ok, let me check :100:

Looks like only kernel 5.15 is affected, while others are working fine. The workaround should be fine, as long as ifindex starts at 1. If not, we got a big problem.

Yeah! thanks a lot, a router without hcxdumptool and a 256gb usb3.2 disk, is not a proper router :1st_place_medal:

[ZerBea]

I wouldn't call this a router... It's an evil and hungry beast!

[ZerBea]

I've tested opwnwrt on different Raspberries ant can confirm this behavior: Raspbian: first deviice = phy1 Arch Linux: first deviice = phy1 Debian: first deviice = phy1

OpenWRT (23.05.0): first device = phy0 (what a surprise)

On all distributions: first ifindex is always 1 (increase on every new connected or reconnected device)

[ZerBea]

Reopened, due to a huge problem:

# iw list
Wiphy phy1
    wiphy index: 1
...
Wiphy phy0
    wiphy index: 0

# iw dev
phy#1
    Interface wlan0
        ifindex 5

# ip addr
5: wlan0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN qlen 1000

Using getifaddrs() doesn't show wlan1:

# ./gi
 ifindex: 1 ifname: lo      
 ifindex: 4 ifname: eth0    
 ifindex: 5 ifname: wlan0   
 ifindex: 6 ifname: br-lan  

Regardless what I'm doing to detect the interface, If the interface has not been created before, hcxdumptool fails to detect it and it can't use it. Looks like this is OpenWRT specific (Arch & Debian are working as expected),

If have to refactor the entire detection of interfaces.

[ZerBea]

Looks like OpenWRT is doing something very special here: 3 devices present(2x USB and 1 x Raspberry Pi soc);

# iw list | grep phy
Wiphy phy2
    wiphy index: 2
Wiphy phy1
    wiphy index: 1

Expected, because the Broadcom chip dos not support monitor mode

Not expected
# iw dev wlan1 set type monitor
command failed: No such device (-19)

Not expected
# iw dev wlan2 set type monitor
command failed: No such device (-19)

Any ideas?

I don't think that's the intention! The only solution is to assign the unassigned devices - but I don't like this idea.

[ZerBea]

I think I got a solution:

# ./hcxlabtool
phy: 1 driver: brcmfmac
phy: 0 driver: rtl8xxxu

I can now retrieve all the information. But unfortunately, I have to hijack all unassigned interfaces to find the best one.

[kimocoder]

bcm has monitor mode and injection via Nexmon

[ZerBea]

Thanks for the information. I'm now able to detect unassigned devices running OpenWRT on a Raspberry Pi Zero w. Next step is to hijack them.

Than I'll move from using IFINDEX:

 * @NL80211_CMD_SET_CHANNEL: Set the channel (using %NL80211_ATTR_WIPHY_FREQ
 *  and the attributes determining channel width) the given interface
 *  (identifed by %NL80211_ATTR_IFINDEX) shall operate on.
 *  In case multiple channels are supported by the device, the mechanism
 *  with which it switches channels is implementation-defined.
 *  When a monitor interface is given, it can only switch channel while
 *  no other interfaces are operating to avoid disturbing the operation
 *  of any other interfaces, and other interfaces will again take
 *  precedence when they are used.

to WIPHY:

 * @NL80211_CMD_SET_WIPHY: set wiphy parameters, needs %NL80211_ATTR_WIPHY or
 *  %NL80211_ATTR_IFINDEX; can be used to set %NL80211_ATTR_WIPHY_NAME,
 *  %NL80211_ATTR_WIPHY_TXQ_PARAMS, %NL80211_ATTR_WIPHY_FREQ,
 *  %NL80211_ATTR_WIPHY_FREQ_OFFSET (and the attributes determining the
 *  channel width; this is used for setting monitor mode channel),

Due to the same reasons I'll check if the user tries to run hcxdumptool on a VIF. If that is the case, I'll remove it.

[ZerBea]

If you take a look at the latest commits on hcxlabtool you'll notice massive changed related to OpenWRT: https://github.com/ZerBea/wifi_laboratory And it's not even all the changes and there is still a lot of work to be done. But I think it is worth it, due to OpenWRTs incredible performance and well suited drivers.

Starting in February 2022, support for ARMv5 and ARMv6 architectures will be ended in Arch Linux ARM: https://archlinuxarm.org/forum/viewtopic.php?f=3&t=15721 OpenWRT is by far the best alternative.

[ZerBea]

Last but not least I got it. The problem is not related to hcxdumptool and there is no need to hijack devices that are not assigned.

The real cause is related to OpenWRT's wireless configuration in /etc/config/wireless. By default the devices are configured to a PATH: option path 'platform/101c0000.ehci/usb1/1-1/1-1.1/1-1.1:1.0' That will not work, if the USB port has been changed.

A better solution e.g. for a Raspberry Pi Zero W (on board radio and one radio attached to the USB port) is to assign them to the physical address (phy).

config wifi-device 'radio0'
        option type 'mac80211'
        option phy 'phy0'
        option channel '1'
        option band '2g'
        option htmode 'HT20'
