Description Bipin Chandra 2017-07-19 12:00:41 UTC

raspberry pi zero have a kernel module which allows it to use the OTG port to generate a virtual USB Ethernet adapter (RNDIS Gadget) and we can define its host and device mac id and it works fine connecting the pi to mac OS, windows or Linux but when you connect it to pfsense or any FreeBSD based system then those ignore the supplied mac id and they always generate a random mac id making it almost useless to be able to use on pfsense etc. I had reported this on the pfsense bug request portal and i was told to report it here.

when the pi is connected to pfsense using USB the below is generated

ugen0.2: <Linux 4.9.37+ with 20980000.usb> at usbus0
cdce0: on usbus0
cdce0: No valid alternate setting found
device_attach: cdce0 attach returned 6
cdce0: on usbus0
cdce0: faking MAC address
ue0: on cdce0
ue0: Ethernet address: 2a:3f:38:a3:80:00

Do you get the same MAC on macOS / Windows / Linux?

Independent of obtaining the "proper" MAC address the current approach for generating a randomized MAC (from r184610) is somewhat bogus and should also be revisited.

Comment 3 Hans Petter Selasky freebsd_committer

2017-07-19 20:24:27 UTC

Could you dump the USB messages when this device is connected under FreeBSD:

Note the numbers after ugenX.Y:

Before plugging the device, run:

usbdump -i usbusX -F Y -s 65536 -vvv > log.txt

After plugging CTRL+C the usbdump.

Likely the Linux OTG module is storing the MAC address in a way that is currently not compatible. This should be easy to figure out by code inspection.

Comment 4 Bipin Chandra 2017-07-20 06:06:30 UTC

i use the below command in the rpi cmdline.txt file to load the module which also sets both the device and host mac id and yes i get the same host mac id on macos/windows/linux

modules-load=dwc2,g_ether g_ether.use_eem=0 g_ether.dev_addr=8e:7a:7e:37:6f:bb g_ether.host_addr=8e:7a:7e:37:6f:aa


usbdump -i usbus0 -f 2 -s 65536 -vvv > log.txt

Can you dump the USB descriptor for this device?

usbconfig -d X.Y dump_curr_config_desc

Can you try the attached patch?

--HPS

Comment 8 Bipin Chandra 2017-07-20 09:17:31 UTC

(In reply to Hans Petter Selasky from comment #6)

i wont be able to test this patch because im using pfsense and im trying to make this work with that and secondly im not a developer so its out of my scope. Ill ask some1 on pfsense forum if they can give it a try

Comment 9 Bipin Chandra 2017-07-24 09:25:56 UTC

tried the patch but the behavior is still same

Comment 10 Bipin Chandra 2017-07-24 12:56:11 UTC

as per one of the members at pfsense i was told the below:

"It still concerns me that the device created is cdce0 and not urndis0. It looks to me as though it's not even using the urndis driver"

It works on 12.1-RELEASE by kldunload if_cdce.ko, after the Zero has booted.
