Default Using urndis and error

Hi All,

I have a system that I have converted over to OpenBSD and am attempting to use urndis for phone tethering to get internet access.

Full dmesg will be edited in to [0] when I can pull it from the laptop in a few hours. It is an Acer AO725 if you want some specs in the meantime.
The phone seems to attach correctly and a urndis0 interface is created. I also created a hostname.urndis0 with the line dhcp.
However when I run sh /etc/netstart to get a dhcp address it states: urndis0: no link.

The dmesg then has another line in it which says
Code:
urndis0: ctrl message error: unknown event 0x7
The phone is a Galaxy S4 running stock Samsung 4.4.2.
Has anyone had any experience in using urndis devices or this error?

(Side note, I originally tried this on an older Dell laptop which didn't even attach as a urndis interface. After some searching I came upon this [1] which states that some (old) chipsets may have issues with this. Would this be pertinent information to add to the man page?)

I don't think your misc@ reference applies in this situation. Your using amd64 and your uhub1 is ECHI (USB 2.0). In the last post in that thread, Jan (the OP_ had reported that it was reproducable on i386/USB 1.0

I've run urndis(4) in the past with android phones with i386/USB 2.0, so I think the problem you referenced is isolated to USB 1.

The error message is produced by src/sys/dev/sub/if_urndis.c. The five events that are managed are listed in the switch directly above. Those events (initialize, query, reset, keepalive, and set) are defined in if_urndisreg.h in the same directory. There is an x07 defined in that list:
Code:
/* 802.3 link-state or undefined message error. */
#define REMOTE_NDIS_INDICATE_STATUS_MSG    0x00000007
I interpret the error to mean that the phone is requesting a service the driver is not designed to provide.

Well the misc@ post was in regards to a different laptop that I tried with an old chipset and USB 1.0 before this one, but ignore that for now as it's a separate issue and I don't want to add confusion.

Hmm, checking the .c file you mentioned I see the code (~line 239):
Code:
default:
	printf("%s: ctrl message error: unkown event 0x%x\n",
		DEVNAME(sc), letoh32(hdr->rm_type));
	rval = RNDIS_STATUS_FAILURE;
which to me indicates that it is just a generic unknown error and the format of that printf matches the dmesg output.
If it was the error as defined in the header, wouldn't it print out a different error message/format?
I'm not a programmer, and the little bit of C I studied before was basic and a long time ago so I am super rusty, so forgive me if I'm wrong.

However if it is the case that the phone is requesting something that the driver can't give, is there any way to find out that this is or to further debug or disable that from the phone side?

I'm not a C programmer either, but I have watched C programmers make presentations on Youtube.

The C switch/case logic permits the programmer to select from multiple possibilities, and is easier to understand than a long if...then ... else if ... then ... else if ... sequence. The default case is used for none-of-the-above logic.

I don't know anything about urndis(4), other than it just worked for me with my previous phone. My current phone is Android also, but I do not use it with NDIS at this time as my carrier would like to charge me for the privilege while I am using their stock ROM.

It could be that your phone, being newer, is using a newer specification of NDIS than the driver. Wikipedia says that the specification has reached 6.40 in 2012. This driver was written in 2010, and the spec level is not mentioned in if_urndisreg.h or if_urndis.c

You might ask on misc@ if anyone is using urndis(4) with your release of Android, and perhaps with your model of phone, since drivers deployed can vary by handset, wireless carrier (if they provide the ROM), and Android release.

Yep, I have done that also, there are some pretty good talks on the 'net.

Yes, this I understand, I just figured if it had been set in the header then there would be a case statement for that specific hex value that provided a different error message.

Anyways, that's not important. Will do a little more research and see if I can find some tips in the dbsd/fbsd or netbsd sources if they have some updates for urndis or find if the spec has changed much. Then will ask misc@ if they have any ideas.

Thanks for the info!
