Good evening,

I have installed GNU/Hurd on another laptop and I'm struggling to get the network to work.

When doing ifup /dev/eth0 (for a dhcp setup) I'm getting:

fsysopts: /servers/socket/2: -i /dev/eth0 -a 0.0.0.0 -m 255.0.0.0: (ipc/mig) server died
Error getting interfaces; Translator died
Can't get list of interfaces.

I attach the output of settrans -fga /dev/netdde /hurd/netdde

lspci identifies the card as

02:0e.0 Ethernet controller: Broadcom Inc. and subsidiaries BCM4401-B0 100Base-TX (rev 02)

and lspci -n

02:0e.0 0200: 14e4:170c (rev 02)

The package versions are those of the latest installer images which are from February:

hurd 1:0.9.git20201127-5
netdde 0.0.20200330-6
gnumach 2:1.8+git20201129-4

Is this ethernet card supported?

Regards,
João

Hello,

Off course it is cool to run the Hurd! ;) You should try it out, especially if you are bored. The installer feels the same as the one for linux, so it is rather straightforward. While I had issues with some installer images, the last one from February worked pretty well (I only had some issues when choosing several
locales).
I have not run the system for long enough to see any file system corruption. The
file system is ext2, so you will get the typical fsck run after a hard shutdown (I have seen X hang after some time of inactivity, and was unable to go back
to the console).

How old is the card? I think Broadcam is not the best wifi device, but I'm not positive...

This is an ethernet card, not a wireless card (GNU/Hurd does not have a wireless
stack yet). On linux it works with the b44 driver, but I don't know if that is included in netdde.

Regards,
João

included in netdde.

netdde has that driver, but it doesn't seem to be recent enough for that
card.

Many thanks for clarifying this. This card is quite old (around 2005?), but I guess netdde is also based on an old version of linux drivers.

Is there any hope to get the card working without major netdde overhaul?
I imagine it will be more complicated than just compiling a newer version of the
b44 driver.
If anyone one is familiar with the process or doing this sort of thing already, I would be happy to test or help out in any limited way I can.

João

It's version 2.6.32.65.

The problem is that a new version of a driver usually means using new
versions of the Linux API, etc. so in the end it pulls a lot of new requirements.

We are rather heading toward using rump drivers which are to be much
easier to do such an upgrade.

I'm sorry to come back to this.
I cannot find a list of cards supported by the b44 driver, or which version supports which card, but looking through the code in kernel version 2.6.32.65, guessing from line 107, I would say that this card would be supported. https://elixir.bootlin.com/linux/v2.6.32.65/source/drivers/net/b44.c

I don't know if netdde loops through the drivers in alphabetical order, but looking at the output of
settrans -fga /dev/netdde /hurd/netdde
that would be my guess. And what I see is that after testing atheros drivers, the
e100 intel driver is tested next. Is the b44 driver being skipped?

You mentioned the move to Rump drivers on a different message. This is interesting. I could only find some old documentation about this: https://www.gnu.org/software/hurd/community/gsoc/project_ideas/driver_glue_code.html
Is there more recent information or a roadmap?

You mean line 108?

#define PCI_DEVICE_ID_BCM4401B0 0x4402
#define PCI_DEVICE_ID_BCM4401B1 0x170c

his lspci was showing

lspci -n
02:0e.0 0200: 14e4:170c (rev 02)

So yes possibly it's actually supported in that b44.

However it seems that b44.c is in the blacklist, because it doesn't
build.

Not that I'm aware of. The current focus for rump is for disk support,
to be able to drop disk drivers, and the linux glue from the mach
kernel.

Hello everyone,

I was trying to build netdde with the b44 driver (blacklisted by default), but the compilation breaks at:

#include <linux/ssb/ssb.h>

About SSB I found the following on a commit message to linux:

«The Sonics Silicon Backplane is a mini-bus used on
various Broadcom chips and embedded devices.
Devices using the SSB include b44, bcm43xx and various
Broadcom based wireless routers.
A b44 and bcm43xx port and a SSB based OHCI driver is available.»

Would there be any hope of getting this working on the Hurd, or it depends too much on linux own driver infrastructure?

Best regards,
João
