[gentoo-user] Problem with open source driver Devolo dLAN USB

[gentoo-user] Problem with open source driver Devolo dLAN USB

[Florian Philipp]

[-- Attachment #1.1: Type: text/plain, Size: 523 bytes --]

Hi!

Currently I'm trying to istall a Devolo dLAN-USB adapter, also known as Power 
Line. [1]

They even provide an open source driver for Linux as a 400kb tarball [2]. 
Unfortunately "make" isn't successful (see make_1.txt). I'll attach the 
problematic devolo_usb.c file and their readme, too.

I hope you can help me.

Thanks in advance!

1.      Overview

        This readme file contains information about installing the USB driver 
        and the configuration program dlanconfig under SUSE Linux and 
        Debian Linux.

	We also describe the configuration of the dLAN adapters.
	The dLAN duo can be connected either via Ethernet or USB ports.
	If both are installed, USB has priority.

	
	More detailed information about Linux commands is available in the 
        man pages. These are accessed by entering: man ifconfig.  

	
--------------------------------------------------------------------------------
2. 	Requirements
	
	First of all check that your system and installation are optimised:


	2.1	SUSE


	SUSE users can use the YAST program to set up the required system 
        components or to check that they are selected in advance. Use the SUSE 
        menu system to select -> Yast and enter your “root” password. In the 
        selection dialogue 'Install and Remove software' choose the 'Selections' 
        filter for a list of all of the system components. 

        To install the USB driver and the configuration program dlanconfig, 
        the following system components must be selected: 
   
		'C/C++ Compiler and Tools' 
		
		'Kernel Development'	(for installing the USB driver)


	2.2	Debian

	Debian users wishing to install the USB driver need the appropriate 
        kernel-headers-xxx, which must be installed in advance. You will find 
        the exact description (e.g. kernel-headers-2.4.27) by entering 
        'uname -a'. Type in the following command to install the kernel 
        headers:
		
		apt-get install kernel-headers-xxx 

	Depending on the configuration, the subsequent installation takes place 
        either automatically from the CD or from the Internet, assuming you 
        have access.


	2.3 	libpcap

	libpcap is a library used by network sniffer programs. It offers these 
        programs an interface for processing and analysing data packets in 
        networks. You will need this library if you translate or write this 
        type of software yourself or if you wish to use the dlanconfig 
        configuration program. 

	Under SuSE Linux, the latest libpcap library is installed as standard. 
        We advise you to check you installation anyway.

	Debian users will have to install the libpcab library themselves. Do 
        this by entering the following command:
		
		apt-get install libpcap0.8-dev 

	Depending on the configuration, the subsequent installation takes place 
        either automatically from the CD or from the Internet, assuming you have 
        access. 

	Note: The devolo package includes a source text version of the libpcap 
        library. You should use this source text version if you have a different 
        distribution which does not include libpcap.  
	  
--------------------------------------------------------------------------------

3. 	USB-driver installation (for USB connection) and the configuration program dlanconfig

	3.1 	Unpack the compressed tar file

	The following command unpacks the compressed tar file on your local 
        computer:
		
		tar xzvf dLAN-linux-package-1.2.tar.gz


	3.2	Installation

	After unpacking the tar file, change to the subdirectory dlanconfig and 
        continue with the installation as follows:

	There are three ways to carry out the installation:

		- The dLAN configuration program dlanconfig only
		- The USB driver for dLAN duo only
		- The dLAN configuration program dlanconfig and the USB driver


	To install the program dlanconfig only:
			
		./configure 
	
		make cfgtool
	
		make install-cfgtool	(as root)
	

	To install the USB driver for dLAN duo only:

		./configure 
	
		make usbdriver
	
		make install-usbdriver	(as root)


	To install dlanconfig and the USB driver:

		./configure 
	
		make
	
		make install 		(as root)
	

	Note:  Entering the following command will cause the USB driver to be 
        automatically loaded after a restart:
		
		cd driver
	
		make installboot	(as root)

	
	Note: If error messages are displayed or if the installation aborts, 
        check that your system meets with the system requirements.  
	 
--------------------------------------------------------------------------------
	
4. 	dLAN duo

	The dLAN duo can be connected either via Ethernet or USB ports.
	If both are installed, USB has priority.

	After you install the USB driver from devolo, your computer will 
        recognise all connected dLAN duo adapters as network 
        interfaces. This means that a dLAN duo can be treated like 
        any other interface, such as an Ethernet port, for example.
	Entering the command 'ifconfig -a' displays all network interfaces. 
        Each dLAN duo adapter has an identifier that consists of 
        'dlanusb' and  a unique number (e.g. "0" for the first device, "1" for 
        the second, etc.).

	Note: The command 'ifconfig -a' can only be executed as "root".  


	4.1 	Configuration - one-time application 
                (e.g. to test the installation)

	Note: All of the IP addresses named here are examples only.


	After listing all of the network interfaces with the command 
	'ifconfig -a', continue with the configuration with the following 
	example entries: 


		ifconfig dlanusb0 198.168.0.1 netmask 255.255.255.0 up 

	
	Note: Make sure that the new IP addresses are not already being used in
	your network and that they lie within your existing range of IP
	addresses! 


	4.2 	Configuration under SUSE Linux — permanent installation	

	Note: This procedure can only be executed as "root". 

	For the permanent installation of the dLAN duo under SUSE 
	Linux, you should create a text file with the necessary information for 
	the adapter. 
	Enter the following information with any text editor (e.g. edit, pico):

	- if IP addresses are to be assigned dynamically: 

		BOOTPROTO='dhcp'     
		STARTMODE='hotplug'  	

	Finally, the file is saved under the unique identifier for the 
	dLAN duo adapter as follows:

 	/etc/sysconfig/network/ifcfg-dlanusb0    
 
	
	- if IP addresses are to be assigned statically:

		BOOTPROTO='static'
		STARTMODE='hotplug'
		IPADDR='192.168.0.1'
		NETMASK='255.255.255.0'

	Note: Make sure that the new IP addresses are not already being used in
        your network and that they lie within your existing range of IP
        addresses!  
	
	Finally, the file is saved under the unique identifier for the 
        dLAN duo adapter as follows:
	
	/etc/sysconfig/network/ifcfg-dlanusb0    


	To define a gateway, create the file
	/etc/sysconfig/network/ifroute-dlanusb0 
        and enter the following information:


		default 192.168.0.253 - -  
 
	
	Note: Make sure that the IP address is the same as that for your 
        gateway. In most cases the network router is the gateway.

	

	To set the DNS server edit the file /etc/resolv.conf as follows:

	
		nameserver 192.168.0.253 
                (IP address corresponds to that of the DNS server)


	Note: Ensure that the IP address corresponds to that of your DNS server.
        In most cases the network router is the DNS server.


 	
	Note: dLAN duo adapters cannot be configured graphically with
        Yast. 

  
	4.3 	Configuration under Debian Linux — permanent installation	

	Note: This procedure can only be executed as "root".   

	Under Debian Linux, the following information is appended to the file
        '/etc/interfaces':

	- if IP addresses are to be assigned dynamically: 

		auto dlanusb0		
		iface dlanusb0 inet dhcp


	- if IP addresses are to be assigned statically:

		auto dlanusb0	
 		iface dlanusb0 inet static
		address 192.168.0.1
      		netmask 255.255.255.0
      		gateway 192.168.0.253	(only required for Internet access)		


	The file '/etc/resolv.conf' must be edited to ensure that the name
        resolution is executed correctly. Enter the IP address for the DNS
        server into this file, e.g.


		nameserver 192.168.0.253	(only required for Internet
                access)


	Note: Ensure that the IP address corresponds to that of your DNS server.
        In most cases the network router is the DNS server.

	
	
	Note: Operating multiple network interfaces can potentially cause
        problems with DNS and routing. We recommend the use of DHCP for the
        assignment of IP addresses so that the DNS and gateway are adapted
        automatically.

--------------------------------------------------------------------------------

5.	dlanconfig    

	Note: The following procedure can only be executed as "root". 

	Entering 'dlanconfig' allows you to configure a HomePlug network. The
        following entry is an example that adds your first local dLAN adapter
       (dlanusb0) to your network:     	

		/usr/local/sbin/dlanconfig dlanusb0

	Note: If a local dLAN adapter is connected via Ethernet, then
        dlanconfig will be started with the identifier of the appropriate
        network card, i.e. if it is connected to the first network card, 
	then the entry is as follows:

		 /usr/local/sbin/dlanconfig eth0
	
	A menu assists you to set the network password for the local and/or
        remote dLAN devices. You also have an overview of all dLAN devices
        installed in your network.  

	5.1	Change password

	You can change the HomePlug password for the local dLAN adapter in the
        menu by selecting the option 'Set local network password' and entering
        the new network password. You will then see a brief confirmation if the
        password was changed without error.
	
	You can change the HomePlug password for a remote dLAN adapter in the
        menu by selecting the option 'Set remote network password'. Enter the
        new network password and the Security ID of the remote dLAN adapter. The
        Security ID is printed on the back of every dLAN adapter. Please observe
        that entering the Security ID (XXXX-XXXX-XXXX-XXXX) is case sensitive.
        You will then see a brief confirmation if the password was changed
        without error.

	5.2 	Overview of the dLAN network

	For an overview of all of the remote dLAN adapters installed in your
        dLAN network, use the menu to access the option 'List remote devices'.
        dlanconfig also displays the connection rates between the local and the
        remote dLAN devices.
	If a remote dLAN adapter is highlighted with the * symbol, then the
        connection rate value has not been updated.

The missing config.h belongs to the linux-headers package. I thought it 
needs to be installed on any gentoo system, did you remove it?
Try "emerge linux-headers". The source compiles fine on my system.

2.6.17-r2 is the latest stable version and is installed...

I'll try 2.6.21 with the gcc64 useflag which is currently disabled (seems to 
date back to 2006.1)

Thanks for the hint!

No, did not change anything. Still the same make output...

I am confused now. I tried another system, and get the same error as you. 
But my source of devolo_usb.c looks different from yours.

Here I have the same include files, but with a local path (linux) instead 
of /usr/include/linux:

#include <linux/config.h>

While I do have /usr/include/linux/config.h, it is not being used. I 
have /usr/src/linux/include/linux/config.h on one machine, but not on the 
other, where compiling fails. Both machines use gentoo-sources. 2.6.18-r2 
has it, 2.6.20-r7 does not. Seems it has become obslete, a comment in the 
file states this, too. Anyway, it seems to be the same 
as /usr/include/linux/config.h, so can just copy or symlink this one.

#ifndef _LINUX_CONFIG_H
#define _LINUX_CONFIG_H
/* This file is no longer in use and kept only for backward compatibility.
 * autoconf.h is now included via -imacros on the commandline

This is what equery shows me:

sys-kernel/linux-headers-2.6.17-r2 (/usr/include/linux/config.h)

So I assume that emerging these headers will sort it out for you.  The access 
rights are:

-rw-r--r-- 1 root root 225 Dec  4  2006 /usr/include/linux/config.h

(this is on a x86 32bit system)

HTH.

Ooops, seems I've attached the wrong file. I played around with it before 
sending an email. Just remove the "/usr/include" in every include command and 
you get the original. 
Anyway, it doesn't make things better. If I change the include line to 
linux/autoconf.h, the other errors do not disappear.

For me it seems like the shared libraries are not compatible any longer. 
Something in usb_fill_bulk_urb changed.

As far as I know, kernel headers and the kernel itself do not need to be of 
the same version, they are completely unrelated.

Success!

I don't understand it but it works now. I've switched back to 
linux-headers-2.6.17-r2 and suddenly it compiles.

I don't understand it because I had them installed while compiling the first 
few times. Maybe they had to be compiled with the current version of gcc...

Thanks everyone!

Aren't these errors warnings only? I get them, too, but I guess they don't 
matter.

I just compiled the code after replacing linux/config.h by linux/autoconf.h, 
except for the warnings all seems to be fine, I can insmod the 
devolo_usb.ko module.

Glad you had success, but at some time you will probably need a newer 
kernel...

You mean kernel-header (or linux-header), I presume.
