AX.25, NETROM and ROSE changes in 2.6.17

For those who haven't read my recent patches I'd like to point out that in the next kernel release, 2.6.17 the units for the AX.25 timers T1, T2 and T3 will change to use ms for all platforms away from the previous chaos of version, architecture, platform and configuration dependentant chaos. I've tried to explain things on

http://www.linux-ax25.org/wiki/Run_time_configurable_parameters
http://de.linux-ax25.org/wiki/Laufzeiteinstellungen

(1st page in English, 2nd in German)

This matters to any sysadmin that is modiyfing the values from their defaults.

Hi,

I compiled OK a new kernel 2.6.16.14 with AX25 for my FEDORA CORE 4 and downloaded from FTP site ftp://f6bvp.org/pub

ax25-apps-0.0.6src.tgz
ax25-tools-0.0.8src.tgz
libax25-0.0.11src.tgz

I make and installed OK ax25-apps-0.0.6src.tgz and libax25-0.0.11src.tgz.

But with ax25-tools-0.0.8src.tgz have the following ERROR on make below at the end of the e-mail.

When I unpacked ax25-tools-0.0.8src.tgz, I see inside in the directory ax25-tools-0.008-2.6.tgz file. I tried tar xvfz ax25-tools-0.008-2.6.tgz and see nothing. What is that file? Is that a patch and how do I apply it?

If somebody can help me. Thanks.

I've dumped a few packages I built for FC4 into

ftp://ftp.linux-mips.org/pub/linux/mips/people/ralf/ax25/

They used to work fine for me on FC4 but I switched to FC5 so there won't be any FC4 updates for these packages anymore.

By the way, its a long time since I want to ask if there is any reason to keep the same name for different ax25.h include files.

-rw-r--r-- 1 root root 4877 mar 21 01:26 /usr/include/netax25/ax25.h [root@bernard tools]# ll /usr/src/linux/include/linux/ax25.h -rw-rw-rw- 1 root root 2752 mar 20 06:53 /usr/src/linux/include/linux/ax25.h [root@bernard tools]# ll /usr/src/linux/include/net/ax25.h -rw-rw-rw- 1 root root 14842 avr 30 11:27 /usr/src/linux/include/net/ax25.h

Somehow it may be confusing.

One for building applications, one for the kernel itself.

I understand that these files have different usage. This is why I think that they should have different names.

Here is the content of /usr/src/linux/include/linux/ax25.h
----------------
/*
* These are the public elements of the Linux kernel AX.25 code. A similar
* file netrom.h exists for the NET/ROM protocol.
*/

#ifndef AX25_KERNEL_H
#define AX25_KERNEL_H
----------------

So why not rename it ax25_kernel.h

I just don't see a convcingint reason for it. If it aint broke don't fix it. Chances are renaming will break some software which against good advice is using the kernel header file anyway.

Ralf

If you really want to get confused, check out how many different versions of netrom.h are laying around.

/usr/include/linux/netrom.h
/usr/include/netax25/kernel_netrom.h
/usr/include/netrom/netrom.h
/usr/src/linux/include/linux/netrom.h
/usr/src/linux/include/net/netrom.h

The bottom line is you should never have the /usr/src/linux kernel includes in your build path if you are building applications.

Subject: Re: different AX25.H files with same names

I have just installed kernel 2.6.16.17 and patched it with your postings. I compiled the kernel with the 1000 Hz timing option.

I wanted to compare my runtime AX25 parameters with your tables in
http://www.linux-ax25.org/wiki/Run_time_configurable_parameters

Here is what is listed when printing /proc/sys/net/ax25/ax0

ll /proc/sys/net/ax25/ax0/
total 0

-rw-r--r--  1 root root 0 mai 21 23:25 ax25_default_mode
-rw-r--r--  1 root root 0 mai 21 23:25 backoff_type
-rw-r--r--  1 root root 0 mai 21 23:25 connect_mode
-rw-r--r--  1 root root 0 mai 21 23:25 dama_slave_timeout
-rw-r--r--  1 root root 0 mai 21 23:25 extended_window_size
-rw-r--r--  1 root root 0 mai 21 23:25 idle_timeout
-rw-r--r--  1 root root 0 mai 21 23:25 ip_default_mode
-rw-r--r--  1 root root 0 mai 21 23:25 maximum_packet_length
-rw-r--r--  1 root root 0 mai 21 23:25 maximum_retry_count
-rw-r--r--  1 root root 0 mai 21 23:25 protocol
-rw-r--r--  1 root root 0 mai 21 23:25 standard_window_size
-rw-r--r--  1 root root 0 mai 21 23:25 t1_timeout
-rw-r--r--  1 root root 0 mai 21 23:25 t2_timeout
-rw-r--r--  1 root root 0 mai 21 23:25 t3_timeout

It appears that dama_slave_timeout and protocol parameters are not in the AX25 table.

ll /proc/sys/net/netrom/
total 0

-rw-r--r--  1 root root 0 mai 21 23:36 default_path_quality
-rw-r--r--  1 root root 0 mai 21 23:36 link_fails_count

-rw-r--r--  1 root root 0 mai 21 23:36 transport_requested_window_size
-rw-r--r--  1 root root 0 mai 21 23:36 transport_timeout

reset parameter is not listed. Not ajustable ?

Here is the listing of ROSE parameters :

ll /proc/sys/net/rose/
total 0

-rw-r--r--  1 root root 0 mai 21 23:33 acknowledge_hold_back_timeout
-rw-r--r--  1 root root 0 mai 21 23:33 call_request_timeout
-rw-r--r--  1 root root 0 mai 21 23:33 clear_request_timeout
-rw-r--r--  1 root root 0 mai 21 23:33 link_fail_timeout
-rw-r--r--  1 root root 0 mai 21 23:33 maximum_virtual_circuits
-rw-r--r--  1 root root 0 mai 21 23:33 no_activity_timeout
-rw-r--r--  1 root root 0 mai 21 23:33 reset_request_timeout
-rw-r--r--  1 root root 0 mai 21 23:33 restart_request_timeout
-rw-r--r--  1 root root 0 mai 21 23:33 routing_control
-rw-r--r--  1 root root 0 mai 21 23:33 window_size

Again, parameter no_activity_timeout is not in the ROSE table.

Any explanations ?

They are only there if CONFIG_AX25_DAMA_SLAVE has been selected.

It's a relativly new thing, the G8ZPT-style NET/ROM circuit resets. It's of course ajustable, the file has "rw" set.

I suppose this was just inherited from the old, less than perfect documentation.
