[parisc-linux] DSL on a 715/80 with rp-pppoe

[parisc-linux] DSL on a 715/80 with rp-pppoe

[Hinrich Aue]

Hi there,

I tried to install rp-pppoe on my 715/80, and it worked until one point, when 
I try to start the pppd and the box crashes instantly.

There is a massive stackdump or so, and I don't know how to catch it up and 
submit it :-(

perhaps it's a ppp problem.

Another strange thing is, that I succsessfully load the ne Module for my 
ne2000 ISA Adapter in my  715/80, but there's also a stackdump:

Does anyone know what that means?
Any experiences?
Does anyone have a modem running on a parisc-box?

I was running ppp over a regular 28.8Kbps dialup modem on the c3k.
Haven't tried it recently.
Can you tell me which kernel version (uname -a) you are using?
offhand, I'd suggesting trying the latest available from
	ftp://ftp.parisc-linux.org/kernels/32

Hallo,

I found out, that you (Grant Grundler) already had the
same? Problem. There already was a submitted Bug.
Has somebody tried to fix that?

My error output looks like the one discribed at:

http://bugs.parisc-linux.org/db/13/132.html

I'll post the stackdump later today, from syslog.

Either Richard Hirst or Thomas Bogendoerf already fixed that.
132 should be closed since last I tried, I was able to use pppd
with the dialup modem. Sorry about that - I should have closed it.

The "trap 15" is a kernel crash. That doesn't get logged
to syslog (afaik). Are you sure it's the same symptom?

Yes, I found no logging in syslog. I'm not used to kernel stuff, (2. 
semester) but the stackdump looked familiar. And after all, it happens when I 
start pppd with async ppp. If I don't activate async ppp It don't crashes, 
but it don't work. That was a problem first when I tried to use DSL. After I 
activated async ppp the machine crashes at the start of pppd.
I also tried the latest CVS kernel Verison (pa27).
I would like to dig in that stuff, but I don't know where to start and have 
too little experience.

I read another posting, that pppd misses the /sbin/hotplug script.
First I made a script like discribed in the posting, after that I installed 
the hotplug package, both versions had the same problem.

if I do pppd call dsl-privider:
//---------------------------------------
Serial connection established.

LCP terminated by peer
sent [LCP TermAck id=0x68]
Script pppoe -I eth1 finished (pid 297), status = 0x0
Modem hangup
Connection terminated.
//---------------------------------------

It seems strange to me, that the missing hotplug script causes the trap 15.
As I see, there some send and reciieve things done like <auth pap> and stuff.

Q:
Does anybody know why:
"read /dev/ppp: Resource temporarily unavailable"
and
"kernel does not support PPP filtering" ?
What the hell is PPP filtering? Do I have to activate it in the Kernel?
I think that "read /dev/ppp: Resource temporarily unavailable" Is not the 
Problem, perhaps it takes time to init or stuff, but after a while it seems 
to be available, because some messages are recieved and sent.

Hi Hinrich,

> rcvd [LCP ConfReq id=0x66 <mru 1492> <auth pap> <magic 0x3ddff70f>]
> sent [LCP ConfRej id=0x66 <auth pap>]

You reject to identify yourself. Is your userid / password setup 
correctly in /etc/ppp/pap-secrets?

Cheers,
Jochen

Hi Hinrich,

> sent [LCP ConfRej id=0x66 <auth pap>]

I guess you use T-Online (TDSL flatrate?). In this case make sure you 
place the userid in /etc/ppp/pap-secrets in single quotes or the # will be 
treated as a start of comment:

'AAAAAAAAAAAATTTTTTTTTTTT#0001@t-online.de'     *       PPPPPPP        *

Of course you must replace the A, T and P with the data you got from 
t-online.

Cheers,
Jochen

Just a suggestion: Networking Options -> Socket Filtering (CONFIG_FILTER).
This is not enabled by default.

I have a 712/80 which blows up when trying to use ppp with pptp.

I have grabbed the stack trace I get from my system blowing up but have
not managed to get ksymoops to interpret it at all. I have attached the
stack trace in case anyone can make any sense of it.

Does anyone have any ideas what else I could try?

IIRC, when I first got ppp working on hppa, it would only work if
I created a dummy /sbin/hotplug, see

Ok. That sounds similar.

There must be some kernel beginners guid some place...perhaps this
is the start of one for parisc:
1) collect console output from a serial console. Or type in by hand
   panic/crash reason, GR02, IOAQ, and IIR registers for starters.
   Note machine model, PDC firmware rev too.

2) get "a.c" and "astk" from CVS
	http://cvs.parisc-linux.org/~checkout~/build-tools/

3) use "a" to lookup up symbols names in your matching System.map.
   Feed the stack dump to "astk" to get a rough idea of what was
   on the stack. parisc stack grows upward - higher addresses are the
   "top" of the stack - some of the addresses are residual junk.
   Look at the source code to see which functions are really being called.

4) keep notes!
   which kernel versionso, which symtoms, local changes you've made.

5) search the parisc-linux mail archive for "stack dump" or "trap 15"
   (or whatever the panic output is or kernel symbols associated
   with it).

6) post questions to parisc-linux when you get stuck.

Until I restarted ppp on my 712 it had been working perfectly for nearly
three months with no /sbin/hotplug.

Unfortunately I am a sad unstable addict (I have been since pre-buzz days
on i386) and have updated many times since ppp was last restarted.

This one I find weird because I know that it has worked but broke sometime
recently. The only reason I restarted the system was to finally upgrade to
the 2.4.16 kernel I have been happily running on a C160 and a collection
of C110s.

I have tried the syntax you told me, but, I still reject to <auth pap>.
This is strange, couse I think that I reject to auth myself.
"sent [LCP ConfRej id=0x66 <auth pap>]"
 So this must be a config Problem. Do I have to put something else into my 
pap-secrets?
I don't think that auth fails, but somethings wrong with my pap-secrets.

Is it possible you now have CONFIG_HOTPLUG=y, and didn't before?

Does adding a fake sbin/hotplug fix it?

[parisc-linux] DSL on a 715/80 with rp-pppoe

[Hinrich Aue]

Ok, thats what i did.

Girst I had to make the ne2000 run. With pa27-Version
of the kernel the driver loaded without problems, and
I started.
The first big Problem was the missing /sbin/hotplug
script. That caused a massive trap15.
I first inserted a dummy script, but something else
was wrong, and I thought it was the dummy-script. So I
made apt-get install hotplug, which installed another
/sbin/hotplug script, but nothing changed of course.
Than I found an excellent howto (german one) 
http://www.adsl4linux.de
that helped me alot to configure stuff.

I think rp-pppoe performs better than pppoed, and is
much more stable.

I think the main Problem lies between my ears, because
I never installed debian, and it's hard to configure.

If somebody has questions, My email is H_Aue@t-online.de

Not hard, just different.

The 2.4.9 Debian kernal package had hotplug disabled but the 2.4.16
package has it enabled. After a quick apt-get install of hotplug I have a
happy system again. I have filed a bug report to Debian on the kernel
package requesting a dependency on hotplug. This is obviously not the real
fix that is needed, but it would at least prevent this kind of problem for
anyone else.

Nah, that's the wrong answer.  The kernel shouldn't crater if hotplug isn't
present.

Slapping another dependency on the kernel image packages would mask the 
problem instead of fixing it, so I'm uninclined to implement this request.
Better someone track down and fix what's actually blowing up in the kernel,
I think.

IIRC this is tied up with the __execve code in arch/parisc/kernel/entry.S:

        bl      sys_execve, %r2
        copy    %r16, %r26

        cmpib,=,n 0,%r28,intr_return    /* forward */

>>>>>>  /* yes, this will trap and die. */
        copy    %r15, %r2
        bv      %r0(%r2)
        nop

which does not handle sys_execve failing when invoked from the kernel.
We had the same problem when /sbin/modprobe didn't exist.
