[Xenomai-help] fata: removing non-linked element...

[Stephan Zimmermann]

Hi,
I just saw the following errormessages while running some tests with my 
application.

"Xenoami: fatal: removing non-linked element, holder=ef9a5794 
qslot=f96f70d0 at include/xenoami/nucleus/queue.h:422"
"Xenomai: Stuck on nucleus lock f96f6380"

Followed by pressing the reset-button...

I Run Xenomai 2.3 rev 2139 on AMD X2, kernel 2.6.17.14, debian sarge.

May this be due to an misbehaviour in my app, or does it look like 
something xenomai related? I am not sure how to interpret these messages.

Thanks in advance, Stephan

I guess you had to hand-copy the message. There should be some back
trace following that is annoying to type. Maybe you can capture it with
a serial console (if your machine still has "legacy" interfaces). Or,
even better, you try to derive a demo code for triggering the bug.

This is nothing your application should be allowed to cause.

This happens when using what skin ?

Sorry, no Backtrace available, the machine crashes so abrupt, that I 
just saw the console stop in the middle of a line (letters cut throgh 
from left to right...). I am trying to work out some demo code.

By the way, same app on my Pentium M (same softwareversions),  won't
crash but tells me " Xenomai: Switching MAINTASK to secondary mode after
exception #14 from user-space at 0xb7f5b352 (pid 9600)"

I use native the skin, including interrupts.

I wasn't able to isolate the section of my code that causes the crash by 
now. The only thing I figured out by now is that the particular crash 
does not happen with 2.3.x rev 2077.
So I guess some change from 2077 to the 2139 revision did break something.
I'll go on trying to make it reproducible in a small demo program.

By the way, I see a Pentium M crash reliable when I do the following, 
don't know if it's related:

- load nucleus and native module
- start / stop my app
- reload the modules
- start my app --> crash

I attached 'screenshots' of a total freeze with backtrace and some 
messages I extracted  from syslog (both on Pentium M).

Could you track the issue a bit more down? There are not to many
"interesting" changes to 2.3.x. A few milestones I found in the ChangeLog:

- 2092: Allow sleeping scheduler locks
- 2108: Before RPI rework

Anything after 2108 only makes sense to dissect when you switch on
XENO_OPT_RPIDISABLE (RPI was buggy until 2139).

Looks like some memory corruption. Your application is not messing
around on raw (kernel) memory and/or hardware? Keep in mind that changes
to the kernel code also moves offsets, potentially unrevealing a
pre-existing corruption that so far just hit harmless regions.

Nope. If this switch is off, RPI is enabled while known to be buggy, right?

So, if you want to check whether RPI causes some trouble or not, so as
to "dissect" what it does, you need to keep this switch off.

Btw, RPI was not buggy so so that it could cause crashes; it was failing
to _always_ keep a thread's priority consistent across domain migration,
which is quite different. IOW, do not start switching on RPIDISABLE
blindly when your box goes south, it's most likely unrelated to what has
been fixed recently.

Well, I recalled some temporary locking changes on RPI somewhere in this
period. My feeling was to better exclude their potential side-effects
from the testing rounds.

This temporary issue that was introduced by #2109 while rewriting the
RPI support has been fixed by #2139, and caused a debug assertion to
trigger (btw, Stephan, make sure to enable CONFIG_XENO_OPT_DEBUG when
testing). So if the tested revisions did include #2139, then we have the
same crash happening, regardless of whether we use the old or (totally)
new RPI implementation anyway.

My point is that we need to be extra careful about not leading people to
disable RPI blindly (at least in its recent and more complete
incarnation) while it's actually _that_ feature which happens to prevent
priority inversions when secondary mode is involved, e.g:
https://mail.gna.org/public/xenomai-core/2007-01/msg00081.html

Hi again,
we did some testing with the different verions you told us on some 
different Systems. I will try to sum up what we experienced.

Testsystems:
--------------------------------------------
SMP1 - AMDx2 with Kernel 2.6.19
SMP2 - AMDx2 with Kernel 2.6.17
PM1 - Celeron M with Kernel 2.6.17 (ETX Industrial Board)
PM2 - Pentium M with Kernel 2.6.17 (Notebook)

Testet revisions where 2077, 2092, 2108, 2184

The test was running and terminating our application continuously, 
reloading xenomai modules between each start.

Results:
--------------------------------------------
SMP1:
The application runs as intended. While rebooting the system the kernel 
showed some backtraces according to bad paages. Revision 2184 leads to a 
complete crashed  System like I described in the original mail (2187 on 
Kernel 2.6.20 does that too). It is possible to work around this crash 
by disabling priority coupling (activating the option in kernel config).

SMP2:
same as SMP1

PM1:
The application runs fine, but only one time, then the system crashes in 
various ways, most often leaving a backtrace like I posted before on a 
totally frozen console.

PM2:
The Application runs fine, only when rebooting one can see some 
backtraces on the console, the beaviour is equal to the SMP systems, 
without that fatal crashing with 'priority coupling' enabled.

Conclusion:
--------------------------------------------
I guess that there are two bugs causing that effects, one related to 
priority coupling, and  one looks like a wild pointer in kernelspace for 
me. I was unable to produce some demo-code demonstarting the effects 
reliable, but I attached some code causing same Backtraces and crashes 
to appear once in a while (tested on PM1). One will have to run it in a 
loop to see the effect.
(reload modules - run program - reload ...)

Additional I attaced the .config of the PM1 machine, cause this one 
crashes most often.

Greetings, Stephan

P.S.: For running the attaced program, you need a 
magic-parallel-port-interrupt-loopback-device. (Connecting pins 9 and 10 
of the parallel port will do the trick.)

Do you know that you are requesting a timer tick rate of 100 kHz? I just
managed to lock up my poor 266 MHz board running your code. :)

Maybe we are seeing all this weird behaviour due to kernel stack
overruns. Try to switch on CONFIG_DEBUG_STACKOVERFLOW and
CONFIG_DEBUG_STACK_USAGE.

/me now watching what happens at 10 kHz...

I-pipe version? 1.7-00/01 was fragile for me too, 1.7-02 looks fine so
far. This could be one bug, anything on 2.6.17 must be something else.

Should be fixable - once we understood what happens here. :)

I've just found an issue which caused rt_queue_delete() to leave
dandling mmapped segments when attempting to remove a busy queue (i.e.
still bound to another descriptor in user-space).

Could you resync with v2.3.x (or trunk) head revision and try again?
TIA,

Hm, updated my machines to 2.6.20 and 2.3.0 rev 2222. I still see ( less
frequent?) some backtraces occuring on my console, either during reboot
or sometimes when running the testprogram and reloading the modules.(see
dmesg snippet below) The Celeron M still crashes often totally.

My main-application still freezes the SMP mashines if I have 'priority
coupling' enabled in kernel-config. Using trunk makes things even worse.
The pc will crash during startup of my app, the testapp I sendt you
works, but i can not shutdown the pc afterwards, because it freezes
completely when terminating kdm.

dmesg tells me the following (2.3.0.2222, 2.6.20, SMP):

Something is corrupting kernel memory.

I did some remark on your test, let's get back to it: You are running
the test at 100 kHz. That /may/ have side-effects like overload, or it
might actually trigger some stack overrun. Did you enable the stack
checks? Can you confirm the problem occurs also at slower tick rates?

Kernel was freshly patched with:

./ksrc/arch/i386/patches/adeos-ipipe-2.6.20-i386-1.7-02.patch

the one from svn rev. 2222

Test was run at 10KHz, but stack-debugging wasn't on, I will repeat it 
and post again...
