(NET AIRO)airo.o in kernel 2.4.20 series is crashing.
Last modified: 2013-07-02 22:09:54 EDT
Description of problem: After error message "kernel BUG at skbuff.c:315!" all wireless traffic was dropped. Version-Release number of selected component (if applicable): RedHat Linux Public Beta Phoebe 8.0.93. How reproducible: Haven't tried... Steps to Reproduce: 1. Upgrade RedHat 8.0 to Phoebe Beta 8.0.93; 2. Use Cisco 342 wireless adapter; Actual results: Traffic was dropped after 12 hours. Expected results: Nothing similar.

Hm, looks like the driver didn't handle the BAP error right.
What is this BAP and BAP error? What may cause it?
From http://www.kismetwireless.net/documentation.shtml : "'cisco_cvs': Linux kernel 2.4.20, sourceforge.net CVS driver release Capture interface: wifiX Notes: The new drivers use the interface ethX for normal operation and wifiX for raw packet capturing. The interface for Kismet should be set to wifiX. These drivers have a history of locking up under high loads and when entering/leaving rfmon mode. " As the newer RedHat Linux kernels are 2.4.20 then maybe that is why it crashed on me and perhaps it will crash on other reasons as well?

... 2.4.18 series is working fine.
What is this bug 79579? Any hope to get this fixed or at least confirmed?
Any Idea if or when this is going to be fixed in the kernel for RH 9?
I'm almost the same problems with RH9, first my keyboard stops working, but it appears that I can still do things like check e-mail with the mouse. The last time the keyboard stopped working I tried connecting to my laptop from the network but it was no longer on it, one time it froze up everything and I had to reset it. kernel-2.4.20-9 kernel-pcmcia-cs-3.1.31-13 Message from /var/log/messages May 14 13:51:30 localhost kernel: airo: BAP error 4000 2 May 14 13:51:31 localhost kernel: Warning: kfree_skb passed an skb still on a list (from c01219fa).

*** Bug 97187 has been marked as a duplicate of this bug. ***
According to http://sourceforge.net/tracker/? atid=382983&group_id=24926&func=browse this is related to the firmware version on the card. (i.e. 5.X does this, 4.25.30 does not). However, I run with 4.25.30 firware and it's happening to me. The author of this driver appears to have abandoned it. (Ben Reed) He told me himself he hasn't messed with it in a year. One other person at that URL suggests that the drivers from Cisco don't have this problem. I have not yet been able to verify that, but if true, are they GPL? Can our next kernel update have the cisco drivers?
I managed to reboot the box today and in 4 hours there was "Kernel PANIC!" all over the place - somehow kernel-2.4.20-18.9 has managed to to set itself as default kernel. Can anyone confirm if some newer release (2.4/2.6) of kernel has the aironet driver fixed or when it may happen?
Javier Achirica and Ben Reed worked on it in the last few days. They have posted a 1.53 version of airo.c at sourceforge, in the cvs tree, not in the "files" section. According to Javier, he found a race in the transmission path. Download airo.c and airo.h, put them in the right place in your kernel src tree, make modules, and copy the resulting airo.o into your /lib/modules. Let's hope the major vendors pick up on this fix (if it works) and update the kernel rpm's.
I can confirm that for my situation (vnc via the wireless interface to a laptop also on the wireless) the updated drivers from the sourceforge page work. I have been using vnc via the wireless interface now for the past 20 minutes (usually crashes the kernel after ~2 seconds of heavy traffic). My method for building: 1) Get kernel-2.4.20-8.src.rpm, transfer to the affected machine (could be problematic if the airo wireless is the only network interface ;) - in this case, 'split' and 'cat' are your friends) 2) Install the rpm: rpm -Uvh kernel-2.4.20-8.src.rpm 3) cd /usr/src/redhat/SPECS 4) sudo rpmbuild -bp kernel-2.4.spec (patch a source tree) 5) cd /usr/src/redhat/BUILD/kernel-2.4.20/linux-2.4.20 6) Edit the top level makefile, change 'EXTRAVERSION' from '-pre3' to '-8' 7) Copy the appropriate config from /usr/src/redhat/SOURCES - eg: cp /usr/src/redhat/SOURCES/kernel-2.4.20-athlon.config /usr/src/redhat/BUILD/kernel-2.4.20/linux-2.4.20/.config 8) Get the airo files from sourceforge cvs: see http://sourceforge.net/cvs/?group_id=24926 for instructions on how to do this. The module you want is 'airo-linux' 9) Copy the files from the 'airo-linux/kernel' directory to /usr/src/redhat/BUILD/kernel-2.4.20/linux-2.4.20/drivers/net/wireless 10) build dependencies: make dep 11) build modules: make modules 12) Copy the module object files into the appropriate directory: cp /usr/src/redhat/BUILD/kernel-2.4.20/linux-2.4.20/drivers/net/wireless/airo*.o /lib/modules/2.4.20-8/kernel/drivers/net/wireless *NOTE: you may want to back up the original driver object files first* 13) Bring the wireless interface down (/sbin/ifdown ethN) 14) Unload the old modules: /sbin/rmmod airo airo_cs 15) /sbin/depmod 16) Load the new modules (in my case, /sbin/cardctl eject 0; /sbin/cardctl insert 0) Test it out! Hope this helps. Regards, Richard
I grabbed the 1.53 after Javier fixed it. Copied airo.c and airo.h to /usr/src/linux/blah/blah/blah Edit airo.c to undefine MICSUPPORT (If you want it, get the other .c and .h files from the CVS tree) make modules copied the resulting airo.o up to /lib/modules Works like a charm, haven't had a single problem since doing this. Kernel is 2.4.20-86 Uniprocessor, laptop, Dell Latitude C600
This may or may not be relevant. I never had this problem until I started to run Fluxbox with GKRellM. I have a Dell Inspiron 4150 and an Airo 350. My co-worker has a Sony Vaio R505-EL and he *also* did not have this problem until he started running Flux / GKRellM. We both ditched GKRellM and have never had the problem again.
I am somewhat concerned that the major vendors appear to not have picked up on the update. Last time I checked, everyone's latest distro shipped with 0.6, STILL. Anyone have a clue why this is?
We hesitate to pick up drivers that are not included in the upstream kernel... I'm sure the others have the same or a very similar policy
My kernel RH9 2.4.20-31.9 reports this error when i runn snmpd and mrtg 5min query from another point. Bug crash afther 12 hours.
Thanks for the bug report. However, Red Hat no longer maintains this version of the product. Please upgrade to the latest version and open a new bug if the problem persists. The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases, and if you believe this bug is interesting to them, please report the problem in the bug tracker at: http://bugzilla.fedora.us/
