2.6.23.8: kernel panic
Subsystems (2)
Hi,
I have compiled linux kernel 2.6.23.8 for a single board computer based on ARM architecture (EP9302 processor). I have tried to stress the Bluetooth subsystem, creating repeatly a lot of RFCOMM connections to other Bluetooth dongles (installed on remote computers) and I'm able to get a kernel panic in few minutes.

I have also attached the system log. I hope it helps.

Marcel Holtmann
maintainerHi Marco,
Quoted 5 lines
I have compiled linux kernel 2.6.23.8 for a single board computer based on ARM architecture (EP9302 processor). I have tried to stress the Bluetooth subsystem, creating repeatly a lot of RFCOMM connections to other Bluetooth dongles (installed on remote computers) and I'm able to get a kernel panic in few minutes.
it would be good to know if 2.6.24-rc3 shows the same issue and if you could also produce it on x86. And please post some example code that would trigger this issue. I haven't seen this kind of problem so far.
Regards
Marcel

I have done some tests with 2.6.24-rc3 and I get the same kernel panic. I report again some information.

Hi,
I have compiled linux kernel 2.6.23.8 for a single board computer based on ARM architecture (EP9302 processor). I have tried to stress the Bluetooth subsystem, creating repeatly a lot of RFCOMM connections to other Bluetooth dongles (installed on remote computers) and I'm able to get a kernel panic in few minutes.

This problem is caused by the workqueue in hci_sysfs.c, the del_conn is scheduled after the add_conn with same bluetooth address.
Please try this patch:
----------------------------
The bluetooth hci conn sysfs add/del executed in the default workqueue. If the conn del function is executed after the new conn add function with same bluetooth target address, the connection add will failed and warning about same kobject name.
Here add a btconn workqueue, and flush the workqueue in the add_conn function to avoid the above issue.

the patch looks good to me (except some style cleanups). Let me push it to one of my test machines and stress it a little bit. I give you feedback after my testing.

Hi Dave,

This problem is caused by the workqueue in
hci_sysfs.c, thedel_connis scheduled after theadd_connwith same bluetooth address. Please try this patch:
----------------------------The bluetooth hci conn sysfs add/del executed in the default workqueue. If the conn del function is executed after the new conn add function with same bluetooth target address, the connection add will failed and warning about same kobject name.
Here add a btconn workqueue, and flush the workqueue in the
add_connfunction to avoid the above issue.I have applied your patch against kernel 2.6.24-rc3 and I've got the following error:

Hi,Marco
Thanks for testing, could you please try the below patch instead?
Marcel, thanks for consider my patch. there's some recursion problem in flush workqueue in itself, so maybe we should use two workqueue.
Regards
dave
