Subject: FW:  ccid2/ccid3 oopses

Hello !

as suggested by Ian McDonald, i`m forwarding this to dccp and netdev mailing lists.


> hi !
>
> i know dccp_ccid2 and ccid3 modules are considered experimental, but i`m unsure if i probably triggered a bug inside or outside that modules here (i`m no kernel developer)
>
> apparently, i got crashes when loading/unloading other driver modules just after ccid2 or ccid3 had been loaded/unloaded _once_ (have not used them at all, just modprobe module;modprobe -r module)
>
> this was detected during some hardcore module load/unload testing session and apparently these modules seem to be the root cause of other modules crashing, so they seem to leave the system in an inconsistent state after load/unload.
>
> this can be reproduced with recent 2.6.24rc6 kernel which was mostly built with allmodconfig.
> i could not reproduce this with a more minimalistic configuration, e.g. the suse kernel of the day runs fine.
>
> the easiest way to reproduce is:
>
> while true;do modprobe dccp_ccid2/3;modprobe -r dccp_ccid2/3;done
> after short time, the kernel oopses (messages below)
>
> i`m not sure if this is worth to be filed at kernel bugzilla, so i`m contacting you personally first.
>
> i`d happily assist in helping debug this or provide more input (.config etc) if you want to take a look.
