Hi All,
My requirement is as below,
* I have to create a bridge on linux machine (kernel 2.6.23) and it has 2 interfaces(eth0 & eth1)
* I should have the control of Port State Changes (LISTENING,LEARNING,BLOCKING,FORWARDING,DISABLED) and
Only BLOCKING & FORWARDING States I Wud Be Using. I have to ensure that the port state never goes to any other states other than BLOCKING & FORWARDING.
* Other thing is I have to send the control packets using the llc API's & NF_HOOK On both the interfaces and I recieve on LLC_SAP_BSPAN (Service Access Point Of STP)
The Messages I Send Wud be Control Packets Which Have To Pass Through Even If Port State Is BLOCKING...
I Have to form a ring like this
NODE 1 NODE 2 NODE 3
-->eth1 eth0<----->eth1 eth0 <----->eth1 eth0<--
|--------------------------------------------------------------|
What I have done So far is
* I have commented the STP port state change code So that Port wont traverse to any other state.
* I have IOCTL's to Send My Message And I Use LLC API's& NF_HOOK Which STP Uses to achieve sending.
* Recv Part I Do It On STP's stp_bpdu_rcv().
Everything Works Fine But Sometimes It Crashes...
I'm not getting where exactly its breaking Can u please help me with this regard.
I'm getting the BUG: scheduling while atomic: journald ox..
Cheers
Thinkstor
