Subject: can: expected receive behavior broken

Hi,

I just noticed that the receive behavior of CAN sockets is broken
in current net-next-2.6.
I wrote some simple code that receives messages and echos them back to
the bus. When I now trigger one single message on the bus, I get
this message received and echoed back in an endless loop.

I do not touch the sockopts CAN_RAW_LOOPBACK or CAN_RAW_RECV_OWN_MSGS in my code.
Only (!) setting CAN_RAW_LOOPBACK to 0 helps at the moment. But this behavior
actually has nothing to do with LOOPBACK but more with RECV_OWN_MSGS.

Matthias
