Incoming SDP connection will still be rejected even if l2cap_security_level_0_allowed_for_PSM() returns true.

I think that's a bug in l2cap.c, line 914.

The condition should be

!l2cap_security_level_0_allowed_for_PSM(psm)

other than

l2cap_security_level_0_allowed_for_PSM(psm).

Sorry for my poor English.

Thanks for spotting this. You're right. I've fixed it in r2354
