ozaki-r fe6d427551 Avoid storing a pointer of an interface in a mbuf ... Having a pointer of an interface in a mbuf isn't safe if we remove big kernel locks; an interface object (ifnet) can be destroyed anytime in any packet processing and accessing such object via a pointer is racy. Instead we have to get an object from the interface collection (ifindex2ifnet) via an interface index (if_index) that is stored to a mbuf instead of an pointer. The change provides two APIs: m_{get,put}_rcvif_psref that use psref(9) for sleep-able critical sections and m_{get,put}_rcvif that use pserialize(9) for other critical sections. The change also adds another API called m_get_rcvif_NOMPSAFE, that is NOT MP-safe and for transition moratorium, i.e., it is intended to be used for places where are not planned to be MP-ified soon. The change adds some overhead due to psref to performance sensitive paths, however the overhead is not serious, 2% down at worst. Proposed on tech-kern and tech-net.		2016-06-10 13:31:43 +00:00
