Hi,
Looking around in the DPDK code I've found that it only initializes the
packet metadata (whih contains the struct ofpbuf belonging to the
packet) during setup, as the packet initializer of rte_mempool_create.
That means that every time a packet buffer is released back by OVS to
the buffer pool, it retains ofpbuf state, and it doesn't change when the
poll mode driver use the buffer again to store a new packet. "source"
and "allocated members of ofpbuf shouldn't change, but frame,
l2_pad_size and the offsets does at various places. Even though I
couldn't establish an error scenario yet, I think it's quite dangerous
to leave the packet to inherit the previous packet's ofpbuf.
Or am I missing some place where this piece is reinitialized?
Regards,
Zoltan Kiss
