Willem de Bruijn 358be65640 selftests/net: add txring_overwrite ... Packet sockets with PACKET_TX_RING send skbs with user data in frags. Before commit 5cd8d46ea1 ("packet: copy user buffers before orphan or clone") ring slots could be released prematurely, possibly allowing a process to overwrite data still in flight. This test opens two packet sockets, one to send and one to read. The sender has a tx ring of one slot. It sends two packets with different payload, then reads both and verifies their payload. Before the above commit, both receive calls return the same data as the send calls use the same buffer. From the commit, the clone needed for looping onto a packet socket triggers an skb_copy_ubufs to create a private copy. The separate sends each arrive correctly.
