Subject: [PATCH net 0/7] virtio_net: Fix problems around XDP tx and napi_tx
Date: Thu, 17 Jan 2019 20:20:38 +0900	[thread overview]
Message-ID: <1547724045-2726-1-git-send-email-makita.toshiaki@lab.ntt.co.jp> (raw)

While I'm looking into how to account standard tx counters on XDP tx
processing, I found several bugs around XDP tx and napi_tx.

Patch1: Fix oops on error path. Patch2 depends on this.
Patch2: Fix memory corruption on freeing xdp_frames with napi_tx enabled.
Patch3: Minor fix patch5 depends on.
Patch4: Fix memory corruption on processing xdp_frames when XDP is disabled.
  Also patch5 depends on this.
Patch5: Fix memory corruption on processing xdp_frames while XDP is being
  disabled.
Patch6: Minor fix patch7 depends on.
Patch7: Fix memory corruption on freeing sk_buff or xdp_frames when a normal
  queue is reused for XDP and vise versa.

Toshiaki Makita (7):
  virtio_net: Don't enable NAPI when interface is down
  virtio_net: Don't call free_old_xmit_skbs for xdp_frames
  virtio_net: Fix not restoring real_num_rx_queues
  virtio_net: Fix out of bounds access of sq
  virtio_net: Don't process redirected XDP frames when XDP is disabled
  virtio_net: Use xdp_return_frame to free xdp_frames on destroying vqs
  virtio_net: Differentiate sk_buff and xdp_frame on freeing
