[PATCH net 0/6] gve: various XDP fixes
Posted by Joshua Washington 1 month, 2 weeks ago
This patch series includes a number of XDP-related fixes, both in the
control plane and the dataplane.

A summary of the changes:
1) fix an issue where XDP packets weren't being counted against NAPI
   budget
2) fix an issue where XSK buffers that have not been processed are
   leaked when disabling XSK pools
3) fix an XSK buffer leak when an RX error descriptor comes back from
   the hardware
4) fix a NULL dereference due to incorrect registration of XSK pools on
   queues not set up in XSK zero copy mode
5) fix a deadlock introduced by attempting to acquire the netdev lock
   after it has already been acquired
6) fix a racy NULL dereference due to DMA umapping the XSK pool before
   queues are fully stopped

Joshua Washington (6):
  gve: increment work_done for XDP and error packets
  gve: fix XSK buffer leak when rings are stopped
  gve: fix XSK buffer leak on error descriptor
  gve: don't register xsk pool on pre-existing queues in RDA mode
  gve: fix napi_disable deadlock when attempting to disable XSK pools
  gve: fix NULL dereference from premature XSK pool DMA unmap

Quite a few review bot concerns on this patch series. I will respin to
address the concerns and manually run Sashiko to hopefully catch any
other lingering issues before resubmitting.

Please beware that we have more models running in netdev,
the emailed out ones are just from Gemini.
