From: Mike Marciniszyn <mike.marciniszyn@xxxxxxxxxxxxxxxxxxxx>
All other users of the dummy netdevice embed the netdev in other
structures:
init_dummy_netdev(&mal->dummy_dev);
init_dummy_netdev(ð->dummy_dev);
init_dummy_netdev(&ar->napi_dev);
init_dummy_netdev(&irq_grp->napi_ndev);
init_dummy_netdev(&wil->napi_ndev);
init_dummy_netdev(&trans_pcie->napi_dev);
init_dummy_netdev(&dev->napi_dev);
init_dummy_netdev(&bus->mux_dev);
The AIP and VNIC implementation turns that model inside out and used a
kfree() to free what appears to be a netdev struct when in reality, it is
a struct that enbodies the rx state as well as the dummy netdev used to
support napi_poll across disparate receive contexts. The relationship is
infered by the odd allocation:
const int netdev_size = sizeof(*dd->dummy_netdev) +
sizeof(struct hfi1_netdev_priv);
<snip>
dd->dummy_netdev = kcalloc_node(1, netdev_size, GFP_KERNEL, dd->node);
Correct the issue by:
- Correctly naming the alloc and free functions
- Renaming hfi1_netdev_priv to hfi1_netdev_rx
- Replacing dd dummy_netdev with a netdev_rx pointer
- Embedding the net_device in hfi1_netdev_rx
- Moving the init_dummy_netdev to the alloc routine
- Adjusting wrappers to fit the new model
