netvsc: fix calculation of available send sections

2017-04-25T15:56:59Z

My change (introduced in 4.11) to use find_first_clear_bit incorrectly assumed that the size argument was words, not bits. The effect was only a small limited number of the available send sections were being actually used. This can cause performance loss with some workloads. Since map_words is now used only during initialization, it can be on stack instead of in per-device data.

netvsc: fix race during initialization

2017-03-17T04:35:33Z

When device is being setup on boot, there is a small race where network device callback is registered, but the netvsc_device pointer is not set yet. This can cause a NULL ptr dereference if packet arrives during this window.

netvsc: handle select_queue when device is being removed

2017-03-13T06:13:41Z

Move the send indirection table from the inner device (netvsc) to the network device context. It is possible that netvsc_device is not present (remove in progress). This solves potential use after free issues when packet is being created during MTU change, shutdown, or queue count changes.

netvsc: fix use-after-free in netvsc_change_mtu()

2017-03-02T22:41:36Z

'nvdev' is freed in rndis_filter_device_remove -> netvsc_device_remove -> free_netvsc_device, so we mustn't access it, before it's re-created in rndis_filter_device_add -> netvsc_device_add.
