hv_netvsc: Fix unwanted rx_table reset

2019-12-21T05:50:38Z

In existing code, the receive indirection table, rx_table, is in struct rndis_device, which will be reset when changing MTU, ringparam, etc. User configured receive indirection table values will be lost. To fix this, move rx_table to struct net_device_context, and check netif_is_rxfh_configured(), so rx_table will be set to default only if no user configured value.

hv_netvsc: Fix tx_table init in rndis_set_subchannel()

2019-12-14T19:27:30Z

Host can provide send indirection table messages anytime after RSS is enabled by calling rndis_filter_set_rss_param(). So the host provided table values may be overwritten by the initialization in rndis_set_subchannel(). To prevent this problem, move the tx_table initialization before calling rndis_filter_set_rss_param().

treewide: Use sizeof_field() macro

hv_netvsc: Fix send_table offset in case of a host bug

2019-11-22T03:32:23Z

If negotiated NVSP version <= NVSP_PROTOCOL_VERSION_6, the offset may be wrong (too small) due to a host bug. This can cause missing the end of the send indirection table, and add multiple zero entries from leading zeros before the data region. This bug adds extra burden on channel 0. So fix the offset by computing it from the data structure sizes. This will ensure netvsc driver runs normally on unfixed hosts, and future fixed hosts.

hv_netvsc: Fix offset usage in netvsc_send_table()

2019-11-22T03:32:23Z

To reach the data region, the existing code adds offset in struct nvsp_5_send_indirect_table on the beginning of this struct. But the offset should be based on the beginning of its container, struct nvsp_message. This bug causes the first table entry missing, and adds an extra zero from the zero pad after the data region. This can put extra burden on the channel 0. So, correct the offset usage. Also add a boundary check to ensure not reading beyond data region.
