Revision 71f21959dd5516031db4f011e15e9a9508b93a7d authored by Haiyang Zhang on 21 November 2019, 21:33:40 UTC, committed by David S. Miller on 22 November 2019, 03:32:23 UTC
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.
Fixes: 5b54dac856cb ("hyperv: Add support for virtual Receive Side Scaling (vRSS)")
