Vulnerability from github
In the Linux kernel, the following vulnerability has been resolved:
IB/hfi1: Fix panic with larger ipoib send_queue_size
When the ipoib send_queue_size is increased from the default the following panic happens:
RIP: 0010:hfi1_ipoib_drain_tx_ring+0x45/0xf0 [hfi1]
Code: 31 e4 eb 0f 8b 85 c8 02 00 00 41 83 c4 01 44 39 e0 76 60 8b 8d cc 02 00 00 44 89 e3 be 01 00 00 00 d3 e3 48 03 9d c0 02 00 00
The issue happens when the shift that should have been a function of the txq item size mistakenly used the ring size.
Fix by using the item size.
