Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
RDMA/bnxt_re: Avoid CPU lockups due fifo occupancy check loop<br />
<br />
Driver waits indefinitely for the fifo occupancy to go below a threshold<br />
as soon as the pacing interrupt is received. This can cause soft lockup on<br />
one of the processors, if the rate of DB is very high.<br />
<br />
Add a loop count for FPGA and exit the __wait_for_fifo_occupancy_below_th<br />
if the loop is taking more time. Pacing will be continuing until the<br />
occupancy is below the threshold. This is ensured by the checks in<br />
bnxt_re_pacing_timer_exp and further scheduling the work for pacing based<br />
on the fifo occupancy.
