Revision cdd97383e19d4afe29adc3376025a15ae3bab3a3 authored by Dan Carpenter on 07 December 2022, 07:06:31 UTC, committed by Jakub Kicinski on 08 December 2022, 17:09:36 UTC
In an earlier commit, I added a bounds check to prevent an out of bounds
read and a WARN(). On further discussion and consideration that check
was probably too aggressive. Instead of returning -EINVAL, a better fix
would be to just prevent the out of bounds read but continue the process.
Background: The value of "pp->rxq_def" is a number between 0-7 by default,
or even higher depending on the value of "rxq_number", which is a module
parameter. If the value is more than the number of available CPUs then
it will trigger the WARN() in cpu_max_bits_warn().
Fixes: e8b4fc13900b ("net: mvneta: Prevent out of bounds read in mvneta_config_rss()")
