Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> pktgen: use cpus_read_lock() in pg_net_init()<br /> <br /> I have seen the WARN_ON(smp_processor_id() != cpu) firing<br /> in pktgen_thread_worker() during tests.<br /> <br /> We must use cpus_read_lock()/cpus_read_unlock()<br /> around the for_each_online_cpu(cpu) loop.<br /> <br /> While we are at it use WARN_ON_ONCE() to avoid a possible syslog flood.
