Summary
In the Linux kernel, the following vulnerability has been resolved:
netdevsim: use cond_resched() in nsim_dev_trap_report_work()
I am still seeing many syzbot reports hinting that syzbot
might fool nsim_dev_trap_report_work() with hundreds of ports [1]
Lets use cond_resched(), and system_unbound_wq
instead of implicit system_wq.
