In the Linux kernel, the following vulnerability has been resolved:ila: block BH in ila_output()As explained in commit 1378817486d6 ("tipc: block BHbefore using dst_cache"), net/core/dst_cache.chelpers need to be called with BH disabled.ila_output() is called from lwtunnel_output()possibly from process context, and under rcu_read_lock().We might be interrupted by a softirq, re-enter ila_output()and corrupt dst_cache data structures.Fix the race by using local_bh_disable().
