Hi all, I just want to bring attention to the syzbot bug [1]
Even though syzbot claims the bug to be in net/tipc, I feel it is in net/dst_cache.c. Please correct me if I am wrong. This bug is being triggered a lot of times by syzbot since the day it was reported. Also given that this is core networking code, I felt it was important to bring this to attention. It looks like preemption needs to be disabled before using this_cpu_ptr or maybe we would be better of using a get_cpu_var and put_cpu_var combo here.
