syz-executor257/6000 is trying to acquire lock:

ffffffff905c9a98 (nr_node_list_lock){+...}-{3:3}, at: nr_rt_device_down+0xd3/0x810 net/netrom/nr_route.c:517

but task is already holding lock:
ffffffff905c9a38 (nr_neigh_list_lock){+...}-{3:3}, at: spin_lock_bh include/linux/spinlock.h:356 [inline]
ffffffff905c9a38 (nr_neigh_list_lock){+...}-{3:3}, at: nr_rt_device_down+0x2c/0x810 net/netrom/nr_route.c:514

which lock already depends on the new lock.


the existing dependency chain (in reverse order) is:

other info that might help us debug this:

Chain exists of:
  nr_node_list_lock --> &nr_node->node_lock --> nr_neigh_list_lock

 Possible unsafe locking scenario:

       CPU0                    CPU1
       ----                    ----
  lock(nr_neigh_list_lock);
                               lock(&nr_node->node_lock);
                               lock(nr_neigh_list_lock);
  lock(nr_node_list_lock);
