  - tipc: Fix use-after-free in tipc_mon_reinit_self(). syzbot reported use-after-free of     tipc_net(net)->monitors[] in tipc_mon_reinit_self(). [0] The array is protected by RTNL, but     tipc_mon_reinit_self() iterates over it without RTNL. tipc_mon_reinit_self() is called from     tipc_net_finalize(), which is always under RTNL except for tipc_net_finalize_work(). Let's hold RTNL in     tipc_net_finalize_work(). [0]: BUG: KASAN: slab-use-after-free in __raw_spin_lock_irqsave     include/linux/spinlock_api_smp.h:110 [inline] BUG: KASAN: slab-use-after-free in
