[PATCH V2] usb: hub: Fix unbalanced reference count/memory leak/deadlocks

by Viresh Kumar

Memory leak and unbalanced reference count: If the hub gets disconnected while the core is still activating it, this can result in leaking memory of few USB structures. This will happen if we have done a kref_get() from hub_activate() and scheduled a delayed work item for HUB_INIT2/3. Now if hub_disconnect() gets called before the delayed work expires, then we will cancel the work from hub_quiesce(), but wouldn't do a kref_put(). And so the unbalance. kmemleak reports this as (with the commit e50293ef9775 backported to 3.10 kernel with other changes, though the same is true for mainline as well): unreferenced object 0xffffffc08af5b800 (size 1024): comm "khubd", pid 73, jiffies 4295051211 (age 6482.350s) hex dump (first 32 bytes): 30 68 f3 8c c0 ff ff ff 00 a0 b2 2e c0 ff ff ff 0h.............. 01 00 00 00 00 00 00 00 00 94 7d 40 c0 ff ff ff ..........}@.... backtrace: [<ffffffc0003079ec>] create_object+0x148/0x2a0 [<ffffffc000cc150c>] kmemleak_alloc+0x80/0xbc [<ffffffc000303a7c>] kmem_cache_alloc_trace+0x120/0x1ac [<ffffffc0006fa610>] hub_probe+0x120/0xb84 [<ffffffc000702b20>] usb_probe_interface+0x1ec/0x298 [<ffffffc0005d50cc>] driver_probe_device+0x160/0x374 [<ffffffc0005d5308>] __device_attach+0x28/0x4c [<ffffffc0005d3164>] bus_for_each_drv+0x78/0xac [<ffffffc0005d4ee0>] device_attach+0x6c/0x9c [<ffffffc0005d42b8>] bus_probe_device+0x28/0xa0 [<ffffffc0005d23a4>] device_add+0x324/0x604 [<ffffffc000700fcc>] usb_set_configuration+0x660/0x6cc [<ffffffc00070a350>] generic_probe+0x44/0x84 [<ffffffc000702914>] usb_probe_device+0x54/0x74 [<ffffffc0005d50cc>] driver_probe_device+0x160/0x374 [<ffffffc0005d5308>] __device_attach+0x28/0x4c Deadlocks: If the hub gets disconnected early enough (i.e. before INIT2/INIT3 are finished and the init_work is still queued), the core may call hub_quiesce() after acquiring interface device locks and it will wait for the work to be cancelled synchronously. But if the work handler is already running in parallel, it may try to acquire the same interface device lock and this may result in deadlock. Fix both the issues by removing the call to cancel_delayed_work_sync().
