usb-storage: Set virt_boundary_mask to avoid SG overflows 2019-05-10T15:52:10+00:00 Alan Stern stern@rowland.harvard.edu 2019-04-15T17:19:25+00:00 c685caf6e5d896472c67b348d23936c6dc479749 commit 747668dbc061b3e62bc1982767a3a1f9815fcf0e upstream. The USB subsystem has always had an unusual requirement for its scatter-gather transfers: Each element in the scatterlist (except the last one) must have a length divisible by the bulk maxpacket size. This is a particular issue for USB mass storage, which uses SG lists created by the block layer rather than setting up its own. So far we have scraped by okay because most devices have a logical block size of 512 bytes or larger, and the bulk maxpacket sizes for USB 2 and below are all <= 512. However, USB 3 has a bulk maxpacket size of 1024. Since the xhci-hcd driver includes native SG support, this hasn't mattered much. But now people are trying to use USB-3 mass storage devices with USBIP, and the vhci-hcd driver currently does not have full SG support. The result is an overflow error, when the driver attempts to implement an SG transfer of 63 512-byte blocks as a single 3584-byte (7 blocks) transfer followed by seven 4096-byte (8 blocks) transfers. The device instead sends 31 1024-byte packets followed by a 512-byte packet, and this overruns the first SG buffer. Ideally this would be fixed by adding better SG support to vhci-hcd. But for now it appears we can work around the problem by asking the block layer to respect the maxpacket limitation, through the use of the virt_boundary_mask.

commit c2b71462d294cf517a0bc6e4fd6424d7cee5596f upstream.

The syzkaller fuzzer reported a bug in the USB hub driver which turned
out to be caused by a negative runtime-PM usage counter.  This allowed
a hub to be runtime suspended at a time when the driver did not expect
it.  The symptom is a WARNING issued because the hub's status URB is
submitted while it is already active:

	URB 0000000031fb463e submitted while active
	WARNING: CPU: 0 PID: 2917 at drivers/usb/core/urb.c:363

The negative runtime-PM usage count was caused by an unfortunate
design decision made when runtime PM was first implemented for USB.
At that time, USB class drivers were allowed to unbind from their
interfaces without balancing the usage counter (i.e., leaving it with
a positive count).  The core code would take care of setting the
counter back to 0 before allowing another driver to bind to the
interface.

Later on when runtime PM was implemented for the entire kernel, the
opposite decision was made: Drivers were required to balance their
runtime-PM get and put calls.  In order to maintain backward
compatibility, however, the USB subsystem adapted to the new
implementation by keeping an independent usage counter for each
interface and using it to automatically adjust the normal usage
counter back to 0 whenever a driver was unbound.

This approach involves duplicating information, but what is worse, it
doesn't work properly in cases where a USB class driver delays
decrementing the usage counter until after the driver's disconnect()
routine has returned and the counter has been adjusted back to 0.
Doing so would cause the usage counter to become negative.  There's
even a warning about this in the USB power management documentation!

As it happens, this is exactly what the hub driver does.  The
kick_hub_wq() routine increments the runtime-PM usage counter, and the
corresponding decrement is carried out by hub_event() in the context
of the hub_wq work-queue thread.  This work routine may sometimes run
after the driver has been unbound from its interface, and when it does
it causes the usage counter to go negative.

It is not possible for hub_disconnect() to wait for a pending
hub_event() call to finish, because hub_disconnect() is called with
the device lock held and hub_event() acquires that lock.  The only
feasible fix is to reverse the original design decision: remove the
duplicate interface-specific usage counter and require USB drivers to
balance their runtime PM gets and puts.  As far as I know, all
existing drivers currently do this.
