2016-12-02Fix USB CB/CBI storage devices with CONFIG_VMAP_STACK=yPetr Vandrovec
commit 2ce9d2272b98743b911196c49e7af5841381c206 upstream. Some code (all error handling) submits CDBs that are allocated on the stack. This breaks with CB/CBI code that tries to create URB directly from SCSI command buffer - which happens to be in vmalloced memory with vmalloced kernel stacks. Let's make copy of the command in usb_stor_CB_transport.

2016-11-18usb: gadget: u_ether: remove interrupt throttlingFelipe Balbi
commit fd9afd3cbe404998d732be6cc798f749597c5114 upstream. According to Dave Miller "the networking stack has a hard requirement that all SKBs which are transmitted must have their completion signalled in a fininte amount of time. This is because, until the SKB is freed by the driver, it holds onto socket, netfilter, and other subsystem resources." In summary, this means that using TX IRQ throttling for the networking gadgets is, at least, complex and we should avoid it for the time being.

2016-10-07usb: misc: legousbtower: Fix NULL pointer deferenceGreg Kroah-Hartman
commit 2fae9e5a7babada041e2e161699ade2447a01989 upstream. This patch fixes a NULL pointer dereference caused by a race codition in the probe function of the legousbtower driver. It re-structures the probe function to only register the interface after successfully reading the board's firmware ID. The probe function does not deregister the usb interface after an error receiving the devices firmware ID. The device file registered (/dev/usb/legousbtower%d) may be read/written globally before the probe function returns. When tower_delete is called in the probe function (after an r/w has been initiated), core dev structures are deleted while the file operation functions are still running. If the 0 address is mappable on the machine, this vulnerability can be used to create a Local Priviege Escalation exploit via a write-what-where condition by remapping dev->interrupt_out_buffer in tower_write. A forged USB device and local program execution would be required for LPE. The USB device would have to delay the control message in tower_probe and accept the control urb in tower_open whilst guest code initiated a write to the device file as tower_delete is called from the error in tower_probe. This bug has existed since 2003. Patch tested by emulated device.

commit bcf42aa60c2832510b9be0f30c090bfd35bb172d upstream. The stop endpoint command has its own 5 second timeout timer. If the timeout function is triggered between USB3 and USB2 host removal it will try to call usb_hc_died(xhci_to_hcd(xhci)->primary_hcd) the ->primary_hcd will be set to NULL at USB3 hcd removal. Fix this by first checking if the PCI host is being removed, and also by using only xhci_to_hcd() as it will always return the primary hcd.

2016-09-24USB: change bInterval default to 10 msAlan Stern
commit 08c5cd37480f59ea39682f4585d92269be6b1424 upstream. Some full-speed mceusb infrared transceivers contain invalid endpoint descriptors for their interrupt endpoints, with bInterval set to 0. In the past they have worked out okay with the mceusb driver, because the driver sets the bInterval field in the descriptor to 1, overwriting whatever value may have been there before. However, this approach was never sanctioned by the USB core, and in fact it does not work with xHCI controllers, because they use the bInterval value that was present when the configuration was installed. Currently usbcore uses 32 ms as the default interval if the value in the endpoint descriptor is invalid. It turns out that these IR transceivers don't work properly unless the interval is set to 10 ms or below. To work around this mceusb problem, this patch changes the endpoint-descriptor parsing routine, making the default interval value be 10 ms rather than 32 ms.

commit 6f3c4fb6d05e63c9c6d8968302491c3a5457be61 upstream. Problems with the signal integrity of the high speed USB data lines or noise on reference ground lines can cause the i.MX6 USB controller to violate USB specs and exhibit unexpected behavior. It was observed that USBi_UI interrupts were triggered first and when isr_setup_status_phase was called, ci->status was NULL, which lead to a NULL pointer dereference kernel panic. This patch fixes the kernel panic, emits a warning once and returns -EPIPE to halt the device and let the host get stalled. It also adds a comment to point people, who are experiencing this issue, to their USB hardware design.

2016-09-24usb: renesas_usbhs: fix clearing the {BRDY,BEMP}STS conditionYoshihiro Shimoda
commit 519d8bd4b5d3d82c413eac5bb42b106bb4b9ec15 upstream. The previous driver is possible to stop the transfer wrongly. For example: 1) An interrupt happens, but not BRDY interruption. 2) Read INTSTS0. And than state->intsts0 is not set to BRDY. 3) BRDY is set to 1 here. 4) Read BRDYSTS. 5) Clear the BRDYSTS. And then. the BRDY is cleared wrongly. Remarks: - The INTSTS0.BRDY is read only. - If any bits of BRDYSTS are set to 1, the BRDY is set to 1. - If BRDYSTS is 0, the BRDY is set to 0. So, this patch adds condition to avoid such situation. (And about NRDYSTS, this is not used for now. But, avoiding any side effects, this patch doesn't touch it.)

2016-09-07USB: avoid left shift by -1Alan Stern
commit 53e5f36fbd2453ad69a3369a1db62dc06c30a4aa upstream. UBSAN complains about a left shift by -1 in proc_do_submiturb(). This can occur when an URB is submitted for a bulk or control endpoint on a high-speed device, since the code doesn't bother to check the endpoint type; normally only interrupt or isochronous endpoints have a nonzero bInterval value. Aside from the fact that the operation is illegal, it shouldn't matter because the result isn't used. Still, in theory it could cause a hardware exception or other problem, so we should work around it. This patch avoids doing the left shift unless the shift amount is >= 0. The same piece of code has another problem. When checking the device speed (the exponential encoding for interrupt endpoints is used only by high-speed or faster devices), we need to look for speed >= USB_SPEED_SUPER as well as speed == USB_SPEED HIGH. The patch adds this check.

2016-09-07xhci: always handle "Command Ring Stopped" eventsMathias Nyman
commit 33be126510974e2eb9679f1ca9bca4f67ee4c4c7 upstream. Fix "Command completion event does not match command" errors by always handling the command ring stopped events. The command ring stopped event is generated as a result of aborting or stopping the command ring with a register write. It is not caused by a command in the command queue, and thus won't have a matching command in the comman list. Solve it by handling the command ring stopped event before checking for a matching command. In most command time out cases we abort the command ring, and get a command ring stopped event. The events command pointer will point at the current command ring dequeue, which in most cases matches the timed out command in the command list, and no error messages are seen. If we instead get a command aborted event before the command ring stopped event, the abort event will increse the command ring dequeue pointer, and the following command ring stopped events command pointer will point at the next, not yet queued command. This case triggered the error message Signed-off-by: Mathias Nyman <mathias.nyman@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

In this case, the driver will cause the following message: renesas_usbhs e6590000.usb: irq_ready run_error 1 : -16 This issue causes the followings: 1) A pipe is enabled as transmission 2) The pipe sent a data 3) The pipe is disabled and re-enabled as reception. 4) The pipe got a queue Since the driver doesn't clear the BRDYSTS flags after 2) above, the issue happens.
