usb: add helper to extract bits 12:11 of wMaxPacketSize

2017-12-20T09:07:16Z

commit 541b6fe63023f3059cf85d47ff2767a3e42a8e44 upstream. According to USB Specification 2.0 table 9-4, wMaxPacketSize is a bitfield. Endpoint's maxpacket is laid out in bits 10:0. For high-speed, high-bandwidth isochronous endpoints, bits 12:11 contain a multiplier to tell us how many transactions we want to try per uframe. This means that if we want an isochronous endpoint to issue 3 transfers of 1024 bytes per uframe, wMaxPacketSize should contain the value: 1024 | (2 << 11) or 5120 (0x1400). In order to make Host and Peripheral controller drivers' life easier, we're adding a helper which returns bits 12:11. Note that no care is made WRT to checking endpoint type and gadget's speed. That's left for drivers to handle. Signed-off-by: Felipe Balbi Signed-off-by: Greg Kroah-Hartman

USB: core: Add type-specific length check of BOS descriptors

2017-12-09T21:01:56Z

commit 81cf4a45360f70528f1f64ba018d61cb5767249a upstream. As most of BOS descriptors are longer in length than their header 'struct usb_dev_cap_header', comparing solely with it is not sufficient to avoid out-of-bounds access to BOS descriptors. This patch adds descriptor type specific length check in usb_get_bos_descriptor() to fix the issue. Signed-off-by: Masakazu Mokuno Signed-off-by: Greg Kroah-Hartman

USB: fix out-of-bounds in usb_set_configuration

2017-10-12T09:51:17Z

commit bd7a3fe770ebd8391d1c7d072ff88e9e76d063eb upstream. Andrey Konovalov reported a possible out-of-bounds problem for a USB interface association descriptor. He writes: It seems there's no proper size check of a USB_DT_INTERFACE_ASSOCIATION descriptor. It's only checked that the size is >= 2 in usb_parse_configuration(), so find_iad() might do out-of-bounds access to intf_assoc->bInterfaceCount. And he's right, we don't check for crazy descriptors of this type very well, so resolve this problem. Yet another issue found by syzkaller...

usb: ch9: Add size macro for SSP dev cap descriptor

2016-03-04T13:14:22Z

The SuperspeedPlus Device Capability Descriptor has a variable size depending on the number of sublink speed attributes. This patch adds a macro to calculate that size. The macro takes one argument, the Sublink Speed Attribute Count (SSAC) as reported by the descriptor in bmAttributes[4:0]. See USB 3.1 9.6.2.5, Table 9-19.
