USB: fix out-of-bounds in usb_set_configuration

2017-10-12T09:51:17+00:00

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: hub: fix SS max number of ports

2017-06-24T05:11:15+00:00

commit 93491ced3c87c94b12220dbac0527e1356702179 upstream. Add define for the maximum number of ports on a SuperSpeed hub as per USB 3.1 spec Table 10-5, and use it when verifying the retrieved hub descriptor. This specifically avoids benign attempts to update the DeviceRemovable mask for non-existing ports (should we get that far).

usb: gadget: f_fs: handle control requests not directed to interface or endpoint

2016-08-25T09:13:17+00:00

Introduces a new FunctionFS descriptor flag named FUNCTIONFS_ALL_CTRL_RECIP. When this flag is enabled, control requests, which are not explicitly directed to an interface or endpoint, can be handled. This allows FunctionFS userspace drivers to process non-standard control requests. Signed-off-by: Felix Hädicke Signed-off-by: Felipe Balbi

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

2016-03-04T13:14:22+00:00

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.
