usb: core: get config and string descriptors for unauthorized devices

2014-02-06T19:05:48+00:00

commit 83e83ecb79a8225e79bc8e54e9aff3e0e27658a2 upstream. There is no need to skip querying the config and string descriptors for unauthorized WUSB devices when usb_new_device is called. It is allowed by WUSB spec. The only action that needs to be delayed until authorization time is the set config. This change allows user mode tools to see the config and string descriptors earlier in enumeration which is needed for some WUSB devices to function properly on Android systems. It also reduces the amount of divergent code paths needed for WUSB devices. Signed-off-by: Thomas Pugliese Signed-off-by: Greg Kroah-Hartman

usb: config->desc.bLength may not exceed amount of data returned by the device

2013-09-27T00:15:32+00:00

commit b4f17a488ae2e09bfcf95c0e0b4219c246f1116a upstream. While reading the config parsing code I noticed this check is missing, without this check config->desc.wTotalLength can end up with a value larger then the dev->rawdescriptors length for the config, and when userspace then tries to get the rawdescriptors bad things may happen.

usbcore: get BOS descriptor set

2011-09-26T22:51:08+00:00

This commit gets BOS(Binary Device Object Store) descriptor set for Super Speed devices and High Speed devices which support BOS descriptor. BOS descriptor is used to report additional USB device-level capabilities that are not reported via the Device descriptor. By getting BOS descriptor set, driver can check device's device-level capability such as LPM capability. Signed-off-by: Andiry Xu Signed-off-by: Sarah Sharp Signed-off-by: Greg Kroah-Hartman

USB: use usb_endpoint_maxp() instead of le16_to_cpu()

2011-08-23T16:47:40+00:00

Now ${LINUX}/drivers/usb/* can use usb_endpoint_maxp(desc) to get maximum packet size instead of le16_to_cpu(desc->wMaxPacketSize).

usb/config: use proper endian access for wMaxPacketSize

2011-08-01T16:45:29+00:00

wMaxPacketSize is __le16 and should be accessed as such. Also fix the wBytesPerInterval assignment while here. v2: also fix the wBytesPerInterval assigment, noticed by Matt Evans This patch should be backported to the 3.0 kernel.

usb/ch9: use proper endianess for wBytesPerInterval

2011-05-02T23:42:51+00:00

while going through Tatyana's changes for the gadget framework I noticed that this type is not defined as __le16. Signed-off-by: Sebastian Andrzej Siewior Signed-off-by: Sarah Sharp

USB: remove the usb_host_ss_ep_comp structure

2010-05-20T20:21:40+00:00

This patch (as1375) eliminates the usb_host_ss_ep_comp structure used for storing a dynamically-allocated copy of the SuperSpeed endpoint companion descriptor. The SuperSpeed descriptor is placed directly in the usb_host_endpoint structure, alongside the standard endpoint descriptor.

USB: core: config.c: usb_get_configuration() simplified

2010-05-20T20:21:39+00:00

usb_gat_configuratio() used two pointers to point to the same memory. Code simplified, by removing one of them. Signed-off-by: Michal Nazarewicz Cc: Alan Stern Signed-off-by: Greg Kroah-Hartman

USB: Add a new quirk: USB_QUIRK_HONOR_BNUMINTERFACES

2010-05-20T20:21:32+00:00

Add a new quirk USB_QUIRK_HONOR_BNUMINTERFACES, when this quirk is set and a device has more interface descriptors in a configuration then it claims to have in config->bNumInterfaces, ignore all additional interfaces. This is needed for devices which try to hide unused interfaces by only lowering config->bNumInterfaces, and which can't handle if you try to talk to the "hidden" interfaces.

USB: make hcd.h public (drivers dependency)

2010-05-20T20:21:30+00:00

The usbcore headers: hcd.h and hub.h are shared between usbcore, HCDs and a couple of other drivers (e.g. USBIP modules). So, it makes sense to move them into a more public location and to cleanup dependency of those modules on kernel internal headers. This patch moves hcd.h from drivers/usb/core into include/linux/usb/ Signed-of-by: Eric Lescouet Cc: Alan Stern Signed-off-by: Greg Kroah-Hartman
