usb: webcam: Invalid size of Processing Unit Descriptor

2021-03-18T08:02:27+00:00

According with USB Device Class Definition for Video Device the
Processing Unit Descriptor bLength should be 12 (10 + bmControlSize),
but it has 11.

Invalid length caused that Processing Unit Descriptor Test Video form
CV tool failed. To fix this issue patch adds bmVideoStandards into
uvc_processing_unit_descriptor structure.

The bmVideoStandards field was added in UVC 1.1 and it wasn't part of
UVC 1.0a.

usb: ch9: Add USB 3.2 SSP attributes

2021-01-18T17:38:47+00:00

In preparation for USB 3.2 dual-lane support, add sublink speed
attribute macros and enum usb_ssp_rate. A USB device that operates in
SuperSpeed Plus may operate at different speed and lane count. These
additional macros and enum values help specifying that.

USB: usbtmc: Add separate USBTMC_IOCTL_GET_SRQ_STB

2020-12-28T14:50:30+00:00

This new ioctl only returns the status byte (STB) that was originally
sent by the device due to a service request (SRQ) condition.

This ioctl checks the srq_asserted bit of the associated file
descriptor. If set, the srq_asserted bit is reset and the cached
STB with original SRQ information is returned. Otherwise the ioctl
returns the error code ENOMSG.

This ioctl is useful to support non USBTMC-488 compliant devices.
Time sensitive applications can read the cached STB without incurring
the cost of an urb transaction over the bus.

USB: usbtmc: Add USBTMC_IOCTL_GET_STB

2020-12-28T14:50:30+00:00

This new ioctl reads the status byte (STB) from the device and returns
the STB unmodified to the application. The srq_asserted bit is not taken
into account and not changed.

This ioctl is useful to support non USBTMC-488 compliant devices.

include/: replace HTTP links with HTTPS ones

2020-08-12T17:57:59+00:00

Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.

USB: ch9: add "USB_" prefix in front of TEST defines

2020-06-24T13:01:24+00:00

For some reason, the TEST_ defines in the usb/ch9.h files did not have
the USB_ prefix on it, making it a bit confusing when reading the file,
as well as not the nicest thing to do in a uapi file.

So fix that up and add the USB_ prefix on to them, and fix up all
in-kernel usages.  This included deleting the duplicate copy in the
net2272.h file.

Several newer USB Device classes are not presently reported individually at
/sys/kernel/debug/usb/devices, (reported as "unk."). This patch adds the
following classes: 0fh (Personal Healthcare devices), 10h (USB Type-C combined
Audio/Video devices) 11h (USB billboard), 12h (USB Type-C Bridge). As defined
at [https://www.usb.org/defined-class-codes]

usb: raw-gadget: support stalling/halting/wedging endpoints

2020-05-14T09:30:18+00:00

Raw Gadget is currently unable to stall/halt/wedge gadget endpoints,
which is required for proper emulation of certain USB classes.

This patch adds a few more ioctls:

- USB_RAW_IOCTL_EP0_STALL allows to stall control endpoint #0 when
  there's a pending setup request for it.
- USB_RAW_IOCTL_SET/CLEAR_HALT/WEDGE allow to set/clear halt/wedge status
  on non-control non-isochronous endpoints.

usb: raw-gadget: fix gadget endpoint selection

2020-05-14T09:30:17+00:00

Currently automatic gadget endpoint selection based on required features
doesn't work. Raw Gadget tries iterating over the list of available
endpoints and finding one that has the right direction and transfer type.
Unfortunately selecting arbitrary gadget endpoints (even if they satisfy
feature requirements) doesn't work, as (depending on the UDC driver) they
might have fixed addresses, and one also needs to provide matching
endpoint addresses in the descriptors sent to the host.

The composite framework deals with this by assigning endpoint addresses
in usb_ep_autoconfig() before enumeration starts. This approach won't work
with Raw Gadget as the endpoints are supposed to be enabled after a
set_configuration/set_interface request from the host, so it's too late to
patch the endpoint descriptors that had already been sent to the host.

For Raw Gadget we take another approach. Similarly to GadgetFS, we allow
the user to make the decision as to which gadget endpoints to use.

This patch adds another Raw Gadget ioctl USB_RAW_IOCTL_EPS_INFO that
exposes information about all non-control endpoints that a currently
connected UDC has. This information includes endpoints addresses, as well
as their capabilities and limits to allow the user to choose the most
fitting gadget endpoint.

The USB_RAW_IOCTL_EP_ENABLE ioctl is updated to use the proper endpoint
validation routine usb_gadget_ep_match_desc().

These changes affect the portability of the gadgets that use Raw Gadget
when running on different UDCs. Nevertheless, as long as the user relies
on the information provided by USB_RAW_IOCTL_EPS_INFO to dynamically
choose endpoint addresses, UDC-agnostic gadgets can still be written with
Raw Gadget.
