USB: misc: iowarrior: add support for the 100 device

2020-02-28T15:38:45+00:00

commit bab5417f5f0118ce914bc5b2f8381e959e891155 upstream. Add a new device id for the 100 devie. It has 4 interfaces like the 28 and 28L devices but a larger endpoint so more I/O pins.

USB: misc: iowarrior: add support for the 28 and 28L devices

2020-02-28T15:38:44+00:00

commit 5f6f8da2d7b5a431d3f391d0d73ace8edfb42af7 upstream. Add new device ids for the 28 and 28L devices. These have 4 interfaces instead of 2, but the driver binds the same, so the driver changes are minimal.

USB: misc: iowarrior: add support for 2 OEMed devices

2020-02-28T15:38:44+00:00

commit 461d8deb26a7d70254bc0391feb4fd8a95e674e8 upstream. Add support for two OEM devices that are identical to existing IO-Warrior devices, except for the USB device id.

USB: adutux: fix interface sanity check

2019-12-17T19:34:40+00:00

commit 3c11c4bed02b202e278c0f5c319ae435d7fb9815 upstream. Make sure to use the current alternate setting when verifying the interface descriptors to avoid binding to an invalid interface. Failing to do so could cause the driver to misbehave or trigger a WARN() in usb_submit_urb() that kernels with panic_on_warn set would choke on.

appledisplay: fix error handling in the scheduled work

2019-12-01T08:17:42+00:00

commit 91feb01596e5efc0cc922cc73f5583114dccf4d2 upstream. The work item can operate on 1. stale memory left over from the last transfer the actual length of the data transfered needs to be checked 2. memory already freed the error handling in appledisplay_probe() needs to cancel the work in that case Reported-and-tested-by: syzbot+495dab1f175edc9c2f13@syzkaller.appspotmail.com Signed-off-by: Oliver Neukum Cc: stable Link: https://lore.kernel.org/r/20191106124902.7765-1-oneukum@suse.com Signed-off-by: Greg Kroah-Hartman

USB: chaoskey: fix error case of a timeout

2019-12-01T08:17:41+00:00

commit 92aa5986f4f7b5a8bf282ca0f50967f4326559f5 upstream. In case of a timeout or if a signal aborts a read communication with the device needs to be ended lest we overwrite an active URB the next time we do IO to the device, as the URB may still be active.

USB: misc: appledisplay: fix backlight update_status return code

2019-12-01T08:16:37+00:00

[ Upstream commit 090158555ff8d194a98616034100b16697dd80d0 ] Upon success the update_status handler returns a positive number corresponding to the number of bytes transferred by usb_control_msg. However the return code of the update_status handler should indicate if an error occurred(negative) or how many bytes of the user's input to sysfs that was consumed. Return code zero indicates all bytes were consumed. The bug can for example result in the update_status handler being called twice, the second time with only the "unconsumed" part of the user's input to sysfs. Effectively setting an incorrect brightness. Change the update_status handler to return zero for all successful transactions and forward usb_control_msg's error code upon failure.

USB: ldusb: use unsigned size format specifiers

2019-11-12T18:21:08+00:00

[ Upstream commit 88f6bf3846ee90bf33aa1ce848cd3bfb3229f4a4 ] A recent info-leak bug manifested itself along with warning about a negative buffer overflow: ldusb 1-1:0.28: Read buffer overflow, -131383859965943 bytes dropped when it was really a rather large positive one. A sanity check that prevents this has now been put in place, but let's fix up the size format specifiers, which should all be unsigned.

USB: ldusb: fix control-message timeout

commit 52403cfbc635d28195167618690595013776ebde upstream. USB control-message timeouts are specified in milliseconds, not jiffies. Waiting 83 minutes for a transfer to complete is a bit excessive.
