2010-12-08HID: add hid_hw_open/close/power() handlersDmitry Torokhov

2010-12-07HID: Consolidate device existence checks in hiddev_ioctlValentine Barshak
Currently, if the device has been removed before hiddev_ioctl(), the -EIO is returned. If it's removed while hiddev_ioctl() is in progress, some commands are still processed fine, others return -ENODEV. This change takes the "existancelock" before processing ioctl commands and releases it at the end. If the device has been removed, always returns -ENODEV.

2010-12-07HID: Fix race between disconnect and hiddev_ioctlValentine Barshak
A USB HID device can be disconnected at any time. If this happens right before or while hiddev_ioctl is in progress, the hiddev_ioctl tries to access invalid hiddev->hid pointer. When the hid device is disconnected, the hiddev_disconnect() ends up with a call to hid_device_release() which frees hid_device, but doesn't set the hiddev->hid pointer to NULL. If the deallocated memory region has been re-used by the kernel, this can cause a crash or memory corruption. Since disconnect can happen at any time, we can't initialize struct hid_device *hid = hiddev->hid at the beginning of ioctl and then use it. This change checks hiddev->exist flag while holding the existancelock and uses hid_device only if it exists.

It's not really dangerous in this driver, but it's against general practice and worth fixing. Wacom uses the attribute for changing the reporting speed of the tablet (and this actually requires poking the device in the background) (still I wouldn't consider it a security issue though). udev is a proper place to handle this.

2010-10-15llseek: automatically add .llseek fopArnd Bergmann
All file_operations should get a .llseek operation so we can make nonseekable_open the default for future file operations without a .llseek pointer. The three cases that we can automatically detect are no_llseek, seq_lseek and default_llseek. For cases where we can we can automatically prove that the file offset is always ignored, we use noop_llseek, which maintains the current behavior of not returning an error from a seek. New drivers should normally not use noop_llseek but instead use no_llseek and call nonseekable_open at open time. Existing drivers can be converted to do the same when the maintainer knows for certain that no user code relies on calling seek on the device file. The generated code is often incorrectly indented and right now contains comments that clarify for each added line why a specific variant was chosen. In the version that gets submitted upstream, the comments will be gone and I will manually fix the indentation, because there does not seem to be a way to do that using coccinelle. Some amount of new code is currently sitting in linux-next that should get the same modifications, which I will do at the end of the merge window. Many thanks to Julia Lawall for helping me learn to write a semantic patch that does all this. ===== begin semantic patch ===== // This adds an llseek= method to all file operations, // as a preparation for making no_llseek the default. // // The rules are // - use no_llseek explicitly if we do nonseekable_open // - use seq_lseek for sequential files // - use default_llseek if we know we access f_pos // - use noop_llseek if we know we don't access f_pos, // but we still want to allow users to call lseek // @ open1 exists @ identifier nested_open; @@ nested_open(...) { <+... nonseekable_open(...) ...+> } @ open exists@ identifier open_f; identifier i, f; identifier open1.nested_open; @@ int open_f(struct inode *i, struct file *f) { <+...

2010-10-01HID: Fix for problems with eGalax/DWAV multi-touch-screenPhilipp Merkel
This patch fixes three problems with the eGalax/DWAV multi-touch screen found in the Eee PC T101MT: 1) While there is a dedicated multitouch driver for the screen (hid-egalax.c), the MULTI_INPUT quirk is also applied, preventing the hid-egalax driver from working. This patch removes the quirk so the hid-egalax driver can handle the device correctly. 2) The x and y coordinates sent by the screen in multi-touch mode are shifted by three bits from the events sent in single-touch mode, thus the coordinates are out of range, leading to the pointer being stuck in the bottom-right corner if no additional calibration is applied (e.g. in the X evdev driver). This patch shifts the coordinates back. This does not decrease accuracy as the last three bits of the "wrong" coordinates are always 0. 3) Only multi-touch pressure events are sent, single touch emulation is missing pressure information. This patch adds single-touch ABS_PRESSURE events. Signed-off-by: Philipp Merkel <mail@philmerk.de> Acked-by: Stéphane Chatty <chatty@enac.fr> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

2010-09-22HID: don't Send Feature Reports on Interrupt EndpointAlan Ott
Feature reports should only be sent on the control endpoint. The USB HID standard is unclear and confusing on this issue. It seems to suggest that Feature reports can be sent on a HID device's Interrupt OUT endpoint. This cannot be the case because the report type is not encoded in transfers sent out the Interrput OUT endpoint. If Feature reports were sent on the Interrupt OUT endpint, they would be indistinguishable from Output reports in the case where Report IDs were not used. Further, Windows and Mac OS X do not send Feature reports out the interrupt OUT Endpoint. They will only go out the Control Endpoint. In addition, many devices simply do not hande Feature reports sent out the Interrupt OUT endpoint.

2010-09-14HID: fix hiddev's use of usb_find_interfaceGuillaume Chazarain
My macbook infrared remote control was broken by commit bd25f4dd6972755579d0ea50d1a5ace2e9b00d1a ("HID: hiddev: use usb_find_interface, get rid of BKL"). This device appears in dmesg as: apple 0003:05AC:8242.0001: hiddev0,hidraw0: USB HID v1.11 Device [Apple Computer, Inc. IR Receiver] on usb-0000:00:1d.2-1/input0 It stopped working as lircd was getting ENODEV when opening /dev/usb/hiddev0. AFAICS hiddev_driver is a dummy driver so usb_find_interface(&hiddev_driver) does not find anything. The device is associated with the usbhid driver, so let's do usb_find_interface(&hid_driver) instead. $ ls -l /sys/devices/pci0000:00/0000:00:1d.2/usb7/7-1/7-1:1.0/usb/hiddev0/device/driver lrwxrwxrwx 1 root root 0 2010-09-12 16:28 /sys/devices/pci0000:00/0000:00:1d.2/usb7/7-1/7-1:1.0/usb/hiddev0/device/driver -> ../../../../../../bus/usb/drivers/usbhid Signed-off-by: Guillaume Chazarain <guichaz@gmail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
