| * HID: Add Support for Setting and Getting Feature Reports from hidrawAlan Ott2011-02-111-0/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Per the HID Specification, Feature reports must be sent and received on the Configuration endpoint (EP 0) through the Set_Report/Get_Report interfaces. This patch adds two ioctls to hidraw to set and get feature reports to and from the device. Modifications were made to hidraw and usbhid. New hidraw ioctls: HIDIOCSFEATURE - Perform a Set_Report transfer of a Feature report. HIDIOCGFEATURE - Perform a Get_Report transfer of a Feature report.

* | kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERTDavid Rientjes2011-01-211-1/+1
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option is used to configure any non-standard kernel with a much larger scope than only small devices. This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes references to the option throughout the kernel. A new CONFIG_EMBEDDED option is added that automatically selects CONFIG_EXPERT when enabled and can be used in the future to isolate options that should only be considered for embedded systems (RISC architectures, SLOB, etc). Calling the option "EXPERT" more accurately represents its intention: only expert users who understand the impact of the configuration changes they are making should enable it.

* | HID: Consolidate device existence checks in hiddev_ioctlValentine Barshak2010-12-071-184/+103
| | | | | | | | | | | | | | | | | | | | | | | | 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.

* | HID: Fix race between disconnect and hiddev_ioctlValentine Barshak2010-12-071-37/+131
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | * | | HID: don't Send Feature Reports on Interrupt EndpointAlan Ott2010-09-221-1/+1
| | |/ / / | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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>

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) { <+...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit bd25f4dd6972755579d0 ("HID: hiddev: use usb_find_interface, get rid of BKL") introduced using of private intfdata in hiddev for purpose of storing hiddev pointer. This is a problem, because intf pointer is already being set to struct hid_device pointer by HID core. This obviously lead to memory corruptions at device disconnect time, such as WARNING: at lib/kobject.c:595 kobject_put+0x37/0x4b() kobject: '(null)' (ffff88011e9cd898): is not initialized, yet kobject_put() is being called. Convert hiddev into accessing hiddev through struct hid_device which is in intfdata already.

|/ | | | | | | | | | | | | | | | One of our users reports consistently hitting a NULL dereference that resolves to the "hid_to_usb_dev(hid);" call in hiddev_ioctl(), when disconnecting a Lego WeDo USB HID device from an OLPC XO running Scratch software. There's a FIXME comment and a guard against the dereference, but that happens farther down the function than the initial dereference does. This patch moves the call to be below the guard, and the user reports that it fixes the problem for him.

| * HID: hiddev: use usb_find_interface, get rid of BKLArnd Bergmann2010-07-131-42/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This removes the private hiddev_table in the usbhid driver and changes it to use usb_find_interface instead. The advantage is that we can avoid the race between usb_register_dev and usb_open and no longer need the big kernel lock. This doesn't introduce race condition -- the intf pointer could be invalidated only in hiddev_disconnect() through usb_deregister_dev(), but that will block on minor_rwsem and not actually remove the device until usb_open().
