2021-06-25HID: thrustmaster: Switch to kmemdup() when allocate change_requestYang Yingliang1-2/+3

2021-06-24HID: input: Add support for Programmable ButtonsThomas Weißschuh2-0/+33
Map them to KEY_MACRO# event codes. These buttons are defined by HID as follows: "The user defines the function of these buttons to control software applications or GUI objects." This matches the semantics of the KEY_MACRO# input event codes that Linux supports. Also add support for HID "Named Array" collections. Also add hid-debug support for KEY_MACRO#.

2021-06-15HID: surface-hid: Fix get-report requestMaximilian Luz1-1/+1
Getting a report (e.g. feature report) from a device requires us to send a request indicating which report we want to retrieve and then waiting for the corresponding response containing that report. We already provide the response structure to the request call, but the request isn't marked as a request that expects a response. Thus the request returns before we receive the response and the response buffer indicates a zero length response due to that. This essentially means that the get-report calls are broken and will always indicate that a report of length zero has been read. Fix this by appropriately marking the request.

2021-06-15HID: sony: fix freeze when inserting ghlive ps3/wii donglesPascal Giard1-49/+49
This commit fixes a freeze on insertion of a Guitar Hero Live PS3/WiiU USB dongle. Indeed, with the current implementation, inserting one of those USB dongles will lead to a hard freeze. I apologize for not catching this earlier, it didn't occur on my old laptop. While the issue was isolated to memory alloc/free, I could not figure out why it causes a freeze. So this patch fixes this issue by simplifying memory allocation and usage. We remind that for the dongle to work properly, a control URB needs to be sent periodically. We used to alloc/free the URB each time this URB needed to be sent. With this patch, the memory for the URB is allocated on the probe, reused for as long as the dongle is plugged in, and freed once the dongle is unplugged.

2021-05-28i2c: s3c2410: fix possible NULL pointer deref on read message after writeKrzysztof Kozlowski1-0/+3
Interrupt handler processes multiple message write requests one after another, till the driver message queue is drained. However if driver encounters a read message without preceding START, it stops the I2C transfer as it is an invalid condition for the controller. At least the comment describes a requirement "the controller forces us to send a new START when we change direction". This stop results in clearing the message queue (i2c->msg = NULL). The code however immediately jumped back to label "retry_write" which dereferenced the "i2c->msg" making it a possible NULL pointer dereference. The Coverity analysis: 1. Condition !is_msgend(i2c), taking false branch. if (!is_msgend(i2c)) { 2. Condition !is_lastmsg(i2c), taking true branch. } else if (!is_lastmsg(i2c)) { 3. Condition i2c->msg->flags & 1, taking true branch. if (i2c->msg->flags & I2C_M_RD) { 4. write_zero_model: Passing i2c to s3c24xx_i2c_stop, which sets i2c->msg to NULL. s3c24xx_i2c_stop(i2c, -EINVAL); 5. Jumping to label retry_write. goto retry_write; 6. var_deref_model: Passing i2c to is_msgend, which dereferences null i2c->msg. if (!is_msgend(i2c)) {" All previous calls to s3c24xx_i2c_stop() in this interrupt service routine are followed by jumping to end of function (acknowledging the interrupt and returning). This seems a reasonable choice also here since message buffer was entirely emptied.

The i2c controller driver do dma reset after transfer timeout, but sometimes dma reset will trigger an unexpected DMA_ERR irq. It will cause the i2c controller to continuously send interrupts to the system and cause soft lock-up. So we need to disable i2c start_en and clear intr_stat to stop i2c controller before dma reset when transfer timeout.

This allows only the proper fix to go to stable@ (since the original fix was successfully dropped). * tag 'for-5.13/dm-fixes-2' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm: dm snapshot: properly fix a crash when an origin has no snapshots dm snapshot: revert "fix a crash when an origin has no snapshots" dm verity: fix require_signatures module_param permissions
2021-05-27i2c: i801: Don't generate an interrupt on bus resetJean Delvare1-4/+2
Now that the i2c-i801 driver supports interrupts, setting the KILL bit in a attempt to recover from a timed out transaction triggers an interrupt. Unfortunately, the interrupt handler (i801_isr) is not prepared for this situation and will try to process the interrupt as if it was signaling the end of a successful transaction. In the case of a block transaction, this can result in an out-of-range memory access. This condition was reproduced several times by syzbot: https://syzkaller.appspot.com/bug?extid=ed71512d469895b5b34e https://syzkaller.appspot.com/bug?extid=8c8dedc0ba9e03f6c79e https://syzkaller.appspot.com/bug?extid=c8ff0b6d6c73d81b610e https://syzkaller.appspot.com/bug?extid=33f6c360821c399d69eb https://syzkaller.appspot.com/bug?extid=be15dc0b1933f04b043a https://syzkaller.appspot.com/bug?extid=b4d3fd1dfd53e90afd79 So disable interrupts while trying to reset the bus. Interrupts will be enabled again for the following transaction.

There is no need to use a quirk and then return -ENODEV from the asus_probe() function to avoid that hid-asus binds to the hiddev for the USB-interface for the hid-multitouch touchpad. The hid-multitouch hiddev has a group of HID_GROUP_MULTITOUCH_WIN_8, so the same result can be achieved by making the hid_device_id entry for the dock in the asus_devices[] table only match on HID_GROUP_GENERIC instead of having it match HID_GROUP_ANY.

This means that the remove callback will dereference the never-initialised driver data pointer when the driver is later unbound (e.g. on USB disconnect).
