2021-05-28i2c: s3c2410: fix possible NULL pointer deref on read message after writeKrzysztof Kozlowski
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.

2021-05-28i2c: mediatek: Disable i2c start_en and clear intr_stat brfore resetQii Wang
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.

2021-05-27i2c: i801: Don't generate an interrupt on bus resetJean Delvare
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.

2021-05-27drm/tegra: sor: Fix AUX device reference leakThierry Reding
In the case where the AUX provides an I2C-over-AUX DDC channel, a reference is taken on the AUX parent device of the DDC channel rather than the DDC channel like it would be for regular I2C controllers. To make sure the correct reference is dropped, move the unreferencing code into the SOR driver and make sure not to drop the I2C adapter reference in that case.

2021-05-27drm/tegra: Get ref for DP AUX channel, not its ddc adapterLyude Paul
While we're taking a reference of the DDC adapter for a DP AUX channel in tegra_sor_probe() because we're going to be using that adapter with the SOR, now that we've moved where AUX registration happens the actual device structure for the DDC adapter isn't initialized yet. Which means that we can't really take a reference from it to try to keep it around anymore. This should be fine though, because we can just take a reference of its parent instead. v2: * Avoid calling i2c_put_adapter() in tegra_output_remove() for eDP/DP cases Signed-off-by: Lyude Paul <lyude@redhat.com> Fixes: 39c17ae60ea9 ("drm/tegra: Don't register DP AUX channels before connectors") Cc: Lyude Paul <lyude@redhat.com> Cc: Thierry Reding <thierry.reding@gmail.com> Cc: Jonathan Hunter <jonathanh@nvidia.com> Cc: dri-devel@lists.freedesktop.org Cc: linux-tegra@vger.kernel.org Signed-off-by: Thierry Reding <treding@nvidia.com>

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.
