commit ac8616e4 upstream. The MP style clocks support an mux with pre-dividers. While the driver correctly accounted for them in the .determine_rate callback, it did not in the .recalc_rate and .set_rate callbacks. This means when calculating the factors in the .set_rate callback, they would be off by a factor of the active pre-divider. Same goes for reading back the clock rate after it is set.

commit 8c75704e upstream. After commit e9afc746 ("hwrng: geode - Use linux/io.h instead of asm/io.h") the geode-rng driver uses devres with pci_dev->dev to keep track of resources, but does not actually register a PCI driver. This results in the following issues: 1. The driver leaks memory because the driver does not attach to a device. The driver only uses the PCI device as a reference. devm_*() functions will release resources on driver detach, which the geode-rng driver will never do. As a result, 2. The driver cannot be reloaded because there is always a use of the ioport and region after the first load of the driver.

commit 69db7009 upstream. After commit 31b2a73c ("hwrng: amd - Migrate to managed API"), the amd-rng driver uses devres with pci_dev->dev to keep track of resources, but does not actually register a PCI driver. This results in the following issues: 1. The message WARNING: CPU: 2 PID: 621 at drivers/base/dd.c:349 driver_probe_device+0x38c is output when the i2c_amd756 driver loads and attempts to register a PCI driver. The PCI & device subsystems assume that no resources have been registered for the device, and the WARN_ON() triggers since amd-rng has already do so. 2. The driver leaks memory because the driver does not attach to a device. The driver only uses the PCI device as a reference. devm_*() functions will release resources on driver detach, which the amd-rng driver will never do. As a result, 3. The driver cannot be reloaded because there is always a use of the ioport and region after the first load of the driver. Revert the changes made by 31b2a73c ("hwrng: amd - Migrate to managed API").

commit 027fb89e upstream. Disabling interrupts for even a millisecond can cause problems for some devices. That can happen when Intel host controllers wait for the present state to propagate. The spin lock is not necessary here. Anything that is racing with changes to the I/O state is already broken. The mmc core already provides synchronization via "claiming" the host. Although the spin lock probably should be removed from the code paths that lead to this point, such a patch would touch too much code to be suitable for stable trees. Consequently, for this patch, just drop the spin lock while waiting. Signed-off-by:

commit 16681037 upstream. sdhci_arasan_get_timeout_clock() divides the frequency it has with (1 << (13 + divisor)). However, the divisor is not some Arasan-specific value, but instead is just the Data Timeout Counter Value from the SDHCI Timeout Control Register. Applying it here like this is wrong as the sdhci driver already takes that value into account when calculating timeouts, and in fact it *sets* that register value based on how long a timeout is wanted. Additionally, sdhci core interprets the .get_timeout_clock callback return value as if it were read from hardware registers, i.e. the unit should be kHz or MHz depending on SDHCI_TIMEOUT_CLK_UNIT capability bit. This bit is set at least on the tested Zynq-7000 SoC. With the tested hardware (SDHCI_TIMEOUT_CLK_UNIT set) this results in too high a timeout clock rate being reported, causing the core to use longer-than-needed timeouts. Additionally, on a partitioned MMC (therefore having erase_group_def bit set) mmc_calc_max_discard() disables discard support as it looks like controller does not support the long timeouts needed for that. Do not apply the extra divisor and return the timeout clock in the expected unit. Tested with a Zynq-7000 SoC and a partitioned Toshiba THGBMAG5A1JBAWR eMMC card. Signed-off-by:

Romain Izard authored
commit 2ce0c7b6 upstream. The SDHCI controller in the SAMA5D2 chip requires a valid voltage set in the power control register, otherwise commands will fail with a timeout error. When using the regulator framework to specify the regulator used by the mmc device, the voltage is not configured, and it is not possible to use the connected device. Implement a custom 'set_power' function for this specific hardware, that configures the voltage in the register in all cases. Signed-off-by:

commit 6d98ce0b upstream. We concluded there may be a window where the idle wakeup code could get to pnv_wakeup_tb_loss() (which clobbers non-volatile GPRs), but the hardware may set SRR1[46:47] to 01b (no state loss) which would result in the wakeup code failing to restore non-volatile GPRs. I was not able to trigger this condition with trivial tests on real hardware or simulator, but the ISA (at least 2.07) seems to allow for it, and Gautham says that it can happen if there is an exception pending when the sleep/winkle instruction is executed.

commit b9cf625d upstream. If ext4_convert_inline_data() was called on a directory with inline data, the filesystem was left in an inconsistent state (as considered by e2fsck) because the file size was not increased to cover the new block. This happened because the inode was not marked dirty after i_disksize was updated. Fix this by marking the inode dirty at the end of ext4_finish_convert_inline_dir(). This bug was probably not noticed before because most users mark the inode dirty afterwards for other reasons. But if userspace executed FS_IOC_SET_ENCRYPTION_POLICY with invalid parameters, as exercised by 'kvm-xfstests -c adv generic/396', then the inode was never marked dirty after updating i_disksize.

commit 03270c6a upstream. Usually every parallel port will have a single pardev registered with it. But ppdev driver is an exception. This userspace parallel port driver allows to create multiple parrallel port devices for a single parallel port. And as a result we were having a nice warning like: "sysctl table check failed: /dev/parport/parport0/devices/ppdev0/timeslice Sysctl already exists" Use the same logic as used in parport_register_device() and register the proc files only once for each parallel port.

iio: hid-sensor-trigger: Change get poll value function order to avoid sensor properties losing after resume from S3 commit 3bec2474 upstream. In function _hid_sensor_power_state(), when hid_sensor_read_poll_value() is called, sensor's all properties will be updated by the value from sensor hardware/firmware. In some implementation, sensor hardware/firmware will do a power cycle during S3. In this case, after resume, once hid_sensor_read_poll_value() is called, sensor's all properties which are kept by driver during S3 will be changed to default value. But instead, if a set feature function is called first, sensor hardware/firmware will be recovered to the last status. So change the sensor_hub_set_feature() calling order to behind of set feature function to avoid sensor properties lose. Signed-off-by:

commit e83bb3e6 upstream. The tiadc_irq_h(int irq, void *private) function is handling FIFO overruns by clearing flags, disabling and enabling the ADC to recover. If the ADC is running in continuous mode a FIFO overrun happens regularly. If the disabling of the ADC happens concurrently with a new conversion. It might happen that the enabling of the ADC is ignored by the hardware. This stops the ADC permanently. No more interrupts are triggered. According to the AM335x Reference Manual (SPRUH73H October 2011 - Revised April 2013 - Chapter 12.4 and 12.5) it is necessary to check the ADC FSM bits in REG_ADCFSM before enabling the ADC again. Because the disabling of the ADC is done right after the current conversion has been finished. To trigger this bug it is necessary to run the ADC in continuous mode. The ADC values of all channels need to be read in an endless loop. The bug appears within the first 6 hours (~5.4 million handled FIFO overruns). The user space application will hang on reading new values from the character device. Fixes: ca9a5638 ("iio: ti_am335x_adc: Add continuous sampling support") Signed-off-by:

commit 687e0687 upstream. USBTMC devices are required to have a bulk-in and a bulk-out endpoint, but the driver failed to verify this, something which could lead to the endpoint addresses being taken from uninitialised memory. Make sure to zero all private data as part of allocation, and add the missing endpoint sanity check. Note that this also addresses a more recently introduced issue, where the interrupt-in-presence flag would also be uninitialised whenever the optional interrupt-in endpoint is not present. This in turn could lead to an interrupt urb being allocated, initialised and submitted based on uninitialised values.

commit 3243367b upstream. Some USB 2.0 devices erroneously report millisecond values in bInterval. The generic config code manages to catch most of them, but in some cases it's not completely enough. The case at stake here is a USB 2.0 braille device, which wants to announce 10ms and thus sets bInterval to 10, but with the USB 2.0 computation that yields to 64ms. It happens that one can type fast enough to reach this interval and get the device buffers overflown, leading to problematic latencies. The generic config code does not catch this case because the 64ms is considered a sane enough value. This change thus adds a USB_QUIRK_LINEAR_FRAME_INTR_BINTERVAL quirk to mark devices which actually report milliseconds in bInterval, and marks Vario Ultra devices as needing it. Signed-off-by:

commit c520ff3d upstream. When snd_seq_pool_done() is called, it marks the closing flag to refuse the further cell insertions. But snd_seq_pool_done() itself doesn't clear the cells but just waits until all cells are cleared by the caller side. That is, it's racy, and this leads to the endless stall as syzkaller spotted. This patch addresses the racy by splitting the setup of pool->closing flag out of snd_seq_pool_done(), and calling it properly before snd_seq_pool_done().
