2020-08-17vfio/type1: Add proper error unwind for vfio_iommu_replay()Alex Williamson
The vfio_iommu_replay() function does not currently unwind on error, yet it does pin pages, perform IOMMU mapping, and modify the vfio_dma structure to indicate IOMMU mapping. The IOMMU mappings are torn down when the domain is destroyed, but the other actions go on to cause trouble later. For example, the iommu->domain_list can be empty if we only have a non-IOMMU backed mdev attached. We don't currently check if the list is empty before getting the first entry in the list, which leads to a bogus domain pointer. If a vfio_dma entry is erroneously marked as iommu_mapped, we'll attempt to use that bogus pointer to retrieve the existing physical page addresses. This is the scenario that uncovered this issue, attempting to hot-add a vfio-pci device to a container with an existing mdev device and DMA mappings, one of which could not be pinned, causing a failure adding the new group to the existing container and setting the conditions for a subsequent attempt to explode. To resolve this, we can first check if the domain_list is empty so that we can reject replay of a bogus domain, should we ever encounter this inconsistent state again in the future. The real fix though is to add the necessary unwind support, which means cleaning up the current pinning if an IOMMU mapping fails, then walking back through the r-b tree of DMA entries, reading from the IOMMU which ranges are mapped, and unmapping and unpinning those ranges. To be able to do this, we also defer marking the DMA entry as IOMMU mapped until all entries are processed, in order to allow the unwind to know the disposition of each entry.

2020-08-17vfio-pci: Avoid recursive read-lock usageAlex Williamson
A down_read on memory_lock is held when performing read/write accesses to MMIO BAR space, including across the copy_to/from_user() callouts which may fault. If the user buffer for these copies resides in an mmap of device MMIO space, the mmap fault handler will acquire a recursive read-lock on memory_lock. Avoid this by reducing the lock granularity. Sequential accesses requiring multiple ioread/iowrite cycles are expected to be rare, therefore typical accesses should not see additional overhead. VGA MMIO accesses are expected to be non-fatal regardless of the PCI memory enable bit to allow legacy probing, this behavior remains with a comment added. ioeventfds are now included in memory access testing, with writes dropped while memory space is disabled.

2020-08-17watch_queue: Limit the number of watches a user can holdDavid Howells
Impose a limit on the number of watches that a user can hold so that they can't use this mechanism to fill up all the available memory. This is done by putting a counter in user_struct that's incremented when a watch is allocated and decreased when it is released. If the number exceeds the RLIMIT_NOFILE limit, the watch is rejected with EAGAIN. This can be tested by the following means: (1) Create a watch queue and attach it to fd 5 in the program given - in this case, bash: keyctl watch_session /tmp/nlog /tmp/gclog 5 bash (2) In the shell, set the maximum number of files to, say, 99: ulimit -n 99 (3) Add 200 keyrings: for ((i=0; i<200; i++)); do keyctl newring a$i @s || break; done (4) Try to watch all of the keyrings: for ((i=0; i<200; i++)); do echo $i; keyctl watch_add 5 %:a$i || break; done This should fail when the number of watches belonging to the user hits 99. (5) Remove all the keyrings and all of those watches should go away: for ((i=0; i<200; i++)); do keyctl unlink %:a$i; done (6) Kill off the watch queue by exiting the shell spawned by watch_session.

2020-08-17ASoC: codec: tlv3204: Moving GPIO reset and add ADC resetMichael Sit Wei Hong
Moving GPIO reset to a later stage and before clock registration to ensure that the host system and codec clocks are in sync. If the host register clock values prior to gpio reset, the last configured codec clock is registered to the host. The codec then gets gpio resetted setting the codec clocks to their default value, causing a mismatch. Host system will skip clock setting thinking the codec clocks are already at the requested rate. ADC reset is added to ensure the next audio capture does not have undesired artifacts. It is probably related to the original code where the probe function resets the ADC prior to 1st record.

While the widget is really just a simple switch, it is represented as a "mixer with named controls" to avoid including the widget name in the kcontrol name. Otherwise, it is not possible to give the widget an accurate, descriptive name without changing the kcontrol name seen by userspace (which should be stable).

The sun8i-codec driver provides ALSA controls for enabling/disabling each of the inputs to the AIF1 Slot 0 and DAC mixers. For two of these inputs (ADC->DAC and AIF1 DA0->AIF1 AD0), the audio source is implemented, so the mixer inputs can be used. However, because the DAPM routes are missing, these mixer inputs only work when both the source and the mixer happen to be part of other active audio paths. Adding the appropriate routes makes these ALSA controls function all of the time.

2020-08-17ASoC: sun8i-codec: Fix DAPM to match the hardware topologySamuel Holland
The A33/A64 digital codec has 4 physical inputs and 4 physical outputs: 3 AIFs/DAIs and one ADC/DAC pair. Internal routing is accomplished by a 4-channel mixer connected to each output. The analog and digital sides of the ADC/DAC are in separate ASoC components, so card-level DAPM routes (provided in the device tree) are necessary to connect them together. Currently, these routes are wrong. For AIF1 Playback, the correct topology is: ||<<============ sun8i-codec ===========>>|| || || CPU DAI -> AIF1 DA0 -> DAC Mixer -> DAC (digital) -> DAC (analog) || || but the driver and device trees currently describe: || || CPU DAI -> AIF1 DA0 -------------------------------> DAC (analog) || \--> DAC Mixer -> ??? [dead end] || For AIF1 Capture, there is an additional problem, because the Mixer route is backward. The topology should be: || || ADC (analog) -> ADC (digital) -> AIF1 AD0 Mixer -> AIF1 AD0 -> CPU DAI || || but the driver and device trees currently describe: || || ADC (analog) -> AIF1 AD0 ------------------------------------> CPU DAI || \--> ADC Mixer -> ??? [dead end] || The ADC/DAC are only powered because AIF1 AD0 (capture) has supply routes from the ADC, and AIF1 DA0 (playback) has supply routes from the DAC. However, neither set of supply routes matches the hardware topology. Audio can be routed among AIF1/2/3 without using the ADC or DAC at all; and audio can be routed from the ADC to the DAC without using any AIFs (via the "ADC Digital DAC Playback Switch"). Because the DAPM routes are wrong, both of these use cases are currently broken. This commit adds the necessary widgets and routes to represent the real hardware topology, with functionality equivalent to the current driver. For the existing "allwinner,sun8i-a33-codec" compatible, widgets with the old names are kept as wrappers around the new widgets, so existing device trees will continue to work. For "allwinner,sun50i-a64-codec", the old widgets can be omitted, because no device trees yet use that compatible.

The audio codecs in the A33 and A64 are both integrated variants of the X-Powers AC100 codec. However, there are some differences between them that merit having a separate compatible: - The A64 has a second DRC block, not present in the AC100 or A33. - The A33 has some extra muxing options for AIF1/2/3 in the AIF3_SGP_CTRL register, which are not present in the AC100 or A64. - The A33 is missing registers providing jack detection functionality. - The A33 is claimed to invert LRCK, but this is not seen on A64. Since the driver will continue to work on the A64 using the A33 compatible, albeit without jack detection functionality and with possibly inverted channels, as it does now, allow the A33 compatible to be used as a fallback.

2020-08-17ASoC: rt5682: Use clk_hw based APIs for registrationStephen Boyd
The (new?) style of clk registration uses clk_hw based APIs so that we can more easily see the difference between clk providers and clk consumers. Use the clk_hw based APIs to do this and migrate to devm for the clkdev creation so that we can reduce the amount of code.

I see a spew of "sysclk/dai not set correctly" whenever I cat /sys/kernel/debug/clk/clk_summary on my device. This is because the master pointer isn't set yet in this driver. A user isn't going to be able to do much if this check is failing so this error message isn't really an error, it's more of a kernel debug message. Lower the priority to dev_dbg() so that it isn't so noisy.

2020-08-17ASoC: wm8994: Avoid attempts to read unreadable registersSylwester Nawrocki
The driver supports WM1811, WM8994, WM8958 devices but according to documentation and the regmap definitions the WM8958_DSP2_* registers are only available on WM8958. In current code these registers are being accessed as if they were available on all the three chips. When starting playback on WM1811 CODEC multiple errors like: "wm8994-codec wm8994-codec: ASoC: error at soc_component_read_no_lock on wm8994-codec: -5" can be seen, which is caused by attempts to read an unavailable WM8958_DSP2_PROGRAM register. The issue has been uncovered by recent commit "e2329ee ASoC: soc-component: add soc_component_err()". This patch adds a check in wm8958_aif_ev() callback so the DSP2 handling is only done for WM8958.
