2022-05-13iommu/dma: Explicitly sort PCI DMA windowsRobin Murphy
Originally, creating the dma_ranges resource list in pre-sorted fashion was the simplest and most efficient way to enforce the order required by iova_reserve_pci_windows(). However since then at least one PCI host driver is now re-sorting the list for its own probe-time processing, which doesn't seem entirely unreasonable, so that basic assumption no longer holds. Make iommu-dma robust and get the sort order it needs by explicitly sorting, which means we can also save the effort at creation time and just build the list in whatever natural order the DT had.

2022-05-13iommu/dma: Fix iova map result check bugYunfei Wang
The data type of the return value of the iommu_map_sg_atomic is ssize_t, but the data type of iova size is size_t, e.g. one is int while the other is unsigned int. When iommu_map_sg_atomic return value is compared with iova size, it will force the signed int to be converted to unsigned int, if iova map fails and iommu_map_sg_atomic return error code is less than 0, then (ret < iova_len) is false, which will to cause not do free iova, and the master can still successfully get the iova of map fail, which is not expected. Therefore, we need to check the return value of iommu_map_sg_atomic in two cases according to whether it is less than 0.

2022-05-13iommu/mediatek: Fix NULL pointer dereference when printing dev_nameMiles Chen
When larbdev is NULL (in the case I hit, the node is incorrectly set iommus = <&iommu NUM>), it will cause device_link_add() fail and kernel crashes when we try to print dev_name(larbdev). Let's fail the probe if a larbdev is NULL to avoid invalid inputs from dts. It should work for normal correct setting and avoid the crash caused by my incorrect setting.

2022-05-13iommu: iommu_group_claim_dma_owner() must always assign a domainJason Gunthorpe via iommu
Once the group enters 'owned' mode it can never be assigned back to the default_domain or to a NULL domain. It must always be actively assigned to a current domain. If the caller hasn't provided a domain then the core must provide an explicit DMA blocking domain that has no DMA map. Lazily create a group-global blocking DMA domain when iommu_group_claim_dma_owner is first called and immediately assign the group to it. This ensures that DMA is immediately fully isolated on all IOMMU drivers. If the user attaches/detaches while owned then detach will set the group back to the blocking domain. Slightly reorganize the call chains so that __iommu_group_set_core_domain() is the function that removes any caller configured domain and sets the domains back a core owned domain with an appropriate lifetime. __iommu_group_set_domain() is the worker function that can change the domain assigned to a group to any target domain, including NULL. Add comments clarifying how the NULL vs detach_dev vs default_domain works based on Robin's remarks. This fixes an oops with VFIO and SMMUv3 because VFIO will call iommu_detach_group() and then immediately iommu_domain_free(), but SMMUv3 has no way to know that the domain it is holding a pointer to has been freed. Now the iommu_detach_group() will assign the blocking domain and SMMUv3 will no longer hold a stale domain reference.

Instead of always returning -ENOPKG, decode the firmware error code further when the HWRM_NVM_INSTALL_UPDATE firmware call fails.

This is version 2 of the earlier patch that was reverted: 02acd399533e ("bnxt_en: parse result field when NVRAM package install fails") In this new version, if the call is made through devlink instead of ethtool, we'll also set the error message in extack.

2022-05-13platform/chrome: Add ChromeOS ACPI device driverEnric Balletbo i Serra
The x86 Chromebooks have the ChromeOS ACPI device. This driver attaches to the ChromeOS ACPI device and exports the values reported by ACPI in a sysfs directory. This data isn't present in ACPI tables when read through ACPI tools, hence a driver is needed to do it. The driver gets data from firmware using the ACPI component of the kernel. The ACPI values are presented in string form (numbers as decimal values) or binary blobs, and can be accessed as the contents of the appropriate read only files in the standard ACPI device's sysfs directory tree. This data is consumed by the ChromeOS user space.

2022-05-13dma-buf: ensure unique directory name for dmabuf statsCharan Teja Kalla
The dmabuf file uses get_next_ino()(through dma_buf_getfile() -> alloc_anon_inode()) to get an inode number and uses the same as a directory name under /sys/kernel/dmabuf/buffers/<ino>. This directory is used to collect the dmabuf stats and it is created through dma_buf_stats_setup(). At current, failure to create this directory entry can make the dma_buf_export() to fail. Now, as the get_next_ino() can definitely give a repetitive inode no causing the directory entry creation to fail with -EEXIST. This is a problem on the systems where dmabuf stats functionality is enabled on the production builds can make the dma_buf_export(), though the dmabuf memory is allocated successfully, to fail just because it couldn't create stats entry. This issue we are able to see on the snapdragon system within 13 days where there already exists a directory with inode no "122602" so dma_buf_stats_setup() failed with -EEXIST as it is trying to create the same directory entry. To make the dentry name as unique, use the dmabuf fs specific inode which is based on the simple atomic variable increment. There is tmpfs subsystem too which relies on its own inode generation rather than relying on the get_next_ino() for the same reason of avoiding the duplicate inodes[1].

2022-05-13net: axienet: Use NAPI for TX completion pathRobert Hancock
This driver was using the TX IRQ handler to perform all TX completion tasks. Under heavy TX network load, this can cause significant irqs-off latencies (found to be in the hundreds of microseconds using ftrace). This can cause other issues, such as overrunning serial UART FIFOs when using high baud rates with limited UART FIFO sizes. Switch to using a NAPI poll handler to perform the TX completion work to get this out of hard IRQ context and avoid the IRQ latency impact. A separate poll handler is used for TX and RX since they have separate IRQs on this controller, so that the completion work for each of them stays on the same CPU as the interrupt. Testing on a Xilinx MPSoC ZU9EG platform using iperf3 from a Linux PC through a switch at 1G link speed showed no significant change in TX or RX throughput, with approximately 941 Mbps before and after. Hard IRQ time in the TX throughput test was significantly reduced from 12% to below 1% on the CPU handling TX interrupts, with total hard+soft IRQ CPU usage dropping from about 56% down to 48%.

2022-05-13net: axienet: Be more careful about updating tx_bd_tailRobert Hancock
The axienet_start_xmit function was updating the tx_bd_tail variable multiple times, with potential rollbacks on error or invalid intermediate positions, even though this variable is also used in the TX completion path. Use READ_ONCE where this variable is read and WRITE_ONCE where it is written to make this update more atomic, and move the write before the MMIO write to start the transfer, so it is protected by that implicit write barrier.

2022-05-13Bluetooth: hci_qca: Use del_timer_sync() before freeingSteven Rostedt
While looking at a crash report on a timer list being corrupted, which usually happens when a timer is freed while still active. This is commonly triggered by code calling del_timer() instead of del_timer_sync() just before freeing. One possible culprit is the hci_qca driver, which does exactly that. Eric mentioned that wake_retrans_timer could be rearmed via the work queue, so also move the destruction of the work queue before del_timer_sync().

2022-05-13Bluetooth: btintel: Constify static struct regmap_busRikard Falkeborn
The only usage of regmap_ibt is to (after the regmap_init() macro is expanded), pass its address to __regmap_init(), which takes a pointer to const struct regmap_bus as input. Make it const to allow the compiler to put it in read-only memory. Signed-off-by: Rikard Falkeborn <rikard.falkeborn@gmail.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
