2022-09-28hyperv: simplify and rename generate_guest_idLi kunyu
The generate_guest_id function is more suitable for use after the following modifications. 1. The return value of the function is modified to u64. 2. Remove the d_info1 and d_info2 parameters from the function, keep the u64 type kernel_version parameter. 3. Rename the function to make it clearly a Hyper-V related function, and modify it to hv_generate_guest_id.

2022-09-28irqchip: Make irqchip_init() usable on pure ACPI systemsHuacai Chen
Pure ACPI systems (e.g., LoongArch) do not need OF_IRQ, but still require irqchip_init() to perform the ACPI irqchip probing, even when OF_IRQ isn't selected. Relax the dependency to enable the generic irqchip support when ACPI_GENERIC_GSI is configured.

2022-09-28ata: libata-sata: Fix device queue depth controlDamien Le Moal
The function __ata_change_queue_depth() uses the helper ata_scsi_find_dev() to get the ata_device structure of a scsi device and set that device maximum queue depth. However, when the ata device is managed by libsas, ata_scsi_find_dev() returns NULL, turning __ata_change_queue_depth() into a nop, which prevents the user from setting the maximum queue depth of ATA devices used with libsas based HBAs. Fix this by renaming __ata_change_queue_depth() to ata_change_queue_depth() and adding a pointer to the ata_device structure of the target device as argument. This pointer is provided by ata_scsi_change_queue_depth() using ata_scsi_find_dev() in the case of a libata managed device and by sas_change_queue_depth() using sas_to_ata_dev() in the case of a libsas managed ata device.

2022-09-28powerpc/rtas: block error injection when locked downNathan Lynch
The error injection facility on pseries VMs allows corruption of arbitrary guest memory, potentially enabling a sufficiently privileged user to disable lockdown or perform other modifications of the running kernel via the rtas syscall.

2022-09-28powerpc/pseries: block untrusted device tree changes when locked downNathan Lynch
The /proc/powerpc/ofdt interface allows the root user to freely alter the in-kernel device tree, enabling arbitrary physical address writes via drivers that could bind to malicious device nodes, thus making it possible to disable lockdown. Historically this interface has been used on the pseries platform to facilitate the runtime addition and removal of processor, memory, and device resources (aka Dynamic Logical Partitioning or DLPAR). Years ago, the processor and memory use cases were migrated to designs that happen to be lockdown-friendly: device tree updates are communicated directly to the kernel from firmware without passing through untrusted user space. I/O device DLPAR via the "drmgr" command in powerpc-utils remains the sole legitimate user of /proc/powerpc/ofdt, but it is already broken in lockdown since it uses /dev/mem to allocate argument buffers for the rtas syscall. So only illegitimate uses of the interface should see a behavior change when running on a locked down kernel.

2022-09-28sched: Fix TASK_state comparisonsPeter Zijlstra
Task state is fundamentally a bitmask; direct comparisons are probably not working as intended. Specifically the normal wait-state have a number of possible modifiers: TASK_UNINTERRUPTIBLE: TASK_WAKEKILL, TASK_NOLOAD, TASK_FREEZABLE TASK_INTERRUPTIBLE: TASK_FREEZABLE Specifically, the addition of TASK_FREEZABLE wrecked __wait_is_interruptible(). This however led to an audit of direct comparisons yielding the rest of the changes.

2022-09-28kallsyms: increase maximum kernel symbol length to 512Miguel Ojeda
Rust symbols can become quite long due to namespacing introduced by modules, types, traits, generics, etc. For instance, the following code: pub mod my_module { pub struct MyType; pub struct MyGenericType<T>(T); pub trait MyTrait { fn my_method() -> u32; } impl MyTrait for MyGenericType<MyType> { fn my_method() -> u32 { 42 } } } generates a symbol of length 96 when using the upcoming v0 mangling scheme: _RNvXNtCshGpAVYOtgW1_7example9my_moduleINtB2_13MyGenericTypeNtB2_6MyTypeENtB2_7MyTrait9my_method At the moment, Rust symbols may reach up to 300 in length. Setting 512 as the maximum seems like a reasonable choice to keep some headroom.

2022-09-27RDMA/mlx5: Don't set tx affinity when lag is in hash modeLiu, Changcheng
In hash mode, without setting tx affinity explicitly, the port select flow table decides which port is used for the traffic. If port_select_flow_table_bypass capability is supported and tx affinity is set explicitly for QP/TIS, they will be added into the explicit affinity table in FW to check which port is used for the traffic. 1. The overloaded explicit affinity table may affect performance. To avoid this, do not set tx affinity explicitly by default. 2. The packets of the same flow need to be transmitted on the same port. Because the packets of the same flow use different QPs in slow & fast path, it shouldn't set tx affinity explicitly for these QPs.

In include/uapi/rdma/rdma_user_rxe.h there are redundant copies of num_sge in the rxe_send_wr, rxe_recv_wqe, and rxe_dma_info. Only the ones in rxe_dma_info are actually used by the rxe kernel driver. The userspace would set these values, but the kernel never read them. This change has no affect on the current ABI and new or old versions of rdma-core operate correctly with new or old versions of the kernel rxe driver.

2022-09-27RDMA/mlx5: Add support for dmabuf to devx umemJason Gunthorpe
This is modeled after the similar EFA enablement in commit 66f4817b5712 ("RDMA/efa: Add support for dmabuf memory regions"). Like EFA there is no support for revocation so we simply call the ib_umem_dmabuf_get_pinned() to obtain a umem instead of the normal ib_umem_get(). Everything else stays the same.

2022-09-27RDMA/core: Add UVERBS_ATTR_RAW_FDJason Gunthorpe
This uses the same passing protocol as UVERBS_ATTR_FD (eg len = 0 data_s64 = fd), except that the FD is not required to be a uverbs object and the core code does not covert the FD to an object handle automatically. Access to the int fd is provided by uverbs_get_raw_fd(). Link: https://lore.kernel.org/r/2-v1-bd147097458e+ede-umem_dmabuf_jgg@nvidia.com Signed-off-by: Jason Gunthorpe <jgg@nvidia.com>

2022-09-27efi: zboot: create MemoryMapped() device path for the parent if neededArd Biesheuvel
LoadImage() is supposed to install an instance of the protocol EFI_LOADED_IMAGE_DEVICE_PATH_PROTOCOL onto the loaded image's handle so that the program can figure out where it was loaded from. The reference implementation even does this (with a NULL protocol pointer) if the call to LoadImage() used the source buffer and size arguments, and passed NULL for the image device path. Hand rolled implementations of LoadImage may behave differently, though, and so it is better to tolerate situations where the protocol is missing. And actually, concatenating an Offset() node to a NULL device path (as we do currently) is not great either. So in cases where the protocol is absent, or when it points to NULL, construct a MemoryMapped() device node as the base node that describes the parent image's footprint in memory.

2022-09-27Merge tag 'efi-loongarch-for-v6.1-2' into HEADArd Biesheuvel
Second shared stable tag between EFI and LoongArch trees This is necessary because the EFI libstub refactoring patches are mostly directed at enabling LoongArch to wire up generic EFI boot support without being forced to consume DT properties that conflict with information that EFI also provides, e.g., memory map and reservations, etc.
2022-09-27efi: libstub: install boot-time memory map as config tableArd Biesheuvel
Expose the EFI boot time memory map to the kernel via a configuration table. This is arch agnostic and enables future changes that remove the dependency on DT on architectures that don't otherwise rely on it. Signed-off-by: Ard Biesheuvel <ardb@kernel.org>
2022-09-27efi: libstub: unify initrd loading between architecturesArd Biesheuvel
Use a EFI configuration table to pass the initrd to the core kernel, instead of per-arch methods. This cleans up the code considerably, and should make it easier for architectures to get rid of their reliance on DT for doing EFI boot in the future. Signed-off-by: Ard Biesheuvel <ardb@kernel.org>
2022-09-27ASoC: SOF: control.h: Replace zero-length array with DECLARE_FLEX_ARRAY() helperGustavo A. R. Silva
Zero-length arrays are deprecated and we are moving towards adopting C99 flexible-array members, instead. So, replace zero-length arrays declarations in anonymous union with the new DECLARE_FLEX_ARRAY() helper macro. This helper allows for flexible-array members in unions.

2022-09-27ALSA: pcm: Avoid reference to status->stateTakashi Iwai
In the PCM core and driver code, there are lots place referring to the current PCM state via runtime->status->state. This patch introduced a local PCM state in runtime itself and replaces those references with runtime->state. It has improvements in two aspects: - The reduction of a indirect access leads to more code optimization - It avoids a possible (unexpected) modification of the state via mmap of the status record The status->state is updated together with runtime->state, so that user-space can still read the current state via mmap like before, too. This patch touches only the ALSA core code. The changes in each driver will follow in later patches.
