2024-11-07md/raid5: Wait sync io to finish before changing group cntXiao Ni
One customer reports a bug: raid5 is hung when changing thread cnt while resync is running. The stripes are all in conf->handle_list and new threads can't handle them. Commit b39f35ebe86d ("md: don't quiesce in mddev_suspend()") removes pers->quiesce from mddev_suspend/resume. Before this patch, mddev_suspend needs to wait for all ios including sync io to finish. Now it's used to only wait normal io. Fix this by calling raid5_quiesce from raid5_store_group_thread_cnt directly to wait all sync requests to finish before changing the group cnt.

2024-11-07vdpa/mlx5: Fix error path during device addDragos Tatulea
In the error recovery path of mlx5_vdpa_dev_add(), the cleanup is executed and at the end put_device() is called which ends up calling mlx5_vdpa_free(). This function will execute the same cleanup all over again. Most resources support being cleaned up twice, but the recent mlx5_vdpa_destroy_mr_resources() doesn't. This change drops the explicit cleanup from within the mlx5_vdpa_dev_add() and lets mlx5_vdpa_free() do its work. This issue was discovered while trying to add 2 vdpa devices with the same name: $> vdpa dev add name vdpa-0 mgmtdev auxiliary/mlx5_core.sf.2 $> vdpa dev add name vdpa-0 mgmtdev auxiliary/mlx5_core.sf.3 ... yields the following dump: BUG: kernel NULL pointer dereference, address: 00000000000000b8 #PF: supervisor read access in kernel mode #PF: error_code(0x0000) - not-present page PGD 0 P4D 0 Oops: Oops: 0000 [#1] SMP CPU: 4 UID: 0 PID: 2811 Comm: vdpa Not tainted 6.12.0-rc6 #1 Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS rel-1.13.0-0-gf21b5a4aeb02-prebuilt.qemu.org 04/01/2014 RIP: 0010:destroy_workqueue+0xe/0x2a0 Code: ...

iommufd_fault_iopf_enable has limitation to PRI on PCI/SRIOV VFs because the PRI might be a shared resource and current iommu subsystem is not ready to support enabling/disabling PRI on a VF without any impact on others. However, we have devices that appear as PCI but are actually on the AMBA bus. These fake PCI devices have PASID capability, support stall as well as SRIOV, so remove the limitation for these devices.

2024-11-07drm/panthor: Be stricter about IO mapping flagsJann Horn
The current panthor_device_mmap_io() implementation has two issues: 1. For mapping DRM_PANTHOR_USER_FLUSH_ID_MMIO_OFFSET, panthor_device_mmap_io() bails if VM_WRITE is set, but does not clear VM_MAYWRITE. That means userspace can use mprotect() to make the mapping writable later on. This is a classic Linux driver gotcha. I don't think this actually has any impact in practice: When the GPU is powered, writes to the FLUSH_ID seem to be ignored; and when the GPU is not powered, the dummy_latest_flush page provided by the driver is deliberately designed to not do any flushes, so the only thing writing to the dummy_latest_flush could achieve would be to make *more* flushes happen. 2. panthor_device_mmap_io() does not block MAP_PRIVATE mappings (which are mappings without the VM_SHARED flag). MAP_PRIVATE in combination with VM_MAYWRITE indicates that the VMA has copy-on-write semantics, which for VM_PFNMAP are semi-supported but fairly cursed. In particular, in such a mapping, the driver can only install PTEs during mmap() by calling remap_pfn_range() (because remap_pfn_range() wants to **store the physical address of the mapped physical memory into the vm_pgoff of the VMA**); installing PTEs later on with a fault handler (as panthor does) is not supported in private mappings, and so if you try to fault in such a mapping, vmf_insert_pfn_prot() splats when it hits a BUG() check. Fix it by clearing the VM_MAYWRITE flag (userspace writing to the FLUSH_ID doesn't make sense) and requiring VM_SHARED (copy-on-write semantics for the FLUSH_ID don't make sense). Reproducers for both scenarios are in the notes of my patch on the mailing list; I tested that these bugs exist on a Rock 5B machine. Note that I only compile-tested the patch, I haven't tested it; I don't have a working kernel build setup for the test machine yet. Please test it before applying it.

RSS configuration should be updated with queue number. In particular, it should be updated when (1) rss enabled and (2) default rss configuration is used without user modification. During rss command processing, device updates queue_pairs using rss.max_tx_vq. That is, the device updates queue_pairs together with rss, so we can skip the sperate queue_pairs update (VIRTIO_NET_CTRL_MQ_VQ_PAIRS_SET below) and return directly. Also remove the `vi->has_rss ?` check when setting vi->rss.max_tx_vq, because this is not used in the other hash_report case. Fixes: c7114b1249fa ("drivers/net/virtio_net: Added basic RSS support.")

However, the actual size of indirection_table was set as VIRTIO_NET_RSS_MAX_TABLE_LEN=128. This collision may cause issues if the vi->rss_indir_table_size exceeds 128. This patch instead uses dynamic indirection table, allocated with vi->rss after vi->rss_indir_table_size initialized. And free it in virtnet_remove(). In virtnet_commit_rss_command(), sgs for rss is initialized differently with hash_report. So indirection_table is not used if !vi->has_rss, and then we don't need to alloc indirection_table for hash_report only uses. Fixes: c7114b1249fa ("drivers/net/virtio_net: Added basic RSS support.")

2024-11-07arm64: smccc: Remove broken support for SMCCCv1.3 SVE discard hintMark Rutland
SMCCCv1.3 added a hint bit which callers can set in an SMCCC function ID (AKA "FID") to indicate that it is acceptable for the SMCCC implementation to discard SVE and/or SME state over a specific SMCCC call. The kernel support for using this hint is broken and SMCCC calls may clobber the SVE and/or SME state of arbitrary tasks, though FPSIMD state is unaffected. The kernel support is intended to use the hint when there is no SVE or SME state to save, and to do this it checks whether TIF_FOREIGN_FPSTATE is set or TIF_SVE is clear in assembly code: | ldr <flags>, [<current_task>, #TSK_TI_FLAGS] | tbnz <flags>, #TIF_FOREIGN_FPSTATE, 1f // Any live FP state? | tbnz <flags>, #TIF_SVE, 2f // Does that state include SVE? | | 1: orr <fid>, <fid>, ARM_SMCCC_1_3_SVE_HINT | 2: | << SMCCC call using FID >> This is not safe as-is: (1) SMCCC calls can be made in a preemptible context and preemption can result in TIF_FOREIGN_FPSTATE being set or cleared at arbitrary points in time. Thus checking for TIF_FOREIGN_FPSTATE provides no guarantee. (2) TIF_FOREIGN_FPSTATE only indicates that the live FP/SVE/SME state in the CPU does not belong to the current task, and does not indicate that clobbering this state is acceptable. When the live CPU state is clobbered it is necessary to update fpsimd_last_state.st to ensure that a subsequent context switch will reload FP/SVE/SME state from memory rather than consuming the clobbered state. This and the SMCCC call itself must happen in a critical section with preemption disabled to avoid races. (3) Live SVE/SME state can exist with TIF_SVE clear (e.g. with only TIF_SME set), and checking TIF_SVE alone is insufficient. Remove the broken support for the SMCCCv1.3 SVE saving hint. This is effectively a revert of commits: * cfa7ff959a78 ("arm64: smccc: Support SMCCC v1.3 SVE register saving hint") * a7c3acca5380 ("arm64: smccc: Save lr before calling __arm_smccc_sve_check()") ... leaving behind the ARM_SMCCC_VERSION_1_3 and ARM_SMCCC_1_3_SVE_HINT definitions, since these are simply definitions from the SMCCC specification, and the latter is used in KVM via ARM_SMCCC_CALL_HINTS. If we want to bring this back in future, we'll probably want to handle this logic in C where we can use all the usual FPSIMD/SVE/SME helper functions, and that'll likely require some rework of the SMCCC code and/or its callers.
