2020-12-17Merge tag 'iommu-updates-v5.11' of ↵Linus Torvalds3-7/+37
git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux Pull IOMMU updates from Will Deacon: "There's a good mixture of improvements to the core code and driver changes across the board. One thing worth pointing out is that this includes a quirk to work around behaviour in the i915 driver (see 65f746e8285f ("iommu: Add quirk for Intel graphic devices in map_sg")), which otherwise interacts badly with the conversion of the intel IOMMU driver over to the DMA-IOMMU APU but has being fixed properly in the DRM tree. We'll revert the quirk later this cycle once we've confirmed that things don't fall apart without it. Summary: - IOVA allocation optimisations and removal of unused code - Introduction of DOMAIN_ATTR_IO_PGTABLE_CFG for parameterising the page-table of an IOMMU domain - Support for changing the default domain type in sysfs - Optimisation to the way in which identity-mapped regions are created - Driver updates: * Arm SMMU updates, including continued work on Shared Virtual Memory * Tegra SMMU updates, including support for PCI devices * Intel VT-D updates, including conversion to the IOMMU-DMA API - Cleanup, kerneldoc and minor refactoring" * tag 'iommu-updates-v5.11' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: (50 commits) iommu/amd: Add sanity check for interrupt remapping table length macros dma-iommu: remove __iommu_dma_mmap iommu/io-pgtable: Remove tlb_flush_leaf iommu: Stop exporting free_iova_mem() iommu: Stop exporting alloc_iova_mem() iommu: Delete split_and_remove_iova() iommu/io-pgtable-arm: Remove unused 'level' parameter from iopte_type() macro iommu: Defer the early return in arm_(v7s/lpae)_map iommu: Improve the performance for direct_mapping iommu: avoid taking iova_rbtree_lock twice iommu/vt-d: Avoid GFP_ATOMIC where it is not needed iommu/vt-d: Remove set but not used variable iommu: return error code when it can't get group iommu: Fix htmldocs warnings in sysfs-kernel-iommu_groups iommu: arm-smmu-impl: Add a space before open parenthesis iommu: arm-smmu-impl: Use table to list QCOM implementations iommu/arm-smmu: Move non-strict mode to use io_pgtable_domain_attr iommu/arm-smmu: Add support for pagetable config domain attribute iommu: Document usage of "/sys/kernel/iommu_groups/<grp_id>/type" file iommu: Take lock before reading iommu group default domain type ...

2020-12-16reboot: allow to specify reboot mode via sysfsMatteo Croce1-0/+32
The kernel cmdline reboot= option offers some sort of control on how the reboot is issued. We don't always know in advance what type of reboot to perform. Sometimes a warm reboot is preferred to persist certain memory regions across the reboot. Others a cold one is needed to apply a future system update that makes a memory memory model change, like changing the base page size or resizing a persistent memory region. Or simply we want to enable reboot_force because we noticed that something bad happened. Add handles in sysfs to allow setting these reboot options, so they can be changed when the system is booted, other than at boot time. The handlers are under <sysfs>/kernel/reboot, can be read to get the current configuration and written to alter it. # cd /sys/kernel/reboot/ # grep . * cpu:0 force:0 mode:cold type:acpi # echo 2 >cpu # echo yes >force # echo soft >mode # echo bios >type # grep . * cpu:2 force:1 mode:soft type:bios Before setting anything, check for CAP_SYS_BOOT capability, so it's possible to allow an unpriviledged process to change these settings simply by relaxing the handles permissions, without opening them to the world.

2020-12-16proc: provide details on indirect branch speculationAnand K Mistry1-0/+2
Similar to speculation store bypass, show information about the indirect branch speculation mode of a task in /proc/$pid/status. For testing/benchmarking, I needed to see whether IB (Indirect Branch) speculation (see Spectre-v2) is enabled on a task, to see whether an IBPB instruction should be executed on an address space switch. Unfortunately, this information isn't available anywhere else and currently the only way to get it is to hack the kernel to expose it (like this change). It also helped expose a bug with conditional IB speculation on certain CPUs. Another place this could be useful is to audit the system when using sanboxing. With this change, I can confirm that seccomp-enabled process have IB speculation force disabled as expected when the kernel command line parameter `spectre_v2_user=seccomp`. Since there's already a 'Speculation_Store_Bypass' field, I used that as precedent for adding this one.

Pull nfsd updates from Chuck Lever: "Several substantial changes this time around: - Previously, exporting an NFS mount via NFSD was considered to be an unsupported feature. With v5.11, the community has attempted to make re-exporting a first-class feature of NFSD. This would enable the Linux in-kernel NFS server to be used as an intermediate cache for a remotely-located primary NFS server, for example, even with other NFS server implementations, like a NetApp filer, as the primary. - A short series of patches brings support for multiple RPC/RDMA data chunks per RPC transaction to the Linux NFS server's RPC/RDMA transport implementation. This is a part of the RPC/RDMA spec that the other premiere NFS/RDMA implementation (Solaris) has had for a very long time, and completes the implementation of RPC/RDMA version 1 in the Linux kernel's NFS server. - Long ago, NFSv4 support was introduced to NFSD using a series of C macros that hid dprintk's and goto's. Over time, the kernel's XDR implementation has been greatly improved, but these C macros have remained and become fallow. A series of patches in this pull request completely replaces those macros with the use of current kernel XDR infrastructure. Benefits include: - More robust input sanitization in NFSD's NFSv4 XDR decoders. - Make it easier to use common kernel library functions that use XDR stream APIs (for example, GSS-API). - Align the structure of the source code with the RFCs so it is easier to learn, verify, and maintain our XDR implementation. - Removal of more than a hundred hidden dprintk() call sites. - Removal of some explicit manipulation of pages to help make the eventual transition to xdr->bvec smoother. - On top of several related fixes in 5.10-rc, there are a few more fixes to get the Linux NFSD implementation of NFSv4.2 inter-server copy up to speed. And as usual, there is a pinch of seasoning in the form of a collection of unrelated minor bug fixes and clean-ups.

Summary: - Many cleanups around probe/remove and error handling from Lukas Wunner and Uwe Kleine-König, and further fixes around PM from Zhang Qilong. - Provide a mask for which bits of the mode can safely be configured by drivers and use that to fix an issue with the ADS7846 driver. - Documentation of the expected interactions between SPI and GPIO level chip select polarity configuration from H.

Since we changed the pgdat->lru_lock to lruvec->lru_lock, it's time to fix the incorrect comments in code. Also fixed some zone->lru_lock comment error from ancient time. etc. I struggled to understand the comment above move_pages_to_lru() (surely it never calls page_referenced()), and eventually realized that most of it had got separated from shrink_active_list(): move that comment back.

2020-12-15zram: add stat to gather incompressible pages since zram set upMinchan Kim1-0/+1
Currently, zram supports the stat via /sys/block/zram/mm_stat to represent how many of incompressible pages are stored at the moment but it couldn't show how many times incompressible pages were wrote down since zram set up. It's also good indication to see how zram is effective in the system.

2020-12-15zram: support page writebackMinchan Kim1-0/+5
There is demand to writeback specific process pages to backing store instead of all idles pages in the system due to storage wear out concerns and to launching latency of apps which are most of the time idle but are critical for resume latency. This patch extends the writeback knob to support a specific page writeback.

2020-12-15userfaultfd: add user-mode only option to unprivileged_userfaultfd sysctl knobLokesh Gidra1-5/+10
With this change, when the knob is set to 0, it allows unprivileged users to call userfaultfd, like when it is set to 1, but with the restriction that page faults from only user-mode can be handled. In this mode, an unprivileged user (without SYS_CAP_PTRACE capability) must pass UFFD_USER_MODE_ONLY to userfaultd or the API will fail with EPERM. This enables administrators to reduce the likelihood that an attacker with access to userfaultfd can delay faulting kernel code to widen timing windows for other exploits. The default value of this knob is changed to 0. This is required for correct functioning of pipe mutex. However, this will fail postcopy live migration, which will be unnoticeable to the VM guests. To avoid this, set 'vm.userfault = 1' in /sys/sysctl.conf. The main reason this change is desirable as in the short term is that the Android userland will behave as with the sysctl set to zero. So without this commit, any Linux binary using userfaultfd to manage its memory would behave differently if run within the Android userland. For more details, refer to Andrea's reply [1].

2020-12-15arm: remove CONFIG_ARCH_HAS_HOLES_MEMORYMODELMike Rapoport1-2/+1
ARM is the only architecture that defines CONFIG_ARCH_HAS_HOLES_MEMORYMODEL which in turn enables memmap_valid_within() function that is intended to verify existence of struct page associated with a pfn when there are holes in the memory map. However, the ARCH_HAS_HOLES_MEMORYMODEL also enables HAVE_ARCH_PFN_VALID and arch-specific pfn_valid() implementation that also deals with the holes in the memory map. The only two users of memmap_valid_within() call this function after a call to pfn_valid() so the memmap_valid_within() check becomes redundant. Remove CONFIG_ARCH_HAS_HOLES_MEMORYMODEL and memmap_valid_within() and rely entirely on ARM's implementation of pfn_valid() that is now enabled unconditionally.

For many workloads, pagetable consumption is significant and it makes sense to expose it in the memory.stat for the memory cgroups. However at the moment, the pagetables are accounted per-zone. Converting them to per-node and using the right interface will correctly account for the memory cgroups as well.

As huge page usage in the page cache and for shmem files proliferates in our production environment, the performance monitoring team has asked for per-cgroup stats on those pages. We already track and export anon_thp per cgroup. We already track file THP and shmem THP per node, so making them per-cgroup is only a matter of switching from node to lruvec counters. All callsites are in places where the pages are charged and locked, so page->memcg is stable.

2020-12-15selftests/vm: only some gup_test items are really benchmarksJohn Hubbard1-1/+1
Therefore, some minor cleanup and improvements are in order: 1. Rename the other items appropriately. 2. Stop reporting timing information on the non-benchmark items. It's still being recorded and is available, but there's no point in cluttering up the report with data that no one reasonably needs to check. 3. Don't do iterations, for non-benchmark items. 4. Print out a shorter, more appropriate report for the non-benchmark tests. 5. Add the command that was run, to the report. This really helps, as there are quite a lot of options now. 6. Use a larger integer type for cmd, now that it's being compared Otherwise it doesn't work, because in this case cmd is about 3 billion, which is the perfect size for problems with signed vs unsigned int.
