Please apply 3f1e53abff84c (" netfilter: ebtables: don't attempt to allocate 0-sized compat array") to v4.14.y and later

by Guenter Roeck

Hi Greg, Commit 3f1e53abff84c fixes commit 7d7d7e02111e9 ("("netfilter: compat: reject huge allocation requests"), which has found its way into 4.14.y and 4.16.y. This causes syzcaller hiccups at least in 4.14.y (more specifically chromeos-4.14). Please apply 3f1e53abff84c to v4.14.y and v4.16.y to fix the problem. Copying Dave and netdev in case he wants to handle it. Sorry for the noise if this has already been queued. Thanks, Guenter

[PATCH v9 0/9] dax: fix dma vs truncate/hole-punch

by Dan Williams

Changes since v8 [1]: * Rebase on v4.17-rc2 * Fix get_user_pages_fast() for ZONE_DEVICE pages to revalidate the pte, pmd, pud after taking references (Jan) * Kill dax_layout_lock(). With get_user_pages_fast() for ZONE_DEVICE fixed we can then rely on the {pte,pmd}_lock to synchronize dax_layout_busy_page() vs new page references (Jan) * Hold the iolock over repeated invocations of dax_layout_busy_page() to enable truncate/hole-punch to make forward progress in the presence of a constant stream of new direct-I/O requests (Jan). [1]: https://lists.01.org/pipermail/linux-nvdimm/2018-March/015058.html --- Background: get_user_pages() in the filesystem pins file backed memory pages for access by devices performing dma. However, it only pins the memory pages not the page-to-file offset association. If a file is truncated the pages are mapped out of the file and dma may continue indefinitely into a page that is owned by a device driver. This breaks coherency of the file vs dma, but the assumption is that if userspace wants the file-space truncated it does not matter what data is inbound from the device, it is not relevant anymore. The only expectation is that dma can safely continue while the filesystem reallocates the block(s). Problem: This expectation that dma can safely continue while the filesystem changes the block map is broken by dax. With dax the target dma page *is* the filesystem block. The model of leaving the page pinned for dma, but truncating the file block out of the file, means that the filesytem is free to reallocate a block under active dma to another file and now the expected data-incoherency situation has turned into active data-corruption. Solution: Defer all filesystem operations (fallocate(), truncate()) on a dax mode file while any page/block in the file is under active dma. This solution assumes that dma is transient. Cases where dma operations are known to not be transient, like RDMA, have been explicitly disabled via commits like 5f1d43de5416 "IB/core: disable memory registration of filesystem-dax vmas". The dax_layout_busy_page() routine is called by filesystems with a lock held against mm faults (i_mmap_lock) to find pinned / busy dax pages. The process of looking up a busy page invalidates all mappings to trigger any subsequent get_user_pages() to block on i_mmap_lock. The filesystem continues to call dax_layout_busy_page() until it finally returns no more active pages. This approach assumes that the page pinning is transient, if that assumption is violated the system would have likely hung from the uncompleted I/O. --- Dan Williams (9): dax, dm: introduce ->fs_{claim,release}() dax_device infrastructure mm, dax: enable filesystems to trigger dev_pagemap ->page_free callbacks memremap: split devm_memremap_pages() and memremap() infrastructure mm, dev_pagemap: introduce CONFIG_DEV_PAGEMAP_OPS mm: fix __gup_device_huge vs unmap mm, fs, dax: handle layout changes to pinned dax mappings xfs: prepare xfs_break_layouts() to be called with XFS_MMAPLOCK_EXCL xfs: prepare xfs_break_layouts() for another layout type xfs, dax: introduce xfs_break_dax_layouts() drivers/dax/super.c | 99 ++++++++++++++++++++-- drivers/md/dm.c | 57 +++++++++++++ drivers/nvdimm/pmem.c | 3 - fs/Kconfig | 2 fs/dax.c | 97 +++++++++++++++++++++ fs/ext2/super.c | 6 + fs/ext4/super.c | 6 + fs/xfs/xfs_file.c | 72 +++++++++++++++- fs/xfs/xfs_inode.h | 16 ++++ fs/xfs/xfs_ioctl.c | 8 -- fs/xfs/xfs_iops.c | 16 ++-- fs/xfs/xfs_pnfs.c | 16 ++-- fs/xfs/xfs_pnfs.h | 6 + fs/xfs/xfs_super.c | 20 ++-- include/linux/dax.h | 71 +++++++++++++++- include/linux/memremap.h | 25 ++---- include/linux/mm.h | 71 ++++++++++++---- kernel/Makefile | 3 - kernel/iomem.c | 167 +++++++++++++++++++++++++++++++++++++ kernel/memremap.c | 208 ++++++---------------------------------------- mm/Kconfig | 5 + mm/gup.c | 37 ++++++-- mm/hmm.c | 13 --- mm/swap.c | 3 - 24 files changed, 730 insertions(+), 297 deletions(-) create mode 100644 kernel/iomem.c

[PATCH] sched/schedutil: Don't set next_freq to UINT_MAX

by Viresh Kumar

The schedutil driver sets sg_policy->next_freq to UINT_MAX on certain occasions: - In sugov_start(), when the schedutil governor is started for a group of CPUs. - And whenever we need to force a freq update before rate-limit duration, which happens when: - there is an update in cpufreq policy limits. - Or when the utilization of DL scheduling class increases. In return, get_next_freq() doesn't return a cached next_freq value but instead recalculates the next frequency. This has some side effects though and may significantly delay a required increase in frequency. In sugov_update_single() we try to avoid decreasing frequency if the CPU has not been idle recently. Consider this scenario, the available range of frequencies for a CPU are from 800 MHz to 2.5 GHz and current frequency is 800 MHz. From one of the call paths sg_policy->need_freq_update is set to true and hence sg_policy->next_freq is set to UINT_MAX. Now if the CPU had been busy, next_f will always be less than UINT_MAX, whatever the value of next_f is. And so even when we wanted to increase the frequency, we will overwrite next_f with UINT_MAX and will not change the frequency eventually. This will continue until the time CPU stays busy. This isn't cross checked with any specific test cases, but rather based on general code review. Fix that by not resetting the sg_policy->need_freq_update flag from sugov_should_update_freq() but get_next_freq() and we wouldn't need to overwrite sg_policy->next_freq anymore.

Applied "spi: pxa2xx: Allow 64-bit DMA" to the spi tree

by Mark Brown

The patch spi: pxa2xx: Allow 64-bit DMA has been applied to the spi tree at https://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi.git All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted. You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail. Thanks, Mark >From efc4a13724b852ddaa3358402a8dec024ffbcb17 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko <andriy.shevchenko(a)linux.intel.com> Date: Thu, 19 Apr 2018 19:53:32 +0300 Subject: [PATCH] spi: pxa2xx: Allow 64-bit DMA Currently the 32-bit device address only is supported for DMA. However, starting from Intel Sunrisepoint PCH the DMA address of the device FIFO can be 64-bit. Change the respective variable to be compatible with DMA engine expectations, i.e. to phys_addr_t.

[PATCH] drm/vc4: Fix scaling of uni-planar formats

by Boris Brezillon

When using uni-planar formats (like RGB), the scaling parameters are stored in plane 0, not plane 1. Fixes: fc04023fafec ("drm/vc4: Add support for YUV planes.")
