+ mm-oom-fix-concurrent-munlock-and-oom-reaper-unmap.patch added to -mm tree

by akpm＠linux-foundation.org

The patch titled Subject: mm, oom: fix concurrent munlock and oom reaper unmap, v3 has been added to the -mm tree. Its filename is mm-oom-fix-concurrent-munlock-and-oom-reaper-unmap.patch This patch should soon appear at http://ozlabs.org/~akpm/mmots/broken-out/mm-oom-fix-concurrent-munlock-and-… and later at http://ozlabs.org/~akpm/mmotm/broken-out/mm-oom-fix-concurrent-munlock-and-… Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next and is updated there every 3-4 working days ------------------------------------------------------ From: David Rientjes <rientjes(a)google.com> Subject: mm, oom: fix concurrent munlock and oom reaper unmap, v3 Since exit_mmap() is done without the protection of mm->mmap_sem, it is possible for the oom reaper to concurrently operate on an mm until MMF_OOM_SKIP is set. This allows munlock_vma_pages_all() to concurrently run while the oom reaper is operating on a vma. Since munlock_vma_pages_range() depends on clearing VM_LOCKED from vm_flags before actually doing the munlock to determine if any other vmas are locking the same memory, the check for VM_LOCKED in the oom reaper is racy. This is especially noticeable on architectures such as powerpc where clearing a huge pmd requires serialize_against_pte_lookup(). If the pmd is zapped by the oom reaper during follow_page_mask() after the check for pmd_none() is bypassed, this ends up deferencing a NULL ptl or a kernel oops. Fix this by manually freeing all possible memory from the mm before doing the munlock and then setting MMF_OOM_SKIP. The oom reaper can not run on the mm anymore so the munlock is safe to do in exit_mmap(). It also matches the logic that the oom reaper currently uses for determining when to set MMF_OOM_SKIP itself, so there's no new risk of excessive oom killing. This issue fixes CVE-2018-1000200.

Applied "ASoC: cirrus: i2s: Fix LRCLK configuration" to the asoc tree

by Mark Brown

The patch ASoC: cirrus: i2s: Fix LRCLK configuration has been applied to the asoc tree at https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.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.

Applied "ASoC: cirrus: i2s: Fix {TX|RX}LinCtrlData setup" to the asoc tree

by Mark Brown

The patch ASoC: cirrus: i2s: Fix {TX|RX}LinCtrlData setup has been applied to the asoc tree at https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.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.

The only currently used bit (Left_Right_Justify) has different position. Fix this and simplify the whole setup taking into account the fact that both registers have zero default value. The practical effect of the above is repaired SND_SOC_DAIFMT_RIGHT_J support (currently unused).

FAILED: patch "[PATCH] tpm: self test failure should not cause suspend to fail" failed to apply to 4.4-stable tree

by gregkh＠linuxfoundation.org

The patch below does not apply to the 4.4-stable tree. If someone wants it applied there, or to any other stable or longterm tree, then please email the backport, including the original git commit id to <stable(a)vger.kernel.org>. thanks, greg k-h ------------------ original commit in Linus's tree ------------------ >From 0803d7befa15cab5717d667a97a66214d2a4c083 Mon Sep 17 00:00:00 2001 From: Chris Chiu <chiu(a)endlessm.com> Date: Tue, 20 Mar 2018 15:36:40 +0800 Subject: [PATCH] tpm: self test failure should not cause suspend to fail The Acer Acer Veriton X4110G has a TPM device detected as: tpm_tis 00:0b: 1.2 TPM (device-id 0xFE, rev-id 71) After the first S3 suspend, the following error appears during resume: tpm tpm0: A TPM error(38) occurred continue selftest Any following S3 suspend attempts will now fail with this error: tpm tpm0: Error (38) sending savestate before suspend PM: Device 00:0b failed to suspend: error 38 Error 38 is TPM_ERR_INVALID_POSTINIT which means the TPM is not in the correct state. This indicates that the platform BIOS is not sending the usual TPM_Startup command during S3 resume. >From this point onwards, all TPM commands will fail. The same issue was previously reported on Foxconn 6150BK8MC and Sony Vaio TX3. The platform behaviour seems broken here, but we should not break suspend/resume because of this. When the unexpected TPM state is encountered, set a flag to skip the affected TPM_SaveState command on later suspends.

[PATCH 0/3] v4.16 tpmdd backports

If the machine has a large amount of memory (more than 64G), the size of a memory block can span multiple sections. By mistake, during hotremove we set only the first section to offline state. The bug was discovered because kernel selftest started to fail: https://lkml.kernel.org/r/20180423011247.GK5563@yexl-desktop After commit, "mm/memory_hotplug: optimize probe routine". But, the bug is older than this commit. In this optimization we also added a check for sections to be in a proper state during hotplug operation.

[PATCH] drm/vc4: Make sure vc4_bo_{inc, dec}_usecnt() calls are balanced

by Boris Brezillon

Commit b9f19259b84d ("drm/vc4: Add the DRM_IOCTL_VC4_GEM_MADVISE ioctl") introduced a mechanism to mark some BOs as purgeable to allow the driver to drop them under memory pressure. In order to implement this feature we had to add a mechanism to mark BOs as currently used by a piece of hardware which materialized through the ->usecnt counter. Plane code is supposed to increment usecnt when it attaches a BO to a plane and decrement it when it's done with this BO, which was done in the ->prepare_fb() and ->cleanup_fb() hooks. The problem is, async page flip logic does not go through the regular atomic update path, and ->prepare_fb() and ->cleanup_fb() are not called in this case. Fix that by manually calling vc4_bo_{inc,dec}_usecnt() in the async-page-flip path. Note that all this should go away as soon as we get generic async page flip support in the core, in the meantime, this fix should do the trick.

[PATCH 1/3] ioremap: Update pgtable free interfaces with addr

by Toshi Kani

From: Chintan Pandya <cpandya(a)codeaurora.org> This patch ("mm/vmalloc: Add interfaces to free unmapped page table") adds following 2 interfaces to free the page table in case we implement huge mapping. pud_free_pmd_page() and pmd_free_pte_page() Some architectures (like arm64) needs to do proper TLB maintanance after updating pagetable entry even in map. Why ? Read this, https://patchwork.kernel.org/patch/10134581/ Pass 'addr' in these interfaces so that proper TLB ops can be performed.

[PATCH for-next 0/6] IB/hfi1,rdmavt: Fixes for the 4.17 RC

by Dennis Dalessandro

Hi Jason and Doug, Here are 6 patches that might make the bar for RC. The first patch fixes something that came in pretty recently, I beleive 4.13. The second patch is trivial, but does modify user visible text. Patch 3 looks large but it's mostly comments. It just moves code. Patch 4 is also pretty simple. The last two patches fix memory leaks. If you don't think these pass muster for RC please carry over to for-next. --- Michael J. Ruhl (1): IB/hfi1 Use correct type for num_user_context Mike Marciniszyn (2): IB/hfi1: Fix handling of FECN marked multicast packet IB/hfi1: Fix loss of BECN with AHG Sebastian Sanchez (3): IB/hfi1: Fix NULL pointer dereference when invalid num_vls is used IB/{hfi1,rdmavt}: Fix memory leak in hfi1_alloc_devdata() upon failure IB/hfi1: Fix memory leak in exception path in get_irq_affinity() drivers/infiniband/hw/hfi1/affinity.c | 11 +++---- drivers/infiniband/hw/hfi1/driver.c | 19 ++++++++++--- drivers/infiniband/hw/hfi1/hfi.h | 8 +++-- drivers/infiniband/hw/hfi1/init.c | 43 ++++++++++++++++++++-------- drivers/infiniband/hw/hfi1/pcie.c | 3 -- drivers/infiniband/hw/hfi1/platform.c | 1 + drivers/infiniband/hw/hfi1/qsfp.c | 2 + drivers/infiniband/hw/hfi1/ruc.c | 50 ++++++++++++++++++++++++++------- drivers/infiniband/hw/hfi1/ud.c | 6 ++-- 9 files changed, 101 insertions(+), 42 deletions(-) -- -Denny
