[PATCH v2] rpmsg: smd: do not use mananged resources for endpoints and channels

by Srinivas Kandagatla

All the managed resources would be freed by the time release function is invoked. Handling such memory in qcom_smd_edge_release() would do bad things. Found this issue while testing Audio usecase where the dsp is started up and shutdown in a loop. This patch fixes this issue by using simple kzalloc for allocating channel->name and channel which is then freed in qcom_smd_edge_release(). Without this patch restarting a remoteproc would crash the system.

[PATCH for-rc 0/2] IB/hfi1: Fixes for rc or next if too late

by Dennis Dalessandro

Hi Doug and Jason, We have two more late breaking fix up patches. The DMA_RTAIL fix is the more serious of the two. I realize we are at the tail end of 4.17 so I would not be against holding off till 4.18 for these, but if there is another rdma pull request we may want to tack these on. --- Kaike Wan (1): IB/hfi1: Ensure VL index is within bounds Mike Marciniszyn (1): IB/hfi1: Fix user context tail allocation for DMA_RTAIL drivers/infiniband/hw/hfi1/chip.c | 8 ++++---- drivers/infiniband/hw/hfi1/file_ops.c | 2 +- drivers/infiniband/hw/hfi1/init.c | 9 ++++----- drivers/infiniband/hw/hfi1/sdma.c | 12 +++--------- 4 files changed, 12 insertions(+), 19 deletions(-) -- -Denny

[PATCH 00/29] objtool sync up for the stable 4.9.y tree

by Greg Kroah-Hartman

There are pros and cons of dealing with tools in the kernel directory. The pros are the fact that development happens fast, and new features can be added to the kernel and the tools at the same times. The cons are when dealing with backported kernel patches, it can be necessary to backport parts of the tool changes as well. For 4.9.y so far, we have backported individual patches. That quickly breaks down when there are minor differences between how backports were handled, so grabbing 40+ patch long series can be difficult, not impossible, but really frustrating to attempt. To help mitigate this mess, this patch series works to sync up the objtool code with the version that is currently in 4.14.47. This required a number of objtool old patches to be backported, a single big "sync the world" patch, and a lot of include file updates to get everything all working properly as well as some minor fixes for build warnings. And at the end of this series, is a set of backported objtool patches for gcc-8 that was the main reason this whole patch series was created. They applied just fine, being the identical version that goes into the 4.14.y stable tree, so it feels like the backport was successful. This has survivied my limited testing, and as the codebase is identical to 4.14.47, I'm pretty comfortable dropping this big change in here in 4.9.y. Hopefully all goes well... If anyone has any objections to this patch series, or finds anything I messed up on, please let me know. thanks, greg k-h Arnaldo Carvalho de Melo (11): tools include: Introduce linux/compiler-gcc.h tools include: Adopt __compiletime_error tools include: Introduce atomic_cmpxchg_{relaxed,release}() tools include: Add UINT_MAX def to kernel.h tools include: Adopt kernel's refcount.h tools include uapi: Grab copies of stat.h and fcntl.h tools include: Introduce linux/bug.h, from the kernel sources tools include: Adopt __same_type() and __must_be_array() from the kernel tools include: Move ARRAY_SIZE() to linux/kernel.h tools include: Drop ARRAY_SIZE() definition from linux/hashtable.h tools include: Include missing headers for fls() and types in linux/log2.h Greg Kroah-Hartman (4): objtool: sync up with the 4.14.47 version of objtool perf/tools: header file sync up objtool: header file sync-up x86/xen: Add unwind hint annotations to xen_setup_gdt Jiri Olsa (3): tools lib: Add for_each_clear_bit macro perf tools: Force fixdep compilation at the start of the build perf tools: Move headers check into bash script Josh Poimboeuf (8): objtool: Improve detection of BUG() and other dead ends objtool: Move checking code to check.c objtool: Support GCC 8's cold subfunctions objtool: Support GCC 8 switch tables objtool: Detect RIP-relative switch table references objtool: Detect RIP-relative switch table references, part 2 objtool: Fix "noreturn" detection for recursive sibling calls objtool, x86: Add several functions and files to the objtool whitelist Matthew Wilcox (2): tools: add more bitmap functions radix tree test suite: Remove types.h Michael S.

Applied "ASoC: dapm: delete dapm_kcontrol_data paths list before freeing it" to the asoc tree

by Mark Brown

The patch ASoC: dapm: delete dapm_kcontrol_data paths list before freeing it 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.

[PATCH] mfd: intel-lpss: Fix Intel Cannon Lake LPSS I2C input clock

by Jarkko Nikula

Intel Cannon Lake PCH has much higher 216 MHz input clock to LPSS I2C than Sunrisepoint which uses 120 MHz. Preliminary information was that both share the same clock rate but actual silicon implements elevated rate for better support for 3.4 MHz high-speed I2C. This incorrect input clock rate results too high I2C bus clock in case ACPI doesn't provide tuned I2C timing parameters since I2C host controller driver calculates them from input clock rate. Fix this by using the correct rate. We still share the same 230 ns SDA hold time value than Sunrisepoint.

[PATCH] drm/qxl: Call qxl_bo_unref outside atomic context

by Jeremy Cline

"qxl_bo_unref" may sleep, but calling "qxl_release_map" causes "preempt_disable()" to be called and "preempt_enable()" isn't called until "qxl_release_unmap" is used. Move the call to "qxl_bo_unref" out from in between the two to avoid sleeping from an atomic context. This issue can be demonstrated on a kernel with CONFIG_LOCKDEP=y by creating a VM using QXL, using a desktop environment using Xorg, then moving the cursor on or off a window.

Please add commit 145e1a71e090 to stable

by Hugh Dickins

Please add 4.17 commit 145e1a71e090575c74969e3daa8136d1e5b99fc8 ("mm: fix the NULL mapping case in __isolate_lru_page()") to the 4.16, 4.14, 4.9, 4.4, 3.18 and 3.2 stable kernel trees. Two things happened after I'd sent it to Andrew without a stable tag: 1. Ivan posted an equivalent patch: after painstaking bisection, he had found the fixed commit to be what was causing strange blocking (surprising to the rest of us, we had imagined it just suboptimal). 2. The fixed commit arrived in five stable kernel releases (presumably arriving there by auto selection: which will in due course pick up this fix to it, but I don't know its cadence). Thanks, Hugh From: Hugh Dickins <hughd(a)google.com> Date: Fri, 1 Jun 2018 16:50:50 -0700 George Boole would have noticed a slight error in 4.16 commit 69d763fc6d3a ("mm: pin address_space before dereferencing it while isolating an LRU page"). Fix it, to match both the comment above it, and the original behaviour. Although anonymous pages are not marked PageDirty at first, we have an old habit of calling SetPageDirty when a page is removed from swap cache: so there's a category of ex-swap pages that are easily migratable, but were inadvertently excluded from compaction's async migration in 4.16.

[PATCH] x86/platform/uv/BAU: gracefully disable BAU during panic

by Andrew Banman

When panic happens while BAU is active there is a chance that outstanding broadcasts tie up BAU resources enough to cause timeouts in the UV ASIC. These timeouts are hardware errors that immediately bring down the system, preventing kdump from completing. Add uv_bau_crash_shutdown() to bring BAU to quiescence during panic before continuing with the native crash shutdown. Assign uv_bau_crash_shutdown to machine_ops during init.

This is an incorrect error code, there is nothing that will make this GID entry valid again in bounded time. Some user space tools fail incorrectly if EAGAIN is returned here, and this represents a small ABI change from earlier kernels. The first patch in the Fixes list makes entries that were valid before to become invalid, allowing this code to trigger, while the second patch in the Fixes list introduced the wrong EAGAIN.

[PATCH v3] net/mlx4_en: fix potential use-after-free with dma_unmap_page

by Sarah Newman

[ Not relevant upstream, therefore no upstream commit. ] To fix, unmap the page as soon as possible. When swiotlb is in use, calling dma_unmap_page means that the original page mapped with dma_map_page must still be valid, as swiotlb will copy data from its internal cache back to the originally requested DMA location. When GRO is enabled, before this patch all references to the original frag may be put and the page freed before dma_unmap_page in mlx4_en_free_frag is called. It is possible there is a path where the use-after-free occurs even with GRO disabled, but this has not been observed so far. The bug can be trivially detected by doing the following: * Compile the kernel with DEBUG_PAGEALLOC * Run the kernel as a Xen Dom0 * Leave GRO enabled on the interface * Run a 10 second or more test with iperf over the interface. This bug was likely introduced in commit 4cce66cdd14a ("mlx4_en: map entire pages to increase throughput"), first part of u3.6. It was incidentally fixed in commit 34db548bfb95 ("mlx4: add page recycling in receive path"), first part of v4.12. This version applies to the v4.9 series.

[PATCH 0/2] 4.14 long term stable ZBC fixes

by Damien Le Moal

Patch 0aa3fdb8b3a6 ("scsi: sd_zbc: Fix potential memory leak") was added in 4.16 and 4.15 stable but did not make it to long term stable 4.14 (as far as I can tell). Patch ccce20fc7968 ("scsi: sd_zbc: Avoid that resetting a zone fails sporadically") is included in 4.16 but does not apply to 4.15 stable nor to 4.14 long term stable and requires extensive modifications. This small series provides a backport of both patches against 4.14. Please consider these patches for inclusion in this long term stable kernel.

From: Yoshihiro Shimoda <yoshihiro.shimoda.uh(a)renesas.com> commit d9f5efade2cfd729138a7cafb46d01044da40f5e upstream This patch fixes an issue that list_for_each_entry() in usb_dmac_chan_terminate_all() is possible to cause endless loop because this will move own desc to the desc_freed.

[PATCH 0/6] Fix R-Car I2C data byte sent twice issue

by Fabrizio Castro

Hello Greg, this series fixes an issue with the I2C driver of the Renesas R-Car and RZ/G1 family of chips. The issue is clearly visible with the CIP kernel (4.4) running on a iwg20d board from iWave due to the way the bq32000 driver/device is interacting with the I2C driver/controller. In the stable kernel (4.4) there is no support for the iwg20d, I tried to replicate the same problem on a Koelsch board with no success, but the problem is there. Do you think this series is suitable for (4.4) stable considering I can't reproduce the problem on the Koelsch board? This patches apply on top of 4.4.133.

stable release patches (gcc, clang)

by Guenter Roeck

Hi Greg, the following are some more patches for stable releases. I collected the following clang patches from chromeos-4.14. They are not really needed to build x86_64:defconfig in v4.14.y with clang (5.0), but they do fix a couple of build warnings if the respective drivers are enabled. I'll leave it up to you if you want to apply them or not. I did make sure that defconfig and allmodconfig still build using gcc with the patches applied. df16aaac26e9 kbuild: clang: remove crufty HOSTCFLAGS cad9946c2a43 drm/i915: Always sanity check engine state upon idling 531beb067c61 dma-buf: remove redundant initialization of sg_table 42b5122e828a drm/amd/powerplay: Fix enum mismatch fb239c1209bb rtlwifi: rtl8192cu: Remove variable self-assignment in rf.c 271ef65b5882 ASoC: Intel: sst: remove redundant variable dma_dev_name d3b56c566d4b platform/chrome: cros_ec_lpc: remove redundant pointer request 0a5f41767444 kbuild: clang: disable unused variable warnings The following patch is needed in v4.4.y to be able to build arm:footbridge_defconfig with gcc 7.3.0. c9bd28233b6d irda: fix overly long udelay() Thanks, Guenter

[patch 1/2] mm/huge_memory.c: __split_huge_page() use atomic ClearPageDirty()

by akpm＠linux-foundation.org

From: Hugh Dickins <hughd(a)google.com> Subject: mm/huge_memory.c: __split_huge_page() use atomic ClearPageDirty() Swapping load on huge=always tmpfs (with khugepaged tuned up to be very eager, but I'm not sure that is relevant) soon hung uninterruptibly, waiting for page lock in shmem_getpage_gfp()'s find_lock_entry(), most often when "cp -a" was trying to write to a smallish file. Debug showed that the page in question was not locked, and page->mapping NULL by now, but page->index consistent with having been in a huge page before. Reproduced in minutes on a 4.15 kernel, even with 4.17's 605ca5ede764 ("mm/huge_memory.c: reorder operations in __split_huge_page_tail()") added in; but took hours to reproduce on a 4.17 kernel (no idea why). The culprit proved to be the __ClearPageDirty() on tails beyond i_size in __split_huge_page(): the non-atomic __bitoperation may have been safe when 4.8's baa355fd3314 ("thp: file pages support for split_huge_page()") introduced it, but liable to erase PageWaiters after 4.10's 62906027091f ("mm: add PageWaiters indicating tasks are waiting for a page bit").

[PATCH v4.9.y 0/2] arm64: prevent boot-time crashes when detecting local features

by Mark Rutland

Marc reported that v4.9.y hung at boot time on his GICv3 system, since the spectre backports. This is because the errata detection logic tries to enable a static key in the secondary bringup path, before the secondary CPU has configured its GICv3 CPU interface, causing it to blow up when it tries to IPI the other CPUs. This affects any local cpu feature detection in systems with heterogeneous CPUs. Some prior rework upstream moved this out of the secondary bringup path, which avoids the issue, so this series backports said rework. Thanks, Mark.

[PATCH] Revert "ima: limit file hash setting by user to fix and log modes"

by Mike Rapoport

Hi, On a system that has IMA appraisal enabled it is impossible to create security.ima extended attribute files that contain IMA hash. For instance, consider the following use case: 1) extract application files to a staging area as non root user 2) verify that installation is correct 3) create IMA extended attributes for the installed files 4) move the files to their destination 5) change the files ownership to root With the longterm kernels 4.4.x and 4.9.x step 3 will fail. The issues is fixed in upstream kernels by the commit f5acb3dcba1ffb7f0b8cbb9dba61500eea5d610b ("Revert "ima: limit file hash setting by user to fix and log modes"), with the patch also quoted below. -- Sincerely yours, Mike. >From f5acb3dcba1ffb7f0b8cbb9dba61500eea5d610b Mon Sep 17 00:00:00 2001 From: Mimi Zohar <zohar(a)linux.vnet.ibm.com> Date: Wed, 2 Nov 2016 09:14:16 -0400 Subject: [PATCH] Revert "ima: limit file hash setting by user to fix and log modes" Userspace applications have been modified to write security xattrs, but they are not context aware. In the case of security.ima, the security xattr can be either a file hash or a file signature. Permitting writing one, but not the other requires the application to be context aware. In addition, userspace applications might write files to a staging area, which might not be in policy, and then change some file metadata (eg. owner) making it in policy. As a result, these files are not labeled properly. This reverts commit c68ed80c97d9720f51ef31fe91560fdd1e121533, which prevents writing file hashes as security.ima xattrs.

[PATCH 0/1] Fix for xfs agfl wrap crash for stable kernels

by Dave Chiluk

When moving xfs volumes between kernels that have 96f859d52 and don't have 96f859d52, there is potential for a filesystem crash if the agfl has wrapped (flfirst > fllast). Depending on which filesystem this is this can take down the whole machine. Such is the case when upgrading from the stock Centos 7 3.13 to the kernel.org stable kernels (via elrepo). Another possible common boundary cross I noticed was early Ubuntu kernel v4.4 to recent v4.4. We've been hitting this crash roughly once a week in our cloud, and it has produced the below stack trace. The solution prefers to reset the agfl and leak a few blocks instead of shutting down the filesystem. The leaked blocks can be recovered using a xfs_repair. The attached patch is a backport of a27ba2607 due to a78ee256c. It is intended for and tested on the v4.4 stream, but should apply to all kernels that lack upstream a78ee256c.

Please apply this commit to v4.14.y: de0aa7b2f97d ("PCI: hv: Fix 2 hang issues in hv_compose_msi_msg()")

by Dexuan Cui

Hi, The patch has been in v4.15.y and v4.16.y, but not in v4.14.y: de0aa7b2f97d ("PCI: hv: Fix 2 hang issues in hv_compose_msi_msg()") The second issue described in the changelog of the commit can happen to v4.14.y too. Since the v4.14.y is a longterm kernel, we should apply the patch to it. I have verified the commit can be cherry-picked cleanly. Thanks! -- Dexuan

However on Power-9 with radix mode we don't have Storage-Segments that we can prefault. Also prefaulting process Pages will be too costly and fine-grained. Hence, since the prefaulting mechanism doesn't makes sense of radix-mode, this patch updates prefault_mode_store() to not allow any other value apart from CXL_PREFAULT_NONE when radix mode is enabled.

[PATCH] vmw_balloon: fixing double free when batching mode is off

by Nadav Amit

From: Gil Kupfer <gilkup(a)gmail.com> The balloon.page field is used for two different purposes if paging is on or off. If batching is on, the field point to the page which is used to communicate with with the hypervisor. If it is off, balloon.page points to the page that is about to be (un)locked. Unfortunately, this dual-purpose of the field introduced a bug: when the balloon is popped (e.g., when the machine is reset or the balloon driver is explicitly removed), the balloon driver frees, unconditionally, the page that is held in balloon.page. As a result, if batching is disabled, this leads to double freeing the last page that is sent to the hypervisor. batching and pointer to current page otherwise. When the balloon is popped (during reset or rmmode), it tries to free the communication page. If batching is disabled, this leads to double free of the last page sent to the backend. The following error occurs during rmmod when kernel checkers are on, and the balloon is not empty: [ 42.307653] ------------[ cut here ]------------ [ 42.307657] Kernel BUG at ffffffffba1e4b28 [verbose debug info unavailable] [ 42.307720] invalid opcode: 0000 [#1] SMP DEBUG_PAGEALLOC [ 42.312512] Modules linked in: vmw_vsock_vmci_transport vsock ppdev joydev vmw_balloon(-) input_leds serio_raw vmw_vmci parport_pc shpchp parport i2c_piix4 nfit mac_hid autofs4 vmwgfx drm_kms_helper hid_generic syscopyarea sysfillrect usbhid sysimgblt fb_sys_fops hid ttm mptspi scsi_transport_spi ahci mptscsih drm psmouse vmxnet3 libahci mptbase pata_acpi [ 42.312766] CPU: 10 PID: 1527 Comm: rmmod Not tainted 4.12.0+ #5 [ 42.312803] Hardware name: VMware, Inc.

[PATCH V4] scsi: hpsa: drop shutdown callback

by Sinan Kaya

'Commit cc27b735ad3a ("PCI/portdrv: Turn off PCIe services during shutdown")' has been added to kernel to shutdown pending PCIe port service interrupts during reboot so that a newly started kexec kernel wouldn't observe pending interrupts. pcie_port_device_remove() is disabling the root port and switches by calling pci_disable_device() after all PCIe service drivers are shutdown. This has been found to cause crashes on HP DL360 Gen9 machines during reboot due to hpsa driver not clearing the bus master bit during the shutdown procedure by calling pci_disable_device(). Disable device as part of the shutdown sequence.

[PATCH v12 1/5] ioremap: Update pgtable free interfaces with addr

by Chintan Pandya

From: Chintan Pandya <cpandya(a)codeaurora.org> The following kernel panic was observed on ARM64 platform due to a stale TLB entry. 1. ioremap with 4K size, a valid pte page table is set. 2. iounmap it, its pte entry is set to 0. 3. ioremap the same address with 2M size, update its pmd entry with a new value. 4. CPU may hit an exception because the old pmd entry is still in TLB, which leads to a kernel panic. Commit b6bdb7517c3d ("mm/vmalloc: add interfaces to free unmapped page table") has addressed this panic by falling to pte mappings in the above case on ARM64. To support pmd mappings in all cases, TLB purge needs to be performed in this case on ARM64. Add a new arg, 'addr', to pud_free_pmd_page() and pmd_free_pte_page() so that TLB purge can be added later in seprate patches.

Linux 3.2.102

by Ben Hutchings

I'm announcing the release of the 3.2.102 kernel. All users of the 3.2 kernel series should upgrade. However, this is likely to be the final stable update for 3.2.

patch "NFC: pn533: don't send USB data off of the stack" added to usb-next

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled NFC: pn533: don't send USB data off of the stack to my usb git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git in the usb-next branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will also be merged in the next major kernel release during the merge window. If you have any questions about this process, please let me know. >From dbafc28955fa6779dc23d1607a0fee5e509a278b Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman <gregkh(a)linuxfoundation.org> Date: Sun, 20 May 2018 15:19:46 +0200 Subject: NFC: pn533: don't send USB data off of the stack It's amazing that this driver ever worked, but now that x86 doesn't allow USB data to be sent off of the stack, it really does not work at all. Fix this up by properly allocating the data for the small "commands" that get sent to the device off of the stack.

[PATCH] MIPS: ptrace: Fix PTRACE_PEEKUSR requests for 64-bit FGRs

by Maciej W. Rozycki

Use 64-bit accesses for 64-bit floating-point general registers with PTRACE_PEEKUSR, removing the truncation of their upper halves in the FR=1 mode, caused by commit bbd426f542cb ("MIPS: Simplify FP context access"), which inadvertently switched them to using 32-bit accesses. The PTRACE_POKEUSR side is fine as it's never been broken and continues using 64-bit accesses.

[PATCH] MIPS: prctl: Disallow FRE without FR with PR_SET_FP_MODE requests

by Maciej W. Rozycki

Having PR_FP_MODE_FRE (i.e. Config5.FRE) set without PR_FP_MODE_FR (i.e. Status.FR) is not supported as the lone purpose of Config5.FRE is to emulate Status.FR=0 handling on FPU hardware that has Status.FR=1 hardwired[1][2]. Also we do not handle this case elsewhere, and assume throughout our code that TIF_HYBRID_FPREGS and TIF_32BIT_FPREGS cannot be set both at once for a task, leading to inconsistent behaviour if this does happen. Return unsuccessfully then from prctl(2) PR_SET_FP_MODE calls requesting PR_FP_MODE_FRE to be set with PR_FP_MODE_FR clear. This corresponds to modes allowed by `mips_set_personality_fp'.

[PATCH 03/18] drm/amd/display: Make atomic-check validate underscan changes

by Harry Wentland

From: David Francis <David.Francis(a)amd.com> When the underscan state was changed, atomic-check was triggering a validation but passing the old underscan values. This change adds a somewhat hacky check in dm_update_crtcs_state that will update the stream if old and newunderscan values are different.

[PATCH 1/3] orangefs: set i_size on new symlink

by Martin Brandenburg

As long as a symlink inode remains in-core, the destination (and therefore size) will not be re-fetched from the server, as it cannot change. The original implementation of the attribute cache assumed that setting the expiry time in the past was sufficient to cause a re-fetch of all attributes on the next getattr. That does not work in this case. The bug manifested itself as follows. When the command sequence touch foo; ln -s foo bar; ls -l bar is run, the output was lrwxrwxrwx. 1 fedora fedora 4906 Apr 24 19:10 bar -> foo However, after a re-mount, ls -l bar produces lrwxrwxrwx. 1 fedora fedora 3 Apr 24 19:10 bar -> foo After this commit, even before a re-mount, the output is lrwxrwxrwx. 1 fedora fedora 3 Apr 24 19:10 bar -> foo Reported-by: Becky Ligon <ligon(a)clemson.edu> Signed-off-by: Martin Brandenburg <martin(a)omnibond.com> Fixes: 71680c18c8f2 ("orangefs: Cache getattr results.")

[PATCH v2] libata: Drop SanDisk SD7UB3Q*G1001 NOLPM quirk

by Hans de Goede

Commit 184add2ca23c ("libata: Apply NOLPM quirk for SanDisk SD7UB3Q*G1001 SSDs") disabled LPM for SanDisk SD7UB3Q*G1001 SSDs. This has lead to several reports of users of that SSD where LPM was working fine and who know have a significantly increased idle power consumption on their laptops. Likely there is another problem on the T450s from the original reporter which gets exposed by the uncore reaching deeper sleep states (higher PC-states) due to LPM being enabled. The problem as reported, a hardfreeze about once a day, already did not sound like it would be caused by LPM and the reports of the SSD working fine confirm this. The original reporter is ok with dropping the quirk. A X250 user has reported the same hard freeze problem and for him the problem went away after unrelated updates, I suspect some GPU driver stack changes fixed things. TL;DR: The original reporters problem were triggered by LPM but not an LPM issue, so drop the quirk for the SSD in question.

[PATCH] libata: Drop SanDisk SD7UB3Q*G1001 NOLPM quirk

by Hans de Goede

Commit 184add2ca23c ("libata: Apply NOLPM quirk for SanDisk SD7UB3Q*G1001 SSDs") disabled LPM for SanDisk SD7UB3Q*G1001 SSDs. This has lead to several reports of users of that SSD where LPM was working fine and who know have a significantly increased idle power consumption on their laptops. Likely there is another problem on the T450s from the original reporter which gets exposed by the uncore reaching deeper sleep states (higher PC-states) due to LPM being enabled. The problem as reported, a hardfreeze about once a day, already did not sound like it would be caused by LPM and the reports of the SSD working fine confirm this. The original reporter is ok with dropping the quirk. A X250 user has reported the same hard freeze problem and for him the problem went away after unrelated updates, I suspect some GPU driver stack changes fixed things. TL;DR: The original reporters problem were triggered by LPM but not an LPM issue, so drop the quirk for the SSD in question.

Fix this up by properly allocating the data for the small "commands" that get sent to the device off of the stack. We do this for one command by having a whole urb just for ack messages, as they can be submitted in interrupt context, so we can not use usb_bulk_msg(). But the poweron command can sleep (and does), so use usb_bulk_msg() for that transfer.

[PATCH v4] rtc: sun6i: Fix bit_idx value for clk_register_gate

by Jagan Teki

From: Michael Trimarchi <michael(a)amarulasolutions.com> clk-gate core will take bit_idx through clk_register_gate and then do clk_gate_ops by using BIT(bit_idx), but rtc-sun6i is passing bit_idx as BIT(bit_idx) it becomes BIT(BIT(bit_idx) which is wrong and eventually external gate clock is not enabling.

Its filename is mm-huge_memoryc-__split_huge_page-use-atomic-clearpagedirty.patch This patch should soon appear at http://ozlabs.org/~akpm/mmots/broken-out/mm-huge_memoryc-__split_huge_page-… and later at http://ozlabs.org/~akpm/mmotm/broken-out/mm-huge_memoryc-__split_huge_page-… 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: Hugh Dickins <hughd(a)google.com> Subject: mm/huge_memory.c: __split_huge_page() use atomic ClearPageDirty() Swapping load on huge=always tmpfs (with khugepaged tuned up to be very eager, but I'm not sure that is relevant) soon hung uninterruptibly, waiting for page lock in shmem_getpage_gfp()'s find_lock_entry(), most often when "cp -a" was trying to write to a smallish file. Debug showed that the page in question was not locked, and page->mapping NULL by now, but page->index consistent with having been in a huge page before. Reproduced in minutes on a 4.15 kernel, even with 4.17's 605ca5ede764 ("mm/huge_memory.c: reorder operations in __split_huge_page_tail()") added in; but took hours to reproduce on a 4.17 kernel (no idea why). The culprit proved to be the __ClearPageDirty() on tails beyond i_size in __split_huge_page(): the non-atomic __bitoperation may have been safe when 4.8's baa355fd3314 ("thp: file pages support for split_huge_page()") introduced it, but liable to erase PageWaiters after 4.10's 62906027091f ("mm: add PageWaiters indicating tasks are waiting for a page bit").

[PATCH v3 3/3] x86/mm: add TLB purge to free pmd/pte page interfaces

by Toshi Kani

ioremap() calls pud_free_pmd_page() / pmd_free_pte_page() when it creates a pud / pmd map. The following preconditions are met at their entry. - All pte entries for a target pud/pmd address range have been cleared. - System-wide TLB purges have been peformed for a target pud/pmd address range. The preconditions assure that there is no stale TLB entry for the range. Speculation may not cache TLB entries since it requires all levels of page entries, including ptes, to have P & A-bits set for an associated address. However, speculation may cache pud/pmd entries (paging-structure caches) when they have P-bit set. Add a system-wide TLB purge (INVLPG) to a single page after clearing pud/pmd entry's P-bit.

[Linux-stable-mirror] [PATCH 1/2] bdi: make sure congestion states are clear on free

by Tejun Heo

FUSE has a bug where it fails to clear congestion states if a connection gets aborted while congested, which can leave nr_wb_congested[] stuck until reboot causing wait_iff_congested() to wait spuriously. While the bdi owner, FUSE, is primarily responsible for clearing congestion states before destroying bdi_writebacks, bdi layer can ensure that congestion states are not leaked beyond bdi_writeback lifecycle.

[PATCH 3/4] branch-check: fix long->int truncation when profiling branches

by Mikulas Patocka

The function __builtin_expect returns long type (see the gcc documentation), and so do macros likely and unlikely. Unfortunatelly, when CONFIG_PROFILE_ANNOTATED_BRANCHES is selected, the macros likely and unlikely expand to __branch_check__ and __branch_check__ truncates the long type to int. This unintended truncation may cause bugs in various kernel code (we found a bug in dm-writecache because of it), so it's better to fix __branch_check__ to return long.

The changes are to make sure to check the operation status. Actually the flash write and erase error behavior is caused on our products. The flash is Macronix flash device MX29GL512FHT2I-11G used by our products. The patch series was separated for changes of flash write and erase. Since those were not depended each other at the time. But by additional changes the changes are related more as same way currently. So combine patch series for the flash write and erase changes as v6.

[PATCH 4.9] powerpc/64s: Clear PCR on boot

by Michael Neuling

Clear the PCR (Processor Compatibility Register) on boot to ensure we are not running in a compatibility mode. We've seen this cause problems when a crash (and kdump) occurs while running compat mode guests. The kdump kernel then runs with the PCR set and causes problems. The symptom in the kdump kernel (also seen in petitboot after fast-reboot) is early userspace programs taking sigills on newer instructions (seen in libc).

[PATCH] ALSA: hda/realtek - Enable mic-mute hotkey for several Lenovo AIOs

by Hui Wang

We have several Lenovo AIOs like M810z, M820z and M920z, they have the same design for mic-mute hotkey and led and they use the same codec with the same pin configuration, so use the pin conf table to apply fix to all of them.

[PATCH V2] PCI/portdrv: do not disable device on reboot/shutdown

by Sinan Kaya

'Commit cc27b735ad3a ("PCI/portdrv: Turn off PCIe services during shutdown")' has been added to kernel to shutdown pending PCIe port service interrupts during reboot so that a newly started kexec kernel wouldn't observe pending interrupts. pcie_port_device_remove() is disabling the root port and switches by calling pci_disable_device() after all PCIe service drivers are shutdown. pci_disable_device() has a much wider impact then port service itself and it prevents all inbound transactions to reach to the system and impacts the entire PCI traffic behind the bridge. Issue is that pcie_port_device_remove() doesn't maintain any coordination with the rest of the PCI device drivers in the system before clearing the bus master bit. This has been found to cause crashes on HP DL360 Gen9 machines during reboot. Besides, kexec is already clearing the bus master bit in pci_device_shutdown() after all PCI drivers are removed.

[PATCH V3 1/2] PCI: Try to clean up resources via remove if shutdown doesn't exist

by Sinan Kaya

It is up to a driver to implement shutdown() callback. If shutdown() callback is not implemented, PCI device can have pending interrupt and even do DMA transactions while the system is going down. If kexec is in use, this can damage the newly booting kexec kernel or even prevent it from booting altogether. Fallback to calling the remove() callback if shutdown() isn't implemented for a given driver.

The patch titled Subject: ocfs2: fix a misuse a of brelse after failing ocfs2_check_dir_entry has been added to the -mm tree. Its filename is ocfs2-fix-a-misuse-a-of-brelse-after-failing-ocfs2_check_dir_entry.patch This patch should soon appear at http://ozlabs.org/~akpm/mmots/broken-out/ocfs2-fix-a-misuse-a-of-brelse-aft… and later at http://ozlabs.org/~akpm/mmotm/broken-out/ocfs2-fix-a-misuse-a-of-brelse-aft… 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: Changwei Ge <ge.changwei(a)h3c.com> Subject: ocfs2: fix a misuse a of brelse after failing ocfs2_check_dir_entry Somehow, file system metadata was corrupted, which causes ocfs2_check_dir_entry() to fail in function ocfs2_dir_foreach_blk_el(). According to the original design intention, if above happens we should skip the problematic block and continue to retrieve dir entry. But there is obviouse misuse of brelse around related code. After failure of ocfs2_check_dir_entry(), currunt code just moves to next position and uses the problematic buffer head again and again during which the problematic buffer head is released for multiple times. I suppose, this a serious issue which is long-lived in ocfs2. This may cause other file systems which is also used in a the same host insane. So we should also consider about bakcporting this patch into linux -stable.

And __vmalloc_node_range() gives you any address you ask. It doesn't have to be an address in [VMALLOC_START, VMALLOC_END] range. That's also how the module_alloc()/module_memfree() works on architectures that have designated area for modules.

[merged] revert-ipc-shm-fix-shmat-mmap-nil-page-protection.patch removed from -mm tree

by akpm＠linux-foundation.org

The patch titled Subject: Revert "ipc/shm: Fix shmat mmap nil-page protection" has been removed from the -mm tree. Its filename was revert-ipc-shm-fix-shmat-mmap-nil-page-protection.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Davidlohr Bueso <dave(a)stgolabs.net> Subject: Revert "ipc/shm: Fix shmat mmap nil-page protection" Patch series "ipc/shm: shmat() fixes around nil-page". These patches fix two issues reported[1] a while back by Joe and Andrea around how shmat(2) behaves with nil-page. The first reverts a commit that it was incorrectly thought that mapping nil-page (address=0) was a no no with MAP_FIXED. This is not the case, with the exception of SHM_REMAP; which is address in the second patch. I chose two patches because it is easier to backport and it explicitly reverts bogus behaviour. Both patches ought to be in -stable and ltp testcases need updated (the added testcase around the cve can be modified to just test for SHM_RND|SHM_REMAP). [1] lkml.kernel.org/r/20180430172152.nfa564pvgpk3ut7p@linux-n805 This patch (of 2): 95e91b831f87 ("ipc/shm: Fix shmat mmap nil-page protection") worked on the idea that we should not be mapping as root addr=0 and MAP_FIXED. However, it was reported that this scenario is in fact valid, thus making the patch both bogus and breaks userspace as well. For example X11's libint10.so relies on shmat(1, SHM_RND) for lowmem initialization[1].

[merged] idr-fix-invalid-ptr-dereference-on-item-delete.patch removed from -mm tree

by akpm＠linux-foundation.org

The patch titled Subject: idr: fix invalid ptr dereference on item delete has been removed from the -mm tree. Its filename was idr-fix-invalid-ptr-dereference-on-item-delete.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Matthew Wilcox <mawilcox(a)microsoft.com> Subject: idr: fix invalid ptr dereference on item delete If the radix tree underlying the IDR happens to be full and we attempt to remove an id which is larger than any id in the IDR, we will call __radix_tree_delete() with an uninitialised 'slot' pointer, at which point anything could happen. This was easiest to hit with a single entry at id 0 and attempting to remove a non-0 id, but it could have happened with 64 entries and attempting to remove an id >= 64. Roman said: The syzcaller test boils down to opening /dev/kvm, creating an eventfd, and calling a couple of KVM ioctls. None of this requires superuser. And the result is dereferencing an uninitialized pointer which is likely a crash. The specific path caught by syzbot is via KVM_HYPERV_EVENTD ioctl which is new in 4.17. But I guess there are other user-triggerable paths, so cc:stable is probably justified. Matthew added: We have around 250 calls to idr_remove() in the kernel today. Many of them pass an ID which is embedded in the object they're removing, so they're safe. Picking a few likely candidates: drivers/firewire/core-cdev.c looks unsafe; the ID comes from an ioctl. drivers/gpu/drm/amd/amdgpu/amdgpu_ctx.c is similar drivers/atm/nicstar.c could be taken down by a handcrafted packet Link: http://lkml.kernel.org/r/20180518175025.GD6361@bombadil.infradead.org Fixes: 0a835c4f090a ("Reimplement IDR and IDA using the radix tree") Reported-by: <syzbot+35666cba7f0a337e2e79(a)syzkaller.appspotmail.com> Debugged-by: Roman Kagan <rkagan(a)virtuozzo.com> Signed-off-by: Matthew Wilcox <mawilcox(a)microsoft.com> Cc: <stable(a)vger.kernel.org> Signed-off-by: Andrew Morton <akpm(a)linux-foundation.org> --- lib/radix-tree.c | 4 +++- tools/testing/radix-tree/idr-test.c | 7 +++++++ 2 files changed, 10 insertions(+), 1 deletion(-) diff -puN lib/radix-tree.c~idr-fix-invalid-ptr-dereference-on-item-delete lib/radix-tree.c --- a/lib/radix-tree.c~idr-fix-invalid-ptr-dereference-on-item-delete +++ a/lib/radix-tree.c @@ -2034,10 +2034,12 @@ void *radix_tree_delete_item(struct radi unsigned long index, void *item) { struct radix_tree_node *node = NULL; - void __rcu **slot; + void __rcu **slot = NULL; void *entry; entry = __radix_tree_lookup(root, index, &node, &slot); + if (!slot) + return NULL; if (!entry && (!is_idr(root) || node_tag_get(root, node, IDR_FREE, get_slot_offset(node, slot)))) return NULL; diff -puN tools/testing/radix-tree/idr-test.c~idr-fix-invalid-ptr-dereference-on-item-delete tools/testing/radix-tree/idr-test.c --- a/tools/testing/radix-tree/idr-test.c~idr-fix-invalid-ptr-dereference-on-item-delete +++ a/tools/testing/radix-tree/idr-test.c @@ -252,6 +252,13 @@ void idr_checks(void) idr_remove(&idr, 3); idr_remove(&idr, 0); + assert(idr_alloc(&idr, DUMMY_PTR, 0, 0, GFP_KERNEL) == 0); + idr_remove(&idr, 1); + for (i = 1; i < RADIX_TREE_MAP_SIZE; i++) + assert(idr_alloc(&idr, DUMMY_PTR, 0, 0, GFP_KERNEL) == i); + idr_remove(&idr, 1 << 30); + idr_destroy(&idr); + for (i = INT_MAX - 3UL; i < INT_MAX + 1UL; i++) { struct item *item = item_create(i, 0); assert(idr_alloc(&idr, item, i, i + 10, GFP_KERNEL) == i); _ Patches currently in -mm which might be from mawilcox(a)microsoft.com are slab-__gfp_zero-is-incompatible-with-a-constructor.patch s390-use-_refcount-for-pgtables.patch mm-split-page_type-out-from-_mapcount.patch mm-mark-pages-in-use-for-page-tables.patch mm-switch-s_mem-and-slab_cache-in-struct-page.patch mm-move-private-union-within-struct-page.patch mm-move-_refcount-out-of-struct-page-union.patch mm-combine-first-three-unions-in-struct-page.patch mm-use-page-deferred_list.patch mm-move-lru-union-within-struct-page.patch mm-combine-lru-and-main-union-in-struct-page.patch mm-improve-struct-page-documentation.patch mm-add-pt_mm-to-struct-page.patch mm-add-hmm_data-to-struct-page.patch slabslub-remove-rcu_head-size-checks.patch slub-remove-kmem_cache-reserved.patch slub-remove-reserved-file-from-sysfs.patch ida-remove-simple_ida_lock.patch

Re: [PATCH] Input: atmel_mxt_ts - add touchpad button mapping for Samsung Chromebook 3

There is quite a reshuffle going on between chromeos-laptop.c and atmel_mxt_ts at the moment, and your patch does not apply. I think the best way forward would be: - get this patch into stable train as is - I'll prepare a new patch that makes necessary changes in chromeos-laptop.c for the upcoming merge window. That means that 4.17 will not have the fix, but the first stable release of 4.17.x should have it.

[PATCH v3] rtc: sun6i: Fix bit_idx value for clk_register_gate

by Jagan Teki

From: Michael Trimarchi <michael(a)amarulasolutions.com> clk-gate core will take bit_idx through clk_register_gate and then do clk_gate_ops by using BIT(bit_idx), but rtc-sun6i is passing bit_idx as BIT(bit_idx) it becomes BIT(BIT(bit_idx) which is wrong and eventually external gate clock is not enabling. This patch fixed by passing bit index and the original change introduced from below commit.

[for-next][PATCH 13/19] ftrace/selftest: Have the reset_trigger code be a bit more careful

by Steven Rostedt

From: "Steven Rostedt (VMware)" <rostedt(a)goodmis.org> The trigger code is picky in how it can be disabled as there may be dependencies between different events and synthetic events. Change the order on how triggers are reset. 1) Reset triggers of all synthetic events first 2) Remove triggers with actions attached to them 3) Remove all other triggers If this order isn't followed, then some triggers will not be reset, and an error may happen because a trigger is busy.

[PATCH] mei: discard messages from not connected client during power down.

From: Alexander Usyskin <alexander.usyskin(a)intel.com> This fixes regression introduced by commit 8d52af6795c0 ("mei: speed up the power down flow") In power down or suspend flow a message can still be received from the FW because the clients fake disconnection. In normal case we interpret messages w/o destination as corrupted and link reset is performed in order to clean the channel, but during power down link reset is already in progress resulting in endless loop.

[PATCH 4.4] powerpc/64s: Clear PCR on boot

by Michael Neuling

Clear the PCR (Processor Compatibility Register) on boot to ensure we are not running in a compatibility mode. We've seen this cause problems when a crash (and kdump) occurs while running compat mode guests. The kdump kernel then runs with the PCR set and causes problems.

[PATCH v2] scsi_transport_srp: Fix shost to rport translation

by Bart Van Assche

Since an SRP remote port is attached as a child to shost->shost_gendev and as the only child, the translation from the shost pointer into an rport pointer must happen by looking up the shost child that is an rport. This patch fixes the following KASAN complaint: BUG: KASAN: slab-out-of-bounds in srp_timed_out+0x57/0x110 [scsi_transport_srp] Read of size 4 at addr ffff880035d3fcc0 by task kworker/1:0H/19 CPU: 1 PID: 19 Comm: kworker/1:0H Not tainted 4.16.0-rc3-dbg+ #1 Workqueue: kblockd blk_mq_timeout_work Call Trace: dump_stack+0x85/0xc7 print_address_description+0x65/0x270 kasan_report+0x231/0x350 srp_timed_out+0x57/0x110 [scsi_transport_srp] scsi_times_out+0xc7/0x3f0 [scsi_mod] blk_mq_terminate_expired+0xc2/0x140 bt_iter+0xbc/0xd0 blk_mq_queue_tag_busy_iter+0x1c7/0x350 blk_mq_timeout_work+0x325/0x3f0 process_one_work+0x441/0xa50 worker_thread+0x76/0x6c0 kthread+0x1b2/0x1d0 ret_from_fork+0x24/0x30 Fixes: e68ca75200fe ("scsi_transport_srp: Reduce failover time") Signed-off-by: Bart Van Assche <bart.vanassche(a)wdc.com> Cc: Hannes Reinecke <hare(a)suse.com> Cc: Johannes Thumshirn <jthumshirn(a)suse.de> Cc: Jason Gunthorpe <jgg(a)mellanox.com> Cc: Doug Ledford <dledford(a)redhat.com> Cc: Laurence Oberman <loberman(a)redhat.com> Cc: stable(a)vger.kernel.org --- Changes compared to v1: added a check in srp_timed_out() that checks whether or not rport != NULL. drivers/scsi/scsi_transport_srp.c | 22 ++++++++++++++++++++-- 1 file changed, 20 insertions(+), 2 deletions(-) diff --git a/drivers/scsi/scsi_transport_srp.c b/drivers/scsi/scsi_transport_srp.c index 36f6190931bc..456ce9f19569 100644 --- a/drivers/scsi/scsi_transport_srp.c +++ b/drivers/scsi/scsi_transport_srp.c @@ -51,6 +51,8 @@ struct srp_internal { struct transport_container rport_attr_cont; }; +static int scsi_is_srp_rport(const struct device *dev); + #define to_srp_internal(tmpl) container_of(tmpl, struct srp_internal, t) #define dev_to_rport(d) container_of(d, struct srp_rport, dev) @@ -60,9 +62,24 @@ static inline struct Scsi_Host *rport_to_shost(struct srp_rport *r) return dev_to_shost(r->dev.parent); } +static int find_child_rport(struct device *dev, void *data) +{ + struct device **child = data; + + if (scsi_is_srp_rport(dev)) { + WARN_ON_ONCE(*child); + *child = dev; + } + return 0; +} + static inline struct srp_rport *shost_to_rport(struct Scsi_Host *shost) { - return transport_class_to_srp_rport(&shost->shost_gendev); + struct device *child = NULL; + + WARN_ON_ONCE(device_for_each_child(&shost->shost_gendev, &child, + find_child_rport) < 0); + return child ? dev_to_rport(child) : NULL; } /** @@ -600,7 +617,8 @@ enum blk_eh_timer_return srp_timed_out(struct scsi_cmnd *scmd) struct srp_rport *rport = shost_to_rport(shost); pr_debug("timeout for sdev %s\n", dev_name(&sdev->sdev_gendev)); - return rport->fast_io_fail_tmo < 0 && rport->dev_loss_tmo < 0 && + return rport && rport->fast_io_fail_tmo < 0 && + rport->dev_loss_tmo < 0 && i->f->reset_timer_if_blocked && scsi_device_blocked(sdev) ?

[PATCH 1/3] ubi: fastmap: Correctly handle interrupted erasures in EBA

by Richard Weinberger

Fastmap cannot track the LEB unmap operation, therefore it can happen that after an interrupted erasure the mapping still looks good from Fastmap's point of view, while reading from the PEB will cause an ECC error and confuses the upper layer. Instead of teaching users of UBI how to deal with that, we read back the VID header and check for errors. If the PEB is empty or shows ECC errors we fixup the mapping and schedule the PEB for erasure.

[PATCH] KVM: irqfd: fix race between EPOLLHUP and irq_bypass_register_consumer

by Paolo Bonzini

A comment warning against this bug is there, but the code is not doing what the comment says. Therefore it is possible that an EPOLLHUP races against irq_bypass_register_consumer. The EPOLLHUP handler schedules irqfd_shutdown, and if that runs soon enough, you get a use-after-free.

[PATCH] mm, page_alloc: do not break __GFP_THISNODE by zonelist reset

by Vlastimil Babka

In __alloc_pages_slowpath() we reset zonelist and preferred_zoneref for allocations that can ignore memory policies. The zonelist is obtained from current CPU's node. This is a problem for __GFP_THISNODE allocations that want to allocate on a different node, e.g. because the allocating thread has been migrated to a different CPU. This has been observed to break SLAB in our 4.4-based kernel, because there it relies on __GFP_THISNODE working as intended. If a slab page is put on wrong node's list, then further list manipulations may corrupt the list because page_to_nid() is used to determine which node's list_lock should be locked and thus we may take a wrong lock and race. Current SLAB implementation seems to be immune by luck thanks to commit 511e3a058812 ("mm/slab: make cache_grow() handle the page allocated on arbitrary node") but there may be others assuming that __GFP_THISNODE works as promised. We can fix it by simply removing the zonelist reset completely. There is actually no reason to reset it, because memory policies and cpusets don't affect the zonelist choice in the first place. This was different when commit 183f6371aac2 ("mm: ignore mempolicies when using ALLOC_NO_WATERMARK") introduced the code, as mempolicies provided their own restricted zonelists. Signed-off-by: Vlastimil Babka <vbabka(a)suse.cz> Fixes: 183f6371aac2 ("mm: ignore mempolicies when using ALLOC_NO_WATERMARK") Cc: <stable(a)vger.kernel.org> --- Hi, we might consider this for 4.17 although I don't know if there's anything currently broken. Stable backports should be more important, but will have to be reviewed carefully, as the code went through many changes. BTW I think that also the ac->preferred_zoneref reset is currently useless if we don't also reset ac->nodemask from a mempolicy to NULL first (which we probably should for the OOM victims etc?), but I would leave that for a separate patch.

Re: Patch "drm/vmwgfx: Unpin the screen object backup buffer when not used" has been added to the 4.16-stable tree

by Thomas Hellstrom

Hi Greg, On 05/27/2018 04:32 PM, gregkh(a)linuxfoundation.org wrote: > This is a note to let you know that I've just added the patch titled > > drm/vmwgfx: Unpin the screen object backup buffer when not used > > to the 4.16-stable tree which can be found at: > https://urldefense.proofpoint.com/v2/url?u=http-3A__www.kernel.org_git_-3Fp… I got an identical message on May 2nd that this patch was added to the 4.16 and 4.14 stable trees. Now there is a small but important fix to this patch so I CC'd it to stable assuming that this patch was already in those versions. Fix is "drm/vmwgfx: Set dmabuf_size_when vmw_dmabuf_init is successful" by Deepak Rawat. It's correct to have both this patch and its fix in stable. Thanks, Thomas

[PATCH] ocfs2: fix a misuse a of brelse after failing ocfs2_check_dir_entry

by Changwei Ge

From: Changwei Ge <ge.changwei(a)h3c.com> Somehow, file system metadata was corrupted, which causes ocfs2_check_dir_entry() to fail in function ocfs2_dir_foreach_blk_el(). According to the original design intention, if above happens we should skip the problematic block and continue to retrieve dir entry. But there is obviouse misuse of brelse around related code. After failure of ocfs2_check_dir_entry(), currunt code just moves to next position and uses the problematic buffer head again and again during which the problematic buffer head is released for multiple times. I suppose, this a serious issue which is long-lived in ocfs2. This may cause other file systems which is also used in a the same host insane. So we should also consider about bakcporting this patch into linux -stable.

[PATCH 1/1] media: uvc_driver: fix USB Camera ref leak denial of service

by David Fries

Commit 9d15cd958c17 ("media: uvcvideo: Convert from using an atomic variable to a reference count") didn't take into account that while the old counter was initialized to 0 (no stream open), kref_init starts with a reference of 1. The reference count on unplug no longer reaches 0, uvc_delete isn't called, and evdev doesn't release /dev/input/event*. Plug and unplug enough times and it runs out of device minors preventing any new input device and the use of newly plugged in USB video cameras until the system is rebooted.

[PATCH 0/1] media: uvc_driver: fix USB Camera ref leak denial of service

by David Fries

The patch in the following e-mail fixes a reference count bug, it seems to me that uvc_unregister_video is a good location to release the final reference, I find it is called once. It may sound like a lot to plug and unplug the USB camera 250 some times, but in my case "disabled by hub (EMI?), re-enabling..." kept unplugging and plugging in the device until days later it ran out of minors and I lost the video security feed. With this patch, now that the device is actually being removed other problems are showing up. Specifically the following if the camera is removed or `rmmod ehci_pci` while an application is getting video from it. It doesn't happen if the camera is not in use. How do I track that down? sysfs group 'power' not found for kobject 'event10' sysfs group 'power' not found for kobject 'input32' sysfs group 'id' not found for kobject 'input32' sysfs group 'capabilities' not found for kobject 'input32' sysfs group 'power' not found for kobject 'media0' -- David Fries <david(a)fries.net>

Please apply this XFS patch on 4.4

by Daniel Sangorrin

Subject of the patch: xfs: remove racy hasattr check from attr ops Commit ID: 5a93790d4e2df73e30c965ec6e49be82fc3ccfce Why: It didn't pass LTP getxattr04 test, which is "a regression test for the race between getting an existing xattr and setting/removing a large xattr. This bug leads to that getxattr() fails to get an existing xattr and returns ENOATTR in xfs filesystem." LTP test getxattr04 was FAILing with this error message: tst_device.c:230: INFO: Using test device LTP_DEV='/dev/loop0' tst_mkfs.c:83: INFO: Formatting /dev/loop0 with xfs opts='' extra opts='' tst_test.c:982: INFO: Timeout per run is 0h 05m 00s getxattr04.c:72: FAIL: getxattr() failed to get an existing attribute After patching 4.4.y and running the test again (on x86_64) it PASSes: tst_device.c:230: INFO: Using test device LTP_DEV='/dev/loop0' tst_mkfs.c:83: INFO: Formatting /dev/loop0 with xfs opts='' extra opts='' tst_test.c:982: INFO: Timeout per run is 0h 05m 00s getxattr04.c:82: PASS: getxattr() succeeded to get an existing attribute What kernel version: 4.4.y (Note: 4.9.y already has it applied) Thanks, Daniel Sangorrin

[PATCH v3 07/16] mtd: rawnand: qcom: wait for desc completion in all BAM channels

by Abhishek Sahu

The BAM has 3 channels - tx, rx and command. command channel is used for register read/writes, tx channel for data writes and rx channel for data reads. Currently, the driver assumes the transfer completion once it gets all the command descriptors completed. Sometimes, there is race condition between data channel (tx/rx) and command channel completion. In these cases, the data present in buffer is not valid during small window between command descriptor completion and data descriptor completion. This patch generates NAND transfer completion when both (Data and Command) DMA channels have completed all its DMA descriptors. It assigns completion callback in last DMA descriptors of that channel and wait for completion.

[git:media_tree/master] media: vsp1: Release buffers for each video node

by Mauro Carvalho Chehab

This is an automatic generated email to let you know that the following patch were queued: Subject: media: vsp1: Release buffers for each video node Author: Kieran Bingham <kieran.bingham+renesas(a)ideasonboard.com> Date: Fri May 18 16:41:54 2018 -0400 Commit 372b2b0399fc ("media: v4l: vsp1: Release buffers in start_streaming error path") introduced a helper to clean up buffers on error paths, but inadvertently changed the code such that only the output WPF buffers were cleaned, rather than the video node being operated on. Since then vsp1_video_cleanup_pipeline() has grown to perform both video node cleanup, as well as pipeline cleanup. Split the implementation into two distinct functions that perform the required work, so that each video node can release its buffers correctly on streamoff. The pipe cleanup that was performed in the vsp1_video_stop_streaming() (releasing the pipe->dl) is moved to the function for clarity.

[patch 16/16] kasan: fix memory hotplug during boot

[patch 07/16] mm/kasan: don't vfree() nonexistent vm_area

by akpm＠linux-foundation.org

From: Andrey Ryabinin <aryabinin(a)virtuozzo.com> Subject: mm/kasan: don't vfree() nonexistent vm_area KASAN uses different routines to map shadow for hot added memory and memory obtained in boot process. Attempt to offline memory onlined by normal boot process leads to this: Trying to vfree() nonexistent vm area (000000005d3b34b9) WARNING: CPU: 2 PID: 13215 at mm/vmalloc.c:1525 __vunmap+0x147/0x190 Call Trace: kasan_mem_notifier+0xad/0xb9 notifier_call_chain+0x166/0x260 __blocking_notifier_call_chain+0xdb/0x140 __offline_pages+0x96a/0xb10 memory_subsys_offline+0x76/0xc0 device_offline+0xb8/0x120 store_mem_state+0xfa/0x120 kernfs_fop_write+0x1d5/0x320 __vfs_write+0xd4/0x530 vfs_write+0x105/0x340 SyS_write+0xb0/0x140 Obviously we can't call vfree() to free memory that wasn't allocated via vmalloc(). Use find_vm_area() to see if we can call vfree(). Unfortunately it's a bit tricky to properly unmap and free shadow allocated during boot, so we'll have to keep it. If memory will come online again that shadow will be reused. Matthew asked: how can you call vfree() on something that isn't a vmalloc address? vfree() is able to free any address returned by __vmalloc_node_range().

[patch 05/16] ipc/shm: fix shmat() nil address after round-down when remapping

by akpm＠linux-foundation.org

From: Davidlohr Bueso <dave(a)stgolabs.net> Subject: ipc/shm: fix shmat() nil address after round-down when remapping shmat()'s SHM_REMAP option forbids passing a nil address for; this is in fact the very first thing we check for.

[patch 04/16] Revert "ipc/shm: Fix shmat mmap nil-page protection"

by akpm＠linux-foundation.org

From: Davidlohr Bueso <dave(a)stgolabs.net> Subject: Revert "ipc/shm: Fix shmat mmap nil-page protection" Patch series "ipc/shm: shmat() fixes around nil-page". These patches fix two issues reported[1] a while back by Joe and Andrea around how shmat(2) behaves with nil-page. The first reverts a commit that it was incorrectly thought that mapping nil-page (address=0) was a no no with MAP_FIXED. This is not the case, with the exception of SHM_REMAP; which is address in the second patch. I chose two patches because it is easier to backport and it explicitly reverts bogus behaviour. Both patches ought to be in -stable and ltp testcases need updated (the added testcase around the cve can be modified to just test for SHM_RND|SHM_REMAP). [1] lkml.kernel.org/r/20180430172152.nfa564pvgpk3ut7p@linux-n805 This patch (of 2): 95e91b831f87 ("ipc/shm: Fix shmat mmap nil-page protection") worked on the idea that we should not be mapping as root addr=0 and MAP_FIXED. However, it was reported that this scenario is in fact valid, thus making the patch both bogus and breaks userspace as well. For example X11's libint10.so relies on shmat(1, SHM_RND) for lowmem initialization[1].

[patch 03/16] idr: fix invalid ptr dereference on item delete

by akpm＠linux-foundation.org

From: Matthew Wilcox <mawilcox(a)microsoft.com> Subject: idr: fix invalid ptr dereference on item delete If the radix tree underlying the IDR happens to be full and we attempt to remove an id which is larger than any id in the IDR, we will call __radix_tree_delete() with an uninitialised 'slot' pointer, at which point anything could happen. This was easiest to hit with a single entry at id 0 and attempting to remove a non-0 id, but it could have happened with 64 entries and attempting to remove an id >= 64. Roman said: The syzcaller test boils down to opening /dev/kvm, creating an eventfd, and calling a couple of KVM ioctls. None of this requires superuser. And the result is dereferencing an uninitialized pointer which is likely a crash. The specific path caught by syzbot is via KVM_HYPERV_EVENTD ioctl which is new in 4.17. But I guess there are other user-triggerable paths, so cc:stable is probably justified. Matthew added: We have around 250 calls to idr_remove() in the kernel today. Many of them pass an ID which is embedded in the object they're removing, so they're safe. Picking a few likely candidates: drivers/firewire/core-cdev.c looks unsafe; the ID comes from an ioctl. drivers/gpu/drm/amd/amdgpu/amdgpu_ctx.c is similar drivers/atm/nicstar.c could be taken down by a handcrafted packet Link: http://lkml.kernel.org/r/20180518175025.GD6361@bombadil.infradead.org Fixes: 0a835c4f090a ("Reimplement IDR and IDA using the radix tree") Reported-by: <syzbot+35666cba7f0a337e2e79(a)syzkaller.appspotmail.com> Debugged-by: Roman Kagan <rkagan(a)virtuozzo.com> Signed-off-by: Matthew Wilcox <mawilcox(a)microsoft.com> Cc: <stable(a)vger.kernel.org> Signed-off-by: Andrew Morton <akpm(a)linux-foundation.org> --- lib/radix-tree.c | 4 +++- tools/testing/radix-tree/idr-test.c | 7 +++++++ 2 files changed, 10 insertions(+), 1 deletion(-) diff -puN lib/radix-tree.c~idr-fix-invalid-ptr-dereference-on-item-delete lib/radix-tree.c --- a/lib/radix-tree.c~idr-fix-invalid-ptr-dereference-on-item-delete +++ a/lib/radix-tree.c @@ -2034,10 +2034,12 @@ void *radix_tree_delete_item(struct radi unsigned long index, void *item) { struct radix_tree_node *node = NULL; - void __rcu **slot; + void __rcu **slot = NULL; void *entry; entry = __radix_tree_lookup(root, index, &node, &slot); + if (!slot) + return NULL; if (!entry && (!is_idr(root) || node_tag_get(root, node, IDR_FREE, get_slot_offset(node, slot)))) return NULL; diff -puN tools/testing/radix-tree/idr-test.c~idr-fix-invalid-ptr-dereference-on-item-delete tools/testing/radix-tree/idr-test.c --- a/tools/testing/radix-tree/idr-test.c~idr-fix-invalid-ptr-dereference-on-item-delete +++ a/tools/testing/radix-tree/idr-test.c @@ -252,6 +252,13 @@ void idr_checks(void) idr_remove(&idr, 3); idr_remove(&idr, 0); + assert(idr_alloc(&idr, DUMMY_PTR, 0, 0, GFP_KERNEL) == 0); + idr_remove(&idr, 1); + for (i = 1; i < RADIX_TREE_MAP_SIZE; i++) + assert(idr_alloc(&idr, DUMMY_PTR, 0, 0, GFP_KERNEL) == i); + idr_remove(&idr, 1 << 30); + idr_destroy(&idr); + for (i = INT_MAX - 3UL; i < INT_MAX + 1UL; i++) { struct item *item = item_create(i, 0); assert(idr_alloc(&idr, item, i, i + 10, GFP_KERNEL) == i); _

The zonelist is obtained from current CPU's node. This is a problem for __GFP_THISNODE allocations that want to allocate on a different node, e.g. because the allocating thread has been migrated to a different CPU. This has been observed to break SLAB in our 4.4-based kernel, because there it relies on __GFP_THISNODE working as intended. If a slab page is put on wrong node's list, then further list manipulations may corrupt the list because page_to_nid() is used to determine which node's list_lock should be locked and thus we may take a wrong lock and race. Current SLAB implementation seems to be immune by luck thanks to commit 511e3a058812 ("mm/slab: make cache_grow() handle the page allocated on arbitrary node") but there may be others assuming that __GFP_THISNODE works as promised. We can fix it by simply removing the zonelist reset completely. There is actually no reason to reset it, because memory policies and cpusets don't affect the zonelist choice in the first place. This was different when commit 183f6371aac2 ("mm: ignore mempolicies when using ALLOC_NO_WATERMARK") introduced the code, as mempolicies provided their own restricted zonelists. We might consider this for 4.17 although I don't know if there's anything currently broken. Stable backports should be more important, but will have to be reviewed carefully, as the code went through many changes. BTW I think that also the ac->preferred_zoneref reset is currently useless if we don't also reset ac->nodemask from a mempolicy to NULL first (which we probably should for the OOM victims etc?), but I would leave that for a separate patch.

[PATCH v11 1/4] ioremap: Update pgtable free interfaces with addr

by Chintan Pandya

From: Chintan Pandya <cpandya(a)codeaurora.org> The following kernel panic was observed on ARM64 platform due to a stale TLB entry. 1. ioremap with 4K size, a valid pte page table is set. 2. iounmap it, its pte entry is set to 0. 3. ioremap the same address with 2M size, update its pmd entry with a new value. 4. CPU may hit an exception because the old pmd entry is still in TLB, which leads to a kernel panic. Commit b6bdb7517c3d ("mm/vmalloc: add interfaces to free unmapped page table") has addressed this panic by falling to pte mappings in the above case on ARM64. To support pmd mappings in all cases, TLB purge needs to be performed in this case on ARM64. Add a new arg, 'addr', to pud_free_pmd_page() and pmd_free_pte_page() so that TLB purge can be added later in seprate patches.

[PATCH] MIPS: lantiq: gphy: Drop reboot/remove reset asserts

by Mathias Kresin

While doing a global software reset, these bits are not cleared and let some bootloader fail to initialise the GPHYs. The bootloader don't expect the GPHYs in reset, as they aren't during power on. The asserts were a workaround for a wrong syscon-reboot mask. With a mask set which includes the GPHY resets, these resets aren't required any more.

[PATCH 00/11] mm: Teach memory_failure() about ZONE_DEVICE pages

by Dan Williams

As it stands, memory_failure() gets thoroughly confused by dev_pagemap backed mappings. The recovery code has specific enabling for several possible page states and needs new enabling to handle poison in dax mappings. In order to support reliable reverse mapping of user space addresses add new locking in the fsdax implementation to prevent races between page-address_space disassociation events and the rmap performed in the memory_failure() path. Additionally, since dev_pagemap pages are hidden from the page allocator, add a mechanism to determine the size of the mapping that encompasses a given poisoned pfn. Lastly, since pmem errors can be repaired, change the speculatively accessed poison protection, mce_unmap_kpfn(), to be reversible and otherwise allow ongoing access from the kernel. --- Dan Williams (11): device-dax: convert to vmf_insert_mixed and vm_fault_t device-dax: cleanup vm_fault de-reference chains device-dax: enable page_mapping() device-dax: set page->index filesystem-dax: set page->index filesystem-dax: perform __dax_invalidate_mapping_entry() under the page lock mm, madvise_inject_error: fix page count leak x86, memory_failure: introduce {set,clear}_mce_nospec() mm, memory_failure: pass page size to kill_proc() mm, memory_failure: teach memory_failure() about dev_pagemap pages libnvdimm, pmem: restore page attributes when clearing errors arch/x86/include/asm/set_memory.h | 29 ++++++ arch/x86/kernel/cpu/mcheck/mce-internal.h | 15 --- arch/x86/kernel/cpu/mcheck/mce.c | 38 +------- drivers/dax/device.c | 91 ++++++++++++-------- drivers/nvdimm/pmem.c | 26 ++++++ drivers/nvdimm/pmem.h | 13 +++ fs/dax.c | 102 ++++++++++++++++++++-- include/linux/huge_mm.h | 5 + include/linux/set_memory.h | 14 +++ mm/huge_memory.c | 4 - mm/madvise.c | 11 ++ mm/memory-failure.c | 133 +++++++++++++++++++++++++++-- 12 files changed, 370 insertions(+), 111 deletions(-)

[PATCH 3/3] x86/platform/UV: Add kernel parameter to set memory block size

by mike.travis＠hpe.com

Add a kernel parameter that allows setting UV memory block size. This is to provide an adjustment for new forms of PMEM and other DIMM memory that might require alignment restrictions other than scanning the global address table for the required minimum alignment. The value set will be further adjusted by both the GAM range table scan as well as restrictions imposed by set_memory_block_size_order().

[PATCH 2/3] x86/platform/UV: Use new set memory block size function

by mike.travis＠hpe.com

Add a call to the new function to "adjust" the current fixed UV memory block size of 2GB so it can be changed to a different physical boundary. This accommodates changes in the Intel BIOS, and therefore UV BIOS, which now can align boundaries different than the previous UV standard of 2GB. It also flags any UV Global Address boundaries from BIOS that cause a change in the mem block size (boundary). The current boundary of 2GB has been used on UV since the first system release in 2009 with Linux 2.6 and has worked fine. But the new NVDIMM persistent memory modules (PMEM), along with the Intel BIOS changes to support these modules caused the memory block size boundary to be set to a lower limit. Intel only guarantees that this minimum boundary at 64MB though the current Linux limit is 128MB. Note that the default remains 2GB if no changes occur.

[PATCH 1/3] x86/platform/UV: Add adjustable set memory block size function

by mike.travis＠hpe.com

Add a new function to "adjust" the current fixed UV memory block size of 2GB so it can be changed to a different physical boundary. This is out of necessity so arch dependent code can accommodate specific BIOS requirements which can align these new PMEM modules at less than the default boundaries. A "set order" type of function was used to insure that the memory block size will be a power of two value without requiring a validity check. 64GB was chosen as the upper limit for memory block size values to accommodate upcoming 4PB systems which have 6 more bits of physical address space (46 becoming 52).

[RESEND PATCH] ARM: dts: imx6q: Use correct SDMA script for SPI5 core

by Sean Nyekjaer

According to the reference manual the shp_2_mcu / mcu_2_shp scripts must be used for devices connected through the SPBA. This fixes an issue we saw with DMA transfers. Sometimes the SPI controller RX FIFO was not empty after a DMA transfer and the driver got stuck in the next PIO transfer when it read one word more than expected. commit dd4b487b32a35 ("ARM: dts: imx6: Use correct SDMA script for SPI cores") is fixing the same issue but only for SPI1 - 4. Fixes: 677940258dd8e ("ARM: dts: imx6q: enable dma for ecspi5") Signed-off-by: Sean Nyekjaer <sean.nyekjaer(a)prevas.dk> Reviewed-by: Fabio Estevam <fabio.estevam(a)nxp.com> --- arch/arm/boot/dts/imx6q.dtsi | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/arch/arm/boot/dts/imx6q.dtsi b/arch/arm/boot/dts/imx6q.dtsi index ae7b3f107893..5185300cc11f 100644 --- a/arch/arm/boot/dts/imx6q.dtsi +++ b/arch/arm/boot/dts/imx6q.dtsi @@ -96,7 +96,7 @@ clocks = <&clks IMX6Q_CLK_ECSPI5>, <&clks IMX6Q_CLK_ECSPI5>; clock-names = "ipg", "per"; - dmas = <&sdma 11 7 1>, <&sdma 12 7 2>; + dmas = <&sdma 11 8 1>, <&sdma 12 8 2>; dma-names = "rx", "tx"; status = "disabled"; }; -- 2.17.0

patch "usb-storage: Add compatibility quirk flags for G-Technologies G-Drive" added to usb-next

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled usb-storage: Add compatibility quirk flags for G-Technologies G-Drive to my usb git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git in the usb-next branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will also be merged in the next major kernel release during the merge window. If you have any questions about this process, please let me know. >From ca7d9515d0e6825351ce106066cea1f60e40b1c8 Mon Sep 17 00:00:00 2001 From: Alexander Kappner <agk(a)godking.net> Date: Fri, 18 May 2018 21:50:16 -0700 Subject: usb-storage: Add compatibility quirk flags for G-Technologies G-Drive The "G-Drive" (sold by G-Technology) external USB 3.0 drive hangs on write access under UAS and usb-storage: [ 136.079121] sd 15:0:0:0: [sdi] tag#0 FAILED Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE [ 136.079144] sd 15:0:0:0: [sdi] tag#0 Sense Key : Illegal Request [current] [ 136.079152] sd 15:0:0:0: [sdi] tag#0 Add.

The proposed patch adds compatibility quirks. Because the drive requires two quirks (one to work with UAS, and another to work with usb-storage), adding this under unusual_devs.h and not just unusual_uas.h so kernels compiled without UAS receive the quirk. With the patch, the drive works reliably on UAS and usb- storage. (tested on NEC Corporation uPD720200 USB 3.0 host controller).

Then, printer_write() calls list_add(&req->list, &dev->tx_reqs_active) wrongly.

[PATCH v2] block: fix QEMU crash with scsi-hd and drive_del

by Greg Kurz

Removing a drive with drive_del while it is being used to run an I/O intensive workload can cause QEMU to crash. An AIO flush can yield at some point: blk_aio_flush_entry() blk_co_flush(blk) bdrv_co_flush(blk->root->bs) ... qemu_coroutine_yield() and let the HMP command to run, free blk->root and give control back to the AIO flush: hmp_drive_del() blk_remove_bs() bdrv_root_unref_child(blk->root) child_bs = blk->root->bs bdrv_detach_child(blk->root) bdrv_replace_child(blk->root, NULL) blk->root->bs = NULL g_free(blk->root) <============== blk->root becomes stale bdrv_unref(child_bs) bdrv_delete(child_bs) bdrv_close() bdrv_drained_begin() bdrv_do_drained_begin() bdrv_drain_recurse() aio_poll() ... qemu_coroutine_switch() and the AIO flush completion ends up dereferencing blk->root: blk_aio_complete() scsi_aio_complete() blk_get_aio_context(blk) bs = blk_bs(blk) ie, bs = blk->root ? blk->root->bs : NULL ^^^^^ stale The problem is that we should avoid making block driver graph changes while we have in-flight requests. This patch hence adds a drained section to bdrv_detach_child(), so that we're sure all requests have been drained when blk->root is freed.

patch "usb-storage: Add compatibility quirk flags for G-Technologies G-Drive" added to usb-testing

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled usb-storage: Add compatibility quirk flags for G-Technologies G-Drive to my usb git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git in the usb-testing branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will be merged to the usb-next branch sometime soon, after it passes testing, and the merge window is open.

The proposed patch adds compatibility quirks. Because the drive requires two quirks (one to work with UAS, and another to work with usb-storage), adding this under unusual_devs.h and not just unusual_uas.h so kernels compiled without UAS receive the quirk.

Then, printer_write() calls list_add(&req->list, &dev->tx_reqs_active) wrongly. After that, if we do unbind the printer driver, WARN_ON() happens in printer_func_unbind() because the list entry is not removed.

[PATCH 3/6] drm/psr: Fix missed entry in PSR setup time table.

by Dhinakaran Pandiyan

Entry corresponding to 220 us setup time was missing. I am not aware of any specific bug this fixes, but this could potentially result in enabling PSR on a panel with a higher setup time requirement than supported by the hardware.

[PATCH v10 1/4] ioremap: Update pgtable free interfaces with addr

by Chintan Pandya

From: Chintan Pandya <cpandya(a)codeaurora.org> The following kernel panic was observed on ARM64 platform due to a stale TLB entry. 1. ioremap with 4K size, a valid pte page table is set. 2. iounmap it, its pte entry is set to 0. 3. ioremap the same address with 2M size, update its pmd entry with a new value. 4. CPU may hit an exception because the old pmd entry is still in TLB, which leads to a kernel panic. Commit b6bdb7517c3d ("mm/vmalloc: add interfaces to free unmapped page table") has addressed this panic by falling to pte mappings in the above case on ARM64. To support pmd mappings in all cases, TLB purge needs to be performed in this case on ARM64. Add a new arg, 'addr', to pud_free_pmd_page() and pmd_free_pte_page() so that TLB purge can be added later in seprate patches.

We work with the CIP kernel (v4.4), and from time to time we come across bug fixes we feel like stable could benefit from. Also, since Ben merges the CIP branch with stable, the fixes we make to stable will appear in the CIP kernel too at some point. If you feel like the patch is not worth considering for stable, it can still be applied to the CIP kernel if required. Ben has already taken this patch (for v4.4.126-cip22) therefore it's not on our critical path, but it would be nice to have in the stable kernel too. > What bug does it solve?

[PATCH] usb: typec: wcove: Remove dependency on HW FSM

by Heikki Krogerus

The USB Type-C PHY in Intel WhiskeyCove PMIC has build-in USB Type-C state machine which we were relying on to configure the CC lines correctly. This patch removes that dependency and configures the CC line according to commands from the port manager (tcpm.c) in wcove_set_cc(). This fixes an issue where USB devices attached to the USB Type-C port do not get enumerated. When acting as source/host, the HW FSM sometimes fails to configure the PHY correctly.
