[PATCH 02/27] blk-stat: make q->stats->lock irqsafe

by Tejun Heo

blk-iocost calls blk_stat_enable_accounting() while holding an irqsafe lock which triggers a lockdep splat because q->stats->lock isn't irqsafe. Let's make it irqsafe.

[PATCH 01/27] blk-iocost: ioc_pd_free() shouldn't assume irq disabled

by Tejun Heo

ioc_pd_free() grabs irq-safe ioc->lock without ensuring that irq is disabled when it can be called with irq disabled or enabled. This has a small chance of causing A-A deadlocks and triggers lockdep splats. Use irqsave operations instead.

[PATCH] drm/tve200: Stabilize enable/disable

by Linus Walleij

The TVE200 will occasionally print a bunch of lost interrupts and similar dmesg messages, sometimes during boot and sometimes after disabling and coming back to enablement. This is probably because the hardware is left in an unknown state by the boot loader that displays a logo. This can be fixed by bringing the controller into a known state by resetting the controller while enabling it. We retry reset 5 times like the vendor driver does. We also put the controller into reset before de-clocking it and clear all interrupts before enabling the vblank IRQ. This makes the video enable/disable/enable cycle rock solid on the D-Link DIR-685. Tested extensively.

[PATCH v2 4.19 0/7] Fix timeout clock used by hardware data timeout

by Sowjanya Komatineni

Tegra210/Tegra186/Tegra194 has incorrectly enabled SDHCI_QUIRK_DATA_TIMEOUT_USES_SDCLK from the beginning of their support. Tegra210 and later SDMMC hardware default uses sdmmc_legacy_tm (TMCLK) all the time for hardware data timeout instead of SDCLK and this TMCLK need to be kept enabled by Tegra sdmmc driver. This series includes manual backport patches to fix this for stable kernel #4.19 Note: Patch series v2 is same as v1 except updated commit message in all patches properly for backporting. Sowjanya Komatineni (7): sdhci: tegra: Remove SDHCI_QUIRK_DATA_TIMEOUT_USES_SDCLK for Tegra210 sdhci: tegra: Remove SDHCI_QUIRK_DATA_TIMEOUT_USES_SDCLK for Tegra186 dt-bindings: mmc: tegra: Add tmclk for Tegra210 and Tegra186 arm64: tegra: Add missing timeout clock to Tegra210 SDMMC arm64: tegra: Add missing timeout clock to Tegra186 SDMMC nodes arm64: tegra: Add missing timeout clock to Tegra194 SDMMC nodes sdhci: tegra: Add missing TMCLK for data timeout .../bindings/mmc/nvidia,tegra20-sdhci.txt | 23 +++++++++- arch/arm64/boot/dts/nvidia/tegra186.dtsi | 20 +++++---- arch/arm64/boot/dts/nvidia/tegra194.dtsi | 15 ++++--- arch/arm64/boot/dts/nvidia/tegra210.dtsi | 28 ++++++------ drivers/mmc/host/sdhci-tegra.c | 50 +++++++++++++++++++++- 5 files changed, 106 insertions(+), 30 deletions(-) -- 2.7.4

I hope the "Fixes" tag will work, but yeah, my bad, cc:stable is definitely a good idea here. Added stable@ to cc. Thanks!

[PATCH stable v5.4 0/3] KVM: arm64: Fix AT instruction handling

by Andre Przywara

In some architectural corner cases, AT instructions can generate an exception, which KVM is not really ready to handle properly. Teach the code to handle this situation gracefully. This is a backport of the respective upstream patches to v5.4(.61). James prepared these already, but we were lacking the upstream commit ID. I am sending this on his behalf, since he is off this week. The last two of the patches were tagged Cc: stable already, but did not apply cleanly, hence this specific backport. Cheers, Andre.

[PATCH] gfs2: Make sure we don't miss any delayed withdraws

by Andreas Gruenbacher

Commit ca399c96e96e changes gfs2_log_flush to not withdraw the filesystem while holding the log flush lock, but it fails to check if the filesystem needs to be withdrawn once the log flush lock has been released. Likewise, commit f05b86db314d depends on gfs2_log_flush to trigger for delayed withdraws. Add that and clean up the code flow somewhat.

[PATCH v5.4 0/6] Build time improvements

by Matthias Maennich

Hi, please pick up the following patches for 5.4. Those are build time optimizations for kernel/gen_kheaders.sh, and - by removing bashisms - dropping the dependency to /bin/bash. In addition, this enables build time improvements across the tree by optionally allowing to use alternative implementations for various compression tools, e.g. GZIP=pigz. The documentation-only change is not strictly necessary, but keeps kernel/gen_kheaders.sh in sync with mainline.

[PATCH 4.19 0/7] Fix timeout clock used by hardware data timeout

Tegra210/Tegra186/Tegra194 has incorrectly enabled SDHCI_QUIRK_DATA_TIMEOUT_USES_SDCLK from the beginning of their support.

[PATCH 07/11] evm: Set IMA_CHANGE_XATTR/ATTR bit if EVM_ALLOW_METADATA_WRITES is set

by Roberto Sassu

When EVM_ALLOW_METADATA_WRITES is set, EVM allows any operation on metadata. Its main purpose is to allow users to freely set metadata when they are protected by a portable signature, until the HMAC key is loaded. However, IMA is not notified about metadata changes and, after the first appraisal, always allows access to the files without checking metadata again. This patch checks in evm_reset_status() if EVM_ALLOW_METADATA WRITES is enabled and if it is, sets the IMA_CHANGE_XATTR/ATTR bits depending on the operation performed. At the next appraisal, metadata are revalidated. This patch also adds a call to evm_reset_status() in evm_inode_post_setattr() so that EVM won't return the cached status the next time appraisal is performed.

[PATCH v6 06/29] vmlinux.lds.h: add PGO and AutoFDO input sections

by Kees Cook

From: Nick Desaulniers <ndesaulniers(a)google.com> Basically, consider .text.{hot|unlikely|unknown}.* part of .text, too. When compiling with profiling information (collected via PGO instrumentations or AutoFDO sampling), Clang will separate code into .text.hot, .text.unlikely, or .text.unknown sections based on profiling information. After D79600 (clang-11), these sections will have a trailing `.` suffix, ie. .text.hot., .text.unlikely., .text.unknown.. When using -ffunction-sections together with profiling infomation, either explicitly (FGKASLR) or implicitly (LTO), code may be placed in sections following the convention: .text.hot.<foo>, .text.unlikely.<bar>, .text.unknown.<baz> where <foo>, <bar>, and <baz> are functions. (This produces one section per function; we generally try to merge these all back via linker script so that we don't have 50k sections). For the above cases, we need to teach our linker scripts that such sections might exist and that we'd explicitly like them grouped together, otherwise we can wind up with code outside of the _stext/_etext boundaries that might not be mapped properly for some architectures, resulting in boot failures. If the linker script is not told about possible input sections, then where the section is placed as output is a heuristic-laiden mess that's non-portable between linkers (ie. BFD and LLD), and has resulted in many hard to debug bugs. Kees Cook is working on cleaning this up by adding --orphan-handling=warn linker flag used in ARCH=powerpc to additional architectures. In the case of linker scripts, borrowing from the Zen of Python: explicit is better than implicit. Also, ld.bfd's internal linker script considers .text.hot AND .text.hot.* to be part of .text, as well as .text.unlikely and .text.unlikely.*. I didn't see support for .text.unknown.*, and didn't see Clang producing such code in our kernel builds, but I see code in LLVM that can produce such section names if profiling information is missing. That may point to a larger issue with generating or collecting profiles, but I would much rather be safe and explicit than have to debug yet another issue related to orphan section placement.

[PATCH stable v5.8 0/2] KVM: arm64: Fix AT instruction handling

by Andre Przywara

In some architectural corner cases, AT instructions can generate an exception, which KVM is not really ready to handle properly. Teach the code to handle this situation gracefully. This is a backport of the respective upstream patches to v5.8(.5). James prepared and tested these already, but we were lacking the upstream commit ID so far. I am sending this on his behalf, since he is off this week. The last two of the originally three patches were tagged Cc: stable already, but 2/3 did not apply cleanly, hence this specific backport. 3/3 has already been added to stable-queue, so I am dropping it from this post.

[PATCH v4] HID: core: Sanitize event code and type when mapping input

by Marc Zyngier

When calling into hid_map_usage(), the passed event code is blindly stored as is, even if it doesn't fit in the associated bitmap.

[PATCH] HID: core: Correctly handle ReportSize being zero

by Marc Zyngier

It appears that a ReportSize value of zero is legal, even if a bit non-sensical. Most of the HID code seems to handle that gracefully, except when computing the total size in bytes. When fed as input to memset, this leads to some funky outcomes. Detect the corner case and correctly compute the size.

[PATCH v2] usb: Fix out of sync data toggle if a configured device is reconfigured

by Mathias Nyman

Userspace drivers that use a SetConfiguration() request to "lightweight" reset an already configured usb device might cause data toggles to get out of sync between the device and host, and the device becomes unusable. The xHCI host requires endpoints to be dropped and added back to reset the toggle. If USB core notices the new configuration is the same as the current active configuration it will avoid these extra steps by calling usb_reset_configuration() instead of usb_set_configuration(). A SetConfiguration() request will reset the device side data toggles. Make sure usb_reset_configuration() function also drops and adds back the endpoints to ensure data toggles are in sync. To avoid code duplication split the current usb_disable_device() function and reuse the endpoint specific part.

[PATCH 1/2] i2c: i801: Fix runtime PM

by Jarkko Nikula

Commit 9c8088c7988 ("i2c: i801: Don't restore config registers on runtime PM") nullified the runtime PM suspend/resume callback pointers while keeping the runtime PM enabled. This causes that device stays in D0 power state and sysfs /sys/bus/pci/devices/.../power/runtime_status shows "error" when runtime PM framework attempts to autosuspend the device. This is due PCI bus runtime PM which checks for driver runtime PM callbacks and returns with -ENOSYS if they are not set. Fix this by having a shared dummy runtime PM callback that returns with success.

[PATCH] ARM: socfpga: arria10: fix timer3 address

by Steffen Trumtrar

Since commit 6d2e16a3181b ("clocksource: dw_apb_timer_of: Fix missing clockevent timers") the dw_apb_timer_of code tries to add a clockevent for timer3. This reveals the wrong register offset that is provided in the timer3-node in the socfpga_arria10 devicetree which in turn results in Unhandled fault: imprecise external abort (0x406) at 0xbea9fe20 and therefore in a kernel panic. Set the offset to the correct value.

[PATCH for-4.19] tpm: Unify the mismatching TPM space buffer sizes

by Stefan Berger

From: Jarkko Sakkinen <jarkko.sakkinen(a)linux.intel.com> The size of the buffers for storing context's and sessions can vary from arch to arch as PAGE_SIZE can be anything between 4 kB and 256 kB (the maximum for PPC64). Define a fixed buffer size set to 16 kB. This should be enough for most use with three handles (that is how many we allow at the moment). Parametrize the buffer size while doing this, so that it is easier to revisit this later on if required.

We can detect the signalfd case pretty easily by comparing the poll->head wait_queue_head_t with the target task signalfd wait queue. Just use normal task wakeup for this case.

[alternative-merged] fat-avoid-oops-when-bdi-io_pages==0.patch removed from -mm tree

by akpm＠linux-foundation.org

The patch titled Subject: fat: avoid oops when bdi->io_pages==0 has been removed from the -mm tree. Its filename was fat-avoid-oops-when-bdi-io_pages==0.patch This patch was dropped because an alternative patch was merged ------------------------------------------------------ From: OGAWA Hirofumi <hirofumi(a)mail.parknet.co.jp> Subject: fat: avoid oops when bdi->io_pages==0 On one system, there was bdi->io_pages==0. This seems to be the bug of a driver somewhere, which perhaps failed to initialize io_pages. We should fix it though - it is better to avoid the divide-by-zero Oops. So add a check for this.

[PATCH AUTOSEL 4.4 1/5] HID: hiddev: Fix slab-out-of-bounds write in hiddev_ioctl_usage()

by Sasha Levin

This currently causes io_uring to return -EINVAL if that is attempted, but we should allow that as documented.

MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit One of a class of bugs pointed out by Lars in a recent review. iio_push_to_buffers_with_timestamp assumes the buffer used is aligned to the size of the timestamp (8 bytes). This is not guaranteed in this driver which uses a 32 byte array of smaller elements on the stack. As Lars also noted this anti pattern can involve a leak of data to userspace and that indeed can happen here. We close both issues by moving to a suitable structure in the iio_priv() data with alignment explicitly requested. This data is allocated with kzalloc so no data can leak apart from previous readings.

This is a note to let you know that I've just added the patch titled iio:adc:ti-adc084s021 Fix alignment and data leak issues. to my staging git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git in the staging-linus 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.)

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 71a7f8cb1ca4ca7214a700b1243626759b6c11d4 Mon Sep 17 00:00:00 2001 From: James Morse <james.morse(a)arm.com> Date: Fri, 21 Aug 2020 15:07:07 +0100 Subject: [PATCH] KVM: arm64: Set HCR_EL2.PTW to prevent AT taking synchronous exception AT instructions do a translation table walk and return the result, or the fault in PAR_EL1. KVM uses these to find the IPA when the value is not provided by the CPU in HPFAR_EL1. If a translation table walk causes an external abort it is taken as an exception, even if it was due to an AT instruction. (DDI0487F.a's D5.2.11 "Synchronous faults generated by address translation instructions") While we previously made KVM resilient to exceptions taken due to AT instructions, the device access causes mismatched attributes, and may occur speculatively. Prevent this, by forbidding a walk through memory described as device at stage2. Now such AT instructions will report a stage2 fault. Such a fault will cause KVM to restart the guest.

AT instructions access the guest page tables, and can cause a synchronous external abort to be taken. The arm-arm is unclear on what should happen if the guest has configured the hardware update of the access-flag, and a memory type in TCR_EL1 that does not support atomic operations. B2.2.6 "Possible implementation restrictions on using atomic instructions" from DDI0487F.a lists synchronous external abort as a possible behaviour of atomic instructions that target memory that isn't writeback cacheable, but the page table walker may behave differently. Make KVM robust to synchronous exceptions caused by AT instructions. Add a get_user() style helper for AT instructions that returns -EFAULT if an exception was generated. While KVM's version of the exception table mixes synchronous and asynchronous exceptions, only one of these can occur at each location. Re-enter the guest when the AT instructions take an exception on the assumption the guest will take the same exception. This isn't guaranteed to make forward progress, as the AT instructions may always walk the page tables, but guest execution may use the translation cached in the TLB.

[PATCH] USB: serial: option: support dynamic Quectel USB compositions

by Bjørn Mork

The USB composition, defining the set of exported functions, is dynamic in newer Quectel modems. Default functions can be disabled and alternative functions can be enabled instead. The alternatives includes class functions using interface pairs, which should be handled by the respective class drivers. Active interfaces are numbered consecutively, so static blacklisting based on interface numbers will fail when the composition changes. An example of such an error, where the option driver has bound to the CDC ECM data interface, preventing cdc_ether from handling this function: T: Bus=01 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#= 2 Spd=480 MxCh= 0 D: Ver= 2.00 Cls=ef(misc ) Sub=02 Prot=01 MxPS=64 #Cfgs= 1 P: Vendor=2c7c ProdID=0125 Rev= 3.18 S: Manufacturer=Quectel S: Product=EC25-AF C:* #Ifs= 6 Cfg#= 1 Atr=a0 MxPwr=500mA A: FirstIf#= 4 IfCount= 2 Cls=02(comm.)

Here's a set of independent fixes against 5.9-rc2: prompted by testing Alex Shi's "warning on !memcg" and lru_lock series, but I think fit for 5.9 - though maybe only the first for stable. This patch (of 5): In 5.8 some instances of memcg charging in do_swap_page() and unuse_pte() were removed, on the understanding that swap cache is now already charged at those points; but a case was missed, when ksm_might_need_to_copy() has decided it must allocate a substitute page: such pages were never charged. Fix it inside ksm_might_need_to_copy(). This was discovered by Alex Shi's prospective commit "mm/memcg: warning on !memcg after readahead page charged". But there is a another surprise: this also fixes some rarer uncharged PageAnon cases, when KSM is configured in, but has never been activated. ksm_might_need_to_copy()'s anon_vma->root and linear_page_index() check sometimes catches a case which would need to have been copied if KSM were turned on. Or that's my optimistic interpretation (of my own old code), but it leaves some doubt as to whether everything is working as intended there - might it hint at rare anon ptes which rmap cannot find? A question not easily answered: put in the fix for missed memcg charges.

From: Tobias Schramm <t.schramm(a)manjaro.org> [ Upstream commit ae1ba50f1e706dfd7ce402ac52c1f1f10becad68 ] Previously the stm32h7 interrupt thread cleared all non-masked interrupts.

[tip: x86/urgent] genirq/matrix: Deal with the sillyness of for_each_cpu() on UP

This is historical, inconsistent and annoying behaviour. The matrix allocator uses for_each_cpu() and can be called on UP with an empty cpumask. The calling code does not expect that this succeeds but until commit e027fffff799 ("x86/irq: Unbreak interrupt affinity setting") this went unnoticed. That commit added a WARN_ON() to catch cases which move an interrupt from one vector to another on the same CPU. The warning triggers on UP. Add a check for the cpumask being empty to prevent this.

[PATCH 01/39] drm/i915/gem: Avoid implicit vmap for highmem on x86-32

by Chris Wilson

On 32b, highmem uses a finite set of indirect PTE (i.e. vmap) to provide virtual mappings of the high pages. As these are finite, map_new_virtual() must wait for some other kmap() to finish when it runs out. If we map a large number of objects, there is no method for it to tell us to release the mappings, and we deadlock. However, if we make an explicit vmap of the page, that uses a larger vmalloc arena, and also has the ability to tell us to release unwanted mappings. Most importantly, it will fail and propagate an error instead of waiting forever.

[PATCH] nvme: Revert: Fix controller creation races with teardown flow

by James Smart

The indicated patch introduced a barrier in the sysfs_delete attribute for the controller that rejects the request if the controller isn't created. "Created" is defined as at least 1 call to nvme_start_ctrl(). This is problematic in error-injection testing. If an error occurs on the initial attempt to create an association and the controller enters reconnect(s) attempts, the admin cannot delete the controller until either there is a successful association created or ctrl_loss_tmo times out. Where this issue is particularly hurtful is when the "admin" is the nvme-cli, it is performing a connection to a discovery controller, and it is initiated via auto-connect scripts. With the FC transport, if the first connection attempt fails, the controller enters a normal reconnect state but returns control to the cli thread that created the controller. In this scenario, the cli attempts to read the discovery log via ioctl, which fails, causing the cli to see it as an empty log and then proceeds to delete the discovery controller. The delete is rejected and the controller is left live. If the discovery controller reconnect then succeeds, there is no action to delete it, and it sits live doing nothing.
