[PATCH v4 1/3] mm/slab: Use memzero_explicit() in kzfree()

by Waiman Long

The kzfree() function is normally used to clear some sensitive information, like encryption keys, in the buffer before freeing it back to the pool. Memset() is currently used for the buffer clearing. However, it is entirely possible that the compiler may choose to optimize away the memory clearing especially if LTO is being used. To make sure that this optimization will not happen, memzero_explicit(), which is introduced in v3.18, is now used in kzfree() to do the clearing.

[PATCH v5 1/2] mm/slab: Use memzero_explicit() in kzfree()

by Waiman Long

The kzfree() function is normally used to clear some sensitive information, like encryption keys, in the buffer before freeing it back to the pool. Memset() is currently used for buffer clearing. However unlikely, there is still a non-zero probability that the compiler may choose to optimize away the memory clearing especially if LTO is being used in the future. To make sure that this optimization will never happen, memzero_explicit(), which is introduced in v3.18, is now used in kzfree() to future-proof it.

[PATCH stable-5.6] KVM: arm64: Save the host's PtrAuth keys in non-preemptible context

by Marc Zyngier

commit ef3e40a7ea8dbe2abd0a345032cd7d5023b9684f upstream When using the PtrAuth feature in a guest, we need to save the host's keys before allowing the guest to program them. For that, we dump them in a per-CPU data structure (the so called host context). But both call sites that do this are in preemptible context, which may end up in disaster should the vcpu thread get preempted before reentering the guest. Instead, save the keys eagerly on each vcpu_load(). This has an increased overhead, but is at least safe.

[PATCH] HID: quirks: Always poll Obins Anne Pro 2 keyboard

by Sebastian Parschauer

The Obins Anne Pro 2 keyboard (04d9:a293) disconnects after a few minutes of inactivity when using it wired and typing does not result in any input events any more. This is a common firmware flaw. So add the ALWAYS_POLL quirk for this device. GitHub user Dietrich Moerman (dietrichm) tested the quirk and requested my help in my project https://github.com/sriemer/fix-linux-mouse issue 22 to provide this patch.

[PATCH stable-4.19] KVM: arm64: Synchronize sysreg state on injecting an AArch32 exception

by Marc Zyngier

commit 0370964dd3ff7d3d406f292cb443a927952cbd05 upstream On a VHE system, the EL1 state is left in the CPU most of the time, and only syncronized back to memory when vcpu_put() is called (most of the time on preemption). Which means that when injecting an exception, we'd better have a way to either: (1) write directly to the EL1 sysregs (2) synchronize the state back to memory, and do the changes there For an AArch64, we already do (1), so we are safe. Unfortunately, doing the same thing for AArch32 would be pretty invasive. Instead, we can easily implement (2) by calling the put/load architectural backends, and keep preemption disabled. We can then reload the state back into EL1.

[PATCH stable-5.6] KVM: arm64: Synchronize sysreg state on injecting an AArch32 exception

by Marc Zyngier

commit 0370964dd3ff7d3d406f292cb443a927952cbd05 upstream On a VHE system, the EL1 state is left in the CPU most of the time, and only syncronized back to memory when vcpu_put() is called (most of the time on preemption). Which means that when injecting an exception, we'd better have a way to either: (1) write directly to the EL1 sysregs (2) synchronize the state back to memory, and do the changes there For an AArch64, we already do (1), so we are safe. Unfortunately, doing the same thing for AArch32 would be pretty invasive. Instead, we can easily implement (2) by calling the put/load architectural backends, and keep preemption disabled. We can then reload the state back into EL1.

[PATCH stable-5.4] KVM: arm64: Save the host's PtrAuth keys in non-preemptible context

by Marc Zyngier

commit ef3e40a7ea8dbe2abd0a345032cd7d5023b9684f upstream When using the PtrAuth feature in a guest, we need to save the host's keys before allowing the guest to program them. For that, we dump them in a per-CPU data structure (the so called host context). But both call sites that do this are in preemptible context, which may end up in disaster should the vcpu thread get preempted before reentering the guest. Instead, save the keys eagerly on each vcpu_load(). This has an increased overhead, but is at least safe.

[PATCH stable-5.7] KVM: arm64: Save the host's PtrAuth keys in non-preemptible context

by Marc Zyngier

commit ef3e40a7ea8dbe2abd0a345032cd7d5023b9684f upstream When using the PtrAuth feature in a guest, we need to save the host's keys before allowing the guest to program them. For that, we dump them in a per-CPU data structure (the so called host context). But both call sites that do this are in preemptible context, which may end up in disaster should the vcpu thread get preempted before reentering the guest. Instead, save the keys eagerly on each vcpu_load(). This has an increased overhead, but is at least safe.

sony-laptop fix for 5.6 and 5.7

by Mattia Dongili

commit 95e2c5b0fd6d7a022f37e7c762ea093aba7b8e34 upstream platform/x86: sony-laptop: SNC calls should handle BUFFER types After commit 6d232b29cfce ("ACPICA: Dispatcher: always generate buffer objects for ASL create_field() operator") ACPICA creates buffers even when new fields are small enough to fit into an integer. Many SNC calls counted on the old behaviour. Since sony-laptop already handles the INTEGER/BUFFER case in sony_nc_buffer_call, switch sony_nc_int_call to use its more generic function instead. Fixes: 6d232b29cfce ("ACPICA: Dispatcher: always generate buffer objects for ASL create_field() operator") Reported-by: Dominik Mierzejewski <dominik(a)greysector.net> Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=207491 Reported-by: William Bader <williambader(a)hotmail.com> Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1830150 Signed-off-by: Mattia Dongili <malattia(a)linux.it> --- ACPICA broke resume from s2ram for some Vaio laptops in 5.6. The platform drivers maintainers didn't send the fix for 5.7, so the commit is needed both on 5.6 and on 5.7. Thanks -- mattia :wq!

[PATCH v1 1/3] mm/shuffle: don't move pages between zones and don't read garbage memmaps

by David Hildenbrand

Especially with memory hotplug, we can have offline sections (with a garbage memmap) and overlapping zones. We have to make sure to only touch initialized memmaps (online sections managed by the buddy) and that the zone matches, to not move pages between zones. To test if this can actually happen, I added a simple BUG_ON(page_zone(page_i) != page_zone(page_j)); right before the swap. When hotplugging a 256M DIMM to a 4G x86-64 VM and onlining the first memory block "online_movable" and the second memory block "online_kernel", it will trigger the BUG, as both zones (NORMAL and MOVABLE) overlap. This might result in all kinds of weird situations (e.g., double allocations, list corruptions, unmovable allocations ending up in the movable zone).

This creates the very fringe condition where the client was added, failed during add and didn't set the client_data. The core code will then still call other client_data centric ops like remove(), rename(), get_nl_info(), and get_net_dev_by_params() with NULL client_data - which is confusing and unexpected. If the add() callback fails, then do not call any more client ops for the device, even remove. Remove all the now redundant checks for NULL client_data in ops callbacks. Update all the add() callbacks to return error codes appropriately. EOPNOTSUPP is used for cases where the ULP does not support the ib_device - eg because it only works with IB.

FAILED: patch "[PATCH] RDMA: Allow ib_client's to fail when add() is called" failed to apply to 5.6-stable tree

The patch below does not apply to the 5.6-stable tree. If someone wants it applied there, or to any other stable or longterm tree, then please email the backport, including the original git commit id to <stable(a)vger.kernel.org>. thanks, greg k-h ------------------ original commit in Linus's tree ------------------ >From 11a0ae4c4bff9b2a471b54dbe910fc0f60e58e62 Mon Sep 17 00:00:00 2001 From: Jason Gunthorpe <jgg(a)ziepe.ca> Date: Tue, 21 Apr 2020 20:24:40 +0300 Subject: [PATCH] RDMA: Allow ib_client's to fail when add() is called When a client is added it isn't allowed to fail, but all the client's have various failure paths within their add routines. This creates the very fringe condition where the client was added, failed during add and didn't set the client_data. The core code will then still call other client_data centric ops like remove(), rename(), get_nl_info(), and get_net_dev_by_params() with NULL client_data - which is confusing and unexpected. If the add() callback fails, then do not call any more client ops for the device, even remove. Remove all the now redundant checks for NULL client_data in ops callbacks. Update all the add() callbacks to return error codes appropriately. EOPNOTSUPP is used for cases where the ULP does not support the ib_device - eg because it only works with IB.

Please apply backport of commit da2311a6385c ("can: kvaser_usb: kvaser_usb_leaf: Fix some info-leaks to USB devices") to v4.9.y

by Salvatore Bonaccorso

Hi The issue fixed with da2311a6385c ("can: kvaser_usb: kvaser_usb_leaf: Fix some info-leaks to USB devices") seem to be present as well before 4.19, introduced in 3.8 by commit 080f40a6fa28 "can: kvaser_usb: Add support for Kvaser CAN/USB devices" already. For Debian (for 4.9.210-1 upload) and for 3.16.y upstream Ben Hutchings did backport the commit. Can you apply it please as well for v4.9.y?

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 21998a351512eba4ed5969006f0c55882d995ada Mon Sep 17 00:00:00 2001 From: Anthony Steinhauser <asteinhauser(a)google.com> Date: Tue, 19 May 2020 06:40:42 -0700 Subject: [PATCH] x86/speculation: Avoid force-disabling IBPB based on STIBP and enhanced IBRS. When STIBP is unavailable or enhanced IBRS is available, Linux force-disables the IBPB mitigation of Spectre-BTB even when simultaneous multithreading is disabled. While attempts to enable IBPB using prctl(PR_SET_SPECULATION_CTRL, PR_SPEC_INDIRECT_BRANCH, ...) fail with EPERM, the seccomp syscall (or its prctl(PR_SET_SECCOMP, ...) equivalent) which are used e.g. by Chromium or OpenSSH succeed with no errors but the application remains silently vulnerable to cross-process Spectre v2 attacks (classical BTB poisoning). At the same time the SYSFS reporting (/sys/devices/system/cpu/vulnerabilities/spectre_v2) displays that IBPB is conditionally enabled when in fact it is unconditionally disabled. STIBP is useful only when SMT is enabled. When SMT is disabled and STIBP is unavailable, it makes no sense to force-disable also IBPB, because IBPB protects against cross-process Spectre-BTB attacks regardless of the SMT state. At the same time since missing STIBP was only observed on AMD CPUs, AMD does not recommend using STIBP, but recommends using IBPB, so disabling IBPB because of missing STIBP goes directly against AMD's advice: https://developer.amd.com/wp-content/resources/Architecture_Guidelines_Upda… Similarly, enhanced IBRS is designed to protect cross-core BTB poisoning and BTB-poisoning attacks from user space against kernel (and BTB-poisoning attacks from guest against hypervisor), it is not designed to prevent cross-process (or cross-VM) BTB poisoning between processes (or VMs) running on the same core. Therefore, even with enhanced IBRS it is necessary to flush the BTB during context-switches, so there is no reason to force disable IBPB when enhanced IBRS is available. Enable the prctl control of IBPB even when STIBP is unavailable or enhanced IBRS is available.

For that, we dump them in a per-CPU data structure (the so called host context).

[PATCH 0/4] bootconfig: Fix quote-character issue and return value

by Masami Hiramatsu

Hi Steve, I found 2 bugs in /proc/bootconfig and tools/bootconfig. - They always use double-quote to quote values. For the values which includes double-quote, it should use single-quote instead. - tools/bootconfig always returns error code if it shows the bootconfig in initrd (executed without options) This series fixes those bugs and add testcases to ensure no regressions. Thank you, --- Masami Hiramatsu (4): proc/bootconfig: Fix to use correct quotes for value tools/bootconfig: Fix to use correct quotes for value tools/bootconfig: Fix to return 0 if succeeded to show the bootconfig tools/bootconfig: Add testcase for show-command and quotes test fs/proc/bootconfig.c | 13 +++++++++---- tools/bootconfig/main.c | 18 +++++++++++------- tools/bootconfig/test-bootconfig.sh | 10 ++++++++++ 3 files changed, 30 insertions(+), 11 deletions(-) -- Masami Hiramatsu (Linaro) <mhiramat(a)kernel.org>

As you comment, I modified my patch. 1) I revised three patch so version is 3. 2) I misunderstood your comment(adding annotation) firstly. But, I clearly know at now and modified it. the annotation before "ovl_setup_trap" is clearly understood as I see. And I have some questions. 1) As I understand, The CC you said valid is 'linux-unionfs'? 2) The comment "Please add these lines to the bottom of commit message..." Is it needed manually when I revised patch?

[PATCH 1/2] e1000e: Do not wake up the system via WOL if device wakeup is disabled

by Chen Yu

Currently the system will be woken up via WOL(Wake On Lan) even if the device wakeup ability has been disabled via sysfs: cat /sys/devices/pci0000:00/0000:00:1f.6/power/wakeup disabled The system should not be woken up if the user has explicitly disabled the wake up ability for this device. This patch clears the WOL ability of this network device if the user has disabled the wake up ability in sysfs. Fixes: bc7f75fa9788 ("[E1000E]: New pci-express e1000 driver") Reported-by: Rafael J.

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 9dd277ff92d06f6aa95b39936ad83981d781f49b Mon Sep 17 00:00:00 2001 From: Lukas Wunner <lukas(a)wunner.de> Date: Fri, 15 May 2020 17:58:02 +0200 Subject: [PATCH] spi: bcm2835: Fix controller unregister order The BCM2835 SPI driver uses devm_spi_register_controller() on bind. As a consequence, on unbind, __device_release_driver() first invokes bcm2835_spi_remove() before unregistering the SPI controller via devres_release_all(). This order is incorrect: bcm2835_spi_remove() tears down the DMA channels and turns off the SPI controller, including its interrupts and clock. The SPI controller is thus no longer usable. When the SPI controller is subsequently unregistered, it unbinds all its slave devices. If their drivers need to access the SPI bus, e.g. to quiesce their interrupts, unbinding will fail. As a rule, devm_spi_register_controller() must not be used if the ->remove() hook performs teardown steps which shall be performed after unbinding of slaves. Fix by using the non-devm variant spi_register_controller(). Note that the struct spi_controller as well as the driver-private data are not freed until after bcm2835_spi_remove() has finished, so accessing them is safe.

[PATCH v4 11/11] seccomp: Fix ioctl number for SECCOMP_IOCTL_NOTIF_ID_VALID

by Kees Cook

When SECCOMP_IOCTL_NOTIF_ID_VALID was first introduced it had the wrong direction flag set. While this isn't a big deal as nothing currently enforces these bits in the kernel, it should be defined correctly. Fix the define and provide support for the old command until it is no longer needed for backward compatibility.

It's caused by reuse the memory of request structure. In crypto_authenc_init_tfm(), the reqsize is set to: [PART 1] sizeof(authenc_request_ctx) + [PART 2] ictx->reqoff + [PART 3] MAX(ahash part, skcipher part) and the 'PART 3' is used by both ahash and skcipher in turn. When the virtio_crypto driver finish skcipher req, it'll call ->complete callback(in crypto_finalize_skcipher_request) and then free its resources whose pointers are recorded in 'skcipher parts'. However, the ->complete is 'crypto_authenc_encrypt_done' in this case, it will use the 'ahash part' of the request and change its content, so virtio_crypto driver will get the wrong pointer after ->complete finish and mistakenly free some other's memory. So the system will crash when these memory will be used again. The resources which need to be cleaned up are not used any more. But the pointers of these resources may be changed in the function "crypto_finalize_skcipher_request". Thus release specific resources before calling this function.

FAILED: patch "[PATCH] spi: pxa2xx: Fix runtime PM ref imbalance on probe error" failed to apply to 4.19-stable tree

by gregkh＠linuxfoundation.org

The patch below does not apply to the 4.19-stable tree. If someone wants it applied there, or to any other stable or longterm tree, then please email the backport, including the original git commit id to <stable(a)vger.kernel.org>. thanks, greg k-h ------------------ original commit in Linus's tree ------------------ >From 65e318e17358a3fd4fcb5a69d89b14016dee2f06 Mon Sep 17 00:00:00 2001 From: Lukas Wunner <lukas(a)wunner.de> Date: Mon, 25 May 2020 14:25:03 +0200 Subject: [PATCH] spi: pxa2xx: Fix runtime PM ref imbalance on probe error The PXA2xx SPI driver releases a runtime PM ref in the probe error path even though it hasn't acquired a ref earlier.

FAILED: patch "[PATCH] spi: pxa2xx: Fix controller unregister order" failed to apply to 4.19-stable tree

If someone wants it applied there, or to any other stable or longterm tree, then please email the backport, including the original git commit id to <stable(a)vger.kernel.org>. thanks, greg k-h ------------------ original commit in Linus's tree ------------------ >From 32e5b57232c0411e7dea96625c415510430ac079 Mon Sep 17 00:00:00 2001 From: Lukas Wunner <lukas(a)wunner.de> Date: Mon, 25 May 2020 14:25:02 +0200 Subject: [PATCH] spi: pxa2xx: Fix controller unregister order The PXA2xx SPI driver uses devm_spi_register_controller() on bind. As a consequence, on unbind, __device_release_driver() first invokes pxa2xx_spi_remove() before unregistering the SPI controller via devres_release_all(). This order is incorrect: pxa2xx_spi_remove() disables the chip, rendering the SPI bus inaccessible even though the SPI controller is still registered. When the SPI controller is subsequently unregistered, it unbinds all its slave devices. Because their drivers cannot access the SPI bus, e.g. to quiesce interrupts, the slave devices may be left in an improper state. As a rule, devm_spi_register_controller() must not be used if the ->remove() hook performs teardown steps which shall be performed after unregistering the controller and specifically after unbinding of slaves. Fix by reverting to the non-devm variant of spi_register_controller(). An alternative approach would be to use device-managed functions for all steps in pxa2xx_spi_remove(), e.g. by calling devm_add_action_or_reset() on probe. However that approach would add more LoC to the driver and it wouldn't lend itself as well to backporting to stable. The improper use of devm_spi_register_controller() was introduced in 2013 by commit a807fcd090d6 ("spi: pxa2xx: use devm_spi_register_master()"), but all earlier versions of the driver going back to 2006 were likewise broken because they invoked spi_unregister_master() at the end of pxa2xx_spi_remove(), rather than at the beginning.

[PATCH stable 4.19, 5.4] x86/mm: Change so poison pages are either unmapped or marked uncacheable

by Tony Luck

From: "Luck, Tony" <tony.luck(a)intel.com> commit 17fae1294ad9d711b2c3dd0edef479d40c76a5e8 upstream An interesting thing happened when a guest Linux instance took a machine check. The VMM unmapped the bad page from guest physical space and passed the machine check to the guest. Linux took all the normal actions to offline the page from the process that was using it. But then guest Linux crashed because it said there was a second machine check inside the kernel with this stack trace: do_memory_failure set_mce_nospec set_memory_uc _set_memory_uc change_page_attr_set_clr cpa_flush clflush_cache_range_opt This was odd, because a CLFLUSH instruction shouldn't raise a machine check (it isn't consuming the data). Further investigation showed that the VMM had passed in another machine check because is appeared that the guest was accessing the bad page. Fix is to check the scope of the poison by checking the MCi_MISC register. If the entire page is affected, then unmap the page. If only part of the page is affected, then mark the page as uncacheable. This assumes that VMMs will do the logical thing and pass in the "whole page scope" via the MCi_MISC register (since they unmapped the entire page).

Please add 17839856fd58 to the stable queue

by Linus Torvalds

Commit 17839856fd58 ("gup: document and work around "COW can break either way" issue") is a real fix, but wasn't marked for stable because I wanted it to get more coverage testing in mainline first. Not because the patch is all that complex or scary, but because I was worried we'd find some odd case where it would make things slower by triggering the GUP slowpath much more often due to people doing odd things. It turns out my worry seems to have been misplaced. The kernel test robot did indeed trigger a case where this made a big difference, but rather than being bad, it improved the odd corner-case test-case performance by a factor of 20x by breaking the COW and triggering the fast-case code that way, rather than the other way around. See https://lore.kernel.org/lkml/20200611040453.GK12456@shao2-debian/ for details. So that commit fixes a bug, isn't expected to really make any difference on any sane workload, and can apparently help the crazy cases by a huge amount. Let's just push it to stable.. Linus

Currently, it is possible to enable indirect branch speculation even after it was force-disabled using the PR_SPEC_FORCE_DISABLE option. Moreover, the PR_GET_SPECULATION_CTRL command gives afterwards an incorrect result (force-disabled when it is in fact enabled). This also is inconsistent vs. STIBP and the documention which cleary states that PR_SPEC_FORCE_DISABLE cannot be undone. Fix this by actually enforcing force-disabled indirect branch speculation. PR_SPEC_ENABLE called after PR_SPEC_FORCE_DISABLE now fails with -EPERM as described in the documentation.

[PATCH] drm/i915: Include asm sources for {ivb,hsw}_clear_kernel.c

by Rodrigo Vivi

Alexandre Oliva has recently removed these files from Linux Libre with concerns that the sources weren't available. The sources are available on IGT repository, and only open source tools are used to generate the {ivb,hsw}_clear_kernel.c files. However, the remaining concern from Alexandre Oliva was around GPL license and the source not been present when distributing the code. So, it looks like 2 alternatives are possible, the use of linux-firmware.git repository to store the blob or making sure that the source is also present in our tree. Since the goal is to limit the i915 firmware to only the micro-controller blobs let's make sure that we do include the asm sources here in our tree. Btw, I tried to have some diligence here and make sure that the asms that these commits are adding are truly the source for the mentioned files: ./scripts/generate_clear_kernel.sh -g ivb -m /home/vivijim/intel/freedesktop.org/mesa/mesa/build/src/intel/tools/i965_asm igt$ ./scripts/generate_clear_kernel.sh -g ivb -m /home/vivijim/intel/freedesktop.org/mesa/mesa/build/src/intel/tools/i965_asm Output file not specified - using default file "ivb-cb_assembled" Generating gen7 CB Kernel assembled file "ivb_clear_kernel.c" for i915 driver... igt$ diff /home/vivijim/i915/drm-tip/drivers/gpu/drm/i915/gt/ivb_clear_kernel.c ivb_clear_kernel.c 5c5 < * Generated by: IGT Gpu Tools on Fri 21 Feb 2020 05:29:32 AM UTC --- > * Generated by: IGT Gpu Tools on Mon 08 Jun 2020 10:00:54 AM PDT 61c61 < }; --- > }; \ No newline at end of file igt$ ./scripts/generate_clear_kernel.sh -g hsw -m /hom e/vivijim/intel/freedesktop.org/mesa/mesa/build/src/intel/tools/i965_asm Output file not specified - using default file "hsw-cb_assembled" Generating gen7.5 CB Kernel assembled file "hsw_clear_kernel.c" for i915 driver... igt$ diff /home/vivijim/i915/drm-tip/drivers/gpu/drm/i915/gt/hsw_clear_kernel.c hsw_clear_kernel.c 5c5 < * Generated by: IGT Gpu Tools on Fri 21 Feb 2020 05:30:13 AM UTC --- > * Generated by: IGT Gpu Tools on Mon 08 Jun 2020 10:01:42 AM PDT 61c61 < }; --- > }; \ No newline at end of file Used IGT and Mesa master repositories from Fri Jun 5 2020) IGT: 53e8c878a6fb ("tests/kms_chamelium: Force reprobe after replugging the connector") Mesa: 5d13c7477eb1 ("radv: set keep_statistic_info with RADV_DEBUG=shaderstats") Mesa built with: meson build -D platforms=drm,x11 -D dri-drivers=i965 -D gallium-drivers=iris -D prefix=/usr -D libdir=/usr/lib64/ -Dtools=intel -Dkulkan-drivers=intel && ninja -C build Reference: http://www.fsfla.org/pipermail/linux-libre/2020-June/003374.html Reference: http://www.fsfla.org/pipermail/linux-libre/2020-June/003375.html Fixes: 47f8253d2b89 ("drm/i915/gen7: Clear all EU/L3 residual contexts") Cc: <stable(a)vger.kernel.org> # v5.7+ Cc: Alexandre Oliva <lxoliva(a)fsfla.org> Cc: Prathap Kumar Valsan <prathap.kumar.valsan(a)intel.com> Cc: Akeem G Abodunrin <akeem.g.abodunrin(a)intel.com> Cc: Mika Kuoppala <mika.kuoppala(a)linux.intel.com> Cc: Chris Wilson <chris(a)chris-wilson.co.uk> Cc: Jani Nikula <jani.nikula(a)intel.com> Cc: Joonas Lahtinen <joonas.lahtinen(a)linux.intel.com> Signed-off-by: Rodrigo Vivi <rodrigo.vivi(a)intel.com> --- .../drm/i915/gt/shaders/clear_kernel/hsw.asm | 141 ++++++++++++++++++ .../drm/i915/gt/shaders/clear_kernel/ivb.asm | 139 +++++++++++++++++ 2 files changed, 280 insertions(+) create mode 100644 drivers/gpu/drm/i915/gt/shaders/clear_kernel/hsw.asm create mode 100644 drivers/gpu/drm/i915/gt/shaders/clear_kernel/ivb.asm diff --git a/drivers/gpu/drm/i915/gt/shaders/clear_kernel/hsw.asm b/drivers/gpu/drm/i915/gt/shaders/clear_kernel/hsw.asm new file mode 100644 index 000000000000..bc29baf22c61 --- /dev/null +++ b/drivers/gpu/drm/i915/gt/shaders/clear_kernel/hsw.asm @@ -0,0 +1,141 @@ +/* SPDX-License-Identifier: MIT */ +/* + * Copyright © 2020 Intel Corporation + * + * Permission is hereby granted, free of charge, to any person obtaining a + * copy of this software and associated documentation files (the "Software"), + * to deal in the Software without restriction, including without limitation + * the rights to use, copy, modify, merge, publish, distribute, sublicense, + * and/or sell copies of the Software, and to permit persons to whom the + * Software is furnished to do so, subject to the following conditions: + * + * The above copyright notice and this permission notice (including the next + * paragraph) shall be included in all copies or substantial portions of the + * Software. + * + * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR + * IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, + * FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

[PATCH stable 5.6, 5.7] x86/mm: Change so poison pages are either unmapped or marked uncacheable

by Tony Luck

From: "Luck, Tony" <tony.luck(a)intel.com> commit 17fae1294ad9d711b2c3dd0edef479d40c76a5e8 upstream An interesting thing happened when a guest Linux instance took a machine check. The VMM unmapped the bad page from guest physical space and passed the machine check to the guest. Linux took all the normal actions to offline the page from the process that was using it. But then guest Linux crashed because it said there was a second machine check inside the kernel with this stack trace: do_memory_failure set_mce_nospec set_memory_uc _set_memory_uc change_page_attr_set_clr cpa_flush clflush_cache_range_opt This was odd, because a CLFLUSH instruction shouldn't raise a machine check (it isn't consuming the data). Further investigation showed that the VMM had passed in another machine check because is appeared that the guest was accessing the bad page. Fix is to check the scope of the poison by checking the MCi_MISC register. If the entire page is affected, then unmap the page. If only part of the page is affected, then mark the page as uncacheable. This assumes that VMMs will do the logical thing and pass in the "whole page scope" via the MCi_MISC register (since they unmapped the entire page).

These are split in two parts, as in "[high 11111 low]", to thwart any attempt to use these bits in an L1TF attack. This works as long as there are 5 free bits between MAXPHYADDR and bit 50 (inclusive), leaving bit 51 free so that the MMIO access triggers a reserved-bit-set page fault. The bit positions however were computed wrongly for AMD processors that have encryption support. In this case, x86_phys_bits is reduced (for example from 48 to 43, to account for the C bit at position 47 and four bits used internally to store the SEV ASID and other stuff) while x86_cache_bits in would remain set to 48, and _all_ bits between the reduced MAXPHYADDR and bit 51 are set. Then low_phys_bits would also cover some of the bits that are set in the shadow_mmio_value, terribly confusing the gfn caching mechanism. To fix this, avoid splitting gfns as long as the processor does not have the L1TF bug (which includes all AMD processors). When there is no splitting, low_phys_bits can be set to the reduced MAXPHYADDR removing the overlap. This fixes "npt=0" operation on EPYC processors. Thanks to Maxim Levitsky for bisecting this bug.

FAILED: patch "[PATCH] spi: pxa2xx: Fix controller unregister order" failed to apply to 4.4-stable tree

If someone wants it applied there, or to any other stable or longterm tree, then please email the backport, including the original git commit id to <stable(a)vger.kernel.org>. thanks, greg k-h ------------------ original commit in Linus's tree ------------------ >From 32e5b57232c0411e7dea96625c415510430ac079 Mon Sep 17 00:00:00 2001 From: Lukas Wunner <lukas(a)wunner.de> Date: Mon, 25 May 2020 14:25:02 +0200 Subject: [PATCH] spi: pxa2xx: Fix controller unregister order The PXA2xx SPI driver uses devm_spi_register_controller() on bind. As a consequence, on unbind, __device_release_driver() first invokes pxa2xx_spi_remove() before unregistering the SPI controller via devres_release_all(). This order is incorrect: pxa2xx_spi_remove() disables the chip, rendering the SPI bus inaccessible even though the SPI controller is still registered. When the SPI controller is subsequently unregistered, it unbinds all its slave devices. Because their drivers cannot access the SPI bus, e.g. to quiesce interrupts, the slave devices may be left in an improper state. As a rule, devm_spi_register_controller() must not be used if the ->remove() hook performs teardown steps which shall be performed after unregistering the controller and specifically after unbinding of slaves. Fix by reverting to the non-devm variant of spi_register_controller(). An alternative approach would be to use device-managed functions for all steps in pxa2xx_spi_remove(), e.g. by calling devm_add_action_or_reset() on probe. However that approach would add more LoC to the driver and it wouldn't lend itself as well to backporting to stable.

The VMM unmapped the bad page from guest physical space and passed the machine check to the guest. Linux took all the normal actions to offline the page from the process that was using it. But then guest Linux crashed because it said there was a second machine check inside the kernel with this stack trace: do_memory_failure set_mce_nospec set_memory_uc _set_memory_uc change_page_attr_set_clr cpa_flush clflush_cache_range_opt This was odd, because a CLFLUSH instruction shouldn't raise a machine check (it isn't consuming the data). Further investigation showed that the VMM had passed in another machine check because is appeared that the guest was accessing the bad page. Fix is to check the scope of the poison by checking the MCi_MISC register. If the entire page is affected, then unmap the page. If only part of the page is affected, then mark the page as uncacheable. This assumes that VMMs will do the logical thing and pass in the "whole page scope" via the MCi_MISC register (since they unmapped the entire page).

The VMM unmapped the bad page from guest physical space and passed the machine check to the guest. Linux took all the normal actions to offline the page from the process that was using it. But then guest Linux crashed because it said there was a second machine check inside the kernel with this stack trace: do_memory_failure set_mce_nospec set_memory_uc _set_memory_uc change_page_attr_set_clr cpa_flush clflush_cache_range_opt This was odd, because a CLFLUSH instruction shouldn't raise a machine check (it isn't consuming the data). Further investigation showed that the VMM had passed in another machine check because is appeared that the guest was accessing the bad page. Fix is to check the scope of the poison by checking the MCi_MISC register. If the entire page is affected, then unmap the page. If only part of the page is affected, then mark the page as uncacheable. This assumes that VMMs will do the logical thing and pass in the "whole page scope" via the MCi_MISC register (since they unmapped the entire page).

[PATCH v2 1/3] spi: spi-fsl-dspi: Fix external abort on interrupt in exit paths

If interrupt comes late, during probe error path or device remove (could be triggered with CONFIG_DEBUG_SHIRQ), the interrupt handler dspi_interrupt() will access registers with the clock being disabled.

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 e649b3f0188f8fd34dd0dde8d43fd3312b902fb2 Mon Sep 17 00:00:00 2001 From: Eiichi Tsukata <eiichi.tsukata(a)nutanix.com> Date: Sat, 6 Jun 2020 13:26:27 +0900 Subject: [PATCH] KVM: x86: Fix APIC page invalidation race Commit b1394e745b94 ("KVM: x86: fix APIC page invalidation") tried to fix inappropriate APIC page invalidation by re-introducing arch specific kvm_arch_mmu_notifier_invalidate_range() and calling it from kvm_mmu_notifier_invalidate_range_start. However, the patch left a possible race where the VMCS APIC address cache is updated *before* it is unmapped: (Invalidator) kvm_mmu_notifier_invalidate_range_start() (Invalidator) kvm_make_all_cpus_request(kvm, KVM_REQ_APIC_PAGE_RELOAD) (KVM VCPU) vcpu_enter_guest() (KVM VCPU) kvm_vcpu_reload_apic_access_page() (Invalidator) actually unmap page Because of the above race, there can be a mismatch between the host physical address stored in the APIC_ACCESS_PAGE VMCS field and the host physical address stored in the EPT entry for the APIC GPA (0xfee0000). When this happens, the processor will not trap APIC accesses, and will instead show the raw contents of the APIC-access page. Because Windows OS periodically checks for unexpected modifications to the LAPIC register, this will show up as a BSOD crash with BugCheck CRITICAL_STRUCTURE_CORRUPTION (109) we are currently seeing in https://bugzilla.redhat.com/show_bug.cgi?id=1751017. The root cause of the issue is that kvm_arch_mmu_notifier_invalidate_range() cannot guarantee that no additional references are taken to the pages in the range before kvm_mmu_notifier_invalidate_range_end().

When STIBP is unavailable or enhanced IBRS is available, Linux force-disables the IBPB mitigation of Spectre-BTB even when simultaneous multithreading is disabled. While attempts to enable IBPB using prctl(PR_SET_SPECULATION_CTRL, PR_SPEC_INDIRECT_BRANCH, ...) fail with EPERM, the seccomp syscall (or its prctl(PR_SET_SECCOMP, ...) equivalent) which are used e.g. by Chromium or OpenSSH succeed with no errors but the application remains silently vulnerable to cross-process Spectre v2 attacks (classical BTB poisoning).

FAILED: patch "[PATCH] x86/speculation: Avoid force-disabling IBPB based on STIBP" failed to apply to 4.14-stable tree

by gregkh＠linuxfoundation.org

The patch below does not apply to the 4.14-stable tree. If someone wants it applied there, or to any other stable or longterm tree, then please email the backport, including the original git commit id to <stable(a)vger.kernel.org>. thanks, greg k-h ------------------ original commit in Linus's tree ------------------ >From 21998a351512eba4ed5969006f0c55882d995ada Mon Sep 17 00:00:00 2001 From: Anthony Steinhauser <asteinhauser(a)google.com> Date: Tue, 19 May 2020 06:40:42 -0700 Subject: [PATCH] x86/speculation: Avoid force-disabling IBPB based on STIBP and enhanced IBRS. When STIBP is unavailable or enhanced IBRS is available, Linux force-disables the IBPB mitigation of Spectre-BTB even when simultaneous multithreading is disabled. While attempts to enable IBPB using prctl(PR_SET_SPECULATION_CTRL, PR_SPEC_INDIRECT_BRANCH, ...) fail with EPERM, the seccomp syscall (or its prctl(PR_SET_SECCOMP, ...) equivalent) which are used e.g. by Chromium or OpenSSH succeed with no errors but the application remains silently vulnerable to cross-process Spectre v2 attacks (classical BTB poisoning). At the same time the SYSFS reporting (/sys/devices/system/cpu/vulnerabilities/spectre_v2) displays that IBPB is conditionally enabled when in fact it is unconditionally disabled. STIBP is useful only when SMT is enabled. When SMT is disabled and STIBP is unavailable, it makes no sense to force-disable also IBPB, because IBPB protects against cross-process Spectre-BTB attacks regardless of the SMT state. At the same time since missing STIBP was only observed on AMD CPUs, AMD does not recommend using STIBP, but recommends using IBPB, so disabling IBPB because of missing STIBP goes directly against AMD's advice: https://developer.amd.com/wp-content/resources/Architecture_Guidelines_Upda… Similarly, enhanced IBRS is designed to protect cross-core BTB poisoning and BTB-poisoning attacks from user space against kernel (and BTB-poisoning attacks from guest against hypervisor), it is not designed to prevent cross-process (or cross-VM) BTB poisoning between processes (or VMs) running on the same core. Therefore, even with enhanced IBRS it is necessary to flush the BTB during context-switches, so there is no reason to force disable IBPB when enhanced IBRS is available. Enable the prctl control of IBPB even when STIBP is unavailable or enhanced IBRS is available.

These are split in two parts, as in "[high 11111 low]", to thwart any attempt to use these bits in an L1TF attack. This works as long as there are 5 free bits between MAXPHYADDR and bit 50 (inclusive), leaving bit 51 free so that the MMIO access triggers a reserved-bit-set page fault. The bit positions however were computed wrongly for AMD processors that have encryption support. In this case, x86_phys_bits is reduced (for example from 48 to 43, to account for the C bit at position 47 and four bits used internally to store the SEV ASID and other stuff) while x86_cache_bits in would remain set to 48, and _all_ bits between the reduced MAXPHYADDR and bit 51 are set. Then low_phys_bits would also cover some of the bits that are set in the shadow_mmio_value, terribly confusing the gfn caching mechanism. To fix this, avoid splitting gfns as long as the processor does not have the L1TF bug (which includes all AMD processors). When there is no splitting, low_phys_bits can be set to the reduced MAXPHYADDR removing the overlap. This fixes "npt=0" operation on EPYC processors. Thanks to Maxim Levitsky for bisecting this bug.

Its filename was usercopy-mark-dma-kmalloc-caches-as-usercopy-caches.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Vlastimil Babka <vbabka(a)suse.cz> Subject: usercopy: mark dma-kmalloc caches as usercopy caches We have seen a "usercopy: Kernel memory overwrite attempt detected to SLUB object 'dma-kmalloc-1 k' (offset 0, size 11)!" error on s390x, as IUCV uses kmalloc() with __GFP_DMA because of memory address restrictions. The issue has been discussed [2] and it has been noted that if all the kmalloc caches are marked as usercopy, there's little reason not to mark dma-kmalloc caches too. The 'dma' part merely means that __GFP_DMA is used to restrict memory address range. As Jann Horn put it [3]: "I think dma-kmalloc slabs should be handled the same way as normal kmalloc slabs. When a dma-kmalloc allocation is freshly created, it is just normal kernel memory - even if it might later be used for DMA -, and it should be perfectly fine to copy_from_user() into such allocations at that point, and to copy_to_user() out of them at the end. If you look at the places where such allocations are created, you can see things like kmemdup(), memcpy() and so on - all normal operations that shouldn't conceptually be different from usercopy in any relevant way." Thus this patch marks the dma-kmalloc-* caches as usercopy.

[tip: x86/urgent] x86/cpu: Reinitialize IA32_FEAT_CTL MSR on BSP during wakeup

This fixes a bug where IA32_FEAT_CTL is left uninitialized and results in VMXON taking a #GP due to VMX not being fully enabled, i.e. breaks KVM. Use init_ia32_feat_ctl() to "restore" IA32_FEAT_CTL as it already deals with the case where the MSR is locked, and because APs already redo init_ia32_feat_ctl() during suspend by virtue of the SMP boot flow being used to reinitialize APs upon wakeup. Do the call in the early wakeup flow to avoid dependencies in the syscore_ops chain, e.g. simply adding a resume hook is not guaranteed to work, as KVM does VMXON in its own resume hook, kvm_resume(), when KVM has active guests.

[PATCH] acpi: disallow loading configfs acpi tables when locked down

by Jason A. Donenfeld

Like other vectors already patched, this one here allows the root user to load ACPI tables, which enables arbitrary physical address writes, which in turn makes it possible to disable lockdown. This patch prevents this by checking the lockdown status before allowing a new ACPI table to be installed. The link in the trailer shows a PoC of how this might be used.

[PATCH 1/2] spi: spi-fsl-dspi: Fix external abort on interrupt in exit paths

by Krzysztof Kozlowski

If interrupt comes late, during probe error path or device remove (could be triggered with CONFIG_DEBUG_SHIRQ), the interrupt handler dspi_interrupt() will access registers with the clock being disabled.

[PATCH v3 1/4] fs, net: Standardize on file_receive helper to move fds across processes

by Sargun Dhillon

Previously there were two chunks of code where the logic to receive file descriptors was duplicated in net. The compat version of copying file descriptors via SCM_RIGHTS did not have logic to update cgroups. Logic to change the cgroup data was added in: commit 48a87cc26c13 ("net: netprio: fd passed in SCM_RIGHTS datagram not set correctly") commit d84295067fc7 ("net: net_cls: fd passed in SCM_RIGHTS datagram not set correctly") This was not copied to the compat path. This commit fixes that, and thus should be cherry-picked into stable. This introduces a helper (file_receive) which encapsulates the logic for handling calling security hooks as well as manipulating cgroup information. This helper can then be used other places in the kernel where file descriptors are copied between processes I tested cgroup classid setting on both the compat (x32) path, and the native path to ensure that when moving the file descriptor the classid is set.

[PATCH] i2c: imx: Fix external abort on early interrupt

If interrupt comes early (could be triggered with CONFIG_DEBUG_SHIRQ), the i2c_imx_isr() will access registers before the I2C hardware is initialized. This leads to external abort on non-linefetch on Toradex Colibri VF50 module (with Vybrid VF5xx): Unhandled fault: external abort on non-linefetch (0x1008) at 0x8882d003 Internal error: : 1008 [#1] ARM Modules linked in: CPU: 0 PID: 1 Comm: swapper Not tainted 5.7.0 #607 Hardware name: Freescale Vybrid VF5xx/VF6xx (Device Tree) (i2c_imx_isr) from [<8017009c>] (free_irq+0x25c/0x3b0) (free_irq) from [<805844ec>] (release_nodes+0x178/0x284) (release_nodes) from [<80580030>] (really_probe+0x10c/0x348) (really_probe) from [<80580380>] (driver_probe_device+0x60/0x170) (driver_probe_device) from [<80580630>] (device_driver_attach+0x58/0x60) (device_driver_attach) from [<805806bc>] (__driver_attach+0x84/0xc0) (__driver_attach) from [<8057e228>] (bus_for_each_dev+0x68/0xb4) (bus_for_each_dev) from [<8057f3ec>] (bus_add_driver+0x144/0x1ec) (bus_add_driver) from [<80581320>] (driver_register+0x78/0x110) (driver_register) from [<8010213c>] (do_one_initcall+0xa8/0x2f4) (do_one_initcall) from [<80c0100c>] (kernel_init_freeable+0x178/0x1dc) (kernel_init_freeable) from [<80807048>] (kernel_init+0x8/0x110) (kernel_init) from [<80100114>] (ret_from_fork+0x14/0x20) Additionally, the i2c_imx_isr() could wake up the wait queue (imx_i2c_struct->queue) before its initialization happens.

[PATCH 2/4] writeback: Avoid skipping inode writeback

by Jan Kara

Inode's i_io_list list head is used to attach inode to several different lists - wb->{b_dirty, b_dirty_time, b_io, b_more_io}. When flush worker prepares a list of inodes to writeback e.g. for sync(2), it moves inodes to b_io list. Thus it is critical for sync(2) data integrity guarantees that inode is not requeued to any other writeback list when inode is queued for processing by flush worker. That's the reason why writeback_single_inode() does not touch i_io_list (unless the inode is completely clean) and why __mark_inode_dirty() does not touch i_io_list if I_SYNC flag is set. However there are two flaws in the current logic: 1) When inode has only I_DIRTY_TIME set but it is already queued in b_io list due to sync(2), concurrent __mark_inode_dirty(inode, I_DIRTY_SYNC) can still move inode back to b_dirty list resulting in skipping writeback of inode time stamps during sync(2). 2) When inode is on b_dirty_time list and writeback_single_inode() races with __mark_inode_dirty() like: writeback_single_inode() __mark_inode_dirty(inode, I_DIRTY_PAGES) inode->i_state |= I_SYNC __writeback_single_inode() inode->i_state |= I_DIRTY_PAGES; if (inode->i_state & I_SYNC) bail if (!(inode->i_state & I_DIRTY_ALL)) - not true so nothing done We end up with I_DIRTY_PAGES inode on b_dirty_time list and thus standard background writeback will not writeback this inode leading to possible dirty throttling stalls etc. (thanks to Martijn Coenen for this analysis). Fix these problems by tracking whether inode is queued in b_io or b_more_io lists in a new I_SYNC_QUEUED flag. When this flag is set, we know flush worker has queued inode and we should not touch i_io_list. On the other hand we also know that once flush worker is done with the inode it will requeue the inode to appropriate dirty list. When I_SYNC_QUEUED is not set, __mark_inode_dirty() can (and must) move inode to appropriate dirty list.

[PATCH 3/4] writeback: Fix sync livelock due to b_dirty_time processing

by Jan Kara

When we are processing writeback for sync(2), move_expired_inodes() didn't set any inode expiry value (older_than_this). This can result in writeback never completing if there's steady stream of inodes added to b_dirty_time list as writeback rechecks dirty lists after each writeback round whether there's more work to be done. Fix the problem by using sync(2) start time is inode expiry value when processing b_dirty_time list similarly as for ordinarily dirtied inodes. This requires some refactoring of older_than_this handling which simplifies the code noticeably as a bonus.

From: Hans de Goede <hdegoede(a)redhat.com> Before commit cfc4c189bc70 ("pwm: Read initial hardware state at request time"), a driver's get_state callback would get called once per PWM from pwmchip_add(). pwm-lpss' runtime-pm code was relying on this, getting a runtime-pm ref for PWMs which are enabled at probe time from within its get_state callback, before enabling runtime-pm. The change to calling get_state at request time causes a number of problems: 1. PWMs enabled at probe time may get runtime suspended before they are requested, causing e.g. a LCD backlight controlled by the PWM to turn off. 2. When the request happens when the PWM has been runtime suspended, the ctrl register will read all 1 / 0xffffffff, causing get_state to store bogus values in the pwm_state. 3. get_state was using an async pm_runtime_get() call, because it assumed that runtime-pm has not been enabled yet. If shortly after the request an apply call is made, then the pwm_lpss_is_updating() check may trigger because the resume triggered by the pm_runtime_get() call is not complete yet, so the ctrl register still reads all 1 / 0xffffffff. This commit fixes these issues by moving the initial pm_runtime_get() call for PWMs which are enabled at probe time to the pwm_lpss_probe() function; and by making get_state take a runtime-pm ref before reading the ctrl reg.

[PATCH] smb3: add indatalen that can be a non-zero value to calculation of credit charge in smb2 ioctl

by Namjae Jeon

Some of tests in xfstests failed with cifsd kernel server since commit e80ddeb2f70e. cifsd kernel server validates credit charge from client by calculating it base on max((InputCount + OutputCount) and (MaxInputResponse + MaxOutputResponse)) according to specification. MS-SMB2 specification describe credit charge calculation of smb2 ioctl : If Connection.SupportsMultiCredit is TRUE, the server MUST validate CreditCharge based on the maximum of (InputCount + OutputCount) and (MaxInputResponse + MaxOutputResponse), as specified in section 3.3.5.2.5. If the validation fails, it MUST fail the IOCTL request with STATUS_INVALID_PARAMETER. This patch add indatalen that can be a non-zero value to calculation of credit charge in SMB2_ioctl_init().

[7d2debdcdb3cb93c1e5e] [PATCH v2] proc: Use new_inode not new_inode_pseudo

by Frank Werner-Krippendorf

From: "Eric W. Biederman" <ebiederm(a)xmission.com> Recently syzbot reported that unmounting proc when there is an ongoing inotify watch on the root directory of proc could result in a use after free when the watch is removed after the unmount of proc when the watcher exits. Commit 69879c01a0c3 ("proc: Remove the now unnecessary internal mount of proc") made it easier to unmount proc and allowed syzbot to see the problem, but looking at the code it has been around for a long time. Looking at the code the fsnotify watch should have been removed by fsnotify_sb_delete in generic_shutdown_super. Unfortunately the inode was allocated with new_inode_pseudo instead of new_inode so the inode was not on the sb->s_inodes list. Which prevented fsnotify_unmount_inodes from finding the inode and removing the watch as well as made it so the "VFS: Busy inodes after unmount" warning could not find the inodes to warn about them. Make all of the inodes in proc visible to generic_shutdown_super, and fsnotify_sb_delete by using new_inode instead of new_inode_pseudo. The only functional difference is that new_inode places the inodes on the sb->s_inodes list. I wrote a small test program and I can verify that without changes it can trigger this issue, and by replacing new_inode_pseudo with new_inode the issues goes away.

[PATCH] ARM: tegra: Fix restoration of PLLM when exiting suspend

by Jon Hunter

The suspend entry and exit code for 32-bit Tegra devices assumes that the PLLM (which is used to provide the clock for external memory) is always enabled on entry to suspend. Hence, the current code always disables the PLLM on entry to suspend and re-enables the PLLM on exit from suspend. Since the introduction of the Tegra124 EMC driver by commit 73a7f0a90641 ("memory: tegra: Add EMC (external memory controller) driver"), which is used to scale the EMC frequency, PLLM may not be the current clock source for the EMC on entry to suspend and hence may not be enabled. Always enabling the PLLM on exit from suspend can cause the actual status on the PLL to be different from that reported by the common clock framework. On kernels prior to v4.5, the code to set the rate of the PLLM had a test to verify if the PLL was enabled and if the PLL was enabled, setting the rate would fail. Since commit 267b62a96951 ("clk: tegra: pll: Update PLLM handling") the test to see if PLLM is enabled was removed. With these earlier kernels, if the PLLM is disabled on entering suspend and the EMC driver attempts to set the parent of the EMC clock to the PLLM on exiting suspend, then the set rate for the PLLM will fail and in turn cause the resume to fail. We should not be re-enabling the PLLM on resume from suspend unless it was enabled on entry to suspend. Therefore, fix this by saving the state of PLLM on entry to suspend and only re-enable it, if it was already enabled.

[PATCH] crypto: algboss - don't wait during notifier callback

by Eric Biggers

From: Eric Biggers <ebiggers(a)google.com> When a crypto template needs to be instantiated, CRYPTO_MSG_ALG_REQUEST is sent to crypto_chain. cryptomgr_schedule_probe() handles this by starting a thread to instantiate the template, then waiting for this thread to complete via crypto_larval::completion. This can deadlock because instantiating the template may require loading modules, and this (apparently depending on userspace) may need to wait for the crc-t10dif module (lib/crc-t10dif.c) to be loaded. But crc-t10dif's module_init function uses crypto_register_notifier() and therefore takes crypto_chain.rwsem for write. That can't proceed until the notifier callback has finished, as it holds this semaphore for read. Fix this by removing the wait on crypto_larval::completion from within cryptomgr_schedule_probe(). It's actually unnecessary because crypto_alg_mod_lookup() calls crypto_larval_wait() itself after sending CRYPTO_MSG_ALG_REQUEST. This only actually became a problem in v4.20 due to commit b76377543b73 ("crc-t10dif: Pick better transform if one becomes available"), but the unnecessary wait was much older.

Suggest make 'user_access_begin()' do 'access_ok()' to stable kernel

by Miles Chen

Hi, I suggest to include the commit: 594cc251fdd0 make 'user_access_begin()' do 'access_ok()' for CVE-2018-20669. stable version to apply to: kernel-4.14.y and kernel-4.19.y. From the discussion below, I checked the latest kernel and found that we should also apply other 4 patches. (total 5 patches) https://lkml.org/lkml/2020/5/12/943 patch list: commit ab10ae1c3bef lib: Reduce user_access_begin() boundaries in strncpy_from_user() and strnlen_user() commit 6e693b3ffecb x86: uaccess: Inhibit speculation past access_ok() in user_access_begin() commit 9cb2feb4d21d arch/openrisc: Fix issues with access_ok() commit 94bd8a05cd4d Fix 'acccess_ok()' on alpha and SH commit 594cc251fdd0 make 'user_access_begin()' do 'access_ok()' Where only commit 6e693b3ffecb does not need backport modifications. I attach my backport patches in this email. I merged the patches with kernel-4.19.127 and kernel-4.14.183 without conflicts. Build with arm64 defconfig and bootup on arm64 QEMU environment. cheers, Miles

[patch 4/5] lib/lzo: fix ambiguous encoding bug in lzo-rle

by Andrew Morton

From: Dave Rodgman <dave.rodgman(a)arm.com> Subject: lib/lzo: fix ambiguous encoding bug in lzo-rle In some rare cases, for input data over 32 KB, lzo-rle could encode two different inputs to the same compressed representation, so that decompression is then ambiguous (i.e. data may be corrupted - although zram is not affected because it operates over 4 KB pages). This modifies the compressor without changing the decompressor or the bitstream format, such that: - there is no change to how data produced by the old compressor is decompressed - an old decompressor will correctly decode data from the updated compressor - performance and compression ratio are not affected - we avoid introducing a new bitstream format In testing over 12.8M real-world files totalling 903 GB, three files were affected by this bug. I also constructed 37M semi-random 64 KB files totalling 2.27 TB, and saw no affected files. Finally I tested over files constructed to contain each of the ~1024 possible bad input sequences; for all of these cases, updated lzo-rle worked correctly. There is no significant impact to performance or compression ratio.

[PATCH] lib/vdso: use CLOCK_REALTIME_COARSE for time()

by Mark Salyzyn

From: Chiawei Wang <chiaweiwang(a)google.com> CLOCK_REALTIME in vdso data won't be updated if __arch_use_vsyscall() returns false. It will let time() return an incorrect time value. Since time() is designed to return the seconds since the Epoch, using CLOCK_REALTIME_COARSE can still fulfill the request and never fails.

[PATCH v1 4/8] watchdog: f71808e_wdt: clear watchdog timeout occurred flag

by Ahmad Fatoum

The flag indicating a watchdog timeout having occurred normally persists till Power-On Reset of the Fintek Super I/O chip. The user can clear it by writing a `1' to the bit. The driver doesn't offer a restart method, so regular system reboot might not reset the Super I/O and if the watchdog isn't enabled, we won't touch the register containing the bit on the next boot. In this case all subsequent regular reboots will be wrongly flagged by the driver as being caused by the watchdog. Fix this by having the flag cleared after read. This is also done by other drivers like those for the i6300esb and mpc8xxx_wdt.

[PATCH v1 3/8] watchdog: f71808e_wdt: remove use of wrong watchdog_info option

by Ahmad Fatoum

The flags that should be or-ed into the watchdog_info.options by drivers all start with WDIOF_, e.g. WDIOF_SETTIMEOUT, which indicates that the driver's watchdog_ops has a usable set_timeout. WDIOC_SETTIMEOUT was used instead, which expands to 0xc0045706, which equals: WDIOF_FANFAULT | WDIOF_EXTERN1 | WDIOF_PRETIMEOUT | WDIOF_ALARMONLY | WDIOF_MAGICCLOSE | 0xc0045000 These were so far indicated to userspace on WDIOC_GETSUPPORT. As the driver has not yet been migrated to the new watchdog kernel API, the constant can just be dropped without substitute.

[git:media_tree/master] media: videobuf2-dma-contig: fix bad kfree in vb2_dma_contig_clear_max_seg_size

by Mauro Carvalho Chehab

This is an automatic generated email to let you know that the following patch were queued: Subject: media: videobuf2-dma-contig: fix bad kfree in vb2_dma_contig_clear_max_seg_size Author: Tomi Valkeinen <tomi.valkeinen(a)ti.com> Date: Wed May 27 10:23:34 2020 +0200 Commit 9495b7e92f716ab2bd6814fab5e97ab4a39adfdd ("driver core: platform: Initialize dma_parms for platform devices") in v5.7-rc5 causes vb2_dma_contig_clear_max_seg_size() to kfree memory that was not allocated by vb2_dma_contig_set_max_seg_size(). The assumption in vb2_dma_contig_set_max_seg_size() seems to be that dev->dma_parms is always NULL when the driver is probed, and the case where dev->dma_parms has bee initialized by someone else than the driver (by calling vb2_dma_contig_set_max_seg_size) will cause a failure. All the current users of these functions are platform devices, which now always have dma_parms set by the driver core. To fix the issue for v5.7, make vb2_dma_contig_set_max_seg_size() return an error if dma_parms is NULL to be on the safe side, and remove the kfree code from vb2_dma_contig_clear_max_seg_size().

[git:media_tree/master] media: cedrus: Program output format during each run

by Mauro Carvalho Chehab

This is an automatic generated email to let you know that the following patch were queued: Subject: media: cedrus: Program output format during each run Author: Samuel Holland <samuel(a)sholland.org> Date: Sat May 9 22:06:42 2020 +0200 Previously, the output format was programmed as part of the ioctl() handler. However, this has two problems: 1) If there are multiple active streams with different output formats, the hardware will use whichever format was set last for both streams. Similarly, an ioctl() done in an inactive context will wrongly affect other active contexts. 2) The registers are written while the device is not actively streaming. To enable runtime PM tied to the streaming state, all hardware access needs to be moved inside cedrus_device_run(). The call to cedrus_dst_format_set() is now placed just before the codec-specific callback that programs the hardware.

[tip: x86/urgent] x86/speculation: Avoid force-disabling IBPB based on STIBP and enhanced IBRS.

by tip-bot2 for Anthony Steinhauser

The following commit has been merged into the x86/urgent branch of tip: Commit-ID: 21998a351512eba4ed5969006f0c55882d995ada Gitweb: https://git.kernel.org/tip/21998a351512eba4ed5969006f0c55882d995ada Author: Anthony Steinhauser <asteinhauser(a)google.com> AuthorDate: Tue, 19 May 2020 06:40:42 -07:00 Committer: Thomas Gleixner <tglx(a)linutronix.de> CommitterDate: Tue, 09 Jun 2020 10:50:54 +02:00 x86/speculation: Avoid force-disabling IBPB based on STIBP and enhanced IBRS. When STIBP is unavailable or enhanced IBRS is available, Linux force-disables the IBPB mitigation of Spectre-BTB even when simultaneous multithreading is disabled. While attempts to enable IBPB using prctl(PR_SET_SPECULATION_CTRL, PR_SPEC_INDIRECT_BRANCH, ...) fail with EPERM, the seccomp syscall (or its prctl(PR_SET_SECCOMP, ...) equivalent) which are used e.g. by Chromium or OpenSSH succeed with no errors but the application remains silently vulnerable to cross-process Spectre v2 attacks (classical BTB poisoning). At the same time the SYSFS reporting (/sys/devices/system/cpu/vulnerabilities/spectre_v2) displays that IBPB is conditionally enabled when in fact it is unconditionally disabled. STIBP is useful only when SMT is enabled. When SMT is disabled and STIBP is unavailable, it makes no sense to force-disable also IBPB, because IBPB protects against cross-process Spectre-BTB attacks regardless of the SMT state. At the same time since missing STIBP was only observed on AMD CPUs, AMD does not recommend using STIBP, but recommends using IBPB, so disabling IBPB because of missing STIBP goes directly against AMD's advice: https://developer.amd.com/wp-content/resources/Architecture_Guidelines_Upda… Similarly, enhanced IBRS is designed to protect cross-core BTB poisoning and BTB-poisoning attacks from user space against kernel (and BTB-poisoning attacks from guest against hypervisor), it is not designed to prevent cross-process (or cross-VM) BTB poisoning between processes (or VMs) running on the same core. Therefore, even with enhanced IBRS it is necessary to flush the BTB during context-switches, so there is no reason to force disable IBPB when enhanced IBRS is available. Enable the prctl control of IBPB even when STIBP is unavailable or enhanced IBRS is available.

[PATCH] spi: spi-fsl-dspi: Free DMA memory with matching function

[PATCH v2] ext4: avoid utf8_strncasecmp() with unstable name

by Eric Biggers

From: Eric Biggers <ebiggers(a)google.com> If the dentry name passed to ->d_compare() fits in dentry::d_iname, then it may be concurrently modified by a rename. This can cause undefined behavior (possibly out-of-bounds memory accesses or crashes) in utf8_strncasecmp(), since fs/unicode/ isn't written to handle strings that may be concurrently modified. Fix this by first copying the filename to a stack buffer if needed. This way we get a stable snapshot of the filename.

Re: Patch "crypto: talitos - fix ECB and CBC algs ivsize" has been added to the 4.9-stable tree

As far as I can see, the faulty commit e1de42fdfc6a ("crypto: talitos - fix ECB algs ivsize") only removed .ivsize = AES_BLOCK_SIZE at a wrong place. The other changes (removal of .ivsize = DES_BLOCK_SIZE and .ivsize = DES3_EDE_BLOCK_SIZE) are not from the faulty patch.

[PATCH v4.19.y 0/2] btrfs: Fix for CVE-2019-18885

by Vikash Bansal

CVE Description: NVD Site Link: https://nvd.nist.gov/vuln/detail?vulnId=CVE-2019-18885 It was discovered that the btrfs file system in the Linux kernel did not properly validate metadata, leading to a NULL pointer dereference. An attacker could use this to specially craft a file system image that, when mounted, could cause a denial of service (system crash). [PATCH v4.19.y 1/2]: Backporting of upsream commit 09ba3bc9dd15: btrfs: merge btrfs_find_device and find_device [PATCH v4.19.y 2/2]: Backporting of upstream commit 62fdaa52a3d0: btrfs: Detect unbalanced tree with empty leaf before crashing On NVD site link of "commit 09ba3bc9dd150457c506e4661380a6183af651c1" was given as the fix for this CVE. But the issue was still reproducible. So had to apply patch "Commit 62fdaa52a3d00a875da771719b6dc537ca79fce1" to fix the issue.

[PATCH v2] serial: imx: Fix handling of TC irq in combination with DMA

by Schrempf Frieder

From: Uwe Kleine-König <u.kleine-koenig(a)pengutronix.de> commit 1866541492641c02874bf51f9d8712b5510f2c64 upstream When using RS485 half duplex the Transmitter Complete irq is needed to determine the moment when the transmitter can be disabled. When using DMA this irq must only be enabled when DMA has completed to transfer all data. Otherwise the CPU might busily trigger this irq which is not properly handled and so the also pending irq for the DMA transfer cannot trigger.

[PATCH STABLE v4.4+] pwm: fsl-ftm: Use flat regmap cache

by Krzysztof Kozlowski

From: Stefan Agner <stefan(a)agner.ch> commit ad06fdeeef1cbadf86ebbe510e8079abada8b44e upstream. Use flat regmap cache to avoid lockdep warning at probe: [ 0.697285] WARNING: CPU: 0 PID: 1 at kernel/locking/lockdep.c:2755 lockdep_trace_alloc+0x15c/0x160() [ 0.697449] DEBUG_LOCKS_WARN_ON(irqs_disabled_flags(flags)) The RB-tree regmap cache needs to allocate new space on first writes. However, allocations in an atomic context (e.g. when a spinlock is held) are not allowed. The function regmap_write calls map->lock, which acquires a spinlock in the fast_io case. Since the pwm-fsl-ftm driver uses MMIO, the regmap bus of type regmap_mmio is being used which has fast_io set to true. The MMIO space of the pwm-fsl-ftm driver is reasonable condense, hence using the much faster flat regmap cache is anyway the better choice.

[PATCH] bpf: Support llvm-objcopy for vmlinux BTF

by Maria Teguiani

From: Fangrui Song <maskray(a)google.com> Simplify gen_btf logic to make it work with llvm-objcopy. The existing 'file format' and 'architecture' parsing logic is brittle and does not work with llvm-objcopy/llvm-objdump. 'file format' output of llvm-objdump>=11 will match GNU objdump, but 'architecture' (bfdarch) may not. .BTF in .tmp_vmlinux.btf is non-SHF_ALLOC. Add the SHF_ALLOC flag because it is part of vmlinux image used for introspection. C code can reference the section via linker script defined __start_BTF and __stop_BTF. This fixes a small problem that previous .BTF had the SHF_WRITE flag (objcopy -I binary -O elf* synthesized .data). Additionally, `objcopy -I binary` synthesized symbols _binary__btf_vmlinux_bin_start and _binary__btf_vmlinux_bin_stop (not used elsewhere) are replaced with more commonplace __start_BTF and __stop_BTF. Add 2>/dev/null because GNU objcopy (but not llvm-objcopy) warns "empty loadable segment detected at vaddr=0xffffffff81000000, is this intentional?" We use a dd command to change the e_type field in the ELF header from ET_EXEC to ET_REL so that lld will accept .btf.vmlinux.bin.o. Accepting ET_EXEC as an input file is an extremely rare GNU ld feature that lld does not intend to support, because this is error-prone. The output section description .BTF in include/asm-generic/vmlinux.lds.h avoids potential subtle orphan section placement issues and suppresses --orphan-handling=warn warnings.

[PATCH 10/11] KVM: arm64: Synchronize sysreg state on injecting an AArch32 exception

by Marc Zyngier

On a VHE system, the EL1 state is left in the CPU most of the time, and only syncronized back to memory when vcpu_put() is called (most of the time on preemption). Which means that when injecting an exception, we'd better have a way to either: (1) write directly to the EL1 sysregs (2) synchronize the state back to memory, and do the changes there For an AArch64, we already do (1), so we are safe. Unfortunately, doing the same thing for AArch32 would be pretty invasive. Instead, we can easily implement (2) by calling the put/load architectural backends, and keep preemption disabled. We can then reload the state back into EL1.

[PATCH 09/11] KVM: arm64: Make vcpu_cp1x() work on Big Endian hosts

by Marc Zyngier

AArch32 CP1x registers are overlayed on their AArch64 counterparts in the vcpu struct. This leads to an interesting problem as they are stored in their CPU-local format, and thus a CP1x register doesn't "hit" the lower 32bit portion of the AArch64 register on a BE host. To workaround this unfortunate situation, introduce a bias trick in the vcpu_cp1x() accessors which picks the correct half of the 64bit register.

[PATCH 05/11] KVM: arm64: Save the host's PtrAuth keys in non-preemptible context

by Marc Zyngier

When using the PtrAuth feature in a guest, we need to save the host's keys before allowing the guest to program them. For that, we dump them in a per-CPU data structure (the so called host context). But both call sites that do this are in preemptible context, which may end up in disaster should the vcpu thread get preempted before reentering the guest. Instead, save the keys eagerly on each vcpu_load(). This has an increased overhead, but is at least safe.

[PATCH 02/11] KVM: arm64: Stop writing aarch32's CSSELR into ACTLR

by Marc Zyngier

From: James Morse <james.morse(a)arm.com> aarch32 has pairs of registers to access the high and low parts of 64bit registers. KVM has a union of 64bit sys_regs[] and 32bit copro[]. The 32bit accessors read the high or low part of the 64bit sys_reg[] value through the union. Both sys_reg_descs[] and cp15_regs[] list access_csselr() as the accessor for CSSELR{,_EL1}. access_csselr() is only aware of the 64bit sys_regs[], and expects r->reg to be 'CSSELR_EL1' in the enum, index 2 of the 64bit array. cp15_regs[] uses the 32bit copro[] alias of sys_regs[]. Here CSSELR is c0_CSSELR which is the same location in sys_reg[]. r->reg is 'c0_CSSELR', index 4 in the 32bit array. access_csselr() uses the 32bit r->reg value to access the 64bit array, so reads and write the wrong value. sys_regs[4], is ACTLR_EL1, which is subsequently save/restored when we enter the guest. ACTLR_EL1 is supposed to be read-only for the guest. This register only affects execution at EL1, and the host's value is restored before we return to host EL1. Convert the 32bit register index back to the 64bit version.

[PATCH for 4.4 and 4.9] scsi: return correct blkprep status code in case scsi_init_io() fails.

by Nobuhiro Iwamatsu

From: Johannes Thumshirn <jthumshirn(a)suse.de> commit e7661a8e5ce10b5321882d0bbaf3f81070903319 upstream. When instrumenting the SCSI layer to run into the !blk_rq_nr_phys_segments(rq) case the following warning emitted from the block layer: blk_peek_request: bad return=-22 This happens because since commit fd3fc0b4d730 ("scsi: don't BUG_ON() empty DMA transfers") we return the wrong error value from scsi_prep_fn() back to the block layer.
