FAILED: patch "[PATCH] dm integrity: fix a deadlock due to offloading to an" failed to apply to 4.19-stable tree

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 53770f0ec5fd417429775ba006bc4abe14002335 Mon Sep 17 00:00:00 2001 From: Mikulas Patocka <mpatocka(a)redhat.com> Date: Mon, 17 Feb 2020 07:43:03 -0500 Subject: [PATCH] dm integrity: fix a deadlock due to offloading to an incorrect workqueue If we need to perform synchronous I/O in dm_integrity_map_continue(), we must make sure that we are not in the map function - in order to avoid the deadlock due to bio queuing in generic_make_request. To avoid the deadlock, we offload the request to metadata_wq. However, metadata_wq also processes metadata updates for write requests. If there are too many requests that get offloaded to metadata_wq at the beginning of dm_integrity_map_continue, the workqueue metadata_wq becomes clogged and the system is incapable of processing any metadata updates. This causes a deadlock because all the requests that need to do metadata updates wait for metadata_wq to proceed and metadata_wq waits inside wait_and_add_new_range until some existing request releases its range lock (which doesn't happen because the range lock is released after metadata update). In order to fix the deadlock, we create a new workqueue offload_wq and offload requests to it - so that processing of offload_wq is independent from processing of metadata_wq.

The work entry on the workqueue is executed even after the bitmap was freed. The problem is that cancel_delayed_work doesn't wait for the running work item to finish, so the work item can continue running and re-submitting itself even after cache_postsuspend. In order to make sure that the work item won't be running, we must use cancel_delayed_work_sync. Also, change flush_workqueue to drain_workqueue, so that if some work item submits itself or another work item, we are properly waiting for both of them.

There is a BUG_ON inside the mmu_notifier to guard against this. Normally creating a umem is done against current which implicitly holds the mmget(), however an implicit ODP child is created from a pagefault work queue and is not guaranteed to have a mmget(). Call mmget() around this registration and abort faulting if the MM has gone to exit_mmap(). Before the patch below the notifier was registered when the implicit ODP parent was created, so there was no chance to register a notifier outside of current.

This is hardly noticeable because the only programming we do is enabling SSC or not, which is not really causing an observable functional change. Correct that mistake by passing down the struct brcm_sata_port structure down to the brcm_sata_mdio_wr() and brcm_sata_mdio_rd() functions and do the proper offsetting for 28nm, respectively 40nm platforms from there. This means that brcm_sata_pcb_base() is now useless and is therefore removed.

This is hardly noticeable because the only programming we do is enabling SSC or not, which is not really causing an observable functional change. Correct that mistake by passing down the struct brcm_sata_port structure down to the brcm_sata_mdio_wr() and brcm_sata_mdio_rd() functions and do the proper offsetting for 28nm, respectively 40nm platforms from there. This means that brcm_sata_pcb_base() is now useless and is therefore removed.

This is hardly noticeable because the only programming we do is enabling SSC or not, which is not really causing an observable functional change. Correct that mistake by passing down the struct brcm_sata_port structure down to the brcm_sata_mdio_wr() and brcm_sata_mdio_rd() functions and do the proper offsetting for 28nm, respectively 40nm platforms from there. This means that brcm_sata_pcb_base() is now useless and is therefore removed.

This is hardly noticeable because the only programming we do is enabling SSC or not, which is not really causing an observable functional change. Correct that mistake by passing down the struct brcm_sata_port structure down to the brcm_sata_mdio_wr() and brcm_sata_mdio_rd() functions and do the proper offsetting for 28nm, respectively 40nm platforms from there. This means that brcm_sata_pcb_base() is now useless and is therefore removed.

This is hardly noticeable because the only programming we do is enabling SSC or not, which is not really causing an observable functional change. Correct that mistake by passing down the struct brcm_sata_port structure down to the brcm_sata_mdio_wr() and brcm_sata_mdio_rd() functions and do the proper offsetting for 28nm, respectively 40nm platforms from there. This means that brcm_sata_pcb_base() is now useless and is therefore removed.

[PATCH] i2c: designware-pci: Fix BUG_ON during device removal

by Jarkko Nikula

Function i2c_dw_pci_remove() -> pci_free_irq_vectors() -> pci_disable_msi() -> free_msi_irqs() will throw a BUG_ON() for MSI enabled device since the driver has not released the requested IRQ before calling the pci_free_irq_vectors(). Here driver requests an IRQ using devm_request_irq() but automatic release happens only after remove callback. Fix this by explicitly freeing the IRQ before calling pci_free_irq_vectors().

[Patch v2] media: ti-vpe: cal: fix a kernel oops when unloading module

by Benoit Parrot

After the switch to use v4l2_async_notifier_add_subdev() and v4l2_async_notifier_cleanup(), unloading the ti_cal module would casue a kernel oops. This was root cause to the fact that v4l2_async_notifier_cleanup() tries to kfree the asd pointer passed into v4l2_async_notifier_add_subdev(). In our case the asd reference was from a statically allocated struct. So in effect v4l2_async_notifier_cleanup() was trying to free a pointer that was not kalloc. So here we switch to using a kzalloc struct instead of a static one. To acheive this we re-order some of the calls to prevent asd allocation from leaking.

In flush_coherent_icache() we implement an optimisation for CPUs where we know we don't actually have to flush the whole range, we just need to do a single icbi. However we still execute the icbi on the user address of the start of the range we're flushing. On CPUs that also implement KUAP (Power9) that leads to the spurious fault above. We should be able to pass any address, including a kernel address, to the icbi on these CPUs, which would avoid any interaction with KUAP. But I don't want to make that change in a bug fix, just in case it surfaces some strange behaviour on some CPU. So for now just disable KUAP around the icbi. Note the icbi is treated as a load, so we allow read access, not write as you'd expect.

Aborted tests ------------- Tests that didn't complete running successfully are marked with ⚡⚡⚡. If this was caused by an infrastructure issue, we try to mark that explicitly in the report. Waived tests ------------ If the test run included waived tests, they are marked with 🚧. Such tests are executed but their results are not taken into account. Tests are waived when their results are not reliable enough, e.g. when they're just introduced or are being fixed. Testing timeout --------------- We aim to provide a report within reasonable timeframe. Tests that haven't finished running yet are marked with ⏱.

[PATCH 2/2] iommu/vt-d: dmar_parse_one_rmrr: replace WARN_TAINT with pr_warn + add_taint

by Hans de Goede

Quoting from the comment describing the WARN functions in include/asm-generic/bug.h: * WARN(), WARN_ON(), WARN_ON_ONCE, and so on can be used to report * significant kernel issues that need prompt attention if they should ever * appear at runtime. * * Do not use these macros when checking for invalid external inputs The (buggy) firmware tables which the dmar code was calling WARN_TAINT for really are invalid external inputs. They are not under the kernel's control and the issues in them cannot be fixed by a kernel update. So logging a backtrace, which invites bug reports to be filed about this, is not helpful. Some distros, e.g. Fedora, have tools watching for the kernel backtraces logged by the WARN macros and offer the user an option to file a bug for this when these are encountered. The WARN_TAINT in dmar_parse_one_rmrr + another iommu WARN_TAINT, addressed in another patch, have lead to over a 100 bugs being filed this way. This commit replaces the WARN_TAINT("...") call, with a pr_warn(FW_BUG "...") + add_taint(TAINT_FIRMWARE_WORKAROUND, ...) call avoiding the backtrace and thus also avoiding bug-reports being filed about this against the kernel.

FAILED: patch "[PATCH] mm: fix possible PMD dirty bit lost in" 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 8a8683ad9ba48b4b52a57f013513d1635c1ca5c4 Mon Sep 17 00:00:00 2001 From: Huang Ying <ying.huang(a)intel.com> Date: Thu, 5 Mar 2020 22:28:29 -0800 Subject: [PATCH] mm: fix possible PMD dirty bit lost in set_pmd_migration_entry() In set_pmd_migration_entry(), pmdp_invalidate() is used to change PMD atomically. But the PMD is read before that with an ordinary memory reading. If the THP (transparent huge page) is written between the PMD reading and pmdp_invalidate(), the PMD dirty bit may be lost, and cause data corruption. The race window is quite small, but still possible in theory, so need to be fixed. The race is fixed via using the return value of pmdp_invalidate() to get the original content of PMD, which is a read/modify/write atomic operation. So no THP writing can occur in between. The race has been introduced when the THP migration support is added in the commit 616b8371539a ("mm: thp: enable thp migration in generic path"). But this fix depends on the commit d52605d7cb30 ("mm: do not lose dirty and accessed bits in pmdp_invalidate()"). So it's easy to be backported after v4.16.

[for-linus][PATCH 3/4] ktest: Add timeout for ssh sync testing

by Steven Rostedt

From: "Steven Rostedt (VMware)" <rostedt(a)goodmis.org> Before rebooting the box, a "ssh sync" is called to the test machine to see if it is alive or not. But if the test machine is in a partial state, that ssh may never actually finish, and the ktest test hangs. Add a 10 second timeout to the sync test, which will fail after 10 seconds and then cause the test to reboot the test machine.

The work entry on the workqueue is executed even after the bitmap was freed. The problem is that cancel_delayed_work doesn't wait for the running work item to finish, so the work item can continue running and re-submitting itself even after cache_postsuspend. In order to make sure that the work item won't be running, we must use cancel_delayed_work_sync. Also, change flush_workqueue to drain_workqueue, so that if some work item submits itself or another work item, we are properly waiting for both of them.

To avoid the deadlock, we offload the request to metadata_wq. However, metadata_wq also processes metadata updates for write requests. If there are too many requests that get offloaded to metadata_wq at the beginning of dm_integrity_map_continue, the workqueue metadata_wq becomes clogged and the system is incapable of processing any metadata updates. This causes a deadlock because all the requests that need to do metadata updates wait for metadata_wq to proceed and metadata_wq waits inside wait_and_add_new_range until some existing request releases its range lock (which doesn't happen because the range lock is released after metadata update). In order to fix the deadlock, we create a new workqueue offload_wq and offload requests to it - so that processing of offload_wq is independent from processing of metadata_wq.

[PATCH v4] pinctrl: qcom: Assign irq_eoi conditionally

by Linus Walleij

The hierarchical parts of MSM pinctrl/GPIO is only used when the device tree has a "wakeup-parent" as a phandle, but the .irq_eoi is anyway assigned leading to semantic problems on elder Qualcomm chipsets. When the drivers/mfd/qcom-pm8xxx.c driver calls chained_irq_exit() that call will in turn call chip->irq_eoi() which is set to irq_chip_eoi_parent() by default on a hierachical IRQ chip, and the parent is pinctrl-msm.c so that will in turn unconditionally call irq_chip_eoi_parent() again, but its parent is invalid so we get the following crash: Unnable to handle kernel NULL pointer dereference at virtual address 00000010 pgd = (ptrval) [00000010] *pgd=00000000 Internal error: Oops: 5 [#1] PREEMPT SMP ARM (...)

[PATCH v2] net: stmmac: dwmac1000: Disable ACS if enhanced descs are not used

by Remi Pommarel

ACS (auto PAD/FCS stripping) removes FCS off 802.3 packets (LLC) so that there is no need to manually strip it for such packets. The enhanced DMA descriptors allow to flag LLC packets so that the receiving callback can use that to strip FCS manually or not. On the other hand, normal descriptors do not support that. Thus in order to not truncate LLC packet ACS should be disabled when using normal DMA descriptors. Fixes: 47dd7a540b8a0 ("net: add support for STMicroelectronics Ethernet controllers.")

[PATCH v2] pid: Fix error return value in some cases

by minyard＠acm.org

From: Corey Minyard <cminyard(a)mvista.com> Recent changes to alloc_pid() allow the pid number to be specified on the command line. If set_tid_size is set, then the code scanning the levels will hard-set retval to -EPERM, overriding it's previous -ENOMEM value. After the code scanning the levels, there are error returns that do not set retval, assuming it is still set to -ENOMEM. So set retval back to -ENOMEM after scanning the levels. Fixes: 49cb2fc42ce4 "fork: extend clone3() to support setting a PID" Signed-off-by: Corey Minyard <cminyard(a)mvista.com> Cc: <stable(a)vger.kernel.org> # 5.5 Cc: Adrian Reber <areber(a)redhat.com> Cc: Christian Brauner <christian.brauner(a)ubuntu.com> Cc: Oleg Nesterov <oleg(a)redhat.com> Cc: Dmitry Safonov <0x7f454c46(a)gmail.com> Cc: Andrei Vagin <avagin(a)gmail.com> --- Changes from v1: Just set retval to -ENOMEM before the gotos that would use it. I do think that the second instance: if (!(ns->pid_allocated & PIDNS_ADDING)) goto out_unlock; is returning the wrong error value, but that's probably not a big deal, and if it was fixed would probably need to be a separate change. In the first instance, the error return values are almost all -ENOMEM, anyway. kernel/pid.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/kernel/pid.c b/kernel/pid.c index 0f4ecb57214c..19645b25b77c 100644 --- a/kernel/pid.c +++ b/kernel/pid.c @@ -247,6 +247,8 @@ struct pid *alloc_pid(struct pid_namespace *ns, pid_t *set_tid, tmp = tmp->parent; } + retval = -ENOMEM; + if (unlikely(is_child_reaper(pid))) { if (pid_ns_prepare_proc(ns)) goto out_free; -- 2.17.1

[tip: efi/urgent] efi: Fix a race and a buffer overflow while reading efivars via sysfs

by tip-bot2 for Vladis Dronov

The following commit has been merged into the efi/urgent branch of tip: Commit-ID: 286d3250c9d6437340203fb64938bea344729a0e Gitweb: https://git.kernel.org/tip/286d3250c9d6437340203fb64938bea344729a0e Author: Vladis Dronov <vdronov(a)redhat.com> AuthorDate: Sun, 08 Mar 2020 09:08:54 +01:00 Committer: Ingo Molnar <mingo(a)kernel.org> CommitterDate: Sun, 08 Mar 2020 09:56:34 +01:00 efi: Fix a race and a buffer overflow while reading efivars via sysfs There is a race and a buffer overflow corrupting a kernel memory while reading an EFI variable with a size more than 1024 bytes via the older sysfs method. This happens because accessing struct efi_variable in efivar_{attr,size,data}_read() and friends is not protected from a concurrent access leading to a kernel memory corruption and, at best, to a crash. The race scenario is the following: CPU0: CPU1: efivar_attr_read() var->DataSize = 1024; efivar_entry_get(... &var->DataSize) down_interruptible(&efivars_lock) efivar_attr_read() // same EFI var var->DataSize = 1024; efivar_entry_get(... &var->DataSize) down_interruptible(&efivars_lock) virt_efi_get_variable() // returns EFI_BUFFER_TOO_SMALL but // var->DataSize is set to a real // var size more than 1024 bytes up(&efivars_lock) virt_efi_get_variable() // called with var->DataSize set // to a real var size, returns // successfully and overwrites // a 1024-bytes kernel buffer up(&efivars_lock) This can be reproduced by concurrent reading of an EFI variable which size is more than 1024 bytes: ts# for cpu in $(seq 0 $(nproc --ignore=1)); do ( taskset -c $cpu \ cat /sys/firmware/efi/vars/KEKDefault*/size & ) ; done Fix this by using a local variable for a var's data buffer size so it does not get overwritten.

[PATCH] power: supply: axp288_charger: Add special handling for HP Pavilion x2 10

by Hans de Goede

Some HP Pavilion x2 10 models use an AXP288 for charging and fuel-gauge. We use a native power_supply / PMIC driver in this case, because on most models with an AXP288 the ACPI AC / Battery code is either completely missing or relies on custom / proprietary ACPI OpRegions which Linux does not implement. The native drivers mostly work fine, but there are 2 problems: 1. These model uses a Type-C connector for charging which the AXP288 does not support. As long as a Type-A charger (which uses the USB data pins for charger type detection) is used everything is fine. But if a Type-C charger is used (such as the charger shipped with the device) then the charger is not recognized. So we end up slowly discharging the device even though a charger is connected, because we are limiting the current from the charger to 500mA. To make things worse this happens with the device's official charger. Looking at the ACPI tables HP has "solved" the problem of the AXP288 not being able to recognize Type-C chargers by simply always programming the input-current-limit at 3000mA and relying on a Vhold setting of 4.7V (normally 4.4V) to limit the current intake if the charger cannot handle this. 2. If no charger is connected when the machine boots then it boots with the vbus-path disabled. On other devices this is done when a 5V boost converter is active to avoid the PMIC trying to charge from the 5V boost output. This is done when an OTG host cable is inserted and the ID pin on the micro-B receptacle is pulled low, the ID pin has an ACPI event handler associated with it which re-enables the vbus-path when the ID pin is pulled high when the OTG cable is removed. The Type-C connector has no ID pin, there is no ID pin handler and there appears to be no 5V boost converter, so we end up not charging because the vbus-path is disabled, until we unplug the charger which automatically clears the vbus-path disable bit and then on the second plug-in of the adapter we start charging. The HP Pavilion x2 10 models with an AXP288 do have mostly working ACPI AC / Battery code which does not rely on custom / proprietary ACPI OpRegions. So one possible solution would be to blacklist the AXP288 native power_supply drivers and add the HP Pavilion x2 10 with AXP288 DMI ids to the list of devices which should use the ACPI AC / Battery code even though they have an AXP288 PMIC. This would require changes to 4 files: drivers/acpi/ac.c, drivers/power/supply/axp288_charger.c, drivers/acpi/battery.c and drivers/power/supply/axp288_fuel_gauge.c. Beside needing adding the same DMI matches to 4 different files, this approach also triggers problem 2. from above, but then when suspended, during suspend the machine will not wakeup because the vbus path is disabled by the AML code when not charging, so the Vbus low-to-high IRQ is not triggered, the CPU never wakes up and the device does not charge even though the user likely things it is charging, esp. since the charge status LED is directly coupled to an adapter being plugged in and does not reflect actual charging. This could be worked by enabling vbus-path explicitly from say the axp288_charger driver's suspend handler. So neither situation is ideal, in both cased we need to explicitly enable the vbus-path to work around different variants of problem 2 above, this requires a quirk in the axp288_charger code. If we go the route of using the ACPI AC / Battery drivers then we need modifications to 3 other drivers; and we need to partially disable the axp288_charger code, while at the same time keeping it around to enable vbus-path on suspend. OTOH we can copy the hardcoding of 3A input-current-limit (we never touch Vhold, so that would stay at 4.7V) to the axp288_charger code, which needs changes regardless, then we concentrate all special handling of this interesting device model in the axp288_charger code. That is what this commit does.

[PATCH 02/17] drm/i915/execlists: Enable timeslice on partial virtual engine dequeue

by Chris Wilson

If we stop filling the ELSP due to an incompatible virtual engine request, check if we should enable the timeslice on behalf of the queue. This fixes the case where we are inspecting the last->next element when we know that the last element is the last request in the execution queue, and so decided we did not need to enable timeslicing despite the intent to do so!

[PATCH] pinctrl: qcom: Guard irq_eoi()

by Linus Walleij

In the commit setting up the qcom/msm pin controller to be hierarchical some callbacks were careful to check that d->parent_data on irq_data was valid before calling the parent function, however irq_chip_eoi_parent() was called unconditionally which doesn't work with elder Qualcomm platforms such as APQ8060. When the drivers/mfd/qcom-pm8xxx.c driver calls chained_irq_exit() that call will in turn call chip->irq_eoi() which is set to irq_chip_eoi_parent() by default on a hierachical IRQ chip, and the parent is pinctrl-msm.c so that will in turn unconditionally call irq_chip_eoi_parent() again, but its parent is invalid so we get the following crash: Unnable to handle kernel NULL pointer dereference at virtual address 00000010 pgd = (ptrval) [00000010] *pgd=00000000 Internal error: Oops: 5 [#1] PREEMPT SMP ARM (...)

[PATCH] x86/kprobes: Prohibit probing on rcu_nmi_exit() and ist_exit()

by Masami Hiramatsu

Prohibit probing on rcu_nmi_exit() and ist_exit() which are called from do_int3()'s kprobe path after kprobe_int3_handler(). The commit c13324a505c7 ("x86/kprobes: Prohibit probing on functions before kprobe_int3_handler()") tried to fix similar issue, but it only marks the functions before kprobe_int3_handler() in do_int3(). If we put a kprobe on rcu_nmi_exit() or ist_exit(), the kprobes will detect reentrance. However, it only skips the kprobe handler, exits from do_int3() and hits ist_exit() and rcu_nmi_exit() again. Thus, it causes another int3 exception and finally we will get the kernel panic with "Unrecoverable kprobe detected." error message. This is reproducible by the following commands. / # echo 0 > /proc/sys/debug/kprobes-optimization / # echo p vfs_read > /sys/kernel/debug/tracing/kprobe_events / # echo p rcu_nmi_exit >> /sys/kernel/debug/tracing/kprobe_events / # echo 1 > /sys/kernel/debug/tracing/events/kprobes/enable Fixes: c13324a505c7 ("x86/kprobes: Prohibit probing on functions before kprobe_int3_handler()") Signed-off-by: Masami Hiramatsu <mhiramat(a)kernel.org> Cc: stable(a)vger.kernel.org --- arch/x86/kernel/traps.c | 1 + kernel/rcu/tree.c | 1 + 2 files changed, 2 insertions(+) diff --git a/arch/x86/kernel/traps.c b/arch/x86/kernel/traps.c index 6ef00eb6fbb9..c63fb7697794 100644 --- a/arch/x86/kernel/traps.c +++ b/arch/x86/kernel/traps.c @@ -115,6 +115,7 @@ void ist_exit(struct pt_regs *regs) if (!user_mode(regs)) rcu_nmi_exit(); } +NOKPROBE_SYMBOL(ist_exit); /** * ist_begin_non_atomic() - begin a non-atomic section in an IST exception diff --git a/kernel/rcu/tree.c b/kernel/rcu/tree.c index d91c9156fab2..c49ea0e919f9 100644 --- a/kernel/rcu/tree.c +++ b/kernel/rcu/tree.c @@ -670,6 +670,7 @@ void rcu_nmi_exit(void) { rcu_nmi_exit_common(false); } +NOKPROBE_SYMBOL(rcu_nmi_exit); /** * rcu_irq_exit - inform RCU that current CPU is exiting irq towards idle

[merged] mm-hotplug-fix-page-online-with-debug_pagealloc-compiled-but-not-enabled.patch removed from -mm tree

by akpm＠linux-foundation.org

The patch titled Subject: mm, hotplug: fix page online with DEBUG_PAGEALLOC compiled but not enabled has been removed from the -mm tree. Its filename was mm-hotplug-fix-page-online-with-debug_pagealloc-compiled-but-not-enabled.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Vlastimil Babka <vbabka(a)suse.cz> Subject: mm, hotplug: fix page online with DEBUG_PAGEALLOC compiled but not enabled Commit cd02cf1aceea ("mm/hotplug: fix an imbalance with DEBUG_PAGEALLOC") fixed memory hotplug with debug_pagealloc enabled, where onlining a page goes through page freeing, which removes the direct mapping. Some arches don't like when the page is not mapped in the first place, so generic_online_page() maps it first. This is somewhat wasteful, but better than special casing page freeing fast paths. The commit however missed that DEBUG_PAGEALLOC configured doesn't mean it's actually enabled.

[merged] mm-fix-possible-pmd-dirty-bit-lost-in-set_pmd_migration_entry.patch removed from -mm tree

by akpm＠linux-foundation.org

The patch titled Subject: mm: fix possible PMD dirty bit lost in set_pmd_migration_entry() has been removed from the -mm tree. Its filename was mm-fix-possible-pmd-dirty-bit-lost-in-set_pmd_migration_entry.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Huang Ying <ying.huang(a)intel.com> Subject: mm: fix possible PMD dirty bit lost in set_pmd_migration_entry() In set_pmd_migration_entry(), pmdp_invalidate() is used to change PMD atomically. But the PMD is read before that with an ordinary memory reading. If the THP (transparent huge page) is written between the PMD reading and pmdp_invalidate(), the PMD dirty bit may be lost, and cause data corruption. The race window is quite small, but still possible in theory, so need to be fixed. The race is fixed via using the return value of pmdp_invalidate() to get the original content of PMD, which is a read/modify/write atomic operation. So no THP writing can occur in between. The race has been introduced when the THP migration support is added in the commit 616b8371539a ("mm: thp: enable thp migration in generic path"). But this fix depends on the commit d52605d7cb30 ("mm: do not lose dirty and accessed bits in pmdp_invalidate()"). So it's easy to be backported after v4.16. But the race window is really small, so it may be fine not to backport the fix at all.

Its filename was mm-numa-fix-bad-pmd-by-atomically-check-for-pmd_trans_huge-when-marking-page-tables-prot_numa.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Mel Gorman <mgorman(a)techsingularity.net> Subject: mm, numa: fix bad pmd by atomically check for pmd_trans_huge when marking page tables prot_numa : A user reported a bug against a distribution kernel while running a : proprietary workload described as "memory intensive that is not swapping" : that is expected to apply to mainline kernels. The workload is : read/write/modifying ranges of memory and checking the contents. They : reported that within a few hours that a bad PMD would be reported followed : by a memory corruption where expected data was all zeros. A partial : report of the bad PMD looked like : : [ 5195.338482] ../mm/pgtable-generic.c:33: bad pmd ffff8888157ba008(000002e0396009e2) : [ 5195.341184] ------------[ cut here ]------------ : [ 5195.356880] kernel BUG at ../mm/pgtable-generic.c:35! : .... : [ 5195.410033] Call Trace: : [ 5195.410471] [<ffffffff811bc75d>] change_protection_range+0x7dd/0x930 : [ 5195.410716] [<ffffffff811d4be8>] change_prot_numa+0x18/0x30 : [ 5195.410918] [<ffffffff810adefe>] task_numa_work+0x1fe/0x310 : [ 5195.411200] [<ffffffff81098322>] task_work_run+0x72/0x90 : [ 5195.411246] [<ffffffff81077139>] exit_to_usermode_loop+0x91/0xc2 : [ 5195.411494] [<ffffffff81003a51>] prepare_exit_to_usermode+0x31/0x40 : [ 5195.411739] [<ffffffff815e56af>] retint_user+0x8/0x10 : : Decoding revealed that the PMD was a valid prot_numa PMD and the bad PMD : was a false detection. The bug does not trigger if automatic NUMA : balancing or transparent huge pages is disabled. : : The bug is due a race in change_pmd_range between a pmd_trans_huge and : pmd_nond_or_clear_bad check without any locks held. During the : pmd_trans_huge check, a parallel protection update under lock can have : cleared the PMD and filled it with a prot_numa entry between the transhuge : check and the pmd_none_or_clear_bad check. : : While this could be fixed with heavy locking, it's only necessary to make : a copy of the PMD on the stack during change_pmd_range and avoid races. A : new helper is created for this as the check if quite subtle and the : existing similar helpful is not suitable. This passed 154 hours of : testing (usually triggers between 20 minutes and 24 hours) without : detecting bad PMDs or corruption. A basic test of an autonuma-intensive : workload showed no significant change in behaviour. Although Mel withdrew the patch on the face of LKML comment https://lkml.org/lkml/2017/4/10/922 the race window aforementioned is still open, and we have reports of Linpack test reporting bad residuals after the bad PMD warning is observed. In addition to that, bad rss-counter and non-zero pgtables assertions are triggered on mm teardown for the task hitting the bad PMD. host kernel: mm/pgtable-generic.c:40: bad pmd 00000000b3152f68(8000000d2d2008e7) .... host kernel: BUG: Bad rss-counter state mm:00000000b583043d idx:1 val:512 host kernel: BUG: non-zero pgtables_bytes on freeing mm: 4096 The issue is observed on a v4.18-based distribution kernel, but the race window is expected to be applicable to mainline kernels, as well.

[PATCH] pid: Fix error return value in some cases

by minyard＠acm.org

From: Corey Minyard <cminyard(a)mvista.com> Recent changes to alloc_pid() allow the pid number to be specified on the command line. If set_tid_size is set, then the code scanning the levels will hard-set retval to -EPERM, overriding it's previous -ENOMEM value. After the code scanning the levels, there are error returns that do not set retval, assuming it is still set to -ENOMEM. In the first place, pid_ns_prepare_proc() returns its own error, just use that. In the second place: if (!(ns->pid_allocated & PIDNS_ADDING)) goto out_unlock; a return value of -ENOMEM is probably wrong, since that means that the namespace is in deletion while this happened. -EINVAL is probably a better choice.

[PATCH 1/2] xhci: Do not open code __print_symbolic() in xhci trace events

by Mathias Nyman

From: "Steven Rostedt (VMware)" <rostedt(a)goodmis.org> libtraceevent (used by perf and trace-cmd) failed to parse the xhci_urb_dequeue trace event. This is because the user space trace event format parsing is not a full C compiler. It can handle some basic logic, but is not meant to be able to handle everything C can do. In cases where a trace event field needs to be converted from a number to a string, there's the __print_symbolic() macro that should be used: See samples/trace_events/trace-events-sample.h Some xhci trace events open coded the __print_symbolic() causing the user spaces tools to fail to parse it. This has to be replaced with __print_symbolic() instead.

[PATCH 1/3] drm/i915/execlists: Enable timeslice on partial virtual engine dequeue

by Chris Wilson

If we stop filling the ELSP due to an incompatible virtual engine request, check if we should enable the timeslice on behalf of the queue. This fixes the case where we are inspecting the last->next element when we know that the last element is the last request in the execution queue, and so decided we did not need to enable timeslicing despite the intent to do so!
