However, the apic access functions for Hyper-V enlightened apic assume xapic mode only. As a result, Linux fails to bring up secondary cpus when run as a guest in QEMU/KVM with both hv_apic and x2apic enabled. According to Michael Kelley, when in x2apic mode, the Hyper-V synthetic apic MSRs behave exactly the same as the corresponding architectural x2apic MSRs, so there's no need to override the apic accessors.

If this is the case attributes is not being copied from remote to local, so, it is already known that the local copy has stale metadata. That's why the inode needs to be marked for revalidation in order to tell the VFS to lookup the dentry again before openning a file. This prevents unexpected stale errors to be returned to the user space when openning a file.

[PATCH v2] md: no longer compare spare disk superblock events in super_load

by Yufen Yu

We have a test case as follow: mdadm -CR /dev/md1 -l 1 -n 4 /dev/sd[a-d] --assume-clean --bitmap=internal mdadm -S /dev/md1 mdadm -A /dev/md1 /dev/sd[b-c] --run --force mdadm --zero /dev/sda mdadm /dev/md1 -a /dev/sda echo offline > /sys/block/sdc/device/state echo offline > /sys/block/sdb/device/state sleep 5 mdadm -S /dev/md1 echo running > /sys/block/sdb/device/state echo running > /sys/block/sdc/device/state mdadm -A /dev/md1 /dev/sd[a-c] --run --force When we readd /dev/sda to the array, it started to do recovery. After offline the other two disks in md1, the recovery have been interrupted and superblock update info cannot be written to the offline disks. While the spare disk (/dev/sda) can continue to update superblock info. After stopping the array and assemble it, we found the array run fail, with the follow kernel message: [ 172.986064] md: kicking non-fresh sdb from array! [ 173.004210] md: kicking non-fresh sdc from array! [ 173.022383] md/raid1:md1: active with 0 out of 4 mirrors [ 173.022406] md1: failed to create bitmap (-5) [ 173.023466] md: md1 stopped. Since both sdb and sdc have the value of 'sb->events' smaller than that in sda, they have been kicked from the array. However, the only remained disk sda is in 'spare' state before stop and it cannot be added to conf->mirrors[] array. In the end, raid array assemble and run fail. In fact, we can use the older disk sdb or sdc to assemble the array. That means we should not choose the 'spare' disk as the fresh disk in analyze_sbs(). To fix the problem, we do not compare superblock events when it is a spare disk, as same as validate_super.

[PATCH v5.3, v4.19] gpiolib: don't clear FLAG_IS_OUT when emulating open-drain/open-source

by Bartosz Golaszewski

From: Bartosz Golaszewski <bgolaszewski(a)baylibre.com> When emulating open-drain/open-source by not actively driving the output lines - we're simply changing their mode to input. This is wrong as it will then make it impossible to change the value of such line - it's now considered to actually be in input mode. If we want to still use the direction_input() callback for simplicity then we need to set FLAG_IS_OUT manually in gpiod_direction_output() and not clear it in gpio_set_open_drain_value_commit() and gpio_set_open_source_value_commit().

[PATCH 1/7] PCI/PM: Always return devices to D0 when thawing

by Bjorn Helgaas

From: Dexuan Cui <decui(a)microsoft.com> pci_pm_thaw_noirq() is supposed to return the device to D0 and restore its configuration registers, but previously it only did that for devices whose drivers implemented the new power management ops. Hibernation, e.g., via "echo disk > /sys/power/state", involves freezing devices, creating a hibernation image, thawing devices, writing the image, and powering off. The fact that thawing did not return devices with legacy power management to D0 caused errors, e.g., in this path: pci_pm_thaw_noirq if (pci_has_legacy_pm_support(pci_dev)) # true for Mellanox VF driver return pci_legacy_resume_early(dev) # ... legacy PM skips the rest pci_set_power_state(pci_dev, PCI_D0) pci_restore_state(pci_dev) pci_pm_thaw if (pci_has_legacy_pm_support(pci_dev)) pci_legacy_resume drv->resume mlx4_resume ... pci_enable_msix_range ... if (dev->current_state != PCI_D0) # <--- return -EINVAL; which caused these warnings: mlx4_core a6d1:00:02.0: INTx is not supported in multi-function mode, aborting PM: dpm_run_callback(): pci_pm_thaw+0x0/0xd7 returns -95 PM: Device a6d1:00:02.0 failed to thaw: error -95 Return devices to D0 and restore config registers for all devices, not just those whose drivers support new power management.

The changes introduced by that commit moved the limit enforcement into the allocation core and as a result the allocation functions returning physical address also started to limit allocations to memblock.current_limit.

[patch 16/16] mm/memory-failure: poison read receives SIGKILL instead of SIGBUS if mmaped more than once

by akpm＠linux-foundation.org

From: Jane Chu <jane.chu(a)oracle.com> Subject: mm/memory-failure: poison read receives SIGKILL instead of SIGBUS if mmaped more than once Mmap /dev/dax more than once, then read the poison location using address from one of the mappings. The other mappings due to not having the page mapped in will cause SIGKILLs delivered to the process. SIGKILL succeeds over SIGBUS, so user process loses the opportunity to handle the UE. Although one may add MAP_POPULATE to mmap(2) to work around the issue, MAP_POPULATE makes mapping 128GB of pmem several magnitudes slower, so isn't always an option.

[patch 09/16] mm, compaction: fix wrong pfn handling in __reset_isolation_pfn()

by akpm＠linux-foundation.org

From: Vlastimil Babka <vbabka(a)suse.cz> Subject: mm, compaction: fix wrong pfn handling in __reset_isolation_pfn() Florian and Dave reported [1] a NULL pointer dereference in __reset_isolation_pfn(). While the exact cause is unclear, staring at the code revealed two bugs, which might be related. One bug is that if zone starts in the middle of pageblock, block_page might correspond to different pfn than block_pfn, and then the pfn_valid_within() checks will check different pfn's than those accessed via struct page. This might result in acessing an unitialized page in CONFIG_HOLES_IN_ZONE configs. The other bug is that end_page refers to the first page of next pageblock and not last page of current pageblock. The online and valid check is then wrong and with sections, the while (page < end_page) loop might wander off actual struct page arrays.

[patch 04/16] mm/slub: fix a deadlock in show_slab_objects()

by akpm＠linux-foundation.org

From: Qian Cai <cai(a)lca.pw> Subject: mm/slub: fix a deadlock in show_slab_objects() A long time ago we fixed a similar deadlock in show_slab_objects() [1]. However, it is apparently due to the commits like 01fb58bcba63 ("slab: remove synchronous synchronize_sched() from memcg cache deactivation path") and 03afc0e25f7f ("slab: get_online_mems for kmem_cache_{create,destroy,shrink}"), this kind of deadlock is back by just reading files in /sys/kernel/slab which will generate a lockdep splat below. Since the "mem_hotplug_lock" here is only to obtain a stable online node mask while racing with NUMA node hotplug, in the worst case, the results may me miscalculated while doing NUMA node hotplug, but they shall be corrected by later reads of the same files.

[PATCH bpf-next 2/2] bpf/stackmap: fix A-A deadlock in bpf_get_stack()

by Song Liu

bpf stackmap with build-id lookup (BPF_F_STACK_BUILD_ID) can trigger A-A deadlock on rq_lock(): rcu: INFO: rcu_sched detected stalls on CPUs/tasks: [...] Call Trace: try_to_wake_up+0x1ad/0x590 wake_up_q+0x54/0x80 rwsem_wake+0x8a/0xb0 bpf_get_stack+0x13c/0x150 bpf_prog_fbdaf42eded9fe46_on_event+0x5e3/0x1000 bpf_overflow_handler+0x60/0x100 __perf_event_overflow+0x4f/0xf0 perf_swevent_overflow+0x99/0xc0 ___perf_sw_event+0xe7/0x120 __schedule+0x47d/0x620 schedule+0x29/0x90 futex_wait_queue_me+0xb9/0x110 futex_wait+0x139/0x230 do_futex+0x2ac/0xa50 __x64_sys_futex+0x13c/0x180 do_syscall_64+0x42/0x100 entry_SYSCALL_64_after_hwframe+0x44/0xa9 This can be reproduced by: 1. Start a multi-thread program that does parallel mmap() and malloc(); 2. taskset the program to 2 CPUs; 3. Attach bpf program to trace_sched_switch and gather stackmap with build-id, e.g. with trace.py from bcc tools: trace.py -U -p <pid> -s <some-bin,some-lib> t:sched:sched_switch A sample reproducer is attached at the end. Fix this by checking whether rq_lock is already locked. If so, postpone the up_read() to irq_work, just like the in_nmi() case.

[PATCH v4.14] gpiolib: don't clear FLAG_IS_OUT when emulating open-drain/open-source

by Bartosz Golaszewski

From: Bartosz Golaszewski <bgolaszewski(a)baylibre.com> When emulating open-drain/open-source by not actively driving the output lines - we're simply changing their mode to input. This is wrong as it will then make it impossible to change the value of such line - it's now considered to actually be in input mode. If we want to still use the direction_input() callback for simplicity then we need to set FLAG_IS_OUT manually in gpiod_direction_output() and not clear it in gpio_set_open_drain_value_commit() and gpio_set_open_source_value_commit().

There may be a race when two conversions complete at the same time on several ADCs. EOC can be read as 'set' for several ADCs, with: - an ADC configured to use IRQs. EOCIE bit is set. The handler is normally called in this case. - an ADC configured to use DMA. EOCIE bit isn't set. EOC triggers the DMA request instead. It's then automatically cleared by DMA read. But the handler gets called due to status bit is temporarily set (IRQ triggered by the other ADC). So both EOC status bit in CSR and EOCIE control bit must be checked before invoking the interrupt handler (e.g. call ISR only for IRQ-enabled ADCs).

patch "staging: wlan-ng: fix exit return when sme->key_idx >= NUM_WEPKEYS" added to staging-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled staging: wlan-ng: fix exit return when sme->key_idx >= NUM_WEPKEYS to my staging git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git in the staging-linus branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release. If you have any questions about this process, please let me know. >From 153c5d8191c26165dbbd2646448ca7207f7796d0 Mon Sep 17 00:00:00 2001 From: Colin Ian King <colin.king(a)canonical.com> Date: Mon, 14 Oct 2019 12:02:01 +0100 Subject: staging: wlan-ng: fix exit return when sme->key_idx >= NUM_WEPKEYS Currently the exit return path when sme->key_idx >= NUM_WEPKEYS is via label 'exit' and this checks if result is non-zero, however result has not been initialized and contains garbage.

[RFT PATCH] xhci: Fix use-after-free regression in xhci clear hub TT implementation

by Mathias Nyman

commit ef513be0a905 ("usb: xhci: Add Clear_TT_Buffer") schedules work to clear TT buffer, but causes a use-after-free regression at the same time Make sure hub_tt_work finishes before endpoint is disabled, otherwise the work will dereference already freed endpoint and device related pointers. This was triggered when usb core failed to read the configuration descriptor of a FS/LS device during enumeration. xhci driver queued clear_tt_work while usb core freed and reallocated a new device for the next enumeration attempt. EHCI driver implents ehci_endpoint_disable() that makes sure clear_tt_work has finished before it returns, but xhci lacks this support. usb core will call hcd->driver->endpoint_disable() callback before disabling endpoints, so we want this in xhci as well. The added xhci_endpoint_disable() is based on ehci_endpoint_disable() Fixes: ef513be0a905 ("usb: xhci: Add Clear_TT_Buffer") Cc: <stable(a)vger.kernel.org> # v5.3 Reported-by: Johan Hovold <johan(a)kernel.org> Signed-off-by: Mathias Nyman <mathias.nyman(a)linux.intel.com> --- drivers/usb/host/xhci.c | 43 +++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 43 insertions(+) diff --git a/drivers/usb/host/xhci.c b/drivers/usb/host/xhci.c index 5cfbf9a04494..6e817686d04f 100644 --- a/drivers/usb/host/xhci.c +++ b/drivers/usb/host/xhci.c @@ -3071,6 +3071,48 @@ void xhci_cleanup_stalled_ring(struct xhci_hcd *xhci, unsigned int ep_index, } } +static void xhci_endpoint_disable(struct usb_hcd *hcd, + struct usb_host_endpoint *host_ep) +{ + struct xhci_hcd *xhci; + struct xhci_virt_device *vdev; + struct xhci_virt_ep *ep; + struct usb_device *udev; + unsigned long flags; + unsigned int ep_index; + + xhci = hcd_to_xhci(hcd); +rescan: + spin_lock_irqsave(&xhci->lock, flags); + + udev = (struct usb_device *)host_ep->hcpriv; + if (!udev || !udev->slot_id) + goto done; + + vdev = xhci->devs[udev->slot_id]; + if (!vdev) + goto done; + + ep_index = xhci_get_endpoint_index(&host_ep->desc); + ep = &vdev->eps[ep_index]; + if (!ep) + goto done; + + /* wait for hub_tt_work to finish clearing hub TT */ + if (ep->ep_state & EP_CLEARING_TT) { + spin_unlock_irqrestore(&xhci->lock, flags); + schedule_timeout_uninterruptible(1); + goto rescan; + } + + if (ep->ep_state) + xhci_dbg(xhci, "endpoint disable with ep_state 0x%x\n", + ep->ep_state); +done: + host_ep->hcpriv = NULL; + spin_unlock_irqrestore(&xhci->lock, flags); +} + /* * Called after usb core issues a clear halt control message. * The host side of the halt should already be cleared by a reset endpoint @@ -5290,6 +5332,7 @@ static const struct hc_driver xhci_hc_driver = { .free_streams = xhci_free_streams, .add_endpoint = xhci_add_endpoint, .drop_endpoint = xhci_drop_endpoint, + .endpoint_disable = xhci_endpoint_disable, .endpoint_reset = xhci_endpoint_reset, .check_bandwidth = xhci_check_bandwidth, .reset_bandwidth = xhci_reset_bandwidth, -- 2.7.4

[PATCH for-stable-4.19 0/3] ACPI, arm64: Backport for ACPI PPTT 6.3 thread flag

by John Garry

This series is a backport of the ACPI PPTT 6.3 thread flag feature for supporting arm64 systems. The background is that some arm64 implementations are broken, in that they incorrectly advertise that a CPU is mutli-threaded, when it is not - the HiSilicon Taishanv110 rev 2, aka tsv110, being an example. This leads to the system topology being incorrect. The reason being that arm64 topology code uses a combination of ACPI PPTT (Processor Properties Topology Table) and the system MPIDR (Multiprocessor Affinity Register) MT bit to determine the topology. Until ACPI 6.3, the PPTT did not have any method to determine whether a CPU was multi-threaded, so only the MT bit is used - hence the broken topology for some systems. In ACPI 6.3, a PPTT thread flag was introduced, which - when supported - would be used by the kernel to determine really if a CPU is multi-threaded or not, so that we don't get incorrect topology.

[PATCH 0/3] Logitech G920 fixes

by Andrey Smirnov

Everyone: This series contains patches to fix a couple of regressions in G920 wheel support by hid-logitech-hidpp driver. Without the patches the wheel remains stuck in autocentering mode ("resisting" any attempt to trun) as well as missing support for any FF action. Thanks, Andrey Smirnov Andrey Smirnov (3): HID: logitech-hidpp: use devres to manage FF private data HID: logitech-hidpp: split g920_get_config() HID: logitech-hidpp: add G920 device validation quirk drivers/hid/hid-logitech-hidpp.c | 193 +++++++++++++++++++------------ 1 file changed, 120 insertions(+), 73 deletions(-) -- 2.21.0

But Govind just pointed out to me that I hastily missed the fact that this code path leaks the dequeued skb. So I'll respin the patch to fix both issues at once.

[PATCH] drm/i915: Favor last VBT child device with conflicting AUX ch/DDC pin

by Ville Syrjala

From: Ville Syrjälä <ville.syrjala(a)linux.intel.com> The first come first served apporoach to handling the VBT child device AUX ch conflicts has backfired. We have machines in the wild where the VBT specifies both port A eDP and port E DP (in that order) with port E being the real one. So let's try to flip the preference around and let the last child device win once again.

[PATCH v4] dmaengine: tegra210-adma: fix transfer failure

by Sameer Pujar

>From Tegra186 onwards OUTSTANDING_REQUESTS field is added in channel configuration register(bits 7:4) which defines the maximum number of reads from the source and writes to the destination that may be outstanding at any given point of time. This field must be programmed with a value between 1 and 8. A value of 0 will prevent any transfers from happening. Thus added 'has_outstanding_reqs' bool member in chip data structure and is set to false for Tegra210, since the field is not applicable. For Tegra186 it is set to true and channel configuration is updated with maximum outstanding requests.

[PATCH v4 2/3] powerpc: Avoid clang warnings around setjmp and longjmp

by Nathan Chancellor

Commit aea447141c7e ("powerpc: Disable -Wbuiltin-requires-header when setjmp is used") disabled -Wbuiltin-requires-header because of a warning about the setjmp and longjmp declarations. r367387 in clang added another diagnostic around this, complaining that there is no jmp_buf declaration. In file included from ../arch/powerpc/xmon/xmon.c:47: ../arch/powerpc/include/asm/setjmp.h:10:13: error: declaration of built-in function 'setjmp' requires the declaration of the 'jmp_buf' type, commonly provided in the header <setjmp.h>. [-Werror,-Wincomplete-setjmp-declaration] extern long setjmp(long *); ^ ../arch/powerpc/include/asm/setjmp.h:11:13: error: declaration of built-in function 'longjmp' requires the declaration of the 'jmp_buf' type, commonly provided in the header <setjmp.h>.

[for-linus][PATCH 10/11] tracing/hwlat: Dont ignore outer-loop duration when calculating max_latency

by Steven Rostedt

From: "Srivatsa S. Bhat (VMware)" <srivatsa(a)csail.mit.edu> max_latency is intended to record the maximum ever observed hardware latency, which may occur in either part of the loop (inner/outer). So we need to also consider the outer-loop sample when updating max_latency.

[for-linus][PATCH 09/11] tracing/hwlat: Report total time spent in all NMIs during the sample

by Steven Rostedt

From: "Srivatsa S. Bhat (VMware)" <srivatsa(a)csail.mit.edu> nmi_total_ts is supposed to record the total time spent in *all* NMIs that occur on the given CPU during the (active portion of the) sampling window. However, the code seems to be overwriting this variable for each NMI, thereby only recording the time spent in the most recent NMI. Fix it by accumulating the duration instead.

[PATCH] btrfs: don't needlessly create extent-refs kernel thread

by David Sterba

The patch 32b593bfcb58 ("Btrfs: remove no longer used function to run delayed refs asynchronously") removed the async delayed refs but the thread has been created, without any use.

[PATCH v5.2 1/2] iwlwifi: mvm: add a wrapper around rs_tx_status to handle locks

by Luca Coelho

From: Gregory Greenman <gregory.greenman(a)intel.com> [ Upstream commit 23babdf06779482a65c5072a145d826a62979534 ] iwl_mvm_rs_tx_status can be called from two places in the code, but the mutex is taken only on one of the calls. Split it into a wrapper taking locks and an internal __iwl_mvm_rs_tx_status function.

[PATCH 3/7 v2] tracing: Get trace_array reference for available_tracers files

by Steven Rostedt

From: "Steven Rostedt (VMware)" <rostedt(a)goodmis.org> As instances may have different tracers available, we need to look at the trace_array descriptor that shows lists the available tracers for the instance. But there's a race between opening the file and the admin from deleting the instance. The trace_array_get() needs to be called before accessing the trace_array.

[PATCH 2/7 v2] ftrace: Get a reference counter for the trace_array on filter files

by Steven Rostedt

From: "Steven Rostedt (VMware)" <rostedt(a)goodmis.org> The ftrace set_ftrace_filter and set_ftrace_notrace files are specific for an instance now. They need to take a reference to the instance otherwise there could be a race between accessing the files and deleting the instance.

When shutdown_cache() is called from the kmem_cache_destroy() context, a memcg kmem_cache might have empty slab pages in a partial list, which are still charged to the memory cgroup. These pages are released by free_partial() at the beginning of shutdown_cache(): either directly or by scheduling a RCU-delayed work (if the kmem_cache has the SLAB_TYPESAFE_BY_RCU flag). The latter case is when the reported panic can happen: memcg_unlink_cache() is called immediately after shrinking partial lists, without waiting for scheduled RCU works. It sets the kmem_cache->memcg_params.memcg pointer to NULL, and the following attempt to dereference it by __free_slab() from the RCU work context causes the panic. To fix the issue, let's postpone the release of the memcg pointer to destroy_memcg_params(). It's called from a separate work context by slab_caches_to_rcu_destroy_workfn(), which contains a full RCU barrier. This guarantees that all scheduled page release RCU works will complete before the memcg pointer will be zeroed. Big thanks for Karsten for the perfect report containing all necessary information, his help with the analysis of the problem and testing of the fix.

[tip: x86/urgent] x86/boot/64: Make level2_kernel_pgt pages invalid outside kernel area

Access to these ranges is caught as an error, causing the BIOS to halt the system. Initial page tables mapped a large range of physical addresses that were not checked against the list of BIOS reserved addresses, and sometimes included reserved addresses in part of the mapped range. Including the reserved range in the map allowed processor speculative accesses to the reserved range, triggering a BIOS halt. Used early in booting, the page table level2_kernel_pgt addresses 1 GiB divided into 2 MiB pages, and it was set up to linearly map a full 1 GiB of physical addresses that included the physical address range of the kernel image, as chosen by KASLR. But this also included a large range of unused addresses on either side of the kernel image. And unlike the kernel image's physical address range, this extra mapped space was not checked against the BIOS tables of usable RAM addresses. So there were times when the addresses chosen by KASLR would result in processor accessible mappings of BIOS reserved physical addresses. The kernel code did not directly access any of this extra mapped space, but having it mapped allowed the processor to issue speculative accesses into reserved memory, causing system halts. This was encountered somewhat rarely on a normal system boot, and much more often when starting the crash kernel if "crashkernel=512M,high" was specified on the command line (this heavily restricts the physical address of the crash kernel, in our case usually within 1 GiB of reserved space). The solution is to invalidate the pages of this table outside the kernel image's space before the page table is activated. It fixes this problem on our hardware.

When shutdown_cache() is called from the kmem_cache_destroy() context, a memcg kmem_cache might have empty slab pages in a partial list, which are still charged to the memory cgroup. These pages are released by free_partial() at the beginning of shutdown_cache(): either directly or by scheduling a RCU-delayed work (if the kmem_cache has the SLAB_TYPESAFE_BY_RCU flag). The latter case is when the reported panic can happen: memcg_unlink_cache() is called immediately after shrinking partial lists, without waiting for scheduled RCU works. It sets the kmem_cache->memcg_params.memcg pointer to NULL, and the following attempt to dereference it by __free_slab() from the RCU work context causes the panic. To fix the issue, let's postpone the release of the memcg pointer to destroy_memcg_params(). It's called from a separate work context by slab_caches_to_rcu_destroy_workfn(), which contains a full RCU barrier. This guarantees that all scheduled page release RCU works will complete before the memcg pointer will be zeroed. Big thanks for Karsten for the perfect report containing all necessary information, his help with the analysis of the problem and testing of the fix.

[EMBARGOED RHEL8.1 PATCH v5 03/14] KVM: x86/mmu: Reintroduce fast invalidate/zap for flushing memslot

by Paolo Bonzini

From: Sean Christopherson <sean.j.christopherson(a)intel.com> James Harvey reported a livelock that was introduced by commit d012a06ab1d23 ("Revert "KVM: x86/mmu: Zap only the relevant pages when removing a memslot""). The livelock occurs because kvm_mmu_zap_all() as it exists today will voluntarily reschedule and drop KVM's mmu_lock, which allows other vCPUs to add shadow pages. With enough vCPUs, kvm_mmu_zap_all() can get stuck in an infinite loop as it can never zap all pages before observing lock contention or the need to reschedule. The equivalent of kvm_mmu_zap_all() that was in use at the time of the reverted commit (4e103134b8623, "KVM: x86/mmu: Zap only the relevant pages when removing a memslot") employed a fast invalidate mechanism and was not susceptible to the above livelock. There are three ways to fix the livelock: - Reverting the revert (commit d012a06ab1d23) is not a viable option as the revert is needed to fix a regression that occurs when the guest has one or more assigned devices. It's unlikely we'll root cause the device assignment regression soon enough to fix the regression timely. - Remove the conditional reschedule from kvm_mmu_zap_all(). However, although removing the reschedule would be a smaller code change, it's less safe in the sense that the resulting kvm_mmu_zap_all() hasn't been used in the wild for flushing memslots since the fast invalidate mechanism was introduced by commit 6ca18b6950f8d ("KVM: x86: use the fast way to invalidate all pages"), back in 2013. - Reintroduce the fast invalidate mechanism and use it when zapping shadow pages in response to a memslot being deleted/moved, which is what this patch does. For all intents and purposes, this is a revert of commit ea145aacf4ae8 ("Revert "KVM: MMU: fast invalidate all pages"") and a partial revert of commit 7390de1e99a70 ("Revert "KVM: x86: use the fast way to invalidate all pages""), i.e. restores the behavior of commit 5304b8d37c2a5 ("KVM: MMU: fast invalidate all pages") and commit 6ca18b6950f8d ("KVM: x86: use the fast way to invalidate all pages") respectively.

[PATCH] mac80211: More strictly validate .abort_scan

by Denis Kenzior

nl80211 requires NL80211_CMD_ABORT_SCAN to have a wdev or netdev attribute present and checks that if netdev is provided it is UP. However, mac80211 does not check that an ongoing scan actually belongs to the netdev/wdev provided by the user. In other words, it is possible for an application to cancel scans on an interface it doesn't manage.

patch "firmware: google: increment VPD key_len properly" added to char-misc-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled firmware: google: increment VPD key_len properly to my char-misc git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git in the char-misc-linus branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release. If you have any questions about this process, please let me know. >From 442f1e746e8187b9deb1590176f6b0ff19686b11 Mon Sep 17 00:00:00 2001 From: Brian Norris <briannorris(a)chromium.org> Date: Mon, 30 Sep 2019 14:45:22 -0700 Subject: firmware: google: increment VPD key_len properly Commit 4b708b7b1a2c ("firmware: google: check if size is valid when decoding VPD data") adds length checks, but the new vpd_decode_entry() function botched the logic -- it adds the key length twice, instead of adding the key and value lengths separately. On my local system, this means vpd.c's vpd_section_create_attribs() hits an error case after the first attribute it parses, since it's no longer looking at the correct offset. With this patch, I'm back to seeing all the correct attributes in /sys/firmware/vpd/...

[PATCH ARM64 v4.4 V3 00/44] V4.4 backport of arm64 Spectre patches

by Viresh Kumar

Hello, This series backports arm64 spectre patches to v4.4 stable kernel. I have started this backport with Mark Rutland's backport of Spectre to 4.9 [1] and tried applying the upstream version of them over 4.4 and resolved conflicts by checking how they have been resolved in 4.9. The KVM changes are mostly dropped as the KVM code in v4.4 is quite different and it makes backport more complex. This was suggested by the ARM team. I had to pick few extra upstream patches to avoid conflicts and to make things work: mm/kasan: add API to check memory regions arm64: kasan: instrument user memory access API arm64: cpufeature: Add scope for capability check arm64: cputype info for Broadcom Vulcan arm64: cputype: Add MIDR values for Cavium ThunderX2 CPUs ARM: 8478/2: arm/arm64: add arm-smccc arm64: cpufeature: Test 'matches' pointer to find the end of the list arm64: Introduce cpu_die_early arm64: Move cpu_die_early to smp.c arm64: Verify CPU errata work arounds on hotplugged CPU arm64: errata: Calling enable functions for CPU errata too arm64: Rearrange CPU errata workaround checks arm64: Add a helper for parking CPUs in a loop I also had to drop few patches as they weren't getting applied properly due to missing files/features or they were KVM related: arm64: cpufeature: __this_cpu_has_cap() shouldn't stop early arm64: KVM: Use per-CPU vector when BP hardening is enabled arm64: KVM: Make PSCI_VERSION a fast path mm: Introduce lm_alias arm64: KVM: Increment PC after handling an SMC trap arm/arm64: KVM: Consolidate the PSCI include files arm/arm64: KVM: Add PSCI_VERSION helper arm/arm64: KVM: Add smccc accessors to PSCI code arm/arm64: KVM: Implement PSCI 1.0 support arm/arm64: KVM: Turn kvm_psci_version into a static inline arm64: KVM: Add SMCCC_ARCH_WORKAROUND_1 fast handling The patches in this series are pushed here [2]. This is tested on Hikey board (octa A53) and I verified that BP hardening code is getting hit for CPUs (had to hack a bit and enable BP hardening support for A53 for this).

[PATCH ARM32 v4.4 V2 00/47] V4.4 backport of arm32 Spectre patches

by Viresh Kumar

Hello, Here is an attempt to backport arm32 spectre patches to v4.4 stable tree. This was last tried around an year back by David Long [1]. He was backporting only a subset (18) of patches and this series include a lot of other patches present in Russell's spectre branch. Just like arm64 backport [2], KVM patches are dropped and they can be backported separately if required. Dropped patches (compared to Russell's spectre branch): KVM related: 3f7e8e2e1ebd ARM: KVM: invalidate BTB on guest exit for Cortex-A12/A17 0c47ac8cd157 ARM: KVM: invalidate icache on guest exit for Cortex-A15 3c908e16396d ARM: spectre-v2: KVM: invalidate icache on guest exit for Brahma B15 b800acfc70d9 ARM: KVM: Add SMCCC_ARCH_WORKAROUND_1 fast handling add5609877c6 ARM: KVM: report support for SMCCC_ARCH_WORKAROUND_1 Dropped in 4.9 backport as well: 73839798af7e ARM: 8790/1: signal: always use __copy_to_user to save iwmmxt context Additional patches picked to avoid rebase conflicts and build issues: 9f73bd8bb445 ARM: uaccess: remove put_user() code duplication 122e022eebb3 arch: Introduce post-init read-only memory 7b90ba3eb4af ARM: 8595/2: apply more __ro_after_init SMCCC related patches, are part of arm64 backport [2] as well and all KVM related changes are dropped from them: 56b35dfda10c ARM: 8478/2: arm/arm64: add arm-smccc e6e9cc47cea9 arm/arm64: KVM: Advertise SMCCC v1.1 91958fe7a4eb arm64: KVM: Report SMCCC_ARCH_WORKAROUND_1 BP hardening support 1b232ad7ca05 drivers/firmware: Expose psci_get_version through psci_ops structure df2030616c6f firmware/psci: Expose PSCI conduit 30f8c32765fd firmware/psci: Expose SMCCC version through psci_ops 17f6f98d5069 arm/arm64: smccc: Make function identifiers an unsigned quantity e6d9b2fef81e arm/arm64: smccc: Implement SMCCC v1.1 inline primitive All the patches are pushed here [3]. This is tested in Linaro Lava on Qemu_arm and X15 platforms and the results are here [4]. Lava also check for some Spectre tests and one of the test fails on x15 with this message: CVE-2018-3640: VULN (an up-to-date CPU microcode is needed to mitigate this vulnerability). Perhaps this is an issue with x15 setup and not the patches themselves ? I have also pushed this to be tested by kernel-ci, looks like my branch isn't getting tested there currently. I am co-ordinating with them to get it tested soon, we can start the review process until that time though. -- Viresh [1] https://lore.kernel.org/stable/20181031140436.2964-1-dave.long@linaro.org/ [2] https://lore.kernel.org/stable/cover.1562908074.git.viresh.kumar@linaro.org/ [3] https://git.kernel.org/pub/scm/linux/kernel/git/vireshk/linux.git stable/arm32/v4.4.y/spectre [4] https://staging-qa-reports.linaro.org/lkft/vishal.bhoj-stable-arm32-v4.4.y-… Ard Biesheuvel (1): ARM: 8809/1: proc-v7: fix Thumb annotation of cpu_v7_hvc_switch_mm Jens Wiklander (1): ARM: 8478/2: arm/arm64: add arm-smccc Julien Thierry (9): ARM: 8789/1: signal: copy registers using __copy_to_user() ARM: 8791/1: vfp: use __copy_to_user() when saving VFP state ARM: 8792/1: oabi-compat: copy oabi events using __copy_to_user() ARM: 8793/1: signal: replace __put_user_error with __put_user ARM: 8794/1: uaccess: Prevent speculative use of the current addr_limit ARM: 8795/1: spectre-v1.1: use put_user() for __put_user() ARM: 8796/1: spectre-v1,v1.1: provide helpers for address sanitization ARM: 8797/1: spectre-v1.1: harden __copy_to_user ARM: 8810/1: vfp: Fix wrong assignement to ufp_exc Kees Cook (2): arch: Introduce post-init read-only memory ARM: 8595/2: apply more __ro_after_init Marc Zyngier (6): arm/arm64: KVM: Advertise SMCCC v1.1 arm64: KVM: Report SMCCC_ARCH_WORKAROUND_1 BP hardening support firmware/psci: Expose PSCI conduit firmware/psci: Expose SMCCC version through psci_ops arm/arm64: smccc: Make function identifiers an unsigned quantity arm/arm64: smccc: Implement SMCCC v1.1 inline primitive Russell King (27): ARM: add more CPU part numbers for Cortex and Brahma B15 CPUs ARM: bugs: prepare processor bug infrastructure ARM: bugs: hook processor bug checking into SMP and suspend paths ARM: bugs: add support for per-processor bug checking ARM: spectre: add Kconfig symbol for CPUs vulnerable to Spectre ARM: spectre-v2: harden branch predictor on context switches ARM: spectre-v2: add Cortex A8 and A15 validation of the IBE bit ARM: spectre-v2: harden user aborts in kernel space ARM: spectre-v2: add firmware based hardening ARM: spectre-v2: warn about incorrect context switching functions ARM: spectre-v1: add speculation barrier (csdb) macros ARM: spectre-v1: add array_index_mask_nospec() implementation ARM: spectre-v1: fix syscall entry ARM: signal: copy registers using __copy_from_user() ARM: vfp: use __copy_from_user() when restoring VFP state ARM: oabi-compat: copy semops using __copy_from_user() ARM: use __inttype() in get_user() ARM: spectre-v1: use get_user() for __get_user() ARM: spectre-v1: mitigate user accesses ARM: uaccess: remove put_user() code duplication ARM: make lookup_processor_type() non-__init ARM: split out processor lookup ARM: clean up per-processor check_bugs method call ARM: add PROC_VTABLE and PROC_TABLE macros ARM: spectre-v2: per-CPU vtables to work around big.Little systems ARM: ensure that processor vtables is not lost after boot ARM: fix the cockup in the previous patch Will Deacon (1): drivers/firmware: Expose psci_get_version through psci_ops structure arch/arm/include/asm/assembler.h | 23 +++ arch/arm/include/asm/barrier.h | 32 ++++ arch/arm/include/asm/bugs.h | 6 +- arch/arm/include/asm/cp15.h | 18 ++ arch/arm/include/asm/cputype.h | 9 + arch/arm/include/asm/proc-fns.h | 65 +++++-- arch/arm/include/asm/system_misc.h | 15 ++ arch/arm/include/asm/thread_info.h | 8 +- arch/arm/include/asm/uaccess.h | 176 +++++++++++-------- arch/arm/kernel/Makefile | 1 + arch/arm/kernel/bugs.c | 18 ++ arch/arm/kernel/cpuidle.c | 2 +- arch/arm/kernel/entry-common.S | 18 +- arch/arm/kernel/entry-header.S | 25 +++ arch/arm/kernel/head-common.S | 6 +- arch/arm/kernel/setup.c | 50 +++--- arch/arm/kernel/signal.c | 126 +++++++------- arch/arm/kernel/smp.c | 38 +++- arch/arm/kernel/suspend.c | 2 + arch/arm/kernel/sys_oabi-compat.c | 16 +- arch/arm/lib/copy_from_user.S | 5 + arch/arm/lib/copy_to_user.S | 6 +- arch/arm/lib/delay.c | 2 +- arch/arm/lib/uaccess_with_memcpy.c | 3 +- arch/arm/mm/Kconfig | 23 +++ arch/arm/mm/Makefile | 2 +- arch/arm/mm/fault.c | 3 + arch/arm/mm/mmu.c | 2 +- arch/arm/mm/proc-macros.S | 13 +- arch/arm/mm/proc-v7-2level.S | 6 - arch/arm/mm/proc-v7-bugs.c | 161 +++++++++++++++++ arch/arm/mm/proc-v7.S | 154 +++++++++++++---- arch/arm/vfp/vfpmodule.c | 37 ++-- arch/parisc/include/asm/cache.h | 3 + drivers/firmware/Kconfig | 3 + drivers/firmware/psci.c | 58 ++++++- include/asm-generic/vmlinux.lds.h | 1 + include/linux/arm-smccc.h | 267 +++++++++++++++++++++++++++++ include/linux/cache.h | 14 ++ include/linux/psci.h | 14 ++ 40 files changed, 1174 insertions(+), 257 deletions(-) create mode 100644 arch/arm/kernel/bugs.c create mode 100644 arch/arm/mm/proc-v7-bugs.c create mode 100644 include/linux/arm-smccc.h -- 2.21.0.rc0.269.g1a574e7a288b

[PATCH v3] PCI: rcar: Fix missing MACCTLR register setting in rcar_pcie_hw_init()

by Yoshihiro Shimoda

According to the R-Car Gen2/3 manual, the bit 0 of MACCTLR register should be written to 0 before enabling PCIETCTLR.CFINIT because the bit 0 is set to 1 on reset. To avoid unexpected behaviors from this incorrect setting, this patch fixes it.

[PATCH v4] block: fix null pointer dereference in blk_mq_rq_timed_out()

by Yufen Yu

We got a null pointer deference BUG_ON in blk_mq_rq_timed_out() as following: [ 108.825472] BUG: kernel NULL pointer dereference, address: 0000000000000040 [ 108.827059] PGD 0 P4D 0 [ 108.827313] Oops: 0000 [#1] SMP PTI [ 108.827657] CPU: 6 PID: 198 Comm: kworker/6:1H Not tainted 5.3.0-rc8+ #431 [ 108.829503] Workqueue: kblockd blk_mq_timeout_work [ 108.829913] RIP: 0010:blk_mq_check_expired+0x258/0x330 [ 108.838191] Call Trace: [ 108.838406] bt_iter+0x74/0x80 [ 108.838665] blk_mq_queue_tag_busy_iter+0x204/0x450 [ 108.839074] ? __switch_to_asm+0x34/0x70 [ 108.839405] ? blk_mq_stop_hw_queue+0x40/0x40 [ 108.839823] ? blk_mq_stop_hw_queue+0x40/0x40 [ 108.840273] ? syscall_return_via_sysret+0xf/0x7f [ 108.840732] blk_mq_timeout_work+0x74/0x200 [ 108.841151] process_one_work+0x297/0x680 [ 108.841550] worker_thread+0x29c/0x6f0 [ 108.841926] ? rescuer_thread+0x580/0x580 [ 108.842344] kthread+0x16a/0x1a0 [ 108.842666] ? kthread_flush_work+0x170/0x170 [ 108.843100] ret_from_fork+0x35/0x40 The bug is caused by the race between timeout handle and completion for flush request. When timeout handle function blk_mq_rq_timed_out() try to read 'req->q->mq_ops', the 'req' have completed and reinitiated by next flush request, which would call blk_rq_init() to clear 'req' as 0. After commit 12f5b93145 ("blk-mq: Remove generation seqeunce"), normal requests lifetime are protected by refcount. Until 'rq->ref' drop to zero, the request can really be free. Thus, these requests cannot been reused before timeout handle finish. However, flush request has defined .end_io and rq->end_io() is still called even if 'rq->ref' doesn't drop to zero. After that, the 'flush_rq' can be reused by the next flush request handle, resulting in null pointer deference BUG ON. We fix this problem by covering flush request with 'rq->ref'. If the refcount is not zero, flush_end_io() return and wait the last holder recall it. To record the request status, we add a new entry 'rq_status', which will be used in flush_end_io().

[PATCH] MIPS: Disable Loongson MMI instructions for kernel build

by Paul Burton

GCC 9.x automatically enables support for Loongson MMI instructions when using some -march= flags, and then errors out when -msoft-float is specified with: cc1: error: ‘-mloongson-mmi’ must be used with ‘-mhard-float’ The kernel shouldn't be using these MMI instructions anyway, just as it doesn't use floating point instructions.

patch "USB: yurex: fix NULL-derefs on disconnect" added to usb-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled USB: yurex: fix NULL-derefs on disconnect to my usb git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git in the usb-linus branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release. If you have any questions about this process, please let me know. >From aafb00a977cf7d81821f7c9d12e04c558c22dc3c Mon Sep 17 00:00:00 2001 From: Johan Hovold <johan(a)kernel.org> Date: Wed, 9 Oct 2019 17:38:48 +0200 Subject: USB: yurex: fix NULL-derefs on disconnect The driver was using its struct usb_interface pointer as an inverted disconnected flag, but was setting it to NULL without making sure all code paths that used it were done with it.

[PATCH 12/29] can: rx-offload: can_rx_offload_queue_sorted(): fix error handling, avoid skb mem leak

by Marc Kleine-Budde

If the rx-offload skb_queue is full can_rx_offload_queue_sorted() will not queue the skb and return with an error. None of the callers of this function, issue a kfree_skb() to free the not queued skb. This results in a memory leak. This patch fixes the problem by freeing the skb in case of a full queue. The return value is adjusted to -ENOBUFS to better reflect the actual problem. The device stats handling is left to the callers, as this function mightbe used in both the rx and tx path.

by Marc Kleine-Budde

From: Stephane Grosjean <s.grosjean(a)peak-system.com> When decoding a buffer received from PCAN-USB, the first timestamp read in a packet is a 16-bit coded time base, and the next ones are an 8-bit offset to this base, regardless of the type of packet read.

[PATCH 05/29] can: flexcan: disable completely the ECC mechanism

by Marc Kleine-Budde

From: Joakim Zhang <qiangqing.zhang(a)nxp.com> The ECC (memory error detection and correction) mechanism can be activated or not, controlled by the ECCDIS bit in CAN_MECR. When disabled, updates on indications and reporting registers are stopped. So if want to disable ECC completely, had better assert ECCDIS bit, not just mask the related interrupts.

This could lead to a racing release() freeing the driver data before disconnect() is done with it. Due to insufficient locking a related use-after-free could be triggered also before the above mentioned commit. Specifically, the driver needs to hold the driver-data mutex also while checking the opened flag at disconnect().

This could lead to a NULL-pointer dereference in a number of dev_dbg, dev_warn and dev_err statements in the completion handlers which relies on said pointer. Fix this by unconditionally stopping all I/O and preventing resubmissions by poisoning the interrupt URBs at disconnect and using a dedicated disconnected flag. This also makes sure that all I/O has completed by the time the disconnect callback returns.

patch "USB: usb-skeleton: fix NULL-deref on disconnect" added to usb-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled USB: usb-skeleton: fix NULL-deref on disconnect to my usb git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git in the usb-linus branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release. If you have any questions about this process, please let me know. >From bed5ef230943863b9abf5eae226a20fad9a8ff71 Mon Sep 17 00:00:00 2001 From: Johan Hovold <johan(a)kernel.org> Date: Wed, 9 Oct 2019 19:09:42 +0200 Subject: USB: usb-skeleton: fix NULL-deref on disconnect The driver was using its struct usb_interface pointer as an inverted disconnected flag and was setting it to NULL before making sure all completion handlers had run. This could lead to NULL-pointer dereferences in the dev_err() statements in the completion handlers which relies on said pointer. Fix this by using a dedicated disconnected flag. Note that this is also addresses a NULL-pointer dereference at release() and a struct usb_interface reference leak introduced by a recent runtime PM fix, which depends on and should have been submitted together with this patch.

[git:media_tree/master] media: usbvision: Fix races among open, close, and disconnect

by Mauro Carvalho Chehab

This is an automatic generated email to let you know that the following patch were queued: Subject: media: usbvision: Fix races among open, close, and disconnect Author: Alan Stern <stern(a)rowland.harvard.edu> Date: Mon Oct 7 12:09:53 2019 -0300 Visual inspection of the usbvision driver shows that it suffers from three races between its open, close, and disconnect handlers. In particular, the driver is careful to update its usbvision->user and usbvision->remove_pending flags while holding the private mutex, but: usbvision_v4l2_close() and usbvision_radio_close() don't hold the mutex while they check the value of usbvision->remove_pending; usbvision_disconnect() doesn't hold the mutex while checking the value of usbvision->user; and also, usbvision_v4l2_open() and usbvision_radio_open() don't check whether the device has been unplugged before allowing the user to open the device files. Each of these can potentially lead to usbvision_release() being called twice and use-after-free errors. This patch fixes the races by reading the flags while the mutex is still held and checking for pending removes before allowing an open to succeed.

[git:media_tree/master] media: usbvision: Fix invalid accesses after device disconnect

by Mauro Carvalho Chehab

This is an automatic generated email to let you know that the following patch were queued: Subject: media: usbvision: Fix invalid accesses after device disconnect Author: Alan Stern <stern(a)rowland.harvard.edu> Date: Mon Oct 7 12:09:04 2019 -0300 The syzbot fuzzer found two invalid-access bugs in the usbvision driver. These bugs occur when userspace keeps the device file open after the device has been disconnected and usbvision_disconnect() has set usbvision->dev to NULL: When the device file is closed, usbvision_radio_close() tries to issue a usb_set_interface() call, passing the NULL pointer as its first argument. If userspace performs a querycap ioctl call, vidioc_querycap() calls usb_make_path() with the same NULL pointer. This patch fixes the problems by making the appropriate tests beforehand. Note that vidioc_querycap() is protected by usbvision->v4l2_lock, acquired in a higher layer of the V4L2 subsystem.

There may be a race when two conversions complete at the same time on several ADCs. EOC can be read as 'set' for several ADCs, with: - an ADC configured to use IRQs. EOCIE bit is set. The handler is normally called in this case. - an ADC configured to use DMA. EOCIE bit isn't set. EOC triggers the DMA request instead. It's then automatically cleared by DMA read. But the handler gets called due to status bit is temporarily set (IRQ triggered by the other ADC).

patch "iio: adc: stm32-adc: move registers definitions" added to staging-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled iio: adc: stm32-adc: move registers definitions to my staging git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git in the staging-linus branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release. If you have any questions about this process, please let me know. >From 31922f62bb527d749b99dbc776e514bcba29b7fe Mon Sep 17 00:00:00 2001 From: Fabrice Gasnier <fabrice.gasnier(a)st.com> Date: Tue, 17 Sep 2019 14:38:15 +0200 Subject: iio: adc: stm32-adc: move registers definitions Move STM32 ADC registers definitions to common header.

If PD_SCK is high for at least 60 us power down mode of the sensor is entered which in turn leads to a wrong measurement. Switch off interrupts during a PD_SCK high period and move query of DOUT to the latest point of time which is at the end of PD_SCK low period. This bug exists in the driver since it's initial addition. The more interrupts on the system the higher is the probability that it happens.

patch "iio: accel: adxl372: Fix push to buffers lost samples" added to staging-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled iio: accel: adxl372: Fix push to buffers lost samples to my staging git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git in the staging-linus branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release. If you have any questions about this process, please let me know. >From 62df81b74393079debf04961c48cb22268fc5fab Mon Sep 17 00:00:00 2001 From: Stefan Popa <stefan.popa(a)analog.com> Date: Tue, 10 Sep 2019 17:44:21 +0300 Subject: iio: accel: adxl372: Fix push to buffers lost samples One in two sample sets was lost by multiplying fifo_set_size with sizeof(u16).

[PATCH] cpufreq: Fix RCU reboot regression on x86 PIC machines

by Ville Syrjala

From: Ville Syrjälä <ville.syrjala(a)linux.intel.com> Since 4.20-rc1 my PIC machines no longer reboot/shutdown. I bisected this down to commit 45975c7d21a1 ("rcu: Define RCU-sched API in terms of RCU for Tree RCU PREEMPT builds"). I traced the hang into -> cpufreq_suspend() -> cpufreq_stop_governor() -> cpufreq_dbs_governor_stop() -> gov_clear_update_util() -> synchronize_sched() -> synchronize_rcu() Only PREEMPT=y is affected for obvious reasons. The problem is limited to PIC machines since they mask off interrupts in i8259A_shutdown() (syscore_ops.shutdown() registered from device_initcall()). I reported this long ago but no better fix has surfaced, hence sending out my initial workaround which I've been carrying around ever since. I just move cpufreq_core_init() to late_initcall() so the syscore_ops get registered in the oppsite order and thus the .shutdown() hooks get executed in the opposite order as well. Not 100% convinced this is safe (especially moving the cpufreq_global_kobject creation to late_initcall()) but I've not had any problems with it at least. Here's the resulting change in initcall_debug: + PM: Calling cpufreq_suspend+0x0/0x100 PM: Calling mce_syscore_shutdown+0x0/0x10 PM: Calling i8259A_shutdown+0x0/0x10 - PM: Calling cpufreq_suspend+0x0/0x100 + reboot: Restarting system + reboot: machine restart Cc: stable(a)vger.kernel.org Cc: Paul E.

[PATCH] ch: Make it again possible to open a ch device two or more times

[PATCH 4.19] nvme: Assign subsys instance from first ctrl

by Keith Busch

commit 733e4b69d508d03c20adfdcf4bd27abc60fae9cc upstream The namespace disk names must be unique for the lifetime of the subsystem. This was accomplished by using their parent subsystems' instances which were allocated independently from the controllers connected to that subsystem. This allowed name prefixes assigned to namespaces to match a controller from an unrelated subsystem, and has created confusion among users examining device nodes. Ensure a namespace's subsystem instance never clashes with a controller instance of another subsystem by transferring the instance ownership to the parent subsystem from the first controller discovered in that subsystem.

[PATCH 4.14.y] xfs: clear sb->s_fs_info on mount failure

by Ajay Kaher

From: Dave Chinner <dchinner(a)redhat.com> commit c9fbd7bbc23dbdd73364be4d045e5d3612cf6e82 upstream. We recently had an oops reported on a 4.14 kernel in xfs_reclaim_inodes_count() where sb->s_fs_info pointed to garbage and so the m_perag_tree lookup walked into lala land. Essentially, the machine was under memory pressure when the mount was being run, xfs_fs_fill_super() failed after allocating the xfs_mount and attaching it to sb->s_fs_info. It then cleaned up and freed the xfs_mount, but the sb->s_fs_info field still pointed to the freed memory. Hence when the superblock shrinker then ran it fell off the bad pointer. With the superblock shrinker problem fixed at teh VFS level, this stale s_fs_info pointer is still a problem - we use it unconditionally in ->put_super when the superblock is being torn down, and hence we can still trip over it after a ->fill_super call failure. Hence we need to clear s_fs_info if xfs-fs_fill_super() fails, and we need to check if it's valid in the places it can potentially be dereferenced after a ->fill_super failure.

[PATCH 1/3] USB: usb-skeleton: fix NULL-deref on disconnect

by Johan Hovold

The driver was using its struct usb_interface pointer as an inverted disconnected flag and was setting it to NULL before making sure all completion handlers had run. This could lead to NULL-pointer dereferences in the dev_err() statements in the completion handlers which relies on said pointer. Fix this by using a dedicated disconnected flag. Note that this is also addresses a NULL-pointer dereference at release() and a struct usb_interface reference leak introduced by a recent runtime PM fix, which depends on and should have been submitted together with this patch.

[PATCH 3/5] USB: ldusb: fix NULL-derefs on driver unbind

by Johan Hovold

The driver was using its struct usb_interface pointer as an inverted disconnected flag, but was setting it to NULL before making sure all completion handlers had run. This could lead to a NULL-pointer dereference in a number of dev_dbg, dev_warn and dev_err statements in the completion handlers which relies on said pointer. Fix this by unconditionally stopping all I/O and preventing resubmissions by poisoning the interrupt URBs at disconnect and using a dedicated disconnected flag. This also makes sure that all I/O has completed by the time the disconnect callback returns.

[PATCH] staging: rtl8723bs: hal: Fix memcpy calls

by Denis Efremov

memcpy() in phy_ConfigBBWithParaFile() and PHY_ConfigRFWithParaFile() is called with "src == NULL && len == 0". This is an undefined behavior. Moreover this if pre-condition "pBufLen && (*pBufLen == 0) && !pBuf" is constantly false because it is a nested if in the else brach, i.e., "if (cond) { ... } else { if (cond) {...} }". This patch alters the if condition to check "pBufLen && pBuf" pointers are not NULL.

[PATCH 4.4, 4.9, 4.14, 4.19] nl80211: validate beacon head

From: Johannes Berg <johannes.berg(a)intel.com> Commit 8a3347aa110c76a7f87771999aed491d1d8779a8 upstream. We currently don't validate the beacon head, i.e. the header, fixed part and elements that are to go in front of the TIM element. This means that the variable elements there can be malformed, e.g. have a length exceeding the buffer size, but most downstream code from this assumes that this has already been checked. Add the necessary checks to the netlink policy.

[PATCH 1/6] USB: iowarrior: fix use-after-free on disconnect

by Johan Hovold

A recent fix addressing a deadlock on disconnect introduced a new bug by moving the present flag out of the critical section protected by the driver-data mutex. This could lead to a racing release() freeing the driver data before disconnect() is done with it. Due to insufficient locking a related use-after-free could be triggered also before the above mentioned commit. Specifically, the driver needs to hold the driver-data mutex also while checking the opened flag at disconnect().

[PATCH] coresight: etm4x: Use explicit barriers on enable/disable

by Mathieu Poirier

From: Andrew Murray <andrew.murray(a)arm.com> commit 1004ce4c255fc3eb3ad9145ddd53547d1b7ce327 upstream Synchronization is recommended before disabling the trace registers to prevent any start or stop points being speculative at the point of disabling the unit (section 7.3.77 of ARM IHI 0064D). Synchronization is also recommended after programming the trace registers to ensure all updates are committed prior to normal code resuming (section 4.3.7 of ARM IHI 0064D). Let's ensure these syncronization points are present in the code and clearly commented. Note that we could rely on the barriers in CS_LOCK and coresight_disclaim_device_unlocked or the context switch to user space - however coresight may be of use in the kernel. On armv8 the mb macro is defined as dsb(sy) - Given that the etm4x is only used on armv8 let's directly use dsb(sy) instead of mb(). This removes some ambiguity and makes it easier to correlate the code with the TRM.

[PATCH for-stable-v4.19 00/16] arm64 spec mitigation backports

by Ard Biesheuvel

This is a backport to v4.19 of the arm64 patches that exists in mainline to support CPUs that implement the SSBS capability, which gives the OS and user space control over whether Speculative Store Bypass is permitted in certain contexts. This gives a substantial performance boost on hardware that implements it. At the same time, this series backports arm64 support for reporting of vulnerabilities via syfs. This is covered by the same series since it produces a much cleaner backport, where none of the patches required any changes beyond some manual mangling of the context to make them apply. Build tested using a fair number of randconfig builds. Boot tested under KVM and on ThunderX2.

When freeing the queues, we check for possible escalation interrupts and free them also. But when a XIVE VP is disabled, the underlying XIVE ENDs also are disabled in OPAL. When an END (Event Notification Descriptor) is disabled, its ESB pages (ESn and ESe) are disabled and loads return all 1s. Which means that any access on the ESB page of the escalation interrupt will return invalid values. When an interrupt is freed, the shutdown handler computes a 'saved_p' field from the value returned by a load in xive_do_source_set_mask(). This value is incorrect for escalation interrupts for the reason described above. This has no impact on Linux/KVM today because we don't make use of it but we will introduce in future changes a xive_get_irqchip_state() handler. This handler will use the 'saved_p' field to return the state of an interrupt and 'saved_p' being incorrect, softlockup will occur. Fix the vCPU cleanup sequence by first freeing the escalation interrupts if any, then disable the XIVE VP and last free the queues.

However, It may erroneously enable the interrupts if the interrupts are disabled before entering the handle_exception. For example, one of the WARN_ON() condition is satisfied in the scheduling where the interrupt is disabled and rq.lock is locked. The WARN_ON will trigger a break exception and the handle_exception function will enable the interrupts before entering do_trap_break function. During the procedure, if a timer interrupt is pending, it will be taken when interrupts are enabled. In this case, it may cause a deadlock problem if the rq.lock is locked again in the timer ISR. Hence, the handle_exception() can only enable interrupts when the state of sstatus.SPIE is 1. This patch is tested on HiFive Unleashed board.

[PATCH v2 5/6] rpmsg: glink: Don't send pending rx_done during remove

by Bjorn Andersson

Attempting to transmit rx_done messages after the GLINK instance is being torn down will cause use after free and memory leaks. So cancel the intent_work and free up the pending intents. With this there are no concurrent accessors of the channel left during qcom_glink_native_remove() and there is therefor no need to hold the spinlock during this operation - which would prohibit the use of cancel_work_sync() in the release function. So remove this.

The wrong values will be shown for the first interval on the second and subsequent repetitions. Without the fix: # perf stat -r 3 -I 2000 -e faults -e sched:sched_switch -a sleep 5 2.000282489 53 faults 2.000282489 513 sched:sched_switch 4.005478208 3,721 faults 4.005478208 2,666 sched:sched_switch 5.025470933 395 faults 5.025470933 1,307 sched:sched_switch 2.009602825 1,84,46,74,40,73,70,95,47,520 faults <------ 2.009602825 1,84,46,74,40,73,70,95,49,568 sched:sched_switch <------ 4.019612206 4,730 faults 4.019612206 2,746 sched:sched_switch 5.039615484 3,953 faults 5.039615484 1,496 sched:sched_switch 2.000274620 1,84,46,74,40,73,70,95,47,520 faults <------ 2.000274620 1,84,46,74,40,73,70,95,47,520 sched:sched_switch <------ 4.000480342 4,282 faults 4.000480342 2,303 sched:sched_switch 5.000916811 1,322 faults 5.000916811 1,064 sched:sched_switch # prev_raw_counts is allocated when using intervals. This is used when calculating the difference in the counts of events when using interval. The current counts are stored in prev_raw_counts to calculate the differences in the next iteration. On the first interval of the second and subsequent repetitions, prev_raw_counts would be the values stored in the last interval of the previous repetitions, while the current counts will only be for the first interval of the current repetition. Hence there is a possibility of events showing up as big number. Fix this by resetting prev_raw_counts whenever perf stat repeats the command.
