As the new x86 CPU bootup printout format code maintainer, I am taking immediate action to improve and clean (and thus indulge my OCD) the reporting of the cores when coming up online. Fix padding to a right-hand alignment, cleanup code and bind reporting width to the max number of supported CPUs on the system, like this: [ 0.074509] smpboot: Booting Node 0, Processors: #1 #2 #3 #4 #5 #6 #7 OK [ 0.644008] smpboot: Booting Node 1, Processors: #8 #9 #10 #11 #12 #13 #14 #15 OK [ 1.245006] smpboot: Booting Node 2, Processors: #16 #17 #18 #19 #20 #21 #22 #23 OK [ 1.864005] smpboot: Booting Node 3, Processors: #24 #25 #26 #27 #28 #29 #30 #31 OK [ 2.489005] smpboot: Booting Node 4, Processors: #32 #33 #34 #35 #36 #37 #38 #39 OK [ 3.093005] smpboot: Booting Node 5, Processors: #40 #41 #42 #43 #44 #45 #46 #47 OK [ 3.698005] smpboot: Booting Node 6, Processors: #48 #49 #50 #51 #52 #53 #54 #55 OK [ 4.304005] smpboot: Booting Node 7, Processors: #56 #57 #58 #59 #60 #61 #62 #63 OK [ 4.961413] Brought up 64 CPUs and this: [ 0.072367] smpboot: Booting Node 0, Processors: #1 #2 #3 #4 #5 #6 #7 OK [ 0.686329] Brought up 8 CPUs Signed-off-by: Borislav Petkov <[email protected]> Cc: Libin <[email protected]> Cc: [email protected] Cc: [email protected] Cc: [email protected] Cc: [email protected] Link: http://lkml.kernel.org/r/[email protected] Signed-off-by: Ingo Molnar <[email protected]>

In case of SDIO/PCIe, after receiving 50 packets in Rx queue we stop processing interrupts till packets pending fall below low threshold i.e 20. We don't have similar logic for USB, so if host platform is slow, we would hit a case where firmware keeps on pushing packets at high speed than driver/kernel can process. We will stop submitting URBs for Rx data when pending packet count reaches high threshold and restart them when enough packets are consumed to solve the problem.

For example it should be perfectly valid to attach an inactive device to a powered PM domain. The pm_genpd_dev_need_restore() API allow us to update the need_restore flag to somewhat cope with such scenarios. Typically that should have been done from drivers/buses ->probe() since it's those that put the requirements on the value of the need_restore flag. Until recently, the Exynos SOCs were the only user of the pm_genpd_dev_need_restore() API, though invoking it from a centralized location while adding devices to their PM domains. Due to that Exynos now have swithed to the generic OF-based PM domain look-up, it's no longer possible to invoke the API from a centralized location. The reason is because devices are now added to their PM domains during the probe sequence. Commit "ARM: exynos: Move to generic PM domain DT bindings" did the switch for Exynos to the generic OF-based PM domain look-up, but it also removed the call to pm_genpd_dev_need_restore(). This caused a regression for some of the Exynos drivers. To handle things more properly in the generic PM domain, let's change the default initial value of the need_restore flag to reflect that the state is unknown. As soon as some of the runtime PM callbacks gets invoked, update the initial value accordingly. Moreover, since the generic PM domain is verifying that all devices are both runtime PM enabled and suspended, using pm_runtime_suspended() while pm_genpd_poweroff() is invoked from the scheduled work, we can be sure of that the PM domain won't be powering off while having active devices. Do note that, the generic PM domain can still only know about active devices which has been activated through invoking its runtime PM resume callback. In other words, buses/drivers using pm_runtime_set_active() during ->probe() will still suffer from a race condition, potentially probing a device without having its PM domain being powered. That issue will have to be solved using a different approach. This a log from the boot regression for Exynos5, which is being fixed in this patch. ------------[ cut here ]------------ WARNING: CPU: 0 PID: 308 at ../drivers/clk/clk.c:851 clk_disable+0x24/0x30() Modules linked in: CPU: 0 PID: 308 Comm: kworker/0:1 Not tainted 3.18.0-rc3-00569-gbd9449f-dirty #10 Workqueue: pm pm_runtime_work [<c0013c64>] (unwind_backtrace) from [<c0010dec>] (show_stack+0x10/0x14) [<c0010dec>] (show_stack) from [<c03ee4cc>] (dump_stack+0x70/0xbc) [<c03ee4cc>] (dump_stack) from [<c0020d34>] (warn_slowpath_common+0x64/0x88) [<c0020d34>] (warn_slowpath_common) from [<c0020d74>] (warn_slowpath_null+0x1c/0x24) [<c0020d74>] (warn_slowpath_null) from [<c03107b0>] (clk_disable+0x24/0x30) [<c03107b0>] (clk_disable) from [<c02cc834>] (gsc_runtime_suspend+0x128/0x160) [<c02cc834>] (gsc_runtime_suspend) from [<c0249024>] (pm_generic_runtime_suspend+0x2c/0x38) [<c0249024>] (pm_generic_runtime_suspend) from [<c024f44c>] (pm_genpd_default_save_state+0x2c/0x8c) [<c024f44c>] (pm_genpd_default_save_state) from [<c024ff2c>] (pm_genpd_poweroff+0x224/0x3ec) [<c024ff2c>] (pm_genpd_poweroff) from [<c02501b4>] (pm_genpd_runtime_suspend+0x9c/0xcc) [<c02501b4>] (pm_genpd_runtime_suspend) from [<c024a4f8>] (__rpm_callback+0x2c/0x60) [<c024a4f8>] (__rpm_callback) from [<c024a54c>] (rpm_callback+0x20/0x74) [<c024a54c>] (rpm_callback) from [<c024a930>] (rpm_suspend+0xd4/0x43c) [<c024a930>] (rpm_suspend) from [<c024bbcc>] (pm_runtime_work+0x80/0x90) [<c024bbcc>] (pm_runtime_work) from [<c0032a9c>] (process_one_work+0x12c/0x314) [<c0032a9c>] (process_one_work) from [<c0032cf4>] (worker_thread+0x3c/0x4b0) [<c0032cf4>] (worker_thread) from [<c003747c>] (kthread+0xcc/0xe8) [<c003747c>] (kthread) from [<c000e738>] (ret_from_fork+0x14/0x3c) ---[ end trace 40cd58bcd6988f12 ]--- Fixes: a4a8c2c4962bb655 (ARM: exynos: Move to generic PM domain DT bindings) Reported-and-tested0by: Sylwester Nawrocki <[email protected]> Reviewed-by: Sylwester Nawrocki <[email protected]> Reviewed-by: Kevin Hilman <[email protected]> Signed-off-by: Ulf Hansson <[email protected]> Signed-off-by: Rafael J.

For historical reasons we also align payload to to 4 bytes boundary, but such alignment is not needed on modern H/W. Patch fixes skb_under_panic problems reported from time to time: https://bugzilla.kernel.org/show_bug.cgi?id=84911 https://bugzilla.kernel.org/show_bug.cgi?id=72471 http://marc.info/?l=linux-wireless&m=139108549530402&w=2 https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1087591 Panic happened because we eat 4 bytes of skb headroom on each (re)transmission when sending frame without the payload and the header length not being multiple of 4 (i.e. QoS header has 26 bytes). On such case because paylad_aling=2 is bigger than header_align=0 we increase header_align by 4 bytes. To prevent that we could change the check to: if (payload_length && payload_align > header_align) header_align += 4; but not aligning payload at all is more effective and alignment is not really needed by H/W (that has been tested on OpenWrt project for few years now).

This patch works around the problem by moving the allocation outside the lock. The bug was revealed by the recent change in net/core/filter.c, as it allocates via vmalloc() instead of kmalloc() now.

Fix this by restricting the CPU selections to respective multiplatform config, which now becomes a subset of the possible Integrator configurations, or alternatively the non-multiplatform config plus ARCH_INTEGRATOR, i.e.: if (!ARCH_MULTIPLATFORM || ARCH_MULTI_Vx) && (ARCH_INTEGRATOR || ARCH_FOO ...) Since the Integrator has been converted to multiplatform, this will often take the short form: if (ARCH_MULTI_Vx && ARCH_INTEGRATOR) If no other non-multiplatform platforms are elegible.

If there is contention on the lock, this violates the rules for preemption-disabled regions.

We normally use one cpu per RX queue (IRQ smp_affinity being properly set), so remembering on socket structure which cpu delivered last packet is enough to solve the problem.

But when it comes to dynamically allocated ftrace_ops, where they may be freed, on a CONFIG_PREEMPT kernel there's no way to know when it is safe to free the trampoline. If a task was preempted while executing on the trampoline, there's currently no way to know when it will be off that trampoline. But this is not true when it comes to !CONFIG_PREEMPT. The current method of calling schedule_on_each_cpu() will force tasks off the trampoline, becaues they can not schedule while on it (kernel preemption is not configured).

Introduce dm_internal_suspend_noflush() variant that actually calls the mapped_device's target callbacks -- otherwise target-specific hooks are avoided (e.g. dm-thin's thin_presuspend and thin_postsuspend). Common code between dm_internal_{suspend_noflush,resume} and dm_{suspend,resume} was factored out as __dm_{suspend,resume}. Update dm_internal_{suspend_noflush,resume} to always take and release the mapped_device's suspend_lock. Also update dm_{suspend,resume} to be aware of potential for DM_INTERNAL_SUSPEND_FLAG to be set and respond accordingly by interruptibly waiting for the DM_INTERNAL_SUSPEND_FLAG to be cleared. Add lockdep annotation to dm_suspend() and dm_resume(). Also add DM_INTERNAL_SUSPEND_FLAG to status report. This new DM_INTERNAL_SUSPEND_FLAG state is being tracked/reported to assist with debugging (e.g. 'dmsetup info' will report an internally suspended device accordingly). The existing DM_SUSPEND_FLAG remains unchanged. DM_INTERNAL_SUSPEND_FLAG is set by dm_internal_suspend_noflush() and cleared by dm_internal_resume(). Both DM_SUSPEND_FLAG and DM_INTERNAL_SUSPEND_FLAG may be set if a device was already suspended when dm_internal_suspend_noflush() was called -- this can be thought of as a "nested suspend". A "nested suspend" can with legacy userspace dm-thin code that might suspend all active thin volumes before suspending the pool for resize. But otherwise, in the normal dm-thin-pool suspend case moving forward: the thin-pool will have DM_SUSPEND_FLAG set and all active thins from that thin-pool will have DM_INTERNAL_SUSPEND_FLAG set.

Systems that declare ACPI operation regions may reference them at any time, including during kernel initialisation. These accesses will fail unless the ACPI IPMI driver is present, and undesirable system behaviour may result. Set the default to Y in order to encourage distributions and users to configure kernels to avoid awkward surprises.

Initially the plan was to add a new command to handle the case of 'create new element if it didn't exist', but 'flags' style looks cleaner and overall diff is much smaller (more code reused), so add 'flags' attribute to BPF_MAP_UPDATE_ELEM command with the following meaning: #define BPF_ANY 0 /* create new element or update existing */ #define BPF_NOEXIST 1 /* create new element if it didn't exist */ #define BPF_EXIST 2 /* update existing element */ bpf_update_elem(fd, key, value, BPF_NOEXIST) call can fail with EEXIST if element already exists. bpf_update_elem(fd, key, value, BPF_EXIST) can fail with ENOENT if element doesn't exist.

Now, as DCB TCs may have changed the PF driver tries to reconfigure the TC configuration of the VSIs it manages. As part of this process it disables the VSI queues but the Tx queue disable will not complete as the port's Tx has been suspended. So, waiting for Tx queues to go to disable state in this flow may lead to detection of Tx queue disable timeout errors. Hence, this patch adds a new PF state so that if a port's Tx is in suspended state the Tx queue disable flow would just put the request for the queue to be disabled and return without waiting for the queue to be actually disabled. Once the VSI(s) TC reconfiguration has been done and driver has called firmware AQC "Resume PF Traffic" the driver checks the Tx queues requested to be disabled are actually disabled before re-enabling them again.

We learned that it was possible for the core networking code to call
visornic_xmit() within ISR context, resulting in the need for us to
use spin_lock_irqsave() / spin_lock_irqrestore() to lock accesses to our
virtual device channels.
Without the correct locking added in this patch, random hangs would occur
on typical kernels while stressing the netork. When using a kernel with
CONFIG_DEBUG_SPINLOCK=y, a stackdump would occur at the time of the hang
reporting:
BUG: spinlock recursion on CPU#0, vnic_incoming/<pid>
(see below for more details)
We considered the possibility of adding a protocol between a visordriver
and visorbus where the visordriver could specify which type of locking it
required for its virtual device channels (essentially indicating whether
or not it was possible for the channel to be accessed in ISR context), but
decided this extra complexity was NOT needed, and that channel queues
should always be accessed with the most-stringent locking. So that is
what is implemented in this commit.
Below is an example stackdump illustrating the spinlock recursion that is
fixed by this commit. Note that we are first in virtnic_rx() writing to
the device channel when an APIC timer interrupt occurs. Within the core
networking code, net_rx_action() calls process_backlog(), which eventually
lands up back up in virtnic_xmit() in the code attempting to also write to
the device channel.

GIT 78add8a6901c143cfb091fae54e793af8a48ee41 commit e323d56eb06b266b77c2b430cb5f1977ba549e03 Author: Krzysztof Kozlowski <[email protected]> Date: Fri Jun 12 10:53:25 2015 +0900 clk: exynos4: Fix wrong clock for Exynos4x12 ADC The TSADC gate clock was used in Exynos4x12 DTSI for exynos-adc driver. However TSADC is present only on Exynos4210 so on Trats2 board (with Exynos4412 SoC) the exynos-adc driver could not be probed: ERROR: could not get clock /adc@126C0000:adc(0) exynos-adc 126c0000.adc: failed getting clock, err = -2 exynos-adc: probe of 126c0000.adc failed with error -2 Instead on Exynos4x12 SoCs the main clock used by Analog to Digital Converter is located in different register and it is named in datasheet as PCLK_ADC. Regardless of the name the purpose of this PCLK_ADC clock is the same as purpose of TSADC from Exynos4210. The patch adds gate clock for Exynos4x12 using the proper register so backward compatibility is preserved. This fixes the probe of exynos-adc driver on Exynos4x12 boards and allows accessing sensors connected to it on Trats2 board (ntc,ncp15wb473 AP and battery thermistors).

Convert drivers to use the genirq interfaces directly, so we can kill off set_irq_flags. The translation of flags is as follows: IRQF_VALID -> !IRQ_NOREQUEST IRQF_PROBE -> !IRQ_NOPROBE IRQF_NOAUTOEN -> IRQ_NOAUTOEN For IRQs managed by an irqdomain, the irqdomain core code handles clearing and setting IRQ_NOREQUEST already, so there is no need to do this in .map() functions and we can simply remove the set_irq_flags calls. Some users also modify IRQ_NOPROBE and this has been maintained although it is not clear that is really needed. There appears to be a great deal of blind copy and paste of this code.

To encourage clk providers to move away from the consumer APIs, add a provider API to set the min/max rate of a clock. The assumption is that this is done before the clock can be requested via clk_get() and that the clock rate is already within the boundaries of the min/max that's configured.

But since we can end up in the fbdev code simply due to the console unblanking that's done unconditionally just removing our panic handler isn't enough. We need to block all fbdev callbacks when oopsing. There was already one in the blank handler, but it failed silently. That makes it impossible for drivers (like i915) who subclass these functions to figure this out. Instead consistently return -EBUSY so that everyone knows that we really don't want to be bothered right now. This also allows us to remove a pile of FIXMEs from the i915 fbdev code (since due to the failure code they now won't attempt to grab dangerous locks any more).

This is a sanity check to verify if we were indeed throttled/unthrottled after receiving OCC_THROTTLE notification. We cannot call *throttle_check() directly from the notification handler because we could be handling chip1's notification in chip2. So initiate an smp_call to execute *throttle_check().

Wysocki <[email protected]> Date: Sun Jul 26 02:07:47 2015 +0200 cpufreq: Avoid attempts to create duplicate symbolic links After commit 87549141d516 (cpufreq: Stop migrating sysfs files on hotplug) there is a problem with CPUs that share cpufreq policy objects with other CPUs and are initially offline. Say CPU1 shares a policy with CPU0 which is online and is registered first. As part of the registration process, cpufreq_add_dev() is called for it. It creates the policy object and a symbolic link to it from the CPU1's sysfs directory. If CPU1 is registered subsequently and it is offline at that time, cpufreq_add_dev() will attempt to create a symbolic link to the policy object for it, but that link is present already, so a warning about that will be triggered. To avoid that warning, make cpufreq use an additional CPU mask containing related CPUs that are actually present for each policy object. That mask is initialized when the policy object is populated after its creation (for the first online CPU using it) and it includes CPUs from the "policy CPUs" mask returned by the cpufreq driver's ->init() callback that are physically present at that time. Symbolic links to the policy are created only for the CPUs in that mask. If cpufreq_add_dev() is invoked for an offline CPU, it checks the new mask and only creates the symlink if the CPU was not in it (the CPU is added to the mask at the same time). In turn, cpufreq_remove_dev() drops the given CPU from the new mask, removes its symlink to the policy object and returns, unless it is the CPU owning the policy object. In that case, the policy object is moved to a new CPU's sysfs directory or deleted if the CPU being removed was the last user of the policy. While at it, notice that cpufreq_remove_dev() can't fail, because its return value is ignored, so make it ignore return values from __cpufreq_remove_dev_prepare() and __cpufreq_remove_dev_finish() and prevent these functions from aborting on errors returned by __cpufreq_governor(). Also drop the now unused sif argument from them. Fixes: 87549141d516 (cpufreq: Stop migrating sysfs files on hotplug) Signed-off-by: Rafael J.

Decrement the additional parent reference when a watch is reused, already having a reference to the parent. audit_find_parent() gets a reference to the parent, if the parent is already known. This additional parental reference is not needed if the watch is subsequently found by audit_add_to_parent(), and consumed if the watch does not already exist, so we need to put the parent if the watch is found, and do nothing if this new watch is added to the parent. If the parent wasn't already known, it is created with a refcount of 1 and added to the audit_watch_group, then incremented by one to be subsequently consumed by the newly created watch in audit_add_to_parent(). The rule points to the watch, not to the parent, so the rule's refcount gets bumped, not the parent's.

Let's take the chance to establish common conventions throughout all controllers. This patch defines CGROUP_WEIGHT_MIN/DFL/MAX to be used on all weight based control knobs and documents the conventions that controllers should follow on the unified hierarchy. Except for io.weight knob, all existing unified hierarchy knobs are already compliant. A follow-up patch will update io.weight. v2: Added descriptions of min, low and high knobs.

It could cause bugs because if some function doesn't set this field autoconfig could return the same endpoint more than one time. To help to avoid such bugs this patch adds claimed flag to struct usb_ep, and encapsulates endpoint claiming mechanism inside usb_ep_autoconfig_ss() and usb_ep_autoconfig_reset(), so now usb functions don't need to perform any additional actions to mark endpoint obtained from autoconfig as claimed.

If we ask for more reserved credits than 1/2 of maximum transaction size, or if total number of credits exceeds the maximum transaction size per operation (which is currently only possible with the former) we will spin forever in start_this_handle(). Fix this by adding this limitation at the start of start_this_handle(). This patch also removes the credit limitation 1/2 of maximum transaction size, since we really only want to limit the number of reserved credits. There is not much point to limit the credits if there is still space in the journal. This accidentally also fixes the online resize, where due to the limitation of the journal credits we're unable to grow file systems with 1k block size and size between 16M and 32M.

Driver was freeing its internal description of battery through pointers stored in power_supply structure. However, because the core owns the power supply instance, after calling power_supply_unregister() this memory is freed and the driver cannot access these members. Fix this by storing the pointer to internal description of battery in a local variable before calling power_supply_unregister(), so the pointer remains valid.

This quirk was used by the wireless receiver to prevent any devices from being created during the initial probe (defering it instead until we got a tablet connection event in 'wacom_wireless_work'). This quirk is not necessary now that a device_type is associated with each device. Any input device allocated by 'wacom_allocate_inputs' which is not necessary for a particular device is freed in 'wacom_register_inputs'. In particular, none of the wireless receivers devices have the pen, pad, or touch device types set so the same effect is achieved without the need to be explicit. We now return early in wacom_retrieve_hid_descriptor for wireless devices (to prevent the device_type from being overridden) but since we ignore the HID descriptor for the wireless reciever anyway, this is not an issue.

The clock domain part is very similar to the CPG/MSTP Clock Domain, which is used on shmobile SoCs without device power domains, except for the way how clocks suitable for power management are selected: - The former uses the first clock tied to the device through the NULL con_id, which is a relic from the legacy pm_clk_notifier-based method in drivers/sh/pm_runtime.c, - The latter looks for suitable clocks in DT, which is more future-proof. All platforms using this driver are now supported in DT-based ARM multi-platform builds only, hence switch to using the CPG/MSTP Clock Domain helpers.

Hence do not enable it when running a multi-platform kernel with genpd support on R-Car or RZ. The CPG/MSTP Clock Domain driver will take care of PM runtime management of the module clocks. Now most multi-platform ARM shmobile platforms (SH-Mobile, R-Mobile, R-Car, RZ) use DT-based PM Domains to take care of PM runtime management of the module clocks, simplify the platform logic by replacing the explicit SoC checks by a single check for the presence of MSTP clocks in DT. Backwards-compatiblity with old DTs (mainly for R-Car Gen2) is provided by checking for the presence of a "#power-domain-cells" property in DT. The default PM Domain is still needed for: - backwards-compatibility with old DTs that lack PM Domain properties, - the CONFIG_PM=n case, - legacy (non-DT) ARM/shmobile platforms without genpd support (r8a7778, r8a7779), - legacy SuperH.

We have to adjust that value during the STP synchronization and make sure that code that accesses the epoch won't get interrupted in between (via disabling preemption).

Splitting the system memory into nodes replicates the memory management structures for each node. Particularly each node has its own "mm locks" and its own "kswapd" task. For large systems, under certain conditions, this results in improved system performance and/or latency based on reduced pressure on the mm locks and the kswapd tasks. NUMA emulation distributes CPUs to nodes while respecting the original machine topology information. This is done by trying to avoid to separate CPUs which reside on the same book or even on the same MC. Because the current Linux scheduler code requires a stable cpu to node mapping, cores are pinned to nodes when the first CPU thread is set online. This patch is based on the initial implementation from Philipp Hachtmann.

This would otherwise have been set by ip_output or ip6_output so set skb->protocol prior to calling the lwtunnel encap function.

Otherwise, undoing the copy and map operations is tricky. This fixes a use-after-free: if allocating the fraglist failed, the copy and map operations that had been set up were still executed, writing over the data area of a freed skb.

The breadcrumbs are about to be used from within IRQ context sections (e.g. nouveau signals a fence from an interrupt handler causing us to submit a new request) and/or from bottom-half tasklets (i.e. intel_lrc_irq_handler), therefore we need to employ the irqsafe spinlock variants. For example, deferring the request submission to the intel_lrc_irq_handler generates this trace: [ 66.388639] ================================= [ 66.388650] [ INFO: inconsistent lock state ] [ 66.388663] 4.9.0-rc2+ torvalds#56 Not tainted [ 66.388672] --------------------------------- [ 66.388682] inconsistent {SOFTIRQ-ON-W} -> {IN-SOFTIRQ-W} usage.
