2013-06-24netfilter: ctnetlink: send event when conntrack label was modifiedFlorian Westphal
commit 0ceabd83875b72a29f33db4ab703d6ba40ea4c58 (netfilter: ctnetlink: deliver labels to userspace) sets the event bit when we raced with another packet, instead of raising the event bit when the label bit is set for the first time. commit 9b21f6a90924dfe8e5e686c314ddb441fb06501e (netfilter: ctnetlink: allow userspace to modify labels) forgot to update the event mask in the "conntrack already exists" case. Both issues result in CTA_LABELS attribute not getting included in the conntrack event. Signed-off-by: Florian Westphal <fw@strlen.de> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

2013-06-24ACPI / dock / PCI: Synchronous handling of dock events for PCI devicesRafael J. Wysocki
The interactions between the ACPI dock driver and the ACPI-based PCI hotplug (acpiphp) are currently problematic because of ordering issues during hot-remove operations. First of all, the current ACPI glue code expects that physical devices will always be deleted before deleting the companion ACPI device objects. Otherwise, acpi_unbind_one() will fail with a warning message printed to the kernel log, for example: [ 185.026073] usb usb5: Oops, 'acpi_handle' corrupt [ 185.035150] pci 0000:1b:00.0: Oops, 'acpi_handle' corrupt [ 185.035515] pci 0000:18:02.0: Oops, 'acpi_handle' corrupt [ 180.013656] port1: Oops, 'acpi_handle' corrupt This means, in particular, that struct pci_dev objects have to be deleted before the struct acpi_device objects they are "glued" with. Now, the following happens the during the undocking of an ACPI-based dock station: 1) hotplug_dock_devices() invokes registered hotplug callbacks to destroy physical devices associated with the ACPI device objects depending on the dock station. It calls dd->ops->handler() for each of those device objects. 2) For PCI devices dd->ops->handler() points to handle_hotplug_event_func() that queues up a separate work item to execute _handle_hotplug_event_func() for the given device and returns immediately. That work item will be executed later. 3) hotplug_dock_devices() calls dock_remove_acpi_device() for each device depending on the dock station. This runs acpi_bus_trim() for each of them, which causes the underlying ACPI device object to be destroyed, but the work items queued up by handle_hotplug_event_func() haven't been started yet. 4) _handle_hotplug_event_func() queued up in step 2) are executed and cause the above failure to happen, because the PCI devices they handle do not have the companion ACPI device objects any more (those objects have been deleted in step 3). The possible breakage doesn't end here, though, because hotplug_dock_devices() may return before at least some of the _handle_hotplug_event_func() work items spawned by it have a chance to complete and then undock() will cause _DCK to be evaluated and that will cause the devices handled by the _handle_hotplug_event_func() to go away possibly while they are being accessed. This means that dd->ops->handler() for PCI devices should not point to handle_hotplug_event_func(). Instead, it should point to a function that will do the work of _handle_hotplug_event_func() synchronously. For this reason, introduce such a function, hotplug_event_func(), and modity acpiphp_dock_ops to point to it as the handler. Unfortunately, however, this is not sufficient, because if the dock code were not changed further, hotplug_event_func() would now deadlock with hotplug_dock_devices() that called it, since it would run unregister_hotplug_dock_device() which in turn would attempt to acquire the dock station's hp_lock mutex already acquired by hotplug_dock_devices(). To resolve that deadlock use the observation that unregister_hotplug_dock_device() won't need to acquire hp_lock if PCI bridges the devices on the dock station depend on are prevented from being removed prematurely while the first loop in hotplug_dock_devices() is in progress. To make that possible, introduce a mechanism by which the callers of register_hotplug_dock_device() can provide "init" and "release" routines that will be executed, respectively, during the addition and removal of the physical device object associated with the given ACPI device handle. Make acpiphp use two new functions, acpiphp_dock_init() and acpiphp_dock_release(), that call get_bridge() and put_bridge(), respectively, on the acpiphp bridge holding the given device, for this purpose. In addition to that, remove the dock station's list of "hotplug devices" and make the dock code always walk the whole list of "dependent devices" instead in such a way that the loops in hotplug_dock_devices() and dock_event() (replacing the loops over "hotplug devices") will take references to the list entries that register_hotplug_dock_device() has been called for. That prevents the "release" routines associated with those entries from being called while the given entry is being processed and for PCI devices this means that their bridges won't be removed (by a concurrent thread) while hotplug_event_func() handling them is being executed. This change is based on two earlier patches from Jiang Liu. References: https://bugzilla.kernel.org/show_bug.cgi?id=59501 Reported-and-tested-by: Alexander E.

2013-06-23ARM: mvebu: fix length of ethernet registers in mv78260 dtsiEzequiel Garcia
The length of the registers area for the Marvell 370/XP Ethernet controller was incorrect in the .dtsi: 0x2500, while it should have been 0x4000. This problem wasn't noticed because there used to be a static mapping for all the MMIO register region set up by ->map_io(). The register length was fixed in all the other device tree files, except from the armada-xp-mv78260.dtsi, in the following commit: commit cf8088c5cac6ce20d914b9131533844b9291a054 Author: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Date: Tue May 21 12:33:27 2013 +0200 arm: mvebu: fix length of Ethernet registers area in .dtsi This commit fixes a kernel panic in mvneta_probe(), when the kernel tries to access the unmapped registers: [ 163.639092] mvneta d0070000.ethernet eth0: mac: 6e:3c:4f:87:17:2e [ 163.646962] mvneta d0074000.ethernet eth1: mac: 6a:04:4e:6f:f5:ef [ 163.654853] mvneta d0030000.ethernet eth2: mac: 2a:99:19:19:fc:4c [ 163.661258] Unable to handle kernel paging request at virtual address f011bcf0 [ 163.668523] pgd = c0004000 [ 163.671237] [f011bcf0] *pgd=2f006811, *pte=00000000, *ppte=00000000 [ 163.677565] Internal error: Oops: 807 [#1] SMP ARM [ 163.682370] CPU: 0 PID: 1 Comm: swapper/0 Not tainted 3.10.0-rc6-01850-gba0682e #11 [ 163.690046] task: ef04c000 ti: ef03e000 task.ti: ef03e000 [ 163.695467] PC is at mvneta_probe+0x34c/0xabc [...] Signed-off-by: Ezequiel Garcia <ezequiel.garcia@free-electrons.com> Acked-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Signed-off-by: Jason Cooper <jason@lakedaemon.net>

2013-06-23perf: Drop sample rate when sampling is too slowDave Hansen
This patch keeps track of how long perf's NMI handler is taking, and also calculates how many samples perf can take a second. If the sample length times the expected max number of samples exceeds a configurable threshold, it drops the sample rate. This way, we don't have a runaway sampling process eating up the CPU. This patch can tend to drop the sample rate down to level where perf doesn't work very well. *BUT* the alternative is that my system hangs because it spends all of its time handling NMIs. I'll take a busted performance tool over an entire system that's busted and undebuggable any day. BTW, my suspicion is that there's still an underlying bug here. Using the HPET instead of the TSC is definitely a contributing factor, but I suspect there are some other things going on. But, I can't go dig down on a bug like that with my machine hanging all the time.

2013-06-23x86: Warn when NMI handlers take large amounts of timeDave Hansen
I have a system which is causing all kinds of problems. It has 8 NUMA nodes, and lots of cores that can fight over cachelines. If things are not working _perfectly_, then NMIs can take longer than expected. If we get too many of them backed up to each other, we can easily end up in a situation where we are doing nothing *but* running NMIs. The biggest problem, though, is that this happens _silently_. You might be lucky to get an hrtimer warning, but most of the time system simply hangs. This patch should at least give us some warning before we fall off the cliff. the warnings look like this: nmi_handle: perf_event_nmi_handler() took: 26095071 ns The message is triggered whenever we notice the longest NMI we've seen to date. You can always view and reset this value via the debugfs interface if you like.

2013-06-23PCI / ACPI: Use boot-time resource allocation rules during hotplugJiang Liu
On x86 platforms, the kernel respects PCI resource assignments from the BIOS and only reassigns resources for unassigned BARs at boot time. However, with the ACPI-based hotplug (acpiphp), it ignores the BIOS' PCI resource assignments completely and reassigns all resources by itself. This causes differences in PCI resource allocation between boot time and runtime hotplug to occur, which is generally undesirable and sometimes actively breaks things. Namely, if there are enough resources, reassigning all PCI resources during runtime hotplug should work, but it may fail if the resources are constrained. This may happen, for instance, when some PCI devices with huge MMIO BARs are involved in the runtime hotplug operations, because the current PCI MMIO alignment algorithm may waste huge chunks of MMIO address space in those cases. On the Alexander's Sony VAIO VPCZ23A4R the BIOS allocates limited MMIO resources for the dock station which contains a device (graphics adapter) with a 256MB MMIO BAR. An attempt to reassign that during runtime hotplug causes the dock station MMIO window to be exhausted and acpiphp fails to allocate resources for the majority of devices on the dock station as a result. To prevent that from happening, modify acpiphp to follow the boot time resources allocation behavior so that the BIOS' resource assignments are respected during runtime hotplug too.

2013-06-23ACPI / dock: Initialize ACPI dock subsystem upfrontJiang Liu
Commit 3b63aaa70e1 (PCI: acpiphp: Do not use ACPI PCI subdriver mechanism) introduced an ACPI dock support regression, because it changed the relative initialization order of the ACPI dock subsystem and the ACPI-based PCI hotplug (acpiphp). Namely, the ACPI dock subsystem has to be initialized before acpiphp_enumerate_slots() is first run, which after commit 3b63aaa70e1 happens during the initial enumeration of the PCI hierarchy triggered by the initial ACPI namespace scan in acpi_scan_init(). For this reason, the dock subsystem has to be initialized before the initial ACPI namespace scan in acpi_scan_init(). To make that happen, modify the ACPI dock subsystem to be non-modular and add the invocation of its initialization routine, acpi_dock_init(), to acpi_scan_init() directly before the initial namespace scan.

2013-06-22trace,x86: Do not call local_irq_save() in load_current_idt()Steven Rostedt (Red Hat)
As load_current_idt() is now what is used to update the IDT for the switches needed for NMI, lockdep debug, and for tracing, it must not call local_irq_save(). This is because one of the users of this is lockdep, which does tracing of local_irq_save() and when the debug trap is hit, we need to update the IDT before tracing interrupts being disabled. As load_current_idt() is used to do this, calling local_irq_save() which lockdep traces, defeats the point of calling load_current_idt(). As interrupts are already disabled when used by lockdep and NMI, the only other user is tracing that can disable interrupts itself. Simply have the tracing update disable interrupts before calling load_current_idt() instead of breaking the other users. Here's the dump that happened: ------------[ cut here ]------------ WARNING: at /work/autotest/nobackup/linux-test.git/kernel/fork.c:1196 copy_process+0x2c3/0x1398() DEBUG_LOCKS_WARN_ON(!p->hardirqs_enabled) Modules linked in: CPU: 1 PID: 4570 Comm: gdm-simple-gree Not tainted 3.10.0-rc3-test+ #5 Hardware name: /DG965MQ, BIOS MQ96510J.86A.0372.2006.0605.1717 06/05/2006 ffffffff81d2a7a5 ffff88006ed13d50 ffffffff8192822b ffff88006ed13d90 ffffffff81035f25 ffff8800721c6000 ffff88006ed13da0 0000000001200011 0000000000000000 ffff88006ed5e000 ffff8800721c6000 ffff88006ed13df0 Call Trace: [<ffffffff8192822b>] dump_stack+0x19/0x1b [<ffffffff81035f25>] warn_slowpath_common+0x67/0x80 [<ffffffff81035fe1>] warn_slowpath_fmt+0x46/0x48 [<ffffffff812bfc5d>] ? __raw_spin_lock_init+0x31/0x52 [<ffffffff810341f7>] copy_process+0x2c3/0x1398 [<ffffffff8103539d>] do_fork+0xa8/0x260 [<ffffffff810ca7b1>] ? trace_preempt_on+0x2a/0x2f [<ffffffff812afb3e>] ? trace_hardirqs_on_thunk+0x3a/0x3f [<ffffffff81937fe7>] ? sysret_check+0x1b/0x56 [<ffffffff81937fe7>] ? sysret_check+0x1b/0x56 [<ffffffff810355cf>] SyS_clone+0x16/0x18 [<ffffffff81938369>] stub_clone+0x69/0x90 [<ffffffff81937fc2>] ? system_call_fastpath+0x16/0x1b ---[ end trace 8b157a9d20ca1aa2 ]--- in fork.c: #ifdef CONFIG_PROVE_LOCKING DEBUG_LOCKS_WARN_ON(!p->hardirqs_enabled); <-- bug here DEBUG_LOCKS_WARN_ON(!p->softirqs_enabled); #endif Cc: Seiji Aguchi <seiji.aguchi@hds.com> Signed-off-by: Steven Rostedt <rostedt@goodmis.org>

2013-06-21ARM: Kirkwood: Fix the internal register ranges translationEzequiel Garcia
Although the internal register window size is 1 MiB, the previous ranges translation for the internal register space had a size of 0x4000000. This was done to allow the crypto and nand node to access the corresponding 'sram' and 'nand' decoding windows. In order to describe the hardware more accurately, we declare the real 1 MiB internal register space in the ranges, and add a translation entry for the nand node to access the 'nand' window. This commit will make future improvements on the MBus DT binding easier. Signed-off-by: Ezequiel Garcia <ezequiel.garcia@free-electrons.com> Signed-off-by: Jason Cooper <jason@lakedaemon.net>

With a periodic tick, the cpu never enters the state1 with both 10000 and 100000. With a tickless system, it enters to state1 much more often with the initial value, roughly x7 more.
