From d6e640f9766e2fb9aa3853b4ff19e4d7d5d7e373 Mon Sep 17 00:00:00 2001 From: Oliver Hartkopp Date: Tue, 8 May 2012 22:20:33 +0200 Subject: can: update documentation wording error frames -> error messages As Heinz-Juergen Oertel pointed out 'CAN error frames' are a already defined term for the CAN protocol violation indication on the wire. To avoid confusion with the error messages created by CAN drivers available via CAN RAW sockets update the documentation and change the naming from 'error frames' to 'error messages' or 'error message frames'.

The KVM_PPC_ALLOCATE_HTAB ioctl is a VM ioctl and takes as its parameter a pointer to a u32 containing the desired order of the HPT (log base 2 of the size in bytes), which is updated on successful return to the actual order of the HPT which was allocated. There must be no vcpus running at the time of this ioctl. To enforce this, we now keep a count of the number of vcpus running in kvm->arch.vcpus_running. If the ioctl is called when a HPT has already been allocated, we don't reallocate the HPT but just clear it out. We first clear the kvm->arch.rma_setup_done flag, which has two effects: (a) since we hold the kvm->lock mutex, it will prevent any vcpus from starting to run until we're done, and (b) it means that the first vcpu to run after we're done will re-establish the VRMA if necessary. If userspace doesn't call this ioctl before running the first vcpu, the kernel will allocate a default-sized HPT at that point. We do it then rather than when creating the VM, as the code did previously, so that userspace has a chance to do the ioctl if it wants. When allocating the HPT, we can allocate either from the kernel page allocator, or from the preallocated pool. If userspace is asking for a different size from the preallocated HPTs, we first try to allocate using the kernel page allocator. Then we try to allocate from the preallocated pool, and then if that fails, we try allocating decreasing sizes from the kernel page allocator, down to the minimum size allowed (256kB). Note that the kernel page allocator limits allocations to 1 << CONFIG_FORCE_MAX_ZONEORDER pages, which by default corresponds to 16MB (on 64-bit powerpc, at least).

Also, instead of searching for unlinked inodes in every resource group that's checked for free space, gfs2 can store the number of unlinked but inodes in the lvb, and only check for unlinked inodes if it will find some. The first time a resource group is locked, the lvb must initialized. Since this involves counting the unlinked inodes in the resource group, this takes a little extra time. But after that, if the resource group is locked with GL_SKIP, the buffer head won't be read in unless it's actually needed. Enabling the resource groups lvbs is done via the rgrplvb mount option. If this option isn't set, the lvbs will still be set and updated, but they won't be verfied or used by the filesystem. To safely turn on this option, all of the nodes mounting the filesystem must be running code with this patch, and the filesystem must have been completely unmounted since they were updated.

Occasionally hardware screws this up and uses the source ID of a different device (often the wrong function number of a multifunction device). A specific Ricoh multifunction device is a prime example of this problem and included in this patch. Given a pci_dev, this function returns the pci_dev to use as the source ID for DMA. When hardware works correctly, this returns the input device. For the components of the Ricoh multifunction device, it returns the pci_dev for function 0. This will be used by IOMMU drivers for determining the boundaries of IOMMU groups as multiple devices using the same source ID must be contained within the same group. This can also be used by existing streaming DMA paths for the same purpose.

The makeup of the capability varies substantially between v1 and v2: Version 1 of the PCI Express Capability (defined by PCI Express 1.0 and 1.1 base) neither requires the endpoint to implement the entire PCIe capability structure nor specifies default values of registers that are not implemented by the device. Version 2 of the PCI Express Capability (defined by PCIe 1.1 Capability Structure Expansion ECN, PCIe 2.0, 2.1, and 3.0) added additional registers to the structure and requires all registers to be either implemented or hardwired to 0. Due to the differences in the capability structures, code dealing with capability features must be careful not to access the additional registers introduced with v2 unless the device is specifically known to be a v2 capable device. Otherwise, attempts to access non-existant registers will occur. This is a subtle issue that is hard to track down when it occurs (and it has - see commit 864d296cf94). To try and help mitigate such occurrences, this patch introduces pci_pcie_cap2() which is similar to pci_pcie_cap() but also checks that the PCIe capability version is >= 2. pci_pcie_cap2() should be used for qualifying PCIe capability features introduced after v1.

Intermediate switches between an endpoint and the root bus can redirect DMA back downstream before things like IOMMUs have a chance to intervene. Legacy PCI is always susceptible to this as it operates on a shared bus. PCIe added a new capability to describe and control this behavior, Access Control Services, or ACS. The utility function pci_acs_enabled() allows us to test the ACS capabilities of an individual devices against a set of flags while pci_acs_path_enabled() tests a complete path from a given downstream device up to the specified upstream device. We also include the ability to add device specific tests as it's likely we'll see devices that do not implement ACS, but want to indicate support for various capabilities in this space.

d0daebc3d622f95db181601cb0c4a0781f74f758 Mon Sep 17 00:00:00 2001 From: Thomas Graf Date: Tue, 12 Jun 2012 00:44:01 +0000 Subject: ipv4: Add interface option to enable routing of 127.0.0.0/8 Routing of 127/8 is tradtionally forbidden, we consider packets from that address block martian when routing and do not process corresponding ARP requests. This is a sane default but renders a huge address space practically unuseable. The RFC states that no address within the 127/8 block should ever appear on any network anywhere but it does not forbid the use of such addresses outside of the loopback device in particular. For example to address a pool of virtual guests behind a load balancer. This patch adds a new interface option 'route_localnet' enabling routing of the 127/8 address block and processing of ARP requests on a specific interface. Note that for the feature to work, the default local route covering 127/8 dev lo needs to be removed. Example: $ sysctl -w net.ipv4.conf.eth0.route_localnet=1 $ ip route del 127.0.0.0/8 dev lo table local $ ip addr add 127.1.0.1/16 dev eth0 $ ip route flush cache V2: Fix invalid check to auto flush cache (thanks davem) Signed-off-by: Thomas Graf Acked-by: Neil Horman Signed-off-by: David S.

Moreover, we can monitor the helper process and restart it in case of problems. * Security: Avoid complex string matching and mangling in kernel-space running in privileged mode. Going further, we can even think about running user-space helpers as a non-root process. * Extensibility: It allows the development of very specific helpers (most likely non-standard proprietary protocols) that are very likely not to be accepted for mainline inclusion in the form of kernel-space connection tracking helpers. This patch adds the infrastructure to allow the implementation of user-space conntrack helpers by means of the new nfnetlink subsystem `nfnetlink_cthelper' and the existing queueing infrastructure (nfnetlink_queue). I had to add the new hook NF_IP6_PRI_CONNTRACK_HELPER to register ipv[4|6]_helper which results from splitting ipv[4|6]_confirm into two pieces. This change is required not to break NAT sequence adjustment and conntrack confirmation for traffic that is enqueued to our user-space conntrack helpers. Basic operation, in a few steps: 1) Register user-space helper by means of `nfct': nfct helper add ftp inet tcp [ It must be a valid existing helper supported by conntrack-tools ] 2) Add rules to enable the FTP user-space helper which is used to track traffic going to TCP port 21. For locally generated packets: iptables -I OUTPUT -t raw -p tcp --dport 21 -j CT --helper ftp For non-locally generated packets: iptables -I PREROUTING -t raw -p tcp --dport 21 -j CT --helper ftp 3) Run the test conntrackd in helper mode (see example files under doc/helper/conntrackd.conf conntrackd 4) Generate FTP traffic going, if everything is OK, then conntrackd should create expectations (you can check that with `conntrack': conntrack -E expect [NEW] 301 proto=6 src=192.168.1.136 dst=130.89.148.12 sport=0 dport=54037 mask-src=255.255.255.255 mask-dst=255.255.255.255 sport=0 dport=65535 master-src=192.168.1.136 master-dst=130.89.148.12 sport=57127 dport=21 class=0 helper=ftp [DESTROY] 301 proto=6 src=192.168.1.136 dst=130.89.148.12 sport=0 dport=54037 mask-src=255.255.255.255 mask-dst=255.255.255.255 sport=0 dport=65535 master-src=192.168.1.136 master-dst=130.89.148.12 sport=57127 dport=21 class=0 helper=ftp This confirms that our test helper is receiving packets including the conntrack information, and adding expectations in kernel-space. The user-space helper can also store its private tracking information in the conntrack structure in the kernel via the CTA_HELP_INFO.

It will provide two ways of setting the ramp_delay for a regulator: First, by setting it as constraints in board file(for configurable regulators) and set_machine_constraints() will take care of setting it on hardware by calling(the provided) .set_ramp_delay() operation(callback). Second, by setting it as data in regulator_desc(as fixed/default ramp_delay rate) for a regulator in driver. regulator_set_voltage_time_sel() will give preference to constraints->ramp_delay while reading ramp_delay rate for regulator. Similarly users should also take care accordingly while refering ramp_delay rate(in case of implementing their private .set_voltage_time_sel() callbacks for different regulators).

Configuration should provide minimum and maximum register for virtual range, details of selector field for page selection, minimum and maximum register of data window for indirect access.

This adds a static buffer for 32 messages to each uhid device. Each message is dynamically allocated so the uhid_device structure does not get too big. uhid_queue() adds a message to the buffer. If the buffer is full, the message is discarded. uhid_queue_event() is an helper for messages without payload. This also adds a public header: uhid.h. It contains the declarations for the user-space API. It is built around "struct uhid_event" which contains a type field which specifies the event type and each event can then add a variable-length payload. For now, there is only a dummy event but later patches will add new event types and payloads.

We now forward these requests directly to user-space so the transport-level driver can correctly send it to the device or handle it correspondingly. There is no way to signal back whether the transmission was successful, moreover, there might be lots of messages coming out from the driver flushing the output-queue. However, there is currently no driver that causes this so we are safe. If some drivers need to transmit lots of data this way, we need a method to synchronize this and can implement another UHID_OUTPUT_SYNC event.

If it doesn't do this in a timely manner, the request is discarded silently. We serialize the feature requests, that is, there is always only a single active feature-request sent to user-space, other requests have to wait. HIDP and USB-HID do it the same way. Because we discard feature-requests silently, we must make sure to match a response to the corresponding request. We use sequence-IDs for this so user-space must copy the ID from the request into the answer. Feature-answers are ignored if they do not contain the same ID as the currently pending feature request. Internally, we must make sure that feature-requests are synchronized with UHID_DESTROY and close() events. We must not dead-lock when closing the HID device, either, so we have to use separate locks.

This is sufficient in principle, since there is no reason to register multiple such regulators. The user can simply supply all consumers in one array and use it to initialise such a regulator. However, in some cases it can be convenient to register multiple such regulators. This is also a prerequisite for the upcoming patch, that will add a voltage parameter to this function. The original function is provided as a wrapper macro.

This implements a bit of rework for the PFC code, making the core itself slightly more pluggable and moving out the gpio chip handling completely. The API is preserved in such a way that platforms that depend on it for early configuration are still able to do so, while making it possible to migrate to alternate interfaces going forward. This is the first step of chainsawing necessary to support the pinctrl API, with the eventual goal being able to decouple pin function state from the gpio API while retaining gpio chip tie-in for gpio pin functions only, relying on the pinctrl/pinmux API for non-gpio function demux.

The main motivation behind this patch is to provide an option to disable the feature as it adds an additional cost to routing that reduces overall throughput by up to 5%. For example one of my systems went from 12.1Mpps to 11.6 after the early socket demux was added. It looks like the reason for the regression is that we are now having to perform two lookups, first the one for an established socket, and then the one for the routing table.

This patch only enables runtime D3cold support; it does not enable D3cold support during system suspend/hibernate. D3cold is the deepest power saving state for a PCIe device, where its main power is removed. While it is in D3cold, you can't access the device at all, not even its configuration space (which is still accessible in D3hot). Therefore the PCI PM registers can not be used to transition into/out of the D3cold state; that must be done by platform logic such as ACPI _PR3. To support wakeup from D3cold, a system may provide auxiliary power, which allows a device to request wakeup using a Beacon or the sideband WAKE# signal. WAKE# is usually connected to platform logic such as ACPI GPE. This is quite different from other power saving states, where devices request wakeup via a PME message on the PCIe link. Some devices, such as those in plug-in slots, have no direct platform logic. For example, there is usually no ACPI _PR3 for them. D3cold support for these devices can be done via the PCIe Downstream Port leading to the device. When the PCIe port is powered on/off, the device is powered on/off too. Wakeup events from the device will be notified to the corresponding PCIe port.

This patch intends to grow the IOMMU group concept into something a bit more consumable. To do this, we first create an object representing the group, struct iommu_group. This structure is allocated (iommu_group_alloc) and filled (iommu_group_add_device) by the iommu driver. The iommu driver is free to add devices to the group using it's own set of policies. This allows inclusion of devices based on physical hardware or topology limitations of the platform, as well as soft requirements, such as multi-function trust levels or peer-to-peer protection of the interconnects. Each device may only belong to a single iommu group, which is linked from struct device.iommu_group. IOMMU groups are maintained using kobject reference counting, allowing for automatic removal of empty, unreferenced groups. It is the responsibility of the iommu driver to remove devices from the group (iommu_group_remove_device). IOMMU groups also include a userspace representation in sysfs under /sys/kernel/iommu_groups. When allocated, each group is given a dynamically assign ID (int). The ID is managed by the core IOMMU group code to support multiple heterogeneous iommu drivers, which could potentially collide in group naming/numbering. This also keeps group IDs to small, easily managed values. A directory is created under /sys/kernel/iommu_groups for each group. A further subdirectory named "devices" contains links to each device within the group. The iommu_group file in the device's sysfs directory, which formerly contained a group number when read, is now a link to the iommu group. Example: $ ls -l /sys/kernel/iommu_groups/26/devices/ total 0 lrwxrwxrwx. 1 root root 0 Apr 17 12:57 0000:00:1e.0 -> ../../../../devices/pci0000:00/0000:00:1e.0 lrwxrwxrwx. 1 root root 0 Apr 17 12:57 0000:06:0d.0 -> ../../../../devices/pci0000:00/0000:00:1e.0/0000:06:0d.0 lrwxrwxrwx. 1 root root 0 Apr 17 12:57 0000:06:0d.1 -> ../../../../devices/pci0000:00/0000:00:1e.0/0000:06:0d.1 $ ls -l /sys/kernel/iommu_groups/26/devices/*/iommu_group [truncating perms/owner/timestamp] /sys/kernel/iommu_groups/26/devices/0000:00:1e.0/iommu_group -> ../../../kernel/iommu_groups/26 /sys/kernel/iommu_groups/26/devices/0000:06:0d.0/iommu_group -> ../../../../kernel/iommu_groups/26 /sys/kernel/iommu_groups/26/devices/0000:06:0d.1/iommu_group -> ../../../../kernel/iommu_groups/26 Groups also include several exported functions for use by user level driver providers, for example VFIO. These include: iommu_group_get(): Acquires a reference to a group from a device iommu_group_put(): Releases reference iommu_group_for_each_dev(): Iterates over group devices using callback iommu_group_[un]register_notifier(): Allows notification of device add and remove operations relevant to the group iommu_group_id(): Return the group number This patch also extends the IOMMU API to allow attaching groups to domains. This is currently a simple wrapper for iterating through devices within a group, but it's expected that the IOMMU API may eventually make groups a more integral part of domains. Groups intentionally do not try to manage group ownership. A user level driver provider must independently acquire ownership for each device within a group before making use of the group as a whole. This may change in the future if group usage becomes more pervasive across both DMA and IOMMU ops. Groups intentionally do not provide a mechanism for driver locking or otherwise manipulating driver matching/probing of devices within the group. Such interfaces are generic to devices and beyond the scope of IOMMU groups. If implemented, user level providers have ready access via iommu_group_for_each_dev and group notifiers. iommu_device_group() is removed here as it has no users. The replacement is: group = iommu_group_get(dev); id = iommu_group_id(group); iommu_group_put(group); AMD-Vi & Intel VT-d support re-added in following patches.

Already existing is the ability of MDIO bus drivers to use clause 45, with the MII_ADDR_C45 flag. Here we add struct phy_c45_device_ids to hold the device identifier registers present in clause 45. struct phy_device gets a couple of new fields: c45_ids to hold the identifiers and is_c45 to signal that it is clause 45. get_phy_device() gets a new parameter is_c45 to indicate that the PHY device should use the clause 45 protocol, and its callers are adjusted to pass false. The follow-on patch to of_mdio.c will pass true where appropriate. EXPORT phy_device_create() so that the follow-on patch to of_mdio.c can use it to create phy devices for PHYs, that have non-standard device identifier registers, based on the device tree bindings.

Allow PHY drivers to supply their own device matching function (match_phy_device()), or to be matched OF compatible properties. PHYs following IEEE802.3 clause 45 have more than one device identifier constants, which breaks the default device matching code. Other 10G PHYs don't follow the standard manufacturer/device identifier register layout standards, but they do use the standard MDIO bus protocols for register access. Both of these require adjustments to the PHY driver to device matching code. If the there is an of_node associated with such a PHY, we can match it to its driver using the "compatible" properties, just as we do with certain platform devices. If the "compatible" property match fails, first check if there is a driver supplied matching function, and if not fall back to the existing identifier matching rules.

This did not cause any failures to the system itself (no crashes), but caused unnecessary failures for reading the trace files. Added a helper function called 'trace_buffer_iter()' that returns the buffer_iter item or NULL if it is not defined or the array was not allocated.

I've populated this structure by looking for NULL and zero parameters at the existing code. The remaining parameters that always need to be set are still left in the original interface. That includes optional parameters for the netlink socket creation. This allows easy extensibility of this interface in the future. This patch also adapts all callers to use this new interface.

This patch adds the support for the Energy-Efficient Ethernet (EEE) to the Physical Abstraction Layer. To support the EEE we have to access to the MMD registers 3.20 and 7.60/61. So two new functions have been added to read/write the MMD registers (clause 45). An Ethernet driver (I tested the stmmac) can invoke the phy_init_eee to properly check if the EEE is supported by the PHYs and it can also set the clock stop enable bit in the 3.0 register. The phy_get_eee_err can be used for reporting the number of time where the PHY failed to complete its normal wake sequence. In the end, this patch also adds the EEE ethtool support implementing: o phy_ethtool_set_eee o phy_ethtool_get_eee v1: initial patch v2: fixed some errors especially on naming convention v3: renamed again the mmd read/write functions thank to Ben's feedback v4: moved file to phy.c and added the ethtool support. v5: fixed phy_adv_to_eee, phy_eee_to_supported, phy_eee_to_adv return values according to ethtool API (thanks to Ben's feedback). Renamed some macros to avoid too long names. v6: fixed kernel-doc comments to be properly parsed. Fixed the phy_init_eee function: we need to check which link mode was autonegotiated and then the corresponding bits in 7.60 and 7.61 registers. v7: reviewed the way to get the negotiated settings. v8: fixed a problem in the phy_init_eee return value erroneously added when included the phy_read_status call. v9: do not remove the MDIO_AN_EEE_ADV_100TX and MDIO_AN_EEE_ADV_1000T and fixed the eee_{cap,lp,adv} declaration as "int" instead of u16.

Wysocki" Date: Tue, 3 Jul 2012 19:07:42 +0200 Subject: PM / Domains: Add preliminary support for cpuidle, v2 On some systems there are CPU cores located in the same power domains as I/O devices. Then, power can only be removed from the domain if all I/O devices in it are not in use and the CPU core is idle. Add preliminary support for that to the generic PM domains framework. First, the platform is expected to provide a cpuidle driver with one extra state designated for use with the generic PM domains code. This state should be initially disabled and its exit_latency value should be set to whatever time is needed to bring up the CPU core itself after restoring power to it, not including the domain's power on latency. Its .enter() callback should point to a procedure that will remove power from the domain containing the CPU core at the end of the CPU power transition. The remaining characteristics of the extra cpuidle state, referred to as the "domain" cpuidle state below, (e.g. power usage, target residency) should be populated in accordance with the properties of the hardware. Next, the platform should execute genpd_attach_cpuidle() on the PM domain containing the CPU core. That will cause the generic PM domains framework to treat that domain in a special way such that: * When all devices in the domain have been suspended and it is about to be turned off, the states of the devices will be saved, but power will not be removed from the domain. Instead, the "domain" cpuidle state will be enabled so that power can be removed from the domain when the CPU core is idle and the state has been chosen as the target by the cpuidle governor. * When the first I/O device in the domain is resumed and __pm_genpd_poweron(() is called for the first time after power has been removed from the domain, the "domain" cpuidle state will be disabled to avoid subsequent surprise power removals via cpuidle. The effective exit_latency value of the "domain" cpuidle state depends on the time needed to bring up the CPU core itself after restoring power to it as well as on the power on latency of the domain containing the CPU core. Thus the "domain" cpuidle state's exit_latency has to be recomputed every time the domain's power on latency is updated, which may happen every time power is restored to the domain, if the measured power on latency is greater than the latency stored in the corresponding generic_pm_domain structure.

Since there are a bunch of fiddly things to get right like handling the operations when the enable signal is tied to a rail and it's just replicated code add support for this to the core. Drivers should set ena_gpio in their config if they have a GPIO control, using ena_gpio_flags to specify any flags (including GPIOF_OUT_INIT_ for the initial state) and ena_gpio_invert if the GPIO is active low. The core will then override any enable and disable operations the driver has and instead control the specified GPIO. This will in the future also allow us to further extend the core by identifying when several enable signals have been tied together and handling this properly.

When the steering mode is device managed, the code is modified such that L2 based rules set by the mlx4_en driver for Ethernet unicast and multicast, and the IB stack multicast attach calls done through the mlx4_ib driver are all routed to use the device managed API. When attaching rule using device managed flow steering API, the firmware returns a 64 bit registration id, which is to be provided during detach.

Future work should be done to allow configuring the flow-steering hash function with common, non proprietary means. Signed-off-by: Hadar Hen Zion Signed-off-by: Or Gerlitz Signed-off-by: David S.

For details, see the IOBL_ADR register and the EN1K bit in the CNF register in the Intel 82870P2 (P64H2). These quirks complicate the code that reads P2P bridge windows (pci_read_bridge_io() and pci_cfg_fake_ranges()) because the bridge I/O resource is updated in the HEADER quirk, in pci_read_bridge_io(), in pci_setup_bridge(), and again in the FINAL quirk. This is confusing and makes it impossible to reassign the bridge windows after FINAL quirks are run. This patch adds support for 1K windows in the generic paths, so the HEADER quirk only has to enable this support. The FINAL quirk, which used to undo damage done by pci_setup_bridge(), is no longer needed. This removes "if (!res->start) res->start = ..." from pci_read_bridge_io(); that was part of 9d265124d051 to avoid overwriting the resource filled in by the quirk. Since pci_read_bridge_io() itself now knows about granularity, the quirk no longer updates the resource and this test is no longer needed.

This begins the migration of the PFC core to the pinctrl subsystem. Initial support is very basic, with the bulk of the implementation simply being nopped out in such a way to allow registration with the pinctrl core to succeed. The gpio chip driver is stripped down considerably now relying purely on pinctrl API calls to manage the bulk of its operations. This provides a basis for further PFC refactoring, including decoupling pin functions from the GPIO API, establishing pin groups, and so forth. These will all be dealt with incrementally so as to introduce as few growing and migratory pains to tree-wide PFC pinmux users today. When the interfaces have been well established and in-tree users have been migrated off of the legacy interfaces it will be possible to strip down the core considerably, leading to eventual drivers/pinctrl rehoming.

If the capability bit for this event is set in dev-caps, the event is used (by the driver setting the PORT_MNG_CHG_EVENT bit in the async event mask in the MAP_EQ fw command). In this case, when the driver passes incoming SMP PORT_INFO SET mads to the FW, the FW generates port management change events to signal any changes to the driver. If the FW generates these events, smp_snoop shouldn't be invoked in ib_process_mad(), or duplicate events will occur (once from the FW-generated event, and once from smp_snoop). In the case where the FW does not generate port management change events smp_snoop needs to be invoked to create these events. The flow in smp_snoop has been modified to make use of the same procedures as in the fw-generated-event event case to generate the port management events (LID change, Client-rereg, Pkey change, and/or GID change). Port management change event handling required changing the mlx4_ib_event and mlx4_dispatch_event prototypes; the "param" argument (last argument) had to be changed to unsigned long in order to accomodate passing the EQE pointer. We also needed to move the definition of struct mlx4_eqe from net/mlx4.h to file device.h -- to make it available to the IB driver, to handle port management change events.

This was fixed in apci idle driver [2].But intel_idle driver does not have this fix. Thus instead of replicating the fix in both the idle drivers, or in more platform specific idle drivers if needed, the more general cpuidle infrastructure could handle this. A suspend callback in cpuidle_driver could handle this fix. But a cpuidle_driver provides only basic functionalities like platform idle state detection capability and mechanisms to support entry and exit into CPU idle states. All other cpuidle functions are found in the cpuidle generic infrastructure for good reason that all cpuidle drivers, irrepective of their platforms will support these functions. One option therefore would be to register a suspend callback in cpuidle which handles this fix. This could be called through a PM_SUSPEND_PREPARE notifier. But this is too generic a notfier for a driver to handle. Also, ideally the job of cpuidle is not to handle side effects of suspend. It should expose the interfaces which "handle cpuidle 'during' suspend" or any other operation, which the subsystems call during that respective operation. The fix demands that during suspend, no cpus should be allowed to enter deep C-states. The interface cpuidle_uninstall_idle_handler() in cpuidle ensures that. Not just that it also kicks all the cpus which are already in idle out of their idle states which was being done during cpu hotplug through a CPU_DYING_FROZEN callbacks. Now the question arises about when during suspend should cpuidle_uninstall_idle_handler() be called. Since we are dealing with drivers it seems best to call this function during dpm_suspend(). Delaying the call till dpm_suspend_noirq() does no harm, as long as it is before cpu_hotplug_begin() to avoid race conditions with cpu hotpulg operations. In dpm_suspend_noirq(), it would be wise to place this call before suspend_device_irqs() to avoid ugly interactions with the same. Ananlogously, during resume.

These proxy QPs send their packets to a "tunnel" QP owned by the master. The master then forwards the MAD (after any required paravirtualization) to the real special QP, which sends out the MAD. For security reasons (i.e., to prevent guests from sending MADs to tunnel QPs belonging to other guests), each proxy-tunnel QP pair is assigned a unique, reserved, Q_Key. These Q_Keys are available only for proxy and tunnel QPs -- if the guest tries to use these Q_Keys with other QPs, it will fail. This patch introduces a mechanism for reserving a block of 64K Q_Keys for proxy/tunneling use. The patch introduces also two new fields into mlx4_dev: base_sqpn and base_tunnel_sqpn. In SR-IOV mode, the QP numbers for the "real," proxy, and tunnel sqps are added to the reserved QPN area (so that they will not change). There are 8 special QPs per port in the HCA, and each of them is assigned both a proxy and a tunnel QP, for each VF and for the PF as well in SR-IOV mode. The QPNs for these QPs are arranged as follows: 1. The real SQP numbers (8) 2. The proxy SQPs (8 * (max number of VFs + max number of PFs) 3. The tunnel SQPs (8 * (max number of VFs + max number of PFs) To support these QPs, two new fields are added to struct mlx4_dev: base_sqp: this is the QP number of the first of the real SQPs base_tunnel_sqp: this is the qp number of the first qp in the tunnel sqp region. (On guests, this is the first tunnel sqp of the 8 which are assigned to that guest). In addition, in SR-IOV mode, sqp_start is the number of the first proxy SQP in the proxy SQP region. (In guests, this is the first proxy SQP of the 8 which are assigned to that guest) Note that in non-SR-IOV mode, there are no proxies and no tunnels. In this case, sqp_start is set to sqp_base -- which minimizes code changes.

In addition, in SR-IOV mode, do the following: 1. Reduce reported P_Key table size by 1. This is done to reserve the highest P_Key index for internal use, for declaring an invalid P_Key in P_Key paravirtualization. We require a P_Key index which always contain an invalid P_Key value for this purpose (i.e., one which cannot be modified by the subnet manager). The way to do this is to reduce the P_Key table size reported to the subnet manager by 1, so that it will not attempt to access the P_Key at index #127. 2. Paravirtualize the GID table size to 1. Thus, each guest sees only a single GID (at its paravirtualized index 0). In addition, since we are paravirtualizing the GID table size to 1, we add paravirtualization of the master GID event here (i.e., we do not do ib_dispatch_event() for the GUID change event on the master, since its (only) GUID never changes).

For instance, say a value of 1 could signify divide by 6 and a value of 2 could signify divide by 4 etc. Also there are dividers where not all values possible based on the bitfield width are valid. For instance a 3 bit wide bitfield can be used to program a value from 0 to 7. However its possible that only 0 to 4 are valid values. All these cases need the platform code to pass a simple table of divider/value tuple, so the framework knows the exact value to be written based on the divider calculation and can also do better error checking. This patch adds support for such rate table based dividers and as part of the support adds a new registration function 'clk_register_divider_table()' and a new macro for static definition 'DEFINE_CLK_DIVIDER_TABLE'.

Platforms scan for clocks in DT with of_clk_init and a match table, and the register a provider through of_clk_add_provider. The provider's clk_src_get function will be called when a device references the provider's OF node for a clock reference. v6 (Rob Herring): - Return error values instead of NULL to match clock framework expectations v5 (Rob Herring): - Move from drivers/of into common clock subsystem - Squashed "dt/clock: add a simple provider get function" and "dt/clock: add function to get parent clock name" - Rebase to 3.4-rc1 - Drop CONFIG_OF_CLOCK and just use CONFIG_OF - Add missing EXPORT_SYMBOL to various functions - s/clock-output-name/clock-output-names/ - Define that fixed-clock binding is a single output v4 (Rob Herring): - Rework for common clk subsystem - Add of_clk_get_parent_name function v3: - Clarified documentation v2: - fixed errant ';' causing compile error - Editorial fixes from Shawn Guo - merged in adding lookup to clkdev - changed property names to match established convention. After working with the binding a bit it really made more sense to follow the lead of 'reg', 'gpios' and 'interrupts' by making the input simply 'clocks' & 'clock-names' instead of 'clock-input-*', and to only use clock-output* for the producer nodes. (Sorry Shawn, this will mean you need to change some code, but it should be trivial) - Add ability to inherit clocks from parent nodes by using an empty 'clock-ranges' property. Useful for busses. I could use some feedback on the new property name, 'clock-ranges' doesn't feel right to me.

TSO packets are sized/capped to half the limit, so that we have two TSO packets in flight, allowing better bandwidth use. As a side effect, setting the limit to 40000 automatically reduces the standard gso max limit (65536) to 40000/2 : It can help to reduce latencies of high prio packets, having smaller TSO packets. This means we divert sock_wfree() to a tcp_wfree() handler, to queue/send following frames when skb_orphan() [2] is called for the already queued skbs. Results on my dev machines (tg3/ixgbe nics) are really impressive, using standard pfifo_fast, and with or without TSO/GSO. Without reduction of nominal bandwidth, we have reduction of buffering per bulk sender : < 1ms on Gbit (instead of 50ms with TSO) < 8ms on 100Mbit (instead of 132 ms) I no longer have 4 MBytes backlogged in qdisc by a single netperf session, and both side socket autotuning no longer use 4 Mbytes. As skb destructor cannot restart xmit itself ( as qdisc lock might be taken at this point ), we delegate the work to a tasklet. We use one tasklest per cpu for performance reasons. If tasklet finds a socket owned by the user, it sets TSQ_OWNED flag. This flag is tested in a new protocol method called from release_sock(), to eventually send new segments. [1] New /proc/sys/net/ipv4/tcp_limit_output_bytes tunable [2] skb_orphan() is usually called at TX completion time, but some drivers call it in their start_xmit() handler. These drivers should at least use BQL, or else a single TCP session can still fill the whole NIC TX ring, since TSQ will have no effect.

Requests to interact with the internal tipc log buffer over netlink (in config.c) will report 'obsolete command'. This represents the final removal of any references to a struct print_buf, and the removal of the struct itself. We also get rid of a TIPC specific Kconfig in the process. Finally, log.h is removed since it is not needed anymore.

Using this the filesystem can look up, possibly create and open the file in one atomic operation. If it cannot perform this (e.g. the file type turned out to be wrong) it may signal this by returning NULL instead of an open struct file pointer. i_op->atomic_open() is only called if the last component is negative or needs lookup. Handling cached positive dentries here doesn't add much value: these can be opened using f_op->open(). If the cached file turns out to be invalid, the open can be retried, this time using ->atomic_open() with a fresh dentry. For now leave the old way of using open intents in lookup and revalidate in place. This will be removed once all the users are converted. David Howells noticed that if ->atomic_open() opens the file but does not create it, handle_truncate() will be called on it even if it is not a regular file. Fix this by checking the file type in this case too.

We should make the name of the capability more general to encourage reuse in related cases. (Whether or not this capability should also be used to govern the use of /sys/power/wake_lock is a question that needs to be separately resolved.) This patch renames the capability to CAP_BLOCK_SUSPEND. In order to ensure that the old capability name doesn't make it out into the wild, could you please apply and push up the tree to ensure that it is incorporated for the 3.5 release.

This is to ensure that workqueue is up and running while bringing up a CPU before other notifiers try to use workqueue on the CPU. Per-cpu workqueues are supposed to remain working and bound to the CPU for normal CPU_DOWN_PREPARE notifiers. This holds mostly true even with workqueue offlining running with higher priority because workqueue CPU_DOWN_PREPARE only creates a bound trustee thread which runs the per-cpu workqueue without concurrency management without explicitly detaching the existing workers. However, if the trustee needs to create new workers, it creates unbound workers which may wander off to other CPUs while CPU_DOWN_PREPARE notifiers are in progress. Furthermore, if the CPU down is cancelled, the per-CPU workqueue may end up with workers which aren't bound to the CPU. While reliably reproducible with a convoluted artificial test-case involving scheduling and flushing CPU burning work items from CPU down notifiers, this isn't very likely to happen in the wild, and, even when it happens, the effects are likely to be hidden by the following successful CPU down. Fix it by using different priorities for up and down notifiers - high priority for up operations and low priority for down operations. Workqueue cpu hotplug operations will soon go through further cleanup. Signed-off-by: Tejun Heo Cc: stable@vger.kernel.org Acked-by: "Rafael J.

An artifact if that was data structures to store/process an incoming ceph_msg_connect request and send an outgoing ceph_msg_connect_reply. Sadly, the negotiation code was referencing those structures and ignoring important information (like the peer's connect_seq) from the correct ones. Among other things, this fixes tight reconnect loops where the server sends RETRY_SESSION and we (the client) retries with the same connect_seq as last time. This bug pretty easily triggered by injecting socket failures on the MDS and running some fs workload like workunits/direct_io/test_sync_io.

However, as a result, the partition detection was no longer synchronized by async_synchronize_full() (which, despite the name, only synchronizes the global async space, not all of them). Which in turn meant that "wait_for_device_probe()" would not wait for the SCSI partitions to be parsed. And "wait_for_device_probe()" was what the boot time init code relied on for mounting the root filesystem. Now, most people never noticed this, because not only is it timing-dependent, but modern distributions all use initrd. So the root filesystem isn't actually on a disk at all. And then before they actually mount the final disk filesystem, they will have loaded the scsi-wait-scan module, which not only does the expected wait_for_device_probe(), but also does scsi_complete_async_scans(). [ Side note: scsi_complete_async_scans() had also been partially broken, but that was fixed in commit 43a8d39d0137 ("fix async probe regression"), so that same commit a7a20d103994 had actually broken setups even if you used scsi-wait-scan explicitly ] Solve this problem by just moving the scsi_complete_async_scans() call into wait_for_device_probe(). Everybody who wants to wait for device probing to finish really wants the SCSI probing to complete, so there's no reason not to do this. So now "wait_for_device_probe()" really does what the name implies, and properly waits for device probing to finish. This also removes the now unnecessary extra calls to scsi_complete_async_scans().

The data is from tcp_sendmsg() with flag MSG_FASTOPEN (implemented in a later patch). The length of the cookie in tcp_fastopen_req, init'd to 0, controls the type of the SYN. If the cookie is not cached (len==0), the host sends data-less SYN with Fast Open cookie request option to solicit a cookie from the remote. If cookie is not available (len > 0), the host sends a SYN-data with Fast Open cookie option. If cookie length is negative, the SYN will not include any Fast Open option (for fall back operations). To deal with middleboxes that may drop SYN with data or experimental TCP option, the SYN-data is only sent once. SYN retransmits do not include data or Fast Open options. The connection will fall back to regular TCP handshake. Signed-off-by: Yuchung Cheng Acked-by: Eric Dumazet Signed-off-by: David S.

The application should replace connect() with it to send data in the opening SYN packet. For blocking socket, sendmsg() blocks until all the data are buffered locally and the handshake is completed like connect() call. It returns similar errno like connect() if the TCP handshake fails. For non-blocking socket, it returns the number of bytes queued (and transmitted in the SYN-data packet) if cookie is available. If cookie is not available, it transmits a data-less SYN packet with Fast Open cookie request option and returns -EINPROGRESS like connect(). Using MSG_FASTOPEN on connecting or connected socket will result in simlar errno like repeating connect() calls. Therefore the application should only use this flag on new sockets.

The return check on of_clk_get_by_name takes (clk != NULL) as a successful DT lookup. But it's not the case. For any system that does not define clk lookup in device tree, ERR_PTR(-ENOENT) will be returned, and consequently, all the client drivers calling clk_get in their probe functions will fail to probe with error code -ENOENT returned. Fix the issue by checking of_clk_get_by_name return with !IS_ERR(clk), and update of_clk_get and of_clk_get_by_name for !CONFIG_OF build correspondingly.

Each domain, including the default one, registers itself on a global domain list when work is scheduled. Once all entries complete it exits that list. Waiting for the list to be empty syncs all in-flight work across all domains. Domains can opt-out of global syncing if they are declared as exclusive ASYNC_DOMAIN_EXCLUSIVE(). All stack-based domains have been declared exclusive since the domain may go out of scope as soon as the last work item completes. Statically declared domains are mostly ok, but async_unregister_domain() is there to close any theoretical races with pending async_synchronize_full waiters at module removal time.

When a timer fires but finds the socket is owned by the user, it rearms itself for an additional delay hoping next run will be more successful. tcp_write_timer() for example uses a 50ms delay for next try, and it defeats many attempts to get predictable TCP behavior in term of latencies. Use the recently introduced tcp_release_cb(), so that the user owning the socket will call various handlers right before socket release. This will permit us to post a followup patch to address the tcp_tso_should_defer() syndrome (some deferred packets have to wait RTO timer to be transmitted, while cwnd should allow us to send them sooner) Signed-off-by: Eric Dumazet Cc: Tom Herbert Cc: Yuchung Cheng Cc: Neal Cardwell Cc: Nandita Dukkipati Cc: H.K.

It has basic queue, flush_work, flush_worker operations which mostly match the workqueue counterparts; however, due to the way flush_work() is implemented, it has a noticeable difference of not allowing work items to be freed while being executed. While the current users of kthread_worker are okay with the current behavior, the restriction does impede some valid use cases. Also, removing this difference isn't difficult and actually makes the code easier to understand. This patch reimplements flush_kthread_work() such that it uses a flush_work item instead of queue/done sequence numbers.

This allows sockets that may be used by a kernel worker thread to be managed. For example in the iscsi case today a user can put iscsid in a netprio cgroup and control traffic will be sent with the correct sk_cgrp_prioidx value set but as soon as data is sent the kernel worker thread isssues a send and sk_cgrp_prioidx is updated with the kernel worker threads value which is the default case. It seems more correct to only update the field when the user explicitly sets it via control group infrastructure. This allows the users to manage sockets that may be used with other threads.

We are guaranteed that __fput() will be done before we return to userland (or exit). Note that for fput() from a kernel thread we get an async behaviour; it's almost always OK, but sometimes you might need to have __fput() completed before you do anything else. There are two mechanisms for that - a general barrier (flush_delayed_fput()) and explicit __fput_sync(). Both should be used with care (as was the case for fput() from kernel threads all along). See comments in fs/file_table.c for details.

Recent changes in ext4 have cut & pasted generic_file_llseek() back into fs/ext4/dir.c, but replicating this core code seems like a bad idea, especially since the copy has already diverged from the vfs. This patch updates generic_file_llseek_size to accept both a custom maximum offset, and a custom EOF position. With this in place, ext4_dir_llseek can pass in the appropriate maximum hash position for both maxsize and eof, and get what it wants. As far as I know, this does not fix any bugs - nfs in the kernel doesn't use SEEK_END, and I don't know of any user who does. But some ext4 folks seem keen on doing the right thing here, and I can't really argue.

Rename this setting from 'split_io' to the less-ambiguous 'max_io_len'. Change it from sector_t to uint32_t, which is plenty big enough, and introduce a wrapper function dm_set_target_max_io_len() to set it. Use sector_div() to process it now that it is not necessarily a power of 2.
