* ipv6: sysctl to restrict candidate source addressesErik Kline2015-07-22
| | | | | | | | | | | | | Per RFC 6724, section 4, "Candidate Source Addresses": It is RECOMMENDED that the candidate source addresses be the set of unicast addresses assigned to the interface that will be used to send to the destination (the "outgoing" interface). Add a sysctl to enable this behaviour. Signed-off-by: Erik Kline <ek@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>

* vxlan: Flow based tunnelingThomas Graf2015-07-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Allows putting a VXLAN device into a new flow-based mode in which skbs with a ip_tunnel_info dst metadata attached will be encapsulated according to the instructions stored in there with the VXLAN device defaults taken into consideration. Similar on the receive side, if the VXLAN_F_COLLECT_METADATA flag is set, the packet processing will populate a ip_tunnel_info struct for each packet received and attach it to the skb using the new metadata dst. The metadata structure will contain the outer header and tunnel header fields which have been stripped off. Layers further up in the stack such as routing, tc or netfitler can later match on these fields and perform forwarding. It is the responsibility of upper layers to ensure that the flag is set if the metadata is needed. The flag limits the additional cost of metadata collecting based on demand. This prepares the VXLAN device to be steered by the routing and other subsystems which allows to support encapsulation for a large number of tunnel endpoints and tunnel ids through a single net_device which improves the scalability. It also allows for OVS to leverage this mode which in turn allows for the removal of the OVS specific VXLAN code. Because the skb is currently scrubed in vxlan_rcv(), the attachment of the new dst metadata is postponed until after scrubing which requires the temporary addition of a new member to vxlan_metadata. This member is removed again in a later commit after the indirect VXLAN receive API has been removed.

Both structures are kernel internal and will stay that way. Their members are exposed to user space through individual Netlink attributes by OVS.

* bpf: introduce bpf_skb_vlan_push/pop() helpersAlexei Starovoitov2015-07-20
| | | | | | | | | | | | | | | | | | | | | | | | | | Allow eBPF programs attached to TC qdiscs call skb_vlan_push/pop via helper functions. These functions may change skb->data/hlen which are cached by some JITs to improve performance of ld_abs/ld_ind instructions. Therefore JITs need to recognize bpf_skb_vlan_push/pop() calls, re-compute header len and re-cache skb->data/hlen back into cpu registers. Note, skb->data/hlen are not directly accessible from the programs, so any changes to skb->data done either by these helpers or by other TC actions are safe. eBPF JIT supported by three architectures: - arm64 JIT is using bpf_load_pointer() without caching, so it's ok as-is. - x64 JIT re-caches skb->data/hlen unconditionally after vlan_push/pop calls (experiments showed that conditional re-caching is slower). - s390 JIT falls back to interpreter for now when bpf_skb_vlan_push() is present in the program (re-caching is tbd). These helpers allow more scalable handling of vlan from the programs. Instead of creating thousands of vlan netdevs on top of eth0 and attaching TC+ingress+bpf to all of them, the program can be attached to eth0 directly and manipulate vlans as necessary.

Jacob provides several patches to clarify the intended way to implement both SIOCSHWTSTAMP and ethtool's get_ts_info(). It is okay to support the specific filters in SIOCSHWTSTAMP by upscaling them to the generic filters. Alex Duyck provides a igb patch to pull the time stamp from the fragment before it gets added to the skb, to avoid a possible issue in which the fragment can possibly be less than IGB_RX_HDR_LEN due to the time stamp being pulled after the copybreak check. Also provides a ixgbevf patch to fold the ixgbevf_pull_tail() call into ixgbevf_add_rx_frag(), which gives the advantage that the fragment does not have to be modified after it is added to the skb. Fan provides patches for ixgbe/ixgbevf to set the receive hash type based on receive descriptor RSS type. Todd provides a fix for igb where on check for link on any media other than copper was not being detected since it was looking on the incorrect PHY page (due to the page being used gets switched before the function to check link gets executed). ==================== Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds some clarification about the intended way to implement both SIOCSHWTSTAMP and ethtool's get_ts_info. The HWTSTAMP API has several Rx filters which are very specific, as well as more general filters. The specific filters really only exist to support some broken hardware which can't fully implement the generic filters. This patch adds clarification that it is okay to support the specific filters in SIOCSHWTSTAMP by upscaling them to the generic filters. In addition, update the header for ethtool_ts_info to specify that drivers ought to only report the filters they support without upscaling in this manner.

|/ | | | | | | | | | | | | | | | | | | | | It would be very useful to retrieve the net_cls's classid from an eBPF program to allow for a more fine-grained classification, it could be directly used or in conjunction with additional policies. I.e. docker, but also tooling such as cgexec, can easily run applications via net_cls cgroups: cgcreate -g net_cls:/foo echo 42 > foo/net_cls.classid cgexec -g net_cls:foo <prog> Thus, their respecitve classid cookie of foo can then be looked up on the egress path to apply further policies.

There are two redeeming properties that made me merge this: - It's a trivial amount of code: since we wrap host/guest accesses anyway, almost all of it is well hidden from drivers. - Sane platforms would never set flags like VHOST_CROSS_ENDIAN_LEGACY, and when it's clear, there's zero overhead (as some point it was tested by compiling with and without the patches, got the same stripped binary).

It can also be used to handle the special case of a legacy little-endian device implemented by a big-endian host. Let's add a flag and ioctls for big-endian devices as well. If both flags are set, little-endian wins. Since this is isn't a common usecase, the feature is controlled by a kernel config option (not set by default).

Since it is a relatively rare situation, the feature availability is controlled by a kernel config option (not set by default). The vq->is_le boolean field is added to cache the endianness to be used for ring accesses. It defaults to native endian, as expected by legacy virtio devices. When the ring gets active, we force little endian if the device is modern. When the ring is deactivated, we revert to the native endian default. If cross-endian was compiled in, a vq->user_be boolean field is added so that userspace may request a specific endianness. This field is used to override the default when activating the ring of a legacy device. It has no effect on modern devices.

After registering NVDIMMs the NFIT driver then registers "region" devices. A libnvdimm-region defines an access mode and the boundaries of persistent memory media. A region may span multiple NVDIMMs that are interleaved by the hardware memory controller. In turn, a libnvdimm-region can be carved into a "namespace" device and bound to the PMEM or BLK driver which will attach a Linux block device (disk) interface to the memory. PMEM: Initially merged in v4.1 this driver for contiguous spans of persistent memory address ranges is re-worked to drive PMEM-namespaces emitted by the libnvdimm-core. In this update the PMEM driver, on x86, gains the ability to assert that writes to persistent memory have been flushed all the way through the caches and buffers in the platform to persistent media. See memcpy_to_pmem() and wmb_pmem(). BLK: This new driver enables access to persistent memory media through "Block Data Windows" as defined by the NFIT. The primary difference of this driver to PMEM is that only a small window of persistent memory is mapped into system address space at any given point in time. Per-NVDIMM windows are reprogrammed at run time, per-I/O, to access different portions of the media. BLK-mode, by definition, does not support DAX. BTT: This is a library, optionally consumed by either PMEM or BLK, that converts a byte-accessible namespace into a disk with atomic sector update semantics (prevents sector tearing on crash or power loss). The sinister aspect of sector tearing is that most applications do not know they have a atomic sector dependency. At least today's disk's rarely ever tear sectors and if they do one almost certainly gets a CRC error on access. NVDIMMs will always tear and always silently. Until an application is audited to be robust in the presence of sector-tearing the usage of BTT is recommended.

Note that PMEM allocations grow forwards from the start of an interleave set (lowest dimm-physical-address (DPA)). BLK-namespaces that alias with a PMEM interleave set will grow allocations backward from the highest DPA.

ACPI 6 introduces the concept that a given nvdimm may simultaneously offer multiple access modes to its media through direct PMEM load/store access, or windowed BLK mode. Existing nvdimms mostly implement a PMEM interface, some offer a BLK-like mode, but never both as ACPI 6 defines. If an nvdimm is single interfaced, then there is no need for dimm metadata labels. For these devices we can take the region boundaries directly to create a child namespace device (nd_namespace_io).

This is a simple association of a nd-device-type number with a driver that has a bitmask of supported device types. To facilitate userspace bind/unbind operations 'modalias' and 'devtype', that also appear in the uevent, are added as generic sysfs attributes for all nvdimm devices. The reason for the device-type number is to support sub-types within a given parent devtype, be it a vendor-specific sub-type or otherwise. * The first consumer of this infrastructure is the driver for dimm devices. It simply uses control messages to retrieve and store the configuration-data image (label set) from each dimm. Note: nd_device_register() arranges for asynchronous registration of nvdimm bus devices by default.

However, some nvdimm_bus instances, particularly the ACPI.NFIT bus, define a small set of messages that can be passed to the platform. For convenience we derive the initial libnvdimm-ioctl command formats directly from the NFIT DSM Interface Example formats. ND_CMD_SMART: media health and diagnostics ND_CMD_GET_CONFIG_SIZE: size of the label space ND_CMD_GET_CONFIG_DATA: read label space ND_CMD_SET_CONFIG_DATA: write label space ND_CMD_VENDOR: vendor-specific command passthrough ND_CMD_ARS_CAP: report address-range-scrubbing capabilities ND_CMD_ARS_START: initiate scrubbing ND_CMD_ARS_STATUS: report on scrubbing state ND_CMD_SMART_THRESHOLD: configure alarm thresholds for smart events If a platform later defines different commands than this set it is straightforward to extend support to those formats. Most of the commands target a specific dimm. However, the address-range-scrubbing commands target the bus. The 'commands' attribute in sysfs of an nvdimm_bus, or nvdimm, enumerate the supported commands for that object.

I've one other new driver from freescale on my radar, it's been posted and reviewed, I'd just like to get someone to give it a last look, so maybe I'll send it or maybe I'll leave it. There is no major nouveau changes in here, Ben was working on something big, and we agreed it was a bit late, there wasn't anything else he considered urgent to merge. There might be another msm pull for some bits that are waiting on arm-soc, I'll see how we time it. This touches some "of" stuff, acks are in place except for the fixes to the build in various configs,t hat I just applied. Summary: New drivers: - virtio-gpu: KMS only pieces of driver for virtio-gpu in qemu. This is just the first part of this driver, enough to run unaccelerated userspace on. As qemu merges more we'll start adding the 3D features for the virgl 3d work. - amdgpu: a new driver from AMD to driver their newer GPUs. (VI+) It contains a new cleaner userspace API, and is a clean break from radeon moving forward, that AMD are going to concentrate on. It also contains a set of register headers auto generated from AMD internal database. core: - atomic modesetting API completed, enabled by default now. - Add support for mode_id blob to atomic ioctl to complete interface. - bunch of Displayport MST fixes - lots of misc fixes. panel: - new simple panels - fix some long-standing build issues with bridge drivers radeon: - VCE1 support - add a GPU reset counter for userspace - lots of fixes. amdkfd: - H/W debugger support module - static user-mode queues - support killing all the waves when a process terminates - use standard DECLARE_BITMAP i915: - Add Broxton support - S3, rotation support for Skylake - RPS booting tuning - CPT modeset sequence fixes - ns2501 dither support - enable cmd parser on haswell - cdclk handling fixes - gen8 dynamic pte allocation - lots of atomic conversion work exynos: - Add atomic modesetting support - Add iommu support - Consolidate drm driver initialization - and MIC, DECON and MIPI-DSI support for exynos5433 omapdrm: - atomic modesetting support (fixes lots of things in rewrite) tegra: - DP aux transaction fixes - iommu support fix msm: - adreno a306 support - various dsi bits - various 64-bit fixes - NV12MT support rcar-du: - atomic and misc fixes sti: - fix HDMI timing complaince tilcdc: - use drm component API to access tda998x driver - fix module unloading qxl: - stability fixes" * 'drm-next' of git://people.freedesktop.org/~airlied/linux: (872 commits) drm/nouveau: Pause between setting gpu to D3hot and cutting the power drm/dp/mst: close deadlock in connector destruction. drm: Always enable atomic API drm/vgem: Set unique to "vgem" of: fix a build error to of_graph_get_endpoint_by_regs function drm/dp/mst: take lock around looking up the branch device on hpd irq drm/dp/mst: make sure mst_primary mstb is valid in work function of: add EXPORT_SYMBOL for of_graph_get_endpoint_by_regs ARM: dts: rename the clock of MIPI DSI 'pll_clk' to 'sclk_mipi' drm/atomic: Don't set crtc_state->enable manually drm/exynos: dsi: do not set TE GPIO direction by input drm/exynos: dsi: add support for MIC driver as a bridge drm/exynos: dsi: add support for Exynos5433 drm/exynos: dsi: make use of array for clock access drm/exynos: dsi: make use of driver data for static values drm/exynos: dsi: add macros for register access drm/exynos: dsi: rename pll_clk to sclk_clk drm/exynos: mic: add MIC driver of: add helper for getting endpoint node of specific identifiers drm/exynos: add Exynos5433 decon driver ...
