2015-10-13nl80211: allow BSS data to include CLOCK_BOOTTIME timestampDmitry Shmidt1-0/+4
For location and connectivity services, userspace would often like to know the time when the BSS was last seen. The current "last seen" value is calculated in a way that makes it less useful, especially if the system suspended in the meantime. Add the ability for the driver to report a real CLOCK_BOOTTIME stamp that can then be reported to userspace (if present). Drivers wishing to use this must be converted to the new API to call cfg80211_inform_bss_data() or cfg80211_inform_bss_frame_data(). They need to ensure the reported value is accurate enough even when the frame might have been buffered in the device (e.g. firmware.)

2015-10-12efifb: Add support for 64-bit frame buffer addressesMatt Fleming1-2/+3
The EFI Graphics Output Protocol uses 64-bit frame buffer addresses but these get truncated to 32-bit by the EFI boot stub when storing the address in the 'lfb_base' field of 'struct screen_info'. Add a 'ext_lfb_base' field for the upper 32-bits of the frame buffer address and set VIDEO_TYPE_CAPABILITY_64BIT_BASE when the field is useable. It turns out that the reason no one has required this support so far is that there's actually code in tianocore to "downgrade" PCI resources that have option ROMs and 64-bit BARS from 64-bit to 32-bit to cope with legacy option ROMs that can't handle 64-bit addresses. The upshot is that basically all GOP devices in the wild use a 32-bit frame buffer address. Still, it is possible to build firmware that uses a full 64-bit GOP frame buffer address. Chad did, which led to him reporting this issue. Add support in anticipation of GOP devices using 64-bit addresses more widely, and so that efifb works out of the box when that happens.

Add BITMAP_MAJOR_CLUSTERED as 5, in order to prevent older kernels to assemble a clustered device. In order to maximize compatibility, the major version is set to BITMAP_MAJOR_CLUSTERED *only* if the bitmap is clustered. Added MD_FEATURE_CLUSTERED in order to return error for older kernels which would assemble MD even if the bitmap is corrupted.

2015-10-09nvme: move hardware structures out of the uapi version of nvme.hChristoph Hellwig2-589/+65
Currently all NVMe command and completion structures are exposed to userspace through the uapi version of nvme.h. They are not an ABI between the kernel and userspace, and will change in C-incompatible way for future versions of the spec. Move them to the kernel version of the file and rename the uapi header to nvme_ioctl.h so that userspace can easily detect the presence of the new clean header. Nvme-cli already carries a local copy of the header, so it won't be affected by this move.

2015-10-07openvswitch: Change CT_ATTR_FLAGS to CT_ATTR_COMMITJoe Stringer1-10/+4
Previously, the CT_ATTR_FLAGS attribute, when nested under the OVS_ACTION_ATTR_CT, encoded a 32-bit bitmask of flags that modify the semantics of the ct action. It's more extensible to just represent each flag as a nested attribute, and this requires no additional error checking to reject flags that aren't currently supported.

2015-10-07openvswitch: Extend ct_state match field to 32 bitsJoe Stringer1-4/+4
The ct_state field was initially added as an 8-bit field, however six of the bits are already being used and use cases are already starting to appear that may push the limits of this field. This patch extends the field to 32 bits while retaining the internal representation of 8 bits. This should cover forward compatibility of the ABI for the foreseeable future. This patch also reorders the OVS_CS_F_* bits to be sequential.

2015-10-04stm class: Introduce an abstraction for System Trace Module devicesAlexander Shishkin1-0/+50
A System Trace Module (STM) is a device exporting data in System Trace Protocol (STP) format as defined by MIPI STP standards. Examples of such devices are Intel(R) Trace Hub and Coresight STM. This abstraction provides a unified interface for software trace sources to send their data over an STM device to a debug host. In order to do that, such a trace source needs to be assigned a pair of master/channel identifiers that all the data from this source will be tagged with. The STP decoder on the debug host side will use these master/channel tags to distinguish different trace streams from one another inside one STP stream. This abstraction provides a configfs-based policy management mechanism for dynamic allocation of these master/channel pairs based on trace source-supplied string identifier. It has the flexibility of being defined at runtime and at the same time (provided that the policy definition is aligned with the decoding end) consistency. For userspace trace sources, this abstraction provides write()-based and mmap()-based (if the underlying stm device allows this) output mechanism. For kernel-side trace sources, we provide "stm_source" device class that can be connected to an stm device at run time.

2015-10-03sched, bpf: add helper for retrieving routing realmsDaniel Borkmann1-0/+7
Using routing realms as part of the classifier is quite useful, it can be viewed as a tag for one or multiple routing entries (think of an analogy to net_cls cgroup for processes), set by user space routing daemons or via iproute2 as an indicator for traffic classifiers and later on processed in the eBPF program. Unlike actions, the classifier can inspect device flags and enable netif_keep_dst() if necessary. tc actions don't have that possibility, but in case people know what they are doing, it can be used from there as well (e.g. via devs that must keep dsts by design anyway). If a realm is set, the handler returns the non-zero realm. User space can set the full 32bit realm for the dst.
