2017-08-08media: drop use of MEDIA_API_VERSIONHans Verkuil1-2/+3
Set media_version to LINUX_VERSION_CODE, just as we did for driver_version. Nobody ever rememebers to update the version number, but LINUX_VERSION_CODE will always be updated. Move the MEDIA_API_VERSION define to the ifndef __KERNEL__ section of the media.h header. That way kernelspace can't accidentally start to use it again.

2017-08-08KVM: add spinlock optimization frameworkLongpeng(Mike)1-1/+2
If a vcpu exits due to request a user mode spinlock, then the spinlock-holder may be preempted in user mode or kernel mode. (Note that not all architectures trap spin loops in user mode, only AMD x86 and ARM/ARM64 currently do). But if a vcpu exits in kernel mode, then the holder must be preempted in kernel mode, so we should choose a vcpu in kernel mode as a more likely candidate for the lock holder. This introduces kvm_arch_vcpu_in_kernel() to decide whether the vcpu is in kernel-mode when it's preempted. kvm_vcpu_on_spin's new argument says the same of the spinning VCPU.

2017-08-07net: switchdev: Remove bridge bypass support from switchdevArkadi Sharshevsky1-75/+0
Currently the bridge port flags, vlans, FDBs and MDBs can be offloaded through the bridge code, making the switchdev's SELF bridge bypass implementation to be redundant. This implies several changes: - No need for dump infra in switchdev, DSA's special case is handled privately. - Remove obj_dump from switchdev_ops. - FDBs are removed from obj_add/del routines, due to the fact that they are offloaded through the bridge notification chain. - The switchdev_port_bridge_xx() and switchdev_port_fdb_xx() functions can be removed.

2017-08-07ipv6: sr: define core operations for seg6local lightweight tunnelDavid Lebrun4-0/+77
This patch implements a new type of lightweight tunnel named seg6local. A seg6local lwt is defined by a type of action and a set of parameters. The action represents the operation to perform on the packets matching the lwt's route, and is not necessarily an encapsulation. The set of parameters are arguments for the processing function. Each action is defined in a struct seg6_action_desc within seg6_action_table[]. This structure contains the action, mandatory attributes, the processing function, and a static headroom size required by the action. The mandatory attributes are encoded as a bitmask field. The static headroom is set to a non-zero value when the processing function always add a constant number of bytes to the skb (e.g. the header size for encapsulations). To facilitate rtnetlink-related operations such as parsing, fill_encap, and cmp_encap, each type of action parameter is associated to three function pointers, in seg6_action_params[]. All actions defined in seg6_local.h are detailed in [1].

2017-08-07bpf: add support for sys_enter_* and sys_exit_* tracepointsYonghong Song1-0/+12
Currently, bpf programs cannot be attached to sys_enter_* and sys_exit_* style tracepoints. The iovisor/bcc issue #748 (https://github.com/iovisor/bcc/issues/748) documents this issue. For example, if you try to attach a bpf program to tracepoints syscalls/sys_enter_newfstat, you will get the following error: # ./tools/trace.py t:syscalls:sys_enter_newfstat Ioctl(PERF_EVENT_IOC_SET_BPF): Invalid argument Failed to attach BPF to tracepoint The main reason is that syscalls/sys_enter_* and syscalls/sys_exit_* tracepoints are treated differently from other tracepoints and there is no bpf hook to it. This patch adds bpf support for these syscalls tracepoints by . permitting bpf attachment in ioctl PERF_EVENT_IOC_SET_BPF . calling bpf programs in perf_syscall_enter and perf_syscall_exit The legality of bpf program ctx access is also checked. Function trace_event_get_offsets returns correct max offset for each specific syscall tracepoint, which is compared against the maximum offset access in bpf program.

Scsi_cmnd is an unsuitable argument for eh_device_reset_handler(), eh_target_reset_handler(), and eh_host_reset_handler() which do not have the scope of one single SCSI command. These callbacks tend to use fc_block_scsi_eh() requiring scsi_cmnd. In order to start decoupling above eh callbacks from scsi_cmnd, introduce a new variant of the function called fc_block_rport() taking an fc_rport as argument.

Rework the ACPI IORT kernel API to make sure they can accommodate the DMA set-up required by firmware.

Some devices have limited addressing capabilities and cannot reference the whole memory address space while carrying out DMA operations (eg some devices with bus address bits range smaller than system bus - which prevents them from using bus addresses that are otherwise valid for the system). The ACPI _DMA object allows bus devices to define the DMA window that is actually addressable by devices that sit upstream the bus, therefore providing a means to parse and initialize the devices DMA masks and addressable DMA range size. By relying on the generic ACPI kernel layer to retrieve and parse resources, introduce ACPI core code to parse the _DMA object.

When mlx5_ib registers itself to mlx5_core as an interface, it will call mlx5_add_device which will call mlx5_ib interface add callback, in case the latter successfully returns, only then mlx5_core will add it to the interface list and async events will be forwarded to mlx5_ib. Between mlx5_ib interface add callback and mlx5_core adding the mlx5_ib interface to its devices list, arriving mlx5_core events can be missed by the new mlx5_ib registering interface. In other words: thread 1: mlx5_ib: mlx5_register_interface(dev) thread 1: mlx5_core: mlx5_add_device(dev) thread 1: mlx5_core: ctx = dev->add => (mlx5_ib)->mlx5_ib_add thread 2: mlx5_core_event: **new event arrives, forward to dev_list thread 1: mlx5_core: add_ctx_to_dev_list(ctx) /* previous event was missed by the new interface.*/ It is ok to miss events before dev->add (mlx5_ib)->mlx5_ib_add_device but not after. We fix this race by accumulating the events that come between the ib_register_device (inside mlx5_add_device->(dev->add)) till the adding to the list completes and fire them to the new registering interface after that.

2017-08-07net/mlx5: Separate between E-Switch and MPFSSaeed Mahameed1-0/+2
Multi-Physical Function Switch (MPFs) is required for when multi-PF configuration is enabled to allow passing user configured unicast MAC addresses to the requesting PF. Before this patch eswitch.c used to manage the HW MPFS l2 table, E-Switch always (regardless of sriov) enabled vport(0) (NIC PF) vport's contexts update on unicast mac address list changes, to populate the PF's MPFS L2 table accordingly. In downstream patch we would like to allow compiling the driver without E-Switch functionalities, for that we move MPFS l2 table logic out of eswitch.c into its own file, and provide Kconfig flag (MLX5_MPFS) to allow compiling out MPFS for those who don't want Multi-PF support. NIC PF netdevice will now directly update MPFS l2 table via the new MPFS API. VF netdevice has no access to MPFS L2 table, so E-Switch will remain responsible of updating its MPFS l2 table on behalf of its VFs. Due to this change we also don't require enabling vport(0) (PF vport) unicast mac changes events anymore, for when SRIOV is not enabled. Which means E-Switch is now activated only on SRIOV activation, and not required otherwise.

2017-08-06sctp: remove the typedef sctp_subtype_tXin Long2-15/+16
This patch is to remove the typedef sctp_subtype_t, and replace with union sctp_subtype in the places where it's using this typedef. Note that it doesn't fix many indents although it should, as sctp_disposition_t's removal would mess them up again. So better to fix them when removing sctp_disposition_t in later patch.
