2018-07-24media: v4l: Add support for STD ioctls on subdev nodesNiklas Söderlund1-0/+4
There is no way to control the standard of subdevices which are part of a media device. The ioctls which exists all target video devices explicitly and the idea is that the video device should talk to the subdevice. For subdevices part of a media graph this is not possible and the standard must be controlled on the subdev device directly. Add four new ioctls to be able to directly interact with subdevices and control the video standard; VIDIOC_SUBDEV_ENUMSTD, VIDIOC_SUBDEV_G_STD, VIDIOC_SUBDEV_S_STD and VIDIOC_SUBDEV_QUERYSTD.

2018-07-24IB/mlx5: Introduce driver create and destroy flow methodsYishai Hadas1-0/+17
Introduce driver create and destroy flow methods on the uverbs flow object. This allows the driver to get its specific device attributes to match the underlay specification while still using the generic ib_flow object for cleanup and code sharing. The IB object's attributes are set via the ib_set_flow() helper function. The specific implementation for the given specification is added in downstream patches.

2018-07-23rds: Extend RDS API for IPv6 supportKa-Cheong Poon1-2/+67
There are many data structures (RDS socket options) used by RDS apps which use a 32 bit integer to store IP address. To support IPv6, struct in6_addr needs to be used. To ensure backward compatibility, a new data structure is introduced for each of those data structures which use a 32 bit integer to represent an IP address. And new socket options are introduced to use those new structures. This means that existing apps should work without a problem with the new RDS module. For apps which want to use IPv6, those new data structures and socket options can be used. IPv4 mapped address is used to represent IPv4 address in the new data structures. v4: Revert changes to SO_RDS_TRANSPORT Signed-off-by: Ka-Cheong Poon <ka-cheong.poon@oracle.com> Acked-by: Santosh Shilimkar <santosh.shilimkar@oracle.com> Signed-off-by: David S.

2018-07-23net: bridge: add support for backup portNikolay Aleksandrov1-0/+1
This patch adds a new port attribute - IFLA_BRPORT_BACKUP_PORT, which allows to set a backup port to be used for known unicast traffic if the port has gone carrier down. The backup pointer is rcu protected and set only under RTNL, a counter is maintained so when deleting a port we know how many other ports reference it as a backup and we remove it from all. Also the pointer is in the first cache line which is hot at the time of the check and thus in the common case we only add one more test. The backup port will be used only for the non-flooding case since it's a part of the bridge and the flooded packets will be forwarded to it anyway. To remove the forwarding just send a 0/non-existing backup port. This is used to avoid numerous scalability problems when using MLAG most notably if we have thousands of fdbs one would need to change all of them on port carrier going down which takes too long and causes a storm of fdb notifications (and again when the port comes back up). In a Multi-chassis Link Aggregation setup usually hosts are connected to two different switches which act as a single logical switch. Those switches usually have a control and backup link between them called peerlink which might be used for communication in case a host loses connectivity to one of them. We need a fast way to failover in case a host port goes down and currently none of the solutions (like bond) cannot fulfill the requirements because the participating ports are actually the "master" devices and must have the same peerlink as their backup interface and at the same time all of them must participate in the bridge device. As Roopa noted it's normal practice in routing called fast re-route where a precalculated backup path is used when the main one is down. Another use case of this is with EVPN, having a single vxlan device which is backup of every port. Due to the nature of master devices it's not currently possible to use one device as a backup for many and still have all of them participate in the bridge (which is master itself). More detailed information about MLAG is available at the link below. https://docs.cumulusnetworks.com/display/DOCS/Multi-Chassis+Link+Aggregation+-+MLAG Further explanation and a diagram by Roopa: Two switches acting in a MLAG pair are connected by the peerlink interface which is a bridge port. the config on one of the switches looks like the below. The other switch also has a similar config. eth0 is connected to one port on the server. And the server is connected to both switches. br0 -- team0---eth0 | -- switch-peerlink Signed-off-by: Nikolay Aleksandrov <nikolay@cumulusnetworks.com> Signed-off-by: David S.

2018-07-20drm/i915: Only force GGTT coherency w/a on required chipsetsChris Wilson1-0/+22
Not all chipsets have an internal buffer delaying the visibility of writes via the GGTT being visible by other physical paths, but we use a very heavy workaround for all. We only need to apply that workarounds to the chipsets we know suffer from the delay and the resulting coherency issue. Similarly, the same inconsistent coherency fouls up our ABI promise that a write into a mmap_gtt is immediately visible to others. Since the HW has made that a lie, let userspace know when that contract is broken. (Not that userspace would want to use mmap_gtt on those chipsets for other performance reasons...)

2018-07-19MIPS: Add DSP ASE regset supportMaciej W. Rozycki1-0/+1
Define an NT_MIPS_DSP core file note type and implement a corresponding regset holding the DSP ASE register context, following the layout of the `mips_dsp_state' structure, except for the DSPControl register stored as a 64-bit rather than 32-bit quantity in a 64-bit note. The lack of DSP ASE register saving to core files can be considered a design flaw with commit e50c0a8fa60d ("Support the MIPS32 / MIPS64 DSP ASE."), leading to an incomplete state being saved. Consequently no DSP ASE regset has been created with commit 7aeb753b5353 ("MIPS: Implement task_user_regset_view."), when regset support was added to the MIPS port. Additionally there is no way for ptrace(2) to correctly access the DSP accumulator registers in n32 processes with the existing interfaces. This is due to 32-bit truncation of data passed with PTRACE_PEEKUSR and PTRACE_POKEUSR requests, which cannot be avoided owing to how the data types for ptrace(3) have been defined. This new NT_MIPS_DSP regset fills the missing interface gap. [paul.burton@mips.com: - Change NT_MIPS_DSP to 0x800 to avoid conflict with NT_VMCOREDD introduced by commit 2724273e8fd0 ("vmcore: add API to collect hardware dump in second kernel"). - Drop stable tag.

This now produces the following records when parsing IMA policy's rules: type=UNKNOWN[1807] msg=audit(1527888965.738:320): action=audit \ func=MMAP_CHECK mask=MAY_EXEC res=1 type=UNKNOWN[1807] msg=audit(1527888965.738:320): action=audit \ func=FILE_CHECK mask=MAY_READ res=1 type=SYSCALL msg=audit(1527888965.738:320): arch=c000003e syscall=1 \ success=yes exit=17 a0=1 a1=55bcfcca9030 a2=11 a3=7fcc1b55fb38 \ items=0 ppid=1567 pid=1601 auid=0 uid=0 gid=0 euid=0 suid=0 \ fsuid=0 egid=0 sgid=0 fsgid=0 tty=tty2 ses=2 comm="echo" \ exe="/usr/bin/echo" \ subj=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 key=(null) Signed-off-by: Stefan Berger <stefanb@linux.vnet.ibm.com> Acked-by: Paul Moore <paul@paul-moore.com> Signed-off-by: Mimi Zohar <zohar@linux.vnet.ibm.com>

glibc uses a different defintion of sigset_t than the kernel does, and the current version would pull in both.

A dial is a tool you place on a multitouch surface which reports its orientation or a relative angle of rotation when rotating its knob. Some examples are the Dell Totem (on the Canvas 27"), the Microsoft Dial, or the Griffin Powermate, though the later can't be put on a touch surface. We give some extra space to account for other types of fingers if we need (MT_TOOL_THUMB) Slightly change the documentation to not make it mandatory to update each MT_TOOL we add.

This patch adds support for the Processig Units defined in the UAC3 spec. The main difference with the previous specs is the lack of on/off switches in the controls for these units and the addiction of the new Multi Function Processing Unit. The current version of the UAC3 spec doesn't define any useful controls for the new Multi Function Processing Unit so no control will get created once this unit is parsed.

2018-07-15fpga: dfl: afu: add DFL_FPGA_PORT_DMA_MAP/UNMAP ioctls supportWu Hao1-0/+37
DMA memory regions are required for Accelerated Function Unit (AFU) usage. These two ioctls allow user space applications to map user memory regions for dma, and unmap them after use. Iova is returned from driver to user space application via DFL_FPGA_PORT_DMA_MAP ioctl. Application needs to unmap it after use, otherwise, driver will unmap them in device file release operation. Each AFU has its own rb tree to keep track of its mapped DMA regions. Ioctl interfaces: * DFL_FPGA_PORT_DMA_MAP Do the dma mapping per user_addr and length provided by user. Return iova in provided struct dfl_fpga_port_dma_map. * DFL_FPGA_PORT_DMA_UNMAP Unmap the dma region per iova provided by user.

Partial Reconfiguration (PR) is the most important function for FME. It allows reconfiguration for given Port/Accelerated Function Unit (AFU). It creates platform devices for fpga-mgr, fpga-regions and fpga-bridges, and invokes fpga-region's interface (fpga_region_program_fpga) for PR operation once PR request received via ioctl. Below user space interface is exposed by this sub feature. Ioctl interface: * DFL_FPGA_FME_PORT_PR Do partial reconfiguration per information from userspace, including target port(AFU), buffer size and address info. It returns error code to userspace if failed. For detailed PR error information, user needs to read fpga-mgr's status sysfs interface.

Daniel Borkmann says: ==================== pull-request: bpf-next 2018-07-15 The following pull-request contains BPF updates for your *net-next* tree. The main changes are: 1) Various different arm32 JIT improvements in order to optimize code emission and make the JIT code itself more robust, from Russell. 2) Support simultaneous driver and offloaded XDP in order to allow for advanced use-cases where some work is offloaded to the NIC and some to the host. Also add ability for bpftool to load programs and maps beyond just the cgroup case, from Jakub. 3) Add BPF JIT support in nfp for multiplication as well as division. For the latter in particular, it uses the reciprocal algorithm to emulate it, from Jiong. 4) Add BTF pretty print functionality to bpftool in plain and JSON output format, from Okash. 5) Add build and installation to the BPF helper man page into bpftool, from Quentin. 6) Add a TCP BPF callback for listening sockets which is triggered right after the socket transitions to TCP_LISTEN state, from Andrey. 7) Add a new cgroup tree command to bpftool which iterates over the whole cgroup tree and prints all attached programs, from Roman. 8) Improve xdp_redirect_cpu sample to support parsing of double VLAN tagged packets, from Jesper. ==================== Signed-off-by: David S.

2018-07-15bpf: Add BPF_SOCK_OPS_TCP_LISTEN_CBAndrey Ignatov1-0/+3
Add new TCP-BPF callback that is called on listen(2) right after socket transition to TCP_LISTEN state. It fills the gap for listening sockets in TCP-BPF. For example BPF program can set BPF_SOCK_OPS_STATE_CB_FLAG when socket becomes listening and track later transition from TCP_LISTEN to TCP_CLOSE with BPF_SOCK_OPS_STATE_CB callback. Before there was no way to do it with TCP-BPF and other options were much harder to work with. E.g. socket state tracking can be done with tracepoints (either raw or regular) but they can't be attached to cgroup and their lifetime has to be managed separately.
