This adds a new ioctl, KVM_PPC_GET_CPU_CHAR, that gives userspace information about the underlying machine's level of vulnerability to the recently announced vulnerabilities CVE-2017-5715, CVE-2017-5753 and CVE-2017-5754, and whether the machine provides instructions to assist software to work around the vulnerabilities. The ioctl returns two u64 words describing characteristics of the CPU and required software behaviour respectively, plus two mask words which indicate which bits have been filled in by the kernel, for extensibility. The bit definitions are the same as for the new H_GET_CPU_CHARACTERISTICS hypercall. There is also a new capability, KVM_CAP_PPC_GET_CPU_CHAR, which indicates whether the new ioctl is available.

This is a series of patches, some of them initially by Franklin S Cooper Jr, which was picked up by Faiz Abbas. Faiz Abbas added some patches while working on this series, I contributed one as well. The first two patches add support to CAN device infrastructure to limit the bitrate of a CAN adapter if the used CAN-transceiver has a certain maximum bitrate. The remaining patches improve the m_can driver. They add support for bitrate limiting to the driver, clean up the driver and add support for runtime PM. ==================== Signed-off-by: David S.

2018-01-17net: sched: use block index as a handle instead of qdisc when block is sharedJiri Pirko1-0/+10
As the tcm_ifindex with value TCM_IFINDEX_MAGIC_BLOCK is invalid ifindex, use it to indicate that we work with block, instead of qdisc. So if tcm_ifindex is set to TCM_IFINDEX_MAGIC_BLOCK, tcm_parent is used to carry block_index. If the block is set to be shared between at least 2 qdiscs, it is forbidden to use the qdisc handle to add/delete filters. In that case, userspace has to pass block_index. Also, for dump of the filters, in case the block is shared in between at least 2 qdiscs, the each filter is dumped with tcm_ifindex value TCM_IFINDEX_MAGIC_BLOCK and tcm_parent set to block_index. That gives the user clear indication, that the filter belongs to a shared block and not only to one qdisc under which it is dumped.

Daniel Borkmann says: ==================== pull-request: bpf-next 2018-01-17 The following pull-request contains BPF updates for your *net-next* tree. The main changes are: 1) Add initial BPF map offloading for nfp driver. Currently only programs were supported so far w/o being able to access maps. Offloaded programs are right now only allowed to perform map lookups, and control path is responsible for populating the maps. BPF core infrastructure along with nfp implementation is provided, from Jakub. 2) Various follow-ups to Josef's BPF error injections. More specifically that includes: properly check whether the error injectable event is on function entry or not, remove the percpu bpf_kprobe_override and rather compare instruction pointer with original one, separate error-injection from kprobes since it's not limited to it, add injectable error types in order to specify what is the expected type of failure, and last but not least also support the kernel's fault injection framework, all from Masami. 3) Various misc improvements and cleanups to the libbpf Makefile. That is, fix permissions when installing BPF header files, remove unused variables and functions, and also install the libbpf.h header, from Jesper. 4) When offloading to nfp JIT and the BPF insn is unsupported in the JIT, then reject right at verification time. Also fix libbpf with regards to ELF section name matching by properly treating the program type as prefix. Both from Quentin. 5) Add -DPACKAGE to bpftool when including bfd.h for the disassembler. This is needed, for example, when building libfd from source as bpftool doesn't supply a config.h for bfd.h. Fix from Jiong. 6) xdp_convert_ctx_access() is simplified since it doesn't need to set target size during verification, from Jesper. 7) Let bpftool properly recognize BPF_PROG_TYPE_CGROUP_DEVICE program types, from Roman. 8) Various functions in BPF cpumap were not declared static, from Wei. 9) Fix a double semicolon in BPF samples, from Luis. ==================== Signed-off-by: David S.

2018-01-16Merge branch 'sev-v9-p2' of https://github.com/codomania/kvmPaolo Bonzini2-0/+232
This part of Secure Encrypted Virtualization (SEV) patch series focuses on KVM changes required to create and manage SEV guests. SEV is an extension to the AMD-V architecture which supports running encrypted virtual machine (VMs) under the control of a hypervisor. Encrypted VMs have their pages (code and data) secured such that only the guest itself has access to unencrypted version. Each encrypted VM is associated with a unique encryption key; if its data is accessed to a different entity using a different key the encrypted guest's data will be incorrectly decrypted, leading to unintelligible data. This security model ensures that hypervisor will no longer able to inspect or alter any guest code or data. The key management of this feature is handled by a separate processor known as the AMD Secure Processor (AMD-SP) which is present on AMD SOCs. The SEV Key Management Specification (see below) provides a set of commands which can be used by hypervisor to load virtual machine keys through the AMD-SP driver. The patch series adds a new ioctl in KVM driver (KVM_MEMORY_ENCRYPT_OP). The ioctl will be used by qemu to issue SEV guest-specific commands defined in Key Management Specification. The following links provide additional details: AMD Memory Encryption white paper: http://amd-dev.wpengine.netdna-cdn.com/wordpress/media/2013/12/AMD_Memory_Encryption_Whitepaper_v7-Public.pdf AMD64 Architecture Programmer's Manual: http://support.amd.com/TechDocs/24593.pdf SME is section 7.10 SEV is section 15.34 SEV Key Management: http://support.amd.com/TechDocs/55766_SEV-KM API_Specification.pdf KVM Forum Presentation: http://www.linux-kvm.org/images/7/74/02x08A-Thomas_Lendacky-AMDs_Virtualizatoin_Memory_Encryption_Technology.pdf SEV Guest BIOS support: SEV support has been add to EDKII/OVMF BIOS https://github.com/tianocore/edk2 Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2018-01-16can: dev: Add support for limiting configured bitrateFranklin S Cooper Jr1-0/+1
Various CAN or CAN-FD IP may be able to run at a faster rate than what the transceiver the CAN node is connected to. This can lead to unexpected errors. However, CAN transceivers typically have fixed limitations and provide no means to discover these limitations at runtime. Therefore, add support for a can-transceiver node that can be reused by other CAN peripheral drivers to determine for both CAN and CAN-FD what the max bitrate that can be used. If the user tries to configure CAN to pass these maximum bitrates it will throw an error. Also add support for reading bitrate_max via the netlink interface.

2018-01-14bpf: offload: add map offload infrastructureJakub Kicinski1-0/+1
BPF map offload follow similar path to program offload. At creation time users may specify ifindex of the device on which they want to create the map. Map will be validated by the kernel's .map_alloc_check callback and device driver will be called for the actual allocation. Map will have an empty set of operations associated with it (save for alloc and free callbacks). The real device callbacks are kept in map->offload->dev_ops because they have slightly different signatures. Map operations are called in process context so the driver may communicate with HW freely, msleep(), wait() etc. Map alloc and free callbacks are muxed via existing .ndo_bpf, and are always called with rtnl lock held. Maps and programs are guaranteed to be destroyed before .ndo_uninit (i.e. before unregister_netdev() returns). Map callbacks are invoked with bpf_devs_lock *read* locked, drivers must take care of exclusive locking if necessary. All offload-specific branches are marked with unlikely() (through bpf_map_is_dev_bound()), given that branch penalty will be negligible compared to IO anyway, and we don't want to penalize SW path unnecessarily.

drm/tegra: Changes for v4.16-rc1 The bulk of these changes are preparation work and addition of support for Tegra186. Currently only HDMI output (the primary output on Jetson TX2) is supported, but the hardware is also capable of doing DSI and DisplayPort. Tegra DRM now also uses the atomic commit helpers instead of the open- coded variant that was only doing half its job. As a bit of a byproduct of the Tegra186 support the driver also gained HDMI 2.0 as well as zpos property support. Along the way there are also a few patches to clean up a few things and fix minor issues. * tag 'drm/tegra/for-4.16-rc1-fixes' of git://anongit.freedesktop.org/tegra/linux: (51 commits) drm/tegra: dc: Properly cleanup overlay planes drm/tegra: dc: Fix possible_crtcs mask for planes drm/tegra: dc: Restore YUV overlay support drm/tegra: dc: Implement legacy blending drm/tegra: Correct timeout in tegra_syncpt_wait drm/tegra: gem: Correct iommu_map_sg() error checking drm/tegra: dc: Link DC1 to DC0 on Tegra20 drm/tegra: Fix non-debugfs builds drm/tegra: dpaux: Keep reset defaults for hybrid pad parameters drm/tegra: Mark Tegra186 display hub PM functions __maybe_unused drm/tegra: Use IOMMU groups gpu: host1x: Use IOMMU groups drm/tegra: Implement zpos property drm/tegra: dc: Remove redundant spinlock drm/tegra: dc: Use direct offset to plane registers drm/tegra: dc: Support more formats drm/tegra: fb: Force alpha formats drm/tegra: dpaux: Add Tegra186 support drm/tegra: dpaux: Implement runtime PM drm/tegra: sor: Support HDMI 2.0 modes ...
