2022-04-23cxl/mbox: Use type __u32 for mailbox payload sizesAlison Schofield1-7/+7
Payload sizes for mailbox commands are expected to be positive values coming from userspace. The documentation correctly describes these as always unsigned values. The mailbox and send structures that support the mailbox commands however, use __s32 types for the payloads. Replace __s32 with __u32 in the mailbox and send command structures and update usages. Kernel users of the interface already block all negative values and there is no known ability for userspace to have grown a dependency on submitting negative values to the kernel. The known user of the IOCTL, the CXL command line interface (cxl-cli) already enforces positive size values. A Smatch warning of a signedness uncovered this issue.

2022-04-22arm64/sme: Add ptrace support for ZAMark Brown1-0/+1
The ZA array can be read and written with the NT_ARM_ZA. Similarly to our interface for the SVE vector registers the regset consists of a header with information on the current vector length followed by an optional register data payload, represented as for signals as a series of horizontal vectors from 0 to VL/8 in the endianness independent format used for vectors. On get if ZA is enabled then register data will be provided, otherwise it will be omitted. On set if register data is provided then ZA is enabled and initialized using the provided data, otherwise it is disabled.

2022-04-22arm64/sme: Implement ptrace support for streaming mode SVE registersMark Brown1-0/+1
The streaming mode SVE registers are represented using the same data structures as for SVE but since the vector lengths supported and in use may not be the same as SVE we represent them with a new type NT_ARM_SSVE. Unfortunately we only have a single 16 bit reserved field available in the header so there is no space to fit the current and maximum vector length for both standard and streaming SVE mode without redefining the structure in a way the creates a complicatd and fragile ABI. Since FFR is not present in streaming mode it is read and written as zero. Setting NT_ARM_SSVE registers will put the task into streaming mode, similarly setting NT_ARM_SVE registers will exit it. Reads that do not correspond to the current mode of the task will return the header with no register data. For compatibility reasons on write setting no flag for the register type will be interpreted as setting SVE registers, though users can provide no register data as an alternative mechanism for doing so.

2022-04-18devlink: implement line card provisioningJiri Pirko1-0/+15
In order to be able to configure all needed stuff on a port/netdevice of a line card without the line card being present, introduce line card provisioning. Basically by setting a type, provisioning process will start and driver is supposed to create a placeholder for instances (ports/netdevices) for a line card type. Allow the user to query the supported line card types over line card get command. Then implement two netlink command SET to allow user to set/unset the card type. On the driver API side, add provision/unprovision ops and supported types array to be advertised. Upon provision op call, the driver should take care of creating the instances for the particular line card type. Introduce provision_set/clear() functions to be called by the driver once the provisioning/unprovisioning is done on its side. These helpers are not to be called directly due to the async nature of provisioning. Example: $ devlink port # No ports are listed $ devlink lc pci/0000:01:00.0: lc 1 state unprovisioned supported_types: 16x100G lc 2 state unprovisioned supported_types: 16x100G lc 3 state unprovisioned supported_types: 16x100G lc 4 state unprovisioned supported_types: 16x100G lc 5 state unprovisioned supported_types: 16x100G lc 6 state unprovisioned supported_types: 16x100G lc 7 state unprovisioned supported_types: 16x100G lc 8 state unprovisioned supported_types: 16x100G $ devlink lc set pci/0000:01:00.0 lc 8 type 16x100G $ devlink lc show pci/0000:01:00.0 lc 8 pci/0000:01:00.0: lc 8 state active type 16x100G supported_types: 16x100G $ devlink port pci/0000:01:00.0/0: type notset flavour cpu port 0 splittable false pci/0000:01:00.0/53: type eth netdev enp1s0nl8p1 flavour physical lc 8 port 1 splittable true lanes 4 pci/0000:01:00.0/54: type eth netdev enp1s0nl8p2 flavour physical lc 8 port 2 splittable true lanes 4 pci/0000:01:00.0/55: type eth netdev enp1s0nl8p3 flavour physical lc 8 port 3 splittable true lanes 4 pci/0000:01:00.0/56: type eth netdev enp1s0nl8p4 flavour physical lc 8 port 4 splittable true lanes 4 pci/0000:01:00.0/57: type eth netdev enp1s0nl8p5 flavour physical lc 8 port 5 splittable true lanes 4 pci/0000:01:00.0/58: type eth netdev enp1s0nl8p6 flavour physical lc 8 port 6 splittable true lanes 4 pci/0000:01:00.0/59: type eth netdev enp1s0nl8p7 flavour physical lc 8 port 7 splittable true lanes 4 pci/0000:01:00.0/60: type eth netdev enp1s0nl8p8 flavour physical lc 8 port 8 splittable true lanes 4 pci/0000:01:00.0/61: type eth netdev enp1s0nl8p9 flavour physical lc 8 port 9 splittable true lanes 4 pci/0000:01:00.0/62: type eth netdev enp1s0nl8p10 flavour physical lc 8 port 10 splittable true lanes 4 pci/0000:01:00.0/63: type eth netdev enp1s0nl8p11 flavour physical lc 8 port 11 splittable true lanes 4 pci/0000:01:00.0/64: type eth netdev enp1s0nl8p12 flavour physical lc 8 port 12 splittable true lanes 4 pci/0000:01:00.0/125: type eth netdev enp1s0nl8p13 flavour physical lc 8 port 13 splittable true lanes 4 pci/0000:01:00.0/126: type eth netdev enp1s0nl8p14 flavour physical lc 8 port 14 splittable true lanes 4 pci/0000:01:00.0/127: type eth netdev enp1s0nl8p15 flavour physical lc 8 port 15 splittable true lanes 4 pci/0000:01:00.0/128: type eth netdev enp1s0nl8p16 flavour physical lc 8 port 16 splittable true lanes 4 $ devlink lc set pci/0000:01:00.0 lc 8 notype Signed-off-by: Jiri Pirko <jiri@nvidia.com> Signed-off-by: Ido Schimmel <idosch@nvidia.com> Signed-off-by: David S.

USDTs are an abstraction built on top of uprobes, critical for tracing and BPF, and widely used in production applications, from Andrii Nakryiko. 2) While Andrii was adding support for x86{-64}-specific logic of parsing USDT argument specification, Ilya followed-up with USDT support for s390 architecture, from Ilya Leoshkevich. 3) Support name-based attaching for uprobe BPF programs in libbpf. The format supported is `u[ret]probe/binary_path:[raw_offset|function[+offset]]`, e.g. attaching to libc malloc can be done in BPF via SEC("uprobe/libc.so.6:malloc") now, from Alan Maguire. 4) Various load/store optimizations for the arm64 JIT to shrink the image size by using arm64 str/ldr immediate instructions. Also enable pointer authentication to verify return address for JITed code, from Xu Kuohai. 5) BPF verifier fixes for write access checks to helper functions, e.g. rd-only memory from bpf_*_cpu_ptr() must not be passed to helpers that write into passed buffers, from Kumar Kartikeya Dwivedi. 6) Fix overly excessive stack map allocation for its base map structure and buckets which slipped-in from cleanups during the rlimit accounting removal back then, from Yuntao Wang. 7) Extend the unstable CT lookup helpers for XDP and tc/BPF to report netfilter connection tracking tuple direction, from Lorenzo Bianconi. 8) Improve bpftool dump to show BPF program/link type names, Milan Landaverde. 9) Minor cleanups all over the place from various others. * https://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next: (63 commits) bpf: Fix excessive memory allocation in stack_map_alloc() selftests/bpf: Fix return value checks in perf_event_stackmap test selftests/bpf: Add CO-RE relos into linked_funcs selftests libbpf: Use weak hidden modifier for USDT BPF-side API functions libbpf: Don't error out on CO-RE relos for overriden weak subprogs samples, bpf: Move routes monitor in xdp_router_ipv4 in a dedicated thread libbpf: Allow WEAK and GLOBAL bindings during BTF fixup libbpf: Use strlcpy() in path resolution fallback logic libbpf: Add s390-specific USDT arg spec parsing logic libbpf: Make BPF-side of USDT support work on big-endian machines libbpf: Minor style improvements in USDT code libbpf: Fix use #ifdef instead of #if to avoid compiler warning libbpf: Potential NULL dereference in usdt_manager_attach_usdt() selftests/bpf: Uprobe tests should verify param/return values libbpf: Improve string parsing for uprobe auto-attach libbpf: Improve library identification for uprobe binary path resolution selftests/bpf: Test for writes to map key from BPF helpers selftests/bpf: Test passing rdonly mem to global func bpf: Reject writes for PTR_TO_MAP_KEY in check_helper_mem_access bpf: Check PTR_TO_MEM | MEM_RDONLY in check_helper_mem_access ... ==================== Link: https://lore.kernel.org/r/20220408231741.19116-1-daniel@iogearbox.net Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2022-04-08net-core: rx_otherhost_dropped to core_statsJeffrey Ji1-0/+5
Increment rx_otherhost_dropped counter when packet dropped due to mismatched dest MAC addr. An example when this drop can occur is when manually crafting raw packets that will be consumed by a user space application via a tap device.

2022-04-07virt: sevguest: Add support to get extended reportBrijesh Singh1-0/+13
Version 2 of GHCB specification defines Non-Automatic-Exit (NAE) to get extended guest report which is similar to the SNP_GET_REPORT ioctl. The main difference is related to the additional data that will be returned. That additional data returned is a certificate blob that can be used by the SNP guest user. The certificate blob layout is defined in the GHCB specification. The driver simply treats the blob as a opaque data and copies it to userspace.

The SNP_GET_DERIVED_KEY ioctl interface can be used by the SNP guest to ask the firmware to provide a key derived from a root key.

2022-04-07virt: Add SEV-SNP guest driverBrijesh Singh1-0/+50
The SEV-SNP specification provides the guest a mechanism to communicate with the PSP without risk from a malicious hypervisor who wishes to read, alter, drop or replay the messages sent. The driver uses snp_issue_guest_request() to issue GHCB SNP_GUEST_REQUEST or SNP_EXT_GUEST_REQUEST NAE events to submit the request to PSP. The PSP requires that all communication should be encrypted using key specified through a struct snp_guest_platform_data descriptor. Userspace can use SNP_GET_REPORT ioctl() to query the guest attestation report. See SEV-SNP spec section Guest Messages for more details.

2022-04-02tracing: mark user_events as BROKENSteven Rostedt (Google)1-116/+0
After being merged, user_events become more visible to a wider audience that have concerns with the current API. It is too late to fix this for this release, but instead of a full revert, just mark it as BROKEN (which prevents it from being selected in make config). Then we can work finding a better API. If that fails, then it will need to be completely reverted. To not have the code silently bitrot, still allow building it with COMPILE_TEST. And to prevent the uapi header from being installed, then later changed, and then have an old distro user space see the old version, move the header file out of the uapi directory. Surround the include with CONFIG_COMPILE_TEST to the current location, but when the BROKEN tag is taken off, it will use the uapi directory, and fail to compile. This is a good way to remind us to move the header back.

At the end of the patch series adding this batch of event channel acceleration features, finally add the feature bit which advertises them and document it all. For SCHEDOP_poll we need to wake a polling vCPU when a given port is triggered, even when it's masked — and we want to implement that in the kernel, for efficiency. So we want the kernel to know that it has sole ownership of event channel delivery. Thus, we allow userspace to make the 'promise' by setting the corresponding feature bit in its KVM_XEN_HVM_CONFIG call. As we implement SCHEDOP_poll bypass later, we will do so only if that promise has been made by userspace.

Now that the kernel is able to raise event channel events for itself, being able to do so for Windows guests is also going to be useful.

2022-04-02KVM: x86/xen: Support direct injection of event channel eventsDavid Woodhouse1-0/+3
This adds a KVM_XEN_HVM_EVTCHN_SEND ioctl which allows direct injection of events given an explicit { vcpu, port, priority } in precisely the same form that those fields are given in the IRQ routing table. Userspace is currently able to inject 2-level events purely by setting the bits in the shared_info and vcpu_info, but FIFO event channels are harder to deal with; we will need the kernel to take sole ownership of delivery when we support those.
