2022-03-21KVM: x86: Introduce KVM_CAP_DISABLE_QUIRKS2Oliver Upton
KVM_CAP_DISABLE_QUIRKS is irrevocably broken. The capability does not advertise the set of quirks which may be disabled to userspace, so it is impossible to predict the behavior of KVM. Worse yet, KVM_CAP_DISABLE_QUIRKS will tolerate any value for cap->args[0], meaning it fails to reject attempts to set invalid quirk bits. The only valid workaround for the quirky quirks API is to add a new CAP. Actually advertise the set of quirks that can be disabled to userspace so it can predict KVM's behavior. Reject values for cap->args[0] that contain invalid bits. Finally, add documentation for the new capability and describe the existing quirks.

2022-03-20bpf: Adjust BPF stack helper functions to accommodate skip > 0Namhyung Kim
Let's say that the caller has storage for num_elem stack frames. Then, the BPF stack helper functions walk the stack for only num_elem frames. This means that if skip > 0, one keeps only 'num_elem - skip' frames. This is because it sets init_nr in the perf_callchain_entry to the end of the buffer to save num_elem entries only. I believe it was because the perf callchain code unwound the stack frames until it reached the global max size (sysctl_perf_event_max_stack). However it now has perf_callchain_entry_ctx.max_stack to limit the iteration locally. This simplifies the code to handle init_nr in the BPF callstack entries and removes the confusion with the perf_event's __PERF_SAMPLE_CALLCHAIN_EARLY which sets init_nr to 0. Also change the comment on bpf_get_stack() in the header file to be more explicit what the return value means.

2022-03-18ptrace: Move setting/clearing ptrace_message into ptrace_stopEric W. Biederman
Today ptrace_message is easy to overlook as it not a core part of ptrace_stop. It has been overlooked so much that there are places that set ptrace_message and don't clear it, and places that never set it. So if you get an unlucky sequence of events the ptracer may be able to read a ptrace_message that does not apply to the current ptrace stop. Move setting of ptrace_message into ptrace_stop so that it always gets set before the stop, and always gets cleared after the stop. This prevents non-sense from being reported to userspace and makes ptrace_message more visible in the ptrace helper functions so that kernel developers can see it.

https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into char-misc-next Jonathan writes: First set of new device support, fixes, cleanups and features for IIO in 5.18 This cycle we had quite a few series that applied similar changes to lots of drivers. To keep this description manageable I have called those out in their own section rather than per driver. Particularly pleased to see the long running AFE precision series going in this cycle. Series includes some late breaking fixes. New device support * adi,ada4250 amplifier - New driver and dt bindings for this programmable gain amplifier. * adi,admv1014 microwave down-converter - New driver, dt bindings and some device specific ABI that may be generalized as more drivers for devices similar to this are added. * adi,admv4420 K Band down-converter. - New driver and dt bindings. * adi,adxl367 accelerometer driver. - New driver, dt-bindings + some new IIO ABI definitions to support reference magnitude events where an estimate of the acceleration due to gravity has been removed. - A few fixes as follow up patches. * adi,ltc2688 DAC with toggle and dither modes. - New driver and bindings. Includes some new driver specific (for now) ABI for handling toggle mode and the addition of a dither waveform to the DAC output. * AFE (analog front end) add support for additional types of analog device in front of an ADC. - RTD temperature sensors with dt bindings. - Temperature transducers wit dt bindings. - Related cleanup and features listed in other sections below. * maxim,ds3502 potentiometer. - Add support to ds1803 driver which required significant rework. * mediatek,mt2701-auxadc driver - Add mediatek,mt8186-auxadc - id table and chip specific info only. * semtech,sx9324, semtech,ax9360 - Substantial refactoring of sx9310 to extract core logic for reuse into a separate module - New driver using this supporting sx9324 proximity sensors. - New driver using this supporting sx9360 proximity sensors. * silan,sc7a20 - Compatible with the st,lis2dh (or nearly anyway) so add ID and chip specific info to enable support. Also silan vendor ID added for dt-bindings. Staging graduation * adi,ad7280a monitoring ADC for stacked lithium-ion batteries in electric cars and similar. - Substantial rework of driver required to bring inline with current IIO best practice. An unusual device in IIO so some interesting features we may see more of in future. Multiple driver/core cleanup - Use sysfs_emit() in simple locations where there is no path to change to various core created attributes. - Trivial white space fixes around inconsistency between space after { and before } in id tables. - Introduce new handling for fractional types to avoid repeated similar implementations. Use this in 3 drivers. Note this is also targeted at future use in the AFE driver and was motivated by discussions around the precision related work on that driver. - of related header cleanups - drop of*.h and add mod_devicetable.h as appropriate. - Move a number of symbol exports into IIO_* namespaces. Two categories, 1) Library used by multiple drivers e.g. st_sensors 2) Core driver module exporting functions used by bus specific modules. A few related cleanups in this set. - Switch from CONFIG_PM_* guards to new DEFINE_SIMPLE_DEV_PM_OPS() and similar to simplify drivers and take advantage of these new macros allowing the compiler to do the job or removing unused code without the need for __maybe_unused markings. Conversion of other drivers to these new macros ongoing. Features * adi,adf4350 - Switch from of specific to generic device properties enabling use with other firmware types. * adi,adx345 - Switch from of specific to generic device properties. - Add ACPI ID ADS0345 - Related driver cleanup. * adi,hmc425a - Switch from of specific to generic device properties. * afe analog rescaler driver - Wider range of types supported for scale. - Support offset. - Kunit tests. * atlas,ezo-sensor - Convert from of to device properties. * fsl,mma8452 - Support mount matrix. * infineon,dps310: - Add ACPI ID IFX3100. * invensense,mpu6050 - Convert to generic device properties. * maxim,ds1803 - Add out_raw_available before supporting more devices. - Convert from of specific to device properties. * samsung,ssp_sensors - Convert from of specific to device properties. * st,stm32-timer trigger - Convert from of specific to device properties. * ti,hdc101x - Add ACPI ID TXNW1010. * ti,tsc2046: - Add read_raw support to enable use of iio_hwmon and similar. Fixes / cleanup. * mailmap - Update for Cai Huoqing * MAINTAINERS - Fix Analog Devices related links. - Add entry for ADRF6780 - Add entry for ADMV1013 - Add entry for AD7293 - Add entry for ADMV8818 - Update files listed for adis-lib * iio core: - Fix wrong comment about current_mode being something a driver should ever access. - Use struct_size() rather than open coding in industrialio-hw-consumer * adi,axl355 - Use units.h definitions instead of local versions. * adi,adis-lib - Simplify *updated_bits() macro - Whitespace cleanup. * afe - Note many of these fixes only apply to particular configurations so the problems have probably not been seen in the wild, but will be visible with new usecases enabled this cycle. - Fix application of consumer scale for IIO_VAL_INT. - Apply a scale of 1 when no scale is provided. - Make best effort to establish a valid offset value for fractional cases. - Use s64 for scale calculations where parameters may be signed. - Tidy up include order. - Improve accuracy for small fractional sales - Reduce risk of integer overflow. * ams,as3935 - Use devm_delayed_work_autocancel() to replace open coded equivalent. * aspeed,adc - Fix wrong use of divider flag. * atmel,sama5d2-adc - Relax atmel,trigger-edge-type to optional. - Drop Ludovic Desroches from listed maintainers of the dt-binding inline with previous MAINTAINERS entry update. * fsl,mma8452 - Fix probing when i2c_device_id used. - dev_get_drvdata() on the iio_dev->dev, no longer returns iio_dev. Use dev_to_iio_dev() instead. Note the original path in here worked more by luck than design. * invensense,mpu6050 - Drop ACPI_PTR() protection to avoid an unused warning. - Use fact ACPI_COMPANION() returns null when ACPI_HANDLE() does to simplify handling. * motorola,cpcap-adc - Drop unused assignment. * qcom,spmi-adc - Fix wrong example of 'reg' in binding document. * renesas,rzg2l-adc - Trivial typo fix. * semtech,sx9360 - Fix wrong register handling for event generation. * st_sensors - Allow manual disabling of I2C or SPI module if not needed for a particular board.

2022-03-18rfkill: make new event layout opt-inJohannes Berg
Again new complaints surfaced that we had broken the ABI here, although previously all the userspace tools had agreed that it was their mistake and fixed it. Yet now there are cases (e.g. RHEL) that want to run old userspace with newer kernels, and thus are broken. Since this is a bit of a whack-a-mole thing, change the whole extensibility scheme of rfkill to no longer just rely on the message lengths, but instead require userspace to opt in via a new ioctl to a given maximum event size that it is willing to understand. By default, set that to RFKILL_EVENT_SIZE_V1 (8), so that the behaviour for userspace not calling the ioctl will look as if it's just running on an older kernel.

Adding support to call bpf_get_attach_cookie helper from kprobe programs attached with kprobe multi link. The cookie is provided by array of u64 values, where each value is paired with provided function address or symbol with the same array index. When cookie array is provided it's sorted together with addresses (check bpf_kprobe_multi_cookie_swap). This way we can find cookie based on the address in bpf_get_attach_cookie helper.

2022-03-17bpf: Add multi kprobe linkJiri Olsa
Adding new link type BPF_LINK_TYPE_KPROBE_MULTI that attaches kprobe program through fprobe API. The fprobe API allows to attach probe on multiple functions at once very fast, because it works on top of ftrace. On the other hand this limits the probe point to the function entry or return. The kprobe program gets the same pt_regs input ctx as when it's attached through the perf API. Adding new attach type BPF_TRACE_KPROBE_MULTI that allows attachment kprobe to multiple function with new link. User provides array of addresses or symbols with count to attach the kprobe program to. The new link_create uapi interface looks like: struct { __u32 flags; __u32 cnt; __aligned_u64 syms; __aligned_u64 addrs; } kprobe_multi; The flags field allows single BPF_TRACE_KPROBE_MULTI bit to create return multi kprobe.

Make it possible to change the port state in a given MSTI by extending the bridge port netlink interface (RTM_SETLINK on PF_BRIDGE).The proposed iproute2 interface would be: bridge mst set dev <PORT> msti <MSTI> state <STATE> Current states in all applicable MSTIs can also be dumped via a corresponding RTM_GETLINK.

2022-03-17net: bridge: mst: Multiple Spanning Tree (MST) modeTobias Waldekranz
Allow the user to switch from the current per-VLAN STP mode to an MST mode. Up to this point, per-VLAN STP states where always isolated from each other. This is in contrast to the MSTP standard (802.1Q-2018, Clause 13.5), where VLANs are grouped into MST instances (MSTIs), and the state is managed on a per-MSTI level, rather that at the per-VLAN level. Perhaps due to the prevalence of the standard, many switching ASICs are built after the same model. Therefore, add a corresponding MST mode to the bridge, which we can later add offloading support for in a straight-forward way. For now, all VLANs are fixed to MSTI 0, also called the Common Spanning Tree (CST). That is, all VLANs will follow the port-global state. Upcoming changes will make this actually useful by allowing VLANs to be mapped to arbitrary MSTIs and allow individual MSTI states to be changed.

2022-03-11gtp: Allow to create GTP device without FDsWojciech Drewek
Currently, when the user wants to create GTP device, he has to provide file handles to the sockets created in userspace (IFLA_GTP_FD0, IFLA_GTP_FD1). This behaviour is not ideal, considering the option of adding support for GTP device creation through ip link. Ip link application is not a good place to create such sockets. This patch allows to create GTP device without providing IFLA_GTP_FD0 and IFLA_GTP_FD1 arguments. If the user sets IFLA_GTP_CREATE_SOCKETS attribute, then GTP module takes care of creating UDP sockets by itself. Sockets are created with the commonly known UDP ports used for GTP protocol (GTP0_PORT and GTP1U_PORT). In this case we don't have to provide encap_destroy because no extra deinitialization is needed, everything is covered by udp_tunnel_sock_release. Note: GTP instance created with only this change applied, does not handle GTP Echo Requests. This is implemented in the following patch.

2022-03-10net: openvswitch: fix uAPI incompatibility with existing user spaceIlya Maximets
Few years ago OVS user space made a strange choice in the commit [1] to define types only valid for the user space inside the copy of a kernel uAPI header. '#ifndef __KERNEL__' and another attribute was added later. This leads to the inevitable clash between user space and kernel types when the kernel uAPI is extended. The issue was unveiled with the addition of a new type for IPv6 extension header in kernel uAPI. When kernel provides the OVS_KEY_ATTR_IPV6_EXTHDRS attribute to the older user space application, application tries to parse it as OVS_KEY_ATTR_PACKET_TYPE and discards the whole netlink message as malformed. Since OVS_KEY_ATTR_IPV6_EXTHDRS is supplied along with every IPv6 packet that goes to the user space, IPv6 support is fully broken. Fixing that by bringing these user space attributes to the kernel uAPI to avoid the clash. Strictly speaking this is not the problem of the kernel uAPI, but changing it is the only way to avoid breakage of the older user space applications at this point. These 2 types are explicitly rejected now since they should not be passed to the kernel. Additionally, OVS_KEY_ATTR_TUNNEL_INFO moved out from the '#ifdef __KERNEL__' as there is no good reason to hide it from the userspace. And it's also explicitly rejected now, because it's for in-kernel use only. Comments with warnings were added to avoid the problem coming back. (1 << type) converted to (1ULL << type) to avoid integer overflow on OVS_KEY_ATTR_IPV6_EXTHDRS, since it equals 32 now.

2022-03-10bpf: Remove BPF_SKB_DELIVERY_TIME_NONE and rename s/delivery_time_/tstamp_/Martin KaFai Lau
This patch is to simplify the uapi bpf.h regarding to the tstamp type and use a similar way as the kernel to describe the value stored in __sk_buff->tstamp. My earlier thought was to avoid describing the semantic and clock base for the rcv timestamp until there is more clarity on the use case, so the __sk_buff->delivery_time_type naming instead of __sk_buff->tstamp_type. With some thoughts, it can reuse the UNSPEC naming. This patch first removes BPF_SKB_DELIVERY_TIME_NONE and also rename BPF_SKB_DELIVERY_TIME_UNSPEC to BPF_SKB_TSTAMP_UNSPEC and BPF_SKB_DELIVERY_TIME_MONO to BPF_SKB_TSTAMP_DELIVERY_MONO. The semantic of BPF_SKB_TSTAMP_DELIVERY_MONO is the same: __sk_buff->tstamp has delivery time in mono clock base. BPF_SKB_TSTAMP_UNSPEC means __sk_buff->tstamp has the (rcv) tstamp at ingress and the delivery time at egress. At egress, the clock base could be found from skb->sk->sk_clockid. __sk_buff->tstamp == 0 naturally means NONE, so NONE is not needed. With BPF_SKB_TSTAMP_UNSPEC for the rcv tstamp at ingress, the __sk_buff->delivery_time_type is also renamed to __sk_buff->tstamp_type which was also suggested in the earlier discussion: https://lore.kernel.org/bpf/b181acbe-caf8-502d-4b7b-7d96b9fc5d55@iogearbox.net/ The above will then make __sk_buff->tstamp and __sk_buff->tstamp_type the same as its kernel skb->tstamp and skb->mono_delivery_time counter part. The internal kernel function bpf_skb_convert_dtime_type_read() is then renamed to bpf_skb_convert_tstamp_type_read() and it can be simplified with the BPF_SKB_DELIVERY_TIME_NONE gone. A BPF_ALU32_IMM(BPF_AND) insn is also saved by using BPF_JMP32_IMM(BPF_JSET). The bpf helper bpf_skb_set_delivery_time() is also renamed to bpf_skb_set_tstamp(). The arg name is changed from dtime to tstamp also. It only allows setting tstamp 0 for BPF_SKB_TSTAMP_UNSPEC and it could be relaxed later if there is use case to change mono delivery time to non mono. prog->delivery_time_access is also renamed to prog->tstamp_type_access.

2022-03-10io_uring: allow submissions to continue on errorJens Axboe
By default, io_uring will stop submitting a batch of requests if we run into an error submitting a request. This isn't strictly necessary, as the error result is passed out-of-band via a CQE anyway. And it can be a bit confusing for some applications. Provide a way to setup a ring that will continue submitting on error, when the error CQE has been posted. There's still one case that will break out of submission. If we fail allocating a request, then we'll still return -ENOMEM. We could in theory post a CQE for that condition too even if we never got a request. Leave that for a potential followup.

2022-03-10io_uring: add support for IORING_OP_MSG_RING commandJens Axboe
This adds support for IORING_OP_MSG_RING, which allows an SQE to signal another ring. That allows either waking up someone waiting on the ring, or even passing a 64-bit value via the user_data field in the CQE. sqe->fd must contain the fd of a ring that should receive the CQE. sqe->off will be propagated to the cqe->user_data on the target ring, and sqe->len will be propagated to cqe->res. The results CQE will have IORING_CQE_F_MSG set in its flags, to indicate that this CQE was generated from a messaging request rather than a SQE issued locally on that ring. This effectively allows passing a 64-bit and a 32-bit quantify between the two rings. This request type has the following request specific error cases: - -EBADFD. Set if the sqe->fd doesn't point to a file descriptor that is of the io_uring type. - -EOVERFLOW. Set if we were not able to deliver a request to the target ring.
