This allows a tracer to control the ABI of the tracee, as on arm64. Signed-off-by: Samuel Holland <samuel.holland@sifive.com> Link: https://lore.kernel.org/r/20241016202814.4061541-7-samuel.holland@sifive.com Signed-off-by: Palmer Dabbelt <palmer@rivosinc.com>
2024-10-24riscv: Add support for userspace pointer maskingSamuel Holland
RISC-V supports pointer masking with a variable number of tag bits (which is called "PMLEN" in the specification) and which is configured at the next higher privilege level. Wire up the PR_SET_TAGGED_ADDR_CTRL and PR_GET_TAGGED_ADDR_CTRL prctls so userspace can request a lower bound on the number of tag bits and determine the actual number of tag bits. As with arm64's PR_TAGGED_ADDR_ENABLE, the pointer masking configuration is thread-scoped, inherited on clone() and fork() and cleared on execve().

2024-10-24pidfd: add ioctl to retrieve pid infoLuca Boccassi
A common pattern when using pid fds is having to get information about the process, which currently requires /proc being mounted, resolving the fd to a pid, and then do manual string parsing of /proc/N/status and friends. This needs to be reimplemented over and over in all userspace projects (e.g.: I have reimplemented resolving in systemd, dbus, dbus-daemon, polkit so far), and requires additional care in checking that the fd is still valid after having parsed the data, to avoid races. Having a programmatic API that can be used directly removes all these requirements, including having /proc mounted. As discussed at LPC24, add an ioctl with an extensible struct so that more parameters can be added later if needed. Start with returning pid/tgid/ppid and creds unconditionally, and cgroupid optionally.

2024-10-23wifi: cfg80211: add option for vif allowed radiosFelix Fietkau
This allows users to prevent a vif from affecting radios other than the configured ones. This can be useful in cases where e.g. an AP is running on one radio, and triggering a scan on another radio should not disturb it. Changing the allowed radios list for a vif is supported, but only while it is down. While it is possible to achieve the same by always explicitly specifying a frequency list for scan requests and ensuring that the wrong channel/band is never accidentally set on an unrelated interface, this change makes multi-radio wiphy setups a lot easier to deal with for CLI users. By itself, this patch only enforces the radio mask for scanning requests and remain-on-channel. Follow-up changes build on this to limit configured frequencies.

2024-10-16fanotify: allow reporting errors on failure to open fdAmir Goldstein
When working in "fd mode", fanotify_read() needs to open an fd from a dentry to report event->fd to userspace. Opening an fd from dentry can fail for several reasons. For example, when tasks are gone and we try to open their /proc files or we try to open a WRONLY file like in sysfs or when trying to open a file that was deleted on the remote network server. Add a new flag FAN_REPORT_FD_ERROR for fanotify_init(). For a group with FAN_REPORT_FD_ERROR, we will send the event with the error instead of the open fd, otherwise userspace may not get the error at all. For an overflow event, we report -EBADF to avoid confusing FAN_NOFD with -EPERM. Similarly for pidfd open errors we report either -ESRCH or the open error instead of FAN_NOPIDFD and FAN_EPIDFD. In any case, userspace will not know which file failed to open, so add a debug print for further investigation.

2024-10-16usb: gadget: uvc: configfs: Add frame-based frame format supportAkash Kumar
Add support for frame-based frame format, which can be used to support multiple formats like H264 or H265, in addition to MJPEG and YUV frames. The frame-based format is set to H264 by default, but it can be updated to other formats by modifying the GUID through the guid configfs attribute. Different structures are used for all three formats, as H264 has a different structure compared to MJPEG and uncompressed formats. These structures will be passed to the frame make function based on the active format, using a common frame structure with additional parameters needed only for frame-based formats. These parameters are handled at runtime in the UVC driver.

2024-10-10thermal: core: Add user thresholds supportDaniel Lezcano
The user thresholds mechanism is a way to have the userspace to tell the thermal framework to send a notification when a temperature limit is crossed. There is no id, no hysteresis, just the temperature and the direction of the limit crossing. That means we can be notified when a threshold is crossed the way up only, or the way down only or both ways. That allows to create hysteresis values if it is needed. A threshold can be added, deleted or flushed. The latter means all thresholds belonging to a thermal zone will be deleted. When a threshold is added: - if the same threshold (temperature and direction) exists, an error is returned - if a threshold is specified with the same temperature but a different direction, the specified direction is added - if there is no threshold with the same temperature then it is created When a threshold is deleted: - if the same threshold (temperature and direction) exists, it is deleted - if a threshold is specified with the same temperature but a different direction, the specified direction is removed - if there is no threshold with the same temperature, then an error is returned When the threshold are flushed: - All thresholds related to a thermal zone are deleted When a threshold is crossed: - the userspace does not need to know which threshold(s) have been crossed, it will be notified with the current temperature and the previous temperature - if multiple thresholds have been crossed between two updates only one notification will be send to the userspace, it is pointless to send a notification per thresholds crossed as the userspace can handle that easily when it has the temperature delta information Signed-off-by: Daniel Lezcano <daniel.lezcano@linaro.org> Link: https://patch.msgid.link/20240923100005.2532430-2-daniel.lezcano@linaro.org [ rjw: Subject edit, use BIT(0) and BIT(1) in symbol definitions ] Signed-off-by: Rafael J.

2024-10-09ptp: Add support for the AMZNC10C 'vmclock' deviceDavid Woodhouse
The vmclock device addresses the problem of live migration with precision clocks. The tolerances of a hardware counter (e.g. TSC) are typically around ±50PPM. A guest will use NTP/PTP/PPS to discipline that counter against an external source of 'real' time, and track the precise frequency of the counter as it changes with environmental conditions. When a guest is live migrated, anything it knows about the frequency of the underlying counter becomes invalid. It may move from a host where the counter running at -50PPM of its nominal frequency, to a host where it runs at +50PPM. There will also be a step change in the value of the counter, as the correctness of its absolute value at migration is limited by the accuracy of the source and destination host's time synchronization. In its simplest form, the device merely advertises a 'disruption_marker' which indicates that the guest should throw away any NTP synchronization it thinks it has, and start again. Because the shared memory region can be exposed all the way to userspace through the /dev/vmclock0 node, applications can still use time from a fast vDSO 'system call', and check the disruption marker to be sure that their timestamp is indeed truthful. The structure also allows for the precise time, as known by the host, to be exposed directly to guests so that they don't have to wait for NTP to resync from scratch. The PTP driver consumes this information if present. Like the KVM PTP clock, this PTP driver can convert TSC-based cross timestamps into KVM clock values. Unlike the KVM PTP clock, it does so only when such is actually helpful. The values and fields are based on the nascent virtio-rtc specification, and the intent is that a version (hopefully precisely this version) of this structure will be included as an optional part of that spec. In the meantime, this driver supports the simple ACPI form of the device which is being shipped in certain commercial hypervisors (and submitted for inclusion in QEMU).

2024-10-08drm/xe/ptl: L3bank mask is not available on the media GTShekhar Chauhan
On PTL platforms with media version 30.00, the fuse registers for reporting L3 bank availability to the GT just read out as ~0 and do not provide proper values. Xe does not use the L3 bank mask for anything internally; it only passes the mask through to userspace via the GT topology query. Since we don't have any way to get the real L3 bank mask, we don't want to pass garbage to userspace. Passing a zeroed mask or a copy of the primary GT's L3 bank mask would also be inaccurate and likely to cause confusion for userspace. The best approach is to simply not include L3 in the list of masks returned by the topology query in cases where we aren't able to provide a meaningful value. This won't change the behavior for any existing platforms (where we can always obtain L3 masks successfully for all GTs), it will only prevent us from mis-reporting bad information on upcoming platform(s). There's a good chance this will become a formal workaround in the future, but for now we don't have a lineage number so "no_media_l3" is used in place of a lineage as the OOB workaround descriptor. v2: - Re-calculate query size to properly match data returned. (Gustavo) - Update kerneldoc to clarify that the L3bank mask may not be included in the query results if the hardware doesn't make it available.

2024-10-07netkit: Add option for scrubbing skb meta dataDaniel Borkmann
Jordan reported that when running Cilium with netkit in per-endpoint-routes mode, network policy misclassifies traffic. In this direct routing mode of Cilium which is used in case of GKE/EKS/AKS, the Pod's BPF program to enforce policy sits on the netkit primary device's egress side. The issue here is that in case of netkit's netkit_prep_forward(), it will clear meta data such as skb->mark and skb->priority before executing the BPF program. Thus, identity data stored in there from earlier BPF programs (e.g. from tcx ingress on the physical device) gets cleared instead of being made available for the primary's program to process. While for traffic egressing the Pod via the peer device this might be desired, this is different for the primary one where compared to tcx egress on the host veth this information would be available. To address this, add a new parameter for the device orchestration to allow control of skb->mark and skb->priority scrubbing, to make the two accessible from BPF (and eventually leave it up to the program to scrub). By default, the current behavior is retained. For netkit peer this also enables the use case where applications could cooperate/signal intent to the BPF program. Note that struct netkit has a 4 byte hole between policy and bundle which is used here, in other words, struct netkit's first cacheline content used in fast-path does not get moved around.
