* dtrace: Remove bogus Makefile.incJohn Baldwin14 days2-25/+0
| | | | | | | | | | | | | | | This was added in the initial import of dtrace and overrides the normal load/unload targets with a custom target that loads a hardcoded set of modules. Over time, the set of modules has not been updated and is now incomplete. It's also not really useful compared to the default implementation of these targets used for loading or unloading an individual module being actively developed. This functionality is also available via dtraceall.ko which is how users commonly load the full suite of dtrace modules.

* ice: Add a failure injection facilityKevin Bowling2026-09-171-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add compile-time optional, non-sleeping fail points around every VF creation resource boundary, before VF VSI reconstruction, and in the GET_STATS validation path. Provide an ICE-wide wrapper and device selector so other driver subsystems can add scoped points without duplicating the failpoint plumbing. Keep the current SR-IOV points and VF selector in an iov child namespace. Compile the facility only with options DRIVER_FAILPOINTS. This shared option avoids a separate kernel option for every driver that provides test-only injection hooks. Ordinary kernels contain no ICE failpoint objects or sysctl nodes. Require an exact PF device name and optionally a VF index before any point can fire. This prevents a stale test setting from affecting another PF. The hooks exposed two reset-lifetime defects while validating the existing SR-IOV review series. A PF reset could discard a firmware VSI before teardown, and a rebuilt sibling could leave stale switch-filter state after IOV destroy. Tested on an E810-XXV with INVARIANTS and WITNESS. All twelve creation checkpoints rolled back and permitted immediate resource reuse. Forced reconstruction and malformed GET_STATS failures also preserved sibling operation and reply cardinality.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Hyper-V does not expose the normal Intel PF/VF mailbox. Import the Hyper-V operation overrides from DPDK and complete its reset callback with the configuration-space mechanism submitted by Microsoft. Route ixv operations through the operation table, use mailbox API 1.0, and limit this environment to one queue pair. Claim the 82599, X540, X550, X550EM-X, and X550EM-A Hyper-V device IDs listed by DPDK. Select the same path for the E610 Hyper-V subdevice identity defined there. For E610/Linkville, read the emulated VFLINKS-format status from PCI configuration space at offset 0x209. Older families retain the MMIO VFLINKS path. Treat receive-mode changes as host-owned no-ops and do not retry VLAN operations that Hyper-V permanently rejects. Limit the Hyper-V 82599 MTU to 1504 because its VF does not implement the X540 RLPML field. Use mailbox reset indications only to refresh cached Hyper-V link state. Hyper-V does not provide the mailbox handshake required to treat that indication as a request for an iflib reinitialization. Tested on 82599 and E610 (with a followup commit) with Windows Server 2025 Hyper-V.

| | | | | | | | | | | | | | | The driver only exposed a CAM SIM. Userland had no way to reach the device for anything that is not a SCSI command, so reading a descriptor or an attribute was impossible. Add /dev/ufshci%d as a root only node and the ioctl ABI header for it. The node answers no ioctl yet.

* gzoned: Introduce Zoned Storage emulatorvoidanix2026-09-032-1/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | gzoned(8) is a new GEOM class that exposes a host-managed zoned device (similar to ZAC/ZBC drives) on top of regular, non-zoned providers. The created medium is sliced into equally sized zones, by default sequential-write-required. Such zones can be turned into conventional zones if desired. The zoned drive's state and configuration is persistent through metadata at the tail of the backing provider, meaning the zoned device gets recreated at the provider retaste. Zone state changes only mark the table dirty with BIO_FLUSH committing it, mirroring drives whose zone state is volatile until a cache flush. The new class tries to emulate real zoned drives by incorporating per-zone write pointers and support for BIO_ZONE management commands. Fault emulation through zone conditions (RWP recommended, offline, R/O), URSWRZ bit toggling and concurrent open zone limits are additional features useful for testing. While at it, fix zonectl's report of write pointer LBAs for zones that should have none, remove its forced debug flags and allow the geom(8) shared subroutines to detect host-managed drives. ATF-sh tests for gzoned(8) and zonectl(8) (dogfooded by gzoned(8)) are included, featuring helpers (see zoned_subr.sh) for testing zoned storage support in other components or GEOM classes.

* linux: implement pkey_alloc, pkey_free and pkey_mprotectDevin Teske2026-08-162-2/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bridge the Linux memory protection key syscalls to FreeBSD's native MPK support instead of returning ENOSYS. Modern Linux software probes these at startup: Chromium-based browsers (found via www/linux-brave) use protection keys for V8's heap and JIT sandboxing, and glibc >= 2.27 exposes the full API. pkey_alloc() allocates from a per-process bitmap kept in the process emuldata (key 0 implicitly allocated, matching Linux's mm_pkey_allocation_map; ENOSPC once keys 1..15 are exhausted or when PKU is absent, as Linux returns on such hardware) and applies the requested initial access rights to the calling thread's PKRU, located in the XSAVE area via xsave_area_offset(). pkey_free() is bookkeeping only: as on Linux, freeing neither untags pages nor updates PKRU. pkey_mprotect() performs the protection change and tags the range through amd64_pkru_update(), factored out of sysarch(2)'s AMD64_SET_PKRU/AMD64_CLEAR_PKRU implementation so that both share the same argument checking and map read lock synchronization with a parallel pmap_vmspace_copy() on fork; tags die with the mapping, matching Linux VMA semantics. A pkey of -1 degrades to plain mprotect. The allocation map is inherited on fork and reset on exec. At exec the Linux sysvecs initialize PKRU to 0x55555554, Linux's init_pkru default (access disabled for keys 1..15), so memory tagged with a not yet allocated key is inaccessible to threads that were never granted rights -- the property V8's thread isolation relies on. Setting PKRU at exec initializes the user FPU state slightly earlier than the lazy first-use path; the state would be initialized moments later in rtld/libc startup regardless. Protection key faults already deliver SEGV_PKUERR through the existing siginfo translation. The common code carries no architecture ifdefs. Machine-dependent state lives in struct linux_pemuldata_md, embedded in the process emuldata in the manner of struct mdthread, and common code calls per-arch lifecycle hooks (linux_pemuldata_init_md/_exec_md) and pkey back ends after performing the parameter validation Linux applies regardless of hardware support. On amd64 the implementation lives in sys/amd64/linux/linux_pkru.c, compiled into linux_common and serving both the 64-bit and 32-bit Linux ABIs. Elsewhere (arm64, i386) linux_emul_md.c provides stubs returning what Linux returns on hardware without protection keys (ENOSPC from pkey_alloc; pkey_mprotect with a pkey of -1 acts as plain mprotect), so applications take their normal no-PKU fallback instead of the ENOSYS path.

* igbv: Isolate VF policy and validate its registersKevin Bowling2026-07-301-1/+1
| | | | | | | | | | | | | | | | | | | | | | | Give igb virtual functions a separate ifdi method table and move VF-specific attach, reset, queue, interrupt, and diagnostic policy to if_igbv.c. Keep shared descriptor-ring mechanisms in if_em.c. Derive VF identity from IFLIB_IS_VF and assert that hardware identification agrees. Under INVARIANTS, validate normal VF CSR accesses against the sparse 82576 and I350 VF register maps. Stop shared setup from accessing PF-only controls. Require MSI-X and defer VF sysctls until attach succeeds so failed attachment cannot leave handlers pointing at freed driver state. Advertise only VF capabilities, run adaptive moderation without the PF receive-buffer guard, enable SRRCTL.DROP_EN, and provide a VF-safe diagnostic register view. The moved implementation is the existing FreeBSD code. Register model was cross-checked against the Intel datasheets and other Intel drivers. Sponsored by: BBOX.io
* igb: Add SR-IOV PF support for 82576 and I350Kevin Bowling2026-07-301-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | Add the PCI IOV schema and PF control plane for up to seven VFs with one hardware queue per pool. Implement VF mailbox handling, MAC and VLAN assignment, multicast filtering, promiscuity policy, anti-spoofing, malicious-driver recovery, reset replay, and queue lifecycle management. The basic SR-IOV and VMDq PF implementation follows DPDK Intel e1000 code, including PF pool selection, one queue per pool, mailbox dispatch, and VF enablement. Intel FreeBSD igb-2.5.31 supplies the older driver baseline. Linux igb and the Intel SDMs clear up lifecycle, isolation, reset, and family-specific details absent from DPDK. Enabling IOV requires the PF to attach with one TX and RX queue. Systems whose defaults select RSS queues must set the documented iflib queue override tunables before attach. Only 82576 and I350 support SR-IOV in silicon. The series has been extensively tested on I350, including thowing boundaries at the PCI BAR that shipping drivers will never. Still, think carefully before reaching for this in critical environments. Relnotes: yes Sponsored by: BBOX.io
* igbv: Split 82576 and I350 VF registration off igbKevin Bowling2026-07-301-1/+2
| | | | | | | | | | | | | | | | | | | | | Register the 82576 and I350 VF PCI IDs under a separate igbv driver while continuing to share the igb datapath implementation. Follow the ixv driver split and give the VF context IFLIB_IS_VF so iflib does not apply the PF SR-IOV detach guard to a child VF. Program VTIVAR_MISC in the VF low byte so mailbox and reset notifications reach the VF admin vector. The split will become increasingly obvious as bug fixes land, trying to bias everything with if (sc->vf_ifp) everywhere is error prone in two directions. This breaks existing naming/configurations and cannot be MFCed as-is. I have no plans of adapting it to prior branches at the moment but it may be possible. Relnotes: yes Sponsored by: BBOX.io

* LinuxKPI: page pool updates and add to the buildBjoern A. Zeeb2026-07-241-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Split implementation out from the header files. This "page pool" is the very minimalistic version we need in order to support packets on mt76. We allocate the page pool in order to have the meta data available of which we only make limited use. This implementation does no pooling, it does no page fragments for now, it always hands out a full page and frees it upon return. It is written in a way that it can be in the tree before the 'struct page' work it depends on has landed in order to reduce friction for people who want to try mt7921 (or others later) upfront. We use the same #ifdef as in the struct page work for that reason so one knob will turn everything on or off. Once the struct page work has landed and settled we can start filling this with more complexity. In the unlikely event that in the mean time any other consumer would start showing up they will have to be aware that the current code as-is essentially is a NOP without the 'struct page' work. A WARN_ONCE() will notify them. Sponsored by: The FreeBSD Foundation MFC after: 3 days
* aq(4): add Atlantic 2 (AQC113) device supportNick Price2026-07-191-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for the Marvell Atlantic 2 (AQC113/114/115/116) controllers, a new chip generation that is not register-compatible with the Atlantic 1 parts aq(4) supports today. Adapted from the OpenBSD/NetBSD if_aq driver. Register and device definitions (aq2_hw.h): the firmware handshake (MIF_BOOT / MCP_HOST_REQ_INT / MIF_HOST_FINISHED), the 0x12000/0x13000 firmware interface windows, and the action-resolver table (ART) that replaces Atlantic 1's discrete RX filters, plus the Atlantic 2 PCI device ids and the aq_is_atlantic2() helper. Reserve a chip-feature bit (AQ_HW_CHIP_ATLANTIC2) and add the aq_hw fields the firmware fills at boot (ART base index, statistics interface version A0/B0). The per-VLAN-filter resolver-tag field comes from the Linux driver; the BSD sources never write it. Firmware operations (aq_fwa2.c): Atlantic 2 talks to the management CPU through the 0x12000/0x13000 register windows plus the boot handshake, rather than Atlantic 1's mailbox in shared RAM. Implement that as a third aq_firmware_ops vtable (reset, set_mode, get_mode, get_mac_addr, get_stats); aq_fwa2_reboot() boots the firmware, selects the A2 ops, and reads the version and ART base index, failing fast on the crash-init / boot-failed bits. fwa2_set_mode advertises full duplex only (the media model exposes no half-duplex types) and writes and acks the link options before raising ACTIVE mode, so a forced media change does not begin negotiation with a stale rate mask. enum aq_fw_link_speed gains aq_fw_10M, which Atlantic 2 supports and Atlantic 1 does not. Probe and attach: list the device ids with their media types and link speeds (all copper; AQC113* up to 10G, AQC116C to 1G), populate hw->device_id, and tag the generation with AQ_HW_CHIP_ATLANTIC2 so IS_CHIP_FEATURE() recognises it uniformly. Branch firmware bring-up and reset on the generation: aq_hw_init_ucp() and aq_hw_reset() reboot the MCP instead of the Atlantic 1 RBL/FLB reset -- without a real datapath reset every stop/init cycle reprograms the rings on a live, desynced RX DMA engine and the receive path stays dead. aq_hw_init() programs the Atlantic 2 launch-time clock ratio in place of the Atlantic 1 MRRS / TX-DMA request-limit clamp. Add an AQ_LINK_10M capability bit (Atlantic 2 links at 10M, Atlantic 1 cannot), offer 10baseT media, and map IFM_10_T to aq_fw_10M. With every supported media type now present, replace the per-speed switch statements in aq_media.c with a single {link bit, fw rate, IFM_* subtype, Mbit/s} table -- one source of truth for the supported link speeds. With this an Atlantic 2 card probes, brings up its firmware, reads its MAC, and negotiates link; the RX action-resolver datapath comes next.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Wacom ExpressKey Remote (ACK-411050) is a wireless button pad with 18 programmable buttons and a touch ring, used as a companion device with Wacom tablets. It communicates via a USB wireless receiver (0x056a:0x0331) using a vendor-specific HID report (ID 0x11). This driver exposes the device via evdev: - 18 buttons: BTN_0–BTN_Z, BTN_BASE, BTN_BASE2 - Touch ring position via ABS_WHEEL (0–71; reports 0 on release) - Pad activity marker via ABS_MISC (set to 15/PAD_DEVICE_ID when any input is active, 0 when idle that matches Linux wacom driver convention) - Remote serial number via MSC_SERIAL (for userland per-remote identification) Battery level, charging state, and touch ring mode (3 LEDs, values 0–2) are exposed as per-device sysctls (dev.hidwacom.0.battery, .charging, .ring_mode) rather than overloading evdev misc codes. The ring mode sysctl is preserved across device idle periods. Protocol was decoded from USB traffic analysis and cross-referenced against the Linux wacom_remote_irq() implementation in drivers/hid/wacom_wac.c.
