git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing fixes from Steven Rostedt: - Fix MAINTAINERS file to point to proper mailing list for rtla and rv The mailing list pointed to linux-trace-devel instead of linux-trace-kernel. The former is for the tracing libraries and the latter is for anything in the Linux kernel tree. The wrong mailing list was used because linux-trace-kernel did not exist when rtla and rv were created. - User events: - Fix matching of dynamic events to their user events When user writes to dynamic_events file, a lookup of the registered dynamic events is made, but there were some cases that a match could be incorrectly made. - Add auto cleanup of user events Have the user events automatically get removed when the last reference (file descriptor) is closed. This was asked for to prevent leaks of user events hanging around needing admins to clean them up. - Add persistent logic (but not let user space use it yet) In some cases, having a persistent user event (one that does not get cleaned up automatically) is useful. But there's still debates about how to expose this to user space. The infrastructure is added, but the API is not. - Update the selftests Update the user event selftests to reflect the above changes" * tag 'trace-v6.4-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: tracing/user_events: Document auto-cleanup and remove dyn_event refs selftests/user_events: Adapt dyn_test to non-persist events selftests/user_events: Ensure auto cleanup works as expected tracing/user_events: Add auto cleanup and future persist flag tracing/user_events: Track refcount consistently via put/get tracing/user_events: Store register flags on events tracing/user_events: Remove user_ns walk for groups selftests/user_events: Add perf self-test for empty arguments events selftests/user_events: Clear the events after perf self-test selftests/user_events: Add ftrace self-test for empty arguments events tracing/user_events: Fix the incorrect trace record for empty arguments events tracing: Modify print_fields() for fields output order tracing/user_events: Handle matching arguments that is null from dyn_events tracing/user_events: Prevent same name but different args event tracing/rv/rtla: Update MAINTAINERS file to point to proper mailing list

Function btrfs_max_io_len() is to get the length to the stripe boundary. It calculates the full stripe start offset (inside the chunk) by the following code: *full_stripe_start = rounddown(*stripe_nr, nr_data_stripes(map)) << BTRFS_STRIPE_LEN_SHIFT; The calculation itself is fine, but the value returned by rounddown() is dependent on both @stripe_nr (which is u32) and nr_data_stripes() (which returned int). Thus the result is also u32, then we do the left shift, which can overflow u32. If such overflow happens, @full_stripe_start will be a value way smaller than @offset, causing later "full_stripe_len - (offset - *full_stripe_start)" to underflow, thus make later length calculation to have no stripe boundary limit, resulting a write bio to exceed stripe boundary. There are some other locations like this, with a u32 @stripe_nr got left shift, which can lead to a similar overflow. [FIX] Fix all @stripe_nr with left shift with a type cast to u64 before the left shift. Those involved @stripe_nr or similar variables are recording the stripe number inside the chunk, which is small enough to be contained by u32, but their offset inside the chunk can not fit into u32. Thus for those specific left shifts, a type cast to u64 is necessary so this patch does not touch them and the code will be cleaned up in the future to keep the fix minimal.

2023-06-18PCI: hv: Add a per-bus mutex state_lockDexuan Cui1-3/+26
In the case of fast device addition/removal, it's possible that hv_eject_device_work() can start to run before create_root_hv_pci_bus() starts to run; as a result, the pci_get_domain_bus_and_slot() in hv_eject_device_work() can return a 'pdev' of NULL, and hv_eject_device_work() can remove the 'hpdev', and immediately send a message PCI_EJECTION_COMPLETE to the host, and the host immediately unassigns the PCI device from the guest; meanwhile, create_root_hv_pci_bus() and the PCI device driver can be probing the dead PCI device and reporting timeout errors. Fix the issue by adding a per-bus mutex 'state_lock' and grabbing the mutex before powering on the PCI bus in hv_pci_enter_d0(): when hv_eject_device_work() starts to run, it's able to find the 'pdev' and call pci_stop_and_remove_bus_device(pdev): if the PCI device driver has loaded, the PCI device driver's probe() function is already called in create_root_hv_pci_bus() -> pci_bus_add_devices(), and now hv_eject_device_work() -> pci_stop_and_remove_bus_device() is able to call the PCI device driver's remove() function and remove the device reliably; if the PCI device driver hasn't loaded yet, the function call hv_eject_device_work() -> pci_stop_and_remove_bus_device() is able to remove the PCI device reliably and the PCI device driver's probe() function won't be called; if the PCI device driver's probe() is already running (e.g., systemd-udev is loading the PCI device driver), it must be holding the per-device lock, and after the probe() finishes and releases the lock, hv_eject_device_work() -> pci_stop_and_remove_bus_device() is able to proceed to remove the device reliably.

2023-06-18Revert "PCI: hv: Fix a timing issue which causes kdump to fail occasionally"Dexuan Cui1-37/+34
This reverts commit d6af2ed29c7c1c311b96dac989dcb991e90ee195. The statement "the hv_pci_bus_exit() call releases structures of all its child devices" in commit d6af2ed29c7c is not true: in the path hv_pci_probe() -> hv_pci_enter_d0() -> hv_pci_bus_exit(hdev, true): the parameter "keep_devs" is true, so hv_pci_bus_exit() does *not* release the child "struct hv_pci_dev *hpdev" that is created earlier in pci_devices_present_work() -> new_pcichild_device(). The commit d6af2ed29c7c was originally made in July 2020 for RHEL 7.7, where the old version of hv_pci_bus_exit() was used; when the commit was rebased and merged into the upstream, people didn't notice that it's not really necessary. The commit itself doesn't cause any issue, but it makes hv_pci_probe() more complicated. Revert it to facilitate some upcoming changes to hv_pci_probe().

2023-06-18PCI: hv: Fix a race condition in hv_irq_unmask() that can cause panicDexuan Cui1-6/+5
When the host tries to remove a PCI device, the host first sends a PCI_EJECT message to the guest, and the guest is supposed to gracefully remove the PCI device and send a PCI_EJECTION_COMPLETE message to the host; the host then sends a VMBus message CHANNELMSG_RESCIND_CHANNELOFFER to the guest (when the guest receives this message, the device is already unassigned from the guest) and the guest can do some final cleanup work; if the guest fails to respond to the PCI_EJECT message within one minute, the host sends the VMBus message CHANNELMSG_RESCIND_CHANNELOFFER and removes the PCI device forcibly. In the case of fast device addition/removal, it's possible that the PCI device driver is still configuring MSI-X interrupts when the guest receives the PCI_EJECT message; the channel callback calls hv_pci_eject_device(), which sets hpdev->state to hv_pcichild_ejecting, and schedules a work hv_eject_device_work(); if the PCI device driver is calling pci_alloc_irq_vectors() -> ... -> hv_compose_msi_msg(), we can break the while loop in hv_compose_msi_msg() due to the updated hpdev->state, and leave data->chip_data with its default value of NULL; later, when the PCI device driver calls request_irq() -> ... -> hv_irq_unmask(), the guest crashes in hv_arch_irq_unmask() due to data->chip_data being NULL. Fix the issue by not testing hpdev->state in the while loop: when the guest receives PCI_EJECT, the device is still assigned to the guest, and the guest has one minute to finish the device removal gracefully. We don't really need to (and we should not) test hpdev->state in the loop.

2023-06-18ata: libata-scsi: Avoid deadlock on rescan after device resumeDamien Le Moal4-4/+25
When an ATA port is resumed from sleep, the port is reset and a power management request issued to libata EH to reset the port and rescanning the device(s) attached to the port. Device rescanning is done by scheduling an ata_scsi_dev_rescan() work, which will execute scsi_rescan_device(). However, scsi_rescan_device() takes the generic device lock, which is also taken by dpm_resume() when the SCSI device is resumed as well. If a device rescan execution starts before the completion of the SCSI device resume, the rcu locking used to refresh the cached VPD pages of the device, combined with the generic device locking from scsi_rescan_device() and from dpm_resume() can cause a deadlock. Avoid this situation by changing struct ata_port scsi_rescan_task to be a delayed work instead of a simple work_struct. ata_scsi_dev_rescan() is modified to check if the SCSI device associated with the ATA device that must be rescanned is not suspended. If the SCSI device is still suspended, ata_scsi_dev_rescan() returns early and reschedule itself for execution after an arbitrary delay of 5ms.

State CPUHP_AP_HYPERV_ONLINE has been introduced to correctly sequence the initialization of hyperv_pcpu_input_arg.

2023-06-18x86/hyperv: Fix hyperv_pcpu_input_arg handling when CPUs go online/offlineMichael Kelley3-25/+26
These commits a494aef23dfc ("PCI: hv: Replace retarget_msi_interrupt_params with hyperv_pcpu_input_arg") 2c6ba4216844 ("PCI: hv: Enable PCI pass-thru devices in Confidential VMs") update the Hyper-V virtual PCI driver to use the hyperv_pcpu_input_arg because that memory will be correctly marked as decrypted or encrypted for all VM types (CoCo or normal). But problems ensue when CPUs in the VM go online or offline after virtual PCI devices have been configured. When a CPU is brought online, the hyperv_pcpu_input_arg for that CPU is initialized by hv_cpu_init() running under state CPUHP_AP_ONLINE_DYN. But this state occurs after state CPUHP_AP_IRQ_AFFINITY_ONLINE, which may call the virtual PCI driver and fault trying to use the as yet uninitialized hyperv_pcpu_input_arg. A similar problem occurs in a CoCo VM if the MMIO read and write hypercalls are used from state CPUHP_AP_IRQ_AFFINITY_ONLINE. When a CPU is taken offline, IRQs may be reassigned in state CPUHP_TEARDOWN_CPU. Again, the virtual PCI driver may fault trying to use the hyperv_pcpu_input_arg that has already been freed by a higher state. Fix the onlining problem by adding state CPUHP_AP_HYPERV_ONLINE immediately after CPUHP_AP_ONLINE_IDLE (similar to CPUHP_AP_KVM_ONLINE) and before CPUHP_AP_IRQ_AFFINITY_ONLINE. Use this new state for Hyper-V initialization so that hyperv_pcpu_input_arg is allocated early enough. Fix the offlining problem by not freeing hyperv_pcpu_input_arg when a CPU goes offline. Retain the allocated memory, and reuse it if the CPU comes back online later.

This commit adds new DEVICE_FLG with QUIRK_FLAG_DSD_RAW and Vendor Id for HEM devices which supports native DSD. Prior to this change Linux kernel was not enabling native DSD playback for HEM devices, and as a result, DSD audio was being converted to PCM "on the fly". HEM devices, when connected to the system, would only play audio in PCM format, even if the source material was in DSD format. With the addition of new VENDOR_FLG in the quircks.c file, the devices are now correctly recognized, and raw DSD data is transmitted to the device, allowing for native DSD playback.

2023-06-16ALSA: usb-audio: Fix broken resume due to UAC3 power stateTakashi Iwai1-0/+4
As reported in the bugzilla below, the PM resume of a UAC3 device may fail due to the incomplete power state change, stuck at D1. The reason is that the driver expects the full D0 power state change only at hw_params, while the normal PCM resume procedure doesn't call hw_params. For fixing the bug, we add the same power state update to D0 at the prepare callback, which is certainly called by the resume procedure. Note that, with this change, the power state change in the hw_params becomes almost redundant, since snd_usb_hw_params() doesn't touch the parameters (at least it tires so). But dropping it is still a bit risky (e.g. we have the media-driver binding), so I leave the D0 power state change in snd_usb_hw_params() as is for now.

Current release - regressions: - wifi: - cfg80211: fix double lock bug in reg_wdev_chan_valid() - iwlwifi: mvm: spin_lock_bh() to fix lockdep regression Current release - new code bugs: - handshake: remove fput() that causes use-after-free Previous releases - regressions: - sched: cls_u32: fix reference counter leak leading to overflow - sched: cls_api: fix lockup on flushing explicitly created chain Previous releases - always broken: - nf_tables: integrate pipapo into commit protocol - nf_tables: incorrect error path handling with NFT_MSG_NEWRULE, fix dangling pointer on failure - ping6: fix send to link-local addresses with VRF - sched: act_pedit: parse L3 header for L4 offset, the skb may not have the offset saved - sched: act_ct: fix promotion of offloaded unreplied tuple - sched: refuse to destroy an ingress and clsact Qdiscs if there are lockless change operations in flight - wifi: mac80211: fix handful of bugs in multi-link operation - ipvlan: fix bound dev checking for IPv6 l3s mode - eth: enetc: correct the indexes of highest and 2nd highest TCs - eth: ice: fix XDP memory leak when NIC is brought up and down Misc: - add deprecation notices for UDP-lite and DCCP - selftests: mptcp: skip tests not supported by old kernels - sctp: handle invalid error codes without calling BUG()" * tag 'net-6.4-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net: (91 commits) dccp: Print deprecation notice. udplite: Print deprecation notice. octeon_ep: Add missing check for ioremap selftests/ptp: Fix timestamp printf format for PTP_SYS_OFFSET net: ethernet: stmicro: stmmac: fix possible memory leak in __stmmac_open net: tipc: resize nlattr array to correct size sfc: fix XDP queues mode with legacy IRQ net: macsec: fix double free of percpu stats net: lapbether: only support ethernet devices MAINTAINERS: add reviewers for SMC Sockets s390/ism: Fix trying to free already-freed IRQ by repeated ism_dev_exit() net: dsa: felix: fix taprio guard band overflow at 10Mbps with jumbo frames net/sched: cls_api: Fix lockup on flushing explicitly created chain ice: Fix ice module unload net/handshake: remove fput() that causes use-after-free selftests: forwarding: hw_stats_l3: Set addrgenmode in a separate step net/sched: qdisc_destroy() old ingress and clsact Qdiscs before grafting net/sched: Refactor qdisc_graft() for ingress and clsact Qdiscs net/sched: act_ct: Fix promotion of offloaded unreplied tuple wifi: iwlwifi: mvm: spin_lock_bh() to fix lockdep regression ...

Pull rdma fixes from Jason Gunthorpe: "This is an unusually large bunch of bug fixes for the later rc cycle, rxe and mlx5 both dumped a lot of things at once. rxe continues to fix itself, and mlx5 is fixing a bunch of "queue counters" related bugs. There is one highly notable bug fix regarding the qkey. This small security check was missed in the original 2005 implementation and it allows some significant issues. Summary: - Two rtrs bug fixes for error unwind bugs - Several rxe bug fixes: * Incorrect Rx packet validation * Using memory without a refcount * Syzkaller found use before initialization * Regression fix for missing locking with the tasklet conversion from this merge window - Have bnxt report the correct link properties to userspace, this was a regression in v6.3 - Several mlx5 bug fixes: * Kernel crash triggerable by userspace for the RAW ethernet profile * Defend against steering refcounting issues created by userspace * Incorrect change of QP port affinity parameters in some LAG configurations - Fix mlx5 Q counters: * Do not over allocate Q counters to allow userspace to use the full port capacity * Kernel crash triggered by eswitch due to mis-use of Q counters * Incorrect mlx5_device for Q counters in some LAG configurations - Properly implement the IBA spec restricting privileged qkeys to root - Always an error when reading from a disassociated device's event queue - isert bug fixes: * Avoid a deadlock with the CM handler and CM ID destruction * Correct list corruption due to incorrect locking * Fix a use after free around connection tear down" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma: RDMA/rxe: Fix rxe_cq_post IB/isert: Fix incorrect release of isert connection IB/isert: Fix possible list corruption in CMA handler IB/isert: Fix dead lock in ib_isert RDMA/mlx5: Fix affinity assignment IB/uverbs: Fix to consider event queue closing also upon non-blocking mode RDMA/uverbs: Restrict usage of privileged QKEYs RDMA/cma: Always set static rate to 0 for RoCE RDMA/mlx5: Fix Q-counters query in LAG mode RDMA/mlx5: Remove vport Q-counters dependency on normal Q-counters RDMA/mlx5: Fix Q-counters per vport allocation RDMA/mlx5: Create an indirect flow table for steering anchor RDMA/mlx5: Initiate dropless RQ for RAW Ethernet functions RDMA/rxe: Fix the use-before-initialization error of resp_pkts RDMA/bnxt_re: Fix reporting active_{speed,width} attributes RDMA/rxe: Fix ref count error in check_rkey() RDMA/rxe: Fix packet length checks RDMA/rtrs: Fix rxe_dealloc_pd warning RDMA/rtrs: Fix the last iu->buf leak in err path
