2021-04-15media: v4l2-ctrls: fix reference to freed memoryHans Verkuil
When controls are used together with the Request API, then for each request a v4l2_ctrl_handler struct is allocated. This contains the controls that can be set in a request. If a control is *not* set in the request, then the value used in the most recent previous request must be used, or the current value if it is not found in any outstanding requests. The framework tried to find such a previous request and it would set the 'req' pointer in struct v4l2_ctrl_ref to the v4l2_ctrl_ref of the control in such a previous request. So far, so good. However, when that previous request was applied to the hardware, returned to userspace, and then userspace would re-init or free that request, any 'ref' pointer in still-queued requests would suddenly point to freed memory. This was not noticed before since the drivers that use this expected that each request would always have the controls set, so there was never any need to find a control in older requests. This requirement was relaxed, and now this bug surfaced. It was also made worse by changeset 2fae4d6aabc8 ("media: v4l2-ctrls: v4l2_ctrl_request_complete() should always set ref->req") which increased the chance of this happening. The use of the 'req' pointer in v4l2_ctrl_ref was very fragile, so drop this entirely. Instead add a valid_p_req bool to indicate that p_req contains a valid value for this control. And if it is false, then just use the current value of the control. Note that VIDIOC_G_EXT_CTRLS will always return -EACCES when attempting to get a control from a request until the request is completed. And in that case, all controls in the request will have the control value set (i.e. valid_p_req is true). This means that the whole 'find the most recent previous request containing a control' idea is pointless, and the code can be simplified considerably. The v4l2_g_ext_ctrls_common() function was refactored a bit to make it more understandable. It also avoids updating volatile controls in a completed request since that was already done when the request was completed.

2021-03-22media: uapi: move VP8 stateless controls out of stagingEzequiel Garcia
Until now, the VP8 V4L2 API was not exported as a public API, and only defined in a private media header (media/vp8-ctrls.h). The reason for this was a concern about the API not complete and ready to support VP8 decoding hardware accelerators. After reviewing the VP8 specification in detail, and now that the API is able to support Cedrus and Hantro G1, we can consider this ready.

In detail: - Fully serialize manager and worker creation, fixing races due to that. - Clean up some naming that had gone stale. - SQPOLL fixes. - Fix race condition around task_work rework that went into this merge window. - Implement unshare. Used for when the original task does unshare(2) or setuid/seteuid and friends, drops the original workers and forks new ones. - Drop the only remaining piece of state shuffling we had left, which was cred. Move it into issue instead, and we can drop all of that code too. - Kill f_op->flush() usage. That was such a nasty hack that we had out of necessity, we no longer need it. - Following from ->flush() removal, we can also drop various bits of ctx state related to SQPOLL and cancelations. - Fix an issue with IOPOLL retry, which originally was fallout from a filemap change (removing iov_iter_revert()), but uncovered an issue with iovec re-import too late. - Fix an issue with system suspend. - Use xchg() for fallback work, instead of cmpxchg(). - Properly destroy io-wq on exec. - Add create_io_thread() core helper, and use that in io-wq and io_uring. This allows us to remove various silly completion events related to thread setup. - A few error handling fixes. This should be the grunt of fixes necessary for the new workers, next week should be quieter. We've got a pending series from Pavel on cancelations, and how tasks and rings are indexed.

2021-03-04io_uring: destroy io-wq on execPavel Begunkov
Destroy current's io-wq backend and tctx on __io_uring_task_cancel(), aka exec(). Looks it's not strictly necessary, because it will be done at some point when the task dies and changes of creds/files/etc. are handled, but better to do that earlier to free io-wq and not potentially lock previous mm and other resources for the time being. It's safe to do because we wait for all requests of the current task to complete, so no request will use tctx afterwards. Note, that io_uring_files_cancel() may leave some requests for later reaping, so it leaves tctx intact, that's ok as the task is dying anyway.

2021-03-02KVM: x86/xen: Add support for vCPU runstate informationDavid Woodhouse
This is how Xen guests do steal time accounting. The hypervisor records the amount of time spent in each of running/runnable/blocked/offline states. In the Xen accounting, a vCPU is still in state RUNSTATE_running while in Xen for a hypercall or I/O trap, etc. Only if Xen explicitly schedules does the state become RUNSTATE_blocked. In KVM this means that even when the vCPU exits the kvm_run loop, the state remains RUNSTATE_running. The VMM can explicitly set the vCPU to RUNSTATE_blocked by using the KVM_XEN_VCPU_ATTR_TYPE_RUNSTATE_CURRENT attribute, and can also use KVM_XEN_VCPU_ATTR_TYPE_RUNSTATE_ADJUST to retrospectively add a given amount of time to the blocked state and subtract it from the running state. The state_entry_time corresponds to get_kvmclock_ns() at the time the vCPU entered the current state, and the total times of all four states should always add up to state_entry_time.

2021-03-02Merge tag 'tags/sound-sdw-kconfig-fixes' into for-linusTakashi Iwai
ALSA/ASoC/SOF/SoundWire: fix Kconfig issues In January, Intel kbuild bot and Arnd Bergmann reported multiple issues with randconfig. This patchset builds on Arnd's suggestions to a) expose ACPI and PCI devices in separate modules, while sof-acpi-dev and sof-pci-dev become helpers. This will result in minor changes required for developers/testers, i.e. modprobe snd-sof-pci will no longer result in a probe. The SOF CI was already updated to deal with this module dependency change and introduction of new modules. b) Fix SOF/SoundWire/DSP_config dependencies by moving the code required to detect SoundWire presence in ACPI tables to sound/hda.

2021-03-02ALSA: hda: move Intel SoundWire ACPI scan to dedicated modulePierre-Louis Bossart
The ACPI scan capabilities is called from the intel-dspconfig as well as the SOF/HDaudio drivers. This creates dependencies and randconfig issues when HDaudio and SOF/SoundWire are not all configured as modules. To simplify Kconfig dependencies between HDAudio, SoundWire, SOF and intel-dspconfig, move the ACPI scan helpers to a dedicated module. This follows the same idea as NHLT helpers which are already handled as a dedicated module. The only functional change is that the kernel parameter to filter links is now handled by a different module, but that was only provided for developers needing work-arounds for early BIOS releases.
