2018-11-30net: dsa: Fix tagging attribute locationFlorian Fainelli1-1/+1
While introducing the DSA tagging protocol attribute, it was added to the DSA slave network devices, but those actually see untagged traffic (that is their whole purpose). Correct this mistake by putting the tagging sysfs attribute under the DSA master network device where this is the information that we need. While at it, also correct the sysfs documentation mistake that missed the "dsa/" directory component of the attribute.

2018-09-28usb: core: added uevent for over-currentJon Flatley1-1/+8
After commit 1cbd53c8cd85 ("usb: core: introduce per-port over-current counters") usb ports expose a sysfs value 'over_current_count' to user space. This value on its own is not very useful as it requires manual polling. As a solution, fire a udev event from the usb hub device that specifies the values 'OVER_CURRENT_PORT' and 'OVER_CURRENT_COUNT' that indicate the path of the usb port where the over-current event occurred and the value of 'over_current_count' in sysfs. Additionally, call sysfs_notify() so the sysfs value supports poll(). Signed-off-by: Jon Flatley <jflat@chromium.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2018-09-24usb: gadget: uvc: configfs: Add bFrameIndex attributesJoel Pepper1-0/+8
- Add bFrameIndex as a UVCG_FRAME_ATTR_RO for each frame size. - Automatically assign ascending bFrameIndex to each frame in a format. Before all "bFrameindex" attributes were set to "1" with no way to configure the gadget otherwise. This resulted in the host always negotiating for bFrameIndex 1 (i.e. the first frame size of the gadget). After the negotiation the host driver will set the user or application selected frame size, while the gadget is actually set to the first frame size. Now, when the containing format is linked into the streaming header, iterate over all child frame descriptors and assign ascending indices. The automatically assigned indices can be read from the new read only bFrameIndex configfs attribute in each frame descriptor item.

2018-09-24usb: gadget: uvc: configfs: Add bFormatIndex attributesLaurent Pinchart1-0/+8
The UVC format description are numbered using the descriptor's bFormatIndex field. The index is used in UVC requests, and is thus needed to handle requests in userspace. Make it dynamically discoverable by exposing it in a bFormatIndex configfs attribute of the uncompressed and mjpeg format config items. The bFormatIndex value exposed through the attribute is stored in the config item private data. However, that value is never set: the driver instead computes the bFormatIndex value when linking the stream class header in the configfs hierarchy and stores it directly in the class descriptors in a separate structure. In order to expose the value through the configfs attribute, store it in the config item private data as well. This results in a small code simplification.

2018-09-14xen/balloon: add runtime control for scrubbing ballooned out pagesMarek Marczykowski-Górecki1-0/+9
Scrubbing pages on initial balloon down can take some time, especially in nested virtualization case (nested EPT is slow). When HVM/PVH guest is started with memory= significantly lower than maxmem=, all the extra pages will be scrubbed before returning to Xen. But since most of them weren't used at all at that point, Xen needs to populate them first (from populate-on-demand pool). In nested virt case (Xen inside KVM) this slows down the guest boot by 15-30s with just 1.5GB needed to be returned to Xen. Add runtime parameter to enable/disable it, to allow initially disabling scrubbing, then enable it back during boot (for example in initramfs). Such usage relies on assumption that a) most pages ballooned out during initial boot weren't used at all, and b) even if they were, very few secrets are in the guest at that time (before any serious userspace kicks in). Convert CONFIG_XEN_SCRUB_PAGES to CONFIG_XEN_SCRUB_PAGES_DEFAULT (also enabled by default), controlling default value for the new runtime switch.

Persistent grants are allocated until a threshold per ring is being reached. Those grants won't be freed until the ring is being destroyed meaning there will be resources kept busy which might no longer be used. Instead of freeing only persistent grants until the threshold is reached add a timestamp and remove all persistent grants not having been in use for a minute.

git://git.infradead.org/linux-platform-drivers-x86 Pull x86 platform driver updates from Andy Shevchenko: - The driver for Silead touchscreen configurations has been renamed from silead_dmi to touchscreen_dmi since it starts supporting other touchscreens which require some DMI quirks It also gets expanded to cover cases for Chuwi Vi10, ONDA V891W, Connect Tablet 9, Onda V820w, and Cube KNote i1101 tablets. - Another bunch of changes is related to Mellanox platform code to allow user space to communicate with Mellanox for system control and monitoring purposes. The driver notifies user on hotplug device signal receiving. - ASUS WMI drivers recognize lid flip action on UX360, and correctly toggles airplane mode LED. In addition the keyboard backlight toggle gets support. - ThinkPad ACPI driver enables support for calculator key (on at least P52). It also has been fixed to support three characters model designators, which are used for modern laptops. Earlier the battery, marked as BAT1, on ThinkPad laptops has not been configured properly, which is fixed. On the opposite the multi-battery configurations now probed correctly. - Dell SMBIOS driver starts working on some Dell servers which do not support token interface. The regression with backlight detection has also been fixed. In order to support dock mode on some laptops, Intel virtual button driver has been fixed. The last but not least is the fix to Intel HID driver due to changes in Dell systems that prevented to use power button. * tag 'platform-drivers-x86-v4.19-1' of git://git.infradead.org/linux-platform-drivers-x86: (47 commits) platform/x86: acer-wmi: Silence "unsupported" message a bit platform/x86: intel_punit_ipc: fix build errors platform/x86: ideapad: Add Y520-15IKBM and Y720-15IKBM to no_hw_rfkill platform/x86: asus-nb-wmi: Add keymap entry for lid flip action on UX360 platform/x86: acer-wmi: refactor function has_cap platform/x86: thinkpad_acpi: Fix multi-battery bug platform/x86: thinkpad_acpi: extend battery quirk coverage platform/x86: touchscreen_dmi: Add info for the Cube KNote i1101 tablet platform/x86: mlx-platform: Fix copy-paste error in mlxplat_init() platform/x86: mlx-platform: Remove unused define platform/x86: mlx-platform: Change mlxreg-io configuration for MSN274x systems Documentation/ABI: Add new attribute for mlxreg-io sysfs interfaces platform/x86: mlx-platform: Allow mlxreg-io driver activation for more systems platform/x86: mlx-platform: Add ASIC hotplug device configuration platform/mellanox: mlxreg-hotplug: Add hotplug hwmon uevent notification platform/mellanox: mlxreg-hotplug: Improve mechanism of ASIC health discovery platform/x86: mlx-platform: Add mlxreg-fan platform driver activation platform/x86: dell-laptop: Fix backlight detection platform/x86: toshiba_acpi: Fix defined but not used build warnings platform/x86: thinkpad_acpi: Support battery quirk ...

git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs Pull f2fs updates from Jaegeuk Kim: "In this round, we've tuned f2fs to improve general performance by serializing block allocation and enhancing discard flows like fstrim which avoids user IO contention. And we've added fsync_mode=nobarrier which gives an option to user where it skips issuing cache_flush commands to underlying flash storage. And there are many bug fixes related to fuzzed images, revoked atomic writes, quota ops, and minor direct IO. Enhancements: - add fsync_mode=nobarrier which bypasses cache_flush command - enhance the discarding flow which avoids user IOs and issues in LBA order - readahead some encrypted blocks during GC - enable in-memory inode checksum to verify the blocks if F2FS_CHECK_FS is set - enhance nat_bits behavior - set -o discard by default - set REQ_RAHEAD to bio in ->readpages Bug fixes: - fix a corner case to corrupt atomic_writes revoking flow - revisit i_gc_rwsem to fix race conditions - fix some dio behaviors captured by xfstests - correct handling errors given by quota-related failures - add many sanity check flows to avoid fuzz test failures - add more error number propagation to their callers - fix several corner cases to continue fault injection w/ shutdown loop" * tag 'f2fs-for-4.19' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs: (89 commits) f2fs: readahead encrypted block during GC f2fs: avoid fi->i_gc_rwsem[WRITE] lock in f2fs_gc f2fs: fix performance issue observed with multi-thread sequential read f2fs: fix to skip verifying block address for non-regular inode f2fs: rework fault injection handling to avoid a warning f2fs: support fault_type mount option f2fs: fix to return success when trimming meta area f2fs: fix use-after-free of dicard command entry f2fs: support discard submission error injection f2fs: split discard command in prior to block layer f2fs: wake up gc thread immediately when gc_urgent is set f2fs: fix incorrect range->len in f2fs_trim_fs() f2fs: refresh recent accessed nat entry in lru list f2fs: fix avoid race between truncate and background GC f2fs: avoid race between zero_range and background GC f2fs: fix to do sanity check with block address in main area v2 f2fs: fix to do sanity check with inline flags f2fs: fix to reset i_gc_failures correctly f2fs: fix invalid memory access f2fs: fix to avoid broken of dnode block list ...

Anyway, major things here are: - new FSI driver subsystem, yet-another-powerpc low-level hardware bus - gnss, finally an in-kernel GPS subsystem to try to tame all of the crazy out-of-tree drivers that have been floating around for years, combined with some really hacky userspace implementations. This is only for GNSS receivers, but you have to start somewhere, and this is great to see. Other than that, there are new slimbus drivers, new coresight drivers, new fpga drivers, and loads of DT bindings for all of these and existing drivers.
