The `connected` value for wired devices was not properly initialized, it must be set to `true` upon creation, because wired devices do not generate connection events. When a raw client (the Steam Client) uses the device, the input device is destroyed. Then, when the raw client finishes, it must be recreated. But since the `connected` variable was false this never happended. Signed-off-by: Rodrigo Rivas Costa <rodrigorivascosta@gmail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

The open method of hiddev handler fails to bring the device out of autosuspend state as was promised in 0361a28d, as it actually has 2 blocks that try to start the transport (call hid_hw_open()) with both being guarded by the "open" counter, so the 2nd block is never executed as the first block increments the counter so it is never at 0 when we check it for the second block. Additionally hiddev_open() was leaving counter incremented on errors, causing the device to never be reopened properly if there was ever an error. Let's fix all of this by factoring out code that creates client structure and powers up the device into a separate function that is being called from usbhid_open() with the "existancelock" being held.

The Acer SW5-012 2-in-1 keyboard dock uses a Synaptics S91028 touchpad which is connected to an ITE 8595 USB keyboard controller chip. This keyboard has the same quirk for its rfkill / airplane mode hotkey as other keyboards with the ITE 8595 chip, it only sends a single release event when pressed and released, it never sends a press event. This commit adds this keyboards USB id to the hid-ite id-table, fixing the rfkill key not working on this keyboard.

The syzbot fuzzer found a slab-out-of-bounds bug in the HID report handler. The bug was caused by a report descriptor which included a field with size 12 bits and count 4899, for a total size of 7349 bytes. The usbhid driver uses at most a single-page 4-KB buffer for reports. In the test there wasn't any problem about overflowing the buffer, since only one byte was received from the device. Rather, the bug occurred when the HID core tried to extract the data from the report fields, which caused it to try reading data beyond the end of the allocated buffer. This patch fixes the problem by rejecting any report whose total length exceeds the HID_MAX_BUFFER_SIZE limit (minus one byte to allow for a possible report index). In theory a device could have a report longer than that, but if there was such a thing we wouldn't handle it correctly anyway.

When polling a connected /dev/hidrawX device, it is useful to get the EPOLLOUT when writing is possible. Since writing is possible as soon as the device is connected, always return it. Right now EPOLLOUT is only returned when there are also input reports are available. This works if devices start sending reports when connected, but some HID devices might need an output report first before sending any input reports. This change will allow using EPOLLOUT here as well.

Pull GPIO updates from Linus Walleij: "This is the bulk of GPIO changes for the v5.5 kernel cycle Core changes: - Expose pull up/down flags for the GPIO character device to userspace. After clear input from the RaspberryPi and Beagle communities, it has been established that prototyping, industrial automation and make communities strongly need this feature, and as we want people to use the character device, we have implemented the simple pull up/down interface for GPIO lines. This means we can specify that a (chip-specific) pull up/down resistor can be enabled, but does not offer fine-grained control such as cases where the resistance of the same pull resistor can be controlled (yet). - Introduce devm_fwnode_gpiod_get_index() and start to phase out the old symbol devm_fwnode_get_index_gpiod_from_child(). - A bit of documentation clean-up work. - Introduce a define for GPIO line directions and deploy it in all GPIO drivers in the drivers/gpio directory. - Add a special callback to populate pin ranges when cooperating with the pin control subsystem and registering ranges as part of adding a gpiolib driver and a gpio_irq_chip driver at the same time. This is also deployed in the Intel Merrifield driver. New drivers: - RDA Micro GPIO controller. - XGS-iproc GPIO driver.

Pull clk updates from Stephen Boyd: "This merge window we have one small clk provider API in the core framework and then a bunch of driver updates and a handful of new drivers. In terms of diffstat the Qualcomm and Amlogic drivers are high up there because of all the clk data introcued by new drivers. The Nvidia Tegra driver had a lot of work done this cycle too to support suspend/resume and memory controllers. And the OMAP clk driver got proper clk and reset handling in place. Rounding out the patches are various updates to remove unused data, mark things static, correct incorrect data in drivers, etc. All the little things that improve drivers and maintain code health. I will point out that there's a patch in here for the GPIO clk driver, that almost nobody uses, which changes behavior and causes clk_set_rate() to try to change the GPIO gate clk's parent. Other than that things are fairly well SoC specific here.

Pull y2038 cleanups from Arnd Bergmann: "y2038 syscall implementation cleanups This is a series of cleanups for the y2038 work, mostly intended for namespace cleaning: the kernel defines the traditional time_t, timeval and timespec types that often lead to y2038-unsafe code. Even though the unsafe usage is mostly gone from the kernel, having the types and associated functions around means that we can still grow new users, and that we may be missing conversions to safe types that actually matter. There are still a number of driver specific patches needed to get the last users of these types removed, those have been submitted to the respective maintainers" Link: https://lore.kernel.org/lkml/20191108210236.1296047-1-arnd@arndb.de/ * tag 'y2038-cleanups-5.5' of git://git.kernel.org:/pub/scm/linux/kernel/git/arnd/playground: (26 commits) y2038: alarm: fix half-second cut-off y2038: ipc: fix x32 ABI breakage y2038: fix typo in powerpc vdso "LOPART" y2038: allow disabling time32 system calls y2038: itimer: change implementation to timespec64 y2038: move itimer reset into itimer.c y2038: use compat_{get,set}_itimer on alpha y2038: itimer: compat handling to itimer.c y2038: time: avoid timespec usage in settimeofday() y2038: timerfd: Use timespec64 internally y2038: elfcore: Use __kernel_old_timeval for process times y2038: make ns_to_compat_timeval use __kernel_old_timeval y2038: socket: use __kernel_old_timespec instead of timespec y2038: socket: remove timespec reference in timestamping y2038: syscalls: change remaining timeval to __kernel_old_timeval y2038: rusage: use __kernel_old_timeval y2038: uapi: change __kernel_time_t to __kernel_old_time_t y2038: stat: avoid 'time_t' in 'struct stat' y2038: ipc: remove __kernel_time_t reference from headers y2038: vdso: powerpc: avoid timespec references ...

Pull removal of most of fs/compat_ioctl.c from Arnd Bergmann: "As part of the cleanup of some remaining y2038 issues, I came to fs/compat_ioctl.c, which still has a couple of commands that need support for time64_t. In completely unrelated work, I spent time on cleaning up parts of this file in the past, moving things out into drivers instead. After Al Viro reviewed an earlier version of this series and did a lot more of that cleanup, I decided to try to completely eliminate the rest of it and move it all into drivers. This series incorporates some of Al's work and many patches of my own, but in the end stops short of actually removing the last part, which is the scsi ioctl handlers.

Pull sysctl system call removal from Eric Biederman: "As far as I can tell we have reached the point where no one enables the sysctl system call anymore. It still is enabled in a few defconfigs but they are mostly the rarely used one and in asking people about that it was more cut & paste enabled than anything else. This is single commit that just deletes code. Leaving just enough code so that the deprecated sysctl warning continues to be printed. If my analysis turns out to be wrong and someone actually cares it will be easy to revert this commit and have the system call again. There was one new xtensa defconfig in linux-next that enabled the system call this cycle and when asked about it the maintainer of the code replied that it was not enabled on purpose. As of today's linux-next tree that defconfig no longer enables the system call. What we saw in the review discussion was that if we go a step farther than my patch and mess with uapi headers there are pieces of code that won't compile, but nothing minds the system call actually disappearing from the kernel" Link: https://lore.kernel.org/lkml/201910011140.EA0181F13@keescook/ * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: sysctl: Remove the sysctl system call

Pull powerpc updates from Michael Ellerman: "Highlights: - Infrastructure for secure boot on some bare metal Power9 machines. The firmware support is still in development, so the code here won't actually activate secure boot on any existing systems. - A change to xmon (our crash handler / pseudo-debugger) to restrict it to read-only mode when the kernel is lockdown'ed, otherwise it's trivial to drop into xmon and modify kernel data, such as the lockdown state. - Support for KASLR on 32-bit BookE machines (Freescale / NXP). - Fixes for our flush_icache_range() and __kernel_sync_dicache() (VDSO) to work with memory ranges >4GB. - Some reworks of the pseries CMM (Cooperative Memory Management) driver to make it behave more like other balloon drivers and enable some cleanups of generic mm code. - A series of fixes to our hardware breakpoint support to properly handle unaligned watchpoint addresses.

Merge tag 'notifications-pipe-prep-20191115' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs Pull pipe rework from David Howells: "This is my set of preparatory patches for building a general notification queue on top of pipes. It makes a number of significant changes: - It removes the nr_exclusive argument from __wake_up_sync_key() as this is always 1. This prepares for the next step: - Adds wake_up_interruptible_sync_poll_locked() so that poll can be woken up from a function that's holding the poll waitqueue spinlock. - Change the pipe buffer ring to be managed in terms of unbounded head and tail indices rather than bounded index and length. This means that reading the pipe only needs to modify one index, not two. - A selection of helper functions are provided to query the state of the pipe buffer, plus a couple to apply updates to the pipe indices. - The pipe ring is allowed to have kernel-reserved slots. This allows many notification messages to be spliced in by the kernel without allowing userspace to pin too many pages if it writes to the same pipe. - Advance the head and tail indices inside the pipe waitqueue lock and use wake_up_interruptible_sync_poll_locked() to poke poll without having to take the lock twice. - Rearrange pipe_write() to preallocate the buffer it is going to write into and then drop the spinlock. This allows kernel notifications to then be added the ring whilst it is filling the buffer it allocated. The read side is stalled because the pipe mutex is still held. - Don't wake up readers on a pipe if there was already data in it when we added more. - Don't wake up writers on a pipe if the ring wasn't full before we removed a buffer" * tag 'notifications-pipe-prep-20191115' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs: pipe: Remove sync on wake_ups pipe: Increase the writer-wakeup threshold to reduce context-switch count pipe: Check for ring full inside of the spinlock in pipe_write() pipe: Remove redundant wakeup from pipe_write() pipe: Rearrange sequence in pipe_write() to preallocate slot pipe: Conditionalise wakeup in pipe_read() pipe: Advance tail pointer inside of wait spinlock in pipe_read() pipe: Allow pipes to have kernel-reserved slots pipe: Use head and tail pointers for the ring, not cursor and length Add wake_up_interruptible_sync_poll_locked() Remove the nr_exclusive argument from __wake_up_sync_key() pipe: Reduce #inclusion of pipe_fs_i.h
