2017-11-28serdev: fix receive_buf return value when no callbackJohan Hovold1-1/+1
The receive_buf callback is supposed to return the number of bytes processed and should specifically not return a negative errno. Due to missing sanity checks in the serdev tty-port controller, a driver not providing a receive_buf callback could cause the flush_to_ldisc() worker to spin in a tight loop when the tty buffer pointers are incremented with -EINVAL (-22). The missing sanity checks have now been added to the tty-port controller, but let's fix up the serdev-controller helper as well.

2017-11-28debugfs: fix debugfs_real_fops() build errorArnd Bergmann1-0/+2
Some drivers use debugfs_real_fops() even when CONFIG_DEBUG_FS is disabled, which now leads to a build error: In file included from include/linux/list.h:9:0, from include/linux/wait.h:7, from include/linux/wait_bit.h:8, from include/linux/fs.h:6, from drivers/net/wireless/broadcom/b43legacy/debugfs.c:26: drivers/net/wireless/broadcom/b43legacy/debugfs.c: In function 'b43legacy_debugfs_read': drivers/net/wireless/broadcom/b43legacy/debugfs.c:224:23: error: implicit declaration of function 'debugfs_real_fops'; did you mean 'debugfs_create_bool'? [-Werror=implicit-function-declaration] My first impulse was to add another 'static inline' dummy function returning NULL for it, which would work fine. However, most callers feed the pointer into container_of(), so it seems a little dangerous here. Since all the callers are inside of a read/write file operation that gets eliminated in this configuration, so having an 'extern' declaration seems better here. If it ever gets used in a dangerous way, that will now result in a link error.

As most of BOS descriptors are longer in length than their header 'struct usb_dev_cap_header', comparing solely with it is not sufficient to avoid out-of-bounds access to BOS descriptors.

Clean up the USB device-node helper that is used to look up a device node given a parent hub device and a port number. Also pass in a struct usb_device as first argument to provide some type checking. Give the helper the more descriptive name usb_of_get_device_node(), which matches the new usb_of_get_interface_node() helper that is used to look up a second type of of child node from a USB device. Note that the terms "device node" and "interface node" are defined and used by the OF Recommended Practice for USB.

2017-11-28USB: add device-tree support for interfacesJohan Hovold1-0/+14
Add OF device-tree support for USB interfaces. USB "interface nodes" are children of USB "device nodes" and are identified by an interface number and a configuration value: &usb1 { /* host controller */ dev1: device@1 { /* device at port 1 */ compatible = "usb1234,5678"; reg = <1>; #address-cells = <2>; #size-cells = <0>; interface@0,2 { /* interface 0 of configuration 2 */ compatible = "usbif1234,5678.config2.0"; reg = <0 2>; }; }; }; The configuration component is not included in the textual representation of an interface-node unit address for configuration 1: &dev1 { interface@0 { /* interface 0 of configuration 1 */ compatible = "usbif1234,5678.config1.0"; reg = <0 1>; }; }; When a USB device of class 0 or 9 (hub) has only a single configuration with a single interface, a special case "combined node" is used instead of a device node with an interface node: &usb1 { device@2 { compatible = "usb1234,abcd"; reg = <2>; }; }; Combined nodes are shared by the two device structures representing the USB device and its interface in the kernel's device model. Note that, as for device nodes, the compatible strings for interface nodes are currently not used.

2017-11-27KVM: Let KVM_SET_SIGNAL_MASK work as advertisedJan H. Schönherr1-0/+3
KVM API says for the signal mask you set via KVM_SET_SIGNAL_MASK, that "any unblocked signal received [...] will cause KVM_RUN to return with -EINTR" and that "the signal will only be delivered if not blocked by the original signal mask". This, however, is only true, when the calling task has a signal handler registered for a signal. If not, signal evaluation is short-circuited for SIG_IGN and SIG_DFL, and the signal is either ignored without KVM_RUN returning or the whole process is terminated. Make KVM_SET_SIGNAL_MASK behave as advertised by utilizing logic similar to that in do_sigtimedwait() to avoid short-circuiting of signals. Signed-off-by: Jan H.

2017-11-27ACPI / PM: Make it possible to ignore the system sleep blacklistRafael J. Wysocki1-0/+1
The ACPI code supporting system transitions to sleep states uses an internal blacklist to apply special handling to some machines reported to behave incorrectly in some ways. However, some entries of that blacklist cover problematic as well as non-problematic systems, so give the users of the latter a chance to ignore the blacklist and run their systems in the default way by adding acpi_sleep=nobl to the kernel command line. For example, that allows the users of Dell XPS13 9360 systems not affected by the issue that caused the blacklist entry for this machine to be added by commit 71630b7a832f (ACPI / PM: Blacklist Low Power S0 Idle _DSM for Dell XPS13 9360) to use suspend-to-idle with the Low Power S0 Idle _DSM interface which in principle should be more energy-efficient than S3 on them.

2017-11-27PM / core: Add LEAVE_SUSPENDED driver flagRafael J. Wysocki1-4/+12
Define and document a new driver flag, DPM_FLAG_LEAVE_SUSPENDED, to instruct the PM core and middle-layer (bus type, PM domain, etc.) code that it is desirable to leave the device in runtime suspend after system-wide transitions to the working state (for example, the device may be slow to resume and it may be better to avoid resuming it right away). Generally, the middle-layer code involved in the handling of the device is expected to indicate to the PM core whether or not the device may be left in suspend with the help of the device's power.may_skip_resume status bit. That has to happen in the "noirq" phase of the preceding system suspend (or analogous) transition. The middle layer is then responsible for handling the device as appropriate in its "noirq" resume callback which is executed regardless of whether or not the device may be left suspended, but the other resume callbacks (except for ->complete) will be skipped automatically by the core if the device really can be left in suspend. The additional power.must_resume status bit introduced for the implementation of this mechanisn is used internally by the PM core to track the requirement to resume the device (which may depend on its children etc).

2017-11-27ACPICA: Dispatcher: Introduce timeout mechanism for infinite loop detectionLv Zheng3-4/+6
ACPICA commit 9605023e7e6d1f05581502766c8cf2905bcc03d9 This patch implements a new infinite loop detection mechanism to replace the old one, it uses acpi_os_get_timer() to limit loop execution into a determined time slice. This is useful in case some hardware/firmware operations really require the AML interpreter to wait while the old mechanism could expire too fast on recent machines. The new mechanism converts old acpi_gbl_max_loop_iterations to store the user configurable value for the new mechanism in order to allow users to be still able to configure this value for acpiexec via command line. This patch also removes wrong initilization code of acpi_gbl_max_loop_iterations accordingly (it should have been initialized by ACPI_INIT_GLOBAL, and the default value is also properly tuned for acpiexec).
