2017-06-13usb: Fix typo in the definition of Endpoint[out]RequestBenjamin Herrenschmidt

2017-06-13USB: add usbfs ioctl to retrieve the connection speedAlan Stern
The usbfs interface does not provide any way for the user to learn the speed at which a device is connected. The current API includes a USBDEVFS_CONNECTINFO ioctl, but all it provides is the device's address and a one-bit value indicating whether the connection is low speed. That may have sufficed in the era of USB-1.1, but it isn't good enough today. This patch introduces a new ioctl, USBDEVFS_GET_SPEED, which returns a numeric value indicating the speed of the connection: unknown, low, full, high, wireless, super, or super-plus. Similar information (not exactly the same) is available through sysfs, but it seems reasonable to provide the actual value in usbfs.

2017-06-13cfg80211: support 4-way handshake offloading for WPA/WPA2-PSKEliad Peller
Let drivers advertise support for station-mode 4-way handshake offloading with a new NL80211_EXT_FEATURE_4WAY_HANDSHAKE_STA_PSK flag. Extend use of NL80211_ATTR_PMK attribute indicating it might be passed as part of NL80211_CMD_CONNECT command, and contain the PSK (which is the PMK, hence the name.) The driver/device is assumed to handle the 4-way handshake by itself in this case (including key derivations, etc.), instead of relying on the supplicant.

2017-06-12scsi: Protect SCSI device state changes with a mutexBart Van Assche
Serializing SCSI device state changes avoids that two state changes can occur concurrently, e.g. the state changes in scsi_target_block() and __scsi_remove_device(). This serialization is essential to make patch "Make __scsi_remove_device go straight from BLOCKED to DEL" work reliably. Enable this mechanism for all scsi_target_*block() callers but not for the scsi_internal_device_unblock() calls from the mpt3sas driver because that driver can call scsi_internal_device_unblock() from atomic context.

2017-06-12scsi: Avoid that scsi_exit_rq() triggers a use-after-freeBart Van Assche
Dereferencing shost from scsi_exit_rq() is not safe because the SCSI host may already have been freed when scsi_exit_rq() is called. Increasing the shost reference count in scsi_init_rq() and dropping that reference in scsi_exit_rq() is nontrivial since scsi_host_dev_release() may sleep and since scsi_exit_rq() may be called from interrupt context. Since scsi_exit_rq() only needs a single bit from shost, copy that bit into struct scsi_cmnd.

2017-06-12udp: avoid a cache miss on dequeuePaolo Abeni
Since UDP no more uses sk->destructor, we can clear completely the skb head state before enqueuing. Amend and use skb_release_head_state() for that. All head states share a single cacheline, which is not normally used/accesses on dequeue. We can avoid entirely accessing such cacheline implementing and using in the UDP code a specialized skb free helper which ignores the skb head state. This saves a cacheline miss at skb deallocation time. v1 -> v2: replaced secpath_reset() with skb_release_head_state() Signed-off-by: Paolo Abeni <pabeni@redhat.com> Acked-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.

The format of this new resource is: PinGroupConfig (Shared/Exclusive, PinConfigType, PinConfigValue, ResourceSource, ResourceSourceIndex, ResourceSourceLabel, ResourceUsage, DescriptorName, VendorData) The PinConfigType/PinConfigValue are the same used by PinConfig() resource. Here also the combination of ResourceSource and ResourceSourceLabel is used to specify the PinGroup() this resource refers to.

ACPICA commit bd9a745749eac7137cd23085e6bdeb322de14ea2 PinGroupFunction() is a new resource introduced with ACPI 6.2. It is used with PinGroup() to configure specific mode for a set of pins exposed by a GPIO controller. The format of the resource is: PinGroupFunction (Shared/Exclusive, FunctionNumber, ResourceSource, ResourceSourceIndex, ResourceSourceLabel, ResourceUsage, DescriptorName, VendorData) The resource_source and ResourceSourceLabel fields are used to specify the PinGroup() resource referenced by PinGroupFunction(). Device (GPIO) { Name (_CRS, ResourceTemplate () { PinGroup ("group1") {2, 3} PinGroup ("group2") {4, 5} ... }) } Device (I2C) { Name (_CRS, ResourceTemplate () { PinGroupFunction (Exclusive, 6, "^GPIO", 0, "mygroup2") }) } In the above example the PinGroupFunction() references the second PinGroup() resource (using label "mygroup2" and configures pins 4 and 5 into mode 6.

ACPICA commit a06fdba686cefccd5dd5b93b52fa0f1e3f984906 ACPI 6.2 introduced a new resource that is used to specify fine-grained configuration of a pin or set of pins used by a device. The ASL syntax of this new resource looks like: PinConfig (Shared/Exclusive, PinConfigType, PinConfigValue, ResourceSource, ResourceSourceIndex, ResourceUsage, DescriptorName, Vendordata) {Pin List} PinConfigType is an integer with following accepted values: 0x00 (Default) - No configuration is applied to the pin 0x01 (Bias Pull-up) - Pin is pulled up using certain size resistor 0x02 (Bias Pull-down) - Pin is pulled down using certain size resistor 0x03 (Bias Default) - Set to default biasing 0x04 (Bias Disable) - All bias settings will be disabled 0x05 (Bias High Impedance) - Configure the pin as hi_z 0x06 (Bias Bus Hold) - Configure the pin in a weak latch state where it drives the last value on a tristate bus 0x07 (Drive Open Drain) - Configure the pin into open drain state 0x08 (Drive Open Source) - Configure the pin into open source state 0x09 (Drive Push Pull) - Configure the pin into push-pull state 0x0a (Drive Strength) - How much the pin can supply current 0x0b (Slew Rate) - Configure slew rate of the pin 0x0c (Input Debounce) - Enable input debouncer for the pin 0x0d (Input Schmitt Trigger) - Enable schmitt trigger for the pin 0x0e - 0x7f - Reserved 0x80 - 0xff - Vendor defined types The PinConfigValue depends on the type and is expressed as units suitable for that type (for example bias uses Ohms).

2017-06-12ACPICA: Tables: Mechanism to handle late stage acpi_get_table() imbalanceLv Zheng
Considering this case: 1. A program opens a sysfs table file 65535 times, it can increase validation_count and first increment cause the table to be mapped: validation_count = 65535 2. AML execution causes "Load" to be executed on the same table, this time it cannot increase validation_count, so validation_count remains: validation_count = 65535 3. The program closes sysfs table file 65535 times, it can decrease validation_count and the last decrement cause the table to be unmapped: validation_count = 0 4. AML code still accessing the loaded table, kernel crash can be observed. To prevent that from happening, add a validation_count threashold. When it is reached, the validation_count can no longer be incremented/decremented to invalidate the table descriptor (means preventing table unmappings) Note that code added in acpi_tb_put_table() is actually a no-op but changes the warning message into a "warn once" one.

2017-06-12soc: renesas: Rework Kconfig and Makefile logicGeert Uytterhoeven
The goals are to: - Allow precise control over and automatic selection of which (sub)drivers are used for which SoC, - Allow adding support for new SoCs easily, - Allow compile-testing of all (sub)drivers, - Keep driver selection logic in the subsystem-specific Kconfig, independent from the architecture-specific Kconfig (i.e. no "select" from arch/arm64/Kconfig.platforms), to avoid dependencies. This is implemented by: - Introducing Kconfig symbols for all drivers and sub-drivers, - Introducing the Kconfig symbol SOC_RENESAS, which is enabled automatically when building for a Renesas ARM platform, and which enables all required drivers without interaction of the user, based on SoC-specific ARCH_* symbols, - Allowing the user to enable any Kconfig symbol manually if COMPILE_TEST is enabled, - Using the new Kconfig symbols instead of the ARCH_* symbols to control compilation in the Makefile, - Always entering drivers/soc/renesas/ during the build.
