inet_diag: fix reporting cgroup classid and fallback to priority

2019-02-27T09:08:58+00:00

[ Upstream commit 1ec17dbd90f8b638f41ee650558609c1af63dfa0 ] Field idiag_ext in struct inet_diag_req_v2 used as bitmap of requested extensions has only 8 bits. Thus extensions starting from DCTCPINFO cannot be requested directly. Some of them included into response unconditionally or hook into some of lower 8 bits. Extension INET_DIAG_CLASS_ID has not way to request from the beginning. This patch bundle it with INET_DIAG_TCLASS (ipv6 tos), fixes space reservation, and documents behavior for other extensions. Also this patch adds fallback to reporting socket priority. This filed is more widely used for traffic classification because ipv4 sockets automatically maps TOS to priority and default qdisc pfifo_fast knows about that. But priority could be changed via setsockopt SO_PRIORITY so INET_DIAG_TOS isn't enough for predicting class. Also cgroup2 obsoletes net_cls classid (it always zero), but we cannot reuse this field for reporting cgroup2 id because it is 64-bit (ino+gen). So, after this patch INET_DIAG_CLASS_ID will report socket priority for most common setup when net_cls isn't set and/or cgroup2 in use.

Input: input_event - provide override for sparc64

2019-01-31T07:14:37+00:00

commit 2e746942ebacf1565caa72cf980745e5ce297c48 upstream. The usec part of the timeval is defined as __kernel_suseconds_t tv_usec; /* microseconds */ Arnd noticed that sparc64 is the only architecture that defines __kernel_suseconds_t as int rather than long. This breaks the current y2038 fix for kernel as we only access and define the timeval struct for non-kernel use cases. But, this was hidden by an another typo in the use of __KERNEL__ qualifier. Fix the typo, and provide an override for sparc64.

peci: Add support for PECI bus driver core

2019-01-03T04:22:57+00:00

This commit adds driver implementation for PECI bus core into linux driver framework. PECI (Platform Environment Control Interface) is a one-wire bus interface that provides a communication channel from Intel processors and chipset components to external monitoring or control devices. PECI is designed to support the following sideband functions: * Processor and DRAM thermal management - Processor fan speed control is managed by comparing Digital Thermal Sensor (DTS) thermal readings acquired via PECI against the processor-specific fan speed control reference point, or TCONTROL. Both TCONTROL and DTS thermal readings are accessible via the processor PECI client. These variables are referenced to a common temperature, the TCC activation point, and are both defined as negative offsets from that reference. - PECI based access to the processor package configuration space provides a means for Baseboard Management Controllers (BMC) or other platform management devices to actively manage the processor and memory power and thermal features. * Platform Manageability - Platform manageability functions including thermal, power, and error monitoring. Note that platform 'power' management includes monitoring and control for both the processor and DRAM subsystem to assist with data center power limiting. - PECI allows read access to certain error registers in the processor MSR space and status monitoring registers in the PCI configuration space within the processor and downstream devices. - PECI permits writes to certain registers in the processor PCI configuration space. * Processor Interface Tuning and Diagnostics - Processor interface tuning and diagnostics capabilities (Intel Interconnect BIST). The processors Intel Interconnect Built In Self Test (Intel IBIST) allows for infield diagnostic capabilities in the Intel UPI and memory controller interfaces. PECI provides a port to execute these diagnostics via its PCI Configuration read and write capabilities. * Failure Analysis - Output the state of the processor after a failure for analysis via Crashdump. PECI uses a single wire for self-clocking and data transfer. The bus requires no additional control lines. The physical layer is a self-clocked one-wire bus that begins each bit with a driven, rising edge from an idle level near zero volts. The duration of the signal driven high depends on whether the bit value is a logic '0' or logic '1'. PECI also includes variable data transfer rate established with every message. In this way, it is highly flexible even though underlying logic is simple. The interface design was optimized for interfacing between an Intel processor and chipset components in both single processor and multiple processor environments. The single wire interface provides low board routing overhead for the multiple load connections in the congested routing area near the processor and chipset components. Bus speed, error checking, and low protocol overhead provides adequate link bandwidth and reliability to transfer critical device operating conditions and configuration information. This implementation provides the basic framework to add PECI extensions to the Linux bus and device models. A hardware specific 'Adapter' driver can be attached to the PECI bus to provide sideband functions described above. It is also possible to access all devices on an adapter from userspace through the /dev interface. A device specific 'Client' driver also can be attached to the PECI bus so each processor client's features can be supported by the 'Client' driver through an adapter connection in the bus.
