From 55fc280e951ab2b39f3dcb640edc1b1eebc6d173 Mon Sep 17 00:00:00 2001 From: "Rob Herring (Arm)" Date: Mon, 31 Aug 2026 14:43:51 -0500 Subject: Input: tsc2007 - read "ti,poll-period" as u32 The "ti,poll-period" property is documented as a normal uint32 cell. The driver used a u64 helper, which makes the helper type disagree with the schema even though the stored value is still small. Read "ti,poll-period" with the u32 helper matching the documented DT cell size.

It +is composed of three main components, the protocol engines, the communication +layer, and the kernel security module API. + +Protocol Engines +================ + +The protocol engines are responsible for both applying and retrieving the +network packet's security attributes. If any translation between the network +security attributes and those on the host are required then the protocol +engine will handle those tasks as well. Other kernel subsystems should +refrain from calling the protocol engines directly, instead they should use +the NetLabel kernel security module API described below. + +Detailed information about each NetLabel protocol engine can be found in this +directory. + +Communication Layer +=================== + +The communication layer exists to allow NetLabel configuration and monitoring +from user space. The NetLabel communication layer uses a message based +protocol built on top of the Generic NETLINK transport mechanism. The exact +formatting of these NetLabel messages as well as the Generic NETLINK family +names can be found in the 'net/netlabel/' directory as comments in the +header files as well as in 'include/net/netlabel.h'. + +Security Module API +=================== + +The purpose of the NetLabel security module API is to provide a protocol +independent interface to the underlying NetLabel protocol engines. In addition +to protocol independence, the security module API is designed to be completely +LSM independent which should allow multiple LSMs to leverage the same code +base. + +Detailed information about the NetLabel security module API can be found in the +'include/net/netlabel.h' header file as well as the 'lsm_interface.txt' file +found in this directory. -- cgit v1.3.1
