Introduction to Introduction to the FreeBSD Open Source Operating System LiveLessonsLesson 1: Introduction to the FreeBSD Community
Lesson 1 describes the way that the FreeBSD community is organized and the way in which it designs, builds, and manages its distributions. The lesson concludes by describing the best use cases for FreeBSD versus Linux.Lesson 2: Introduction to the Kernel
Lesson 2 provides an introduction to the FreeBSD kernel. It introduces the user process as the central facility that the kernel provides. It shows how a user process communicates with the kernel through the system call interface and uses kernel-based timers to synchronize time-based events. The lesson concludes with a description of the locking mechanisms that the kernel uses to control access to its data structures.Lesson 3: Processes
Lesson 3 begins by detailing the components that describe a user process. It then outlines the facilities that the kernel provides to support user processes. These facilities include the scheduler that controls when processes get to run, the signal infrastructure for delivering asynchronous events to processes, and the group and session mechanisms for organizing sets of related processes. The lesson concludes by explaining the use of jails as a lightweight virtualization facility.
Lesson 4: Virtual Memory
Lesson 4 explains the management of the virtual memory used by a process. It starts by describing the layout of a process in its virtual memory and shows how the virtual memory is backed by physical memory, swap space, and executable files and libraries in the filesystem. Next it describes the different types of regions that make up an address space and shows how the kernel tracks and manages these regions. It concludes by explaining how the kernel manages the physical memory both for its own use and on behalf of the user processes.
Lesson 5: I/O System Overview
Lesson 5 examines the kernel from the perspective of its I/O hierarchy. It starts by detailing the data structures used by the kernel to describe I/O requests. It then shows how the kernel exports the capability to multiplex I/O operations to user processes. It describes the data structures used to manage the socket, file, and device I/O descriptors for a process. It concludes by motivating the addition of a virtual filesystem interface and describing the virtual file (vnode) data structure and associated support facilities provided for using the virtual filesystem interface.
Lesson 6: Devices
Lesson 6 gives you an overview of how the kernel manages devices. It introduces the special device concept including the mechanisms for naming and controlling access to devices. Next it describes the volume management and disk I/O-subsystem frameworks. It concludes by showing how devices are initially identified and made available for user processes to use.
Lesson 7: The Fast Filesystem
Lesson 7 begins with a multi-decade history describing the evolution of the local FreeBSD filesystem. It reviews the kernel data structures that link from the user-process file descriptor to the local filesystem’s inode data structure used to control access to and describe the location of a file on disk. Next it describes how the kernel optimizes both the I/O to a file and the layout of the file on the disk. It concludes by describing the requirements for maintaining filesystem consistency in the face of either a hardware or a software crash and the various strategies that are used to implement these requirements.
Lesson 8: The ZFS Filesystem
Lesson 8 presents an overview of the Zettabyte filesystem (ZFS) imported from Open Solaris to FreeBSD. It introduces the modules that make up ZFS and describes their functional and structural organization.
Lesson 9: Networking and Interprocess Communication
Lesson 9 introduces the networking and interprocess communications facilities of FreeBSD. It starts by showing how data flows end-to-end between two user-process sockets through the TCP/IP protocols. It then describes the socket and network protocol structures, the mbuf data buffers used to hold the data packets as they flow through the network, and the interface to the networking hardware. Next it explains the migration from version 4 to version 6 of the IP protocol. It concludes with a discussion of the design of and strategies for routing packets through the network.
