Sockets in the Linux Kernel (2) - Rami Rosen

Abstract

Sockets in the Linux Kernel (2) We will deal with the implementation the following sockets in the Linux kernel:

• Raw sockets.
• Unix Domain sockets.
• Netlink sockets.
• SCTP sockets.

• how raw sockets are used in the familiar "ping" and "traceroute" utils.
• The usage of Unix domain sockets as an IPC (Inter process communication) mechanism.
• Netlink sockets as a messaging subsystem between kernel and userspace (including rtnetlink and generic netlink)
• examples demonstratting Netlink sockets usage
• SCTP sockets : one-to-one style and one-to-many style.
