Sysdig CCWFS 2016 - Session 2 - A brief history of syscalls - Adam Leventhal

Adam Leventhal traces the history of system calls and system call observability tools from early Unix to modern systems.

System calls are the primary mechanism of user-to-kernel interaction. Today the Linux system call interface has achieved a primacy and ubiquity that make it an ideal layer at which to understand single-system and distributed-system pathologies. Sysdig advances the art of system call observability by drawing on the systems that came before it. Informed by his work with /proc, process tools and DTrace, Adam Leventhal walks through a history of system calls and system call observability from simple systems like truss and strace, moderns ones like DTrace and SystemTab, and ancient ones from the early days of Unix.
