Overview

Invoked tracee-ebpf events from user mode

This utility can be useful to generate information needed by signatures that is not provided by normal events in the kernel.

Because the events in the kernel are invoked by other programs behavior, we cannot anticipate which events will be invoked and as a result what information will be extracted.

This is critical because tracee-rules is independent, and doesn't have to run on the same machine as tracee-ebpf. This means that tracee-rules might lack basic information of the operating machine needed for some signatures.

By creating user mode events this information could be intentionally collected and passed to tracee-ebpf afterwards.

var SyscallSymbolNames = map[ID][]KernelRestrictions{}/* 452 elements not displayed */

SyscallSymbolNames mapping of syscall id to syscall definition name by kernel version. Since syscalls can be removed, changed or added - to run on every kernel out there, we need to address the changes over the kernel versions.
