"Beautifying syscall args using kernel headers and eBPF in 'perf trace'.

There are many players driving the addition of features in the kernel to help observe events and filter voluminous information at the source, with the lowest overhead, making (or trying to make) sure that security is kept while helping developers cope with increasingly complex systems.

Showing examples of how these infrastructures can be used, in the kernel sources is the overall objective of tools/. Nevermind that what is there can actually be used to attack this complexity.

The perf trace is one such effort, to get the strace workflow and augment it with tracepoints, callchains, system wide, cgroup wide and other targets besides those accessible to the original strace, using the perf and eBPF is the goal here."
