magic-trace collects and displays high-resolution traces of what a process is doing

You use it like perf: point it to a process and off it goes. The key difference from perf is that instead of sampling call stacks throughout time, magic-trace uses Intel Processor Trace to snapshot a ring buffer of all control flow leading up to a chosen point in time1. Then, you can explore an interactive timeline of what happened.

You can point magic-trace at a function such that when your application calls it, magic-trace takes a snapshot. Alternatively, attach it to a running process and detatch it with Ctrl+C, to see a trace of an arbitrary point in your program.

Unprivileged sandboxing tool

Many container runtime tools like systemd-nspawn, docker, etc. focus on providing infrastructure for system administrators and orchestration tools (e.g. Kubernetes) to run containers.

These tools are not suitable to give to unprivileged users, because it is trivial to turn such access into a fully privileged root shell on the host.

Bubblewrap could be viewed as setuid implementation of a subset of user namespaces. Emphasis on subset - specifically relevant to the above CVE, bubblewrap does not allow control over iptables.

bubblewrap works by creating a new, completely empty, mount namespace where the root is on a tmpfs that is invisible from the host, and will be automatically cleaned up when the last process exits. You can then use commandline options to construct the root filesystem and process environment and command to run in the namespace.
