First Prototype Implementation released

We just released the first working prototype! It is currently able to monitor events sent by the Linux kernel whenever a fork()/execve() syscall is executed, and subsequently scan the newly created process’ file mappings. Valid mappings are then mlocked() to the virtual memory of our precached process.

Prototype of precached running on Linux

TODO List (non-exhaustive):

• Implement ceiling on mlocked() memory
• Implement VFS statx() caching (pre-read file metadata)
• Possibly implement fork-bomb mitigation
• Implement a persistence layer
• Prime caches on daemon startup
• Systemd init scripts
• External configuration support (/etc/precached/)
• Daemonization support
• Implement the DBUS interface
• Write a nice CLI tool to control the daemon
• And write a precached GUI in GTK+
• And much more…
