flua: Add a libjail module

Authored by freqlabs on Aug 16 2020, 4:31 AM.



libjail is pretty small, so it makes for a good proof of concept demonstrating how a system library can be wrapped to create a loadable Lua module for flua.

Event Timeline

I plan to add documentation and Lua code examples. And I should add $FreeBSD$ and unshebangify lib/flua/libjail/Makefile

Does this really work? This should be controlled with a MK_ variables...

I took it from about 13 lines down where clang does something similar. The goal is to not build a lib32 compat version of the Lua modules. It does seem to be working.

  • Add an example for the jail module
  • Add a 3lua manpage section, with intro(3lua) and jail(3lua)
  • Add __FBSDID to the jail module
  • Unshebangify lib/flua/libjail/Makefile
freqlabs added reviewers: kevans, emaste.

Add 3lua section to contrib/mandoc/

I'd eventually like to be able to iterate over running jails, but this isn't necessary for a first pass.

You'll want to deconst this, as it needs to be free()d after it's pushed to the stack.

make analyze points out that this is a dead store, due to reassignment in the impending loop.
