Andriy Gapon bdc44f62ff 7431 ZFS Channel Programs 
illumos/illumos-gate@dfc115332c

https://www.illumos.org/issues/7431
  ZFS channel programs (ZCP) adds support for performing compound ZFS
  administrative actions via Lua scripts in a sandboxed environment (with time
  and memory limits).
  This initial commit includes both base support for running ZCP scripts, and a
  small initial library of API calls which support getting properties and
  listing, destroying, and promoting datasets.
  Testing: in addition to the included unit tests, channel programs have been in
  use at Delphix for several months for batch destroying filesystems. The
  dsl_destroy_snaps_nvl() call has also been replaced with

  For reference, the new zfs-program manpage is included below.
  ZFS-PROGRAM(1M)                       1M                       ZFS-PROGRAM(1M)

  NAME
       zfs program – executes ZFS channel programs

  SYNOPSIS
       zfs program [-t timeout] [-m memory-limit] pool script

  DESCRIPTION
       The ZFS channel program interface allows ZFS administrative operations to
       be run programmatically as a Lua script. The entire script is executed
       atomically, with no other administrative operations taking effect
       concurrently. A library of ZFS calls is made available to channel program
       scripts. Channel programs may only be run with root privileges.

       A modified version of the Lua 5.2 interpreter is used to run channel
       program scripts. The Lua 5.2 manual can be found at:
