===== Areas that I work on =====

==== Security ====

  * MAC modules
    * Verified execution - a.k.a. veriexec [[https://github.com/hackagadget/freebsd/tree/hackagadget/veriexec]]
      * TODO
        * Clean up meta-data store code to be MP-safe
        * Determine ways to support FIPS mode
  * RNG driver for the RPi/RPi2
    * Committed as [[https://svnweb.freebsd.org/base/head/sys/arm/broadcom/bcm2835/bcm2835_rng.c?revision=303035|GRN 303035]]
  * TODO
    * Mark some DDB commands as not allowed in secure mode
      * Also allow for disabling same DDB commands via kernel configuration option
      * Maybe separate those out in source files so they could be added via a kernel module instead

==== Networking ====

  * Network stack as a module [[https://github.com/hackagadget/freebsd/tree/hackagadget/netstack]]
    * Able to pre-load network stack as a module from the loader (GitHub tree not completely up to date with prototype sources yet.)
    * Slide deck from BSDCan 2016 [[https://people.freebsd.org/~stevek/netstack/Netstack%20as%20Module%20-%20BSDCan%202016.pptx|PowerPoint (.pptx)]] [[https://people.freebsd.org/~stevek/netstack/Netstack%20as%20Module%20-%20BSDCan%202016.pdf|PDF]]
    * Demo video [[https://people.freebsd.org/~stevek/netstack/FreeBSD-NO_NET.m4v|FreeBSD-NO_NET.m4v]]
    * TODO
      * Allow for registering/deregistering protocol domains
      * Allow for registering/deregistering ioctl groups
      * Unwind the IPv4 and IPv6 bits from jails
      * VNET support
      * Load and unload of netstack module (with kldload and kldunload)
      * Multiple network stack instances and association with processes/jails/etc.

==== File Systems ====

  * Tarball file system (tarfs) [[https://github.com/hackagadget/freebsd/tree/hackagadget/tarfs]]
    * Able to mount uncompressed tarballs
    * TODO
      * Support for xz compressed tarballs
      * Support for PAX format with extended headers
      * Internationalization support

==== Boot Loader ====

  * Upgrade to Ficl4 [[https://github.com/hackagadget/freebsd/tree/hackagadget/ficl4]]
    * Still needs some work on the memory management side (to grow the heap when necessary)
  * Extensions for network loading and installation
  * User space loader testing (work in progress)
