    • it's not only about Debian anymore…
      • +
    +
    + + +
    +

    The problem: Can we trust the build process?

    +
      +
    • One can inspect the source code of free software for flaws
      • +
    • But distributions provide binary/compiled packages
      • +
    +
    + +
    +

    The problem: nobody can trust any binary built anywhere anymore

    + +
      +
    • To get users, go after the developers
      • +
    • Financial incentives to crack developer machines / build infrastructure
      • +
    • CVE-2002-0083: Remote root exploit in OpenSSH (single bit difference in binary)
      • +
    • Kernel module modifying source code when "viewed" by GCC only (see media.ccc.de)
      • +
    • Compromised Apple iOS SDK, Xcodeghost, etc.
      • +
    +
    + +
    +

    Our solution

    +
      (we are still at step 1 here) +
    • Ensure compilation of the same source always has bit by bit identical results
      • +
    • Multiple parties compare compilation results
      • +
    • Attacker needs to infect everybody simultaneously (or they are detected)
      • +
    +
    + +
    +

    We call this Reproducible Builds.

    + +
      +
    • We think this should become the norm for free software.
      • +
    +
    + +
    +

    + The motivation behind "reproducible" builds is to allow verification + that no flaws have been introduced during the compilation process. +

    +
    + + +
    +

    Reproducible builds in Debian

    + +

    Continuously build every package twice, varying:

    + +
      +
        +
      • Time & date
        • +
      • Hostname & domain name
        • +
      • Filesystem (disorderfs)
        • +
      • Timezone & locale
        • +
      • uid & gid
        • +
      • GECOS information, the shell & a bunch of environment variables
        • +
      • Kernel & CPU type
        • +
      • and more…

    Challenges

    +
      +
        +
      • Timestamps
        • +
      • Timezones & locales
        • +
      • Non-deterministic file ordering
        • +
      • Dictionary/hash key ordering
        • +
      • Users, groups, umask, environment variables
        • +
      • Build paths
        • +
      • Specifying the environment
        • +
      +
    +
    + +
    +   +
    + +
    +   +
    + +
    +

    Other technical benefits

    + +
      +
        +
      • Faster to build; saves time, money & the environment
        • +
      • Easier to test changes/revisions
        • +
      • Unsafe behaviour (eg. internet access)
        • +
      • Unreliable / non-deterministic behaviours (eg. timing)
        • +
      • Finds bugs in uncommon timezones or locales
        • +
      • Detect corrupted build environments
        • +
      • Find future build failures (eg. expired certificates)
        • +
      +
    +
    + + +
    +   +
    + + +
    +

    Future work

    + +
      +
    • .buildinfo files distribution unsolved (step 2)
      • +
    • How to make it meaningful for end-users (step 3)
      • +
    • Source code still vulnerable
      • +
    +
