  • 3.6.12 and 3.5.15 were chemspills to address an active exploit

Things that went right

  • Quick response on off-hours
  • Worked well with AV vendors and Google to mitigate the attack
  • RelEng had IT start staging for mirrors differently, speeding up the process
  • Virtually no mechanics hiccups/problems during build, qualification, and release
  • < 48 hours to release

Things that went wrong

  • A patch reviewers were away at Facebook, delaying the review and subsequent final patch
  • Christian pushed the build to mirrors before QA had signed off
    • He made the decsision the trade-offs were worth it
    • He didn't discuss this with QA

Suggested Improvements

  • Christian will discuss all process changes over the release-drivers mailing list

  • QA will get new hardware to support update testing multiple releases in parallel
    • Should give ~50% speed up in update qualification
