  • Problems attaching debugger to sandboxed content processes
  • bug 1386404 Stop allowing Linux content processes to access /tmp

  • bug 1423628 - Stop processing native events in the content process
    • bug 1396984 - Scrollbar becomes black on first connection of second screen
      • Tracked it down to failing NtGdiDrawStream calls in DrawThemeBackground, can't see why they're failing at the moment.
    • bug 1430744 - Stop processing native events in the content process on Windows in Nightly
      • Just realised my patch doesn't check for NIghtly so need to add that and land.
  • bug 1421944 - Webrtc microphone input broken in Windows Insider Preview Build 17046
    • Fix in insider build and confirmed by original reporter.


  • bug 1243108 - Tried to repro the sendmsg bug in rr; rr is (understandably) slow on it; failed to repro. Might try running in a loop overnight.
  • bug 1151624 - Realized why pid namespace isolation was failing on Try, after it failed locally while dogfooding
    • The profiler / BackgroundHangMonitor uses tgkill(getpid(), …); I remapped in seccomp-bpf, but that doesn't help pre-sandbox
    • (It got ESRCH, failed a debug-only assertion, and locked up in a complicated way involving 3 different threads)
  • bug 1401062 - The clone bug could land, but I'm deferring it until post-59-freeze
    • Risk would be GMP-only, so we could easily miss problems until release
  • bug 1430949 - Filed separate bug for network namespace isolation
    • Investigated with LD_PRELOAD shim whether we're doing other socket stuff pre-sandbox (e.g., DBus), but I see only X
  • bug 1386019 - Wrote the rest of the miscellaneous-audio-stuff patch
  • bug 1430274 - …and realized that I broke ALSA in 58, but there's a bug from a few days ago with a patch

    • I have some ideas for tooling here.
