Dear Andy, Kees, Will, dear kernel community, With 5.8-rc3 there is a seccomp related crash which prevents Chromium and QtWebEngine from starting: Bug 208369 - seccomp crash with Chromium, QtWebEngine and related browsers: seccomp-bpf failure in syscall 0072 https://bugzilla.kernel.org/show_bug.cgi?id=208369 Reverting to 5.8-rc2 fixes the issue. Best, -- Martin

Hi, It looks like this is from e9c15badbb7b ("fs: Do not check if there is a fsnotify watcher on pseudo inodes") Currently being discussed here: https://lore.kernel.org/lkml/7b4aa1e985007c6d582fffe5e8435f8153e28e0f.ca...@redhat.com/#r -- Kees Cook
