What issue are you seeing?

codex-cli 0.84.0’s workspace-write sandbox uses unprivileged user namespaces + Landlock. On this machine it fails during sandbox setup because it can’t write /proc/self/
setgroups (EACCES), so Codex can’t sandbox-run commands and keeps escalating them for approval (which feels like “approve everything”).

  • You can reproduce the root cause with codex sandbox linux --full-auto true (it panics with “error running landlock: Permission denied”). This box also has

kernel.apparmor_restrict_unprivileged_userns = 1, which is consistent with that failure.

What steps can reproduce the bug?
