This makes unix:tmpdir=... equivalent to + unix:dir=... on all platforms. + Previous versions would have created an abstract socket, unix:abstract=..., + in this situation. + This change primarily affects the well-known session bus when run via + dbus-launch(1) or dbus-run-session(1). The user bus, enabled by configuring + dbus with --enable-user-session and running it on a systemd system, + already used path-based Unix sockets and is unaffected by this change. + This behaviour change prevents a sandbox escape via the session bus socket + in sandboxing frameworks that can share the network namespace with the host + system, such as Flatpak. + This change might cause a regression in situations where the abstract socket + is intentionally shared between the host system and a chroot or container, + such as some use-cases of schroot(1). That regression can be resolved by + using a bind-mount to share either the D-Bus socket, or the whole /tmp + directory, with the chroot or container. + (dbus#416, Simon McVittie) dbus 1.15.0 (2022-09-22) ======================== |
