2016-06-09{machine,system}ctl: always pass &changes and &n_changes (#3350)Christian Hesse
We have to pass addresses of changes and n_changes to bus_deserialize_and_dump_unit_file_changes(). Otherwise we are hit by missing information (subsequent calls to unit_file_changes_add() to not add anything). Also prevent null pointer dereference in bus_deserialize_and_dump_unit_file_changes() by asserting. Fixes #3339
2016-06-09Revert "rules: allow users to access frame buffer devices" (#3333)Zbigniew Jędrzejewski-Szmek
This reverts commit 483d8bbb4c0190f419bf9fba57fb0feb1a56bea6.

I agree that this > should be reverted or at least hidden better. TBH, I think that privilege separation between processes running under the same UID is tenuous. Even with drm, in common setups any user process can ptrace the "current owner of the display" and call DROP_MASTER or do whatever. It *is* possible to prevent that, e.g. by disabling ptrace using yama.ptrace_scope, or selinux, and so on, but afaik this is not commonly done. E.g. all Fedora systems pull in elfutils-default-yama-scope.rpm through dependencies which sets yama.ptrace_scope=0. And even assuming that ptrace was disabled, it is trivial to modify files on disk, communicate through dbus, etc; there is just to many ways for a non-sandboxed process to interact maliciously with the display shell to close them all off. To achieve real protection, some sort of sandboxing must be implemented, and in that case there is no need to rely on access mode on the device files, since much more stringent measures have to be implemented anyway. The situation is similar for framebuffer devices. It is common to add framebuffer users to video group to allow them unlimited access to /dev/fb*. Using uaccess would be better solution in that case. Also, since there is no "current owner" limitation like in DRM, processes running under the same UID should be able to access /proc/<pid-of-display-server>/fd/* and gain access to the devices. Nevertheless, weston implements a suid wrapper to access the devices and then drop privileges, and this patch would make this daemon pointless. So if the weston developers feel that this change reduces security, I prefer to revert it. [1] https://lists.freedesktop.org/archives/wayland-devel/2016-May/029017.html
