Bug ID: 84817
Summary: Allowing a second user running on a WAYLAND_DISPLAY
requires the second user to have full permissions to
XDG_RUNTIME_DIR
Product: Wayland
Version: unspecified
Hardware: Other
OS: All
Status: NEW
Severity: normal
Priority: medium
Component: wayland
Assignee: [email protected]
Reporter: [email protected]
Theoretically, I should be able to give the second user just execute
permissions to the XDG_RUNTIME_DIR with setfacl, (with that the user can only
access files in the folder if the name is known, such as WAYLAND_DISPLAY)
However, right now, due to the creation of shared memory files in
XDG_RUNTIME_DIR, it fails to create the shm files, and many clients crash,
forcing the requirement to have full permissions to XDG_RUNTIME_DIR for the
user
It has been suggested that it should fall back to /dev/shm, and /tmp if it is
impossible to write the SHM files to XDG_RUNTIME_DIR on the irc.
