Really I don't know what to comment here else. My analysis showed two independent issues, one is that seatd should have a declared group so that users of it could join it. This issues is not specific to greetd/greeter in any way. Any other greeting mechanism could fall short on this. And second, greeter today required conditional group to interact with seatd, or it could be any other group like input, usb, modem or else depending on user setup. Solutions are offered accordingly. Third issue, this bug I was asked to open. I don't understand, is it a sin to have multiple issues, or what is the problem here? > >> > >> seatd it self has to run as root. > Okay. > >> That TODO is from the initial commit, it is about cgroup file >> system mounting, and totally out of scope of this issue. > I didn't mean your code, I meant a suggestion from a reviewer > that you > haven't addressed yet (to my knowledge at least). done > > Cheers --=-=-= Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQIzBAEBCAAdFiEESPY5lma9A9l5HGLP6M7O0mLOBeIFAmLsvxMACgkQ6M7O0mLO BeI5lBAAioynCgDd0ltCYi631xZwj0FxEFYSfN+V7h8OeOejwEbz8gJ6N38hNLTC yeoz8LnGapDH3ysf49KsMHw7u0gXb3WKuUGUIrKtXTk7FKHBQ6iZ1W3R3IsGaVY+ nCLci4SsrocwTHWhPV9bCS+ysRR9VqNUdKBX+06VoQRxlzMwie/eVXFtqyKEgQ+v sWi8trAMgrU/J8kEAZcit9pBDwz3zTTMeQjljVqpO5k3RbzSl6sjtw1gNZA/aGEw 77DnZ7IUHwJw6xcmGO6w/dmOywAeaD/hW+Uuu3Z/zwlh62q79rMNbD57bGHE7zYb afUB5WKEZfpdiNw+JR4mLPaHFDPL7DTwBwxoHCPqCK53t7VkFKTdCNa67rsOsZsY IwjmjnwOYOhk3MOra+EwZOb51fEL+Oxu3497I5wGfPxabHvhnpKKJrzKM20lP3yo akgcxZf/6qQfebM2LFYdB+yeZ3NJX5lIkhcenlJvH7F47X4jD20gMYP4Uk9W1DzC NotVcUl0MRzMbVLSbZq7RJZhxnxrNOZeckoemDmojlhiL2KS32irVof7HF+J56NW axzvkhJJj8MHWArvMgrR24Qre2rQnFcxDA08tfpOQykY/uqBB3PZMRIVtSxwIoK7 hYBgM2ZU3Vx0NJV4N2YJ/oZC7VgmXbdRh0f1TZVml+RMiIXGIc0= =SiA5 -----END PGP SIGNATURE----- --=-=-=--

When seatd opening socket as root/seat, all members of seat would be able to communicate with it. Also socket could be opened with seat/seat for instance, but there is no specific point in doing=20 so. Will be one more unused system user around. Arch seems to follow similar way, root/seat is ok for socket. Also will signal that seatd is running as root. >> * 56699 - gnu: greetd-service-type: Add greeter-extra-groups >> =C2=A0 config field. >> With this change, if user wants to use seatd-service-type with >> greeter requiring seatd.sock, he can add "seat" group to >> greeter-extra-groups field. > Note that you still have a TODO on that patch.

Note that you still have a TODO on that patch. Cheers

While it is ok for greeters that do not talk to seatd, greeters talking to seatd lost access to seatd socket. As result, greeter (e.g. gtkgreet) requiring communication with seatd is failing to start, causing "black screen" behavior on active terminal (switching to the other non seatd related terminal is possible, for manual permissions adjustment as workaround). To address this issue, we need more flexible control over seatd user/group, which creates seatd.sock, and greeter user which connects to seatd.sock. Other distros (Arch for instance) introduced "seat" group. So user which wants to login on system controlled by seatd should be member of that group. However, not all greeters require that, so I decided to make more flexible. Propsed solutions consists of: * 56690 - gnu: seatd-service-type: Should use seat group. With this change, if seatd-service-type is present in the system configuration, "seat" group will be added, and seatd will run as root/seat. Group is configurable, but default is "seat". * 56699 - gnu: greetd-service-type: Add greeter-extra-groups config field. With this change, if user wants to use seatd-service-type with greeter requiring seatd.sock, he can add "seat" group to greeter-extra-groups field.
