lightdm (0.9.2) which aims to be a xdm replacement seems to
fall into the same pitfalls like kdm and gdm recently. There is
a lot of uid 0 code creating and chown()ing files in user dirs such as
for ~/.dmrc and ~/.Xauthority. Probably more, depending on
how the permissions of cache and log directories are set up. For example
process_start() also creates and chown()s logfiles on users behalf.
There is also one thing that I dont understand about the lightdm
user itself and why pam sessions seem to be started for it inside
the greeter session code.
The xdmcp code seems to be OK so far, after a quick review.
Thanks for doing this review, this issue is now being tracked in the
LightDM issue tracker:
Not sure what you mean in your question about the PAM sessions. The
greeter object inside the daemon creates PAMSession objects which
attempt to be authenticated, then passes the successful one to the
session code which starts the PAM session. Might just be bad naming
causing confusion? (I've been meaning to split this into
PAMAuthentication and PAMSession objects).
