Subject: [PATCH] daemon: fix wayland detection when deciding to bypass
Xsession
At the moment if there's a session file with the same name in
both /usr/share/xsessions and /usr/share/wayland-sessions, GDM
will think the wayland is getting used when deciding whether or
not to bypass the /etc/gdm/Xsession script, even if wayland is
explicitly being ignored.
This commit fixes the check.

Subject: [PATCH] data: disable wayland for proprietary nvidia machines
At the moment GLX applications don't work well when the
proprietary nvidia driver is used with a wayland session.
For now, disable wayland on that hardware, and users who
want to opt in can just edit the udev rule.
(or add their own that overrides it)

Subject: [PATCH] data: disable wayland on certain hardware
We're having issues with wayland on passthrough to virt
setups and with the vendor nvidia driver on hybrid graphics
setups, so disable it in those cases.
Also disable it on server chips for performance reasons.

Subject: [PATCH] data: only disable wayland on passthrough virt setups
at the moment we disable wayland on all hybrid graphics setups,
but most hybrid graphics setups work fine.
The case we really care about is passthrough virt. in that case,
wayland is a bad idea because:
1) kernel crashes
2) mutter provides no way to disable one of the cards, and will
always use one as a secondary gpu
This commit forces xorg in passthrough setups so the user can use
an xorg.conf to turn one of the cards off.

This is a bit of a safety net in case any processes in the session are

Given not having users may make GDM to launch initial setup, that
allows to create new users (potentially with sudo capabilities), it's
better to make look_for_existing_users() to return its status and only
if it didn't fail continue the gdm execution.

From 781e865705b0c134271c9ec21655cd5d8ce37fec Mon Sep 17 00:00:00 2001

Subject: [PATCH] display: ask accountservice if there are users rather than
enumerate users
At the moment we ask accountsservice to give us the list of users just
to find out if there is a list of users.
That's rather inefficient and might be wrong for directory server users
that have never logged in before.
This commit changes gdm to ask accountsservice the question we really
want to know the answer to; whether or not there are users.

Subject: [PATCH] local-display-factory: Don't try to respawn displays on
shutdown
At the moment in the shutdown path we may try to respawn displays
that just got killed.
The respawning happens when things are half torn down leading to
crashes.
This commit makes sure we turn off the respawn logic in the shutdown
path.

Subject: [PATCH 1/3] manager: Don't leak session objects
The first is from create_user_session_for display. Most callers don't
check the return value, so it should just be void.
The user data associated with the session also isn't unlinked from the
display when the display is finishing up, preventing the display and
session object from getting freed.
This commit makes both changes.

Subject: [PATCH 1/4] manager: don't kill timed login session immediately after
it starts
At the moment GDM is misidentifying timed login sessions as if
they are automatic login sessions. That leads to their displays
getting killed sometimes shortly after log in.
This commit corrects the check, so that timed login sessions aren't
treated as autologin sessions.

From 3864af1ea06d2125c1b1f5afa6fc12caa833980a Mon Sep 17 00:00:00 2001

Subject: [PATCH] session-worker: Don't switch back VTs until session is fully
exited
There's a race condition on shutdown where the session worker is
switching VTs back to the initial VT at the same time as the session
exit is being processed.
This means that manager may try to start a login screen (because of
the VT switch) when autologin is enabled when there shouldn't be a
login screen.
This commit makes sure both the PostSession script, and session-exited
signal emission are complete before initiating the VT switch back
to the initial VT.

From 521ff70fe447558461dd38cdec62a7c0a5a74f7a Mon Sep 17 00:00:00 2001

Subject: [PATCH 1/3] session-worker: expose worker state enum to type system
We're going to need to access the worker state as a property on
the worker object.
This commit hooks it up to glib-mkenums so the requisite goo can
get generated

From 14656db42a6b4d4d48cf74127f3187dfe85607ec Mon Sep 17 00:00:00 2001

Subject: [PATCH] utils: add new gdm-disable-wayland binary
We currently disable wayland for cirrus by calling printf
from a udev rule. This works, but it's a little too open
coded to easily write SELinux policy for.
This commit introduces a new program, gdm-disable-wayland,
that does the same thing, but in a dedicated binary.
A future commit will change the udev rule to use the binary.
https://bugzilla.gnome.org/show_bug.cgi?id=796315
(cherry picked from commit 2dc57da31781dedfe374ce353b0f5fd6aa9da56f)

Subject: [PATCH 2/3] session: Don't leak remote greeter interface
XDMCP login screens get a "Remote Geeter Interface" exported over
the bus connection (so the login window can provide a Disconnect
button).
This interface is getting leaked when the session object is disposed,
leaving the bus connection itself undisposed, which causes an fd
leak.
This commit plugs the interface leak, and thus the fd leak.

Subject: [PATCH 2/3] session-worker: kill user sessions when stop gdm service
At the moment the session worker exits as soon as it gets SIGTERM.
That means it may fail to stop the user session (which only happens
in the orderly shutdown path).
This commit sets up a SIGTERM handler that integrates with and
quits the main loop after the session is started.
It still retains the _exit-on-SIGTERM behavior before the session
is started, to ensure a stuck pam module doesn't prevent the
process from dying.
Some small changes to commit by Ray Strode.
Closes #400

Subject: [PATCH 3/3] xdmcp-display-factory: Clear launch environment when done
with it
The XDMCP disply factory examines the sessions of its displays'
launch environments when the displays change status.
Unfortunately it leaks a reference to the launch environment when
doing that.
This commit fixes the reference leak which leads to an fd leak.

Subject: [PATCH 4/4] GdmManager: Don't perform timed login if session gets
started
At the moment it's possible for the login screen to initiate
a timed login operation shortly after a user successfully starts
their session.
GDM won't complete the timed login operation, since a session is
already running, but will erroneously overwrite the username
associated with the session, misattributing the users session
to the timed login user.
Later, attempts to log in as the timed user will instead unlock the
session for the other user, since that session is now associated
with the timed login user.
This commit refuses timed login requests on sessions that are
already running, so the username doesn't get corrupted.
CVE-2019-3825
Closes https://gitlab.gnome.org/GNOME/gdm/issues/460

If GDM gets shutdown we should make sure all sessions get shutdown too.
This is a bit of a safety net in case any processes in the session are
lingering after the orderly shutdown.

Subject: [PATCH 04/51] manager: make get_login_window_session_id fail if no
login screen
Right now we oddly succeed from get_login_window_session_id
if we can't find a login window.
None of the caller expect that, so fail instead.
