Right now we only show the session menu button when verifying,
but we should also show it when verification is failed or we
can end up in situation where the session menu disappears during
an authentication retry.

This commit consolidates the styles of the various
message types into one 'login-dialog-message' style
and then adds additional styles on top to cover the
differences.
This allows us to give the message label an initial
style so that is padded properly before any messages
are displayed.

Right now, we rely on PAM to ask for the username if disable-user-list
is TRUE. This is suboptimal because it means we can't check if we
should show a session menu.
This commit changes disable-user-list==TRUE to ask for a username up
front, rather than have PAM do it.

This commit detects when a user inserts a smartcard,
and then initiates user verification using the gdm-smartcard
PAM service.
Likewise, if a user removes their smartcard, password verification
(or the user list depending on auth mode and configuration) are initiated
https://bugzilla.gnome.org/show_bug.cgi?id=683437
The duplication makes the function look a lot more complicated
than it actually is.
This commit moves the common code to a new _startService function.
https://bugzilla.gnome.org/show_bug.cgi?id=683437
Some pam modules prompt without expecting the user to type
an answer back (e.g. "Please swipe finger"). We need to
emit prompted in this case too, so the the dialog will get shown.
https://bugzilla.gnome.org/show_bug.cgi?id=683437
Currently, fingerprint authentication is always a secondary thing.
If a user wants to swipe their finger when the computer is asking
for a password, so be it.
This commit paves the way for making fingerprint auth optionally
be the main way to authenticate. Currently there's no way to enable
this, but in a future commit will honor
enable-password-authentication=false
in gsettings.
https://bugzilla.gnome.org/show_bug.cgi?id=683437
Right now, the primary way a user logs in is with
a password. They can also swipe their finger, if their
fingerprint is enrolled, but it's expected the fingerprint
auth service won't ask questions the user has to respond to
by typing. As such, we ignore questions that comes from
anything but the main auth service: gdm-password.
In the future, if a user inserts a smartcard, we'll want
to treat the gdm-smartcard service as the main auth service,
and let any questions from it get to the user.
This commit tries to prepare for that eventuality by storing
the name of the default auth service away in a _defaultService variable
before verification has begun, and then later checking incoming
queries against that service instead of checking against
string 'gdm-password' directly.
Of course, right now, _defaultService is always gdm-password.
https://bugzilla.gnome.org/show_bug.cgi?id=683437
This commit introduces a new BeginRequestType enum which gets
passed to the 'reset' signal to specify whether
a username should be provided to the begin() method and changes
the loginDialog to comply.
Currently, the signal only ever gets emitted with
AuthPrompt.BeginRequestType.PROVIDE_USERNAME
but that will change in the future when providing smartcard
support.
https://bugzilla.gnome.org/show_bug.cgi?id=683437
We currently emit "failed" any time the UserVerifier is reset,
and user verification didn't succeed prior.
A more conceptually clear time to emit "failed" would be if
the UserVerifier is reset and user verification failed prior,
and to emit "failed" if the user cancels unlock.
This commit restructures things to do that. Aside from being
more conceptually clear, it also lays the groundwork for us
to be able to reset the unlock screen without failing.
https://bugzilla.gnome.org/show_bug.cgi?id=683437
authPrompt.reset() currently only leaves the authPrompt in a
sane state if the user isn't verifying.
This commit makes sure to cancel verification if a reset happens
while verification is in process.
https://bugzilla.gnome.org/show_bug.cgi?id=683437
Swap out the implementation of SystemIndicator with a dummy,
and build the aggregate menu. At the same time, remove the
poweroff and login screen menus, as those were fake aggregate
menus beforehand.
We lose some flexibility as we lose session-mode-based menu
layout, but as each component of the aggregate menu is supposed
to be "smart" in response to updating itself when session
state changes, I believe it's better than a declarative model.
https://bugzilla.gnome.org/show_bug.cgi?id=705845
We can't silently replace the old behavior of separate status
icons into a new system. Replace SystemStatusButton with a new
SystemIndicator class which will allow for the flexibility we
need. For now, make it a subclass of Button so that it mostly
feels the same, but we'll soon be swapping it out with a dummy
implementation that the aggregate menu will use.
I think the code cleanup here is worth it.
https://bugzilla.gnome.org/show_bug.cgi?id=705845
onAskQuestion has this code:
if (this.verifyingUser)
this.cancelButton.show();
else
this.cancelButton.hide();
but onAskQuestion can only be called when this.verifyingUser is true.
Also, cancelButton is public, and it only ever otherwise gets hidden
from callers.
This commit drops mucking with cancelButton visibility, leaving it
entirely up to the callers to deal with.
https://bugzilla.gnome.org/show_bug.cgi?id=683437
If the first question asked to a user is from the
shell and not from the PAM service (i.e. Username: ),
then we'll save what the user types until PAM asks
a question and then try to send it to PAM.
This commit makes sure the preemptive answer can be used
before the PAM conversation gets started, and makes sure
to discard the preemptive answer if we're not expecting it.
https://bugzilla.gnome.org/show_bug.cgi?id=705370
Right now we have two booleans that specify when user verification
is happening and when it succeeded, respectively.
This commit consolidates them into one AuthPromptStatus enumeration.
This clean up will allow us to check for verification failure more
easily.
https://bugzilla.gnome.org/show_bug.cgi?id=683437
The only time we ever call _reset directly is when
detecting changes to disable-user-list. We can implicitly
trigger a reset for this case, just as easily by calling
this._authPrompt.reset()
This commit makes that change for consistency and to make
it easier to adjust the authprompt workflow later.
https://bugzilla.gnome.org/show_bug.cgi?id=683437
Right now the whole authPrompt spreads out if a PAM message
comes in that longer than the entry.
This commit changes it to wrap instead, by forcing the
auth prompt to be a fixed width (slightly bigger than
the entry width was sized to previously).
https://bugzilla.gnome.org/show_bug.cgi?id=705037
When a ShellUserVerifier is asked to verify a user at the login
screen it will transparently first try to reauthenticate the user
against an existing session and then fall back to logging a user
into a new session. The former is used for user switching.
It's useful to know which type of verification is happening, so
the next button can be made to say "Unlock" instead of "Sign In" when
a user is already signed in.
This commit exports a new "reauthenticating" property on the
ShellUserVerifier that the auth prompt checks when deciding which
label to use for its next button.
https://bugzilla.gnome.org/show_bug.cgi?id=704795
If there are no messages in the queue and a user starts to
type then we can safely hide the message label since the
user has probably already read it.
This fixes a weirdness where "Incorrect Password" messages stay
around, even as the user types in the new correct password.
https://bugzilla.gnome.org/show_bug.cgi?id=704817
There's quite a bit of duplicated code between the login dialog
and the unlock dialog dealing with the various signals from the
ShellUserVerifier.
This commit moves that duplicated code into the AuthPrompt.
https://bugzilla.gnome.org/show_bug.cgi?id=704707
Right now there is a lot of duplicated code between the unlock
dialog and the login dialog.
This commit moves the login dialog's auth prompt to a separate
class, so that it can (in a subsequent commit) be used by the
unlock dialog.
https://bugzilla.gnome.org/show_bug.cgi?id=702308
A bug got introduced when moving the login dialog away from modal
dialog, such that it listens for escape key presses in a mouse
event handler instead of a keyboard event handler.
This commit fixes that code to correctly listen for key-press-event
instead of button-press-event.
https://bugzilla.gnome.org/show_bug.cgi?id=702308
Right now if disable-user-list is true we show it briefly, just so
that we can fade it out to the user entry.
This commit avoids the fade in that case.
https://bugzilla.gnome.org/show_bug.cgi?id=704471
this._clearMessageQueue() is a noop when this.hasPendingMessages is
false so calling it in that case doesn't make sense.
This commit drops that call.
https://bugzilla.gnome.org/show_bug.cgi?id=704347
Now that we preallocate space for the prompt message there is
a lot of loose space between the entry and the buttons.
This commit helps tighten things up by getting rid
of the large top padding set above the login buttons.
https://bugzilla.gnome.org/show_bug.cgi?id=702308
commit ea02380c15 changed the login
dialog to not use ModalDialog anymore. There's still one lingering
setInitialKeyFocus method call in the source, which will cause an
exception to be thrown when users have their user list disabled.
This commit fixes that.
https://bugzilla.gnome.org/show_bug.cgi?id=703874
There are some issues with the existing session menu. First, it looks
kinda bad. It seems like it's hanging around there, but it doesn't really know
what to do with itself.
Second, when it expands down it requires that the buttons below move
down with it. This kind of movement is awkward and looks a bit weird.
Third, its current position makes the "dialog" tall and unwieldy when
you add things like messages for fingerprint readers or authentication errors.
This commit moves the session list to a menu behind a button to address
the above problems.
Based on a patch by Jasper St. Pierre.
