This was the wrong fix to the problem, and it triggered a change in XKB
behavior: previously a button event would unlock a latched modifier, now it
doesn't anymore.
https://bugs.freedesktop.org/show_bug.cgi?id=73155
Note that the new behavior is is strictly spec compliant but we've had the
other behavior for a long time so we shouldn't break it.
The bug this patch originally fixed was a null-pointer dereference when
releasing button events on server shutdown. This was addressed by the commit
below, so the need for this patch has gone away anyway.

Whenever the master changes, push the locked modifier state to the attached
slave devices, then update the indicators. This way, when NumLock or CapsLock
are hit on any device, the LED will light up on all devices. Likewise, a new
keyboard attached to a master device will light up with the correct
indicators.
The indicators are handled per-keyboard, depending on the layout, i.e. if one
keyboard has grp_led:num set, the NumLock LED won't light up on that keyboard.

The main problem this patch addresses is that if a latch is put on
multi-level key with a Latch/Lock/Set, it is possible that after all
keys are released, still base modifiers are set, which typically will
make the keyboard unusable. To see how it happens (without the patch),
assume that key AltGr sets Mod5 when pressed by itself, and latches Mod3
when pressed together with Shift. Now press Shift, then AltGr and
release both keys in reverse order. Mod3 is now latched, and the
LatchMods filter remains active as the second filter. Now press AltGr;
Mod5 base modifier gets set, and the SetMods filter will become active
as the first filter. Release AltGr: First, the SetMods filter will set
clearMods to Mod5, then the LatchMods filter will overwrite clearMods
with Mod3. Result: the Mod5 base modifier will remain set. This
example becomes practically relevant for the revised German standard
layout (DIN 2137-1:2012-06).
Other changes implement the latch behaviour more accurately according to
the specification. For example, releasing a modifier latching key can
at the same time clear a locked modifier, promote another modifier that
is latched to locked, and latch a third modifier. Overall, what the
code does should be straightforward to compare what the XKB protocol
specification demands, see the table in section 6.3.
Finally, releasing a key no longer cancels a latch that has not become
pending yet. In my opinion, the specification is not clear; it speaks
of "operating" a key, which the patch effectivly interprets as "press"
rather than "press or release". From my experience, using the latter
interpretation makes latches on higher levels practically unusable. In
the example given above, one would have to release AltGr always before
Shift to get the Mod3-Latch. The practical relevance of latches on
higher levels is once more given by the revised German standard layout.

eventType is set for the type that triggered a XkbControlsNotify event.
Technically, SlowKeys is triggered by a timer which doesn't have a matching
core event type. So we used to use 0 here.
Practically, the timer is triggered by a key press + hold and cancelled when
the key is released before the timeout expires. So we might as well set
KeyPress (keycode) in the ControlsNotify to give clients a chance to differ
between timer-triggered SlowKeys and client-triggered ones.
This is a chance in behaviour, though I suspect with little impact.

For button release events, the current code picks the VCK. Because that has
a XKB struct, it thinks this is a PointerKeys event and proceeds to send the
release event through the XTest pointer. That has no effect in normal
operation as the button is never down and an attempt is silently discarded
(normal event processing continues with the VCP).
On server shutdown, the XTest device is already removed, leading to a
null-pointer derefernce when the device is checked for whether buttons are
down (XkbFakeDeviceButton → button_is_down(xtest pointer)).
The current state has only worked by accident, the right approach here is to
handle the VCP's event as such and not switch to the keyboard.

couldn't be found in an interpret as Any. So, an
XF86LogWindowTree+AnyOfOrNone(All) interp that triggered the PrWins
action would make every key without an action trigger PrWins if libX11
didn't yet know about the XF86LogWindowTree keysym. None too useful.
We only do this for XFree86 actions, as the current XKB dataset relies
on Any+AnyOfOrNone(All) -> SetMods for Ctrl in particular.

Due to an unfortunate sense inversion incident while switching from a
if (foo) { ... } to if (!foo) continue; style in f06a9d, we punished any
client who attempted to use XKB to restrict the MapNotify events they
wanted by sending them exactly the events they _didn't_ want, and
nothing else.
NewKeyboardNotifies (coming from a client setting the map with an XKB
request, when switching between master devices, etc) weren't affected,
but this would impact anyone using xmodmap-style core requests. Could
explain a fair bit.

We were using XIShouldNotify(client, device) as a test for whether or
not to send XKB map/state/etc changed events, which limits it to only
sending events for the current ClientPointer/ClientKeyboard for that
client. While this makes perfect sense for core events (e.g.
MappingNotify), XKB events carry a device ID, so are safe to send to all
clients for all devices.

Note that two variables are generally used for reallocation and
clearing of arrays: geom->sz_elems (reallocation) and geom->num_elems
(clearing). The interface of XkbGeomRealloc is deliberately kept
simple and it only accepts geom->sz_elems as argument, because that is
needed to determine whether the array needs to be resized. When the
array is cleared, we just assume that either geom->sz_elems and
geom->num_elems are synchronized to be equal or that unused elements
are cleared whenever geom->num_elems is set to be less than
geom->sz_elems without reallocation.

enabled_ctrls_changes nowhere near the usual event or config paths. So this
condition always evaluated to false and the memcpy would thus never been
hit. As a result, any modification to the XKB struct during
XkbUpdateDescActions was not reflected in the kbdfeed ctrls.
The flag that is set by XkbUpdateDescActions() if ctrls were changed are in
enabled_ctrls.
This mainly affected keyboard repeat control as XKB uses the kbdfeed ctrls,
not XKB's per_key_repeats, to determine if a key needs to be repeated. Thus,
adding a "repeat= False" to the XKB map of any action did not have any
effect.
Test case:
assign Mode_switch to any key that by default repeats, e.g. the menu key.
key <COMP> { [ Mode_switch ] };
Then modify the Mode_switch action to not repeat the key.
interpret Mode_switch+AnyOfOrNone(all) {
virtualModifier= AltGr;
useModMapMods=level1;
action= SetGroup(group=+1);
// Add this line
repeat= False;
};
Though the flags are correctly reflected in the description loaded in the
server, the change is not handed back to the kbdfeed struct and XKB will
trigger softrepeats of this key.
This patch also adds two explanatory comments and an extra check, as this
path may be hit before the CtrlProc for the kbdfeed struct is set.

This commit introduces an abstraction API for handling masked valuators. The
intent is that drivers just allocate a mask, set the data and pass the mask
to the server. The actual storage type of the mask is hidden from the
drivers.
The new calls for drivers are:
valuator_mask_new() /* to allocate a valuator mask */
valuator_mask_zero() /* to reset a mask to zero */
valuator_mask_set() /* to set a valuator value */
The new interface to the server is
xf86PostMotionEventM()
xf86PostButtonEventM()
xf86PostKeyboardEventM()
xf86PostProximityEventM()
all taking a mask instead of the valuator array.
The ValuatorMask is currently defined for MAX_VALUATORS fixed size due to
memory allocation restrictions in SIGIO handlers.
For easier review, a lot of the code still uses separate valuator arrays.
This will be fixed in a later patch.

commit 1432785839
xkb: release XTEST pointer buttons on physical releases. (#28808)
revealed a bug with the XTEST/PointerKeys interaction.
Events resulting from PointerKeys are injected into the event processing
stream, not appended to the event queue. The events generated for the fake
button press include a DeviceChangedEvent (DCE), a raw button event and the
button event itself. The DCE causes the master to switch classes to the
attached XTEST pointer device.
Once the fake button is processed, normal event processing continues with
events in the EQ. The master still contains the XTEST classes, causing some
events to be dropped if e.g. the number of valuators of the event in the
queue exceeds the XTEST device's number of valuators.
Example: the EQ contains the following events, processed one-by-one, left to
right.
[DCE (dev)][Btn down][Btn up][Motion][Motion][...]
^ XkbFakeDeviceButton injects [DCE (XTEST)][Btn up]
Thus the event sequence processed looks like this:
[DCE (dev)][Btn down][Btn up][DCE (XTEST)][Btn up][Motion][Motion][...]
The first DCE causes the master to switch to the device. The button up event
injects a DCE to the XTEST device, causing the following Motion events to be
processed with the master still being on XTEST classes.
This patch post-fixes the injected event sequence with a DCE to restore the
classes of the original slave device, resulting in an event sequence like
this:
[DCE (dev)][Btn down][Btn up][DCE (XTEST)][Btn up][DCE (dev)][Motion][Motion]
Note that this is a simplified description. The event sequence injected by
the PointerKeys code is injected for the master device only and the matching
slave device that caused the injection has already finished processing on
the slave. Furthermore, the injection happens as part of the the XKB layer,
before the unwrapping of the processInputProc takes us into the DIX where
the DCE is actually handled.
Bug reproducible with a device that reports more than 2 valuators. Simply
cause button releases on the device and wait for a "too many valuators"
warning message.

If a button release event is posted for the MD pointer, post a release event
through the matching XTEST device. This way, a client who posts a button
press through the XTEST extension cannot inadvertedly lock the button.
This behaviour is required for historical reasons, until server 1.7 the core
pointer would release a button press on physical events, regardless of the
XTEST state. Clients seem to rely on this behaviour, causing seemingly stuck
grabs.
The merged behaviour is kept for multiple keyboard PointerKey events, if two
physical keyboards hold the button down as a result of PointerKey actions,
the button is not released until the last keyboard releases the button.

Problem:
lockedPtrButtons keeps the state of the buttons locked by a PointerKeys button
press. Unconditionally clearing the bits may cause stuck buttons in this
sequence of events:
1. type Shift + NumLock to enable PointerKeys
2. type 0/Ins on keypad to emulate Button 1 press
→ button1 press event to client
3. press and release button 1 on physical mouse
→ button1 release event to client
Button 1 on the MD is now stuck and cannot be released.
Cause:
XKB PointerKeys button events are posted through the XTEST pointer device.
Once a press is generated, the XTEST device's button is down. The DIX merges
the button state of all attached SDs, hence the MD will have a button down
while the XTEST device has a button down.
PointerKey button events are only generated on the master device to avoid
duplicate events (see XkbFakeDeviceButton()). If the MD has the
lockedPtrButtons bit cleared by a release event on a physical device, no
such event is generated when a keyboard device triggers the PointerKey
ButtonRelease trigger. Since the event - if generated - is posted through
the XTEST pointer device, lack of a generated ButtonRelease event on the
XTEST pointer device means the button is never released, resulting in the
stuck button observed above.
Solution:
This patch merges the MD's lockedPtrButtons with the one of all attached
slave devices on release events. Thus, as long as one attached keyboard has
a lockedPtrButtons bit set, this bit is kept in the MD. Once a PointerKey
button is released on all keyboards, the matching release event is emulated
from the MD through the XTEST pointer device, thus also releasing the button
in the DIX.

Many references to the WindowTable array already had the corresponding
screen pointer handy, which meant they usually looked like
"WindowTable[pScreen->myNum]". Adding a field to ScreenRec instead of
keeping this information in a parallel array simplifies those
expressions, and eliminates a MAXSCREENS-sized array.
Since dix uses this data, a screen private entry isn't appropriate.
xf86-video-dummy currently uses WindowTable, so it needs to be updated
to reflect this change.

1bd7fd195d "XKB: Sanitise pointer actions"
61c508fa78 "XKB: Sanitise vmods in actions"
Strictly speaking, the structs used in the server are not part of the client
ABI. Practically, they are as we copy from the wire straight into the
structs. Changing the struct sizes breaks various wire/server conversions.
Even when the structs have the same size, some internal magic causes
conversions to fail. Visible by diffing the output files of:
setxkbmap -layout de; xkbcomp -xkb :0 busted.xkb
setxkbmap -layout de -print | xkbcomp -xkb - correct.xkb
Interestingly enough, busted.xkb is the working one although the output is
incorrect. Revert the four offending patches until the exact cause of this
breakage can be determined.
This patch restores functionality to Level3 modifiers.

There's devices (e.g. some barcode readers) that have axes but no buttons.
When such a device sends a motion event, the valuator and button class is
copied into the master pointer (i.e. removing the button class).
So we need a couple of extra sanity checks for the button class to exist.

isMaster is not enough as long as we differ between master pointers and
keyboard. With flexible device classes, the usual checks for whether a
master device is a pointer (currently check for ->button, ->valuators or
->key) do not work as an SD may post an event through a master and mess this
check up.
Example, a device with valuators but no buttons would remove the button
class from the VCP and thus result in the
IsPointerDevice(inputInfo.pointer) == FALSE.
This will become worse in the future when new device classes are introduced
that aren't provided in the current system (e.g. a switch class).
This patch replaces isMaster with "type", one of SLAVE, MASTER_POINTER and
MASTER_KEYBOARD. All checks for dev->isMaster are replaced with an
IsMaster(dev).
