This refactors original KSU hooks to replace deep kernel function hooks with targeted hooks.
This backports KernelSU pr#1657 and having pr#2084 elements (32-bit sucompat).
It reduces the scope of kernel function interception and still maintains full fucntionality.
This commit is a squash of the following:
* fs/exec: do_execve: ksu_handle_execve_sucompat hook
* fs/exec: compat_do_execve: ksu_handle_execve_sucompat hook
fs/open: sys_faccessat: ksu_handle_faccessat hook

commit 8b188fba75195745026e11d408e4a7e94e01d701 upstream.
This reverts commit 37ef4c19b4c659926ce65a7ac709ceaefb211c40.
The touchpad present in the Dell Precision 7550 and 7750 laptops
reports a HID_DG_BUTTONTYPE of type MT_BUTTONTYPE_CLICKPAD. However,
the device is not a clickpad, it is a touchpad with physical buttons.
In order to fix this issue, a quirk for the device was introduced in
libinput [1] [2] to disable the INPUT_PROP_BUTTONPAD property:
[Precision 7x50 Touchpad]
MatchBus=i2c
MatchUdevType=touchpad
MatchDMIModalias=dmi:*svnDellInc.:pnPrecision7?50*
AttrInputPropDisable=INPUT_PROP_BUTTONPAD
However, because of the change introduced in 37ef4c19b4 ("Input: clear
BTN_RIGHT/MIDDLE on buttonpads") the BTN_RIGHT key bit is not mapped
anymore breaking the device right click button and making impossible to
workaround it in user space.
In order to avoid breakage on other present or future devices, revert
the patch causing the issue.

[ Upstream commit 37ef4c19b4c659926ce65a7ac709ceaefb211c40 ]
Buttonpads are expected to map the INPUT_PROP_BUTTONPAD property bit
and the BTN_LEFT key bit.
As explained in the specification, where a device has a button type
value of 0 (click-pad) or 1 (pressure-pad) there should not be
discrete buttons:
https://docs.microsoft.com/en-us/windows-hardware/design/component-guidelines/touchpad-windows-precision-touchpad-collection#device-capabilities-feature-report
However, some drivers map the BTN_RIGHT and/or BTN_MIDDLE key bits even
though the device is a buttonpad and therefore does not have those
buttons.
This behavior has forced userspace applications like libinput to
implement different workarounds and quirks to detect buttonpads and
offer to the user the right set of features and configuration options.
For more information:
https://gitlab.freedesktop.org/libinput/libinput/-/merge_requests/726
In order to avoid this issue clear the BTN_RIGHT and BTN_MIDDLE key
bits when the input device is register if the INPUT_PROP_BUTTONPAD
property bit is set.
Notice that this change will not affect udev because it does not check
for buttons. See systemd/src/udev/udev-builtin-input_id.c.

Currently, evdev stamps events with timestamps acquired in
evdev_events() However, this timestamping may not be accurate in terms
of measuring when the actual event happened.
Let's allow individual drivers specify timestamp in order to provide a
more accurate sense of time for the event. It is expected that drivers
will set the timestamp in their hard interrupt routine.

Commit 4369c64c79 ("Input: Send events one packet at a time")
significantly reduced amount of entropy input core was feeding to the rest
of the system, because only the very first event in the event block would
be used as source of entropy.
With this change we will be calling add_input_randomness() for every event
that is not filtered by the input core as a duplicate. In addition, all
EV_SYN events are ignored.

Add new function input_enable_softrepeat() that allows drivers to
initialize their own values for input_dev->rep[REP_DELAY] and
input_dev->rep[REP_PERIOD], but also use the software autorepeat
functionality from input.c.
For example, a HID driver could do:
static void xyz_input_configured(struct hid_device *hid,
struct hid_input *hidinput)
{
input_enable_softrepeat(hidinput->input, 400, 100);
}
static struct hid_driver xyz_driver = {
.input_configured = xyz_input_configured,

Instead of iterating over all bits in a bitmap and test them individually
let's siwtch to for_each_set_bit() which is more compact and is also
faster.

We want to allow drivers to call input_event() at any time after the
device got allocated. This means input_event() and input_register_device()
must be allowed to run in parallel.
The only conflicting calls in input_register_device() are init_timer() and
dev_set_name(). Both can safely be moved to device allocation and we're
good to go.

Apparently some users of managed input devices are confused whether
input_unregister_device() is needed when working with them. Clarify
this in the kernel doc for devm_input_allocate_device(): in most cases
there is no need to call neither input_unregister_device() nor
input_free_device() when working with managed devices.
Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
There is a demand from driver's writers to use managed devices framework
for their drivers. Unfortunately up to this moment input devices did not
provide support for managed devices and that lead to mixing two styles
of resource management which usually introduced more bugs, such as
manually unregistering input device but relying in devres to free
interrupt handler which (unless device is properly shut off) can cause
ISR to reference already freed memory.
This change introduces devm_input_allocate_device() that will allocate
managed instance of input device so that driver writers who prefer
using devm_* framework do not have to mix 2 styles.

Extend the amount of character devices, such as eventX, mouseX and jsX,
from a hard limit of 32 per input handler to about 1024 shared across

To be compatible with legacy installations input handlers will start
creating char devices with minors in their legacy range, however once
legacy range is exhausted they will start allocating minors from the
dynamic range 256-1024.

Merge Henrik's updates to multitouch code. Even though Jiri already
pulled them in I need to do it too since my changes to evdev using
dynamic major would clash with them.
On heavy event loads, such as a multitouch driver, the irqsoff latency
can be as high as 250 us. By accumulating a frame worth of data
before passing it on, the latency can be dramatically reduced. As a
side effect, the special EV_SYN handling can be removed, since the
frame is now atomic.
This patch adds the events() handler callback and uses it if it
exists. The latency is improved by 50 us even without the callback.

The events-per-packet estimate has so far been used by MT devices
only. This patch adjusts the packet buffer size to also accomodate the
KEY and MSC events. Keyboards normally send one or two keys at a
time. MT devices normally send a number of button keys along with the
MT information. The buffer size chosen here covers those cases, and
matches the default buffer size in evdev. Since the input estimate is
now preferred, remove the special input-mt estimate.
