3e6b0bb22a HID: logitech-hidpp: Stop IO before calling hid_connect()
hid_connect() will call hid_pidff_init() which does
hid_device_io_start() leading to an "io already started" warning.

To fix this call hid_device_io_stop() before calling hid_connect(),
stopping IO means that connect events may be lost while hid_connect()
runs, re-enable IO and move the hidpp_connect_event() work queuing
after the hid_connect().

Note re-enabling IO is also necessary for the g920_get_config()
call later during hidpp_probe().

f3c4ee7166 HID: logitech-hidpp: Drop delayed_work_cb()
Drop delayed_work_cb() instead make hidpp_connect_event() the workqueue
function itself.

Besides resulting in a small cleanup this will hopefully also make
it clearer that going forward hidpp_connect_event() should only
be run from a workqueue and not be directly invoked.

680ee411a9 HID: logitech-hidpp: Fix connect event race
There is a connect event race in hidpp_probe() in these 2 lines:

	connected = hidpp_root_get_protocol_version(hidpp) == 0;
	atomic_set(&hidpp->connected, connected);

Specifically the following can happen:

1. This line from hidpp_probe() is executed:
	connected = hidpp_root_get_protocol_version(hidpp) == 0;
   and sets connected to false;

2. A connect-event packet is received and does:
	atomic_set(&hidpp->connected, true);

3. The next line from hidpp_probe() is executed:
	atomic_set(&hidpp->connected, connected);
   and sets the atomic_t back to 0 again.

4. hidpp_connect_event() runs and sees the connected device
   as disconnected because of this.

To fix this make hidpp_connect_event() query the connection status
of the device itself instead of having it rely on possibly stale
data cached in struct hidpp_device.

8954dac18c HID: logitech-hidpp: Move hidpp_overwrite_name() to before connect check
Move the hidpp_overwrite_name() call to before the connect check, this
puts it at the same place in the probe() order as hidpp_serial_init()
which seems more logical. This should not make a difference since this
is in the non-unifying path and only unifying devices can be probed
in non-connected state.

This is a preparation patch for moving all connected state handling
to hidpp_connect_event().

Doing this before the connect check requires dropping the protocol
version check since protocol_major is not set yet now. Instead
this relies on hidpp_root_get_feature(HIDPP_PAGE_GET_DEVICE_NAME_TYPE)
failing on older devices, just like how hidpp_get_serial() relies on
hidpp_root_get_feature(HIDPP_PAGE_DEVICE_INFORMATION) failing on older
devices. So this again makes the code more consistent.

Also stop printing an error on failure now, since with the proto
version check gone failures are expected to happen on older devices.

a3643036d7 HID: logitech-hidpp: Remove wtp_get_config() call from probe()
For WTP devices which start disconnected (paired with the unifying
receiver, but not connected atm) hidpp_connect_event() takes care
of calling wtp_get_config() when the device later connects.

There is no need to have a separate code path for WTP devices which
are connected at probe() time, these can use the same code-path since
probe() will queue hidpp_connect_event() for those at probe time.

Drop the unnecessary wtp_get_config() call from probe().

55bf70362f HID: logitech-hidpp: Revert "Don't restart communication if not necessary"
Commit 91cf9a98ae ("HID: logitech-hidpp: make .probe usbhid capable")
makes hidpp_probe() first call hid_hw_start(hdev, 0) to allow IO
without connecting any hid subdrivers (hid-input, hidraw).

This is done to allow to retrieve the device's name and serial number
and store these in hdev->name and hdev->uniq.

Then later on IO was stopped and started again with hid_hw_start(hdev,
HID_CONNECT_DEFAULT) connecting hid-input and hidraw after the name
and serial number have been setup.

Commit 498ba20690 ("HID: logitech-hidpp: Don't restart communication
if not necessary") changed the probe() code to only do the start with
a 0 connect-mask + restart later for unifying devices.

But for non unifying devices hdev->name and hdev->uniq are updated too.
So this change re-introduces the problem for which the start with
a 0 connect-mask + restart later behavior was introduced.

The previous patch in this series changes the unifying path to instead of
restarting IO only call hid_connect() later. This avoids possible issues
with restarting IO seen on non unifying devices.

Revert the change to limit the restart behavior to unifying devices to
fix hdev->name changing after userspace facing devices have already been
registered.

11ca0322a4 HID: logitech-hidpp: Don't restart IO, instead defer hid_connect() only
Restarting IO causes 2 problems:

1. Some devices do not like IO being restarted this was addressed in
   commit 498ba20690 ("HID: logitech-hidpp: Don't restart communication
   if not necessary"), but that change has issues of its own and needs to
   be reverted.

2. Restarting IO and specifically calling hid_device_io_stop() causes
   received packets to be missed, which may cause connect-events to
   get missed.

Restarting IO was introduced in commit 91cf9a98ae ("HID: logitech-hidpp:
make .probe usbhid capable") to allow to retrieve the device's name and
serial number and store these in hdev->name and hdev->uniq before
connecting any hid subdrivers (hid-input, hidraw) exporting this info
to userspace.

But this does not require restarting IO, this merely requires deferring
calling hid_connect(). Calling hid_hw_start() with a connect-mask of
0 makes it skip calling hid_connect(), so hidpp_probe() can simply call
hid_connect() later without needing to restart IO.

Remove the stop + restart of IO and instead just call hid_connect() later
to avoid the issues caused by restarting IO.

Now that IO is no longer stopped, hid_hw_close() must be called at the end
of probe() to balance the hid_hw_open() done at the beginning probe().

The same approach is chosen by 'struct usb_driver' and other subsystems.

2f2bd7cbd1 hid: lenovo: Resend all settings on reset_resume for compact keyboards
The USB Compact Keyboard variant requires a reset_resume function to
restore keyboard configuration after a suspend in some situations. Move
configuration normally done on probe to lenovo_features_set_cptkbd(), then
recycle this for use on reset_resume.

Without, the keyboard and driver would end up in an inconsistent state,
breaking middle-button scrolling amongst other problems, and twiddling
sysfs values wouldn't help as the middle-button mode won't be set until
the driver is reloaded.

Tested on a USB and Bluetooth Thinkpad Compact Keyboard.

dc3115e6c5 hid: cp2112: Fix IRQ shutdown stopping polling for all IRQs on chip
Previously cp2112_gpio_irq_shutdown() always cancelled the
gpio_poll_worker, even if other IRQs were still active, and did not set
the gpio_poll flag to false. This resulted in any call to _shutdown()
resulting in interrupts no longer functioning on the chip until a
_remove() occurred (a.e. the cp2112 is unplugged or system rebooted).

Only cancel polling if all IRQs are disabled/masked, and correctly set
the gpio_poll flag, allowing polling to restart when an interrupt is
next enabled.

  Closing of an event channel in the Linux kernel can result in a

  The closing of an event channel is e.g. triggered by removal of a

  console messages to be issued on the other side quite often, the
  chance of triggering the deadlock is not negligible"

01bbafc63b KEYS: trusted: Remove redundant static calls usage
Static calls invocations aren't well supported from module __init and
__exit functions. Especially the static call from cleanup_trusted() led
to a crash on x86 kernel with CONFIG_DEBUG_VIRTUAL=y.

However, the usage of static call invocations for trusted_key_init()
and trusted_key_exit() don't add any value from either a performance or
security perspective. Hence switch to use indirect function calls instead.

Note here that although it will fix the current crash report, ultimately
the static call infrastructure should be fixed to either support its
future usage from module __init and __exit functions or not.

42999c9046 hv/hv_kvp_daemon:Support for keyfile based connection profile
Ifcfg config file support in NetworkManger is deprecated. This patch
provides support for the new keyfile config format for connection
profiles in NetworkManager. The patch modifies the hv_kvp_daemon code
to generate the new network configuration in keyfile
format(.ini-style format) along with a ifcfg format configuration.
The ifcfg format configuration is also retained to support easy
backward compatibility for distro vendors. These configurations are
stored in temp files which are further translated using the
hv_set_ifconfig.sh script. This script is implemented by individual
distros based on the network management commands supported.
For example, RHEL's implementation could be found here:
https://gitlab.com/redhat/centos-stream/src/hyperv-daemons/-/blob/c9s/hv_set_ifconfig.sh
Debian's implementation could be found here:
https://github.com/endlessm/linux/blob/master/debian/cloud-tools/hv_set_ifconfig

The next part of this support is to let the Distro vendors consume
these modified implementations to the new configuration format.

Tested-on: Rhel9(Hyper-V, Azure)(nm and ifcfg files verified)

054c22bd78 printk: flush consoles before checking progress
Commit 9e70a5e109 ("printk: Add per-console suspended state")
removed console lock usage during resume and replaced it with
the clearly defined console_list_lock and srcu mechanisms.

However, the console lock usage had an important side-effect
of flushing the consoles. After its removal, consoles were no
longer flushed before checking their progress.

Add the console_lock/console_unlock dance to the beginning
of __pr_flush() to actually flush the consoles before checking
their progress. Also add comments to clarify this additional
usage of the console lock.

Note that console_unlock() does not guarantee flushing all messages
since the commit dbdda842fe ("printk: Add console owner and waiter
logic to load balance console writes").

87797fad6c xen/events: replace evtchn_rwlock with RCU
In unprivileged Xen guests event handling can cause a deadlock with
Xen console handling. The evtchn_rwlock and the hvc_lock are taken in
opposite sequence in __hvc_poll() and in Xen console IRQ handling.
Normally this is no problem, as the evtchn_rwlock is taken as a reader
in both paths, but as soon as an event channel is being closed, the
lock will be taken as a writer, which will cause read_lock() to block:

CPU0                     CPU1                CPU2
(IRQ handling)           (__hvc_poll())      (closing event channel)

read_lock(evtchn_rwlock)
                         spin_lock(hvc_lock)
                                             write_lock(evtchn_rwlock)
                                                 [blocks]
spin_lock(hvc_lock)
    [blocks]
                        read_lock(evtchn_rwlock)
                            [blocks due to writer waiting,
                             and not in_interrupt()]

This issue can be avoided by replacing evtchn_rwlock with RCU in
xen_free_irq(). Note that RCU is used only to delay freeing of the
irq_info memory. There is no RCU based dereferencing or replacement of
pointers involved.

In order to avoid potential races between removing the irq_info
reference and handling of interrupts, set the irq_info pointer to NULL
only when freeing its memory. The IRQ itself must be freed at that
time, too, as otherwise the same IRQ number could be allocated again
before handling of the old instance would have been finished.

This is XSA-441 / CVE-2023-34324.

914988e099 parisc: Restore __ldcw_align for PA-RISC 2.0 processors
Back in 2005, Kyle McMartin removed the 16-byte alignment for
ldcw semaphores on PA 2.0 machines (CONFIG_PA20). This broke
spinlocks on pre PA8800 processors. The main symptom was random
faults in mmap'd memory (e.g., gcc compilations, etc).

Unfortunately, the errata for this ldcw change is lost.

The issue is the 16-byte alignment required for ldcw semaphore
instructions can only be reduced to natural alignment when the
ldcw operation can be handled coherently in cache. Only PA8800
and PA8900 processors actually support doing the operation in
cache.

Aligning the spinlock dynamically adds two integer instructions
to each spinlock.

Tested on rp3440, c8000 and a500.
