73b4fc92f9 module: Move module's Kconfig items in kernel/module/
In init/Kconfig, the part dedicated to modules is quite large.

Move it into a dedicated Kconfig in kernel/module/

MODULES_TREE_LOOKUP was outside of the 'if MODULES', but as it is
only used when MODULES are set, move it in with everything else to
avoid confusion.

MODULE_SIG_FORMAT is left in init/Kconfig because this configuration
item is not used in kernel/modules/ but in kernel/ and can be
selected independently from CONFIG_MODULES. It is for instance
selected from security/integrity/ima/Kconfig.

87c482bdfa modules: Ensure natural alignment for .altinstructions and __bug_table sections
In the kernel image vmlinux.lds.S linker scripts the .altinstructions
and __bug_table sections are 4- or 8-byte aligned because they hold 32-
and/or 64-bit values.

Most architectures use altinstructions and BUG() or WARN() in modules as
well, but in the module linker script (module.lds.S) those sections are
currently missing. As consequence the linker will store their content
byte-aligned by default, which then can lead to unnecessary unaligned
memory accesses by the CPU when those tables are processed at runtime.

Usually unaligned memory accesses are unnoticed, because either the
hardware (as on x86 CPUs) or in-kernel exception handlers (e.g. on
parisc or sparc) emulate and fix them up at runtime. Nevertheless, such
unaligned accesses introduce a performance penalty and can even crash
the kernel if there is a bug in the unalignment exception handlers
(which happened once to me on the parisc architecture and which is why I
noticed that issue at all).

This patch fixes a non-critical issue and might be backported at any time.
It's trivial and shouldn't introduce any regression because it simply
tells the linker to use a different (8-byte alignment) for those
sections by default.

ae39e9ed96 module: Add support for default value for module async_probe
Add a module.async_probe kernel command line option that allows enabling
async probing for all modules. When this command line option is used,
there might still be some modules for which we want to explicitly force
synchronous probing, so extend <modulename>.async_probe to take an
optional bool input so that async probing can be disabled for a specific
module.

e69a66147d module: kallsyms: Ensure preemption in add_kallsyms() with PREEMPT_RT
The commit 08126db5ff ("module: kallsyms: Fix suspicious rcu usage")
under PREEMPT_RT=y, disabling preemption introduced an unbounded
latency since the loop is not fixed. This change caused a regression
since previously preemption was not disabled and we would dereference
RCU-protected pointers explicitly. That being said, these pointers
cannot change.

Before kallsyms-specific data is prepared/or set-up, we ensure that
the unformed module is known to be unique i.e. does not already exist
(see load_module()). Therefore, we can fix this by using the common and
more appropriate RCU flavour as this section of code can be safely
preempted.

f963ef1239 module: Fix "warning: variable 'exit' set but not used"
When CONFIG_MODULE_UNLOAD is not selected, 'exit' is
set but never used.

It is not possible to replace the #ifdef CONFIG_MODULE_UNLOAD by
IS_ENABLED(CONFIG_MODULE_UNLOAD) because mod->exit doesn't exist
when CONFIG_MODULE_UNLOAD is not selected.

And because of the rcu_read_lock_sched() section it is not easy
to regroup everything in a single #ifdef. Let's regroup partially
and add missing #ifdef to completely opt out the use of
'exit' when CONFIG_MODULE_UNLOAD is not selected.

35adf9a4e5 modules: Fix corruption of /proc/kallsyms
The commit 91fb02f315 ("module: Move kallsyms support into a separate
file") changed from using strlcpy() to using strscpy() which created a
buffer overflow. That happened because:
 1) an incorrect value was passed as the buffer length
 2) strscpy() (unlike strlcpy()) may copy beyond the length of the
    input string when copying word-by-word.
The assumption was that because it was already known that the strings
being copied would fit in the space available, it was not necessary
to correctly set the buffer length.  strscpy() breaks that assumption
because although it will not touch bytes beyond the given buffer length
it may write bytes beyond the input string length when writing
word-by-word.

The result of the buffer overflow is to corrupt the symbol type
information that follows. e.g.

 $ sudo cat -v /proc/kallsyms | grep '\^' | head
 ffffffffc0615000 ^@ rfcomm_session_get  [rfcomm]
 ffffffffc061c060 ^@ session_list        [rfcomm]
 ffffffffc06150d0 ^@ rfcomm_send_frame   [rfcomm]
 ffffffffc0615130 ^@ rfcomm_make_uih     [rfcomm]
 ffffffffc07ed58d ^@ bnep_exit   [bnep]
 ffffffffc07ec000 ^@ bnep_rx_control     [bnep]
 ffffffffc07ec1a0 ^@ bnep_session        [bnep]
 ffffffffc07e7000 ^@ input_leds_event    [input_leds]
 ffffffffc07e9000 ^@ input_leds_handler  [input_leds]
 ffffffffc07e7010 ^@ input_leds_disconnect       [input_leds]

Notably, the null bytes (represented above by ^@) can confuse tools.

Fix by correcting the buffer length.

aacb455dfe platform/x86: panasonic-laptop: filter out duplicate volume up/down/mute keypresses
On some Panasonic models the volume up/down/mute keypresses get
reported both through the Panasonic ACPI HKEY interface as well as
through the atkbd device.

Filter out the atkbd scan-codes for these to avoid reporting presses
twice.

Note normally we would leave the filtering of these to userspace by mapping
the scan-codes to KEY_UNKNOWN through /lib/udev/hwdb.d/60-keyboard.hwdb.
However in this case that would cause regressions since we were filtering
the Panasonic ACPI HKEY events before, so filter these in the kernel.

Change how acpi_video_handles_brightness_key_presses() determines if

vendor specific drivers/platform/x86 drivers filtering out their
brightness key-presses even though they are the only ones reporting

8698e3bab4 fanotify: refine the validation checks on non-dir inode mask
Commit ceaf69f8ea ("fanotify: do not allow setting dirent events in
mask of non-dir") added restrictions about setting dirent events in the
mask of a non-dir inode mark, which does not make any sense.

For backward compatibility, these restictions were added only to new
(v5.17+) APIs.

It also does not make any sense to set the flags FAN_EVENT_ON_CHILD or
FAN_ONDIR in the mask of a non-dir inode.  Add these flags to the
dir-only restriction of the new APIs as well.

Move the check of the dir-only flags for new APIs into the helper
fanotify_events_supported(), which is only called for FAN_MARK_ADD,
because there is no need to error on an attempt to remove the dir-only
flags from non-dir inode.

2390095113 tick/nohz: unexport __init-annotated tick_nohz_full_setup()
EXPORT_SYMBOL and __init is a bad combination because the .init.text
section is freed up after the initialization. Hence, modules cannot
use symbols annotated __init. The access to a freed symbol may end up
with kernel panic.

modpost used to detect it, but it had been broken for a decade.

Commit 28438794ab ("modpost: fix section mismatch check for exported
init/exit sections") fixed it so modpost started to warn it again, then
this showed up:

    MODPOST vmlinux.symvers
  WARNING: modpost: vmlinux.o(___ksymtab_gpl+tick_nohz_full_setup+0x0): Section mismatch in reference from the variable __ksymtab_tick_nohz_full_setup to the function .init.text:tick_nohz_full_setup()
  The symbol tick_nohz_full_setup is exported and annotated __init
  Fix this by removing the __init annotation of tick_nohz_full_setup or drop the export.

Drop the export because tick_nohz_full_setup() is only called from the
built-in code in kernel/sched/isolation.c.

037d430556 vhost-vdpa: call vhost_vdpa_cleanup during the release
Before commit 3d56987938 ("vhost-vdpa: introduce asid based IOTLB")
we call vhost_vdpa_iotlb_free() during the release to clean all regions
mapped in the iotlb.

That commit removed vhost_vdpa_iotlb_free() and added vhost_vdpa_cleanup()
to do some cleanup, including deleting all mappings, but we forgot to call
it in vhost_vdpa_release().

This causes that if an application does not remove all mappings explicitly
(or it crashes), the mappings remain in the iotlb and subsequent
applications may fail if they map the same addresses.

Calling vhost_vdpa_cleanup() also fixes a memory leak since we are not
freeing `v->vdev.vqs` during the release from the same commit.

Since vhost_vdpa_cleanup() calls vhost_dev_cleanup() we can remove its
call from vhost_vdpa_release().

e0c2ce8217 virtio_mmio: Restore guest page size on resume
Virtio devices might lose their state when the VMM is restarted
after a suspend to disk (hibernation) cycle. This means that the
guest page size register must be restored for the virtio_mmio legacy
interface, since otherwise the virtio queues are not functional.

This is particularly problematic for QEMU that currently still defaults
to using the legacy interface for virtio_mmio. Write the guest page
size register again in virtio_mmio_restore() to make legacy virtio_mmio
devices work correctly after hibernation.

ed7ac37fde virtio_mmio: Add missing PM calls to freeze/restore
Most virtio drivers provide freeze/restore callbacks to finish up
device usage before suspend and to reinitialize the virtio device after
resume. However, these callbacks are currently only called when using
virtio_pci. virtio_mmio does not have any PM ops defined.

This causes problems for example after suspend to disk (hibernation),
since the virtio devices might lose their state after the VMM is
restarted. Calling virtio_device_freeze()/restore() ensures that
the virtio devices are re-initialized correctly.

Fix this by implementing the dev_pm_ops for virtio_mmio,
similar to virtio_pci_common.

11a37eb668 caif_virtio: fix race between virtio_device_ready() and ndo_open()
We currently depend on probe() calling virtio_device_ready() -
which happens after netdev
registration. Since ndo_open() can be called immediately
after register_netdev, this means there exists a race between
ndo_open() and virtio_device_ready(): the driver may start to use the
device (e.g. TX) before DRIVER_OK which violates the spec.

Fix this by switching to use register_netdevice() and protect the
virtio_device_ready() with rtnl_lock() to make sure ndo_open() can
only be called after virtio_device_ready().
