The commit 08126db5 ("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. Reported-by:

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. Reported-by:

The commit 91fb02f3 ("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. Fixes: 91fb02f3 ("module: Move kallsyms support into a separate file") Signed-off-by:

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.

Commit ceaf69f8 ("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.

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 28438794 ("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.

Before commit 3d569879 ("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().

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. Signed-off-by:

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.

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().
