KVM: nVMX: Clear IDT vectoring on nested VM-Exit for double/triple fault

[ Upstream commit 9bd1f0efa859b61950d109b32ff8d529cc33a3ad ]

Clear the IDT vectoring field in vmcs12 on next VM-Exit due to a double
or triple fault.  Per the SDM, a VM-Exit isn't considered to occur during
event delivery if the exit is due to an intercepted double fault or a
triple fault.  Opportunistically move the default clearing (no event
"pending") into the helper so that it's more obvious that KVM does indeed
handle this case.

Note, the double fault case is worded rather wierdly in the SDM:

  The original event results in a double-fault exception that causes the
  VM exit directly.

Temporarily ignoring injected events, double faults can _only_ occur if
an exception occurs while attempting to deliver a different exception,
i.e. there's _always_ an original event.  And for injected double fault,
while there's no original event, injected events are never subject to
interception.

Presumably the SDM is calling out that a the vectoring info will be valid
if a different exit occurs after a double fault, e.g. if a #PF occurs and
is intercepted while vectoring #DF, then the vectoring info will show the
double fault.  In other words, the clause can simply be read as:

  The VM exit is caused by a double-fault exception.

PCI/ACPI: Allow D3 only if Root Port can signal and wake from D3

[ Upstream commit dff6139015dc68e93be3822a7bd406a1d138628b ]

acpi_pci_bridge_d3(dev) returns "true" if "dev" is a hotplug bridge that
can handle hotplug events while in D3.  Previously this meant either:

  - "dev" has a _PS0 or _PR0 method (acpi_pci_power_manageable()), or

  - The Root Port above "dev" has a _DSD with a "HotPlugSupportInD3"
    property with value 1.

This did not consider _PRW, which tells us about wakeup GPEs (ACPI v6.4,
sec 7.3.13).  Without a wakeup GPE, from an ACPI perspective the Root Port
has no way of generating wakeup signals, so hotplug events will be lost if
we use D3.

Similarly, it did not consider _S0W, which tells us the deepest D-state
from which a device can wake itself (sec 7.3.20).  If _S0W tells us the
device cannot wake from D3, hotplug events will again be lost if we use D3.

Some platforms, e.g., AMD Yellow Carp, supply "HotPlugSupportInD3" without
_PRW or with an _S0W that says the Root Port cannot wake from D3.  On those
platforms, we previously put bridges in D3hot, hotplug events were lost,
and hotplugged devices would not be recognized without manually rescanning.

Allow bridges to be put in D3 only if the Root Port can generate wakeup
GPEs (wakeup.flags.valid), it can wake from D3 (_S0W), AND it has the
"HotPlugSupportInD3" property.

Neither Windows 10 nor Windows 11 puts the bridge in D3 when the firmware
is configured this way, and this change aligns the handling of the
situation to be the same.

dma-direct: don't over-decrypt memory

The original x86 sev_alloc() only called set_memory_decrypted() on
memory returned by alloc_pages_node(), so the page order calculation
fell out of that logic. However, the common dma-direct code has several
potential allocators, not all of which are guaranteed to round up the
underlying allocation to a power-of-two size, so carrying over that
calculation for the encryption/decryption size was a mistake. Fix it by
rounding to a *number* of pages, rather than an order.

Until recently there was an even worse interaction with DMA_DIRECT_REMAP
where we could have ended up decrypting part of the next adjacent
vmalloc area, only averted by no architecture actually supporting both
configs at once. Don't ask how I found that one out...

net: dsa: restrict SMSC_LAN9303_I2C kconfig

Since kconfig 'select' does not follow dependency chains, if symbol KSA
selects KSB, then KSA should also depend on the same symbols that KSB

they are limited to VLAN_8021Q if the latter is enabled. This prevents

rxrpc: Fix decision on when to generate an IDLE ACK

[ Upstream commit 9a3dedcf18096e8f7f22b8777d78c4acfdea1651 ]

Fix the decision on when to generate an IDLE ACK by keeping a count of the
number of packets we've received, but not yet soft-ACK'd, and the number of

track of which DATA sequence numbers correspond to those points.

We then generate an ACK when either counter exceeds 2.  The counters are
both cleared when we transcribe the information into any sort of ACK packet
for transmission.  IDLE and DELAY ACKs are skipped if both counters are 0
(ie. no change).

the basis that most calls don't last long enough for it to ever expire.

rxrpc: Fix listen() setting the bar too high for the prealloc rings

[ Upstream commit 88e22159750b0d55793302eeed8ee603f5c1a95c ]

AF_RXRPC's listen() handler lets you set the backlog up to 32 (if you bump
up the sysctl), but whilst the preallocation circular buffers have 32 slots
in them, one of them has to be a dead slot because we're using CIRC_CNT().

This means that listen(rxrpc_sock, 32) will cause an oops when the socket
is closed because rxrpc_service_prealloc_one() allocated one too many calls
and rxrpc_discard_prealloc() won't then be able to get rid of them because
it'll think the ring is empty.  rxrpc_release_calls_on_socket() then tries
to abort them, but oopses because call->peer isn't yet set.

Fix this by setting the maximum backlog to RXRPC_BACKLOG_MAX - 1 to match
the ring capacity.

hwmon: (pmbus) Check PEC support before reading other registers

[ Upstream commit d1baf7a3a3177d46a7149858beddb88a9eca7a54 ]

Make sure that the support of PEC is determined before the read of other
registers. Otherwise the validation of PEC can trigger an error on the read
of STATUS_BYTE or STATUS_WORD registers.

The problematic scenario is the following. A device with enabled PEC
support is up and running and a kernel driver is loaded.
Then the driver is unloaded (or device unbound), the HW device
is reconfigured externally (e.g. by i2cset) to advertise itself as not
supporting PEC. Without the move of the code, at the second load of
the driver (or bind) the STATUS_BYTE or STATUS_WORD register is always
read with PEC enabled, which is likely to cause a read error resulting
with fail of a driver load (or bind).

NFC: hci: fix sleep in atomic context bugs in nfc_hci_hcp_message_tx

[ Upstream commit b413b0cb008646e9f24ce5253cb3cf7ee217aff6 ]

There are sleep in atomic context bugs when the request to secure
element of st21nfca is timeout. The root cause is that kzalloc and
alloc_skb with GFP_KERNEL parameter and mutex_lock are called in
st21nfca_se_wt_timeout which is a timer handler. The call tree shows
the execution paths that could lead to bugs:

   (Interrupt context)
st21nfca_se_wt_timeout
  nfc_hci_send_event
    nfc_hci_hcp_message_tx
      kzalloc(..., GFP_KERNEL) //may sleep
      alloc_skb(..., GFP_KERNEL) //may sleep
      mutex_lock() //may sleep

This patch moves the operations that may sleep into a work item.
The work item will run in another kernel thread which is in
process context to execute the bottom half of the interrupt.
So it could prevent atomic context from sleeping.

bfq: Relax waker detection for shared queues

[ Upstream commit f950667356ce90a41b446b726d4595a10cb65415 ]

Currently we look for waker only if current queue has no requests. This
makes sense for bfq queues with a single process however for shared
queues when there is a larger number of processes the condition that
queue has no requests is difficult to meet because often at least one
process has some request in flight although all the others are waiting
for the waker to do the work and this harms throughput. Relax the "no
queued request for bfq queue" condition to "the current task has no
queued requests yet". For this, we also need to start tracking number of
requests in flight for each task.

This patch (together with the following one) restores the performance
for dbench with 128 clients that regressed with commit c65e6fd460b4
("bfq: Do not let waker requests skip proper accounting") because
this commit makes requests of wakers properly enter BFQ queues and thus
these queues become ineligible for the old waker detection logic.
Dbench results:

         Vanilla 5.18-rc3        5.18-rc3 + revert      5.18-rc3 patched

drm/i915: Fix CFI violation with show_dynamic_id()

[ Upstream commit 58606220a2f1407a7516c547f09a1ba7b4350a73 ]

When an attribute group is created with sysfs_create_group(), the
->sysfs_ops() callback is set to kobj_sysfs_ops, which sets the ->show()
callback to kobj_attr_show(). kobj_attr_show() uses container_of() to
get the ->show() callback from the attribute it was passed, meaning the
->show() callback needs to be the same type as the ->show() callback in
'struct kobj_attribute'.

However, show_dynamic_id() has the type of the ->show() callback in
'struct device_attribute', which causes a CFI violation when opening the
'id' sysfs node under drm/card0/metrics. This happens to work because
the layout of 'struct kobj_attribute' and 'struct device_attribute' are
the same, so the container_of() cast happens to allow the ->show()
callback to still work.

Change the type of show_dynamic_id() to match the ->show() callback in
'struct kobj_attributes' and update the type of sysfs_metric_id to
match, which resolves the CFI violation.

drm/msm/dpu: handle pm_runtime_get_sync() errors in bind path

[ Upstream commit 64b22a0da12adb571c01edd671ee43634ebd7e41 ]

If there are errors while trying to enable the pm in the
bind path, it will lead to unclocked access of hw revision
register thereby crashing the device.

This will not address why the pm_runtime_get_sync() fails
but at the very least we should be able to prevent the
crash by handling the error and bailing out earlier.

drm/msm: don't free the IRQ if it was not requested

[ Upstream commit 577e2a9dfc8fba7938aaf75db63fae7e328cc3cb ]

As msm_drm_uninit() is called from the msm_drm_init() error path,
additional care should be necessary as not to call the free_irq() for
the IRQ that was not requested before (because an error occured earlier

kselftest/arm64: bti: force static linking

[ Upstream commit d7a49291d786b4400996afe3afcc3ef5eeb6f0ef ]

The "bti" selftests are built with -nostdlib, which apparently
automatically creates a statically linked binary, which is what we want
and need for BTI (to avoid interactions with the dynamic linker).

However this is not true when building a PIE binary, which some
toolchains (Ubuntu) configure as the default.
When compiling btitest with such a toolchain, it will create a
dynamically linked binary, which will probably fail some tests, as the
dynamic linker might not support BTI:
===================
TAP version 13
1..18
not ok 1 nohint_func/call_using_br_x0
not ok 2 nohint_func/call_using_br_x16
not ok 3 nohint_func/call_using_blr
....
===================

To make sure we create static binaries, add an explicit -static on the
linker command line. This forces static linking even if the toolchain
defaults to PIE builds, and fixes btitest runs on BTI enabled machines.

The math emulation support code is intended for 68020 and higher, and
uses several instructions or instruction modes not available on coldfire

Originally, the dependency of M68KFPU_EMU on MMU was fine, as MMU

without MMU (which are not yet supported by Linux, though).

scripts/faddr2line: Fix overlapping text section failures

[ Upstream commit 1d1a0e7c5100d332583e20b40aa8c0a8ed3d7849 ]

There have been some recent reports of faddr2line failures:

  $ scripts/faddr2line sound/soundcore.ko sound_devnode+0x5/0x35
  bad symbol size: base: 0x0000000000000000 end: 0x0000000000000000

  bad symbol size: base: 0x0000000000005fe0 end: 0x0000000000005fe0

The problem is that faddr2line is based on 'nm', which has a major
limitation: it doesn't know how to distinguish between different text
sections.  So if an offset exists in multiple text sections in the
object, it may fail.

Rewrite faddr2line to be section-aware, by basing it on readelf.

2: arvif->is_started

we can make sure the vdev is present.

Also use ar->conf_mutex to synchronize vdev delete and mgmt. TX.

a skid from the time IBS interrupt gets triggered to the time the
interrupt is presented to the core. Meanwhile processor would have
moved ahead and thus IbsOpRip will be inconsistent with rsp and rbp
recorded as part of the interrupt regs. This causes issues while
unwinding stack using the ORC unwinder as it needs consistent rip,
rsp and rbp. Fix this by using rip from interrupt regs instead of
IbsOpRip for stack unwinding.
