Disk failed to rediscover after chip reset error injection. The chip reset
happens at the time when a PLOGI is being sent. This causes a flag to be

Currently IOCBs are allowed to push through while chip reset could be in
progress. During chip reset the outstanding_cmds array is cleared
twice. Once when any command on this array is returned as failed and
secondly when the array is initialize to zero. If a command is inserted on
to the array between these intervals, then the command will be lost. Check
for chip reset before sending IOCB.

As of commit d8649fc1c5e4 ("scsi: libsas: Do discovery on empty PHY to
update PHY info"), do discovery will send a new SMP_DISCOVER and update
phy->phy_change_count. We found that if the disk is reconnected and phy
change_count changes at this time, the disk scanning process will not be
triggered.
Therefore, call sas_set_ex_phy() to update the PHY info with the results of
the last query. And because the previous phy info will be used when calling
sas_unregister_devs_sas_addr(), sas_unregister_devs_sas_addr() should be
called before sas_set_ex_phy().

For a physical PCI device that is passed through to a Hyper-V guest VM,
current code specifies the VMBus ring buffer size as 4 pages. But this
is an inappropriate dependency, since the amount of ring buffer space
needed is unrelated to PAGE_SIZE. For example, on x86 the ring buffer
size ends up as 16 Kbytes, while on ARM64 with 64 Kbyte pages, the ring
size bloats to 256 Kbytes. The ring buffer for PCI pass-thru devices
is used for only a few messages during device setup and removal, so any
space above a few Kbytes is wasted.
Fix this by declaring the ring buffer size to be a fixed 16 Kbytes.
Furthermore, use the VMBUS_RING_SIZE() macro so that the ring buffer
header is properly accounted for, and so the size is rounded up to a
page boundary, using the page size for which the kernel is built. While
w/64 Kbyte pages this results in a 64 Kbyte ring buffer header plus a
64 Kbyte ring buffer, that's the smallest possible with that page size.
It's still 128 Kbytes better than the current code.

The commit message in commit fc9a77040b04 ("PCI: designware-ep: Configure
Resizable BAR cap to advertise the smallest size") claims that it modifies
the Resizable BAR capability to only advertise support for 1 MB size BARs.
However, the commit writes all zeroes to PCI_REBAR_CAP (the register which
contains the possible BAR sizes that a BAR be resized to).
According to the spec, it is illegal to not have a bit set in
PCI_REBAR_CAP, and 1 MB is the smallest size allowed.
Set bit 4 in PCI_REBAR_CAP, so that we actually advertise support for a
1 MB BAR size.
Before:
Capabilities: [2e8 v1] Physical Resizable BAR
BAR 0: current size: 1MB
BAR 1: current size: 1MB
BAR 2: current size: 1MB
BAR 3: current size: 1MB

After:

There can be platforms that do not use/have 32-bit DMA addresses.
The current implementation of 32-bit IOVA allocation can fail for
such platforms, eventually leading to the probe failure.
Try to allocate a 32-bit msi_data. If this allocation fails,
attempt a 64-bit address allocation. Please note that if the
64-bit MSI address is allocated, then the EPs supporting 32-bit
MSI address only will not work.

Qcom SoCs making use of ARM SMMU require BDF to SID translation table in
the driver to properly map the SID for the PCIe devices based on their BDF
identifier. This is currently achieved with the help of
qcom_pcie_config_sid_1_9_0() function for SoCs supporting the 1_9_0 config.
But With newer Qcom SoCs starting from SM8450, BDF to SID translation is
set to bypass mode by default in hardware. Due to this, the translation
table that is set in the qcom_pcie_config_sid_1_9_0() is essentially
unused and the default SID is used for all endpoints in SoCs starting from
SM8450.
This is a security concern and also warrants swapping the DeviceID in DT
while using the GIC ITS to handle MSIs from endpoints. The swapping is
currently done like below in DT when using GIC ITS:
/*
* MSIs for BDF (1:0.0) only works with Device ID 0x5980.
* Hence, the IDs are swapped.
*/
msi-map = <0x0 &gic_its 0x5981 0x1>,
<0x100 &gic_its 0x5980 0x1>;
Here, swapping of the DeviceIDs ensure that the endpoint with BDF (1:0.0)
gets the DeviceID 0x5980 which is associated with the default SID as per
the iommu mapping in DT. So MSIs were delivered with IDs swapped so far.
But this also means the Root Port (0:0.0) won't receive any MSIs (for PME,
AER etc...)
So let's fix these issues by clearing the BDF to SID bypass mode for all
SoCs making use of the 1_9_0 config. This allows the PCIe devices to use
the correct SID, thus avoiding the DeviceID swapping hack in DT and also
achieving the isolation between devices.
Fixes: 4c9398822106 ("PCI: qcom: Add support for configuring BDF to SID mapping for SM8250")

Add timeout to cm_destroy_id, so that userspace can trigger any data
collection that would help in analyzing the cause of delay in destroying

New noinline function helps dtrace/ebpf programs to hook on to it.
Existing functionality isn't changed except triggering a probe-able new
function at every timeout interval.
We have seen cases where CM messages stuck with MAD layer (either due to
software bug or faulty HCA), leading to cm_id getting stuck in the

Since commit 43a7206b0963 ("driver core: class: make class_register() take
a const *"), the driver core allows for struct class to be in read-only
memory, so move the pcmcia_socket_class structure to be declared at build
time placing it into read-only memory, instead of having to be dynamically
allocated at boot time.

Pull firewire fix from Takashi Sakamoto:
"A fix to suppress a warning about unreleased IRQ for 1394 OHCI
hardware when disabling MSI.
In Linux kernel v6.5, a PCI driver for 1394 OHCI hardware was
optimized into the managed device resources. Edmund Raile points out
that the change brings the warning about unreleased IRQ at the call of
pci_disable_msi(), since the API expects that the relevant IRQ has
already been released in advance.
As long as the API is called in .remove callback of PCI device
operation, it is prohibited to maintain the IRQ as the part of managed
device resource. As a workaround, the IRQ is explicitly released at
.remove callback, before the call of pci_disable_msi().
pci_disable_msi() is legacy API nowadays in PCI MSI implementation. I
have a plan to replace it with the modern API in the development for
the future version of Linux kernel. So at present I keep them as is"

KVM GUEST_MEMFD fixes for 6.8:
- Make KVM_MEM_GUEST_MEMFD mutually exclusive with KVM_MEM_READONLY to
avoid creating ABI that KVM can't sanely support.
- Update documentation for KVM_SW_PROTECTED_VM to make it abundantly
clear that such VMs are purely a development and testing vehicle, and
come with zero guarantees.
- Limit KVM_SW_PROTECTED_VM guests to the TDP MMU, as the long term plan
is to support confidential VMs with deterministic private memory (SNP
and TDX) only in the TDP MMU.
- Fix a bug in a GUEST_MEMFD negative test that resulted in false passes
when verifying that KVM_MEM_GUEST_MEMFD memslots can't be dirty logged.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

Currently, the EFI stub invokes the EFI memory attributes protocol to
strip any NX restrictions from the entire loaded kernel, resulting in
all code and data being mapped read-write-execute.
The point of the EFI memory attributes protocol is to remove the need
for all memory allocations to be mapped with both write and execute
permissions by default, and make it the OS loader's responsibility to
transition data mappings to code mappings where appropriate.
Even though the UEFI specification does not appear to leave room for
denying memory attribute changes based on security policy, let's be
cautious and avoid relying on the ability to create read-write-execute
mappings. This is trivially achievable, given that the amount of kernel
code executing via the firmware's 1:1 mapping is rather small and
limited to the .head.text region. So let's drop the NX restrictions only
on that subregion, but not before remapping it as read-only first.

To allow event log info access after boot, EFI boot stub extracts
the event log information and installs it in an EFI configuration
table. Currently, EFI boot stub only supports installation of event
log only for TPM 1.2 and TPM 2.0 protocols. Extend the same support
for CC protocol. Since CC platform also uses TCG2 format, reuse TPM2
support code as much as possible.

To accommodate confidential compute VMs that expose the simplified CC
measurement protocol instead of the full-blown TCG2 one, fall back to
the former if the latter does not exist.
The CC protocol was designed to be used in this manner, which is why the
types and prototypes have been kept the same where possible. So reuse
the existing code, and only deviate from the TCG2 code path where
needed.

If the virtual firmware implements TPM support, TCG2 protocol will be
used for kernel measurements and event logging support. But in CC
environment, not all platforms support or enable the TPM feature. UEFI
specification [1] exposes protocol and interfaces used for kernel
measurements in CC platforms without TPM support.
More details about the EFI CC measurements and logging can be found
in [1].

The LINUX_EFI_ GUID identifiers are only intended to be used to refer to
GUIDs that are part of the Linux implementation, and are not considered
external ABI. (Famous last words).
GUIDs that already have a symbolic name in the spec should use that
name, to avoid confusion between firmware components. So use the
official name EFI_TCG2_FINAL_EVENTS_TABLE_GUID for the TCG2 'final
events' configuration table.

Our efi_tcg2_tagged_event is not defined in the EFI spec, but it is not
a local invention either: it was taken from the TCG PC Client spec,
where it is called TCG_PCClientTaggedEvent.
Note that this spec also contains some guidance on how to populate it,
which is not being followed closely at the moment; it claims that the
event size should cover the TCG_PCClientTaggedEvent and its payload
only, but it currently covers the preceding efi_tcg2_event too.
However, this directly contradicts the TCG EFI protocol specification,
which states very clearly that the event size should cover the entire
data structure, including the leading efi_tcg2_event_t struct.
So rename the struct and document its provenance, but retain the
existing logic to populate the size field.

====================
Support Multi-PF netdev (Socket Direct)
This series adds support for combining multiple devices (PFs) of the
same port under one netdev instance. Passing traffic through different
devices belonging to different NUMA sockets saves cross-numa traffic and
allows apps running on the same netdev from different numas to still
feel a sense of proximity to the device and achieve improved
performance.
We achieve this by grouping PFs together, and creating the netdev only
once all group members are probed. Symmetrically, we destroy the netdev
once any of the PFs is removed.
The channels are distributed between all devices, a proper configuration
would utilize the correct close numa when working on a certain app/cpu.
We pick one device to be a primary (leader), and it fills a special
role. The other devices (secondaries) are disconnected from the network
in the chip level (set to silent mode). All RX/TX traffic is steered
through the primary to/from the secondaries.
Currently, we limit the support to PFs only, and up to two devices
(sockets).

Use BIT() where makes sense. This alings usage of bit operations
in the same pieces of code. Moreover, strictly speaking by the
letter of the C standard, left shift of 1 by 31 bits is UB (undefined
behaviour), switching to BIT() addresses that as well.
