kdb: move kdb_send_sig() declaration to a better header file
kdb_send_sig() is defined in the signal code and called from kdb, but the declaration is part of the kdb internal code.

However, that presupposes that the FMODE_BACKING flag would already be set which it won't be as that is done in the caller of init_file(). Fix that bug by moving the cleanup of the allocated file into the caller where it belongs in the first place. There's no good reason for init_file() to consume resources it didn't allocate.

fs: move cleanup from init_file() into its callers
The use of file_free_rcu() in init_file() to free the struct that was
allocated by the caller was hacky and we got what we deserved.
Let init_file() and its callers take care of cleaning up each after
their own allocated resources on error.

NFS client updates for Linux 6.5
Highlights include:
Stable fixes and other bugfixes:
- nfs: don't report STATX_BTIME in ->getattr
- Revert "NFSv4: Retry LOCK on OLD_STATEID during delegation return"
since it breaks NFSv4 state recovery.
- NFSv4.1: freeze the session table upon receiving NFS4ERR_BADSESSION
- Fix the NFSv4.2 xattr cache shrinker_id
- Force a ctime update after a NFSv4.2 SETXATTR call
Features and cleanups:
- NFS and RPC over TLS client code from Chuck Lever.
- Support for use of abstract unix socket addresses with the rpcbind
daemon.
- Sysfs API to allow shutdown of the kernel RPC client and prevent
umount() hangs if the server is known to be permanently down.
- XDR cleanups from Anna.

A single regression fix for x86:
Moving the invocation of arch_cpu_finalize_init() earlier in the boot process caused a boot regression on IBT enabled system. The root cause is not the move of arch_cpu_finalize_init() itself. The system fails to boot because the subsequent efi_enter_virtual_mode() code has a non-IBT safe EFI call inside. This was never noticed because IBT was enabled after the EFI initialization. Switching the EFI call to use the IBT safe wrapper cures the problem. -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEQp8+kY+LLUocC4bMphj1TA10mKEFAmSga0ITHHRnbHhAbGlu dXRyb25peC5kZQAKCRCmGPVMDXSYofPAEADCjJ40zgv7cbi6VTKudQhASwclWimy zJk1hR6u+Gt7slDAOS/lcHwPzwPB2wn9VsdTHClSHeJbdT3GBKMCOQOFaj1mHvOW e9H7PKUn76OLUSQtpquNiXvnkZGGK/FkTBCi1dEX3xhrWYQ9EVAg/9gDPLtCR5vv cS95KAETGq/7Krxdkgn/w1cav13t+WA25EjAochwG0DAiqVpj+QK1X+dvm8S9F4I MAyLboPK7cN7WijMVxruy1ho+n8L4ZHv6GcOnd9hD/Z6Tyk48hTvQOpVD7V3h1Yc GWzXVyOETuDAwBubfbxCFWQ2nbzwE6uCTGlwyaCmCxixxNSXhyiysvLOLgZr+tD9 97/Z2tZM+nWjnL8vXvpVCKTNJHTssgh2GvUiKzecRuJWK/FoyfbiZllztVPewmRx k9hwf1qMzW8/XpcpfuY9XkfOBIPDUqWpKBtl9XpprU3EFOjEFfkNmdhGPFHkKefG v0LL3dc19f5N8/tFJN5mEww1ZolgQ0aIKqvT0CeY0x0MvCTT214OWb59tzrn+dw3 tth+pGIZnh+5qM8geE1jQ162zkg+r0UaK4TClTqgwzrxIUHmBygI+LVnuPu2iYMi KlJSaOiU60NjzzVVujbSFclPIgkcINuVuQh5zyTGMBLtRgxPzARKTr8v9dqalHeH xcmDJsrKIpMy7A== =T/8G -----END PGP SIGNATURE----- Merge tag 'x86-urgent-2023-07-01' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull x86 fix from Thomas Gleixner: "A single regression fix for x86: Moving the invocation of arch_cpu_finalize_init() earlier in the boot process caused a boot regression on IBT enabled system.

Merge tag 'cxl-for-6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl
Pull CXL updates from Dan Williams:
"The highlights in terms of new functionality are support for the
standard CXL Performance Monitor definition that appeared in CXL 3.0,
support for device sanitization (wiping all data from a device),
secure-erase (re-keying encryption of user data), and support for
firmware update. The firmware update support is notable as it reuses
the simple sysfs_upload interface to just cat(1) a blob to a sysfs
file and pipe that to the device.
Additionally there are a substantial number of cleanups and
reorganizations to get ready for RCH error handling (RCH == Restricted
CXL Host == current shipping hardware generation / pre CXL-2.0
topologies) and type-2 (accelerator / vendor specific) devices.
For vendor specific devices they implement a subset of what the
generic type-3 (generic memory expander) driver expects. As a result
the rework decouples optional infrastructure from the core driver
context.
For RCH topologies, where the specification working group did not want
to confuse pre-CXL-aware operating systems, many of the standard
registers are hidden which makes support standard bus features like
AER (PCIe Advanced Error Reporting) difficult. The rework arranges for
the driver to help the PCI-AER core. Bjorn is on board with this
direction but a late regression disocvery means the completion of this
functionality needs to cook a bit longer, so it is code
reorganizations only for now.
Summary:
- Add infrastructure for supporting background commands along with
support for device sanitization and firmware update
- Introduce a CXL performance monitoring unit driver based on the
common definition in the specification.
- Land some preparatory cleanup and refactoring for the anticipated
arrival of CXL type-2 (accelerator devices) and CXL RCH (CXL-v1.1

mm: Update do_vmi_align_munmap() return semantics
Since do_vmi_align_munmap() will always honor the downgrade request on the success, the callers no longer have to deal with confusing return codes. Since all callers that request downgrade actually want the lock to be dropped, change the downgrade to an unlock request. Note that the lock still needs to be held in read mode during the page table clean up to avoid races with a map request. Update do_vmi_align_munmap() to return 0 for success. Clean up the callers and comments to always expect the unlock to be honored on the success path. The error path will always leave the lock untouched. As part of the cleanup, the wrapper function do_vmi_munmap() and callers to the wrapper are also updated.

KVM/arm64 updates for 6.5
- Eager page splitting optimization for dirty logging, optionally
allowing for a VM to avoid the cost of block splitting in the stage-2
fault path.
- Arm FF-A proxy for pKVM, allowing a pKVM host to safely interact with
services that live in the Secure world. pKVM intervenes on FF-A calls
to guarantee the host doesn't misuse memory donated to the hyp or a
pKVM guest.
- Support for running the split hypervisor with VHE enabled, known as
'hVHE' mode. This is extremely useful for testing the split
hypervisor on VHE-only systems, and paves the way for new use cases
that depend on having two TTBRs available at EL2.
- Generalized framework for configurable ID registers from userspace.
KVM/arm64 currently prevents arbitrary CPU feature set configuration
from userspace, but the intent is to relax this limitation and allow
userspace to select a feature set consistent with the CPU.
- Enable the use of Branch Target Identification (FEAT_BTI) in the
hypervisor.
- Use a separate set of pointer authentication keys for the hypervisor
when running in protected mode, as the host is untrusted at runtime.
- Ensure timer IRQs are consistently released in the init failure
paths.
- Avoid trapping CTR_EL0 on systems with Enhanced Virtualization Traps
(FEAT_EVT), as it is a register commonly read from userspace.
- Erratum workaround for the upcoming AmpereOne part, which has broken
hardware A/D state management.
As a consequence of the hVHE series reworking the arm64 software
features framework, the for-next/module-alloc branch from the arm64 tree
comes along for the ride.

EFI updates for v6.5
Although some more stuff is brewing, the EFI changes that are ready for
mainline are few, so not a lot to pull this cycle:
- improve the PCI DMA paranoia logic in the EFI stub
- some constification changes
- add statfs support to efivarfs
- allow user space to enumerate updatable firmware resources without

xtensa: fix NOMMU build with lock_mm_and_find_vma() conversion
It turns out that xtensa has a really odd configuration situation: you
can do a no-MMU config, but still have the page fault code enabled.
Which doesn't sound all that sensible, but it turns out that xtensa can
have protection faults even without the MMU, and we have this:
config PFAULT
bool "Handle protection faults" if EXPERT && !MMU
default y
help
Handle protection faults. MMU configurations must enable it.
noMMU configurations may disable it if used memory map never
generates protection faults or faults are always fatal.
If unsure, say Y.
which completely violated my expectations of the page fault handling.
End result: Guenter reports that the xtensa no-MMU builds all fail with
arch/xtensa/mm/fault.c: In function ‘do_page_fault’:
arch/xtensa/mm/fault.c:133:8: error: implicit declaration of function ‘lock_mm_and_find_vma’
because I never exposed the new lock_mm_and_find_vma() function for the
no-MMU case.
Doing so is simple enough, and fixes the problem.

md/raid0: add discard support for the 'original' layout
We've found that using raid0 with the 'original' layout and discard
enabled with different disk sizes (such that at least two zones are
created) can result in data corruption. This is due to the fact that
the discard handling in 'raid0_handle_discard()' assumes the 'alternate'
layout. We've seen this corruption using ext4 but other filesystems are
likely susceptible as well.
More specifically, while multiple zones are necessary to create the
corruption, the corruption may not occur with multiple zones if they
layout in such a way the layout matches what the 'alternate' layout
would have produced. Thus, not all raid0 devices with the 'original'
layout, different size disks and discard enabled will encounter this
corruption.
The 3.14 kernel inadvertently changed the raid0 disk layout for different
size disks. Thus, running a pre-3.14 kernel and post-3.14 kernel on the
same raid0 array could corrupt data. This lead to the creation of the
'original' layout (to match the pre-3.14 layout) and the 'alternate' layout
(to match the post 3.14 layout) in the 5.4 kernel time frame and an option
to tell the kernel which layout to use (since it couldn't be autodetected).
However, when the 'original' layout was added back to 5.4 discard support
for the 'original' layout was not added leading this issue.
I've been able to reliably reproduce the corruption with the following
test case:
1. create raid0 array with different size disks using original layout
2. mkfs
3. mount -o discard
4. create lots of files
5. remove 1/2 the files
6. fstrim -a (or just the mount point for the raid0 array)
7. umount
8. fsck -fn /dev/md0 (spews all sorts of corruptions)
Let's fix this by adding proper discard support to the 'original' layout.
The fix 'maps' the 'original' layout disks to the order in which they are
read/written such that we can compare the disks in the same way that the
current 'alternate' layout does. A 'disk_shift' field is added to
'struct strip_zone'. This could be computed on the fly in
raid0_handle_discard() but by adding this field, we save some computation
in the discard path.
Note we could also potentially fix this by re-ordering the disks in the
zones that follow the first one, and then always read/writing them using
the 'alternate' layout. However, that is seen as a more substantial change,
and we are attempting the least invasive fix at this time to remedy the
corruption.
I've verified the change using the reproducer mentioned above. Typically,
the corruption is seen after less than 3 iterations, while the patch has
run 500+ iterations.

mailbox: ti-msgmgr: Fill non-message tx data fields with 0x0
Sec proxy/message manager data buffer is 60 bytes with the last of the
registers indicating transmission completion. This however poses a bit
of a challenge.
The backing memory for sec_proxy / message manager is regular memory,
and all sec proxy does is to trigger a burst of all 60 bytes of data
over to the target thread backing ring accelerator. It doesn't do a
memory scrub when it moves data out in the burst. When we transmit
multiple messages, remnants of previous message is also transmitted
which results in some random data being set in TISCI fields of
messages that have been expanded forward.
The entire concept of backward compatibility hinges on the fact that
the unused message fields remain 0x0 allowing for 0x0 value to be
specially considered when backward compatibility of message extension
is done.
So, instead of just writing the completion register, we continue
to fill the message buffer up with 0x0 (note: for partial message
involving completion, we already do this).
This allows us to scale and introduce ABI changes back also work with
other boot stages that may have left data in the internal memory.
While at this, be consistent and explicit with the data_reg pointer
increment.

Pull pci updates from Bjorn Helgaas:
"Enumeration:
- Export pcie_retrain_link() for use outside ASPM
- Add Data Link Layer Link Active Reporting as another way for
pcie_retrain_link() to determine the link is up
- Work around link training failures (especially on the ASMedia
ASM2824 switch) by training first at 2.5GT/s and then attempting
higher rates
Resource management:
- When we coalesce host bridge windows, remove invalidated resources
from the resource tree so future allocations work correctly
Hotplug:
- Cancel bringup sequence if card is not present, to keep from
blinking Power Indicator indefinitely
- Reassign bridge resources if necessary for ACPI hotplug
Driver binding:
- Convert platform_device .remove() callbacks to return void instead
of a mostly useless int
Power management:
- Reduce wait time for secondary bus to be ready to speed up resume
- Avoid putting EloPOS E2/S2/H2 (as well as Elo i2) PCIe Ports in
D3cold
- Call _REG when transitioning D-states so AML that uses the PCI
config space OpRegion works, which fixes some ASMedia GPIO
controllers after resume
Virtualization:
- Delay extra 250ms after FLR of Solidigm P44 Pro NVMe to avoid KVM
hang when guest is rebooted
- Add function 1 DMA alias quirk for Marvell 88SE9235
Error handling:
- Unexport pci_save_aer_state() since it's only used in drivers/pci/
- Drop recommendation for drivers to configure AER Capability, since
the PCI core does this for all devices
ASPM:
- Disable ASPM on MFD function removal to avoid use-after-free
- Tighten up pci_enable_link_state() and pci_disable_link_state()
interfaces so they don't enable/disable states the driver didn't
specify
- Avoid link retraining race that can happen if ASPM sets link
control parameters while the link is in the midst of training for
some other reason
Endpoint framework:
- Change "PCI Endpoint Virtual NTB driver" Kconfig prompt to be
different from "PCI Endpoint NTB driver"
- Automatically create a function specific attributes group for
endpoint drivers to avoid reference counting issues
- Fix many EPC test issues
- Return pci_epf_type_add_cfs() error if EPF has no driver
- Add kernel-doc for pci_epc_raise_irq() and pci_epc_map_msi_irq()
MSI vector parameters
- Pass EPF device ID to driver probe functions
- Return -EALREADY if EPC has already been started/stopped
- Add linkdown notifier support and use it in qcom-ep
- Add Bus Master Enable event support and use it in qcom-ep
- Add Qualcomm Modem Host Interface (MHI) endpoint driver
- Add Layerscape PME interrupt handling to manage link-up
notification
Cadence PCIe controller driver:
- Wait for link retrain to complete when working around the J721E
i2085 erratum with Gen2 mode
Faraday FTPC100 PCI controller driver:
- Release clock resources on error paths
Freescale i.MX6 PCIe controller driver:
- Save and restore Root Port MSI control to work around hardware defect
Intel VMD host bridge driver:
- Reset VMD config register between soft reboots
- Capture pci_reset_bus() return value instead of printing junk when
it fails
Qualcomm PCIe controller driver:
- Add SDX65 endpoint compatible string to DT binding
- Disable register write access after init for IP v2.3.3, v2.9.0
- Use DWC helpers for enabling/disabling writes to DBI registers
- Hide slot hotplug capability for IP v1.0.0, v1.9.0, v2.1.0, v2.3.2,
v2.3.3, v2.7.0, v2.9.0
- Reuse v2.3.2 post-init sequence for v2.4.0
Renesas R-Car PCIe controller driver:
- Remove unused static pcie_base and pcie_dev
Rockchip PCIe controller driver:
- Remove writes to unused registers
- Write endpoint Device ID using correct register
- Assert PCI Configuration Enable bit after probe so endpoint
responds instead of generating Request Retry Status messages
- Poll waiting for PHY PLLs to lock
- Update RK3399 example DT binding to be valid
- Use RK3399 PCIE_CLIENT_LEGACY_INT_CTRL to generate INTx instead of
manually generating PCIe message
- Use multiple windows to avoid address translation conflicts
- Use u32 (not u16) when accessing 32-bit registers
- Hide MSI-X Capability, since RK3399 can't generate MSI-X
- Set endpoint controller required alignment to 256
Synopsys DesignWare PCIe controller driver:
- Wait for link to come up only if we've initiated link training
Miscellaneous:
- Add pci_clear_master() stub for non-CONFIG_PCI"
