Locking changes for v6.8:
- lock guards:
- Use lock guards in the ptrace code
- Introduce conditional guards to extend to conditional lock
primitives like mutex_trylock()/mutex_lock_interruptible()/etc.
- lockdep:
- Optimize 'struct lock_class' to be smaller
- Update file patterns in MAINTAINERS
- mutexes: Document mutex lifetime rules a bit more

arm64 updates for 6.8
* for-next/cpufeature
- Remove ARM64_HAS_NO_HW_PREFETCH copy_page() optimisation for ye olde
Thunder-X machines.
- Avoid mapping KPTI trampoline when it is not required.
- Make CPU capability API more robust during early initialisation.
* for-next/early-idreg-overrides
- Remove dependencies on core kernel helpers from the early
command-line parsing logic in preparation for moving this code
before the kernel is mapped.
* for-next/fpsimd
- Restore kernel-mode fpsimd context lazily, allowing us to run fpsimd
code sequences in the kernel with pre-emption enabled.
* for-next/kbuild
- Install 'vmlinuz.efi' when CONFIG_EFI_ZBOOT=y.
- Makefile cleanups.
* for-next/lpa2-prep
- Preparatory work for enabling the 'LPA2' extension, which will
introduce 52-bit virtual and physical addressing even with 4KiB
pages (including for KVM guests).
* for-next/misc
- Remove dead code and fix a typo.
* for-next/mm
- Pass NUMA node information for IRQ stack allocations.

in Armv8.8.
- Add support for i.MX8DXL SoCs to the IMX DDR PMU driver.
- Minor PMU driver fixes and optimisations.
* for-next/rip-vpipt
- Remove what support we had for the obsolete VPIPT I-cache policy.
* for-next/selftests
- Improvements to the SVE and SME selftests.
* for-next/stacktrace
- Refactor kernel unwind logic so that it can used by BPF unwinding
and, eventually, reliable backtracing.
* for-next/sysregs
- Update a bunch of register definitions based on the latest XML drop

Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 updates from Will Deacon:
"CPU features:
- Remove ARM64_HAS_NO_HW_PREFETCH copy_page() optimisation for ye
olde Thunder-X machines
- Avoid mapping KPTI trampoline when it is not required
- Make CPU capability API more robust during early initialisation
Early idreg overrides:
- Remove dependencies on core kernel helpers from the early
command-line parsing logic in preparation for moving this code
before the kernel is mapped
FPsimd:
- Restore kernel-mode fpsimd context lazily, allowing us to run
fpsimd code sequences in the kernel with pre-emption enabled
KBuild:
- Install 'vmlinuz.efi' when CONFIG_EFI_ZBOOT=y
- Makefile cleanups
LPA2 prep:
- Preparatory work for enabling the 'LPA2' extension, which will
introduce 52-bit virtual and physical addressing even with 4KiB
pages (including for KVM guests).
Misc:
- Remove dead code and fix a typo
MM:
- Pass NUMA node information for IRQ stack allocations
Perf:
- Add perf support for the Synopsys DesignWare PCIe PMU
- Add support for event counting thresholds (FEAT_PMUv3_TH)
introduced in Armv8.8
- Add support for i.MX8DXL SoCs to the IMX DDR PMU driver.
- Minor PMU driver fixes and optimisations
RIP VPIPT:
- Remove what support we had for the obsolete VPIPT I-cache policy
Selftests:
- Improvements to the SVE and SME selftests
Stacktrace:
- Refactor kernel unwind logic so that it can used by BPF unwinding
and, eventually, reliable backtracing
Sysregs:
- Update a bunch of register definitions based on the latest XML drop
from Arm"

powerpc updates for 6.8
- Add initial support to recognise the HeXin C2000 processor.
- Add papr-vpd and papr-sysparm character device drivers for VPD & sysparm
retrieval, so userspace tools can be adapted to avoid doing raw firmware
calls from userspace.
- Sched domains optimisations for shared processor partitions on P9/P10.
- A series of optimisations for KVM running as a nested HV under PowerVM.
- Other small features and fixes.

Pull vfs cachefiles updates from Christian Brauner:
"This contains improvements for on-demand cachefiles.
If the daemon crashes and the on-demand cachefiles fd is unexpectedly
closed in-flight requests and subsequent read operations associated
with the fd will fail with EIO. This causes issues in various
scenarios as this failure is currently unrecoverable.
The work contained in this pull request introduces a failover mode and
enables the daemon to recover in-flight requested-related objects. A
restarted daemon will be able to process requests as usual.
This requires that in-flight requests are stored during daemon crash
or while the daemon is offline. In addition, a handle to
/dev/cachefiles needs to be stored.
This can be done by e.g., systemd's fdstore (cf. [1]) which enables
the restarted daemon to recover state.
Three new states are introduced in this patchset:
(1) CLOSE
Object is closed by the daemon.
(2) OPEN
Object is open and ready for processing. IOW, the open request
has been handled successfully.
(3) REOPENING
Object has been previously closed and is now reopened due to a
read request.
A restarted daemon can recover the /dev/cachefiles fd from systemd's
fdstore and writes "restore" to the device. This causes the object
state to be reset from CLOSE to REOPENING and reinitializes the
object.
The daemon may now handle the open request. Any in-flight operations
are restored and handled avoiding interruptions for users"

Pull vfs rw updates from Christian Brauner:
"This contains updates from Amir for read-write backing file helpers
for stacking filesystems such as overlayfs:
- Fanotify is currently in the process of introducing pre content
events. Roughly, a new permission event will be added indicating
that it is safe to write to the file being accessed. These events
are used by hierarchical storage managers to e.g., fill the content
of files on first access.
During that work we noticed that our current permission checking is
inconsistent in rw_verify_area() and remap_verify_area().
Especially in the splice code permission checking is done multiple
times. For example, one time for the whole range and then again for
partial ranges inside the iterator.
In addition, we mostly do permission checking before we call
file_start_write() except for a few places where we call it after.
For pre-content events we need such permission checking to be done
before file_start_write(). So this is a nice reason to clean this
all up.
After this series, all permission checking is done before
file_start_write().
As part of this cleanup we also massaged the splice code a bit. We
got rid of a few helpers because we are alredy drowning in special
read-write helpers. We also cleaned up the return types for splice
helpers.
- Introduce generic read-write helpers for backing files. This lifts
some overlayfs code to common code so it can be used by the FUSE
passthrough work coming in over the next cycles. Make Amir and
Miklos the maintainers for this new subsystem of the vfs"

Merge tag 'vfs-6.8.mount' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs
Pull vfs mount updates from Christian Brauner:
"This contains the work to retrieve detailed information about mounts
via two new system calls. This is hopefully the beginning of the end
of the saga that started with fsinfo() years ago.
The LWN articles in [1] and [2] can serve as a summary so we can avoid
rehashing everything here.
At LSFMM in May 2022 we got into a room and agreed on what we want to
do about fsinfo(). Basically, split it into pieces. This is the first
part of that agreement. Specifically, it is concerned with retrieving
information about mounts. So this only concerns the mount information
retrieval, not the mount table change notification, or the extended
filesystem specific mount option work. That is separate work.
Currently mounts have a 32bit id. Mount ids are already in heavy use
by libmount and other low-level userspace but they can't be relied
upon because they're recycled very quickly. We agreed that mounts
should carry a unique 64bit id by which they can be referenced
directly. This is now implemented as part of this work.
The new 64bit mount id is exposed in statx() through the new
STATX_MNT_ID_UNIQUE flag. If the flag isn't raised the old mount id is
returned. If it is raised and the kernel supports the new 64bit mount
id the flag is raised in the result mask and the new 64bit mount id is
returned. New and old mount ids do not overlap so they cannot be
conflated.
Two new system calls are introduced that operate on the 64bit mount
id: statmount() and listmount(). A summary of the api and usage can be
found on LWN as well (cf. [3]) but of course, I'll provide a summary
here as well.
Both system calls rely on struct mnt_id_req. Which is the request
struct used to pass the 64bit mount id identifying the mount to
operate on. It is extensible to allow for the addition of new
parameters and for future use in other apis that make use of mount
ids.
statmount() mimicks the semantics of statx() and exposes a set flags
that userspace may raise in mnt_id_req to request specific information
to be retrieved. A statmount() call returns a struct statmount filled
in with information about the requested mount. Supported requests are
indicated by raising the request flag passed in struct mnt_id_req in
the @mask argument in struct statmount.
Currently we do support:
- STATMOUNT_SB_BASIC:
Basic filesystem info
- STATMOUNT_MNT_BASIC
Mount information (mount id, parent mount id, mount attributes etc)
- STATMOUNT_PROPAGATE_FROM
Propagation from what mount in current namespace
- STATMOUNT_MNT_ROOT
Path of the root of the mount (e.g., mount --bind /bla /mnt returns /bla)
- STATMOUNT_MNT_POINT
Path of the mount point (e.g., mount --bind /bla /mnt returns /mnt)
- STATMOUNT_FS_TYPE
Name of the filesystem type as the magic number isn't enough due to submounts
The string options STATMOUNT_MNT_{ROOT,POINT} and STATMOUNT_FS_TYPE
are appended to the end of the struct. Userspace can use the offsets
in @fs_type, @mnt_root, and @mnt_point to reference those strings
easily.
The struct statmount reserves quite a bit of space currently for
future extensibility. This isn't really a problem and if this bothers
us we can just send a follow-up pull request during this cycle.
listmount() is given a 64bit mount id via mnt_id_req just as
statmount(). It takes a buffer and a size to return an array of the
64bit ids of the child mounts of the requested mount. Userspace can
thus choose to either retrieve child mounts for a mount in batches or
iterate through the child mounts. For most use-cases it will be
sufficient to just leave space for a few child mounts. But for big
mount tables having an iterator is really helpful. Iterating through a
mount table works by setting @param in mnt_id_req to the mount id of
the last child mount retrieved in the previous listmount() call"

Pull vfs super updates from Christian Brauner:
"This contains the super work for this cycle including the long-awaited
series by Jan to make it possible to prevent writing to mounted block
devices:
- Writing to mounted devices is dangerous and can lead to filesystem
corruption as well as crashes. Furthermore syzbot comes with more
and more involved examples how to corrupt block device under a
mounted filesystem leading to kernel crashes and reports we can do
nothing about. Add tracking of writers to each block device and a
kernel cmdline argument which controls whether other writeable
opens to block devices open with BLK_OPEN_RESTRICT_WRITES flag are
allowed.
Note that this effectively only prevents modification of the
particular block device's page cache by other writers. The actual
device content can still be modified by other means - e.g. by
issuing direct scsi commands, by doing writes through devices lower
in the storage stack (e.g. in case loop devices, DM, or MD are
involved) etc. But blocking direct modifications of the block
device page cache is enough to give filesystems a chance to perform
data validation when loading data from the underlying storage and
thus prevent kernel crashes.
Syzbot can use this cmdline argument option to avoid uninteresting
crashes. Also users whose userspace setup does not need writing to
mounted block devices can set this option for hardening. We expect
that this will be interesting to quite a few workloads.
Btrfs is currently opted out of this because they still haven't
merged patches we require for this to work from three kernel
releases ago.
- Reimplement block device freezing and thawing as holder operations
on the block device.
This allows us to extend block device freezing to all devices
associated with a superblock and not just the main device. It also
allows us to remove get_active_super() and thus another function
that scans the global list of superblocks.
Freezing via additional block devices only works if the filesystem
chooses to use @fs_holder_ops for these additional devices as well.
That currently only includes ext4 and xfs.
Earlier releases switched get_tree_bdev() and mount_bdev() to use
@fs_holder_ops. The remaining nilfs2 open-coded version of
mount_bdev() has been converted to rely on @fs_holder_ops as well.
So block device freezing for the main block device will continue to
work as before.
There should be no regressions in functionality. The only special
case is btrfs where block device freezing for the main block device
never worked because sb->s_bdev isn't set. Block device freezing
for btrfs can be fixed once they can switch to @fs_holder_ops but
that can happen whenever they're ready"

firewire fixes for 6.7-final
This pull request includes a single patch to suppress unexpected system reboot in AMD Ryzen machines with PCIe card consisting of Asmedia ASM1083/1085 and VT6306/6307/6308. When 1394 OHCI driver for the card accesses to a specific register in PCI memory space, the system reboot often occurs. The issue affects all versions of Linux kernel as long as the 1394 OHCI driver is included. The mechanism of unexpected system reboot is not clear, so the driver is changed to avoid the access itself when detecting the combination of hardware. -----BEGIN PGP SIGNATURE----- iHUEABYIAB0WIQQE66IEYNDXNBPeGKSsLtaWM8LwEwUCZZf7jQAKCRCsLtaWM8Lw E7D2AP9JXU29+5HRNDYBonC1tEItRK8auF+wbAOe7HcOjRXoUgEA2ghLbA6I2bot iQ/VjH/45TPyo7YAfLw1Kx+vpaysIwU= =EGMc -----END PGP SIGNATURE----- Merge tag 'firewire-fixes-6.7-final' of git://git.kernel.org/pub/scm/linux/kernel/git/ieee1394/linux1394 Pull firewire fix from Takashi Sakamoto: "A single patch to suppress unexpected system reboot in AMD Ryzen machines with PCIe card consisting of Asmedia ASM1083/1085 and VT6306/6307/6308.

firewire: ohci: suppress unexpected system reboot in AMD Ryzen machines and ASM108x/VT630x PCIe cards
VIA VT6306/6307/6308 provides PCI interface compliant to 1394 OHCI. When
the hardware is combined with Asmedia ASM1083/1085 PCIe-to-PCI bus bridge,
it appears that accesses to its 'Isochronous Cycle Timer' register (offset
0xf0 on PCI memory space) often causes unexpected system reboot in any
type of AMD Ryzen machine (both 0x17 and 0x19 families). It does not
appears in the other type of machine (AMD pre-Ryzen machine, Intel
machine, at least), or in the other OHCI 1394 hardware (e.g. Texas
Instruments).
The issue explicitly appears at a commit

nfsd: drop the nfsd_put helper
It's not safe to call nfsd_put once nfsd_last_thread has been called, as
that function will zero out the nn->nfsd_serv pointer.
Drop the nfsd_put helper altogether and open-code the svc_put in its
callers instead. That allows us to not be reliant on the value of that
pointer when handling an error.

drm/nouveau/dp: Honor GSP link training retry timeouts
Turns out that one of the ways that Nvidia's driver handles the pre-LT timeout for eDP panels is by providing a retry timeout in their link training callbacks that we're expected to wait for. Up until now we didn't pay any attention to this parameter. So, start honoring the timeout if link training fails - and retry up to 3 times. The "3 times" bit comes from OpenRM's link training code.

nouveau: push event block/allowing out of the fence context
There is a deadlock between the irq and fctx locks, the irq handling takes irq then fctx lock the fence signalling takes fctx then irq lock This splits the fence signalling path so the code that hits the irq lock is done in a separate work queue. This seems to fix crashes/hangs when using nouveau gsp with i915 primary GPU.

nouveau/gsp: don't free ctrl messages on errors
It looks like for some messages the upper layers need to get access to the results of the message so we can interpret it. Rework the ctrl push interface to not free things and cleanup properly whereever it errors out.

nouveau/gsp: convert gsp errors to generic errors
This should let the upper layers retry as needed on EAGAIN. There may be other values we will care about in the future, but this covers our present needs. Signed-off-by: Dave Airlie <airlied@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20231222043308.3090089-8-airlied@gmail.com |

drm/nouveau/gsp: Fix ACPI MXDM/MXDS method invocations
Currently we get an error from ACPI because both of these arguments expect a single argument, and we don't provide one. I'm not totally clear on what that argument does, but we're able to find the missing value from _acpiCacheMethodData() in src/kernel/platform/acpi_common.c in nvidia's driver. So, let's add that - which doesn't get eDP displays to power on quite yet, but gets rid of the argument warning at least.
