Quite a lot of kexec work this time around. Many singleton patches in
many places. The notable patch series are:
- nilfs2 folio conversion from Matthew Wilcox in "nilfs2: Folio
conversions for file paths".
- Additional nilfs2 folio conversion from Ryusuke Konishi in "nilfs2:
Folio conversions for directory paths".
- IA64 remnant removal in Heiko Carstens's "Remove unused code after
IA-64 removal".
- Arnd Bergmann has enabled the -Wmissing-prototypes warning everywhere
in "Treewide: enable -Wmissing-prototypes". This had some followup
fixes:
- Nathan Chancellor has cleaned up the hexagon build in the series
"hexagon: Fix up instances of -Wmissing-prototypes".
- Nathan also addressed some s390 warnings in "s390: A couple of
fixes for -Wmissing-prototypes".
- Arnd Bergmann addresses the same warnings for MIPS in his series
"mips: address -Wmissing-prototypes warnings".
- Baoquan He has made kexec_file operate in a top-down-fitting manner
similar to kexec_load in the series "kexec_file: Load kernel at top of
system RAM if required"
- Baoquan He has also added the self-explanatory "kexec_file: print out
debugging message if required".
- Some checkstack maintenance work from Tiezhu Yang in the series
"Modify some code about checkstack".
- Douglas Anderson has disentangled the watchdog code's logging when
multiple reports are occurring simultaneously. The series is "watchdog:
Better handling of concurrent lockups".
- Yuntao Wang has contributed some maintenance work on the crash code in
"crash: Some cleanups and fixes".

Many singleton patches against the MM code. The patch series which
are included in this merge do the following:
- Peng Zhang has done some mapletree maintainance work in the
series
"maple_tree: add mt_free_one() and mt_attr() helpers"
"Some cleanups of maple tree"
- In the series "mm: use memmap_on_memory semantics for dax/kmem"
Vishal Verma has altered the interworking between memory-hotplug
and dax/kmem so that newly added 'device memory' can more easily
have its memmap placed within that newly added memory.
- Matthew Wilcox continues folio-related work (including a few
fixes) in the patch series
"Add folio_zero_tail() and folio_fill_tail()"
"Make folio_start_writeback return void"
"Fix fault handler's handling of poisoned tail pages"
"Convert aops->error_remove_page to ->error_remove_folio"
"Finish two folio conversions"
"More swap folio conversions"
- Kefeng Wang has also contributed folio-related work in the series
"mm: cleanup and use more folio in page fault"
- Jim Cromie has improved the kmemleak reporting output in the
series "tweak kmemleak report format".
- In the series "stackdepot: allow evicting stack traces" Andrey
Konovalov to permits clients (in this case KASAN) to cause
eviction of no longer needed stack traces.
- Charan Teja Kalla has fixed some accounting issues in the page
allocator's atomic reserve calculations in the series "mm:
page_alloc: fixes for high atomic reserve caluculations".
- Dmitry Rokosov has added to the samples/ dorectory some sample
code for a userspace memcg event listener application. See the
series "samples: introduce cgroup events listeners".
- Some mapletree maintanance work from Liam Howlett in the series

- Nhat Pham has improved zswap's approach to writeback in the
series "workload-specific and memory pressure-driven zswap
writeback".
- DAMON/DAMOS feature and maintenance work from SeongJae Park in
the series
"mm/damon: let users feed and tame/auto-tune DAMOS"
"selftests/damon: add Python-written DAMON functionality tests"

Pull slab updates from Vlastimil Babka:
- SLUB: delayed freezing of CPU partial slabs (Chengming Zhou)
Freezing is an operation involving double_cmpxchg() that makes a slab
exclusive for a particular CPU. Chengming noticed that we use it also
in situations where we are not yet installing the slab as the CPU
slab, because freezing also indicates that the slab is not on the
shared list. This results in redundant freeze/unfreeze operation and
can be avoided by marking separately the shared list presence by
reusing the PG_workingset flag.
This approach neatly avoids the issues described in

cgroup: Changes for v6.8
- Yafang Shao added task_get_cgroup1() helper to enable a similar BPF helper so that BPF progs can be more useful on cgroup1 hierarchies. While cgroup1 is mostly in maintenance mode, this addition is very small while having an outsized usefulness for users who are still on cgroup1. Yafang also optimized root cgroup list access by making it RCU protected in the process. - Waiman Long optimized rstat operation leading to substantially lower and more consistent lock hold time while flushing the hierarchical statistics. As the lock can be acquired briefly in various hot paths, this reduction has cascading benefits. - Waiman also improved the quality of isolation for cpuset's isolated partitions. CPUs which are allocated to isolated partitions are now excluded from running unbound work items and cpu_is_isolated() test which is used by vmstat and memcg to reduce interference now includes cpuset isolated CPUs. While it isn't there yet, the hope is eventually reaching parity with the isolation level provided by the `isolcpus` boot param but in a dynamic manner. This involved a couple workqueue patches which were applied directly to cgroup/for-6.8 rather than ping-ponged through the wq tree. This was because the wq code change was small and the area is usually very static and unlikely to cause conflicts. However, luck had it that there was a wq bug fix in the area during the 6.7 cycle which caused a conflict. The conflict is contextual but can be a bit confusing to resolve, so there is one merge from wq/for-6.7-fixes. -----BEGIN PGP SIGNATURE----- iIQEABYKACwWIQTfIjM1kS57o3GsC/uxYfJx3gVYGQUCZYnuJg4cdGpAa2VybmVs Lm9yZwAKCRCxYfJx3gVYGQ5kAP9nMMWqi+R1HeG7+hWROTVjQZ0OM9KRcpZ1TmjF FNbkJgEAzt+sPnoWwYDTSI7pkNeZ/IM7x1qkkKGvENNtUXrz0Ac= =PyYN -----END PGP SIGNATURE----- Merge tag 'cgroup-for-6.8' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup Pull cgroup updates from Tejun Heo: - Yafang Shao added task_get_cgroup1() helper to enable a similar BPF helper so that BPF progs can be more useful on cgroup1 hierarchies.

Scheduler changes for v6.8:
- Energy scheduling:
- Consolidate how the max compute capacity is
used in the scheduler and how we calculate
the frequency for a level of utilization.
- Rework interface between the scheduler and
the schedutil governor
- Simplify the util_est logic
- Deadline scheduler:
- Work more towards reducing SCHED_DEADLINE
starvation of low priority tasks (e.g., SCHED_OTHER)
tasks when higher priority tasks monopolize CPU
cycles, via the introduction of 'deadline servers'
(nested/2-level scheduling).
"Fair servers" to make use of this facility are
not introduced yet.
- EEVDF:
- Introduce O(1) fastpath for EEVDF task selection
- NUMA balancing:
- Tune the NUMA-balancing vma scanning logic some more,
to better distribute the probability
of a particular vma getting scanned.
- Plus misc fixes, cleanups and updates.

in preparation for the WIP 'pull timers at expiry' timer migration model
series (which will replace the current 'push timers at enqueue' migration
model), by Anna-Maria Behnsen:
- Update comments and clean up confusing variable names
- Add debug check to warn about time travel
- Improve/expand timer-wheel tracepoints
- Optimize away unnecessary IPIs for deferrable timers
- Restructure & clean up next_expiry_recalc()
- Clean up forward_timer_base()
- Introduce __forward_timer_base() and use it to simplify

Merge tag 'powerpc-6.8-1' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux
Pull powerpc updates from Michael Ellerman:
- 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.

mm, treewide: introduce NR_PAGE_ORDERS
NR_PAGE_ORDERS defines the number of page orders supported by the page allocator, ranging from 0 to MAX_ORDER, MAX_ORDER + 1 in total. NR_PAGE_ORDERS assists in defining arrays of page orders and allows for more natural iteration over them.

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.

The nouveau ones are mostly memory leaks and debugging cleanups from the GSP (new nvidia firmware) enablement. There are some GSP changes to the message passing code and a subsequent fix for eDP panel turn on, that means my laptop can turn on the panel in GSP mode. These are fairly low chance of disrupting things since GSP is new in 6.7. The final not all in GSP fix is a deadlock seen with i915/nouveau when GSP is used where the the fence and irq paths have locking inversions, I've pushed some irq enablement out to a workqueue, and this has seen some fairly decent testing. amdgpu: - DP MST fix - SMU 13.0.6 fixes - fix displays on macbooks using vega12 - fix VSC and colorimetry on DP/eDP nouveau: - fix deadlock between fence signalling and irq paths - fix GSP memory leaks - fix GSP leftover debug - hide some GSP callback messages - fix GSP display disable path - fix GSP ACPI interaction - handle errors in ctrl messages - use errors info to fix DP link training" * tag 'drm-fixes-2024-01-05' of git://anongit.freedesktop.org/drm/drm: drm/nouveau/dp: Honor GSP link training retry timeouts nouveau: push event block/allowing out of the fence context nouveau/gsp: always free the alloc messages on r535 nouveau/gsp: don't free ctrl messages on errors nouveau/gsp: convert gsp errors to generic errors drm/nouveau/gsp: Fix ACPI MXDM/MXDS method invocations nouveau/gsp: free userd allocation. nouveau/gsp: free acpi object after use nouveau: fix disp disabling with GSP nouveau/gsp: drop some acpi related debug nouveau/gsp: add three notifier callbacks that we see in normal operation (v2) drm/amd/pm: Use gpu_metrics_v1_5 for SMUv13.0.6 drm/amd/pm: Add gpu_metrics_v1_5 drm/amd/pm: Add mem_busy_percent for GCv9.4.3 apu drm/amd/display: Fix sending VSC (+ colorimetry) packets for DP/eDP displays without PSR drm/amdgpu: skip gpu_info fw loading on navi12 drm/amd/display: add nv12 bounding box drm/amd/pm: Update metric table for jpeg/vcn data drm/amd/pm: Use separate metric table for APU drm/amd/display: pbn_div need be updated for hotplug event |
