Pull CXL (Compute Express Link) updates from Dan Williams:
"The main new functionality this time is work to allow Linux to
natively handle CXL link protocol errors signalled via PCIe AER for
current generation CXL platforms. This required some enlightenment of
the PCIe AER core to workaround the fact that current generation RCH
(Restricted CXL Host) platforms physically hide topology details and
registers via a mechanism called RCRB (Root Complex Register Block).
The next major highlight is reworks to address bugs in parsing region
configurations for next generation VH (Virtual Host) topologies. The
old broken algorithm is replaced with a simpler one that significantly
increases the number of region configurations supported by Linux. This
is again relevant for error handling so that forward and reverse
address translation of memory errors can be carried out by Linux for
memory regions instantiated by platform firmware.
As for other cross-tree work, the ACPI table parsing code has been
refactored for reuse parsing the "CDAT" structure which is an
ACPI-like data structure that is reported by CXL devices. That work is
in preparation for v6.8 support for CXL QoS. Think of this as dynamic
generation of NUMA node topology information generated by Linux rather
than platform firmware.
Lastly, a number of internal object lifetime issues have been resolved
along with misc. fixes and feature updates (decoders_committed sysfs
ABI).
Summary:
- Add support for RCH (Restricted CXL Host) Error recovery
- Fix several region assembly bugs
- Fix mem-device lifetime issues relative to the sanitize command and
RCH topology.
- Refactor ACPI table parsing for CDAT parsing re-use in preparation
for CXL QOS support"

Pull unified attestation reporting from Dan Williams:
"In an ideal world there would be a cross-vendor standard attestation
report format for confidential guests along with a common device
definition to act as the transport.
In the real world the situation ended up with multiple platform
vendors inventing their own attestation report formats with the
SEV-SNP implementation being a first mover to define a custom
sev-guest character device and corresponding ioctl(). Later, this
configfs-tsm proposal intercepted an attempt to add a tdx-guest
character device and a corresponding new ioctl(). It also anticipated
ARM and RISC-V showing up with more chardevs and more ioctls().
The proposal takes for granted that Linux tolerates the vendor report
format differentiation until a standard arrives. From talking with
folks involved, it sounds like that standardization work is unlikely
to resolve anytime soon. It also takes the position that kernfs ABIs
are easier to maintain than ioctl(). The result is a shared configfs
mechanism to return per-vendor report-blobs with the option to later
support a standard when that arrives.
Part of the goal here also is to get the community into the
"uncomfortable, but beneficial to the long term maintainability of the
kernel" state of talking to each other about their differentiation and
opportunities to collaborate. Think of this like the device-driver
equivalent of the common memory-management infrastructure for
confidential-computing being built up in KVM.
As for establishing an "upstream path for cross-vendor
confidential-computing device driver infrastructure" this is something
I want to discuss at Plumbers. At present, the multiple vendor
proposals for assigning devices to confidential computing VMs likely
needs a new dedicated repository and maintainer team, but that is a
discussion for v6.8.
For now, Greg and Thomas have acked this approach and this is passing
is AMD, Intel, and Google tests.
Summary:
- Introduce configfs-tsm as a shared ABI for confidential computing
attestation reports
- Convert sev-guest to additionally support configfs-tsm alongside
its vendor specific ioctl()
- Added signed attestation report retrieval to the tdx-guest driver
forgoing a new vendor specific ioctl()
- Misc cleanups and a new __free() annotation for kvfree()"

Because a) helper is exported to other parts of the scheduler and
b) there isn't a plain drm_sched_wakeup to begin with, I think we can
drop the suffix and by doing so separate the intimiate knowledge
between the scheduler components a bit better.

Pull mtd updates from Miquel Raynal:
"The main set of changes is related to Uwe's work converting platform
remove callbacks to return void. Comes next (in number of changes)
Kees' additional structures annotations to improve the sanitizers. The
usual amount of cleanups apply.
About the more substancial contribution, one main function of the
partitions core could return an error which was not checked, this is
now fixed. On the bindings side, fixed partitions can now have a
compression property. Finally, an erroneous situation is now always
avoided in the MAP RAM driver.
CFI:
- A several years old byte swap has been fixed.
NAND:
- The subsystem has, as usual, seen a bit of cleanup being done this
cycle, typically return values of platform_get_irq() and
devm_kasprintf(). There is also a better ECC check in the Arasan
driver. This comes with smaller misc changes.
- In the SPI-NAND world there is now support for Foresee F35SQA002G,
Winbond W25N and XTX XT26 chips.
SPI NOR:
- For SPI NOR we cleaned the flash info entries in order to have them
slimmer and self explanatory. In order to make the entries as slim
as possible, we introduced sane default values so that the actual
flash entries don't need to specify them. We now use a flexible
macro to specify the flash ID instead of the previous INFOx()
macros that had hardcoded ID lengths.
Instead of:
{ "w25q512nwm", INFO(0xef8020, 0, 64 * 1024, 0)
OTP_INFO(256, 3, 0x1000, 0x1000) },
We now use:
.id = SNOR_ID(0xef, 0x80, 0x20),
.name = "w25q512nwm",
.otp = SNOR_OTP(256, 3, 0x1000, 0x1000),
- We also removed some flash entries: the very old Catalyst SPI
EEPROMs that were introduced once with the SPI-NOR subsystem, and a
Fujitsu MRAM. Both should use the at25 EEPROM driver. The latter
even has device tree bindings for the at25 driver.
- We made sure that the conversion didn't introduce any unwanted
changes by comparing the .rodata segment before and after the
conversion. The patches landed in linux-next immediately after
v6.6-rc2, we haven't seen any regressions yet.
- Apart of the autumn cleaning we introduced a new flash entry,
at25ff321a, and added block protection support for mt25qu512a"

Currently the pinctrl GPIO helpers all take a number from the global
GPIO numberspace - of which we're trying to get rid of as argument.
These helpers are almost universally called from GPIOLIB driver
callbacks which take a pointer to the backing gpio_chip and the
controller-relative offset as arguments.
Let's provide improved variants of these functions that match the
GPIOLIB signatures as the first step in removing the older flavor.

Pull staging driver updates from Greg KH:
"Here is the big set of staging driver updates for 6.7-rc1. A bit
bigger than 6.6 this time around, as it coincided with the Outreachy
and mentorship application process, so we got a bunch of new
developers sending in their first changes, which is nice to see.
Also in here is a removal of the qlge ethernet driver, and the
rtl8192u wireless driver. Both of these were very old and no one was
maintaining them, the wireless driver removal was due to no one using
it anymore, and no hardware to be found, and is part of a larger
effort to remove unused and old wifi drivers from the system.
The qlge ethernet driver did have one user pop up after it was
dropped, and we are working with the network mainainers to figure out
what tree it will come back in from and who will be responsible for
it, and if it really is being used or not. Odds are it will show up in
a network subsystem pull request after -rc1 is out, but we aren't sure
yet.
Other smaller changes in here are:
- Lots of vc04_services work by Umang to clean up the mess created by
the rpi developers long ago, bringing it almost into good enough
shape to get out of staging, hopefully next major release, it's
getting close.
- rtl8192e variable cleanups and removal of unused code and
structures
- vme_user coding style cleanups
- other small coding style cleanups to lots of the staging drivers
- octeon typedef removals, and then last-minute revert when it was
found to break the build in some configurations (it's a hard driver
to build properly, none of the normal automated testing catches
it.)

IBI shall be handled in order they appear on the bus. Otherwise could hit
case when order of handling them in device driver will be different. It may
lead to invalid assembling fragmented packets or events order broken.
Added separate workqueue with option WQ_MEM_RECLAIM for each device driver.
This ensures IBI handling order and improves IBI handling performance: IBI
handlers for device B are not blocked by IBI handlers for device A.
Original solution (single workqueue in main driver) was able to handle also
general IBI (not related to specific device) like HJ or MR. So leaving this
for such purposes.

Inode operations that create a new filesystem object such as ->mknod,
->create, ->mkdir() and others don't take a {g,u}id argument explicitly.
Instead the caller's fs{g,u}id is used for the {g,u}id of the new
filesystem object.
In order to ensure that the correct {g,u}id is used map the caller's
fs{g,u}id for creation requests. This doesn't require complex changes.
It suffices to pass in the relevant idmapping recorded in the request
message. If this request message was triggered from an inode operation
that creates filesystem objects it will have passed down the relevant
idmaping. If this is a request message that was triggered from an inode
operation that doens't need to take idmappings into account the initial
idmapping is passed down which is an identity mapping.
This change uses a new cephfs protocol extension CEPHFS_FEATURE_HAS_OWNER_UIDGID
which adds two new fields (owner_{u,g}id) to the request head structure.
So, we need to ensure that MDS supports it otherwise we need to fail
any IO that comes through an idmapped mount because we can't process it
in a proper way. MDS server without such an extension will use caller_{u,g}id
fields to set a new inode owner UID/GID which is incorrect because caller_{u,g}id
values are unmapped. At the same time we can't map these fields with an
idmapping as it can break UID/GID-based permission checks logic on the
MDS side. This problem was described with a lot of details at [1], [2].

Pull landlock updates from Mickaël Salaün:
"A Landlock ruleset can now handle two new access rights:
LANDLOCK_ACCESS_NET_BIND_TCP and LANDLOCK_ACCESS_NET_CONNECT_TCP. When
handled, the related actions are denied unless explicitly allowed by a
Landlock network rule for a specific port.
The related patch series has been reviewed for almost two years, it
has evolved a lot and we now have reached a decent design, code and
testing. The refactored kernel code and the new test helpers also
bring the foundation to support more network protocols.
Test coverage for security/landlock is 92.4% of 710 lines according to
gcc/gcov-13, and it was 93.1% of 597 lines before this series. The
decrease in coverage is due to code refactoring to make the ruleset
management more generic (i.e. dealing with inodes and ports) that also
added new WARN_ON_ONCE() checks not possible to test from user space.
syzkaller has been updated accordingly [4], and such patched instance
(tailored to Landlock) has been running for a month, covering all the
new network-related code [5]"

git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
Pull tracing updates from Steven Rostedt:
- Remove eventfs_file descriptor
This is the biggest change, and the second part of making eventfs
create its files dynamically.
In 6.6 the first part was added, and that maintained a one to one
mapping between eventfs meta descriptors and the directories and file
inodes and dentries that were dynamically created. The directories
were represented by a eventfs_inode and the files were represented by
a eventfs_file.
In v6.7 the eventfs_file is removed. As all events have the same
directory make up (sched_switch has an "enable", "id", "format", etc
files), the handing of what files are underneath each leaf eventfs
directory is moved back to the tracing subsystem via a callback.
When an event is added to the eventfs, it registers an array of
evenfs_entry's. These hold the names of the files and the callbacks
to call when the file is referenced. The callback gets the name so
that the same callback may be used by multiple files. The callback
then supplies the filesystem_operations structure needed to create
this file.
This has brought the memory footprint of creating multiple eventfs
instances down by 2 megs each!
- User events now has persistent events that are not associated to a
single processes. These are privileged events that hang around even
if no process is attached to them
- Clean up of seq_buf
There's talk about using seq_buf more to replace strscpy() and
friends. But this also requires some minor modifications of seq_buf
to be able to do this
- Expand instance ring buffers individually
Currently if boot up creates an instance, and a trace event is
enabled on that instance, the ring buffer for that instance and the
top level ring buffer are expanded (1.4 MB per CPU). This wastes
memory as this happens when nothing is using the top level instance
- Other minor clean ups and fixes

git://git.kernel.org/pub/scm/linux/kernel/git/printk/linux
Pull printk updates from Petr Mladek:
- Another preparation step for introducing printk kthreads. The main
piece is a per-console lock with several features:
- Support three priorities: normal, emergency, and panic. They will
be defined by a context where the lock is taken. A context with a
higher priority is allowed to take over the lock from a context
with a lower one.
The plan is to use the emergency context for Oops and WARN()
messages, and also by watchdogs.
The panic() context will be used on panic CPU.
- The owner might enter/exit regions where it is not safe to take
over the lock. It allows the take over the lock a safe way in the
middle of a message.
For example, serial drivers emit characters one by one. And the
serial port is in a safe state in between.
Only the final console_flush_in_panic() will be allowed to take
over the lock even in the unsafe state (last chance, pray, and
hope).
- A higher priority context might busy wait with a timeout. The
current owner is informed about the waiter and releases the lock
on exit from the unsafe state.
- The new lock is safe even in atomic contexts, including NMI.
Another change is a safe manipulation of per-console sequence number
counter under the new lock.
- simple_strntoull() micro-optimization
- Reduce pr_flush() pooling time.
- Calm down false warning about possible buffer invalid access to
console buffers when CONFIG_PRINTK is disabled.
[ .. and Thomas Gleixner wants to point out that while several of the
commits are attributed to him, he only authored the early versions of
said commits, and that John Ogness and Petr Mladek have been the ones

Add support to partially execute a slice which is resized to zero.
Executing a zero size slice in a BO should mean that there is no DMA
transfers involved but you should still configure doorbell and semaphores.
For example consider a BO of size 18K and it is sliced into 3 6K slices
and user calls partial execute ioctl with resize as 10K.
slice 0 - size is 6k and offset is 0, so resize of 10K will not cut short
this slice hence we send the entire slice for execution.
slice 1 - size is 6k and offset is 6k, so resize of 10K will cut short this
slice and only the first 4k should be DMA along with configuring
doorbell and semaphores.
slice 2 - size is 6k and offset is 12k, so resize of 10k will cut short
this slice and no DMA transfer would be involved but we should
would configure doorbell and semaphores.
This change begs to change the behavior of 0 resize. Currently, 0 resize
partial execute ioctl behaves exactly like execute ioctl i.e. no resize.
After this patch all the slice in BO should behave exactly like slice 2 in
above example.
Refactor copy_partial_exec_reqs() to make it more readable and less
complex.

with all flags being set.
v2:
- While fixing this bug, add PSH flag handling and represent
flags the way tcpdump does : [S], [S.], [P.]
- Print 4-tuples more consistently between families.

After blamed commit, TFO client-ack-dropped-then-recovery-ms-timestamps
packetdrill test failed.
David Morley and Neal Cardwell started investigating and Neal pointed
that we had :
tcp_conn_request()
tcp_try_fastopen()
-> tcp_fastopen_create_child
-> child = inet_csk(sk)->icsk_af_ops->syn_recv_sock()
-> tcp_create_openreq_child()
-> copy req_usec_ts from req:
newtp->tcp_usec_ts = treq->req_usec_ts;
// now the new TFO server socket always does usec TS, no matter
// what the route options are...
send_synack()
-> tcp_make_synack()
// disable tcp_rsk(req)->req_usec_ts if route option is not present:
if (tcp_rsk(req)->req_usec_ts < 0)
tcp_rsk(req)->req_usec_ts = dst_tcp_usec_ts(dst);
tcp_conn_request() has the initial dst, we can initialize
tcp_rsk(req)->req_usec_ts there instead of later in send_synack();
This means tcp_rsk(req)->req_usec_ts can be a boolean.
Many thanks to David an Neal for their help.

The comment for idr_for_each_entry_ul() states
after normal termination @entry is left with the value NULL
This is not correct in the case where UINT_MAX has an entry in the idr.
In that case @entry will be non-NULL after termination.
No current code depends on the documentation being correct, but to
save future code we should fix it.
Also fix idr_for_each_entry_continue_ul(). While this is not documented
as leaving @entry as NULL, the mellanox driver appears to depend on
it doing so. So make that explicit in the documentation as well as in
the code.

The lengthier patch series are
- 'kdump: use generic functions to simplify crashkernel reservation

consolidation of the 'crashkernel=' kernel parameter handling
- After much discussion, David Laight's 'minmax: Relax type checks in
min() and max()' is here. Hopefully reduces some typecasting and
the use of min_t() and max_t()

Pull MM updates from Andrew Morton:
"Many singleton patches against the MM code. The patch series which are
included in this merge do the following:
- Kemeng Shi has contributed some compation maintenance work in the
series 'Fixes and cleanups to compaction'
- Joel Fernandes has a patchset ('Optimize mremap during mutual
alignment within PMD') which fixes an obscure issue with mremap()'s
pagetable handling during a subsequent exec(), based upon an
implementation which Linus suggested
- More DAMON/DAMOS maintenance and feature work from SeongJae Park i
the following patch series:
mm/damon: misc fixups for documents, comments and its tracepoint
mm/damon: add a tracepoint for damos apply target regions
mm/damon: provide pseudo-moving sum based access rate
mm/damon: implement DAMOS apply intervals
mm/damon/core-test: Fix memory leaks in core-test
mm/damon/sysfs-schemes: Do DAMOS tried regions update for only one apply interval
- In the series 'Do not try to access unaccepted memory' Adrian
Hunter provides some fixups for the recently-added 'unaccepted
memory' feature. To increase the feature's checking coverage. 'Plug
a few gaps where RAM is exposed without checking if it is
unaccepted memory'
- In the series 'cleanups for lockless slab shrink' Qi Zheng has done
some maintenance work which is preparation for the lockless slab
shrinking code
- Qi Zheng has redone the earlier (and reverted) attempt to make slab
shrinking lockless in the series 'use refcount+RCU method to
implement lockless slab shrink'
- David Hildenbrand contributes some maintenance work for the rmap
code in the series 'Anon rmap cleanups'
- Kefeng Wang does more folio conversions and some maintenance work
in the migration code. Series 'mm: migrate: more folio conversion
and unification'
- Matthew Wilcox has fixed an issue in the buffer_head code which was
causing long stalls under some heavy memory/IO loads. Some cleanups
were added on the way. Series 'Add and use bdev_getblk()'
- In the series 'Use nth_page() in place of direct struct page
manipulation' Zi Yan has fixed a potential issue with the direct
manipulation of hugetlb page frames
- In the series 'mm: hugetlb: Skip initialization of gigantic tail
struct pages if freed by HVO' has improved our handling of gigantic
pages in the hugetlb vmmemmep optimizaton code. This provides
significant boot time improvements when significant amounts of
gigantic pages are in use
- Matthew Wilcox has sent the series 'Small hugetlb cleanups' - code
rationalization and folio conversions in the hugetlb code
- Yin Fengwei has improved mlock()'s handling of large folios in the
series 'support large folio for mlock'

prctl so that userspace may direct the kernel to not automatically
propagate the denial to child processes. The series is named 'MDWE
without inheritance'
- Kefeng Wang has provided the series 'mm: convert numa balancing
functions to use a folio' which does what it says
- In the series 'mm/ksm: add fork-exec support for prctl' Stefan
Roesch makes is possible for a process to propagate KSM treatment
across exec()
- Huang Ying has enhanced memory tiering's calculation of memory
distances. This is used to permit the dax/kmem driver to use 'high
bandwidth memory' in addition to Optane Data Center Persistent
Memory Modules (DCPMM). The series is named 'memory tiering:
calculate abstract distance based on ACPI HMAT'
- In the series 'Smart scanning mode for KSM' Stefan Roesch has
optimized KSM by teaching it to retain and use some historical
information from previous scans
- Yosry Ahmed has fixed some inconsistencies in memcg statistics in
the series 'mm: memcg: fix tracking of pending stats updates
values'
- In the series 'Implement IOCTL to get and optionally clear info
about PTEs' Peter Xu has added an ioctl to /proc/<pid>/pagemap
which permits us to atomically read-then-clear page softdirty
state. This is mainly used by CRIU
- Hugh Dickins contributed the series 'shmem,tmpfs: general
maintenance', a bunch of relatively minor maintenance tweaks to
this code
- Matthew Wilcox has increased the use of the VMA lock over
file-backed page faults in the series 'Handle more faults under the
VMA lock'. Some rationalizations of the fault path became possible
as a result

- khugepaged conversions from Vishal Moola in the series 'Some
khugepaged folio conversions'"
[ bcachefs conflicts with the dynamically allocated shrinkers have been
resolved as per Stephen Rothwell in
https://lore.kernel.org/all/20230913093553.4290421e@canb.auug.org.au/
