Prepare for the coming implementation by GCC and Clang of the __counted_by
attribute. Flexible array members annotated with __counted_by can have
their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS
(for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family
functions).
As found with Coccinelle[1], add __counted_by for struct fw_node.

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()"

git://git.kernel.org/pub/scm/linux/kernel/git/mtd/linux
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"

Pull 9p updates from Dominique Martinet:
A bunch of small fixes:
- three W=1 warning fixes: the NULL -> "" replacement isn't trivial
but is serialized identically by the protocol layer and has been
tested
- one syzbot/KCSAN datarace annotation where we don't care about
users messing with the fd they passed to mount -t 9p
- removing a declaration without implementation
- yet another race fix for trans_fd around connection close: the
'err' field is also used in potentially racy calls and this isn't
complete, but it's better than what we had
- and finally a theorical memory leak fix on serialization failure"

Pull x86 microcode loading updates from Borislac Petkov:
"Major microcode loader restructuring, cleanup and improvements by
Thomas Gleixner:
- Restructure the code needed for it and add a temporary initrd
mapping on 32-bit so that the loader can access the microcode
blobs. This in itself is a preparation for the next major
improvement:
- Do not load microcode on 32-bit before paging has been enabled.
Handling this has caused an endless stream of headaches, issues,
ugly code and unnecessary hacks in the past. And there really
wasn't any sensible reason to do that in the first place. So switch
the 32-bit loading to happen after paging has been enabled and turn
the loader code "real purrty" again
- Drop mixed microcode steppings loading on Intel - there, a single
patch loaded on the whole system is sufficient
- Rework late loading to track which CPUs have updated microcode
successfully and which haven't, act accordingly
- Move late microcode loading on Intel in NMI context in order to
guarantee concurrent loading on all threads
- Make the late loading CPU-hotplug-safe and have the offlined
threads be woken up for the purpose of the update
- Add support for a minimum revision which determines whether late
microcode loading is safe on a machine and the microcode does not
change software visible features which the machine cannot use
anyway since feature detection has happened already. Roughly, the
minimum revision is the smallest revision number which must be
loaded currently on the system so that late updates can be allowed
- Other nice leanups, fixess, etc all over the place"
* tag 'x86_microcode_for_v6.7_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (40 commits)

The raw NAND subsystem has, as usual, seen a bit of cleanup being done
this cycle, typically return values of platform_get_irq() and
devm_kasprintf(), plus structure annotations for sanitizers. 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.

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.

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

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.

The `i3c_master_bus_init` function may attach the I2C devices before the
I3C bus initialization. In this flow, the DAT `alloc_entry`` will be used
before the DAT `init`. Additionally, if the `i3c_master_bus_init` fails,
the DAT `cleanup` will execute before the device is detached, which will
execue DAT `free_entry` function. The above scenario can cause the driver
to use DAT_data when it is NULL.

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]"

BIT 20: TIMEOUT error
The module has stalled too long in a frame. This happens when:
- The TX FIFO or RX FIFO is not handled and the bus is stuck in the
middle of a message,
- No STOP was issued and between messages,
- IBI manual is used and no decision was made.
The maximum stall period is 100 μs.
This can be considered as being just a warning as the system IRQ latency
can easily be greater than 100us.

MSTATUS[RXPEND] is only updated after the data transfer cycle started. This
creates an issue when the I3C clock is slow, and the CPU is running fast
enough that MSTATUS[RXPEND] may not be updated when the code reaches
checking point. As a result, mandatory data can be missed.
Add a wait for MSTATUS[COMPLETE] to ensure that all mandatory data is
already in FIFO. It also works without mandatory data.

If an In-Band Interrupt (IBI) occurs and IBI work thread is not immediately
scheduled, when svc_i3c_master_priv_xfers() initiates the I3C transfer and
attempts to send address 0x7e, the target interprets it as an
IBI handler and returns the target address 0x0a.
However, svc_i3c_master_priv_xfers() does not handle this case and proceeds
with other transfers, resulting in incorrect data being returned.
Add IBIWON check in svc_i3c_master_xfer(). In case this situation occurs,
return a failure to the driver.

git://git.kernel.org/pub/scm/linux/kernel/git/perf/perf-tools
Pull perf tools updates from Namhyung Kim:
"Build:
- Compile BPF programs by default if clang (>= 12.0.1) is available
to enable more features like kernel lock contention, off-cpu
profiling, kwork, sample filtering and so on.
This can be disabled by passing BUILD_BPF_SKEL=0 to make.
- Produce better error messages for bison on debug build (make
DEBUG=1) by defining YYDEBUG symbol internally.
perf record:
- Track sideband events (like FORK/MMAP) from all CPUs even if perf
record targets a subset of CPUs only (using -C option). Otherwise
it may lose some information happened on a CPU out of the target
list.
- Fix checking raw sched_switch tracepoint argument using system BTF.
This affects off-cpu profiling which attaches a BPF program to the
raw tracepoint.
perf lock contention:
- Add --lock-cgroup option to see contention by cgroups. This should
be used with BPF only (using -b option).
$ sudo perf lock con -ab --lock-cgroup -- sleep 1
contended total wait max wait avg wait cgroup
835 14.06 ms 41.19 us 16.83 us /system.slice/led.service
25 122.38 us 13.77 us 4.89 us /

1 491 ns 491 ns 491 ns /system.slice/connectd.service
- Add -G/--cgroup-filter option to see contention only for given
cgroups.
This can be useful when you identified a cgroup in the above
command and want to investigate more on it. It also works with
other output options like -t/--threads and -l/--lock-addr.
$ sudo perf lock con -ab -G /user.slice/user-657345.slice/session-c4.scope -- sleep 1
contended total wait max wait avg wait type caller
8 77.11 us 17.98 us 9.64 us spinlock futex_wake+0xc8
2 24.56 us 14.66 us 12.28 us spinlock tick_do_update_jiffies64+0x25
1 4.97 us 4.97 us 4.97 us spinlock futex_q_lock+0x2a
- Use per-cpu array for better spinlock tracking. This is to improve
performance of the BPF program and to avoid nested contention on a
lock in the BPF hash map.
- Update callstack check for PowerPC. To find a representative caller
of a lock, it needs to look up the call stacks. It ends the lookup
when it sees 0 in the call stack buffer. However, PowerPC call
stacks can have 0 values in the beginning so skip them when it
expects valid call stacks after.
perf kwork:
- Support 'sched' class (for -k option) so that it can see task
scheduling event (using sched_switch tracepoint) as well as irq and
workqueue items.
- Add perf kwork top subcommand to show more accurate cpu utilization
with sched class above. It works both with a recorded data (using
perf kwork record command) and BPF (using -b option). Unlike perf
top command, it does not support interactive mode (yet).
$ sudo perf kwork top -b -k sched

perf bench:
- Add -G/--cgroups option to perf bench sched pipe. The pipe bench is
good to measure context switch overhead. With this option, it puts
the reader and writer tasks in separate cgroups to enforce context
switch between two different cgroups.
Also it needs to set CPU affinity of the tasks in a CPU to
accurately measure the impact of cgroup context switches.
$ sudo perf stat -e context-switches,cgroup-switches -- \

Performance counter stats for 'taskset -c 0 perf bench sched pipe -l 100000 -G AAA,BBB':
200,020 context-switches
200,019 cgroup-switches

Now context-switches and cgroup-switches are almost same. And you
can see the pipe operation took little more.
- Kill child processes when perf bench sched messaging exited
abnormally. Otherwise it'd leave the child doing unnecessary work.
perf test:
- Fix various shellcheck issues on the tests written in shell script.
- Skip tests when condition is not satisfied:
- object code reading test for non-text section addresses.
- CoreSight test if cs_etm// event is not available.
- lock contention test if not enough CPUs.
Event parsing:
- Make PMU alias name loading lazy to reduce the startup time in the
event parsing code for perf record, stat and others in the general
case.
- Lazily compute PMU default config. In the same sense, delay PMU
initialization until it's really needed to reduce the startup cost.
- Fix event term values that are raw events. The event specification
can have several terms including event name. But sometimes it
clashes with raw event encoding which starts with 'r' and has
hex-digits.
For example, an event named 'read' should be processed as a normal
event but it was mis-treated as a raw encoding and caused a
failure.
$ perf stat -e 'uncore_imc_free_running/event=read/' -a sleep 1
event syntax error: '..nning/event=read/'
\___ parser error
Run 'perf list' for a list of valid events
Usage: perf stat [<options>] [<command>]
-e, --event <event> event selector. use 'perf list' to list available events
Event metrics:
- Add "Compat" regex to match event with multiple identifiers.
- Usual updates for Intel, Power10, Arm telemetry/CMN and AmpereOne.
Misc:
- Assorted memory leak fixes and footprint reduction.
- Add "bpf_skeletons" to perf version --build-options so that users
can check whether their perf tools have BPF support easily.
- Fix unaligned access in Intel-PT packet decoder found by
undefined-behavior sanitizer.
- Avoid frequency mode for the dummy event. Surprisingly it'd impact
kernel timer tick handler performance by force iterating all PMU
events.
- Update bash shell completion for events and metrics"

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
who sorted out the details and really should be those who get the
credit - Linus ]
