maple_tree: fix node allocation testing on 32 bit
Internal node counting was altered and the 64 bit test was updated,
however the 32bit test was missed.
Restore the 32bit test to a functional state.

perf test task_exit: No need for a cycles event to check if we get an PERF_RECORD_EXIT
The intent of this test is to check we get a PERF_RECORD_EXIT as asked for by setting perf_event_attr.task=1. When the test was written we didn't had the "dummy" event so we went with the default event, "cycles". There were reports of this test failing sometimes, one of these reports was with a PREEMPT_RT_FULL, but I noticed it failing sometimes with an aarch64 Firefly board. In the kernel the call to perf_event_task_output(), that generates the PERF_RECORD_EXIT may fail when there is not enough memory in the ring buffer, if the ring buffer is paused, etc. So switch to using the "dummy" event to use the ring buffer just for what the test was designed for, avoiding uneeded PERF_RECORD_SAMPLEs.

selftests/arm64: fix build failure during the "emit_tests" step
The build failure reported in [1] occurred because commit <9fc96c7c19df>
("selftests: error out if kernel header files are not yet built") added
a new "kernel_header_files" dependency to "all", and that triggered
another, pre-existing problem. Specifically, the arm64 selftests
override the emit_tests target, and that override improperly declares
itself to depend upon the "all" target.
This is a problem because the "emit_tests" target in lib.mk was not
intended to be overridden. emit_tests is a very simple, sequential build
target that was originally invoked from the "install" target, which in
turn, depends upon "all".
That approach worked for years. But with

selftests/mm: give scripts execute permission
When run under run_vmtests.sh, test scripts were failing to run with "permission denied" due to the scripts not being executable. It is also annoying not to be able to directly invoke run_vmtests.sh, which is solved by giving also it the execute permission.

Tracing fixes and clean ups:
- Fix some missing-prototype warnings - Fix user events struct args (did not include size of struct) When creating a user event, the "struct" keyword is to denote that the size of the field will be passed in. But the parsing failed to handle this case. - Add selftest to struct sizes for user events - Fix sample code for direct trampolines. The sample code for direct trampolines attached to handle_mm_fault(). But the prototype changed and the direct trampoline sample code was not updated. Direct trampolines needs to have the arguments correct otherwise it can fail or crash the system. - Remove unused ftrace_regs_caller_ret() prototype. - Quiet false positive of FORTIFY_SOURCE Due to backward compatibility, the structure used to save stack traces in the kernel had a fixed size of 8. This structure is exported to user space via the tracing format file. A change was made to allow more than 8 functions to be recorded, and user space now uses the size field to know how many functions are actually in the stack. But the structure still has size of 8 (even though it points into the ring buffer that has the required amount allocated to hold a full stack. This was fine until the fortifier noticed that the memcpy(&entry->caller, stack, size) was greater than the 8 functions and would complain at runtime about it. Hide this by using a pointer to the stack location on the ring buffer instead of using the address of the entry structure caller field. - Fix a deadloop in reading trace_pipe that was caused by a mismatch between ring_buffer_empty() returning false which then asked to read the data, but the read code uses rb_num_of_entries() that returned zero, and causing a infinite "retry". - Fix a warning caused by not using all pages allocated to store ftrace functions, where this can happen if the linker inserts a bunch of "NULL" entries, causing the accounting of how many pages needed to be off. - Fix histogram synthetic event crashing when the start event is removed and the end event is still using a variable from it. - Fix memory leak in freeing iter->temp in tracing_release_pipe() -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCZLBF6hQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qkswAP4mhdoFFfNosM7+Sh/R4t31IxKZApm9 M2Hf9jgvJ7b65AD/VV1XfO6skw2+5Yn9S4UyNE2MQaYxPwWpONcNFUzZ3Q8= =Nb+7 -----END PGP SIGNATURE----- Merge tag 'trace-v6.5-rc1-3' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing fixes from Steven Rostedt: - Fix some missing-prototype warnings - Fix user events struct args (did not include size of struct) When creating a user event, the "struct" keyword is to denote that the size of the field will be passed in.

perf parse-events: Avoid SEGV if PMU lookup fails for legacy cache terms
libfuzzer found the following command could SEGV:

PERF_TYPE_HW_CACHE which then fails the PMU lookup for the second
legacy cache term.

perf build: Fix broken feature check for libtracefs due to external lib changes
The perf build process auto-detects features and packages already
installed for its build. This is done in directory tools/build/feature.
This directory contains small sample programs. When they successfully
compile the necessary prereqs in form of libraries and header files are
present.
Such a check is also done for libtracefs. And this check fails:
Output before:
# rm -f test-libtracefs.bin; make test-libtracefs.bin
gcc -MD -Wall -Werror -o test-libtracefs.bin test-libtracefs.c \
> test-libtracefs.make.output 2>&1 -ltracefs
make: *** [Makefile:211: test-libtracefs.bin] Error 1
# cat test-libtracefs.make.output
In file included from test-libtracefs.c:2:
/usr/include/tracefs/tracefs.h:11:10: fatal error: \
event-parse.h: No such file or directory
11 | #include <event-parse.h>
| ^~~~~~~~~~~~~~~
compilation terminated.
#
The root cause of this compile error is commit 880885d9c22e
("libtracefs: Remove "traceevent/" from referencing libtraceevent
headers") in the libtracefs project hosted here:
https://git.kernel.org/pub/scm/libs/libtrace/libtracefs.git/
That mentioned patch removes the traceevent/ directory name from
the include statement, causing the file not to be included even
when the libtraceevent-devel package is installed. This package contains
the file referred to in tracefs/tracefs.h:
# rpm -ql libtraceevent-devel
/usr/include/traceevent
/usr/include/traceevent/event-parse.h <----- here
/usr/include/traceevent/event-utils.h
/usr/include/traceevent/kbuffer.h
/usr/include/traceevent/trace-seq.h
/usr/lib64/libtraceevent.so
/usr/lib64/pkgconfig/libtraceevent.pc
#
With this patch the compile succeeds.
Output after:
# rm -f test-libtracefs.bin; make test-libtracefs.bin
gcc -MD -Wall -Werror -o test-libtracefs.bin test-libtracefs.c \
> test-libtracefs.make.output 2>&1 -I/usr/include/traceevent -ltracefs

perf vendor events amd: Fix large metrics
There are cases where a metric requires more events than the number of available counters. E.g. AMD Zen, Zen 2 and Zen 3 processors have four data fabric counters but the "nps1_die_to_dram" metric has eight events. By default, the constituent events are placed in a group and since the events cannot be scheduled at the same time, the metric is not computed. The "all metrics" test also fails because of this. Use the NO_GROUP_EVENTS constraint for such metrics which anyway expect the user to run perf with "--metric-no-group". E.g. $ sudo perf test -v 101 Before: 101: perf all metrics test : --- start --- test child forked, pid 37131 Testing branch_misprediction_ratio Testing all_remote_links_outbound Testing nps1_die_to_dram Metric 'nps1_die_to_dram' not printed in: Error: Invalid event (dram_channel_data_controller_4) in per-thread mode, enable system wide with '-a'.

perf build: Fix library not found error when using CSLIBS
-L only specifies the search path for libraries directly provided in the link line with -l. Because -lopencsd isn't specified, it's only linked because it's a dependency of -lopencsd_c_api. Dependencies like this are resolved using the default system search paths or -rpath-link=... rather than -L. This means that compilation only works if OpenCSD is installed to the system rather than provided with the CSLIBS (-L) option. This could be fixed by adding -Wl,-rpath-link=$(CSLIBS) but that is less conventional than just adding -lopencsd to the link line so that it uses -L. -lopencsd seems to have been removed in commit |

perf probe: Read DWARF files from the correct CU
After switching from dwarf_decl_file() to die_get_decl_file(), it is not
possible to add probes for certain functions:
$ perf probe -x /usr/lib/systemd/systemd-logind match_unit_removed
A function DIE doesn't have decl_line. Maybe broken DWARF?
A function DIE doesn't have decl_line. Maybe broken DWARF?
Probe point 'match_unit_removed' not found.
Error: Failed to add events.
The problem is that die_get_decl_file() uses the wrong CU to search for
the file. elfutils commit e1db5cdc9f has some good explanation for this:
dwarf_decl_file uses dwarf_attr_integrate to get the DW_AT_decl_file
attribute. This means the attribute might come from a different DIE
in a different CU. If so, we need to use the CU associated with the
attribute, not the original DIE, to resolve the file name.
This patch uses the same source of information as elfutils: use attribute
DW_AT_decl_file and use this CU to search for the file.
Fixes:

objtool: initialize all of struct elf
Function elf_open_read() only zero initializes the initial part of
allocated struct elf; num_relocs member was recently added outside the
zeroed part so that it was left uninitialized, resulting in build failures
on some systems.
The partial initialization is a relic of times when struct elf had large
hash tables embedded. This is no longer the case so remove the trap and
initialize the whole structure instead.

- Update AMD IBS event error message since it now support per-process
profiling but no priviledge filters.
$ sudo perf record -e ibs_op//k -C 0
Error:
AMD IBS doesn't support privilege filtering. Try again without
the privilege modifiers (like 'k') at the end.
perf lock contention:
- Support CSV style output using -x option
$ sudo perf lock con -ab -x, sleep 1

1, 24619, 24619, 24619, spinlock, rcu_core+0xd4
- Add --output option to save the data to a file not to be interfered
by other debug messages.
Test:
- Fix event parsing test on ARM where there's no raw PMU nor supports
PERF_PMU_CAP_EXTENDED_HW_TYPE.
- Update the lock contention test case for CSV output.
- Fix a segfault in the daemon command test.
Vendor events (JSON):
- Add has_event() to check if the given event is available on system
at runtime. On Intel machines, some transaction events may not be
present when TSC extensions are disabled.
- Update Intel event metrics.
Misc:
- Sort symbols by name using an external array of pointers instead of
a rbtree node in the symbol. This will save 16-bytes or 24-bytes
per symbol whether the sorting is actually requested or not.
- Fix unwinding DWARF callstacks using libdw when --symfs option is
used.

asm-generic updates for 6.5
These are cleanups for architecture specific header files:
- the comments in include/linux/syscalls.h have gone out of sync
and are really pointless, so these get removed
- The asm/bitsperlong.h header no longer needs to be architecture
specific on modern compilers, so use a generic version for newer
architectures that use new enough userspace compilers
- A cleanup for virt_to_pfn/virt_to_bus to have proper type
checking, forcing the use of pointers

selftests/bpf: Add selftest for check_stack_max_depth bug
Use the bpf_timer_set_callback helper to mark timer_cb as an async callback, and put a direct call to timer_cb in the main subprog. As the check_stack_max_depth happens after the do_check pass, the order does not matter. Without the previous fix, the test passes successfully.

perf test: Fix event parsing test when PERF_PMU_CAP_EXTENDED_HW_TYPE isn't supported.
Arm has multiple PMU types for heterogeneous systems, but doesn't
currently support PERF_PMU_CAP_EXTENDED_HW_TYPE. Make the tests
support both scenarios so that they pass on Arm, and will still pass
once PERF_PMU_CAP_EXTENDED_HW_TYPE support is added.

perf test: Fix event parsing test on Arm
The test looks for a PMU from sysfs with type = PERF_TYPE_RAW when
opening a raw event. Arm doesn't have a real raw PMU, only core PMUs
with unique types other than raw.
Instead of looking for a matching PMU, just test that the event type
was parsed as raw and skip the PMU search on Arm. The raw event type
test should also apply to all platforms so add it outside of the ifdef.

selftests: mptcp: pm_nl_ctl: fix 32-bit support
When using pm_nl_ctl to validate userspace path-manager's behaviours, it was failing on 32-bit architectures ~half of the time. pm_nl_ctl was not reporting any error but the command was not doing what it was expected to do. As a result, the expected linked event was not triggered after and the test failed. This is due to the fact the token given in argument to the application was parsed as an integer with atoi(): in a 32-bit arch, if the number was bigger than INT_MAX, 2147483647 was used instead. This can simply be fixed by using strtoul() instead of atoi(). The errors have been seen "by chance" when manually looking at the results from LKFT. Fixes: |

wireguard: netlink: send staged packets when setting initial private key
Packets bound for peers can queue up prior to the device private key
being set. For example, if persistent keepalive is set, a packet is
queued up to be sent as soon as the device comes up. However, if the
private key hasn't been set yet, the handshake message never sends, and
no timer is armed to retry, since that would be pointless.
But, if a user later sets a private key, the expectation is that those
queued packets, such as a persistent keepalive, are actually sent. So
adjust the configuration logic to account for this edge case, and add a
test case to make sure this works.
Maxim noticed this with a wg-quick(8) config to the tune of:
[Interface]
PostUp = wg set %i private-key somefile
[Peer]
PublicKey = ...
Endpoint = ...
PersistentKeepalive = 25
Here, the private key gets set after the device comes up using a PostUp
script, triggering the bug.

perf evsel amd: Fix IBS error message
AMD IBS can do per-process profiling[1] and is no longer restricted to per-cpu or systemwide only. Remove stale error message. Also, checking just exclude_kernel is not sufficient since IBS does not support any privilege filters. So include all exclude_* checks. And finally, move these checks under tools/perf/arch/x86/ from generic code. Before: $ sudo ./perf record -e ibs_op//k -C 0 Error: AMD IBS may only be available in system-wide/per-cpu mode. Try using -a, or -C and workload affinity After: $ sudo ./perf record -e ibs_op//k -C 0 Error: AMD IBS doesn't support privilege filtering.

perf test: Test perf lock contention CSV output
To verify CSV output, just check the number of separators (",") using
the tr and wc commands like this.
grep -v "^#" ${result} | tr -d -c | wc -c
Now it expects 6 columns (and 5 separators) in the output, but it may
be changed later so count the field in the header first and compare it
to the actual output lines.
$ cat ${result}
# output: contended, total wait, max wait, avg wait, type, caller

cxl for v6.5
- 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
topology) error handling.
- Rework CPU cache management with respect to region configuration
(device hotplug or other dynamic changes to memory interleaving)
- Fix region reconfiguration vs CXL decoder ordering rules.

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
topology) error handling.
- Rework CPU cache management with respect to region configuration
(device hotplug or other dynamic changes to memory interleaving)
- Fix region reconfiguration vs CXL decoder ordering rules"

selftests: Test RISC-V Vector's first-use handler
This add a test to check if the kernel zero-initializes all V registers after the first-use trap handler returns. If V registers are not zero-initialized, then the test should fail one out of several runs: ``` root@sifive-fpga:~# ./v_initval_nolibc # vl = 256 not ok 1 detect stale values on v-regesters 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 4c 41 4e 47 3d 43 0 50 41 54 48 3d 2f 75 73 72 2f 6c 6f 63 61 6c 2f 73 62 69 6e 3a 2f 75 73 72 2f 6c 6f 63 61 6c 2f 62 69 6e 3a 2f 75 73 72 ff ff 81 0 0 0 0 0 0 0 0 0 0 0 0 0 ``` Otherwise, the test passes without errors each run.

perf tools changes and fixes for v6.5: 1st batch
Internal cleanup:
- Refactor PMU data management to handle hybrid systems in a generic way.
Do more work in the lexer so that legacy event types parse more easily.
A side-effect of this is that if a PMU is specified, scanning sysfs is
avoided improving start-up time.
- Fix hybrid metrics, for example, the TopdownL1 works for both performance
and efficiency cores on Intel machines. To support this, sort and regroup
events after parsing.
- Add reference count checking for the 'thread' data structure.
- Lots of fixes for memory leaks in various places thanks to the ASAN and
Ian's refcount checker.
- Reduce the binary size by replacing static variables with local or
dynamically allocated memory.
- Introduce shared_mutex for annotate data to reduce memory footprint.
- Make filesystem access library functions more thread safe.
Test:
- Organize cpu_map tests into a single suite.
- Add metric value validation test to check if the values are within correct
value ranges.
- Add perf stat stdio output test to check if event and metric names match.
- Add perf data converter JSON output test.
- Fix a lot of issues reported by shellcheck(1). This is a preparation to
enable shellcheck by default.
- Make the large x86 new instructions test optional at build time using
EXTRA_TESTS=1.
- Add a test for libpfm4 events.
perf script:
- Add 'dsoff' outpuf field to display offset from the DSO.
$ perf script -F comm,pid,event,ip,dsoff

Pull perf tools updates from Namhyung Kim:
"Internal cleanup:
- Refactor PMU data management to handle hybrid systems in a generic
way.
Do more work in the lexer so that legacy event types parse more
easily. A side-effect of this is that if a PMU is specified,
scanning sysfs is avoided improving start-up time.
- Fix hybrid metrics, for example, the TopdownL1 works for both
performance and efficiency cores on Intel machines. To support
this, sort and regroup events after parsing.
- Add reference count checking for the 'thread' data structure.
- Lots of fixes for memory leaks in various places thanks to the ASAN
and Ian's refcount checker.
- Reduce the binary size by replacing static variables with local or
dynamically allocated memory.
- Introduce shared_mutex for annotate data to reduce memory
footprint.
- Make filesystem access library functions more thread safe.
Test:
- Organize cpu_map tests into a single suite.
- Add metric value validation test to check if the values are within
correct value ranges.
- Add perf stat stdio output test to check if event and metric names
match.
- Add perf data converter JSON output test.
- Fix a lot of issues reported by shellcheck(1). This is a
preparation to enable shellcheck by default.
- Make the large x86 new instructions test optional at build time
using EXTRA_TESTS=1.
- Add a test for libpfm4 events.
perf script:
- Add 'dsoff' outpuf field to display offset from the DSO.
$ perf script -F comm,pid,event,ip,dsoff

Probes updates for v6.5:
- fprobe: Pass return address to the fprobe entry/exit callbacks so that
the callbacks don't need to analyze pt_regs/stack to find the function
return address.
- kprobe events: cleanup usage of TPARG_FL_FENTRY and TPARG_FL_RETURN
flags so that those are not set at once.
- fprobe events:
. Add a new fprobe events for tracing arbitrary function entry and
exit as a trace event.
. Add a new tracepoint events for tracing raw tracepoint as a trace
event. This allows user to trace non user-exposed tracepoints.
. Move eprobe's event parser code into probe event common file.
. Introduce BTF (BPF type format) support to kernel probe (kprobe,
fprobe and tracepoint probe) events so that user can specify traced
function arguments by name. This also applies the type of argument
when fetching the argument.
. Introduce '$arg*' wildcard support if BTF is available. This expands
the '$arg*' meta argument to all function argument automatically.
. Check the return value types by BTF. If the function returns 'void',
'$retval' is rejected.
. Add some selftest script for fprobe events, tracepoint events and
BTF support.
. Update documentation about the fprobe events.
. Some fixes for above features, document and selftests.
- selftests for ftrace (except for new fprobe events):
. Add a test case for multiple consecutive probes in a function which
checks if ftrace based kprobe, optimized kprobe and normal kprobe
can be defined in the same target function.
. Add a test case for optimized probe, which checks whether kprobe
can be optimized or not.

Tracing updates for 6.5:
- Add new feature to have function graph tracer record the return value. Adds a new option: funcgraph-retval ; when set, will show the return value of a function in the function graph tracer. - Also add the option: funcgraph-retval-hex where if it is not set, and the return value is an error code, then it will return the decimal of the error code, otherwise it still reports the hex value. - Add the file /sys/kernel/tracing/osnoise/per_cpu/cpu<cpu>/timerlat_fd That when a application opens it, it becomes the task that the timer lat tracer traces. The application can also read this file to find out how it's being interrupted. - Add the file /sys/kernel/tracing/available_filter_functions_addrs that works just the same as available_filter_functions but also shows the addresses of the functions like kallsyms, except that it gives the address of where the fentry/mcount jump/nop is.

- Make ELFv2 ABI the default for 64-bit big-endian kernel builds, and use
the -mprofile-kernel option (kernel specific ftrace ABI) for big endian
ELFv2 kernels.
- Add initial Dynamic Execution Control Register (DEXCR) support, and allow
the ROP protection instructions to be used on Power 10.
- Various other small features and fixes.

perf tools: Do not remove addr_location.thread in thread__find_map()
The thread__find_map() is to find a map for a given address in the
given thread's address space. It searches maps based on the cpu mode
and fills various information in the addr_location data structure.
It might change al->maps and al->map, but not al->thread. Then I
think no reason to not set the al->thread at the beginning.
Also get rid of the duplicate 'al->map = NULL' part.

tracing: Fix user event write on buffer disabled
The user events write currently returns the size of what was suppose to be written when tracing is disabled and nothing was written. Instead, behave like trace_marker and return -EBADF, as that is what is returned if a file is opened for read only, and a write is performed on it. Writing to the buffer that is disabled is like trying to write to a file opened for read only, as the buffer still can be read, but just not written to.

sound updates for 6.5-rc1
Lots of changes as usual, but the only significant stuff in ALSA core
part is the MIDI 2.0 support, while ASoC core kept receiving the code
refactoring. The majority of changes are seen rather in device
drivers, and quite a few new drivers can be found there.
Here we go, some highlights:
ALSA and ASoC Core:
- Support of MIDI 2.0 devices: rawmidi and sequencer API have been
extended for the support of the new UMP (Universal MIDI Packet)
protocol, USB audio driver got the USB MIDI 2.0 interface support
- Continued refactoring around ASoC DAI links and the ordering of
trigger callbacks
- PCM ABI extension for better drain support
ASoC Drivers:
- Conversions of many drivers to use maple tree based caches
- Everlasting improvement works on ASoC Intel drivers
- Compressed audio support for Qualcomm
- Support for AMD SoundWire, Analog Devices SSM3515, Google Chameleon,
Ingenic X1000, Intel systems with various CODECs, Loongson
platforms, Maxim MAX98388, Mediatek MT8188, Nuvoton NAU8825C, NXP
platforms with NAU8822, Qualcomm WSA884x, StarFive JH7110, Texas
Instruments TAS2781
HD-audio:
- Quirks for HP and ASUS machines
- CS35L41 HD-audio codec fixes
- Loongson HD-audio support
Misc:
- A new virtual PCM test driver for kselftests
- Continued refactoring and improvements on the legacy emu10k1 driver

Merge tag 'gpio-updates-for-v6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux
Pull gpio updates from Bartosz Golaszewski:
"We have two new drivers, some improvements to the core code, lots of
different updates to existing GPIO drivers and some dt-bindings on
top.
There's nothing controversial in here and almost everything has been
in next for more than a week (95% a lot longer than this). The only
thing that has spent less time in next is a new driver so no risk of
regressions.
The single merge pulls in changes that remove all usage of global GPIO
numbers from arch/arm/mach-omap.
Core GPIO library:
- remove unused symbols
- don't spam the kernel log with messages about hogs
- remove old sysfs API cruft
- improve handling of GPIO masks
New drivers:
- add a driver for the BlueField-3 GPIO controller
- add GPIO support for the TPS65219 PMIC
Driver improvements:
- extend the gpio-aggregator driver to support ramp-up/ramp-down
delay
- remove unnecessary CONFIG_OF guards from gpio-aggregator
- readability improvements in gpio-tangier
- switch i2c drivers back to using probe() now that it's been
converted in the i2c subsystem to not taking the id parameter
- remove unused inclusions of of_gpio.h in several drivers
- make pm ops static in gpio-davinci and fix a comment
- use more devres in drivers to shrink and simplify the code
- add missing include in gpio-sa1100
- add HAS_IOPORT KConfig dependency where needed
- add permissions checks before accessing pins in gpio-tegra186
- convert the gpio-zynq driver to using immutable irqchips
- preserve output settings set by the bootloader in gpio-mpc8xxx
Selftests:
- tweak the variable naming in script tests
Device tree updates:
- convert gpio-mmio and gpio-stmpe to YAML
- add parsing of GPIO hogs to gpio-vf610
- add bindings for the Cirrus EP93xx GPIO controller
- add gpio-line-names property to the gpio-pca9570 bindings
- extend the binding for x-powers,axp209 with another block"

Networking changes for 6.5.
Core
----
- Rework the sendpage & splice implementations. Instead of feeding
data into sockets page by page extend sendmsg handlers to support
taking a reference on the data, controlled by a new flag called
MSG_SPLICE_PAGES. Rework the handling of unexpected-end-of-file
to invoke an additional callback instead of trying to predict what
the right combination of MORE/NOTLAST flags is.
Remove the MSG_SENDPAGE_NOTLAST flag completely.
- Implement SCM_PIDFD, a new type of CMSG type analogous to
SCM_CREDENTIALS, but it contains pidfd instead of plain pid.
- Enable socket busy polling with CONFIG_RT.
- Improve reliability and efficiency of reporting for ref_tracker.
- Auto-generate a user space C library for various Netlink families.
Protocols
---------
- Allow TCP to shrink the advertised window when necessary, prevent
sk_rcvbuf auto-tuning from growing the window all the way up to
tcp_rmem[2].
- Use per-VMA locking for "page-flipping" TCP receive zerocopy.
- Prepare TCP for device-to-device data transfers, by making sure
that payloads are always attached to skbs as page frags.
- Make the backoff time for the first N TCP SYN retransmissions
linear. Exponential backoff is unnecessarily conservative.
- Create a new MPTCP getsockopt to retrieve all info (MPTCP_FULL_INFO).
- Avoid waking up applications using TLS sockets until we have
a full record.
- Allow using kernel memory for protocol ioctl callbacks, paving
the way to issuing ioctls over io_uring.
- Add nolocalbypass option to VxLAN, forcing packets to be fully
encapsulated even if they are destined for a local IP address.
- Make TCPv4 use consistent hash in TIME_WAIT and SYN_RECV. Ensure
in-kernel ECMP implementation (e.g. Open vSwitch) select the same
link for all packets. Support L4 symmetric hashing in Open vSwitch.
- PPPoE: make number of hash bits configurable.
- Allow DNS to be overwritten by DHCPACK in the in-kernel DHCP client
(ipconfig).
- Add layer 2 miss indication and filtering, allowing higher layers
(e.g. ACL filters) to make forwarding decisions based on whether
packet matched forwarding state in lower devices (bridge).
- Support matching on Connectivity Fault Management (CFM) packets.
- Hide the "link becomes ready" IPv6 messages by demoting their
printk level to debug.
- HSR: don't enable promiscuous mode if device offloads the proto.
- Support active scanning in IEEE 802.15.4.
- Continue work on Multi-Link Operation for WiFi 7.
BPF
---
- Add precision propagation for subprogs and callbacks. This allows
maintaining verification efficiency when subprograms are used,
or in fact passing the verifier at all for complex programs,
especially those using open-coded iterators.
- Improve BPF's {g,s}setsockopt() length handling. Previously BPF
assumed the length is always equal to the amount of written data.
But some protos allow passing a NULL buffer to discover what
the output buffer *should* be, without writing anything.
- Accept dynptr memory as memory arguments passed to helpers.
- Add routing table ID to bpf_fib_lookup BPF helper.
- Support O_PATH FDs in BPF_OBJ_PIN and BPF_OBJ_GET commands.
- Drop bpf_capable() check in BPF_MAP_FREEZE command (used to mark
maps as read-only).
- Show target_{obj,btf}_id in tracing link fdinfo.
- Addition of several new kfuncs (most of the names are self-explanatory):
- Add a set of new dynptr kfuncs: bpf_dynptr_adjust(),
bpf_dynptr_is_null(), bpf_dynptr_is_rdonly(), bpf_dynptr_size()
and bpf_dynptr_clone().
- bpf_task_under_cgroup()
- bpf_sock_destroy() - force closing sockets
- bpf_cpumask_first_and(), rework bpf_cpumask_any*() kfuncs
Netfilter
---------
- Relax set/map validation checks in nf_tables. Allow checking
presence of an entry in a map without using the value.
- Increase ip_vs_conn_tab_bits range for 64BIT builds.
- Allow updating size of a set.
- Improve NAT tuple selection when connection is closing.
Driver API
----------
- Integrate netdev with LED subsystem, to allow configuring HW
"offloaded" blinking of LEDs based on link state and activity
(i.e. packets coming in and out).
- Support configuring rate selection pins of SFP modules.
- Factor Clause 73 auto-negotiation code out of the drivers, provide
common helper routines.
- Add more fool-proof helpers for managing lifetime of MDIO devices
associated with the PCS layer.
- Allow drivers to report advanced statistics related to Time Aware
scheduler offload (taprio).
- Allow opting out of VF statistics in link dump, to allow more VFs
to fit into the message.
- Split devlink instance and devlink port operations.

v6.5-rc1-sysctl-next
The changes queued up for v6.5-rc1 for sysctl are in line with prior efforts to stop usage of deprecated routines which incur recursion and also make it hard to remove the empty array element in each sysctl array declaration. The most difficult user to modify was parport which required a bit of re-thinking of how to declare shared sysctls there, Joel Granados has stepped up to the plate to do most of this work and eventual removal of register_sysctl_table(). That work ended up saving us about 1465 bytes according to bloat-o-meter. Since we gained a few bloat-o-meter karma points I moved two rather small sysctl arrays from kernel/sysctl.c leaving us only two more sysctl arrays to move left. Most changes have been tested on linux-next for about a month. The last straggler patches are a minor parport fix, changes to the sysctl kernel selftest so to verify correctness and prevent regressions for the future change he made to provide an alternative solution for the special sysctl mount point target which was using the now deprecated sysctl child element. This is all prep work to now finally be able to remove the empty array element in all sysctl declarations / registrations which is expected to save us a bit of bytes all over the kernel. That work will be tested early after v6.5-rc1 is out. -----BEGIN PGP SIGNATURE----- iQJGBAABCgAwFiEENnNq2KuOejlQLZofziMdCjCSiKcFAmSceh0SHG1jZ3JvZkBr ZXJuZWwub3JnAAoJEM4jHQowkoinBFQQAK9WdpcU8ODoDzoSls4jsCQpZUCfZ+ED pbCgQqUqu9VPs6bnJ+aXVa6Fh3uCr6+TIfNFM55qI/Sbo2issZ7bm0nvKmGgc6/m giqDP7btvHqiAsEootci8DVdbBXKkdH4dx3pSwleyN8pdinewH0hrKImaPpahyo6 1mB1du0iI89yjsZmheHVVSyfXXYAnP0PqRVy5Y+qxY7yYlIegQ5uAZmwRE62lfTf TuiV7OFuDZ2DBYOmqIhfGKGRnfOL5ZVF3iHCrfUpX3p+fEFzDmwvm3vr73PTSrFw /aRRLa/hOWr5ilw1bvnMcazgQzFEOlQb3DMhBKH7gLl3XHVrM+TaaqYHjUia1+6Y e2axz/duA2q9uLMW81daRApvHMCgy0exkpC7prfOxF5bgTe4TjA7ZWvGpqG1kPKT PPSxw80XvG5hLZm4tB0ZWJ5rOfFpiUGGneSeRQwyuClBt73SIO+F03jyGpt83slU jFE50ac14Zwh1oxpCQtYoR1+bXWdq1QwM5vQBNEuaoTSnJfVjrXqBz/BnqJChtjr m1vA27+4/dfki2P3gVWF1lGx43ir3uJvqk+BjWXm2CDDJqpRi3N0qcUwZwLuqAAz /LEgFqK61bpHi/C8c2NWAxIoeWRU4NUOaoiKmZwyt0sKAWU1Yzg70xssYeg7VYqZ 3pvFNVBqkV+F =sXUU -----END PGP SIGNATURE----- Merge tag 'v6.5-rc1-sysctl-next' of git://git.kernel.org/pub/scm/linux/kernel/git/mcgrof/linux Pull sysctl updates from Luis Chamberlain: "The changes for sysctl are in line with prior efforts to stop usage of deprecated routines which incur recursion and also make it hard to remove the empty array element in each sysctl array declaration.

Most changes have been tested on linux-next for about a month. The last straggler patches are a minor parport fix, changes to the sysctl kernel selftest so to verify correctness and prevent regressions for the future change he made to provide an alternative solution for the special sysctl mount point target which was using the now deprecated sysctl child element. This is all prep work to now finally be able to remove the empty array element in all sysctl declarations / registrations which is expected to save us a bit of bytes all over the kernel.

v6.5-rc1-modules-next
The changes queued up for v6.5-rc1 for modules are pretty tame, mostly code removal of moving of code. Only two minor functional changes are made, the only one which stands out is Sebastian Andrzej Siewior's simplification of module reference counting by removing preempt_disable() and that has been tested on linux-next for well over a month without no regressions. I'm now, I guess, also a kitchen sink for some kallsyms changes. -----BEGIN PGP SIGNATURE----- iQJGBAABCgAwFiEENnNq2KuOejlQLZofziMdCjCSiKcFAmScfl0SHG1jZ3JvZkBr ZXJuZWwub3JnAAoJEM4jHQowkoin8oMP/0DQK+r3BZimknzz6rF0EBStNZ/dIK2W 1Q/r/ER4VKQKYxklc1M74K+7IX8ZDCYxqlaDS9lvAkRDWNC+t69aNZEib2odJleC p6WB30P0JIwfZZC0DS/ct3vrWZTyUhw7aOtvABRmjBfiJ3lFlU092Glvk1w1aFbD UrNRomPu4CujzfmnGj3VGc+HVSOEK0F1/GLm9ClrsR8SzKEpQmH4ALI/ON69B0ea PmL+d1Wyt6WEoH0hlV1TOXNdHUb3ZO1riSSfDYQ7TiG2AM5w1t4n26YRusc16hYU 6Bx4OGt52ZJYR3btsRQlcylF4R5DUo+boDkM0NqEDU/3ciGMg6DgKdHnYCBN1w+X ZO8aXK1MIgF7W6CqSz+8HCsu5CuCos55FgM22dPbpZr3OEFCWemqnV+cYCu1DA+M Gbnn883ZLtt+R+qikD3135s+LxYIvxSuQrj+B3ZoQeIKEtAlyxuhrUJbU0tOns0j 05PrkI8J1FtIysdlNZeIFg752IPtjp/0QNB4R46m40mT16L0TSjEP7c+zcPDryMb 84SdLqh1gis0QZRkoH6JbMBDeT2dtuxqtQ5dTPka4s1mtg3SvRYr53sCJg+gQ8e2 CBW6jgrIf3F4RIMMiSfXpSf4yVVxXxJAEFnGLRXhQ2HkUnk3mdGEfsZc7ucrsnlK f/KwaEzmLD9c =gjKD -----END PGP SIGNATURE----- Merge tag 'v6.5-rc1-modules-next' of git://git.kernel.org/pub/scm/linux/kernel/git/mcgrof/linux Pull module updates from Luis Chamberlain: "The changes queued up for modules are pretty tame, mostly code removal of moving of code.

spi: Updates for v6.5
One small core feature this time around but mostly driver improvements
and additions for SPI:
- Add support for controlling the idle state of MOSI, some systems can
support this and depending on the system integration may need it to
avoid glitching in some situations.
- Support for polling mode in the S3C64xx driver and DMA on the
Qualcomm QSPI driver.
- Support for several Allwinner SoCs, AMD Pensando Elba, Intel Mount
Evans, Renesas RZ/V2M, and ST STM32H7.

objtool changes for v6.5:
- Build footprint & performance improvements:
- Reduce memory usage with CONFIG_DEBUG_INFO=y
In the worst case of an allyesconfig+CONFIG_DEBUG_INFO=y kernel, DWARF
creates almost 200 million relocations, ballooning objtool's peak heap
usage to 53GB. These patches reduce that to 25GB.
On a distro-type kernel with kernel IBT enabled, they reduce objtool's
peak heap usage from 4.2GB to 2.8GB.
These changes also improve the runtime significantly.
- Debuggability improvements:
- Add the unwind_debug command-line option, for more extend unwinding
debugging output.
- Limit unreachable warnings to once per function
- Add verbose option for disassembling affected functions
- Include backtrace in verbose mode
- Detect missing __noreturn annotations
- Ignore exc_double_fault() __noreturn warnings
- Remove superfluous global_noreturns entries
- Move noreturn function list to separate file
- Add __kunit_abort() to noreturns
- Unwinder improvements:
- Allow stack operations in UNWIND_HINT_UNDEFINED regions
- drm/vmwgfx: Add unwind hints around RBP clobber
- Cleanups:
- Move the x86 entry thunk restore code into thunk functions
- x86/unwind/orc: Use swap() instead of open coding it
- Remove unnecessary/unused variables
- Fixes for modern stack canary handling

On a distro-type kernel with kernel IBT enabled, they reduce
objtool's peak heap usage from 4.2GB to 2.8GB.
These changes also improve the runtime significantly.
Debuggability improvements:
- Add the unwind_debug command-line option, for more extend unwinding
debugging output
- Limit unreachable warnings to once per function
- Add verbose option for disassembling affected functions
- Include backtrace in verbose mode
- Detect missing __noreturn annotations
- Ignore exc_double_fault() __noreturn warnings
- Remove superfluous global_noreturns entries
- Move noreturn function list to separate file
- Add __kunit_abort() to noreturns
Unwinder improvements:
- Allow stack operations in UNWIND_HINT_UNDEFINED regions
- drm/vmwgfx: Add unwind hints around RBP clobber
Cleanups:
- Move the x86 entry thunk restore code into thunk functions
- x86/unwind/orc: Use swap() instead of open coding it
- Remove unnecessary/unused variables

perf pmu: Correct auto_merge_stats test
The original logic was to check is_pmu_hybrid() like in the below.
It just checks the name of PMU specifically for Intel hybrid systems
which means uncore PMU events should return false.
https://lore.kernel.org/all/20230527072210.2900565-35-irogers@google.com/
The is_pmu_hybrid() was replaced by arch-agnostic way but with the
incorrect condition which was fixed for core PMUs but not uncore.
This change fixes both.

RCU pull request for v6.5

fixes.2023.05.11a: Miscellaneous fixes, perhaps most notably:
o Remove RCU_NONIDLE(). The new visibility of most of the idle
loop to RCU has obsoleted this API.
o Make the RCU_SOFTIRQ callback-invocation time limit also apply
to the rcuc kthreads that invoke callbacks for CONFIG_PREEMPT_RT.
o Add a jiffies-based callback-invocation time limit to handle
long-running callbacks. (The local_clock() function is only
invoked once per 32 callbacks due to its high overhead.)
o Stop rcu_tasks_invoke_cbs() from using never-onlined CPUs,
which fixes a bug that can occur on systems with non-contiguous
CPU numbering.
kvfree.2023.05.10a: kvfree_rcu updates
o Eliminate the single-argument variant of k[v]free_rcu() now
that all uses have been converted to k[v]free_rcu_mightsleep().
o Add WARN_ON_ONCE() checks for k[v]free_rcu*() freeing callbacks
too soon. Yes, this is closing the barn door after the horse
has escaped, but Murphy says that there will be more horses.

Pull btrfs updates from David Sterba:
"Mainly core changes, refactoring and optimizations.
Performance is improved in some areas, overall there may be a
cumulative improvement due to refactoring that removed lookups in the
IO path or simplified IO submission tracking.
Core:
- submit IO synchronously for fast checksums (crc32c and xxhash),
remove high priority worker kthread
- read extent buffer in one go, simplify IO tracking, bio submission
and locking
- remove additional tracking of redirtied extent buffers, originally
added for zoned mode but actually not needed
- track ordered extent pointer in bio to avoid rbtree lookups during
IO
- scrub, use recovered data stripes as cache to avoid unnecessary
read
- in zoned mode, optimize logical to physical mappings of extents
- remove PageError handling, not set by VFS nor writeback
- cleanups, refactoring, better structure packing
- lots of error handling improvements
- more assertions, lockdep annotations
- print assertion failure with the exact line where it happens
- tracepoint updates
- more debugging prints
Performance:
- speedup in fsync(), better tracking of inode logged status can
avoid transaction commit
- IO path structures track logical offsets in data structures and
does not need to look it up
User visible changes:
- don't commit transaction for every created subvolume, this can
reduce time when many subvolumes are created in a batch
- print affected files when relocation fails
- trigger orphan file cleanup during START_SYNC ioctl
Notable fixes:
- fix crash when disabling quota and relocation
- fix crashes when removing roots from drity list
- fix transacion abort during relocation when converting from newer
profiles not covered by fallback
- in zoned mode, stop reclaiming block groups if filesystem becomes
read-only
- fix rare race condition in tree mod log rewind that can miss some
btree node slots
- with enabled fsverity, drop up-to-date page bit in case the
verification fails"

Merge branch 'for-6.5/cxl-type-2' into for-6.5/cxl
Pick up the driver cleanups identified in preparation for CXL "type-2" (accelerator) device support. The major change here from a conflict generation perspective is the split of 'struct cxl_memdev_state' from the core 'struct cxl_dev_state'. Since an accelerator may not care about all the optional features that are standard on a CXL "type-3" (host-only memory expander) device. A silent conflict also occurs with the move of the endpoint port to be a formal property of a 'struct cxl_memdev' rather than drvdata. |

tools/testing/cxl: add firmware update emulation to CXL memdevs
Add emulation for the 'Get FW Info', 'Transfer FW', and 'Activate FW' CXL mailbox commands to the cxl_test emulated memdevs to enable end-to-end unit testing of a firmware update flow. For now, only advertise an 'offline activation' capability as that is all the CXL memdev driver currently implements. Add some canned values for the serial number fields, and create a platform device sysfs knob to calculate the sha256sum of the firmware image that was received, so a unit test can compare it with the original file that was uploaded.

cxl/mbox: Move mailbox related driver state to its own data structure
'struct cxl_dev_state' makes too many assumptions about the capabilities of a CXL device. In particular it assumes a CXL device has a mailbox and all of the infrastructure and state that comes along with that. In preparation for supporting accelerator / Type-2 devices that may not have a mailbox and in general maintain a minimal core context structure, make mailbox functionality a super-set of 'struct cxl_dev_state' with 'struct cxl_memdev_state'. With this reorganization it allows for CXL devices that support HDM decoder mapping, but not other general-expander / Type-3 capabilities, to only enable that subset without the rest of the mailbox infrastructure coming along for the ride.

cxl: Rename 'uport' to 'uport_dev'
For symmetry with the recent rename of ->dport_dev for a 'struct cxl_dport', add the "_dev" suffix to the ->uport property of a 'struct cxl_port'. These devices represent the downstream-port-device and upstream-port-device respectively in the CXL/PCIe topology.

cxl/rch: Prepare for caching the MMIO mapped PCIe AER capability
Prepare cxl_probe_rcrb() for retrieving more than just the component
register block. The RCH AER handling code wants to get back to the AER
capability that happens to be MMIO mapped rather then configuration
cycles.
Move RCRB specific downstream port data, like the RCRB base and the
AER capability offset, into its own data structure ('struct
cxl_rcrb_info') for cxl_probe_rcrb() to fill. Extend 'struct
cxl_dport' to include a 'struct cxl_rcrb_info' attribute.
This centralizes all RCRB scanning in one routine.

cxl/acpi: Probe RCRB later during RCH downstream port creation
The RCRB is extracted already during ACPI CEDT table parsing while the data of this is needed not earlier than dport creation. This implementation comes with drawbacks: During ACPI table scan there is already MMIO access including mapping and unmapping, but only ACPI data should be collected here. The collected data must be transferred through a couple of interfaces until it is finally consumed when creating the dport. This causes complex data structures and function interfaces. Additionally, RCRB parsing will be extended to also extract AER data, it would be much easier do this at a later point during port and dport creation when the data structures are available to hold that data. To simplify all that, probe the RCRB at a later point during RCH downstream port creation. Change ACPI table parser to only extract the base address of either the component registers or the RCRB. Parse and extract the RCRB in devm_cxl_add_rch_dport(). This is in preparation to centralize all RCRB scanning.

net: Kill MSG_SENDPAGE_NOTLAST
Now that ->sendpage() has been removed, MSG_SENDPAGE_NOTLAST can be cleaned up. Things were converted to use MSG_MORE instead, but the protocol sendpage stubs still convert MSG_SENDPAGE_NOTLAST to MSG_MORE, which is now unnecessary.

selftests: mptcp: drop sflags parameter
run_tests() accepts too many optional parameters. Before this modification,
it was required to set all of then when only the last one had to be
changed. That's not clear to see all these 0 and it makes the maintenance
harder:
run_tests $ns1 $ns2 10.0.1.1 1 2 3 slow
Instead, the parameter can be set as an env var with a limited scope:
foo=1 bar=2 next=3 \
run_tests $ns1 $ns2 10.0.1.1 slow
This patch switches to key/value "sflags=*" instead of positional parameter
sflags of do_transfer() and run_tests().
