libnvdimm for 6.5
- DAX fixes and cleanups including a use after free, extra references,
and device unregistration, and a redundant variable.
- Allow the DAX fault handler to return VM_FAULT_HWPOISON
- A few libnvdimm cleanups such as making some functions and variables
static where sufficient.
- Add a few missing prototypes for wrapped functions in
tools/testing/nvdimm

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
ls 2695501 cycles: 152cc73ef4b5 (/usr/lib/x86_64-linux-gnu/ld-2.31.so+0x1c4b5)

ls 2695501 cycles: ffffffff992a6db0 ([kernel.kallsyms])
- Adjust width for large PID/TID values.
perf report:
- Robustify reading addr2line output for srcline by checking sentinel output
before the actual data and by using timeout of 1 second.
- Allow config terms (like 'name=ABC') with breakpoint events.
$ perf record -e mem:0x55feb98dd169:x/name=breakpoint/ -p 19646 -- sleep 1
perf annotate:
- Handle x86 instruction suffix like 'l' in 'movl' generally.
- Parse instruction operands properly even with a whitespace. This is needed
for llvm-objdump output.
- Support RISC-V binutils lookup using the triplet prefixes.
- Add '<' and '>' key to navigate to prev/next symbols in TUI.
- Fix instruction association and parsing for LoongArch.
perf stat:
- Add --per-cache aggregation option, optionally specify a cache level
like `--per-cache=L2`.
$ sudo perf stat --per-cache -a -e ls_dmnd_fills_from_sys.ext_cache_remote --\
taskset -c 0-15,64-79,128-143,192-207\

Merge tag 'perf-tools-for-v6.5-1-2023-06-28' of git://git.kernel.org/pub/scm/linux/kernel/git/perf/perf-tools-next
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

- Adjust width for large PID/TID values.
perf report:
- Robustify reading addr2line output for srcline by checking sentinel
output before the actual data and by using timeout of 1 second.
- Allow config terms (like 'name=ABC') with breakpoint events.
$ perf record -e mem:0x55feb98dd169:x/name=breakpoint/ -p 19646 -- sleep 1
perf annotate:
- Handle x86 instruction suffix like 'l' in 'movl' generally.
- Parse instruction operands properly even with a whitespace. This is
needed for llvm-objdump output.
- Support RISC-V binutils lookup using the triplet prefixes.
- Add '<' and '>' key to navigate to prev/next symbols in TUI.
- Fix instruction association and parsing for LoongArch.
perf stat:
- Add --per-cache aggregation option, optionally specify a cache
level like `--per-cache=L2`.
$ sudo perf stat --per-cache -a -e ls_dmnd_fills_from_sys.ext_cache_remote --\

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. This is used by BPF to make it easier to attach BPF programs to ftrace hooks. - Replace strlcpy with strscpy in the tracing boot code. -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCZJy6ixQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qnzRAPsEI2YgjaJSHnuPoGRHbrNil6pq66wY LYaLizGI4Jv9BwEAqdSdcYcMiWo1SFBAO8QxEDM++BX3zrRyVgW8ahaTNgs= =TF0C -----END PGP SIGNATURE----- Merge tag 'trace-v6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing updates from Steven Rostedt: - Add new feature to have function graph tracer record the return value.

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

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.

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.

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.

So some of the module updates were left hanging in the email ether, and I just committed them separately. It's my bad - I should have made it more clear that I expected my own patches to come through the module tree too.

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

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
This pull contains the following branches:
doc.2023.05.10a: Documentation updates
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.
nocb.2023.05.11a: Callback-offloading updates

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/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

selftests: mptcp: check subflow and addr infos
New MPTCP info are being checked in multiple places to improve the code coverage when using the userspace PM. This patch makes chk_mptcp_info() more generic to be able to check subflows, add_addr_signal and add_addr_accepted info (and even more later). New arguments are now required to get different infos from the two namespaces because some counters are specific to the client or the server.

perf symbol: Remove symbol_name_rb_node
Most perf commands want to sort symbols by name and this is done via an invasive rbtree that on 64-bit systems costs 24 bytes. Sorting the symbols in a DSO by name is optional and not done by default, however, if sorting is requested the 24 bytes is allocated for every symbol. This change removes the rbtree and uses a sorted array of symbol pointers instead (costing 8 bytes per symbol). As the array is created on demand then there are further memory savings. The complexity of sorting the array and using the rbtree are the same. To support going to the next symbol, the index of the current symbol needs to be passed around as a pair with the current symbol. This requires some API changes.

perf test: Skip metrics w/o event name in stat STD output linter
This test checks if the output of perf stat to match event names and
metrics. So it wants the output lines to have both event name and
metric. Otherwise it should skip the line.
On AMD machines, the instruction event has two metrics and they are printed
in separate lines. It makes the line without event name like below:
# perf stat -a sleep 1
Performance counter stats for 'system wide':

Also modern Intel machines have TopDown metrics which also don't have
event names.

\--> # 10.9 % tma_retiring
1.002395924 seconds time elapsed
There is a check to skip TopdownL1 and TopdownL2 specifically but it
does not cover every affected lines.
So there is another check to skip the line if it has nothing on the left
side of # sign. Well.. it seems ok but that's not enough too.
When aggregation mode (like --per-socket or --per-thread) is used, it
adds some prefix (e.g. CPU socket, task name and PID) in the output
line. So the test code ignores them to normalize result.
A problem can happen for per-thread mode when task name contains one or
more spaces. It'd only ignore the first part of the task name, and it
thinks there's something more in the line so it would not skip.
# perf stat -a --perf-thread sleep 1
...
perf-21276 # 70.2 % tma_backend_bound
perf-21276 # 3.9 % tma_bad_speculation
perf-21276 # 10.5 % tma_frontend_bound
perf-21276 # 15.3 % tma_retiring
^^^^^^^^^^
(ignored)
my task-21328 # 70.2 % tma_backend_bound
my task-21328 # 3.9 % tma_bad_speculation
my task-21328 # 10.5 % tma_frontend_bound
my task-21328 # 15.3 % tma_retiring
^^
(ignored)
So I think it should look at the metric names instead. Add skip_metric
to hold the list of names to skip. It would contain 'stalled cycles per
insn' and metrics started by 'tma_'.

perf test: Reorder event name checks in stat STD output linter
On AMD machines, the perf stat STD output test failed like below:
$ sudo ./perf test -v 98
98: perf stat STD output linter :
--- start ---
test child forked, pid 1841901
Checking STD output: no argswrong event metric.
expected 'GHz' in 108,121 stalled-cycles-frontend # 10.88% frontend cycles idle
test child finished with -1
---- end ----
perf stat STD output linter: FAILED!
This is because there are stalled-cycles-{frontend,backend} events are
used by default. The current logic checks the event_name array to find
which event it's running. But 'cycles' event comes before those stalled
cycles event and it matches first. So it tries to find 'GHz' metric
in the output (which is for the 'cycles') and fails.
Move the stalled-cycles-{frontend,backend} events before 'cycles' so
that it can find the stalled cycles events first.
Also add a space after 'no args' test name for consistency.

kselftest/arm64: Add a test case for TPIDR2 restore
Due to the fact that TPIDR2 is intended to be managed by libc we don't currently test modifying it via the signal context since that might disrupt libc's usage of it and cause instability. We can however test the opposite case with less risk, modifying TPIDR2 in a signal handler and making sure that the original value is restored after returning from the signal handler. Add a test which does this.

perf pmu: Remove a hard coded cpu PMU assumption
The property of "cpu" when it has no cpu map is true on S390 with the PMU cpum_cf. Rather than maintain a list of such PMUs, reuse the is_core test result from the caller.

perf pmus: Add notion of default PMU for JSON events
JSON events created in pmu-events.c by jevents.py may not specify a PMU they are associated with, in which case it is implied that it is the first core PMU. Care is needed to select this for regular 'cpu', s390 'cpum_cf' and ARMs many names as at the point the name is first needed the core PMUs list hasn't been initialized. Add a helper in perf_pmus to create this value, in the worst case by scanning sysfs. v2. Add missing close if fdopendir fails.

perf test: Set PERF_EXEC_PATH for script execution
The task-analyzer.py script (actually every other scripts too) requires
PERF_EXEC_PATH env to find dependent libraries and scripts. For scripts
test to run correctly, it needs to set PERF_EXEC_PATH to the perf tool
source directory.
Instead of blindly update the env, let's check the directory structure
to make sure it points to the correct location.

perf script: Initialize buffer for regs_map()
The buffer is used to save register mapping in a sample. Normally
perf samples don't have any register so the string should be empty.
But it missed to initialize the buffer when the size is 0. And it's
passed to PyUnicode_FromString() with a garbage data.
So it returns NULL due to invalid input (instead of an empty unicode
string object) which causes a segfault like below:

tools: ynl: improve the direct-include header guard logic
Przemek suggests that I shouldn't accuse GCC of witchcraft, there is a simpler explanation for why we need manual define. scripts/headers_install.sh modifies the guard, removing _UAPI. That's why including a kernel header from the tree and from /usr leads to duplicate definitions. This also solves the mystery of why I needed to include the header conditionally. I had the wrong guards for most cases but ethtool.

syscalls: Remove file path comments from headers
Source file locations for syscall definitions can change over a period of time. File paths in comments get stale and are hard to maintain long term. Also, their usefulness is questionable since it would be easier to locate a syscall definition using the SYSCALL_DEFINEx() macro. Remove all source file path comments from the syscall headers. Also, equalize the uneven line spacing (some of which is introduced due to the deletions). Signed-off-by: Sohil Mehta <sohil.mehta@intel.com> Signed-off-by: Arnd Bergmann <arnd@arndb.de> |

asm-generic: Unify uapi bitsperlong.h for arm64, riscv and loongarch
Now we specify the minimal version of GCC as 5.1 and Clang/LLVM as 11.0.0 in Documentation/process/changes.rst, __CHAR_BIT__ and __SIZEOF_LONG__ are usable, it is probably fine to unify the definition of __BITS_PER_LONG as (__CHAR_BIT__ * __SIZEOF_LONG__) in asm-generic uapi bitsperlong.h. In order to keep safe and avoid regression, only unify uapi bitsperlong.h for some archs such as arm64, riscv and loongarch which are using newer toolchains that have the definitions of __CHAR_BIT__ and __SIZEOF_LONG__.

Basically, with header files in my local host which is based on 5.12 kernel,
__always_inline is not defined and this caused compilation failure.
Since __always_inline is defined in bpf_helpers.h, let us move bpf_helpers.h
to an early position which fixed the problem.

selftests: forwarding: Fix race condition in mirror installation
When mirroring to a gretap in hardware the device expects to be programmed with the egress port and all the encapsulating headers. This requires the driver to resolve the path the packet will take in the software data path and program the device accordingly. If the path cannot be resolved (in this case because of an unresolved neighbor), then mirror installation fails until the path is resolved. This results in a race that causes the test to sometimes fail. Fix this by setting the neighbor's state to permanent in a couple of tests, so that it is always valid. Fixes: |

perf test: Add metric value validation test
Add metric value validation test to check if metric values are with in correct value ranges. There are three types of tests included: 1) positive-value test checks if all the metrics collected are non-negative; 2) single-value test checks if the list of metrics have values in given value ranges; 3) relationship test checks if multiple metrics follow a given relationship, e.g. memory_bandwidth_read + memory_bandwidth_write = memory_bandwidth_total.

selftests: mlxsw: one_armed_router: Use port MAC for bridge address
In a future patch, mlxsw will start adding RIFs to uppers of front panel port netdevices, if they have an IP address. At the time that the front panel port is enslaved to the bridge, the bridge MAC address does not have the same prefix as other interfaces in the system. On Nvidia Spectrum-1 machines all the RIFs have to have the same 38-bit MAC address prefix. Since the bridge does not obey this limitation, the RIF cannot be created, and the enslavement attempt is vetoed on the grounds of the configuration not being offloadable. The bridge eventually inherits MAC address from its first member, after the enslavement is acked. A number of (mainly VXLAN) selftests already work around the problem by setting the MAC address to whatever it will eventually be anyway. Do the same for this selftest.

Since the bridge does not obey this limitation, the RIF cannot be created, and the enslavement attempt is vetoed on the grounds of the configuration not being offloadable. The selftest itself however checks various aspects of VXLAN offloading and the bridges do not need to participate in routing traffic. The IP addresses or the RIFs are irrelevant. Fix by disabling automatic IPv6 address generation for the HW-offloaded bridges in this selftest, thus exempting them from mlxsw router attention.
