perf stat: Fix forked applications enablement of counters
I have run into the following issue:
# perf stat -a -e new_pmu/INSTRUCTION_7/ -- mytest -c1 7
Performance counter stats for 'system wide':
0 new_pmu/INSTRUCTION_7/
0.000366428 seconds time elapsed
#
The new PMU for s390 counts the execution of certain CPU instructions.
The root cause is the extremely small run time of the mytest program. It
just executes some assembly instructions and then exits.
In above invocation the instruction is executed exactly one time (-c1
option). The PMU is expected to report this one time execution by a
counter value of one, but fails to do so in some cases, not all.
Debugging reveals the invocation of the child process is done
*before* the counter events are installed and enabled.
Tracing reveals that sometimes the child process starts and exits before
the event is installed on all CPUs. The more CPUs the machine has, the
more often this miscount happens.
Fix this by reversing the start of the work load after the events have
been installed on the specified CPUs. Now the comment also matches the
code.
Output after:
# perf stat -a -e new_pmu/INSTRUCTION_7/ -- mytest -c1 7
Performance counter stats for 'system wide':
1 new_pmu/INSTRUCTION_7/
0.000366428 seconds time elapsed
#
Now the correct result is reported rock solid all the time regardless
how many CPUs are online.
Reviewers notes:
Jiri:
Right, without -a the event has enable_on_exec so the race does not
matter, but it's a problem for system wide with fork.
Namhyung:
Agreed. Also we may move the enable_counters() and the clock code out of
the if block to be shared with the else block.

perf evsel: Make evsel__env() always return a valid env
It's possible to have an evsel and evsel->evlist populated without
an evsel->evlist->env, when, e.g., cmd_record is in its error path.
Future patches will add support for evsel__open_strerror to be able
to customize error messaging based on perf_env__{arch,cpuid}, so
let's have evsel__env return &perf_env instead of NULL in that case.

perf script: Add 'brstackinsnlen' for branch stacks
When analyzing with 'perf script', it's useful to understand the
captured instruction and the next sequential instruction.
To calculate the address of the next sequential instruction, the length
of the captured instruction is required.
For example, you can’t know the next sequential instruction after an
unconditional branch unless you calculate that based on its length.
For branch stacks, 'perf script' only prints the instruction bytes with
'brstackinsn', but lacks the instruction length.
Add 'brstackinsnlen' to print the instruction length.
$ perf script -F ip,brstackinsn,brstackinsnlen --xed

perf parse-events: Move slots only with topdown
If slots isn't with a topdown event then moving it is unnecessary. For
example {instructions, slots} is re-ordered:
$ perf stat -e '{instructions,slots}' -a sleep 1
Performance counter stats for 'system wide':
936,600,825 slots
144,440,968 instructions
1.006061423 seconds time elapsed
Which can break tools expecting the command line order to match the
printed order. It is necessary to move the slots event first when it
appears with topdown events. Add extra checking so that the slots event
is only moved in the case of there being a topdown event like:
$ perf stat -e '{instructions,slots,topdown-fe-bound}' -a sleep 1
Performance counter stats for 'system wide':
2427568570 slots
300927614 instructions
551021649 topdown-fe-bound
1.001771803 seconds time elapsed

perf tools: Fix version kernel tag
Generating the version kernel tag relies on "git describe" command to
get the latest Linus kernel tag.
However, when working from clones of Linus' git we may not have the latest
tag. For example, when working on Arnaldo's acme.git, we can have this:
$ git branch
perf/core
$ head -n 5 ../../Makefile | tail -n 4
VERSION = 5
PATCHLEVEL = 17
SUBLEVEL = 0
EXTRAVERSION = -rc3
$ git describe --abbrev=0 --match "v[0-9].[0-9]*"
v4.13-rc5
Indeed using tags is a problem as it relies on tags being pulled from
Linus' git (and pushed to the clone).

Merge tag 'for-5.18-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux
Pull btrfs updates from David Sterba:
"This contains feature updates, performance improvements, preparatory
and core work and some related VFS updates:
Features:
- encoded read/write ioctls, allows user space to read or write raw
data directly to extents (now compressed, encrypted in the future),
will be used by send/receive v2 where it saves processing time
- zoned mode now works with metadata DUP (the mkfs.btrfs default)
- error message header updates:
- print error state: transaction abort, other error, log tree
errors
- print transient filesystem state: remount, device replace,
ignored checksum verifications
- tree-checker: verify the transaction id of the to-be-written dirty
extent buffer
Performance improvements for fsync:
- directory logging speedups (up to -90% run time)
- avoid logging all directory changes during renames (up to -60% run
time)
- avoid inode logging during rename and link when possible (up to
-60% run time)
- prepare extents to be logged before locking a log tree path
(throughput +7%)
- stop copying old file extents when doing a full fsync()
- improved logging of old extents after truncate
Core, fixes:
- improved stale device identification by dev_t and not just path
(for devices that are behind other layers like device mapper)
- continued extent tree v2 preparatory work
- disable features that won't work yet
- add wrappers and abstractions for new tree roots
- improved error handling
- add super block write annotations around background block group
reclaim
- fix device scanning messages potentially accessing stale pointer
- cleanups and refactoring
VFS:
- allow reflinks/deduplication from two different mounts of the same
filesystem
- export and add helpers for read/write range verification, for the
encoded ioctls"
* tag 'for-5.18-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux: (98 commits)

f2fs-for-5.18
In this cycle, f2fs has some performance improvements for Android workloads such
as using read-unfair rwsems and adding some sysfs entries to control GCs and
discard commands in more details. In addtiion, it has some tunings to improve
the recovery speed after sudden power-cut.
Enhancement:
- add reader-unfair rwsems with F2FS_UNFAIR_RWSEM
: will replace with generic API support
- adjust to make the readahead/recovery flow more efficiently
- sysfs entries to control issue speeds of GCs and Discard commands
- enable idmapped mounts
Bug fix:
- correct wrong error handling routines
- fix missing conditions in quota
- fix a potential deadlock between writeback and block plug routines
- fix a deadlock btween freezefs and evict_inode
We've added some boundary checks to avoid kernel panics on corrupted images,
and several minor code clean-ups.

fscrypt updates for 5.18
Add support for direct I/O on encrypted files when blk-crypto (inline encryption) is being used for file contents encryption. There will be a merge conflict with the block pull request in fs/iomap/direct-io.c, due to some bio interface cleanups. The merge resolution is straightforward and can be found in linux-next. -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQSacvsUNc7UX4ntmEPzXCl4vpKOKwUCYjgCfhQcZWJpZ2dlcnNA Z29vZ2xlLmNvbQAKCRDzXCl4vpKOK6vjAQDp8D8OKIyj67KjYwvyHpNy0fZhxeur RexC0nDfd9BE/AD/fV6zpCglmsuGxqxL0jmqeczKXn2y7nRFmPciCBTi/wY= =kwNd -----END PGP SIGNATURE----- Merge tag 'fscrypt-for-linus' of git://git.kernel.org/pub/scm/fs/fscrypt/fscrypt Pull fscrypt updates from Eric Biggers: "Add support for direct I/O on encrypted files when blk-crypto (inline encryption) is being used for file contents encryption" * tag 'fscrypt-for-linus' of git://git.kernel.org/pub/scm/fs/fscrypt/fscrypt: fscrypt: update documentation for direct I/O support f2fs: support direct I/O with fscrypt using blk-crypto ext4: support direct I/O with fscrypt using blk-crypto iomap: support direct I/O with fscrypt using blk-crypto fscrypt: add functions for direct I/O support |

perf tools: Fix dependency for version file creation
The version generated by perf may not be correct by just changing the head commit, like this: $ git log --pretty=format:"%H" -n 1 b5d9d4708a24ac1889a30e9aedf8af8d73102139 $ perf -v perf version 5.16.gb5d9d4708a24 $ git reset --hard HEAD^ HEAD is now at 629f520b265f $ make ... $ ./perf -v perf version 5.16.gb5d9d4708a24 The dependency to building PERF-VERSION-FILE should also include ORIG_HEAD, as this changes when changing the head commit (while HEAD does not).

- Change the AUDIT_TIME_* record generation so that they are

This should help reduce noise and ensure those records which are

Pull selinux updates from Paul Moore:
"We've got a number of SELinux patches queued up, the highlights are:
- Fixup the security_fs_context_parse_param() LSM hook so it executes
all of the LSM hook implementations unless a serious error occurs.
We also correct the SELinux hook implementation so that it returns
zero on success.
- In addition to a few SELinux mount option parsing fixes, we
simplified the parsing by moving it earlier in the process.
The logic was that it was unlikely an admin/user would use the new
mount API and not have the policy loaded before passing the SELinux
options.
- Properly fixed the LSM/SELinux/SCTP hooks with the addition of the
security_sctp_assoc_established() hook.
This work was done in conjunction with the netdev folks and should
complete the move of the SCTP labeling from the endpoints to the
associations.
- Fixed a variety of sparse warnings caused by changes in the "__rcu"
markings of some core kernel structures.
- Ensure we access the superblock's LSM security blob using the
stacking-safe accessors.
- Added the ability for the kernel to always allow FIOCLEX and
FIONCLEX if the "ioctl_skip_cloexec" policy capability is
specified.
- Various constifications improvements, type casting improvements,
additional return value checks, and dead code/parameter removal.
- Documentation fixes"

spi: Updates for v5.18
The overwhelming bulk of this pull request is a change from Uwe
Kleine-König which changes the return type of the remove() function to
void as part of some wider work he's doing to do this for all bus types,
causing updates to most SPI device drivers. The branch with that on has
been cross merged with a couple of other trees which added new SPI
drivers this cycle, I'm not expecting any build issues resulting from
the change.
Otherwise it's been a relatively quiet release with some new device
support, a few minor features and the welcome completion of the
conversion of the subsystem to use GPIO descriptors rather than numbers:
- Change return type of remove() to void.
- Completion of the conversion of SPI controller drivers to use GPIO
descriptors rather than numbers.
- Quite a few DT schema conversions.
- Support for multiple SPI devices on a bus in ACPI systems.
- Big overhaul of the PXA2xx SPI driver.
- Support for AMD AMDI0062, Intel Raptor Lake, Mediatek MT7986 and
MT8186, nVidia Tegra210 and Tegra234, Renesas RZ/V2L, Tesla FSD and
Sunplus SP7021.

regulator: Updates for v5.18
Quite a quiet release for the regulator API, mainly a few new drivers
plus a lot of fixes for the Raspberry Pi panel driver. There's also a
SPI commit in here which I managed to apply to the wrong tree and then
didn't notice until there were too many commits on top of it, sorry
about that.
- Make it easier to use the virtual consumer test driver with DT
systems.
- Substantial overhaul providing various fixes and robustness
improvements for the Raspberry Pi panel driver.
- Support for Qualcomm PMX65 and SDX65, Richtek RT5190A, and Texas

Merge tag 'random-5.18-rc1-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/crng/random
Pull random number generator updates from Jason Donenfeld:
"There have been a few important changes to the RNG's crypto, but the
intent for 5.18 has been to shore up the existing design as much as
possible with modern cryptographic functions and proven constructions,
rather than actually changing up anything fundamental to the RNG's
design.
So it's still the same old RNG at its core as before: it still counts
entropy bits, and collects from the various sources with the same
heuristics as before, and so forth. However, the cryptographic
algorithms that transform that entropic data into safe random numbers
have been modernized.
Just as important, if not more, is that the code has been cleaned up
and re-documented. As one of the first drivers in Linux, going back to
1.3.30, its general style and organization was showing its age and
becoming both a maintenance burden and an auditability impediment.
Hopefully this provides a more solid foundation to build on for the
future. I encourage you to open up the file in full, and maybe you'll
remark, "oh, that's what it's doing," and enjoy reading it. That, at
least, is the eventual goal, which this pull begins working toward.
Here's a summary of the various patches in this pull:
- /dev/urandom and /dev/random now do the same thing, per the patch
we discussed on the list. I think this is worth trying out. If it
does appear problematic, I've made sure to keep it standalone and
revertible without any conflicts.
- Fixes and cleanups for numerous integer type problems, locking
issues, and general code quality concerns.
- The input pool's LFSR has been replaced with a cryptographically
secure hash function, which has security and performance benefits
alike, and consequently allows us to count entropy bits linearly.
- The pre-init injection now uses a real hash function too, instead
of an LFSR or vanilla xor.
- The interrupt handler's fast_mix() function now uses one round of
SipHash, rather than the fake crypto that was there before.
- All additions of RDRAND and RDSEED now go through the input pool's
hash function, in part to mitigate ridiculous hypothetical CPU
backdoors, but more so to have a consistent interface for ingesting
entropy that's easy to analyze, making everything happen one way,
instead of a potpourri of different ways.
- The crng now works on per-cpu data, while also being in accordance
with the actual "fast key erasure RNG" design. This allows us to
fix several boot-time race complications associated with the prior
dynamically allocated model, eliminates much locking, and makes our
backtrack protection more robust.
- Batched entropy now erases doled out values so that it's backtrack
resistant.
- Working closely with Sebastian, the interrupt handler no longer
needs to take any locks at all, as we punt the
synchronized/expensive operations to a workqueue. This is
especially nice for PREEMPT_RT, where taking spinlocks in irq
context is problematic. It also makes the handler faster for the
rest of us.
- Also working with Sebastian, we now do the right thing on CPU
hotplug, so that we don't use stale entropy or fail to accumulate
new entropy when CPUs come back online.
- We handle virtual machines that fork / clone / snapshot, using the
"vmgenid" ACPI specification for retrieving a unique new RNG seed,
which we can use to also make WireGuard (and in the future, other
things) safe across VM forks.
- Around boot time, we now try to reseed more often if enough entropy
is available, before settling on the usual 5 minute schedule.
- Last, but certainly not least, the documentation in the file has
been updated considerably"

Pull thermal control updates from Rafael Wysocki:
"As far as new functionality is concerned, there is a new thermal
driver for the Intel Hardware Feedback Interface (HFI) along with some
intel-speed-select utility changes to support it. There are also new
DT compatible strings for a couple of platforms, and thermal zones on
some platforms will be registered as HWmon sensors now.
Apart from the above, some drivers are updated (fixes mostly) and
there is a new piece of documentation for the Intel DPTF (Dynamic
Power and Thermal Framework) sysfs interface.
Specifics:
- Add a new thermal driver for the Intel Hardware Feedback Interface
(HFI) including the HFI initialization, HFI notification interrupt
handling and sending CPU capabilities change messages to user space
via the thermal netlink interface (Ricardo Neri, Srinivas
Pandruvada, Nathan Chancellor, Randy Dunlap).
- Extend the intel-speed-select utility to handle out-of-band CPU
configuration changes and add support for the CPU capabilities
change messages sent over the thermal netlink interface by the new
HFI thermal driver to it (Srinivas Pandruvada).
- Convert the DT bindings to yaml format for the Exynos platform and
fix and update the MAINTAINERS file for this driver (Krzysztof
Kozlowski).
- Register the thermal zones as HWmon sensors for the QCom's Tsens
driver and TI thermal platforms (Dmitry Baryshkov, Romain Naour).
- Add the msm8953 compatible documentation in the bindings (Luca
Weiss).
- Add the sm8150 platform support to the QCom LMh driver's DT binding
(Thara Gopinath).
- Check the command result from the IPC command to the BPMP in the
Tegra driver (Mikko Perttunen).
- Silence the error for normal configuration where the interrupt is
optionnal in the Broadcom thermal driver (Florian Fainelli).
- Remove remaining dead code from the TI thermal driver (Yue
Haibing).
- Don't use bitmap_weight() in end_power_clamp() in the powerclamp
driver (Yury Norov).
- Update the OS policy capabilities handshake in the int340x thermal
driver (Srinivas Pandruvada).
- Increase the policies bitmap size in int340x (Srinivas Pandruvada).
- Replace acpi_bus_get_device() with acpi_fetch_acpi_dev() in the
int340x thermal driver (Rafael Wysocki).
- Check for NULL after calling kmemdup() in int340x (Jiasheng Jiang).
- Add Intel Dynamic Power and Thermal Framework (DPTF) kernel
interface documentation (Srinivas Pandruvada).
- Fix bullet list warning in the thermal documentation (Randy
Dunlap)"

platform-level _OSC handling change to make it actually take the
platform firmware response into account, some code and documentation
cleanups, and a notable update of the ACPI device enumeration

perf test arm64: Test unwinding using fame-pointer (fp) mode
Add a shell script to check that the call-graphs generated using frame pointers (--call-graph fp) are complete and not missing leaf functions: | $ perf test 88 -v | 88: Check Arm64 callgraphs are complete in fp mode : | --- start --- | test child forked, pid 8734 | + Compiling test program (/tmp/test_program.Cz3yL)... | + Recording (PID=8749)... | + Stopping perf-record... | test_program.Cz | 728 leaf | 753 parent | 76c main | test child finished with 0 | ---- end ---- | Check Arm SPE callgraphs are complete in fp mode: Ok It's supposed to work with both unwinders: | $ make # for libunwind (default) | $ make NO_LIBUNWIND=1 # for libdw Tester notes: Ran it on N1SDP and it passes, and it fails if |

RCU pull request for v5.18
This pull request contains the following branches: exp.2022.02.24a: Contains a fix for idle detection from Neeraj Upadhyay and missing access marking detected by KCSAN. fixes.2022.02.14a: Miscellaneous fixes. rcu_barrier.2022.02.08a: Reduces coupling between rcu_barrier() and CPU-hotplug operations, so that rcu_barrier() no longer needs to do cpus_read_lock(). This may also someday allow system boot to bring CPUs online concurrently. rcu-tasks.2022.02.08a: Enable more aggressive movement to per-CPU queueing when reacting to excessive lock contention due to workloads placing heavy update-side stress on RCU tasks. rt.2022.02.01b: Improvements to RCU priority boosting, including changes from Neeraj Upadhyay, Zqiang, and Alison Chaiken. torture.2022.02.01b: Various fixes improving test robustness and debug information. torturescript.2022.02.08a: Add tests for SRCU size transitions, further compress torture.sh build products, and improve debug output. -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEbK7UrM+RBIrCoViJnr8S83LZ+4wFAmIusb0THHBhdWxtY2tA a2VybmVsLm9yZwAKCRCevxLzctn7jAklD/9VXLK7crcg2YeRXUIg1IOdnancsVCV MNtTfxNYqYIis+W2UfuHKuQu2yEXF5fihdY0J9TQv0byHsprp6FIZT+i1An4Ukgd 0vyHjd/DaIKgs2txsB1DjhlatWlJUfQuBwhtNUkpYFLFwKdCI1l813bPbNlL+GiL p0ZejVMpBC5HgE6sDOtaaQSAB+AEUp+Lgr+yaG/On8hfzwWFKO8KldxhiKY9n07v SNDfKDgXB+80hx4RBVGbkuogV3s9brFULoNRXJy7Uf79DtiY09uazhhA3G0TjO34 zGwmF91dqsXDF/Uz8g4aZO0xYRXUchOrsQ5lgO/GhTVbM9I0wWlMHEk/8WHyBJkU vlXOMuwzBc9/5uwZE3rnkA4a3nkXhPQjLlCr+/I7A/7Vsv9IBW9WSlgMvUN0Qf4S XAwTnIqfErnR60a+L0+HRr5kIV5VoXcxqI/Nv0/4/BMLRubS/c7cYjOTxXNJL9SU 50pv5vty9xk3HSpuz0JAOyLf+PUT773uUQhFr5xCBSCVqbAm5WFg6hWPAgrN/tUS wstBc0wlA73rKVJxeLDQwHc/oT1zTUEzswVZITQ5zLHK0t0GbeR6QHccsdeaJyTe DisX+66A6YQrEuJmx5xUZqjYHqtYLDOBTbHA3ZwQmvjKu8ibWZ8Fg9ioURLCS4bF +FVkp/5KdcAN9w== =ljVY -----END PGP SIGNATURE----- Merge tag 'rcu.2022.03.13a' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu Pull RCU updates from Paul McKenney: - Fix idle detection (Neeraj Upadhyay) and missing access marking detected by KCSAN. - Reduce coupling between rcu_barrier() and CPU-hotplug operations, so that rcu_barrier() no longer needs to do cpus_read_lock().
