TTY / Serial driver updates for 6.14-rc1
Here is the tty/serial driver set of changes for 6.14-rc1. Nothing major in here, it was delayed a bit due to a regression found in linux-next which has now been reverted and verified that it is fixed. Other than the reverts, highlights include: - 8250 work to get the nbcon mode working (partially reverted) - altera_jtaguart minor fixes - fsl_lpuart minor updates - sh-sci driver minor updatesa - other tiny driver updates and cleanups All of these have been in linux-next for a while, and now with no reports of problems (thanks to the reverts.)

KVM/arm64 updates for 6.14
* New features:
- Support for non-protected guest in protected mode, achieving near
feature parity with the non-protected mode
- Support for the EL2 timers as part of the ongoing NV support
- Allow control of hardware tracing for nVHE/hVHE
* Improvements, fixes and cleanups:
- Massive cleanup of the debug infrastructure, making it a bit less
awkward and definitely easier to maintain. This should pave the
way for further optimisations
- Complete rewrite of pKVM's fixed-feature infrastructure, aligning
it with the rest of KVM and making the code easier to follow
- Large simplification of pKVM's memory protection infrastructure
- Better handling of RES0/RES1 fields for memory-backed system
registers
- Add a workaround for Qualcomm's Snapdragon X CPUs, which suffer
from a pretty nasty timer bug
- Small collection of cleanups and low-impact fixes

f2fs-for-6.14-rc1

NFSD 6.14 Release Notes
Jeff Layton contributed an implementation of NFSv4.2+ attribute delegation, as described here: https://www.ietf.org/archive/id/draft-ietf-nfsv4-delstid-08.html This interoperates with similar functionality introduced into the Linux NFS client in v6.11. An attribute delegation permits an NFS client to manage a file's mtime, rather than flushing dirty data to the NFS server so that the file's mtime reflects the last write, which is considerably slower. Neil Brown contributed dynamic NFSv4.1 session slot table resizing. This facility enables NFSD to increase or decrease the number of slots per NFS session depending on server memory availability. More session slots means greater parallelism. Chuck Lever fixed a long-standing latent bug where NFSv4 COMPOUND encoding screws up when crossing a page boundary in the encoding buffer. This is a zero-day bug, but hitting it is rare and depends on the NFS client implementation. The Linux NFS client does not happen to trigger this issue. A variety of bug fixes and other incremental improvements fill out the list of commits in this release. Great thanks to all contributors, reviewers, testers, and bug reporters who participated during this development cycle. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEKLLlsBKG3yQ88j7+M2qzM29mf5cFAmeVPBUACgkQM2qzM29m f5dClxAAmW4O2bOJaR8neJ54fzeFYXtFYEXRF/XbIh2KdnCy2LoywT9ux8ndzE0k 1tsjtv0g4y84IcYfrxXPRTuhh2GO2pHw5L1kGVRezJg2ODSFbpdzGtcVK7SIrs2S eijTViqdi9xRgfj1jPqRrvxC99RL3/fmCztqorAPLDFsqYAd/6ZRxZ7+IcZ2h4+J cJ0Z6Wx6eh10roacZPXweH13XJ7xWO/ublYZvQFQpK2BAKyO98aXGgLDraNt8k60 X3DZLSKkGB/eBlNeAlTtcrXec/ot6XGJPKr3b/7zhwfMi8B13RGdSmCR8SxMdRQM vCQO4G2YadU4YFS6FFIw9Wc1XDYUuYh2YgcveafjzjXbgi7NnY7rYOxtnTgBi0Xv XGjtGqpvD676gPm+8b3DcwqmWI3c/WUdtQIZ1uYRCFZdFqkVP91bySPT2aHtx2GO 4j3uEyTlypC00kyvu1oL3+tVUG/EFlJCpYvIbOwqDG2m7KWPStzpfJTD5Q9cdlEl fdgs6l82EVqe1YyjLTqajDuOcRrLYK2hlR/5STc03hQV+GpKSo5UypRejzE9WtRV zT/tyelqhj4+0EZJz4ay/8q9s2Jp+5JGVxoVvjujSuH7+Ulb3T+IDkldtMamO8Fm www2y0/fLfU2xIapMJdCoJ+ZKgel2i8RZMPIc0cIfO5ITXm+dOs= =hwXx -----END PGP SIGNATURE----- Merge tag 'nfsd-6.14' of git://git.kernel.org/pub/scm/linux/kernel/git/cel/linux Pull nfsd updates from Chuck Lever: "Jeff Layton contributed an implementation of NFSv4.2+ attribute delegation, as described here: https://www.ietf.org/archive/id/draft-ietf-nfsv4-delstid-08.html This interoperates with similar functionality introduced into the Linux NFS client in v6.11.

Char/Misc/IIO driver updates for 6.14-rc1
Here is the "big" set of char/misc/iio and other smaller driver
subsystem updates for 6.14-rc1. Loads of different things in here this
development cycle, highlights are:
- ntsync "driver" to handle Windows locking types enabling Wine to
work much better on many workloads (i.e. games). The driver
framework was in 6.13, but now it's enabled and fully working
properly. Should make many SteamOS users happy. Even comes with
tests!
- Large IIO driver updates and bugfixes
- FPGA driver updates
- Coresight driver updates
- MHI driver updates
- PPS driver updatesa
- const bin_attribute reworking for many drivers
- binder driver updates
- smaller driver updates and fixes
All of these have been in linux-next for a while with no reported
issues.

pwm: Two fixes for the pwm core and the pwm-microchip-core driver
Conor Dooley found and fixed a problem in the pwm-microchip-core driver that existed since the driver's birth in v6.5-rc1. It's about a corner case that only happens if two pwm devices of the same chip are set to the same long period. The other problem is about the new pwm API that currently is only supported by two hardware drivers. The fix prevents a NULL pointer exception if one of the new functions is called for a pwm device with a driver that only provides the old callbacks. -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEP4GsaTp6HlmJrf7Tj4D7WH0S/k4FAmeXs+8ACgkQj4D7WH0S /k4zqQgAs6b6PWu99Bh59WbLtqdpo3GfBrxXEGajYfG/rl/WCqTaaR0drQGE+Mlz oqJrJ9klO02JcnPh7tyUi8oIDGm+zJ5Y6au60Ry5aDvZCh370RlXWrqaVJO9dK1k rWfko7rI2/7LFmrpn9Ass/RNjWcL2c/7C9b+NiXfrHlcgdSq49tjBziN6adCOnrF NtOjnAD9jalVxHEaS9z3rhdE714XLvR/NtevzQX5fp9rZylENKrVta0FZnJMX7uD OE6OhsxSyo4nuVpHgL9YLg45JTgzHzIyCJ+GTO0Cjk9oD1UHBKxiv2zOw5j4tBt4 PAQ/yZ10kwJ9IF4j8bxTFYg3PLItLQ== =EWDl -----END PGP SIGNATURE----- Merge tag 'pwm/for-6.14-rc1-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/ukleinek/linux Pull pwm fixes from Uwe Kleine-König: "Two fixes.

power supply and reset changes for the 6.14 series
* power-supply core
- introduce power supply extensions, which allows adding properties to
a power supply device from a separate driver. This will be used
initially to extend the generic ACPI charger/battery driver with
vendor extensions for charge thresholds.
- convert all drivers from power_supply_for_each_device to new
power_supply_for_each_psy(), which avoids lots of casting being
done in the drivers.
- avoid LED trigger like values in uevent for POWER_SUPPLY_PROP_CHARGE_BEHAVIOUR
- introduce POWER_SUPPLY_PROP_CHARGE_TYPES, which is similar to the
POWER_SUPPLY_PROP_CHARGE_TYPE property, but also lists the available
options on the specific platform
* power-supply drivers
- dell-laptop: use new power_supply_charge_types_show/_parse helpers
- stc3117: new driver for equally named fuel gauge chip
- bq24190: add support for new POWER_SUPPLY_PROP_CHARGE_TYPES
- bq24190: add BQ24297 support
- bq27xxx: add voltage min design for bq27000/bq27200
- cros_charge-control: convert to new power supply extension API
- multiple drivers: constify 'struct bin_attribute'
- ds2782: convert to device managed resources
- max1720x: add charge full property
- max1720x: support extra thermistor temperatures
- max17042: add max77705 support
- ip5xxx-power: add support for IP5306
- ltc4162-l-charger: add ltc4162-f/s and ltc4015 support

virtio_blk: Add support for transport error recovery
Add support for proper cleanup and re-initialization of virtio-blk devices during transport reset error recovery flow. This enhancement includes: - Pre-reset handler (reset_prepare) to perform device-specific cleanup - Post-reset handler (reset_done) to re-initialize the device These changes allow the device to recover from various reset scenarios, ensuring proper functionality after a reset event occurs. Without this implementation, the device cannot properly recover from resets, potentially leading to undefined behavior or device malfunction. This feature has been tested using PCI transport with Function Level Reset (FLR) as an example reset mechanism. The reset can be triggered manually via sysfs (echo 1 > /sys/bus/pci/devices/$PCI_ADDR/reset).

fs/proc/vmcore: introduce PROC_VMCORE_DEVICE_RAM to detect device RAM ranges in 2nd kernel
s390 allocates+prepares the elfcore hdr in the dump (2nd) kernel, not in the crashed kernel. RAM provided by memory devices such as virtio-mem can only be detected using the device driver; when vmcore_init() is called, these device drivers are usually not loaded yet, or the devices did not get probed yet. Consequently, on s390 these RAM ranges will not be included in the crash dump, which makes the dump partially corrupt and is unfortunate. Instead of deferring the vmcore_init() call, to an (unclear?) later point, let's reuse the vmcore_cb infrastructure to obtain device RAM ranges as the device drivers probe the device and get access to this information. Then, we'll add these ranges to the vmcore, adding more PT_LOAD entries and updating the offsets+vmcore size. Use a separate Kconfig option to be set by an architecture to include this code only if the arch really needs it. Further, we'll make the config depend on the relevant drivers (i.e., virtio_mem) once they implement support (next). The alternative of having a PROVIDE_PROC_VMCORE_DEVICE_RAM config option was dropped for now for simplicity. The current target use case is s390, which only creates an elf64 elfcore, so focusing on elf64 is sufficient.

fs/proc/vmcore: disallow vmcore modifications while the vmcore is open
The vmcoredd_update_size() call and its effects (size/offset changes) are currently completely unsynchronized, and will cause trouble when performed concurrently, or when done while someone is already reading the vmcore. Let's protect all vmcore modifications by the vmcore_mutex, disallow vmcore modifications while the vmcore is open, and warn on vmcore modifications after the vmcore was already opened once: modifications while the vmcore is open are unsafe, and modifications after the vmcore was opened indicates trouble. Properly synchronize against concurrent opening of the vmcore. No need to grab the mutex during mmap()/read(): after we opened the vmcore, modifications are impossible. It's worth noting that modifications after the vmcore was opened are completely unexpected, so failing if open, and warning if already opened (+closed again) is good enough. This change not only handles concurrent adding of device dumps + concurrent reading of the vmcore properly, it also prepares for other mechanisms that will modify the vmcore.

fs/proc/vmcore: convert vmcore_cb_lock into vmcore_mutex
We want to protect vmcore modifications from concurrent opening of
the vmcore, and also serialize vmcore modification.
(a) We can currently modify the vmcore after it was opened. This can happen
if a vmcoredd is added after the vmcore module was initialized and
already opened by user space. We want to fix that and prepare for
new code wanting to serialize against concurrent opening.
(b) To handle it cleanly we need to protect the modifications against
concurrent opening. As the modifications end up allocating memory and
can sleep, we cannot rely on the spinlock.
Let's convert the spinlock into a mutex to prepare for further changes.

The various patchsets are summarized below. Plus of course many
indivudual patches which are described in their changelogs. - "Allocate and free frozen pages" from Matthew Wilcox reorganizes the page allocator so we end up with the ability to allocate and free zero-refcount pages. So that callers (ie, slab) can avoid a refcount inc & dec. - "Support large folios for tmpfs" from Baolin Wang teaches tmpfs to use large folios other than PMD-sized ones. - "Fix mm/rodata_test" from Petr Tesarik performs some maintenance and fixes for this small built-in kernel selftest. - "mas_anode_descend() related cleanup" from Wei Yang tidies up part of the mapletree code. - "mm: fix format issues and param types" from Keren Sun implements a few minor code cleanups. - "simplify split calculation" from Wei Yang provides a few fixes and a test for the mapletree code. - "mm/vma: make more mmap logic userland testable" from Lorenzo Stoakes continues the work of moving vma-related code into the (relatively) new mm/vma.c. - "mm/page_alloc: gfp flags cleanups for alloc_contig_*()" from David Hildenbrand cleans up and rationalizes handling of gfp flags in the page allocator. - "readahead: Reintroduce fix for improper RA window sizing" from Jan Kara is a second attempt at fixing a readahead window sizing issue. It should reduce the amount of unnecessary reading. - "synchronously scan and reclaim empty user PTE pages" from Qi Zheng addresses an issue where "huge" amounts of pte pagetables are accumulated (https://lore.kernel.org/lkml/cover.1718267194.git.zhengqi.arch@bytedance.com/). Qi's series addresses this windup by synchronously freeing PTE memory within the context of madvise(MADV_DONTNEED). - "selftest/mm: Remove warnings found by adding compiler flags" from Muhammad Usama Anjum fixes some build warnings in the selftests code when optional compiler warnings are enabled. - "mm: don't use __GFP_HARDWALL when migrating remote pages" from David Hildenbrand tightens the allocator's observance of __GFP_HARDWALL. - "pkeys kselftests improvements" from Kevin Brodsky implements various fixes and cleanups in the MM selftests code, mainly pertaining to the pkeys tests. - "mm/damon: add sample modules" from SeongJae Park enhances DAMON to estimate application working set size. - "memcg/hugetlb: Rework memcg hugetlb charging" from Joshua Hahn provides some cleanups to memcg's hugetlb charging logic. - "mm/swap_cgroup: remove global swap cgroup lock" from Kairui Song removes the global swap cgroup lock. A speedup of 10% for a tmpfs-based kernel build was demonstrated. - "zram: split page type read/write handling" from Sergey Senozhatsky has several fixes and cleaups for zram in the area of zram_write_page(). A watchdog softlockup warning was eliminated. - "move pagetable_*_dtor() to __tlb_remove_table()" from Kevin Brodsky cleans up the pagetable destructor implementations. A rare use-after-free race is fixed. - "mm/debug: introduce and use VM_WARN_ON_VMG()" from Lorenzo Stoakes simplifies and cleans up the debugging code in the VMA merging logic. - "Account page tables at all levels" from Kevin Brodsky cleans up and regularizes the pagetable ctor/dtor handling. This results in improvements in accounting accuracy. - "mm/damon: replace most damon_callback usages in sysfs with new core functions" from SeongJae Park cleans up and generalizes DAMON's sysfs file interface logic. - "mm/damon: enable page level properties based monitoring" from SeongJae Park increases the amount of information which is presented in response to DAMOS actions. - "mm/damon: remove DAMON debugfs interface" from SeongJae Park removes DAMON's long-deprecated debugfs interfaces. Thus the migration to sysfs is completed. - "mm/hugetlb: Refactor hugetlb allocation resv accounting" from Peter Xu cleans up and generalizes the hugetlb reservation accounting. - "mm: alloc_pages_bulk: small API refactor" from Luiz Capitulino removes a never-used feature of the alloc_pages_bulk() interface. - "mm/damon: extend DAMOS filters for inclusion" from SeongJae Park extends DAMOS filters to support not only exclusion (rejecting), but also inclusion (allowing) behavior. - "Add zpdesc memory descriptor for zswap.zpool" from Alex Shi "introduces a new memory descriptor for zswap.zpool that currently overlaps with struct page for now. This is part of the effort to reduce the size of struct page and to enable dynamic allocation of memory descriptors." - "mm, swap: rework of swap allocator locks" from Kairui Song redoes and simplifies the swap allocator locking. A speedup of 400% was demonstrated for one workload. As was a 35% reduction for kernel build time with swap-on-zram. - "mm: update mips to use do_mmap(), make mmap_region() internal" from Lorenzo Stoakes reworks MIPS's use of mmap_region() so that mmap_region() can be made MM-internal. - "mm/mglru: performance optimizations" from Yu Zhao fixes a few MGLRU regressions and otherwise improves MGLRU performance. - "Docs/mm/damon: add tuning guide and misc updates" from SeongJae Park updates DAMON documentation. - "Cleanup for memfd_create()" from Isaac Manjarres does that thing. - "mm: hugetlb+THP folio and migration cleanups" from David Hildenbrand provides various cleanups in the areas of hugetlb folios, THP folios and migration. - "Uncached buffered IO" from Jens Axboe implements the new RWF_DONTCACHE flag which provides synchronous dropbehind for pagecache reading and writing. To permite userspace to address issues with massive buildup of useless pagecache when reading/writing fast devices. - "selftests/mm: virtual_address_range: Reduce memory" from Thomas Weißschuh fixes and optimizes some of the MM selftests. -----BEGIN PGP SIGNATURE----- iHUEABYKAB0WIQTTMBEPP41GrTpTJgfdBJ7gKXxAjgUCZ5a+cwAKCRDdBJ7gKXxA jtoyAP9R58oaOKPJuTizEKKXvh/RpMyD6sYcz/uPpnf+cKTZxQEAqfVznfWlw/Lz uC3KRZYhmd5YrxU4o+qjbzp9XWX/xAE= =Ib2s -----END PGP SIGNATURE----- Merge tag 'mm-stable-2025-01-26-14-59' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm Pull MM updates from Andrew Morton: "The various patchsets are summarized below.

firewire updates for v6.14
Two changes for the 6.14 kernel. The first change concerns the PCI driver for 1394 OHCI hardware. Previously, it used legacy PCI suspend/resume callbacks, which have now been replaced with callbacks defined in the Linux generic power management framework. This original patch was posted in 2020 and has been adapted with some modifications for the latest kernel. Note that the driver still includes platform-specific operations for PowerPC, and these operations have not been tested in the new implementation yet. It would be helpful to share the results of suspending/resuming on the platform. The rest is a minor fix for the memory allocation in some KUnit tests. -----BEGIN PGP SIGNATURE----- iHUEABYKAB0WIQQE66IEYNDXNBPeGKSsLtaWM8LwEwUCZ5X2iwAKCRCsLtaWM8Lw E9NHAP40sG56/XbmXvU9AFwIHp9GdmflFc7fpWU7IYLFXiy3PgEAyFvO70axmsbS rbFAt7kzfIW/ylcM7GrCn/c/RcQEvQA= =BZbp -----END PGP SIGNATURE----- Merge tag 'firewire-updates-6.14' of git://git.kernel.org/pub/scm/linux/kernel/git/ieee1394/linux1394 Pull firewire updates from Takashi Sakamoto: "Two changes for the 6.14 kernel.

Modules changes for 6.14-rc1
Several fixes and small improvements are present: - Sign modules with sha512 instead of sha1 by default - Don't fail module loading when setting ro_after_init section RO failed - Constify 'struct module_attribute' - Cleanups and preparation for const struct bin_attribute - Put known GPL offenders in an array - Extend the preempt disabled section in dereference_symbol_descriptor() This has been all on linux-next for at least 2 weeks with no issues. A small merge conflict between the changes here and a pull from the driver-core tree might appear in kernel/module/sysfs.c, function add_notes_attrs(). The code has been cleaned up here and the driver-core additionally changes nattr->read to nattr->read_new. Related to the modules, an important new tool gendwarfksyms to calculate symbols CRCs from DWARF data and thereby enable the modversion support for Rust should come through the kbuild tree. -----BEGIN PGP SIGNATURE----- iQFIBAABCAAyFiEEIduBR9MnFA82q/jtumpXJwqY6poFAmeWOxwUHHBldHIucGF2 bHVAc3VzZS5jb20ACgkQumpXJwqY6ppY0gf/aPhM6fLVArOIcyW1BvO8P4rl/nNp cBvN/WnNB3M1hCASAyCT56u8dDN8pxZYdMvaMKd2rCDGVIdcnXdhBEXmYLbZ4ih2 w56nEJHbtqH2MZcBtrfZgJ4V70poNuKNl0JpTUzya+uGtl4noTfxybjcJXDvlNoO 2Qj6SgblZ35GbEWBW0TrfjwiiHVTADaj2s0V9Pnsmpk472qc4fEMc96U3AGvsGsp b3KJZND2SW1bdTnTyO1SOJBcMeYCKlXb7f3/X7tGqqn7jhjfx1nrfeVG+NLYXaZo XxNi4vzmJCpu3wkOryvxj8WQkkHIqVkldtpM/fmu+GYVRr282LRdOdrY5Q== =GgGQ -----END PGP SIGNATURE----- Merge tag 'modules-6.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/modules/linux Pull modules updates from Petr Pavlu: - Sign modules with sha512 instead of sha1 by default - Don't fail module loading when failing to set the ro_after_init section read-only - Constify 'struct module_attribute' - Cleanups and preparation for const struct bin_attribute - Put known GPL offenders in an array - Extend the preempt disabled section in dereference_symbol_descriptor() * tag 'modules-6.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/modules/linux: module: sign with sha512 instead of sha1 by default module: Don't fail module loading when setting ro_after_init section RO failed module: Split module_enable_rodata_ro() module: sysfs: Use const 'struct bin_attribute' module: sysfs: Add notes attributes through attribute_group module: sysfs: Simplify section attribute allocation module: sysfs: Drop 'struct module_sect_attr' module: sysfs: Drop member 'module_sect_attr::address' module: sysfs: Drop member 'module_sect_attrs::nsections' module: Constify 'struct module_attribute' module: Handle 'struct module_version_attribute' as const params: Prepare for 'const struct module_attribute *' module: Put known GPL offenders in an array module: Extend the preempt disabled section in dereference_symbol_descriptor(). |

rv: tools/rtla: Updates for 6.14
- Add a test suite to test the tool
Add a small test suite that can be used to test rtla's basic features to
at least have something to test when applying changes.
- Automate manual steps in monitor creation
While creating a new monitor in RV, besides generating code from dot2k,
there are a few manual steps which can be tedious and error prone, like
adding the tracepoints, makefile lines and kconfig, or selecting events
that start the monitor in the initial state.
Updates were made to try and automate as much as possible among those steps to
make creating a new RV monitor much quicker. It is still requires to
select proper tracepoints, this step is harder to automate in a general
way and, in several cases, would still need user intervention.
- Have rtla timerlat hist and top set OSNOISE_WORKLOAD flag
Have both rtla-timerlat-hist and rtla-timerlat-top set OSNOISE_WORKLOAD to
the proper value ("on" when running with -k, "off" when running with -u)
every time the option is available instead of setting it only when running
with -u.
This prevents rtla timerlat -k from giving no results when
NO_OSNOISE_WORKLOAD is set, either manually or by an abnormally exited earlier
run of rtla timerlat -u.
- Stop rtla timerlat on signal properly when overloaded
There is an issue where if rtla is run on machines with a high number of
CPUs (100+), timerlat can generate more samples than rtla is able to process
via tracefs_iterate_raw_events. This is especially common when the interval
is set to 100us (rteval and cyclictest default) as opposed to the rtla
default of 1000us, but also happens with the rtla default.
Currently, this leads to rtla hanging and having to be terminated with
SIGTERM. SIGINT setting stop_tracing is not enough, since more and more
events are coming and tracefs_iterate_raw_events never exits.
To fix this: Stop the timerlat tracer on SIGINT/SIGALRM to ensure no more
events are generated when rtla is supposed to exit.
Also on receiving SIGINT/SIGALRM twice, abort iteration immediately with
tracefs_iterate_stop, making rtla exit right away instead of waiting for all
events to be processed.
- Account for missed events
Due to tracefs buffer overflow, it can happen that rtla misses events,
making the tracing results inaccurate.
Count both the number of missed events and the total number of processed
events, and display missed events as well as their percentage. The numbers
are displayed for both osnoise and timerlat, even though for the earlier,
missed events are generally not expected.
For hist, the number is displayed at the end of the run; for top, it is
displayed on each printing of the top table.
- Changes to make osnoise more robust
There was a dependency in the code that the first field of the
osnoise_tool structure was the trace field. If that that ever changed,
then the code work break. Change the code to encapsulate this dependency
where the code that uses the structure does not have this dependency.

Runtime verifier and osnoise fixes for 6.14:
- Reset idle tasks on reset for runtime verifier When the runtime verifier is reset, it resets the task's data that is being monitored. But it only iterates for_each_process() which does not include the idle tasks. As the idle tasks can be monitored, they need to be reset as well. - Fix the enabling and disabling of tracepoints in osnoise If timerlat is enabled and the WORKLOAD flag is not set, then the osnoise tracer will enable the migrate task tracepoint to monitor it for its own workload. The test to enable the tracepoint is done against user space modifiable parameters. On disabling of the tracer, those same parameters are used to determine if the tracepoint should be disabled. The problem is if user space were to modify the parameters after it enables the tracer then it may not disable the tracepoint. Instead, a static variable is used to keep track if the tracepoint was enabled or not. Then when the tracer shuts down, it will use this variable to decide to disable the tracepoint or not, instead of looking at the user space parameters. -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCZ5UJ1BQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qo46AQDjr1yVTyUmzvxe1bMLDoDOq1xeRMRe 4f8CdpOJRxbi0QEAwnl5Ey9Rvcuy8GFpt/USESr4VYWAN10fvsPx7pkphAs= =RYyn -----END PGP SIGNATURE----- Merge tag 'trace-rv-v6.14' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull runtime verifier and osnoise fixes from Steven Rostedt: - Reset idle tasks on reset for runtime verifier When the runtime verifier is reset, it resets the task's data that is being monitored.

LoongArch: Extend the maximum number of watchpoints
The maximum number of load/store watchpoints and fetch instruction
watchpoints is 14 each according to LoongArch Reference Manual, so
extend the maximum number of watchpoints from 8 to 14 for ptrace.
By the way, just simply change 8 to 14 for the definition in struct
user_watch_state at the beginning, but it may corrupt uapi, then add
a new struct user_watch_state_v2 directly.
As far as I can tell, the only users for this struct in the userspace
are GDB and LLDB, there are no any problems of software compatibility
between the application and kernel according to the analysis.
The compatibility problem has been considered while developing and
testing. When the applications in the userspace get watchpoint state,
the length will be specified which is no bigger than the sizeof struct
user_watch_state or user_watch_state_v2, the actual length is assigned
as the minimal value of the application and kernel in the generic code
of ptrace:
kernel/ptrace.c: ptrace_regset():
kiov->iov_len = min(kiov->iov_len,
(__kernel_size_t) (regset->n * regset->size));
if (req == PTRACE_GETREGSET)
return copy_regset_to_user(task, view, regset_no, 0,
kiov->iov_len, kiov->iov_base);
else
return copy_regset_from_user(task, view, regset_no, 0,
kiov->iov_len, kiov->iov_base);
For example, there are four kind of combinations, all of them work well.
(1) "older kernel + older gdb", the actual length is 8+(8+8+4+4)*8=200;
(2) "newer kernel + newer gdb", the actual length is 8+(8+8+4+4)*14=344;
(3) "older kernel + newer gdb", the actual length is 8+(8+8+4+4)*8=200;
(4) "newer kernel + older gdb", the actual length is 8+(8+8+4+4)*8=200.
