Merge tag 'trace-tools-v6.15' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
Pull tracing tooling updates from Steven Rostedt: - Allow RTLA to collect data via BPF The current implementation of rtla uses libtracefs and libtraceevent to pull sample events generated by the timerlat tracer from the trace buffer. rtla then processes the sample by updating the histogram and summary (current, maximum, minimum, and sum values) as well as checks if tracing has been stopped due to threshold overflow. In use cases where a large number of samples is being generated, that is, with measurements running on many CPUs and with a low interval, this sample processing design causes a significant CPU load on the rtla side. Furthermore, with >100 CPUs and 100us interval, rtla was reported as not being able to keep up with the samples and dropping most of them, leading to it being unusable. Change the way the timerlat trace processes samples by attaching a BPF program to the trace event using the BPF skeleton feature of bpftool. Unlike the current implementation, the BPF implementation does not check whether tracing is stopped (in BPF mode, tracing is always off to improve performance), but waits for a write to a BPF ringbuffer instead. This allows rtla to exit immediately when a threshold is violated, without waiting for the next iteration of the while loop. If the requirements for the BPF implementation are not met, either at build time or at run time, the current implementation is used as fallback. Which implementation is being used can be seen when running rtla timerlat with "-D" option. rtla can be forced to run in non-BPF mode by setting the RTLA_NO_BPF option to 1, for debugging purposes. - Fix LD_FLAGS from being dropped in build - Refactor code to remove duplication of save_trace_to_file - Always set options and do not rely on default settings Do not rely on the default kernel settings of the tracers when starting. They could have been changed by the user which gives inconsistent results. Always set the options that rtla expects. - Add creation of ctags and TAGS for traversing code * tag 'trace-tools-v6.15' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: rtla: Add the ability to create ctags and etags rtla/tests: Test setting default options rtla/tests: Reset osnoise options before check rtla: Always set all tracer options rtla/osnoise: Set OSNOISE_WORKLOAD to true rtla: Unify apply_config between top and hist rtla/osnoise: Unify params struct rtla: Fix segfault in save_trace_to_file call tools/build: Use SYSTEM_BPFTOOL for system bpftool rtla: Refactor save_trace_to_file tools/rv: Keep user LDFLAGS in build rtla/timerlat: Test BPF mode rtla/timerlat_top: Use BPF to collect samples rtla/timerlat_top: Move divisor to update rtla/timerlat_hist: Use BPF to collect samples rtla/timerlat: Add BPF skeleton to collect samples rtla: Add optional dependency on BPF tooling tools/build: Add bpftool-skeletons feature test rtla/timerlat: Unify params struct |

Pull tracing updates from Steven Rostedt: - Add option traceoff_after_boot In order to debug kernel boot, it sometimes is helpful to enable tracing via the kernel command line. Unfortunately, by the time the login prompt appears, the trace is overwritten by the init process and other user space start up applications. Adding a "traceoff_after_boot" will disable tracing when the kernel passes control to init which will allow developers to be able to see the traces that occurred during boot. - Clean up the mmflags macros that display the GFP flags in trace events The macros to print the GFP flags for trace events had a bit of duplication. The code was restructured to remove duplication and in the process it also adds some flags that were missed before. - Removed some dead code and scripts/draw_functrace.py draw_functrace.py hasn't worked in years and as nobody complained about it, remove it. - Constify struct event_trigger_ops The event_trigger_ops is just a structure that has function pointers that are assigned when the variables are created.

Merge tag 'trace-latency-v6.15' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
Pull latency tracing updates from Steven Rostedt:
- Add some trace events to osnoise and timerlat sample generation
This adds more information to the osnoise and timerlat tracers as
well as allows BPF programs to be attached to these locations to
extract even more data.
- Fix to DECLARE_TRACE_CONDITION() macro
It wasn't used but now will be and it happened to be broken causing
the build to fail.
- Add scheduler specification monitors to runtime verifier (RV)
This is a continuation of Daniel Bristot's work.
RV allows monitors to run and react concurrently. Running the
cumulative model is equivalent to running single components using the
same reactors, with the advantage that it's easier to point out which
specification failed in case of error.
This update introduces nested monitors to RV, in short, the sysfs
monitor folder will contain a monitor named sched, which is nothing
but an empty container for other monitors. Controlling the sched
monitor (enable, disable, set reactors) controls all nested monitors.
The following scheduling monitors are added:
- sco: scheduling context operations
Monitor to ensure sched_set_state happens only in thread context
- tss: task switch while scheduling
Monitor to ensure sched_switch happens only in scheduling context
- snroc: set non runnable on its own context
Monitor to ensure set_state happens only in the respective task's context
- scpd: schedule called with preemption disabled
Monitor to ensure schedule is called with preemption disabled
- snep: schedule does not enable preempt

Merge tag 'ftrace-v6.15' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
Pull ftrace updates from Steven Rostedt:
- Record function parameters for function and function graph tracers
An option has been added to function tracer (func-args) and the
function graph tracer (funcgraph-args) that when set, the tracers
will record the registers that hold the arguments into each function
event. On reading of the trace, it will use BTF to print those
arguments. Most archs support up to 6 arguments (depending on the
complexity of the arguments) and those are printed.
If a function has more arguments then what was recorded, the output
will end with " ... )".
Example of function graph tracer:
6) | dummy_xmit [dummy](skb = 0x8887c100, dev = 0x872ca000) {
6) | consume_skb(skb = 0x8887c100) {

6) 0.178 us | sock_wfree(skb = 0x8887c100)

Pull tracing / sorttable updates from Steven Rostedt: - Implement arm64 build time sorting of the mcount location table When gcc is used to build arm64, the mcount_loc section is all zeros in the vmlinux elf file. The addresses are stored in the Elf_Rela location. To sort at build time, an array is allocated and the addresses are added to it via the content of the mcount_loc section as well as he Elf_Rela data. After sorting, the information is put back into the Elf_Rela which now has the section sorted. - Make sorting of mcount location table for arm64 work with clang as well When clang is used, the mcount_loc section contains the addresses, unlike the gcc build. An array is still created and the sorting works for both methods. - Remove weak functions from the mcount_loc section Have the sorttable code pass in the data of functions defined via 'nm -S' which shows the functions as well as their sizes. Using this information the sorttable code can determine if a function in the mcount_loc section was weak and overridden. If the function is not found, it is set to be zero. On boot, when the mcount_loc section is read and the ftrace table is created, if the address in the mcount_loc is not in the kernel core text then it is removed and not added to the ftrace_filter_functions (the functions that can be attached by ftrace callbacks). - Update and fix the reporting of how much data is used for ftrace functions On boot, a report of how many pages were used by the ftrace table as well as how they were grouped (the table holds a list of sections that are groups of pages that were able to be allocated). The removing of the weak functions required the accounting to be updated. * tag 'trace-sorttable-v6.15' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: scripts/sorttable: Allow matches to functions before function entry scripts/sorttable: Use normal sort if theres no relocs in the mcount section ftrace: Check against is_kernel_text() instead of kaslr_offset() ftrace: Test mcount_loc addr before calling ftrace_call_addr() ftrace: Have ftrace pages output reflect freed pages ftrace: Update the mcount_loc check of skipped entries scripts/sorttable: Zero out weak functions in mcount_loc table scripts/sorttable: Always use an array for the mcount_loc sorting scripts/sorttable: Have mcount rela sort use direct values arm64: scripts/sorttable: Implement sorting mcount_loc at boot for arm64 |

Merge tag 'bcachefs-2025-03-24' of git://evilpiepirate.org/bcachefs
Pull bcachefs updates from Kent Overstreet:
"On disk format is now soft frozen: no more required/automatic are
anticipated before taking off the experimental label.
Major changes/features since 6.14:
- Scrub
- Blocksize greater than page size support
- A number of "rebalance spinning and doing no work" issues have been
fixed; we now check if the write allocation will succeed in
bch2_data_update_init(), before kicking off the read.
There's still more work to do in this area. Later we may want to
add another bitset btree, like rebalance_work, to track "extents
that rebalance was requested to move but couldn't", e.g. due to
destination target having insufficient online devices.
- We can now support scaling well into the petabyte range: latest
bcachefs-tools will pick an appropriate bucket size at format time
to ensure fsck can run in available memory (e.g. a server with
256GB of ram and 100PB of storage would want 16MB buckets).
On disk format changes:
- 1.21: cached backpointers (scalability improvement)
Cached replicas now get backpointers, which means we no longer rely
on incrementing bucket generation numbers to invalidate cached
data: this lets us get rid of the bucket generation number garbage
collection, which had to periodically rescan all extents to
recompute bucket oldest_gen.
Bucket generation numbers are now only used as a consistency check,
but they're quite useful for that.
- 1.22: stripe backpointers
Stripes now have backpointers: erasure coded stripes have their own
checksums, separate from the checksums for the extents they contain
(and stripe checksums also cover the parity blocks). This is
required for implementing scrub for stripes.
- 1.23: stripe lru (scalability improvement)
Persistent lru for stripes, ordered by "number of empty blocks".
This is used by the stripe creation path, which depending on free
space may create a new stripe out of a partially empty existing
stripe instead of starting a brand new stripe.
This replaces an in-memory heap, and means we no longer have to
read in the stripes btree at startup.
- 1.24: casefolding
Case insensitive directory support, courtesy of Valve.
This is an incompatible feature, to enable mount with
-o version_upgrade=incompatible
- 1.25: extent_flags
Another incompatible feature requiring explicit opt-in to enable.
This adds a flags entry to extents, and a flag bit that marks
extents as poisoned.
A poisoned extent is an extent that was unreadable due to checksum
errors. We can't move such extents without giving them a new
checksum, and we may have to move them (for e.g. copygc or device
evacuate). We also don't want to delete them: in the future we'll
have an API that lets userspace ignore checksum errors and attempt
to deal with simple bitrot itself. Marking them as poisoned lets us
continue to return the correct error to userspace on normal read
calls.
Other changes/features:
- BCH_IOCTL_QUERY_COUNTERS: this is used by the new 'bcachefs fs top'
command, which shows a live view of all internal filesystem
counters.
- Improved journal pipelining: we can now have 16 journal writes in
flight concurrently, up from 4. We're logging significantly more to
the journal than we used to with all the recent disk accounting
changes and additions, so some users should see a performance
increase on some workloads.
- BCH_MEMBER_STATE_failed: previously, we would do no IO at all to
devices marked as failed. Now we will attempt to read from them,
but only if we have no better options.
- New option, write_error_timeout: devices will be kicked out of the
filesystem if all writes have been failing for x number of seconds.
We now also kick devices out when notified by blk_holder_ops that
they've gone offline.
- Device option handling improvements: the discard option should now
be working as expected (additionally, in -tools, all device options
that can be set at format time can now be set at device add time,
i.e. data_allowed, state).
- We now try harder to read data after a checksum error: we'll do
additional retries if necessary to a device after after it gave us
data with a checksum error.
- More self healing work: the full inode <-> dirent consistency
checks that are currently run by fsck are now also run every time
we do a lookup, meaning we'll be able to correct errors at runtime.
Runtime self healing will be flipped on after the new changes have
seen more testing, currently they're just checking for consistency.
- KMSAN fixes: our KMSAN builds should be nearly clean now, which
will put a massive dent in the syzbot dashboard"

Pull btrfs updates from David Sterba:
"User visible changes:
- fall back to buffered write if direct io is done on a file that
requires checksums
- this avoids a problem with checksum mismatch errors, observed
e.g. on virtual images when writes to pages under writeback
cause the checksum mismatch reports
- this may lead to some performance degradation but currently the
recommended setup for VM images is to use the NOCOW file
attribute that also disables checksums
- fast/realtime zstd levels -15 to -1
- supported by mount options (compress=zstd:-5) and defrag ioctl
- improved speed, reduced compression ratio, check the commit for
sample measurements
- defrag ioctl extended to accept negative compression levels
- subpage mode
- remove warning when subpage mode is used, the feature is now
reasonably complete and tested
- in debug mode allow to create 2K b-tree nodes to allow testing
subpage on x86_64 with 4K pages too
Performance improvements:
- in send, better file path caching improves runtime (on sample load
by -30%)
- on s390x with hardware zlib support prepare the input buffer in a
better way to get the best results from the acceleration
- minor speed improvement in encoded read, avoid memory allocation in
synchronous mode
Core:
- enable stable writes on inodes, replacing manually waiting for
writeback and allowing to skip that on inodes without checksums
- add last checks and warnings for out-of-band dirty writes to pages,
requiring a fixup ("fixup worker"), this should not be necessary
since 5.8 where get_user_page() and pin_user_pages*() prevent this
- long history behind that, we'll be happy to remove the whole
infrastructure in the near future
- more folio API conversions and preparations for large folio support
- subpage cleanups and refactoring, split handling of data and
metadata to allow future support for large folios
- readpage works as block-by-block, no change for normal mode, this
is preparation for future subpage updates
- block group refcount fixes and hardening
- delayed iput fixes
- in zoned mode, fix zone activation on filesystem with missing
devices
Cleanups:
- inode parameter cleanups
- path auto-freeing updates
- code flow simplifications in send
- redundant parameter cleanups"

Amlogic devices.
The Arm Morello reference platform gets a devicetree for booting in
normal aarch64 mode. The hardware supports experimental CHERI support,
which requires a modified kernel.
The AMD (formerly Xilinx) Versal NET SoC gets added, this is a
combined FPGA with Cortex-A78 CPUs in a SoC.
Six new ST STM32MP2 SoC variants are added. Like the earlier
STM32MP25, the MP211, MP213, MP215, MP231, MP233 and MP235 models are
based on one or two Cortex-A35 cores but each feature a different set
of I/O devices.
Mediatek MT8370 is a minor variation of MT8390 with fewer CPU and GPU
cores
Apple T2 is the baseboard management controller on earlier Intel CPU
based Macs, with 16 models now gaining initial support.
All the above come with dts files for the reference boards. In
addition, these boards are added for the SoCs that are already
supported:
- The Milk-V Jupiter board based on SpacemiT K1/M1
- NetCube Systems Kumquat board based on the 32-bit Allwinner V3s SoC
- Three boards based on 32-bit stm32mp1
- 11 distinct board variants from Toradex and one from Variscite, all

"Core & protocols:
- Continue Netlink conversions to per-namespace RTNL lock
(IPv4 routing, routing rules, routing next hops, ARP ioctls)
- Continue extending the use of netdev instance locks. As a driver
opt-in protect queue operations and (in due course) ethtool
operations with the instance lock and not RTNL lock.
- Support collecting TCP timestamps (data submitted, sent, acked) in
BPF, allowing for transparent (to the application) and lower
overhead tracking of TCP RPC performance.
- Tweak existing networking Rx zero-copy infra to support zero-copy
Rx via io_uring.
- Optimize MPTCP performance in single subflow mode by 29%.
- Enable GRO on packets which went thru XDP CPU redirect (were queued
for processing on a different CPU). Improving TCP stream
performance up to 2x.
- Improve performance of contended connect() by 200% by searching for
an available 4-tuple under RCU rather than a spin lock. Bring an
additional 229% improvement by tweaking hash distribution.
- Avoid unconditionally touching sk_tsflags on RX, improving
performance under UDP flood by as much as 10%.
- Avoid skb_clone() dance in ping_rcv() to improve performance under
ping flood.
- Avoid FIB lookup in netfilter if socket is available, 20% perf win.
- Rework network device creation (in-kernel) API to more clearly
identify network namespaces and their roles. There are up to 4
namespace roles but we used to have just 2 netns pointer arguments,
interpreted differently based on context.
- Use sysfs_break_active_protection() instead of trylock to avoid
deadlocks between unregistering objects and sysfs access.

Merge tag 'sysctl-6.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/sysctl/sysctl
Pull sysctl updates from Joel Granados:
- Move vm_table members out of kernel/sysctl.c
All vm_table array members have moved to their respective subsystems
leading to the removal of vm_table from kernel/sysctl.c. This
increases modularity by placing the ctl_tables closer to where they
are actually used and at the same time reducing the chances of merge
conflicts in kernel/sysctl.c.
- ctl_table range fixes
Replace the proc_handler function that checks variable ranges in
coredump_sysctls and vdso_table with the one that actually uses the
extra{1,2} pointers as min/max values. This tightens the range of the
values that users can pass into the kernel effectively preventing
{under,over}flows.
- Misc fixes
Correct grammar errors and typos in test messages. Update sysctl
files in MAINTAINERS. Constified and removed array size in

"This is the first of the io_uring pull requests for the 6.15 merge
window, there will be others once the net tree has gone in. This
contains:
- Cleanup and unification of cancelation handling across various
request types.
- Improvement for bundles, supporting them both for incrementally
consumed buffers, and for non-multishot requests.
- Enable toggling of using iowait while waiting on io_uring events or
not. Unfortunately this is still tied with CPU frequency boosting
on short waits, as the scheduler side has not been very receptive
to splitting the (useless) iowait stat from the cpufreq implied
boost.
- Add support for kbuf nodes, enabling zero-copy support for the ublk
block driver.
- Various cleanups for resource node handling.
- Series greatly cleaning up the legacy provided (non-ring based)
buffers. For years, we've been pushing the ring provided buffers as
the way to go, and that is what people have been using. Reduce the
complexity and code associated with legacy provided buffers.
- Series cleaning up the compat handling.
- Series improving and cleaning up the recvmsg/sendmsg iovec and msg
handling.
- Series of cleanups for io-wq.
- Start adding a bunch of selftests. The liburing repository
generally carries feature and regression tests for everything, but
at least for ublk initially, we'll try and go the route of having
it in selftests as well. We'll see how this goes, might decide to
migrate more tests this way in the future.

rwonce: fix crash by removing READ_ONCE() for unaligned read
When arm64 is built with LTO, it upgrades READ_ONCE() to ldar / ldapr
(load-acquire) to avoid issues that can be caused by the compiler
optimizing away implicit address dependencies.
Unlike plain loads, these load-acquire instructions actually require an
aligned address.
For now, fix it by removing the READ_ONCE() that the buggy commit
introduced.

Pull MSI irq fix from Thomas Gleixner: "An urgent fix for the XEN related PCI/MSI changes: XEN used a global variable to disable the masking of MSI interrupts as XEN handles that on the hypervisor side. This turned out to be a problem with VMD as the PCI devices behind a VMD bridge are not always handled by the hypervisor and then require masking by guest. To solve this the global variable was replaced by a interrupt domain specific flag, which is set by the generic XEN PCI/MSI domain, but not by VMD or any other domain in the system. So far, so good. But the implementation (and the reviewer) missed the fact, that accessing the domain flag cannot be done directly because there are at least two situations, where this fails. Legacy architectures are not providing interrupt domains at all. The new MSI parent domains do not require to have a domain info pointer. Both cases result in a unconditional NULL pointer derefence. The PCI/MSI code already has a function to query the MSI domain specific flag in a safe way, which handles all possible cases of PCI/MSI backends. So the fix it simply to replace the open coded checks by invoking the safe helper to query the flag" * tag 'irq-urgent-2025-03-26' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: PCI/MSI: Handle the NOMASK flag correctly for all PCI/MSI backends |
