Pull ring-buffer updates from Steven Rostedt
- Do not invalidate entire buffer for invalid sub-buffers
For the persistent ring buffer, if one sub-buffer is found to be
invalid, it invalidates the entire per CPU ring buffer. This can lose
a lot of valuable data if there's some corruption with the writes to
the buffer not syncing properly on a hard crash. Instead, if a
sub-buffer is found to be invalid, simply zero it out and mark it for
"missed events".
When the persistent ring buffer is read and a sub-buffer that was
cleared due to being invalid on boot up is discovered, the output
will show "[LOST EVENTS]" to let the user know that events were
missing at that location. Displaying the events from valid buffers
can still be useful.
- Add a test to be able to test corrupted sub-buffers
If a persistent ring buffer is created as "ptraingtest" and the new
config that adds the test is enabled, when a panic happens, the
kernel will randomly corrupt one of the per CPU ring buffers. On boot
up, the sub-buffers with the corruption should be cleared and
flagged. When reading this buffer, the missed events should should
[LOST EVENTS].
- Add commit number in the sub-buffer meta debug info
The commit is used to know the content of a meta page. Add it to the
buffer_meta file that is shown for each per CPU buffer.
- Clean up the persistent ring buffer validation code
Add some helper functions and make variable names more consistent.

Merge tag 'trace-v7.2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
Pull tracing updates from Steven Rostedt:
- Remove a redundant IS_ERR() check
trace_pipe_open() already checks for IS_ERR() and does it again in
the return path. Remove the return check.
- Export seq_buf_putmem_hex() to allow kunit tests against them
To add Kunit tests on seq_buf_putmem_hex(), it needs to be exported.
- Replace strcat() and strcpy() with seq_buf() logic
The code for synthetic events uses a series of strcat() and strcpy()
which can be error prone. Replace them with seq_buf() logic that does
all the necessary bound checking.
- Add a lockdep rcu_is_watching() to trace_##event##_enabled() call
The trace_##event##_enabled() is a static branch that is true if the
"event" is enabled. But this can hide bugs if this logic is in a
location where RCU is disabled and not "watching". It would only
trigger if lockdep is enabled and the event is enabled.
Add a "rcu_is_watching()" warning if lockdep is enabled in that
helper function to trigger regardless if the event is enabled or not.
- Remove the local variable in the trace_printk() macro
For name space integrity, remove the _______STR variable in the
trace_printk() macro for using the sizeof() macro directly.
- Use guard()s for the trace_recursion_record.c file
- Fix typo in a comment of eventfs_callback() kerneldoc
- Use trace_call__##event() in events within trace_##event##_enabled()
A couple of events are called within an if block guarded by
trace_##event##_enabled(). That is a static key that is only enabled
when the event is enabled. The trace_call_##event() calls the
tracepoint code directly without adding a redundant static key for
that check.
- Allow perf to read synthetic events
Currently, perf does not have the ability to enable a synthetic
event. If it does, it will either cause a kernel warning or error
with "No such device". Synthetic events are not much different than
kprobes and perf can handle fine with a few modifications.
- Replace printk(KERN_WARNING ...) with pr_warn()
- Replace krealloc() on an array with krealloc_array()
- Fix README file path name for synthetic events
- Change tracing_map tracing_map_array to use a flexible array
Instead of allocating a separate pointer to hold the pages field of
tracing_map_array, allocate the pages field as a flexible array when
allocating the structure.
- Fold trace_iterator_increment() into trace_find_next_entry_inc()
The function trace_iterator_increment() was only used by
trace_find_next_entry_inc(). It's not big enough to be a helper
function for one user. Fold it into its caller.
- Make field_var_str field a flexible array of hist_elt_data
Instead of allocating a separate pointer for the field_var_str array
of the hist_elt_data structure, allocate it as a flexible array when
allocating the structure.
- Disable KCOV for trace_irqsoff.c
Like trace_preemptirq.c, trace_irqsoff.c has code that will crash
when KCOV is enabled on ARM. The irqsoff tracing can be called on ARM
because the irqsoff tracing code can be run from early interrupt code
and produce coverage unrelated to syscall inputs.
- Fix warning in __unregister_ftrace_function() called by perf
Perf calls unregister_ftrace_function() without checking if its
ftrace_ops has already been unregistered. There's an error path where
on clean up it will unregister the ftrace_ops even if it wasn't
registered and causes a warning.

Pull nfsd updates from Chuck Lever:
"Jeff Layton wired up netlink upcalls for the auth.unix.ip and
auth.unix.gid caches in SunRPC and the svc_export and nfsd.fh caches
in NFSD. The new kernel-user API is more extensible and lays the
groundwork for retiring the old pipe interface.
The default NFS r/w block size rises to 4MB on hosts with at least
16GB of RAM, reducing per-RPC overhead on fast networks. Smaller
machines keep their previously computed default, and the value remains
tunable through /proc/fs/nfsd/max_block_size.
Chuck Lever converted the server's RPCSEC GSS Kerberos code to the
kernel's shared crypto/krb5 library. The conversion retires and
removes SunRPC's bespoke implementation of Kerberos v5, but keeps
RPCSEC GSS-API.
Continuing the xdrgen migration that converted the NLMv4 server XDR
layer in v7.1, Chuck Lever converted the NLM version 3 server-side XDR
layer from hand-written C to xdrgen-generated code. As with the NLMv4
conversion in v7.1, the goals are improved memory safety, lower
maintenance burden, and groundwork for generation of Rust code for
this layer instead of C.
Chuck Lever fixed an issue where lingering NFSv4 state pins a mounted
file system after it is unexported. A new netlink-based mechanism can
now release NLM locks and NFSv4 state by client address, by
filesystem, and by export. Now an administrator can quiesce an export
cleanly before unmounting it.
The remaining patches are bug fixes, clean-ups, and minor
optimizations, including a batch of memory-leak and use-after-free
fixes in the ACL, lockd, and TLS handshake paths, many of them
reported by Chris Mason. Sincere thanks to all contributors,
reviewers, testers, and bug reporters who participated in the v7.2
NFSD development cycle"

"Most of this continues the in-development sub-scheduler support, which
lets a root BPF scheduler delegate to nested sub-schedulers. The
dispatch-path building blocks landed in 7.1. A follow-up patchset in
development will complete enqueue-path support for hierarchical
scheduling. This cycle adds most of that infrastructure:
- Topological CPU IDs (cids): a dense, topology-ordered CPU numbering
where the CPUs of a core, LLC, or NUMA node form contiguous ranges,
so a topology unit becomes a (start, length) slice. Raw CPU numbers
are sparse and don't track topological closeness, which makes them
clumsy for sharding work across sub-schedulers and awkward in BPF.
- cmask: bitmaps windowed over a slice of cid space, so a
sub-scheduler can track, for example, the idle cids of its shard
without a full NR_CPUS cpumask.
- A struct_ops variant that cid-form sub-schedulers register with,
along with the cid-form kfuncs they call.
- BPF arena integration, which sub-scheduler support is built on. The
bpf-next additions let the kernel read and write the BPF
scheduler's arena directly, turning it into a real kernel/BPF
shared-memory channel. Shared state like the per-CPU cmask now
lives there.
- scx_qmap is reworked to exercise the new arena and cid interfaces.
Additionally:
- Exit-dump improvements: dump the faulting CPU first, expose the
exit CPU to BPF and userspace, and normalize the dump header.
- Misc kfuncs and cleanups: a task-ID lookup kfunc, __printf checking
on the error and dump formatters, header reorganization, and
assorted fixes"
