kernel/trace: extract common part in process_fetch_insn
Each probe has an instance of process_fetch_insn respectively, but they have something in common. This patch aims to extract the common part into process_common_fetch_insn which can be shared by each probe, and they only need to focus on their special cases.

kernel/trace: Provide default impelentations defined in trace_probe_tmpl.h
There are 6 function definitions in trace_probe_tmpl.h, they are: 1, fetch_store_strlen 2, fetch_store_string 3, fetch_store_strlen_user 4, fetch_store_string_user 5, probe_mem_read 6, probe_mem_read_user Every C file which includes trace_probe_tmpl.h has to implement them, otherwise it gets warnings and errors. However, some of them are identical, like kprobe and eprobe, as a result, there is a lot redundant code in those 2 files. This patch would like to provide default behaviors for those functions which kprobe and eprobe can share by just including trace_probe_kernel.h with trace_probe_tmpl.h together. It removes redundant code, increases readability, and more importantly, makes it easier to introduce a new feature based on trace probe (it's possible).

print_probe_args is currently inplemented in trace_probe_tmpl.h and included by *probes, as a result, each probe has an identical copy.

- Performance tweaks for efifb earlycon by Andy
- Preparatory refactoring and cleanup work in the efivar layer by Johan,
which is needed to accommodate the Snapdragon arm64 laptops that
expose their EFI variable store via a TEE secure world API.
- Enhancements to the EFI memory map handling so that Xen dom0 can
safely access EFI configuration tables (Demi Marie)
- Wire up the newly introduced IBT/BTI flag in the EFI memory attributes

modules-6.3-rc1
Nothing exciting at all for modules for v6.3. The biggest change is
just the change of INSTALL_MOD_DIR from "extra" to "updates" which
I found lingered for ages for no good reason while testing the CXL
mock driver [0]. The CXL mock driver has no kconfig integration and requires
building an external module... and re-building the *rest* of the production
drivers. This mock driver when loaded but not the production ones will
crash. All this crap can obviously be fixed by integrating kconfig
semantics into such test module, however that's not desirable by
the maintainer, and so sensible defaults must be used to ensure a
default "make modules_install" will suffice for most distros which
do not have a file like /etc/depmod.d/dist.conf with something like
`search updates extra built-in`. Since most distros rely on kmod and
since its inception the "updates" directory is always in the search
path it makes more sense to use that than the "extra" which only
*some* RH based systems rely on. All this stuff has been on linux-next
for a while.
For v6.4 I already have queued some initial work by Song Liu which gets
us slowly going to a place where we *may* see a generic allocator for
huge pages for module text to avoid direct map fragmentation *and*
reduce iTLB pressure. That work is in its initial stages, no allocator
work is done yet. This is all just prep work. Fortunately Thomas Gleixner
has helped convince Song that modules *need* to be *requirement* if we
are going to see any special allocator touch x86. So who knows... maybe
around v6.5 we'll start seeing some *real* performance numbers of the
effect of using huge pages for something other than eBPF toys.
For v6.4 also, you may start seeing patches from Nick Alcock on different
trees and modules-next which aims at extending kallsyms *eventually* to provide
clearer address to symbol lookups. The claim is that this is a *great* *feature*
tracing tools are dying to have so they can for instance disambiguate symbols as
coming from modules or from other parts of the kernel. I'm still waiting to see
proper too usage of such stuff, but *how* we lay this out is still being ironed
out. Part of the initial work I've been pushing for is to help upkeep our
modules build optimizations, so being mindful about the work by Masahiro Yamada

when freeing one stream's prio in sctp_sched_prio_free_sid(). This
can avoid a nested loop (up to 65535 * 65535), which may cause a
stuck as Ying reported:
watchdog: BUG: soft lockup - CPU#23 stuck for 26s! [ksoftirqd/23:136]
Call Trace:
<TASK>
sctp_sched_prio_free_sid+0xab/0x100 [sctp]
sctp_stream_free_ext+0x64/0xa0 [sctp]
sctp_stream_free+0x31/0x50 [sctp]
sctp_association_free+0xa5/0x200 [sctp]
Note that it doesn't need to use refcount_t type for this counter,
as its accessing is always protected under the sock lock.
v1->v2:
- add a check in sctp_sched_prio_set to avoid the possible prio_head
refcnt overflow.

docs: recommend using Link: whenever using Reported-by:
Encourage developers to place Link: tag pointing to the report when they are using Reported-by: tags. Those links are often extremely useful for any code archaeologist that wants to know more about the backstory of a change than the commit message provides. That includes maintainers higher up in the patch-flow hierarchy, which is why Linus asks developers to add such links [1, 2, 3]. To quote [1]: > Again, the commit has a link to the patch *submission*, which is > almost entirely useless. There's no link to the actual problem the > patch fixes. > > [...] > > Put another way: I can see that > > Reported-by: Zhangfei Gao <zhangfei.gao@foxmail.com> > > in the commit, but I don't have a clue what the actual report was, and > there really isn't enough information in the commit itself, except for > a fairly handwavy "Device drivers might, for instance, still need to > flush operations.." > > I don't want to know what device drivers _might_ do. I would want to > have an actual pointer to what they do and where. Another reason why these links are wanted: the ongoing regression tracking efforts can only scale with them, as they allow the regression tracking bot 'regzbot' to automatically connect tracked reports with patches that are posted or committed to fix tracked regressions.

that are documented in doc-guide/sphinx.rst for document title and

This leaves "Indices and tables" as a chapter entry at the same level

The only visual difference from before to after is that the "Indices

Please note that to have the -b option (BPF) working above one has to build
with BUILD_BPF_SKEL=1.
- Add more 'perf test' entries to test these new features.
- Add Ian Rogers to MAINTAINERS as a perf tools reviewer.
- Add support for retire latency feature (pipeline stall of a instruction
compared to the previous one, in cycles) present on some Intel processors.
- Add 'perf c2c' report option to show false sharing with adjacent cachelines, to
be used in machines with cacheline prefetching, where accesses to a cacheline
brings the next one too.
- Skip 'perf test bpf' when the required kernel-debuginfo package isn't installed.
perf script:
- Add 'cgroup' field for 'perf script' output:
$ perf record --all-cgroups -- true
$ perf script -F comm,pid,cgroup
true 337112 /user.slice/user-657345.slice/user@657345.service/...
true 337112 /user.slice/user-657345.slice/user@657345.service/...

true 337112 /user.slice/user-657345.slice/user@657345.service/...
- Add support for showing branch speculation information in 'perf
script' and in the 'perf report' raw dump (-D).
perf record:
- Fix 'perf record' segfault with --overwrite and --max-size.
Intel PT:
- Add support for synthesizing "cycle" events from Intel PT traces as we
support "instruction" events when Intel PT CYC packets are available. This
enables much more accurate profiles than when using the regular 'perf record -e
cycles' (the default) when the workload lasts for very short periods (<10ms).
- .plt symbol handling improvements, better handling IBT (in the past
MPX) done in the context of decoding Intel PT processor traces, IFUNC
symbols on x86_64, static executables, understanding .plt.got symbols on
x86_64.
- Add a 'perf test' to test symbol resolution, part of the .plt
improvements series, this tests things like symbol size in contexts
where only the symbol start is available (kallsyms), etc.
- Better handle auxtrace/Intel PT data when using pipe mode (perf record sleep 1|perf report).
- Fix symbol lookup with kcore with multiple segments match stext,
getting the symbol resolution to just show DSOs as unknown.
ARM:
- Timestamp improvements for ARM64 systems with ETMv4 (Embedded Trace
Macrocell v4).
- Ensure ARM64 CoreSight timestamps don't go backwards.
- Document that ARM64 SPE (Statistical Profiling Extension) is used with 'perf c2c/mem'.
- Add raw decoding for ARM64 SPEv1.2 previous branch address.
- Update neoverse-n2-v2 ARM vendor events (JSON tables): topdown L1, TLB,
cache, branch, PE utilization and instruction mix metrics.
- Update decoder code for OpenCSD version 1.4, on ARM64 systems.
- Fix command line auto-complete of CPU events on aarch64.
perf test/bench:
- Switch basic BPF filtering test to use syscall tracepoint to avoid the
variable number of probes inserted when using the previous probe point
(do_epoll_wait) that happens on different CPU architectures.
- Fix DWARF unwind test by adding non-inline to expected function in a
backtrace.
- Use 'grep -c' where the longer form 'grep | wc -l' was being used.
- Add getpid and execve benchmarks to 'perf bench syscall'.
Miscellaneous:
- Avoid d3-flame-graph package dependency in 'perf script flamegraph',
making this feature more generally available.
- Add JSON metric events to present CPI stall cycles in Power10.
- Assorted improvements/refactorings on the JSON metrics parsing code.
Build:
- Fix 'perf probe' and 'perf test' when libtraceevent isn't linked, as
several tests use tracepoints, those should be skipped.
- More fallout fixes for the removal of tools/lib/traceevent/.
- Fix build error when linking with libpfm.

- Add support for showing branch speculation information in 'perf
script' and in the 'perf report' raw dump (-D).
perf record:
- Fix 'perf record' segfault with --overwrite and --max-size.
perf test/bench:
- Switch basic BPF filtering test to use syscall tracepoint to avoid
the variable number of probes inserted when using the previous
probe point (do_epoll_wait) that happens on different CPU
architectures.
- Fix DWARF unwind test by adding non-inline to expected function in
a backtrace.
- Use 'grep -c' where the longer form 'grep | wc -l' was being used.
- Add getpid and execve benchmarks to 'perf bench syscall'.
Intel PT:
- Add support for synthesizing "cycle" events from Intel PT traces as
we support "instruction" events when Intel PT CYC packets are
available. This enables much more accurate profiles than when using
the regular 'perf record -e cycles' (the default) when the workload
lasts for very short periods (<10ms).
- .plt symbol handling improvements, better handling IBT (in the past
MPX) done in the context of decoding Intel PT processor traces,
IFUNC symbols on x86_64, static executables, understanding .plt.got
symbols on x86_64.
- Add a 'perf test' to test symbol resolution, part of the .plt
improvements series, this tests things like symbol size in contexts
where only the symbol start is available (kallsyms), etc.
- Better handle auxtrace/Intel PT data when using pipe mode (perf
record sleep 1|perf report).
- Fix symbol lookup with kcore with multiple segments match stext,
getting the symbol resolution to just show DSOs as unknown.
ARM:
- Timestamp improvements for ARM64 systems with ETMv4 (Embedded Trace
Macrocell v4).
- Ensure ARM64 CoreSight timestamps don't go backwards.
- Document that ARM64 SPE (Statistical Profiling Extension) is used
with 'perf c2c/mem'.
- Add raw decoding for ARM64 SPEv1.2 previous branch address.
- Update neoverse-n2-v2 ARM vendor events (JSON tables): topdown L1,
TLB, cache, branch, PE utilization and instruction mix metrics.
- Update decoder code for OpenCSD version 1.4, on ARM64 systems.
- Fix command line auto-complete of CPU events on aarch64.
Build:
- Fix 'perf probe' and 'perf test' when libtraceevent isn't linked,
as several tests use tracepoints, those should be skipped.
- More fallout fixes for the removal of tools/lib/traceevent/.
- Fix build error when linking with libpfm"

tracing: Fix race that causes a warning of corrupt ring buffer
With the change that allows to read the "trace" file without disabling writing to the ring buffer, there was an integrity check of the ring buffer in the iterator read code, that expected the ring buffer to be write disabled. This caused the integrity check to trigger when stress reading the "trace" file while writing was happening. The integrity check is a bit aggressive (and has never triggered in practice). Change it so that it checks just the integrity of the linked pages without clearing the flags inside the pointers. This removes the warning that was being triggered. -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCY+05KBQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qm2uAQDpygn75IrW1aApx5wySl2GKo0dSjg9 PaQVTYFYLMxIqgEA7oZQFQwokmZrIThqcQ+JA710+C1xecKYUl+apGza9Qk= =aTTM -----END PGP SIGNATURE----- Merge tag 'trace-v6.2-rc7-3' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing fix from Steven Rostedt: "Fix race that causes a warning of corrupt ring buffer With the change that allows to read the "trace" file without disabling writing to the ring buffer, there was an integrity check of the ring buffer in the iterator read code, that expected the ring buffer to be write disabled.
