sound fixes for 6.5-rc3
A pile of fixes that have been gathered since the previous PR.
Most of changes are device-specific, and nothing looks too scary.
- A memory leak fix in ALSA sequencer code in 6.5-rc
- Many fixes for ASoC Qualcomm CODEC drivers, covering SoundWire probe
problems
- A series of ASoC AMD fixes
- A few fixes and cleanups of selftest stuff
- HD-audio codec fixes and quirks for Clevo, HP, Lenovo, Dell

selftests: tc: add ConnTrack procfs kconfig
When looking at the TC selftest reports, I noticed one test was failing
because /proc/net/nf_conntrack was not available.
not ok 373 3992 - Add ct action triggering DNAT tuple conflict
Could not match regex pattern. Verify command output:
cat: /proc/net/nf_conntrack: No such file or directory
It is only available if NF_CONNTRACK_PROCFS kconfig is set. So the issue
can be fixed simply by adding it to the list of required kconfig.

selftests: tc: add 'ct' action kconfig dep
When looking for something else in LKFT reports [1], I noticed most of
the tests were skipped because the "teardown stage" did not complete
successfully.
Pedro found out this is due to the fact CONFIG_NF_FLOW_TABLE is required
but not listed in the 'config' file. Adding it to the list fixes the
issues on LKFT side. CONFIG_NET_ACT_CT is now set to 'm' in the final
kconfig.

selftests: tc: set timeout to 15 minutes
When looking for something else in LKFT reports [1], I noticed that the
TC selftest ended with a timeout error:
not ok 1 selftests: tc-testing: tdc.sh # TIMEOUT 45 seconds
The timeout had been introduced 3 years ago, see the Fixes commit below.
This timeout is only in place when executing the selftests via the
kselftests runner scripts. I guess this is not what most TC devs are
using and nobody noticed the issue before.
The new timeout is set to 15 minutes as suggested by Pedro [2]. It looks
like it is plenty more time than what it takes in "normal" conditions.

This makes this perf test to stop sometimes failing on some systems due to a full ring buffer. - Avoid SEGV if PMU lookup fails for legacy cache terms. - Fix libsubcmd SEGV/use-after-free when commands aren't excluded. - Fix OpenCSD (ARM64's CoreSight hardware tracing) library path resolution when specifying CSLIBS= in the make command line. - Fix broken feature check for libtracefs due to external lib changes, use the provided pkgconfig file instead future proof it. - Sync drm, fcntl, kvm, mount, prctl, socket, vhost, asound, arm64's cputype headers with the kernel sources, in some cases this made the tools become aware of new kernel APIs such as ioctls and the cachestat sysctl.

perf test task_exit: No need for a cycles event to check if we get an PERF_RECORD_EXIT
The intent of this test is to check we get a PERF_RECORD_EXIT as asked for by setting perf_event_attr.task=1. When the test was written we didn't had the "dummy" event so we went with the default event, "cycles". There were reports of this test failing sometimes, one of these reports was with a PREEMPT_RT_FULL, but I noticed it failing sometimes with an aarch64 Firefly board. In the kernel the call to perf_event_task_output(), that generates the PERF_RECORD_EXIT may fail when there is not enough memory in the ring buffer, if the ring buffer is paused, etc. So switch to using the "dummy" event to use the ring buffer just for what the test was designed for, avoiding uneeded PERF_RECORD_SAMPLEs.

selftests/arm64: fix build failure during the "emit_tests" step
The build failure reported in [1] occurred because commit <9fc96c7c19df>
("selftests: error out if kernel header files are not yet built") added
a new "kernel_header_files" dependency to "all", and that triggered
another, pre-existing problem. Specifically, the arm64 selftests
override the emit_tests target, and that override improperly declares
itself to depend upon the "all" target.
This is a problem because the "emit_tests" target in lib.mk was not
intended to be overridden. emit_tests is a very simple, sequential build
target that was originally invoked from the "install" target, which in
turn, depends upon "all".
That approach worked for years. But with

When run under run_vmtests.sh, test scripts were failing to run with "permission denied" due to the scripts not being executable. It is also annoying not to be able to directly invoke run_vmtests.sh, which is solved by giving also it the execute permission.

Tracing fixes and clean ups:
- Fix some missing-prototype warnings - Fix user events struct args (did not include size of struct) When creating a user event, the "struct" keyword is to denote that the size of the field will be passed in. But the parsing failed to handle this case. - Add selftest to struct sizes for user events - Fix sample code for direct trampolines. The sample code for direct trampolines attached to handle_mm_fault(). But the prototype changed and the direct trampoline sample code was not updated. Direct trampolines needs to have the arguments correct otherwise it can fail or crash the system. - Remove unused ftrace_regs_caller_ret() prototype. - Quiet false positive of FORTIFY_SOURCE Due to backward compatibility, the structure used to save stack traces in the kernel had a fixed size of 8. This structure is exported to user space via the tracing format file. A change was made to allow more than 8 functions to be recorded, and user space now uses the size field to know how many functions are actually in the stack. But the structure still has size of 8 (even though it points into the ring buffer that has the required amount allocated to hold a full stack. This was fine until the fortifier noticed that the memcpy(&entry->caller, stack, size) was greater than the 8 functions and would complain at runtime about it. Hide this by using a pointer to the stack location on the ring buffer instead of using the address of the entry structure caller field. - Fix a deadloop in reading trace_pipe that was caused by a mismatch between ring_buffer_empty() returning false which then asked to read the data, but the read code uses rb_num_of_entries() that returned zero, and causing a infinite "retry". - Fix a warning caused by not using all pages allocated to store ftrace functions, where this can happen if the linker inserts a bunch of "NULL" entries, causing the accounting of how many pages needed to be off. - Fix histogram synthetic event crashing when the start event is removed and the end event is still using a variable from it. - Fix memory leak in freeing iter->temp in tracing_release_pipe() -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCZLBF6hQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qkswAP4mhdoFFfNosM7+Sh/R4t31IxKZApm9 M2Hf9jgvJ7b65AD/VV1XfO6skw2+5Yn9S4UyNE2MQaYxPwWpONcNFUzZ3Q8= =Nb+7 -----END PGP SIGNATURE----- Merge tag 'trace-v6.5-rc1-3' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing fixes from Steven Rostedt: - Fix some missing-prototype warnings - Fix user events struct args (did not include size of struct) When creating a user event, the "struct" keyword is to denote that the size of the field will be passed in.

perf parse-events: Avoid SEGV if PMU lookup fails for legacy cache terms
libfuzzer found the following command could SEGV:

PERF_TYPE_HW_CACHE which then fails the PMU lookup for the second
legacy cache term.
The new failure is consistent with repeated hardware terms:

perf build: Fix broken feature check for libtracefs due to external lib changes
The perf build process auto-detects features and packages already
installed for its build. This is done in directory tools/build/feature.
This directory contains small sample programs. When they successfully
compile the necessary prereqs in form of libraries and header files are
present.
Such a check is also done for libtracefs. And this check fails:
Output before:
# rm -f test-libtracefs.bin; make test-libtracefs.bin
gcc -MD -Wall -Werror -o test-libtracefs.bin test-libtracefs.c \

event-parse.h: No such file or directory
11 | #include <event-parse.h>
| ^~~~~~~~~~~~~~~
compilation terminated.
#
The root cause of this compile error is commit 880885d9c22e
("libtracefs: Remove "traceevent/" from referencing libtraceevent
headers") in the libtracefs project hosted here:
https://git.kernel.org/pub/scm/libs/libtrace/libtracefs.git/
That mentioned patch removes the traceevent/ directory name from
the include statement, causing the file not to be included even
when the libtraceevent-devel package is installed. This package contains
the file referred to in tracefs/tracefs.h:

perf vendor events amd: Fix large metrics
There are cases where a metric requires more events than the number of available counters. E.g. AMD Zen, Zen 2 and Zen 3 processors have four data fabric counters but the "nps1_die_to_dram" metric has eight events. By default, the constituent events are placed in a group and since the events cannot be scheduled at the same time, the metric is not computed. The "all metrics" test also fails because of this. Use the NO_GROUP_EVENTS constraint for such metrics which anyway expect the user to run perf with "--metric-no-group". E.g. $ sudo perf test -v 101 Before: 101: perf all metrics test : --- start --- test child forked, pid 37131 Testing branch_misprediction_ratio Testing all_remote_links_outbound Testing nps1_die_to_dram Metric 'nps1_die_to_dram' not printed in: Error: Invalid event (dram_channel_data_controller_4) in per-thread mode, enable system wide with '-a'.

perf build: Fix library not found error when using CSLIBS
-L only specifies the search path for libraries directly provided in the link line with -l. Because -lopencsd isn't specified, it's only linked because it's a dependency of -lopencsd_c_api. Dependencies like this are resolved using the default system search paths or -rpath-link=... rather than -L. This means that compilation only works if OpenCSD is installed to the system rather than provided with the CSLIBS (-L) option. This could be fixed by adding -Wl,-rpath-link=$(CSLIBS) but that is less conventional than just adding -lopencsd to the link line so that it uses -L. -lopencsd seems to have been removed in commit |

perf probe: Read DWARF files from the correct CU
After switching from dwarf_decl_file() to die_get_decl_file(), it is not
possible to add probes for certain functions:
$ perf probe -x /usr/lib/systemd/systemd-logind match_unit_removed
A function DIE doesn't have decl_line. Maybe broken DWARF?
A function DIE doesn't have decl_line. Maybe broken DWARF?
Probe point 'match_unit_removed' not found.
Error: Failed to add events.
The problem is that die_get_decl_file() uses the wrong CU to search for
the file. elfutils commit e1db5cdc9f has some good explanation for this:
dwarf_decl_file uses dwarf_attr_integrate to get the DW_AT_decl_file
attribute. This means the attribute might come from a different DIE
in a different CU. If so, we need to use the CU associated with the
attribute, not the original DIE, to resolve the file name.
This patch uses the same source of information as elfutils: use attribute
DW_AT_decl_file and use this CU to search for the file.

objtool: initialize all of struct elf
Function elf_open_read() only zero initializes the initial part of
allocated struct elf; num_relocs member was recently added outside the
zeroed part so that it was left uninitialized, resulting in build failures
on some systems.
The partial initialization is a relic of times when struct elf had large
hash tables embedded. This is no longer the case so remove the trap and
initialize the whole structure instead.

perf tools changes and fixes for v6.5: 2nd batch
Build:
- Allow to generate vmlinux.h from BTF using `make GEN_VMLINUX_H=1`
and skip if the vmlinux has no BTF.
- Replace deprecated clang -target xxx option by --target=xxx.
perf record:
- Print event attributes with well known type and config symbols in the
debug output like below:
# perf record -e cycles,cpu-clock -C0 -vv true
<SNIP>

- Update AMD IBS event error message since it now support per-process
profiling but no priviledge filters.
$ sudo perf record -e ibs_op//k -C 0
Error:
AMD IBS doesn't support privilege filtering. Try again without
the privilege modifiers (like 'k') at the end.
perf lock contention:
- Support CSV style output using -x option
$ sudo perf lock con -ab -x, sleep 1
# output: contended, total wait, max wait, avg wait, type, caller

1, 24619, 24619, 24619, spinlock, rcu_core+0xd4
- Add --output option to save the data to a file not to be interfered
by other debug messages.
Test:
- Fix event parsing test on ARM where there's no raw PMU nor supports
PERF_PMU_CAP_EXTENDED_HW_TYPE.
- Update the lock contention test case for CSV output.
- Fix a segfault in the daemon command test.
Vendor events (JSON):
- Add has_event() to check if the given event is available on system
at runtime. On Intel machines, some transaction events may not be
present when TSC extensions are disabled.
- Update Intel event metrics.
Misc:
- Sort symbols by name using an external array of pointers instead of
a rbtree node in the symbol. This will save 16-bytes or 24-bytes
per symbol whether the sorting is actually requested or not.
- Fix unwinding DWARF callstacks using libdw when --symfs option is
used.
