radix tree test suite: fix incorrect allocation size for pthreads
Currently the pthread allocation for each array item is based on the size
of a pthread_t pointer and should be the size of the pthread_t structure,
so the allocation is under-allocating the correct size. Fix this by using
the size of each element in the pthreads array.
Static analysis cppcheck reported:
tools/testing/radix-tree/regression1.c:180:2: warning: Size of pointer
'threads' used instead of size of its data. [pointerSize]

Second set of Counter fixes for 6.5
The I8254 Kconfig entry is repositioned to resolve a misplacement causing the "Counter support" submenu items to disappear in menuconfig. The tools/counter/Makefile clean recipe is adjusted to replace rmdir with an equivalent set of rm to prevent failure if someone tries to clean the counter directory without building it first. -----BEGIN PGP SIGNATURE----- iHUEABYKAB0WIQSNN83d4NIlKPjon7a1SFbKvhIjKwUCZL6LvQAKCRC1SFbKvhIj KwvCAP9sFxLdOfi6npw1RelvbdQb2wS/c9AMhxJOCxo5G45uWwEAlfnwIl/vo5jN tLbTdUBQTADep4Cokotv5aFW8G+rOwI= =ynvU -----END PGP SIGNATURE----- Merge tag 'counter-fixes-for-6.5b' of git://git.kernel.org/pub/scm/linux/kernel/git/wbg/counter into char-misc-linus William writes: Second set of Counter fixes for 6.5 The I8254 Kconfig entry is repositioned to resolve a misplacement causing the "Counter support" submenu items to disappear in menuconfig.

perf tools fixes for 6.5: 2nd batch
- Fix segfault in the powerpc specific arch_skip_callchain_idx function. The patch doing the reference count init/exit that went into 6.5 missed this function. - Fix regression reading the arm64 PMU cpu slots in sysfs, a patch removing some code duplication ended up duplicating the /sysfs prefix for these files. - Fix grouping of events related to topdown, addressing a regression on the CSV output produced by 'perf stat' noticed on the downstream tool toplev. - Fix the uprobe_from_different_cu 'perf test' entry, it is failing when gcc isn't available, so we need to check that and skip the test if it is not installed.

Including fixes from bpf and wireless.
Nothing scary here. Feels like the first wave of regressions
from v6.5 is addressed - one outstanding fix still to come
in TLS for the sendpage rework.
Current release - regressions:
- udp: fix __ip_append_data()'s handling of MSG_SPLICE_PAGES
- dsa: fix older DSA drivers using phylink
Previous releases - regressions:
- gro: fix misuse of CB in udp socket lookup
- mlx5: unregister devlink params in case interface is down
- Revert "wifi: ath11k: Enable threaded NAPI"
Previous releases - always broken:
- sched: cls_u32: fix match key mis-addressing
- sched: bind logic fixes for cls_fw, cls_u32 and cls_route
- add bound checks to a number of places which hand-parse netlink
- bpf: disable preemption in perf_event_output helpers code
- qed: fix scheduling in a tasklet while getting stats
- avoid using APIs which are not hardirq-safe in couple of drivers,
when we may be in a hard IRQ (netconsole)
- wifi: cfg80211: fix return value in scan logic, avoid page
allocator warning
- wifi: mt76: mt7615: do not advertise 5 GHz on first PHY
of MT7615D (DBDC)
Misc:
- drop handful of inactive maintainers, put some new in place

Dan Carpenter reported an error spotted by Smatch.

error: uninitialized symbol 'ret'.
The returned value of sched_setaffinity() should be checked with
ASSERT_EQ(), but the value was not saved in a proper variable,
resulting in an error above.
Let's save the returned value of with sched_setaffinity().

perf test parse-events: Test complex name has required event format
test__checkevent_complex_name will use an "event" format which if not
present, such as with a placeholder PMU, will cause test failures. Skip
the test in this case to avoid failures in restricted environments.
Add perf_pmu__has_format utility as a general PMU utility.

net/sched: taprio: Limit TCA_TAPRIO_ATTR_SCHED_CYCLE_TIME to INT_MAX.
syzkaller found zero division error [0] in div_s64_rem() called from
get_cycle_time_elapsed(), where sched->cycle_time is the divisor.
We have tests in parse_taprio_schedule() so that cycle_time will never
be 0, and actually cycle_time is not 0 in get_cycle_time_elapsed().
The problem is that the types of divisor are different; cycle_time is
s64, but the argument of div_s64_rem() is s32.
syzkaller fed this input and 0x100000000 is cast to s32 to be 0.
@TCA_TAPRIO_ATTR_SCHED_CYCLE_TIME={0xc, 0x8, 0x100000000}
We use s64 for cycle_time to cast it to ktime_t, so let's keep it and
set max for cycle_time.
While at it, we prevent overflow in setup_txtime() and add another
test in parse_taprio_schedule() to check if cycle_time overflows.
Also, we add a new tdc test case for this issue.

KVM: selftests: Expand x86's sregs test to cover illegal CR0 values
Add coverage to x86's set_sregs_test to verify KVM rejects vendor-agnostic
illegal CR0 values, i.e. CR0 values whose legality doesn't depend on the
current VMX mode. KVM historically has neglected to reject bad CR0s from
userspace, i.e. would happily accept a completely bogus CR0 via
KVM_SET_SREGS{2}.
Punt VMX specific subtests to future work, as they would require quite a
bit more effort, and KVM gets coverage for CR0 checks in general through
other means, e.g. KVM-Unit-Tests.

KVM: selftests: Verify stats fd is usable after VM fd has been closed
Verify that VM and vCPU binary stats files are usable even after userspace has put its last direct reference to the VM.

KVM: selftests: Verify stats fd can be dup()'d and read
Expand the binary stats test to verify that a stats fd can be dup()'d and read, to (very) roughly simulate userspace passing around the file. Adding the dup() test is primarily an intermediate step towards verifying that userspace can read VM/vCPU stats before _and_ after userspace closes its copy of the VM fd; the dup() test itself is only mildly interesting.

selftests/rseq: Play nice with binaries statically linked against glibc 2.35+
To allow running rseq and KVM's rseq selftests as statically linked
binaries, initialize the various "trampoline" pointers to point directly
at the expect glibc symbols, and skip the dlysm() lookups if the rseq
size is non-zero, i.e. the binary is statically linked *and* the libc
registered its own rseq.
Define weak versions of the symbols so as not to break linking against
libc versions that don't support rseq in any capacity.
The KVM selftests in particular are often statically linked so that they
can be run on targets with very limited runtime environments, i.e. test
machines.

perf parse-events: Only move force grouped evsels when sorting
Prior to this change, events without a group would be sorted as if they
were from the location of the first event without a group. For example
instructions and cycles are without a group:
instructions,{imc_free_running/data_read/,imc_free_running/data_write/},cycles
parse events would create an eventual evlist like:
instructions,cycles,{uncore_imc_free_running_0/data_read/,uncore_imc_free_running_1/data_read/,uncore_imc_free_running_0/data_write/,uncore_imc_free_running_1/data_write/}
This is done so that perf metric events, that must always be in a
group, will be adjacent and so can be forced into a group.
This change modifies the sorting so that only force grouped events,
like perf metrics, are sorted and all other events keep their position
with respect to groups in the evlist. The location of the force
grouped event is chosen to match the first force grouped event.
For architectures without force grouped events, ie anything not Intel
Icelake or newer, this should mean sorting and fixing doesn't modify
the event positions except when fixing the grouping for PMUs of things
like uncore events.

perf parse-events: When fixing group leaders always set the leader
The evsel grouping fix iterates over evsels tracking the leader group
and the current position's group, updating the current position's leader
if an evsel is being forced into a group or groups changed. However,
groups changing isn't a sufficient condition as sorting may have
reordered events and the leader may no longer come first. For this
reason update all leaders whenever they disagree.
This change breaks certain Icelake+ metrics due to bugs in the
kernel. For example, tma_l3_bound with threshold enabled tries to
program the events:
{topdown-retiring,slots,CYCLE_ACTIVITY.STALLS_L2_MISS,topdown-fe-bound,EXE_ACTIVITY.BOUND_ON_STORES,EXE_ACTIVITY.1_PORTS_UTIL,topdown-be-bound,cpu/INT_MISC.RECOVERY_CYCLES,cmask=1,edge/,CYCLE_ACTIVITY.STALLS_L3_MISS,CPU_CLK_UNHALTED.THREAD,CYCLE_ACTIVITY.STALLS_MEM_ANY,EXE_ACTIVITY.2_PORTS_UTIL,CYCLE_ACTIVITY.STALLS_TOTAL,topdown-bad-spec}:W
fixing the perf metric event order gives:
{slots,topdown-retiring,topdown-fe-bound,topdown-be-bound,topdown-bad-spec,CYCLE_ACTIVITY.STALLS_L2_MISS,EXE_ACTIVITY.BOUND_ON_STORES,EXE_ACTIVITY.1_PORTS_UTIL,cpu/INT_MISC.RECOVERY_CYCLES,cmask=1,edge/,CYCLE_ACTIVITY.STALLS_L3_MISS,CPU_CLK_UNHALTED.THREAD,CYCLE_ACTIVITY.STALLS_MEM_ANY,EXE_ACTIVITY.2_PORTS_UTIL,CYCLE_ACTIVITY.STALLS_TOTAL}:W
Both of these return "<not counted>" for all events, whilst they work
with the group removed respecting that the perf metric events must still
be grouped. A vendor events update will need to add METRIC_NO_GROUP to
these metrics to workaround the kernel PMU driver issue.

perf parse-events: Extra care around force grouped events
Perf metric (topdown) events on Intel Icelake+ machines require a
group, however, they may be next to events that don't require a group.
Consider:
cycles,slots,topdown-fe-bound
The cycles event needn't be grouped but slots and topdown-fe-bound need
grouping.
Prior to this change, as slots and topdown-fe-bound need a group forcing
and all events share the same PMU, slots and topdown-fe-bound would be
forced into a group with cycles.
This is a bug on two fronts, cycles wasn't supposed to be grouped and
cycles can't be a group leader with a perf metric event.
This change adds recognition that cycles isn't force grouped and so it
shouldn't be force grouped with slots and topdown-fe-bound.

x86/srso: Add a Speculative RAS Overflow mitigation
Add a mitigation for the speculative return address stack overflow vulnerability found on AMD processors. The mitigation works by ensuring all RET instructions speculate to a controlled location, similar to how speculation is controlled in the retpoline sequence. To accomplish this, the __x86_return_thunk forces the CPU to mispredict every function return using a 'safe return' sequence. To ensure the safety of this mitigation, the kernel must ensure that the safe return sequence is itself free from attacker interference. In Zen3 and Zen4, this is accomplished by creating a BTB alias between the untraining function srso_untrain_ret_alias() and the safe return function srso_safe_ret_alias() which results in evicting a potentially poisoned BTB entry and using that safe one for all function returns. In older Zen1 and Zen2, this is accomplished using a reinterpretation technique similar to Retbleed one: srso_untrain_ret() and srso_safe_ret(). Signed-off-by: Borislav Petkov (AMD) <bp@alien8.de> |

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.

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

selftests/mm: give scripts execute permission
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:

This is because the L2 term rewrites the perf_event_attr type to
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:
# rpm -ql libtraceevent-devel

With this patch the compile succeeds.

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.

- 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

- 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.

asm-generic updates for 6.5
These are cleanups for architecture specific header files:
- the comments in include/linux/syscalls.h have gone out of sync
and are really pointless, so these get removed
- The asm/bitsperlong.h header no longer needs to be architecture
specific on modern compilers, so use a generic version for newer
architectures that use new enough userspace compilers
- A cleanup for virt_to_pfn/virt_to_bus to have proper type
checking, forcing the use of pointers

selftests/bpf: Add selftest for check_stack_max_depth bug
Use the bpf_timer_set_callback helper to mark timer_cb as an async callback, and put a direct call to timer_cb in the main subprog. As the check_stack_max_depth happens after the do_check pass, the order does not matter. Without the previous fix, the test passes successfully.

perf test: Fix event parsing test when PERF_PMU_CAP_EXTENDED_HW_TYPE isn't supported.
Arm has multiple PMU types for heterogeneous systems, but doesn't
currently support PERF_PMU_CAP_EXTENDED_HW_TYPE. Make the tests
support both scenarios so that they pass on Arm, and will still pass
once PERF_PMU_CAP_EXTENDED_HW_TYPE support is added.

perf test: Fix event parsing test on Arm
The test looks for a PMU from sysfs with type = PERF_TYPE_RAW when
opening a raw event. Arm doesn't have a real raw PMU, only core PMUs
with unique types other than raw.
Instead of looking for a matching PMU, just test that the event type
was parsed as raw and skip the PMU search on Arm. The raw event type
test should also apply to all platforms so add it outside of the ifdef.

Tracing tooling updates for 6.5:
- Add cgroup support for rtla via the -C option - Add --house-keeping option that tells rtla where to place the housekeeping threads. - Have rtla/timerlat have its own tracing instance instead of using the top level tracing instance that is the default for other tracing users to use. - Add auto analysis to timerlat_hist - Have rtla start the tracers after creating the instances - Reduce rtla hwnoise down to 75% from 100% as it runs with preemption disabled and can cause system instability at 100%. - Add support to run timerlat_top and timerlat_hist threads in user-space instead of just using the kernel tasks. - Some minor clean ups and documentation changes. -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCZKQazxQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qn+kAP4uksUlaic1j4eB44pJCdVuia7+WT5N LNwAyOqcupKlRwD9GDjLZf4JgnHkHHFgFmVts3UTQmKmL71YkTTc3aXdVw8= =CC6L -----END PGP SIGNATURE----- Merge tag 'trace-tools-v6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing tooling updates from Steven Rostedt: - Add cgroup support for rtla via the -C option - Add --house-keeping option that tells rtla where to place the housekeeping threads - Have rtla/timerlat have its own tracing instance instead of using the top level tracing instance that is the default for other tracing users to use - Add auto analysis to timerlat_hist - Have rtla start the tracers after creating the instances - Reduce rtla hwnoise down to 75% from 100% as it runs with preemption disabled and can cause system instability at 100% - Add support to run timerlat_top and timerlat_hist threads in user-space instead of just using the kernel tasks - Some minor clean ups and documentation changes * tag 'trace-tools-v6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: Documentation: Add tools/rtla timerlat -u option documentation rtla/timerlat_hist: Add timerlat user-space support rtla/timerlat_top: Add timerlat user-space support rtla/hwnoise: Reduce runtime to 75% rtla: Start the tracers after creating all instances rtla/timerlat_hist: Add auto-analysis support rtla/timerlat: Give timerlat auto analysis its own instance rtla: Automatically move rtla to a house-keeping cpu rtla: Change monitored_cpus from char * to cpu_set_t rtla: Add --house-keeping option rtla: Add -C cgroup support |

selftests: mptcp: pm_nl_ctl: fix 32-bit support
When using pm_nl_ctl to validate userspace path-manager's behaviours, it was failing on 32-bit architectures ~half of the time. pm_nl_ctl was not reporting any error but the command was not doing what it was expected to do. As a result, the expected linked event was not triggered after and the test failed. This is due to the fact the token given in argument to the application was parsed as an integer with atoi(): in a 32-bit arch, if the number was bigger than INT_MAX, 2147483647 was used instead. This can simply be fixed by using strtoul() instead of atoi(). The errors have been seen "by chance" when manually looking at the results from LKFT. Fixes: |

selftests: mptcp: depend on SYN_COOKIES
MPTCP selftests are using TCP SYN Cookies for quite a while now, since
v5.9.
Some CIs don't have this config option enabled and this is causing
issues in the tests:
# ns1 MPTCP -> ns1 (10.0.1.1:10000 ) MPTCP (duration 167ms) sysctl: cannot stat /proc/sys/net/ipv4/tcp_syncookies: No such file or directory
# [ OK ]./mptcp_connect.sh: line 554: [: -eq: unary operator expected
There is no impact in the results but the test is not doing what it is
supposed to do.

selftests: mptcp: sockopt: return error if wrong mark
When an error was detected when checking the marks, a message was
correctly printed mentioning the error but followed by another one
saying everything was OK and the selftest was not marked as failed as
expected.
Now the 'ret' variable is directly set to 1 in order to make sure the
exit is done with an error, similar to what is done in other functions.
While at it, the error is correctly propagated to the caller.

IPTables commands using 'iptables-nft' fail on old kernels, at least
on v5.15 because it doesn't see the default IPTables chains:

As a first step before switching to NFTables, we can use iptables-legacy
if available.
