Now that RCU Tasks Trace has been re-implemented in terms of SRCU-fast,
the ->trc_ipi_to_cpu, ->trc_blkd_cpu, ->trc_blkd_node, ->trc_holdout_list,
and ->trc_reader_special task_struct fields are no longer used.
In addition, the rcu_tasks_trace_qs(), rcu_tasks_trace_qs_blkd(),
exit_tasks_rcu_finish_trace(), and rcu_spawn_tasks_trace_kthread(),
show_rcu_tasks_trace_gp_kthread(), rcu_tasks_trace_get_gp_data(),
rcu_tasks_trace_torture_stats_print(), and get_rcu_tasks_trace_gp_kthread()
functions and all the other functions that they invoke are no longer used.
Also, the TRC_NEED_QS and TRC_NEED_QS_CHECKED CPP macros are no longer used.
Neither are the rcu_tasks_trace_lazy_ms and rcu_task_ipi_delay rcupdate
module parameters and the TASKS_TRACE_RCU_READ_MB Kconfig option.
This commit therefore removes all of them.

The order of the variables in the printf() doesn't match the text and
therefore veristat prints something like this:
Done. Processed 24 files, 0 programs. Skipped 62 files, 0 programs.
When it should print:
Done. Processed 24 files, 62 programs. Skipped 0 files, 0 programs.
Fix the order of variables in the printf() call.

When building kselftests with a toolchain that enables source
fortification (e.g., Android's build environment, which uses
-D_FORTIFY_SOURCE=3), a build failure occurs in tests that use an
empty FIXTURE().
The root cause is that an empty fixture struct results in
`sizeof(self_private)` evaluating to 0. The compiler's fortification
checks then detect the `memset()` call with a compile-time constant size
of 0, issuing a `-Wuser-defined-warnings` which is promoted to an error
by `-Werror`.
An initial attempt to guard the call with `if (sizeof(self_private) > 0)`
was insufficient. The compiler's static analysis is aggressive enough
to flag the `memset(..., 0)` pattern before evaluating the conditional,
thus still triggering the error.
To resolve this robustly, this change introduces a `static inline`
helper function, `__kselftest_memset_safe()`. This function wraps the
size check and the `memset()` call. By replacing the direct `memset()`
in the `__TEST_F_IMPL` macro with a call to this helper, we create an
abstraction boundary. This prevents the compiler's static analyzer from
"seeing" the problematic pattern at the macro expansion site, resolving
the build failure.
Build Context:
Compiler: Android (14488419, +pgo, +bolt, +lto, +mlgo, based on r584948) clang version 22.0.0 (https://android.googlesource.com/toolchain/llvm-project 2d65e4108033380e6fe8e08b1f1826cd2bfb0c99)

'available_events' is actually not required by
'test.d/event/toplevel-enable.tc' and its Existence has been tested in
'test.d/00basic/basic4.tc'.
So the require of 'available_events' can be dropped and then we can add
'instance' flag to test 'test.d/event/toplevel-enable.tc' for instance.
Test result show as below:
# ./ftracetest test.d/event/toplevel-enable.tc

The func_traceonoff_triggers.tc sometimes goes to fail
on my board, Kunpeng-920.
[root@localhost]# ./ftracetest ./test.d/ftrace/func_traceonoff_triggers.tc -l fail.log
=== Ftrace unit tests ===
[1] ftrace - test for function traceon/off triggers [FAIL]
[2] (instance) ftrace - test for function traceon/off triggers [UNSUPPORTED]
I look up the log, and it shows that the md5sum is different between csum1 and csum2.
++ cnt=611
++ sleep .1
+++ cnt_trace
+++ grep -v '^#' trace
+++ wc -l
++ cnt2=611
++ '[' 611 -ne 611 ']'
+++ cat tracing_on
++ on=0
++ '[' 0 '!=' 0 ']'
+++ md5sum trace
++ csum1='76896aa74362fff66a6a5f3cf8a8a500 trace'
++ sleep .1
+++ md5sum trace
++ csum2='ee8625a21c058818fc26e45c1ed3f6de trace'
++ '[' '76896aa74362fff66a6a5f3cf8a8a500 trace' '!=' 'ee8625a21c058818fc26e45c1ed3f6de trace' ']'
++ fail 'Tracing file is still changing'
++ echo Tracing file is still changing
Tracing file is still changing
++ exit_fail
++ exit 1
So I directly dump the trace file before md5sum, the diff shows that:

Recent changes in BTF generation [1] rely on ${OBJCOPY} command to
update .BTF_ids section data in target ELF files.
This exposed a bug in llvm-objcopy --update-section code path, that
may lead to corruption of a target ELF file. Specifically, because of
the bug st_shndx of some symbols may be (incorrectly) set to 0xffff
(SHN_XINDEX) [2][3].
While there is a pending fix for LLVM, it'll take some time before it
lands (likely in 22.x). And the kernel build must keep working with
older LLVM toolchains in the foreseeable future.
Using GNU objcopy for .BTF_ids update would work, but it would require
changes to LLVM-based build process, likely breaking existing build
environments as discussed in [2].
To work around llvm-objcopy bug, implement --patch_btfids code path in
resolve_btfids as a drop-in replacement for:
${OBJCOPY} --update-section .BTF_ids=${btf_ids} ${elf}
Which works specifically for .BTF_ids section:
${RESOLVE_BTFIDS} --patch_btfids ${btf_ids} ${elf}
This feature in resolve_btfids can be removed at some point in the
future, when llvm-objcopy with a relevant bugfix becomes common.

The test case first initializes 9 stack slots as STACK_MISC,
then conditionally updates each of them to SCALAR spill inside an
iterator based loop. This leads to 2**9 combinations of MISC/SPILL
marks for these slots at the iterator next call.
The loop converges only if the verifier treats such states as
equivalent, otherwise visited states are evicted from the states cache
too quickly.

Test for state graph backedges accumulation for SCCs formed by
bpf_loop(). Equivalent to the following C program:
int main(void) {
1: fp[-8] = bpf_get_prandom_u32();
2: fp[-16] = -32; // used in a memory access below
3: bpf_loop(7, loop_cb4, fp, 0);
4: return 0;
}
int loop_cb4(int i, void *ctx) {
5: if (unlikely(ctx[-8] > bpf_get_prandom_u32()))
6: *(u64 *)(fp + ctx[-16]) = 42; // aligned access expected
7: if (unlikely(fp[-8] > bpf_get_prandom_u32()))
8: ctx[-16] = -31; // makes said access unaligned
9: return 0;
}
If state graph backedges are not accumulated properly at the SCC
formed by loop_cb4() call from bpf_loop(), the state {ctx[-16]=-32}
injected at instruction 9 on verification path 1,2,3,5,7,9,4 would be
considered fully verified and would lack precision mark for ctx[-16].
This would lead to early pruning of verification path 1,2,3,5,7,8,9 in
state {ctx[-16]=-31}, which in turn leads to the incorrect assumption
that the above program is safe.

ptrace_test.c currently contains a duplicated version of the
scoped_domains fixture variants. This patch removes that and make it use
the shared scoped_base_variants.h instead, like in
scoped_abstract_unix_test and scoped_signal_test.
This required renaming the hierarchy fixture to scoped_domains, but the
test is otherwise the same.

Add missing semicolon after EXPECT_EQ(0, close(stream_server_child)) in

the close statement after the line, but this causes no observable

Add test_generic_15.sh to verify that async partition scan prevents
IO hang when reading partition tables.
The test creates ublk devices with fault_inject target and very large
delay (60s) to simulate blocked partition table reads, then kills the
daemon to verify proper state transitions without hanging:
1. Without recovery support:
- Create device with fault_inject and 60s delay
- Kill daemon while partition scan may be blocked
- Verify device transitions to DEAD state
2. With recovery support (-r 1):
- Create device with fault_inject, 60s delay, and recovery
- Kill daemon while partition scan may be blocked
- Verify device transitions to QUIESCED state
Before the async partition scan fix, killing the daemon during
partition scan would cause deadlock as partition scan held ub->mutex
while waiting for IO. With the async fix, partition scan happens in
a work function and flush_work() ensures proper synchronization.
Add _add_ublk_dev_no_settle() helper function to skip udevadm settle,
which would otherwise hang waiting for partition scan events to
complete when partition table read is delayed.

The recent introduction of the libopenssl feature test forgot to add the
-lssl to the test-all.o target, which made it always fail, fix it.
Noticed by looking at this file after building:
$ cat /tmp/build/perf-tools/feature/test-all.make.output
/usr/bin/ld: /tmp/ccBhO8WH.ltrans0.ltrans.o: in function `main':
/home/acme/git/perf-tools/tools/build/feature/test-libopenssl.c:6:(.text.startup+0x2ed): undefined reference to `OPENSSL_init_ssl'
collect2: error: ld returned 1 exit status
$
It was added only to the individual ssl test, that works:
$ cat /tmp/build/perf-tools/feature/test-libopenssl.make.output
$ ldd /tmp/build/perf-tools/feature/test-libopenssl.bin | grep ssl
libssl.so.3 => /usr/lib64/libssl.so.3 (0x00007fb81eda8000)

The size of Unix pathname addresses is computed in selftests using
offsetof(struct sockaddr_un, sun_path) + strlen(xxx). It should have
been that +1, which makes addresses passed to the libc and kernel
non-NULL-terminated. unix_mkname_bsd() fixes that in Linux so there is
no harm, but just using sizeof(the address struct) should improve
readability.

Remove bind() call on a client socket that doesn't make sense.
Since strlen(cli_un.sun_path) returns a random value depending on stack
garbage, that many uninitialized bytes are read from the stack as an
unix socket address. This creates random test failures due to the bind
address being invalid or already in use if the same stack value comes up
twice.

connect_variant(unspec_any0) is called twice. Both calls end
up in connect_variant_addrlen() with an address length of
get_addrlen(minimal=false).
However, the connect() syscall and its variants (e.g.
iouring/compat) accept much shorter addresses of 4 bytes
and that behaviour was not tested.
Replace one of these calls with one using a minimal address
length (just a bare sa_family=AF_UNSPEC field with no actual
address). Also add a call using a truncated address for good
measure.

The nominal error code for bind(AF_UNSPEC) on an IPv6 socket
is -EAFNOSUPPORT, not -EINVAL. -EINVAL is only returned when
the supplied address struct is too short, which happens to be
the case in current selftests because they treat AF_UNSPEC
like IPv4 sockets do: as an alias for AF_INET (which is a
16-byte struct instead of the 24 bytes required by IPv6
sockets).
Make the union large enough for any address (by adding struct
sockaddr_storage to the union), and make AF_UNSPEC addresses
large enough for any family.
Test for -EAFNOSUPPORT instead, and add a dedicated test case
for truncated inputs with -EINVAL.
