We have to resort to a bit of a hack: python-libevdev gets the
properties from libevdev at module init time. If libevdev hasn't been
rebuilt with the new property it won't be automatically populated. So we
hack around this by constructing the property manually.

Instead of multiple spellings of a string-provided argument, let's make
this a tad more type-safe and use an enum here.
And while we do this fix the two wrong devices:
- elan_04f3_313a (HP ZBook Fury 15) is discrete button pad
- dell_044e_1220 (Dell Precision 7740) is a discrete button pad

Not all our tests really require it but since it's likely pip-installed
anyway it's trivial to require the new version, just in case we want to

Similar to commit 835a50753579 ("selftests/bpf: Add -fms-extensions to
bpf build flags") and commit 639f58a0f480 ("bpftool: Fix build warnings
due to MS extensions")
The kernel is now built with -fms-extensions, therefore
generated vmlinux.h contains types like:
struct slab {
..
struct freelist_counters;
};
Use -fms-extensions and -Wno-microsoft-anon-tag flags
to build bpf programs that #include "vmlinux.h"

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:

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.

Commit 48e126777386 ("sched_ext: Introduce scx_sched") introduced
scx_root and removed scx_ops, causing scx_show_state.py to fail when
searching for the 'scx_ops' object. [1]
Fix by using 'scx_root' instead, with NULL pointer handling.

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)

Drop the <uapi/linux/types.h> includes now that <linux/types.h>
(tools/include/linux/types.h) has a definition for __aligned_le64, which
is needed by <linux/iommufd.h>.
Including <uapi/linux/types.h> is harmless but causes benign typedef
redefinitions. This is not a problem for VFIO selftests but becomes an
issue when the VFIO selftests library is built into KVM selftests, since
they are built with -std=gnu99 which does not allow typedef redifitions.
No functional change intended.

In the thread_state_get() function, the logic to find the thread's state
character was using `sizeof(header) - 1` to calculate the offset from the
"State:\t" string.
The `header` variable is a `const char *` pointer. `sizeof()` on a
pointer returns the size of the pointer itself, not the length of the
string literal it points to. This makes the code's behavior dependent on
the architecture's pointer size.
This bug was identified on a 32-bit ARM build (`gsi_tv_arm`) for Android,
running on an ARMv8-based device, compiled with Clang 19.0.1.
On this 32-bit architecture, `sizeof(char *)` is 4. The expression
`sizeof(header) - 1` resulted in an incorrect offset of 3, causing the
test to read the wrong character from `/proc/[tid]/status` and fail.
On 64-bit architectures, `sizeof(char *)` is 8, so the expression
coincidentally evaluates to 7, which matches the length of "State:\t".
This is why the bug likely remained hidden on 64-bit builds.
To fix this and make the code portable and correct across all
architectures, this patch replaces `sizeof(header) - 1` with
`strlen(header)`. The `strlen()` function correctly calculates the
string's length, ensuring the correct offset is always used.
