2025-08-14selftests/tc-testing: Check backlog stats in gso_skb caseWilliam Liu
Add tests to ensure proper backlog accounting in hhf, codel, pie, fq, fq_pie, and fq_codel qdiscs. We check for the bug pattern originally found in fq, fq_pie, and fq_codel, which was an underflow in the tbf parent backlog stats upon child qdisc removal.

2025-08-14selftests: drv-net: wait for carrierJakub Kicinski
On fast machines the tests run in quick succession so even when tests clean up after themselves the carrier may need some time to come back. Specifically in NIPA when ping.py runs right after netpoll_basic.py the first ping command fails. Since the context manager callbacks are now common NetDrvEpEnv gets an ip link up call as well.

For kernel itself this can be built with scripts/gen_compile_commands.py, but other projects (e.g., libbpf, or BPF selftests) can benefit from their own compilation database file, which can be generated successfully using external tools, like bear [0].

2025-08-12selftests: drv-net: don't assume device has only 2 queuesJakub Kicinski
The test is implicitly assuming the device only has 2 queues. A real device will likely have more. The exact problem is that because NAPIs get added to the list from the head, the netlink dump reports them in reverse order. So the naive napis[0] will actually likely give us the _last_ NAPI, not the first one. Re-enable all the NAPIs instead of hard-coding 2 in the test. This way the NAPIs we operated on will always reappear, doesn't matter where they were in the registration order.

2025-08-11selftests/net: Ensure assert() triggers in psock_tpacket.cWake Liu
The get_next_frame() function in psock_tpacket.c was missing a return statement in its default switch case, leading to a compiler warning. This was caused by a `bug_on(1)` call, which is defined as an `assert()`, being compiled out because NDEBUG is defined during the build. Instead of adding a `return NULL;` which would silently hide the error and could lead to crashes later, this change restores the original author's intent. By adding `#undef NDEBUG` before including <assert.h>, we ensure the assertion is active and will cause the test to abort if this unreachable code is ever executed.

2025-08-11selftests/net: Replace non-standard __WORDSIZE with sizeof(long) * 8Wake Liu
The `__WORDSIZE` macro, defined in the non-standard `<bits/wordsize.h>` header, is a GNU extension and not universally available with all toolchains, such as Clang when used with musl libc. This can lead to build failures in environments where this header is missing. The intention of the code is to determine the bit width of a C `long`. Replace the non-portable `__WORDSIZE` with the standard and portable `sizeof(long) * 8` expression to achieve the same result. This change also removes the inclusion of the now-unused `<bits/wordsize.h>` header. Signed-off-by: Wake Liu <wakel@google.com> Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2025-08-11tools/sched_ext: Receive updates from SCX repoAndrea Righi
Receive tools/sched_ext updates form https://github.com/sched-ext/scx to sync userspace bits: - basic BPF arena allocator abstractions, - additional process flags definitions, - fixed is_migration_disabled() helper, - separate out user_exit_info BPF and user space code. This also fixes the following warning when building the selftests: tools/sched_ext/include/scx/common.bpf.h:550:9: warning: 'likely' macro redefined [-Wmacro-redefined] 550 | #define likely(x) __builtin_expect(!!(x), 1) | ^ Co-developed-by: Cheng-Yang Chou <yphbchou0911@gmail.com> Signed-off-by: Andrea Righi <arighi@nvidia.com> Signed-off-by: Tejun Heo <tj@kernel.org>
2025-08-11selftests/coredump: Remove the read() that fails the testNam Cao
Resolve a conflict between commit 6a68d28066b6 ("selftests/coredump: Fix "socket_detect_userspace_client" test failure") and commit 994dc26302ed ("selftests/coredump: fix build") The first commit adds a read() to wait for write() from another thread to finish. But the second commit removes the write(). Now that the two commits are in the same tree, the read() now gets EOF and the test fails. Remove this read() so that the test passes.

2025-08-11selftests/mount_setattr: add smoke tests for open_tree_attr(2) bugAleksa Sarai
There appear to be no other open_tree_attr(2) tests at the moment, but as a minimal solution just add some additional checks in the existing MOUNT_ATTR_IDMAP tests to make sure that open_tree_attr(2) cannot be used to bypass the tested restrictions that apply to mount_setattr(2).

/sys/devices/system/cpu/intel_uncore_frequency/package_X_die_Y/ may be readable by all, but /sys/devices/system/cpu/intel_uncore_frequency/package_X_die_Y/current_freq_khz may be readable only by root. Non-root turbostat users see complaints in this scenario. Fail probe of the interface if we can't read current_freq_khz.

2025-08-09tools/power turbostat: Fix DMR supportZhang Rui
Together with the RAPL MSRs, there are more MSRs gone on DMR, including PLR (Perf Limit Reasons), and IRTL (Package cstate Interrupt Response Time Limit) MSRs. The configurable TDP info should also be retrieved from TPMI based Intel Speed Select Technology feature. Remove the access of these MSRs for DMR. Improve the DMR platform feature table to make it more readable at the same time.

We have out-grown the ability to use a 64-bit memory location to inventory every possible built-in counter. Leverage the the CPU_SET(3) macros to break this barrier. Also, break the Joules & Watts counters into two, since we can no longer 'or' them together... Signed-off-by: Len Brown <len.brown@intel.com>
