2025-04-11selftests/tc-testing: Add test for echo of big TC filtersToke Høiland-Jørgensen
Add a selftest that checks whether the kernel can successfully echo a big tc filter, to test the fix introduced in commit: 369609fc6272 ("tc: Ensure we have enough buffer space when sending filter netlink notifications") Signed-off-by: Toke Høiland-Jørgensen <toke@redhat.com> Tested-by: Victor Nogueira <victor@mojatatu.com> Link: https://patch.msgid.link/20250410104322.214620-1-toke@redhat.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2025-04-11tracing/selftest: Add test to better test subops filtering of function graphSteven Rostedt
A bug was discovered that showed the accounting of the subops of the ftrace_ops filtering was incorrect. Add a new test to better test the filtering. This test creates two instances, where it will add various filters to both the set_ftrace_filter and the set_ftrace_notrace files and enable function_graph. Then it looks into the enabled_functions file to make sure that the filters are behaving correctly.

2025-04-11perf tools: Remove evsel__handle_error_quirks()Namhyung Kim
The evsel__handle_error_quirks() is to fixup invalid event attributes on some architecture based on the error code. Currently it's only used for AMD to disable precise_ip not to use IBS which has more restrictions. But the commit c33aea446bf555ab changed call evsel__precise_ip_fallback for any errors so there's no difference with the above function. To make matter worse, it caused a problem with branch stack on Zen3. The IBS doesn't support branch stack so it should use a regular core PMU event. The default event is set precise_max and it starts with 3. And evsel__precise_ip_fallback() tries with it and reduces the level one by one. At last it tries with 0 but it also failed on Zen3 since the branch stack is not supported for the cycles event. At this point, evsel__precise_ip_fallback() restores the original precise_ip value (3) in the hope that it can succeed with other modifier (like exclude_kernel). Then evsel__handle_error_quirks() see it has precise_ip != 0 and make it retry with 0. This created an infinite loop. Before: $ perf record -b -vv |& grep removing removing precise_ip on AMD removing precise_ip on AMD removing precise_ip on AMD removing precise_ip on AMD removing precise_ip on AMD removing precise_ip on AMD removing precise_ip on AMD removing precise_ip on AMD removing precise_ip on AMD removing precise_ip on AMD removing precise_ip on AMD removing precise_ip on AMD ... After: $ perf record -b true Error: Failure to open event 'cycles:P' on PMU 'cpu' which will be removed. Invalid event (cycles:P) in per-thread mode, enable system wide with '-a'. Error: Failure to open any events for recording.

2025-04-08selftests: mptcp: validate MPJoin HMacFailure countersMatthieu Baerts (NGI0)
The parent commit fixes an issue around these counters where one of them -- MPJoinAckHMacFailure -- was wrongly incremented in some cases. This makes sure the counter is always 0. It should be incremented only in case of corruption, or a wrong implementation, which should not be the case in these selftests.

2025-04-08selftests/mincore: Allow read-ahead pages to reach the end of the fileQiuxu Zhuo
When running the mincore_selftest on a system with an XFS file system, it failed the "check_file_mmap" test case due to the read-ahead pages reaching the end of the file. The failure log is as below: RUN global.check_file_mmap ... mincore_selftest.c:264:check_file_mmap:Expected i (1024) < vec_size (1024) mincore_selftest.c:265:check_file_mmap:Read-ahead pages reached the end of the file check_file_mmap: Test failed FAIL global.check_file_mmap This is because the read-ahead window size of the XFS file system on this machine is 4 MB, which is larger than the size from the #PF address to the end of the file. As a result, all the pages for this file are populated. blockdev --getra /dev/nvme0n1p5 8192 blockdev --getbsz /dev/nvme0n1p5 512 This issue can be fixed by extending the current FILE_SIZE 4MB to a larger number, but it will still fail if the read-ahead window size of the file system is larger enough. Additionally, in the real world, read-ahead pages reaching the end of the file can happen and is an expected behavior. Therefore, allowing read-ahead pages to reach the end of the file is a better choice for the "check_file_mmap" test case.

2025-04-08objtool, xen: Fix INSN_SYSCALL / INSN_SYSRET semanticsJosh Poimboeuf
Objtool uses an arbitrary rule for INSN_SYSCALL and INSN_SYSRET that almost works by accident: if it's in a function, control flow continues after the instruction, otherwise it terminates. That behavior should instead be based on the semantics of the underlying instruction. Change INSN_SYSCALL to always preserve control flow and INSN_SYSRET to always terminate it. The changed semantic for INSN_SYSCALL requires a tweak to the !CONFIG_IA32_EMULATION version of xen_entry_SYSCALL_compat(). In Xen, SYSCALL is a hypercall which usually returns. But in this case it's a hypercall to IRET which doesn't return. Add UD2 to tell objtool to terminate control flow, and to prevent undefined behavior at runtime.

INSN_CONTEXT_SWITCH is ambiguous. It can represent both call semantics (SYSCALL, SYSENTER) and return semantics (SYSRET, IRET, RETS, RETU). Those differ significantly: calls preserve control flow whereas returns terminate it.
