2025-01-14selftests: tmpfs: Add Test-skip if not run as rootShivam Chaudhary
Add 'ksft_exit_skip()', if not run as root, with an appropriate Warning. Add 'ksft_print_header()' and 'ksft_set_plan()' to structure test outputs more effectively. Test logs: Before Change: - Without root error: unshare, errno 1 - With root No, output After change: - Without root TAP version 13 1..1 ok 2 # SKIP This test needs root to run! Totals: pass:0 fail:0 xfail:0 xpass:0 skip:1 error:0 - With root TAP version 13 1..1 Link: https://lore.kernel.org/r/20250105085255.124929-2-cvam0000@gmail.com Signed-off-by: Shivam Chaudhary <cvam0000@gmail.com> Signed-off-by: Shuah Khan <skhan@linuxfoundation.org>
2025-01-14selftests: harness: fix printing of mismatch values in __EXPECT()Dmitry V. Levin
intptr_t and uintptr_t are not big enough types on 32-bit architectures when printing 64-bit values, resulting to the following incorrect diagnostic output: # get_syscall_info.c:209:get_syscall_info:Expected exp_args[2] (3134324433) == info.entry.args[1] (3134324433) Replace intptr_t and uintptr_t with intmax_t and uintmax_t, respectively. With this fix, the same test produces more usable diagnostic output: # get_syscall_info.c:209:get_syscall_info:Expected exp_args[2] (3134324433) == info.entry.args[1] (18446744072548908753) Link: https://lore.kernel.org/r/20250108170757.GA6723@strace.io Fixes: b5bb6d3068ea ("selftests/seccomp: fix 32-bit build warnings") Signed-off-by: Dmitry V.

2025-01-14perf test record+probe_libc_inet_pton: Make test resilientLeo Yan
The test failed back and forth due to the call chain being heavily impacted by the libc, which varies across different architectures and distros. The libc contains the symbols for "gaih_inet" and "getaddrinfo" in some cases, but not always. Moreover, these symbols can be either normal symbols or dynamic symbols, making it difficult to decide the call chain entries due to the symbols are inconsistent. To fix the issue, this commit identifies three call chain entries are always present. These entries are matched by iterating through the lines in the "perf script" result. The recording attribute max-stack is set to 4 for the possible maximum call chain depth.

2025-01-14perf tests base_probe: Fix check for the count of existing probes in ↵Athira Rajeev
test_adding_kernel perftool-testsuite_probe fails in test_adding_kernel as below: Regexp not found: "probe:inode_permission_11" -- [ FAIL ] -- perf_probe :: test_adding_kernel :: force-adding probes :: second probe adding (with force) (output regexp parsing) event syntax error: 'probe:inode_permission_11' \___ unknown tracepoint Error: File /sys/kernel/tracing//events/probe/inode_permission_11 not found. Hint: Perhaps this kernel misses some CONFIG_ setting to enable this feature?. The test does the following: 1) Adds a probe point first using: $CMD_PERF probe --add $TEST_PROBE 2) Then tries to add same probe again without —force and expects it to fail. Next tries to add same probe again with —force. In this case, perf probe succeeds and adds the probe with a suffix number. Example: ./perf probe --add inode_permission Added new event: probe:inode_permission (on inode_permission) ./perf probe --add inode_permission --force Added new event: probe:inode_permission_1 (on inode_permission) ./perf probe --add inode_permission --force Added new event: probe:inode_permission_2 (on inode_permission) Each time, suffix is added to existing probe name. To get the suffix number, test cases uses: NO_OF_PROBES=`$CMD_PERF probe -l | wc -l` This will work if there is no other probe existing in the system. If there are any other probes other than kernel probes or inode_permission, ( example: any probe), "perf probe -l" will include count for other probes too. Example, in the system where this failed, already some probes were default added. So count became 10 ./perf probe -l | wc -l 10 So to be specific for "inode_permission", restrict the probe count check to that probe point alone using: NO_OF_PROBES=`$CMD_PERF probe -l $TEST_PROBE| wc -l` Similarly while removing the probe using "probe --del *", (removing all probes), check uses: ../common/check_all_lines_matched.pl "Removed event: probe:$TEST_PROBE" But if there are other probes in the system, the log will contain reference to other existing probe too. Hence change usage of check_all_lines_matched.pl to check_all_patterns_found.pl This will make sure expecting string comes in the result Signed-off-by: Athira Rajeev <atrajeev@linux.vnet.ibm.com> Acked-by: Veronika Molnarova <vmolnaro@redhat.com> Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: Disha Goel <disgoel@linux.vnet.ibm.com> Cc: Hari Bathini <hbathini@linux.ibm.com> Cc: Ian Rogers <irogers@google.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Kajol Jain <kjain@linux.ibm.com> Cc: Madhavan Srinivasan <maddy@linux.ibm.com> Cc: Michael Petlan <mpetlan@redhat.com> Cc: Namhyung Kim <namhyung@kernel.org> Link: https://lore.kernel.org/r/20250110094324.94604-1-atrajeev@linux.vnet.ibm.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

2025-01-14perf test brstack: Speed up running test by using tr -s instead of xargsJames Clark
The brstack test runs quite slowly in software models. Part of the reason is "xargs -n1" is quite inefficient in replacing spaces with newlines. While that's not noticeable on normal machines, it is on software models. Use "tr -s ' ' '\n'" instead which can do the same transformation, but is much faster. For comparison on an M1 Macbook Pro: $ time seq -s ' ' 10000 | xargs -n1 > /dev/null real 0m2.729s user 0m2.009s sys 0m0.914s $ time seq -s ' ' 10000 | tr -s ' ' '\n' | grep '.' > /dev/null real 0m0.002s user 0m0.001s sys 0m0.001s The "grep '.'" is also needed to remove any remaining blank lines.

2025-01-12selftests/mm: set allocated memory to non-zero content in cow testRyan Roberts
After commit b1f202060afe ("mm: remap unused subpages to shared zeropage when splitting isolated thp"), cow test cases involving swapping out THPs via madvise(MADV_PAGEOUT) started to be skipped due to the subsequent check via pagemap determining that the memory was not actually swapped out. Logs similar to this were emitted: ... # [RUN] Basic COW after fork() ... with swapped-out, PTE-mapped THP (16 kB) ok 2 # SKIP MADV_PAGEOUT did not work, is swap enabled? # [RUN] Basic COW after fork() ... with single PTE of swapped-out THP (16 kB) ok 3 # SKIP MADV_PAGEOUT did not work, is swap enabled? # [RUN] Basic COW after fork() ... with swapped-out, PTE-mapped THP (32 kB) ok 4 # SKIP MADV_PAGEOUT did not work, is swap enabled? ... The commit in question introduces the behaviour of scanning THPs and if their content is predominantly zero, it splits them and replaces the pages which are wholly zero with the zero page. These cow test cases were getting caught up in this. So let's avoid that by filling the contents of all allocated memory with a non-zero value. With this in place, the tests are passing again.
