2025-02-08selftests/mm: build with -O2Kevin Brodsky1-1/+8
commit 46036188ea1f5266df23a6149dea0df1c77cd1c7 upstream. The mm kselftests are currently built with no optimisation (-O0). It's unclear why, and besides being obviously suboptimal, this also prevents the pkeys tests from working as intended. Let's build all the tests with -O2.

2025-02-08ktest.pl: Check kernelrelease return in get_versionRicardo B. Marliere1-0/+5
commit a4e17a8f239a545c463f8ec27db4ed6e74b31841 upstream. In the case of a test that uses the special option ${KERNEL_VERSION} in one of its settings but has no configuration available in ${OUTPUT_DIR}, for example if it's a new empty directory, then the `make kernelrelease` call will fail and the subroutine will chomp an empty string, silently. Fix that by adding an empty configuration and retrying.

2025-02-08selftests/ftrace: Fix to use remount when testing mount GID optionMasami Hiramatsu (Google)1-4/+4
commit 159ca65c42d90d5ab98fc31b708b12c0be2c26e0 upstream. Fix mount_options.tc to use remount option to mount the tracefs. Since the current implementation does not umount the tracefs, this test always fails because of -EBUSY error. Using remount option will allow us to change the mount option.

2025-02-08selftests/rseq: Fix handling of glibc without rseq supportMathieu Desnoyers2-8/+33
commit 336d02bc4c6bec5c3d933e5d470a94970f830957 upstream. When porting librseq commit: commit c7b45750fa85 ("Adapt to glibc __rseq_size feature detection") from librseq to the kernel selftests, the following line was missed at the end of rseq_init(): rseq_size = get_rseq_kernel_feature_size(); which effectively leaves rseq_size initialized to -1U when glibc does not have rseq support. glibc supports rseq from version 2.35 onwards. In a following librseq commit commit c67d198627c2 ("Only set 'rseq_size' on first thread registration") to mimic the libc behavior, a new approach is taken: don't set the feature size in 'rseq_size' until at least one thread has successfully registered. This allows using 'rseq_size' in fast-paths to test for both registration status and available features. The caveat is that on libc either all threads are registered or none are, while with bare librseq it is the responsability of the user to register all threads using rseq. This combines the changes from the following librseq git commits: commit c7b45750fa85 ("Adapt to glibc __rseq_size feature detection") commit c67d198627c2 ("Only set 'rseq_size' on first thread registration") Fixes: a0cc649353bb ("selftests/rseq: Fix mm_cid test failure") Reported-by: Raghavendra Rao Ananta <rananta@google.com> Signed-off-by: Mathieu Desnoyers <mathieu.desnoyers@efficios.com> Cc: Raghavendra Rao Ananta <rananta@google.com> Cc: Shuah Khan <skhan@linuxfoundation.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Boqun Feng <boqun.feng@gmail.com> Cc: "Paul E.

2025-02-08selftests/bpf: Fix fill_link_info selftest on powerpcSaket Kumar Bhaskar2-3/+14
[ Upstream commit 4d33dc1bc31df80356c49e40dbd3ddff19500bcb ] With CONFIG_KPROBES_ON_FTRACE enabled on powerpc, ftrace_location_range returns ftrace location for bpf_fentry_test1 at offset of 4 bytes from function entry. This is because branch to _mcount function is at offset of 4 bytes in function profile sequence. To fix this, add entry_offset of 4 bytes while verifying the address for kprobe entry address of bpf_fentry_test1 in verify_perf_link_info in selftest, when CONFIG_KPROBES_ON_FTRACE is enabled. Disassemble of bpf_fentry_test1: c000000000e4b080 <bpf_fentry_test1>: c000000000e4b080: a6 02 08 7c mflr r0 c000000000e4b084: b9 e2 22 4b bl c00000000007933c <_mcount> c000000000e4b088: 01 00 63 38 addi r3,r3,1 c000000000e4b08c: b4 07 63 7c extsw r3,r3 c000000000e4b090: 20 00 80 4e blr When CONFIG_PPC_FTRACE_OUT_OF_LINE [1] is enabled, these function profile sequence is moved out of line with an unconditional branch at offset 0.

2025-01-13selftests/mm: set allocated memory to non-zero content in cow testRyan Roberts1-4/+4
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.

Over the last two weeks we gathered only around two-thirds of our normal weekly fix count, but delaying sending these until -rc7 seemed like a really bad idea. AFAIK we have no bugs under investigation. One or two reverts for stuff for which we haven't gotten a proper fix will likely come in the next PR.

2024-12-31selftests/memfd: add test for mapping write-sealed memfd read-onlyLorenzo Stoakes1-0/+43
Now we have reinstated the ability to map F_SEAL_WRITE mappings read-only, assert that we are able to do this in a test to ensure that we do not regress this again.

2024-12-25sched_ext: Fix dsq_local_on selftestTejun Heo2-3/+7
The dsp_local_on selftest expects the scheduler to fail by trying to schedule an e.g. CPU-affine task to the wrong CPU. However, this isn't guaranteed to happen in the 1 second window that the test is running. Besides, it's odd to have this particular exception path tested when there are no other tests that verify that the interface is working at all - e.g. the test would pass if dsp_local_on interface is completely broken and fails on any attempt. Flip the test so that it verifies that the feature works. While at it, fix a typo in the info message.
