2024-09-05selftests/bpf: Add config.riscv64Pu Lehui

2024-09-05selftests/bpf: Enable cross platform testing for vmtestPu Lehui
Add support cross platform testing for vmtest. The variable $ARCH in the current script is platform semantics, not kernel semantics. Rename it to $PLATFORM so that we can easily use $ARCH in cross-compilation. And drop `set -u` unbound variable check as we will use CROSS_COMPILE env variable. For now, Using PLATFORM= and CROSS_COMPILE= options will enable cross platform testing: PLATFORM=<platform> CROSS_COMPILE=<toolchain> vmtest.sh -- ./test_progs Tested-by: Eduard Zingerman <eddyz87@gmail.com> Signed-off-by: Pu Lehui <pulehui@huawei.com> Link: https://lore.kernel.org/r/20240905081401.1894789-7-pulehui@huaweicloud.com Signed-off-by: Alexei Starovoitov <ast@kernel.org>

2024-09-05selftests/bpf: Rename fallback in bpf_dctcp to avoid naming conflictPu Lehui
Recently, when compiling bpf selftests on RV64, the following compilation failure occurred: progs/bpf_dctcp.c:29:21: error: redefinition of 'fallback' as different kind of symbol 29 | volatile const char fallback[TCP_CA_NAME_MAX]; | ^ /workspace/tools/testing/selftests/bpf/tools/include/vmlinux.h:86812:15: note: previous definition is here 86812 | typedef u32 (*fallback)(u32, const unsigned char *, size_t); The reason is that the `fallback` symbol has been defined in arch/riscv/lib/crc32.c, which will cause symbol conflicts when vmlinux.h is included in bpf_dctcp. Let we rename `fallback` string to `fallback_cc` in bpf_dctcp to fix this compilation failure.

2024-09-05perf/uprobe: split uprobe_unregister()Peter Zijlstra
With uprobe_unregister() having grown a synchronize_srcu(), it becomes fairly slow to call. Esp. since both users of this API call it in a loop. Peel off the sync_srcu() and do it once, after the loop. We also need to add uprobe_unregister_sync() into uprobe_register()'s error handling path, as we need to be careful about returning to the caller before we have a guarantee that partially attached consumer won't be called anymore. This is an unlikely slow path and this should be totally fine to be slow in the case of a failed attach.

2024-09-04sched_ext: Add cgroup supportTejun Heo
Add sched_ext_ops operations to init/exit cgroups, and track task migrations and config changes. A BPF scheduler may not implement or implement only subset of cgroup features. The implemented features can be indicated using %SCX_OPS_HAS_CGOUP_* flags. If cgroup configuration makes use of features that are not implemented, a warning is triggered. While a BPF scheduler is being enabled and disabled, relevant cgroup operations are locked out using scx_cgroup_rwsem. This avoids situations like task prep taking place while the task is being moved across cgroups, making things easier for BPF schedulers. v7: - cgroup interface file visibility toggling is dropped in favor just warning messages. Dynamically changing interface visiblity caused more confusion than helping. v6: - Updated to reflect the removal of SCX_KF_SLEEPABLE. - Updated to use CONFIG_GROUP_SCHED_WEIGHT and fixes for !CONFIG_FAIR_GROUP_SCHED && CONFIG_EXT_GROUP_SCHED. v5: - Flipped the locking order between scx_cgroup_rwsem and cpus_read_lock() to avoid locking order conflict w/ cpuset. Better documentation around locking. - sched_move_task() takes an early exit if the source and destination are identical. This triggered the warning in scx_cgroup_can_attach() as it left p->scx.cgrp_moving_from uncleared. Updated the cgroup migration path so that ops.cgroup_prep_move() is skipped for identity migrations so that its invocations always match ops.cgroup_move() one-to-one. v4: - Example schedulers moved into their own patches. - Fix build failure when !CONFIG_CGROUP_SCHED, reported by Andrea Righi. v3: - Make scx_example_pair switch all tasks by default. - Convert to BPF inline iterators. - scx_bpf_task_cgroup() is added to determine the current cgroup from CPU controller's POV. This allows BPF schedulers to accurately track CPU cgroup membership. - scx_example_flatcg added. This demonstrates flattened hierarchy implementation of CPU cgroup control and shows significant performance improvement when cgroups which are nested multiple levels are under competition. v2: - Build fixes for different CONFIG combinations.

2024-09-04selftests: mm: make protection_keys test work on arm64Joey Gouly
The encoding of the pkey register differs on arm64, than on x86/ppc. On those platforms, a bit in the register is used to disable permissions, for arm64, a bit enabled in the register indicates that the permission is allowed. This drops two asserts of the form: assert(read_pkey_reg() <= orig_pkey_reg); Because on arm64 this doesn't hold, due to the encoding. The pkey must be reset to both access allow and write allow in the signal handler. pkey_access_allow() works currently for PowerPC as the PKEY_DISABLE_ACCESS and PKEY_DISABLE_WRITE have overlapping bits set. Access to the uc_mcontext is abstracted, as arm64 has a different structure.

2024-09-03selftests/damon: add access_memory_even to .gitignoreSeongJae Park
Patch series "misc fixups for DAMON {self,kunit} tests". This patchset is for minor fixups of DAMON selftests and kunit tests. First three patches make DAMON selftests more cleanly maintained (patches 1 and 2) without unnecessary warnings (patch 3). Following six patches remove unnecessary test case (patch 4), handle configs combinations that can make tests fail (patches 5-7), reorganize the test files following the new guideline (patch 8), and add reference kunitconfig for DAMON kunit tests (patch 9). This patch (of 9): DAMON selftests build access_memory_even, but its not on the .gitignore list. Add it to make 'git status' output cleaner.

2024-09-03selftests/mm: fix charge_reserved_hugetlb.sh testDavid Hildenbrand
Currently, running the charge_reserved_hugetlb.sh selftest we can sometimes observe something like: $ ./charge_reserved_hugetlb.sh -cgroup-v2 ... write_result is 0 After write: hugetlb_usage=0 reserved_usage=10485760 killing write_to_hugetlbfs Received 2. Deleting the memory Detach failure: Invalid argument umount: /mnt/huge: target is busy. Both cases are issues in the test. While the unmount error seems to be racy, it will make the test fail: $ ./run_vmtests.sh -t hugetlb ... # [FAIL] not ok 10 charge_reserved_hugetlb.sh -cgroup-v2 # exit=32 The issue is that we are not waiting for the write_to_hugetlbfs process to quit. So it might still have a hugetlbfs file open, about which umount is not happy. Fix that by making "killall" wait for the process to quit. The other error ("Detach failure: Invalid argument") does not seem to result in a test error, but is misleading. Turns out write_to_hugetlbfs.c unconditionally tries to cleanup using shmdt(), even when we only mmap()'ed a hugetlb file. Even worse, shmaddr is never even set for the SHM case. Fix that as well. With this change it seems to work as expected.

Most of the time, the number of sent SYN+MPJ is the same as the received ones. But sometimes, there are more, because there are dropped, or there are errors.

2024-09-03selftests: netfilter: nft_queue.sh: fix spurious timeout on debug kernelFlorian Westphal
The sctp selftest is very slow on debug kernels. Its possible that the nf_queue listener program exits due to timeout before first sctp packet is processed. In this case socat hangs until script times out. Fix this by removing the -t option where possible and kill the test program once the file transfer/socat has exited. -t sets SO_RCVTIMEO, its inteded for the 'ping' part of the selftest where we want to make sure that packets get reinjected properly without skipping a second queue request. While at it, add a helper to compare the (binary) files instead of diff. The 'diff' part was copied from a another sub-test that compares text. Let helper dump file sizes on error so we can see the progress made. Tested on an old 2010-ish box with a debug kernel and 100 iterations. This is a followup to the earlier filesize reduction change.
