2021-01-15kunit: tool: fix minor typing issue with None statusDaniel Latypov1-9/+8
The code to handle aggregating statuses didn't check that the status actually got set to some non-None value. Default the value to SUCCESS instead of adding a bunch of `is None` checks. This sorta follows the precedent in commit 3fc48259d525 ("kunit: Don't fail test suites if one of them is empty"). Also slightly simplify the code and add type annotations.

2021-01-15kunit: tool: surface and address more typing issuesDaniel Latypov5-52/+54
The authors of this tool were more familiar with a different type-checker, https://github.com/google/pytype. That's open source, but mypy seems more prevalent (and runs faster). And unlike pytype, mypy doesn't try to infer types so it doesn't check unanotated functions. So annotate ~all functions in kunit tool to increase type-checking coverage. Note: per https://www.python.org/dev/peps/pep-0484/, `__init__()` should be annotated as `-> None`. Doing so makes mypy discover a number of new violations. Exclude main() since we reuse `request` for the different types of requests, which mypy isn't happy about. This commit fixes all but one error, where `TestSuite.status` might be None.

2021-01-14bpf: Add tests for new BPF atomic operationsBrendan Jackman9-0/+881
The prog_test that's added depends on Clang/LLVM features added by Yonghong in commit 286daafd6512 (was https://reviews.llvm.org/D72184). Note the use of a define called ENABLE_ATOMICS_TESTS: this is used to: - Avoid breaking the build for people on old versions of Clang - Avoid needing separate lists of test objects for no_alu32, where atomics are not supported even if Clang has the feature. The atomics_test.o BPF object is built unconditionally both for test_progs and test_progs-no_alu32. For test_progs, if Clang supports atomics, ENABLE_ATOMICS_TESTS is defined, so it includes the proper test code. Otherwise, progs and global vars are defined anyway, as stubs; this means that the skeleton user code still builds. The atomics_test.o userspace object is built once and used for both test_progs and test_progs-no_alu32. A variable called skip_tests is defined in the BPF object's data section, which tells the userspace object whether to skip the atomics test.

A subsequent patch will add additional atomic operations. These new operations will use the same opcode field as the existing XADD, with the immediate discriminating different operations. In preparation, rename the instruction mode BPF_ATOMIC and start calling the zero immediate BPF_ADD. This is possible (doesn't break existing valid BPF progs) because the immediate field is currently reserved MBZ and BPF_ADD is zero. All uses are removed from the tree but the BPF_XADD definition is kept around to avoid breaking builds for people including kernel headers.

2021-01-12selftests/bpf: Sync RCU before unloading bpf_testmodAndrii Nakryiko3-33/+12
If some of the subtests use module BTFs through ksyms, they will cause bpf_prog to take a refcount on bpf_testmod module, which will prevent it from successfully unloading. Module's refcnt is decremented when bpf_prog is freed, which generally happens in RCU callback. So we need to trigger syncronize_rcu() in the kernel, which can be achieved nicely with membarrier(MEMBARRIER_CMD_SHARED) or membarrier(MEMBARRIER_CMD_GLOBAL) syscall. So do that in kernel_sync_rcu() and make it available to other test inside the test_progs. This synchronize_rcu() is called before attempting to unload bpf_testmod.

2021-01-12bpf: Update local storage test to check handling of null ptrsKP Singh2-97/+61
It was found in [1] that bpf_inode_storage_get helper did not check the nullness of the passed owner ptr which caused an oops when dereferenced. This change incorporates the example suggested in [1] into the local storage selftest. The test is updated to create a temporary directory instead of just using a tempfile. In order to replicate the issue this copied rm binary is renamed tiggering the inode_rename with a null pointer for the new_inode. The logic to verify the setting and deletion of the inode local storage of the old inode is also moved to this LSM hook. The change also removes the copy_rm function and simply shells out to copy files and recursively delete directories and consolidates the logic of setting the initial inode storage to the bprm_committed_creds hook and removes the file_open hook.

2021-01-09selftests: mptcp: add set_flags command in pm_nl_ctlGeliang Tang1-1/+86
This patch added the set_flags command in pm_nl_ctl, currently we can only set two flags: backup and nobackup. The set_flags command can be used like this: # pm_nl_ctl set 10.0.0.1 flags backup # pm_nl_ctl set 10.0.0.1 flags nobackup Signed-off-by: Geliang Tang <[email protected]> Signed-off-by: Mat Martineau <[email protected]> Signed-off-by: Jakub Kicinski <[email protected]>
2021-01-09selftests: mptcp: add testcases for setting the address IDGeliang Tang1-2/+39
Since the address ID can be set from user-space, some of the tests in pm_netlink.sh will fail. This patch fixed the failures, and add the testcases for setting the address ID.

2021-01-07KVM: selftests: Implement perf_test_util more conventionallyAndrew Jones6-146/+166
It's not conventional C to put non-inline functions in header files. Create a source file for the functions instead. Also reduce the amount of globals and rename the functions to something less generic.
