2023-12-29selftests/mm: log run_vmtests.sh results in TAP formatRyan Roberts1-12/+39
When running tests on a CI system (e.g. LAVA) it is useful to output test results in TAP (Test Anything Protocol) format so that the CI can parse the fine-grained results to show regressions. Many of the mm selftest binaries already output using the TAP format. And the kselftests runner (run_kselftest.sh) also uses the format. CI systems such as LAVA can already handle nested TAP reports. However, with the mm selftests we have 3 levels of nesting (run_kselftest.sh -> run_vmtests.sh -> individual test binaries) and the middle level did not previously support TAP, which breaks the parser. Let's fix that by teaching run_vmtests.sh to output using the TAP format. Ideally this would be opt-in via a command line argument to avoid the possibility of breaking anyone's existing scripts that might scrape the output. However, it is not possible to pass arguments to tests invoked via run_kselftest.sh. So I've implemented an opt-out option (-n), which will revert to the existing output format. Future changes to this file should be aware of 2 new conventions: - output that is part of the TAP reporting is piped through tap_output - general output is piped through tap_prefix Link: https://lkml.kernel.org/r/20231214162434.3580009-1-ryan.roberts@arm.com Signed-off-by: Ryan Roberts <ryan.roberts@arm.com> Reviewed-by: Mark Brown <broonie@kernel.org> Tested-by: John Hubbard <jhubbard@nvidia.com> Cc: Aishwarya TCV <aishwarya.tcv@arm.com> Cc: Peter Xu <peterx@redhat.com> Cc: Shuah Khan <shuah@kernel.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org>
2023-12-29selftests/mm: add UFFDIO_MOVE ioctl testSuren Baghdasaryan3-0/+214
Add tests for new UFFDIO_MOVE ioctl which uses uffd to move source into destination buffer while checking the contents of both after the move. After the operation the content of the destination buffer should match the original source buffer's content while the source buffer should be zeroed. Separate tests are designed for PMD aligned and unaligned cases because they utilize different code paths in the kernel.

2023-12-29selftests/mm: add uffd_test_case_ops to allow test case-specific operationsSuren Baghdasaryan3-0/+22
Currently each test can specify unique operations using uffd_test_ops, however these operations are per-memory type and not per-test. Add uffd_test_case_ops which each test case can customize for its own needs regardless of the memory type being used. Pre- and post-allocation operations are added, some of which will be used in the next patch to implement test-specific operations like madvise after memory is allocated but before it is accessed.

2023-12-29selftests/mm: call uffd_test_ctx_clear at the end of the testSuren Baghdasaryan4-4/+7
uffd_test_ctx_clear() is being called from uffd_test_ctx_init() to unmap areas used in the previous test run. This approach is problematic because while unmapping areas uffd_test_ctx_clear() uses page_size and nr_pages which might differ from one test run to another. Fix this by calling uffd_test_ctx_clear() after each test is done.

2023-12-29RISC-V: KVM: selftests: Treat SBI ext regs like ISA ext regsAndrew Jones2-14/+92
SBI extension registers may not be present and indeed when running on a platform without sscofpmf the PMU SBI extension is not. Move the SBI extension registers from the base set of registers to the filter list. Individual configs should test for any that may or may not be present separately. Since the PMU extension may disappear and the DBCN extension is only present in later kernels, separate them from the rest into their own configs. The rest are lumped together into the same config.

Always use register subtypes in the get-reg-list test when registers have them. The only registers neglecting to do so were ISA extension registers. While we don't really need to use KVM_REG_RISCV_ISA_SINGLE (since it's zero), the main purpose is to avoid confusion and to self-document the tests. Also add print support for the multi registers like SBI extensions have, even though they're only used for debugging.

In some cases the result of test were hidden inside the stdout and it was difficult to identify when a test was skipped and why. List of changes 1. Capitalize all the words that express a test result : "OK", "SKIPPED" and "FAIL". 2. Place all test result text at the end of the message. This will prevent the result from being hidden when stdout is verbose. 3. Any other explanation that comes after the result text will be placed in a new line. 4. All failures are marked as "FAIL" 5. Pipped the failure to stderr in tests 8, 9, 10. 6. Replaced bogus "FAIL" with "SKIPPED" in test 0007 7. All "..." are prefixed and followed by a space.

Basic test to ensure that empty directories can be registered and that they in turn can serve as a base dir for other registrations. Add one test to the sysctl selftest module. It first registers an empty directory under "empty_add" and then uses that as a base to register another empty dir. The sysctl bash script then checks that "empty_add" is present and that there an empty directory within it.

Some devices have errata due to which they cannot report ETH_ZLEN (60) in the rx-min-frag-size. This was foreseen of course, and lldpad has logic that when we request it to advertise addFragSize 0, it will round it up to the lowest value that is _actually_ supported by the hardware.

2023-12-22tracing/selftests: Add ownership modification tests for eventfsSteven Rostedt (Google)1-0/+114
As there were bugs found with the ownership of eventfs dynamic file creation. Add a test to test it. It will remount tracefs with a different gid and check the ownership of the eventfs directory, as well as the system and event directories. It will also check the event file directories. It then does a chgrp on each of these as well to see if they all get updated as expected. Then it remounts the tracefs file system back to the original group and makes sure that all the updated files and directories were reset back to the original ownership. It does the same for instances that change the ownership of he instance directory. Note, because the uid is not reset by a remount, it is tested for every file by switching it to a new owner and then back again.

2023-12-22netfilter: ctnetlink: support filtering by zoneFelix Huettner3-1/+434
conntrack zones are heavily used by tools like openvswitch to run multiple virtual "routers" on a single machine. In this context each conntrack zone matches to a single router, thereby preventing overlapping IPs from becoming issues. In these systems it is common to operate on all conntrack entries of a given zone, e.g. to delete them when a router is deleted. Previously this required these tools to dump the full conntrack table and filter out the relevant entries in userspace potentially causing performance issues. To do this we reuse the existing CTA_ZONE attribute. This was previous parsed but not used during dump and flush requests. Now if CTA_ZONE is set we filter these operations based on the provided zone. However this means that users that previously passed CTA_ZONE will experience a difference in functionality. Alternatively CTA_FILTER could have been used for the same functionality. However it is not yet supported during flush requests and is only available when using AF_INET or AF_INET6.

2023-12-21tracing: Update subbuffer with kilobytes not page orderSteven Rostedt (Google)1-9/+9
Using page order for deciding what the size of the ring buffer sub buffers are is exposing a bit too much of the implementation. Although the sub buffers are only allocated in orders of pages, allow the user to specify the minimum size of each sub-buffer via kilobytes like they can with the buffer size itself. If the user specifies 3 via: echo 3 > buffer_subbuf_size_kb Then the sub-buffer size will round up to 4kb (on a 4kb page size system). If they specify: echo 6 > buffer_subbuf_size_kb The sub-buffer size will become 8kb. and so on.
