2025-04-11selftests: mincore: fix tmpfs mincore test failureBaolin Wang
When running mincore test cases, I encountered the following failures: " mincore_selftest.c:359:check_tmpfs_mmap:Expected ra_pages (511) == 0 (0) mincore_selftest.c:360:check_tmpfs_mmap:Read-ahead pages found in memory check_tmpfs_mmap: Test terminated by assertion FAIL global.check_tmpfs_mmap not ok 5 global.check_tmpfs_mmap FAILED: 4 / 5 tests passed " The reason for the test case failure is that my system automatically enabled tmpfs large folio allocation by adding the 'transparent_hugepage_tmpfs=always' cmdline. However, the test case still expects the tmpfs mounted on /dev/shm to allocate small folios, which leads to assertion failures when verifying readahead pages. As discussed with David, there's no reason to continue checking the readahead logic for tmpfs. Drop it to fix this issue.

2025-04-11selftests/mm: generate a temporary mountpoint for cgroup filesystemMark Brown
Currently if the filesystem for the cgroups version it wants to use is not mounted charge_reserved_hugetlb.sh and hugetlb_reparenting_test.sh tests will attempt to mount it on the hard coded path /dev/cgroup/memory, deleting that directory when the test finishes. This will fail if there is not a preexisting directory at that path, and since the directory is deleted subsequent runs of the test will fail. Instead of relying on this hard coded directory name use mktemp to generate a temporary directory to use as a mountpoint, fixing both the assumption and the disruption caused by deleting a preexisting directory. This means that if the relevant cgroup filesystem is not already mounted then we rely on having coreutils (which provides mktemp) installed. I suspect that many current users are relying on having things automounted by default, and given that the script relies on bash it's probably not an unreasonable requirement.

A bug was discovered that showed the accounting of the subops of the ftrace_ops filtering was incorrect. Add a new test to better test the filtering. This test creates two instances, where it will add various filters to both the set_ftrace_filter and the set_ftrace_notrace files and enable function_graph. Then it looks into the enabled_functions file to make sure that the filters are behaving correctly.

2025-04-10netlink: specs: rename rtnetlink specs in accordance with family nameJakub Kicinski
The rtnetlink family names are set to rt-$name within the YAML but the files are called rt_$name. C codegen assumes that the generated file name will match the family. The use of dashes is in line with our general expectation that name properties in the spec use dashes not underscores (even tho, as Donald points out most genl families use underscores in the name). We have 3 un-ideal options to choose from: - accept the slight inconsistency with old families using _, or - accept the slight annoyance with all languages having to do s/-/_/ when looking up family ID, or - accept the inconsistency with all name properties in new YAML spec being separated with - and just the family name always using _. Pick option 1 and rename the rtnl spec files.

2025-04-09selftests/bpf: Add test case for atomic update of fd htabHou Tao
Add a test case to verify the atomic update of existing elements in the htab of maps. The test proceeds in three steps: 1) fill the outer map with keys in the range [0, 8] For each inner array map, the value of its first element is set as the key used to lookup the inner map. 2) create 16 threads to lookup these keys concurrently Each lookup thread first lookups the inner map, then it checks whether the first value of the inner array map is the same as the key used to lookup the inner map. 3) create 8 threads to overwrite these keys concurrently Each update thread first creates an inner array, it sets the first value of the array to the key used to update the outer map, then it uses the key and the inner map to update the outer map. Without atomic update support, the lookup operation may return -ENOENT during the lookup of outer map, or return -EINVAL during the comparison of the first value in the inner map and the key used for inner map, and the test will fail. After the atomic update change, both the lookup and the comparison will succeed. Given that the update of outer map is slow, the test case sets the loop number for each thread as 5 to reduce the total running time. However, the loop number could also be adjusted through FD_HTAB_LOOP_NR environment variable.

Add TCP+sockmap-based benchmark. Since sockmap's own update and delete operations are generally less critical, the performance of the fast forwarding framework built upon it is the key aspect. Also with cgset/cgexec, we can observe the behavior of sockmap under memory pressure. The benchmark can be run with: ''' ./bench sockmap -c 2 -p 1 -a --rx-verdict-ingress ''' In the future, we plan to move socket_helpers.h out of the prog_tests directory to make it accessible for the benchmark.

2025-04-08selftests/mincore: Allow read-ahead pages to reach the end of the fileQiuxu Zhuo
When running the mincore_selftest on a system with an XFS file system, it failed the "check_file_mmap" test case due to the read-ahead pages reaching the end of the file. The failure log is as below: RUN global.check_file_mmap ... mincore_selftest.c:264:check_file_mmap:Expected i (1024) < vec_size (1024) mincore_selftest.c:265:check_file_mmap:Read-ahead pages reached the end of the file check_file_mmap: Test failed FAIL global.check_file_mmap This is because the read-ahead window size of the XFS file system on this machine is 4 MB, which is larger than the size from the #PF address to the end of the file. As a result, all the pages for this file are populated. blockdev --getra /dev/nvme0n1p5 8192 blockdev --getbsz /dev/nvme0n1p5 512 This issue can be fixed by extending the current FILE_SIZE 4MB to a larger number, but it will still fail if the read-ahead window size of the file system is larger enough. Additionally, in the real world, read-ahead pages reaching the end of the file can happen and is an expected behavior. Therefore, allowing read-ahead pages to reach the end of the file is a better choice for the "check_file_mmap" test case.
