2025-04-15kunit: tool: Implement listing of available architecturesThomas Weißschuh
To implement custom scripting around kunit.py it is useful to get a list of available architectures. While it is possible to manually inspect tools/testing/kunit/qemu_configs/, this is annoying to implement and introduces a dependency on a kunit.py implementation detail. Introduce 'kunit.py run --arch help' which lists all known architectures in an easy to parse list. This is equivalent on how QEMU implements listing of possible argument values.

2025-04-15selftests: mptcp: use IPPROTO_MPTCP for getaddrinfozhenwei pi
mptcp_connect.c is a startup tutorial of MPTCP programming, however there is a lack of ai_protocol(IPPROTO_MPTCP) usage. Add comment for getaddrinfo MPTCP support. This patch first uses IPPROTO_MPTCP to get addrinfo, and if glibc version is too old, it falls back to using IPPROTO_TCP.

It's strange that 'nlh' variable is set to NULL in get_mptcpinfo() and then this NULL pointer is passed to recv_nlmsg(). In fact, this variable should be defined in recv_nlmsg(), not get_mptcpinfo().

The parent commit adds this new counter, incremented when receiving a connection request, if the PM didn't allow the creation of new subflows. Most of the time, it is then kept at 0, except when the PM limits cause the receiver side to reject new MPJoin connections. This is the case in the following tests: - single subflow, limited by server - multiple subflows, limited by server - subflows limited by server w cookies - userspace pm type rejects join - userspace pm type prevents mp_prio Simply set join_syn_rej=1 when checking the MPJoin counters for these tests.

2025-04-14kunit: qemu_configs: SH: Respect kunit cmdlineThomas Weißschuh
The default SH kunit configuration sets CONFIG_CMDLINE_OVERWRITE which completely disregards the cmdline passed from the bootloader/QEMU in favor of the builtin CONFIG_CMDLINE. However the kunit tool needs to pass arguments to the in-kernel kunit core, for filters and other runtime parameters. Enable CONFIG_CMDLINE_EXTEND instead, so kunit arguments are respected.

git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing fixes from Steven Rostedt: - Hide get_vm_area() from MMUless builds The function get_vm_area() is not defined when CONFIG_MMU is not defined. Hide that function within #ifdef CONFIG_MMU. - Fix output of synthetic events when they have dynamic strings The print fmt of the synthetic event's format file use to have "%.*s" for dynamic size strings even though the user space exported arguments had only __get_str() macro that provided just a nul terminated string. This was fixed so that user space could parse this properly. But the reason that it had "%.*s" was because internally it provided the maximum size of the string as one of the arguments. The fix that replaced "%.*s" with "%s" caused the trace output (when the kernel reads the event) to write "(efault)" as it would now read the length of the string as "%s". As the string provided is always nul terminated, there's no reason for the internal code to use "%.*s" anyway. Just remove the length argument to match the "%s" that is now in the format. - Fix the ftrace subops hash logic of the manager ops hash The function_graph uses the ftrace subops code. The subops code is a way to have a single ftrace_ops registered with ftrace to determine what functions will call the ftrace_ops callback. More than one user of function graph can register a ftrace_ops with it. The function graph infrastructure will then add this ftrace_ops as a subops with the main ftrace_ops it registers with ftrace. This is because the functions will always call the function graph callback which in turn calls the subops ftrace_ops callbacks. The main ftrace_ops must add a callback to all the functions that the subops want a callback from. When a subops is registered, it will update the main ftrace_ops hash to include the functions it wants. This is the logic that was broken. The ftrace_ops hash has a "filter_hash" and a "notrace_hash" where all the functions in the filter_hash but not in the notrace_hash are attached by ftrace. The original logic would have the main ftrace_ops filter_hash be a union of all the subops filter_hashes and the main notrace_hash would be a intersect of all the subops filter hashes. But this was incorrect because the notrace hash depends on the filter_hash it is associated to and not the union of all filter_hashes. Instead, when a subops is added, just include all the functions of the subops hash that are in its filter_hash but not in its notrace_hash. The main subops hash should not use its notrace hash, unless all of its subops hashes have an empty filter_hash (which means to attach to all functions), and then, and only then, the main ftrace_ops notrace hash can be the intersect of all the subops hashes. This not only fixes the bug, but also simplifies the code. - Add a selftest to better test the subops filtering Add a selftest that would catch the bug fixed by the above change. - Fix extra newline printed in function tracing with retval The function parameter code changed the output logic slightly and called print_graph_retval() and also printed a newline. The print_graph_retval() also prints a newline which caused blank lines to be printed in the function graph tracer when retval was added. This caused one of the selftests to fail if retvals were enabled. Instead remove the new line output from print_graph_retval() and have the callers always print the new line so that it doesn't have to do special logic if it calls print_graph_retval() or not. - Fix out-of-bound memory access in the runtime verifier When rv_is_container_monitor() is called on the last entry on the link list it references the next entry, which is the list head and causes an out-of-bound memory access. * tag 'trace-v6.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: rv: Fix out-of-bound memory access in rv_is_container_monitor() ftrace: Do not have print_graph_retval() add a newline tracing/selftest: Add test to better test subops filtering of function graph ftrace: Fix accounting of subop hashes ftrace: Properly merge notrace hashes tracing: Do not add length to print format in synthetic events tracing: Hide get_vm_area() from MMUless builds

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.

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 _.

2025-04-10selftests/xsk: Add tail adjustment tests and support checkTushar Vyavahare
Introduce tail adjustment functionality in xskxceiver using bpf_xdp_adjust_tail(). Add `xsk_xdp_adjust_tail` to modify packet sizes and drop unmodified packets. Implement `is_adjust_tail_supported` to check helper availability. Develop packet resizing tests, including shrinking and growing scenarios, with functions for both single-buffer and multi-buffer cases. Update the test framework to handle various scenarios and adjust MTU settings. These changes enhance the testing of packet tail adjustments, improving AF_XDP framework reliability.

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.

2025-04-09selftest/bpf/benchs: Add benchmark for sockmap usageJiayuan Chen
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. This will enable better support for various socket types.
