2025-05-16rcutorture: Remove MAXSMP and CPUMASK_OFFSTACK from TREE01Paul E. McKenney
Back in the day, rcutorture was about the only thing that tested off-stack CPU masks, but now any arm64 system with more than 256 CPUs tests it full time. In fact, it is necessary to hack the kernel to prevent such a system from testing off-stack CPU masks. This means that there is no longer much point in rcutorture going out of its way to test this. And given the differences in how CPUMASK_OFFSTACK is enabled in x86 and arm64, rcutorture would need to go out of its way. This commit therefore removes CONFIG_CPUMASK_OFFSTACK=y (and the CONFIG_MAXSMP=y required to enable it on x86) from TREE01. Signed-off-by: Paul E.

2025-05-16rcutorture: Reduce TREE01 CPU overcommitPaul E. McKenney
The TREE01.boot nr_cpus kernel boot parameter has been set to 43 for more than seven years, but it can cause RCU CPU stall warnings on arm64, most of the time involving the stop-machine subsystem. This should not be too surprising, given that this causes 43 vCPUs to spin with interrupts disabled when there are only eight physical CPUs. The point of this CPU overcommit is to test the ability of expedited RCU grace period initialization to handle races with incoming CPUs that have never previously been online. But limiting to 17 CPUs instead of 43 allows time for this code to be exercised, and eliminates (or at least greatly reduces) the incidence of RCU CPU stall warnings on arm64. So this commit therefore sets nr_cpus=17 in TREE01.boot. Signed-off-by: Paul E. McKenney <paulmck@kernel.org> Signed-off-by: Joel Fernandes <joelagnelf@nvidia.com>

2025-05-16torture: Add testing of RCU's Rust bindings to torture.shPaul E. McKenney
This commit adds a --do-rcu-rust parameter to torture.sh, which invokes a rust_doctests_kernel kunit run. Note that kunit wants a clean source tree, so this runs "make mrproper", which might come as a surprise to some users. Should there be a --mrproper parameter to torture.sh to make the user explicitly ask for it?

2025-05-16torture: Add --do-{,no-}normal to torture.shPaul E. McKenney
Right now, torture.sh runs normal runs unconditionally, which can be slow and thus annoying when you only want to test --kcsan or --kasan runs. This commit therefore adds a --do-normal argument so that "--kcsan --do-no-kasan --do-no-normal" runs only KCSAN runs. Note that specifying "--do-no-kasan --do-no-kcsan --do-no-normal" gets normal runs, so you should not try to use this as a synonym for --do-none. Signed-off-by: Paul E.

2025-05-16xdrgen: Fix code generated for counted arraysChuck Lever
When an XDR counted array has a maximum element count, xdrgen adds a bounds check to the encoder or decoder for that type. But in cases where the .x provides no maximum element count, such as struct notify4 { /* composed from notify_type4 or notify_deviceid_type4 */ bitmap4 notify_mask; notifylist4 notify_vals; }; struct CB_NOTIFY4args { stateid4 cna_stateid; nfs_fh4 cna_fh; notify4 cna_changes<>; }; xdrgen is supposed to omit that bounds check. Some of the Jinja2 templates handle that correctly, but a few are incorrect and leave the bounds check in place with a maximum of zero, which causes encoding/decoding of that type to fail unconditionally.

2025-05-16kselftest/arm64: Set default OUTPUT path when undefinedtanze
When running 'make' in tools/testing/selftests/arm64/ without explicitly setting the OUTPUT variable, the build system will creates test directories (e.g., /bti) in the root filesystem due to OUTPUT defaulting to an empty string.

2025-05-13vsock/test: Fix occasional failure in SIOCOUTQ testsKonstantin Shkolnyy
These tests: "SOCK_STREAM ioctl(SIOCOUTQ) 0 unsent bytes" "SOCK_SEQPACKET ioctl(SIOCOUTQ) 0 unsent bytes" output: "Unexpected 'SIOCOUTQ' value, expected 0, got 64 (CLIENT)". They test that the SIOCOUTQ ioctl reports 0 unsent bytes after the data have been received by the other side. However, sometimes there is a delay in updating this "unsent bytes" counter, and the test fails even though the counter properly goes to 0 several milliseconds later. The delay occurs in the kernel because the used buffer notification callback virtio_vsock_tx_done(), called upon receipt of the data by the other side, doesn't update the counter itself. It delegates that to a kernel thread (via vsock->tx_work). Sometimes that thread is delayed more than the test expects. Change the test to poll SIOCOUTQ until it returns 0 or a timeout occurs.

2025-05-13tools: ynl-gen: Allow multi-attr without nested-attributes againLukas Wunner
Since commit ce6cb8113c84 ("tools: ynl-gen: individually free previous values on double set"), specifying the "multi-attr" property raises an error unless the "nested-attributes" property is specified as well: File "tools/net/ynl/./pyynl/ynl_gen_c.py", line 1147, in _load_nested_sets child = self.pure_nested_structs.get(nested) ^^^^^^ UnboundLocalError: cannot access local variable 'nested' where it is not associated with a value This appears to be a bug since there are existing specs which omit "nested-attributes" on "multi-attr" attributes. Also, according to Documentation/userspace-api/netlink/specs.rst, multi-attr "is the recommended way of implementing arrays (no extra nesting)", suggesting that nesting should even be avoided in favor of multi-attr.

2025-05-13tools: ynl-gen: support struct for binary attributesJakub Kicinski
Support using a struct pointer for binary attrs. Len field is maintained because the structs may grow with newer kernel versions. Or, which matters more, be shorter if the binary is built against newer uAPI than kernel against which it's executed. Since we are storing a pointer to a struct type - always allocate at least the amount of memory needed by the struct per current uAPI headers (unused mem is zeroed). Technically users should check the length field but per modern ASAN checks storing a short object under a pointer seems like a bad idea.

2025-05-12selftests/fs/mount-notify: add a test variant running inside usernsAmir Goldstein
unshare userns in addition to mntns and verify that: 1. watching tmpfs mounted inside userns is allowed with any mark type 2. watching orig root with filesystem mark type is not allowed 3. watching mntns of orig userns is not allowed 4. watching mntns in userns where fanotify_init was called is allowed mount events are only tested with the last case of mntns mark.
