46 hoursmaple_tree: add regression test for spanning store bugLorenzo Stoakes
Add a regression test to assert that, when performing a spanning store which consumes the entirety of the rightmost right leaf node does not result in maple tree corruption when doing so. This achieves this by building a test tree of 3 levels and establishing a store which ultimately results in a spanned store of this nature.

2 daysmaple_tree: check for MA_STATE_BULK on setting wr_rebalanceSidhartha Kumar
It is possible for a bulk operation (MA_STATE_BULK is set) to enter the new_end < mt_min_slots[type] case and set wr_rebalance as a store type. This is incorrect as bulk stores do not rebalance per write, but rather after the all of the writes are done through the mas_bulk_rebalance() path. Therefore, add a check to make sure MA_STATE_BULK is not set before we return wr_rebalance as the store type. Also add a test to make sure wr_rebalance is never the store type when doing bulk operations via mas_expected_entries() This is a hotfix for this rc however it has no userspace effects as there are no users of the bulk insertion mode.

2 daysselftests/mm: replace atomic_bool with pthread_barrier_tEdward Liaw
Patch series "selftests/mm: fix deadlock after pthread_create". On Android arm, pthread_create followed by a fork caused a deadlock in the case where the fork required work to be completed by the created thread. Update the synchronization primitive to use pthread_barrier instead of atomic_bool. Apply the same fix to the wp-fork-with-event test. This patch (of 2): Swap synchronization primitive with pthread_barrier, so that stdatomic.h does not need to be included. The synchronization is needed on Android ARM64; we see a deadlock with pthread_create when the parent thread races forward before the child has a chance to start doing work.

10 daysselftests/mm: fix incorrect buffer->mirror size in hmm2 double_map testDonet Tom
The hmm2 double_map test was failing due to an incorrect buffer->mirror size. The buffer->mirror size was 6, while buffer->ptr size was 6 * PAGE_SIZE. The test failed because the kernel's copy_to_user function was attempting to copy a 6 * PAGE_SIZE buffer to buffer->mirror. Since the size of buffer->mirror was incorrect, copy_to_user failed. This patch corrects the buffer->mirror size to 6 * PAGE_SIZE.

10 daysselftests: sched_ext: Add sched_ext as proper selftest targetBjörn Töpel
The sched_ext selftests is missing proper cross-compilation support, a proper target entry, and out-of-tree build support. When building the kselftest suite, e.g.: make ARCH=riscv CROSS_COMPILE=riscv64-linux-gnu- \ TARGETS=sched_ext SKIP_TARGETS="" O=/output/foo \ -C tools/testing/selftests install or: make ARCH=arm64 LLVM=1 TARGETS=sched_ext SKIP_TARGETS="" \ O=/output/foo -C tools/testing/selftests install The expectation is that the sched_ext is included, cross-built, the correct toolchain is picked up, and placed into /output/foo. In contrast to the BPF selftests, the sched_ext suite does not use bpftool at test run-time, so it is sufficient to build bpftool for the build host only. Add ARCH, CROSS_COMPILE, OUTPUT, and TARGETS support to the sched_ext selftest. Also, remove some variables that were unused by the Makefile.

2024-10-04selftests: net: no_forwarding: fix VID for $swp2 in one_bridge_two_pvids() testKacper Ludwinski
Currently, the second bridge command overwrites the first one. Fix this by adding this VID to the interface behind $swp2. The one_bridge_two_pvids() test intends to check that there is no leakage of traffic between bridge ports which have a single VLAN - the PVID VLAN. Because of a typo, port $swp1 is configured with a PVID twice (second command overwrites first), and $swp2 isn't configured at all (and since the bridge vlan_default_pvid property is set to 0, this port will not have a PVID at all, so it will drop all untagged and priority-tagged traffic). So, instead of testing the configuration that was intended, we are testing a different one, where one port has PVID 2 and the other has no PVID. This incorrect version of the test should also pass, but is ineffective for its purpose, so fix the typo. This typo has an impact on results of the test, potentially leading to wrong conclusions regarding the functionality of a network device. The tests results: TEST: Switch ports in VLAN-aware bridge with different PVIDs: Unicast non-IP untagged [ OK ] Multicast non-IP untagged [ OK ] Broadcast non-IP untagged [ OK ] Unicast IPv4 untagged [ OK ] Multicast IPv4 untagged [ OK ] Unicast IPv6 untagged [ OK ] Multicast IPv6 untagged [ OK ] Unicast non-IP VID 1 [ OK ] Multicast non-IP VID 1 [ OK ] Broadcast non-IP VID 1 [ OK ] Unicast IPv4 VID 1 [ OK ] Multicast IPv4 VID 1 [ OK ] Unicast IPv6 VID 1 [ OK ] Multicast IPv6 VID 1 [ OK ] Unicast non-IP VID 4094 [ OK ] Multicast non-IP VID 4094 [ OK ] Broadcast non-IP VID 4094 [ OK ] Unicast IPv4 VID 4094 [ OK ] Multicast IPv4 VID 4094 [ OK ] Unicast IPv6 VID 4094 [ OK ] Multicast IPv6 VID 4094 [ OK ] Fixes: 476a4f05d9b8 ("selftests: forwarding: add a no_forwarding.sh test") Reviewed-by: Hangbin Liu <liuhangbin@gmail.com> Reviewed-by: Shuah Khan <skhan@linuxfoundation.org> Signed-off-by: Kacper Ludwinski <kac.ludwinski@icloud.com> Link: https://patch.msgid.link/20241002051016.849-1-kac.ludwinski@icloud.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>

To do so, the trace_array (tr) parameter was used. But when tp_printk is enabled on the kernel command line, no trace buffer is used and the trace event is sent directly to printk(). That meant the tr field of the iterator descriptor was NULL, and since tp_printk still uses trace_check_vprintf() it caused a NULL dereference. - Add ptrace.h include to x86 ftrace file for completeness - Fix rtla installation when done with out-of-tree build - Fix the help messages in rtla that were incorrect - Several fixes to fix races with the timerlat and hwlat code Several locking issues were discovered with the coordination between timerlat kthread creation and hotplug.
