2024-10-10selftests/bpf: Fix cross-compiling urandom_readTony Ambardar
Linking of urandom_read and liburandom_read.so prefers LLVM's 'ld.lld' but falls back to using 'ld' if unsupported. However, this fallback discards any existing makefile macro for LD and can break cross-compilation. Fix by changing the fallback to use the target linker $(LD), passed via '-fuse-ld=' using an absolute path rather than a linker "flavour".

2024-10-10selftests/bpf: check program redirect in xdp_cpumap_attachAlexis Lothoré (eBPF Foundation)
xdp_cpumap_attach, in its current form, only checks that an xdp cpumap program can be executed, but not that it performs correctly the cpu redirect as configured by userspace (bpf_prog_test_run_opts will return success even if the redirect program returns an error) Add a check to ensure that the program performs the configured redirect as well. The check is based on a global variable incremented by a chained program executed only if the redirect program properly executes.

xdp_redir_prog currently redirects packets based on the entry at index 1 in cpu_map, but the corresponding test only manipulates the entry at index 0. This does not really affect the test in its current form since the program is detached before having the opportunity to execute, but it needs to be fixed before being able improve the corresponding test (ie, not only test attach/detach but also the redirect feature) Fix this XDP program by making it redirect packets based on entry 0 in cpu_map instead of entry 1.

2024-10-09selftests/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.

2024-10-09selftests: 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.

2024-10-08selftests: mlxsw: sch_red_core: Lower TBF ratePetr Machata
The RED test uses a pair of TBF shapers. The first to get predictably-sized stream of traffic, and second to get a 100% saturated chokepoint. To this chokepoint it injects individual packets. Because the chokepoint is saturated, these additional packets go straight to the backlog. This allows the test to check RED behavior across various queue sizes. The shapers are rated at 1Gbps, for historical reasons (before mlxsw supported TBF offload, the test used port speed to create the chokepoints). Machines with a low-power CPU may have trouble consistently generating 1Gbps of traffic, and the test then spuriously fails. Instead, drop the rate to 200Mbps (Spectrum has a guaranteed shaper rate granularity of 200Mbps, so anything lower is not guaranteed to work well). Because that means fewer packets will be mirrored in the ECN-mark test, adjust the passing condition accordingly.

2024-10-08selftests: mlxsw: sch_red_core: Send more packets for drop testsPetr Machata
This test works by injecting into a port with a maxed-out queue a couple packets and checks if a corresponding number of packets were dropped. This has worked well on Spectrum<4, but on Spectrum-4 it has been noisy. This is in line with the observation that on Spectrum-4, queue size tends to fluctuate more. A handful of packets could then still be accepted to the queue even though it was nominally full just recently. In order to accommodate this behavior, send many more packets. The buffer can fit N extra packets, but not N% packets. This therefore allows us to set wider absolute margins, while actually narrowing them relatively.

2024-10-08selftests: mlxsw: sch_red_core: Sleep before querying queue depthPetr Machata
The qdisc stats are taken from the port's periodic HW stats, which are updated once a second. We try to accommodate the latency by using busywait in build_backlog(). The issue in that seems to be that when do_mark_test() builds the backlog, it makes the decision whether to send more packets based on the first instance of the queue depth stat exceeding the current value, when in fact more traffic is on the way and the queue depth would increase further. This leads to failures in TC 1 of mark-mirror test, where we see the following failure: TEST: TC 0: marked packets mirror'd [ OK ] TEST: TC 1: marked packets mirror'd [FAIL] Spurious packets (1680 -> 2290) observed without buffer pressure Fix by waiting for the full second before reading the queue depth for the first time, to make sure it reflects all in-flight traffic.

2024-10-08selftests: mlxsw: sch_red_core: Increase backlog size tolerancePetr Machata
Backlog fluctuates on Spectrum-4 much more than on <4. In practice we can sample queue depth values going from about -12% to about +7% of the configured RED limit. The test which checks the queue size has a limit of +-10%, and as a result often fails. We attempted to fix the issue by busywaiting for several seconds hoping to get within the bounds, but that still proved to be too noisy (or the wait time would be impractically long). Unfortunately we have to bump the value tolerance from 10% to 15%, which in this patch do.

scx_qmap and other schedulers in the SCX repo are using SCX_ENQ_WAKEUP to tell whether ops.select_cpu() was called. This is incorrect as ops.select_cpu() can be skipped in the wakeup path and leads to e.g. incorrectly skipping direct dispatch for tasks that are bound to a single CPU. sched core has been updated to specify ENQUEUE_RQ_SELECTED if ->select_task_rq() was called. Map it to SCX_ENQ_CPU_SELECTED and update scx_qmap to test it instead of SCX_ENQ_WAKEUP.

2024-10-04net: add IFLA_MAX_PACING_OFFLOAD_HORIZON device attributeEric Dumazet
Some network devices have the ability to offload EDT (Earliest Departure Time) which is the model used for TCP pacing and FQ packet scheduler. Some of them implement the timing wheel mechanism described in https://saeed.github.io/files/carousel-sigcomm17.pdf with an associated 'timing wheel horizon'. This patch adds dev->max_pacing_offload_horizon expressing this timing wheel horizon in nsec units. This is a read-only attribute. Unless a driver sets it, dev->max_pacing_offload_horizon is zero. v2: addressed Jakub feedback ( https://lore.kernel.org/netdev/20240930152304.472767-2-edumazet@google.com/T/#mf6294d714c41cc459962154cc2580ce3c9693663 ) v3: added yaml doc (also per Jakub feedback) Signed-off-by: Eric Dumazet <edumazet@google.com> Reviewed-by: Willem de Bruijn <willemb@google.com> Link: https://patch.msgid.link/20241003121219.2396589-2-edumazet@google.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>

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>

git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing fixes from Steven Rostedt: - Fix tp_printk command line option crashing the kernel With the code that can handle a buffer from a previous boot, the trace_check_vprintf() needed access to the delta of the address space used by the old buffer and the current buffer. 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. As timerlat has callbacks from hotplug code to start kthreads when CPUs come online. There are also locking issues with grabbing the cpu_read_lock() and the locks within timerlat. * tag 'trace-v6.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: tracing/hwlat: Fix a race during cpuhp processing tracing/timerlat: Fix a race during cpuhp processing tracing/timerlat: Drop interface_lock in stop_kthread() tracing/timerlat: Fix duplicated kthread creation due to CPU online/offline x86/ftrace: Include <asm/ptrace.h> rtla: Fix the help text in osnoise and timerlat top tools tools/rtla: Fix installation from out-of-tree build tracing: Fix trace_check_vprintf() when tp_printk is used
