[PATCH bpf-next v1] selftests/bpf:Enhance bpf ability to detect ksym read error by libcap

by Lin Yikai

Ksym addr access is restricted by ``kptr_restrict``(/proc/sys/kernel/kptr_restrict). On some OS systems(like Android), ksym addr access is not accessed because ``kptr_restrict=2`. And it took me a long time to find the root case. -When ``kptr_restrict==0``, addr is accessed. # echo 0 > /proc/sys/kernel/kptr_restrict # cat /proc/kallsyms | grep bpf_link_fops ffffffd6bfd3fb60 d bpf_link_fops -When ``kptr_restrict==2``, addr is replaced by ZERO. # echo 2 > /proc/sys/kernel/kptr_restrict # cat /proc/kallsyms | grep bpf_link_fops 0000000000000000 d bpf_link_fops -When ``kptr_restrict==1``, addr is accessed for user having CAP_SYSLOG. So we should perform a check to remind users for these conditions before reading /proc/kallsyms.

[PATCH 0/2] unicode: kunit: refactor selftest to kunit tests

by Gabriela Bittencourt

Hey all, We are making these changes as part of a KUnit Hackathon at LKCamp [1]. This patch sets out to refactor fs/unicode/utf8-selftest.c to KUnit tests. The first commit is the refactoring itself from self test into KUnit, while the second one applies the naming style conventions. We appreciate any feedback and suggestions. :) (Resending patch series with the right lists on cc: kselftest and kunit-dev).

[PATCH v3 0/5] KVM: s390: selftests: Add regression tests for CPU subfunctions

by Hariharan Mari

This patch series introduces a set of regression tests for various s390x CPU subfunctions in KVM. The tests ensure that the KVM implementation accurately reflects the behavior of actual CPU instructions for these subfunctions. The series adds tests for a total of 15 instructions across five patches, covering a range of operations including sorting, compression, and various cryptographic functions. Each patch follows a consistent testing pattern: 1. Obtain the KVM_S390_VM_CPU_MACHINE_SUBFUNC attribute for the VM. 2. Execute the relevant asm instructions. 3. Compare KVM-reported results with direct instruction execution results. Testing has been performed on s390x hardware with KVM support. All tests pass successfully, verifying the correct implementation of these subfunctions in KVM. --- v2: * Fix facility_bit type from bool to int v3: * Global variable in the header is moved to facility.c file in selftests/kvm/lib/s390x/ * Fixed the line length * Fixed single line comments and multiline comments * Renamed the PLO macro * Removed the unnecessary type cast where Implicit type promotion applies --- Hariharan Mari (5): KVM: s390: selftests: Add regression tests for SORTL and DFLTCC CPU subfunctions KVM: s390: selftests: Add regression tests for PRNO, KDSA and KMA crypto subfunctions KVM: s390: selftests: Add regression tests for KMCTR, KMF, KMO and PCC crypto subfunctions KVM: s390: selftests: Add regression tests for KMAC, KMC, KM, KIMD and KLMD crypto subfunctions KVM: s390: selftests: Add regression tests for PLO subfunctions tools/testing/selftests/kvm/Makefile | 2 + .../selftests/kvm/include/s390x/facility.h | 50 +++ .../selftests/kvm/lib/s390x/facility.c | 14 + .../kvm/s390x/cpumodel_subfuncs_test.c | 286 ++++++++++++++++++ 4 files changed, 352 insertions(+) create mode 100644 tools/testing/selftests/kvm/include/s390x/facility.h create mode 100644 tools/testing/selftests/kvm/lib/s390x/facility.c create mode 100644 tools/testing/selftests/kvm/s390x/cpumodel_subfuncs_test.c -- 2.45.2

[PATCH RFC v3 0/9] tun: Introduce virtio-net hashing feature

by Akihiko Odaki

virtio-net have two usage of hashes: one is RSS and another is hash reporting. Conventionally the hash calculation was done by the VMM. However, computing the hash after the queue was chosen defeats the purpose of RSS. Another approach is to use eBPF steering program. This approach has another downside: it cannot report the calculated hash due to the restrictive nature of eBPF. Introduce the code to compute hashes to the kernel in order to overcome thse challenges. An alternative solution is to extend the eBPF steering program so that it will be able to report to the userspace, but it is based on context rewrites, which is in feature freeze. We can adopt kfuncs, but they will not be UAPIs. We opt to ioctl to align with other relevant UAPIs (KVM and vhost_net). QEMU patched to use this new feature is available at: https://github.com/daynix/qemu/tree/akihikodaki/rss2 The QEMU patches will soon be submitted to the upstream as RFC too. This work will be presented at LPC 2024: https://lpc.events/event/18/contributions/1963/ V1 -> V2: Changed to introduce a new BPF program type.

[PATCH v6.11 v5.15 v5.4 v4.19 1/1] selftests: breakpoints: use remaining time to check if suspend succeed

by Yifei Liu

We recently notice that the step_after_suspend_test would fail on our plenty devices. The test believesit failed to enter suspend state with $ sudo ./step_after_suspend_test TAP version 13 Bail out! Failed to enter Suspend state However, in the kernel message, I indeed see the system get suspended and then wake up later. [611172.033108] PM: suspend entry (s2idle) [611172.044940] Filesystems sync: 0.006 seconds [611172.052254] Freezing user space processes [611172.059319] Freezing user space processes completed (elapsed 0.001 seconds) [611172.067920] OOM killer disabled.

[611203.140637] Restarting tasks ... [611203.141135] usb 1-8.1: USB disconnect, device number 7 [611203.141755] done. [611203.155268] random: crng reseeded on system resumption [611203.162059] PM: suspend exit After investigation, I notice that for the code block if (write(power_state_fd, "mem", strlen("mem")) != strlen("mem")) ksft_exit_fail_msg("Failed to enter Suspend state\n"); The write will return -1 and errno is set to 16 (device busy). It should be caused by the write function is not successfully returned before the system suspend and the return value get messed when waking up. As a result, It may be better to check the time passed of those few instructions to determine whether the suspend is executed correctly for it is pretty hard to execute those few lines for 5 seconds. The timer to wake up the system is set to expired after 5 seconds and no-rearm. If the timer remaining time is 0 second and 0 nano secomd, it means the timer expired and wake the system up. Otherwise, the system could be considered to enter the suspend state failed if there is any remaining time.
