[PATCH] kunit: tool: add test counts to JSON output

by Rae Moar

Add the test counts to the JSON output from kunit.py. For example: ... "git_branch": "kselftest", "misc": { "tests": 2, "passed": 1. "failed": 1, "crashed": 0, "skipped": 0, "errors": 0, } ... To output the JSON using the following command: ./tools/testing/kunit/kunit.py run example --json This has been requested by KUnit users. The counts are in a "misc" field because the JSON output needs to be compliant with the KCIDB submission guide. There are no counts fields but there is a "misc" field in the guide.

[PATCH v12 0/5] KVM: selftests: Add LoongArch support

by Bibo Mao

This patchset adds KVM selftests for LoongArch system, currently only some common test cases are supported and pass to run. These test cases are listed as following: coalesced_io_test demand_paging_test dirty_log_perf_test dirty_log_test guest_print_test hardware_disable_test kvm_binary_stats_test kvm_create_max_vcpus kvm_page_table_test memslot_modification_stress_test memslot_perf_test set_memory_region_test --- Changes in v12: 1. Replace vcpu_set_reg() with __vcpu_set_reg() in loongarch_set_csr() 2. Remove duplicated test case including in Makefile.kvm 3. Fix one issue reported by checkpatch Changes in v11: 1. Fix a typo issue in notes of patch 2, it is kvm_util_arch.h rather than kvm_util_base.h Changes in v10: 1. Add PS_64K and remove PS_8K in file include/loongarch/processor.h 2. Fix a typo issue in file lib/loongarch/processor.c 3. Update file MAINTAINERS about LoongArch KVM selftests Changes in v9: 1. Add vm mode VM_MODE_P47V47_16K, LoongArch VM uses this mode by default, rather than VM_MODE_P36V47_16K. 2. Refresh some spelling issues in changelog. Changes in v8: 1. Porting patch based on the latest version. 2. For macro PC_OFFSET_EXREGS, offsetof() method is used for C header file, still hardcoded definition for assemble language. Changes in v7: 1. Refine code to add LoongArch support in test case set_memory_region_test. Changes in v6: 1. Refresh the patch based on latest kernel 6.8-rc1, add LoongArch support about testcase set_memory_region_test. 2. Add hardware_disable_test test case. 3. Drop modification about macro DEFAULT_GUEST_TEST_MEM, it is problem of LoongArch binutils, this issue is raised to LoongArch binutils owners. Changes in v5: 1. In LoongArch kvm self tests, the DEFAULT_GUEST_TEST_MEM could be 0x130000000, it is different from the default value in memstress.h. So we Move the definition of DEFAULT_GUEST_TEST_MEM into LoongArch ucall.h, and add 'ifndef' condition for DEFAULT_GUEST_TEST_MEM in memstress.h. Changes in v4: 1. Remove the based-on flag, as the LoongArch KVM patch series have been accepted by Linux kernel, so this can be applied directly in kernel. Changes in v3: 1. Improve implementation of LoongArch VM page walk. 2. Add exception handler for LoongArch. 3. Add dirty_log_test, dirty_log_perf_test, guest_print_test test cases for LoongArch. 4.

Change the DEFAULT_GUEST_TEST_MEM base addr for LoongArch. Changes in v2: 1. We should use ".balign 4096" to align the assemble code with 4K in exception.S instead of "align 12". 2. LoongArch only supports 3 or 4 levels page tables, so we remove the hanlders for 2-levels page table. 3. Remove the DEFAULT_LOONGARCH_GUEST_STACK_VADDR_MIN and use the common DEFAULT_GUEST_STACK_VADDR_MIN to allocate stack memory in guest. 4. Reorganize the test cases supported by LoongArch. 5. Fix some code comments. 6.

[PATCH bpf-next v2 00/11] bpf: Mitigate Spectre v1 using barriers

by Luis Gerhorst

This improves the expressiveness of unprivileged BPF by inserting speculation barriers instead of rejecting the programs. The approach was previously presented at LPC'24 [1] and RAID'24 [2]. To mitigate the Spectre v1 (PHT) vulnerability, the kernel rejects potentially-dangerous unprivileged BPF programs as of commit 9183671af6db ("bpf: Fix leakage under speculation on mispredicted branches"). In [2], we have analyzed 364 object files from open source projects (Linux Samples and Selftests, BCC, Loxilb, Cilium, libbpf Examples, Parca, and Prevail) and found that this affects 31% to 54% of programs. To resolve this in the majority of cases this patchset adds a fall-back for mitigating Spectre v1 using speculation barriers. The kernel still optimistically attempts to verify all speculative paths but uses speculation barriers against v1 when unsafe behavior is detected. This allows for more programs to be accepted without disabling the BPF Spectre mitigations (e.g., by setting cpu_mitigations_off()). For this, it relies on the fact that speculation barriers prevent all later instructions if the speculation was not correct: * On x86_64, lfence acts as full speculation barrier, not only as a load fence [3]: An LFENCE instruction or a serializing instruction will ensure that no later instructions execute, even speculatively, until all prior instructions complete locally. [...] Inserting an LFENCE instruction after a bounds check prevents later operations from executing before the bound check completes. This was experimentally confirmed in [4]. * ARM's SB speculation barrier instruction also affects "any instruction that appears later in the program order than the barrier" [5]. In [1] we have measured the overhead of this approach relative to having mitigations off and including the upstream Spectre v4 mitigations. For event tracing and stack-sampling profilers, we found that mitigations increase BPF program execution time by 0% to 62%. For the Loxilb network load balancer, we have measured a 14% slowdown in SCTP performance but no significant slowdown for TCP. This overhead only applies to programs that were previously rejected. I reran the expressiveness-evaluation with v6.14 and made sure the main results still match those from [1] and [2] (which used v6.5). Main design decisions are: * Do not use separate bytecode insns for v1 and v4 barriers. This simplifies the verifier significantly and has the only downside that performance on PowerPC is not as high as it could be. * Allow archs to still disable v1/v4 mitigations separately by setting bpf_jit_bypass_spec_v1/v4(). This has the benefit that archs can benefit from improved BPF expressiveness / performance if they are not vulnerable (e.g., ARM64 for v4 in the kernel). * Do not remove the empty BPF_NOSPEC implementation for backends for which it is unknown whether they are vulnerable to Spectre v1.

This series therefore no longer changes push_stack() to return PTR_ERR. - Add detailed explanation of how lfence works internally and how it affects the algorithm. - Add tests checking that nospec instructions are inserted in expected locations using __xlated_unpriv as suggested by Eduard (also, include a fix for __xlated_unpriv) - Add a test for the mitigations from the description of commit 9183671af6db ("bpf: Fix leakage under speculation on mispredicted branches") - Remove unused variables from do_check[_insn]() as suggested by Eduard. - Remove INSN_IDX_MODIFIED to improve readability as suggested by Eduard. This also causes the nospec_result-check to run (and fail) for jumping-ops. Add a warning to assert that this check must never succeed in that case. - Add details on the safety of patch 10 ("bpf: Allow nospec-protected var-offset stack access") based on the feedback on v1. - Rebase to bpf-next-250420 - Link to v1: https://lore.kernel.org/all/20250313172127.1098195-1-luis.gerhorst@fau.de/ * RFC -> v1: - rebase to bpf-next-250313 - tests: mark expected successes/new errors - add bpt_jit_bypass_spec_v1/v4() to avoid #ifdef in bpf_bypass_spec_v1/v4() - ensure that nospec with v1-support is implemented for archs for which GCC supports speculation barriers, except for MIPS - arm64: emit speculation barrier - powerpc: change nospec to include v1 barrier - discuss potential security (archs that do not impl.
