[PATCH v2 0/4] add tests to verify IFS (In Field Scan) driver functionality

by Pengfei Xu

To verify IFS (In Field Scan [1]) driver functionality, add the following 6 test cases: 1. Verify that IFS sysfs entries are created after loading the IFS module 2. Check if loading an invalid IFS test image fails and loading a valid one succeeds 3. Perform IFS scan test on each CPU using all the available image files 4. Perform IFS scan with first test image file on a random CPU for 3 rounds 5. Perform IFS ARRAY BIST(Board Integrated System Test) test on each CPU 6. Perform IFS ARRAY BIST test on a random CPU for 3 rounds These are not exhaustive, but some minimal test runs to check various parts of the driver. Some negative tests are also included.

[PATCH v3 0/6] cleanups, fixes, and progress towards avoiding "make headers"

by John Hubbard

Changes since v2: a) After some disussion with David Hildenbrand, simplified the "fix missing __NR_mseal" patch down to just two lines of diff, after all. b) Improved the "kvm, mdwe fixes to avoid requiring "make headers"" patch by taking a snapshot of the prctl.h, instead of manually creating defines. Thanks also to David Hildenbrand for that. c) Fixed up the final patch to use asm-generic/unistd.h. d) Added acks. e) Rebased onto 6.10-rc4+ (today's top of tree). Changes since v1: Jeff Xu, I apologize for this churn: I was forced to drop your Reviewed-by and Tested-by tags from 2 of the 3 mseal patches, because the __NR_mseal fix is completely different now. a) Reworked the mseal fix to use the kernel's in-tree unistd*.h files, instead of hacking in a __NR_mseal definition directly. (Thanks to David Hildenbrand for pointing out that this needed to be done.) b) Fixed the subject line of the kvm and mdwe patch. c) Reordered the patches so as to group the mseal changes together. d) ADDED an additional patch, 6/6, to remove various __NR_xx items and checks from the mm selftests. Cover letter, updated for v2: Eventually, once the build succeeds on a sufficiently old distro, the idea is to delete $(KHDR_INCLUDES) from the selftests/mm build, and then after that, from selftests/lib.mk and all of the other selftest builds. For now, this series merely achieves a clean build of selftests/mm on a not-so-old distro: Ubuntu 23.04. In other words, after this series is applied, it is possible to delete $(KHDR_INCLUDES) from selftests/mm/Makefile and the build will still succeed. 1. Add tools/uapi/asm/unistd_[32|x32|64].h files, which include definitions of __NR_mseal, and include them (indirectly) from the files that use __NR_mseal. The new files are copied from ./usr/include/asm, which is how we have agreed to do this sort of thing, see [1]. 2. Add fs.h, similarly created: it was copied directly from a snapshot of ./usr/include/linux/fs.h after running "make headers". 3. Add a few selected prctl.h values that the ksm and mdwe tests require. 4. Factor out some common code from mseal_test.c and seal_elf.c, into a new mseal_helpers.h file. 5. Remove local __NR_* definitions and checks.

[PATCH bpf-next v4 00/12] bpf: Support dumping kfunc prototypes from BTF

by Daniel Xu

This patchset enables both detecting as well as dumping compilable prototypes for kfuncs. The first commit instructs pahole to DECL_TAG kfuncs when available. This requires v1.27 or newer. v1.27 is nearing release at time of writing. Following this, users will be able to look at BTF inside vmlinux (or modules) and check if the kfunc they want is available. The final commit teaches bpftool how to dump kfunc prototypes. This is done for developer convenience. The rest of the commits are fixups to enable selftests to use the newly dumped kfunc prototypes. With these, selftests will regularly exercise the newly added codepaths. === Changelog === From v3: * Teach selftests to use dumped prototypes From v2: * Update Makefile.btf with pahole flag * More error checking * Output formatting changes * Drop already-merged commit From v1: * Add __weak annotation * Use btf_dump for kfunc prototypes * Update kernel bpf_rdonly_cast() signature Daniel Xu (12): kbuild: bpf: Tell pahole to DECL_TAG kfuncs bpf: selftests: Fix bpf_iter_task_vma_new() prototype bpf: selftests: Fix fentry test kfunc prototypes bpf: selftests: Fix bpf_cpumask_first_zero() kfunc prototype bpf: selftests: Fix bpf_map_sum_elem_count() kfunc prototype bpf: selftests: Fix bpf_session_cookie() kfunc prototype bpf: selftests: Namespace struct_opt callbacks in bpf_dctcp bpf: verifier: Relax caller requirements for kfunc projection type args bpf: treewide: Align kfunc signatures to prog point-of-view bpf: selftests: nf: Opt out of using generated kfunc prototypes bpf: selftests: xfrm: Opt out of using generated kfunc prototypes bpftool: Support dumping kfunc prototypes from BTF fs/verity/measure.c | 3 +- include/linux/bpf.h | 8 +-- kernel/bpf/crypto.c | 24 +++++--- kernel/bpf/helpers.c | 39 +++++++++---- kernel/bpf/verifier.c | 12 +++- kernel/trace/bpf_trace.c | 9 ++- net/core/filter.c | 32 +++++++---- scripts/Makefile.btf | 2 +- tools/bpf/bpftool/btf.c | 55 +++++++++++++++++++ .../testing/selftests/bpf/bpf_experimental.h | 2 +- tools/testing/selftests/bpf/bpf_kfuncs.h | 2 +- tools/testing/selftests/bpf/progs/bpf_dctcp.c | 36 ++++++------ .../selftests/bpf/progs/get_func_ip_test.c | 14 ++--- .../selftests/bpf/progs/ip_check_defrag.c | 10 ++-- .../bpf/progs/kprobe_multi_session_cookie.c | 2 +- .../selftests/bpf/progs/map_percpu_stats.c | 2 +- .../selftests/bpf/progs/nested_trust_common.h | 2 +- .../testing/selftests/bpf/progs/test_bpf_nf.c | 1 + .../selftests/bpf/progs/test_bpf_nf_fail.c | 1 + .../bpf/progs/verifier_netfilter_ctx.c | 6 +- .../selftests/bpf/progs/xdp_synproxy_kern.c | 1 + tools/testing/selftests/bpf/progs/xfrm_info.c | 1 + 22 files changed, 183 insertions(+), 81 deletions(-) -- 2.44.0

[PATCH net-next 0/7] selftests: net: Switch pmtu.sh to use the internal ovs script.

by Aaron Conole

Currently, if a user wants to run pmtu.sh and cover all the provided test cases, they need to install the Open vSwitch userspace utilities. This dependency is difficult for users as well as CI environments, because the userspace build and setup may require lots of support and devel packages to be installed, system setup to be correct, and things like permissions and selinux policies to be properly configured. The kernel selftest suite includes an ovs-dpctl.py utility which can interact with the openvswitch module directly. This lets developers and CI environments run without needing too many extra dependencies - just the pyroute2 python package. This series enhances the ovs-dpctl utility to provide support for set() and tunnel() flow specifiers, better ipv6 handling support, and the ability to add tunnel vports, and LWT interfaces. Finally, it modifies the pmtu.sh script to call the ovs-dpctl.py utility rather than the typical OVS userspace utilities. Aaron Conole (7): selftests: openvswitch: Support explicit tunnel port creation. selftests: openvswitch: Refactor actions parsing. selftests: openvswitch: Add set() and set_masked() support. selftests: openvswitch: Add support for tunnel() key. selftests: openvswitch: Support implicit ipv6 arguments. selftests: net: Use the provided dpctl rather than the vswitchd for tests. selftests: net: add config for openvswitch tools/testing/selftests/net/config | 5 + .../selftests/net/openvswitch/ovs-dpctl.py | 372 +++++++++++++++--- tools/testing/selftests/net/pmtu.sh | 145 +++++-- 3 files changed, 453 insertions(+), 69 deletions(-) -- 2.45.1
