Changes since v3: - split bpf_xdp_ct_add in bpf_xdp_ct_alloc/bpf_skb_ct_alloc and bpf_ct_insert_entry - add verifier code to properly populate/configure ct entry - improve selftests Changes since v2: - add bpf_xdp_ct_add and bpf_ct_refresh_timeout kfunc helpers - remove conntrack dependency from selftests - add support for forcing kfunc args to be referenced and related selftests Changes since v1: - add bpf_ct_refresh_timeout kfunc selftest Kumar Kartikeya Dwivedi (11): bpf: Add support for forcing kfunc args to be referenced bpf: Print multiple type flags in verifier log bpf: Support rdonly PTR_TO_BTF_ID for pointer to const return value bpf: Support storing rdonly PTR_TO_BTF_ID in BPF maps bpf: Support passing rdonly PTR_TO_BTF_ID to kfunc bpf: Whitelist some fields in nf_conn for BPF_WRITE bpf: Define acquire-release pairs for kfuncs selftests/bpf: Add verifier tests for forced kfunc ref args selftests/bpf: Add C tests for rdonly PTR_TO_BTF_ID selftests/bpf: Add verifier tests for rdonly PTR_TO_BTF_ID selftests/bpf: Add negative tests for bpf_nf Lorenzo Bianconi (3): net: netfilter: add kfunc helper to update ct timeout net: netfilter: add kfunc helpers to alloc and insert a new ct entry selftests/bpf: add selftest for bpf_xdp_ct_add and bpf_ct_refresh_timeout kfunc include/linux/bpf.h | 17 +- include/linux/bpf_verifier.h | 1 + include/linux/btf.h | 40 ++ include/linux/filter.h | 3 + include/net/netfilter/nf_conntrack.h | 1 + include/net/netfilter/nf_conntrack_bpf.h | 5 + include/uapi/linux/bpf.h | 2 +- kernel/bpf/btf.c | 206 ++++++++-- kernel/bpf/helpers.c | 4 +- kernel/bpf/verifier.c | 110 ++++-- net/bpf/test_run.c | 20 +- net/core/filter.c | 28 ++ net/netfilter/nf_conntrack_bpf.c | 367 ++++++++++++++++-- net/netfilter/nf_conntrack_core.c | 23 +- tools/include/uapi/linux/bpf.h | 2 +- .../testing/selftests/bpf/prog_tests/bpf_nf.c | 58 ++- .../selftests/bpf/prog_tests/map_kptr.c | 9 +- tools/testing/selftests/bpf/progs/map_kptr.c | 31 +- .../selftests/bpf/progs/map_kptr_fail.c | 114 ++++++ .../testing/selftests/bpf/progs/test_bpf_nf.c | 87 ++++- .../selftests/bpf/progs/test_bpf_nf_fail.c | 73 ++++ tools/testing/selftests/bpf/test_verifier.c | 17 +- tools/testing/selftests/bpf/verifier/calls.c | 53 +++ .../testing/selftests/bpf/verifier/map_kptr.c | 156 ++++++++ 24 files changed, 1276 insertions(+), 151 deletions(-) create mode 100644 tools/testing/selftests/bpf/progs/test_bpf_nf_fail.c -- 2.35.3
