This is a series of fixes and tests for BPF functionality. The new tests for Tx and Rx filtering require the infrastructure to build a bpf program (clang) and the tool to convert object file to header (xxd). If missing the test will get skipped.
It is disappointing that there were no examples or tests when the code was submitted. v4 - review feedback - use alloca instead of burst to remove dependency on VLA v3 - do not depend on xxd -n flag which is not present on older versions Stephen Hemminger (5): bpf: add allocation annotations to functions bpf: use bulk free on filtered packets bpf: add a test for BPF ELF load bpf: add test for Rx and Tx filtering bpf: replace use of VLA app/test/bpf/filter.c | 53 +++++ app/test/bpf/load.c | 62 ++++++ app/test/bpf/meson.build | 53 +++++ app/test/meson.build | 2 + app/test/test_bpf.c | 451 +++++++++++++++++++++++++++++++++++++++ lib/bpf/bpf_pkt.c | 15 +- lib/bpf/rte_bpf.h | 11 +- 7 files changed, 636 insertions(+), 11 deletions(-) create mode 100644 app/test/bpf/filter.c create mode 100644 app/test/bpf/load.c create mode 100644 app/test/bpf/meson.build -- 2.51.0
