It was not useful before\n and now pdump depends on bpf.\n\nv4:\n - minor checkpatch fixes.\n Note: some of the checkpatch warnings are bogus and won't be fixed.\n - fix build of dumpcap on FreeBSD\n\nv3:\n - introduce packet filters using classic BPF to eBPF converter\n required small fix to DPDK BPF interpreter\n - introduce function to decode eBPF instructions\n - add option to dumpcap to show both classic BPF and eBPF result\n - drop some un-useful stubs\n - minor checkpatch warning cleanup\n\nv2:\n fix formatting of packet blocks\n fix the new packet capture statistics\n fix crash when primary process exits\n record start/end time\n various whitespace/checkpatch warnings\n\nStephen Hemminger (12):\n lib: pdump is not supported on Windows\n librte_pcapng: add new library for writing pcapng files\n bpf: allow self-xor operation\n bpf: add function to convert classic BPF to DPDK BPF\n bpf: add function to dump eBPF instructions\n pdump: support pcapng and filtering\n app/dumpcap: add new packet capture application\n test: add test for bpf_convert\n test: add a test for pcapng library\n test: enable bpf autotest\n doc: changes for new pcapng and dumpcap utility\n MAINTAINERS: add entry for new packet capture features\n\n MAINTAINERS | 11 +-\n app/dumpcap/main.c | 844 ++++++++++++++++++\n app/dumpcap/meson.build | 16 +\n app/meson.build | 1 +\n app/test/meson.build | 6 +\n app/test/test_bpf.c | 200 +++++\n app/test/test_pcapng.c | 272 ++++++\n doc/api/doxy-api-index.md | 1 +\n doc/api/doxy-api.conf.in | 1 +\n .../howto/img/packet_capture_framework.svg | 96 +-\n doc/guides/howto/packet_capture_framework.rst | 69 +-\n doc/guides/prog_guide/index.rst | 1 +\n doc/guides/prog_guide/pcapng_lib.rst | 25 +\n doc/guides/prog_guide/pdump_lib.rst | 28 +-\n doc/guides/rel_notes/release_21_11.rst | 10 +\n doc/guides/tools/dumpcap.rst | 86 ++\n doc/guides/tools/index.rst | 1 +\n lib/bpf/bpf_convert.c | 575 ++++++++++++\n lib/bpf/bpf_dump.c | 139 +++\n lib/bpf/bpf_validate.c | 9 +-\n lib/bpf/meson.build | 6 +\n lib/bpf/rte_bpf.h | 39 +\n lib/bpf/version.map | 7 +\n lib/meson.build | 6 +-\n lib/pcapng/meson.build | 8 +\n lib/pcapng/pcapng_proto.h | 129 +++\n lib/pcapng/rte_pcapng.c | 607 +++++++++++++\n lib/pcapng/rte_pcapng.h | 196 ++++\n lib/pcapng/version.map | 12 +\n lib/pdump/meson.build | 2 +-\n lib/pdump/rte_pdump.c | 432 ++++++---\n lib/pdump/rte_pdump.h | 113 ++-\n lib/pdump/version.map | 8 +\n 33 files changed, 3737 insertions(+), 219 deletions(-)\n create mode 100644 app/dumpcap/main.c\n create mode 100644 app/dumpcap/meson.build\n create mode 100644 app/test/test_pcapng.c\n create mode 100644 doc/guides/prog_guide/pcapng_lib.rst\n create mode 100644 doc/guides/tools/dumpcap.rst\n create mode 100644 lib/bpf/bpf_convert.c\n create mode 100644 lib/bpf/bpf_dump.c\n create mode 100644 lib/pcapng/meson.build\n create mode 100644 lib/pcapng/pcapng_proto.h\n create mode 100644 lib/pcapng/rte_pcapng.c\n create mode 100644 lib/pcapng/rte_pcapng.h\n create mode 100644 lib/pcapng/version.map" }
