From: Cong Wang <redacted> This patchset is the first series of patches separated out from the original large patchset, to make reviews easier. This patchset does not add any new feature but merely cleans up the existing sockmap and skmsg code and refactors it, to prepare for the patches followed up. This passed all BPF selftests. The original whole patchset is available on github: https://github.com/congwang/linux/tree/sockmap and this patchset is also available on github: https://github.com/congwang/linux/tree/sockmap1 --- v2: split the original patchset compute data_end with bpf_convert_data_end_access() get rid of psock->bpf_running reduce the scope of CONFIG_BPF_STREAM_PARSER do not add CONFIG_BPF_SOCK_MAP Cong Wang (5): bpf: clean up sockmap related Kconfigs skmsg: get rid of struct sk_psock_parser bpf: compute data_end dynamically with JIT code skmsg: use skb ext instead of TCP_SKB_CB sock_map: rename skb_parser and skb_verdict include/linux/bpf.h | 20 +- include/linux/bpf_types.h | 2 - include/linux/skbuff.h | 3 + include/linux/skmsg.h | 78 ++++++-- include/net/tcp.h | 29 +-- include/net/udp.h | 4 +- init/Kconfig | 1 + net/Kconfig | 7 +- net/core/Makefile | 2 +- net/core/filter.c | 46 +++-- net/core/skbuff.c | 7 + net/core/skmsg.c | 187 +++++++++--------- net/core/sock_map.c | 74 +++---- net/ipv4/Makefile | 2 +- net/ipv4/tcp_bpf.c | 2 - .../selftests/bpf/prog_tests/sockmap_listen.c | 8 +- .../selftests/bpf/progs/test_sockmap_listen.c | 4 +- 17 files changed, 252 insertions(+), 224 deletions(-) -- 2.25.1
