This patchset does not add any new feature or change any functionality 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. To see the big picture, 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 --- v7: add 1 trivial cleanup patch define a mask for sk_redir fix CONFIG_BPF_SYSCALL in include/net/udp.h make sk_psock_done_strp() static move skb_bpf_redirect_clear() to sk_psock_backlog() v6: fix !CONFIG_INET case v5: improve CONFIG_BPF_SYSCALL dependency add 3 trivial cleanup patches v4: reuse skb dst instead of skb ext fix another Kconfig error v3: fix a few Kconfig compile errors remove an unused variable add a comment for bpf_convert_data_end_access() 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 (9): bpf: clean up sockmap related Kconfigs skmsg: get rid of struct sk_psock_parser bpf: compute data_end dynamically with JIT code skmsg: move sk_redir from TCP_SKB_CB to skb sock_map: rename skb_parser and skb_verdict sock_map: make sock_map_prog_update() static skmsg: make __sk_psock_purge_ingress_msg() static skmsg: get rid of sk_psock_bpf_run() skmsg: remove unused sk_psock_stop() declaration include/linux/bpf.h | 29 +-- include/linux/bpf_types.h | 6 +- include/linux/skbuff.h | 3 + include/linux/skmsg.h | 82 +++++-- include/net/tcp.h | 41 +--- include/net/udp.h | 4 +- init/Kconfig | 1 + net/Kconfig | 6 +- net/core/Makefile | 6 +- net/core/filter.c | 48 ++-- net/core/skmsg.c | 212 +++++++++--------- net/core/sock_map.c | 77 +++---- net/ipv4/Makefile | 2 +- net/ipv4/tcp_bpf.c | 4 +- .../selftests/bpf/prog_tests/sockmap_listen.c | 8 +- .../selftests/bpf/progs/test_sockmap_listen.c | 4 +- 16 files changed, 274 insertions(+), 259 deletions(-) -- 2.25.1
