Thanks David !
From: Eric Dumazet <edumazet@google.com> Mostly small improvements in this series. The notable change is in "defer skb freeing after socket lock is released" in recvmsg() (and RX zerocopy) The idea is to try to let skb freeing to BH handler, whenever possible, or at least perform the freeing outside of the socket lock section, for much improved performance. This idea can probably be extended to other protocols. Tests on a 100Gbit NIC Max throughput for one TCP_STREAM flow, over 10 runs. MTU : 1500 (1428 bytes of TCP payload per MSS) Before: 55 Gbit After: 66 Gbit MTU : 4096+ (4096 bytes of TCP payload, plus TCP/IPv6 headers) Before: 82 Gbit After: 95 Gbit Eric Dumazet (20): tcp: minor optimization in tcp_add_backlog() tcp: remove dead code in __tcp_v6_send_check() tcp: small optimization in tcp_v6_send_check() net: use sk_is_tcp() in more places net: remove sk_route_forced_caps net: remove sk_route_nocaps ipv6: shrink struct ipcm6_cookie net: shrink struct sock by 8 bytes net: forward_alloc_get depends on CONFIG_MPTCP net: cache align tcp_memory_allocated, tcp_sockets_allocated tcp: small optimization in tcp recvmsg() tcp: add RETPOLINE mitigation to sk_backlog_rcv tcp: annotate data-races on tp->segs_in and tp->data_segs_in tcp: annotate races around tp->urg_data tcp: tp->urg_data is unlikely to be set tcp: avoid indirect calls to sock_rfree tcp: defer skb freeing after socket lock is released tcp: check local var (timeo) before socket fields in one test tcp: do not call tcp_cleanup_rbuf() if we have a backlog net: move early demux fields close to sk_refcnt include/linux/skbuff.h | 2 + include/linux/skmsg.h | 6 --- include/net/ip6_checksum.h | 12 ++--- include/net/ipv6.h | 4 +- include/net/sock.h | 51 +++++++++++++-------- include/net/tcp.h | 18 +++++++- net/core/skbuff.c | 6 +-- net/core/sock.c | 18 +++++--- net/ipv4/tcp.c | 91 ++++++++++++++++++++++++++------------ net/ipv4/tcp_input.c | 8 ++-- net/ipv4/tcp_ipv4.c | 10 ++--- net/ipv4/tcp_output.c | 2 +- net/ipv4/udp.c | 2 +- net/ipv6/ip6_output.c | 2 +- net/ipv6/tcp_ipv6.c | 10 ++--- net/mptcp/protocol.c | 2 +- 16 files changed, 149 insertions(+), 95 deletions(-)
