This is a first patchset for IPVS optimizations. Another patchset will address the locking in schedulers and moving the global _bh disabling from LOCAL_OUT to all locks. It is in TODO list. All patches are for net-next. The idea is after discussion and review Simon to apply the patchset to ipvs-next tree. The changes in this patchset eliminate locks and dst refcnt operations from packet processing by using RCU. There are more details in the patches. Julian Anastasov (12): net: add dst_get_noref and refdst_ptr helpers ipvs: avoid routing by TOS for real server ipvs: prefer NETDEV_DOWN event to free cached dsts ipvs: convert the IP_VS_XMIT macros to functions ipvs: rename functions related to dst_cache reset ipvs: optimize dst usage for real server ipvs: convert app locks ipvs: remove rs_lock by using RCU ipvs: convert locks used in persistence engines ipvs: convert connection locking ipvs: reorder keys in connection structure ipvs: avoid kmem_cache_zalloc in ip_vs_conn_new include/net/dst.h | 14 +- include/net/ip_vs.h | 56 +++-- net/netfilter/ipvs/ip_vs_app.c | 27 ++- net/netfilter/ipvs/ip_vs_conn.c | 254 +++++++++------- net/netfilter/ipvs/ip_vs_core.c | 16 +- net/netfilter/ipvs/ip_vs_ctl.c | 128 ++++---- net/netfilter/ipvs/ip_vs_ftp.c | 2 + net/netfilter/ipvs/ip_vs_pe.c | 43 +-- net/netfilter/ipvs/ip_vs_pe_sip.c | 1 + net/netfilter/ipvs/ip_vs_proto_sctp.c | 18 +- net/netfilter/ipvs/ip_vs_proto_tcp.c | 18 +- net/netfilter/ipvs/ip_vs_proto_udp.c | 19 +- net/netfilter/ipvs/ip_vs_xmit.c | 532 ++++++++++++++++++++------------- 13 files changed, 633 insertions(+), 495 deletions(-) -- 1.7.3.4 -- To unsubscribe from this list: send the line "unsubscribe lvs-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
