      [TCP]: SNMPv2 tcpAttemptFails counter error · 3687b1dc
      Wei Yongjun 提交于
      Refer to RFC2012, tcpAttemptFails is defined as following:
        tcpAttemptFails OBJECT-TYPE
            SYNTAX      Counter32
            MAX-ACCESS  read-only
            STATUS      current
            DESCRIPTION
                    "The number of times TCP connections have made a direct
                    transition to the CLOSED state from either the SYN-SENT
                    state or the SYN-RCVD state, plus the number of times TCP
                    connections have made a direct transition to the LISTEN
                    state from the SYN-RCVD state."
            ::= { tcp 7 }
      
      When I lookup into RFC793, I found that the state change should occured
      under following condition:
        1. SYN-SENT -> CLOSED
           a) Received ACK,RST segment when SYN-SENT state.
      
        2. SYN-RCVD -> CLOSED
           b) Received SYN segment when SYN-RCVD state(came from LISTEN).
           c) Received RST segment when SYN-RCVD state(came from SYN-SENT).
           d) Received SYN segment when SYN-RCVD state(came from SYN-SENT).
      
        3. SYN-RCVD -> LISTEN
           e) Received RST segment when SYN-RCVD state(came from LISTEN).
      
      In my test, those direct state transition can not be counted to
      tcpAttemptFails.

      [IPV6]: Audit all ip6_dst_lookup/ip6_dst_store calls · 497c615a
      Herbert Xu 提交于
      The current users of ip6_dst_lookup can be divided into two classes:
      
      1) The caller holds no locks and is in user-context (UDP).
      2) The caller does not want to lookup the dst cache at all.
      
      The second class covers everyone except UDP because most people do
      the cache lookup directly before calling ip6_dst_lookup.  This patch
      adds ip6_sk_dst_lookup for the first class.
      
      Similarly ip6_dst_store users can be divded into those that need to
      take the socket dst lock and those that don't.  This patch adds
      __ip6_dst_store for those (everyone except UDP/datagram) that don't
      need an extra lock.

      [IPV6]: Added GSO support for TCPv6 · f83ef8c0
      Herbert Xu 提交于
      This patch adds GSO support for IPv6 and TCPv6.  This is based on a patch
      by Ananda Raju <Ananda.Raju@neterion.com>.  His original description is:
      
      	This patch enables TSO over IPv6. Currently Linux network stacks
      	restricts TSO over IPv6 by clearing of the NETIF_F_TSO bit from
      	"dev->features". This patch will remove this restriction.
      
      	This patch will introduce a new flag NETIF_F_TSO6 which will be used
      	to check whether device supports TSO over IPv6. If device support TSO
      	over IPv6 then we don't clear of NETIF_F_TSO and which will make the
      	TCP layer to create TSO packets. Any device supporting TSO over IPv6
      	will set NETIF_F_TSO6 flag in "dev->features" along with NETIF_F_TSO.
      
      	In case when user disables TSO using ethtool, NETIF_F_TSO will get
      	cleared from "dev->features". So even if we have NETIF_F_TSO6 we don't
      	get TSO packets created by TCP layer.
      
      	SKB_GSO_TCPV4 renamed to SKB_GSO_TCP to make it generic GSO packet.
      	SKB_GSO_UDPV4 renamed to SKB_GSO_UDP as UFO is not a IPv4 feature.
      	UFO is supported over IPv6 also
      
      	The following table shows there is significant improvement in
      	throughput with normal frames and CPU usage for both normal and jumbo.
