      [IPV6]: Add ICMPMsgStats MIB (RFC 4293) [rev 2] · 14878f75
      David L Stevens 提交于
      Background: RFC 4293 deprecates existing individual, named ICMP
      type counters to be replaced with the ICMPMsgStatsTable. This table
      includes entries for both IPv4 and IPv6, and requires counting of all
      ICMP types, whether or not the machine implements the type.
      
      These patches "remove" (but not really) the existing counters, and
      replace them with the ICMPMsgStats tables for v4 and v6.
      It includes the named counters in the /proc places they were, but gets the
      values for them from the new tables. It also counts packets generated
      from raw socket output (e.g., OutEchoes, MLD queries, RA's from
      radvd, etc).
      
      Changes:
      1) create icmpmsg_statistics mib
      2) create icmpv6msg_statistics mib
      3) modify existing counters to use these
      4) modify /proc/net/snmp to add "IcmpMsg" with all ICMP types
              listed by number for easy SNMP parsing
      5) modify /proc/net/snmp printing for "Icmp" to get the named data
              from new counters.
      [new to 2nd revision]
      6) support per-interface ICMP stats
      7) use common macro for per-device stat macros

      [NET]: Make the device list and device lookups per namespace. · 881d966b
      Eric W. Biederman 提交于
      This patch makes most of the generic device layer network
      namespace safe.  This patch makes dev_base_head a
      network namespace variable, and then it picks up
      a few associated variables.  The functions:
      dev_getbyhwaddr
      dev_getfirsthwbytype
      dev_get_by_flags
      dev_get_by_name
      __dev_get_by_name
      dev_get_by_index
      __dev_get_by_index
      dev_ioctl
      dev_ethtool
      dev_load
      wireless_process_ioctl
      
      were modified to take a network namespace argument, and
      deal with it.
      
      vlan_ioctl_set and brioctl_set were modified so their
      hooks will receive a network namespace argument.
      
      So basically anthing in the core of the network stack that was
      affected to by the change of dev_base was modified to handle
      multiple network namespaces.  The rest of the network stack was
      simply modified to explicitly use &init_net the initial network
      namespace.  This can be fixed when those components of the network
      stack are modified to handle multiple network namespaces.
      
      For now the ifindex generator is left global.
      
      Fundametally ifindex numbers are per namespace, or else
      we will have corner case problems with migration when
      we get that far.
      
      At the same time there are assumptions in the network stack
      that the ifindex of a network device won't change.  Making
      the ifindex number global seems a good compromise until
      the network stack can cope with ifindex changes when
      you change namespaces, and the like.

      [NET]: Make socket creation namespace safe. · 1b8d7ae4
      Eric W. Biederman 提交于
      This patch passes in the namespace a new socket should be created in
      and has the socket code do the appropriate reference counting.  By
      virtue of this all socket create methods are touched.  In addition
      the socket create methods are modified so that they will fail if
      you attempt to create a socket in a non-default network namespace.
      
      Failing if we attempt to create a socket outside of the default
      network namespace ensures that as we incrementally make the network stack
      network namespace aware we will not export functionality that someone
      has not audited and made certain is network namespace safe.
      Allowing us to partially enable network namespaces before all of the
      exotic protocols are supported.
      
      Any protocol layers I have missed will fail to compile because I now
      pass an extra parameter into the socket creation code.

      [TCP]: Invoke tcp_sendmsg() directly, do not use inet_sendmsg(). · 3516ffb0
      David S. Miller 提交于
      As discovered by Evegniy Polyakov, if we try to sendmsg after
      a connection reset, we can do incredibly stupid things.
      
      The core issue is that inet_sendmsg() tries to autobind the
      socket, but we should never do that for TCP.  Instead we should
      just go straight into TCP's sendmsg() code which will do all
      of the necessary state and pending socket error checks.
      
      TCP's sendpage already directly vectors to tcp_sendpage(), so this
      merely brings sendmsg() in line with that.

      [IPV6] MIP6: Loadable module support for MIPv6. · 59fbb3a6
      Masahide NAKAMURA 提交于
      This patch makes MIPv6 loadable module named "mip6".
      
      Here is a modprobe.conf(5) example to load it automatically
      when user application uses XFRM state for MIPv6:
      
      alias xfrm-type-10-43 mip6
      alias xfrm-type-10-60 mip6
      
      Some MIPv6 feature is not included by this modular, however,
      it should not be affected to other features like either IPsec
      or IPv6 with and without the patch.
      We may discuss XFRM, MH (RAW socket) and ancillary data/sockopt
      separately for future work.
      
      Loadable features:
      * MH receiving check (to send ICMP error back)
      * RO header parsing and building (i.e. RH2 and HAO in DSTOPTS)
      * XFRM policy/state database handling for RO
      
      These are NOT covered as loadable:
      * Home Address flags and its rule on source address selection
      * XFRM sub policy (depends on its own kernel option)
      * XFRM functions to receive RO as IPv6 extension header
      * MH sending/receiving through raw socket if user application
        opens it (since raw socket allows to do so)
      * RH2 sending as ancillary data
      * RH2 operation with setsockopt(2)
