<content type='text'>
Add functionality to enable the port mapper on the passive side to provide to its
clients the actual (non-mapped) ip/tcp address information of the connecting peer

1) Adding remote_info_cb() to process the address info of the connecting peer
   The address info is provided by the user space port mapper service when
   the connection is initiated by the peer
2) Adding a hash list to store the remote address info
3) Adding functionality to add/remove the remote address info
   After the info has been provided to the port mapper client,
   it is removed from the hash list

<title>tcp: add TCP_CC_INFO socket option</title>

Some Congestion Control modules can provide per flow information,
but current way to get this information is to use netlink.

Like TCP_INFO, let's add TCP_CC_INFO so that applications can
issue a getsockopt() if they have a socket file descriptor,
instead of playing complex netlink games.

Sample usage would be :

  union tcp_cc_info info;
  socklen_t len = sizeof(info);

  if (getsockopt(fd, SOL_TCP, TCP_CC_INFO, &amp;info, &amp;len) == -1)

We would like that optional info provided by Congestion Control
modules using netlink can also be read using getsockopt()

This patch changes get_info() to put this information in a buffer,
instead of skb, like tcp_get_info(), so that following patch
can reuse this common infrastructure.

This patch tracks total number of payload bytes received on a TCP socket.
This is the sum of all changes done to tp-&gt;rcv_nxt

RFC4898 named this : tcpEStatsAppHCThruOctetsReceived

This is a 64bit field, and can be fetched both from TCP_INFO
getsockopt() if one has a handle on a TCP socket, or from inet_diag
netlink facility (iproute2/ss patch will follow)

Note that tp-&gt;bytes_received was placed near tp-&gt;rcv_nxt for
best data locality and minimal performance impact.

This is the sum of all changes done to tp-&gt;snd_una, and allows
for precise tracking of delivered data.

RFC4898 named this : tcpEStatsAppHCThruOctetsAcked

This is a 64bit field, and can be fetched both from TCP_INFO
getsockopt() if one has a handle on a TCP socket, or from inet_diag
netlink facility (iproute2/ss patch will follow)

Note that tp-&gt;bytes_acked was placed near tp-&gt;snd_una for
best data locality and minimal performance impact.
