Radek Pazdera 95e1ffd564 ip.7: Document IP_MULTICAST_ALL 
This commit adds documentation for the IP_MULTICAST_ALL socket
option.

The option was added to the Linux kernel in 2.6.31:

    Author Nivedita Singhvi <niv@us.ibm.com>
    Commit f771bef98004d9d141b085d987a77d06669d4f4f

The description is based on a previous one [3] posted by the
original author of the code -- Nivedita, but it is slightly
re-worded.

I tested it myself and it works as described.

Flavio Leitner 0a03fceb09 ip.7: Improve explanation about calling listen() or connect() 
Problem:
When connect(2) is executed, the local port number may duplicate.

How reproducible:
When using parameter "net.ipv4.ip_local_port_range", a client may use
the same port to connect to the different sessions on the localhost.

Steps to Reproduce:
1.Change "net.ipv4.ip_local_port_range".
  [Example]
  net.ipv4.ip_local_port_range = 32768 32770

2.Connect to any two ports of LISTEN by telnet command.
  [Example]
  # netstat -antp | grep LISTEN
  tcp        0      0 0.0.0.0:139                 0.0.0.0:*                   LISTEN      2828/smbd
  tcp        0      0 0.0.0.0:21                  0.0.0.0:*                   LISTEN      2800/vsftpd
  #
  # telnet 127.0.0.1 139
  # telnet 127.0.0.1 21
  # telnet 127.0.0.1 21

3.Duplication of a local transmission port.
  [Example]
  # netstat -antp
  tcp        0      0 127.0.0.1:32769      127.0.0.1:139      ESTABLISHED 18147/telnet
  tcp        0      0 127.0.0.1:32769      127.0.0.1:21       ESTABLISHED 18157/telnet

Actual results:
The local port number may duplicate.

Expected results:
The local port number doesn't duplicate.

Additional info:
[Investigation]
"man 7 ip" contains following text:
-----------------------------------------------------------------
When listen(2) or connect(2) are called on an unbound socket, it
is automatically bound to a random  free  port  with the local
address set to INADDR_ANY.
-----------------------------------------------------------------

Although indicated as "it is automatically bound to a random free
port", the port number which is not free like in a reproduce
procedure may be bound.  Therefore, based on the description of
this "man 7 ip", it can be judged that it is bug to use the local
port where the process duplicated.

--- Comment by Leitner, Flavio on 2/7/2012 2:55 PM ---

It's allowed to have multiple tasks using the same port (as a
result of calling connect(2)) as long as the other connection
information (4-tuple) differs to resolve the conflict.  Thus,
it must be an unique 4-tuple consisting of source and
destination IP addresses and port numbers to not conflict.

In the example, the dest port is different.
          tcp        0      0 127.0.0.1:32769      127.0.0.1:139      ESTABLISHED 18147/telnet
          tcp        0      0 127.0.0.1:32769      127.0.0.1:21       ESTABLISHED 18157/telnet

  IP_BLOCK_SOURCE
  IP_UNBLOCK_SOURCE
  IP_MSFILTER

Benjamin Poirier 8341e3a766 ip.7: Improve description of IP_MTU_DISCOVER 
I noticed what appears to be a discrepancy between the ip(7)
man page and the kernel code with regards to the IP DF flag
for UDP sockets.

The man page says that "The don't-fragment flag is set on all
outgoing datagrams" and that the ip_no_pmtu_disc sysctl affects
only SOCK_STREAM sockets. This is quickly disproved by doing:

    echo 1 > /proc/sys/net/ipv4/ip_no_pmtu_disc

firing up netcat and looking at a few outgoing UDP packets in
wireshark (they don't have the DF flag set).

1) in the words of `man 7 ip`:
IP_MTU_DISCOVER (since Linux 2.2)
     Set or receive the Path MTU Discovery  setting  for  a  socket.
     When  enabled, Linux will perform Path MTU Discovery as defined
     in RFC 1191 on this socket.  The don't-fragment flag is set  on
     all  outgoing datagrams.  The system-wide default is controlled
     by the /proc/sys/net/ipv4/ip_no_pmtu_disc file for  SOCK_STREAM
     sockets, and disabled on all others.

2) in net/ipv4/af_inet.c:inet_create():
       if (ipv4_config.no_pmtu_disc)
               inet->pmtudisc = IP_PMTUDISC_DONT;
       else
               inet->pmtudisc = IP_PMTUDISC_WANT;

and pmtudisc is left alone from there on for UDP sockets.
