Proposal for proc/net/tcp Parser

[AlvinSolomon]

I built a parser for the proc/net/tcp file. This would fit well with all the other parsers that exist for proc/net/ files. Not all of the headers are included in the file, so they were gathered from Linux kernel documentation.

Here is the schema I'm using:

[
      {
        "sl":                           string,
        "local_address":                string,
        "rem_address":                  string,
        "st":                           string,
        "tx_queue":                     string,
        "rx_queue":                     string,
        "tr":                           string,
        "tm->when":                     string,
        "retrnsmt":                     string,
        "uid":                          string,
        "timeout":                      string,
        "inode":                        string,
        "sock_ref_count":               string,
        "sock_mem_loc":                 string,
        "retransmit_timeout":           string,
        "soft_clock_tick":              string,
        "(ack.quick<<1)|ack.pingpong":  string,
        "sending_congestion_window":    string,
        "slow_start_size_threshold":    string
      }
    ]

So if you had a file like this:

  sl  local_address rem_address   st tx_queue rx_queue tr tm->when retrnsmt   uid  timeout inode                                                     
   0: 3500007F:0035 00000000:0000 0A 00000000:00000000 00:00000000 00000000   101        0 34000 1 0000000000000000 100 0 0 10 5                     
   1: 0100007F:89E7 00000000:0000 0A 00000000:00000000 00:00000000 00000000  1000        0 140054 1 0000000000000000 100 0 0 10 0                    
   2: 0100007F:0277 00000000:0000 0A 00000000:00000000 00:00000000 00000000     0        0 34523 1 0000000000000000 100 0 0 10 0                     
   3: 802AA8C0:D450 2104C798:01BB 08 00000000:00000052 02:00000A6F 00000000  1000        0 149098 2 0000000000000000 20 4 0 10 -1                    

JC could output this:

Very nice! Thank you for the contribution. I’ll take a closer look in the next few days and this should make it in the next release.
