  • NAME
      ipsec_pf_key - lists PF_KEY sockets registered with KLIPS
  • SYNOPSIS
      cat /proc/net/pf_key
  • DESCRIPTION
      /proc/net/pf_key is a read-only file which lists the presently open PF_KEY sockets on the local system and their parameters.

      Each line lists one PF_KEY socket. A table entry consists of:
      +
      sock pointer (sock)
      +
      PID of the socket owner (pid)
      +
      flag to indicate if the socket is dead (d)
      +
      socket wait queue (sleep)
      +
      socket pointer (socket)
      +
      next socket in chain (next)
      +
      previous socket in chain (prev)
      +
      last socket error (e)
      +
      pointer to destruct routine (destruct)
      +
      is this a reused socket (r)
      +
      has this socket been zapped (z)
      +
      socket family to which this socket belongs (fa)
      +
      local port number (n)
      +
      protocol version number (p)
      +
      Receive queue bytes committed (r)
      +
      Transmit queue bytes committed (w)
      +
      option memory allocations (o)
      +
      size of send buffer in bytes (sndbf)
      +
      timestamp in seconds (stamp)
      +
      socket flags (Flags)
      +
      socket type (Type)
      +
      connection state (St)

      shows that there is one pf_key socket set up that starts at c3b8c140 , whose owning process has PID 3553 , the socket is not dead, its wait queue is at c0599818 , whose owning socket is at c05997fc , with no other sockets in the chain, no errors, no destructor, it is a reused socket which has not been zapped, from protocol family 15 (PF_KEY), local port number 0 , protocol socket version 2 , no memory allocated to transmit, receive or option queues, a send buffer of almost 64kB , a timestamp of 0.103232 , no flags set, type 3 , in state 1 .
