DESCRIPTION

16       /proc/net/pf_key is a read-only file that lists the presently open
17       PF_KEY sockets on the local system and their parameters.
18
19       Each line lists one PF_KEY socket. A table entry consists of:
20
21       +
22           sock pointer (sock)
23
24       +
25           PID of the socket owner (pid)
26
27       +
28           flag to indicate if the socket is dead (d)
29
30       +
31           socket wait queue (sleep)
32
33       +
34           socket pointer (socket)
35
36       +
37           next socket in chain (next)
38
39       +
40           previous socket in chain (prev)
41
42       +
43           last socket error (e)
44
45       +
46           pointer to destruct routine (destruct)
47
48       +
49           is this a reused socket (r)
50
51       +
52           has this socket been zapped (z)
53
54       +
55           socket family to which this socket belongs (fa)
56
57       +
58           local port number (n)
59
60       +
61           protocol version number (p)
62
63       +
64           Receive queue bytes committed (r)
65
66       +
67           Transmit queue bytes committed (w)
68
69       +
70           option memory allocations (o)
71
72       +
73           size of send buffer in bytes (sndbf)
74
75       +
76           timestamp in seconds (stamp)
77
78       +
79           socket flags (Flags)
80
81       +
82           socket type (Type)
83
84       +
85           connection state (St)

EXAMPLES

88       c3b8c140 3553 0 c0599818 c05997fc 0 0 0 0 1 0 15 0 2 0 0 0 65535

91       shows that there is one pf_key socket set up that starts at c3b8c140,
92       whose owning process has PID 3553, the socket is not dead, its wait
93       queue is at c0599818, whose owning socket is at c05997fc, with no other
94       sockets in the chain, no errors, no destructor, it is a reused socket
95       that has not been zapped, from protocol family 15 (PF_KEY), local port
96       number 0, protocol socket version 2, no memory allocated to transmit,
97       receive or option queues, a send buffer of almost 64kB, a timestamp of
98       0.103232, no flags set, type 3, in state 1.
