8 | .Sh SYNOPSIS | ||
9 | .In openssl/ssl.h | ||
10 | .Ft void | ||
11 | .Fn SSL_set_shutdown "SSL *ssl" "int mode" | ||
12 | .Ft int | ||
13 | .Fn SSL_get_shutdown "const SSL *ssl" | ||
14 | .Sh DESCRIPTION | ||
15 | .Fn SSL_set_shutdown | ||
16 | sets the shutdown state of | ||
17 | .Fa ssl | ||
18 | to | ||
19 | .Fa mode . | ||
20 | .Pp | ||
21 | .Fn SSL_get_shutdown | ||
22 | returns the shutdown mode of | ||
23 | .Fa ssl . | ||
24 | .Sh NOTES | ||
25 | The shutdown state of an ssl connection is a bitmask of: | ||
26 | .Bl -tag -width Ds | ||
27 | .It 0 | ||
28 | No shutdown setting, yet. | ||
29 | .It Dv SSL_SENT_SHUTDOWN | ||
30 | A | ||
31 | .Dq close notify | ||
32 | shutdown alert was sent to the peer; the connection is being considered closed | ||
33 | and the session is closed and correct. | ||
34 | .It Dv SSL_RECEIVED_SHUTDOWN | ||
35 | A shutdown alert was received form the peer, either a normal | ||
36 | .Dq close notify | ||
37 | or a fatal error. | ||
38 | .El | ||
39 | .Pp | ||
40 | .Dv SSL_SENT_SHUTDOWN | ||
41 | and | ||
42 | .Dv SSL_RECEIVED_SHUTDOWN | ||
43 | can be set at the same time. | ||
44 | .Pp | ||
45 | The shutdown state of the connection is used to determine the state of the | ||
46 | .Fa ssl | ||
47 | session. | ||
48 | If the session is still open when | ||
49 | .Xr SSL_clear 3 | ||
50 | or | ||
51 | .Xr SSL_free 3 | ||
52 | is called, it is considered bad and removed according to RFC2246. | ||
53 | The actual condition for a correctly closed session is | ||
54 | .Dv SSL_SENT_SHUTDOWN | ||
55 | (according to the TLS RFC, it is acceptable to only send the | ||
56 | .Dq close notify | ||
57 | alert but to not wait for the peer's answer when the underlying connection is | ||
58 | closed). | ||
59 | .Fn SSL_set_shutdown | ||
60 | can be used to set this state without sending a close alert to the peer (see | ||
61 | .Xr SSL_shutdown 3 ) . | ||
62 | .Pp | ||
63 | If a | ||
64 | .Dq close notify | ||
65 | was received, | ||
66 | .Dv SSL_RECEIVED_SHUTDOWN | ||
67 | will be set, but to set | ||
68 | .Dv SSL_SENT_SHUTDOWN | ||
69 | the application must still call | ||
70 | .Xr SSL_shutdown 3 | ||
71 | or | ||
72 | .Fn SSL_set_shutdown | ||
73 | itself. | ||
74 | .Sh RETURN VALUES | ||
75 | .Fn SSL_set_shutdown | ||
76 | does not return diagnostic information. | ||
77 | .Pp | ||
78 | .Fn SSL_get_shutdown | ||
79 | returns the current setting. | ||
