NAME

6       knet_link_add_acl - Add access list entry to an open link.

SYNOPSIS

9       #include <libknet.h>
10
11       int knet_link_add_acl(
12           knet_handle_t              knet_h,
13           knet_node_id_t             host_id,
14           uint8_t                    link_id,
15           struct sockaddr_storage   *ss1,
16           struct sockaddr_storage   *ss2,
17           check_type_t               type,
18           check_acceptreject_t       acceptreject
19       );

DESCRIPTION

22       knet_link_add_acl
23
24       knet_h - pointer to knet_handle_t
25
26       host_id - see knet_host_add(3)
27
28       link_id - see knet_link_set_config(3)
29
30       ss1 / ss2 / type / acceptreject - see typedef definitions for details
31
32       IMPORTANT: the order in which access lists are added is critical and it
33       is left to the user to add them in  the  right  order.  knet  will  not
34       attempt to logically sort them.
35
36       For example: 1 - accept from 10.0.0.0/8 2 - reject from 10.0.0.1/32
37
38       is not the same as:
39
40       1 - reject from 10.0.0.1/32 2 - accept from 10.0.0.0/8
41
42       In  the  first  example, rule number 2 will never match because packets
43       from 10.0.0.1 will be accepted by rule number 1.

STRUCTURES

46       enum check_type_t {
47             CHECK_TYPE_ADDRESS;
48             CHECK_TYPE_MASK;
49             CHECK_TYPE_RANGE;
50       };
51       enum check_acceptreject_t {
52             CHECK_ACCEPT;
53             CHECK_REJECT;
54       };
55

RETURN VALUE

57       knet_link_add_acl returns 0 on success. -1 on error and errno is set.
