NAME

       knet_handle_enable_access_lists - Enable or disable usage of access lists (default: off)

SYNOPSIS

       #include <libknet.h>

       int knet_handle_enable_access_lists(
           knet_handle_t  knet_h,
           unsigned int   enabled
       );

DESCRIPTION

       knet_handle_enable_access_lists

       knet_h - pointer to knet_handle_t

       enable - set to 1 to use access lists, 0 to disable access_lists.

       access lists are bound to links. There are 2 types of links: 1) point to point, where both
       source and destinations are well known at configuration time. 2) open  links,  where  only
       the source is known at configuration time.

       knet will automatically generate access lists for point to point links.

       For   open   links,   knet   provides   4   API   calls   to   manipulate   access  lists:
       knet_link_add_acl(3),       knet_link_rm_acl(3),        knet_link_insert_acl(3)        and
       knet_link_clear_acl(3). Those API calls will work exclusively on open links as they are of
       no use on point to point links.

       knet   will   not   enforce   any   access   list   unless   specifically    enabled    by
       knet_handle_enable_access_lists(3).

       From a security / programming perspective we recommend:create the knet handle

       enable access lists

       configure hosts and links

       configure access lists for open links

RETURN VALUE

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