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.
