Data Fields
int(*	get_app_interface_cookie )(const char *interface_name, int linux_ifindex, uint32_t *cookie)
	Get application specific cookie for relevant LINUX tap interfaces. This helps application to work with its own notion of tap interface instead of something else defined by library. Cookie is passed to all subsequent function ops for any ip_addr, ip_route, ip_neigh and link updates. If application does not sets cookie, default value is DAO_NETLINK_APP_IF_COOKIE_INITIALIZER.
int(*	ip_local_addr_add_del )(dao_netlink_route_ip_addr_t *dao_ip_addr, int is_add)
	Add or delete Local IP address to interface.

Detailed Description

High level route netlink ops for getting

• Route Updates (See ip_route_add_del)
• Link Updates (See link_local_add_del)
• Neighbor Updates (See ip_neigh_add_del)
• IP Addr Updates (See ip_local_addr_add_del)

Field Documentation

get_app_interface_cookie

int(* get_app_interface_cookie) (const char *interface_name, int linux_ifindex, uint32_t *cookie)

Get application specific cookie for relevant LINUX tap interfaces. This helps application to work with its own notion of tap interface instead of something else defined by library. Cookie is passed to all subsequent function ops for any ip_addr, ip_route, ip_neigh and link updates. If application does not sets cookie, default value is DAO_NETLINK_APP_IF_COOKIE_INITIALIZER.

If "prefix_interface_name" is passed to dao_netlink_route_notifier_register() API, it looks for all LINUX interface names and if LINUX interface name has "prefix_interface_name" string in its name (eg: prefix_interface_name: "dtap" and LINUX interface name: dtap0, dtap1,...), get_app_interface_cookie() is called for each matched LINUX interface with

• Exact LINUX interface name
• LINUX notion of ifindex (See man page for if_nametoindex() information)

Application is supposed to set cookie value for any further function callbacks. Although linux_ifindex is also passed to all function callbacks for route, neigh, addr, and link updates

Parameters

	interface_name	LINUX interface name that matched with "prefix_interface_name" passed to dao_netlink_route_notifier_register()
	linux_ifindex	LINUX notion of ifindex. See if_nametoindex() library function
[out]	cookie	Application specific cookie for interface for any subsequent function calls

Returns

0: Succese <0: Failure

ip_local_addr_add_del

int(* ip_local_addr_add_del) (dao_netlink_route_ip_addr_t *dao_ip_addr, int is_add)

Add or delete Local IP address to interface.

Parameters

dao_ip_addr	See dao_netlink_route_ip_addr_t
is_add	Add addr if is_add == 1 else delete otherwise

Returns

0: Succese <0: Failure

Definition at line 311 of file dao_netlink_route.h.

ip_neigh_add_del

int(* ip_neigh_add_del) (dao_netlink_route_ip_neigh_t *dao_ip_neigh, int is_add)

Add or delete IP neighbor entry

Parameters

dao_ip_neigh	See dao_netlink_route_ip_neigh_t
is_add	Add neighbor if is_add == 1 else delete otherwise

Returns

0: Succese <0: Failure

Definition at line 325 of file dao_netlink_route.h.

link_add_del

int(* link_add_del) (dao_netlink_route_link_t *dao_link, int is_add)

Add or delete Link HW address

Parameters

dao_link	See dao_netlink_route_link_t
is_add	Add link if is_add == 1 else delete otherwise

Returns

0: Succese <0: Failure

Definition at line 339 of file dao_netlink_route.h.

ip_route_add_del

int(* ip_route_add_del) (dao_netlink_route_ip_route_t *dao_ip_route, dao_netlink_action_t action)

Add or delete IP route

Parameters

dao_ip_route	See dao_netlink_route_ip_route_t
action	Add, replace or delete based on action value

Returns

0: Succese <0: Failure
