Definition at line 363 of file neightbl.c.

◆ rtnl_neightbl_put()

void rtnl_neightbl_put ( struct rtnl_neightbl * neightbl )

Definition at line 368 of file neightbl.c.

◆ rtnl_neightbl_alloc_cache()

int rtnl_neightbl_alloc_cache	(	struct nl_sock *	sk,
		struct nl_cache **	result
	)

Build a neighbour table cache including all neighbour tables currently configured in the kernel.

Parameters

sk	Netlink socket.
result	Pointer to store resulting cache.

Allocates a new neighbour table cache, initializes it properly and updates it to include all neighbour tables currently configured in the kernel.

Returns: 0 on success or a negative error code.

◆ rtnl_neightbl_get()

struct rtnl_neightbl * rtnl_neightbl_get	(	struct nl_cache *	cache,
		const char *	name,
		int	ifindex
	)

Lookup neighbour table by name and optional interface index.

Parameters

cache	neighbour table cache
name	name of table
ifindex	optional interface index

Looks up the neighbour table matching the specified name and optionally the specified ifindex to retrieve device specific parameter sets.

Returns: ptr to neighbour table inside the cache or NULL if no match was found.

◆ rtnl_neightbl_build_change_request()

int rtnl_neightbl_build_change_request	(	struct rtnl_neightbl *	old,
		struct rtnl_neightbl *	tmpl,
		struct nl_msg **	result
	)

Builds a netlink change request message to change neighbour table attributes.

Parameters

old	neighbour table to change
tmpl	template with requested changes
result	Pointer to store resulting message.

Builds a new netlink message requesting a change of neighbour table attributes. The netlink message header isn't fully equipped with all relevant fields and must be sent out via nl_send_auto_complete() or supplemented as needed. old must point to a neighbour table currently configured in the kernel and tmpl must contain the attributes to be changed set via rtnl_neightbl_set_* functions.

Returns: 0 on success or a negative error code.

int rtnl_neightbl_change	(	struct nl_sock *	sk,
		struct rtnl_neightbl *	old,
		struct rtnl_neightbl *	tmpl
	)

Change neighbour table attributes.

Parameters

sk	Netlink socket.
old	neighbour table to be changed
tmpl	template with requested changes

Builds a new netlink message by calling rtnl_neightbl_build_change_request(), sends the request to the kernel and waits for the next ACK to be received, i.e. blocks until the request has been processed.

Returns: 0 on success or a negative error code
