Detailed Description

Function Documentation

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
skNetlink socket.
resultPointer 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.

+ Here is the call graph for this function:

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

Lookup neighbour table by name and optional interface index.

Parameters
cacheneighbour table cache
namename of table
ifindexoptional 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.

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
oldneighbour table to change
tmpltemplate with requested changes
resultPointer 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
skNetlink socket.
oldneighbour table to be changed
tmpltemplate 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
