Function Documentation

int iface_init	(	struct iface_t *	ifaces,
		int	epfd
	)

Create raw sockets for interfaces in a list and add them to an epoll instance.

Also set interface MAC if set-mac was specified in the config file.

Parameters

ifaces	Pointer to a list of struct iface_t structures representing network interfaces
epfd	File descriptor for an epoll instance

Returns

The number of interfaces added to epoll

int iface_count

(

struct iface_t *

ifaces

)

Count number of items in a list of struct iface_t.

Parameters

ifaces

Pointer to a list of struct iface_t structures representing network interfaces

Returns

The length of the list

void iface_reset_flags

(

struct iface_t *

iface

)

int iface_set_flags

(

struct iface_t *

iface

)

int iface_set_mac	(	struct iface_t *	iface,
		u_char *	src_mac
	)

Set the MAC address of a network interface.

Parameters

iface	Pointer to a struct iface_t representing an interface
src_mac	Pointer to ETH_ALEN bytes containing a MAC address

Returns

0 if successful, or -1 if unsuccessful

Note

Brings the interface down and back up, invalidating all sockets on it

char* iface_strmac

(

u_char *

mac

)

Convert a MAC address to a string.

Parameters

mac	Pointer to ETH_ALEN bytes containing a MAC address

Returns

Static buffer containing mac converted to a human-readable, colon-delimited MAC address
