struct nfct_timeout* nfct_timeout_alloc

(

void

)

nfct_timeout_alloc - allocate a new conntrack timeout object

Parameters

protonum

layer 4 protocol number (use IPPROTO_* constants)

You can use IPPROTO_MAX to set the timeout for the generic protocol tracker.

In case of success, this function returns a valid pointer, otherwise NULL s returned and errno is appropriately set.

References NULL.

int nfct_timeout_attr_set	(	struct nfct_timeout *	t,
		uint32_t	type,
		const void *	data
	)

nfct_timeout_attr_set - set one attribute of the conntrack timeout object

Parameters

t	pointer to the conntrack timeout object
type	attribute type you want to set
data	pointer to data that will be used to set this attribute

	)

nfct_timeout_attr_unset - unset one attribute of the conntrack timeout object

Parameters

t	pointer to the conntrack timeout object
type	attribute type you want to set

void nfct_timeout_free

(

struct nfct_timeout *

t

)

nfct_timeout_free - release one conntrack timeout object

Parameters

t	pointer to the conntrack timeout object

References nfct_timeout::timeout.

int nfct_timeout_policy_attr_set_u32	(	struct nfct_timeout *	t,
		uint32_t	type,
		uint32_t	data
	)

nfct_timeout_policy_attr_set_u32 - set one attribute of the policy

Parameters

t	pointer to the conntrack timeout object
type	attribute type you want to set
data	data that will be used to set this attribute

const char* nfct_timeout_policy_attr_to_name	(	uint8_t	l4proto,
		uint32_t	state
	)

nfct_timeout_policy_attr_to_name - get state name from protocol state number

Parameters

l4proto	protocol, ie. IPPROTO_*
state	state number that you want to get the state name

This function returns NULL if unsupported protocol or state number is passed. Otherwise, a pointer to valid string is returned.

void nfct_timeout_policy_attr_unset	(	struct nfct_timeout *	t,
		uint32_t	type
	)

nfct_timeout_policy_attr_unset - unset one attribute of the policy

Parameters

t	pointer to the conntrack timeout object
type	attribute type you want to set
