Function Documentation

_radius_track_entry_release()

int _radius_track_entry_release	(	char const *	file,
		int	line,
		radius_track_entry_t **	te_to_free
	)

Release a tracking entry.

Parameters

[in]	file	Allocation was released in.
[in]	line	Allocation was released on.
[in,out]	te_to_free	The radius_track_entry_t allocated via radius_track_entry_reserve.

Returns

• <0 on error
• 0 on success

Definition at line 170 of file track.c.

Here is the call graph for this function:

_radius_track_entry_release_on_free()

static int _radius_track_entry_release_on_free ( radius_track_entry_t ***  te_p )

static

Ensures the entry is released when the ctx passed to radius_track_entry_reserve is freed.

Parameters

[in]

te_p

Entry to release.

Returns

0

Here is the caller graph for this function:

_radius_track_entry_reserve()

int _radius_track_entry_reserve	(	char const *	file,
		int	line,
		radius_track_entry_t **	te_out,
		TALLOC_CTX *	ctx,
		radius_track_t *	tt,
		request_t *	request,
		uint8_t	code,
		void *	uctx
	)

Allocate a tracking entry.

Parameters

[in]	file	The allocation was made in.
[in]	line	The allocation was made on.
[out]	te_out	Where the tracking entry should be written. If ctx is not-null, then this pointer must remain valid for the lifetime of the ctx.
[in]	ctx	If not-null, the tracking entry release will be bound to the lifetime of the talloc chunk.
[in]	tt	The radius_track_t tracking table.
[in]	request	The request which will send the proxied packet.
[in]	code	Of the outbound request.
[in]	uctx	The context to associate with the request

Returns

• 0 on success.
• -1 on failure.

Here is the call graph for this function:

radius_track_alloc()

radius_track_t * radius_track_alloc

(

TALLOC_CTX *

ctx

)

Create an radius_track_t.

Parameters

ctx	the talloc ctx

Returns

• NULL on error
• radius_track_t on success

	)

Find a tracking entry from a request authenticator.

Parameters

tt	The radius_track_t tracking table
packet_id	The ID from the RADIUS header
vector	The Request Authenticator (may be NULL)

Returns

• NULL on "not found"
• radius_track_entry_t on success

Parameters

te	The radius_track_entry_t, via radius_track_entry_reserve()
vector	The authentication vector for the packet we're sending

Returns

• <0 on error
• 0 on success
