list_mod_alloc()

static vp_list_mod_t* list_mod_alloc ( TALLOC_CTX *  ctx )

inlinestatic

Definition at line 45 of file map_async.c.

Here is the caller graph for this function:

list_mod_delete_afrom_map()

static vp_list_mod_t* list_mod_delete_afrom_map ( TALLOC_CTX *  ctx, map_t const *  original, map_t const *  mutated  )

inlinestatic

Allocate a 'delete' vp_list_mod_t.

This will cause the dst (LHS) to be deleted when applied. This is intended to be used where the RHS expansion is NULL, and we're doing a := assignment, so need to delete the LHS.

Parameters

[in]	ctx	to allocate vp_list_mod_t in.
[in]	original	The map from the update section.
[in]	mutated	The original map but with a altered dst (LHS). If the LHS of the original map was not expanded, this should be the same as original.

Returns

• A new vlm structure on success.
• NULL on failure.

Definition at line 116 of file map_async.c.

Here is the call graph for this function:

list_mod_empty_string_afrom_map()

static vp_list_mod_t* list_mod_empty_string_afrom_map ( TALLOC_CTX *  ctx, map_t const *  original, map_t const *  mutated  )

inlinestatic

Allocate an 'empty_string' vp_list_mod_t.

This shallow copies the mutated map, but sets the RHS to be an empty string.

Parameters

[in]	ctx	to allocate vp_list_mod_t in.
[in]	original	The map from the update section.
[in]	mutated	The original map but with a altered dst (LHS). If the LHS of the original map was not expanded, this should be the same as original.

Returns

• A new vlm structure on success.
• NULL on failure.

Here is the call graph for this function:

list_mod_generic_afrom_map()

static vp_list_mod_t* list_mod_generic_afrom_map ( TALLOC_CTX *  ctx, map_t const *  original, map_t const *  mutated  )

inlinestatic

Allocate a 'generic' vp_list_mod_t.

This covers most cases, where we need to allocate a vp_list_mod_t with a single modification map, with an attribute ref LHS, and a boxed value RHS.

Parameters

[in]	ctx	to allocate vp_list_mod_t in.
[in]	original	The map from the update section.
[in]	mutated	The original map but with a altered dst (LHS). If the LHS of the original map was not expanded, this should be the same as original.

Returns

• A new vlm structure on success.
• NULL on failure.

map_check_src_or_dst()

static fr_pair_list_t* map_check_src_or_dst ( request_t *  request, map_t const *  map, tmpl_t const *  src_dst  )

inlinestatic

Check that the destination list is currently value.

Parameters

[in]	request	to resolve in the list in.
[in]	map	to check
[in]	src_dst	a lhs or rhs tmpl to check.

Returns

• destination list if list is valid.
• NULL if destination list is invalid.

Here is the call graph for this function:

map_list_mod_apply()

int map_list_mod_apply	(	request_t *	request,
		vp_list_mod_t const *	vlm
	)

Apply the output of map_to_list_mod to a request.

Parameters

request	to modify.
vlm	VP List Modification to apply.

map_list_mod_debug()

static void map_list_mod_debug ( request_t *  request, map_t const *  map, map_t const *  mod, fr_value_box_t const *  vb  )

inlinestatic

Print debug for a modification map.

Parameters

[in]	request	being modified.
[in]	map	The original map.
[in]	mod	The ephemeral map which describes the change.
[in]	vb	The value in the ephemeral map.

map_list_mod_to_vps()

static

Allocate one or more fr_pair_ts from a vp_list_mod_t.

Here is the caller graph for this function:

map_to_list_mod()

int map_to_list_mod	(	TALLOC_CTX *	ctx,
		vp_list_mod_t **	out,
		request_t *	request,
		map_t const *	original,
		fr_value_box_list_t *	lhs_result,
		fr_value_box_list_t *	rhs_result
	)

Evaluate a map creating a new map with TMPL_TYPE_ATTR LHS and TMPL_TYPE_DATA RHS.

This function creates maps for consumption by map_to_request.

Parameters

[in,out]	ctx	to allocate modification maps in.
[out]	out	Where to write the fr_pair_t (s), which may be NULL if not found
[in]	request	The current request.
[in]	original	the map. The LHS (dst) has to be TMPL_TYPE_ATTR.
[in]	lhs_result	of previous stack based rhs evaluation. Must be provided for rhs types: TMPL_TYPE_XLAT TMPL_TYPE_EXEC (in future)
[in]	rhs_result	of previous stack based rhs evaluation. Must be provided for rhs types: TMPL_TYPE_XLAT TMPL_TYPE_EXEC (in future) Once this function returns result will be invalidated even if this function errors.

Returns

• 0 on success.
• -1 on failure.
