Data Structure Documentation

◆ dict_attr_args_t

struct dict_attr_args_t

Optional arguments for initialising/allocating attributes.

Definition at line 209 of file dict_priv.h.

Collaboration diagram for dict_attr_args_t:

Data Fields
fr_dict_attr_flags_t const *	flags	Any flags to assign to the attribute.
fr_dict_attr_t const *	ref	This attribute is a reference to another attribute.

◆ fr_dict_dependent_t

struct fr_dict_dependent_t

Entry recording dictionary reference holders by file.

Definition at line 58 of file dict_priv.h.

Collaboration diagram for fr_dict_dependent_t:

Data Fields
int	count	How many references are held by this file. Signed to help figure out when things go wrong...
char const *	dependent	File holding the reference.
fr_rb_node_t	node

◆ fr_dict_filename_src_t

struct fr_dict_filename_src_t

One load or $INCLUDE of a dictionary file.

Definition at line 68 of file dict_priv.h.

Collaboration diagram for fr_dict_filename_src_t:

Data Fields
fr_dlist_t	entry	Entry in the file's list of sources.
char const *	src_file	File which did the $INCLUDE. NULL for a top-level load.
int	src_line	Line of the $INCLUDE in src_file.

◆ fr_dict_filename_t

struct fr_dict_filename_t

Entry in the table of files associated with this dictionary.

Mainly used for debugging.

Definition at line 80 of file dict_priv.h.

Collaboration diagram for fr_dict_filename_t:

Data Fields
char *	filename	Name of the file the dictionary was loaded from.
uint16_t	id	Ordinal of this file within the dictionary. fr_dict_attr_t stores the id instead of a pointer, which keeps the attribute struct within one cache line. Id 0 is reserved for "no location recorded".
fr_dlist_head_t	sources	Each load or $INCLUDE of the file.

◆ fr_dict_gctx_s

struct fr_dict_gctx_s

Definition at line 146 of file dict_priv.h.

Collaboration diagram for fr_dict_gctx_s:

Data Fields
fr_dict_attr_t const *	attr_protocol_encapsulation
char *	dict_dir_default	The default location for loading dictionaries if one wasn't provided.
dl_loader_t *	dict_loader	for protocol validation
bool	free_at_exit	This gctx will be freed on exit.
fr_dict_t *	internal	Magic internal dictionary. Internal dictionary is checked in addition to the protocol dictionary when resolving attribute names. This is because internal attributes are valid for every protocol.

fr_hash_table_t *	protocol_by_name	Hash containing names of all the registered protocols.
fr_hash_table_t *	protocol_by_num	Hash containing numbers of all the registered protocols.
bool	read_only

◆ fr_dict_s

struct fr_dict_s

Vendors and attribute names.

It's very likely that the same vendors will operate in multiple protocol spaces, but number their attributes differently, so we need per protocol dictionaries.

There would also be conflicts for DHCP(v6)/RADIUS attributes etc...

		fr_dict_attr_t const *	parent,
		char const *	name,
		int	attr,
		fr_type_t	type,
		dict_attr_args_t const *	args
	)

Allocate a dictionary attribute on the heap.

Parameters

[in]	filename	file.
[in]	line	number.
[in]	ctx	to allocate the attribute in.
[in]	parent	of the attribute.
[in]	name	of the attribute. If NULL an OID string will be created and set as the name.

[in]	args	optional initialisation arguments.

Returns

A new fr_dict_attr_t on success.
NULL on failure.

Parameters

[in]	filename	file.
[in]	line	number.
[in]	ctx	to allocate the attribute in.

		char const *	name,
		unsigned int	attr,
		fr_type_t	type,
		dict_attr_args_t const *	args
	)

Initialise fields in a dictionary attribute structure.

This function is a wrapper around the other initialisation functions.

The reason for the separation, is that sometimes we're initialising a dictionary attribute by parsing an actual dictionary file, and other times we're copying attribute, or initialising them programatically.

This function should only be used for the second case, where we have a complet attribute definition already.

Note: This function can only be used before the attribute is inserted into the dictionary.

Parameters

[in]	filename	file.
[in]	line	number.
[in]	da_p	to initialise.
[in]	parent	of the attribute, if none, this attribute will be initialised as a dictionary root.
[in]	name	of attribute. Pass NULL for auto-generated name.
[in]	attr	number.
[in]	type	of the attribute.
[in]	args	optional initialisation arguments.

Returns

0 on success.
<0 on error.

fr_dict_attr_t * dict_attr_alloc_null	(	TALLOC_CTX *	ctx,

Partial initialisation functions.

These functions are used to initialise attributes in stages, i.e. when parsing a dictionary.

The finalise function must be called to complete the initialisation.

All functions must be called to fully initialise a dictionary attribute, except dict_attr_parent_init this is not necessary for root attributes.

Partial initialisation functions.

This is useful in some instances where we need to pre-allocate the attribute for talloc hierarchy reasons, but want to finish initialising it with dict_attr_init later.

Parameters

[in]	ctx	to allocate attribute in.
[in]	proto	protocol specific extensions.

Returns

A new, partially completed, fr_dict_attr_t on success.
NULL on failure (memory allocation error).
