Function Documentation

◆ conf_file_subparse()

isc_result_t conf_file_subparse ( struct parse *  cfile,
struct group *  group,
int  group_type 
)

Definition at line 250 of file confpars.c.

◆ get_permit()

void get_permit ( struct parse *  cfile,
struct permit **  permit_head,
int  is_allow,
TIME *  valid_from,
TIME *  valid_until 
)

Parse allow and deny statements.

This function handles the common processing code for permit and deny statements in the parse_pool_statement and parse_pool6_statement functions. It reads in the configuration and constructs a new permit structure that it attachs to the permit_head passed in from the caller.

The allow or deny token should already be consumed, this function expects one of the following: known-clients; unknown-clients; known clients; unknown clients; authenticated clients; unauthenticated clients; all clients; dynamic bootp clients; members of <class name>="">; after <date>;

Parameters
[in]cfile= the configuration file being parsed
[in]permit_head= the head of the permit list (permit or prohibit) to which to attach the newly created permit structure
[in]is_allow= 1 if this is being invoked for an allow statement = 0 if this is being invoked for a deny statement
[in]valid_from= pointers to the time values from the enclosing pool
[in]valid_untilor pond structure. One of them will be filled in if the configuration includes an "after" clause

◆ parse_pool_statement()

void parse_pool_statement ( struct parse *  cfile,
struct group *  group,
int  type 
)

Parse a pool statement.

Pool statements are used to group declarations and permit & deny information with a specific address range. They must be declared within a shared network or subnet and there may be multiple pools withing a shared network or subnet. Each pool may have a different set of permit or deny options.

Parameters
[in]cfile= the configuration file being parsed
[in]group= the group structure for this pool
[in]type= the type of the enclosing statement. This must be SHARED_NET_DECL or SUBNET_DECL for this function.
Returns
void - This function either parses the statement and updates the structures or it generates an error message and possible halts the program if it encounters a problem.
