Function Documentation

bool client_add ( RADCLIENT_LIST *  clients,
RADCLIENT *  client 
)

Add a client to a RADCLIENT_LIST.

Parameters
clientslist to add client to, may be NULL if global client list is being used.
clientto add.
Returns
  • true on success.
  • false on failure.

RADCLIENT* client_afrom_cs ( TALLOC_CTX *  ctx,

)

Allocate a new client from a config section.

Parameters
ctxto allocate new clients in.
csto process as a client.
in_serverWhether the client should belong to a specific virtual server.
with_coaIf true and coa_server or coa_pool aren't specified automatically, create a coa home_server section and add it to the client CONF_SECTION.
Returns
new RADCLIENT struct.

)

Add a client from a result set (SQL)

Todo:

identifierClient IP Address / IPv4 subnet / IPv6 subnet / FQDN.
secretClient secret.
shortnameClient friendly name.
typeNAS-Type.
serverVirtual-Server to associate clients with.
require_maIf true all packets from client must include a message-authenticator.
Returns
  • New client.
  • NULL on error.

+ Here is the call graph for this function:

int client_map_section ( CONF_SECTION *  out,
CONF_SECTION const *  map,
client_value_cb_t  func,
void *  data 
)

Create a client CONF_SECTION using a mapping section to map values from a result set to client attributes.

If we hit a CONF_SECTION we recurse and process its CONF_PAIRS too.

Note
Caller should free CONF_SECTION passed in as out, on error. Contents of that section will be in an undefined state.
Parameters
[in,out]outSection to perform mapping on. Either the root of the client config, or a parent section (when this function is called recursively). Should be alloced with cf_section_alloc, or if there's a separate template section, the result of calling cf_section_dup on that section.
[in]mapsection.
[in]functo call to retrieve CONF_PAIR values. Must return a talloced buffer containing the value.
[in]datato pass to func, usually a result pointer.
Returns
  • 0 on success.
  • -1 on failure.
