1199 /*** Plugin framework ***/
1202 * This framework can be used to create pluggable interfaces. Not all existing
1203 * pluggable interface use this framework, but new ones should. A new
1204 * pluggable interface entails:
1206 * - An interface ID definition in the list of #defines below.
1208 * - A name in the interface_names array in lib/krb5/krb/plugins.c.
1210 * - An installed public header file in include/krb5. The public header should
1211 * include <krb5/plugin.h> and should declare a vtable structure for each
1212 * supported major version of the interface.
1214 * - A consumer API implementation, located within the code unit which makes
1215 * use of the pluggable interface. The consumer API should consist of:
1217 * . An interface-specific handle type which contains a vtable structure for
1218 * the module (or a union of several such structures, if there are multiple
1219 * supported major versions) and, optionally, resource data bound to the
1222 * . An interface-specific loader function which creates a handle or list of
1223 * handles. A list of handles would be created if the interface is a
1224 * one-to-many interface where the consumer wants to consult all available
1225 * modules; a single handle would be created for an interface where the
1226 * consumer wants to consult a specific module. The loader function should
1227 * use k5_plugin_load or k5_plugin_load_all to produce one or a list of
1228 * vtable initializer functions, and should use those functions to fill in
1229 * the vtable structure for the module (if necessary, trying each supported
1230 * major version starting from the most recent). The loader function can
1231 * also bind resource data into the handle based on caller arguments, if
1234 * . For each plugin method, a wrapper function which accepts a krb5_context,
1235 * a plugin handle, and the method arguments. Wrapper functions should
1236 * invoke the method function contained in the handle's vtable.
1238 * - Possibly, built-in implementations of the interface, also located within
1239 * the code unit which makes use of the interface. Built-in implementations
1240 * must be registered with k5_plugin_register before the first call to
1241 * k5_plugin_load or k5_plugin_load_all.
1243 * A pluggable interface should have one or more currently supported major
1244 * versions, starting at 1. Each major version should have a current minor
1245 * version, also starting at 1. If new methods are added to a vtable, the
1246 * minor version should be incremented and the vtable stucture should document
1247 * where each minor vtable version ends. If method signatures for a vtable are
1248 * changed, the major version should be incremented.
1250 * Plugin module implementations (either built-in or dynamically loaded) should
1251 * define a function named <interfacename>_<modulename>_initvt, matching the
1252 * signature of krb5_plugin_initvt_fn as declared in include/krb5/plugin.h.
1253 * The initvt function should check the given maj_ver argument against its own
1254 * supported major versions, cast the vtable pointer to the appropriate
1255 * interface-specific vtable type, and fill in the vtable methods, stopping as
1256 * appropriate for the given min_ver. Memory for the vtable structure is
1257 * allocated by the caller, not by the module.
1259 * Dynamic plugin modules are registered with the framework through the
1260 * [plugins] section of the profile, as described in the admin documentation
1261 * and krb5.conf man page.
1265 * A linked list entry mapping a module name to a module initvt function. The
1266 * entry may also include a dynamic object handle so that it can be released
1267 * when the context is destroyed.
