/*! \defgroup pjsip_threading PJSIP Threading Model
 * @{
 * \page PJSIP PJSIP Threading Model
 *
 * There are three major types of threads that SIP will have to deal with:
 * \li Asterisk threads
 * \li PJSIP threads
 * \li SIP taskpool threads (a.k.a. "servants")
 *
 * \par Asterisk Threads
 *
 * Asterisk threads are those that originate from outside of SIP but within
 * Asterisk. The most common of these threads are PBX (channel) threads and
 * the autoservice thread. Most interaction with these threads will be through
 * channel technology callbacks. Within these threads, it is fine to handle
 * Asterisk data from outside of SIP, but any handling of SIP data should be
 * left to servants, \b especially if you wish to call into PJSIP for anything.
 * Asterisk threads are not registered with PJLIB, so attempting to call into
 * PJSIP will cause an assertion to be triggered, thus causing the program to
 * crash.
 *
 * \par PJSIP Threads
 *
 * PJSIP threads are those that originate from handling of PJSIP events, such
 * as an incoming SIP request or response, or a transaction timeout. The role
 * of these threads is to process information as quickly as possible so that
 * the next item on the SIP socket(s) can be serviced. On incoming messages,
 * Asterisk automatically will push the request to a servant thread. When your
 * module callback is called, processing will already be in a servant. However,
 * for other PJSIP events, such as transaction state changes due to timer
 * expirations, your module will be called into from a PJSIP thread. If you
 * are called into from a PJSIP thread, then you should push whatever processing
 * is needed to a servant as soon as possible. You can discern if you are currently
 * in a SIP servant thread using the \ref ast_sip_thread_is_servant function.
 *
 * \par Servants
 *
 * Servants are where the bulk of SIP work should be performed. These threads
 * exist in order to do the work that Asterisk threads and PJSIP threads hand
 * off to them. Servant threads register themselves with PJLIB, meaning that
 * they are capable of calling PJSIP and PJLIB functions if they wish.
 *
 * \par Serializer
 *
 * Tasks are handed off to servant threads using the API call \ref ast_sip_push_task.
 * The first parameter of this call is a serializer. If this pointer
 * is NULL, then the work will be handed off to whatever servant can currently handle
 * the task. If this pointer is non-NULL, then the task will not be executed until
 * previous tasks pushed with the same serializer have completed. For more information
 * on serializers and the benefits they provide, see \ref ast_taskpool_serializer
 *
 * \par Scheduler
 *
 * Some situations require that a task run periodically or at a future time.  Normally
 * the ast_sched functionality would be used but ast_sched only uses 1 thread for all
 * tasks and that thread isn't registered with PJLIB and therefore can't do any PJSIP
 * related work.
 *
 * ast_sip_sched uses ast_sched only as a scheduled queue.  When a task is ready to run,
 * it's pushed to a Serializer to be invoked asynchronously by a Servant.  This ensures
 * that the task is executed in a PJLIB registered thread and allows the ast_sched thread
 * to immediately continue processing the queue.  The Serializer used by ast_sip_sched
 * is one of your choosing or a random one from the res_pjsip pool if you don't choose one.
 *
 * \note
 *
 * Do not make assumptions about individual threads based on a corresponding serializer.
 * In other words, just because several tasks use the same serializer when being pushed
 * to servants, it does not mean that the same thread is necessarily going to execute those
 * tasks, even though they are all guaranteed to be executed in sequence.

 * specific interval.  That is, every \p interval milliseconds, regardless of how long the task
 * takes. If the task takes longer than \p interval, it will be scheduled at the next available
 * multiple of \p interval.  For example: If the task has an interval of 60 seconds and the task
 * takes 70 seconds, the next invocation will happen at 120 seconds.
 *
 * \ref AST_SIP_SCHED_TASK_DELAY specifies that the next invocation of the task should start

 * \brief General purpose method for creating a UAS dialog with an endpoint
 *
 * This function creates and returns a locked, and referenced counted pjsip
 * dialog object. The caller is thus responsible for freeing the allocated
 * memory, decrementing the reference, and releasing the lock when done with
 * the returned object.
 *
 * \note The safest way to unlock the object, and decrement its reference is by
 *       calling pjsip_dlg_dec_lock. Alternatively, pjsip_dlg_dec_session can be
 *       used to decrement the reference only.
 *
 * The dialog is returned locked and with a reference in order to ensure that the
 * dialog object, and any of its associated objects (e.g. transaction) are not
 * untimely destroyed. For instance, that could happen when a transport error
 * occurs.
 *
 * As long as the caller maintains a reference to the dialog there should be no
 * worry that it might unknowingly be destroyed. However, once the caller unlocks
 * the dialog there is a danger that some of the dialog's internal objects could
 * be lost and/or compromised. For example, when the aforementioned transport error
 * occurs the dialog's associated transaction gets destroyed (see pjsip_dlg_on_tsx_state
 * in sip_dialog.c, and mod_inv_on_tsx_state in sip_inv.c).
 *
 * In this case and before using the dialog again the caller should re-lock the
 * dialog, check to make sure the dialog is still established, and the transaction
 * still exists and has not been destroyed.
 *
 * \param endpoint A pointer to the endpoint
 * \param rdata The request that is starting the dialog

 *
 * This URI is used as the Request URI.
 *
 * Expects the given 'to' to be in one of the following formats:
 * Why we allow so many is a mystery.
 *
 * Basic:
 *
 *      endpoint        : We'll get URI from the default aor/contact
 *      endpoint/aor    : We'll get the URI from the specific aor/contact
 *      endpoint@domain : We toss the domain part and just use the endpoint
 *
 *   These all use the endpoint and specified URI:
 * \verbatim
        endpoint/<sip[s]:host>
        endpoint/<sip[s]:user@host>
        endpoint/"Bob" <sip[s]:host>
        endpoint/"Bob" <sip[s]:user@host>
        endpoint/sip[s]:host
        endpoint/sip[s]:user@host
        endpoint/host
        endpoint/user@host
   \endverbatim
 *
 *   These all use the default endpoint and specified URI:
 * \verbatim
        <sip[s]:host>
        <sip[s]:user@host>
        "Bob" <sip[s]:host>
        "Bob" <sip[s]:user@host>
        sip[s]:host
        sip[s]:user@host
   \endverbatim
 *
 *   These use the default endpoint and specified host:
 * \verbatim
        host
        user@host
   \endverbatim
 *
 *   This form is similar to a dialstring:
 * \verbatim
        PJSIP/user@endpoint
   \endverbatim
 *
 *   In this case, the user will be added to the endpoint contact's URI.
 *   If the contact URI already has a user, it will be replaced.
 *
 * The ones that have the sip[s] scheme are the easiest to parse.
 * The rest all have some issue.
 *
 *      endpoint vs host              : We have to test for endpoint first
 *      endpoint/aor vs endpoint/host : We have to test for aor first
 *                                      What if there's an aor with the same
 *                                      name as the host?
 *      endpoint@domain vs user@host  : We have to test for endpoint first.
 *                                      What if there's an endpoint with the

ast_sip_dialog_outbound_auth_cb

typedef int(* ast_sip_dialog_outbound_auth_cb) (pjsip_dialog *dlg, pjsip_tx_data *tdata, void *user_data)

Callback called when an outbound request with authentication credentials is to be sent in dialog.

This callback will have the created request on it. The callback's purpose is to do any extra housekeeping that needs to be done as well as to send the request out.

This callback is only necessary if working with a PJSIP API that sits between the application and the dialog layer.

Parameters

dlg	The dialog to which the request belongs
tdata	The created request to be sent out
user_data	Data supplied with the callback

Return values

0	Success
-1	Failure

Function Documentation

ast_copy_pj_str()

void ast_copy_pj_str	(	char *	dest,
		const pj_str_t *	src,
		size_t	size
	)

Copy a pj_str_t into a standard character buffer.

pj_str_t is not NULL-terminated. Any place that expects a NULL- terminated string needs to have the pj_str_t copied into a separate buffer.

This method copies the pj_str_t contents into the destination buffer and NULL-terminates the buffer.

Parameters

dest	The destination buffer
src	The pj_str_t to copy
size	The size of the destination buffer.

Definition at line 2172 of file res_pjsip.c.

{
    size_t chars_to_copy = MIN(size - 1, pj_strlen(src));
    memcpy(dest, pj_strbuf(src), chars_to_copy);
    dest[chars_to_copy] = '\0';
}

ast_copy_pj_str2()

int ast_copy_pj_str2	(	char **	dest,
		const pj_str_t *	src
	)

Create and copy a pj_str_t into a standard character buffer.

pj_str_t is not NULL-terminated. Any place that expects a NULL- terminated string needs to have the pj_str_t copied into a separate buffer.

Copies the pj_str_t contents into a newly allocated buffer pointed to by dest. NULL-terminates the buffer.

Note

Caller is responsible for freeing the allocated memory.

Parameters

[out]	dest	The destination buffer
	src	The pj_str_t to copy

Returns

Number of characters copied or negative value on error

ast_pjsip_rdata_get_endpoint()

struct ast_sip_endpoint * ast_pjsip_rdata_get_endpoint

(

pjsip_rx_data *

rdata

)

Get the looked-up endpoint on an out-of dialog request or response.

The function may ONLY be called on out-of-dialog requests or responses. For in-dialog requests and responses, it is required that the user of the dialog has the looked-up endpoint stored locally.

This function should never return NULL if the message is out-of-dialog. It will always return NULL if the message is in-dialog.

This function will increase the reference count of the returned endpoint by one. Release your reference using the ao2_ref function when finished.

Parameters

rdata

Out-of-dialog request or response

Returns

The looked up endpoint

Method to determine authentication status of an incoming request.

This will call into a registered authenticator. The registered authenticator will do what is necessary to determine whether the incoming request passes authentication. A tentative response is passed into this function so that if, say, a digest authentication challenge should be sent in the ensuing response, it can be added to the response.

Parameters

rdata	The request to potentially authenticate
tdata	Tentative response to the request

Returns

The result of checking authentication.

pjsip_dialog * ast_sip_create_dialog_uas	(	const struct ast_sip_endpoint *	endpoint,
		pjsip_rx_data *	rdata,
		pj_status_t *	status
	)

General purpose method for creating a UAS dialog with an endpoint.

Deprecated:

This function is unsafe (due to the returned object not being locked nor having its reference incremented) and should no longer be used. Instead use ast_sip_create_dialog_uas_locked so a properly locked and referenced object is returned.

Parameters

	endpoint	A pointer to the endpoint
	rdata	The request that is starting the dialog
[out]	status	On failure, the reason for failure in creating the dialog

ast_sip_create_dialog_uas_locked()

pjsip_dialog * ast_sip_create_dialog_uas_locked	(	const struct ast_sip_endpoint *	endpoint,
		pjsip_rx_data *	rdata,
		pj_status_t *	status
	)

General purpose method for creating a UAS dialog with an endpoint.

This function creates and returns a locked, and referenced counted pjsip dialog object. The caller is thus responsible for freeing the allocated memory, decrementing the reference, and releasing the lock when done with the returned object.

Note

The safest way to unlock the object, and decrement its reference is by calling pjsip_dlg_dec_lock. Alternatively, pjsip_dlg_dec_session can be used to decrement the reference only.

The dialog is returned locked and with a reference in order to ensure that the dialog object, and any of its associated objects (e.g. transaction) are not untimely destroyed. For instance, that could happen when a transport error occurs.

As long as the caller maintains a reference to the dialog there should be no worry that it might unknowingly be destroyed. However, once the caller unlocks the dialog there is a danger that some of the dialog's internal objects could be lost and/or compromised. For example, when the aforementioned transport error occurs the dialog's associated transaction gets destroyed (see pjsip_dlg_on_tsx_state in sip_dialog.c, and mod_inv_on_tsx_state in sip_inv.c).

In this case and before using the dialog again the caller should re-lock the dialog, check to make sure the dialog is still established, and the transaction still exists and has not been destroyed.

Parameters

	endpoint	A pointer to the endpoint
	rdata	The request that is starting the dialog
[out]	status	On failure, the reason for failure in creating the dialog

Return values

A	locked, and reference counted pjsip_dialog object.
NULL	on failure

ast_sip_create_request()

int ast_sip_create_request	(	const char *	method,
		struct pjsip_dialog *	dlg,
		struct ast_sip_endpoint *	endpoint,
		const char *	uri,
		struct ast_sip_contact *	contact,
		pjsip_tx_data **	tdata
	)

General purpose method for creating a SIP request.

Its typical use would be to create one-off requests such as an out of dialog SIP MESSAGE.

The request can either be in- or out-of-dialog. If in-dialog, the dlg parameter MUST be present. If out-of-dialog the endpoint parameter MUST be present. If both are present, then we will assume that the message is to be sent in-dialog.

The uri parameter can be specified if the request should be sent to an explicit URI rather than one configured on the endpoint.

Parameters

	method	The method of the SIP request to send
	dlg	Optional. If specified, the dialog on which to request the message.
	endpoint	Optional. If specified, the request will be created out-of-dialog to the endpoint.
	uri	Optional. If specified, the request will be sent to this URI rather than one configured for the endpoint.
	contact	The contact with which this request is associated for out-of-dialog requests.
[out]	tdata	The newly-created request

The provided contact is attached to tdata with its reference bumped, but will not survive for the entire lifetime of tdata since the contact is cleaned up when all supplements have completed execution.

Return values

0	Success
-1	Failure

ast_sip_get_endpoint()

struct ast_sip_endpoint * ast_sip_get_endpoint	(	const char *	to,
		int	get_default_outbound,
		char **	uri
	)

Retrieves an endpoint and URI from the "to" string.

This URI is used as the Request URI.

Expects the given 'to' to be in one of the following formats: Why we allow so many is a mystery.

Basic:

 endpoint        : We'll get URI from the default aor/contact
 endpoint/aor    : We'll get the URI from the specific aor/contact
 endpoint@domain : We toss the domain part and just use the endpoint

These all use the endpoint and specified URI:

     endpoint/<sip[s]:host>
     endpoint/<sip[s]:user@host>
     endpoint/"Bob" <sip[s]:host>
     endpoint/"Bob" <sip[s]:user@host>
     endpoint/sip[s]:host
     endpoint/sip[s]:user@host
     endpoint/host
     endpoint/user@host

These all use the default endpoint and specified URI:

     <sip[s]:host>
     <sip[s]:user@host>
     "Bob" <sip[s]:host>
     "Bob" <sip[s]:user@host>
     sip[s]:host
     sip[s]:user@host

These use the default endpoint and specified host:

     host
     user@host

This form is similar to a dialstring:

     PJSIP/user@endpoint

In this case, the user will be added to the endpoint contact's URI. If the contact URI already has a user, it will be replaced.

The ones that have the sip[s] scheme are the easiest to parse. The rest all have some issue.

 endpoint vs host              : We have to test for endpoint first
 endpoint/aor vs endpoint/host : We have to test for aor first
                                 What if there's an aor with the same
                                 name as the host?
 endpoint@domain vs user@host  : We have to test for endpoint first.
                                 What if there's an endpoint with the
                                 same name as the user?

Parameters

to	'To' field with possible endpoint
get_default_outbound	If nonzero, try to retrieve the default outbound endpoint if no endpoint was found. Otherwise, return NULL if no endpoint was found.
uri	Pointer to a char* which will be set to the URI. Always must be ast_free'd by the caller - even if the return value is NULL!

The logic below could probably be condensed but then it wouldn't be as clear.

ast_sip_register_endpoint_identifier()

int ast_sip_register_endpoint_identifier

(

struct ast_sip_endpoint_identifier *

identifier

)

Register a SIP endpoint identifier.

An endpoint identifier's purpose is to determine which endpoint a given SIP message has come from.

Multiple endpoint identifiers may be registered so that if an endpoint cannot be identified by one identifier, it may be identified by another.

Asterisk provides two endpoint identifiers. One identifies endpoints based on the user part of the From header URI. The other identifies endpoints based on the source IP address.

If the order in which endpoint identifiers is run is important to you, then be sure to load individual endpoint identifier modules in the order you wish for them to be run in modules.conf

Note

endpoint identifiers registered using this method (no name specified) are placed at the front of the endpoint identifiers list ahead of any named identifiers.

Parameters

identifier

The SIP endpoint identifier to register

Return values

0	Success
-1	Failure

ast_sip_register_outbound_authenticator()

int ast_sip_register_outbound_authenticator

(

struct ast_sip_outbound_authenticator *

outbound_auth

)

Register an outbound SIP authenticator.

An outbound authenticator is responsible for creating responses to authentication challenges by remote endpoints.

Parameters

outbound_auth

The authenticator to register

Return values

0	Success
-1	Failure

Definition at line 185 of file res_pjsip.c.

ast_sip_register_service()

int ast_sip_register_service

(

pjsip_module *

module

)

Register a SIP service in Asterisk.

This is more-or-less a wrapper around pjsip_endpt_register_module(). Registering a service makes it so that PJSIP will call into the service at appropriate times. For more information about PJSIP module callbacks, see the PJSIP documentation. Asterisk modules that call this function will likely do so at module load time.

Parameters

module

The module that is to be registered with PJSIP

Return values

0	Success
-1	Failure

ast_sip_register_supplement()

void ast_sip_register_supplement

(

struct ast_sip_supplement *

supplement

)

Register a supplement to SIP out of dialog processing.

This allows for someone to insert themselves in the processing of out of dialog SIP requests and responses. This, for example could allow for a module to set channel data based on headers in an incoming message. Similarly, a module could reject an incoming request if desired.

Parameters

supplement

The supplement to register

ast_sip_retrieve_auths_vector()

int ast_sip_retrieve_auths_vector	(	const struct ast_sip_auth_vector *	auth_ids,
		struct ast_sip_auth_objects_vector *	auth_objects
	)

Retrieve relevant SIP auth structures from sorcery as a vector.

Parameters

	auth_ids	Vector of sorcery IDs of auth credentials to retrieve
[out]	auth_objects	A pointer ast_sip_auth_objects_vector to hold the objects

Return values

0	Success
-1	Number of auth objects found is less than the number of names supplied.

Warning

The number of auth objects retrieved may be less than the number of auth ids supplied if auth objects couldn't be found for some of them.

Note

Since the ref count on all auth objects returned has been bumped, you must call ast_sip_cleanup_auth_objects_vector() to decrement the ref count on all of the auth objects in the vector, then call AST_VECTOR_FREE() on the vector itself.

ast_sip_rewrite_uri_to_local()

int ast_sip_rewrite_uri_to_local	(	pjsip_sip_uri *	uri,

	)

Replace domain and port of SIP URI to point to (external) signaling address of this Asterisk instance.

Parameters

uri
tdata

Return values

0	success
-1	failure

Note

Uses domain and port in Contact header if it exists, otherwise the local URI of the dialog is used if the message is sent within the context of a dialog. Further, NAT settings are considered - i.e. if the target is not in the localnet, the external_signaling_address and port are used.

ast_sip_send_out_of_dialog_request()

		struct ast_sip_endpoint *	endpoint,
		int	timeout,
		void *	token,
		void(*)(void *token, pjsip_event *e)	callback
	)

General purpose method for sending an Out-Of-Dialog SIP request.

This is a companion function for ast_sip_create_request. The request created there can be passed to this function, though any request may be passed in.

This will automatically set up handling outbound authentication challenges if they arrive.

Parameters

tdata	The request to send
endpoint	Optional. If specified, the out-of-dialog request is sent to the endpoint.
timeout	If non-zero, after the timeout the transaction will be terminated and the callback will be called with the PJSIP_EVENT_TIMER type.
token	Data to be passed to the callback upon receipt of out-of-dialog response.
callback	Callback to be called upon receipt of out-of-dialog response.

Return values

0	Success
-1	Failure (out-of-dialog callback will not be called.)

Note

Timeout processing: There are 2 timers associated with this request, PJSIP timer_b which is set globally in the "system" section of pjsip.conf, and the timeout specified on this call. The timer that expires first (before normal completion) will cause the callback to be run with e->body.tsx_state.type = PJSIP_EVENT_TIMER. The timer that expires second is simply ignored and the callback is not run again.

int ast_sip_send_response	(	pjsip_response_addr *	res_addr,

Send a response to an out of dialog request.

Use this function sparingly, since this does not create a transaction within PJSIP. This means that if the request is retransmitted, it is your responsibility to detect this and not process the same request twice, and to send the same response for each retransmission.

Send a stateful response to an out of dialog request.

This creates a transaction within PJSIP, meaning that if the request that we are responding to is retransmitted, we will not attempt to re-handle the request.

Parameters
