George Joseph	709be42bc3	options: Change ast_options from ast_flags to ast_flags64. ... DeveloperNote: The 32-bit ast_options has no room left to accomodate new options and so has been converted to an ast_flags64 structure. All internal references to ast_options have been updated to use the 64-bit flag manipulation macros. External module references to the 32-bit ast_options should continue to work on little-endian systems because the least-significant bytes of a 64 bit integer will be in the same location as a 32-bit integer. Because that's not the case on big-endian systems, we've swapped the bytes in the flags manupulation macros on big-endian systems so external modules should still work however you are encouraged to test.	3 months ago
Sean Bright	f042fb2153	docs: AMI documentation fixes. ... Most of this patch is adding missing PJSIP-related event documentation, but the one functional change was adding a sorcery to-string handler for endpoint's `redirect_method` which was not showing up in the AMI event details or `pjsip show endpoint <endpoint>` output. The rest of the changes are summarized below: * app_agent_pool.c: Typo fix Epoche -> Epoch. * stasis_bridges.c: Add missing AttendedTransfer properties. * stasis_channels.c: Add missing AgentLogoff properties. * pjsip_manager.xml: - Add missing AorList properties. - Add missing AorDetail properties. - Add missing ContactList properties. - Add missing ContactStatusDetail properties. - Add missing EventDetail properties. - Add missing AuthList properties. - Add missing AuthDetail properties. - Add missing TransportDetail properties. - Add missing EndpointList properties. - Add missing IdentifyDetail properties. * res_pjsip_registrar.c: Add missing InboundRegistrationDetail documentation. * res_pjsip_pubsub.c: - Add missing ResourceListDetail documentation. - Add missing InboundSubscriptionDetail documentation. - Add missing OutboundSubscriptionDetail documentation. * res_pjsip_outbound_registration.c: Add missing OutboundRegistrationDetail documentation.	8 months ago

George Joseph	772221c82a	docs: Add version information to configObject and configOption XML elements ... Most of the configObjects and configOptions that are implemented with ACO or Sorcery now have `<since>/<version>` elements added. There are probably some that the script I used didn't catch. The version tags were determined by the following... * Do a git blame on the API call that created the object or option. * From the commit hash, grab the summary line. * Do a `git log --grep <summary>` to find the cherry-pick commits in all branches that match. * Do a `git patch-id` to ensure the commits are all related and didn't get a false match on the summary. * Do a `git tag --contains <commit>` to find the tags that contain each commit. * Weed out all tags not <major>.<minor>.0. * Sort and discard any <major>.0.0 and following tags where the commit appeared in an earlier branch. * The result is a single tag for each branch where the API was last touched. configObjects and configOptions elements implemented with the base ast_config APIs were just not possible to find due to the non-deterministic way they are accessed. Also note that if the API call was on modified after it was added, the version will be the one it was last modified in. Final note: The configObject and configOption elements were introduced in 12.0.0 so options created before then may not have any XML documentation.	9 months ago

InterLinked1	659f2aae3a	res_pjsip_pubsub: Add new pubsub module capabilities. (#82) ... The existing res_pjsip_pubsub APIs are somewhat limited in what they can do. This adds a few API extensions that make it possible for PJSIP pubsub modules to implement richer features than is currently possible. * Allow pubsub modules to get a handle to pjsip_rx_data on subscription * Allow pubsub modules to run a callback when a subscription is renewed * Allow pubsub modules to run a callback for outgoing NOTIFYs, with a handle to the tdata, so that modules can append their own headers to the NOTIFYs This change does not add any features directly, but makes possible several new features that will be added in future changes.

Mike Bradeen	e494a55467	res_pjsip_pubsub: subscription cleanup changes ... There are two main parts of the change associated with this commit. These are driven by the change in call order of pubsub_on_rx_refresh and pubsub_on_evsub_state by pjproject when an in-dialog SUBSCRIBE is received. First, the previous behavior was for pjproject to call pubsub_on_rx_refresh before calling pubsub_on_evsub_state when an in-dialog SUBSCRIBE was received that changes the subscription state. If that change was a termination due to a re-SUBSCRIBE with an expires of 0, we used to use the call to pubsub_on_rx_refresh to set the substate of the evsub to TERMINATE_PENDING before pjproject could call pubsub_on_evsub_state. This substate let pubsub_on_evsub_state know that the subscription TERMINATED event could be ignored as there was still a subsequent NOTIFY that needed to be generated and another call to pubsub_on_evsub_state to come with it. That NOTIFY was sent via serialized_pubsub_on_refresh_timeout which would see the TERMINATE_PENDING state and transition it to TERMINATE_IN_PROGRESS before triggering another call to pubsub_on_evsub_state (which now would clean up the evsub.) The new pjproject behavior is to call pubsub_on_evsub_state before pubsub_on_rx_refresh. This means we no longer can set the state to TERMINATE_PENDING to tell pubsub_on_evsub_state that it can ignore the first TERMINATED event. To handle this, we now look directly at the event type, method type and the expires value to determine whether we want to ignore the event or use it to trigger the evsub cleanup. Second, pjproject now expects the NOTIFY to actually be sent during pubsub_on_rx_refresh and avoids the protocol violation inherent in sending a NOTIFY before the SUBSCRIBE is acknowledged by caching the sent NOTIFY then sending it after responding to the SUBSCRIBE. This requires we send the NOTIFY using the non-serialized pubsub_on_refresh_timeout directly and let pjproject handle the protocol violation.

Mike Bradeen	b44ffd0565	res_pjsip: Prevent SEGV in pjsip_evsub_send_request ... contributed pjproject - patch to check sub->pending_notify in evsub.c:on_tsx_state before calling pjsip_evsub_send_request() res_pjsip_pubsub - change post pjsip 2.13 behavior to use pubsub_on_refresh_timeout to avoid the ao2_cleanup call on the sub_tree. This is is because the final NOTIFY send is no longer the last place the sub_tree is referenced. ASTERISK-30419 Change-Id: Ib5cc662ce578e9adcda312e16c58a10b6453e438	3 years ago
Mike Bradeen	62a64686e2	res_pjsip: Upgraded bundled pjsip to 2.13 ... Removed multiple patches. Code chages in res_pjsip_pubsub due to changes in evsub. Pjsip now calls on_evsub_state() before on_rx_refresh(), so the sub tree deletion that used to take place in on_evsub_state() now must take place in on_rx_refresh(). Additionally, pjsip now requires that you send the NOTIFY from within on_rx_refresh(), otherwise it will assert when going to send the 200 OK. The idea is that it will look for this NOTIFY and cache it until after sending the response in order to deal with the self-imposed message mis-order. Asterisk previously dealt with this by pushing the NOTIFY in on_rx_refresh(), but pjsip now forces us to use it's method. Changes were required to configure in order to detect which way pjsip handles this as the two are not compatible for the reasons mentioned above. A corresponding change in testsuite is required in order to deal with the small interal timing changes caused by moving the NOTIFY send.

George Joseph	120aca73ba	pjsip_transport_events: Fix possible use after free on transport ... It was possible for a module that registered for transport monitor events to pass in a pjsip_transport that had already been freed. This caused pjsip_transport_events to crash when looking up the monitor for the transport. The fix is a two pronged approach. 1. We now increment the reference count on pjsip_transports when we create monitors for them, then decrement the count when the transport is going to be destroyed. 2. There are now APIs to register and unregister monitor callbacks by "transport key" which is a string concatenation of the remote ip address and port. This way the module needing to monitor the transport doesn't have to hold on to the transport object itself to unregister. It just has to save the transport_key. * Added the pjsip_transport reference increment and decrement. * Changed the internal transport monitor container key from the transport->obj_name (which may not be unique anyway) to the transport_key. * Added a helper macro AST_SIP_MAKE_REMOTE_IPADDR_PORT_STR() that fills a buffer with the transport_key using a passed-in pjsip_transport. * Added the following functions: ast_sip_transport_monitor_register_key ast_sip_transport_monitor_register_replace_key ast_sip_transport_monitor_unregister_key and marked their non-key counterparts as deprecated. * Updated res_pjsip_pubsub and res_pjsip_outbound_register to use the new "key" monitor functions. NOTE: res_pjsip_registrar also uses the transport monitor functionality but doesn't have a persistent object other than contact to store a transport key. At this time, it continues to use the non-key monitor functions. ASTERISK-30244 Change-Id: I1a20baf2a8643c272dcf819871d6c395f148f00b (cherry picked from commit 7684c9e907)	3 years ago

Alexei Gradinari	d1900d4a4c	res_pjsip_pubsub: RLS 'uri' list attribute mismatch with SUBSCRIBE request ... When asterisk generates the RLMI part of NOTIFY request, the asterisk uses the local contact uri instead of the URI to which the SUBSCRIBE request is sent. Because of this mismatch some IP phones (for example Cisco 5XX) ignore this list. According https://datatracker.ietf.org/doc/html/rfc4662#section-5.2 The first mandatory <list> attribute is "uri", which contains the uri that corresponds to the list. Typically, this is the URI to which the SUBSCRIBE request was sent. https://datatracker.ietf.org/doc/html/rfc4662#section-5.3 The "uri" attribute identifies the resource to which the <resource> element corresponds. Typically, this will be a SIP URI that, if subscribed to, would return the state of the resource. This patch makes asterisk to generate URI using SUBSCRIBE request URI.

Alexei Gradinari	a2aa881dcb	res_pjsip_pubsub: fix Batched Notifications stop working ... If Subscription refresh occurred between when the batched notification was scheduled and the serialized notification was to be sent, then new schedule notification task would never be added. There are 2 threads: thread #1. ast_sip_subscription_notify is called, if notification_batch_interval then call schedule_notification. 1.1. The schedule_notification checks notify_sched_id > -1 not true, then send_scheduled_notify = 1 notify_sched_id = ast_sched_add(sched, sub_tree->notification_batch_interval, sched_cb.... 1.2. The sched_cb pushes task serialized_send_notify to serializer and returns 0 which means no reschedule. 1.3. The serialized_send_notify checks send_scheduled_notify if it's false the just returns. BUT notify_sched_id is still set, so no more ast_sched_add. thread #2. pubsub_on_rx_refresh is called 2.1 it pushes serialized_pubsub_on_refresh_timeout to serializer 2.2. The serialized_pubsub_on_refresh_timeout calls pubsub_on_refresh_timeout which calls send_notify 2.3. The send_notify set send_scheduled_notify = 0; The serialized_send_notify should always unset notify_sched_id. ASTERISK-29904 #close Change-Id: Ifc50c00b213c396509e10326a1ed89d8cf8c7875	4 years ago

If this option is enabled, the Display Name will be provided. This option is disabled by default to remain the previous behavior.

Kevin Harwell	b82f880647	AST-2020-001 - res_pjsip: Return dialog locked and referenced ... pjproject returns the dialog locked and with a reference. However, in Asterisk the method that handles this decrements the reference and removes the lock prior to returning. This makes it possible, under some circumstances, for another thread to free said dialog before the thread that created it attempts to use it again. Of course when the thread that created it tries to use a freed dialog a crash can occur. This patch makes it so Asterisk now returns the newly created dialog both locked, and with an added reference. This allows the caller to de-reference, and unlock the dialog when it is safe to do so. In the case of a new SIP Invite the lock, and reference are now held for the entirety of the new invite handling process. Otherwise it's possible for the dialog, or its dependent objects, like the transaction, to disappear. For example if there is a TCP transport error.

Kevin Harwell	415b55af5a	pjproject: Upgrade bundled version to pjproject 2.10 ... This patch makes the usual necessary changes when upgrading to a new version pjproject. For instance, version number bump, patches removed from third-party, new *.md5 file added, etc.. This patch also includes a change to the Asterisk pjproject Makefile to explicitly create the 'source/pjsip-apps/lib' directory. This directory is no longer there by default so needs to be added so the Asterisk malloc debug can be built. This patch also includes some minor changes to Asterisk that were a result of the upgrade. Specifically, there was a backward incompatibility change made in 2.10 that modified the "expires header" variable field from a signed to an unsigned value. This potentially effects comparison. Namely, those check for a value less than zero. This patch modified a few locations in the Asterisk code that may have been affected. Lastly, this patch adds a new macro PJSIP_MINVERSION that can be used to check a minimum version of pjproject at compile time.

Joshua C. Colp	4e7adbd8f4	res_pjsip_pubsub: Add ability to persist generator state information. ...

This data is persisted out alongside the normal persistence information and allows the body generator to restore state information or to simply use this for normal storage of state. State is stored in the form of JSON and it is up to the body generator to interpret this as needed. The dialog-info+xml body generator has been updated to take advantage of this to persist the version number. ASTERISK-27759 Change-Id: I5fda56c624fd13c17b3c48e0319b77079e9e27de	6 years ago

Richard Mudgett	237d341bbd	res_pjsip.c: Split ast_sip_push_task_synchronous() to fit expectations. ... ast_sip_push_task_synchronous() did not necessarily execute the passed in task under the specified serializer. If the current thread is any registered pjsip thread then it would execute the task immediately instead of under the specified serializer. Reentrancy issues could result if the task does not execute with the right serializer. The original reason ast_sip_push_task_synchronous() checked to see if the current thread was a registered pjsip thread was because of a deadlock with masquerades and the channel technology's fixup callback (ASTERISK_22936). A subsequent masquerade deadlock fix (ASTERISK_24356) involving call pickups avoided the original deadlock situation entirely. The PJSIP channel technology's fixup callback no longer needed to call ast_sip_push_task_synchronous(). However, there are a few places where this unexpected behavior is still required to avoid deadlocks. The pjsip monitor thread executes callbacks that do calls to ast_sip_push_task_synchronous() that would deadlock if the task were actually pushed to the specified serializer. I ran into one dealing with the pubsub subscriptions where an ao2 destructor called ast_sip_push_task_synchronous(). * Split ast_sip_push_task_synchronous() into ast_sip_push_task_wait_servant() and ast_sip_push_task_wait_serializer(). ast_sip_push_task_wait_servant() has the old behavior of ast_sip_push_task_synchronous(). ast_sip_push_task_wait_serializer() has the new behavior where the task is always executed by the specified serializer or a picked serializer if one is not passed in. Both functions behave the same if the current thread is not a SIP servant. * Redirected ast_sip_push_task_synchronous() to ast_sip_push_task_wait_servant() to preserve API for released branches.

Richard Mudgett	97cc67b12f	res_pjsip: Fix deadlock on reliable transport shutdown. ... A deadlock can happen when the PJSIP monitor thread is shutting down a connection oriented transport (TCP/TLS) used by a subscription at the same time as another thread tries to send something for that subscription. The deadlock is between the pjsip monitor thread attempting to get the dialog lock and another thread sending something for that dialog when it tries to get the transport manager lock. * res_pjsip_pubsub.c: Avoid the deadlock by pushing the subscription removal to the subscription serializer. * res_pjsip_registrar.c: Pushed off incoming registration contact removals to a default serializer as a precaution. Removing the contacts involves sorcery access which in this case will involve database access. Depending upon the setup, the database may not be on the same machine and could take awhile. We don't want to hold up the pjsip monitor thread with potentially long access times. ASTERISK-27706 Change-Id: I56b647aea565f24dba33e9e5ebeed4cd3f31f8c4	8 years ago
Joshua Colp	d424850d58	AST-2018-004: Restrict the number of Accept headers in a SUBSCRIBE. ... When receiving a SUBSCRIBE request the Accept headers from it are stored locally. This operation has a fixed limit of 32 Accept headers but this limit was not enforced. As a result it was possible for memory outside of the allocated space to get written to resulting in a crash. This change enforces the limit so only 32 Accept headers are processed. ASTERISK-27640 Reported By: Sandro Gauci Change-Id: I99a814b10b554b13a6021ccf41111e5bc95e7301	8 years ago
George Joseph	2b9aa6b5bb	res_pjsip_pubsub: Prune subs with reliable transports at startup ... In an earlier release, inbound registrations on a reliable transport were pruned on Asterisk restart since the TCP connection would have been torn down and become unusable when Asterisk stopped. This same process is now also applied to inbound subscriptions. Also fixed issues in res_pjsip_registrar where it wasn't handling the monitoring correctly when multiple registrations came in over the same transport. To accomplish this, the pjsip_transport_event feature needed to be refactored to allow multiple monitors (multiple subcriptions or registrations from the same endpoint) to exist on the same transport. Since this changed the API, any external modules that may have used the transport monitor feature (highly unlikey) will need to be changed.

Corey Farrell	527cf5a570	Remove redundant module checks and references. ... This removes references that are no longer needed due to automatic references created by module dependencies. In addition this removes most calls to ast_module_check as they were checking modules which are listed as dependencies. Change-Id: I332a6e8383d4c72c8e89d988a184ab8320c4872e	8 years ago

Kevin Harwell	553306548c	AST-2017-014: res_pjsip - Missing contact header can cause crash ... Those SIP messages that create dialogs require a contact header to be present. If the contact header was missing from the message it could cause Asterisk to crash. This patch checks to make sure SIP messages that create a dialog contain the contact header. If the message does not and it is required Asterisk now returns a "400 Missing Contact header" response. Also added NULL checks when retrieving the contact header that were missing as a "just in case". ASTERISK-27480 #close Change-Id: I1810db87683fc637a9e3e1384a746037fec20afe	8 years ago
