Naveen Albert	af17973bda	func_frame_drop: New function ... Adds function to selectively drop specified frames in the TX or RX direction on a channel, including control frames. ASTERISK-29478 Change-Id: I8147c9d55d74e2e48861edba6b22f930920541ec	4 years ago
Jaco Kroon	2dbf8cd135	func_lock: Add "dialplan locks show" cli command. ... For example: arthur*CLI> dialplan locks show func_lock locks: Name Requesters Owner uls-autoref 0 (unlocked) 1 total locks listed. Obviously other potentially useful stats could be added (eg, how many times there was contention, how many times it failed etc ... but that would require keeping the stats and I'm not convinced that's worth the effort. This was useful to troubleshoot some other issues so submitting it. Change-Id: Ib875e56feb49d523300aec5f36c635ed74843a9f Signed-off-by: Jaco Kroon <jaco@uls.co.za>	4 years ago
Jaco Kroon	5d7d174e1f	func_lock: Prevent module unloading in-use module. ... The scenario where a channel still has an associated datastore we cannot unload since there is a function pointer to the destroy and fixup functions in play. Thus increase the module ref count whenever we allocate a datastore, and decrease it during destroy. In order to tighten the race that still exists in spite of this (below) add some extra failure cases to prevent allocations in these cases. Race: If module ref is zero, an LOCK or TRYLOCK is invoked (near) simultaneously on a channel that has NOT PREVIOUSLY taken a lock, and if in such a case the datastore is created *prior* to unloading being set to true (first step in module unload) then it's possible that the module will unload with the destructor being called (and segfault) post the module being unloaded. The module will however wait for such locks to release prior to unloading. If post that we can recheck the module ref before returning the we can (in theory, I think) eliminate the last of the race. This race is mostly theoretical in nature. Change-Id: I21a514a0b56755c578a687f4867eacb8b59e23cf Signed-off-by: Jaco Kroon <jaco@uls.co.za>	4 years ago
Jaco Kroon	4040095ea4	func_lock: Fix memory corruption during unload. ... AST_TRAVERSE accessess current as current = current->(field).next ... and since we free current (and ast_free poisons the memory) we either end up on a ast_mutex_lock to a non-existing lock that can never be obtained, or a segfault. Incidentally add logging in the "we have to wait for a lock to release" case, and remove an ineffective statement that sets memory that was just cleared by ast_calloc to zero.

Jaco Kroon	d847f7e8f8	func_odbc: Introduce minargs config and expose ARGC in addition to ARGn. ... minargs enables enforcing of minimum count of arguments to pass to func_odbc, so if you're unconditionally using ARG1 through ARG4 then this should be set to 4. func_odbc will generate an error in this case, so for example [FOO] minargs = 4 and ODBC_FOO(a,b,c) in dialplan will now error out instead of using a potentially leaked ARG4 from Gosub(). ARGC is needed if you're using optional argument, to verify whether or not an argument has been passed, else it's possible to use a leaked ARGn from Gosub (app_stack). So now you can safely do ${IF($[${ARGC}>3]?${ARGV}:default value)} kind of thing. Change-Id: I6ca0b137d90b03f6aa9c496991f6cbf1518f6c24 Signed-off-by: Jaco Kroon <jaco@uls.co.za>	4 years ago
Jaco Kroon	32e36144c7	func_lock: fix multiple-channel-grant problems. ... Under contention it becomes possible that multiple channels will be told they successfully obtained the lock, which is a bug. Please refer ASTERISK-29217 This introduces a couple of changes. 1. Replaces requesters ao2 container with simple counter (we don't really care who is waiting for the lock, only how many). This is updated undex ->mutex to prevent memory access races. 2. Correct semantics for ast_cond_timedwait() as described in pthread_cond_broadcast(3P) is used (multiple threads can be released on a single _signal()). 3. Module unload races are taken care of and memory properly cleaned up. Change-Id: I6f68b5ec82ff25b2909daf6e4d19ca864a463e29 Signed-off-by: Jaco Kroon <jaco@uls.co.za>	4 years ago

Martin Tomec	37dcdd485a	func_curl.c: Support custom http headers ... When user wants to send json data, the default Content-Type header is incorect (application/x-www-form-urlencoded).

This approach is not consistent with other parameters, but is more readable in dialplan than one call with multiple headers.

Joshua Colp	6647be69ac	func_jitterbuffer: Add audio/video sync support. ... This change adds support to the JITTERBUFFER dialplan function for audio and video synchronization. When enabled the RTCP SR report is used to produce an NTP timestamp for both the audio and video streams. Using this information the video frames are queued until their NTP timestamp is equal to or behind the NTP timestamp of the audio. The audio jitterbuffer acts as the leader deciding when to shrink/grow the jitterbuffer when adaptive is in use. For both adaptive and fixed the video buffer follows the size of the audio jitterbuffer. ASTERISK-28533 Change-Id: I3fd75160426465e6d46bb2e198c07b9d314a4492	6 years ago
Kevin Harwell	6bb14150c4	various modules: json integer overflow ... There were still a few places in the code that could overflow when "packing" a json object with a value outside the base type integer's range. For instance: unsigned int value = INT_MAX + 1 ast_json_pack("{s: i}", value); would result in a negative number being "packed". In those situations this patch alters those values to a ast_json_int_t, which widens the value up to a long or long long.

Joshua Colp	44254d548b	res_odbc: Add basic query logging. ... When Asterisk is connected and used with a database the response time of the database can cause problems in Asterisk if it is long. Normally the only way to see this problem would be to retrieve a backtrace from Asterisk and examine where things are blocked, or examine the database to see if there is any indication of a problem. This change adds some basic query logging to make it easier to investigate such a problem. When logging is enabled res_odbc will now keep track of the number of queries executed, as well as the query that has taken the longest time to execute. There is also an option which will cause a WARNING message to be output if a query takes longer than a configurable amount of time to execute. This makes it easier and clearer for users that their database may be experiencing a problem that could impact Asterisk.

Joshua Colp	882e79b77e	pjsip: Rewrite OPTIONS support with new eyes. ... The OPTIONS support in PJSIP has organically grown, like many things in Asterisk. It has been tweaked, changed, and adapted based on situations run into. Unfortunately this has taken its toll. Configuration file based objects have poor performance and even dynamic ones aren't that great. This change scraps the existing code and starts fresh with new eyes. It leverages all of the APIs made available such as sorcery observers and serializers to provide a better implementation. 1. The state of contacts, AORs, and endpoints relevant to the qualify process is maintained. This state can be updated by external forces (such as a device registering/unregistering) and also the reload process. This state also includes the association between endpoints and AORs. 2. AORs are scheduled and not contacts. This reduces the amount of work spent juggling scheduled items. 3. Manipulation of which AORs are being qualified and the endpoint states all occur within a serializer to reduce the conflict that can occur with multiple threads attempting to modify things. 4. Operations regarding an AOR use a serializer specific to that AOR. 5. AORs and endpoint state act as state compositors. They take input from lower level objects (contacts feed AORs, AORs feed endpoint state) and determine if a sufficient enough change has occurred to be fed further up the chain. 6. Realtime is supported by using observers to know when a contact has been registered. If state does not exist for the associated AOR then it is retrieved and becomes active as appropriate. The end result of all of this is best shown with a configuration file of 3000 endpoints each with an AOR that has a static contact. In the old code it would take over a minute to load and use all 8 of my cores. This new code takes 2-3 seconds and barely touches the CPU even while dealing with all of the OPTIONS requests.

George Joseph	4fb7967c73	bridge_softmix: Forward TEXT frames ... Core bridging and, more specifically, bridge_softmix have been enhanced to relay received frames of type TEXT or TEXT_DATA to all participants in a softmix bridge. res_pjsip_messaging and chan_pjsip have been enhanced to take advantage of this so when res_pjsip_messaging receives an in-dialog MESSAGE message from a user in a conference call, it's relayed to all other participants in the call. res_pjsip_messaging already queues TEXT frames to the channel when it receives an in-dialog MESSAGE from an endpoint and chan_pjsip will send an MESSAGE when it gets a TEXT frame. On a normal point-to-point call, the frames are forwarded between the two correctly. bridge_softmix was not though so messages weren't getting forwarded to conference bridge participants. Even if they were, the bridging code had no way to tell the participants who sent the message so it would look like it came from the bridge itself. * The TEXT frame type doesn't allow storage of any meta data, such as sender, on the frame so a new TEXT_DATA frame type was added that uses the new ast_msg_data structure as its payload. A channel driver can queue a frame of that type when it receives a message from outside. A channel driver can use it for sending messages by implementing the new send_text_data channel tech callback and setting the new AST_CHAN_TP_SEND_TEXT_DATA flag in its tech properties. If set, the bridging/channel core will use it instead of the original send_text callback and it will get the ast_msg_data structure. Channel drivers aren't required to implement this. Even if a TEXT_DATA enabled driver uses it for incoming messages, an outgoing channel driver that doesn't will still have it's send_text callback called with only the message text just as before. * res_pjsip_messaging now creates a TEXT_DATA frame for incoming in-dialog messages and sets the "from" to the display name in the "From" header, or if that's empty, the caller id name from the channel. This allows the chat client user to set a friendly name for the chat. * bridge_softmix now forwards TEXT and TEXT_DATA frames to all participants (except the sender). * A new function "ast_sendtext_data" was added to channel which takes an ast_msg_data structure and calls a channel's send_text_data callback, or if that's not defined, the original send_text callback. * bridge_channel now calls ast_sendtext_data for TEXT_DATA frame types and ast_sendtext for TEXT frame types. * chan_pjsip now uses the "from" name in the ast_msg_data structure (if it exists) to set the "From" header display name on outgoing text messages.
