2014-06-23core_unreal: Fix off by one buffer overwrite error.Richard Mudgett
Appending the ;2 to the user supplied ;1 uniqueid to create the ;2 version if the user did not also supply an extra uniqueid for the ;2 channel resulted in allocating a buffer that was one byte too small. * Fix off by one error in ast_unreal_new_channels() when generating the ;2 uniqueid from the user suppled ;1 version. * Pulled some long assignment lines from if tests to improve line break readability in ast_unreal_new_channels(). ........

2014-05-25core_unreal: Prevent double free of core_unreal pvtMatthew Jordan
When a channel is destroyed (such as via ast_channel_release in off nominal paths in core_unreal), it will attempt to free (via ast_free) the channel tech pvt. This is problematic for a few reasons: 1. The channel tech pvt is an ao2 object in core_unreal. Free'ing the pvt directly is no good. 2. The channel tech pvt's reference count is dropped just prior to calling ast_channel_release, resulting in the pvt's destruction. Hence, the channel destructor is free'ing an invalid pointer. This patch keeps the dropping of the reference count, but sets the pvt to NULL on the channel prior to releasing it. This models what would occur if the channel was hung up directly. ........

2014-03-20assigned-uniqueids: Miscellaneous cleanup and fixes.Richard Mudgett
* Fix memory leak in ast_unreal_new_channels(). Made it generate the ;2 uniqueid on a stack variable instead of mallocing it. * Made send error response to ARI and AMI requests instead of just logging excessive uniqueid length and allowing truncation. action_originate() and ari_channels_handle_originate_with_id(). * Fixed minor truncating uniqueid hole when generating the ;2 uniqueid string length. Created public and internal lengths of uniqueid. The internal length can handle a max public uniqueid plus an appended ;2. * free() and ast_free() are NULL tolerant so they don't need a NULL test before calling. * Made use better struct initialization format instead of the position dependent initialization format. Also anything not explicitly initialized in the struct is initialized to zero by the compiler. * Made ast_channel_internal_set_fake_ids() use the safer ast_copy_string() instead of strncpy().

2014-03-07uniqueid: channel linkedid, ami, ari object creation with id'sScott Griepentrog
Much needed was a way to assign id to objects on creation, and much change was necessary to accomplish it. Channel uniqueids and linkedids are split into separate string and creation time components without breaking linkedid propgation. This allowed the uniqueid to be specified by the user interface - and those values are now carried through to channel creation, adding the assignedids value to every function in the chain including the channel drivers. For local channels, the second channel can be specified or left to default to a ;2 suffix of first. In ARI, bridge, playback, and snoop objects can also be created with a specified uniqueid. Along the way, the args order to allocating channels was fixed in chan_mgcp and chan_gtalk, and linkedid is no longer lost as masquerade occurs.

2013-12-03Add channel locking for channel snapshot creation.Mark Michelson
This adds channel locks around calls to create channel snapshots as well as other functions which operate on a channel and then end up creating a channel snapshot. Functions that expect the channel to be locked prior to being called have had their documentation updated to indicate such. ........

2013-09-13Restore Dial, Queue, and FollowMe 'I' option support.Richard Mudgett
The Dial, Queue, and FollowMe applications need to inhibit the bridging initial connected line exchange in order to support the 'I' option. * Replaced the pass_reference flag on ast_bridge_join() with a flags parameter to pass other flags defined by enum ast_bridge_join_flags. * Replaced the independent flag on ast_bridge_impart() with a flags parameter to pass other flags defined by enum ast_bridge_impart_flags. * Since the Dial, Queue, and FollowMe applications are now the only callers of ast_bridge_call() and ast_bridge_call_with_flags(), changed the calling contract to require the initial COLP exchange to already have been done by the caller. * Made all callers of ast_bridge_impart() check the return value. It is important. As a precaution, I also made the compiler complain now if it is not checked. * Did some cleanup in parking_tests.c as a result of checking the ast_bridge_impart() return value. An independent, but associated change is: * Reduce stack usage in ast_indicate_data() and add a dropping redundant connected line verbose message.

2013-09-12core_local: Fix memory corruption race condition.Richard Mudgett
The masquerade super test is failing on v12 with high fence violations and crashing. The fence violations are showing that party id allocated memory strings are somehow getting corrupted in the bridge_reconfigured_connected_line_update() function. The invalid string values happen to be the freed memory fill pattern. After much puzzling, I deduced that the bridge_reconfigured_connected_line_update() is copying a string out of the source channel's caller party id struct just as another thread is updating it with a new value. The copying thread is using the old string pointer being freed by the updating thread. A search of the code found the unreal_colp_redirect_indicate() routine updating the caller party id's without holding the channel lock. A latent bug in v1.8 and v11 hatched in v12 because of the bridging and connected line changes. :) (issue ASTERISK-22221) Reported by: Matt Jordan Review: https://reviewboard.asterisk.org/r/2839/ ........

2013-08-09bridge_channel: Support the lonely flag and make ARI use it.Jonathan Rose
The lonely flag is an optional flag for bridge channels that will make them leave a bridge when a channel leaves if only lonely channels are in the bridge at that point. This is useful for things like ending recording and playback channels when they cease to be interacting with other channels in the bridge.

2013-07-25A great big renaming patchMatthew Jordan
This patch renames the bridging* files to bridge*. This may seem pedantic and silly, but it fits better in line with current Asterisk naming conventions: * channel is not "channeling" * monitor is not "monitoring" etc. A bridge is an object. It is a first class citizen in Asterisk. "Bridging" is the act of using a bridge on a set of channels - and the API that fulfills that role is more than just the action.

Adds a new channel driver for creating channels for specific purposes in bridges, primarily to act as either recorders or announcers. Adds ARI commands for playing announcements to ever participant in a bridge as well as for recording a bridge.

2013-07-08Create Local channel messages on the Stasis message bus and produce AMI eventsMatthew Jordan
This patch does the following: * It adds a virtual table of callbacks to core_unreal. These callbacks can be supplied by concrete implementations of "unreal" channel drivers, which lets the unreal channel driver call specific functionality when it performs some action. Currently, this is done to notify implementations when an optimization operation has begun, and when an optimization operation has succeeded. * It adds Stasis-Core messages for Local channel bridging and Local channel optimization. Local channel optimization is now two events: a Begin and an End. Some consumers of Stasis-Core may want to know when an operation is beginning so that they can 'prepare' their information; others will be more concerned about when the operation has completed, so that they can 'fix up' information. Stasis-Core allows for both, as does AMI. Review: https://reviewboard.asterisk.org/r/2552 git-svn-id: https://origsvn.digium.com/svn/asterisk/trunk@393801 65c4cc65-6c06-0410-ace0-fbb531ad65f3
