The 'e' extension is a fall back for the 'i', 't', or 'T' extensions if any of them do not exist. Many of the places the 'e' extension was supposed to be invoked fail because the priority was set wrong. There were two places where the 'e' extension was not even checked for fall back. * Made invoke the 'e' extension similarly to the previous 'i', 't', or 'T' extension check and added the 'e' extension as a fall back to the two missing locations. * Prioritized and optimized some hangup tests associated with the 'e' extension.

David Vossel	c26c190711	Asterisk media architecture conversion - no more format bitfields ... This patch is the foundation of an entire new way of looking at media in Asterisk. The code present in this patch is everything required to complete phase1 of my Media Architecture proposal. For more information about this project visit the link below. https://wiki.asterisk.org/wiki/display/AST/Media+Architecture+Proposal The primary function of this patch is to convert all the usages of format bitfields in Asterisk to use the new format and format_cap APIs. Functionally no change in behavior should be present in this patch. Thanks to twilson and russell for all the time they spent reviewing these changes.

Mantis issue #18585 reports that a channel redirect out of MeetMe() stopped working properly. This issue includes a patch that resolves the issue by removing a call to ast_check_hangup() from app_meetme.c. I left that in my patch, as it doesn't need to be there. However, the rest of the patch fixes this problem with or without the change to app_meetme. The key difference between what happens before and after this patch is the effect of the END_OF_Q control frame. After END_OF_Q is hit in ast_read(), ast_read() will return NULL. With the ast_check_hangup() removed, app_meetme sees this which causes it to exit as intended. Checking ast_check_hangup() caused app_meetme to exit earlier in the process, and the target of the redirect saw the condition where ast_read() returned NULL. Removing ast_check_hangup() works around the issue in app_meetme, but doesn't solve the issue if another application did the same thing. There are also other edge cases where if an application finishes at the same time that a redirect happens, the target of the redirect will think that the channel hung up. So, I made some changes in pbx.c to resolve it at a deeper level. There are already places that unset the SOFTHANGUP_ASYNCGOTO flag in an attempt to abort the hangup process. My patch extends this to remove the END_OF_Q frame from the channel's read queue, making the "abort hangup" more complete. This same technique was used in every place where a softhangup flag was cleared.

To recreate the problem: 1) Party A calls Party B 2) Invoke CLI "channel redirect" command to redirect channel call leg associated with A. 3) All associated channels are hung up. Note that if the CLI command were done on the channel call leg associated with B it works. This regression was a result of the fix for issue #16946 (https://reviewboard.asterisk.org/r/740/). The regression affects all features that use an async goto to execute the dialplan because of an external event: Channel redirect, AMI redirect, SIP REFER, and FAX detection. The struct ast_channel._softhangup code is a mess. The variable is used for several purposes that do not necessarily result in the call being hung up. I have added doxygen comments to describe how the various _softhangup bits are used. I have corrected all the places where the variable was tested in a non-bit oriented manner. The primary fix is the new AST_CONTROL_END_OF_Q frame. It acts as a weak hangup request so the soft hangup requests that do not normally result in a hangup do not hangup.

Richard Mudgett	ec37ffbdaf	ast_callerid restructuring ... The purpose of this patch is to eliminate struct ast_callerid since it has turned into a miscellaneous collection of various party information. Eliminate struct ast_callerid and replace it with the following struct organization: struct ast_party_name { char *str; int char_set; int presentation; unsigned char valid; }; struct ast_party_number { char *str; int plan; int presentation; unsigned char valid; }; struct ast_party_subaddress { char *str; int type; unsigned char odd_even_indicator; unsigned char valid; }; struct ast_party_id { struct ast_party_name name; struct ast_party_number number; struct ast_party_subaddress subaddress; char *tag; }; struct ast_party_dialed { struct { char *str; int plan; } number; struct ast_party_subaddress subaddress; int transit_network_select; }; struct ast_party_caller { struct ast_party_id id; char *ani; int ani2; }; The new organization adds some new information as well. * The party name and number now have their own presentation value that can be manipulated independently. ISDN supplies the presentation value for the name and number at different times with the possibility that they could be different. * The party name and number now have a valid flag. Before this change the name or number string could be empty if the presentation were restricted. Most channel drivers assume that the name or number is then simply not available instead of indicating that the name or number was restricted. * The party name now has a character set value. SIP and Q.SIG have the ability to indicate what character set a name string is using so it could be presented properly. * The dialed party now has a numbering plan value that could be useful to have available. The various channel drivers will need to be updated to support the new core features as needed. They have simply been converted to supply current functionality at this time. The following items of note were either corrected or enhanced: * The CONNECTEDLINE() and REDIRECTING() dialplan functions were consolidated into func_callerid.c to share party id handling code. * CALLERPRES() is now deprecated because the name and number have their own presentation values. * Fixed app_alarmreceiver.c write_metadata(). The workstring[] could contain garbage. It also can only contain the caller id number so using ast_callerid_parse() on it is silly. There was also a typo in the CALLERNAME if test. * Fixed app_rpt.c using ast_callerid_parse() on the channel's caller id number string. ast_callerid_parse() alters the given buffer which in this case is the channel's caller id number string. Then using ast_shrink_phone_number() could alter it even more. * Fixed caller ID name and number memory leak in chan_usbradio.c. * Fixed uninitialized char arrays cid_num[] and cid_name[] in sig_analog.c. * Protected access to a caller channel with lock in chan_sip.c. * Clarified intent of code in app_meetme.c sla_ring_station() and dial_trunk(). Also made save all caller ID data instead of just the name and number strings. * Simplified cdr.c set_one_cid(). It hand coded the ast_callerid_merge() function. * Corrected some weirdness with app_privacy.c's use of caller presentation.

Mark Michelson	10d65ad6b1	Fix potential invalid reads that could occur in pbx.c ... Here is a cut and paste of my review request for this change: This past weekend, Russell ran our current suite of unit tests for Asterisk under valgrind. The PBX pattern match test caused valgrind to spew forth two invalid read errors. This patch contains two changes that shut valgrind up and do not cause any new memory leaks. Change 1: In ast_context_remove_extension_callerid2, valgrind reported an invalid read in the for loop close to the function's end. Specifically, one of the the strcmp calls in the loop control was reading invalid memory. This was because the caller of ast_context_remove_extension_callerid2 (__ast_context destroy in this case) passed as a parameter a shallow copy of an ast_exten's exten field. This same ast_exten was what was destroyed inside the for loop, thus any iterations of the for loop beyond the destruction of the ast_exten would result in invalid reads. My fix for this is to make a copy of the ast_exten's exten field and pass the copy to ast_context_remove_extension_callerid2. In addition, I have also acted similarly with the ast_exten's matchcid field. Since in this case a NULL is handled quite differently than an empty string, I needed to be a bit more careful with its handling. Change 2: In __ast_context_destroy, we iterated over a hashtab and called ast_context_remove_extension_callerid2 on each item. Specifically, the hashtab over which we were iterating was an ast_exten's peer_table. Inside of ast_context_remove_extension_callerid2, we could possibly destroy this ast_exten, which also caused the hashtab to be freed. Attempting to call ast_hashtab_end_traversal on the hashtab iterator caused an invalid read to occur when trying to read the iterator->tab->do_locking field since iterator->tab had already been freed. My handling of this problem is a bit less straightforward. With each iteration over the hashtab's contents, we set a variable called "end_traversal" based on the return of ast_context_remove_extension_callerid2. If 0 is ever returned, then we know that the extension was found and destroyed. Because of this, we cannot call ast_hashtab_end_traversal because we will be guaranteeing a read of invalid memory. In such a case, we forego calling ast_hashtab_end_traversal and instead call ast_free on the hashtab iterator.

David Vossel	bebe42f3a7	fixes subscriptions being lost after 'module reload' ... During a module reload if multiple extension configs are present, such as both extensions.conf and extensions.ael, watchers for one config's hints will be lost during the merging of the other config. This happens because hint watchers are only preserved for the current config being merged. The old context list is destroyed after the merging takes place, meaning any watchers that were not perserved will be removed. Now all hints are preserved during merging regardless of what config file is being merged. These hints are only restored if they are present within the new context list.
