George Joseph	1e469a5e06	manager.c: Check for restricted file in action_createconfig. The `CreateConfig` manager action now ensures that a config file can only be created in the AST_CONFIG_DIR unless `live_dangerously` is set. Resolves: #1122	2 months ago
George Joseph	5470a23b48	swagger_model.py: Fix invalid escape sequence in get_list_parameter_type(). Recent python versions complain when backslashes in strings create invalid escape sequences. This causes issues for strings used as regex patterns like `'^List\[(.)\]$'` where you want the regex parser to treat `[` and `]` as literals. Double-backslashing is one way to fix it but simply converting the string to a raw string `re.match(r'^List\[(.)\]$', text)` is easier and less error prone.	2 months ago

George Joseph	076799be15	bridging: Fix multiple bridging issues causing SEGVs and FRACKs. Issues: * The bridging core allowed multiple bridges to be created with the same unique bridgeId at the same time. Only the last bridge created with the duplicate name was actually saved to the core bridges container. * The bridging core was creating a stasis topic for the bridge and saving it in the bridge->topic field but not increasing its reference count. In the case where two bridges were created with the same uniqueid (which is also the topic name), the second bridge would get the _existing_ topic the first bridge created. When the first bridge was destroyed, it would take the topic with it so when the second bridge attempted to publish a message to it it either FRACKed or SEGVd. * The bridge destructor, which also destroys the bridge topic, is run from the bridge manager thread not the caller's thread. This makes it possible for an ARI developer to create a new one with the same uniqueid believing the old one was destroyed when, in fact, the old one's destructor hadn't completed. This could cause the new bridge to get the old one's topic just before the topic was destroyed. When the new bridge attempted to publish a message on that topic, asterisk could either FRACK or SEGV. * The ARI bridges resource also allowed multiple bridges to be created with the same uniqueid but it kept the duplicate bridges in its app_bridges container. This created a situation where if you added two bridges with the same "bridge1" uniqueid, all operations on "bridge1" were performed on the first bridge created and the second was basically orphaned. If you attempted to delete what you thought was the second bridge, you actually deleted the first one created. Changes: * A new API `ast_bridge_topic_exists(uniqueid)` was created to determine if a topic already exists for a bridge. * `bridge_base_init()` in bridge.c and `ast_ari_bridges_create()` in resource_bridges.c now call `ast_bridge_topic_exists(uniqueid)` to check if a bridge with the requested uniqueid already exists and will fail if it does. * `bridge_register()` in bridges.c now checks the core bridges container to make sure a bridge doesn't already exist with the requested uniqueid. Although most callers of `bridge_register()` will have already called `bridge_base_init()`, which will now fail on duplicate bridges, there is no guarantee of this so we must check again. * The core bridges container allocation was changed to reject duplicate uniqueids instead of silently replacing an existing one. This is a "belt and suspenders" check. * A global mutex was added to bridge.c to prevent concurrent calls to `bridge_base_init()` and `bridge_register()`. * Even though you can no longer create multiple bridges with the same uniqueid at the same time, it's still possible that the bridge topic might be destroyed while a second bridge with the same uniqueid was trying to use it. To address this, the bridging core now increments the reference count on bridge->topic when a bridge is created and decrements it when the bridge is destroyed. * `bridge_create_common()` in res_stasis.c now checks the stasis app_bridges container to make sure a bridge with the requested uniqueid doesn't already exist. This may seem like overkill but there are so many entrypoints to bridge creation that we need to be safe and catch issues as soon in the process as possible. * The stasis app_bridges container allocation was changed to reject duplicate uniqueids instead of adding them. This is a "belt and suspenders" check. * The `bridge show all` CLI command now shows the bridge name as well as the bridge id. * Response code 409 "Conflict" was added as a possible response from the ARI bridge create resources to signal that a bridge with the requested uniqueid already exists. * Additional debugging was added to multiple bridging and stasis files.

George Joseph	4075d35ed3	.github: Change concurrency group ids so they're unique. GitHub strikes again. Apparently the github.ref context variable only contains the PR number if the workflow is triggered by "pull_request" so since we just changed the trigger to "pull_request_target" the variable no longer contains the PR number and is therefore not unique and can't be used as a concurrency group id. We now use `github.triggering_actor-github.head_ref`.	2 months ago
Mike Bradeen	d63c3e80fc	bridge_channel: don't set cause code on channel during bridge delete if already set Due to a potential race condition via ARI when hanging up a channel hangup with cause while also deleting a bridge containing that channel, the bridge delete can over-write the hangup cause code resulting in Normal Call Clearing instead of the set value. With this change, bridge deletion will only set the hangup code if it hasn't been previously set. Resolves: #1124	2 months ago

George Joseph	e65bf88bcf	.github: Refactor to use pull_request_target trigger. After careful review, we believe we can now use the "pull_request_target" workflow trigger instead of "pull_request" which required a separate privliged workflow to add labels and comments to PRs when they are submitted or updated. This allows us to greatly streamline our workflows and remove unneeded ones. * The OnPRChanged workflow was... * Renamed to OnPRCheck * Changed to trigger on pull_request_target and the "recheckpr" label. * Changed to simply call reusable workflows in asterisk-ci-actions. * Changed to use better concurrency groups. * The OnPRCPCheck and OnPRMergeApproved workflows were also... * Changed to simply call reusable workflows in asterisk-ci-actions. * Changed to use better concurrency groups. * The NightlyTest and CreateDocs were also tweaked	2 months ago

George Joseph	d558818ec1	res_stir_shaken: Allow missing or anonymous CID to continue to the dialplan. The verification check for missing or anonymous callerid was happening before the endpoint's profile was retrieved which meant that the failure_action parameter wasn't available. Therefore, if verification was enabled and there was no callerid or it was "anonymous", the call was immediately terminated instead of giving the dialplan the ability to decide what to do with the call. * The callerid check now happens after the verification context is created and the endpoint's stir_shaken_profile is available. * The check now processes the callerid failure just as it does for other verification failures and respects the failure_action parameter. If set to "continue" or "continue_return_reason", `STIR_SHAKEN(0,verify_result)` in the dialplan will return "invalid_or_no_callerid". * If the endpoint's failure_action is "reject_request", the call will be rejected with `433 "Anonymity Disallowed"`. * If the endpoint's failure_action is "continue_return_reason", the call will continue but a `Reason: STIR; cause=433; text="Anonymity Disallowed"` header will be added to the next provisional or final response.

George Joseph	3e74da3224	resource_channels.c: Fix memory leak in ast_ari_channels_external_media. Between ast_ari_channels_external_media(), external_media_rtp_udp(), and external_media_audiosocket_tcp(), the `variables` structure being passed around wasn't being cleaned up properly when there was a failure. * In ast_ari_channels_external_media(), the `variables` structure is now defined with RAII_VAR to ensure it always gets cleaned up. * The ast_variables_destroy() call was removed from external_media_rtp_udp(). * The ast_variables_destroy() call was removed from external_media_audiosocket_tcp(), its `endpoint` allocation was changed to to use ast_asprintf() as external_media_rtp_udp() does, and it now returns an error on failure. * ast_ari_channels_external_media() now checks the new return code from external_media_audiosocket_tcp() and sets the appropriate error response.

Holger Hans Peter Freyther	9fc631d028	ari/pjsip: Make it possible to control transfers through ARI Introduce a ChannelTransfer event and the ability to notify progress to ARI. Implement emitting this event from the PJSIP channel instead of handling the transfer in Asterisk when configured. Introduce a dialplan function to the PJSIP channel to switch between the "core" and "ari-only" behavior. UserNote: Call transfers on the PJSIP channel can now be controlled by ARI. This can be enabled by using the PJSIP_TRANSFER_HANDLING(ari-only) dialplan function.	2 months ago

George Joseph	453ddfce19	docs: Add version information to AGI command XML elements. This process was a bit different than the others because everything is in the same file, there's an array that contains the command names and their handler functions, and the last command was created over 15 years ago. * Dump a `git blame` of res/res_agi.c from BEFORE the handle_* prototypes were changed. * Create a command <> handler function xref by parsing the the agi_command array. * For each entry, grep the function definition line "static int handle_" from the git blame output and capture the commit. This will be the commit the command was created in. Do a `git tag --contains <commit> \| sort -V \| head -1` to get the tag the function was created in. * Add a single since/version element to the command XML. Multiple versions aren't supported here because the branching and tagging scheme changed several times in the 2000's.	3 months ago

George Joseph	db8ae1912d	res_pjsip_authenticator_digest: Make correct error messages appear again. When an incoming request can't be matched to an endpoint, the "artificial" auth object is used to create a challenge to return in a 401 response and we emit a "No matching endpoint found" log message. If the client then responds with an Authorization header but the request still can't be matched to an endpoint, the verification will fail and, as before, we'll create a challenge to return in a 401 response and we emit a "No matching endpoint found" log message. HOWEVER, because there WAS an Authorization header and it failed verification, we should have also been emitting a "Failed to authenticate" log message but weren't because there was a check that short-circuited that it if the artificial auth was used. Since many admins use the "Failed to authenticate" message with log parsers like fail2ban, those attempts were not being recognized as suspicious. Changes: * digest_check_auth() now always emits the "Failed to authenticate" log message if verification of an Authorization header failed even if the artificial auth was used. * The verification logic was refactored to be clearer about the handling of the return codes from verify(). * Comments were added clarify what return codes digest_check_auth() should return to the distributor and the implications of changing them.

George Joseph	32e6a30952	res_pjsip: Fix startup/reload memory leak in config_auth. An issue in config_auth.c:ast_sip_auth_digest_algorithms_vector_init() was causing double allocations for the two supported_algorithms vectors to the tune of 915 bytes. The leak only happens on startup and when a reload is done and doesn't get bigger with the number of auth objects defined. * Pre-initialized the two vectors in config_auth:auth_alloc(). * Removed the allocations in ast_sip_auth_digest_algorithms_vector_init(). * Added a note to the doc for ast_sip_auth_digest_algorithms_vector_init() noting that the vector passed in should be initialized and empty. * Simplified the create_artificial_auth() function in pjsip_distributor. * Set the vector initialization count to 0 in config_global:global_apply().	3 months ago

We have at least 1 source file with multiple DOCUMENTATION blocks so only the first one in them was being processed. The awk script was changed to continue searching rather than exiting after the first block. * Fixing the awk script revealed an issue in logger.c where the third DOCUMENTATION block contained a XML fragment that consisted only of a managerEventInstance element that wasn't wrapped in a managerEvent element. Since logger_doc.xml already existed, the remaining fragments in logger.c were moved to it and properly organized.	3 months ago

George Joseph	316693ded9	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.	3 months ago
George Joseph	ff0fb401ae	res_pjsip_authenticator_digest: Fix issue with missing auth and DONT_OPTIMIZE The return code fom digest_check_auth wasn't explicitly being initialized. The return code also wasn't explicitly set to CHALLENGE when challenges were sent. When optimization was turned off (DONT_OPTIMIZE), the compiler was setting it to "0"(CHALLENGE) which worked fine. However, with optimization turned on, it was setting it to "1" (SUCCESS) so if there was no incoming Authorization header, the function was returning SUCCESS to the distributor allowing the request to incorrectly succeed. The return code is now initialized correctly and is now explicitly set to CHALLENGE when we send challenges.	3 months ago
Naveen Albert	cd97f4069d	ast_tls_cert: Add option to skip passphrase for CA private key. Currently, the ast_tls_cert file is hardcoded to use the -des3 option for 3DES encryption, and the script needs to be manually modified to not require a passphrase.

Naveen Albert	f6e1c163bb	chan_iax2: Avoid unnecessarily backlogging non-voice frames. Currently, when receiving an unauthenticated call, we keep track of the negotiated format in the chosenformat, which allows us to later create the channel using the right format. However, this was not done for authenticated calls. This meant that in certain circumstances, if we had not yet received a voice frame from the peer, only certain other types of frames (e.g. text), there were no variables containing the appropriate frame. This led to problems in the jitterbuffer callback where we unnecessarily bailed out of retrieving a frame from the jitterbuffer. This was logic intentionally added in commit `73103bdcd5` in response to an earlier regression, and while this prevents crashes, it also backlogs legitimate frames unnecessarily. The abort logic was initially added because at this point in the code, we did not have the negotiated format available to us. However, it should always be available to us as a last resort in chosenformat, so we now pull it from there if needed. This allows us to process frames the jitterbuffer even if voicefmt and peerfmt aren't set and still avoid the crash. The failsafe logic is retained, but now it shouldn't be triggered anymore.
