* Fix queue_clear replaced by queue_free errorNicolas Dufresne2018-06-182-2/+4
| | | | | | | | | There was two cases where instead of freeing the queue, we actually clear the queue so it's ready for reused. Notably in nice_socket_free_send_queue(), a missed name function and nicesrc element state change. This regression was introduced by: fa783b1dd727a6ee2b99a111ca24790ae850c2f7

| | | | | | | | | Setting writable socket callbacks doesn't have to be limited to reliable agents. TCP sockets need the callback in any case for correct operation and calling nice_socket_set_writable_callback() on a NiceSocket that has UDP as its base has no effect.

* discovery: ignore bogus Skype for Business srflx addressesJakub Adam2018-03-231-10/+21
| | | | | | | | | | | | | | | If main SfB TURN server sends our allocation request to an alternate server, the response will have XOR_MAPPED_ADDRESS containing the IP address of the turn server that proxied the message instead of our own actual external IP. Before we create server reflexive candidates upon receiving an allocate response, check that the TURN port got assigned on the same server we sent out allocate request to. Otherwise, the request was proxied and XOR_MAPPED_ADDRESS contains a bogus value we should ignore. Issue introduced by 59fcf95d505c3995f858b826d10cd48321ed383e.

* agent: make candidate username and password immutableFabrice Bellet2018-03-231-6/+13
| | | | | | | | | | | | | | | With this patch we prevent the username and the password of a candidate to be modified during a session, as required by the RFC, sect 9.1.2. This is also needed from a memory management point of view, because the password string pointer may be recorded in the components stun agent sent_ids[] struct key member, and freeing these values there may cause an use-after-free condition, when an inbound stun is received from this candidate. This behavior has been observed with pidgin, xmpp, and farstream when a same remote candidates are "updated" several times, even if the credentials don't change in this case.

* conncheck: rework early stun requests handlingFabrice Bellet2018-03-233-145/+66
| | | | | | | | | | | | | | | | | | | | | | With this patch we simplify the code used to handle the incoming stun request when remote candidates or remote credentials have not been received yet. When the remote credentials is unknown, the stun request is stored in a list of incoming_checks for later processing, and no further processing is done, except responding to the request. When the remote credentials are received, the triggered checks for these incoming checks can now be queued, and the related pairs are created. If the remote candidates have not been received when the stun request on a valid local port arrives, a peer-reflexive remote candidate will be created. This candidate may need to be updated later when remote candidates are finally received, including candidate priority and foundation, and also related pairs.

* conncheck: handle alternate-server for turn relays differentlyYouness Alaoui2017-11-281-13/+43
| | | | | | | If a relay gives us an alternate-server, we need to cancel and reset every candidate discovery attempt that uses the same server, to avoid ending up with one component on one server and the other component on another server (causing relay candidates with mismatched foundations).
* discovery: Increase discovery_unsched_items whenever we restart a checkYouness Alaoui2017-11-281-0/+4
| | | | | | The discovery_unsched_items is decremented every time a DiscoveryCandidate goes from non-pending to pending. So if we restart a check by setting pending to FALSE, we should re-increase the discovery_unsched_items.

| | | | | | | | | The MS Office TURN servers will always return the MS_ALTERNATE_SERVER in allocation responses, and if they are not handled, we end up using the main turn server to send allocation requests that then get sent to the alternate server which will return the XOR_MAPPED_ADDRESS containing the IP address of the turn server that proxied the message instead of our own actual external IP.

* conncheck: forgot to put a pair in triggered check listFabrice Bellet2017-09-051-2/+4
| | | | | | | | | | When a new pair is created from an unknown remote candidate, it should be enqueue for a triggered check, to allow it to be marked as nominated on response arrival in priv_mark_pair_nominated(). Creating it in waiting state is not sufficient since the update in priv_mark_pair_nominated() from previous commits. Differential Revision: https://phabricator.freedesktop.org/D1763
* conncheck: update the state of triggered checks pairsFabrice Bellet2017-09-051-71/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With this patch, we fix an ambiguity of some parts of the spec, when the document refers to in-progress pairs, that also concern pairs in the triggered checks list. The first cast is in section 7.1.2.5, "Updating the Nominated Flag", when the in-progress pair will be nominated on response arrival. This is handled in function priv_mark_pair_nominated(), when a pair is put to the triggered check list in reaction to a matching inbound stun request. Such a pair in priv_mark_pair_nominated() will _always_ be in the triggered check list, from the previously called function priv_schedule_triggered_check(). The second case is in section 8.1.2, "Updating State" when an in-progress pair stops its retransmission when another pair of higher priority is already nominated. This is handled by function priv_prune_pending_checks(). Until now, pairs enqueued in the triggered check list move transiently to state waiting, according to 7.2.1.4. But this state causes wrong decisions in the two previous cases, because such pairs should in fact rather be considered "like in-progress", to avoid discarding them inadvertantly. This patch update the state of the triggered check list pairs to in-progress. It allows to remove exception handling cited above: the code is a bit more simple, and allows some refactoring in priv_mark_pair_nominated() between RFC and compatibility modes.

* conncheck: support several stun requests per pairFabrice Bellet2017-09-052-361/+361
| | | | | | | | | | | | This patch should improve the reliabily of the connection check by keeping the record of several simultaneous ongoing stun requests per pair. A new stun request on an in-progress pair typically is caused by in inbound stun request from the peer on this same pair. This is named "Triggered Checks" in the spec. When this situation arises, it is fair to handle these two stun requests simultaneously, the triggered check, and the initial ordinary check, since both can potentially succeed.
