* xep-0084:Michael Vetter2019-12-181-0/+4
| | | | | | | | | | | | So far we removed the avatar feature only after a succesful retrive in avatar_request_item_by_id() before we are going to retrieve the actual image. We should remove it at every `/avatar barejid` call too so in case one retrieval was unsucessful that we can call it again. So far it seems like there is no other way to trigger getting the nodes except announcing that we support the avatar feature.

* Check for correct delay tag for muc timestampsMichael Vetter2019-11-133-19/+42
| | | | | | | | | | | | | https://github.com/profanity-im/profanity/issues/1190 had another issue: Sometimes servers send multiple </delay> and we just checked the first one we got and only used it if the 'from' attribute was fitting. However it could be that we actually wanted the second </delay> element and there the 'from' would have been right. So we need to loop through them until we get the one with the fitting 'from'.

* Fix stanza_get_child_by_name_and_ns() if no nameMichael Vetter2019-11-121-1/+3

* _handle_groupchat(): get correct origin-id stanzaMichael Vetter2019-11-083-2/+22
| | | | | | | | | | | | | | | | | | The problem is that in _handle_groupchat() we look for STANZA_NS_STABLE_ID which will result in origin-id or stanza-id. It seems like prosody servers send origin-id first, so this worked in all my tests. But actually we cannot be sure of the order. So far we stopped after the first element was found. I only found xmpp_stanza_get_child_by_ns() and xmpp_stanza_get_child_by_name() in libstrophe. But we need a combination of both. So I created stanza_get_child_by_name_and_ns() for Profanity. I need to remember to upstream this to libstrophe later (if they really don't have such a function). Fix https://github.com/profanity-im/profanity/issues/1223
* Don't override ProfMessage Id with origin-idMichael Vetter2019-10-312-19/+43
| | | | | | | | | | Profanity sends the same value for both. Other clients might not. Safe both since we could need them later. Once we implement Last Message Correction we will need the regular id. If we override it with origin-id and another client chooses to not use the same value for id and origin-id then we can't interpret the id sent with the LMC request correctly.
* omemo: Check stanza names when iterating nodesaszlig2019-10-291-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some clients (eg. PSI) are sending the stanzas delimited by whitespace text nodes, which will fail while looping through the <prekeys/> children and also print weird errors when iterating through the <list/> of devices. When debugging this, I was looking at the XML of Gajim and PSI and first was somehow confused why Profanity printed "OMEMO: received device without ID" while the XML looked identical (minus the actual IDs and the JIDs of course). However, Gajim was sending the XML without whitespace nodes in between and PSI did not, so for example the following (with the relevant whitespace nodes marked with X): <message type="headline" to="..." from="..."> <event xmlns="http://jabber.org/protocol/pubsub#event"> <items type="headline" node="eu.siacs.conversations.axolotl.devicelist"> <item id="..."> <list xmlns="eu.siacs.conversations.axolotl"> X <device id="..."/> X <device id="..."/> X </list> </item> </items> </event> <delay xmlns="urn:xmpp:delay" stamp="..." from="..."/> </message> ... would result in three times the "OMEMO: received device without ID" error, because we actually have three XML text nodes here that obviously don't have an "id" attribute. Now since the <list/> children above aren't really a problem and only annoying, text nodes in the <prekeys/> stanza actually cause omemo_start_device_session_handle_bundle to return failure. I've fixed this by explicitly matching the stanza names we are interested in, skipping everything else. Signed-off-by: aszlig <aszlig@nix.build> Reported-by: @devhell
* Set mucuser in carbon caseMichael Vetter2019-10-291-0/+8
| | | | | | | | | | | Also we initialize mucuser properly. Now in case of a carbon of a MUC PM we sv_ev_incoming_carbon() which calls _sv_ev_incoming_plain() and then we log it via chat_log_msg_in() in there. But we also get the sv_ev_incoming_private_message() and call chat_log_msg_in() in there too. So the incoming message get's logged twice.
* Make prof_identifier constMichael Vetter2019-10-221-1/+1

* Use UUID in origin-id and idMichael Vetter2019-10-222-11/+11
| | | | | Let's use UUID to have a more random string then just 10 alphanumeric values.
* Remove old commentMichael Vetter2019-10-211-1/+0
| | | | | It's not up to date. Some time ago we changed from individual handlers to general ones.
* Set prof_ident to NULL after freeMichael Vetter2019-10-211-1/+2
| | | | | | | | | | | | | | | | | | This caused the bug mentioned in the PR comment: ``` It seems with the changes done here we get a crash in: src/xmpp/message.c message_handlers_init() when looking up handlers: ProfMessageHandler *handler = g_hash_table_lookup(pubsub_event_handlers, curr->data);.

| | | | And move defintion to xmpp.h
* Add XEP-0359 to capabilitiesMichael Vetter2019-10-181-0/+1
| | | | | | | | | | | | | We implement </origin-id> from [XEP-0359](https://xmpp.org/extensions/xep-0359.html). We already had this implemented for OMEMO. And now use it to check whether MUC messages were sent from us (https://github.com/profanity-im/profanity/issues/1201). We don't implement </stanza-id> yet, but probably need to do so for MAM. Anyways let's flag this as implementing the XEP. Fix https://github.com/profanity-im/profanity/issues/1207

* Remove prefix from stanza idMichael Vetter2019-10-1710-64/+64
| | | | | We sent `prof_prefix_uuid` as id. Where the prefix was also optional. We don't need this at all.
* Change algo for connection_create_stanza_id()Michael Vetter2019-10-171-7/+11

* Change connection_create_stanza_id()Michael Vetter2019-10-171-11/+11
| | | | | To return identifier and uuid together. We can remove the prefix later on.
* Calculate identifier upon connectMichael Vetter2019-10-161-5/+28
| | | | | | | This will be needed so that we can later detect if messages (origin-in) was sent by us. Regards https://github.com/profanity-im/profanity/issues/1207
* Rename identification fileMichael Vetter2019-10-161-1/+2

* Use random string for random-bytes identifierMichael Vetter2019-10-161-4/+5
| | | | | | And rename `instance` to `identifier`. Regards https://github.com/profanity-im/profanity/issues/1207
* Move code from jid_random_resource() into own functionMichael Vetter2019-10-161-12/+4
| | | | | Move the code that creates a random string into it's own function +get_random_string().
* Create random-bytes fileMichael Vetter2019-10-161-0/+53
| | | | | | | | | | So far only with dummy value. We will need an identifier that we can hash together with a message ID and put in as the origin-id. So when we receive message we can unsplit it and see if it was sent from this client. Regards https://github.com/profanity-im/profanity/issues/1207
* Improve MUC 1:1 loggingMichael Vetter2019-10-072-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | If we get a private message from a user in a MUC profanity shows this like: `profanity@roomsASDF.dismail.de/Martin: Hi` This was so far logged at: `~/.local/share/profanity/chatlogs/my-account-at-server/profanity_at_rooms.dismail.de/2019_09_04.log` as: ``` 10:48:13 - profanity@rooms.dismail.de: Hi ``` So the nickname was not saved anywhere. This is due to us not knowing whether we got a regular message from user@server.org/resource or a MUC PM from room@server.org/user. We now check for `<x xmlns='http://jabber.org/protocol/muc#user' />` and add the resourcepart to the logging if we get it. The file will be created at `~/.local/share/profanity/chatlogs/my-account-at-server/profanity_at_rooms.dismail.de_nick` and look like: ``` 23:59:43 - nick: Hi ``` Fix https://github.com/profanity-im/profanity/issues/1184

* Detect MUC history correctly with some Prosody versionsMichael Vetter2019-09-301-1/+3
| | | | | | | | | | Some versions of prosody send the domainpart. See https://issues.prosody.im/1416 Workaround to handle those cases. Thanks to Holger Weiss for helping with this! Fix https://github.com/profanity-im/profanity/issues/1190

CVE-2019-16236: Is checking the from in roster pushes. We do that but didn't log it yet. CVE-2019-16237: Is checking the form in MAM messages. We don't support them yet.

* Don't render (all) delayed messages as MUC historyHolger Weiß2019-08-203-2/+20
| | | | | | | | Double-check that a <delay/> tag on a groupchat message was actually added by the MUC service (rather than the sending client) before assuming it was received from the MUC history. Fixes #1173.
