[asterisk-bugs] [JIRA] (ASTERISK-28231) res_http_websocket: Not responding to Connection Close Frame (opcode 8)

[Jeremy Lainé (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-28231?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=245900#comment-245900 ] 

Jeremy Lainé commented on ASTERISK-28231:
-----------------------------------------

After some further investigation, there are other issues with the way Asterisk handles CLOSE opcodes:

- the payload which is returned to the calling code is garbage, as no unmasking is performed
- the iostream doesn't get closed

> Asterisk's WebSocket implementation does not seem to respond to opcode 8, meaning that a client client which tries to close the WebSocket cleanly ends up hanging.
> Quoting RFC 6455 section 5.5.1 Close:
> {quote}
>    If an endpoint receives a Close frame and did not previously send a
>    Close frame, the endpoint MUST send a Close frame in response.
> {quote}
> I can reproduce this 100% against Asterisk 16.0.1 using a trivial Python script.
> NOTE: it would probably be good to run the full autobahn test suite to shake out any other quirks: https://github.com/crossbario/autobahn-testsuite
