2017-08-31Fix handling of Proxy-Info in answers formulated by diameterAnders Svensson
RFC 6733 says this: 6.2. Diameter Answer Processing When a request is locally processed, the following procedures MUST be applied to create the associated answer, in addition to any additional procedures that MAY be discussed in the Diameter application defining the command: ... o Any Proxy-Info AVPs in the request MUST be added to the answer message, in the same order they were present in the request. This wasn't done when a handle_request callback returned a Result-Code in an 'answer-message' or protocol_error tuple, causing diameter itself to construct the answer message. This form of answer is just a convenience, since the callback can always return an answer that it constructs itself.
2017-08-31Fix extraction of Experimental-Result for counter keysAnders Svensson
The introduction of decode_format in commit 722fa415 (and then 55e65b26) meant the value was not necessarily the intended tuple.
2017-08-31Rename variableAnders Svensson
It's no longer the AVP name as of the parent commit, but the name of the field/member the value will be stored in. Typically the AVP name, but possibly 'AVP'.
2017-08-31Fix decode of too many generic AVPsAnders Svensson
That is, when the arity of an 'AVP' field has an upper bound. This shouldn't happen in practice, but if an AVP is known but its name not explicit in the message grammar then its count was confused with that of AVPs packed into the 'AVP' field.
2017-08-31Enumerate AVPs in diameter_avp.index (again)Anders Svensson
Commit 96cd627a changed the way the index field was used, but the enumeration is used in at least one known application (as a pointer from elements of diameter_packet.errors to elements of diameter_packet.avps) and the motivation for the change is questionable: the lookup that was avoided was unnecessary given that it was already performed in incrementing a counter. Revert to enumerating as before in the non-relay case, but not in the relay case since there's no corresponding usecase.

2017-08-30Make handling of match contexts stricterBjörn Gustavsson
beam_validator could fail issue a diagnostic when a register that was supposed to be a match context was not guaranteed to be a match context. The bug was in merging of types. Merging of a match context with another term would result in a match context. That is wrong. Merging should produce a more general type, not a narrower type. Also, the valid slots in two match contexts should be combined with 'band', not 'bor'.
2017-08-29Send unordered on all outbound diameter_sctp streamsAnders Svensson
There's no reason for sending ordered since request handling is concurrent: different processes handling incoming requests can't know in which order they were received on the transport, and different processes sending requests can't know the order in which they're sent.
2017-08-29Delay rotation of diameter_sctp outbound streamsAnders Svensson
For the same reason as unordered delivery is delayed in the grandparent commit. Delivery is ordered only within a stream, so until a second message is received from the peer, there's no guarantee that a second outgoing request won't be received before the initial capablities exchange message. Rotation begins upon reception of a second message from the peer, messages being sent on stream 0 until then.

2017-08-29Use unordered delivery on a lone outbound stream in diameter_sctpAnders Svensson
RFC 6733 say the below about head-of-line blocking and SCTP, the suggestion of unordered sending being new compared to the RFC 3588. Until now, all delivery in diameter_sctp has been ordered, and roundrobin over available streams unless the user passes a stream identifier in an outgoing diameter_packet record. This commit changes this to use unordered delivery when there's only a single outbound stream to choose from. The special case at capabilities exchange is handled by only starting to send unordered after the second message from the peer has been received. (First message after capabilities exchange, as the RFC probably means.) The special case at DPR isn't handled, since there's no knowing the order in which a peer will answer: a node that sends DPR while it has other requests outstanding can't expect that the latter will be answered before DPR, even if delivery is ordered since incoming requests are handled concurrently. If it wants a guarantee then it simply has to wait for answers before sending DPR. A user can force all delivery to be unordered by specifying {sctp_default_send_params, #sctp_sndrcvinfo{flags = [unordered]}} as a config option to diameter_sctp, but in this case there's no handling of a request being sent directly after CEA since there's no ordered flag to override the default. RFC 6733: 2.1.1. SCTP Guidelines Diameter messages SHOULD be mapped into SCTP streams in a way that avoids head-of-the-line (HOL) blocking. Among different ways of performing the mapping that fulfill this requirement it is RECOMMENDED that a Diameter node send every Diameter message (request or response) over stream zero with the unordered flag set. However, Diameter nodes MAY select and implement other design alternatives for avoiding HOL blocking such as using multiple streams with the unordered flag cleared (as originally instructed in RFC 3588). On the receiving side, a Diameter entity MUST be ready to receive Diameter messages over any stream, and it is free to return responses over a different stream. This way, both sides manage the available streams in the sending direction, independently of the streams chosen by the other side to send a particular Diameter message. These messages can be out-of-order and belong to different Diameter sessions. Out-of-order delivery has special concerns during a connection establishment and termination. When a connection is established, the responder side sends a CEA message and moves to R-Open state as specified in Section 5.6. If an application message is sent shortly after the CEA and delivered out-of-order, the initiator side, still in Wait-I-CEA state, will discard the application message and close the connection. In order to avoid this race condition, the receiver side SHOULD NOT use out-of-order delivery methods until the first message has been received from the initiator, proving that it has moved to I-Open state. To trigger such a message, the receiver side could send a DWR immediately after sending a CEA. Upon reception of the corresponding DWA, the receiver side should start using out-of- order delivery methods to counter the HOL blocking. Another race condition may occur when DPR and DPA messages are used. Both DPR and DPA are small in size; thus, they may be delivered to the peer faster than application messages when an out-of-order delivery mechanism is used. Therefore, it is possible that a DPR/DPA exchange completes while application messages are still in transit, resulting in a loss of these messages. An implementation could mitigate this race condition, for example, using timers, and wait for a short period of time for pending application level messages to arrive before proceeding to disconnect the transport connection. Eventually, lost messages are handled by the retransmission mechanism described in Section 5.5.4.

We start the port in the started process in order to get the messages in the correct place and also so that unloading the port driver does not kill the test process.

2017-08-28Fix influence of decode_format on service eventsAnders Svensson
Decoded CER/CEA messages are passed in events messages that can be subscribed to using diameter:subscribe/1. A configured decode_format was not reflected in these, messages always being passed as records. Clarify that strict_arities only applies to message callbacks.

Since these can make sense per peer. The remaining service-only options either belong there or make little sense being configured per transport.
2017-08-25Let a service configure default transport optionsAnders Svensson
Only a default spawn_opt has been possible to configure, but there's no reason why most others should need to be configured per transport. Those options that still only make sense on a transport are transport_module/config (because of the semantics of multiple values), applications/capabilities (since these override service options), and private (since it's only to allow user-specific options in a backwards compatible way).
