2015-03-24Adapt to changed DiameterURI defaults in RFC 6733Anders Svensson
Despite claims of full backwards compatibility, the text of RFC 6733 changes the interpretation of unspecified values in a DiameterURI. In particular, 3588 says that the default port and transport are 3868 and sctp respectively, while 6733 says it's either 3868/tcp (aaa) or 5658/tcp (aaas). The 3588 defaults were used regardless, but now use them only if the common dictionary is diameter_gen_base_rfc3588. The 6733 defaults are used otherwise. This kind of change in the standard can lead to interop problems, since a node has to know which RFC its peer is following to know that it will properly interpret missing URI components. Encode of a URI includes all components to avoid such confusion. That said, note that the defaults in the diameter_uri record have *not* been changed. This avoids breaking code that depends on them, but the risk is that such code sends inappropriate values. The record defaults may be changed in a future release, to force values to be explicitly specified.
2015-03-24Reject transport=udp;protocol=diameter at DiameterURI encodeAnders Svensson
Both RFC 3588 and 6733 disallow the combination. Make its encode fail.

2015-03-24Let examples override default service optionsAnders Svensson
To make them a bit more flexible. Can now do things like this: server:start([{'Product-Name', "Bob"}]), server:listen({tcp, [{capx_timeout, 2000}]}) Beware that the latter is completely different from this: server:listen(tcp, [{capx_timeout, 2000}])
2015-03-24Set {restrict_connections, false} in example serverAnders Svensson
Since there's no reason to reject a client that wants to establish multiple connections, given that diameter can handle it.
2015-03-24Set {string_decode, false} in examplesAnders Svensson
So as to do what's now recommended in diameter(1), in the grandparent commit.
2015-03-24Test {string_decode, false} in traffic suiteAnders Svensson
By adding string decode or not in the server or client as another combination. Run all traffic cases in parallel: remove the sequential tests. Common test seems unable to deal with {group, X, [parallel]} within a group.
2015-03-24Add service_opt() string_decodeAnders Svensson
To control whether stringish Diameter types are decoded to string or left as binary. The motivation is the same as in the parent commit: to avoid large strings being copied when incoming Diameter messages are passed between processes; or *if* in the case of messages destined for handle_request and handle_answer callbacks, since these are decoded in the dedicated processes that the callbacks take place in. It would be possible to do something about other messages without requiring an option, but disabling the decode is the most effective. The value is a boolean(), true being the default for backwards compatibility. Setting false causes both diameter_caps records and decoded messages to contain binary() in relevant places that previously had string(): diameter_app(3) callbacks need to be prepared for the change. The Diameter types affected are OctetString and the derived types that can contain arbitrarily large values: OctetString, UTF8String, DiameterIdentity, DiameterURI, IPFilterRule, and QoSFilterRule. Time and Address are unaffected. The DiameterURI decode has been redone using re(3), which both simplifies and does away with a vulnerability resulting from the conversion of arbitrary strings to atom. The solution continues the use and abuse of the process dictionary for encode/decode purposes, last seen in commit 0f9cdba.

2015-03-23Fix problem with invalid timeouts because of truncated floatsPeter Andersson
2015-03-23Strip potentially large terms when sending outgoing Diameter messagesAnders Svensson
Both incoming and outgoing Diameter messages pass through two or three processes, depending on whether they're incoming or outgoing: the transport process and corresponding peer_fsm process and (for incoming) watchdog processes. Since terms other than binary are copied when passing process boundaries, large terms lead to copying that can be problematic, if frequent enough. Since only the bin and transport_data fields of a diameter_packet record are needed by the transport process, discard others when sending outgoing messages. Strictly speaking, the statement that only the aforementioned fields are needed by the transport process depends on the transport process. It's true of those implemented by diameter (in diameter_tcp and diameter_sctp), but an implementation that makes use of other fields is assuming more than the documentation in diameter_transport(3) promises.

2015-03-23Discard incoming/outgoing requests after incoming DPRAnders Svensson
With the same motivation as in commits 5bd2d72 and b1fd629. As in the latter, incoming DPR is the only exception.
2015-03-23Add transport_opt() dpr_timeoutAnders Svensson
To cause a peer connection to be closed following an outgoing DPA, in case the peer fails to do so. It is the recipient of DPA that should close the connection according to RFC 6733.
2015-03-23Be lenient with errors in incoming DPRAnders Svensson
To avoid having the peer interpret the error as meaning the connection shouldn't be closed, which probably does more harm than ignoring syntactic errors in the DPR. Note that RFC 6733 says this about incoming DPR, in 5.4 Disconnecting Peer Connections: Upon receipt of the message, the Disconnect-Peer-Answer message is returned, which SHOULD contain an error if messages have recently been forwarded, and are likely in flight, which would otherwise cause a race condition. The race here is presumably between answers to forwarded requests and the outgoing DPA, but we have no handling for this: whether or not there are pending answers is irrelevant to how DPR is answered. It's questionable that a peer should be able to prevent disconnection in any case: it has to be the node sending DPR that decides if it's approriate, and the peer should take it as an indication of what's coming. Incoming DPA is already treated leniently: the only error that's not ignored is mismatching End-to-End and Hop-by-Hop Identifiers, since there's no distinguishing an erroneous value from an unsolicited DPA. This mismatch could also be ignored, which is the case for DWA for example, but this problem is already dealt with by dpa_timeout, which causes a connection to be closed even when the expected DPA isn't received.

2015-03-23Fix ordering of AVPs in relayed messagesAnders Svensson
6.1.9 of RFC 6733 states this: A relay or proxy agent MUST append a Route-Record AVP to all requests forwarded. The AVP was inserted as the head of the AVP list, not appended, since the entire AVP list was reversed relative to the received order. Thanks to Andrzej Trawiński.
2015-03-22Discard CER or DWR sent with diameter:call/4Anders Svensson
These are requests that diameter itself sends. It's previously been possible to send them, but answers timed out at the caller since they were discarded in diameter_watchdog. Answers will still timeout, but now the requests are discarded before being sent.
2015-03-22Allow DPR to be sent with diameter:call/4Anders Svensson
DPR is sent by diameter at application shutdown, service stop, or transport removal. It has been possible to send the request with diameter:call/4, but the answer was discarded, instead of the transport process being terminated. This commit causes DPR to be handled in the same way regardless of whether it's sent by diameter or by diameter:call/4. Note that the behaviour subsequent to DPA is unchanged. In particular, in the connecting case, the closed connection will be reestablished after a connect_timer expiry unless the transport is removed. The more probable use case is the listening case, to disconnect a single peer associated with a listening transport.
2015-03-22Add transport_opt() dpa_timeoutAnders Svensson
To make the default DPA timeout configurable. The timeout say how many milliseconds to wait for DPA in response to an outgoing DPR before terminating the transport process regardless.
2015-03-22Add testcase for sending DPR with diameter:call/4Anders Svensson
That currently fails when the resulting DPA is regarded as unsolicited in diameter_peer_fsm, causing the request to timeout at the caller.
2015-03-22Discard incoming requests after outgoing DPRAnders Svensson
Since there's a race between an answer being sent and the connection being closed upon the reception of DPA that's likely to be lost, and because of the questionability of sending messages after DPR, as discussed in the parent commit. An exception is made for DPR so that simultaneous DPR in both directions doesn't result in it being discarded on both ends.
2015-03-22Discard outgoing requests after outgoing DPRAnders Svensson
RFC 6733 isn't terribly clear about what should happen to incoming or outgoing messages once DPR is sent and the Peer State Machine transitions into state Closing. There's no event for this in section 5.6, Peer State Machine, and no clarification in section 5.4, Disconnecting Peer Connections. There is a little bit of discussion in 2.1.1, SCTP Guidelines, in relation to unordered message delivery, but the tone there is that messages might be received after DPR because of unordered delivery, not because they were actually sent after DPR. Discarding outgoing answers may do more harm than good, but requests are more likely to be unexpected, as has been seen to be the case with DWR following DPR. DPR indicates a desire to close the connection: discard any subsequent outgoing requests.
