2011-11-10Accept any 2xxx result code in CEAAnders Svensson
2011-11-10Rename some functions plus comment tweakAnders Svensson
In diameter_service: make_packet -> make_request_packet make_header -> make_request_header make_reply_packet -> make_answer_packet
2011-11-10Send events for connection establishment failureAnders Svensson
If a peer fsm process exits then the exit reason is received by the service process in a 'DOWN' message. If the reason is the one generated by diameter_peer_fsm:close/2, which is called to signal a non-transport failure before the completion of capabilities exchange (eg. receiving an unsuccessful CEA), then an event is sent to any subscribers. Also, tweak capabilities_cb return values for more informative event data.
2011-11-10Add capabilities_cb transport optionAnders Svensson
Value is a function that's applied to the transport reference and capabilities record after capabilities exchange. If a callback returns anything but 'ok' then the connection is closed. In the case of an incoming CER, the callback can return a result code with which to answer. Multiple callbacks can be specified and are applied until either all return 'ok' or one doesn't. Also, include Origin-State-Id in answers where it was previously omitted.
2011-11-10Minor tls_ack simplificationAnders Svensson
We're already monitoring the transport process, no need to do so again.
2011-11-10Fix comment typoAnders Svensson
2011-11-09Minor dependency fixAnders Svensson
2011-10-19Dumb down release target to Solaris /usr/ucb/installAnders Svensson
2011-10-19Dumb down opt/release targets to make 3.80Anders Svensson
2011-10-19Minor tweaks and cleanupAnders Svensson
Tweak some comments and variable names, move things around a bit (default src target is now opt, not debug), only clean what's built, use +warn_export_vars.
2011-10-18Need absolute -pa for bootstrap buildAnders Svensson
Otherwise include_lib will fail.
2011-10-18Simpler release targets for src subdirectoriesAnders Svensson
2011-10-17Use secondary expansion for src subdirectory rulesAnders Svensson
Makes for a quieter rule with no recursion.
2011-10-17One makefile for src build instead of recursionAnders Svensson
Simpler, no duplication of similar makefiles and makes for better dependencies. (Aka, recursive make considered harmful.)
2011-10-17Remove app dependency on compiler to avoid forced recompilationAnders Svensson
2011-10-17Move diameter_exprecs to compiler directoryAnders Svensson
2011-10-17Add diameter_make as compilation interfaceAnders Svensson
As a module-based alternative to the escript diameterc.
2011-10-17Allow @inherits to be set/cleared with diametercAnders Svensson
This is to enable dictionaries compiled with --name/--prefix to be inherited using --inherits.
2011-10-17Allow @name/@prefix to be set with diametercAnders Svensson
2011-10-17Dependency fixAnders Svensson
Has to follow the release_targets include for make not to think that a misspelled dictionary is up to date just because the exprecs dependency is.
2011-10-17Move dictionaries into own directory and renameAnders Svensson
Generated files are unchanged but the separation will be especially pleasant when more dictionary files are added as examples. It is still only the rfc3588 and relay dictionaries that are known to the diameter implementation.
2011-10-17Whitespace fixesAnders Svensson
2011-10-17@result_code -> @define in dictionary filesAnders Svensson
The section simply results in generated macros and has nothing specifically to do with result codes. It's still not documented, and neither are the macros generated from @enum, since the generated names are typically so long as to be impractical/unreadable in source. Better to use numeric values with a comment or define your own shorter macros as the need arises.
2011-10-10Register tcp listener before transport start returnAnders Svensson
2011-10-10Add port resolution interface to transport modulesAnders Svensson
2011-10-06Add tls support at connection establishmentAnders Svensson
This is the method added in draft-ietf-dime-rfc3588bis, whereby a TLS handshake immediately follows connection establishment and CER/CEA is sent over the secured connection.
2011-10-06Close transport if tls is requested over sctpAnders Svensson
RFC 3588 requires that a Diameter server support TLS but in practise this seems to mean TLS over SCTP since there are limitations with running over SCTP: see RFC 6083 (DTLS over SCTP), which is a response to RFC 3436 (TLS over SCTP). The current RFC 3588 draft acknowledges this by equating the Inband-Security-Id value TLS with TLS/TCP and DTLS/SCTP but underlying support for DTLS is still thin on the ground.
2011-10-06Handle tls notification for tcpAnders Svensson
If TLS has been configured on Inband-Security-Id then the transport process receives a message from the peer_fsm process indicating whether or not to upgrade to TLS. The current draft of RFC 3588 deprecates (but retains for backwards compatibility) the use of Inband-Security-Id for negotiating TLS, adding the possibility of TLS having be negotiated before capabilities exchange. This commit handles the deprecated case.
2011-10-06Lift recursion in tcp message reception up the call chainAnders Svensson
When an initial message is received and TLS is a possibility, must wait for a message from the peer process before either commencing a handshake or receiving more messages.
2011-10-06Add tls support to capabilities exchangeAnders Svensson
To upgrade a connection to TLS or not, that is the question. It is possible for us to send a CER offering both NO_INBAND_SECURITY and TLS and for the peer to answer likewise: RFC 3588 doesn't make clear that a CEA should be unambiguous about the choice of security. Thus, if TLS is offered then assume the server is prepared to for a handshake. Similarly, when receiving a CER, choose TLS if it's offered and be unambiguous about our choice in CEA. There is no ssl:maybe_accept that would let us receive a handshake if it comes or another message if it doesn't. The choice of TLS should probably be made into a callback so that an application can decide based on the peer's Origin-Realm for example. Such a callback could also be used to reject a CER/CEA. Handle Inband-Security-Id values other than NO_INBAND_SECURITY and TLS by assuming that they require no intervention by the transport module, treating them like NO_INBAND_SECURITY. Whether or not this is reasonable (or useful) is unclear. There may be a need for more sychronization than we have on offer. (Having to do something before taking the connection up for example.) Note that diameter_peer_fsm must be upgraded before diameter_capx because of the new return value from diameter_capx:recv_CEA/2.

2011-09-26Fix bugs in sending of answer-message repliesAnders Svensson
3001 (DIAMETER_COMMAND_UNSUPPORTED) was not sent since the decode placed the AVP list in the errors field rather than the avps field of the diameter_packet, causing the subsequent encode to fail. Session-Id was also set improperly, causing encode to fail even in this case.
2011-09-26Fix and clarify relay behaviourAnders Svensson
Leave it up to a handle_request callback to decide whether or not to filter the peer from which the incoming request was sent. Reply with 3002 (DIAMETER_UNABLE_TO_DELIVER) on anything but an answer from the peer.
2011-09-26Makefile dependency fixAnders Svensson
Dependency of generated dictionary modules on diameter.hrl and diameter_gen.hrl was missed.
2011-09-26Use single format for error_logger reportsAnders Svensson
2011-09-26Fix sending of messages of arbitrary formAnders Svensson
diameter:call/4 can be passed anything, as long as the subsequent prepare_request callback returns a term that can be encoded.
2011-09-26Fix and clarify semantics of peer filtersAnders Svensson
An eval filter returning a non-true value caused the call process to fail and the doc was vague on how an exception was treated. Clarify that the non-tuple host/realm filters assume messages of a certain form. Various minor corrections to align code and doc.
2011-09-26Fix improper use of error_logger:info_report/2Anders Svensson
Function doesn't take a format string and arguments as we called it. Instead use error_logger:info_report/1 and use the same report format as used for warning and error reports.
2011-09-26Fix header folding bugAnders Svensson
A prepare_request callback from diameter can return a diameter_header record with in order to set values in the header of an outgoing request. The fault in diameter_lib:fold_tuple/3 caused encode of the outgoing request to fail.

2011-09-14Handle #sctp_paddr_change and #sctp_pdapi_event from gen_sctp.Anders Svensson
The events are enabled by default but diameter_sctp neither disabled nor dealt with them. Reception of such an event caused a transport process to crash.
