2013-11-29Rename reconnect_timer -> connect_timerAnders Svensson
The former was misleading since the timer only applies to initial connection attempts, reconnection attempts being governed by watchdog_timer. The name is a historic remnant from a (dark, pre-OTP) time in which RFC 3539 was followed less slavishly than it is now, and the timer actually did apply to reconnection attempts. Note that connect_timer corresponds to RFC 6733 Tc, while watchdog_timer corresponds to RFC 3539 TwInit. The latter RFC makes clear that TwInit should apply to reconnection attempts. It's less clear if only RFC 6733 is read. Note also that reconnect_timer is still accepted for backwards compatibility. It would be possible to add an option to make reconnect_timer behave strictly as the name suggests (ie. ignore RFC 3539 and interpret RFC 6733 at face value; something that has some value for testing at least) but no such option is implemented in this commit.

To accept any nested list of codepoints and binaries. A list containing a binary was previously misinterpreted and the documentation was incomplete. Also, rework codec suite slightly to be able to specify values for which decode o encode is the identity map, for which encode should succeed, and for which encode should fail.

2013-06-10Let diameter_{tcp,sctp} be configured with permissible remote addressesAnders Svensson
Option 'accept' allows remote addresses to be configured as tuples or regular expressions. The remote addresses for any incoming (aka accepted) connection/association are matched against the configured values, any non-matching address causing the connection/association to be aborted.

* anders/diameter/5xxx_failed_avp/OTP-11092: Fix setting of Failed-AVP on {answer_message, 5xxx} from handle_request
2013-06-02Fix setting of Failed-AVP on {answer_message, 5xxx} from handle_requestAnders Svensson
RFC 6733 says that certain 5xxx result codes must be accompanied by Failed-AVP, and decode populates #diameter_packet.errors with Result-Code/AVP pairs for errors it detects. However, Failed-AVP was not set in the outgoing answer if the handle_request callback returned {answer_message, 5xxx}. It is now set with the AVP from the first pair with the specified Result-Code, if found. Note that {answer_message, 5xxx} doesn't handle all cases in which a 5xxx answer is required, only that in which the setting above is appropriate. If it isn't then handle_request should construct its answer and return {reply, Ans}.
2013-06-02Respect Host-IP-Address configurationAnders Svensson
Addresses returned from a transport module were always used to populate Host-IP-Address AVP's in an outgoing CER/CEA, which precluded the sending of a VIP address. Transport addresses are now only used if Host-IP-Address is unspecified. In other words, respect any configured Host-IP-Address, regardless of the physical addresses returned by the transport. To use the physical addresses, don't configure Host-IP-Address.

2013-04-11Make explicit local address to diameter_tcp:start/3 optionalAnders Svensson
Use the default address address (as selected by gen_tcp) if none is configured, passing it in the new 'connected' message introduced by the previous commit. The corresponding update to diameter_sctp has to wait until problems with inet:sockname/1 are resolved: the function currently only returns one address, and sometimes {0,0,0,0}. See OTP-11018.
2013-04-11Add transport interface 'connected' message with local address listAnders Svensson
A transport module can return a local address list from its start/3 function in order to specify addresses to be used as Host-IP-Address during capabilities exchange. Now allow addresses to be communicated in a 'connected' message in the case of a connecting transport, so that diameter_tcp (in particular) can make local address configuration optional, communicating the gen_tcp default after connection establishment instead.

2013-02-17Answer 5xxx errors with application_opt() request_errors = answerAnders Svensson
RFC 3588 allowed only 3xxx result codes in an answer-message (that is, an answer that sets the E-bit) while RFC 6733 also allows 5xxx result codes. Setting request_errors = answer tells diameter to answer 5xxx errors itself. Returning {answer_message, integer()} from a handle_request callback allows both 3xxx and 5xxx result codes to be set. {protocol_error, integer()} is retained for 3xxx result codes.
2013-02-16Be less brutal in setting Result-Code/Failed-AVPAnders Svensson
When receiving a request for which errors have been detected during decode, diameter previously used the errors list in the decoded diameter_packet record to unconditionally set Result-Code and Failed-AVP in the outgoing answer. It wasn't particularly delicate in doing so however and would happily set a 5xxx Result-Code even if a handle_request callback returned an answer-message, leading to an encode error. This behaviour became even less endearing as of commit ac452e28, which made it possible to handle_request to take place even for protocol errors. (ie. When a callback typically should return an answer-message.) This commit fixes the behaviour by only setting a value that's appropriate for the answer in question, either a 3xxx or a 5xxx, depending on if the answer's an answer-message or not. It also allows handle_request to prevent diameter from setting anything by setting errors = false in a returned diameter_packet. Ideally it should have been errors = [] but the empty list is the default value for the errors field and changing the default (ideally there shouldn't have been one) would require recompilation of all modules including diameter.hrl: choose the less attractive 'false' to avoid such backwards incompatibility. The request reception is also refactored somewhat to shorten some call chains.
2013-02-16Add application_opt() request_errorsAnders Svensson
Configuring the value 'callback' all errors detected in incoming requests to result in a handle_request callback. The default value 'answer_3xxx' is the previous behaviour in which diameter answers protocol errors without a callback.
2013-02-11Add transport_opt() length_errorsAnders Svensson
The value determines whether or not an unexpected message length in the header of an incoming messages causes the peer process to exit, the message to be discarded or handled as usual. The latter may only be appropriate for message-oriented transport (eg. SCTP) since stream-oriented transport (eg. TCP) may not be able to recover the message boundary once a length error has occurred.
2013-02-10Simplify and document diameter_tcp fragment timerAnders Svensson
Don't start a new timer with each incoming message. Instead, start a timer at timeout and flush after two successive timeouts with no message reception.
