2015-08-04Fix relay encode of decoded diameter_avp listsAnders Svensson
Commit c74b593a fixed the problem that a decoded deep diameter_avp list couldn't be encoded, but did so in the wrong way: there's no need to reencode component AVPs since the Grouped AVP itself already contains the encoded binary. The blunder caused diameter_codec:pack_avp/1 to fail if the first element of the AVP list to be encoded was itself a list. Thanks to Andrzej TrawiƄski for reporting the problem.

* anders/diameter/sctp/OTP-12744: Fix diameter_sctp listener race Tweak transport suite failures Run traffic suite over SCTP
2015-05-24Fix diameter_sctp listener raceAnders Svensson
Commit 4b691d8d made it possible for accepting transport processes to be started concurrently, and commit 77c1b162 adapted diameter_sctp to this, but missed that the publication of the listener process in diameter_reg has to precede the return of its start function. As a result, concurrent starts could result in multiple listener processes.
2015-05-24Tweak transport suite failuresAnders Svensson
Make anything but a comm_up sctp_assoc_change crash. Make timeouts more reasonable.
2015-05-24Run traffic suite over SCTPAnders Svensson
Previously it was only run over TCP. Configure a pool of accepting processes since simultaneous connections are otherwise prone to rejection, as discussed in commit 4b691d8d. Tweak timeouts to more reasonable values.
2015-05-24Replace config suite call to erlang:now/0Anders Svensson
To remove a compilation warning with OTP 18.
2015-05-24Fix incorrect suite usage of OTP 18 monotonic timeAnders Svensson
Value was used as strictly increasing when it's only non-decreasing, causing testcases to fail.

2015-05-18Fix counting of no_result_code/invalid_error_bitAnders Svensson
The message was regarded as unknown if the answer message in question set the E-bit and the application dictionary was not the common dictionary.
2015-05-18Count relayed answersAnders Svensson
That is, outgoing answer messages received in response to a handle_request callback having returned {relay, Opts}.
2015-05-18Rename dictionary-related functions/variablesAnders Svensson
To clarify what it is that's being computed, which isn't entirely obvious. No functional change, just renaming.
2015-05-18Lift answer send up the call chainAnders Svensson
As the first step in starting to count outgoing, relayed answer messages.
2015-05-18Count discarded incoming messagesAnders Svensson
An incoming Diameter message is either a request, an answer to an outstanding request, or an unexpected answer. The latter weren't counted, but are now counted on keys of this form: {pid(), {{unknown, 0}, recv, discarded}} The form of the second element is similar to those of other counters, like: {{relay, 0|1}, send|recv, invalid_error_bit} Compare this to the key used when counting known answers: {{ApplicationId, CommandCode, 0}, recv} The application id and command code aren't included so as not to count on arbitrary keys, a topic last visited in commit 49e8b11c.
2015-05-18Include R-bit in unknown message counter keysAnders Svensson
To differentiate between requests and answers, in analogy with relay counters. This isn't backwards compatible, but these counters aren't yet documented.
2015-05-18Fix broken relay countersAnders Svensson
Commit 49e8b11c broke the counting of relayed message, causing them to be accumulated as unknown messages.
2015-05-18Fix broken result code countersAnders Svensson
Commit a1df50b3 broke result code counters in the case of answer messages sent as a header/avp lists (unless the avps, untypically, set the name field), and for answers sent/received in the relay application.
2015-05-17Add counters testcase to relay suiteAnders Svensson
Which fails for a variety of reasons to be addressed in subsequent commits.

* anders/diameter/result_codes/OTP-12654: Fix broken traffic testcase Match harder in traffic suite Don't confuse Result-Code and Experimental-Result
2015-05-05Fix broken traffic testcaseAnders Svensson
The send_error testcase tested that Session-Id in an answer-message was not undefined, but that's always the case since the AVP has arity 0 or 1. The correct test is that it's a list of length 1, to ensure that diameter has inserted the session id as expected.
2015-05-05Match harder in traffic suiteAnders Svensson
To ensure that the expected answer messages are received.
2015-05-05Don't confuse Result-Code and Experimental-ResultAnders Svensson
Decode of an answer message not setting the E-bit, and containing Experiment-Result but not Result-Code, identified Result-Code as the erroneous when Erroneous-Result-Code was 3xxx. Here's an example (from trace) of a the errors field after decode: [{5004, {diameter_avp,undefined,undefined,false,false,undefined,'Result-Code', 3001,undefined,undefined}}], The diameter_avp was just constructed from the AVP name and decoded result, without regard for which result code AVP contained the value. Fix by extracting the AVP from the incoming message.
2015-05-03Fix broken pre-17.4 appupAnders Svensson
Upgrade instructions have been added for each 17.X release without adjusting the instructions for preceeding releases: the instructions have only been sufficient to upgrading one release at a time: 17.0 to 17.1, 17.1 to 17.2, etc. Conficting load order requirements make smooth upgrade from an arbitrarily old release impossible. In this case, 17.3 looks to be as far back as we can go, so require restart from 17.[0-2] or older. Update the app suite to deal with binary regexps in appup, and to match version numbers harder.
2015-05-03Update appup for 17.5.3Anders Svensson

2015-05-03Add counters testcase to 3xxx suiteAnders Svensson
To start checking that the counters are counting what's expected. The parent commit fixes a case in which they weren't.
2015-05-03Fix counting error with unknown application idAnders Svensson
Statistics could be accumulated on a key like {{23,275,0}, recv} even though 23 was not the application id of the dictionary in question. Missed in commits df19c272 and 7816ab2f.

2015-04-03Remove extra avp bit from diameter_avp decodeAnders Svensson
In the case of a faulty AVP Length (pointing past the end of a message or not spanning the header), an extra bit is prepended to data bytes in diameter_avp:collect_avps/1 in order to force a 5014 decode error. The bit is supposed to be removed as part of the decode in diameter_gen.hrl but this didn't happen in case of an AVP that unknown to the dictionary in question.

2015-03-27Remove potentially large error reason in call to diameter_lib:log/4Anders Svensson
The function is intended to be traced on, to see abnormalities (mostly) without producing excessive output. In the case of decode failure, the error reason can be things like {badmatch, HugeBinary}. Missed in commit 0058430.
2015-03-27Limit FQDN in DiameterURI to 255 octetsAnders Svensson
As for the port number in the parent commit, a FQDN can't be arbitrarily long, at most 255 octets. Make decode fail if it's more.
2015-03-27Limit DiameterURI ports to 0-65535 digits on decodeAnders Svensson
A port number is a 16-bit integer, but the regexp used to parse it in commit 1590920 slavishly followed the RFC 6733 grammar in matching an arbitrary number of digits. Make decode fail if it's anything more than 5, to avoid doing erlang:list_to_integer/1 on arbitrarily large lists. Also make it fail if the resulting integer is outside of the expected range.
2015-03-27Add service_opt() incoming_maxlenAnders Svensson
To bound the length of incoming messages that will be decoded. A message longer than the specified number of bytes is discarded. An incoming_maxlen_exceeded counter is incremented to make note of the occurrence. The motivation is to prevent a sufficiently malicious peer from generating significant load by sending long messages with many AVPs for diameter to decode. The 24-bit message length header accomodates (16#FFFFFF - 20) div 12 = 1398099 Unsigned32 AVPs for example, which the current record-valued decode is too slow with in practice. A bound of 16#FFFF bytes allows for 5461 small AVPs, which is probably more than enough for the majority of applications, but the default is the full 16#FFFFFF.
2015-03-26Add guard to reject {spawn_opt, false} as transport/service_opt()Anders Svensson
It was possible to configure the option, but doing so caused the service to fail when starting a watchdog process: {function_clause, [{diameter_service,'-spawn_opts/1-lc$^0/1-0-', [false], [{file,"base/diameter_service.erl"},{line,846}]}, {diameter_service,start,5, [{file,"base/diameter_service.erl"},{line,820}]}, {diameter_service,start,3, [{file,"base/diameter_service.erl"},{line,782}]}, {diameter_service,handle_call,3, [{file,"base/diameter_service.erl"},{line,385}]}, {gen_server,try_handle_call,4,[{file,"gen_server.erl"},{line,607}]}, {gen_server,handle_msg,5,[{file,"gen_server.erl"},{line,639}]}, {proc_lib,init_p_do_apply,3,[{file,"proc_lib.erl"},{line,237}]}]} Tests for the option in the config suite were also missing. Bungled in commit 78b3dc6.

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.
