* anders/diameter/reg/OTP-14839: Fix diameter_reg:subscribe/2 remove notification
2018-03-05Update appup for 20.3Anders Svensson
2018-03-05Fix inaccurate commentAnders Svensson
A peer_fsm process can be started long before a connection is established in the listening case. The time reported in a 'peer' tuple in service_info is of connection establishment.
2018-02-01Fix handling of SUSPECT connections at service terminationAnders Svensson
A peer connection in watchdog state SUSPECT is represented by a peer table entry in diameter_service, but not by a request table entry in diameter_peer, so diameter_service:terminate/2 could result in failures like this: exception error: no match of right hand side value [] in function diameter_traffic:peer_down/1 (base/diameter_traffic.erl, line 141) in call from lists:foldl/3 (lists.erl, line 1263) in call from ets:do_foldl/4 (ets.erl, line 611) in call from ets:foldl/3 (ets.erl, line 600) in call from diameter_service:terminate/2 (base/diameter_service.erl, line 557) in call from gen_server:try_terminate/3 (gen_server.erl, line 648) in call from gen_server:terminate/10 (gen_server.erl, line 833) in call from gen_server:handle_msg/6 (gen_server.erl, line 679)
2017-12-15Fix diameter_reg:subscribe/2 remove notificationAnders Svensson
Commit fae8ca0c broke notification by removing table elements before matching for them, causing diameter_tcp/sctp listening processes to live on after diameter:remove_transport/2. Commit 58091992 added diameter_reg:subscribe/2, and commit 5ca5fb71 started using it for listener exit.
2017-12-04Update appup for 20.2Anders Svensson
Only change is doc.
2017-10-25Merge branch 'anders/diameter/decode/OTP-14684' into maint-20Erlang/OTP
* anders/diameter/decode/OTP-14684: vsn -> 2.1.2 Update appup for ERIERL-14684
2017-10-14Fix error handling when decoding an AVP with an alternate dictionaryAnders Svensson
The options map wasn't updated after the AVP was identified, with the resulting consequences for M-bit interpretation.
2017-10-13Remove unused function argumentsAnders Svensson
Which may have been used in the past, but aren't now.
2017-10-13Fix faulty recursionAnders Svensson
The wrong variable was passed into the decode recursion, causing the options map to be contaminated by strict_mbit and failed_avp modifications that should only apply to component AVPs in the Grouped case. Decode errors and M-bits could be ignored as a result.
2017-10-13Update appup for ERIERL-14684Anders Svensson
2017-10-05Update appup and code_change for ERIERL-83Anders Svensson
2017-10-05Fix missing monitor in diameter_regAnders Svensson
Commit fae8ca0c inadvertently removed the monitor at add/1 and add_new/1. As a result, process death did not remove associations, causing table diameter_reg to leak entries and stop/start of a service to fail. Add a testcase to detect the problem, which existing testcases miss.

* anders/diameter/performance/OTP-14521: Fix append of Route-Record AVPs
2017-09-17Make unordered delivery configurableAnders Svensson
Changing the default in the parent commit is possibly a bit dangerous, even if the motivation still holds. Take a step back and make unordered delivery a matter of configuration, without changing the default: configuration is {unordered, boolean() | pos_integer()}, with false the default, and N equivalent to OS =< N, where OS is the number of outbound streams negotiated on the association in question. A user can mess with this by configuring an sctp_default_send_param of their own, but unordered sending is them from start, not only after the second message reception.
2017-09-15Fix append of Route-Record AVPsAnders Svensson
Commit b3d9e0c0 did away with the reordering of diameter_avp lists, so prepending the AVP to the list means prepending it in the message, which is not what the RFC requires. Appending to a list isn't ideal, but right now there's no better way.

2017-09-13Merge branch 'anders/diameter/grouped_decode/OTP-14607' into maintAnders Svensson
* anders/diameter/grouped_decode/OTP-14607: Fix diameter_packet.avps decode of Grouped AVP errors in Failed-AVP
2017-09-13Merge branch 'anders/diameter/DOIC/OTP-14588' into maintAnders Svensson
* anders/diameter/DOIC/OTP-14588: Fix avp_dictionaries decode with {decode_format, none}
2017-09-11Fix diameter_packet.avps decode of Grouped AVP errors in Failed-AVPAnders Svensson
The decode didn't respect the format as a list of diameter_avp records, so information about faulty component AVPs was lost.
2017-09-11Fix avp_dictionaries decode with {decode_format, none}Anders Svensson
Decode is only a no-op when the AVP is Grouped, and then only on the Grouped AVP itself, not its components.
2017-09-09Merge branch 'anders/diameter/config_consistency/OTP-14555' into maintAnders Svensson
* anders/diameter/config_consistency/OTP-14555: Fix type spec Fix strict_arities blunder
2017-09-09Merge branch 'anders/diameter/performance/OTP-14521' into maintAnders Svensson
* anders/diameter/performance/OTP-14521: Simplify implementation in diameter_reg (take 2)
2017-09-08Fix type specAnders Svensson
Map key was not retained when the spec was added in commit 66bb5251.
2017-09-08Fix strict_arities blunderAnders Svensson
The watchdog process retained the configuration, causing DWR/DWA encode to fail on a string-valued Origin-Host/Realm if the encode arity was relaxed. Bungled in commit 5f3becad.
2017-09-07Simplify implementation in diameter_reg (take 2)Anders Svensson
Simplify the simplification. The order of sending is changed, but the order isn't significant.

2017-09-06Fix type specAnders Svensson
That dialyzer hasn't noticed is wrong.

2017-09-05Fix minor monitor blunder in diameter_regAnders Svensson
Commit 58091992 discarded a new monitor reference, so didn't avoid multiple monitors as was the intention. The blunder was harmless since all but the first DOWN message resulted in notifications.
2017-09-04Let generic AVPs be encoded/decoded in alternate dictionariesAnders Svensson
To support specifications like RFC 7683 DOIC, that only define AVPs, not applications. AVPs that aren't known to the application dictionary in question could previously not be decoded. Configuring alternate dictionaries with the new transport/service option avp_dictionaries changes this, so that AVPs like DOIC's Grouped OC-OLR can presented in their fully decoded glory. Encode is also extended, allowing things like the following to be encoded in an outgoing message: 'AVP' => [{'OC-OLR', #{'OC-Sequence-Number' => 1, 'OC-Report-Type' => 0, 'OC-Reduction-Percentage' => [25]}}] A diameter_gen_doic_rfc7683 dictionary is installed, but avp_dictionaries isn't specific to DOIC. This commit also solves the problem demonstrated a few commits back, that application AVPs aren't decoded in answers setting the E-bit. Test coverage will come in a subsequent commit.
2017-09-04Rename field in codec map: dictionary -> app_dictionaryAnders Svensson
To better reflect what the field is: field 'module' is the dictionary module that's calling diameter_gen to decode a list of AVP, while field 'app_dictionary' is the dictionary module defining the message being decoded.
2017-09-04Add RFC 7683 Diameter Overload Indicator Conveyance text and dictionaryAnders Svensson
Which motivates the avp_dictionaries config that will be added in a subsequent commit.
2017-09-04Fix decode undefAnders Svensson
Function avp/5 isn't exported from dictionary modules. Not necessarily intentional, but don't just export it since that requires recompilation of all dictionary modules, since the function is in diameter_gen.hrl. Not having to recompile was the main motivation for moving most of the included code to module diameter_gen in commit 205521d3. This reveals a weakness in the decode of answers setting the E-bit: any AVP that isn't defined by the common application won't be decoded; the diameter_avp records that these are packed into (in the 'AVP' field of a message record, or equivalent) will have value = undefined. This is nothing new (same in OTP 19), but the values should be decoded. Fix it (and the lack of test coverage) in a subsequent commit that will add avp_dictionaries config.
2017-09-04Fix dictionary compilation error messageAnders Svensson
Adding a second {Vendor-Id} to the common CER definition results in this error: ** AVP CER at line 85 already referenced at line 84 That is, the error incorrectly refers to the message name (CER) where the AVP name (Vendor-Id) is expected.

2017-09-01Rename decode_format false to noneAnders Svensson
Which reads better and makes it easier to distinguish this false from others.
2017-09-01Tweak {decode_format, false} semanticsAnders Svensson
Represent the decoded message by its atom-valued name in diameter_packet.msg, which makes trace much more readable. A diameter_avp.value is untouched (ie. undefined): the AVP name is already in the name field.
