'raimo/kernel/inet_ntoa_1-IPv6-lowercase/ERIERL-20/ERL-429/OTP-13006' * raimo/kernel/inet_ntoa_1-IPv6-lowercase/ERIERL-20/ERL-429/OTP-13006: Accept IPv6 address %suffixes when parsing Adjust inet:ntoa/1 to RFC5952, but not deeper Update inet:ntoa according to modern RFCs
2017-06-12Accept IPv6 address %suffixes when parsingRaimo Niskanen
This only implements decimal suffixes, and furthermore only with a leading "0". A complete implementation would probably allow one and probably two digit suffixes without. But what primarily is missing is translating interface names to and from interface indexes. This also only implements the parsing, and uses the FreeBSD trick of squeezing in the Scope Id in the second 16-bit word of the fe80::/64 or ff02:/64 address prefix. But inet_drv is not prepared to handle this word, so it might only work on FreeBSD, not being supported even there... So inet_drv needs to handle this too.
2017-06-11Make diameter_{tcp,sctp} sender configurableAnders Svensson
With sends still from the receiving process by default, since changing the default behaviour may well have negative effects. A separate sender probably implies a greater need for some form of load regulation for one, since a blocking send would no longer imply that incoming messages are no longer recevied. Dealing with this could result in the same deadlock that the sending process intends to avoid, but the user should be in control over how/when incoming traffic is regulated.
2017-06-11Remove upgrade from diameter_sctp; tweak diameter_tcp to matchAnders Svensson
Added in commit 2afd1fe5. Only rename variables in diameter_tcp, no functional change.
2017-06-11Fix incomprehensible dialyzer warningAnders Svensson
This: diameter_tcp.erl:241: Record construction #transport{parent::'false',ssl::boolean() | maybe_improper_list(),frag::<<>>,tref::'false',flush::'false',pending::0,reset::{1 | 4,0 | 2},throttled::boolean(),q::{0,queue:queue(_)},monitor::'undefined' | pid()} violates the declared type of field parent::pid() The problem isn't #transport.pid at all, it's #monitor.pid, and the only relation is that the pid that's assigned to the latter is also (later) assigned to the former. There is no record construction that assigns false to #transport.parent. Introduced in commit 33a535e4.
2017-06-11Simplify acks to transport processesAnders Svensson
What's interesting when implementing some form of load regulation is when an incoming request has been answered or discarded. Acknowledge exactly this, not the identity of handler processes as previously. A transport process can request acks of nonforthcoming answers by sending {diameter, ack} to the parent peer_fsm, a handler processes identifies itself with a {handler, pid()} message, and the peer_fsm monitors on this to be able to send a notification to the transport if the handler dies before sending an answer.
2017-06-11Strip throttling callbacks from diameter_tcpAnders Svensson
Commits starting at 472a080c added a throttle_cb option to diameter_tcp to let a callback apply backpressure when it decides that additional requests should not be read. It didn't provide a hook for knowing that an answer was sent however, which is needed when sends no longer take place in the receiver process, and is more complicated than it should be. Strip it all away, in preparation for a simpler incarnation.
2017-06-11Deal with (another) SCTP association id quirk on SolarisAnders Svensson
Shutdown events have been seen to get a different association id. For example, first incoming message with association id = 0: + {trace_ts,<6421.268.0>,call, {diameter_sctp,handle_info, [{sctp,#Port<6421.2588>, {10,67,16,179}, 44159, {[{sctp_sndrcvinfo,0,0,[],0,0,0,269950872,269950872,0}], <<1,0,0,156,128,0,1,1,0,0,0,0,6,193,40,137,6,193,40,137,0,0, 1,8,64,0,0,30,67,45,49,51,52,50,49,55,52,52,49,46,101,114, 108,97,110,103,46,111,114,103,0,0,0,0,1,40,64,0,0,18,101, 114,108,97,110,103,46,111,114,103,0,0,0,0,1,1,64,0,0,14,0, 1,127,0,0,1,0,0,0,0,1,10,64,0,0,12,0,0,48,57,0,0,1,13,0,0, 0,20,79,84,80,47,100,105,97,109,101,116,101,114,0,0,1,22, 64,0,0,12,0,0,0,1,0,0,1,2,64,0,0,12,0,0,0,0,0,0,1,3,64,0,0, 12,0,0,0,3>>}}, {transport,<6421.252.0>,accept,#Port<6421.2588>,true,undefined, {32,32}, 0,undefined}]}, {1493,21505,577938}} Later, a shutdown event with association id 1536: + {trace_ts,<6421.268.0>,call, {diameter_sctp,handle_info, [{sctp,#Port<6421.2588>, {10,67,16,179}, 44159, {[],{sctp_shutdown_event,1536}}}, {transport,<6421.252.0>,accept,#Port<6421.2588>,0,undefined, {32,32}, 2,<6421.304.0>}]}, {1493,21505,746929}} Both this and the grandparent commit are on this: $ uname -a SunOS beren 5.10 Generic_118833-33 sun4v sparc SUNW,Netra-T2000
2017-06-11Use binary:copy/2 when generating largish data in test suitesAnders Svensson
Faster than lists:duplicate/2.
2017-06-11Deal with SCTP association id quirk on SolarisAnders Svensson
In particular, that the association id received in messages on a one-to-one socket after peeloff may be different from the id received on the listen socket at comm_up. This seems odd, since it's then not possible to send until the id is discovered by reception of an SCTP message containing it, but it's unclear if this is a bug or a feature, or if it's specific to certain platforms. Treat it as a feature in this commit, and get the association id as mentioned, an incoming CER being expected before anything is sent. Commit da3e5d67 has more history.
2017-06-11Make skipped SCTP testcases more visible in traffic suiteAnders Svensson
By explicitly skipping instead of omitting testcases from groups.
2017-06-11Make traffic suite fail less brutallyAnders Svensson
Autoskip traffic testcases if transport isn't established instead of having traffic cases run and fail.
2017-06-11Remove superfluous traffic testcaseAnders Svensson
Testcase is already run elsewhere on the suite.
2017-06-11Rework gen_sctp suite to demonstrate remaining problemsAnders Svensson
In particular, that transmission can be very slow. The problem appears to be linked to sndbuf/recbuf, but even with buffers that are large enough to hold all messages being sent, turnaround times can still vary by hundreds of milliseconds in a reasonable test environment. Use multiple streams and a sender process to more closely mirror the usage in diameter_sctp, but neither is the source of the problems.
2017-06-11Fix diameter_transport_SUITE raceAnders Svensson
The server sent and died, but there's no guarantee that it won't take the connection down before the client has receive its bytes. Make the server wait for the client to take down the connection.
2017-06-11Work around SCTP quirks on sparc-sun-solaris2.10Anders Svensson
This addresses the testcase failures mentioned in the parent commit, which has been on account of the behaviour below, in which connect fails on the loopback address. Work around it by finding/using another address if possible. $ erl Erlang/OTP 20 [DEVELOPMENT] [erts-9.0] [smp:2:2] [ds:2:2:10] [async-threads:10] [hipe] [kernel-poll:false] [sharing-preserving] Eshell V9.0 (abort with ^G) 1> {ok, LP} = gen_sctp:open(). {ok,#Port<0.439>} 2> gen_sctp:listen(LP, true). ok 3> inet:socknames(LP). {ok,[{{10,67,16,178},36506},{{127,0,0,1},36506}]} 4> {ok, S} = gen_sctp:open([{ip, {127,0,0,1}}]). {ok,#Port<0.443>} 5> gen_sctp:connect_init(S, {127,0,0,1}, 36506, []). {error,eaddrnotavail} 6> gen_sctp:connect_init(S, {10,67,16,178}, 36506, []). {error,eaddrnotavail} 7> gen_sctp:close(S). ok 8> f(S). ok 9> {ok, S} = gen_sctp:open(). {ok,#Port<0.444>} 10> gen_sctp:connect_init(S, {127,0,0,1}, 36506, []). ok Even the following has been seen on at least one host, so that success of gen_sctp:open/0 is no guarantee. $ ifconfig -a4 lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1 inet 127.0.0.1 netmask ff000000 bge0: flags=1004843<UP,BROADCAST,RUNNING,MULTICAST,DHCP,IPv4> mtu 1500 index 2 inet 10.67.16.180 netmask ffffff00 broadcast 10.67.16.255 $ erl Erlang/OTP 20 [DEVELOPMENT] [erts-9.0] [source] [smp:2:2] [ds:2:2:10] [async-threads:10] [hipe] [kernel-poll:false] Eshell V9.0 (abort with ^G) 1> {ok, S} = gen_sctp:open(), 1> gen_sctp:connect(S, {127,0,0,1}, 3868, []). {error,eafnosupport} 2> gen_sctp:connect(S, {10,67,16,180}, 3868, []). {error,eafnosupport}
2017-06-11Revert "diameter: Do not test SCTP on sparc-sun-solaris2.10"Anders Svensson
The comment in commit 736ce20a isn't quite true. There's no different behaviour that diameter doesn't support, but there is a quirk with the loopback address that has caused many testcases to fail. This will be addressed in a subsequent commit. Reverts commit 736ce20a.
2017-06-11Add missing dialyzer typesAnders Svensson
Which dialyzer itself has never complained about.
2017-06-11Don't send from receiving transport processesAnders Svensson
Both diameter_tcp and diameter_sctp are susceptible to deadlock since a peer that blocks send also prevents additional messages from being received. Send from a process that's paired with the transport process to avoid this. Use the existing monitor process in the TCP case, add one in the SCTP case. This has been the reason for many sporadic testcase failures, mostly in diameter_traffic_SUITE.
2017-06-11Fix gen_tcp close of ssl socketAnders Svensson
Should be ssl:close/1.
2017-06-11Remove clauses supporting old codeAnders Svensson

2017-06-11Correct comment typoAnders Svensson
2017-06-11Fix handling of message length errorsAnders Svensson
Message length errors in incoming messages were misinterpreted with transport_opt() {length_errors, exit} due to the throw introduced in commit 2ffb288: the corresponding catch in incoming/2 caught errors thrown by close/1, leading to failure when the error reason was interpreted as a diameter_packet record. Do away with the throw, that also caused woe in the parent commit.
2017-06-11Fix broken discard acknowledgementAnders Svensson
A transport process can request acknowledgement of the fate of an incoming message to a specified pid, causing it to receive one of {diameter, {request|answer, pid()} | discard} depending on whether or not diameter passes the message off to a handler process. This was broken in commit a4da06a5 (since recv/3 threw a message that should be received), but is of little consequence since the interface isn't yet documented and is only used from diameter_tcp with configuration that will soon change.
