2015-06-19Simplify peeloff signalingAnders Svensson
In particular, don't give the accepting transport process the listening socket. It was used to match the initial sctp message received in a peeloff message, but replace the socket in the forwarded message instead.
2015-06-19Simplify socket close at terminateAnders Svensson
The existing code was a remnant of the pre-peeloff implementation. There's no need to close anything but the whole socket.
2015-06-19Don't monitor listener after peeloffAnders Svensson
Listener death should have no effect on a peeled off association.
2015-06-19Don't receive initial messages out of orderAnders Svensson
Forwarding an sctp message from the listener process at the same time that the controlling process is changed means there's no guarantee that the message order will be preserved. Selectively receive the peeloff message before entering the gen_server loop to ensure the order is preserved.
2015-06-19Remove assumption that SCTP association ids will be uniqueAnders Svensson
This is not the case under Solaris for one: successive associations can receive the same association id as a result of peeloff, the id only being unique for the controlling port, not for the listening port as is the case under Linux for example. This made for many failures in the diameter test suites, the traffic suite in particular. Peeloff in diameter_sctp was introduced in 9a671bf0, before which the assumption was fine since it was the listening process that owned all associations. (Which obviously had other drawbacks.) Other remnants of the pre-peeloff implementation have also been removed: that the listener process might receive a message on a socket after peeloff for one. Peeloff in gen_sctp became available in commit 067cfe79, after the original implementation of diameter_sctp. This is trace on the unpatched code showing id reuse under Solaris: + {trace_ts,<0.103.0>,call, {diameter_sctp,handle_info, [{sctp,#Port<0.1625>, {127,0,0,1}, 35904, {[],{sctp_assoc_change,comm_up,0,32,32,1}}}, {listener,#Ref<0.0.1.948>,#Port<0.1625>,4, 57384, {-4,61481}, #Ref<0.0.8.12>, []}]}, {1432,458752,612168}} + {trace_ts,<0.103.0>,call, {diameter_sctp,handle_info, [{sctp,#Port<0.1625>, {127,0,0,1}, 35905, {[],{sctp_assoc_change,comm_up,0,32,32,1}}}, {listener,#Ref<0.0.1.948>,#Port<0.1625>,4, 57384, {-3,61481}, #Ref<0.0.8.12>, []}]}, {1432,458752,613042}} The result was this, when the second association was incorrectly forwarded to the first association's controlling process: ** {function_clause, [{diameter_sctp,transition, [{peeloff,#Port<0.1635>, {sctp,#Port<0.1625>, {127,0,0,1}, 35892, {[],{sctp_assoc_change,comm_up,0,32,32,1}}}, []}, {transport,<0.107.0>,accept,#Port<0.1634>,1,undefined,{32,32},0}], [{file,"transport/diameter_sctp.erl"},{line,561}]}, {diameter_sctp,t,2,[{file,"transport/diameter_sctp.erl"},{line,549}]}, {diameter_sctp,handle_info,2, [{file,"transport/diameter_sctp.erl"},{line,397}]}, {gen_server,try_dispatch,4,[{file,"gen_server.erl"},{line,614}]}, {gen_server,handle_msg,5,[{file,"gen_server.erl"},{line,680}]}, {proc_lib,init_p_do_apply,3,[{file,"proc_lib.erl"},{line,238}]}]}

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.

To see why it's failing on at least one test machine.

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.

2015-05-13ssh: option for handling the SSH_MSG_DEBUG message's printoutsHans Nilsson
A fun could be given in the options that will be called whenever the SSH_MSG_DEBUG message arrives. This enables the user to format the printout or just discard it. The default is changed to not print the message. In RFC4253 printing is a SHOULD, but our new default is to protect logs from dos attacs.
