When the Server header has empty info (or 'none' in config), it is not generated. This is for limiting Banner Grabbing attempts.

2015-04-07ssh: fix loop bug for zero maximum_packet_size.Hans Nilsson
A channel could be opened with the 'max packet size' set to 0. The behaviour is not defined in the ssh rfc:s, and openssh does not handle that case in some special way besides looping. The introduced solution just "keep quiet" but removes the eternal loop that caused Erlang to core dump.
2015-04-07ssh: Add ssh_info:print/1 to write onto a file descriptorHans Nilsson
2015-04-07ssh: Add {active, false} to ssh listen socketIngela Anderton Andin
The ssh acceptor process listens for connections and spawns a process to handle each new connection that it accepts. The ownership of the accepted socket will be transfered to the new process that will handle the incomming messages. Before the ownership is transfered the socket should be in {active, false} or the acceptor process may receive data aimed for the connection. As the accept socket inherits the listen options we set {active, false} there.
2015-04-07ssh: Change send_buf implementation from list to queueIngela Anderton Andin
A queue is the behaviour that we want, so this makes the code easier to understand and more effective.
2015-04-07ssh: Remove error reportIngela Anderton Andin
The error report was assumed to only happen if our code was wrongly implemented "internal error". However it would also occur when bad input was recived from the peer, and could hence cause extensive logging on DoS attacks.

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.

* egil/maint/process_dictionary-initial-size/OTP-12535: erts: Document option 'hpds' erts: Enable command line argument for initial pd size
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.

2015-03-24erts: Fix comparison of exact termsBjörn-Egil Dahlberg
Comparison of exact terms could cause faulty term tests. This was caused by a faulty (too small) internal type. Symptom: -1 = erts_internal:cmp_term(2147483648,0). %% wrong Correct: 1 = erts_internal:cmp_term(2147483648,0). Reported-by: Jesper Louis Andersen

* anders/diameter/DiameterURI/OTP-12589: Adapt to changed DiameterURI defaults in RFC 6733 Reject transport=udp;protocol=diameter at DiameterURI encode
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.
