2011-10-11Get rid of redundant 'try_me_else' and 'fail' instructionsBjörn Gustavsson
If the left part of a transformation will always match, omit the the 'try_me_else' and 'fail' instructions. As part of this optimization, make it an error to have a transformation that can never be reached because of a previous transformation that will always match. (Remove one transformation from ops.tab that was found to be unreachable.)
2011-10-11Add some more information in instruction commentsBjörn Gustavsson
2011-10-11In transformations, don't store variables that are never usedBjörn Gustavsson
This optimization will save some space (in the loader tables) and some loading time.
2011-10-11Remove redundant 'next_arg' before 'next_instr'Björn Gustavsson
Fix the incorrect code that attempted to remove a single 'next_arg' instructions before 'next_instr'.
2011-10-11Generalize and rename is_set_var_instr() to is_instr()Björn Gustavsson
It is more useful to have a helper function that can test for any instruction.
2011-10-11Remove too_old_compiler handling for very old instruction variantsBjörn Gustavsson
is_list/2 and other test instructions with a zero label was last generated by the v1 BEAM compiler which was last supported in R6B. Since BEAM modules produced by that compiler will be rejected with a nice error message for other reasons (e.g. by the test for the module_info/0,1 functions), retaining those transformations serves no useful purpose.
2011-10-11Remove the special instructions for the hybrid heap emulatorBjörn Gustavsson
The hybrid-heap emulator is broken since R12, so there is no need to keep those instructions.
2011-10-11Remove optimization of 'move R R'Björn Gustavsson
Ancient versions of BEAM compiler could generate move instruction with the same source and destination registers, so the loader would optimize away such instructions.

Previously error:badarg was raise if there was no underlying support for SCTP. Handle both new and old failure until OTP-9239 is merged.
2011-10-07Make testsuites more robust in case of init failureAnders Svensson
In particular, move code out of init_per_suite since failure causes end_per_suite to be skipped. Cleanup is simpler if both init and cleanup happen as testcases.

2011-10-07Add '-callback' attributes in stdlib's behavioursStavros Aronis
Replace the behaviour_info(callbacks) export in stdlib's behaviours with -callback' attributes for all the callbacks.

2011-10-07Update the documentation with information on the callback attributeStavros Aronis
2011-10-07Automatically generate 'behaviour_info' function from '-callback' attributesStavros Aronis
'behaviour_info(callbacks)' is a special function that is defined in a module which describes a behaviour and returns a list of its callbacks. This function is now automatically generated using the '-callback' specs. An error is returned by lint if user defines both '-callback' attributes and the behaviour_info/1 function. If no type info is needed for a callback use a generic spec for it.
2011-10-07Add '-callback' attribute to language syntaxStavros Aronis
Behaviours may define specs for their callbacks using the familiar spec syntax, replacing the '-spec' keyword with '-callback'. Simple lint checks are performed to ensure that no callbacks are defined twice and all types referred are declared. These attributes can be then used by tools to provide documentation to the behaviour or find discrepancies in the callback definitions in the callback module.

Also update app testsuite to allow for "undefined" calls from diameter_tcp to ssl.
2011-10-06Add tls support at connection establishmentAnders Svensson
This is the method added in draft-ietf-dime-rfc3588bis, whereby a TLS handshake immediately follows connection establishment and CER/CEA is sent over the secured connection.

2011-10-06Close transport if tls is requested over sctpAnders Svensson
RFC 3588 requires that a Diameter server support TLS but in practise this seems to mean TLS over SCTP since there are limitations with running over SCTP: see RFC 6083 (DTLS over SCTP), which is a response to RFC 3436 (TLS over SCTP). The current RFC 3588 draft acknowledges this by equating the Inband-Security-Id value TLS with TLS/TCP and DTLS/SCTP but underlying support for DTLS is still thin on the ground.
2011-10-06Handle tls notification for tcpAnders Svensson
If TLS has been configured on Inband-Security-Id then the transport process receives a message from the peer_fsm process indicating whether or not to upgrade to TLS. The current draft of RFC 3588 deprecates (but retains for backwards compatibility) the use of Inband-Security-Id for negotiating TLS, adding the possibility of TLS having be negotiated before capabilities exchange. This commit handles the deprecated case.
2011-10-06Lift recursion in tcp message reception up the call chainAnders Svensson
When an initial message is received and TLS is a possibility, must wait for a message from the peer process before either commencing a handshake or receiving more messages.
2011-10-06Add tls support to capabilities exchangeAnders Svensson
To upgrade a connection to TLS or not, that is the question. It is possible for us to send a CER offering both NO_INBAND_SECURITY and TLS and for the peer to answer likewise: RFC 3588 doesn't make clear that a CEA should be unambiguous about the choice of security. Thus, if TLS is offered then assume the server is prepared to for a handshake. Similarly, when receiving a CER, choose TLS if it's offered and be unambiguous about our choice in CEA. There is no ssl:maybe_accept that would let us receive a handshake if it comes or another message if it doesn't. The choice of TLS should probably be made into a callback so that an application can decide based on the peer's Origin-Realm for example. Such a callback could also be used to reject a CER/CEA. Handle Inband-Security-Id values other than NO_INBAND_SECURITY and TLS by assuming that they require no intervention by the transport module, treating them like NO_INBAND_SECURITY. Whether or not this is reasonable (or useful) is unclear. There may be a need for more sychronization than we have on offer. (Having to do something before taking the connection up for example.) Note that diameter_peer_fsm must be upgraded before diameter_capx because of the new return value from diameter_capx:recv_CEA/2.
