2018-02-12Automatically start lcnt server on first useJohn Högberg
lcnt:collect is documented as implicitly starting the lcnt server but didn't do so prior to this commit. I've decided to extend this behavior to all operations as the overhead is negligible and it's a bit more convenient to use.

dumbbell/dumbbell/ssl/fix-active-once-dropped-when-handling-alert/ERL-562 ssl: Fix alert handling so that unexpected messages are logged and alerted correctly
2018-02-09Check that the stack is initialized when an exception may occurBjörn Gustavsson
Strengthen beam_validator to check that the stack is initialized when an instruction with an {f,0} operand is executed. For example, the following code sequence: {allocate,0,1}. {bif,element,{f,0},[{integer,1},{x,0}],{x,0}}. should not be accepted because the stack may be scanned if element/2 fails. That could cause a crash or other undefined behavior if garbage on the stack looks like a catch tag.
2018-02-09ssl: Add the unexpected message to #alert{}Jean-Sébastien Pédron
... in handle_common_event(), instead of passing it to handle_own_alert() after wrapping it in a tuple with `StateName` (i.e. `{StateName, Msg}`). The `StateName` is passed to handle_normal_shutdown() and to alert_user(). The latter has a clause matching it against `connection`. Unfortunately, when the argument was in fact `{StateName, Msg}`, another clause was executed which dropped the `active` flag value and forced it to `false`, even if the state was actually `connection`. It meant that later in send_or_reply(), the alert was not propagated to the user, even though it should (`active` set to `true` or `once`). Now that handle_common_event() always passes the actual `StateName`, the problem is fixed. ERL-562

2018-02-07ssl: Make sure anonymous suites are handled separatelyIngela Anderton Andin
Preferably customized cipher suites will be based on the default value. But all may be used as base and hence it will be good to handle anonymous suites separately as they are intended for testing purposes.

2018-02-05ssl: Uses aead as mac value in AEAD cipher suitesIngela Anderton Andin
Authenticated encryption (AE) and authenticated encryption with associated data (AEAD, variant of AE) is a form of encryption which simultaneously provides confidentiality, integrity, and authenticity assurances on the data. This is more logical value then null that was used, this happened to work as the AEAD property was derived form other data, but it is confusing!

2018-01-19ErLLVM: Preserve precise BEAM tailcall semanticsMagnus Lång
The BEAM compiler chooses not to perform tailcall optimisations for some calls in tail position, for example to some built-in functions. However, when the ErLLVM HiPE backend is used, LLVM may choose to perform tailcall optimisation on these calls, breaking the expected semantics. To preserve the precise semantics exhibited by BEAM, the 'notail' marker, present in LLVM since version 3.8, is added to call instructions that BEAM has not turned into tail calls, which inhibits LLVM from performing tail-call optimisation in turn.
