2018-02-14beam_block: Combine blocks when running beam_block the second timeBjörn Gustavsson
1a029efd1ad47f started to run the beam_block pass a second time, but it did not attempt to combine adjacent blocks. Combining adjacent blocks leads to many more opportunities for optimizations. After doing some diffing in generated code, it turns out that there is no benefit for beam_split to split out line instructions from blocks. It seems that the only reason it was done was to slightly simplify the implementation of the no_line_info option in beam_clean.
2018-02-14Disable CSE for floating point operationsBjörn Gustavsson
As a preparation for combining blocks before running beam_block for the second time, disable CSE for floating point operations because it will generate invalid code.

2018-02-13Fix size of fmt_double()'s format_str[] bufferMikael Pettersson
fmt_double() may write up to 8 characters into its format_str[] buffer, which however only has room for 7 characters. This case could be triggered by a call to erts_printf_format() with any floating-point format that also includes #, and + or a space, which may be uncommon, but a nif or driver could issue it.

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.
2018-02-12Fix unsafe use of 'allocate' where 'allocate_zero' should be usedBjörn Gustavsson
The more aggressive optimizations of 'allocate_zero' introduced in cb6fc15c35c7e could produce unsafe code such as the following: {allocate,0,1}. {bif,element,{f,0},[{integer,1},{x,0}],{x,0}}. The code is not safe because if element/2 fails, the runtime system may scan the stack and find garbage that looks like a catch tag, and would most probably crash. Fix the problem by making beam_utils:is_killed/3 be more conservative when asked whether a Y register will be killed. Also fix an unsafe move upwards of an allocation instruction in beam_block.

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.
