2019-01-30erts: Fix compiler warning for IS_SSMALLSverker Eriksson
"shift count negative or too big, undefined behavior"
2019-01-30Fix bug in binary:encode_unsigned causing a read of uninitialized memoryKjell Winblad
The bug could be seen by running the test that is added by this commit in a valgrind enabled emulator. Co-authored-by: John Högberg <[email protected]>
2019-01-28erts: Add magic port control numbersSverker Eriksson
to increase the probablity of a nice badarg from erlang:port_control.
2019-01-28Add -ztma option for enabling tuple callsRichard Carlsson
2019-01-28Reinstate tuple calls support in the beam emulatorRichard Carlsson
This reverts commit f2b332186a for beam_emu.c only, to enable an upgrade path for existing beam code compiled under OTP 20 with parameterized modules.

2019-01-18erts: Use reduction based polling for starved poll-setLukas Larsson
When the schedulers never go to sleep (and thus never polls) it may be that the fds in schedulers poll-sets are never polled. Before this commit, this was solved by starting a timer when an overload was detected. This had issues as overloads were not always detected in time. So this commit reverts to the pre OTP-21 behaviour so keep a global counter makes that the poll is called when it should.

This flag allows logger and other components to set the process which log messages from ERTS are to be sent.
2019-01-10Fix passing large integers as base to integer_to_X/2John Högberg
I noticed this seconds after merging... :(

This makes them roughly as fast as integer_to_list/1 and integer_to_binary/1.

2019-01-07erts: Fix process_SUITE:max_heap testsLukas Larsson
Make sure to flush all queued emulator logger messages before starting the test. The trap_exit_badarg could sometimes leave messages and since the handler and messages now are handled in different processes this becomes a problem.

Similar bug as for bxor fixed by abc4fd372d476821448dfb9 Ex: 1> io:format("~.16B\n", [-16#1110000000000000000 band (-1)]). -1120000000000000000 Wrong result for (-X bsl WS) band -Y. where X is any positive integer WS is erlang:system_info(wordsize)*8*N where N is 1 or larger Y is any positive integer smaller than (1 bsl WS) Fix: The subtraction of 1 (for 2-complement conversion) must be carried along all the way to the last words.

2018-12-13erts: Fix possible heap corruption getting atomicsTomas Abrahamsson
Due to comparison as a signed integer, when getting an unsigned atomic in the range 2^63-1..2^64-1 (when the most significant bit was set), the heap could get corrupted when the integer was retrieved: hsz would get set to zero, but the code proceeded to build a bignum. Steps to reproduce (at least on x86_64): $ erl 1> A = atomics:new(1,[{signed,false}]). 2> atomics:put(A,1,18446744073709551615). 3> atomics:get(A,1). At the last step, the shell would print some garbage and hang.

2018-12-13erts: Fix seq_trace:reset_trace dirty gc bugLukas Larsson
When seq_trace:reset_trace could be called while a process was doing a dirty GC. This triggered a race where all signals was moved to the internal signal queue during the GC which in turn caused the a heap overrun problem. This fix makes it so that the main and msgq lock are taken before the clear. This will make sure that we are allowed to do the clear.
