2018-02-26erts: Delay cleanup of removed tracer on dirty schedsLukas Larsson
It is not simple to do the correct de-allocation on a dirty schedulers, so we just delay it until this process runs on a normal scheduler.

2018-02-20erts: Cleanup dump_process_info()Sverker Eriksson
by testing F_SENSITIVE only once.
2018-02-20erts: Include failing garbing process in crash dumpSverker Eriksson
Exclude garbing processes, EXCEPT if run by crash dumping thread in which case we assume the heap is healthy without any move markers yet/left. Switched order between (allocating) setup_rootset() and (move marking) collect_live_heap_frags().

2018-02-15badarg on iolist_to_binary(Bitstring)John Högberg
When supplied without an enclosing list, bitstrings were returned as-is instead of badarging.
2018-02-15Handle unaligned binaries in enif_inspect_iovecJohn Högberg
2018-02-15Handle unaligned binaries in erlang:iolist_to_iovec/1John Högberg
A binary is a binary as long as its size in bits is evenly divisible by 8, regardless of whether it has a bit offset or not.
2018-02-15badarg on iolist_to_iovec(Bitstring)John Högberg
When supplied without an enclosing list, bitstrings were silently truncated to [] instead of badarging.
2018-02-15Test badarg when an improper list tail contains a bitstringJohn Högberg
This has always worked but we lacked test coverage for it.
2018-02-15kernel: Reject load of module names with slashSverker Eriksson
or backslash on Windows. Purpose: Prevent tricks to get hostile code running.
2018-02-13Use smaller inputs in iovec testsJohn Högberg
Huge inputs weren't particularly useful and took forever to run, so this commit winds it down to a more sane level that still causes lots of yielding.

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.

2018-01-24kernel: Ignore cores in erl_distribution_SUITELukas Larsson
Some bash versions segfault when a unicode argument is given so we ignore cores created by nodes spawned by this testcase.
2018-01-17Fix slow hipe executionSverker Eriksson
particularly slow erlc when compiler is hipe compiled. hipe_unified_loader:load did not patch external call sites and instead caused a double hipe mode switch per call. hipe_unified_loader:load is only used for early modules first loaded as beam and by code:atomic_load and friends.

2018-01-15erts: Refactor and cleanup sys_double_to_chars_fastSverker Eriksson
Replace long long with Uint64
2018-01-15erts: Fix float_to_list(F, [{decimals,D}]).Sverker Eriksson
Example symptom: 1> float_to_list(0.145, [{decimals,1}]). "0.2" There were two problems in sys_double_to_chars_fast 1. Most serious was adding 0.55555555 / (10^D) instead of 0.5 / (10^D) which imposed a 5.5% risk of a faulty rounding up. 2. Using fixpoint for frac_part which lost significant bits if F < 0.5
2018-01-15erts: Fix buffer overflow bug in erts_printf %fSverker Eriksson
Sign character was not accounted for. Ex: float_to_list(-3.1265538967899625e+69, [{decimals,16}]).
