2017-08-30erts: Fix crash in binary_to_atom/term for invalid utf8Sverker Eriksson
such as a sub-binary, of a correct utf8 string, that ends in the middle of a character.
2017-07-12erts: Fix bug in bxor of a big negative numberSverker Eriksson
Wrong result for (X bsl WS) bxor Y. where X is any negative integer Y is any integer that does not require more words than X WS is erlang:system_info(wordsize) or larger Fix: The subtraction of 1 (for 2-complement conversion) must be carried along all the way to the last words.
2017-01-23erts: Fix binary_to_term for compressed and zlib >= v1.2.9Sverker Eriksson
Problem: z_stream was incorrectly copied with memcpy which just happened to work with zlib < v1.2.9. Solution: Avoid copying z_stream.
2016-09-05Fix erts_thr_progress_unmanaged_delay()Rickard Green
Thread progress leader update did not cache current unmanaged index when waiting for unmanaged threads. This caused erts_thr_progress_unmanaged_delay() to stop working until a new leader took over.

2015-12-04Remove ERTS_PRINT_INVALID from erts_print()Rickard Green
ERTS_PRINT_INVALID prevented file descriptor 0 to be used which could cause an empty crash dump.
2015-09-07Merge branch 'sverk/trace-process_dump-matchstate-17/OTP-12968' into maint-17Erlang/OTP
* sverk/trace-process_dump-matchstate-17/OTP-12968: erts: Add testcase for tracing whith 'process_dump' erts: Fix bug when tracing with 'process_dump'
2015-09-01erts: Fix bug when tracing with 'process_dump'Sverker Eriksson
If the process stack contained a match state the print function would crash the vm as it was not recognized by tag_val_def(). Add new MATCHSTATE_DEF returned by tag_val_def(). All other callers either ignore it or has a default clause to handle invalid terms.

2015-05-25erts: Fix garbage collect literals in code purgeBjörn-Egil Dahlberg
During code purging and check_process_code, the checking of the binary reference embedded in the match binary state was omitted for the tracing tests. This would cause the binary match state to reference deallocated memory.

list_to_integer(lists:duplicate(10000000,$0)). crashed due to overflow when calculating nr heap words.
2015-03-25erts: Enable command line argument for initial pd sizeBjörn-Egil Dahlberg
Use '+hpds size' to set initial process dictionary size for spawned processes.
2015-03-24erts: Fix comparison of exact termsBjörn-Egil Dahlberg
Comparison of exact terms could cause faulty term tests. This was caused by a faulty (too small) internal type. Symptom: -1 = erts_internal:cmp_term(2147483648,0). %% wrong Correct: 1 = erts_internal:cmp_term(2147483648,0). Reported-by: Jesper Louis Andersen

2015-02-14don't leave a heap hole in erts_bs_get_integer_2Mikael Pettersson
Reset p->htop in the oversize bignum error case to avoid leaving a hole in the heap, which would crash the debug emulator.
2015-02-04don't create oversize bignums in binary matchingMikael Pettersson
Bignums are artifically restricted in size. Arithmetic and logical operations check the sizes of resulting bignums, and turn oversize results into system_limit exceptions. However, this check is not performed when bignums are constructed by binary matching. The consequence is that such matchings can construct oversize bignums that satisfy is_integer/1 yet don't work. Performing arithmetic such as Term - 0 fails with a system_limit exception. Worse, performing a logical operation such as Term band Term results in []. The latter occurs because the size checking (e.g. in erts_band()) is a simple ASSERT(is_not_nil(...)) on the result of the bignum operation, which internally is [] (NIL) in the case of oversize results. However, ASSERT is a no-op in release builds, so the error goes unnoticed and [] is returned as the result of the band/2. This patch addresses this by preventing oversize bignums from entering the VM via binary matching: - the internal bytes_to_big() procedure is augmented to return NIL for oversize results, just like big_norm() - callers of bytes_to_big() are augmented to check for NIL returns and signal errors in those cases - erts_bs_get_integer_2() can only fail with badmatch, so that is the Erlang-level result of oversize bignums from binary matches - big_SUITE.erl is extended with a test case that fails without this fix (no error signalled) and passes with it (badmatch occurs) Credit goes to Nico Kruber for the initial bug report.

2015-01-13erts: Extend driver interface with emergency_closeBjörn-Egil Dahlberg
The intention of this callback is to close all sockets associated to a port. It is closed only on crashdumps. This will currently only be used for the epmd port.

The 64-bit atomic ops API is implemented by * native word size atomic ops on 64-bit architectures, and * native double word size atomic ops on 32-bit architectures when available. When native double word size atomic is not available, the fallback using modification counters is used.
