2011-05-04Fix bug in halfword emulator causing ets:select_delete on ordered_set to crashSverker Eriksson

* rickard/process-status/OTP-9197: Fix thread unsafe access Fix lost wakeup when process garbage collected by other Only set status P_WAITING when needed Add testcase for process_info() badarg bug
2011-04-11Fix thread unsafe accessRickard Green
Fix thread unsafe access to process status field introduced in OTP-9125.
2011-04-11Fix lost wakeup when process garbage collected by otherRickard Green
2011-04-11Only set status P_WAITING when neededRickard Green
The status of a process was unnecessarily set to waiting before the process was enqueued in a run queue. This bug was harmless up until OTP-R14B01. In OTP-R14B02 erlang:hibernate/3 was fixed (OTP-9125). After the introduction of OTP-9125, the previously harmless process status bug sometimes caused erroneous badarg exceptions from process_info().

2011-03-10Merge branch 'sverker/valgrind-new-suppressions' into devSverker Eriksson
* sverker/valgrind-new-suppressions: Make halfword emulator with valgrind target allocate low memory Add erts_alloc_permanent_cache_aligned to supress valgrind
2011-03-09Make halfword emulator with valgrind target allocate low memorySverker Eriksson
Limit ERTS_MSEG_FAKE_SEGMENTS (that is otherwise set for valgrind target) to not apply to low memory needed by halfword emulator. This will reduce the fault detection capability of valgrind for low memory. Also correct a bug in the initial mmap and make sure the returned memory region does not reach into high memory.
2011-03-09Fix 18 exabyte memory allocation failureBjörn Gustavsson
The new_binary() function takes a size argument that is an int. In the 64-bit emulator (sizeof(int) == 4, sizeof(Uint) == 8), any sizes >= 0x8000000 become 0xffffffff80000000 and above and triggers a memory allocation failure. Change the type of the size argument to Uint, and change any callers that cast the argument to an int. Correction-by: Jon Meredith

2011-03-04erts: Initialize register that may be referenced by garbage collectionBjörn Gustavsson
The call_fun() function in the BEAM emulator is supposed to to put the fun term in the x register following the actual arguments and environment for the fun. But if the fun is not loaded and a call to the error_handler:undefined_lambda/3 function is set up, the x(3) register will not be initialized. The lack of initialization is very unlikely to cause a problem in practice, because all of the following things must happen: 1) An unloaded fun must be called (i.e. the fun must have been received from another node or from a file or dets table). 2) The process must be scheduled out before the call to the error_handler:undefined_lambda/3 function can take place. 3) The process must be garbage collected before the process is scheduled in. 4) The x(3) register must contain a stale cons or box pointer that happens to point into the the heap of the currently executing process. (Because of the literal pool, the GC will never copy anything that is outside of the heap.) I was not able to write a test case that would force an emulator crash.

2011-02-23beam_emu: Remove unnecessary decrement of I in "case_end r"Björn Gustavsson
It is not necessary to decrement I, because an exception is about to be generated. Furthermore, I pointing *before* the instruction that caused the exception may cause problems in the future.
2011-02-21Allow unexpected driver input event in driver_SUITE:smp_selectSverker Eriksson
epoll on Linux has been seen to sometimes trigger unexpected events. Most of the time these events are filtered by erl_check_io, but may slip up to the driver in cases when fd's are reused. Also made clear in driver docs that spurious events may happen.
2011-02-21Add patch from Per HedelandPatrik Nyblom
Per H @ Tail-f: The original code here had problems that possibly only occur if you abuse it for non-INET sockets, but anyway: a) If the getsockopt for SO_PRIORITY or IP_TOS failed, the actual requested setsockopt was never even attempted. b) If {get,set}sockopt for one of IP_TOS and SO_PRIORITY failed, but ditto for the other worked and that was actually the requested option, failure was still reported to erlang.
