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().

The emulator could get into a state where it didn't check for I/O.
|
|
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.

* sverker/clarify_nif_resource_doc:
clarify NIF resource object deallocation documentation
|
|
In the erl_nif documentation, clarify how and when NIF resource
objects can be deallocated. Specifically, add focus for the case of
calling enif_release_resource immediately after obtaining a resource
term from enif_make_resource, since this is likely to be a common
approach NIFs use to manage resources.
Also fix a couple misspellings in the erl_nif documentation.

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.

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.
