2014-03-28prevent NIF purge during dirty NIF executionSteve Vinoski
Reference-count the NIF before and after invoking a NIF on dirty schedulers to prevent having the NIF purged during the call.
2014-03-28fix dirty NIF invalid memory readSteve Vinoski
Dirty NIF support used an Export structure to facilitate calls to dirty NIFs and finalizers, but Export isn't large enough to hold all necessary data. This was causing an invalid memory read in beam_emu.c past the end of the Export object. Add a local extended Export struct to erl_nif.c that can hold all the necessary data.

2014-03-27erts: Fix bug of scheduling a suspended processSverker Eriksson
This is a race that can cause RUNNING (instead of RUNNING_SYS) set on a SUSPENDED process. The effect of this race happening is probably quite benign. The bug was discovered by process_SUITE:processes_gc_trap on debug VM crashing on last assert in schedule(): /* Never run a suspended process */ ASSERT(!(ERTS_PSFLG_SUSPENDED & erts_smp_atomic32_read_nob(&p->state)));

2014-03-26Change the subtag used for maps from 0xB to 0xFKostis Sagonas
The subtag chosen for maps breaks crucial assumptions in other parts of the system, in particular the native code generation scheme used in the HiPE compiler. Therefore it is better to use 'the other' unused subtag. The main change here is the use of 0xF subtag for maps instead of 0xB. The rest of the differences are changes to and additions of comments. One more comment from my part. I noticed that the file contains the following two lines: The comment of the second line is most certainly a copy and paste error and should be appropriately fixed by the OTP developers. More importantly, it would be great if that subtag (0x7) turned out to be unused and could be used for maps instead of the 0xF one. This might turn out very handy in the future. I can elaborate on this, if needed.

2014-03-26ose: Fix bug when hunting for signal proxyLukas Larsson
Sometimes the wrong signal, i.e. a read reply, would be received from this non-selective receive.
2014-03-26ose: Implement tcp inet driver for OSELukas Larsson
The inet driver for OSE has to handle signals instead of selects and thus the wrappers for ready_input/output are a little bit different. However the majority of the inet code remains the same.

2014-03-25Fix DTrace/SystemTap-related formattingScott Lystig Fritchie
Thanks to Michał Ptaszek for bringing this embarrassing formatting error to my attention. Many DTrace/SystemTap trace strings are incorrectly truncated at 4/8 bytes, depending on the CPU word size. This patch expands the work from commit d032e097 by zheng siyao.

2014-03-21zlib: Fix adler32_combine/4 and crc32_combine/4Björn Gustavsson
Since our config.h is included in each source file in the zlib directory, we must make sure that config.h is also included every time zlib functions are called to ensure that definitions of types are consistent. zlib_drv.c did not include config.h, which caused problems on a MacOS X Leopard system. What happened was that HAVE_UNISTD_H was not defined when zlib.h was included. When unistd.h is not known to exist, the type z_off_t will be set to a long (32 bits on this platform). But when the zlib source files were compiled, HAVE_UNISTD_H was defined, unistd.h would be included, and z_off_t would be set to off_t (64 bits; defined in unistd.h). As a result of the mismatch, calls to the adler32_combine() and crc32_combine() would pass only 32 bits in the len2 argument when 64 bits were expected.
