2014-05-14Fix efile_openfile() to handle stat() failureMikael Pettersson
If the initial stat() fails then efile_openfile() will still proceed to open() the file. If that succeeds and the caller passed a non-NULL pSize, then it will copy bogus data from the statbuf into *pSize. This has been observed to cause file:read_file/1 to return truncated file data with no error indication. The use case involved a large file system mounted via NFS, with some directories containing large number of files, and NFS mount options that allow the NFS client to return EIO if the NFS server does not respond quickly enough. Depending on the caching state of the client and server machines, a few stat() calls (fewer than 1 per 10 million) would take long enough to trigger EIO errors, but subsequent open() calls would succeed, and read_file/1 would return truncated data. This sequence of events has been observed via "strace" on beam.smp. Signed-off-by: Mikael Pettersson <[email protected]>

2014-04-29Fix race between ETS table deletion and unfixationSverker Eriksson
Symptom: VM crash running mnesia_SUITE Scenario: Process A terminates while still having fixed table T and process B "at the same time" deletes table T with ets:delete/1 or by terminating. Problem: A table scheduled for deallocation do only have a valid 'common' part. The unfix-table-at-process-exit code tried to read the hash-specific part of such a table. Solution: Must back off if DB_DELETE flag is set. Since: R16B

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.

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.
