2014-08-08erts: Fix neg int overflow when sint is min sizeLukas Larsson
When INT64_MIN is the value of a Sint64 we have to first cast it to an Uint64 before negating it. Otherwise we get an integer overflow which is undefined behaviour and in gcc 4.9 this results in -0 instead of -9223372036854775808 in gcc 4.8.

2014-08-05Fix abort of nosuspend-tasks in erts_port_task_schedule()Rickard Green
The counter for the amount of outstanding data in the port queue became inconsistent when aborting nosuspend-signals in erts_port_task_schedule(). This since the counter was subtracted by the data size of the signal although the data size had never been added to it. This inconsistency caused the port queue to remain in a busy state forever.

2014-07-02Properly handle SINT_MIN in small_to_big()Anthony Ramine
As there is no overflow for signed integers, -SINT_MIN is undefined behaviour and the cast to unsigned needs to happen before negation. SINT_MIN denotes the minimum value that can be stored in the Sint type. beam/big.c:1512:6: runtime error: negation of -9223372036854775808 cannot be represented in type 'Sint' (aka 'long'); cast to an unsigned type to negate this value to itself

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
