Comparison of exact terms could cause faulty term tests. This was caused by a faulty (too small) internal type. Symptom: -1 = erts_internal:cmp_term(2147483648,0). %% wrong Correct: 1 = erts_internal:cmp_term(2147483648,0). Reported-by: Jesper Louis Andersen

2015-02-26hipe: change mfa_info_table lock to rwmutexMikael Pettersson
The hipe_mfa_info_table lock is currently a mutex, causing unnecessary contention and serialization of lookups for apply-like constructs. - change the lock from a mutex to an rwmutex - split hipe_get_na_nofail_locked into a "try" path which only needs a read lock, and a "slow" path which requires a write lock - reimplement hipe_get_na_nofail (used by apply ops etc) to first call the "try" path with a read lock, and if that fails the "slow" path with a write lock - reimplement hipe_get_na_nofail_locked (used by maintenance code) to call the "try" path and then optionally the "slow" path, but without taking locks since its caller already has the write lock - adjust remaining lock ops to take/release full write lock - use _rwlocked as suffix on functions requiring a write lock - change hipe_mfa_get_trampoline to call get_locked not put_locked, allowing it to take a read lock instead of a write lock - change hipe_find_mfa_from_ra() to only take a read lock

2015-02-14don't leave a heap hole in erts_bs_get_integer_2Mikael Pettersson
Reset p->htop in the oversize bignum error case to avoid leaving a hole in the heap, which would crash the debug emulator.
2015-02-04don't create oversize bignums in binary matchingMikael Pettersson
Bignums are artifically restricted in size. Arithmetic and logical operations check the sizes of resulting bignums, and turn oversize results into system_limit exceptions. However, this check is not performed when bignums are constructed by binary matching. The consequence is that such matchings can construct oversize bignums that satisfy is_integer/1 yet don't work. Performing arithmetic such as Term - 0 fails with a system_limit exception. Worse, performing a logical operation such as Term band Term results in []. The latter occurs because the size checking (e.g. in erts_band()) is a simple ASSERT(is_not_nil(...)) on the result of the bignum operation, which internally is [] (NIL) in the case of oversize results. However, ASSERT is a no-op in release builds, so the error goes unnoticed and [] is returned as the result of the band/2. This patch addresses this by preventing oversize bignums from entering the VM via binary matching: - the internal bytes_to_big() procedure is augmented to return NIL for oversize results, just like big_norm() - callers of bytes_to_big() are augmented to check for NIL returns and signal errors in those cases - erts_bs_get_integer_2() can only fail with badmatch, so that is the Erlang-level result of oversize bignums from binary matches - big_SUITE.erl is extended with a test case that fails without this fix (no error signalled) and passes with it (badmatch occurs) Credit goes to Nico Kruber for the initial bug report.

2015-01-29erts: Fix getifaddrs realloc ptr mismatchBjörn-Egil Dahlberg
When a buffer was exhausted and subsequently a realloc, we could get an invalid pointer. For this to occur we would need to have a realloc to lower adresses. The symptom would be garbage returned from erlang:port_control(Port, 25, []) (prim_inet:getifaddrs(Port) resulting in a badarg) or a segmentation fault.

closefrom() was only used in the vfork() case before, now also used in the fork() case.
