2017-02-20Ensure prim_eval:'receive' wont clobber def_arg_reg[0]Rickard Green
def_arg_reg[0] is used for storage of timeout instruction when a 'receive after' is executed. When a process was scheduled out inside prim_eval:'receive'/0 due to a function call, def_arg_reg[0] was overwritten due to storage of live registers. prim_eval:'receive'/2 now calls arg_reg_alloc/0 which bumps all reductions and then calls arg_reg_alloc/7 which will cause an allocation of a new arg_reg array since def_arg_reg only can hold 6 values. This ensures that the timeout instruction in def_arg_reg[0] used for the timeout wont be overwritten.

2017-01-23erts: Fix binary_to_term for compressed and zlib >= v1.2.9Sverker Eriksson
Problem: z_stream was incorrectly copied with memcpy which just happened to work with zlib < v1.2.9. Solution: Avoid copying z_stream.

2017-01-12erts: Fix race bug between export fun creation and code loadingSverker Eriksson
Symptom: SEGV crash on ARM in delete_code() -> export_list(). Could probably happen on other machines as well. Problem: Staging export table was iterated in an unsafe way while an entry was added for a new export fun. Solution: Correct write order and some memory barriers.

2016-11-08Revert "Check libsctp for sctp funcs in configure.in"Raimo Niskanen
This reverts commit 52fae83743a6e84d719f4f82fe45e6e0efdbd6f0: Check libsctp for sctp funcs in configure.in Call AC_CHECK_LIB before calling AC_CHECK_FUNCS to check for functions in libsctp. Otherwise AC_CHECK_FUNCS will not link with libsctp to see if function exists. Reverting to the old behaviour of not checking for libsctp before checking for sctp functions. Then it works on Linux by loading libsctp and looking up the symbols i runtime, and it works on FreeBSD since there is no separate libsctp to link against - the functions are part of the default system libraries.

2016-11-05Fix performance bug in erl_prim_loader:get_modules/{2,3}Björn Gustavsson
The erl_prim_loader:get_modules/{2,3} functions were introduced in cd283583f8. Unfortunately, while the functions worked correctly, there was a bug in that many garbage maessages would be sent to the erl_prim_loader process. The number of extra messages depended on both the length of the code path and of the number of modules that were fetched. The messages were ignored and ultimately discarded, causing no harm except for a performance degradation and increase of the heap size for the erl_prim_loader process. The following functions were hit by the performance bug: code:atomic_load/1 code:ensure_modules_loaded/1 code:prepare_loading/1
