2016-04-01erts: Fix race for process_flag(trap_exit,true)Sverker Eriksson
and a concurrent exit signal. We now actually guarantee that the process will not die from exit signal *after* the call to process_flag(trap_exit,true) has returned. The race is narrow and probably quite hard to observe even if you manage to provoke it. Has only been confirmed with the help of return trace and a sleep in send_exit_signal(). Solution: Seize status lock to prevent send_exit_signal() from reading an old status (without TRAP_EXIT) and then writing PENDING_EXIT after TRAP_EXIT has been set by process_flag_2().

2016-03-02Skips any sockets with unsupported protocols.Ingela Anderton Andin
Patch from end of PR 864 Fixes problem reported in the PR by jeckersb In this error case, a negative file descriptor is now saved at listensock[i], which leads to a buffer overflow later on at https://github.com/msantos/otp/blob/epmd-IPv6-node-reg2/erts/epmd/src/epmd_srv.c#L498 when calling FD_ISSET(listensock[i],&read_mask). To reproduce this: Completely disable IPv6 with ipv6.disable=1 on the kernel command line Build with fortified code (RHEL/CentOS default): CFLAGS='-O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong --param=ssp-buffer-size=4 -grecord-gcc-switches -m64 -mtune=generic -fno-strict-aliasing'

2016-02-24erts: Make erlang:halt() accept bignums as StatusSverker Eriksson
Just mask away the high bits to get a more tolerant erlang:halt that behaves the same on 32 and 64 bit architectures.
2016-02-24erts: Change erl_exit into erts_exitSverker Eriksson
This is mostly a pure refactoring. Except for the buggy cases when calling erlang:halt() with a positive integer in the range -(INT_MIN+2) to -INT_MIN that got confused with ERTS_ABORT_EXIT, ERTS_DUMP_EXIT and ERTS_INTR_EXIT. Outcome OLD erl_exit(n, ) NEW erts_exit(n, ) ------- ------------------- ------------------------------------------- exit(Status) n = -Status <= 0 n = Status >= 0 crashdump+abort n > 0, ignore n n = ERTS_ERROR_EXIT < 0 The outcome of the old ERTS_ABORT_EXIT, ERTS_INTR_EXIT and ERTS_DUMP_EXIT are the same as before (even though their values have changed).
