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).

2016-02-10epmd: support IPv6 node registrationMichael Santos
Allow IPv6 nodes to register with and query epmd. On systems with IPv6 support: * epmd listens on both the IPv4 and IPv6 ANY or loopback sockets * the epmd cli client connects to epmd over the IPv6 loopback * distributed nodes started with "-proto_dist inet6_tcp" will register with epmd over IPv6 To work on IPv6 capable systems that have IPv6 support disabled, epmd ignores errors opening the socket if the protocol is not supported. Similarly, the epmd client will fall back to IPv4 if the IPv6 socket is not available. Update the minimum supported version of Windows to Windows Vista to support IPv6.
