* egil/fix-getifaddrs-realloc/OTP-12445: erts: Fix getifaddrs realloc ptr mismatch
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.

2015-01-13erts: Extend driver interface with emergency_closeBjörn-Egil Dahlberg
The intention of this callback is to close all sockets associated to a port. It is closed only on crashdumps. This will currently only be used for the epmd port.

2014-07-22erts: Fix inet close on prebound fdsBjörn-Egil Dahlberg
Inet close must remove fd from select/poll without closing the fd.

2014-03-26ose: Implement tcp inet driver for OSELukas Larsson
The inet driver for OSE has to handle signals instead of selects and thus the wrappers for ready_input/output are a little bit different. However the majority of the inet code remains the same.
2014-03-26ose: Add ifdefs for HAVE_UDPLukas Larsson
2014-02-24Added support for ENEA OSELukas Larsson
This port has support for both non-smp and smp. It contains a new way to do io checking in which erts_poll_wait receives the payload of the polled entity. This has implications for all linked-in drivers.

* lukas/erts/sendfile_passive_mode_fix/OTP-11614: erts: fix bug when using passive mode and sendfile
2014-01-27erts: fix bug when using passive mode and sendfileLukas Larsson
The bug incorrectly issued driver_select when un-ignoring an fd for a socket in passive mode, which caused an incorrect error tuple to be returned when the remote end closed the connection.

2013-09-23add {active,N} socket option for TCP, UDP, and SCTPSteve Vinoski
Add the {active,N} socket option, where N is an integer in the range -32768..32767, to allow a caller to specify the number of data messages to be delivered to the controlling process. Once the socket's delivered message count either reaches 0 or is explicitly set to 0 with inet:setopts/2 or by including {active,0} as an option when the socket is created, the socket transitions to passive ({active, false}) mode and the socket's controlling process receives a message to inform it of the transition. TCP sockets receive {tcp_passive,Socket}, UDP sockets receive {udp_passive,Socket} and SCTP sockets receive {sctp_passive,Socket}. The socket's delivered message counter defaults to 0, but it can be set using {active,N} via any gen_tcp, gen_udp, or gen_sctp function that takes socket options as arguments, or via inet:setopts/2. New N values are added to the socket's current counter value, and negative numbers can be used to reduce the counter value. Specifying a number that would cause the socket's counter value to go above 32767 causes an einval error. If a negative number is specified such that the counter value would become negative, the socket's counter value is set to 0 and the socket transitions to passive mode. If the counter value is already 0 and inet:setopts(Socket, [{active,0}]) is specified, the counter value remains at 0 but the appropriate passive mode transition message is generated for the socket. This commit contains a modified preloaded prim_inet.beam due to changes in prim_inet.erl. Add tests for {active,N} mode for TCP, UDP, and SCTP sockets. Add documentation for {active,N} mode for inet, gen_tcp, gen_udp, and gen_sctp.

2012-10-08Set new peeled off SCTP socket to nonblocking socketJonas Falkevik
Peeloff feature of SCTP association creates a new socket which is not set to nonblocking. Function for receving data is shared with udp which has a default loop when reading packets which is set to 5. Calling the receive function more then once, is fine as long as there are more data to receive or socket are nonblocking. Set new peeled off socket to be nonblocking to prevent a erlang vm hangup.

2012-08-16Allow mixed IPv4 and IPv6 addresses to sctp_bindxTomas Abrahamsson
Also allow mixed address families to bind, since the first address on a multihomed sctp socket must be bound with bind, while the rest are to be bound using sctp_bindx. At least Linux supports adding address of mixing families. Make inet_set_faddress function available also when HAVE_SCTP is not defined, since we use it to find an address for bind to be able to mix ipv4 and ipv6 addresses.
