2015-11-19Fix inet:setopts/2 to take multiple raw optionsRaimo Niskanen
2015-10-26erts: Add {line_delimiter, byte()} option to inet:setopts/2Serge Aleynikov
A new {line_delimiter, byte()} option allows line-oriented TCP-based protocols to use a custom line delimiting character. It is to be used in conjunction with {packet, line}. This option also works with erlang:decode_packet/3 when its first argument is 'line'.

2015-06-09Add 'show_econnreset' TCP socket optionRory Byrne
An ECONNRESET is a socket error which tells us that a TCP peer has sent an RST. The RST indicates that they have aborted the connection and that the payload we have received should not be considered complete. Up until now, the implementation of TCP in inet_drv.c has hidden the receipt of the RST from the user, treating it as though it was just a FIN terminating the read side of the socket. There are many cases where user code needs to be able to distinguish between a socket that was closed normally and one that was aborted. Setting the option {show_econnreset, true} enables the user to receive ECONNRESET errors on both active and passive sockets. A connected socket returned from gen_tcp:accept/1 will inherit the show_econnreset setting of the listening socket. By default this option is set to {show_econnreset, false}. Note that this patch only enables the reporting of ECONNRESET when the socket is being read from. It does not report ECONNRESET (or EPIPE) when the user tries to write to a connection when an RST has already been received. Currently the TCP implementation in inet_drv.c hides all such send errors from the user in favour of returning {error, close}. A separate patch will be needed to enable the reporting of such errors.
2015-04-09Don't throw exception on prim_inet:setopt/3 errorHolger Weiß
Let gen_tcp:controlling_process/2 and inet_sctp:connect/[45] propagate prim_inet:setopt/3 errors instead of having them generate badmatch exceptions.

An erroneous lookup option is needed to trigger the bug, and that can only enter the system from a parsed file e.g .inetrc. Pinpointed by Emil Holmström

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.

2012-08-16Fix SCTP multihomingTomas Abrahamsson
Setting several ip addresses for an SCTP socket worked only for IPv4 on Linux. For IPv6 and for other for instance Solaris and FreeBSD, it failed with badarg for both IPv4 and IPv6. For the first address specified to gen_sctp:open, bind is now called, while for any following addresses, sctp_bindx is called, repeatedly, with one address at a time. Previously, sctp_bindx was called for all addresses in one go, with the addresses in reverse order, and bind was not called at all if more than one address was specified. Both Solaris and FreeBSD requires bind to have been called before calling sctp_bindx, and FreeBSD additionally allows at most one address at a time in the call to sctp_bindx. For some versions of Linux, for instance SuSE 10, the port can be 0 only for the call to bind but not for subsequent calls to sctp_bindx, so replace with the port number assigned by the operating system.

2012-01-04Fix returned error from gen_tcp:accept/1,2 when running out of portsPer Hedeland
The {error, enfile} return value is badly misleading and confusing for this case, since the Posix ENFILE errno value has a well-defined meaning that has nothing to do with Erlang ports. The fix changes the return value to {error, system_limit}, which is consistent with e.g. various file(3) functions. inet:format_error/1 has also been updated to support system_limit in the same manner as file:format_error/1.
2011-12-01sendfile caller now has to be the controlling_processLukas Larsson
This is needed because otherwise there could be scenarios when the efile driver blocks a fd and then crashes without the inet driver ever finding out. Now when the process crashes the port will close and we can cleanup in the inet driver.
