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.

To reproduce the issue, open an UDP port: 4> {ok,Port} = gen_udp:open(9000, [binary]). {ok,#Port<0.587>} 5> gen_udp:controlling_process(Port, self()). ok Simulate error: 6> 1=2. ** exception error: no match of right hand side value 2 Here is the leak: 7> inet:i().

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.

* rani/inet_gethostbyname_fixes: inet_res_SUITE: testcase fixes for legacy DNS resolver (Solaris 8) inet_res: /etc/resolv.conf: use domain as default search list inet: delayed/avoided read of /etc/resolv.conf and /etc/hosts inet_gethost_native: workaround for empty result hostname on MacOS X inet_res_SUITE: testcase fix for empty domain name inet:gethostbyname improved to parse IP strings and look up own hostname OTP-8426 The resolver routines failed to look up the own node name as hostname, if the OS native resolver was erroneously configured, bug reported by Yogish Baliga, now fixed. The resolver routines now tries to parse the hostname as an IP string as most OS resolvers do, unless the native resolver is used. The DNS resolver inet_res and file resolver inet_hosts now do not read OS configuration files until they are needed. Since the native resolver is default, in most cases they are never needed. The DNS resolver's automatic updating of OS configuration file data (/etc/resolv.conf) now uses the 'domain' keyword as default search domain if there is no 'search' keyword.
2010-02-09inet:gethostbyname improved to parse IP strings and look up own hostnameRaimo Niskanen
Now inet:gethostbyname tries to parse the hostname as an IP string first if the 'native' lookup method is not used. One can also make the IP string parsing explicit using the new 'string' lookup method, or avoid it using the new pseudo lookup method 'nostring'. In R13B04 a bug was introduced when the gethostbyname code was rewritten, so if the native resolver was used and misconfigured to not be able to look up the own hostname, inet:gethostbyname also failed. This is now fixed.
