* raimo/type-posix-0-overhaul/ERL_550/OTP-14019: Update types for posix error codes
2018-03-26Update types for posix error codesRaimo Niskanen
I have read the man pages for most socket and file operations on recent Linux, FreeBSD, OpenBSD and Solaris 10 and noted the possible error codes. Which error codes that are possible for file operations have been updated in file:posix/0. Error codes for socket operations in inet:posix/0. The latter refers to the former so it is a superset, assuming that e.g sendfile and AF_UNIX socket operations could cause socket operations to return any file error code. That is not entirely true, but could be, especially in the future. Added to file:posix/0 are: ebadmsg edeadlk edeadlock eftype emultihop enobufs enolck enolink enosr enostr enosys eopnotsupp eoverflow erange etxtbsy Added to inet:posix/0 are all but: exbadport exbadseq file:posix() These are still possible according to erl_posix_str.c, but are not in file:posix/0 nor in inet:posix/0, and many of them are not file nor inet related, but some might be: e2big eadv ealign ebade ebadfd ebadr ebadrpc ebadrqc ebadslt ebfont echild echrng ecomm edirty edom edotdot eduppkg eidrm einit eisnam elbin el2hlt el2nsync el3hlt el3rst elibacc elibbad elibexec elibmax elibscn elnrng enavail enet enoano enocsi enodata enoexec enonet enosym enotempty enotnam enotuniq eproclim eprocunavail eprogmismatch eprogunavail erefused eremchg eremdev eremote eremoteio eremoterelease erpcmismatch erremote eshutdown esrmnt esuccesss etime etoomanyrefs euclean eunatch eusers eversion exfull sysnotready vernotsupported ediscon enomore ecancelled einvalidproctable einvalidprovider eproviderfailedinit syscallfailure service_not_found type_not_found e_no_more e_cancelled unknown

2016-01-12Assign externally open fd to gen_tcp (UDS support)Serge Aleynikov
When a AF_LOCAL file descriptor is created externally (e.g. Unix Domain Socket) and passed to `gen_tcp:listen(0, [{fd, FD}])`, the implementation incorrectly assigned the address family to be equal to `inet`, which in the inet_drv driver translated to AF_INET instead of AF_LOCAL (or AF_UNIX), and an `einval` error code was returned. This patch fixes this problem such that the file descriptors of the `local` address family are supported in the inet:fdopen/5, gen_tcp:connect/3, gen_tcp:listen/2, gen_udp:open/2 calls

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.

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.
