My man pages has the following to say about the return value of recv:

    These calls return the number of bytes received, or -1 if an error occurred.

    For TCP sockets, the return value 0 means the peer has closed its half side of the connection.

This means that it's absolutely fine to read 0 bytes when using e.g. UDP socket.

However, the Network.Socket.recv function always throws an exception upon reading 0 bytes regardless of the protocol family.

This could certainly happen on other operating systems as well, though I've not tested others. Whether it happens or not could even vary from release to release.

I've verified that telnet 127.0.0.1 4444 produces a ""connection refused"" message, but telnet ::1 4444 connects and displays ""Bye!""

I'd go so far to say that this is a bug. At best, one could argue that this behaviour is not entirely intuitive.

I propose that we (re-?)define `PortID`'s `PortNumber` constructor to refer only to IPv4 protocol ports, and add a new `PortNumber6` constructor for IPv6 ports.

Another option would be to do force `PortNumber` always to bind to IPv4, but not add `PortNumber6`. I prefer this less because we should be encouraging the use of IPv6, and because having `PortNumber6` serves as obvious documentation for what `PortNumber` and `PortNumber6` do.

A third option would be to attempt to listen on both IPv4 and IPv6, when both are available, but this sort of thing is fraught with many problems, the details of which are much more than I'd want to get into in this bug report. 

----

I saw exactly the same problem on FreeBSD.

    I propose that we (re-?)define `PortID`'s `PortNumber` constructor to refer only to IPv4 protocol ports, and add a new `PortNumber6` constructor for IPv6 ports.

That sounds highly reasonable. I prefer that way.

----

This sounds like a peculiarity of the BSD networking stack. On Linux, the code correctly chooses a wildcard address that responds to both IPv4 and IPv6 traffic.

I'd strongly suggest that a BSD user dig into the platform-specific problem. Suggesting an API change without any investigation of the underlying issue is not the right approach.

----

Actually, the linux code incorrectly binds to both; this opens up a security problem, though I can't remember the exact details right now. This is exactly the reason for the default sysctl setting of ""net.inet6.ip6.v6only = 1"", IIRC.

----

Here is a document discussing the security issues with IPv4-mapped addresses:

    ftp://ftp.itojun.org/pub/paper/draft-itojun-v6ops-v4mapped-harmful-01.txt

I'd say we definitely don't want to have to force people to enable this just to use Network, which is in the end supposed to make life simpler for basic networking.

----

The Linux behaviour does not appear to me to be incorrect, and the document to which you refer is concerned with threats due to the use of IPv4-mapped addresses on the wire.

The code in the `Network` module uses the `Network.Socket` code for its implementation. There are currently several knobs for controlling `getAddrInfo` that it does not use. Perhaps if you read up on a few of them and try them out, you might find a behaviour that you could then propose as more desirable.

3,Active Tickets,17,recv and recvBufFrom in network should accept 0 for a length when currently it throws an exception,network,,,defect,,new,2009-07-17T16:11:27Z+0100,2009-09-26T19:36:31Z+0100,"See the email below for context, Johan is fixing network-bytestring, which suffers from the same thing currently.

To: Johan Tibell <johan.tibell@gmail.com>  
Johan,
 
I am coming upon a behavior with recv that I find a bit strange. When you pass in a length of 0 as the second argument, it raises an exception. Here is the relevant code excerpt from network-bytestring-0.1.2.1:
 
recv :: Socket         -- ^ Connected socket
     -> Int            -- ^ Maximum number of bytes to receive
     -> IO ByteString  -- ^ Data received
recv (MkSocket s _ _ _ _) nbytes
    | nbytes <= 0 = ioError (mkInvalidRecvArgError ""Network.Socket.ByteString.recv"")
    | otherwise   = createAndTrim nbytes $ recvInner s nbytes

Now, 0 is definitely an unuseful value for this function, but it is definitely not an invalid one which justifies raising an exception. When I pass 0 for the length I am simply saying ""receive nothing"". I believe it should be changed like so:
 
recv :: Socket         -- ^ Connected socket
     -> Int            -- ^ Maximum number of bytes to receive
     -> IO ByteString  -- ^ Data received
recv (MkSocket s _ _ _ _) nbytes
    | nbytes < 0  = ioError (mkInvalidRecvArgError ""Network.Socket.ByteString.recv"")
    | nbytes == 0 = return empty
    | otherwise   = createAndTrim nbytes $ recvInner s nbytes

When I tried recvFrom it has the same semantics (not allowing 0). recvFrom uses a function recvBufFrom from Network.Socket. Now if my point of view that 0 should not be an error case is correct, then this means both network and network-bytestring are wrong. 
 
What do you think? Am I wrong? Is this how recv is supposed to behave on a posix socket?

Hi,

What I turned up after some googling and looking at the Linux sources seems to support that a zero length shouldn't be an error. I'll fix that when I get home. However, I do think the syscall to recv should be made even if the length is zero. The reasoning is that a user might want this behavior to e.g. force EOF on the socket.


recv :: Socket         -- ^ Connected socket
     -> Int            -- ^ Maximum number of bytes to receive
     -> IO ByteString  -- ^ Data received
recv (MkSocket s _ _ _ _) nbytes
    | nbytes < 0  = ioError (mkInvalidRecvArgError ""Network.Socket.ByteString.recv"")
    | otherwise   = createAndTrim nbytes $ recvInner s nbytes


I can fix network-bytestring quite easily but could you file a bug at http://trac.haskell.org/network ?

This is because under the hood, it is calling c_connect, an unsafe foreign import:

{{{

  c_connect :: CInt -> Ptr SockAddr -> CInt{-CSockLen???-} -> IO CInt
}}}

Unsafe foreign calls block the whole runtime system.  Safe foreign calls block only the current thread (but cannot be interrupted by exceptions).

I tested it on Windows with network-2.3.0.8, and Network.Socket.connect does in fact block the whole program.  When I changed unsafe to safe and recompiled, it did not block the whole program.

It seems clear that c_connect should be a safe foreign import, at least on Windows with -threaded.  Are there any other foreign calls marked safe that could potentially block on Windows?",joeyadams

4,Active Tickets,23,`setSocketOption' fails with `Linger' option,network,,,defect,,new,2009-12-13T21:47:04Z+0000,2009-12-13T21:47:04Z+0000,"[http://hackage.haskell.org/packages/archive/network/2.2.1.5/doc/html/Network-Socket.html#v%3AsetSocketOption setSocketOption]
uses FFI binding to ''setsockopt(2)'':

{{{
foreign import CALLCONV unsafe ""setsockopt""
  c_setsockopt :: CInt -> CInt -> CInt -> Ptr CInt -> CInt -> IO CInt
}}}

This binding treats OPTVAL (4th argument) as a pointer to `int'. This
is fine in most cases excepting the one when `SO_LINGER' option is
being set. In the latter case OPTVAL must be a pointer to `struct
linger'. (See [http://www.gnu.org/s/libc/manual/html_node/Socket_002dLevel-Options.html libc manual].)

Haskell programs that try to set SO_LINGER socket option will
successfully compile but '''fail in runtime''':

{{{
$ runhaskell socket-linger.hs || echo X
$ runhaskell -DLINGER socket-linger.hs || echo X
socket-linger.hs: setSocketOption: invalid argument (Invalid argument)
X

$ gcc -g -Wall -W -o /tmp/1 socket-linger.c && /tmp/1 || echo X
$ gcc -g -DLINGER_AS_INT -Wall -W -o /tmp/1 socket-linger.c && /tmp/1 \

}}}

(See the code of [http://hpaste.org/fastcgi/hpaste.fcgi/view?id=14125#a14125 socket-linger.hs]
and [http://hpaste.org/fastcgi/hpaste.fcgi/view?id=14125#a14127 socket-linger.c].)

Still, the necessity of `SO_LINGER' option is
[http://www.developerweb.net/forum/archive/index.php/t-2982.html controversial].
I think we better just remove `Linger' constructor from
`Network/Socket.hsc'.
