net/ProtocolUtilities: Return EOPNOTSUPP when unhandled flags are specified.

Same as has already been done for UNIX domain sockets and TCP
(this is used in the implementation of UDP.)

net/ProtocolUtilities: Correct implementation of MSG_DONTWAIT.

We don't want to restore the timeout from a restarted syscall
if MSG_DONTWAIT has been specified.

Skip timeout computation in is_syscall_restarted case.

DatagramSocket: don't use absolute timeout 0.

* Use relative instead, or else the return value will be B_TIMED_OUT instead
of B_WOULD_BLOCK.
* This fixes bug #9734.

* Renamed net_datalink_module::send_data() to send_routed_data(), and
send_datagram() to send_data().
* Renamed DatagramSocket::SocketEnqueue() to EnqueueClone(), SocketDequeue()
to Dequeue().
* Ordered the methods in ProtocolUtilities.h according to their declaration.

* Minor cleanup.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@37867 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Corrected naming/visibility of the DatagramSocket methods (protected methods
do not get the '_' prefix, only private ones do).
* Added a "peek" argument to SocketStatus() (and generally renamed "clone" to
"peek" where it made sense).
* Implemented the base version of SocketStatus() to return the actual socket
error. This enables returning ICMP errors back to the socket user.
* Other minor cleanup.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@37712 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Some cleanup.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@37645 a95241bf-73f2-0310-859d-f6bbb57e9c96

* DatagramSocket::InitCheck() returned the sem_id instead of a status_t, causing
pings to fail (raw socket initialization) after r31079.
* Further cleanup.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@31238 a95241bf-73f2-0310-859d-f6bbb57e9c96

datagram to have the SO_BROADCAST flags set (the flag
is only needed for sending a broadcast) - fixes part of
#2065

* Removed kernel benaphores.

axeld + bonefish:
* Added syscall restart support for connect(), accept(), send(), recv(),
which are implemented via ioctl()s. The actual restart support is done
in the net stack driver's ioctl() hook. Lower layers need to correctly
deal with socket timeouts, though, for which the stack module provides
support functions.
* TCPEndpoint::_WaitForEstablished() does abort now when an error
occurred earlier, so that trying to connect to an unused port fails
immediately, as it should.
* Fixed and refactored TCP connection reset handling. The new
TCPEndpoint::_HandleReset() does the job. Got rid of
TCPEndpoint::fError.
* Fixed sequence numbers for SYNC/FINI packets.
* The former two fix the problem that connections wouldn't be closed
correctly and could even be reused when trying to connect again (as
was reproducible with svnserve + svn).
* Some style cleanup in CPEndpoint.h.



git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23984 a95241bf-73f2-0310-859d-f6bbb57e9c96

* int32_t, uint32_t are now of type "int", and no longer of type "long".
This should help to reduce the number of warnings imported code will throw
during compilation (helps a lot with tcpdump, for example).
* Since long is 64 bit on 64 bit platforms, we might want to think about doing
that change for the Haiku types int32 and uint32 as well.
* Fixed several occurences of hidden type problems.
* Fixed build of the stack and TCP under BeOS.
* Fixed incorrect typedef in socket_interface.h.
* Minor cleanup.

introduced a new helper class DatagramSocket which provides a consistent base interface and functionality for the implementation of datagram-based sockets.
