cdc00dadfc * Added optional {send,read}_data_no_buffer() hooks to the protocol
module interface. They directly operate on iovecs and thus allow
  protocols that don't need it to avoid the creation of a net_buffer.
* Adjusted the socket module to support the new hooks. If they are
  present, they will be chosen over the old hooks.

49e00d1f99 Moved the container management for ancillary data from the net_buffer
module to the stack module. There's a dedicated struct
ancillary_data_container, now. One can just set the container on a
net_buffer.

45e95a057f * Removed the old net_stack driver code, and the kernel socket interface.
* Also removed the header files that belong to those files.
* Only kept the userland_ipc.h header for now, to remember us about the
  former userland server driver (that I also removed - it can always be
  resurrected from SVN if needed).

97cdbb548e Added support for sending/receiving ancillary data. The protocol modules
have two more optional hooks for attaching supplied ancillary data to a
net_buffer and for processing received ancillary data. Not sure, if that
is flexible enough for all kinds of ancillary data, but it is for
SCM_RIGHTS and also should for SCM_CRED[ENTIAL]S (if we ever decide to
implement one of those) -- don't know any other types on other protocol
levels.

62d7da1f45 Added support for attaching ancillary data to a net_buffer. It's a naive
implementation ATM, since it malloc()s the required memory.

75015ff525 * Renamed THREAD_FLAGS_IOCTL_SYSCALL to THREAD_FLAGS_SYSCALL,
syscall_restart_ioctl_is_restarted() to syscall_restart_is_restarted,
  IoctlSyscallFlagUnsetter to SyscallFlagUnsetter, and
  IoctlSyscallRestartWrapper to SyscallRestartWrapper, as they are no
  longer only used for ioctl().
* Removed unused syscall_restart_ioctl_handle_post().
* Made SyscallRestartWrapper a lot fancier. Instead of storing a
  reference to the result value, it stores the value itself, and it
  features all the interesting operators that make it appear like that
  value. This simplifies the use of the class quite a bit.
* THREAD_FLAGS_SYSCALL is now set for all socket function and the
  read[v](), write[v]() syscalls.
* Added is_syscall() function and net_stack hook to the net stack.
* Removed "kernel" parameter from all net_stack_interface and net_socket
  module hooks. They aren't need any longer, since is_syscall() can be
  used instead.

df50f7a9b4 * Changed the way the socket functions work:
- The net_stack driver is no longer used. Instead we have a kernel
    module which is directly used by syscall implementations in the
    kernel. I.e. we no longer tunnel those functions through ioctls, but
    have normal syscalls.
  - Removed the superfluous net starter module.
  - Implemented the FDTYPE_SOCKET type file_descriptors, that is sockets
    are no longer vnode based.
  - Adjusted libnetwork (the socket function implementations)
    accordingly.
  - Adjusted netstat accordingly.
* Socket module:
  - Implemented socketpair().
  - Added "kernel" parameter to the control hook. Quite a few more hooks
    would actually need the parameter, but I didn't change those yet,
    since that would probably also require changes to the protocol
    module interface.

b5a5aebc90 * Added a set_to_defaults() function to the address module: it can be used
to retrieve the default settings for the netmask/broadcast depending on the
  specified address/netmask.
* interface_protocol_control() now uses this to reset the broadcast/netmask
  to their default values on SIOCSIFADDR resp. the former only on
  SIOCSIFNETMASK.
* This fixes bug #1861.

058494285a 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.

6f58064f10 * Added flags field in net_protocol_module_info; there is currently a single
defined flag: NET_PROTOCOL_ATOMIC_MESSAGES.
* socket_send() now honours NET_PROTOCOL_ATOMIC_MESSAGES and returns either
  EMSGSIZE if the data to be send is larger than net_socket::send::buffer_size,
  or divides the data in appropriately sized chunks.
* This fixes sending >=64K over a TCP socket at once (TCP would just have
  returned an error in that case).
* TCP now overrides the default send buffer size (to 32768 for now).

15ab0bcf01 * 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.

73f1548be1 some getsockopt/setsockopt and multicast fixes.
* allow an ipv4 bind() to a multicast address.
 * bumped getsockopt/setsockopt kernel driver buffers to 256 bytes to at least handle structures which take one sockaddr_storage.
 * convert generic multicast delta API names to IPv4 ones before handling the specific option.
 * changed ipv4_getsockopt/ipv4_setsockopt a bit as the code gcc 2.95 was generating was a bit too funky.
 * properly pass setsockopt/getsockopt to handling protocols.

624c52d8b7 ARP now queues packets while resolving a destination instead of blocking on send_data(). This fixes several issues:
- TCP now behaves correctly when receiving new connections as its SYN/ACK is queued, or if lost correctly retransmitted when the peer resends a SYN.
 - The first ICMP Replies from an external on-link host pinging Haiku are no longer lost.
 - Reduced the number of ARP messages Haiku needs to generate until resolving an entry.

 - fixed an issue with UDP where the wrong source address could be used in the calculating the checksum.
 - changed ipv4_print_address to use the more common 0.0.0.0 format.

 - ICMP is now able to reply to ICMP Echo Requests which were split across data nodes.
 - in split_buffer(), make sure we were able to trim() the new buffer before damaging the original one.

  - Maybe we should add something like a public net_protocol_implementation which maintains a fifo and a benaphore? With the fifo using the structure's lock instead of maintaining it's own.
