2007), and Yin Qiu (GSoC 2008). And even though I needed to rewrite pretty
much all of it because of the countless bugs and problems it had, it still
shares the same architectural problems of introducing a domain dependent
error mechanism to the upper layers, and needing the
net_buffer::network_header hack. This I will rework later.
* net_buffer's append_size(), and prepend_size() will now gracefully handle
buffers without a data node.

directly here), I made only a few style changes:
* introduced 'has_broadcast_address' field in
struct net_address_module_info
- REVIEW: the name, and the status of this field for UNIX and L2CAP
families
* ipv6 address family support
* ipv6 address printing
* ipv6 protocol support
* ipv6 multicast support
- TODO: add and remove multicast routes in a more proper way
- TODO: support MLD
* ipv6 datalink protocol support
* icmpv6 protocol support (EchoRequest and EchoResponse messages)
* ipv6 neigbor discovery protocol support
(Advertisement and Solicitation messages)
- TODO: only the very basic support is present,
the protocol state machine is by no means completed
- TODO: replying to Solicitation does not work too good ATM
(visible, when pinging Haiku from outside)
* added Jenkin's hash algorith
* minor changes in existing IPv4 code - cleanup function
ipv4_get_loopback_address(), written by myself
* add tests: raw, udp, tcp/udp, mullicast sender
* add 'hoplimit' field in struct net_buffer
- TODO: this is just a hack, more generic approach would be better.
* add 'receive_data' function pointer in
struct net_datalink_protocol_module_info
- TODO: this is also more like a hack, to support information
passing from ICMPv6 to IPv6_datagram level.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@37604 a95241bf-73f2-0310-859d-f6bbb57e9c96
* fix connecting to INADDR_ANY work for tcp (effectively will
connect to INADDR_LOOPBACK)
* add same behaviour to udp
* move some ipv4-specific code out of tcp into ipv4 address module
* bind() and connect() now reject addresses from non-matching
families
* myself: minor cleanup in udp.cpp with respect to 80 chars limit
Closes#5716 - many thanks!

* Instead, added a new function is_local_link_address() which returns the
interface with the matching link level address, and can additionally test
for unconfigured interfaces.
* Merged the two versions of fill_sockaddr_in() together in ipv4.cpp.
* ipv4 now uses the new is_local_link_address() function to figure out whether
the received packet should be processed or not. This should fix a few DHCP
issues with multiple and configured interfaces as recently explained on the
mailing list.

Bosii is a transcription of 802.11. It is a work-in-progress title to
point out parts of the wlan stack which are still in an experimental state.
For example the control codes within bosii_driver.h are moving targets.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@34349 a95241bf-73f2-0310-859d-f6bbb57e9c96
* added new protocol method process_ancillary_data_no_container() that does not
need a container to fill the cmsghdr data.
* Added support for the IP_RECVDSTADDR option using this call.
* Implemented support for IP_MULTICAST_IF.

socket could be acquired, ie. when its reference count is 0, it cannot be
acquired anymore. This requires the protocol to do proper locking, though.
* The TCP EndpointManager now checks the return value of acquire_socket(), and
only returns the endpoint if that succeeded.
* This fixes bug #2197.
* Minor cleanup.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@30363 a95241bf-73f2-0310-859d-f6bbb57e9c96

parent.

- This means that buffers with a initial size of 0 work now.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@29006 a95241bf-73f2-0310-859d-f6bbb57e9c96
- Default buffer size is now set to 1 instead of 0, which would cause the
construction without a given size to fail.
- Added copy constructor.
- Changed _GrowToFit() to have a boolean parameter to indicate if we want
to resize the buffer to an exact size. Used by the copy constructor.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@28924 a95241bf-73f2-0310-859d-f6bbb57e9c96
- Will be used by the new (R5 compatible) NetBuffer class.

old invalid user listeners yet, though (ie. if a team dies).
* Implemented userland network monitor functions.
* Added a few notifications to the network stack, even though this part isn't
complete yet (especially notify_interface_changed()).
* Added optional debug output to the notifications module.
* Added the module to the image, it basically works now (tested).
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@28825 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Compiles, but doesn't work at all yet. For those who wonder: the networking
notifications are put into a separate module, so that the network stack can
be unloaded without losing connection, IOW user applications will continue
to retrieve notifications when the stack is loaded again.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@28790 a95241bf-73f2-0310-859d-f6bbb57e9c96
* This makes it possible to select a specific device, even if no interface
has been configured for it yet. To make it work, each interface now has a
private direct route which will be returned if a socket is bound to a device.
* This will be used for example in DHCP to make it work when more than one
adapter is attached.

* wait_for_timer() now detects if it has been called from within the timer
execution thread, and will return in error instead of waiting for itself
forever. This fixes bug #2682.

wait_for_timer() function.
* Moved the internal Fifo class into utility.cpp - we should probably just
remove it again.
* Fixed uninit_timers() so that it would even work in combination with the
timer thread if there are timers left to be scheduled.
* Minor cleanup.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@26980 a95241bf-73f2-0310-859d-f6bbb57e9c96
struct sockaddr_in - the real culprits were BNetAddress::GetAddr(sockaddr_in&)
and BNetAddress::SetTo(const sockaddr_in&):
* moved check_r5_compatibility() into r5_compatibility.h to make that function
available to BNetAddress, too
* adjusted sockaddr_in-handling methods of BNetAddress to deal with R5-addresses
if in compatibility mode
* removed is_r5_sockaddr() again, since it is no longer needed
With this less hacky solution, Beam, NetPositive, NetworkTime and Vision still work. So, there's hope that the R5 compatibility layer is now complete.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@26377 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Added "struct" to ancillary_data_container which fixes the build of the
Bluetooth h2generic driver.
---
* Updated license header.
* Honour 80 char line width.

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.

ancillary_data_container, now. One can just set the container on a
net_buffer.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25292 a95241bf-73f2-0310-859d-f6bbb57e9c96
* 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).
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25045 a95241bf-73f2-0310-859d-f6bbb57e9c96
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.

implementation ATM, since it malloc()s the required memory.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@24940 a95241bf-73f2-0310-859d-f6bbb57e9c96
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.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@24914 a95241bf-73f2-0310-859d-f6bbb57e9c96
- 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.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@24908 a95241bf-73f2-0310-859d-f6bbb57e9c96
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.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@24170 a95241bf-73f2-0310-859d-f6bbb57e9c96
* 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
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).
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23915 a95241bf-73f2-0310-859d-f6bbb57e9c96
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.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22643 a95241bf-73f2-0310-859d-f6bbb57e9c96
* 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.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20939 a95241bf-73f2-0310-859d-f6bbb57e9c96
- 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.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20712 a95241bf-73f2-0310-859d-f6bbb57e9c96
- check if the destination address is specified in IPv4's SendData()
- minor cleanups to IPv4's TRACE()s.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20681 a95241bf-73f2-0310-859d-f6bbb57e9c96
- made the ipv4 raw, udp and link protocols use DatagramSocket.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20672 a95241bf-73f2-0310-859d-f6bbb57e9c96
- IPv4 now assumes the addresses it is supplied in send_routed_data are already the appropriate ones.
- made the Data(), operator* and operator-> methods in NetBufferFieldReader const so we can use them in the same expression as the constructor.
- 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.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20660 a95241bf-73f2-0310-859d-f6bbb57e9c96
- introduced base NetBufferFieldReader which deals with obtaining a continuguous field to deal with.
- renamed Detach() to Sync() to better express the fact that we may be writing to the buffer.
- Fixed IPv4's and ICMP's checksum calculation as it assumed the underlying header was contiguous.
- 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.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20657 a95241bf-73f2-0310-859d-f6bbb57e9c96
- Properly flag sockets using non-blocking connects() when in SYN SENT.
- and when in LISTEN, we should use the socket's connection queue size.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20631 a95241bf-73f2-0310-859d-f6bbb57e9c96
- Introduced public net_device_monitor.
- Changed the link protocol to maintain a lock per instance instead of inside the FIFO. Now all of the link instance data is protected.
- Adapted the link protocol to use net_device_monitor.
- Introduced a private Fifo class which doesn't maintain it's own lock.
- 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.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20614 a95241bf-73f2-0310-859d-f6bbb57e9c96
- changed the link, ipv4 and udp modules to use fifo_socket_enqueue_buffer
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20587 a95241bf-73f2-0310-859d-f6bbb57e9c96
- changed the socket module to use thew new RECEIVE/SEND in all forms of recv() and send()
- changed libnetwork to use the new RECEIVE/SEND
- remove transfer_args processing from strace since the structure was removed
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20581 a95241bf-73f2-0310-859d-f6bbb57e9c96
* The device interface list now uses class DoublyLinkedList instead of struct list.
* Implemented SIOC[SG]IFMEDIA for setting (not supported by any device yet), and
retrieving the device media information.
* Fixed a locking bug in list_domain_interfaces().
* Added new stack function device_link_changed() that should be called in case the
link state (media) changed.
* The ethernet device module now spawns a thread and will periodically check the media
state of all ethernet devices that support this (if any).
* Minor cleanup.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20546 a95241bf-73f2-0310-859d-f6bbb57e9c96
it might also be a good idea to change the constants to better match the usual
style.
* Added a BSD-style if_media.h.
* Added interface flags IFF_LINK, IFF_AUTO_CONFIGURED, and IFF_CONFIGURING. The
former will be set automatically by the stack, the rest will be set by the
net_server depending on the current state.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20535 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Added an "owner" field that stores the team which created the socket (for netstat only);
we would need a different storage for SIGURG if we ever want to support that.
* Improved netstat address output: now prints "*" instead of INADDR_ANY.

within the library - theoretically, this mechanism could be extended to
turn the compatibility layer on and off based on the images that call the
functions (allowing to mix R5 and BONE network add-ons in a single executable).
This change fixes R5 networking apps such as Vision, and NetworkTime (both
now seem to work fine under Haiku).

* The ipv4_fragment is no longer needed, as we can use the above field there
as well - this saves one extra allocation per received fragment.

* Completey dropped the old select code, as well as any R5 compatibility stuff. If
we ever need it again, it's still in SVN history.
* The socket module was put in uninit_driver() for no reason.
* Minor cleanup.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19236 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Added some missing result checks, mostly for allocations.
* Fixed a wrong precendence with the ?: operator
* Some minor cleanup.
* Renamed sBufferModule to gBufferModule - the header expects it to be a global,
so it should be named like one.
