network: Do not apply ethernet headers for loopback devices.

This reverts large portions of e2b57695fc3ec43cad099ab3dd93bdd99e052761
and all of 4e9653027d9094f4d57fd294d46ce6eb461b697f, and adjusts
the "tunnel" and "loopback_frame" handlers appropriately.

Initially, this logic was added so that libpcap continued working;
however, it seems that we can change some of the Haiku-specific code
in libpcap and have it continue to operate without requiring such
ethernet headers to be appended.

Fixes #18801.

network: Update device statistics (mostly) in the stack.

We bypass device logic in datalink_send_routed_data() in the case
of RTF_LOCAL, so if we don't update the stats there, they'll never
get updated. Furthermore, there's places packets can be dropped
inside the device reader thread. So, we might as well consolidate
the stats-updating logic and get it out of drivers.

(The only remaining case where drivers need to update stats is when
they drop a packet in receive(), as the stack can't tell when an error
from receive() is due to a dropped packet or not.)

Fixes a potential leak on packet drops in the device reader thread,
and fixes loopback statistics for TCP/UDP/etc.

net_stack: for local delivery, also capture packets when enabled

the packet capture expects frames: prepend an ethernet header for the capture.

loopback_frame: apply an ethernet header for packet capture

net/if: Drop ifmediareq and just use the regular ifreq for SIOCGIFMEDIA.

This was introduced into the main API in 2010 (d72ede75fb252c24c8a5fcc39395f9ae1c202322),
but was actually only fully used for the past month (c2a9a890f3ac7795602d11c0edaa20ac2db48202)
when SIOCGIFMEDIA was supported for all *BSD drivers and not just WiFi.
Most userland consumers of this structure did not use it correctly,
as was the case in #17770, and only worked because in the fallback case
the network stack just treated it as if it were an ifreq.

Nothing actually used the ifm_count/ifm_ulist (though tentative APIs
were exposed for it) as noted by previous commits; and the fact that
Haiku's IFM_* declarations are so spartan makes most of the returned
values unintelligible to userland without using FreeBSD compat headers.

If, in the future, we decide to implement ifmedia listing and selection
properly, that should likely be done with separate ioctls instead of
having multi-function ones like this.

This is technically an ABI break, but in practice it should not matter:
ifmediareq::ifm_current aligns with ifreq::ifr_media, so the things
that used this structure like our in-tree code did will continue to work.
Until this past May, the only other field that was usually set was
ifm_active, but in the absence of setting ifm_status all non-Haiku
consumers should ignore it completely.

The only consumer of this ioctl that I know of out of the tree,
wpa_supplicant, still works after these changes.

network/stack: Do not invoke SIOCGIFMEDIA but just return the already-fetched media.

This functionally disables most of the functionality of the BSD-style
SIOCGIFMEDIA, but it was never used in userland (because if it had,
it would have triggered SMAP violations in the compatibility layer.)

SIOCGIFMEDIA returns BSD-style media values, which mostly overlap
with Haiku ones but have a few differences still. These are taken care
of in the compat layer by ETHER_GET_LINK_STATE, which is where this
media value comes from, but are not by SIOCGIFMEDIA which just passes
back whatever the drivers do.

Fixes #17770, at least for ethernet drivers.

net_interface & datalink: Fix MTU handling.

The device is what actually controls the MTU, and it has its own
field for this, so having a second one just meant the MTU never
got updated after startup.

Remove the "mtu" field from the interface, use the "device->mtu" directly,
and then actually invoke device->module->set_mtu when updating.

network/stack: assume zero length ioctl requests are valid

posix ioctl calls don't provide a request length. Theorically these length checks
could be removed altogether.

* 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.

* Fixed all route locking problems, of which there were numerous

* A route will now be removed from the list in remove_route(), not in
put_route_internal(). Before, a route could easily be removed twice, causing
remove_route() to release references it did not own. This fixes bug #2706.

moved address selection logic to a new 'get_buffer_route'.

- 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.

- 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.

a bit more work towards proper locking including a fix to a refcount bug

- fixed a issue in add_interface_to_domain where the device interface's refcount was always incremented since that function was getting the device interface handle and not returning it unconditionlly
- if the ethernet device goes down, and the fd is close()ed, return B_FILE_ERROR instead of calling into the driver again


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20601 a95241bf-73f2-0310-859d-f6bbb57e9c96

started some work to properly handle device_removed() and setting interfaces down in general.

- remove all routes that use interfaces going down.
- when a device is going down, remove associated domain interfaces.
- interfaces weren't getting a properly referenced device interface, fixed.
- down call down_device_interface when deleting a interface, instead set it down and let the upcounts do its job.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20600 a95241bf-73f2-0310-859d-f6bbb57e9c96

handle all cases of SIOCSIFFLAGS in the same place


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20554 a95241bf-73f2-0310-859d-f6bbb57e9c96

don't overwrite the flags we set when the interface goes up or down, instead just update the flags in the same place.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20553 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Changed ETHER_GET_LINK_STATE ethernet driver interface, added ETHER_SET_LINK_STATE_SEM.
* 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

Support getting route information for a specific destination
using SIOCGETRT. Patch by Hugo Santos.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20494 a95241bf-73f2-0310-859d-f6bbb57e9c96

SIOCGIFCONF will now also report the size of the written buffer in ifconf.ifc_len
to cover the case the list of interfaces changed since SIOCGIFCOUNT was called.
Patch by Hugo Santos.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20491 a95241bf-73f2-0310-859d-f6bbb57e9c96

No longer crashes when deleting "certain" interfaces (couldn't reproduce the
crash in Qemu for some reason).


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20397 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Introduced a reader_thread member to the private net_device_interface.
* When shutting down an interface, we now wait until its reader thread is gone, too;
this is necessary in case the kernel unloads the networking stack before the reader
thread had a chance to exit.
* Added some debug output to net_socket in case you ask for unknown options.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19741 a95241bf-73f2-0310-859d-f6bbb57e9c96

Calmed down the networking stack a lot - since it basically works, there is no
reason to slow it down with debug output that much; this will also help investigating
some issues where you just aren't interested in most of the output.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19672 a95241bf-73f2-0310-859d-f6bbb57e9c96

We also need to put the outgoing packets into the device monitor.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19554 a95241bf-73f2-0310-859d-f6bbb57e9c96

* ARP no longer tries to resolve the target address in case of a link-level broadcast
(indicated by MSG_BCAST).
* ARP should now be able to resolve addresses with an unconfigured interface as well.
* datalink_is_local_address() now uses interfaces without an address as a fallback
in case no more specific interface could be found.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19460 a95241bf-73f2-0310-859d-f6bbb57e9c96

Minor cleanup.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19436 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Completed the previous commit and merger of the team/network/new_stack branch.
* Removed ppp_up and pppcontrol from the image for now.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@18457 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Only return the first address of the family if there was no address specified
in the request.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@40445 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Getting the device media now actually works as intended.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@39757 a95241bf-73f2-0310-859d-f6bbb57e9c96

* We now use a FreeBSD compatible ifmediareq structure for SIOCIFMEDIA, and
SIOCSIFMEDIA.
* Made sure that the two media ioctls are actually forwarded to the driver.
* Added NetworkDevice.cpp to the build.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@39389 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Made an uint32 out of net_socket::bound_to_device.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@38395 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Getting an address leaked a reference. This fixes that interfaces could not
really be deleted (a reference of them was kept in memory).


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@38179 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Spotted a few reference counting bugs that were probably responsible for
#6446, although I could not reproduce the exact problem.
* net_datalink::is_local_[link_]address() now releases a previous reference if
the _interfaceAddress arguments does not point to NULL.
* When a buffer is received from a device, it's interface_address should be NULL
already.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@38118 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Also report the address index back to the userland.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@38059 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Applied the B_SOCKET_SET_ALIAS address retrieval logic to B_SOCKET_GET_ALIAS
as well (of course, no address is created automatically here).


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@38058 a95241bf-73f2-0310-859d-f6bbb57e9c96

* datalink_control() also need to accept structures smaller than ifreq as long
as the interface name can be specified.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@38015 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Interface::_ChangeAddress() got the address check for equality wrong,
effectively rejecting any try to set an address.
* It now copies the new address as well in order to make sure that its
sa_len field is set correctly.
* Improved debug output.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@37937 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Enabled removing the interface on device removal again.
* Made the return type of remove_interface() void, as it cannot fail.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@37884 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Renamed the proprietary SIOC_* ioctls to B_SOCKET_* - no reason to pollute
global name space, and have ugly identifiers for nothing :-)
* Added a flags field to struct ifaliasreq. Added flags to mark an alias that
is currently being configured, or has been automatically configured.
Those flags aren't used yet, but they will replace IFF_CONFIGURING and
friends.
* Implemented deleting addresses only from interfaces via ifconfig.
* Added more command aliases for delete to ifconfig ("del", and "delete", for
more consistency with route).
* Fixed control_routes() to only release a reference to an address if it
actually got one before.
* If an interface address is deleted, its routes are now removed as well.
* InterfaceAddress now holds a reference to its interface as planned.
* Implemented removing interfaces. Works quite nicely.
* When downing an interface, all of its routes are now removed. When upping
it again, at least the default routes are added.
* datalink.cpp's get_interface_name_or_index() leaked a reference to the
interface found.
* SIOCAIFADDR would also leak a reference when new addresses were added.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@37872 a95241bf-73f2-0310-859d-f6bbb57e9c96

* 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.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@37870 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Work in progress of extending the AF_LINK protocol to be able to send and
receive raw packets (only without the ethernet framing).


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@37853 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Added a dedicated lock for the device monitors. This fixes a locking issue in
interface_protocol_send_data() which accessed the monitors unlocked.
* Changed SIOCCPACKETCAP to check if the device name matches the one used with
SIOCSPACKETCAP.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@37845 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Made datalink and interface protocol module functions static.
* Got rid of datalink.h.
* Only allow sending/receiving of packets through AF_LINK for root (not that
sending would be implemented yet).


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@37844 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Added new socket ioctls to strace, and the datalink debug output.
* Added a few more types to strace's network ioctls.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@37807 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Added Haiku specific socket ioctls to configure the interface aliases:
SIOC_IF_ALIAS_ADD, SIOC_IF_ALIAS_REMOVE, SIOC_IF_ALIAS_GET, SIOC_ALIAS_SET,
and SIOC_IF_ALIAS_COUNT.
* Implemented all of those new ioctls, though they are yet untested.
* Added ifreq::ifr_data, and removed the hack in the FreeBSD compat if.h
header.
* Minor cleanup.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@37806 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Reworked the complete stack to allow more than one address per network
interface - this caused quite a number of changes.
* Network interfaces, and its addresses are now reference counted (not yet
complete, though, InterfaceAddresses need to hold references to their
interface as well).
* There are two known regressions of this commit that I will fix later:
- you cannot remove interfaces anymore
- IPv4 multicast was broken anyway, but now it's disabled, too.
* Moved a device_interfaces.cpp|h out of interfaces.cpp.
* The datalink layer chain is now instantiated per domain per interface,
not just per interface anymore.
* When a buffer reaches the network layer, it has no known interface yet, ie.
the ipv4|6|whatever modules need to set this manually.
* Added more debug output, and some new debugger commands, the control option
is now printed in clear text.
* Added hash_address() function to the address modules. Added "const" to
set_to_defaults() where needed.
* Fixed net_buffer's restore header functions offset use as reported by Atis.
* Improved buffer dump output, use the domain module to print the address if
available.
* Moved net_buffer::type into the union, as it's not needed by the upper layers
anymore.
* Moved IPv6 specific code from {add|remove}_default_route() to where it
belongs, but disabled it for the time being.
* Completely discarded useless ipv4_datagram module.
* Added ping6 to the build.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@37794 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Applied next work in progress patch by Atis that takes into account most of
my comments so far. Thanks!


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@37793 a95241bf-73f2-0310-859d-f6bbb57e9c96

Work in progress commit by Atis Elsts (I'm posting his ChangeLog comments
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

* Made the stack send out interface change notifications where needed (at least
hopefully :-)).
* Improved interface change notification to include the flags that changed.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@37594 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Removed the interface fallback from the datalink module's is_local_address().
* 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.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@34466 a95241bf-73f2-0310-859d-f6bbb57e9c96

* The net_domain's lock is now a recursive lock.
* Fixed all route locking problems, of which there were numerous
({add|remove}_route(), and list_routes() did not lock at all). Added
lock assertions in functions that don't do the locking themselves.
* A route will now be removed from the list in remove_route(), not in
put_route_internal(). Before, a route could easily be removed twice, causing
remove_route() to release references it did not own. This fixes bug #2706.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@29386 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Cleanup.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@29384 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Renamed net_device_interface::rx_lock to receive_lock.
* Cleanup, improved comments, removed useless ones.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@29232 a95241bf-73f2-0310-859d-f6bbb57e9c96

* More or less completed the network notification module - it does not remove
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

* fixed receiving of IP-level broadcasts - fixing the rest of
#2065

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@27996 a95241bf-73f2-0310-859d-f6bbb57e9c96

* datalink_send_datagram() can be called with a NULL protocol which I missed
with the last commit.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@27984 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Actually implemented the SO_BINDTODEVICE socket option I added some time ago.
* 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.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@27983 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Replaced all instances of benaphores in the kernel code by mutexes.
* Removed kernel benaphores.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25690 a95241bf-73f2-0310-859d-f6bbb57e9c96

* 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.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@24170 a95241bf-73f2-0310-859d-f6bbb57e9c96

* net_buffer is a module, so it shouldn't have its initializers called
indirectly by the stack - they are now again usable separately as well.
* Minor cleanup.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22673 a95241bf-73f2-0310-859d-f6bbb57e9c96

net_device_interface: remove redundant fields


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@21222 a95241bf-73f2-0310-859d-f6bbb57e9c96

loop: no longer requires a reader thread, it delivers directly to the device's receive queue


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@21215 a95241bf-73f2-0310-859d-f6bbb57e9c96

net_interface_private: added receive queue and splited device reading from packet processing. Delivering to self no longer is executed in the sender's context, which had some problems with TCP's locking.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@21214 a95241bf-73f2-0310-859d-f6bbb57e9c96

net_buffer: preparing for better metadata management


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@21210 a95241bf-73f2-0310-859d-f6bbb57e9c96

Renamed net_device::{add|rem}_multi() to {add|remove}_multicast for consistency and clarity.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@21008 a95241bf-73f2-0310-859d-f6bbb57e9c96

added add_multi/rem_multi to net_devices. Glued the interface protocol multicast handling with net_device via add_multi/rem_multi.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20947 a95241bf-73f2-0310-859d-f6bbb57e9c96

prepared the ipv4 multicast code for full multicast support.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20945 a95241bf-73f2-0310-859d-f6bbb57e9c96

added join_multicast/leave_multicast to datalink protocols, preparing for full multicast support.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20944 a95241bf-73f2-0310-859d-f6bbb57e9c96

retrieve the incoming interface on the domain_receive_adapter(). This should fix potential issues with packets addressed to the IP broadcast address, such as in with some DHCP implementations.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20767 a95241bf-73f2-0310-859d-f6bbb57e9c96

introduced datalink's send_datagram to perform route and source address selection and dispatch the datagram to appropriate domain/protocol.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20714 a95241bf-73f2-0310-859d-f6bbb57e9c96

support RFC 3678's Protocol-Independent setsockopt()s for IPv4 multicast.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20691 a95241bf-73f2-0310-859d-f6bbb57e9c96

initial steps towards IPv4 Multicast Filter Delta API (RFC 3678)


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20690 a95241bf-73f2-0310-859d-f6bbb57e9c96

moved address selection logic to a new 'get_buffer_route'.

- 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

whenever an interface is deleted, call put_domain_datalink_protocols() so all readers are unregistered.

- Unfortunely this requires RX lock to become a recursive lock.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20621 a95241bf-73f2-0310-859d-f6bbb57e9c96

Prepared net_device_monitor to accept device removal events.

- 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

updated some locking related comments.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20613 a95241bf-73f2-0310-859d-f6bbb57e9c96

moved IFF_LINK handling to the device module (ethernet in this case). Now domain interfaces only keep specific flags such as IFF_UP and the configuration flags. IFF_LINK, IFF_BROADCAST etc are maintained exclusively by the device.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20612 a95241bf-73f2-0310-859d-f6bbb57e9c96

introduced net_device_interface level locking.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20611 a95241bf-73f2-0310-859d-f6bbb57e9c96

a bit more work towards proper locking including a fix to a refcount bug

- fixed a issue in add_interface_to_domain where the device interface's refcount was always incremented since that function was getting the device interface handle and not returning it unconditionlly
- if the ethernet device goes down, and the fd is close()ed, return B_FILE_ERROR instead of calling into the driver again

started some work to properly handle device_removed() and setting interfaces down in general.

- remove all routes that use interfaces going down.
- when a device is going down, remove associated domain interfaces.
- interfaces weren't getting a properly referenced device interface, fixed.
- down call down_device_interface when deleting a interface, instead set it down and let the upcounts do its job.

handle all cases of SIOCSIFFLAGS in the same place

don't overwrite the flags we set when the interface goes up or down, instead just update the flags in the same place.

* Changed ETHER_GET_LINK_STATE ethernet driver interface, added ETHER_SET_LINK_STATE_SEM.
* 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.

Support getting route information for a specific destination
using SIOCGETRT. Patch by Hugo Santos.

SIOCGIFCONF will now also report the size of the written buffer in ifconf.ifc_len
to cover the case the list of interfaces changed since SIOCGIFCOUNT was called.

No longer crashes when deleting "certain" interfaces (couldn't reproduce the
crash in Qemu for some reason).

* Introduced a reader_thread member to the private net_device_interface.
* When shutting down an interface, we now wait until its reader thread is gone, too;
this is necessary in case the kernel unloads the networking stack before the reader
thread had a chance to exit.
* Added some debug output to net_socket in case you ask for unknown options.

Calmed down the networking stack a lot - since it basically works, there is no
reason to slow it down with debug output that much; this will also help investigating
some issues where you just aren't interested in most of the output.

We also need to put the outgoing packets into the device monitor.

* ARP no longer tries to resolve the target address in case of a link-level broadcast
(indicated by MSG_BCAST).
* ARP should now be able to resolve addresses with an unconfigured interface as well.
* datalink_is_local_address() now uses interfaces without an address as a fallback
in case no more specific interface could be found.

* Completed the previous commit and merger of the team/network/new_stack branch.
* Removed ppp_up and pppcontrol from the image for now.
