network: Always add default route after setting IP address

Previously, a default route was only added if the interface was not
set for auto configuration and it was added before the address was
configured. Currently, using DHCP for IPv4 means that the interface is
set as auto-configured (i.e. this also meant that the statically
configured default route for IPv6 wasn't even attempted to be added).
Also, adding a default route when the address hasn't been set is
questionable.

Always adding a default route (if a gateway is configured) shouldn't
cause any issues, even for auto-configuration cases, as the default
route will just be replaced once auto-configuration has completed
(which already happens for the IP address).

This change fixes network configuration where IPv6 is statically
configured and IPv4 is either also statically configured or
auto-configured.

NetServer: set B_UNCONFIGURED_ADDRESS_FAMILIES flag for IPv6 link local mask

In NetServer::_ConfigureIPv6LinkLocal, it was observed that the
IPv6 link local addresses being added by the function had invalid
masks applied, which upon investigation turned out to be
uninitialised memory.

It turns out that this call:

BNetworkAddress localLinkMask("ffff:ffff:ffff:ffff::");

...internally relies on getaddrinfo(), which only works if the OS
already has an IPv6 address. Since this is the first IPv6 address,
this will always fail. Since the error code is not checked, this
results in uninitialised memory being used as the IPv6 mask.

There are a variety of possible ways to solve this problem, but
the one presented here passes the B_UNCONFIGURED_ADDRESS_FAMILIES
flag which tells the resolver to always resolve IPv6 addresses.

net_server: Fixed overwriting wrong interface config

* When the "interfaces" file contains a configuration for a missing
device, the first interface found would be overwritten, irregardless
of its status.
* Now, _ConfigureDevices() properly honours the
"devicesAlreadyConfigured" list.
* This fixes bug #14908.

net_server: Clean up authentication handling code.

Even if we find an authentication string, make sure it's not empty before

Network: Avoid DHCP over-writing user specified DNS settings

* Adds parser to servers/net/nethost, to check current
settings in resolv.conf before updating

If user has specified DNS settings manually, DHCP derived
settings are appended to resolv.conf, rather than overwriting.

(If no user specified data is present, or in the event of
a badly damaged resolv.conf, DHCP over-writes file in same
manner as prior to this change)

Fixes #11565.

net_server: Add (more) missing devices even if one has already been found.

Fixes #6423 and helps with #14626.

In BringUpInterfaces, line 772 creates an error which only adds a missing
interface if one does not already exist (i.e., !_testInterface()). This can lead to
a missing WiFi interface if an Ethernet connection has been configured and set in
the /boot/system/settings/network/interfaces before the WiFi has had a chance to
be added to /dev/net. To properly configure a missing device, such as a WiFi
connection, and allow the user to choose amongst configured interfaces (i.e.,
add it to the list of devices in /dev/net and e.g., see WiFi as an option),
removing the 'if' statement on line 772 is necessary.

Two edge cases may arise:
1. A user may disable an interface -- don't add device
Solution: The code currently handles this. _ConfigureInterfacesFromSettings, called
at line 746, checks for interfaces in fSettings to see if they are disabled (706-711).
If so, they are disabled and not set as a missingDevice if the interface is disabled
(709). The next interface is checked... etc.

2. Devices must not be added twice (i.e., Checking for An Existing configured Network)
Solution: The code currently checks for this. On lines 716-720, a device that is found
in fSettings (missingDevice), is set to the interface which is later added to the
/dev/net within that (unnecessary?) if statement (772). The missingDevice will only
be set and added to /dev/net if an entry does not exist in the settings already (716)
(hence the identifier missingDevice).

Fixing my own mess introduced in r41274. Fix #9446.

Rework initial auto joining and add big TODOs.

* If we have a configured network, then we always try to connect to it
as soon as the interface has been brought up.
* If we don't have a configured network and are auto configuring, we
use the AutoconfigLooper to also do initial auto joins.
* Before issuing auto joins we need to wait for scan results to come
in, so we watch for corresponding messages.

For now auto joining is a one shot attempt as the infrastructure to
properly tell reasons for scans apart is not yet there.

Use the wpa_supplicant to join open networks if it is running.

We need to make sure that the wpa_supplicant knows about our intention
even when joining an open network, as it otherwise might interfere.
Since leaving a network is not synchronous and the wpa_supplicant is
already running in that case anyway, this seems easier and more
reliable.

If the wpa_supplicant is not already running we still join ourselves.

Rename _ConfigureInterfaces() to *FromSettings().

This makes it more obvious what the function does.

Don't automatically join a network if we already have a link.

The _ConfigureInterface() method is used as a backend for all
configuration tasks. That includes setting addresses manually or by
DHCP and changing flags, mtu or metric. Therefore we can't join
networks every time it is invoked. Instead we check for an existing
link first and only try to join if there is none yet.

Use a BMessenger to check for wpa_supplicant availabiltiy.

* Only launch it on join requests if it isn't yet valid anyway.
* Don't do any work on leave requests if it isn't running at all.

Implement leaving networks on the net_server side.

We always try to reach the wpa_supplicant first. If it isn't running
we check if this might have been a network we've connected directly
and then just disassociate using an MLME disassociation request.

Make a copy of the network config message and store that one.

Using the original message and storing that into the settings resulted
in a not yet fully understood deadlock. Presumably related to missing
and/or stray replies.

Close alerts with ESCAPE key.

Added SetFlags(B_CLOSE_ON_ESCAPE) or SetShortcut(index, B_ESCAPE) to BAlerts
depending if the result gets used later in the code, or if it's a one-button
BAlert.

local link connectivity.
* Duplicate Address Detection is still a TODO
* Style cleanup

* Remove the BNetworkDevice::AddPersistentNetwork() again and instead introduce
BNetworkRoster::{Count|GetNext|Add|Remove}PersistentNetwork() as it fits
better (thanks Philippe for the heads up).
* Implement the backend for these functions in the net_server and also move
conversion of the wireless_network based format into the settings based format
there.
* Implement removal of a network from the settings and make adding a new network
with the same name replace the old one instead of just adding multiple ones.
Might need to change this in the future depending on how we want to handle
multiple networks with the same name (i.e. distinguish based on BSSID or
similar).
* Fix apparent oversight that caused configured networks _not_ to be used in the
auto join attempt.
* Remove auto joining open networks. I've been bitten by that more than once now
because we happen to have an open network in the neighbourhood that I now
accidentally used to transfer quite a bit of (unencrypted) stuff before
noticing... In the future, one will instead have to explicitly join an open
network once and store that config. Note that the driver will actually still
auto-associate with open networks due to how things are set up currently.
Note also that the auto join will fire join requests whenever there's a
disassociation event, so you might see spurious join dialogs when the
wpa_supplicant actually just re-establishes the connection.
* Make join requests async again. Instead of waiting for a synchronous reply of
the wpa_supplicant we instead return success when the request has been sent.
While the API call might still be made synchronous again in the future, the
net_server should really not block on an external application. In the case of
the wpa_supplicant we would otherwise deadlock when using the new
*PersistentNetwork() API after a successful join, and in other cases we might
just unacceptably delay other calls.

* Remove (currently broken) WEP support from the net_server. It will be

In the absence of a supplicant the net_server can therefore only join open

question is actually an open network (by means of scan results or explicit
configuration) and will otherwise delegate the join request.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@28017 a95241bf-73f2-0310-859d-f6bbb57e9c96

Setting a default netmask/broadcast address is no longer needed in ifconfig
and the net_server; the network stack now does this internally since r24170;
it worked for IPv4 only, anyway.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@24171 a95241bf-73f2-0310-859d-f6bbb57e9c96

Now only removes a default route for a domain in case a new one is specified;
this fixes bug #1423, the loop interface removed the default route for the
other interface (didn't happen previously, as routes were bound to devices).


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22723 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Now uses BPathMonitor instead of the node monitor; this fixes several issues with
changes to settings files that were ignored (for example, watching "services" did
only work if "interfaces" existed).
* On services update, Services::_Update() accidently compared the pointers of the
service objects, instead of the objects themselves.
* Implemented comparison of address changes in service objects; IOW when you change
the addresses a service should bind itself to, but leave the rest of the service
unchanged, this will now be detected as well.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@21555 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Moved the network status replicant into its own application, similar to what
ProcessController and PowerStatus are doing.
* Currently polls for info only - later, the stack should support listeners for
interface related changes.
* Also works under BONE (although it doesn't make much sense to use it there).


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20655 a95241bf-73f2-0310-859d-f6bbb57e9c96

The network status icons are now correctly read from the resources (I even
forgot to add them to the server before :-)).


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20532 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Implemented loading icons from resources - doesn't seem to work yet, though.
* Fixed leaking menu items in StatusReplicant::_PrepareMenu().
* Renamed private methods to have an underscore prefix.
* Some minor style cleanup.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20531 a95241bf-73f2-0310-859d-f6bbb57e9c96

also update configured devices' status, but ignore the loopback interface.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20525 a95241bf-73f2-0310-859d-f6bbb57e9c96

tiny cleanups


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20524 a95241bf-73f2-0310-859d-f6bbb57e9c96

net_server: initial replicant version.

* Still picture-less and thus ugly.
* It provides updated information on what the net_server is doing in terms of interface configuration.
* It is also able to show simplistic address information for configured interfaces.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20523 a95241bf-73f2-0310-859d-f6bbb57e9c96

The net_server is now a BServer instead of a BApplication, IOW it doesn't rely on the
app_server being started anymore.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19816 a95241bf-73f2-0310-859d-f6bbb57e9c96

* The networking stack now removes all invalid interfaces during startup (those
where there is either no address or MAC address [ethernet only]).
* _ConfigureInterfaces() now notices if a network device that has a configuration
is gone and memorizes this configuration.
* If a new device pops up, and there is an existing configuration for a device
no longer available, that configuration will be used for the new device, allowing
you to easily move your Haiku image to a new system without losing its network
settings - it does not yet test if the IP address is already in use in the local
network, though (in which case a configuration using DHCP would be preferrable).


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19742 a95241bf-73f2-0310-859d-f6bbb57e9c96

Work-in-progress on the "services" implementation: it now reads the configuration
message, parses it, and stops/starts the services as needed - it doesn't launch
any actual servers yet, though.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19645 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Added "services" to the network settings, and refactored the settings class a bit
to be easier extendable with more classes.
* Fixed a bug in the settings that caused updated settings to be appended to the
existing ones (missing BMessage::MakeEmpty()).
* Started services system, doesn't do anything useful yet (inetd replacement).
* Fixed the bug that caused the loopback default netmask to be incorrectly chosen;
removed the temporary fix Bruno introduced before. The same bug has been in
ifconfig where I copied the code from (but wrote it there, too) :-).


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19609 a95241bf-73f2-0310-859d-f6bbb57e9c96

The loopbacl interface has a fixed netmask.



git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19607 a95241bf-73f2-0310-859d-f6bbb57e9c96

* A copy and paste bug prevented the gateway to be added (worked before the
previous commit).
* Removed the acceptance of a missing DHCP acknowledge message.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19470 a95241bf-73f2-0310-859d-f6bbb57e9c96

* An interface can now also be configured to be "auto config" (which means DHCP for now).
* Some minor cleanup in the DHCP client.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19465 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Work-in-progress of DHCP - the interface should now be correctly configured.
* Lease times are currently ignored, though.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19462 a95241bf-73f2-0310-859d-f6bbb57e9c96

The beginnings of automatic configuration of network devices using DHCP; this is
currently only triggered when there is no configuration file - it can't be configured
this way yet.
All DHCP currently does is to send a UDP broadcast DHCP discover message. More to come.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19437 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Implemented node monitoring: if you change the interfaces settings file, the
networking stack is reconfigured automatically.
* The previous default route is now removed before installing a new one.
* "gateway" was missing in the driver settings to BMessage conversion template,
and thus, it was only set to a default value in case there was no settings
file.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19086 a95241bf-73f2-0310-859d-f6bbb57e9c96

Now also supports setting a gateway through the configuration.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19085 a95241bf-73f2-0310-859d-f6bbb57e9c96

Now checks if a valid configuration was found, and if that's not the case, it
will automatically configure the stack - without DHCP for now.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19084 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Moved settings stuff into its own file.
* Minor cleanup.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19083 a95241bf-73f2-0310-859d-f6bbb57e9c96

Started writing the new networking server. Right now, it'll configure the
networking stack according to some settings file. Doesn't do anything beyond
that yet, though.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19082 a95241bf-73f2-0310-859d-f6bbb57e9c96

Bye, bye, poor net_server. :)


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@14352 a95241bf-73f2-0310-859d-f6bbb57e9c96

- updated email-address
- removed profiles, ppp_up, and some TODOs
- simplified KPPPReportManager and reports API, KPPPInterface::Up()+Down(), and PPPInterfaceListener (also removed some features from the last one)
- KPPPInterface now sends the last PPP_CONNECTION_REPORT message to every newly registered report receiver
- added net_server to the build, but removed old net_server testing-stuff

all changes are completely untested


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@14338 a95241bf-73f2-0310-859d-f6bbb57e9c96

Changed license headers. Consider net_server as dead.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10118 a95241bf-73f2-0310-859d-f6bbb57e9c96

Nothing special. Just bringing the cvs version up-to-date with my private version.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7206 a95241bf-73f2-0310-859d-f6bbb57e9c96

Initial checkin of skeleton net_server.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7136 a95241bf-73f2-0310-859d-f6bbb57e9c96

net_server: fixed configuring disabled interfaces.

* BNetworkSettings now set unspecified addresses to their empty family
specific addresses, instead of using AF_UNSPEC.
* This allows the net_server to set those addresses on the address
specific stack interface.

net_server: Clients can now check if a service is running.

* Using the new kMsgIsServiceRunning command.

BNetworkSettings: added some convenience methods.

* From InterfaceAddressView: FindFirstAddress(), and IsAutoConfigure().
* Removed some debug leftovers in InterfaceAddressView, too.

Moved more functionality from net_server to NetworkSettings.

* Added (still incomplete) helper classes for the settings messages.
* The net_server now uses these classes for its interfaces, and services.
* Renamed service_address to service_connection, as that better matches
what it is used for.

Moved net_server's settings to libbnetapi.

* As experimental API class BNetworkSettings.
* Added add/remove methods for interfaces, and services, too.
* Moved the conversion of the wireless networks into the settings class,
too, so that it only gives out converted ones (but accepts both
variants).

Revert "Move getifaddrs to libnetwork again."

This reverts commit 31ea76548a64b232ed10cb444bf84ca1f7e40b0f.

Adrien, please try again without clobbering the otherwise nice
BNetworkInterface API!

Conflicts:
src/kits/network/getifaddrs.cpp

Move getifaddrs to libnetwork again.

* BNetworkInterfaceAddress is moved to libnetwork. It is modified to not
use BNetworkAddress (which is in libbnetapi) and instead use sockaddr
and sockaddr_storage directly. All callers are adjusted to this.
* Some support code is shared between BNetworkInterface and
BNetworkInterfaceAddress, move it to libnetwork but in the BPrivate
namespace.

include strings.h where appriopriate...

instead or additionally to string.h, in preparation for functions move.
* moves str[n]casecmp() functions and others to strings.h.
* strings.h doesn't include string.h anymore.
* this solves #10949

Remove /boot/common for good

* Remove support for the "common" installation location from packagefs,
package kit, package daemon, package managers.
* Rename the B_COMMON_*_DIRECTORY constants referring to writable
directories to B_SYSTEM_*_DIRECTORY.
* Remove/adjust the use of various B_COMMON_*_DIRECTORY constants.
I'm sure some occurrence still remain. They can be adjusted when the
remaining B_COMMON_*_DIRECTORY constants are removed.

net_server: Support joining networks by address.

* Until now, only the SSID name was being used to select a certain network.
* Now, you can also specify an address.
* Unfortunately, I could not test these changes, but they are part of ticket
#10001.

servers/net: Make DHCP client more RFC 2131 compliant

* The client should enter state REBINDING only when RENEWING times
out.
* When in RENEWING or REBINDING state do not give up retrying
unless the lease expires.
* Fix bug sending 2^n DHCP requests at n-th lease renewal.
* Use timeout values and renewal/rebinding times suggested by the
RFC.
* Use different XIDs in subsequent transactions.

Use incorrect use of BPathMonitor in input/midi/net server

The B_ENTRY_* constants aren't valid watch flags.

NetServer: Disable IPv6 link local address (for now)

* After lots of testing and playing, our v6 stack
just isn't ready for this level of prime time as
we lack IPv6 address scope flags.
* Fixes regression in #9594

net_server: 0xff is out of the bound of char, use uint8 instead

* found by GCC 4.7.3

Fixing my own mess introduced in r41274. Fix #9446.

Rework initial auto joining and add big TODOs.

* If we have a configured network, then we always try to connect to it
as soon as the interface has been brought up.
* If we don't have a configured network and are auto configuring, we
use the AutoconfigLooper to also do initial auto joins.
* Before issuing auto joins we need to wait for scan results to come
in, so we watch for corresponding messages.

For now auto joining is a one shot attempt as the infrastructure to
properly tell reasons for scans apart is not yet there.

Use the wpa_supplicant to join open networks if it is running.

We need to make sure that the wpa_supplicant knows about our intention
even when joining an open network, as it otherwise might interfere.
Since leaving a network is not synchronous and the wpa_supplicant is
already running in that case anyway, this seems easier and more
reliable.

If the wpa_supplicant is not already running we still join ourselves.

Rename _ConfigureInterfaces() to *FromSettings().

This makes it more obvious what the function does.

Don't automatically join a network if we already have a link.

The _ConfigureInterface() method is used as a backend for all
configuration tasks. That includes setting addresses manually or by
DHCP and changing flags, mtu or metric. Therefore we can't join
networks every time it is invoked. Instead we check for an existing
link first and only try to join if there is none yet.

Use a BMessenger to check for wpa_supplicant availabiltiy.

* Only launch it on join requests if it isn't yet valid anyway.
* Don't do any work on leave requests if it isn't running at all.

Implement leaving networks on the net_server side.

We always try to reach the wpa_supplicant first. If it isn't running
we check if this might have been a network we've connected directly
and then just disassociate using an MLME disassociation request.

Make a copy of the network config message and store that one.

Using the original message and storing that into the settings resulted
in a not yet fully understood deadlock. Presumably related to missing
and/or stray replies.

Close alerts with ESCAPE key.

Added SetFlags(B_CLOSE_ON_ESCAPE) or SetShortcut(index, B_ESCAPE) to BAlerts
depending if the result gets used later in the code, or if it's a one-button
BAlert.

net server: Remove un-needed braces. Look for network stack vs ipv4

net server: IPv6, there is no place like ::1

* Add new function to check for protocol support
* If IPv6 support is present assign ::1 to loopback
* ping6 ::1 functions 100%
* Still some route strangeness with link local addresses

net server: IPv6, look at nic flags vs name for loop

net server: IPv6 local link, Use BNetworkAddress tools for mac

* Stop using sscanf
* Start using BNetworkAddress LinkLevelAddress and friends
* Thanks Axel!

NetServer: Prevent duplicate v6 link local addresses

* Check to ensure the address doesn't already exist on card
* In the future we will want to check interface address flags
for any local scoped addresses on a card.

NetServer: Add IPv6 link local address to each nic on boot

* Remove old ioctl code, cleanup AutoLooper.
* Move link local code into NetServer
AutoLooper should only be used for things that
count as "auto-configuration" such as DHCP, router
advertisements, and DHCPv6
* Properly form IPv6 link local address from MAC address
* I think some IPv6 routes are needed still for proper
local link connectivity.
* Duplicate Address Detection is still a TODO
* Style cleanup

* Remove the BNetworkDevice::AddPersistentNetwork() again and instead introduce
BNetworkRoster::{Count|GetNext|Add|Remove}PersistentNetwork() as it fits
better (thanks Philippe for the heads up).
* Implement the backend for these functions in the net_server and also move
conversion of the wireless_network based format into the settings based format
there.
* Implement removal of a network from the settings and make adding a new network
with the same name replace the old one instead of just adding multiple ones.
Might need to change this in the future depending on how we want to handle
multiple networks with the same name (i.e. distinguish based on BSSID or
similar).
* Fix apparent oversight that caused configured networks _not_ to be used in the
auto join attempt.
* Remove auto joining open networks. I've been bitten by that more than once now
because we happen to have an open network in the neighbourhood that I now
accidentally used to transfer quite a bit of (unencrypted) stuff before
noticing... In the future, one will instead have to explicitly join an open
network once and store that config. Note that the driver will actually still
auto-associate with open networks due to how things are set up currently.
Note also that the auto join will fire join requests whenever there's a
disassociation event, so you might see spurious join dialogs when the
wpa_supplicant actually just re-establishes the connection.
* Make join requests async again. Instead of waiting for a synchronous reply of
the wpa_supplicant we instead return success when the request has been sent.
While the API call might still be made synchronous again in the future, the
net_server should really not block on an external application. In the case of
the wpa_supplicant we would otherwise deadlock when using the new
*PersistentNetwork() API after a successful join, and in other cases we might
just unacceptably delay other calls.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@42816 a95241bf-73f2-0310-859d-f6bbb57e9c96

Add message handling for adding persistent network configurations (as in
wireless_network).


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@42806 a95241bf-73f2-0310-859d-f6bbb57e9c96

Small cleanup.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@42799 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Fill out the wireless network join request as detailed as possible, but don't
fail when encountering missing information (like the password). This gives the
supplicant an opportunity to ask for the required information as needed.
* Remove (currently broken) WEP support from the net_server. It will be
delegated to the supplicant as well, as that one already handles all the
key/password conversion.

In the absence of a supplicant the net_server can therefore only join open
networks now. It will also only attempt that if it is sure that the network in
question is actually an open network (by means of scan results or explicit
configuration) and will otherwise delegate the join request.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@42774 a95241bf-73f2-0310-859d-f6bbb57e9c96

Patch by Atis Elsts from GSoC 2010 that was overlooked.
- Adds IPv6 fragmentation support and some partial work to enable configuration of IPv6 in net_server. Not currently in the build.



git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@41291 a95241bf-73f2-0310-859d-f6bbb57e9c96

Implemented INIT-REBOOT DHCP state: as required per DHCP specs,
we now request the last address we got from DHCP server, and only on failure
we fallback on the whole INIT state (discover, collect offer, etc).
This should fix people losing their IP address at each renewal, or far worse,
after the link goes up again.
Closed #7346.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@41285 a95241bf-73f2-0310-859d-f6bbb57e9c96

Avoid deadlock.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@41278 a95241bf-73f2-0310-859d-f6bbb57e9c96

Quit AutoconfigLooper when switching to static configuration.
Before, DHCP will still run after a link down & up event, which could
leads to break the user-defined static configuration.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@41277 a95241bf-73f2-0310-859d-f6bbb57e9c96

Check node monitoring messages to handle them only when it make sense.
Before, the "interfaces" settings file creation/removal notification was
leading to a attempt to configure/remove an interface named
"/boot/common/settings/network/interfaces"!
Could help fixing issue #7475.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@41274 a95241bf-73f2-0310-859d-f6bbb57e9c96

* The net_server now tries to join the network via wpa_supplicant, if available.
* Add some output when automatically joining a network.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@39851 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Turned on automatically joining a network even if none has been configured.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@39836 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Added some authentication config stuff to the settings. Now you can override
the detected defaults with your own values.
* Implemented joining open and WEP networks - this is pretty much untested,
though.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@39794 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Work in progress of WLAN support in the net_server.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@39783 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Don't overwrite the family if it is being passed as int32.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@39600 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Now uses the new network API instead of directly using socket ioctls.
This makes the code much cleaner and simpler.
* Completely untested, though (will do that next).


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@39595 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

* On Haiku, ifreq::ifr_name always includes the trailing null byte. Adjusted
userland code to take this into account (the kernel would just cut off the
name).
* This closes ticket #6280.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@37689 a95241bf-73f2-0310-859d-f6bbb57e9c96

Add interface disabling support.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@37091 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Style cleanup.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@36137 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Applied patch by Vegard that moves the resolver configuration to where it

* This closes ticket #5636.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@36135 a95241bf-73f2-0310-859d-f6bbb57e9c96

NetServer: Clear the IFF_AUTO_CONFIGURED as needed. It was cleared at reboot, but not when the config file was updated.

Fixing ticket #3912.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@35410 a95241bf-73f2-0310-859d-f6bbb57e9c96

Patch by Humdinger:
Switched strings to sentence case in servers and kits. This is the
case-servers+kits.diff applied from #5169. Couldn't spot any possibly
problematic changes.
Thanks a lot!


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@35044 a95241bf-73f2-0310-859d-f6bbb57e9c96

Some simplifications (thanks Axel):
* Don't watch for moved entries
* Ask the network stack to delete the named interface


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@34648 a95241bf-73f2-0310-859d-f6bbb57e9c96

* free buffer on ioctl failures
* monitors /dev/net for added or removed devices and handles events
by configuring or unconfiguring interfaces. When plugged a usb
network device, it now appears correcly.

* Made defines out of the kNetServerSignature and kMsgConfigureInterface
constants - they are used in other apps as well, and defining them as
"static const" causes undefined warnings in other source files. This also
fixes the build.
* Changed "interfaces::auto config" to auto_config, as that's more convenient
to use in the settings files.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@32321 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Added "stand_alone" setting to the services - this way you can use the
net_server to launch services that work like a daemon theirselves (like sshd).
A service like this is also killed (via SIGTERM) when the netserver stops the
service (with sshd, you have to pass the '-D' option to make this work).
* If a boolean is given without value, it now defaults to true.
* The "launch" argument now gets its arguments properly parsed, and added, too.
* Services::_Update() did accidently set fUpdate on the wrong service, causing
services that were not changed to be stopped.
* More helpful output.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@32319 a95241bf-73f2-0310-859d-f6bbb57e9c96

* The auto-config looper now correctly sets the IFF_CONFIGURING flag - it
cannot be set in the AF_LINK level.
* It now also checks for this flag, so that the fallback configuration won't
overwrite a manually configured interface anymore.
* When an interface is configured, the IFF_CONFIGURING flag is now cleared as
it should.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@29230 a95241bf-73f2-0310-859d-f6bbb57e9c96

* The net_server now accepts messages from the outside that want to configure
an interface (I don't remember why I didn't want this earlier, but well).
* ifconfig now has an auto-config option that will trigger DHCP.
* Also, it will now remove the IFF_AUTO_CONFIGURED and IFF_CONFIGURING flags
if an address is specified (any on-going auto-configuration should check for
these and abort if they aren't there anymore).


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@28831 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Pulled an AutoconfigClient class out of DHCPClient - all clients are supposed
to inherit from that one (there is still just a single client, though, this
just simplifies having a generic mechanism to register and use auto-config
clients).
* AutoconfigLooper now listens to link changes, and will reconfigure the
interface if a new link is there - this even seems to work in emulation, will
test on real hardware next.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@28827 a95241bf-73f2-0310-859d-f6bbb57e9c96

* DHCP now actually uses the new SO_BINDTODEVICE socket option to make sure
the request is sent only on the device it should.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@28017 a95241bf-73f2-0310-859d-f6bbb57e9c96

Setting a default netmask/broadcast address is no longer needed in ifconfig
and the net_server; the network stack now does this internally since r24170;
it worked for IPv4 only, anyway.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@24171 a95241bf-73f2-0310-859d-f6bbb57e9c96

Now only removes a default route for a domain in case a new one is specified;
this fixes bug #1423, the loop interface removed the default route for the
other interface (didn't happen previously, as routes were bound to devices).


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22723 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Now uses BPathMonitor instead of the node monitor; this fixes several issues with
changes to settings files that were ignored (for example, watching "services" did
only work if "interfaces" existed).
* On services update, Services::_Update() accidently compared the pointers of the
service objects, instead of the objects themselves.
* Implemented comparison of address changes in service objects; IOW when you change
the addresses a service should bind itself to, but leave the rest of the service
unchanged, this will now be detected as well.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@21555 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Moved the network status replicant into its own application, similar to what
ProcessController and PowerStatus are doing.
* Currently polls for info only - later, the stack should support listeners for
interface related changes.
* Also works under BONE (although it doesn't make much sense to use it there).


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20655 a95241bf-73f2-0310-859d-f6bbb57e9c96

The network status icons are now correctly read from the resources (I even
forgot to add them to the server before :-)).


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20532 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Implemented loading icons from resources - doesn't seem to work yet, though.
* Fixed leaking menu items in StatusReplicant::_PrepareMenu().
* Renamed private methods to have an underscore prefix.
* Some minor style cleanup.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20531 a95241bf-73f2-0310-859d-f6bbb57e9c96

also update configured devices' status, but ignore the loopback interface.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20525 a95241bf-73f2-0310-859d-f6bbb57e9c96

tiny cleanups


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20524 a95241bf-73f2-0310-859d-f6bbb57e9c96

net_server: initial replicant version.

* Still picture-less and thus ugly.
* It provides updated information on what the net_server is doing in terms of interface configuration.
* It is also able to show simplistic address information for configured interfaces.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20523 a95241bf-73f2-0310-859d-f6bbb57e9c96

The net_server is now a BServer instead of a BApplication, IOW it doesn't rely on the
app_server being started anymore.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19816 a95241bf-73f2-0310-859d-f6bbb57e9c96

* The networking stack now removes all invalid interfaces during startup (those
where there is either no address or MAC address [ethernet only]).
* _ConfigureInterfaces() now notices if a network device that has a configuration
is gone and memorizes this configuration.
* If a new device pops up, and there is an existing configuration for a device
no longer available, that configuration will be used for the new device, allowing
you to easily move your Haiku image to a new system without losing its network
settings - it does not yet test if the IP address is already in use in the local
network, though (in which case a configuration using DHCP would be preferrable).


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19742 a95241bf-73f2-0310-859d-f6bbb57e9c96

Work-in-progress on the "services" implementation: it now reads the configuration
message, parses it, and stops/starts the services as needed - it doesn't launch
any actual servers yet, though.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19645 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Added "services" to the network settings, and refactored the settings class a bit
to be easier extendable with more classes.
* Fixed a bug in the settings that caused updated settings to be appended to the
existing ones (missing BMessage::MakeEmpty()).
* Started services system, doesn't do anything useful yet (inetd replacement).
* Fixed the bug that caused the loopback default netmask to be incorrectly chosen;
removed the temporary fix Bruno introduced before. The same bug has been in
ifconfig where I copied the code from (but wrote it there, too) :-).


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19609 a95241bf-73f2-0310-859d-f6bbb57e9c96

The loopbacl interface has a fixed netmask.



git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19607 a95241bf-73f2-0310-859d-f6bbb57e9c96

* A copy and paste bug prevented the gateway to be added (worked before the
previous commit).
* Removed the acceptance of a missing DHCP acknowledge message.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19470 a95241bf-73f2-0310-859d-f6bbb57e9c96

* An interface can now also be configured to be "auto config" (which means DHCP for now).
* Some minor cleanup in the DHCP client.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19465 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Work-in-progress of DHCP - the interface should now be correctly configured.
* Lease times are currently ignored, though.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19462 a95241bf-73f2-0310-859d-f6bbb57e9c96

The beginnings of automatic configuration of network devices using DHCP; this is
currently only triggered when there is no configuration file - it can't be configured
this way yet.
All DHCP currently does is to send a UDP broadcast DHCP discover message. More to come.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19437 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Implemented node monitoring: if you change the interfaces settings file, the
networking stack is reconfigured automatically.
* The previous default route is now removed before installing a new one.
* "gateway" was missing in the driver settings to BMessage conversion template,
and thus, it was only set to a default value in case there was no settings
file.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19086 a95241bf-73f2-0310-859d-f6bbb57e9c96

Now also supports setting a gateway through the configuration.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19085 a95241bf-73f2-0310-859d-f6bbb57e9c96

Now checks if a valid configuration was found, and if that's not the case, it
will automatically configure the stack - without DHCP for now.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19084 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Moved settings stuff into its own file.
* Minor cleanup.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19083 a95241bf-73f2-0310-859d-f6bbb57e9c96

Started writing the new networking server. Right now, it'll configure the
networking stack according to some settings file. Doesn't do anything beyond
that yet, though.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19082 a95241bf-73f2-0310-859d-f6bbb57e9c96

Bye, bye, poor net_server. :)


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@14352 a95241bf-73f2-0310-859d-f6bbb57e9c96

- updated email-address
- removed profiles, ppp_up, and some TODOs
- simplified KPPPReportManager and reports API, KPPPInterface::Up()+Down(), and PPPInterfaceListener (also removed some features from the last one)
- KPPPInterface now sends the last PPP_CONNECTION_REPORT message to every newly registered report receiver
- added net_server to the build, but removed old net_server testing-stuff

all changes are completely untested


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@14338 a95241bf-73f2-0310-859d-f6bbb57e9c96

Changed license headers. Consider net_server as dead.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10118 a95241bf-73f2-0310-859d-f6bbb57e9c96

Nothing special. Just bringing the cvs version up-to-date with my private version.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7206 a95241bf-73f2-0310-859d-f6bbb57e9c96

Initial checkin of skeleton net_server.
