Hi Adrian,
I am thinking of creating a new bug in Trac to track this
issue of maintaining (interface, address family) state and submit my patch
related to it . Does it sound good to you?
Thanks,
Sayan Chaudhuri

So, this line of code that stores only the configured device name and
not a pair of configured(device name, address) is a blocker for the review
request (https://review.haiku-os.org/c/haiku/+/7259?tab=comments) .
I am thinking of a solution like this
1. inside function NetServer::_ConfigureInterfacesFromSettings, we have
the below two lines
if (_ConfigureInterface(interface) == B_OK)
devicesSet.Add(device);
instead of this , may be we can have devicesSet type as a map of
(BNetworkDevice,BNetworkInterfaceAddress) and then add the configured
device and address family pairs from the message
variable "interface" to devicesSet. I do not know / could not find if
any map class already exists in Haiku.
The NetServer.cpp code that you linked already has fDeviceMap that is
implemented using C++ standard std::map.
I think you can also use an std::map from standard C++ for your needs here.
2. Similarly inside NetServer::_ConfigureDevices, instead of checking
only for the device
if (entry.GetName(name) != B_OK
|| entry.GetPath(&path) != B_OK
|| entry.GetStat(&stat) != B_OK
|| devicesAlreadyConfigured.HasString(path.Path()))
we can check for combination of device and address family being present
. if the pair is not present . then move on to auto_configure them0. Would
like to have community feedback on this approach .
The "devicesAlreadyConfigured" variable is currently a simple BStringList
(a list of strings containing just device names).
This will need some changes, both in the _ConfigureDevices function but
also in _ConfigureInterfacesFromSettings and _BringUpInterfaces, to make it
more explicit what is configured and what isn't. Maybe introduce a new
class to track the state of each device and each address family inside that
device, instead of the currently used string list.
I hope this helps,
