Subject: [PATCH v2 0/4] Device blacklisting
Message-ID: <[email protected]>
Hi,
Version 2 contains only commit message fixes, so no changes to the
code. I'm still waiting for a particular person/project to test this,
but if you have noticed a problem with interface blacklisting, go
ahead and test. If it works properly I won't wait forever for that
particular person :-)
Cheers,
Patrik

Message-ID: <[email protected]>
detect.c only deals with devices detected by information from kernel
RTNL updates. Simplify code dependencies by adding the same functionality
into device.c instead.

Subject: [PATCH v2 3/4] rtnl: Send also interface name in the RTNL
callback
Message-ID: <[email protected]>
Since the interface name is known, send it to the RTNL callbacks.
Right now triggering of RTNL information on rtnl_trigger() is sending
the interface name as NULL since this information is not stored.
For the built-in code RTNL callbacks are registered during
initialization when no devices or networks have yet been created
so this will not be a problem.

Subject: [PATCH v2 4/4] device: Check interface blacklist on receiving
RTNL newlink
Message-ID: <[email protected]>
Check interface blacklist status when RTNL newlink messages are received.
If the interface already exists, i.e. the interface was renamed with
the new name blacklisted, remove the interface. Notice that blacklisting
is applied only on wifi, ethernet and gadget technologies as these are
the ones detected via RTNL messages. Bluetooth and cellular networks are
controlled via Bluez and oFono daemons from ConnMan, with ConnMan having
better control of which networks and therefore interfaces are meant to be
used.

Subject: [PATCH v2 2/4] rtnl: Always set service and device type
Message-ID: <[email protected]>
Always set a service and device type for a newly created RTNL
interface. With this change blacklisting will take place only
once, on device creation in connman_device_create_from_index().
Once past blacklisting in connman_device_create_from_index(),
the next device creation criteria is its device type. If an
unknown type were to be returned as a result of the previously
existing read_uevent() blacklisting code, the device would not
be created either. As all RTNL devices and their types are
remembered starting with reception of the first RTNL newlink,
__connman_rtnl_get_device_type() must always return the proper
device type in order to create the device.

In our environment where we only need to ignore some network
interfaces, we don't see any regression. Please, take into account we
don't modify interface name at runtime thus I did not test what this
path set is really fixing. I just would like to add that there is
something about GLib is now "complaining" at the initialization:
