batman-adv: no need to check return value of debugfs_create functions

2019-06-27T17:25:04+00:00

When calling debugfs functions, there is no need to ever check the
return value.  The function can work or not, but the code logic should
never do something different based on this.

Because we don't care if debugfs works or not, this trickles back a bit
so we can clean things up by making some functions return void instead
of an error value that is never going to fail.

batman-adv: Add includes for deprecation warning

2018-11-12T09:41:50+00:00

The commit 00caf6a2b318 ("batman-adv: Mark debugfs functionality as
deprecated") introduced various messages to inform the user about the
deprecation of the debugfs based functionality. The messages also include
the context/task in which this problem was observed.

The datastructures and functions to access this information require special
headers. These should be included directly instead of depending on a more
complex and fragile include chain.

batman-adv: Mark debugfs functionality as deprecated

2018-09-14T08:50:26+00:00

CONFIG_BATMAN_ADV_DEBUGFS is disabled by default because debugfs is not
supported for batman-adv interfaces in any non-default netns. Any remaining
users of this interface should still be informed about the deprecation and
the generic netlink alternative.

batman-adv: Fix debugfs path for renamed softif

2018-06-23T08:29:33+00:00

batman-adv is creating special debugfs directories in the init
net_namespace for each created soft-interface (batadv net_device). But it
is possible to rename a net_device to a completely different name then the
original one.

It can therefore happen that a user registers a new batadv net_device with
the name "bat0". batman-adv is then also adding a new directory under
$debugfs/batman-adv/ with the name "wlan0".

The user then decides to rename this device to "bat1" and registers a
different batadv device with the name "bat0". batman-adv will then try to
create a directory with the name "bat0" under $debugfs/batman-adv/ again.
But there already exists one with this name under this path and thus this
fails. batman-adv will detect a problem and rollback the registering of
this device.

batman-adv must therefore take care of renaming the debugfs directories for
soft-interfaces whenever it detects such a net_device rename.
