batman-adv: Add includes for deprecation warning

2018-11-12T09:41:50Z

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. Signed-off-by: Sven Eckelmann Signed-off-by: Simon Wunderlich

batman-adv: Mark debugfs functionality as deprecated

2018-09-14T08:50:26Z

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. Signed-off-by: Sven Eckelmann Signed-off-by: Simon Wunderlich

batman-adv: Fix debugfs path for renamed softif

2018-06-23T08:29:33Z

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.

batman-adv: Fix debugfs path for renamed hardif

2018-06-23T08:29:33Z

batman-adv is creating special debugfs directories in the init net_namespace for each valid hard-interface (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 net_device which gets the name "wlan0" assigned by default. batman-adv is also adding a new directory under $debugfs/batman-adv/ with the name "wlan0". The user then decides to rename this device to "wl_pri" and registers a different device. The kernel may now decide to use the name "wlan0" again for this new device. batman-adv will detect it as a valid net_device and tries to create a directory with the name "wlan0" under $debugfs/batman-adv/. 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 hard-interfaces whenever it detects such a net_device rename.

batman-adv: Add kernel-doc to externally visible functions

2017-12-15T16:29:24Z

According to the kernel-doc documentation, externally visible functions should be documented. This refers to all all non-static function which can (and will) be used by functions in other sources files. Signed-off-by: Sven Eckelmann Signed-off-by: Simon Wunderlich

batman-adv: Use parentheses in function kernel-doc

2017-12-15T16:29:20Z

The documentation describing kernel-doc comments for functions ("How to format kernel-doc comments") uses parentheses at the end of the function name. Using this format allows to use a consistent style when adding documentation to a function and when referencing this function in a different kernel-doc section.
