batman-adv: Avoid free/alloc race when handling OGM buffer

2019-10-13T19:00:07Z

Each slave interface of an B.A.T.M.A.N. IV virtual interface has an OGM packet buffer which is initialized using data from netdevice notifier and other rtnetlink related hooks. It is sent regularly via various slave interfaces of the batadv virtual interface and in this process also modified (realloced) to integrate additional state information via TVLV containers. It must be avoided that the worker item is executed without a common lock with the netdevice notifier/rtnetlink helpers. Otherwise it can either happen that half modified/freed data is sent out or functions modifying the OGM buffer try to access already freed memory regions.

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

2019-06-27T17:25:04Z

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: Fix duplicated OGMs on NETDEV_UP

2019-06-02T11:33:48Z

The state of slave interfaces are handled differently depending on whether the interface is up or not. All active interfaces (IFF_UP) will transmit OGMs. But for B.A.T.M.A.N. IV, also non-active interfaces are scheduling (low TTL) OGMs on active interfaces. The code which setups and schedules the OGMs must therefore already be called when the interfaces gets added as slave interface and the transmit function must then check whether it has to send out the OGM or not on the specific slave interface. But the commit f0d97253fb5f ("batman-adv: remove ogm_emit and ogm_schedule API calls") moved the setup code from the enable function to the activate function. The latter is called either when the added slave was already up when batadv_hardif_enable_interface processed the new interface or when a NETDEV_UP event was received for this slave interfac. As result, each NETDEV_UP would schedule a new OGM worker for the interface and thus OGMs would be send a lot more than expected.

batman-adv: Avoid WARN on net_device without parent in netns

2018-12-30T12:34:12Z

It is not allowed to use WARN* helpers on potential incorrect input from the user or transient problems because systems configured as panic_on_warn will reboot due to such a problem. A NULL return value of __dev_get_by_index can be caused by various problems which can either be related to the system configuration or problems (incorrectly returned network namespaces) in other (virtual) net_device drivers. batman-adv should not cause a (harmful) WARN in this situation and instead only report it via a simple message.
