The following commit has been merged in the master branch: commit ec2f877856e0af3889940e00b160f7f20f8d774f Author: Pankaj Bharadiya <pankaj.laxminarayan.bharadiya(a)intel.com> Date: Tue Sep 24 16:28:36 2019 +0530 treewide: Use sizeof_member() macro Replace all the occurrences of FIELD_SIZEOF() and sizeof_field() with sizeof_member() except at places where these are defined. Later patches will remove the unused definitions.

The following commit has been merged in the master branch: commit a8d23cbbf6c9f515ed678204ad2962be7c336344 Author: Sven Eckelmann <sven(a)narfation.org> Date: Thu Oct 3 17:02:01 2019 +0200 batman-adv: Avoid free/alloc race when handling OGM2 buffer A B.A.T.M.A.N. V virtual interface has an OGM2 packet buffer which is initialized using data from the 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 data is sent out or the functions modifying the OGM2 buffer try to access already freed memory regions.

The following commit has been merged in the master branch: commit 40e220b4218bb3d278e5e8cc04ccdfd1c7ff8307 Author: Sven Eckelmann <sven(a)narfation.org> Date: Thu Oct 3 17:02:01 2019 +0200 batman-adv: Avoid free/alloc race when handling OGM buffer 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.
