The automatic recalculation of the maximum allowed MTU is usually triggered
by code sections which are already rtnl lock protected by callers outside
of batman-adv. But when the fragmentation setting is changed via
batman-adv's own batadv genl family, then the rtnl lock is not yet taken.
But dev_set_mtu requires that the caller holds the rtnl lock because it
uses netdevice notifiers. And this code will then fail the check for this
lock:
RTNL: assertion failed at net/core/dev.c (1953)

B.A.T.M.A.N. (better approach to mobile ad-hoc networking) is
|
|
a routing protocol for multi-hop ad-hoc mesh networks. The
|
|
networks may be wired or wireless. See
|
|
https://www.open-mesh.org/ for more information and user space
|
|
tools. This package builds version $(PKG_VERSION) of the kernel
|
|
module.
