UBSAN: Undefined behaviour in net/netfilter/ipset/ip_set_hash_gen.h:125:6
batman_adv: batadv0: The MTU of interface veth3 is too small (1500) to handle the transport of batman-adv packets. Packets going over this interface will be fragmented on layer2 which could impact the performance. Setting the MTU to 1560 would solve the problem.
shift exponent 32 is too large for 32-bit type 'unsigned int'
