Hi! I could not see any locking being done with "struct net_device" at all even tough there are many read+write accesses to non-atomic variables. For example:
Changing mac addresses: user space netlink socket call to set IFLA_ADDRESS http://lxr.linux.no/linux+v3.1.6/net/core/rtnetlink.c#L1521 http://lxr.linux.no/linux+v3.1.6/net/core/rtnetlink.c#L1322 call to device, e.g. http://lxr.linux.no/linux+v3.1.6/drivers/net/e100.c#L2195 Sending an arp response: http://lxr.linux.no/linux+v3.1.6/net/ipv4/arp.c#L859 Any ideas/pointers? -Michi -- programing a layer 3+4 network protocol for mesh networks see http://michaelblizek.twilightparadox.com _______________________________________________ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
