This patch provides an ipv6 proc file named "disable_gen_linklocal_addr", its absolute path is as follows: "/proc/sys/net/ipv6/conf/<iface>/disable_gen_linklocal_addr". When the "disable_gen_linklocal_addr" value of a device is 1, it means that this device does not need the Linux kernel to automatically generate the ipv6 link-local address no matter which IN6_ADDR_GEN_MODE is used.doesn't this duplicate addr_gen_mode == 1 == IN6_ADDR_GEN_MODE_NONE?Hi David, Thanks for your review. This patch is different with IN6_ADDR_GEN_MODE_NONE. When the addr_gen_mode == IN6_ADDR_GEN_MODE_NONE, the Linux kernel doesn't automatically generate the ipv6 link-local address.

After this patch, when the "disable_gen_linklocal_addr" value of a device is 1, no matter in which addr_gen_mode, the Linux kernel will not automatically generate an ipv6 link-local for this device.
those 2 sentences are saying the same thing to me. for your use case, why is setting addr_gen_mode == 1 for the device not sufficient? _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
