[ Upstream commit 810c2f0 ] IPv6 addresses which are used for tunnels are stored in a hash table with reference counting. When a new GRE tunnel is configured, the driver is notified and configures it in hardware. Currently, any change in the tunnel is not applied in the driver. It means that if the remote address is changed, the driver is not aware of this change and the first address will be used. This behavior results in a warning [1] in scenarios such as the following: # ip link add name gre1 type ip6gre local 2000::3 remote 2000::fffe tos inherit ttl inherit # ip link set name gre1 type ip6gre local 2000::3 remote 2000::ffff ttl inherit # ip link delete gre1 The change of the address is not applied in the driver. Currently, the driver uses the remote address which is stored in the 'parms' of the overlay device. When the tunnel is removed, the new IPv6 address is used, the driver tries to release it, but as it is not aware of the change, this address is not configured and it warns about releasing non existing IPv6 address. Fix it by using the IPv6 address which is cached in the IPIP entry, this address is the last one that the driver used, so even in cases such the above, the first address will be released, without any warning.
