route/addr: fix ID comparison for AF_INET and AF_INET6 addresses
For AF_INET/IPv4 addresses, the ID equality comparison must include
the net-part of the peer address:
unshare -n
ip link add T type dummy
ip link set T up
ip addr add 192.168.5.10/24 dev T
ip addr add 192.168.5.10 peer 192.168.6.1/24 dev T
ip addr add 192.168.5.10 peer 192.168.7.1/24 dev T
ip addr add 192.168.5.10 peer 192.168.7.2/24 dev T
# RTNETLINK answers: File exists
ip addr change 192.168.5.10 peer 192.168.7.2/24 dev T
ip addr show | grep 192.168.7.
# inet 192.168.5.10 peer 192.168.7.1/24 scope global T
For AF_INET6/IPv6 addresses, the prefix length of the address
is not part of the ID:
unshare -n
ip link add T type dummy
ip link set T up
ip addr add 192.168.7.10/24 dev T
ip addr add 192.168.7.10/23 dev T
ip addr add 1:2:3:4:5::1/64 dev T
ip addr add 1:2:3:4:5::1/63 dev T
# RTNETLINK answers: File exists
ip addr change 1:2:3:4:5::1/63 dev T
ip addr show | grep 1:2:3:4:5::1
# inet6 1:2:3:4:5::1/64 scope global
*sigh*
