Subject: [PATCH] Fix IPv6 address deletion
Hi,
If you add more than one IPv6 address belonging to the same prefix and
delete the address that was last added, routing table entry for that
prefix is also deleted.
Tested on 2.6.14.4
To reproduce:
ip addr add 3ffe::1/64 dev eth0
ip addr add 3ffe::2/64 dev eth0
/* wait DAD */
sleep 1
ip addr del 3ffe::2/64 dev eth0
ip -6 route
(route to 3ffe::/64 should be gone)
In ipv6_del_addr(), if ifa == ifp, we set ifa->if_next to NULL, and
later
assign ifap = &ifa->if_next, effectively terminating the for-loop.
This prevents us from checking if there are other addresses using the
same
prefix that are valid, and thus resulting in deletion of the prefix.
This applies only if the first entry in idev->addr_list is the address
to
be deleted.
