If an Echo Request is detected, the IPv6 source address of the Echo Response message is determined by calling ip6_select_source_address(). Shouldn't this IPv6 source address not the same as the IPv6 destination address of the Echo Request message? A quote from RFC 4443 [chapter 4.2]:

"The source address of an Echo Reply sent in response to a unicast Echo Request message MUST be the same as the destination address of that Echo Request message."

As I understand this would omit the ip6_select_source_address() and
simplifies it to just use the ip6_current_dest_addr() address (previous make sure this is not a multicast address).

I'm using GIT master branch (NOT CVS Head - but this is the most accurate version).
