[Dnsmasq-discuss] [PATCH 1/6] Fix -Wshadow: rand64() was mistakenly using its own counter O_o

[Leonid Evdokimov]

It might be security vulnerability as rand64() is basically transmitted
to network in address6_allocate() and it might expose values for some of
next rand16() and rand32() calls as no other function calls rand64().
