   3 Subject: [PATCH] networking: fix uninitialized memory when displaying IPv6
   4  addresses
   5
   6 After commit 8e74adab0107658e3dc04ed342206272a284f43e
   7 ("libbb: make INET[6]_rresolve use sockaddr2{host,dotted}_noport")
   8 INET_sprint6 uses more than just sin6_addr, it also tries to display the
   9 scope id, which is uninitialized when called from ife_print6.
