- Subject: [PATCH] networking: fix uninitialized memory when displaying IPv6
- addresses
- After commit 8e74adab0107658e3dc04ed342206272a284f43e
- ("libbb: make INET[6]_rresolve use sockaddr2{host,dotted}_noport")
- INET_sprint6 uses more than just sin6_addr, it also tries to display the
- scope id, which is uninitialized when called from ife_print6.
- Signed-off-by: Felix Fietkau <nbd@nbd.name>
