Struct BanList 

pub struct BanList { /* private fields */ }

The peer groups Zebra has banned for misbehaviour, and when each was banned.

Entries are keyed by peer group — one IPv4 address, or one IPv6 /64 subnet — so a peer cannot dodge its ban by reconnecting from another address it already controls. Bans lapse after BAN_DURATION.

Security

This type owns both of those rules. It deliberately does not expose the underlying map: a caller doing its own lookup would have to remember to map the address to its peer group and to check the ban’s age, and getting either wrong silently stops bans being enforced. Query it with BanList::is_banned.

Correctness

Cloning is cheap, and a clone is a snapshot: the map is shared behind an Arc and copied only when a ban is added. Snapshots stay correct as bans lapse, because BanList::is_banned checks each entry’s age when it is queried, so holders don’t need to be sent a new snapshot.

Implementations

impl BanList

pub fn is_banned(&self, ip: IpAddr) -> bool

Returns true if ip’s peer group is banned, and the ban has not lapsed.

pub fn len(&self) -> usize

Returns the number of banned peer groups, including any whose bans have lapsed but have not been pruned yet.

pub fn is_empty(&self) -> bool

Returns true if no peer group is banned.
