Expand description

Runtime information returned by the kernel for a session.

Fields (Non-exhaustive)§

This struct is marked as non-exhaustive
Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.
§tunnel_id: TunnelId

Parent tunnel identifier.

§peer_tunnel_id: TunnelId

Peer tunnel identifier of the parent tunnel.

§session_id: SessionId

Local session identifier.

§peer_session_id: SessionId

Peer session identifier.

§pseudowire_type: PseudowireType

Session pseudowire type.

§l2spec_type: Option<L2SpecType>

Session L2-specific sublayer type, when the kernel reports it.

Linux accepts L2TP_ATTR_L2SPEC_TYPE on creation but omits it from session replies, so this is None on current kernels and the value given at creation cannot be read back.

§cookie: Cookie

Local session cookie; empty when none is set.

§peer_cookie: Cookie

Peer session cookie; empty when none is set.

§recv_seq: bool

Receive sequence checking state.

§send_seq: bool

Transmit sequence number state.

§lns_mode: bool

LNS mode state.

§recv_timeout_ms: Option<u64>

Receive timeout in milliseconds.

§ifname: Option<L2tpIfName>

The session interface name as recorded when the session was created.

The kernel copies the l2tpeth device’s name into the session once, right after creating the device, and never updates it: an interface renamed afterwards with rtnetlink keeps being reported, and matched by the *_by_ifname lookups, under this original name. Applications that rename these interfaces, or run where udev or networkd rename them, must track the device by its interface index: SessionHandle::ifindex captures it from the kernel’s registration broadcast when the session is created. A lookup of this name with L2tpIfNameExt::index is only correct while the interface still bears it, and the kernel does not report the index itself. Request an explicit, unique name in SessionConfig::ifname rather than relying on the kernel’s l2tpeth%d pool, so that no other device can hold the name while this one does.

§using_ipsec: bool

Whether IPsec offload/protection is in use.
