Types ¶
type Key ¶
type Key struct {
Prefixlen uint32 `align:"lpm_key"`
ClusterID uint16 `align:"cluster_id"`
Pad1 uint8 `align:"pad1"`
Family uint8 `align:"family"`
// represents both IPv6 and IPv4 (in the lowest four bytes)
IP types.IPv6 `align:"$union0"`
}
Key implements the bpf.MapKey interface.
Must be in sync with struct ipcache_key in <bpf/lib/eps.h>
type Map ¶
Map represents an IPCache BPF map.
func IPCacheMap ¶
IPCacheMap gets the ipcache Map singleton. If it has not already been done, this also initializes the Map.
type RemoteEndpointInfo ¶
type RemoteEndpointInfo struct {
SecurityIdentity uint32 `align:"sec_identity"`
// represents both IPv6 and IPv4 (in the lowest four bytes)
TunnelEndpoint types.IPv6 `align:"tunnel_endpoint"`
Key uint8 `align:"key"`
Flags RemoteEndpointInfoFlags `align:"flag_skip_tunnel"`
// contains filtered or unexported fields
}
RemoteEndpointInfo implements the bpf.MapValue interface. It contains the security identity of a remote endpoint.
func NewValue ¶ added in v1.18.0
func NewValue(secID uint32, tunnelEndpoint netip.Addr, key uint8, flags RemoteEndpointInfoFlags) RemoteEndpointInfo
NewValue returns a RemoteEndpointInfo based on the provided security identity, tunnel endpoint IP, IPsec key, and flags. The address family is automatically detected.
func (*RemoteEndpointInfo) GetTunnelEndpoint ¶ added in v1.18.0
func (v *RemoteEndpointInfo) GetTunnelEndpoint() netip.Addr
func (*RemoteEndpointInfo) New ¶
func (v *RemoteEndpointInfo) New() bpf.MapValue
func (*RemoteEndpointInfo) String ¶
func (v *RemoteEndpointInfo) String() string
type RemoteEndpointInfoFlags ¶ added in v1.16.0
type RemoteEndpointInfoFlags uint8
RemoteEndpointInfoFlags represents various flags that can be attached to remote endpoints in the IPCache.
const ( // FlagSkipTunnel can be applied to a remote endpoint to signal that // packets destined for said endpoint shall not be forwarded through // a VXLAN/Geneve tunnel, regardless of Cilium's configuration. FlagSkipTunnel RemoteEndpointInfoFlags = 1 << iota // FlagHasTunnelEndpoint is set when the tunnel endpoint is not null. It // aims to simplify the logic compared to checking the IPv6 address. FlagHasTunnelEndpoint // FlagIPv6TunnelEndpoint is set when the tunnel endpoint IP address // is an IPv6 address. FlagIPv6TunnelEndpoint // FlagRemoteCluster is set when the node is in a remote cluster. // It's always unset when clustermesh is disabled or for pods. FlagRemoteCluster )
func (RemoteEndpointInfoFlags) String ¶ added in v1.16.0
func (f RemoteEndpointInfoFlags) String() string
String returns a human-readable representation of the flags present in the RemoteEndpointInfoFlags. The output format is the string name of each flag contained in the flag set, separated by a comma. If no flags are set, then "<none>" is returned.
