Interface flags are set using * SIOCS[L]IFFLAGS ioctl. The three abstractions are : * * 1) Phyiscal interface (phyint) : There is one phyint allocated common * to both IPv4 and IPv6 physical interface instance. * * 2) Phyiscal interface instance (ill) : This encompasses all the state * that is common across all IP addresses assigned to a physical * interface but different between the IPv4 and IPv6 instance. * * 3) Logical interface (ipif) : This has state about a single IP address. * * Values for the various states are derived from the same name space * as applications querying the state using SIOCGIFFLAGS/SIOCGLIFFLAGS * see only one state returned in lifr_flags which is a union of all * the above states/properties. Thus deriving the values from the common * name space makes implementaion easier. All these values are stored in * uint64_t and any other structure/code using these flags should use * uint64_ts. * * As we maintain the interface flags in 3 different flags namely * phyint_flags, ill_flags, ipif_flags we define the following flag values * to be used within the kernel to reduce potential errors. The ones * starting with PHYI_ are supposed to be used with phyint_flags, the ones * starting with ILLF_ are supposed to be used with ill_flags and the ones * starting with IPIF_ are supposed to be used with ipif_flags. If you see * any code with a mismatch i.e phyint_flags & IPIF_UP - it is wrong. Only * PHYI_XXX can be used with phyint_flags. * * NOTE : For EVERY FLAG in if.h, there should be a corresponding value * defined HERE and this is the one that should be USED within IP. We * use IFF_ flags within IP only when we examine lifr_flags. */ #define IFF_PHYINT_FLAGS (IFF_LOOPBACK|IFF_RUNNING|IFF_PROMISC| \ IFF_ALLMULTI|IFF_INTELLIGENT|IFF_MULTI_BCAST|IFF_FAILED|IFF_STANDBY| \ IFF_INACTIVE|IFF_OFFLINE) #define IFF_PHYINTINST_FLAGS (IFF_DEBUG|IFF_NOTRAILERS|IFF_NOARP| \ IFF_MULTICAST|IFF_ROUTER|IFF_NONUD|IFF_NORTEXCH|IFF_IPV4|IFF_IPV6) #define IFF_LOGINT_FLAGS (IFF_UP|IFF_BROADCAST|IFF_POINTOPOINT| \ IFF_UNNUMBERED|IFF_DHCPRUNNING|IFF_PRIVATE|IFF_NOXMIT|IFF_NOLOCAL| \ IFF_DEPRECATED|IFF_ADDRCONF|IFF_ANYCAST|IFF_MIPRUNNING|IFF_NOFAILOVER) #define PHYI_LOOPBACK IFF_LOOPBACK /* is a loopback net */ #define PHYI_RUNNING IFF_RUNNING /* resources allocated */ #define PHYI_PROMISC IFF_PROMISC /* receive all packets */ #define PHYI_ALLMULTI IFF_ALLMULTI /* receive all multi packets */ #define PHYI_INTELLIGENT IFF_INTELLIGENT /* protocol code on board */ #define PHYI_MULTI_BCAST IFF_MULTI_BCAST /* multicast using broadcast */ #define PHYI_FAILED IFF_FAILED /* NIC has failed */ #define PHYI_STANDBY IFF_STANDBY /* Standby NIC */ #define PHYI_INACTIVE IFF_INACTIVE /* Standby active or not ? */ #define PHYI_OFFLINE IFF_OFFLINE /* NIC has been offlined */ #define ILLF_DEBUG IFF_DEBUG /* turn on debugging */ #define ILLF_NOTRAILERS IFF_NOTRAILERS /* avoid use of trailers */ #define ILLF_NOARP IFF_NOARP /* no ARP for this interface */ #define ILLF_MULTICAST IFF_MULTICAST /* supports multicast */ #define ILLF_ROUTER IFF_ROUTER /* router on this interface */ #define ILLF_NONUD IFF_NONUD /* No NUD on this interface */ #define ILLF_NORTEXCH IFF_NORTEXCH /* No routing info exchange */ #define ILLF_IPV4 IFF_IPV4 /* IPv4 interface */ #define ILLF_IPV6 IFF_IPV6 /* IPv6 interface */ #define IPIF_UP IFF_UP /* interface is up */ #define IPIF_BROADCAST IFF_BROADCAST /* broadcast address valid */ #define IPIF_POINTOPOINT IFF_POINTOPOINT /* point-to-point link */ #define IPIF_UNNUMBERED IFF_UNNUMBERED /* non-unique address */ #define IPIF_DHCPRUNNING IFF_DHCPRUNNING /* DHCP controlled interface */ #define IPIF_PRIVATE IFF_PRIVATE /* do not advertise */ #define IPIF_NOXMIT IFF_NOXMIT /* Do not transmit packets */ #define IPIF_NOLOCAL IFF_NOLOCAL /* Just on-link subnet */ #define IPIF_DEPRECATED IFF_DEPRECATED /* address deprecated */ #define IPIF_ADDRCONF IFF_ADDRCONF /* stateless addrconf */ #define IPIF_ANYCAST IFF_ANYCAST /* Anycast address */ #define IPIF_MIPRUNNING IFF_MIPRUNNING /* Mobip Controlled interface */ #define IPIF_NOFAILOVER IFF_NOFAILOVER /* No failover on NIC failure */ extern void illgrp_delete(ill_t *);
