Interface flags are set using 43 * SIOCS[L]IFFLAGS ioctl. The three abstractions are : 44 * 45 * 1) Physical interface (phyint) : There is one phyint allocated common 46 * to both IPv4 and IPv6 physical interface instance. 47 * 48 * 2) Physical interface instance (ill) : This encompasses all the state 49 * that is common across all IP addresses assigned to a physical 50 * interface but different between the IPv4 and IPv6 instance. 51 * 52 * 3) Logical interface (ipif) : This has state about a single IP address. 53 * 54 * Values for the various states are derived from the same name space 55 * as applications querying the state using SIOCGIFFLAGS/SIOCGLIFFLAGS 56 * see only one state returned in lifr_flags which is a union of all 57 * the above states/properties. Thus deriving the values from the common 58 * name space makes implementation easier. All these values are stored in 59 * uint64_t and any other structure/code using these flags should use 60 * uint64_ts. 61 * 62 * As we maintain the interface flags in 3 different flags namely 63 * phyint_flags, ill_flags, ipif_flags we define the following flag values 64 * to be used within the kernel to reduce potential errors. The ones 65 * starting with PHYI_ are supposed to be used with phyint_flags, the ones 66 * starting with ILLF_ are supposed to be used with ill_flags and the ones 67 * starting with IPIF_ are supposed to be used with ipif_flags. If you see 68 * any code with a mismatch i.e phyint_flags & IPIF_UP - it is wrong. Only 69 * PHYI_XXX can be used with phyint_flags. 70 * 71 * NOTE : For EVERY FLAG in if.h, there should be a corresponding value 72 * defined HERE and this is the one that should be USED within IP. We 73 * use IFF_ flags within IP only when we examine lifr_flags. 74 */ 75#define IFF_PHYINT_FLAGS (IFF_LOOPBACK|IFF_RUNNING|IFF_PROMISC| \ 76 IFF_ALLMULTI|IFF_INTELLIGENT|IFF_MULTI_BCAST|IFF_FAILED|IFF_STANDBY| \ 77 IFF_INACTIVE|IFF_OFFLINE|IFF_VIRTUAL|IFF_IPMP|IFF_L3PROTECT) 78 79#define IFF_PHYINTINST_FLAGS (IFF_DEBUG|IFF_NOTRAILERS|IFF_NOARP| \ 80 IFF_MULTICAST|IFF_ROUTER|IFF_NONUD|IFF_NORTEXCH|IFF_IPV4|IFF_IPV6| \ 81 IFF_COS_ENABLED|IFF_FIXEDMTU|IFF_VRRP|IFF_NOACCEPT|IFF_NOLINKLOCAL) 82 83#define IFF_LOGINT_FLAGS (IFF_UP|IFF_BROADCAST|IFF_POINTOPOINT| \ 84 IFF_UNNUMBERED|IFF_DHCPRUNNING|IFF_PRIVATE|IFF_NOXMIT|IFF_NOLOCAL| \ 85 IFF_DEPRECATED|IFF_ADDRCONF|IFF_ANYCAST|IFF_NOFAILOVER| \ 86 IFF_PREFERRED|IFF_TEMPORARY|IFF_DUPLICATE) 87 88#define PHYI_LOOPBACK IFF_LOOPBACK /* is a loopback net */ 89#define PHYI_RUNNING IFF_RUNNING /* resources allocated */ 90#define PHYI_PROMISC IFF_PROMISC /* receive all packets */ 91#define PHYI_ALLMULTI IFF_ALLMULTI /* receive all multi packets */ 92#define PHYI_INTELLIGENT IFF_INTELLIGENT /* protocol code on board */ 93#define PHYI_MULTI_BCAST IFF_MULTI_BCAST /* multicast using broadcast */ 94#define PHYI_FAILED IFF_FAILED /* NIC has failed */ 95#define PHYI_STANDBY IFF_STANDBY /* Standby NIC */ 96#define PHYI_INACTIVE IFF_INACTIVE /* Standby active or not ? */ 97#define PHYI_OFFLINE IFF_OFFLINE /* NIC has been offlined */ 98#define PHYI_VIRTUAL IFF_VIRTUAL /* Will not send or recv pkts */ 99#define PHYI_IPMP IFF_IPMP /* IPMP meta-interface */ 100#define PHYI_L3PROTECT IFF_L3PROTECT /* Layer-3 protected */ 101 102#define ILLF_DEBUG IFF_DEBUG /* turn on debugging */ 103#define ILLF_NOTRAILERS IFF_NOTRAILERS /* avoid use of trailers */ 104#define ILLF_NOARP IFF_NOARP /* no ARP for this interface */ 105#define ILLF_MULTICAST IFF_MULTICAST /* supports multicast */ 106#define ILLF_ROUTER IFF_ROUTER /* router on this interface */ 107#define ILLF_NONUD IFF_NONUD /* No NUD on this interface */ 108#define ILLF_NORTEXCH IFF_NORTEXCH /* No routing info exchange */ 109#define ILLF_IPV4 IFF_IPV4 /* IPv4 interface */ 110#define ILLF_IPV6 IFF_IPV6 /* IPv6 interface */ 111#define ILLF_COS_ENABLED IFF_COS_ENABLED /* Is CoS marking supported */ 112#define ILLF_FIXEDMTU IFF_FIXEDMTU /* set with SIOCSLIFMTU */ 113#define ILLF_VRRP IFF_VRRP /* managed by VRRP */ 114#define ILLF_NOACCEPT IFF_NOACCEPT /* accept only ND messagees */ 115#define ILLF_NOLINKLOCAL IFF_NOLINKLOCAL /* No default linklocal */ 116 117#define IPIF_UP IFF_UP /* interface is up */ 118#define IPIF_BROADCAST IFF_BROADCAST /* broadcast address valid */ 119#define IPIF_POINTOPOINT IFF_POINTOPOINT /* point-to-point link */ 120#define IPIF_UNNUMBERED IFF_UNNUMBERED /* non-unique address */ 121#define IPIF_DHCPRUNNING IFF_DHCPRUNNING /* DHCP controlled interface */ 122#define IPIF_PRIVATE IFF_PRIVATE /* do not advertise */ 123#define IPIF_NOXMIT IFF_NOXMIT /* Do not transmit packets */ 124#define IPIF_NOLOCAL IFF_NOLOCAL /* Just on-link subnet */ 125#define IPIF_DEPRECATED IFF_DEPRECATED /* address deprecated */ 126#define IPIF_ADDRCONF IFF_ADDRCONF /* stateless addrconf */ 127#define IPIF_ANYCAST IFF_ANYCAST /* Anycast address */ 128#define IPIF_NOFAILOVER IFF_NOFAILOVER /* No failover on NIC failure */ 129#define IPIF_PREFERRED IFF_PREFERRED /* Prefer as source address */ 130#define IPIF_TEMPORARY IFF_TEMPORARY /* RFC3041 */ 131#define IPIF_DUPLICATE IFF_DUPLICATE /* address is in use */ 132 133#ifdef DEBUG 134#define ILL_MAC_PERIM_HELD(ill) ill_mac_perim_held(ill) 135#else 136#define ILL_MAC_PERIM_HELD(ill) 137#endif 138 139/* 140 * match flags for ipif_lookup_addr_common* functions 141 */ 142#define IPIF_MATCH_ILLGRP 0x00000001 143#define IPIF_MATCH_NONDUP 0x00000002 144 145/* for ipif_resolver_up */ 146enum ip_resolver_action { 147 Res_act_initial, /* initial address establishment */ 148 Res_act_rebind, /* IPMP address rebind (new hwaddr) */ 149 Res_act_defend, /* address defense */ 150 Res_act_none /* do nothing */ 151};

495 496/* 497 * Notes on reference tracing on ill, ipif, ire, nce data structures: 498 * 499 * The current model of references on an ipif or ill is purely based on threads 500 * acquiring a reference by doing a lookup on the ill or ipif or by calling a 501 * refhold function on the ill or ipif. In particular any data structure that 502 * points to an ipif or ill does not explicitly contribute to a reference on the 503 * ill or ipif. More details may be seen in the block comment above ipif_down(). 504 * Thus in the quiescent state an ill or ipif has a refcnt of zero. Similarly 505 * when a thread exits, there can't be any references on the ipif or ill due to 506 * the exiting thread. 507 * 508 * As a debugging aid, the refhold and refrele functions call into tracing 509 * functions that record the stack trace of the caller and the references 510 * acquired or released by the calling thread, hashed by the structure address 511 * in thread-specific-data (TSD). On thread exit, ip_thread_exit destroys the 512 * hash, and the destructor for the hash entries (th_trace_free) verifies that 513 * there are no outstanding references to the ipif or ill from the exiting 514 * thread. 515 * 516 * In the case of ires and nces, the model is slightly different. Typically each 517 * ire pointing to an nce contributes to the nce_refcnt. Similarly a conn_t 518 * pointing to an ire also contributes to the ire_refcnt. Excluding the above 519 * special cases, the tracing behavior is similar to the tracing on ipif / ill. 520 * Traces are neither recorded nor verified in the exception cases, and the code 521 * is careful to use the right refhold and refrele functions. On thread exit 522 * ire_thread_exit, nce_thread_exit does the verification that are no 523 * outstanding references on the ire / nce from the exiting thread. 524 * 525 * The reference verification is driven from the TSD destructor which calls 526 * into IP's verification function ip_thread_exit. This debugging aid may be 527 * helpful in tracing missing refrele's on a debug kernel. On a non-debug 528 * kernel, these missing refrele's are noticeable only when an interface is 529 * being unplumbed, and the unplumb hangs, long after the missing refrele. On a 530 * debug kernel, the traces (th_trace_t) which contain the stack backtraces can 531 * be examined on a crash dump to locate the missing refrele. 532 */ 533 534#endif /* _KERNEL */ 535 536#ifdef __cplusplus 537} 538#endif 539 540#endif /* _INET_IP_IF_H */ 541
