Interface flags are set using 49 * SIOCS[L]IFFLAGS ioctl. The three abstractions are : 50 * 51 * 1) Physical interface (phyint) : There is one phyint allocated common 52 * to both IPv4 and IPv6 physical interface instance. 53 * 54 * 2) Physical interface instance (ill) : This encompasses all the state 55 * that is common across all IP addresses assigned to a physical 56 * interface but different between the IPv4 and IPv6 instance. 57 * 58 * 3) Logical interface (ipif) : This has state about a single IP address. 59 * 60 * Values for the various states are derived from the same name space 61 * as applications querying the state using SIOCGIFFLAGS/SIOCGLIFFLAGS 62 * see only one state returned in lifr_flags which is a union of all 63 * the above states/properties. Thus deriving the values from the common 64 * name space makes implementation easier. All these values are stored in 65 * uint64_t and any other structure/code using these flags should use 66 * uint64_ts. 67 * 68 * As we maintain the interface flags in 3 different flags namely 69 * phyint_flags, ill_flags, ipif_flags we define the following flag values 70 * to be used within the kernel to reduce potential errors. The ones 71 * starting with PHYI_ are supposed to be used with phyint_flags, the ones 72 * starting with ILLF_ are supposed to be used with ill_flags and the ones 73 * starting with IPIF_ are supposed to be used with ipif_flags. If you see 74 * any code with a mismatch i.e phyint_flags & IPIF_UP - it is wrong. Only 75 * PHYI_XXX can be used with phyint_flags. 76 * 77 * NOTE : For EVERY FLAG in if.h, there should be a corresponding value 78 * defined HERE and this is the one that should be USED within IP. We 79 * use IFF_ flags within IP only when we examine lifr_flags. 80 */ 81 #define IFF_PHYINT_FLAGS (IFF_LOOPBACK|IFF_RUNNING|IFF_PROMISC| \ 82 IFF_ALLMULTI|IFF_INTELLIGENT|IFF_MULTI_BCAST|IFF_FAILED|IFF_STANDBY| \ 83 IFF_INACTIVE|IFF_OFFLINE|IFF_VIRTUAL) 84 85 #define IFF_PHYINTINST_FLAGS (IFF_DEBUG|IFF_NOTRAILERS|IFF_NOARP| \ 86 IFF_MULTICAST|IFF_ROUTER|IFF_NONUD|IFF_NORTEXCH|IFF_IPV4|IFF_IPV6| \ 87 IFF_XRESOLV|IFF_COS_ENABLED) 88 89 #define IFF_LOGINT_FLAGS (IFF_UP|IFF_BROADCAST|IFF_POINTOPOINT| \ 90 IFF_UNNUMBERED|IFF_DHCPRUNNING|IFF_PRIVATE|IFF_NOXMIT|IFF_NOLOCAL| \ 91 IFF_DEPRECATED|IFF_ADDRCONF|IFF_ANYCAST|IFF_NOFAILOVER| \ 92 IFF_PREFERRED|IFF_TEMPORARY|IFF_FIXEDMTU|IFF_DUPLICATE) 93 94 #define IPIF_REPL_CHECK(to_ipif, failback_cmd) \ 95 (((to_ipif)->ipif_replace_zero) || ((failback_cmd) && \ 96 !(to_ipif)->ipif_isv6 && !((to_ipif)->ipif_flags & IPIF_UP) && \ 97 (to_ipif)->ipif_lcl_addr == INADDR_ANY)) 98 99 #define PHYI_LOOPBACK IFF_LOOPBACK /* is a loopback net */ 100 #define PHYI_RUNNING IFF_RUNNING /* resources allocated */ 101 #define PHYI_PROMISC IFF_PROMISC /* receive all packets */ 102 #define PHYI_ALLMULTI IFF_ALLMULTI /* receive all multi packets */ 103 #define PHYI_INTELLIGENT IFF_INTELLIGENT /* protocol code on board */ 104 #define PHYI_MULTI_BCAST IFF_MULTI_BCAST /* multicast using broadcast */ 105 #define PHYI_FAILED IFF_FAILED /* NIC has failed */ 106 #define PHYI_STANDBY IFF_STANDBY /* Standby NIC */ 107 #define PHYI_INACTIVE IFF_INACTIVE /* Standby active or not ? */ 108 #define PHYI_OFFLINE IFF_OFFLINE /* NIC has been offlined */ 109 #define PHYI_VIRTUAL IFF_VIRTUAL /* Will not send or recv pkts */ 110 111 #define ILLF_DEBUG IFF_DEBUG /* turn on debugging */ 112 #define ILLF_NOTRAILERS IFF_NOTRAILERS /* avoid use of trailers */ 113 #define ILLF_NOARP IFF_NOARP /* no ARP for this interface */ 114 #define ILLF_MULTICAST IFF_MULTICAST /* supports multicast */ 115 #define ILLF_ROUTER IFF_ROUTER /* router on this interface */ 116 #define ILLF_NONUD IFF_NONUD /* No NUD on this interface */ 117 #define ILLF_NORTEXCH IFF_NORTEXCH /* No routing info exchange */ 118 #define ILLF_IPV4 IFF_IPV4 /* IPv4 interface */ 119 #define ILLF_IPV6 IFF_IPV6 /* IPv6 interface */ 120 #define ILLF_XRESOLV IFF_XRESOLV /* IPv6 external resolver */ 121 #define ILLF_COS_ENABLED IFF_COS_ENABLED /* Is CoS marking supported */ 122 123 #define IPIF_UP IFF_UP /* interface is up */ 124 #define IPIF_BROADCAST IFF_BROADCAST /* broadcast address valid */ 125 #define IPIF_POINTOPOINT IFF_POINTOPOINT /* point-to-point link */ 126 #define IPIF_UNNUMBERED IFF_UNNUMBERED /* non-unique address */ 127 #define IPIF_DHCPRUNNING IFF_DHCPRUNNING /* DHCP controlled interface */ 128 #define IPIF_PRIVATE IFF_PRIVATE /* do not advertise */ 129 #define IPIF_NOXMIT IFF_NOXMIT /* Do not transmit packets */ 130 #define IPIF_NOLOCAL IFF_NOLOCAL /* Just on-link subnet */ 131 #define IPIF_DEPRECATED IFF_DEPRECATED /* address deprecated */ 132 #define IPIF_ADDRCONF IFF_ADDRCONF /* stateless addrconf */ 133 #define IPIF_ANYCAST IFF_ANYCAST /* Anycast address */ 134 #define IPIF_NOFAILOVER IFF_NOFAILOVER /* No failover on NIC failure */ 135 #define IPIF_PREFERRED IFF_PREFERRED /* Prefer as source address */ 136 #define IPIF_TEMPORARY IFF_TEMPORARY /* RFC3041 */ 137 #define IPIF_FIXEDMTU IFF_FIXEDMTU /* set with SIOCSLIFMTU */ 138 #define IPIF_DUPLICATE IFF_DUPLICATE /* address is in use */ 139 140 /* Source selection values for ipif_select_source_v6 */ 141 #define RESTRICT_TO_NONE 0x0 /* No restriction in source selection */ 142 #define RESTRICT_TO_GROUP 0x1 /* Restrict to IPMP group */ 143 #define RESTRICT_TO_ILL 0x2 /* Restrict to ILL */ 144 145 #ifdef DEBUG 146 #define ILL_MAC_PERIM_HELD(ill) ill_mac_perim_held(ill) 147 #else 148 #define ILL_MAC_PERIM_HELD(ill) 149 #endif 150 151 /* for ipif_resolver_up */ 152 enum ip_resolver_action { 153 Res_act_initial, /* initial address establishment */ 154 Res_act_move, /* address move (IPMP, new DL addr) */ 155 Res_act_defend /* address defense */ 156 };

487 488 /* 489 * Notes on reference tracing on ill, ipif, ire, nce data structures: 490 * 491 * The current model of references on an ipif or ill is purely based on threads 492 * acquiring a reference by doing a lookup on the ill or ipif or by calling a 493 * refhold function on the ill or ipif. In particular any data structure that 494 * points to an ipif or ill does not explicitly contribute to a reference on the 495 * ill or ipif. More details may be seen in the block comment above ipif_down(). 496 * Thus in the quiescent state an ill or ipif has a refcnt of zero. Similarly 497 * when a thread exits, there can't be any references on the ipif or ill due to 498 * the exiting thread. 499 * 500 * As a debugging aid, the refhold and refrele functions call into tracing 501 * functions that record the stack trace of the caller and the references 502 * acquired or released by the calling thread, hashed by the structure address 503 * in thread-specific-data (TSD). On thread exit, ip_thread_exit destroys the 504 * hash, and the destructor for the hash entries (th_trace_free) verifies that 505 * there are no outstanding references to the ipif or ill from the exiting 506 * thread. 507 * 508 * In the case of ires and nces, the model is slightly different. Typically each 509 * ire pointing to an nce contributes to the nce_refcnt. Similarly a conn_t 510 * pointing to an ire also contributes to the ire_refcnt. Excluding the above 511 * special cases, the tracing behavior is similar to the tracing on ipif / ill. 512 * Traces are neither recorded nor verified in the exception cases, and the code 513 * is careful to use the right refhold and refrele functions. On thread exit 514 * ire_thread_exit, nce_thread_exit does the verification that are no 515 * outstanding references on the ire / nce from the exiting thread. 516 * 517 * The reference verification is driven from the TSD destructor which calls 518 * into IP's verification function ip_thread_exit. This debugging aid may be 519 * helpful in tracing missing refrele's on a debug kernel. On a non-debug 520 * kernel, these missing refrele's are noticeable only when an interface is 521 * being unplumbed, and the unplumb hangs, long after the missing refrele. On a 522 * debug kernel, the traces (th_trace_t) which contain the stack backtraces can 523 * be examined on a crash dump to locate the missing refrele. 524 */ 525 526 #endif /* _KERNEL */ 527 528 #ifdef __cplusplus 529 } 530 #endif 531 532 #endif /* _INET_IP_IF_H */ 533
