Interface flags are set using 44 * SIOCS[L]IFFLAGS ioctl. The three abstractions are : 45 * 46 * 1) Physical interface (phyint) : There is one phyint allocated common 47 * to both IPv4 and IPv6 physical interface instance. 48 * 49 * 2) Physical interface instance (ill) : This encompasses all the state 50 * that is common across all IP addresses assigned to a physical 51 * interface but different between the IPv4 and IPv6 instance. 52 * 53 * 3) Logical interface (ipif) : This has state about a single IP address. 54 * 55 * Values for the various states are derived from the same name space 56 * as applications querying the state using SIOCGIFFLAGS/SIOCGLIFFLAGS 57 * see only one state returned in lifr_flags which is a union of all 58 * the above states/properties. Thus deriving the values from the common 59 * name space makes implementation easier. All these values are stored in 60 * uint64_t and any other structure/code using these flags should use 61 * uint64_ts. 62 * 63 * As we maintain the interface flags in 3 different flags namely 64 * phyint_flags, ill_flags, ipif_flags we define the following flag values 65 * to be used within the kernel to reduce potential errors. The ones 66 * starting with PHYI_ are supposed to be used with phyint_flags, the ones 67 * starting with ILLF_ are supposed to be used with ill_flags and the ones 68 * starting with IPIF_ are supposed to be used with ipif_flags. If you see 69 * any code with a mismatch i.e phyint_flags & IPIF_UP - it is wrong. Only 70 * PHYI_XXX can be used with phyint_flags. 71 * 72 * NOTE : For EVERY FLAG in if.h, there should be a corresponding value 73 * defined HERE and this is the one that should be USED within IP. We 74 * use IFF_ flags within IP only when we examine lifr_flags. 75 */ 76 #define IFF_PHYINT_FLAGS (IFF_LOOPBACK|IFF_RUNNING|IFF_PROMISC| \ 77 IFF_ALLMULTI|IFF_INTELLIGENT|IFF_MULTI_BCAST|IFF_FAILED|IFF_STANDBY| \ 78 IFF_INACTIVE|IFF_OFFLINE|IFF_VIRTUAL|IFF_IPMP|IFF_L3PROTECT) 79 80 #define IFF_PHYINTINST_FLAGS (IFF_DEBUG|IFF_NOTRAILERS|IFF_NOARP| \ 81 IFF_MULTICAST|IFF_ROUTER|IFF_NONUD|IFF_NORTEXCH|IFF_IPV4|IFF_IPV6| \ 82 IFF_COS_ENABLED|IFF_FIXEDMTU|IFF_VRRP|IFF_NOACCEPT|IFF_NOLINKLOCAL) 83 84 #define IFF_LOGINT_FLAGS (IFF_UP|IFF_BROADCAST|IFF_POINTOPOINT| \ 85 IFF_UNNUMBERED|IFF_DHCPRUNNING|IFF_PRIVATE|IFF_NOXMIT|IFF_NOLOCAL| \ 86 IFF_DEPRECATED|IFF_ADDRCONF|IFF_ANYCAST|IFF_NOFAILOVER| \ 87 IFF_PREFERRED|IFF_TEMPORARY|IFF_DUPLICATE) 88 89 #define PHYI_LOOPBACK IFF_LOOPBACK /* is a loopback net */ 90 #define PHYI_RUNNING IFF_RUNNING /* resources allocated */ 91 #define PHYI_PROMISC IFF_PROMISC /* receive all packets */ 92 #define PHYI_ALLMULTI IFF_ALLMULTI /* receive all multi packets */ 93 #define PHYI_INTELLIGENT IFF_INTELLIGENT /* protocol code on board */ 94 #define PHYI_MULTI_BCAST IFF_MULTI_BCAST /* multicast using broadcast */ 95 #define PHYI_FAILED IFF_FAILED /* NIC has failed */ 96 #define PHYI_STANDBY IFF_STANDBY /* Standby NIC */ 97 #define PHYI_INACTIVE IFF_INACTIVE /* Standby active or not ? */ 98 #define PHYI_OFFLINE IFF_OFFLINE /* NIC has been offlined */ 99 #define PHYI_VIRTUAL IFF_VIRTUAL /* Will not send or recv pkts */ 100 #define PHYI_IPMP IFF_IPMP /* IPMP meta-interface */ 101 #define PHYI_L3PROTECT IFF_L3PROTECT /* Layer-3 protected */ 102 103 #define ILLF_DEBUG IFF_DEBUG /* turn on debugging */ 104 #define ILLF_NOTRAILERS IFF_NOTRAILERS /* avoid use of trailers */ 105 #define ILLF_NOARP IFF_NOARP /* no ARP for this interface */ 106 #define ILLF_MULTICAST IFF_MULTICAST /* supports multicast */ 107 #define ILLF_ROUTER IFF_ROUTER /* router on this interface */ 108 #define ILLF_NONUD IFF_NONUD /* No NUD on this interface */ 109 #define ILLF_NORTEXCH IFF_NORTEXCH /* No routing info exchange */ 110 #define ILLF_IPV4 IFF_IPV4 /* IPv4 interface */ 111 #define ILLF_IPV6 IFF_IPV6 /* IPv6 interface */ 112 #define ILLF_COS_ENABLED IFF_COS_ENABLED /* Is CoS marking supported */ 113 #define ILLF_FIXEDMTU IFF_FIXEDMTU /* set with SIOCSLIFMTU */ 114 #define ILLF_VRRP IFF_VRRP /* managed by VRRP */ 115 #define ILLF_NOACCEPT IFF_NOACCEPT /* accept only ND messagees */ 116 #define ILLF_NOLINKLOCAL IFF_NOLINKLOCAL /* No default linklocal */ 117 118 #define IPIF_UP IFF_UP /* interface is up */ 119 #define IPIF_BROADCAST IFF_BROADCAST /* broadcast address valid */ 120 #define IPIF_POINTOPOINT IFF_POINTOPOINT /* point-to-point link */ 121 #define IPIF_UNNUMBERED IFF_UNNUMBERED /* non-unique address */ 122 #define IPIF_DHCPRUNNING IFF_DHCPRUNNING /* DHCP controlled interface */ 123 #define IPIF_PRIVATE IFF_PRIVATE /* do not advertise */ 124 #define IPIF_NOXMIT IFF_NOXMIT /* Do not transmit packets */ 125 #define IPIF_NOLOCAL IFF_NOLOCAL /* Just on-link subnet */ 126 #define IPIF_DEPRECATED IFF_DEPRECATED /* address deprecated */ 127 #define IPIF_ADDRCONF IFF_ADDRCONF /* stateless addrconf */ 128 #define IPIF_ANYCAST IFF_ANYCAST /* Anycast address */ 129 #define IPIF_NOFAILOVER IFF_NOFAILOVER /* No failover on NIC failure */ 130 #define IPIF_PREFERRED IFF_PREFERRED /* Prefer as source address */ 131 #define IPIF_TEMPORARY IFF_TEMPORARY /* RFC3041 */ 132 #define IPIF_DUPLICATE IFF_DUPLICATE /* address is in use */ 133 134 #ifdef DEBUG 135 #define ILL_MAC_PERIM_HELD(ill) ill_mac_perim_held(ill) 136 #else 137 #define ILL_MAC_PERIM_HELD(ill) 138 #endif 139 140 /* 141 * match flags for ipif_lookup_addr_common* functions 142 */ 143 #define IPIF_MATCH_ILLGRP 0x00000001 144 #define IPIF_MATCH_NONDUP 0x00000002 145 146 /* for ipif_resolver_up */ 147 enum ip_resolver_action { 148 Res_act_initial, /* initial address establishment */ 149 Res_act_rebind, /* IPMP address rebind (new hwaddr) */ 150 Res_act_defend, /* address defense */ 151 Res_act_none /* do nothing */ 152 };

491 492 /* 493 * Notes on reference tracing on ill, ipif, ire, nce data structures: 494 * 495 * The current model of references on an ipif or ill is purely based on threads 496 * acquiring a reference by doing a lookup on the ill or ipif or by calling a 497 * refhold function on the ill or ipif. In particular any data structure that 498 * points to an ipif or ill does not explicitly contribute to a reference on the 499 * ill or ipif. More details may be seen in the block comment above ipif_down(). 500 * Thus in the quiescent state an ill or ipif has a refcnt of zero. Similarly 501 * when a thread exits, there can't be any references on the ipif or ill due to 502 * the exiting thread. 503 * 504 * As a debugging aid, the refhold and refrele functions call into tracing 505 * functions that record the stack trace of the caller and the references 506 * acquired or released by the calling thread, hashed by the structure address 507 * in thread-specific-data (TSD). On thread exit, ip_thread_exit destroys the 508 * hash, and the destructor for the hash entries (th_trace_free) verifies that 509 * there are no outstanding references to the ipif or ill from the exiting 510 * thread. 511 * 512 * In the case of ires and nces, the model is slightly different. Typically each 513 * ire pointing to an nce contributes to the nce_refcnt. Similarly a conn_t 514 * pointing to an ire also contributes to the ire_refcnt. Excluding the above 515 * special cases, the tracing behavior is similar to the tracing on ipif / ill. 516 * Traces are neither recorded nor verified in the exception cases, and the code 517 * is careful to use the right refhold and refrele functions. On thread exit 518 * ire_thread_exit, nce_thread_exit does the verification that are no 519 * outstanding references on the ire / nce from the exiting thread. 520 * 521 * The reference verification is driven from the TSD destructor which calls 522 * into IP's verification function ip_thread_exit. This debugging aid may be 523 * helpful in tracing missing refrele's on a debug kernel. On a non-debug 524 * kernel, these missing refrele's are noticeable only when an interface is 525 * being unplumbed, and the unplumb hangs, long after the missing refrele. On a 526 * debug kernel, the traces (th_trace_t) which contain the stack backtraces can 527 * be examined on a crash dump to locate the missing refrele. 528 */ 529 530 #endif /* _KERNEL */ 531 532 #ifdef __cplusplus 533 } 534 #endif 535 536 #endif /* _INET_IP_IF_H */ 537
