Interface flags are set using 45 * SIOCS[L]IFFLAGS ioctl. The three abstractions are : 46 * 47 * 1) Physical interface (phyint) : There is one phyint allocated common 48 * to both IPv4 and IPv6 physical interface instance. 49 * 50 * 2) Physical interface instance (ill) : This encompasses all the state 51 * that is common across all IP addresses assigned to a physical 52 * interface but different between the IPv4 and IPv6 instance. 53 * 54 * 3) Logical interface (ipif) : This has state about a single IP address. 55 * 56 * Values for the various states are derived from the same name space 57 * as applications querying the state using SIOCGIFFLAGS/SIOCGLIFFLAGS 58 * see only one state returned in lifr_flags which is a union of all 59 * the above states/properties. Thus deriving the values from the common 60 * name space makes implementation easier. All these values are stored in 61 * uint64_t and any other structure/code using these flags should use 62 * uint64_ts. 63 * 64 * As we maintain the interface flags in 3 different flags namely 65 * phyint_flags, ill_flags, ipif_flags we define the following flag values 66 * to be used within the kernel to reduce potential errors. The ones 67 * starting with PHYI_ are supposed to be used with phyint_flags, the ones 68 * starting with ILLF_ are supposed to be used with ill_flags and the ones 69 * starting with IPIF_ are supposed to be used with ipif_flags. If you see 70 * any code with a mismatch i.e phyint_flags & IPIF_UP - it is wrong. Only 71 * PHYI_XXX can be used with phyint_flags. 72 * 73 * NOTE : For EVERY FLAG in if.h, there should be a corresponding value 74 * defined HERE and this is the one that should be USED within IP. We 75 * use IFF_ flags within IP only when we examine lifr_flags. 76 */ 77 #define IFF_PHYINT_FLAGS (IFF_LOOPBACK|IFF_RUNNING|IFF_PROMISC| \ 78 IFF_ALLMULTI|IFF_INTELLIGENT|IFF_MULTI_BCAST|IFF_FAILED|IFF_STANDBY| \ 79 IFF_INACTIVE|IFF_OFFLINE|IFF_VIRTUAL|IFF_IPMP) 80 81 #define IFF_PHYINTINST_FLAGS (IFF_DEBUG|IFF_NOTRAILERS|IFF_NOARP| \ 82 IFF_MULTICAST|IFF_ROUTER|IFF_NONUD|IFF_NORTEXCH|IFF_IPV4|IFF_IPV6| \ 83 IFF_COS_ENABLED|IFF_FIXEDMTU|IFF_VRRP|IFF_NOACCEPT) 84 85 #define IFF_LOGINT_FLAGS (IFF_UP|IFF_BROADCAST|IFF_POINTOPOINT| \ 86 IFF_UNNUMBERED|IFF_DHCPRUNNING|IFF_PRIVATE|IFF_NOXMIT|IFF_NOLOCAL| \ 87 IFF_DEPRECATED|IFF_ADDRCONF|IFF_ANYCAST|IFF_NOFAILOVER| \ 88 IFF_PREFERRED|IFF_TEMPORARY|IFF_DUPLICATE) 89 90 #define PHYI_LOOPBACK IFF_LOOPBACK /* is a loopback net */ 91 #define PHYI_RUNNING IFF_RUNNING /* resources allocated */ 92 #define PHYI_PROMISC IFF_PROMISC /* receive all packets */ 93 #define PHYI_ALLMULTI IFF_ALLMULTI /* receive all multi packets */ 94 #define PHYI_INTELLIGENT IFF_INTELLIGENT /* protocol code on board */ 95 #define PHYI_MULTI_BCAST IFF_MULTI_BCAST /* multicast using broadcast */ 96 #define PHYI_FAILED IFF_FAILED /* NIC has failed */ 97 #define PHYI_STANDBY IFF_STANDBY /* Standby NIC */ 98 #define PHYI_INACTIVE IFF_INACTIVE /* Standby active or not ? */ 99 #define PHYI_OFFLINE IFF_OFFLINE /* NIC has been offlined */ 100 #define PHYI_VIRTUAL IFF_VIRTUAL /* Will not send or recv pkts */ 101 #define PHYI_IPMP IFF_IPMP /* IPMP meta-interface */ 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 */ 116 117 #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 */ 146 enum 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 };

In particular any data structure that 486 * points to an ipif or ill does not explicitly contribute to a reference on the 487 * ill or ipif. More details may be seen in the block comment above ipif_down(). 488 * Thus in the quiescent state an ill or ipif has a refcnt of zero. Similarly 489 * when a thread exits, there can't be any references on the ipif or ill due to 490 * the exiting thread. 491 * 492 * As a debugging aid, the refhold and refrele functions call into tracing 493 * functions that record the stack trace of the caller and the references 494 * acquired or released by the calling thread, hashed by the structure address 495 * in thread-specific-data (TSD). On thread exit, ip_thread_exit destroys the 496 * hash, and the destructor for the hash entries (th_trace_free) verifies that 497 * there are no outstanding references to the ipif or ill from the exiting 498 * thread. 499 * 500 * In the case of ires and nces, the model is slightly different. Typically each 501 * ire pointing to an nce contributes to the nce_refcnt. Similarly a conn_t 502 * pointing to an ire also contributes to the ire_refcnt. Excluding the above 503 * special cases, the tracing behavior is similar to the tracing on ipif / ill. 504 * Traces are neither recorded nor verified in the exception cases, and the code 505 * is careful to use the right refhold and refrele functions. On thread exit 506 * ire_thread_exit, nce_thread_exit does the verification that are no 507 * outstanding references on the ire / nce from the exiting thread. 508 * 509 * The reference verification is driven from the TSD destructor which calls 510 * into IP's verification function ip_thread_exit. This debugging aid may be 511 * helpful in tracing missing refrele's on a debug kernel. On a non-debug 512 * kernel, these missing refrele's are noticeable only when an interface is 513 * being unplumbed, and the unplumb hangs, long after the missing refrele. On a 514 * debug kernel, the traces (th_trace_t) which contain the stack backtraces can 515 * be examined on a crash dump to locate the missing refrele. 516 */ 517 518 #endif /* _KERNEL */ 519 520 #ifdef __cplusplus 521 } 522 #endif 523 524 #endif /* _INET_IP_IF_H */ 525
