41 * Interface flags actually represent the state/properties of 3 different
42 * abstractions of interfaces in IP. Interface flags are set using
43 * SIOCS[L]IFFLAGS ioctl. The three abstractions are :
45 * 1) Physical interface (phyint) : There is one phyint allocated common
46 * to both IPv4 and IPv6 physical interface instance.
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.
52 * 3) Logical interface (ipif) : This has state about a single IP address.
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
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.
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.

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