Interface flags are set using 45 0 stevel * SIOCS[L]IFFLAGS ioctl. The three abstractions are : 46 0 stevel * 47 0 stevel * 1) Physical interface (phyint) : There is one phyint allocated common 48 0 stevel * to both IPv4 and IPv6 physical interface instance. 49 0 stevel * 50 0 stevel * 2) Physical interface instance (ill) : This encompasses all the state 51 0 stevel * that is common across all IP addresses assigned to a physical 52 0 stevel * interface but different between the IPv4 and IPv6 instance. 53 0 stevel * 54 0 stevel * 3) Logical interface (ipif) : This has state about a single IP address. 55 0 stevel * 56 0 stevel * Values for the various states are derived from the same name space 57 0 stevel * as applications querying the state using SIOCGIFFLAGS/SIOCGLIFFLAGS 58 0 stevel * see only one state returned in lifr_flags which is a union of all 59 0 stevel * the above states/properties. Thus deriving the values from the common 60 0 stevel * name space makes implementation easier. All these values are stored in 61 0 stevel * uint64_t and any other structure/code using these flags should use 62 0 stevel * uint64_ts. 63 0 stevel * 64 0 stevel * As we maintain the interface flags in 3 different flags namely 65 0 stevel * phyint_flags, ill_flags, ipif_flags we define the following flag values 66 0 stevel * to be used within the kernel to reduce potential errors. The ones 67 0 stevel * starting with PHYI_ are supposed to be used with phyint_flags, the ones 68 0 stevel * starting with ILLF_ are supposed to be used with ill_flags and the ones 69 0 stevel * starting with IPIF_ are supposed to be used with ipif_flags. If you see 70 0 stevel * any code with a mismatch i.e phyint_flags & IPIF_UP - it is wrong. Only 71 0 stevel * PHYI_XXX can be used with phyint_flags. 72 0 stevel * 73 0 stevel * NOTE : For EVERY FLAG in if.h, there should be a corresponding value 74 0 stevel * defined HERE and this is the one that should be USED within IP.

In particular any data structure that 486 4136 nordmark * points to an ipif or ill does not explicitly contribute to a reference on the 487 4136 nordmark * ill or ipif. More details may be seen in the block comment above ipif_down(). 488 4136 nordmark * Thus in the quiescent state an ill or ipif has a refcnt of zero. Similarly 489 4136 nordmark * when a thread exits, there can't be any references on the ipif or ill due to 490 4136 nordmark * the exiting thread. 491 4136 nordmark * 492 4136 nordmark * As a debugging aid, the refhold and refrele functions call into tracing 493 4136 nordmark * functions that record the stack trace of the caller and the references 494 5023 carlsonj * acquired or released by the calling thread, hashed by the structure address 495 5023 carlsonj * in thread-specific-data (TSD). On thread exit, ip_thread_exit destroys the 496 5023 carlsonj * hash, and the destructor for the hash entries (th_trace_free) verifies that 497 5023 carlsonj * there are no outstanding references to the ipif or ill from the exiting 498 5023 carlsonj * thread. 499 4136 nordmark * 500 4136 nordmark * In the case of ires and nces, the model is slightly different. Typically each 501 4136 nordmark * ire pointing to an nce contributes to the nce_refcnt. Similarly a conn_t 502 4136 nordmark * pointing to an ire also contributes to the ire_refcnt. Excluding the above 503 4136 nordmark * special cases, the tracing behavior is similar to the tracing on ipif / ill. 504 4136 nordmark * Traces are neither recorded nor verified in the exception cases, and the code 505 4136 nordmark * is careful to use the right refhold and refrele functions. On thread exit 506 4136 nordmark * ire_thread_exit, nce_thread_exit does the verification that are no 507 4136 nordmark * outstanding references on the ire / nce from the exiting thread. 508 4136 nordmark * 509 5023 carlsonj * The reference verification is driven from the TSD destructor which calls 510 5023 carlsonj * into IP's verification function ip_thread_exit. This debugging aid may be 511 5023 carlsonj * helpful in tracing missing refrele's on a debug kernel. On a non-debug 512 5023 carlsonj * kernel, these missing refrele's are noticeable only when an interface is 513 5023 carlsonj * being unplumbed, and the unplumb hangs, long after the missing refrele. On a 514 5023 carlsonj * debug kernel, the traces (th_trace_t) which contain the stack backtraces can 515 5023 carlsonj * be examined on a crash dump to locate the missing refrele. 516 4136 nordmark */ 517 4136 nordmark 518 0 stevel #endif /* _KERNEL */ 519 0 stevel 520 0 stevel #ifdef __cplusplus 521 0 stevel } 522 0 stevel #endif 523 0 stevel 524 0 stevel #endif /* _INET_IP_IF_H */ 525
