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

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