Becoming "writer" on an IPSQ 1041 8485 Peter * ensures that no other threads can become "writer" on any IPSQs sharing that 1042 8485 Peter * IPSQ's xop until the writer thread is done. 1043 0 stevel * 1044 8485 Peter * Each phyint points to one IPSQ that remains fixed over the phyint's life. 1045 8485 Peter * Each IPSQ points to one xop that can change over the IPSQ's life. If a 1046 8485 Peter * phyint is *not* in an IPMP group, then its IPSQ will refer to the IPSQ's 1047 8485 Peter * "own" xop (ipsq_ownxop). If a phyint *is* part of an IPMP group, then its 1048 8485 Peter * IPSQ will refer to the "group" xop, which is shorthand for the xop of the 1049 8485 Peter * IPSQ of the IPMP meta-interface's phyint. Thus, all phyints that are part 1050 8485 Peter * of the same IPMP group will have their IPSQ's point to the group xop, and 1051 8485 Peter * thus becoming "writer" on any phyint in the group will prevent any other 1052 8485 Peter * writer on any other phyint in the group. All IPSQs sharing the same xop 1053 8485 Peter * are chained together through ipsq_next (in the degenerate common case, 1054 8485 Peter * ipsq_next simply refers to itself). Note that the group xop is guaranteed 1055 8485 Peter * to exist at least as long as there are members in the group, since the IPMP 1056 8485 Peter * meta-interface can only be destroyed if the group is empty. 1057 0 stevel * 1058 8485 Peter * Incoming exclusive operation requests are enqueued on the IPSQ they arrived 1059 8485 Peter * on rather than the xop. This makes switching xop's (as would happen when a 1060 8485 Peter * phyint leaves an IPMP group) simple, because after the phyint leaves the 1061 8485 Peter * group, any operations enqueued on its IPSQ can be safely processed with 1062 8485 Peter * respect to its new xop, and any operations enqueued on the IPSQs of its 1063 8485 Peter * former group can be processed with respect to their existing group xop. 1064 8485 Peter * Even so, switching xops is a subtle dance; see ipsq_dq() for details. 1065 0 stevel * 1066 8485 Peter * An IPSQ's "own" xop is embedded within the IPSQ itself since they have have 1067 8485 Peter * identical lifetimes, and because doing so simplifies pointer management. 1068 8485 Peter * While each phyint and IPSQ point to each other, it is not possible to free 1069 8485 Peter * the IPSQ when the phyint is freed, since we may still *inside* the IPSQ 1070 8485 Peter * when the phyint is being freed.
