Robert Watson 8c0fec805f Modify most routines returning 'struct ifaddr *' to return references ... rather than pointers, requiring callers to properly dispose of those references. The following routines now return references: ifaddr_byindex ifa_ifwithaddr ifa_ifwithbroadaddr ifa_ifwithdstaddr ifa_ifwithnet ifaof_ifpforaddr ifa_ifwithroute ifa_ifwithroute_fib rt_getifa rt_getifa_fib IFP_TO_IA ip_rtaddr in6_ifawithifp in6ifa_ifpforlinklocal in6ifa_ifpwithaddr in6_ifadd carp_iamatch6 ip6_getdstifaddr Remove unused macro which didn't have required referencing: IFP_TO_IA6 This closes many small races in which changes to interface or address lists while an ifaddr was in use could lead to use of freed memory (etc). In a few cases, add missing if_addr_list locking required to safely acquire references. Because of a lack of deep copying support, we accept a race in which an in6_ifaddr pointed to by mbuf tags and extracted with ip6_getdstifaddr() doesn't hold a reference while in transmit. Once we have mbuf tag deep copy support, this can be fixed. Reviewed by: bz Obtained from: Apple, Inc. (portions) MFC after: 6 weeks (portions)		2009-06-23 20:19:09 +00:00
