https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=189268 --- Comment #9 from dreamcat4@gmail.com --- (In reply to Benjamin Kaduk from comment #8) > I do not see why it is believed to be correct behavior to blindly cast > addrinfo->ai_addr to type 'struct sockaddr_in *' without first checking that > addrinfo->ai_family is PF_INET (or that the sockaddr's sa_family is > AFS_INET); such a cast is expected to yield "nonsense" results when > ai_family is PF_INET6. I made the change you suggested. https://gist.github.com/dreamcat4/86706bba25c468fc0ecc For PF_INET6 hints, the returned structure says it is of type ai_family '0x1C' (which is '28' in decimal base 10). If we look in the header file '/usr/include/sys/socket.h', we see that returned type is: AF_ISDN :/ Maybe that aught to be a returned value of type '30' (0x1E) for PF_INET6. Since that was the type we actually requested? #define pseudo_AF_PIP 25 /* Help Identify PIP packets */ #ifdef __APPLE__ /*define pseudo_AF_BLUE 26 Identify packets for Blue Box - Not used */ #define AF_NDRV 27 /* Network Driver 'raw' access */ #endif #define AF_ISDN 28 /* Integrated Services Digital Network*/ #define AF_E164 AF_ISDN /* CCITT E.164 recommendation */ #define pseudo_AF_KEY 29 /* Internal key-management function */ #endif /* (!_POSIX_C_SOURCE || _DARWIN_C_SOURCE) */ #define AF_INET6 30 /* IPv6 */ #if !defined(_POSIX_C_SOURCE) || defined(_DARWIN_C_SOURCE) #define AF_NATM 31 /* native ATM access */ #ifdef __APPLE__ #define AF_SYSTEM 32 /* Kernel event messages */ -- You are receiving this mail because: You are the assignee for the bug.
