* include/ifaddrs.h: Define struct in6addrinfo. Add two more parameters to __check_pf. * sysdeps/unix/sysv/linux/check_pf.c: When using the netlink interface, determine whether IPv6 addresses are deprecated or temporary. Create array of those addresses. * inet/check_pf.c: Always tell caller there are no depracated and temporary addresses. * sysdeps/posix/getaddrinfo.c: Pretty printing. (struct sort_result): Add source_addr_flags field. (rfc3484_sort): Implement rule 3 and 7. (in6aicmp): New function. (getaddrinfo): Call __check_pf also when we need info about IPv6 source addresses. When creating array for sorting addresses, look up deprecated and temporary addresses returned by __check_pf and add flag if necessary. 2006-04-17 05:34:32 +08:00			`struct in6addrinfo`

Cache network interface information Whenever getaddrinfo needed network interface information it used the netlink interface to read the information every single time. The problem is that this information can change at any time. The patch implements monitoring of the network interfaces through nscd. If no change is detected the previously read information can be reused (which is the norm). This timestamp information is also made available to other processes using the shared memory segment between nscd and those processes. 2011-10-31 13:51:16 +08:00			`extern void __free_in6ai (struct in6addrinfo *in6ai) attribute_hidden;`
