Fix getifaddrs, freeifaddrs namespace (bug 17668).
Various objects in glibc bring in ifaddrs.o (via references to __netlink_*) and thereby getifaddrs and freeifaddrs, which are not part of any standard supported by glibc. These should be weak aliases of __getifaddrs and __freeifaddrs; this patch makes them so. (The path by which these functions are brought in is Linux-specific, but it seems less confusing to make all versions of these functions weak aliases rather than only the Linux-specific versions that definitely need it.) Tested for x86_64 (testsuite, and that disassembly of installed shared libraries is unchanged by this patch). [BZ #17668] * inet/ifaddrs.c (getifaddrs): Rename to __getifaddrs and define as weak alias of __getifaddrs. Use libc_hidden_weak. (freeifaddrs): Rename to __freeifaddrs and define as weak alias of __freeifaddrs. Use libc_hidden_weak. * sysdeps/gnu/ifaddrs.c (getifaddrs): Rename to __getifaddrs and define as weak alias of __getifaddrs. Use libc_hidden_weak. (freeifaddrs): Rename to __freeifaddrs and define as weak alias of __freeifaddrs. Use libc_hidden_weak. * sysdeps/unix/sysv/linux/ifaddrs.c (getifaddrs): Rename to __getifaddrs and define as weak alias of __getifaddrs. Use libc_hidden_weak. (freeifaddrs): Rename to __freeifaddrs and define as weak alias of __freeifaddrs. Use libc_hidden_weak. * conform/Makefile (test-xfail-XOPEN2K/net/if.h/linknamespace): Remove variable. (test-xfail-POSIX2008/net/if.h/linknamespace): Likewise. (test-xfail-XOPEN2K8/net/if.h/linknamespace): Likewise.
