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.
