Resolver code, brought in by pthreads (at least), uses if_* interfaces that weren't in POSIX before 2001, resulting in linknamespace failures. This patch changes those interfaces to be weak aliases of __if_* and makes the resolver use __if_* directly. Tested for x86_64 (testsuite, and that disassembly of installed shared libraries is unchanged by this patch). [BZ #17717] * inet/if_index.c (if_nametoindex): Rename to __if_nametoindex and define as weak alias of __if_nametoindex. Use libc_hidden_weak. (if_indextoname): Rename to __if_indextoname and define as weak alias of __if_indextoname. Use libc_hidden_weak. (if_freenameindex): Rename to __if_freenameindex and define as weak alias of __if_freenameindex. (if_nameindex): Rename to __if_nameindex and define as weak alias of __if_nameindex. * sysdeps/mach/hurd/if_index.c (if_nametoindex): Rename to __if_nametoindex and define as weak alias of __if_nametoindex. Use libc_hidden_weak. (if_freenameindex): Rename to __if_freenameindex and define as weak alias of __if_freenameindex. (if_nameindex): Rename to __if_nameindex and define as weak alias of __if_nameindex. (if_indextoname): Rename to __if_indextoname and define as weak alias of __if_indextoname. Use libc_hidden_weak. * sysdeps/unix/sysv/linux/if_index.c (if_nametoindex): Rename to __if_nametoindex and define as weak alias of __if_nametoindex. Use libc_hidden_weak. (if_freenameindex): Rename to __if_freenameindex and define as weak alias of __if_freenameindex. Use libc_hidden_weak. (if_nameindex_netlink): Use __if_freenameindex instead of if_freenameindex. (if_nameindex): Rename to __if_nameindex and define as weak alias of __if_nameindex. Use libc_hidden_weak. (if_indextoname): Rename to __if_indextoname and define as weak alias of __if_indextoname. Use libc_hidden_weak. * include/net/if.h [!_ISOMAC] (__if_nametoindex): Declare and use libc_hidden_proto. [!_ISOMAC] (__if_freenameindex): Likewise. * resolv/res_init.c (__res_vinit): Use __if_nametoindex instead of if_nametoindex. * conform/Makefile (test-xfail-XPG4/grp.h/linknamespace): Remove variable. (test-xfail-XPG4/pwd.h/linknamespace): Likewise. (test-xfail-UNIX98/aio.h/linknamespace): Likewise. (test-xfail-UNIX98/grp.h/linknamespace): Likewise. (test-xfail-UNIX98/pthread.h/linknamespace): Likewise. (test-xfail-UNIX98/pwd.h/linknamespace): Likewise. (test-xfail-UNIX98/sched.h/linknamespace): Likewise.
