Fix gethostbyaddr in6addr_any, in6addr_loopback namespace (bug 18532).

2015-06-17T20:08:22Z

gethostbyaddr brings in references to in6addr_any and thereby in6addr_loopback, which aren't in all the standards containing gethostbyaddr (gethostbyaddr is in XPG4 and UNIX98, in6addr_any and in6addr_loopback are new in POSIX.1:2001). This patch fixes this by making those symbols into weak aliases (safe in this case, unlike for most data symbols, because these data symbols are const). Tested for x86_64 and x86 (testsuite, and comparison of disassembly of installed stripped shared libraries). Disassembly is unchanged for x86_64; for x86, I see some changes of stack offsets, but no other code generation changes or code size differences. [BZ #18532] * inet/in6_addr.c (in6addr_any): Rename to __in6addr_any and define as weak alias of __in6addr_any. Use libc_hidden_data_weak. (in6addr_loopback): Rename to __in6addr_loopback and define as weak alias of __in6addr_loopback. Use libc_hidden_data_weak. * include/netinet/in.h (__in6addr_loopback): Declare. Use libc_hidden_proto. (__in6addr_any): Likewise. * inet/gethstbyad_r.c (PREPROCESS): Use __in6addr_any instead of in6addr_any. * conform/Makefile (test-xfail-XPG4/netdb.h/linknamespace): Remove variable. (test-xfail-UNIX98/netdb.h/linknamespace): Likewise.

First steps to get conformtest fully working

Avoid memory leak in case realloc fails. Simplification for better code generation. Avoid deprecation warning because of libc_hidden_proto for inet6_option_alloc. * inet/inet6_option.c (option_alloc): Renamed from inet6_option_alloc. Made static. (inet6_option_alloc): New a simple wrapper around option_alloc. (inet6_option_append): Call option_alloc. * include/netinet/in.h: Remove libc_hidden_proto for inet6_option_alloc.

(CFLAGS-tst-align.c): Add -mpreferred-stack-boundary=4.
