From 905775f198e8990dc8458d5879b934ebdc623ef4 Mon Sep 17 00:00:00 2001 From: "Anthony G. Basile" Date: Wed, 3 Jul 2013 17:59:32 -0400 Subject: libc/sysdeps/linux/common/sendfile.c: fix sendfile64 visibility Commit a83ea57a50 introduces code for falling back on sendfile64 when the sendfile syscall is not available. However, as written, that code leads to sendfile64 being globally hidden in situations where __NR_sendfile and __USE_LARGEFILE64 are defined. In this case, the flow executes strong_alias_untyped(sendfile,sendfile64) in libc/sysdeps/linux/common/sendfile.c and libc_hidden_proto(sendfile64) in include/sys/sendfile.h, but nowhere does it do libc_hidden_def(sendfile64). This patch adds the needed libc_hidden_def(sendfile64). This breaks, for example, xfsprogs on x86_64. Reported by mardok4 in IRC. Signed-off-by: Anthony G.
