From 0676c3a34c7bf12b33f8f5efb92476f4ffc7f20e Mon Sep 17 00:00:00 2001 From: Rich Felker Date: Tue, 11 Sep 2018 15:58:46 -0400 Subject: use wrapper headers to hide most namespaced/internally-public symbols not all prefixed symbols can be made hidden. some are part of ABI-compat (e.g. __nl_langinfo_l) and others are ABI as a consequence of the way copy relocations for weak aliases work in ELF shared libraries. most, however, can be made hidden. with this commit, there should be no remaining unintentionally visible symbols exported from libc.so. --- src/include/unistd.h | 7 ++++--- 1 file changed, 4 insertions(+), 3 deletions(-) (limited to 'src/include/unistd.h') diff --git a/src/include/unistd.h b/src/include/unistd.h index 9cdf1d3e..6deb1bcc 100644 --- a/src/include/unistd.h +++ b/src/include/unistd.h @@ -5,8 +5,9 @@ extern char **__environ; -int __dup3(int, int, int); -int __mkostemps(char *, int, int); -int __execvpe(const char *, char *const *, char *const *); +hidden int __dup3(int, int, int); +hidden int __mkostemps(char *, int, int); +hidden int __execvpe(const char *, char *const *, char *const *); +hidden int __aio_close(int); #endif -- cgit v1.2.1
