The POSIX function scandir calls scandirat, which is not a POSIX function. This patch fixes this by making it use __scandirat and making scandirat a weak alias. There are no changes for scandir64 / scandirat64 because those are both _GNU_SOURCE-only functions so no namespace issue arises for them. Tested for x86_64 that the disassembly of installed shared libraries is unchanged by this patch. [BZ #17999] * dirent/scandir.c [!SCANDIR] (SCANDIRAT): Define to __scandirat instead of scandirat. * dirent/scandirat.c [!SCANDIRAT] (SCANDIRAT): Likewise. [!SCANDIRAT] (SCANDIRAT_WEAK_ALIAS): Define. [SCANDIRAT_WEAK_ALIAS] (scandirat): Define as weak alias of __scandirat. * include/dirent.h (scandirat): Do not use libc_hidden_proto. (__scandirat): Declare. Use libc_hidden_proto. * conform/Makefile (test-xfail-POSIX2008/dirent.h/linknamespace): Remove variable. (test-xfail-XOPEN2K8/dirent.h/linknamespace): Likewise.
