From 1134723e96f6e2abcf8bfd7a2d1c96fcc323ef35 Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Wed, 14 Jan 2009 14:13:56 +0100 Subject: [CVE-2009-0029] Remove __attribute__((weak)) from sys_pipe/sys_pipe2 Remove __attribute__((weak)) from common code sys_pipe implemantation. IA64, ALPHA, SUPERH (32bit) and SPARC (32bit) have own implemantations with the same name. Just rename them. For sys_pipe2 there is no architecture specific implementation.
