From 35281b18b8f9907213410ebbebc23c71b2ec357a Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Mon, 2 May 2016 23:20:33 +0000 Subject: Fix fcntl.h timespec namespace (bug 20023). fcntl.h defines struct timespec if __USE_XOPEN || __USE_XOPEN2K8. But (a) the subsequent bits/stat.h include only needs it if __USE_XOPEN2K8 and (b) older standards did not allow struct timespec here. (It's allowed for newer standards by virtue of the permission to include symbols from sys/stat.h. But sys/stat.h is only required to provide struct timespec from the 2008 edition of POSIX onwards, and permitted by the 2004 TC to the 2001 edition in anticipation of the addition of nanosecond timestamp support to struct stat in the 2008 edition.) This patch limits the timespec definition to the __USE_XOPEN2K8 case, that being the only case where it is actually needed for the include. Tested for x86_64 and x86 (testsuite, and that installed stripped shared libraries are unchanged by the patch). [BZ #20023] * io/fcntl.h [__USE_XOPEN && !__USE_XOPEN2K8]: Do not include . * conform/Makefile (test-xfail-UNIX98/fcntl.h/conform): Remove variable. (test-xfail-XOPEN2K/fcntl.h/conform): Likewise. --- io/fcntl.h | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) (limited to 'io') diff --git a/io/fcntl.h b/io/fcntl.h index 1a92a8d738..cb706b4f0f 100644 --- a/io/fcntl.h +++ b/io/fcntl.h @@ -71,9 +71,11 @@ typedef __pid_t pid_t; #endif /* For XPG all symbols from should also be available. */ -#if defined __USE_XOPEN || defined __USE_XOPEN2K8 +#ifdef __USE_XOPEN2K8 # define __need_timespec # include +#endif +#if defined __USE_XOPEN || defined __USE_XOPEN2K8 # include # define S_IFMT __S_IFMT -- cgit 1.4.1
